ObjectiveTo evaluate the efficacy and safety of Janus kinase （JAK） inhibitors combined with Chinese herbal medicine （CHM） in treating rheumatoid arthritis （RA）. MethodsClinical data from 169 RA patients were retrospectively collected. Among them， 71 cases received JAK inhibitors as the control group， while 98 cases received JAK inhibitors plus CHM as the observation group， both treated for 24 weeks. The rheumatoid factor （RF）， cyclic citic peptide antibody （anti-CCP）， erythrocyte sedimentation rate （ESR）， C-reactive protein （CRP）， and white blood cell count （WBC） were recorded before and after treatment. Databases including CNKI， Wanfang， VIP， PubMed and Web of Science were searched from inception till August 31st， 2025 for randomized controlled trials （RCTs） on the combined use of JAK inhibitors and CHM for RA. The methodological quality of the included studies was evaluated using the risk of bias assessment tool. Meta-analyses were performed for RF， anti-CCP， ESR， CRP， 28-joint disease activity score （DAS28）， overall clinical effective rate， and incidence of adverse events. Sensitivity analysis were also performed. ResultsThe retrospective study demonstrated that after treatment， ESR， CRP， and anti-CCP levels decreased in the observation group， while ESR and CRP levels decreased in the control group （P＜0.05）. Moreover， ESR and RF levels in the observation group were lower than those in the control group （P＜0.05）. A total of 9 RCTs involving 770 patients were included in the meta-analysis. The results indicated that the JAK inhibitors plus CHM group was superior to the JAK inhibitors group in reducing RF （MD=-8.97， 95%CI -15.01 to -2.94， P=0.004）， CRP （MD=-3.34， 95%CI -3.82 to -2.86， P＜0.001）， ESR （MD=-5.33， 95%CI -7.98 to -2.69， P＜0.001）， and DAS28 score （MD=-0.54， 95%CI -0.74 to -0.34， P＜0.001）， as well as in improving the overall clinical effective rate （OR=4.53， 95%CI 2.55 to 8.03， P＜0.001）. No statistically significant differences were observed between groups in anti-CCP levels （SMD=-2.08， 95%CI -4.41 to 0.24， P=0.080） or incidence of adverse events （OR=0.93， 95%CI 0.55 to 1.57， P=0.790）. ConclusionThe combination of JAK inhibitors and CHM demonstrates remarkable efficacy in treating RA， contributing to improved disease activity and reduced inflammatory markers with a favorable safety profile.

Objective: To systematically evaluate the influencing factors for autism spectrum disorder (ASD) in Chinese children, so as to provide the evidence for risk prediction and intervention of ASD. Methods: The publications pertaining to the influencing factors for ASD in Chinese children were retrieved from CNKI, Wanfang Data, VIP, PubMed and Embase database from inception to August 2024. A meta-analysis was performed using R package version 4.4.1. Sensitivity analysis was performed using the "leave-one-out" evaluation procedure. Publication bias was assessed using Egger regression test. Results: A total of 38 high-quality articles out of 9 015 articles were finally included, covering 149 607 individuals, with 5 974 cases of ASD. The meta-analysis showed that demographic factors including family history of related diseases (OR=14.958), maternal age of ≥35 years (OR=2.287) and parental history of hazardous occupations (OR=3.511); pregnancy-related factors including history of abortion (OR=5.832), no folate supplementation before and during pregnancy (OR=4.566), tobacco exposure before and during pregnancy (OR=2.596), history of other adverse exposures before and during pregnancy (OR=3.533), history of infectious diseases during pregnancy (OR=3.753), history of non-infectious diseases during pregnancy (OR=2.563), psychological problems during pregnancy (OR=3.864), history of medication during pregnancy (OR=6.651), adverse environmental exposures during pregnancy (OR=3.754), severe pregnancy reactions (OR=5.082), abnormal perinatal period (OR=2.987), cesarean delivery (OR=1.659), other perinatal adverse factors (OR=3.856), history of neonatal asphyxia (OR=2.792) and neonatal jaundice (OR=3.687); parenting factors including non-exclusive breastfeeding (OR=2.510), early/excessive screen exposure (OR=3.589) and feeding problems (OR=3.113); and individual factors including being male (OR=3.333) and history of convulsions/epilepsy (OR=7.035) were influencing factors for ASD in Chinese children. Conclusions The prevalence of ASD in Chinese children is primarily associated with 23 influencing factors, including family history of related diseases, history of abortion, no folate supplementation before and during pregnancy, medication during pregnancy, early/excessive screen exposure and history of convulsions/epilepsy.

