The field of post-marketing benefit-risk assessment for traditional Chinese medicine（TCM） is still in its nascent stage， lacking a universally accepted and cohesive evaluation framework and standards. This study presented a strategy developed for the benefit-risk assessment of post-marketing of TCM， and explored the critical techniques and specific implementation steps involved in the assessment process. Initially， appropriate qualitative assessment frameworks and quantitative analysis models were selected for the integrated qualitative and quantitative benefit-risk assessment. Subsequently， key technologies were outlined， including the establishment of a benefit-risk indicator system， the assignment of indicator weights， and the definition of criteria attributes. Furthermore， the implementation steps were elaborated， which involved defining decision-making issues， data collection， evaluation methodologies， variability factors， and sensitivity analysis. Finally， a case study of the benefit-risk assessment of a TCM injection for hepatitis B treatment was conducted to validate the feasibility of the proposed strategy. The objective of this research was to provide theoretical support and practical references for the development of a comprehensive post-marketing benefit-risk assessment system for TCM.

MethodThe construction of the evidence body was guided by the theory of traditional Chinese medicine（TCM） and the Technical Guiding Principles for Revision of Safety Information Items in Instructions for TCMs After Marketing， and 8 categories and 25 specific items were taken as the main body of the evidence body， and information inclusion， integration， screening and improvement were carried out， then expert demonstrations were conducted， and finally modifications were made based on the opinions of the Center for Drug Evaluation to complete the revision of the safety information in the instructions of Xiaoke'an capsules. Result［Adverse reactions］ of Xiaoke'an capsules was revised to "monitoring data show that the following adverse reactions can be seen with this product：individual hypoglycemic reaction reports". ［Contraindications］ was revised to "contraindicated for those allergic to this product and its ingredients". ［Precautions］ was revised to "（1）pregnant women should use with caution， （2）elderly people should consult a physician， （3）people with spleen deficiency and dampness， spleen and stomach deficiency and cold， or those who eat less and have diarrhea should use with caution， （4）this product contains ginseng， should not be taken at the same time with TCM prescriptions or patent medicines containing veratrum and Wulingzhi， （5）pay attention to monitoring blood sugar during medication， （6）if any other discomfort occurs during medication， you should seek medical attention in time". The warning was revised to "use with caution by pregnant women， and pay attention to regular monitoring of blood sugar". ConclusionIn accordance with the content and process of the evidence body for the revision of safety information in the instructions， the revision of the safety information in the instructions of Xiaoke'an capsules has been completed， providing a strong basis for the rational and safe use of medication in the clinic.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

Objective To explore the causal relationship between abdominal subcutaneous adipose tissue volume(ASAT)measured by MRI and cardiovascular disease risk with Mendelian randomization(MR).Methods Genome-wide association study(GWAS)data for ASAT measured by MRI were provided by the IEU OpenGWAS project,while GW AS data for cardiovascular disease came from the Finngen database.The primary analysis method employed was the inverse variance weighted(I VW)method.Additional MR analysis methods,included MR-Egger regression,weighted median(WME),simple mode method,and weighted model method.Heterogeneity,horizontal pleiotropy and leave-one-out sensitivity analysis were conducted to verify the robustness of the results and funnel plots were used to verify the evaluation.Scatter plots were used to visualize the causal relationship between ASAT and cardiovascular disease.Results There was a causal relationship between ASAT and the risk of ischemic heart disease(IHD)[odds ratio(OR)1.126,95％confidence interval(CI)1.042-1.217,P=0.003)],heart failure(HF)(OR 1.145,95％CI 1.024-1.281,P=0.017),and hypertension(OR 1.096,95％CI 1.014-1.184,P=0.021),but there was no significant causal relationship with cardiac arrest(CA)(P＞0.05).Heterogeneity was observed in the analysis of ASAT with IHD(Cochran's Q=53.467,P=0.018),HF(Cochran's Q=54.761,P=0.013),and hypertension(Cochran's Q=55.321,P=0.002).Further horizontal pleiotropy MR-Egger intercept tests and funnel plots indicated no horizontal pleiotropy in MR analysis(P＞0.05).Leave-one-out sensitivity analysis results demonstrated the robustness of the study findings.Conclusion There is a causal relationship between ASAT measured by MRI and the risk of IHD,HF,and hypertension.This highlights the need for clinical practitioners to pay attention to the cardiovascular disease risk in obese patients,especially those with abdominal obesity.

