    In 2024, a total of 27 309 cases of medication error (ME) from 484 hospitals in 27 provincial administrative regions were collected in the National Monitoring Network for Clinical Safe Medication. Among them, 279 (1.02%) were classified as grade A, 22 081 (80.86%) as grade B, 4 268 (15.63%) as grade C, 472 (1.73%) as grade D, 96 (0.35%) as grade E, 105 (0.38%) as grade F, 6 (0.02%) as grade H, and 2 (<0.01%) as grade I; no MEs of grade G occurred. Among the 27 030 patients involved in MEs of grade B to I, 15 124 (55.95%) were male and 11 906 (44.05%) were female; their ages were from 1 day to 104 years; 3 369 (12.46%) were children (<18 years old), 12 113 (44.81%) were young and middle-aged adults (≥18 to <60 years old), and 11 548 (42.72%) were elderly (≥60 years old). The top 3 contents of ME were wrong drug class (5 347 cases, 19.13%), wrong dosage (4 913 cases, 17.58%), and wrong administration frequency (3 429 cases, 12.27%). Among the 27 030 grade B-I MEs, the main person who triggered the event were physicians (18 703 cases, 69.19%) and pharmacists (6 343 cases, 23.47%). These MEs mainly occurred in clinics (11 009 cases, 40.73%), in hospital wards (7 393 cases, 27.35%), and in pharmacies (6 219 cases, 23.27%). The main persons who discovered the MEs were pharmacists (21 021 cases, 74.14%). The top 3 factors causing ME were lack of related pharmacologic knowledge (8 716 cases, 26.49%), tiredness (5 755 cases, 17.49%), and inexperienced skills (4 505 cases, 13.69%). A total of 209 patients were involved in severe MEs (grade E-I), including 133 (63.64%) males and 76 (36.36%) females, aged from 21 months to 94 years, of which 42 (20.10%) were children, 75 (35.88%) were young and middle-aged adults, and 92 (44.02%) were elderly. The top 3 diseases diagnosed in severe MEs were drug poisoning (41 cases, 19.62%), diabetes (34 cases, 16.27%), and hypertension (14 cases, 6.70%); the main person who triggered the MEs were patients and their families (135 cases, 64.59%); the MEs occurred mainly in patients′ houses (116 cases, 55.50%). Drug poisoning was mainly related to accidental ingestion by children, and MEs in patients with diabetes and hypertension were often related to issues on patient compliance. Based on the data of MEs in 2024, it was proposed to establish a better medication safety culture and improve the ME reporting situation in China, pay attention to the risks of misusing external drugs for internal use, children′s accidental ingestion and insulin-related MEs, strengthen the prevention of MEs related to look-alike sound-alike drugs, pay attention to the post administration management and the compliance education of home care for patients with chronic diseases, so as to improve the medication safety of patients in China.

    Objective To investigate off-label drug use and the incidence of adverse events (AE) in patients with nontuberculous mycobacterial (NTM) pulmonary disease, and to provide reference in standardization of off-label drug use in this population. Methods The medical records of NTM pulmonary disease patients in our hospital from January to December 2024 were retrieved based on the presence of "nontuberculous mycobacteria" in the diagnosis. The demographic characteristics of patients (gender, age), underlying diseases, identified NTM species, details of off-label prescribing (clinical medication indications and the name, duration and frequency of drugs), and the AE occurrence were collected. The utilization rate, AE incidence, and off-label use rate of the anti-NTM drugs were calculated. Results A total of 259 patients with NTM pulmonary disease were included in the analysis, including 125 males and 134 females, aged (61±11) years with a range of 20-83 years; 243 patients (93.8%) were complicated with underlying diseases, 99 cases (38.2%) of which had 2 or more underlying diseases. Among the 259 patients, the top 3 pathogenic bacteria in the sputum and bronchoalveolar lavage fluid were Mycobacterium intracellulare (126 cases, 48.6%), Mycobacterium abscessus (50 cases, 19.3%), and Mycobacterium avium (30 cases, 11.6%); 16 patients (6.2%) were co-infected with 2 strains. All of the 259 patients were treated with a combination therapy of 4 drugs without discontinuation at least 1 year after the negative sputum culture. All 259 patients had off-label drug use, mainly including off-label indication [98.8%(256/259)] and prolonged treatment duration(100%). Among the 259 patients, 17 kinds of off-label drugs were involved, and the top 5 in terms of usage frequency were ethambutol (182 cases, 70.3%), amikacin (141 cases, 54.4%), azithromycin (140 cases, 54.1%), clari- thromycin (135 cases, 52.1%), and rifabutin (106 cases, 40.9%). The overall AE incidence was 37.5% (97/259), mainly including gastrointestinal reactions [17.4% (45/259)], skin pruritus [12.0% (31/259)], and abnormal liver function [9.7% (25/259)]. The incidences of severe AE and AE involving 2 or more systems were 5.0% (13/259) and 17.4% (45/259), respectively. Conclusions Off-label drug use is prevalent in patients with NTM pulmonary disease, mainly characterized by off-label indications and prolonged treatment duration. A variety of drugs are involved, among which ethambutol, amikacin, macrolides, and rifabutin are the most common. The types of AE reported are all common, mainly including gastrointestinal reactions, allergic reactions, and abnormal liver function, with a low proportion of severe AE. However, off-label use carries inherent risks, it is necessary to strengthen therapeutic drug monitoring and management during the treatment of NTM pulmonary disease.

    Objective To evaluate potentially inappropriate medication (PIM) in hospitalized elderly patients with bacterial pneumonia, and explore its influencing factors. Methods It was a singlecenter cross-sectional study. The study focused on elderly patients with bacterial pneumonia who were admitted to Xuanwu Hospital, Capital Medical University from January 2018 to November 2022. Patients′ gender, age, weight, length of hospital stay, diagnosis at admission, physical examination, diagnosis at discharge, comorbidities, medications, and laboratory test results were extracted from hospital information system and electronic medical records. Medication use of patients included in the analysis during their hospitalization were evaluated according to the classification of PIMs in the 5 lists of the Beer′s criteria of American Geriatrics Society. Based on whether PIM occurred, the patients were divided into with PIM group and without PIM group. The clinical features between the 2 groups were compared and the influencing factors of PIM were analyzed using multivariable logistic regression. Results A total of 2 720 patients were included, in which 1 734 (63.75%) were male. The median age was 78 (70, 85) years and their ages ranged from 65 to 103 years. The number of drugs used per patient was 14 (10, 18) kinds, ranging from 1 to 57 kinds. The length of hospital stay was 12 (9, 17) days, ranging from 1 to 162 days. Charlson comorbidity index (CCI) was 6 (5, 8) points. Among the 2 720 patients, 1 894 (69.63%) experienced PIM, with a total of 6 166 cases of PIM. The top 3 drugs ranked by the number of PIM occurrence were antiplatelet agents (1 357 cases), benzodiazapine receptor agonists (956 cases), and antipsychotics (884 cases). The comparison of clinical characteristics between the 2 groups showed that differences in age, CCI, length of hospital stay, and number of medications between with PIM and without PIM patients were statistically significant (all P<0.001). Multivariable logistic regression results showed that CCI, length of hospital stay, and number of medications were independent influencing factors for PIM. The risk increased by 8% and 1% with one point increase in CCI and one day extension in length of hospital stay [odds ratio (OR)=1.08, 95% confidence interval (CI): 1.04-1.13, P<0.001; OR=1.01, 95%CI: 1.00-1.03, P=0.03]. PIM risk of patients with more than 15 concurrent medications had a 22.16 times higher PIM risk than those with less than 5 concurrent medications (OR=22.16, 95%CI: 14.15-34.72, P<0.001). Conclusions Hospitalized eldery patients with bacterial pneumonia who have more severe comorbidities, longer hospital stay, and multiple concomitant medications are at a higher risk of PIM occurrence. Rational medication use among these patients should be paid attention to in clinical practice.

    Objective To analyze the safety of pigments and inks commonly used in food and drug packaging materials. Methods The acute oral toxicity, skin irritation, and eye irritation tests in 4 different batches of pigment samples (YP-001 to YP-008) and one kind of ink (YP-009) were investigated by animal experiments. Median lethal dose (LD50), body weight, and stimulation intensity were used as detection indicators. The test sample with LD50>5 000 mg/kg was judged as practically non-toxicity, the test sample with skin irritation intensity of 0-<0.50 points and eye irritation intensity of 0-3 points were judged as no irritation. Bacterial reverse mutation test, in vitro mammalian chromosome aberration test, and mammalian erythrocyte micronucleus test were carried out on oil paint (YP-007). The number of revertant colonies, chromosome aberration rate, and erythrocyte micronucleus rate were used as the detection indexes. If the number of revertant colonies in each dose group in the test sample was less than 2 times of that in the blank control group, the chromosome aberration rate and erythrocyte micronucleus rate were not statistically significant compared with the negative control group, the test sample was judged to be negative. Results The acute oral toxicity test showed that the weight of mice in different test groups was not reduced, and the LD50 was more than 5 000 mg/kg, so the samples were judged to be practically non-toxic, no irritation to skin and eyes of rabbits. The bacterial reverse mutation test showed that the results in 5 different dose groups and 5 repeated dose groups of oil paint test samples were all negative. The in vitro mammalian chromosome aberration test showed that the results in 3 dose groups of oil paint test samples (5.0, 2.5 and 1.25 mg/ml) were all negative. The mammalian erythrocyte micronucleus test showed that the results in 3 dose groups of oil paint test samples (10.0, 5.0 and 2.5 mg/kg) were all negative. Conclusions The test samples of 4 different batches of pigments and one kind of ink are practically non-toxic and free of skin and eye irritation. The oil paint (YP-007) has no genotoxicity and potential carcinogenicity in vivo and in vitro.

