Obesity, as a chronic recurrent disease, has become a major public health challenge in China. To implement the requirements of the Healthy China Initiative (2019—2030), under domestic guidelines or consensus statements on overweight and obesity, and in alignment with the latest scientific advances globally, the Quality control protocol for adult overweight and obesity screening in health management (examination) institutions (2025 edition) was developed. This protocol was drafted by the Health Management Center of Shanghai Changzheng Hospital and formulated through multiple rounds of deliberation by experts in China’s health examination quality control field. The protocol establishes unified standards for screening facilities, personnel qualifications, and measurement or testing procedures. It defines specific screening items, outlines a standardized screening pathway, and sets requirements for the final medical review, ensuring the scientific validity, effectiveness, and safety of the screening process. The implementation of this protocol will enhance the consistency of weight management practices for adults across health examination institutions and strengthen the quality control of overweight and obesity screening programs.

Objective Exploring the application effect of fragmented resistance exercise in the exercise rehabili-tation of elderly patients with chronic obstructive pulmonary disease,providing references for improving their quality of life.Methods From October to December 2024,96 elderly patients with chronic obstructive pulmonary disease admitted to a tertiary hospital in Pingdingshan city were conveniently selected as the research subjects.They were randomly divided into an experimental group and a control group(all n=48)using a random number table method.The experimental group received a fragmented resistance exercise program on the basis of routine pulmonary reha-bilitation,while the control group received routine pulmonary rehabilitation nursing care for a duration of 3 months.The lung function,exercise endurance,quality of life,and exercise compliance were compared between the 2 groups before and after intervention.Results The experimental group ultimately included 46 cases,while the control group ultimately included 47 cases.The lung function of the experimental group was better than that of the control group after 3 months of intervention(P＜0.05),and the exercise compliance scores of the experimental group were high-er than those of the control group after 1 and 3 months of intervention(P＜0.001).Repeated measures ANOVA showed that there was an interaction effect(P＜0.05)in the comparison of exercise endurance and quality of life between the 2 groups.Simple effects analysis showed that the experimental group had better exercise endurance after 3 months of intervention than the control group(P＜0.05),and better quality of life after 1 and 3 months of intervention than the control group(P＜0.05).Conclusion Fragmented resistance exercise can effectively improve lung function,enhance exercise endurance and compliance,and improve quality of life in elderly patients with chronic obstructive pul-monary disease.

Age-related sarcopenia is a progressive, systemic skeletal muscle disorder associated with aging. It is primarily characterized by a significant decline in muscle mass, strength, and physical function, rather than being an inevitable consequence of normal aging. Despite ongoing research, there is still no globally unified consensus among physicians regarding the diagnostic criteria and clinical indicators of this condition. Nonetheless, regardless of the diagnostic standards applied, the prevalence of age-related sarcopenia remains alarmingly high. With the global population aging at an accelerating rate, its incidence is expected to rise further, posing a significant public health challenge. Age-related sarcopenia not only markedly increases the risk of physical disability but also profoundly affects patients’ quality of life, independence, and overall survival. As such, the development of effective prevention and treatment strategies to mitigate its dual burden on both societal and individual health has become an urgent and critical priority. Skeletal muscle regeneration, a vital physiological process for maintaining muscle health, is significantly impaired in age-related sarcopenia and is considered one of its primary underlying causes. Skeletal muscle satellite cells (MSCs), also known as muscle stem cells, play a pivotal role in generating new muscle fibers and maintaining muscle mass and function. A decline in both the number and functionality of MSCs is closely linked to the onset and progression of sarcopenia. This dysfunction is driven by alterations in intrinsic MSC mechanisms—such as Notch, Wnt/β‑Catenin, and mTOR signaling pathways—as well as changes in transcription factors and epigenetic modifications. Additionally, the MSC microenvironment, including both the direct niche formed by skeletal muscle fibers and their secreted cytokines, and the indirect niche composed of extracellular matrix proteins and various cell types, undergoes age-related changes. Mitochondrial dysfunction and chronic inflammation further contribute to MSC impairment, ultimately leading to the development of sarcopenia. Currently, there are no approved pharmacological treatments for age-related sarcopenia. Nutritional intervention and exercise remain the cornerstone of therapeutic strategies. Adequate protein intake, coupled with sufficient energy provision, is fundamental to both the prevention and treatment of this condition. Adjuvant therapies, such as dietary supplements and caloric restriction, offer additional therapeutic potential. Exercise promotes muscle regeneration and ameliorates sarcopenia by acting on MSCs through various mechanisms, including mechanical stress, myokine secretion, distant cytokine signaling, immune modulation, and epigenetic regulation. When combined with a structured exercise regimen, adequate protein intake has been shown to be particularly effective in preventing age-related sarcopenia. However, traditional interventions may be inadequate for patients with limited mobility, poor overall health, or advanced sarcopenia. Emerging therapeutic strategies—such as miRNA mimics or inhibitors, gut microbiota transplantation, and stem cell therapy—present promising new directions for MSC-based interventions. This review comprehensively examines recent advances in MSC-mediated muscle regeneration in age-related sarcopenia and systematically discusses therapeutic strategies targeting MSC regulation to enhance muscle mass and strength. The goal is to provide a theoretical foundation and identify future research directions for the prevention and treatment of this increasingly prevalent condition.

