Objective To analyze the adverse reaction reports （ADRs） of drug-induced liver injury in recent ten years, explore the characteristics and related rules of drug-induced liver injury, and provide reference for clinical safe drug use. Methods ADRs in our hospital from 2011 to 2021 which belonged to drug-induced liver injuries were collected, and Pareto analysis was carried on. Results In 259 ADR reports, the most common type of drug-induced liver injury was hepatocellular injury （37.84%）. The age of drug-induced liver injury was mainly over 46 years, totaling 195 （75.28%）. Drugs were mainly distributed in cardiovascular system medicine （44.02%）, anti-infective medicine （23.94%）and anti-tumor medicine （11.58%）. Among the cardiovascular drugs, atorvastatin calcium 40mg and over 40mg were the highest proportion, with 53 cases （46.49%）. The main anti-infectious drugs were cephalosporins （29.03%）, carbapenem （19.35%）， antifungal （17.74%）and quinolones （11.29%）. Adverse reactions occurred within 6 days （69.88%）, the duration of adverse reactions was 1-2 weeks （31.66%）, and most patients were improved （47.88%） or cured （37.07%）. Conclusion For middle-aged and elderly patients, when the application of cardiovascular system drugs, anti-infective drugs or anti-tumor drugs, it is necessary to monitor the liver function changes of patients for at least 6 days. If there are abnormalities, the drugs should be stopped or given treatment in time, to avoid the progress of drug-induced liver injury.

Objective:To analyze the factors influencing the theoretical score of graduation examination of standardized residency training in a class-A tertiary general hospital in Shanghai from 2018 to 2021, and establish prediction models, and to provide a reference for further improving the quality of residency training.Methods:We collected the data of 556 residents who participated in the residency training graduation examination at the hospital from 2018 to 2021. Binary regression and logistic regression analyses were used to determine the association of residents' basic information, their routine assessment results at the bases, and the base performance assessment score (indicating the bases' training quality) with theoretical graduation examination results; and prediction models for the theoretical graduation examination score were established, using binary regression and logistic regression methods to construct model datasets. SPSS 26.0 was used for statistical analysis.Results:From 2018 to 2021, a total of 556 people participated in the residency training graduation examination at the hospital. The first-time pass rate of the first station theoretical examination station was 97.48% (542/556). Trainees graduating from double first-class schools had the highest first-time pass rate of 98.09% (359/366); doctoral students had the highest first-time pass rate of 98.59% (140/142); and residents of the two-year training program had the highest first-time pass rate of 98.34% (297/302). According to the binary regression analysis of categorical variables such as residents' basic information, the base level was associated with whether residents passed the theoretical examination ( P<0.05). According to the logistic regression analysis of residents' routine assessment scores and the base performance assessment score, the annual theoretical assessment score, the first-time theoretical score of the national medical licensing examination, the annual professional performance test score, and the base performance assessment score were key factors affecting the theoretical graduation examination score ( P<0.05). In the regression analysis associated with the theoretical graduation examination score, the annual professional performance test score showed the highest regression coefficient and the highest variance inflation factor, indicating strong multicollinearity. Therefore, the annual professional performance test score was important in predicting the theoretical score of the graduation examination. Conclusions:This study used binary regression and logistic regression models to analyze the possible factors affecting the theoretical graduation examination score and the degree of association, and also established two prediction models of the theoretical graduation examination score to predict trainees at risk. Through implementing the concept of hierarchical progression, adding personalized tutoring, realizing information management for residency training, and providing intelligent early intervention, the pass rate of residency training graduation examination is expected to be further improved, ultimately achieving the purpose of improving the quality of residency training.