    Objective To understand the application situation and role of prescription sequence symmetry analysis (PSSA) in pharmacovigilance. Methods The relevant databases at home and abroad were searched (up to April 30, 2024), and the original articles using PSSA as the research method were collected. The basic information of the literature (first author, publication year, country, etc.), the purpose and main content of the study, the index drugs as well as the marker drugs or medical diagnoses involved in the adverse drug reactions (ADRs) were extracted. Descriptive statistical analysis was carried out. Results A total of 66 articles were included in the analysis. The first article was published in 1996, the number of articles published in recent years has increased significantly, and those published after 2016 accounted for 68.2% (45/66). The top 3 countries in terms of published literature quantity were the United States, Denmark, and Japan. The index drugs most commonly studied were those for the cardiovascular system and the neuropsychiatric system, in 18 and 14 articles respectively. The drugs studied in 3 or more papers were hypolipidemic drugs, antihypertensive drugs, antipsychotics, antiepileptics, proton pump inhibitors, hypoglycemic drugs and anticoagulants. The targeted ADRs/diseases most studied were those about the neuropsy- chiatric system (in 13 studies), followed by those about the endocrine and metabolic system (in 12 studies). The research objective in 47 articles was to explore the association between index drugs and ADRs/diseases through PSSA. Finally, the associations between 21 ADRs and index drugs were identified in 24 articles, of which 9 were new ADRs not recorded in drug instructions; benefits or potential preventive and therapeutic effects of index drugs on certain diseases were found in 7 studies. Ten studies were conducted to explore ADR information of specific drugs or detect suspicious drugs that cause specific ADRs, and some correlation signals between drugs and ADRs that previously unknown were detected. Nine studies evaluated the prescribing cascades, including the use of antitussive drugs after ACEI, the prescribing cascades related to drug-induced lower urinary tract symptoms and edema, the prescription cascades of statins, and the prescribing cascade relic. Conclusion PSSA is a useful method for identifying potential prescribing cascades and mining ADR signals using medical prescription databases, especially suitable for the safety monitoring of long-term medication for chronic diseases and the signal detection of ADR that causal relationships are difficult to determine.

    Objective To explore the effect of contezolid on platelet count in patients with severe pneumonia and analyze the risk factors. Methods The study was designed as a retrospective case-control study. The research subjects were selected from patients with severe pneumonia who were admitted to the Department of Respiratory and Critical Care Medicine of Shaanxi Provincial People′s Hospital from July 1, 2022 to November 30, 2024 and were treated with contezolid or linezolid. The clinical data of patients were collected and the incidence of thrombocytopenia [platelet count (PLT)<100×109/L after medication], the PLT before and at 1 week of treatments, and the lowest PLT value during treatments were compared in patients treated with contezolid and linezolid. The patients were divided into 2 groups based on whether contezolid- related thrombocytopenia occurred. The clinical characteristics of the patients were compared, and the independent risk factors of contezolid-related thrombocytopenia were analyzed by binary logistic regression method. Results A total of 175 patients were included, among whom 73 received contezolid and 102 received linezolid. There was no statistically significant difference in PLT between the 2 groups before medication (P=0.364). Compared with patients treated with linezolid, the incidence of thrombocytopenia in patients treated with contezolid was lower [19.2% (14/73) vs. 40.2% (41/102)], and the PLT at 1 week of treatments and the lowest value of PLT during treatments were higher. The differences were all statistically significant (all P<0.05). Compared with patients without contezolid-related thrombocytopenia(59 patients), patients who develo-ped thrombocytopenia after using contezolid had a longer duration of contezolid medication, lower PLT and creatinine clearance rate before medication, and higher procalcitonin and serum creatinine levels before medication. All these differences were statistically significant (all P<0.05). The results of binary logistic regression analysis showed that lower PLT [odds ratio (OR)=0.971, 95% confidence interval (CI): 0.950-0.992, P=0.008] and higher procalcitonin level (OR=7.292, 95%CI: 1.067-49.814, P=0.043) before medication and longer duration of contezolid medication (OR=1.165, 95%CI: 1.002-1.355, P=0.046) were the independent risk factors of contezolid-related thrombocytopenia. Conclusions Compared with linezolid, contezolid has a relatively safer profile in the treatment of patients with severe pneumonia and the risk of thrombocytopenia after medication is lower. Patients with lower PLT and higher procalcitonin levels before medication, and those with a longer duration of contezolid medication have a higher risk of contezolid-related thrombocytopenia and should be closely monitored.

    Objective To evaluate the consistency of steady-state blood trough concentration of vancomycin and minimum inhibitory concentration to the area under the serum concentration-time curve (AUC/MIC) and promote the rational use of vancomycin. Methods It was a single center retrospective study. The clinical data of patients admitted to Xuanwu Hospital, Capital Medical University from January 1, 2019 to December 31, 2020, who were treated with vancomycin and met the inclusion criteria, were collected. Vancomycin calculator was used to calculate AUC/MIC. According to the steady-state blood trough concentration and AUC/MIC standards, the patients were divided into not meeting standard group, meeting standard group, and exceeding standard group, respectively. The standard-reaching status of steady-state blood trough concentration and AUC/MIC in each group was evaluated, as well as the consistency in patients under the 2 different grouping methods. The patients who met the AUC/MIC standard were divided into not meeting standard group, meeting standard group, and exceeding standard group based on steady-state blood trough concentration. The anti-infection efficacy and incidence of vancomycin-associated acute kidney injury (VA-AKI) were evaluated between the different groups to assess clinical effectiveness and safety. Results A total of 153 patients were included in the study. Among them, 98 (64.1%) patients were male, with age of 61.0 (53.0, 73.0) years, body mass index of 23.9 (21.5, 27.0) kg/m2, creatinine clearance rate of 107.2 (84.1, 147.0) ml/min, and acute physiology and chronic health evaluationⅡscore of 9.0 (6.0, 14.0) points. Among the 153 patients, the AUC/MIC and steady-state blood trough concentration did not meet standards in 86 cases, met the standards in 17 cases, and exceeded the upper limit of the standards in 14 cases; the results were consistent in 117 cases for both methods, and the consistency rate was 76.5%; the results were inconsistent in 36 patients (23.5%). Among the 36 patients, the steady-state blood trough concentration did not meet the standard in 34 cases [with initial steady-state blood trough concentration of 13.9 (12.8, 14.4) mg/L], while the AUC/MIC met the standard [437 (420, 471)]. AUC/MIC met the standard in 51 patients (33.3%), of which 34 had the steady-state blood trough concentration of less than 15.0 mg/L, and 17 had the concentration of 15.0-20.0 mg/L; the efficacy of anti-infection was 88.2% and 13/17, respectively, the incidence of VA-AKI was 2.9% and 1/17, respectively; the difference was not significant (all P>0.05). No patients had the steady-state blood trough concentration over than 20.0 mg/L. Conclusions The consistence between steady-state trough concentration of vancomycin and AUC/MIC is 76.5%, which is acceptable. For those who meet the AUC/MIC standard for vancomycin, even if the steady-state blood trough concentration is less than 15.0 mg/L, as long as the AUC/MIC meets the standard, the efficacy and safety can be guaranteed.

    Objective To mine the drugs that may cause capillary leak syndrome (CLS), and evaluate the risk of CLS, and provide reference for safe and rational use of drugs in clinic. Methods Adverse event (AE) reports with the preferred term "capillary leak syndrome" from the 1st quarter of 2004 to the 4th quarter of 2023 were collected by searching US Food and Drug Administration Adverse Event Reporting System (FEARS) database. Reporting odds radio (ROR) method and proportional reporting ratio (PRR) method were used to mine the AE risk signals. Drugs with report number ≥3, lower limit of the 95% confidence interval (CI) of ROR value >1, PRR ≥2, χ2 ≥4 were grouped and classified according to the Anatomical Therapeutic Chemical Classification (ATC) system. The top 20 drugs in ROR values were selected, and a risk assessment for drugs potentially causing CLS was performed by reviewing drug labels, adverse reaction datasets, and relevant literature. Results A total of 1 033 AE reports related to CLS were collected, involving 558 primary suspected drugs associated with CLS. The top 5 types of drugs that the most commonly causing CLS were antineoplastic and immunomodulating agents, systemic hormonal preparations, anti-infectives for systemic uses, cardiovascular system, and alimentary tract and metabolism. The risk assessment results showed that 13 drugs of the top 20 drugs in signal intensity (clofarabine, gemcitabine, interleukin-3, denileukin diftitox, dinutuximab, filgrastim, trabectedin, cytarabine, busulfan, docetaxel, trastuzumab, vildagliptin and melphalan) were high-risk drugs causing CLS, among which cytarabine, docetaxel, busulfan, trastuzumab, vildagliptin, and melphalan were not recorded to cause CLS in the labels. The other 7 drugs (asparaginase, fludarabine, amphotericin B, bosutinib, daunorubicin, ponatinib, and bleomycin) were low-risk drugs causing CLS. Conclusions Thirteen drugs are high-risk drugs that may cause CLS, among which cytarabine, docetaxel, busulfan, trastuzumab, vildagliptin and melphalan are not recorded causing CLS in the labels. It is suggested that clinicians and pharmacists should be vigilant against high-risk drugs, especially those not recorded causing CLS in the labels.

