Childhood simple obesity has become a significant public health issue in China. Modern medicine primarily relies on lifestyle interventions and often suffers from poor long-term compliance， while pharmacological options are limited and associated with potential adverse effects. Traditional Chinese Medicine （TCM） has a long history in the prevention and management of this condition， demonstrating eight distinct advantages， including systematic theoretical foundation， diversified therapeutic approaches， definite therapeutic efficacy， high safety profile， good patient compliance， comprehensive intervention strategies， emphasis on prevention， and stepwise treatment protocols. Additionally， TCM is characterized by six distinctive features： the use of natural medicinal substances， non-invasive external therapies， integration of medicinal dietetics， simple exercise regimens， precise syndrome differentiation， and diverse dosage forms. By combining internal and external treatments， TCM facilitates individualized regimen adjustment and holistic regulation， demonstrating remarkable effects in improving obesity-related metabolic indicators， regulating constitutional imbalance， and promoting healthy behaviors. However， challenges remain， such as inconsistent operational standards， insufficient high-quality clinical evidence， and a gap between basic research and clinical application. Future efforts should focus on accelerating the standardization of TCM diagnosis and treatment， conducting multicenter randomized controlled trials， and fostering interdisciplinary integration， so as to enhance the scientific validity and international recognition of TCM in the prevention and treatment of childhood obesity.

arcopenia is a systemic skeletal muscle disorder characterized by a decrease in skeletal muscle mass and progressive decline in function， with multiple signaling pathways involved in its occurrence and development. Among them， the AMP-activated protein kinase （AMPK） signaling pathway， as a key pathway regulating cellular energy homeostasis， plays an important role in the regulation of skeletal muscle metabolism and functional maintenance by improving abnormalities in glucose and lipid metabolism， balancing skeletal muscle protein synthesis and degradation， improving mitochondrial function， promoting autophagy， and inhibiting inflammatory responses and oxidative stress. This article reviews the research progress on how various traditional Chinese medicine （TCM） monomers， including polyphenols， flavonoids， and terpenoids； various traditional Chinese medicine extracts， such as those from Lycium barbarum ， Asini Corii Colla， and Panax quinquefolium ， and TCM compounds， such as Guiqi zhuangjin decoction， Jianpi qiangji granules， and Qigu capsules， intervene in sarcopenia by regulating the AMPK signaling pathway to promote muscle protein synthesis， inhibit protein degradation， improve mitochondrial function， and alleviate inflammation and oxidative stress. Additionally， their molecular mechanisms are explored. The aim is to deeply elucidate the basis of TCM in the prevention and treatment of sarcopenia and to provide theoretical support for the development of related innovative drugs.

Methods A computer-based search of PubMed, EMbase, Web of Science, Cochrane Library, Chinese Medical Journal Full-text Database, VIP, Wanfang, SinoMed and CNKI was conducted to collect studies on postoperative AL risk prediction model for esophageal cancer from their inception to October 1st, 2023. PROBAST tool was employed to evaluate the bias risk and applicability of the model, and Stata 15 software was utilized for meta-analysis. Results A total of 19 literatures were included covering 25 AL risk prediction models and 7373 patients. The area under the receiver operating characteristic curve (AUC) was 0.670-0.960. Among them, 23 prediction models had a good prediction performance (AUC>0.7); 13 models were tested for calibration of the model; 1 model was externally validated, and 10 models were internally validated. Meta-analysis showed that hypoproteinemia (OR=9.362), postoperative pulmonary complications (OR=7.427), poor incision healing (OR=5.330), anastomosis type (OR=2.965), preoperative history of thoracoabdominal surgery (OR=3.181), preoperative diabetes mellitus (OR=2.445), preoperative cardiovascular disease (OR=3.260), preoperative neoadjuvant therapy (OR=2.977), preoperative respiratory disease (OR=4.744), surgery method (OR=4.312), American Society of Anesthesiologists score (OR=2.424) were predictors for AL after esophageal cancer surgery. Conclusion At present, the prediction model of AL risk in patients with esophageal cancer after surgery is in the development stage, and the overall research quality needs to be improved.

As new evidence emerges, treatment strategies toward the functional cure of chronic hepatitis B are evolving. In 2019, a panel of national hepatologists published a Consensus Statement on the functional cure of chronic hepatitis B. Currently, an international group of hepatologists has been assembled to evaluate research since the publication of the original consensus, and to collaboratively develop the updated statements. The 2.0 Consensus was aimed to update the original consensus with the latest available studies, and provide a comprehensive overview of the current relevant scientific literatures regarding functional cure of hepatitis B, with a particular focus on issues that are not yet fully clarified. These cover the definition of functional cure of hepatitis B, its mechanisms and barriers, the effective strategies and treatment roadmap to achieve this endpoint, in particular new surrogate biomarkers used to measure efficacy or to predict response, and the appropriate approach to pursuing a functional cure in special populations, the development of emerging antivirals and immunomodulators with potential for curing hepatitis B. The statements are primarily intended to offer international guidance for clinicians in their practice to enhance the functional cure rate of chronic hepatitis B.

OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

Objective: To analyze the monitoring results of key occupational hazard factors in workplaces across different industries in Aba Tibetan and Qiang Autonomous Prefecture (Aba Prefecture), Sichuan Province, so as to provide the basis for optimizing occupational disease prevention and control measures. Methods: Data of key occupational hazard factors in workplaces in Aba Prefecture from 2022 to 2024 were collected through the Workplace Occupational Hazard Monitoring System. Descriptive analyses were conducted on the over-standard rates of occupational hazard factors, completion rates of occupational health examinations, and participation rates in occupational health training. Results: From 2022 to 2024, 165 enterprise-times in Aba Prefecture were monitored, with 112 enterprise-times exceeding the standards, the over-standard rate of enterprises was 67.88%. A total of 1 005 worksite positions were monitored, with 302 exceeding the standards, the over-standard rate of worksite positions was 30.05%. The over-standard rates of enterprises and worksite positions showed upward trends from 2022 to 2024 (both P<0.05). The over-standard rates of enterprises in the ferrous metal mining and dressing industry and non-ferrous metal mining and dressing industry were both 100%. The top three over-standard rates of worksite positions were in the non-metallic mining and dressing industry, ferrous metal mining and dressing industry, and non-ferrous metal mining and dressing industry, at 62.50%, 56.00%, and 53.13%, respectively. Worksite positions exposed to silica dust, noise, and coal dust had relatively high over-standard rates, at 17.00%, 10.04%, and 7.27%, respectively. The actual numbers of physical examinations for personnel at worksite positions with dust, chemical factors, and physical factors were 9 398, 2 469, and 10 928 person-times, respectively, with completion rates of 95.78%, 81.03%, and 100.00%, respectively. The actual number of re-examinations were 428, 129, and 1 121 person-times, respectively, with re-examination rates of 64.26%, 27.27%, and 81.53%, respectively. Among the monitored enterprises, 102 enterprise-times participated in training for persons in charge, with a participation rate of 61.82%; 108 enterprise-times participated in training for occupational health management personnel, with a participation rate of 65.45%; and 10 489 person-times of workers exposed to hazards participated in occupational health training for workers, with a participation rate of 86.24%. Conclusions The over-standard rate of key occupational hazards factors in workplaces in Aba Prefecture was relatively high. The completion rate of occupational health examinations was good, but the re-examination rate was low. It is recommended to focus on strengthening the prevention and control of occupational hazard factors in the mining and dressing industry and promoting the effective implementation of occupational health examinations and occupational health training.

his study was aimed at understanding the drug resistance of Acinetobacter baumannii,exploring the consistency between resistance genes and resistance phenotypes,and providing a basis for the rational use of antibiotics in clinical practice.A total of 88 strains of Acinetobacter baumannii were isolated from hospitals at tertiary level or above within the jurisdiction from 2021 to 2023,and subjected to drug resistance testing and whole genome sequencing.The original data were analyzed for the entire genome process with a Microobench pathogenic microorganism analysis workstation(without reference splicing),and resistance genes were predicted and annotated.The strains were subjected to multi-point sequence analysisand minimum spanning tree construction.Among 88 strains of Acinetobacter baumannii,carbapenem resistant strains(CRAB)accounted for 72.73%,and 98.44%of CRAB showed multidrug resistance.In the past three years,the resistance to multiple drugs has increased.The cgMLST analysis showed that the ST2 type accounted for 89.77%,and a new ST type was discovered.After cgMLST analysis,the minimum spanning tree was generated,and the genetic relationship of the same ST type was closer.The same ST2 type was further divided into four clusters.Binary logistic regression analysis conducted on resistance genes and resistance phenotypes revealed that resistance genes APH(3″)-Ib,armA,ADC-73,sul1,and sul2 positively correlated with resistance phenotypes.The ST2 type was the main Acinetobacter baumannii type,and showed high rates of multidrug resistance and carriage of multiple resistance genes.The drug resistance situation is severe.The consistency between common resistance genes and resistance phenotypes is good.Clinical management of Acinetobacter baumannii infection must be strengthened to prevent outbreaks and transmission.

This study investigated the disease characteristics and clinical traits of Nocardia infection,and analyzed the antibiotic resistance phenotypes,antibiotic resistance genes,and evolutionary characteristics of the strains,to provide a basis for Nocardia diag-nosis and treatment.A total of 31 Nocardia strains from a hospital in Hebei Province were collected from 2020 to 2023.The strains were identified through mass spectrometry and whole genome sequencing.Antibiotic susceptibility testing was conducted with the broth macrodilution method,and whole genome sequencing data were used to predict antibiotic resistance genes and comprehensively ana-lyze antibiotic resistance phenotypes.The 31 strains of Nocardia comprised 21 strains of Nocardia farcinica,3 strains of Nocardia ter-penica,three strains of Nocardia brasiliensis,two strains of Nocardia cyriacigeorgica,and two strains of Nocardia nova.The ceftriaxone susceptibility of 21 Nocardia farcinica strains was 85.7%,and all 31 strains were susceptible to imipenem,except for three strains of Nocardia brasiliensis.Rifampicin,aminoglycoside,and β-lactam resistance genes were found in Nocardia farcinica.Pathogenic tests should be carried out in a timely manner for suspected Nocardia infections.In clinical treatment of Nocardia infection,infected strains should be confirmed,and antibiotics should be used rationally according to the antibiotic susceptibility test results.

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.