Objective To explore the mechanism of Buyang Huanwu Decoction for"treating different diseases with same therapies"in type 2 diabetes mellitus(T2DM)and Alzheimer's disease(AD)based on network pharmacology and molecular docking techniques.Methods Firstly,the active ingredients of seven herbs in Buyang Huanwu Decoction were searched and screened by TCMSP,SymMap and other databases,the target prediction of these active ingredients was carried out by PharmMapper.The disease targets of T2DM and AD were collected from OMIM,DrugBank,GeneCards and Disgenet databases.The potential targets of Buyang Huanwu Decoction for"treating different diseases with same therapies"in T2DM and AD were obtained by intersecting with targets of active ingredients and the disease targets.Then STRING database and Cytoscape software were used to construct the PPI network and"herbs-components-targets"network,respectively.The core targets and pharmacodynamic components were screened through network topology analysis.Furthermore,GO functional and KEGG enrichment analysis was performed for potential targets using Metascape database.Finally,AutoDock software was used to verify the molecular docking between the selected components and targets.Results Ninety-four active components of Buyang Huanwu Decoction can act on 342 protein targets,and 100 intersection targets were obtained by comparing with 3 140 AD targets and 1 708 T2DM targets.GO functional enrichment analysis showed that these targets were mainly involved in MAPK cascade-mediated regulation,hormone-mediated signaling pathways,cellular response to lipids,regulation of inflammation response and other biological processes.MAPK,PI3K/Akt,FoxO,AGE/RAGE,insulin resistance,lipid and atherosclerosis,and non-alcoholic fatty liver signaling pathway were significantly enriched in KEGG analysis.PPI and topology analysis of"herbs-components-targets"network were used to screen out 10 core targets such as MAPK8,MAPK14,GSK3B,PPARG,and 10 core pharmacodynamic components such as paeoniflorin,benzoyl paeoniflorin,(+)-catechin.The results of molecular docking showed that these components had strong binding ability to the targets.Conclusion The core components of Buyang Huanwu Decoction,such as paeoniflorin and catechin,may act on PPARG,GSK3B and other key targets,and participate in the regulation of signaling pathways including MAPK and PI3K/Akt,which play a role in"treating different diseases with the same therapies"of T2DM and AD.

Background::This systematic review aimed to examine whether dual-task (DT) training was superior to single-task (ST) training in improving DT walking, balance and cognitive functions for individuals with Parkinson’s disease (PD).Methods::Literature search was performed in the following electronic databases: PubMed, the Cochrane Library, Web of Science, and Metstr covering inception to May 10, 2023. And in order to facilitate comparison across trials, we calculated the effect size (Hedges’ g) of gait, balance, cognitive, and other parameters under both ST and DT conditions, using the mean change score and standard deviation (SD) of change score of the experimental and control groups. Randomized controlled trials that examined the effects of DT motor and cognitive training in individuals with Parkinson’s disease were included for this systematic review.Results::A total of 214 participants recruited from six articles (actually five trials) were involved in this review. In terms of walking ability, only double support time and stride time variability showed significant between-group difference (Hedges’ g = 0.34, 0.18, respectively). Compared to ST training group, DT training group had a more improvement effect in laboratory balance measurement (Hedges’ g = 0.18, 1.25), but no significant improvement in clinical balance measurement. No significant between-group differences were observed, thus its training effect on cognitive function was inconclusive.Conclusions::The DT training failed to achieve promising results better than ST training in improving DT walking and balance functions for individuals with PD. Any firm conclusion cannot be drawn at present, due to the limited number of eligible publications. Larger sample size and high-quality studies are needed to investigate the effectiveness of DT training in individuals with PD.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective To investigate the distribution and antimicrobial resistance profiles of the common pathogens isolated from urine from 2015 to 2021 in the CHINET Antimicrobial Resistance Surveillance Program.Methods The bacterial strains were isolated from urine and identified routinely in 51 hospitals across China in the CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021.Antimicrobial susceptibility was determined by Kirby-Bauer method,automatic microbiological analysis system and E-test according to the unified protocol.Results A total of 261 893 nonduplicate strains were isolated from urine specimen from 2015 to 2021,of which gram-positive bacteria accounted for 23.8％(62 219/261 893),and gram-negative bacteria 76.2％(199 674/261 893).The most common species were E.coli(46.7％),E.faecium(10.4％),K.pneumoniae(9.8％),E.faecalis(8.7％),P.mirabilis(3.5％),P.aeruginosa(3.4％),SS.agalactiae(2.6％),and E.cloacae(2.1％).The strains were more frequently isolated from inpatients versus outpatients and emergency patients,from females versus males,and from adults versus children.The prevalence of ESBLs-producing strains in E.coli,K.pneumoniae and P.mirabilis was 53.2％,52.8％and 37.0％,respectively.The prevalence of carbapenem-resistant strains in E.coli,K.pneumoniae,P.aeruginosa and A.baumannii was 1.7％,18.5％,16.4％,and 40.3％,respectively.Lower than 10％of the E.faecalis isolates were resistant to ampicillin,nitrofurantoin,linezolid,vancomycin,teicoplanin and fosfomycin.More than 90％of the E.faecium isolates were ressitant to ampicillin,levofloxacin and erythromycin.The percentage of strains resistant to vancomycin,linezolid or teicoplanin was＜2％.The E.coli,K.pneumoniae,P.aeruginosa and A.baumannii strains isolated from ICU inpatients showed significantly higher resistance rates than the corresponding strains isolated from outpatients and non-ICU inpatients.Conclusions E.coli,Enterococcus and K.pneumoniae are the most common pathogens in urinary tract infection.The bacterial species and antimicrobial resistance of urinary isolates vary with different populations.More attention should be paid to antimicrobial resistance surveillance and reduce the irrational use of antimicrobial agents.