    Objective To observe the efficacy and safety of adrenocorticotropic hormone (ACTH) therapy in children with steroid dependent nephrotic syndrome (SDNS)/frequently relapsed nephrotic syndrome (FRNS). Methods The clinical data of children with SDNS/FRNS who received treatment with prednisone acetate tablets were retrospectively collected from June 2019 to June 2023 in the Nephrology Department of Xi′an Children′s Hospital. The children were divided into glucocorticoid+ACTH group and glucocorticoid group, according to whether ACTH was used or not. The differences in cortisol, total cholesterol and 24 hour urinary protein quantity between 2 groups of children at baseline and follow-up endpoints were compared, and the effectiveness (the proportion of no recurrence and discontinuation of glucocorticoid) and occurrence of adverse reactions were evaluated. Results A total of 39 patients with SDNS/FRNS were included in this study, with 21 cases in the glucocorticoid+ACTH group and 18 cases in the glucocorticoid group. Among the 39 children, there were 33 cases of SDNS and 6 cases of FRNS, respectively. The proportion of baseline low cortisol levels was 76.9% (30/39). The proportion of cortisol levels returning to normal after ACTH treatment in the glucocorticoid+ACTH group was 76.2% (16/21). The baseline and follow-up endpoint for cortisol levels in the glucocorticoid+ACTH group were 28.0(19.8, 51.5) μg/L and 79.9(58.9, 113.0) μg/L, respectively. The baseline and follow-up endpoint for cortisol levels in the glucocorticoid group were 21.0(15.8, 37.4) μg/L and 25.3(18.2, 51.4) μg/L, respectively. In the 2 groups of cortisol levels, there was statistically significant difference in the interaction effect between time and group (Wald χ2=11.595, P=0.001), there was a statistically significant difference at the follow-up endpoint between the 2 groups (Wald χ2=19.462, P<0.001), and the difference was statistically significant in the time effect of the glucocorticoid+ACTH group (Wald χ2=21.100, P<0.001). The baseline and follow-up endpoint for total cholesterol in the glucocorticoid+ACTH group were 4.95(4.23, 5.26) mmol/L and 4.38(4.04, 5.24) mmol/L, respectively. The baseline and follow-up endpoint for total cholesterol in the glucocorticoid group were 4.80 (4.17, 5.28) mmol/L and 5.74 (5.04, 6.88) mmol/L, respectively. In the 2 groups of total cholesterol, there was statistically significant difference in the interaction effect between time and group (Wald χ2=9.842, P=0.002), there was statistically significant difference at the follow-up endpoint between the 2 groups(Wald χ2=12.187,P<0.001), the difference was statistically significant between the 2 groups in the time effect at baseline and the follow-up endpoint (glucocorticoid+ACTH group: Wald χ2=6.488, glucocorticoid group: Wald χ2=7.112; all P<0.05). The baseline and follow-up endpoint for 24 hour urinary protein quantity in the glucocorticoid+ACTH group were 115(105,128) mg/d and 121(113,128) mg/d, respectively. The baseline and follow-up endpoint for 24 hour urinary protein quantity in the glucocorticoid group were 118(113,125) mg/d and 138(119,2 100) mg/d, respectively. In the 2 groups of 24 hour urinary protein quantity, there was statistically significant difference in the interaction effect between time and group (Wald χ2=7.743, P=0.005), there was statistically significant difference at the follow-up endpoint between the 2 groups (Wald χ2=7.779, P=0.005), and the difference was statistically significant in the time effect of the glucocorticoid group (Wald χ2=13.331, P<0.001). The proportion of no recurrence (17/21) and discontinuation of oral glucocorticoid (16/21) in the glucocorticoid+ACTH group were higher than those in the glucocorticoid group (the proportion were both 6/18), and the differences between the 2 groups were statistically significant (the chi square values were 9.084 and 7.240, respectively; all P<0.01). No adverse reactions occurred in the glucocorticoid group. The incidence of adverse reactions in the glucocorticoid+ACTH group was 14.3% (3/21), of which 2 cases developed generalized urticaria and 1 case developed hypertension. Conclusions ACTH has a good efficacy and safety in children with SDNS/FRNS. The results of this study need to be further validated by increasing the sample size and conducting multicenter studies.

    Objective To systematically evaluate the incidence and risk factors of acute kidney injury (AKI) induced by vancomycin in pediatric patients. Methods Databases of PubMed, Embase, The Cochrane Library, Web of Science, CNKI, Wanfang, VIP, Chinese Biomedical Database (CBM) were searched and articles about the risk factors of AKI induced by vancomycin in pediatric patients from inception to June 2024 were collected. Quality assessment was performed using the Newcastle-Ottawa Scale (NOS) for the included studies. Meta-analysis of the data for relevant exposure factors extracted from the included literature was conducted using Rev Man 5.4. The strength of association between the exposure factors and AKI was expressed using the odds ratio (OR) and its 95% confidence interval (CI). Results A total of 13  studies were entered, involving 11 073 patients. Of them, 1 388 patients were in AKI group and 9 685 patients in non-AKI group. The incidence of AKI was 12.53%, ranging from 4.62% to 27.07%. The quality evaluation results showed that the 13 documents were all of high-quality (NOS score ≥7 points). Meta-analysis showed that admission to intensive care unit (ICU) (OR=2.39, 95%CI: 1.59-3.59, P<0.001), vancomycin using time ≥7 d (OR=2.19, 95%CI: 1.44-3.34,P=0.003), vancomycin steady-state trough concentration ≥15 mg/L (OR=2.98, 95%CI: 2.22-4.01, P<0.001), combined with nephrotoxic drugs ≥2 kinds (OR=2.92, 95%CI=1.84-4.64, P<0.001), combined with piperacillin sodium and tazobactam sodium (OR=2.71, 95%CI: 1.72- 4.27, P<0.001), combined with carbapenem (OR=2.36, 95%CI: 1.36-4.10, P=0.002), combined with aminoglycosides (OR=1.78, 95%CI: 1.35-2.35, P<0.001), combined with loop diuretics (OR=3.16, 95%CI: 2.36- 4.23, P<0.001), combined with amphotericin B (OR=2.26, 95%CI: 1.35-3.79, P=0.002), combined with contrast medium (OR=2.34, 95%CI: 1.04-5.25, P=0.040), and combined with aciclovir (OR=1.74, 95%CI: 1.04-2.84, P=0.030) were all risk factors of AKI induced by vancomycin in pediatric patients. Conclusions The incidence of vancomycin-related AKI in pediatric patients was 12.53%. Admission to ICU, vancomycin trough concentration ≥15 mg/L, medication time ≥7 d, and concomitant use of ≥2 nephrotoxic drugs and etc.were risk factors of vancomycin-related AKI.

    Objective To explore the differences on contraindication information for children in domestic and foreign drug instructions, and provide reference for improving the relevant information in Chinese drug insert sheets. Methods Chinese drug insert sheets of chemicals and biological products contained in the China Pharmacopoeia 2020 and those of the western medicines in the 2023 China′s Basic Medical Insurance, Work-related Injury Insurance and Childbirth Insurance Drug Catalog were collected; drugs that were marked as contraindication for children were selected and relevant contraindication information in the Chinese drug insert sheets was collected. Instructions of the above-mentioned drugs approved by the U.S. Food and Drug Administration (English labels) were also collected, and the information on pediatric medication was reviewed and compared with the Chinese drug insert sheets. Results A total of 222 drugs were labeled as contraindication for children in the Chinese drug insert sheets, of which 149 were available for their English labels; 123 drugs (17.5%) were not labeled as contraindication for children in English labels, and 26 (82.5%) were labeled. The 123 drugs that were not labeled as contraindication for children in the English labels included the following conditions: 58 were labeled as contraindication for children of some age in the Chinese drug insert sheets but not in the English labels, and relevant medication information was provided; 40 were labeled as contraindication for children of some age group in the Chinese drug insert sheets but was described as the effectiveness and safety of the use for children have not yet been determined for this age group in the English labels; 13 were labeled as contraindication for children in the Chinese drug insert sheets, but the medication information on children in the English labels was not clear or missing; 12 were labeled as contraindicated for children in Chinese drug insert sheets but not in the English labels, only expressed as not yet determined or not recommended for use, etc., with inconsistent age group. Among the 26 drugs labeled as contraindication for children in both Chinese and English instructions, the contraindication age group were the same in above 2 instructions for 20 drugs, and were inconsistent for the other 6 drugs; reasons for contraindication were described in both the 2 instructions for 17 drugs (13 were consistent, 4 were inconsistent), only in English labels for 8 drugs, and only in Chinese drug insert sheets for 1 drug. Conclusions Many drugs are labeled as contraindication for children in Chinese drug insert sheets, but reasons for contraindication are rarely explained. Differences in children′s age in contraindications exist for some drugs between the Chinese drug insert sheets and English labels. The information on contraindications for children in Chinese drug insert sheets still needs to be further improved.

