OBJECTIVE To investigate the current status of informatization tools applied to antimicrobial stewardship in county hospitals in China， and to provide a reference for promoting the informatization development of antimicrobial stewardship in county hospitals.METHODS From August to September 2025， an online questionnaire survey was conducted among 1 007 county hospitals across 31 provinces（autonomous regions， and municipalities） in China. The survey focused on the application of four types of informatization tools：the real-time monitoring system for antimicrobial use， the pre-prescription review system， the irrational use warning system， and the electronic prescription evaluation system（hereinafter referred to as the “monitoring system”“review system”“warning system”“evaluation system”，respectively）. Correlation analysis and binary Logistic regression analysis were employed to explore the influencing factors.RESULTS Of the county hospitals， 80.83% were equipped with at least one type of informatization tool for antimicrobial stewardship， while 19.17% had no relevant tool. Only 18.87% of the hospitals were equipped with all four types of tools. The monitoring system exhibited the highest equipped rate （70.80%）， whereas the warning system was equipped in only 33.96% of the hospitals. Four types of tools are evenly and adequately deployed in the eastern region， the central and western regions have far lower deployment rates of intervention tools including review system and warning system， accompanied by prominent intra-provincial gaps. The total number of the health technicians， hospital grade， and prescription review rate of outpatient antibacterial drug were significantly and positively correlated with the deployment rates of the four informatization tools （ P ＜0.05）. The results of the Logistic regression model fitting indicated that the model of the review system was rated “excellent” [area under the receiver operating characteristic curve （AUC）＝0.81]， and the model of the warning system was rated “further improvement” （AUC＝0.67）. The total number of health technicians was significantly positively correlated with the deployment rates of all four types of informatization tools （all P ＜0.05）.CONCLUSIONS The informatization of antimicrobial stewardship in county hospitals in China remains in the initial stage of transitioning from “passive statistics” to “active prevention and control”， with challenges such as structural imbalance and regional disparities. In the future， differentiated support strategies should be implemented， the allocation of resources should be optimized， to enhance the level of refined antimicrobial stewardship.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective To investigate the effects of varying pulse intervals in the programmed intermittent epidural bolus(PIEB)mode on labor analgesia in primiparous and multiparous women,and to evaluate the differ-ences in analgesic outcomes between these two groups.Methods A total of 60 primiparous and 60 multiparous women who met the inclusion criteria were recruited and randomly allocated into two groups:a 45-minute pulse interval group(P45 group,n=30)and a 60-minute pulse interval group(P60 group,n=30).Epidural labor anal-gesia was initiated when cervical dilation reached 1～3 cm.The programmed intermittent epidural bolus(PIEB)mode was started 45 minutes after analgesia commencement in the P45 group and 60 minutes after analgesia com-mencement in the P60 group.Each pulse delivered 10 ml of a solution containing 0.08%ropivacaine and 0.5 μg/ml sufentanil.Pain scores were assessed using the Visual Analog Scale(VAS)at five specific time points:baseline(t0),1 hour post-analgesia initiation(t1),2 hours post-analgesia initiation(t2),full cervical dilation(t3),and delivery(t4).Secondary outcomes included Bromage scores,the number of patient-controlled analgesia(PCA)button presses,total drug consumption,and adverse reactions.Results In primiparous women,the VAS score at t1 was significantly lower in the P45 group compared to the P60 group(P<0.05),whereas no significant differences were observed in VAS scores between the two groups at t2—t4.The median PCA press count was also significantly lower in the P45 group than in the P60 group(P<0.05).However,there were no significant differences between the groups in terms of total drug consumption,Bromage scores,or the incidence of adverse events(P>0.05).In multiparous women,no significant differences were found in VAS scores,Bromage scores,or PCA press counts between the P45 and P60 groups at any time point(P>0.05).Conversely,total drug consumption was significantly higher in the P45 group compared to the P60 group(P<0.05).Conclusions For primiparous women,a 45-minute pulse interval in the PIEB mode not only provides superior labor analgesia but also significantly reduces the frequency of PCA presses without escalating the risk or severity of motor block or adverse events.For multiparous women,the pulse interval does not substantially influence the effectiveness of labor analgesia.These findings contribute valuable new evidence for refining clinical labor analgesia protocols.

Objective:Based on the background of high-quality development,we analyze the operational efficiency of traditional Chinese medicine(TCM)hospitals in China's Yangtze River Economic Belt in 2021 and explore the impact of external environmental factors on operational efficiency,so as to provide a reference for promoting the high-quality development of TCM hospitals in the Yangtze River Economic Belt.Methods:The three-stage DEA model was used to analyze the operational efficiency of TCM hospitals in 11 provinces and cities in the Yangtze River Economic Zone in China in 2021.Results:After three-stage DEA analysis,the values of comprehensive efficiency,pure technical efficiency and scale efficiency of TCM hospitals in China's Yangtze River Economic Belt are 0.976,0.986 and 0.990,respectively.5 provinces and cities,Shanghai,Jiangsu,Hunan,Chongqing and Guizhou,are efficient before and after the adjustment,and the comprehensive efficiency of Zhejiang,Anhui,Hubei,Jiangxi,Sichuan and Yunnan have increased compared with that before the adjustment.Ranking of the average value of the comprehensive efficiency of TCM hospitals operation in the three major city clusters of the Yangtze River Economic Belt after adjustment:Chengdu-Chongqing city cluster(0.998)>city cluster in the Yangtze River Delta(0.964)>city cluster in the middle reaches of the Yangtze River(0.962).Conclusion:The operational efficiency of TCM hospitals in the Yangtze River Economic Zone has been underestimated,and the comprehensive efficiency is mainly affected by scale efficiency;there are differences in the operational efficiency of TCM hospitals in the three major urban agglomerations,and balanced development is needed between regions;the operational efficiency of TCM hospitals is affected by the external environment,and it is necessary to improve the external environment;it is necessary to strengthen the construction of digital and informatization of TCM,and to pay attention to the role of talents in TCM,so as to promote the high-quality development of TCM hospitals.