Objective:To evaluate the association between preoperative cardiometabolic multimorbidity (CMM) and postoperative delirium (POD) in elderly patients undergoing knee or hip replacement.Methods:Based on a perioperative neurocognitive dysfunction and biomarker lifestyle cohort, a nested case-control study was conducted using medical records of patients scheduled for elective knee or hip joint replacement at Qingdao Municipal Hospital from January 2022 to November 2023. Patients were divided into POD group ( n=124) and non-POD group ( n=414) based on whether POD occurred. The influencing factors were collected, and intergroup differences were analyzed. Logistic regression was used to identify the risk factors for POD, and sensitivity analysis was conducted to assess the stability of the regression model. A mediation model was employed to examine whether cerebrospinal fluid (CSF) biomarkers mediated the association between CMM and POD. Results:There were statistically significant differences in the rate of CMM, age, years of education, rate of hypertension, rate of diabetes mellitus, rate of coronary heart diseases, rate of stroke, Aβ 42 concentration, t-tau concentration, p-tau concentration, Aβ 42/t-tau ratio, and Aβ 42/p-tau ratio in CSF between POD group and non-POD group ( P<0.05). The results of logistic regression analysis showed that preoperative CMM was a risk factor for POD ( P<0.05). Mediation analysis revealed that the relationship between CMM and POD was partly mediated by Aβ 42 concentrations in CSF. Conclusions:Preoperative CMM is a risk factor for POD in elderly patients undergoing knee or hip replacement, and the CSF Aβ 42 concentration may play a partly mediating role in the association between preoperative CMM and POD.

Inflammatory bowel disease(IBD)is a chronic inflammatory bowel disease with a complex etiology,mainly including two types:ulcerative colitis(UC)and Crohn's disease(CD),whose risk factors for its development are still incompletely understood.In recent years,Mendelian randomization(MR)has gained increasing attention in IBD research.MR mainly uses genetic variation as an instrumental variable to infer causality between exposure and outcome,effectively avoiding confounding and reverse causality in observational studies and randomised controlled trials.This review summarises currently published MR studies related to IBD,focusing on causal relationships between different risk factors and IBD development.Current findings support a causal relation-ship between IBD and selected oral diseases,skin diseases,psychiatric disorders,autoimmune diseases,bone diseases,gut diseases,gut microbiota,cytokines and nutrients,but not between IBD and lifestyle,cardiovascular diseases and neurodegenerative diseases.Despite its limitations,MR studies are of great significance in improving understanding of etiology of IBD and in identifying potential therapeutic interventions.

[Purpose]To analyze irinotecan-related adverse events(AEs)signals,to provide references for clinically safe prescribing practices.[Methods]A retrospective pharmacovigilance analysis was con-ducted using Food and Drug Administration Adverse Event Reporting System(FAERS)database from the first quarter of 2004 to the last quarter of 2024.After duplicate removal,four disproportionality analysis methods were applied:reporting odds ratio(ROR),proportional reporting ratio(PRR),Bayesian confi-dence propagation neural network(BCPNN),and empirical Bayes geometric mean(EBGM),and subgroups were analyzed by age(≥65 years old vs＜65 years old)and outcome(death vs non-death).[Results]A total of 8 456 irinotecan-related reports comprising 27 177 AEs were identified.The most frequently reported AEs included diarrhea,nausea,neutropenia,vomiting,and fatigue.Additionally,several unexpected and significant AEs signals were detected,such as cell-mediated cytotoxicity,pyomyositis,neuropathic muscular atrophy,administration site recall reaction and ischemic neuropathy.Subgroup analysis indicated that elderly patients showed higher reported frequencies of diarrhea,neutropenia and leukopenia,while younger patients had more frequent reports of nausea,vomiting and peripheral neuropathy.The median time to AEs onset was 31 d,with 49.8％occurring within the first month of treatment.[Conclusion]The AEs related to irinotecan should be paid attention to.When using irinotecan for the treatment of digestive system cancer,symptoms such as diarrhea,nausea and neutropenia should be closely monitored to reduce the risk of drug use.

Objective:Based on the theoretical domain framework, the factors that affect early ambulation in patients with mechanical ventilation were analyzed to provide evidence for improving the rehabilitation effect of patients.Methods:The mixed method of systematic review and qualitative study were adopted. Studies about factors affecting early activity of patients with mechanical ventilation searched from Cochrane Library, Embase, PubMed, Web of Science, VIP database, Wanfang Database, CNKI and SinoMed published from inception to March 19, 2024. Following literature screening and data extraction, Nvivo11 qualitative research software, content analysis and rooted theory were used to encode the text data at three levels, and the logical relationship of influencing factors were linked.Results:A total of 24 articles were selected, 351 coding elements were encoded into 14 theoretical domains, 35 secondary nodes and 42 three-level nodes were concluded. The number of coding points involving "environmental context and resources" theory domain is the largest (115 coding points), followed by the "social influences" theory domain (42 coding points). Pareto diagram was used to order and analyze the frequency of influencing factors. Patients′ physical condition (45 times) and occupational role characteristics (22 times) were the most influential single factors on early activity.Conclusions:The influencing factors of early ambulation of patients with mechanical ventilation involve all theoretical domains, and are both pluralism, blending and complex.