    Adverse drug reaction (ADR) is an important problem in clinical diagnosis and treatment, and basic research related to ADR is essential. Exploring the mechanism of ADR through basic research can provide a theoretical basis for formulating effective prevention strategies and targeted treatment programs for ADR; many safety problems found in the process of clinical medication can be effectively verified and solved through basic research, such as the dose?response (toxicity) relationship of drugs and drug interactions; basic research related to drug toxicity is an indispensable key link in the process of drug research and development, and its research results are directly related to the safety of candidate compounds and the feasibility of clinical application. At present, there is a limited amount of literature on the basic research related to the mechanism of ADR in China. It is hoped that more researchers will pay attention to basic research related to ADR and drug safety, and promote the development of this field to a higher level.

    Objective To explore the role of glutathione peroxidase 4 (GPX4)-dependent ferroptosis in diclofenac-induced kidney injury. Methods Human kidney tubular epithelial cells (HK-2 cells) were cultured and then divided into 3 groups: control group, diclofenac group, and iron death inhibitor ferrostatin-1 (Fer-1) group. The same amount of 1% Fer-1 (final concentration 10 μmol/L) and phosphate buffered saline was respectively added to cells in the Fer-1 group and the other 2 groups. After 48 hours of culture, diclofenac 200 μmol/L was added to cells in the diclofenac group and the Fer-1 group. The cell viability of each group was detected by cell counting kit-8 (CCK-8). The cell cycle, apoptosis and intracellular reactive oxygen species (ROS) levels were detected by flow cytometry. The levels of intracellular iron ion, lactate dehydrogenase (LDH), malondialdehyde (MDA) and GPX4 were detected by enzyme-linked immunosorbent assay. The expression level of GPX4 was detected by Western blotting method. Results Compared with the control group, the cell viability and G1 phase cell percentage of the diclofenac group were significantly lower, and compared with the diclofenac group, those were significantly higher (all P<0.05). The apoptosis rate of diclofenac group was significantly higher than that of the control group (P<0.05), but there was no significant difference in apoptosis rate between Fer-1 group and diclofenac group (P>0.05). Compared with the control group, the intracellular ROS, iron content, LDH, and MDA levels were significantly higherin the diclofenac group, while the expression level of GPX4 was lower (all P<0.05). However, the ROS, iron content, LDH, and MDA levels in the Fer-1 group were lower than those in the diclofenac group, while GPX4 expression was higher than that in the diclofenac group (all P<0.05). Conclusion Diclofenac can induce ferroptosis in HK-2 cells and inhibiting the ferroptosis can alleviate cell injury, suggesting that GPX4-dependent ferroptosis may be involved in kidney injury induced by diclofenac.

    Objective To explore the effect of Shenxianling granules on the pharmacokinetics of ondansetron. Methods A method for detecting the plasma concentration of ondansetron using highperformance liquid chromatography (HPLC) was established. The reliability of the method was validated through specificity, linear relationship, precision, stability, repeated experiments, and sample recovery rate testing. Thirty six healthy male New Zealand rabbits were randomly divided into 2 groups, with 18 rabbits in each group. Rabbits in the single ondansetron group (single drug group) received intravenous injection of ondansetron 0.92?mg/kg through the ear vein. Rabbits in the Shenxianling granules combined with ondansetron group (combination drug group) were firstly given 575 mg/kg of Shenxianling granules by gavage continuously for 10 days, and on the morning of the 11th day, ondansetron 0.92?mg/kg was intravenously injected. Blood samples were collected before administration and at 5 minutes, 10?minutes, 20 minutes, 30 minutes, 45 minutes, 1 hour, 2 hours, 4 hours, 5 hours, 6 hours, 7 hours, 8 hours, 10 hours and 24 hours after administration of ondansetron. The blood concentration of ondansetron was detected using HPLC method and pharmacokinetic parameters were calculate. Results Two New Zealand rabbits in the combination drug group developed agitation and cough, and then died on the second and fifth day of gavage, respectively. Therefore a total of 18 and 16 rabbits in the single drug group and the combination drug group completed the experiment, respectively. After ondansetron administration, the plasma concentration of ondansetron increased rapidly in the single drug group and remained at low levels in the combination drug group. From 5 minutes to 10 hours after administration, the plasma concentration of ondansetron at the 13 blood sampling time points in the combination drug group was significantly lower than that in the single drug group, and the differences were statistically significant (all P<0.001). Compared with the single drug group, the plasma clearance half?life of ondansetron in the combination drug group was significantly prolonged, the peak time, peak concentration, concentration at the last time and area under the curve (AUC) were all significantly reduced, and the percen- tage of residual or extrapolated area to the overall AUC, apparent volume of distribution, and clearance/bioavailability ratio were significantly increased; the differences were statistically significant (all P<0.001). Conclusions There is a significant interaction between Shenxianling granules and ondansetron, leading to a decreased plasma concentration of ondansetron. The mechanism may be related to Shenxianling granules altering the tissue distribution of ondansetron within the body.

    Objective To explore the biodistribution characteristics of mixed activated killer (MAK) immune cells in immunodeficient mice after administration. Methods Ninety-six immune immunodeficient (NOG) mice (half male and half female) were equally divided into MAK cell group and solvent control group. The MAK cell group mice were injected with DiR-labeled MAK cells via the tail vein, while those in the solvent control group were injected with an equal amount of solvent via the tail vein. The number of MAK cells in the peripheral blood of mice was detected using a flow cytometry at 11 time points from 15 minutes to 84 days after administration. The distribution of MAK cells in mice was measured using in vivo bioluminescence imaging at 18 time points from 5 minutes to 84 days after administration. And at 8 time points from 3 hours to 84 days after administration, the heart, liver, spleen, lungs, kidneys, brain, stomach, duodenum, colon, bone marrow, fat, skeletal muscle, testes/uterus, epididymis/ovary, and blood were collected from corresponding mice. The DNA levels of MAK cells in blood and various organs of these mice were detected using fluorescence real time quantitative polymerase chain reaction (qPCR) method. Results The flow cytometry results showed that MAK cells could be detected in the peripheral blood of mice 15 minutes after administration, and the highest number of MAK cells in blood appeared during 3 hours to 1 day. By 14 days after administration, MAK cells were almost undetectable in peripheral blood of mice. In vivo bioluminescence imaging results showed that the fluorescence intensity of MAK cells in mice was strongest on days 1 and 2 after administration, and MAK cells were mostly distributed in the liver, spleen, lung, and leg bone of mouse. The qPCR detection results showed that MAK cells were mainly distributed in the spleen and lungs. High levels of MAK cell DNA amplification were observed in organs such as the spleen and lungs 28-56 days after administration, and a certain amount of MAK cell DNA could still be detected in organs of mice such as the spleen at 84 days. Conclusions After administration, MAK cells were mainly distributed in the spleen, lung, liver and other organs of NOG mice. From 28 to 56 days after administration, MAK cells are significantly activated and proliferate, and a certain amount of MAK cell DNA can still be detected in the spleen and other organs after 84 days in mice.

    Objective To analyze the occurrence and influencing factors of adverse reactions in patients with inflammatory bowel disease (IBD) during the long-term treatment with vedolizumab (VDZ). Methods The study was a retrospective observational design. The study subjects were selected from patients who long-termly used VDZ to treat moderate-to-severe active IBD in Tianjin Medical University General Hospital from February 1, 2021 to December 31, 2023. Clinical data of patients were collected through the hospital system of clinical pharmacy management, including general information, IBD condition, VDZ maintenance treatment plan, combination of drugs, laboratory test results, etc. The adverse reactions of VDZ were screened and their clinical manifestations, severity, intervention and outcomes were analyzed descriptively. The patients were divided into 2 groups according to whether VDZ adverse reactions occurred, and the differences in clinical data between them were compared; the influencing factors of adverse reactions were analyzed by multivariate logistic regression method. Results A total of 142 patients were included in the study, including 81 males and 61 females, aged (37.6±6.4) years with a range from 18 to 57 years. There were 103 patients (72.5%) developed VDZ adverse reactions, which mainly involved skin (52 patients, account for 50.5%), digestive system (33 patients, account for 32.0%) and respiratory system (18 patients, account for 17.5%). All 103 patients did not stop VDZ treatment, and the adverse reaction symptoms disappeared or were relieved after symptomatic treatments. Compared with patients without VDZ adverse reactions, the age of patients with VDZ adverse reactions were higher [(39.5±5.4) years vs. (32.4±6.7) years], and the proportions of patients with chronic relapsing clinical type [65.0%(67/103) vs. 41.0%(16/39)], severe disease activity [60.2%(62/103) vs. 33.3%(13/39)], combined drug use [67.0%(69/103) vs. 46.2%(18/39)], and injecting VDZ once every 4 weeks during maintenance treatment [27.2%(28/103) vs. 10.3%(4/39)] in the group were larger, with statistical significance (all P<0.05). Multivariate logistic regression analysis showed that the chronic relapsing clinical type [odds ratio (OR)=1.012, 95% confidence interval (CI): 1.001-1.028, P=0.002], severe disease activity (OR=1.096, 95%CI: 1.010-1.158, P=0.040), combination drugs (OR=1.035, 95%CI: 1.003-1.122, P=0.041), VDZ maintenance therapy injection interval of 4 weeks (OR=1.014, 95%CI: 1.002-1.113, P=0.005) were the risk factors for VDZ adverse reactions. Conclusions Among IBD patients receiving long-term treatment of VDZ, the incidence of adverse reactions of VDZ was 72.5%, mainly involving skin, digestive system and respiratory system. Symptomatic treatments could be given, and the prognosis was good. Patients with chronic relapsing clinical type, severe disease activity, com- bination therapy, and shorter VDZ maintenance injection interval were at higher risk of adverse reactions.