Objective To understand the current situation of healthcare-associated infection(HAI)in China,pro-vide data support and decision-making basis for formulating scientific and effective strategies for HAI prevention and control.Methods A nationwide cross-sectional survey on HAI was conducted among various types and levels of medical institutions in China according to a unified protocol of bedside surveys and case investigations.Results In 2024,a total of 5 736 medical institutions and 2 751 765 patients were surveyed.Among them,34 889 HAI cases were identified,with a prevalence rate of 1.27％.The number of HAI episodes was 38 032,and case prevalence rate was 1.38％.The prevalence rate of HAI in medical institutions in different regions of China ranged from 0.66％to 2.35％.Among medical institutions of different scales,those with a bed capacity of ≥900 had the high-est incidence of HAI,reaching 1.65％.The most common infection site was the lower respiratory tract(44.66％),followed by the urinary tract(12.94％),surgical site(9.32％),upper respiratory tract(7.02％),and bloodstream infection(5.78％).The top 3 departments with the highest HAI rates were the general intensive care unit(10.02％),department of neurosurgery(5.51％),and department(group)of hematology(5.34％).A total of 23 238 strains of HAI pathogens were detected,with 10 714 strains(46.10％)from lower respiratory tract speci-mens.The top 5 detected strains were Klebsiella pneumoniae(14.76％),Pseudomonas aeruginosa(13.33％),Escherichia coli(12.79％),Acinetobacter baumannii(9.23％),and Staphylococcus aureus(7.88％).231 944 pa-tients underwent class Ⅰ incision surgery were monitored,with 1 647 cases experienced surgical site infection,and the prevalence rate of surgical site infection was 0.71％.The number of patients who should undergo pathogen de-tection(patients receiving therapeutic and therapeutic combined prophylactic antimicrobial agents)was 715 179,while the actual number was 480 492,with a pathogen detection rate of 67.18％.425 225 patients received patho-genic detection before treatment,with a detection rate of 59.46％.Conclusion The overall HAI prevalence in Chi-na is lower,showing disparities among medical institutions of different regions and scales.Therefore,precise imple-mentation of measures is necessary for HAI prevention and control,with a focus on high-risk institutions and high-risk departments,key areas,and critical procedures.All levels of medical institutions should continuously reduce the incidence of HAI by strengthening monitoring,standardizing the use of antimicrobial agents,and reinforcing basic HAI prevention and control measures.

BACKGROUND:Unlike non-inflammatory cell apoptosis,pyroptosis is a form of inflammatory cell death,characterized by membrane integrity disruption and release of pro-inflammatory intracellular substances.Thus,it is associated with various diseases.The sirtuin family is a group of histone deacetylases dependent on nicotinamide adenine dinucleotide.In addition to deacetylation,it also possesses other enzymatic activities such as desuccinylation,demalonylation,adenosine diphosphate-ribosylation and playing crucial roles in the regulation of pyroptosis.OBJECTIVE:To review the role of the sirtuins in pyroptosis.METHODS:The first author conducted a search on PubMed,Web of Science,CNKI,and WanFang Data from inception to March 2024,using the Chinese and English search terms"Sirtuins,Sirtuin1,Sirtuin2,Sirtuin3,Sirtuin4,Sirtuin5,Sirtuin6,Sirtuin7,pyroptosis",resulting in the inclusion of 71 articles.RESULTS AND CONCLUSION:(1)The sirtuin family all participates in the regulation of pyroptosis.(2)Overexpression of sirtuin1 and sirtuin4 can inhibit pyroptosis through various pathways,thus alleviating the damage caused by pyroptosis to the organism.(3)In addition to affecting the classical pathway of pyroptosis,sirtuin3 can also inhibit pyroptosis by enhancing mitochondrial reactive oxygen species scavenging capacity and mitosis.(4)Sirtuin5 is involved in the regulation of intracellular metabolism and energy balance,including energy intake,storage,and consumption.(5)Sirtuin6 can influence pyroptosis through various pathways and also affect macrophage M1 polarization,generation of reactive oxygen species,and cleavage of pyroptosis-related factor sclerotin D to inhibit pyroptosis.(6)Overexpression of sirtuin7 can suppress pyroptosis.(7)Sirtuin2,unlike other family members,can restrain pyroptosis only after knockdown,but there are fewer reports,requiring more in-depth and comprehensive research.