OBJECTIVE: To explore the association between acupuncture during controlled ovarian hyperstimulation (COH) and the live birth rate (LBR) using different propensity score methods. METHODS: In this retrospective cohort study, eligible women who underwent a COH were divided into acupuncture and non-acupuncture groups. The primary outcome was LBR, as determined by propensity score matching (PSM). LBR was defined as the delivery of one or more living infants that reached a gestational age over 28 weeks after embryo transfer. The propensity score model encompassed 16 confounding variables. To validate the results, sensitivity analyses were conducted using three additional propensity score methods: propensity score adjustment, inverse probability weighting (IPW), and IPW with a "doubly robust" estimator. RESULTS: The primary cohort encompassed 9751 patients (1830 [18.76%] in the acupuncture group and 7921 [81.23%] in the non-acupuncture group). Following 1:1 PSM, a higher LBR was found in the acupuncture cohort (41.4% [755/1824] vs 36.4% [664/1824], with an odds ratio of 1.23 [95% confidence interval, 1.08-1.41]). Three additional propensity score methods produced essentially similar results. The risk of serious adverse events did not significantly differ between the two groups. CONCLUSION This retrospective study revealed an association between acupuncture and an increased LBR among patients undergoing COH, and that acupuncture is a safe and valuable treatment option.

This study aims to explore different construction methods for animal models of traditional Chinese medicine(TCM)syndromes and their advantages and disadvantages,to propose optimization strategies for existing problems in current construction methods,and to provide reference for constructing animal models of TCM syndromes that both preserve the essence of TCM syndromes and conform to modern scientific research standards.Using"traditional Chinese medicine","syndrome",and"animal model"as key words,articles related to animal models of TCM syndromes from CNKI,Wanfang,and VIP databases are searched and reviewed.Then the theoretical basis,technical characteristics,and existing problems of the main construction methods of current TCM syndrome animal models are systematically sorted out,and corresponding optimization measures are proposed for the existing problems.The construction methods of TCM syndrome animal models include TCM etiology and pathogenesis construction,modern medical etiology and pathology construction,and integration of TCM and Western medicine for diseases and syndromes.The TCM etiology and pathogenesis construction method is guided by a holistic perspective,constructing syndrome models by simulating external factors such as six pathogenic factors and emotional disorders.Although it conforms to TCM theoretical connotation and has simple operation and strong controllability,this method has problems such as low modeling success rate and poor etiology-syndrome fit.The modern medical etiology and pathology construction method is based on microscopic pathological mechanisms,adopting highly controllable technical means such as drug intervention and surgical modeling.Although it has the characteristics of clear objective indicators and excellent reproducibility,this method has defects such as deviation from the essence of TCM"syndrome"and insufficient safety.The integrated TCM-Western medicine disease-syndrome method shows significant complementarity in syndrome essence restoration degree and technical feasibility,achieves systematic integration of TCM basic theories and clinical syndrome differentiation thinking in methodology,and integrates the objective evaluation system of modern medicine,improving the clinical consistency between Western medicine pathological mechanisms and TCM syndrome evolution patterns.However,this method still faces common challenges such as ambiguous syndrome identification standards and distortion of disease progression simulation.The construction of TCM syndrome animal models faces challenges such as poor theoretical adaptability and poor technical standardization,but has irreplaceable value in verifying the efficacy of prescriptions and promoting the internationalization of TCM.In the future,the construction of TCM syndrome animal models should be optimized through measures such as optimizing animal selection,improving the theoretical basis of preparation methods,standardizing the setting of modeling factors,and clarifying the standard for modeling success.