    Objective To explore the clinical features of nivolumab-induced Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN). Methods Relevant databases at home and abroad (as of December 31, 2023) were searched to collect case reports of nivolumab-induced SJS/TEN, and the demographic characteristics, nivolumab application, combination drugs, clinical manifestations, intervention measures, and outcomes were extracted and analyzed descriptively and statistically. Results A total of 27 case reports were included and 29 patients were enrolled in the study, including 18 males and 11 females. The age ranged from 45 to 86 years, with an average age of 67 years. The primary diseases were mainly melanoma, stomach cancer, and lung cancer. Twelve patients had records of nivolumab administration, and the dosage was within the recommended range in the labels; 13 patients had records of combination drugs, mainly other antineoplastic drugs, hypoglycemic drugs, antihypertensive drugs, lipid-regulating drugs, etc. The time from using nivolumab to the diagnosis of SJS/TEN was 7 d to 3 years, and 20 patients were <8 weeks. The clinical manifestations were mainly diffuse erythema, flaky skin peeling and erosion, mucosal involvement, etc. Sixteen patients had skin biopsy records, all of which met the histopathological characteristics of SJS/TEN. After the diagnosis of SJS/TEN, 17 patients discontinued nivolumab and received symptomatic treatments, of which 15 patients had improved skin symptoms, one patient had worsened skin symptoms, and one patient had no record of skin outcome; 12 patients had no record of whether or not discontinuing nivolumab, of which 8 patients had improved skin symptoms, 2 patients had worsened skin symptoms, one patient had no record of skin outcome, and one had no record of prognosis. One patient rechallenged nivolumab, severe SJS/TEN recurred. Thirteen of 29 patients died. Of them, 1 died due to cardiac arrest, 4 due to worsened skin rash, and 8 due to primary disease progression. Conclusions SJS/TEN caused by nivolumab mostly occurs within 8 weeks of treatment, and the clinical manifestations were similar to those caused by other drugs. The mortality rate of nivolumab-induced SJS/TEN is high, and skin rash could be improved after withdrawal of nivolumab and symptomatic treatments.

    Objective To mine the risk signals of adverse events (AEs) in mavacamten treatment for hypertrophic cardiomyopathy, and provide reference for safe use of the drug in clinic. Methods AE reports on mavacamten from June 2022 to June 2024 were collected by searching US Food and Drug Adminis- tration Adverse Event Reporting System (FAERS) database. AEs were classified and standardized according to the system organ class (SOC) and preferred term (PT) of Medical Dictionary for Regulatory Activities version 26.1. Reporting odds ratio (ROR) method and comprehensive standard method of the UK Medicines and Healthcare Products Regulatory Agency (MHRA) were used to mine the AE risk signals. An AE that simultaneously met the criteria of ≥3 reports, lower limit of the 95% confidence interval (CI) of ROR >1, PRR ≥2, and χ2 ≥4 was defined as a risk signal. Descriptive statistical analysis on signals was performed. Results A total of 1 041 AE reports were collected, involving 47 PTs and 12 SOCs. The top 10 risk signals based on the number of AE reports were dyspnea, dizziness, fatigue, atrial fibrillation, cardiac failure, palpitation, nasopharyngitis, chest pain, COVID-19, and weight increased. Except dizziness and heart failure, above AEs were not recorded in the label. The top 10 risks in signal intensity were acquired left ventricle outflow tract obstruction, transvalvular pressure gradient increased, cardiovascular symptom, echocardiogram abnormal, hypervolaemia, left ventricular failure, ejection fraction decreased, coronavirus infection, brain fog, and atrial fibrillation. Except cardiovascular symptom, left ventricular failure, and ejection fraction decreased, above AEs were not recorded in the label. Conclusions The AE risk signals of mavacamten in the treatment for hypertrophic cardiomyopathy recorded in the label are mainly heart failure and ejection fraction decreased. Clinicians and pharmacists should also be vigilant against risk signals not recorded in the lakel, such as atrial fibrillation, fatigue, nasopharyngitis, coronavirus infection, and brain fog, etc.

    Objective To analyze the risk factors of hypocalcemia in 3-5 stages of chronic kidney disease (CKD) patients with hyperkalemia and non-dialysis after potassium lowering therapy. Methods Clinical data of 3-5 stages of CKD patients with hyperkalemia and non-dialysis treated in Linyi Central Hospital from January 2019 to November 2024 were collected through the electronic medical record system. According to whether the corrected calcium level after potassium lowering treatments was lower than 2.12 mmol/L, the patients were divided into hypocalcemia group and non-hypocalcemia group. The gender, age, body mass index, primary disease, disease duration, comorbidity, use of potassium lowering drugs, concomitant medication, and blood potassium, corrected calcium, carbon dioxide binding capacity, blood magnesium, blood phosphorus, estimated glomerular filtration rate, and total parathyroid hormone before potassium lowering treatments between the 2 groups were compared. Multiple logistic regression analysis was used to identify the risk factors for hypocalcemia in 3-5 stages of CKD patients with hyperkalemia and non-dialysis after potassium lowering therapy. Results A total of 260 patients were entered, including 58 with blood calcium lower than 2.12 mmol/L, and incidence of hypocalcemia was 22.3%. The differences in the baseline corrected calcium, blood phosphorus, carbon dioxide binding capacity, estimated glomerular filtration rate, and total parathyroid hormone between the hypocalcemia group and the non-hypocalcemia group were statistically significant (P<0.05). The factors with P<0.1, including primary disease, baseline corrected calcium, blood phosphorus, carbon dioxide binding capacity, estimated glomerular filtration rate, and total parathyroid hormone, were included in the multivariate logistic regression analysis. The results showed that the probability of hypocalcemia at baseline corrected calcium levels of 2.12-2.21, 2.22-2.31, and 2.32-2.41 mmol/L was 49.306 times, 13.651 times, and 13.342 times that of at ≥2.42 mmol/L, respectively. Low carbon dioxide binding capacity (odds ratio=0.909, 95% confidence interval: 0.836-0.987) was also a risk factor of hypocalcemia in 3-5 stages CKD patients with hyperkalemia and non-dialysis after potassium lowering therapy. Conclusions Three to five stages of CKD patients with hyperkalemia and non- dialysis are prone to hypocalcemia after potassium lowering therapy. The low levels of baseline corrected calcium and carbon dioxide binding may be closely related to the occurrence of hypocalcemia in 3-5 stages of CKD patients with hyperkalemia and non-dialysis after potassium lowering therapy.

    Sodium-glucose transporter 2 inhibitors (SGLT2i) are currently widely used as a class of hypoglycemic drugs. Due to their unique hypoglycemic mechanism and significant cardio-renal protective effect, SGLT2i have become one of the core drugs in the treatment of type 2 diabetes mellitus. However, in recent years, it has been found that SGLT2i can lead to increased serum creatinine and urea nitrogen in some patients, and the risk of kidney injury has gradually attracted clinical attention. How to effectively prevent and supervise the potential renal injury risk while giving full play to its therapeutic advantages has become an important topic in current clinical practice and drug safety management. Multi-dimensional prevention and supervision strategies should be adopted in clinical practice such as identifying high-risk populations based on the latest evidence, strictly screening patients, dynamically monitoring renal function, optimizing combination medication regimens, and achieving risk warning using biomarkers and artificial intelligence tools.

    Objective To analyze the characteristics of Fournier gangrene (FG) induced by sodium-glucose cotransporter 2 inhibitors (SGLT2i), and provide reference for clinical safe drug use. Methods CNKI, Wanfang Med Online, VIP, PubMed, Web of Science and other databases (up to January 2024) were retrieved and clinical data on patients with FG associated with the 5 kinds of SGLT2i currently used in clinical practice in China were collected and descriptively analyzed, including gender, age, comorbidities, concomitant medications, onset time and clinical manifestations of SGLT2i-related FG, laboratory and imaging examination results, treatment and outcomes, etc. Results A total of 15 documents were included in the analysis, involving 15 patients, with 12 males and 3 females. The age of these patients ranged from 34 to 72 years, with 11 cases being over 50 years. Dapagliflozin was used in 7 cases, empagliflozin in 6 cases, canagliflozin in 2 cases, and no related reports on ertugliflozin and henagliflozin were collected. The main clinical manifestations of the 15 patients were redness, swelling, pain, abscess or purulent discharge in perineum, scrotum and perianal, etc. The time from application of SGLT2i to onset of FG ranged from 1 month to 6 years. Wound secretion bacterial culture was performed in 10 patients, and the results were all positive, including 9 cases of bacterial infection and 1 case of mixed infection of bacteria and fungi. All 13 patients who underwent imaging examinations had imaging manifestations related to FG. SGLT2i were discontinued in all patients. After treatments with broad-spectrum antibiotics and surgery, 14 cases were improved and 1 case was cured. Conclusions SGLT2i has the risk of causing FG, which is more common in males. The clinical use of SGLT2i should be monitored closely. Secretion culture and imaging examination are helpful for the diagnosis of FG. The patient′s prognosis is good after discontinuation of medication, symptomatic treatment, and surgery.

