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.

Based on the previous transcriptomic experimental data of Trichinella spiralis(T.spira-lis)in this study,the larval stage specific gene TP12446 was screened and its identity in the ubiq-uitin ligase RNF family was predicted.In the study,bioinformatics methods were used to analyze its physicochemical properties and its activity to lay the foundation for further exploring the func-tion of TP12446 gene.The physicochemical properties and protein structure of TP12446 protein were predicted by bioinformatics.Its ubiquitin ligase activity was also verified by ubiquitination re-actions in vitro.The expression characteristics of TP12446 protein in different stage of T.spiralis infection were analyzed by qPCR and Western blot.Bioinformatics analysis showed that TP12446 protein was composed of 453 amino acids and its molecular weight was 51.48 kDa.The protein had a transmembrane structure and contained signal peptides.The results indicated that it was a secre-tory protein and mainly located in the cytoplasmic membrane.The protein structure analysis re-vealed that the protein contained RING and PA domain,its secondary structure was mainly com-posed of α-helix and irregular crimp and there were 10 B cell epitopes on TP12446 protein.The prediction of glycosylation and phosphorylation sites indicated that TP12446 protein contained 38 potential phosphorylation sites.Results of PPI interaction protein prediction showed that TP12446 protein had strong interaction with Usp8,Tmem37,Otub1,Otub2,Ubox5 and CD151.The results of qPCR and Western blot showed that TP12446 gene expression was the highest in the larva stage of T.spiralis,the activity of ubiquitin ligase was verified by ubiquitination reaction in vitro.TP12446 protein was a secretory hydrophobic protein with E3 ubiquitin ligase activity,which was involved in regulating cell cycle and apoptosis.

Objective:To analyze the interference of an exogenous glucose test on urinary creatinine-related renal injury biomarkers in patients with chronic kidney disease (CKD).Methods:This cross-sectional study enrolled CKD patients who visited Peking University First Hospital between October 2023 and March 2024. The patients (age: 50±18 years) included 90 males and 70 females. Fresh morning urine samples were collected, totaling 160 samples. Each urine sample was divided into 5 aliquots,each containing 225 μl. One aliquot received 75 μl of deionized water as the control. The other aliquots received 75 μl of glucose solutions at concentrations of 120, 480, 960, and 1200 mmol/L, resulting in final glucose concentrations of 30, 120, 240, and 300 mmol/L in the urine samples, respectively. Urinary creatinine in each sample was measured using both the enzymatic method and the picric acid (Jaffe) method. The following ratios were calculated: urinary albumin-to-creatinine ratio (uACR), urinary protein-to-creatinine ratio (uPCR), urinary transferrin-to-creatinine ratio (uTRF/uCr), urinary α1-microglobulin-to-creatinine ratio (uA1M/uCr), urinary immunoglobulin G-to-creatinine ratio (uIgG/uCr), and urinary N-acetyl-β-D-glucosaminidase-to-creatinine ratio (uNAG/uCr).Results:Under high glucose concentrations, significant differences ( P<0.05) were observed between the enzymatic method and the picric acid method in measuring urinary creatinine-related renal injury biomarkers. At glucose concentrations of 30, 120, 240, and 300 mmol/L, the mean percentage biases for creatinine measured by the enzymatic method were -0.19%, -0.27%, -0.20%, and -0.21%, respectively. The mean percentage biases for creatinine measured by the picric acid method were 0.78%, 1.26%, 1.35%, and 1.38%, respectively, showing an increasing deviation between the results before and after glucose addition as the glucose concentration rose. For uACR measurement, the mean absolute biases using the enzymatic method were -0.01, 1.27, 0.95, and 1.10 mg/g at the respective glucose concentrations. Using the picric acid method, the mean absolute biases for uACR were -11.69, -14.98, -16.91, and-18.51 mg/g. The biases of the picric acid method were significantly higher than the those of the enzymatic method, and the absolute value of the mean biases increased with rising glucose concentration. For uPCR, uTRF/uCr, uA1M/uCr, uNAG/uCr, and uIgG/uCr, the deviations measured by the enzymatic method were consistently smaller than those measured by the picric acid method. Conclusions:The measurement of creatinine and related renal injury biomarkers by the enzymatic method is less affected by glucose concentration. In contrast, the measurement results obtained using the picric acid method are significantly affected by glucose concentration.