Objective To investigate the epidemiological characteristics of dengue fever in Shenzhen City in 2024, so as to provide insights into formulation of the preventive and control measures for dengue fever. Methods The epidemiological data of dengue cases reported in Shenzhen City in 2024 were extracted from the China Disease Prevention and Control Information System and field epidemiological survey data of dengue fever in Shenzhen City, and the temporal, regional and population distributions of dengue fever cases, source of acquire dengue virus infections, disease diagnosis and treatment and outbreaks were analyzed. The dengue virus nucleic acid was tested and the serotypes of dengue virus were characterized using real-time quantitative reverse transcription PCR (RT-qPCR) assay, and the dengue virus gene was sequenced using next-generation sequencing (NGS). In addition, the surveillance on the density of Aedes albopictus was performed using Breteau index (BI) and mosquito oviposition index (MOI). Results A total of 1 735 dengue fever cases were reported in Shenzhen City in 2024, including 952 local cases and 783 imported cases. Most imported dengue fever cases acquired infections from eight cities of Foshan, Guangzhou, Zhongshan, Jiangmen, Dongguan, Zhaoqing, Huizhou, and Zhuhai in the Pearl River Delta region (664 cases, 84.8% of total imported cases) into Baoan, Longgang, and Nanshan districts. The epidemic exhibited an early onset and rapid progression, peaking during the period between September and November (1 632 cases, 94.1% of total cases), and dengue fever cases were distributed across 73 subdistricts in 10 districts, with most cases reported in densely populated central and western regions. The dengue fever cases had a male-to-female ratio of 1.9∶1.0, and a median age of 37 (21) years, with a higher median age among local cases than among imported cases [40 (20) years vs. 33(15) years; Z = -10.30, P < 0.05]. Housework, unemployment, workers, and business service were predominant occupations (1 405 cases, 81.0% of total cases), and there was a significant difference in the constituent ratio of occupations between local and imported cases (χ² = 92.30, P < 0.05). Among the 1 735 dengue fever cases, the median duration from onset to definitive diagnosis was 3.3 (2.9) days, and 1 686 cases (97.2%) were identified in healthcare facilities, with a low rate of hospitalization and isolation seen in 1 701 inpatients with available epidemiological data (485 cases, 28.5% of total inpatients). A total of 29 outbreaks of dengue fever occurred in Shenzhen City across 2024, which primarily in construction sites (27 outbreaks, 93.1% of total). Dengue virus type I was the dominant serotype causing dengue fever in Shenzhen City in 2024. Sequencing showed that the genomes of dengue virus from multiple dengue fever cases in Shenzhen City shared a high sequence homology with those from cities neighboring Shenzhen City, and there might be intra-city transmission of dengue virus among multiple construction sites in Shenzhen City. The Aedes albopictus density was significantly higher in Shenzhen City in 2024 than in 2023, peaking from May to September. The annual MOI values ranged from 0.9 to 14.0, and the BI values ranged from 0.6 to 6.0. Conclusions The overall epidemic of dengue fever was severe in Shenzhen City in 2024, which was greatly affected by case importation from neighboring cities, construction sites-centered local transmission, and the effectives of routine mosquito vector control was not satisfactory. Integrated dengue fever control measures should be implemented, focusing on regional joint prevention and control mechanisms, capacity building for mosquito vector control, addressing challenges in epidemic containment at construction sites, and strengthening case detection and management systems.

Objectives:To investigate the factors influencing intraoperative blood loss in spinal metastatic tu-mor surgery and provide scientific evidence for personalized surgical planning and blood loss control measures in clinical practice.Methods:We retrospectively analyzed the clinical data of 223 patients with spinal metastatic tumors treated at the Spinal Surgery Department of Beijing Shijitan Hospital Affiliated to Capital Medical University from January 2019 to September 2024.The surgical methods included vertebroplasty,tumor resection or partial resection,vertebral body reconstruction and internal fixation,and palliative surgery.Data collected included patient demographics(age,sex,BMI,etc.),tumor characteristics(primary tumor type,vertebral metastasis location and involvement area,number of extraspinal metastases,etc.),surgical factors(surgical ap-proach,robotic assistance,operative time,etc.),and intraoperative blood loss.Univariate regression analysis was conducted on each of the above indicators,and multivariate regression analysis was performed on the in-dicators with statistical significance to identify the influence of each factor on intraoperative blood loss.Re-sults:The intraoperative blood loss was 300mL(10,1000mL).Among the 223 patients,the proportion of metastasis in the thoracic and lumbar vertebrae was relatively high,and the blood loss was relatively signifi-cant in hypervascular tumors.The amount of blood loss in the tumor resection or partial resection and verte-bral body reconstruction and internal fixation groups was greater than that in the other two groups.Univariate analysis revealed that BMI(P＜0.001),primary tumor type(P＜0.001),vertebral metastasis location(P＜0.001),verte-bral involvement area(P＜0.001),number of extraspinal metastases(P=0.03),surgical approach(P＜0.001),robotic assistance(P＜0.001),and operative time(P＜0.001)were associated with intraoperative blood loss.Multivariate analysis identified BMI(P＜0.001),primary tumor type(P=0.02),vertebral metastasis location(P=0.02)and involve-ment area(P=0.004),surgical approach(P=0.04),and operative time(P＜0.001)as the independent predictors of intraoperative blood loss.Conclusions:Intraoperative blood loss in spinal metastatic tumor surgery is influ-enced by multiple factors,including BMI,primary tumor type,vertebral metastasis location and involvement area,surgical approach,and operative time.Sufficient preoperative evaluation shall be carried out,appropriate surgical approach shall be selected,and surgical techniques shall be improved to shorten operative time.