    Objective To mine the adverse event (AE) risk signals of semaglutide and liraglutide in weight management populations, and provide references for the safe use of these drugs in relevant patients. Methods The reporting odds ratio (ROR) method, proportional reporting ratio (PRR) method, Bayesian confidence propagation neural network (BCPNN) method, and empirical Bayesian geometric mean (EBGM) method were used to mine the AE risk signals of semaglutide and liraglutide in weight management populations from the US Food and Drug Administration Adverse Event Reporting System (FAERS) database from the 1st quarter of 2010 to the 4th quarter of 2023. Adverse events that met the criteria of all 4 mining methods were considered as risk signals. The adverse events were classified and statistically analyzed using the system organ class (SOC) and preferred term (PT) of the 26.1 version of the Medical Dictionary for Regulatory Activities 26.1 version, and the identified risk signals were analyzed. Results During the set period, 2 292 AE reports for semaglutide for weight management (excluding diabetes) and 2 973 for liraglutide were retrieved. The semaglutide-related AE reports involved 83 PTs, among which 57 were already recorded in the instructions and 26 were not. Among the 26 PTs not recorded in the labels, the top 5 PTs in terms of AE report numbers were increased appetite, hunger, panic attack, binge eating, and feeling cold; the top 5 PTs in terms of ROR values were lack of satiety, hunger-induced ketoacidosis, myoglobinuria, binge eating, and bulimia. The liraglutide-related AE reports involved 74 PTs, among which 60 were already recorded in the instructions and 14 were not. Among the 14 PTs not recorded in the labels, the top 5 PTs in terms of AE report numbers were weight gain, increased appetite, binge eating, weight fluctuation, and pancreatic cyst; the top 5 PTs in terms of ROR values were lack of satiety, binge eating, hepatic adenoma, increased appetite, and pancreatic cyst. Three PTs of severe AEs that were not recorded in the labels for semaglutide were identified, namely, olfactory abnormality, ketoacidosis, and panic attack. One PT of severe AE that was not recorded in the labels for liraglutide was identified, namely, metastatic pancreatic cancer. Conclusion The AE risk signals of semaglutide and liraglutide in weight management include AEs not recorded in the labels, and some are even serious AEs, which need to be identified and prevented in clinical practice.

    Objective To understand the influencing factors for cardio-cerebrovascular complications in patients with T2DM and construct a nomogram risk prediction. Methods The study design was a prospective observational study, and the subjects were selected from hospitalized patients with T2DM admitted to Huangshan City People′s Hospital from May 2022 to April 2023. Data on patients' gender, age, body mass index, alcohol consumption, smoking status, family history of cardio-cerebrovascular diseases, insulin use, duration of diabetes, blood pressure, and routine laboratory test results were collected using the hospital electronic medical record system. At discharge, patients were assessed using the T2DM-Specific Medication Belief Scale (total score range: 10-50), Medication Literacy Assessment Scale (total score range: 0-7), and Morisky Medication Adherence Scale (total score range: 0-8). Patients were followed up by telephone for 6 months after discharge and divided into 2 groups based on the occurrence of cardio-cerebrovascular complications. Logistic regression analysis was performed using SPSS 26.0 software to identify influencing factors for cardio-cerebrovascular complications in T2DM patients. A nomogram prediction model was constructed using R 4.1.0 software, and internal validation of the model was conducted using the Bootstrap method. Results A total of 294 T2DM patients were included in the analysis. The medication belief score was (32.6±5.6) score, the medication literacy score was (4.2±0.5) score, and the medication adherence score was (6.1±0.8) score. During the 6 month follow-up, a total of 43 patients (14.6%) experienced cardio- cerebrovascular complications, including of coronary heart disease (23 cases), heart failure (12 cases), and stroke (8 cases). Compared to patients without cardio-cerebrovascular complications, patients with complications had higher body mass index, glycosylated hemoglobin A1c (HbA1c), D-dimer, and uric acid levels, as well as lower medi- cation belief scores, medication literacy scores, and medication adherence scores (all P<0.05). Binary logistic regression analysis showed that HbA1c, D-dimer, uric acid, medication belief, medication literacy, and medication adherence were influencing factors for cardio-cerebrovascular complications in T2DM patients. Accordingly, a nomogram prediction model was established. Internal validation results of the model showed that the concordance index was 0.958, the area under the receiver operating characteristic curve was 0.824, and the calibration curve was close to the ideal curve. Conclusions The current status of medication belief, medication literacy, and medication adherence in T2DM patients was not ideal. High levels of HbA1c, D-dimer, and uric acid, as well as poor medication belief, medication literacy, and medication adherence were risk factors for cardio-cerebrovascular complications in T2DM patients. The nomogram model, which integrated multiple influencing factors, had high value in predicting the risks.

    Intravitreal injection (IVI) is an administration technique that uses a syringe to deliver drugs into the vitreous cavity. Currently, multiple IVI drugs have been successively approved for the treatment of various fundus diseases, including antivascular endothelial growth factor drugs, intravitreal sustained- release glucocorticoid drugs, and so on. Meanwhile, there are many injection drugs off label used by IVI. At present, there is a lack of pharmaceutical care guidance documents for the clinical application of IVI drugs. To promote the development of pharmaceutical care for IVI drugs, Ophthalmic Pharmacy Professional Committee of Peking Safety Medicine Foundation, Medicine Therapy Management Working Committee of Chinese Pharmacists Association, and Clinical Pharmacy Branch of China International Exchange and Promotive Association for Medical and Health Care organized experts to formulate this consensus based on clinical practice experience and with reference to relevant domestic and foreign research data, guidelines, and literature. This consensus combs the characteristics of clinical application of IVI drugs, relevant pharmaceutical services before, during and after injection, and forms 26 recommendations for 5 clinical issues, which can be used by medical institutions at all levels to carry out pharmaceutical services of IVI drugs. The users are medical staff in medical institutions at all levels (including pharmacists, physicians, nurses, and other relevant staff), and the target population for application is mainly patients using IVI drugs.

    Drug-induced neurological disorders (DINDs) refer to the central or peripheral nervous system disease caused by drugs. DINDs account for a large proportion of adverse drug reactions/events in China, and its onset is complex to some extent. Common DINDs include epilepsy, movement disorders, stroke, peripheral neuropathy, spinal cord injury, cognitive impairment and so on. Usually, DINDs have characters of gradual development and late-onset reactions, and it is difficult to associate their clinical manifestations with drugs, leading to misdiagnosis and poor prognosis in clinic. To reduce the neurotoxicity of drugs, multidisciplinary cooperation should be strengthened, and individualized treatment plans for high-risk people and closer monitoring should be implemented for timely identification and diagnose. At the same time, relevant researches on DINDs should be strengthened in the clinic to cope with the complexity and long-term prognosis challenges of the diseases.

    Objective Based on the adverse drug event active surveillance and assessment system-Ⅱ (ADE-ASAS-Ⅱ) and the information of inpatients in the hospital information system (HIS), the automatic monitoring module of movement disorders was constructed and its application effect in the real- world study of drug-induced movement disorders (DIMDs) was explored. Methods Literature reviews, case reports, spontaneous reports and medical records were collected, the keyword set was screened based on ADE-ASAS-Ⅱ system and text classification technology, and an automatic monitoring module was constructed. The information of hospitalized patients in Chinese PLA General Hospital (our hospital) was selected from October 10 to 16, 2022. The results of manual evaluation and the system alarm by the automatic monitoring module were compared, and the performance of the automatic monitoring module was evaluated and optimized through repeated machine learning. The medical record information of hospitalized patients who used sodium valproate throughout the year in our hospital in 2022 were collected, and the occurrence of movement disorders related to sodium valproate was analyzed using the automatic monitoring module. Results A total of 4 918 hospitalized patients (146 with movement disorders) were collected, and the final setting conditions of the automatic monitoring module were determined, including inclusion criteria (43 text keywords, 3 diagnosis) and exclusion criteria (11 text and 20 document titles were omitted). Among the 1 138 hospitalized patients using sodium valproate in 2022, the incidence of DIMDs with tic and tremor as main clinical manifestations detected by automatic monitoring module was 1.67% (19/1 138). Conclusion The automatic monitoring module of druginduced movement disorders based on machine learning and manual evaluation can be applied to explore the occurrence characteristics of DIMDs in the real world, and provide information for pharmacovigilance in clinic.