BACKGROUND:The relationship between rheumatoid arthritis and coronary atherosclerosis has received extensive attention.Inflammation is related to rheumatoid arthritis and coronary atherosclerosis,indicating that there may be a common pathophysiological pathway between the two diseases.However,observational studies have not yet clarified the causal relationship.OBJECTIVE:To explore whether there is a causal relationship between rheumatoid arthritis and coronary atherosclerosis,as well as the potential causal relationship with 1 400 serum metabolites and 91 inflammatory factors through a Mendelian randomization analysis.METHODS:Coronary atherosclerosis data are from Finngen database,rheumatoid arthritis data are from IEU OpenGWAS database,serum metabolites data are from Canadian Longitudinal Study on Aging,Augsburg Cooperative Health Research and British Twin Project Research,and data of 91 inflammatory proteins are from research published in Nature Immunology in 2023.Mendelian randomization analysis was performed using data from genome-wide association studies,and causal effects were evaluated using inverse variance weighting,MR-Egger regression,weighted median,weighted model,and simple model methods,with inverse variance weighting being the primary analysis method.To enhance robustness,Cochran's Q-test MR-Egger intercept was used for sensitivity analysis.RESULTS AND CONCLUSION:(1)Inverse variance weighting results showed that rheumatoid arthritis was positively correlated with the increased relative risk of coronary atherosclerosis(odds ratio=1.002,95％confidence interval=1.001-1.003,P=0.003).There was no reverse causal relationship between coronary atherosclerosis and rheumatoid arthritis.In addition,96 serum metabolites and 9 inflammatory factors were found to have causal relationships with coronary atherosclerosis.There was a causal relationship between 51 serum metabolites and 7 inflammatory factors and rheumatoid arthritis.(2)This study provided epidemiological evidence between rheumatoid arthritis and coronary atherosclerosis,and emphasized the potential role of serum metabolites and inflammatory factors in the pathogenesis of these diseases.These findings may contribute to the development of new treatment strategies.Due to the limited inclusion of data from Asian populations,most contemporary studies used international databases and European population analyses.By collecting and analyzing the health data of European populations,it is conducive to a better understanding of the effects and potential role of Chinese medicine in Europe,and to further promote the practice of modern integration of Western and Chinese medicine.Meanwhile,through the comparative study with the European databases,it is possible to reveal the genetic differences and susceptibility to diseases among different populations,providing more dimensions and perspectives for global health research.

Objective:To construct a health education checklist for safety management of oral antitumor drugs in tumor patients, so as to provide a guidance for clinical nurses in practice, thereby improving the drug safety of patients taking oral antitumor drugs.Methods:Based on the cognition-behavior theoretical framework, a preliminary draft of a health education checklist for safety management of oral antitumor drugs in tumor patients was developed through literature review. The Delphi method was used to conduct consultations with 17 experts from July to September 2024 to revise and add or delete the contents of the checklist based on the experts' assignments of importance to the indicators at each level and the textual comments made.Results:A total of two rounds of expert consultation were conducted. The final established health education checklist for safety management of oral antitumor drugs in tumor patients included 4 primary and 28 secondary indicators. In the two rounds of consultation, the positive coefficient of experts was 100.0%, the coefficient of expert authority was 0.93, the coefficients of variation for the two rounds of expert ratings were 0 to 0.173 and 0 to 0.151, and the coefficients of Kendall's concordance were 0.141 (χ 2=74.461, P<0.001) and 0.113 (χ 2=59.549, P=0.002) , respectively. Conclusions:The health education checklist for safety management of oral antitumor drugs in tumor patients has good scientific, reliable and clinical practical value, which can provide scientific, standardized and convenient practical guidance for clinical nurses to implement health education on drug safety management for patients taking oral antitumor drugs.

The Consensus includes three primary themes: preoperative care, intraoperative care, and postoperative care, encompassing 21 secondary themes. It is characterized by scientific rigor, practical applicability, and comprehensiveness, and serves as a valuable reference and guide for clinical nursing professionals across medical institutions.

Objective:To systematically review risk prediction models for sarcopenia in community-dwelling older adults.Methods:Literature on risk prediction models for sarcopenia in community-dwelling older adults was retrieved from China National Knowledge Infrastructure, Wanfang Data, China Biology Medicine disc, VIP, PubMed, Embase, Cochrane Library, and Web of Science. The search period was from database inception to October 24, 2024. Two researchers independently screened the literature, extracted data, and assessed the risk of bias and applicability of the included studies using the Prediction Model Risk of Bias Assessment Tool (PROBAST) .Results:A total of 17 articles were included, encompassing 24 risk prediction models for sarcopenia in community-dwelling older adults. The area under the receiver operating characteristic curve ( AUC) reported in 16 studies ranged from 0.710 to 0.983. Age, sex, body mass index, body weight, calf circumference, and physical activity habits were the most frequently identified predictors. The overall risk of bias in the 17 articles was high, while applicability was generally good. Conclusions:Although the risk prediction models for sarcopenia in community-dwelling older adults show good predictive performance, methodological flaws in model development and a high risk of bias are prevalent. Future studies should strictly adhere to the PROBAST framework, optimize model construction and validation processes, and improve data handling strategies to enhance model performance and applicability.