Objective To explore the characteristics and influencing factors of drug-induced liver injury(DILI)associated with the postoperative use of propacetamol,and to provide guidance for rational clinical medication.Methods A retrospective analysis was conducted on hospitalized patients who underwent surgical treatment and were administered propacetamol from January 2022 to June 2024.Cases were screened based on established inclusion and exclusion criteria.Statistical analyses were performed on patients'demographic data,medication information,liver function indicators before and after medication,comorbid conditions,and concomitant medications to assess the incidence and influencing factors of propacetamol-related DILI.A multivariate Logistic regression analysis was conducted to identify related risk factors.Results A total of 7,579 patients were sampled,of which 2,114 met the inclusion criteria.Among them,531 patients(25.1%)experienced DILI,primarily presenting with abnormal liver function indicators.This included elevated alanine aminotransferase in 379 cases(71.4%),elevated aspartate aminotransferase in 197 cases(37.1%),elevated alkaline phosphatase in 209 cases(39.4%),and elevated total bilirubin in 92 cases(17.3%).Univariate analysis revealed that there were significant differences in gender,height,age,weight,body mass index(BMI),duration of propacetamol use,total medication dosage,concomitant use of hepatic-metabolized antibiotics,and history of liver disease between the DILI group and non-DILI group(P<0.05).Multivariate Logistic regression analysis showed that patient gender,BMI,total propacetamol dosage,liver-related diseases,and concomitant use of hepatic-metabolized antibiotics as independent risk factors for DILI(P<0.05).Conclusion The use of propacetamol for postoperative analgesia presents a risk for liver injury,and the risk is particularly pronounced in males,obesity,high-dose dosing,patients with underlying hepatic disease,and comorbid hepatic metabolism of antimicrobial drug use.It is recommended to strengthen the monitoring of liver function in clinical application,strictly control the dosage and duration of treatment,and avoid co-administration with hepatotoxic drugs to ensure the safety of drug use.

The prevention and control of emerging and reemerging infectious diseases are crucial for national biosecurity, and surveillance and reporting of pneumonia of unknown etiology are main ways for the early detection of these diseases and mitigation of their severity. This paper summaries the surveillance methods for pneumonia of unknown etiology and emerging and reemerging infectious diseases globally, indicating that such surveillance is mainly conducted based on hospital. Western countries primarily combine active and passive surveillance while utilizing artificial intelligence technology to rapidly identify cases. China mainly use passive surveillance based on the surveillance system for pneumonia of unknown etiology, with the function of early warning in the identification of emerging infectious diseases, such as avian influenza. However, with the improvement in the surveillance system operation, the overlap with other surveillance disease systems, such as influenza, has occurred, and the improvements in case definition and operational protocol are needed. It is recommended to improve the specificity of the case definition, strenthen training in hospital staff, inclduing clinical workers and office workers, and formulate incentive mechanisms. It is necessary to emphasize the responsibility of clinicians as the main force for the detection and reporting of pneumonia of unknown etiology and emerging infectious diseases, improve the appilication of artifical intelligent technique and conduct multi-source surveillance, such as third-party testing.

Objective:To assess the effect of transversus abdominis plane block (TAPB) with liposomal bupivacaine and general anesthesia on postoperative delirium (POD) in elderly patients with prior novel coronavirus pneumonia (COVID-19).Methods:In this randomized double-blind controlled study, 416 patients of either sex, aged 65-90 yr, weighing 50-90 kg, of American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ, diagnosed as having COVID-19 within 6 months prior to surgery, who underwent laparoscopic colorectal cancer surgery under combination of elective TAPB and combined intravenous-inhalational general anaesthesia at Qingdao Municipal Hospital from June 2023 to December 2024, were selected. The patients were divided into liposomal bupivacaine group ( n=208) and bupivacaine hydrochloride group ( n=208) using the random number table method. After induction of anaesthesia, bilateral TAPB was performed with liposomal bupivacaine injectio 266 mg (40 ml) in liposomal bupivacaine group and with 0.5% bupivacaine hydrochloride 40 ml in bupivacaine hydrochloride group. The primary outcome measure was the occurrence of POD within 7 days after surgery. Secondary outcome measures included severity of POD, pain scores at 24, 48 and 72 h after operation, the rate of postoperative rescue analgesia and consumption of morphine, duration of post-anesthesia care unit stay, and length of hospital stay. The occurrence of complications such as death, reoperation, atelectasis and pneumonia was recorded at 30 days after surgery. Results:Compared with bupivacaine hydrochloride group, the incidence of POD was significantly decreased (21.5% [43/200]versus 12.0% [24/200]), pain scores at 24, 48 and 72 h after operation were decreased, the rate of postoperative rescue analgesia and consumption of morphine were decreased, and the duration of post-anesthesia care unit stay and length of hospital stay were shortened in liposomal bupivacaine group ( P<0.05). There was no significant difference in the severity of POD and the case fatality rate and related complications within 30 days after surgery between the two groups ( P>0.05). Conclusions:Liposomal bupivacaine TAPB combined with general anesthesia can reduce the development of POD in elderly patients with prior COVID-19.