    Objective To understand the clinical characteristics of myelopathy induced by intrathecal chemotherapy of methotrexate (MTX) and/or cytarabine (Ara-C). Methods Relevant databases at home and abroad (up to February 18, 2024) were searched and case reports of myelopathy induced by intrathecal chemotherapy of MTX and/or Ara-C were collected. The patients′ general situation (gender, age, primary disease, etc.), use of MTX and/or Ara-C, previous radiotherapy, and occurrence time, clinical manifestations, spinal magnetic resonance imaging (MRI) results, cerebrospinal fluid test results, treatments and outcomes of myelopathy were extracted and analyzed descriptively and statistically. Results A total of 75 articles were enrolled, involving 104 patients, with 62 males, 35 females, and 7 unknown genders. Their ages ranged from 1 to 74 years, with a median age of 26 years. The primary diseases included hematological malignancy in 101 cases, and other solid tumors in 3 cases. Before the occurrence of myelopathy, 42 cases had central nervous system tumor infiltration. Seventy-three patients received intrathecal injection of MTX combined with Ara-C, 21 patients received single MTX therapy, 10 patients received single Ara-C therapy. The number of intrathecal injections ranged from 1 to 62, with a median of 5 injections. Twenty-nine patients had received radiotherapy before. When myelopathy occurred, the cumulative dose of MTX was 7.5-480.0 mg, with a median cumulative dose of 60.0 mg; the cumulative dose of Ara-C was 15 1 599 mg, with a median cumulative dose of 280 mg. The onset time of myelopathy was from immediately to 365 days after the last intrathecal injection, with a median time of 2 days. The main clinical manifestations were weakness of both lower limbs, urinary and fecal incontinence or retention, paresthesia, and paraplegia, etc. Fifty-three patients had spinal abnormality in MRI examination, 32 had abnormal cerebrospinal fluid protein quantity, intrathecal basic protein, or homocysteine. After the diagnosis of myelopathy, 86 patients were treated with drugs, radiotherapy, plasma exchange, and cerebrospinal fluid exchange, and 18 patients had no record of treatment situation. Therapeutic agents included glucocorticoids, B vitamins, folic acid, immunoglobulin, leucovorin, S-adenosylmethionine, and dextromethorphan. Of the 104 patients, 20 achieved complete remission, with a median remission time of 30 hours; 25 experienced partial remission, with a median duration of 120 days; 32 showed no significant improvement; 26 died; one patient′s prognosis and outcome were unknown. Conclusions The median occurrence time of myelopathy induced by intrathecal injection of MTX and/or Ara-C is 2 days. The main clinical manifestations are bilateral lower extremity weakness, urinary and bowel incontinence or retention, paresthesia, and paraplegia, etc. Abnormal spinal in MRI examination, quantitative cerebrospinal fluid protein, intrathecal basic protein occurred in some patients. Intrathecal injection should be stopped immediately after diagnosis of myelopathy, and the treatments such as drug and cerebrospinal fluid replacement should be given. The clinical outcome of myelopathy induced by intrathecal MTX and/or Ara-C was poor.

    Objective To understand the clinical characteristics of hypophysitis due to nivolumab and provide reference for the safe use of nivolumab in clinic. Methods Relevant databases at home and abroad (up to May 31, 2024) were searched and case reports of hypophysitis caused by nivolumab were collected. Relevant information of patients (gender, age, primary disease), single and combined use of nivo- lumab, occurrence of hypophysitis, causality evaluation, intervention measures and outcomes were extracted and analyzed descriptively and statistically. Results A total of 56 case reports, 53 in English and 3 in Chinese, were enrolled in the analysis, involving 59 patients, with 40 males and 19 females. Their ages ranged from 26 to 84 years, with an average age of 61 years. The primary diseases were malignant melanoma in 20 cases, renal cell carcinoma in 19 cases, lung cancer in 11 cases, glossopharyngeal cancer in 4 cases, esophageal cancer in 2 cases, and gastric cancer, colon cancer and pleural mesothelioma in 1 case each. Among the 59 patients, 33 were treated with nivolumab monotherapy, 24 with nivolumab and ipilimumab, 1 with nivolumab and anlotinib and 1 with nivolumab and platinum. The average time of hypophysitis caused by nivolumab alone was 25.6 weeks after treatment, and that caused by the combination therapy was 9.9 weeks after treatment. The main clinical manifestations of hypophysitis caused by nivolumab were fatigue, anorexia, headache, and nausea. Among the 59 patients, 56 patients discontinued nivolumab and received glucocorticoid, 20 of whom resumed nivolumab treatment after improvement of clinical symptoms; 3 patients′ situation was not described clearly. The outcomes of the 59 patients were as follows. Four were recovered, 46 were relieved, 2 patients′ pituitary function was not recovered, 4 died, 1 developed secondary autoimmune vasculitis, 1 developed secondary autoimmune hepatitis, and it was unknown in one patient. Conclusions The average occurrence time of hypophysitis caused by nivolumab monotherapy is longer than that caused by combination therapy. The main clinical manifestations are fatigue, anorexia, headache, etc. After timely discontinuation of medication and symptomatic treatments with glucocorticoid, most patients have a good prognosis, but it can lead to death in severe cases.

    With the aging of the population and the increasing number of patients with throm- boembolic diseases, oral anticoagulants are more and more widely used. Anticoagulant-related nephropathy (ARN) is a significant adverse reaction in the treatment with oral anticoagulants, generally considered to be a form of acute kidney injury caused by excessive anticoagulation. The mechanisms involved may include glomerular hemorrhage, obstruction of renal tubules by red cell casts, and damage to tubular epithelial cells. Abnormalities in coagulation function and renal function are the main risk factors for ARN; older age, diabetes mellitus, and cardiovascular diseases such as hypertension and heart failure also increase the  risk of ARN occurrence. ARN should be managed based on individual patient characteristics. Benefits and risks of treatment should be carefully considered when choosing oral anticoagulants; renal function should be closely monitored during treatments to detect potential risks early. In case of ARN, it is advised to promptly adjust the anticoagulant therapy and provide symptomatic supportive treatments. In severe cases, treatments with methylprednisolone combined with hemodialysis can be employed.

    Objective To explore the effect of concomitant amiodarone on the bleeding risk in atrial fibrillation patients treated with dabigatran etexilate. Methods This study was a retrospective cohort study. The clinical data of hospitalized patients with atrial fibrillation who took dabigatran etexilate in Tongji Hospital, Tongji Medical College, Huazhong University of Science & Technology from July 1, 2022 to June 30, 2023 were collected. Patients were divided into concomitant amiodarone group and non concomitant amiodarone group according to whether they were treated with oral amiodarone. Propensity score matching (PSM) was performed at a 1∶1 ratio in patients between the 2 groups according to patient's gender, age, main basic diseases and the number of basic diseases, baseline liver and kidney function, dosage of dabigatran etexilate, etc. The incidence of bleeding events was compared between the 2 groups. Results A total of 878 patients were included in the study, including 568 males (64.7%) and 310 females (35.3%), with a age of 67 (59, 74) years. There were 252 patients (28.7%) in the concomitant amiodarone group and 626 patients (71.3%) in the non concomitant amiodarone group. Within 3 months of follow-up, the incidence of bleeding events in patients of concomitant and non concomitant amiodarone groups were 19.0% (48/252) and 21.2% (133/626), respectively, which were 19.0% (48/252) and 16.7% (40/239) after PSM, respectively, with no significant difference (all P>0.05). The main type of bleeding in patients of both groups was mild bleeding events [62.5% (30/48) vs. 67.5% (27/40)], and bleeding was more common in the gums, skin, and nose. There was no statistically significant difference in incidence of the bleeding types and bleeding sites of patients between the 2 groups (all P>0.05). Conclusions Compared with patients with atrial fibrillation when treated with dabigatran etexilate and without concomitant amiodarone, the bleeding risk of patients with amiodarone did not significantly increased in the short term. The bleeding events during treatment of dabigatran etexilate were mainly mild bleeding, but clinical vigilance was still necessary.

    Objective To mine the risk signal of acute kidney injury (AKI) induced by different oral anticoagulant drugs (OACs) in various populations and provide a reference for clinical use of OACs.  Methods Reports of AKI induced by OACs and non-OACs in the US Food and Drug Administration Adverse Event Reporting System database from the 1st quarter of 2004 to the 3rd quarter of 2023 were collected. The relationship between the drugs mentioned above and the AKI in patients were analyzed by methods of reporting odds ratio (ROR) and Bayesian confidence propagation neural network (BCPNN). When the number of reports of the target adverse event (AE) for the target drug was ≥3, and the lower limit of the 95% confidence interval (CI) of ROR was >1 or the lower limit of the 95%CI of the information component (IC025) was >0, it indicated a statistically significant association between the target drug and the target AE. Results A total of 12 402 AKI reports related to OACs were collected, including 1 313 for warfarin, 3 086 for dabigatran, 4 730 for rivaroxaban, 2 918 for apixaban, and 365 for edoxaban; 454 378 AKI reports were related to non-OACs. The overall analysis of OACs showed an ROR (lower limit of 95%CI) of 1.791 (1.759) and an IC (IC025) of 0.813 (0.787) for AKI caused by OACs. Analysis of individual OACs showed that warfarin, dabigatran, rivaroxaban, apixaban, and edoxaban all posed risks for AKI, with ROR (lower limit of 95%CI) of 1.220(1.156), 2.386(2.302), 2.044(1.986), 1.375(1.326), 3.003(2.706), respectively, and IC (IC025) of 0.284(0.204), 1.231(1.178), 1.010(0.968), 0.452(0.399), 1.560(1.407), respectively. Edoxaban had the highest ROR and IC values, while warfarin had the lowest. Subgroup analysis showed that in the <18 years subgroup, neither warfarin nor rivaroxaban showed a risk of AKI; the ROR method did not show dabigatran to have a risk of AKI, but the BCPNN method did. In the 18-45 years subgroup, both methods showed that apixaban did not have a risk of AKI, while all other OACs did. In the 45-64 years subgroup, all OACs showed a risk of AKI. In the ≥65 years subgroup, warfarin and apixaban posed risks for AKI. Gender subgroup analysis showed that both methods indicated a risk of AKI with warfarin in males; all OACs showed a risk of AKI in females. Conclusions OAC has a statistically significant risk of AKI, among which edoxaban has the highest risk intensity and warfarin has the lowest. Different OACs have different risks of AKI in patients with different ages.