Objective:To systematically evaluate the current status of research on the development of indicators for entrustable professional activities (EPAs) of residents in China.Methods:We searched the China National Knowledge Infrastructure, Wanfang Data, Airiti Library, PubMed, Embase, and Web of Science databases for literature on the development of EPA indicators for residents in China published between January 1, 2005 and February 28, 2025. Two researchers independently screened the literature and extracted data, followed by descriptive analysis. The quality of the studies was assessed using the Joanna Briggs Institute critical appraisal tool for expert opinion. Quantitative data were presented as medians (ranges) and qualitative data were presented as frequencies (percentages).Results:A total of eight articles were included, in which two general EPA indicator systems and six specialty-specific EPA indicator systems were developed for residents. The overall quality of the research was high, with the main shortcomings related to the methods used in the process of constructing the consensus indicators. The number of experts recruited ranged from 22 to 45, with 100.00% response rate, high authority coefficients (0.820-0.914), and high coordination coefficients (0.157-0.741). Most of the studies used literature reviews as one source for the indicator pool (8 studies, 100.00%), employed the Delphi method to reach consensus (6 studies, 75.00%), and provided inclusion criteria for the indicators (7 studies, 87.50%). However, only one study (12.50%) explored the practical application of the developed indicators, and none of the studies set indicator weights or conducted quality assessments. The number of EPA indicators developed ranged from 10 to 38 per study. The reporting of EPA indicators was included in most studies regarding titles (8 studies, 100.00%) and the expected levels of entrustment at various stages of training (6 studies, 75.00%), but the reporting on other aspects was lacking. Among the specialty-specific EPA indicators, 38.39% overlapped with the general EPAs indicators.Conclusions:The research on the development of EPA indicators for residents in China is still in its early stages, and there is room for improvement in methodological quality and reporting coverage. There is partial overlap between specialty-specific and general EPA indicators, failing to fully reflect the unique characteristics of different specialties.

Objective To investigate the expression pattern of IQGAP2 in renal cell carcinoma tissues and cell lines,and to analyze its effects on the proliferation and migration of renal cell carcinoma cells.Methods Firstly,GEO database was used to screen differentially expressed genes between renal cell carcinoma tissues,and GEPIA,TIMER2.0 were used to analyze the expression level of IQGAP2 in renal cell carcinoma tissue.Subse-quently,knockdown(siRNA)and overexpression plasmids of IQGAP2 were constructed and transfected into ACHN and 786-O cell lines to perform a series of functional experiments to evaluate the effect of IQGAP2 on the malignant biological behavior of renal carcinoma cells.qRT-PCR and Western Blot were used to detect the expres-sion of EMT(epithelial-mesenchymal transition)related proteins after knockdown and overexpression of IQGAP2.Results In renal cell carcinoma tissues,the relative expression of IQGAP2 was significantly lower than in adja-cent normal tissues(P<0.001).Transfection of si-IQGAP2 in ACHN and 786-O cells effectively downregulated the mRNA and protein expression levels of IQGAP2(P<0.01),while transfection with an overexpression plasmid significantly upregulated its mRNA and protein expression(P<0.001).Further studies revealed that overexpression of IQGAP2 significantly inhibited the proliferation(P<0.05)and migration(P<0.01)of ACHN and 786-O cells,whereas knockdown of IQGAP2 enhanced their proliferation(P<0.05,P<0.001)and migration(P<0.01).Through qRT-PCR and Western blot analyses of EMT-related proteins,it was found that reduced expression of IQGAP2 promoted the epithelial-mesenchymal transition(EMT)process in renal cancer cells.Conclusions The expression of IQGAP2 is low in renal cell carcinoma tissues and cells,and the decrease of the expression level can promote the EMT process of renal cell carcinoma cells,and then enhance the proliferation and migration of renal cell carcinoma cells.IQGAP2 plays an important tumor suppressor role in renal cell carcinoma.