Objective To investigate the effect of matrine on apoptosis and oxidative damage of PC12 cells induced byβ-amyloid protein(Aβ)25-35 in Alzheimer disease and to analyze the mechanism of its interaction with the AMP-activated protein kinase(AMPK)/silenced information regulator(SIRT1)pathway.Methods The effect of matrine on the growth of PC12 cells was determined using MTT.Matrine concentrations of 0.5,1.0,and 1.5 mmol/L were selected for the experiment.PC12 cells were divided into the Con group(blank culture cells),the Aβ25-35 group(20 μmol/L Aβ25-35 treated cells),the Aβ25-35+Matrine-L group,the Aβ25-35+Matrine-M group,and the Aβ25-35+Matrine-H group(20μmol/L Aβ25-35 were treated with 0.5 mmol/L,1.0 mmol/L,and 2.0 mmol/L matrine).Cell proliferation was detected using MTT.The detection of superoxide dismutase(SOD),glutathione peroxidase(GSH-Px),interleukin-6(IL-6),interleukin-1β(IL-1β),tumor necrosis factor-α(TNF-α)using enzyme-linked immunosorbent assay,expression of B-cell lymphoma/leukemia-2(Bcl-2),Bcl-2 associated X protein(Bax),cleaved caspase-3 containing cysteine,and AMPK/SIRT1 pathway-associated proteins were detected using Western blotting.Results Compared to the Con group,OD value,Bcl-2 protein expression,SOD,and GSH-Px activity decreased at 24 h and 48 h;the apoptosis rate,Bax,cleaved caspase-3 protein expression,ROS content,IL-6,IL-1β,and TNF-α expression increased,and P-AMPK and SIRT1 protein expression were up-regulated in the Aβ25-35 group(all P<0.05).Compared to the Aβ25-35 group,OD value,Bcl-2 protein expression,SOD,and GSH-Px activities in the Aβ25-35+Matrine-L group,the Aβ25-35+Matrine-M group,and the Aβ25-35+Matrine-H group increased at 24 h and 48 h.Apoptosis rate,Bax,cleaved caspase-3 protein expression,and ROS content decreased.IL-6,IL-1β,and TNF-αexpression decreased,and p-AMPK,and SIRT1 protein expression were down-regulated(all P<0.05).Conclusion Matrine may reduce the apoptosis and oxidative damage of PC12 cells induced by Aβ25-35 by inhibiting the AMPK/SIRT1 pathway.

Objective To systematically review the efficacy of multiple doses and single dose of perioperative dexamethasone on pain and recovery after total knee arthroplasty(TKA).Methods PubMed,Embase,Cochrane Library,Web of Science,CNKI,WanFang Data,SinoMed and VIP databases were electronically searched to collect randomized controlled trials(RCTs)on multiple doses and single dose of dexamethasone during perioperative period of TKA from inception of the databases to January 4,2024.Two reviewers independently screened the literature,extracted data and assessed the risk of bias of the included studies.Meta-analysis was performed by using RevMan 5.4 software.Results A total of 6 studies involving 674 patients were included,336 patients in single dose dexamethasone group and 338 patients in multiple dose dexamethasone group.The results of Meta-analysis showed that compared with single dose of dexamethasone,multiple doses of perioperative dexamethasone could significantly decrease the pain scores at rest at 48 h after TKA(SMD=-0.68,95%CI-1.05 to-0.30,P﹤0.001),the pain scores with movement at postoperative 48 h(SMD=-0.86,95%CI-1.37 to-0.34,P=0.001),C-reactive protein(CRP)levels at postoperative 48 h(MD=-4.43,95%CI-6.70 to-2.16,P﹤0.001)and CRP levels at postoperative 72 h(MD=-3.60,95%CI-5.53 to-1.67,P﹤0.001).There was no statistically significant difference between the two groups regarding pain scores at rest at postoperative 24 h and 72 h,pain scores with movement at postoperative 24 h and 72 h,incidence of postoperative nausea and vomiting(PONV),CRP levels at postoperative 24 h,length of hospital stay,and incidence of adverse drug reactions(P>0.05).The results of 5 studies showed that multiple doses of dexamethasone did not increase the dosage or patient proportion of remedial analgesics.Conclusion Current evidence shows that compared with single dose of dexamethasone,multiple doses of perioperative dexamethasone can significantly reduce pain scores at postoperative 48 h,CRP levels at postoperative 48 and 72 h after TKA,but it does not significantly reduce the incidence of PONV,hospital stay,or increase the risk of adverse drug reactions.

Objective To observe the value of parallel acquisition technique(PAT)combined with deep learning reconstruction(DLR)for shoulder joint MRI.Methods Totally 74 subjects who underwent shoulder joint MR scanning were prospectively enrolled.Shoulder joint MRI were acquired using standard sequence(group A),PAT accelerated sequence(group B)and PAT accelerated sequence combined with DLR(group C),respectively.Subjective evaluation of overall image quality,artifacts and clarity of anatomical structures(including articular cartilages,ligaments and bone marrow)were performed using a 5-point scale,and signal-to-noise ratio(SNR)and contrast-to-noise ratio(CNR)of articular cartilages were calculated for objective evaluation,which were then compared among groups.Results No significant difference of the subjective scores of overall image quality,artifacts nor clarity of anatomical structures was found between group A and C(all P＞0.05),which were all higher than those in group B(all P＜0.05).SNR and CNR of articular cartilages of shoulder joint MRI in group C,A,B decreased in order(all P＜0.05).Conclusion PAT combined with DLR could shorten scanning time of shoulder joint MRI,reduce image noise and improve image quality.