    Objective To explore the risk factors of severe medication errors (ME) of tranexamic acid injection (TXAI), and put forward prevention suggestions. Methods TXAI-related ME reports in the National Monitoring Network for Clinical Safe Medication (Monitoring Network) and medical literature databases at home and abroad were searched, and case reports of TXAI-related ME were collected; China Judgements Online and PKULAW database were searched, and TXAI-related judicial cases judged to be responsible by the hospital were collected. The retrieval time of all data was up to May 1, 2024. The severity grade, occurrence link and place, and the trigger person of TXAI-related ME reported in the Monitoring Network were retrospectively analyzed. The year of report, country of occurrence, clinical application, error content, and occurrence place of the collected severe ME cases, and the clinical characteristics of patient injury, patient outcome and the ME grading were retrospectively analyzed. Results From September 22, 2012 to May 1, 2024, the Monitoring Network received a total of 138 TXAI-related ME reports, and there was an increasing trend in the number of reports year by year. Among 138 cases of ME, 79 (57.3%) occurred in the drug dispensing and distribution link; 58 (42.0%) occurred in the prescription/doctor′s order prescribing and delivery link and mainly involved easily mixed drugs and drug overdose, of which 1 (1.7%) was a severe ME (grade E); 1 (0.7%) occurred in the drug administration link, and iodohexol was mistakenly injected as TXAI into the patient′s joint cavity. A total of 29 severe ME reports related to TXAI were collected. Of them, 24 (82.8%) were due to incorrect administration routes (22 were confused with anesthetics and 2 were confused with injection catheters, all resulting in incorrect intrathecal injections) and 5 (17.2%) were due to prescription errors (3 were overdosed, 1 was used for high-risk thrombosis patient, and 1 was treated with combination use of hemocoagulase for high-risk thrombosis patient); 23 (79.3%) occurred in the operating rooms, and 6 (20.7%) occurred in the wards. The 24 patients involved in incorrect intrathecal injections of TXAI mainly developed severe pain, neurotoxicity (status epilepticus) and/or cardiotoxicity (arrhythmia and ventricular fibrillation), of which 11 (45.8%) died and 2 (8.3%) had sequelae of limb muscle weakness. Among the 5 patients with prescription errors, 4 developed severe thrombotic disease, resulting in 2 deaths and 2 cerebrovascular-related sequelae, and the other one developed palpitation, shortness of breath, nausea and vomiting. Among the 29-severe ME cases, 2 (6.9%) were grade E, 3 (10.3%) were grade F, 4 (13.8%) were grade G, 7 (24.2%) were grade H, and 13 (44.8%) were grade I. Conclusions TXAI-related ME mainly involved easily mixed drugs and prescription errors. The severe ME main occurred in the operating room and mainly due to incorrect intrathecal injection, leading to fatal neurological and cardiac toxicity in patients.

    Intravenous infusion has played an important role in emergency treatments in China, but there is also the phenomenon that emergency infusion is overused. The high burden of emergency infusion may cause more medication safety problems, such as adverse drug reactions, medication errors, drug interactions, and so on. The risks in emergency infusion should be paid high attention to. We should actively construct a comprehensive management model for the prevention and control of emergency infusion safety risks by strengthening multidisciplinary cooperation, avoid unnecessary intravenous infusion, and develop diagnostic criteria and treatment guidelines for adverse events in intravenous infusion, so as to better ensure the medication safety in emergency patients treated with intravenous infusion.

    Objective To investigate the clinical characteristics and interventions associated with drug-induced anaphylaxis in the emergency infusion room. Methods Bases on the adverse drug reaction database from the emergency medicine center of the First Affiliated Hospital of Nanjing Medical University, clinical data of patients who experienced drug-induced anaphylaxis in the emergency infusion room between November 2019 and November 2023 were collected, including gender, age, history of previous adverse drug reactions, allergy history, Charlson comorbidity index, medication details, information related to drug-induced anaphylaxis (onset time, clinical manifestations), interventions, outcomes, and follow-up. The clinical characteristics and interventions in these patients were analyzed. Results During the study period, a total of 398 772 patients in the emergency infusion room in our hospital received intravenous infusion of drugs. Of them, 625 cases developed adverse drug reactions (ADRs) and 75 cases developed drug- induced anaphylaxis, accounting for 0.02% (75/398 772) of the total infusion patients and 12.0% (75/625) of all ADR cases. Of the 75 patients with anaphylaxis, 30 cases (40%) were classified as grade Ⅱ, and 45 cases (60%) as grade Ⅲ, with no grade Ⅳ cases. The most common drugs involved in 75 cases of anaphylaxis were anti-infective drugs (41 cases, 54.7%). Drug-induced anaphylaxis exhibited diverse clinical manifestations, with cardiovascular symptoms being the most common, primarily varying degrees of transient hypotension (67 cases, 89.3%), followed by systemic and neurological symptoms, including profuse sweating (31 cases, 41.3%) and dizziness (28 cases, 37.3%). All 75 patients with anaphylaxis were treated with measures such as discontinuation of medication, replacement of infusion sets, rapid assessment of circulation and respiration, and monitoring of vital signs, of which 65 (86.7%) received rapid intravenous infusion for volume expansion, 6 (8.0%) received intravenous injection of glucocorticoids, 3 (4.0%) received intramuscular injection of 0.5 mg epinephrine, and 2 (2.7%) received antihistamines. All 75 patients showed improvement in symptoms, and no sequelae or deaths were found. Conclusions In the emergency infusion room, the severity of anaphylaxis is mainly grade Ⅱ and Ⅲ with a good prognosis after timely intervention. The treatment measures mainly focus on rapid intravenous infusion for volume expansion, and the use of epinephrine is relatively low.

    Objective To explore the occurrence and clinical characteristics of infusion-related reactions (IRRs) caused by lecanemab in Chinese patients with Alzheimer disease, and summarize the nursing management experience of IRRs. Methods This study was a single center retrospective study and the subjects were Alzheimer′s disease patients who received lecanemab (10 mg/kg, once every 2 weeks) in the Department of Neurology, Xuanwu Hospital, Capital Medical University from June 26 to August 18, 2024. The occurrence, clinical characteristics, severity, and outcome of IRRs that occurred during the treatment of lecanemab in these patients were descriptively analyzed. Results A total of 45 patients were included in the study, including 15 males (33.3%) and 30 females (66.7%); the age ranged from 52 to 82 years, with a median age of 62 years. Among the 45 patients, 15 (33.3%) developed IRRs, including 6 males and 9 females, and 2 of them had a previous history of allergy. In the 15 patients, there were 3, 8, 1 and 3 patients with 1, 2, 3 and 4 treatment cycles, respectively; 13 patients were pretreated with diphenhyd-ramine 30 minutes before lecanemab treatment; 14 patients had IRRs in the first cycle of lecanemab treatment, and 1 in the second cycle; IRRs occurred within 5 hours after finishing the intravenous infusion of lecanemab in 13 patients and on the second day after the administration in 2 patients. The main manifestations of IRRs were fever and chills; some patients had headache, nausea, and vomiting symptoms, and only 1 patient developed rash and itching. After symptomatic treatments, these symptoms in the 13 patients were relieved soon, and IRRs did not recur after the continued treatment of lecanemab according to the regime. The severity of IRRs was grade 1, 2, and 3 in 5, 9, and 1 patient, respectively. The incidence of severe IRRs was 2.2% (1/45). Conclusions IRRs are common adverse reactions of lecanemab, mainly characterized by fever and chills, with mild severity. Generally, lecanemab-related IRRs occurs after the first administration, and may not occur again in the continued treatments. Vital signs should be routinely monitored in lecanemab treatment. Once IRRs occur, timely treatments should be given according to the severity, and the prognosis is usually good.

    Anticancer drugs are important causes of kidney injury in cancer patients. Once kidney injury occurs, it will affect anticancer therapy and patient prognosis. Thus, the Japanese Society of Nephro- logy, Japan Society of Clinical Oncology, Japanese Society of Medical Oncology, and Japanese Society of Nephrology and Pharmacotherapy have jointly formulated the Clinical Practice Guidelines for Management of Kidney Injury During Anticancer Drug Therapy 2022 and made a particular discussion on the prevention and management of anticancer drug-induced kidney injury. This article focuses on interpreting the management of kidney injury related to cytotoxic anticancer drugs, targeted therapies, and immune checkpoint inhibi-tors to more effectively guide clinical practice.

    The safety of traditional Chinese Medicine (TCM) has garnered widespread attention and has become a major obstacle to its further development and internationalization. The complexity of TCM and the unpredictability of its interactions with the human body pose significant challenges to safety research. The causes of TCM safety issues are multifaceted, including intrinsic and extrinsic toxicity, confusion of herbal sources and misuse in clinical practice, inadequate patient awareness of safe medication use, and insufficient regulatory oversight of TCM quality and safety. To strengthen the risk managements, it is essential to employ scientific technologies to investigate the fundamental nature of TCM safety, leverage artificial intelligence for big data analysis and early risk warning, promote the scientific concept of safe TCM use, and establish a comprehensive lifecycle pharmacovigilance system for TCM. These will facilitate TCM safety research in China, ensure patient medication safety, and promote the healthy and sustainable development of the TCM industry and its internationalization.