Objective To explore the current status and potential subtypes of frailty among family caregivers of patients with dementia,and to analyze the related influencing factors of different subtypes.Methods Dementia patients and their family caregivers in 8 community health service centers in Shanghai from June to October 2023 were recruited by convenience sampling.General information questionnaire,Tilburg Frailty Indicator(TFI),Pittsburgh Sleep Quality Index(PSQI),Self-Rating Depression Scale(SDS),Zarit Caregiver Burden Interview(ZBI),and Connor-Davidson Resilience Scale(CD-RISC)were conducted for investigation.Latent profile analysis was used to explore the potential subtypes of frailty among family caregivers of patients with dementia.The influencing factors associated with the potential subtypes were identified by univariate analysis and multivariate Logistic regression analysis.Results A total of 470 family caregivers of patients with dementia were surveyed,and 46.17％of them suffered from frailty.Frailty among family caregivers of patients with dementia can be classified into 3 potential subtypes:comprehensive-low frailty subtype(70.64％),psychosocial-medium frailty subtype(19.57％),and physical-high frailty subtype(9.79％).Family caregivers of patients with dementia who had poor sleep quality and suffered from 2 or more chronic diseases were more likely to be classified into the physical-high frailty subtype(P＜0.05).Family caregivers of patients with dementia who had higher levels of depression,lower mastery levels of caregiving knowledge and skills and spousal caregivers were more likely to be classified into the psychosocial-medium frailty subtype(P＜0.05).Family caregivers of patients with dementia who had higher levels of resilience were more likely to be classified into the comprehensive-low frailty subtype(P＜0.05).Conclusion The incidence of frailty among family caregivers of patients with dementia is at a high level with significant heterogeneity.It is suggested that medical staff should pay attention to the frailty of family caregivers,with a focus on family caregivers in the psychosocial-medium frailty subtype or physical-high frailty subtype,and take timely and targeted interventions according to the characteristics and influencing factors of different subtypes,so as to prevent or delay the occurrence and development of frailty.

Objective:To evaluate the effectiveness of correcting breast ptosis using the rotational filling of an inferolaterally pedicled tongue-shaped parenchymal flap via a double periareolar incision.Methods:A retrospective study was conducted on 34 female patients (68 breasts) with breast ptosis treated at the Department of Plastic Surgery at the Affiliated Friendship Plastic Surgery Hospital of Nanjing Medical University from January 2016 to June 2023. The patients＇ ages ranged from 23 to 53 years, with an average of (37.4±7.9) years. All patients underwent correction of breast ptosis using an inferolaterally pedicled tongue-shaped parenchymal flap via a double periareolar incision. Pre-operative and post-operative measurements were taken to assess the corrective outcomes, including mammary base width (MBW), areola diameter (AD), nipple-to-nipple distance (NN), suprasternal notch-to-nipple distance (SSN-N), nipple-to-inframammary fold distance (N-IMF), and thoracic circumference at the nipple level (TN). Patients＇ satisfaction was assessed using the BREAST-questionnaire (BREAST-Q) module.Results:Postoperative first-stage wound healing was achieved in all 34 patients without complications such as hematoma, infection, or nipple necrosis. The follow-up period ranged from 6 to 60 months, with a median of 12 months. Early postoperative observations showed periareolar folds, which disappeared within 3 to 6 months in 31 cases, while mild periareolar folds, persisted for up to 12 months in 3 cases. Four patients reported reduced nipple sensation postoperatively. Measurements showed a statistically significant increase in TN and a reduction in NN, SSN-N, AD, N-IMF, and MBW compared to preoperative values (all P<0.001). BREAST-Q scores indicated significant improvements in satisfaction with breasts, psychosocial well-being and physical well-being, with preoperative scores of (21.6±8.9), (42.4±11.9) and (49.7±12.9) scores increasing to (82.3±8.5), (81.9±8.1) and (81.2±8.3) scores, respectively (all P<0.001). Conclusions:The double periareolar incision technique with rotational filling of an inferolaterally pedicled tongue-shaped glandular flap is a safe and effective method for correcting breast ptosis.
