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 evaluate the improvement in the outcome of intracapsular condylar fractures(ICFs)treatment with pre-cise soft tissue reduction in combination with open reduction and internal fixation(PSTR-ORIF)by comparson with traditional open reduction and internal fixation(T-ORIF).Methods:40 patients with ICFs were treated by T-ORIF and PSTR-ORIF(n=20)re-spectively.Preoperative and 6-month postoperative whole-mouth panoramic tomography,CT and MRI imaging data were analyzed,the repositioning of the soft and hard tissues of temporomandibular joints(TMJs),the Helkimo index,clinical symptoms and subjec-tive symptoms were compared between the 2 groups.Results:In PSTR-ORIF(26 sides)and T-ORIF(27 sides)groups,the rate of complete anatomical restoration of fractured segments at 6 months after surgery was 96.15％and 81.48％,and the overall effective rate of ICF articular disc restoration was 96.15％and 74.07％respectively,the height of the ascending mandibular branch was bet-ter restored in patients with B-type fracture after surgery(P＜0.05).At 6 months postoperatively,patients in the PSTR-ORIF group showed significant improvement in mouth opening,mandibular anterior extension distance,and lateral movement compared with the T-ORIF group(P＜0.05).The Helkimo index showed that the PSTR-ORIF group got a significant improvement in the complaint symptom index score and the clinical symptom index score compared with the T-ORIF group(P＜0.05).Conclusion:PSTR-ORIF is more effective than T-ORIF in the treatment of ICFs for the healing of condylar fractures,restore postoperative TMJ mobility and reduce the postoperative joint discomfort through good repositioning of soft tissues.

Objective:To analyze the effect of SBAR (situation, background, assessment, and recommendation) sign-out template in the standardized residency training in a neonatal ward.Methods:Based on SBAR communication mode, we designed and optimized neonatal ward sign-out checklist, and a total of 67 residents were trained for 2 weeks from April 2019 to June 2019, with control group (before training) and observation group (after training). The assessment indicators of sign-out information included sign-out duration, the incidence of sign-out errors, quality assessment scores and shift satisfaction (including sign-out satisfaction and self-evaluation) as well as competencies. A total of 1 553 children's morning shift data were collected, and SPSS 22. 0 was used for t test and chi-square test. Results:In the control group, the sign-out duration was (23.4±4.7) min, the incidence of sign-out errors was (43.6±6.6)%, quality assessment scores were (6.3±0.7) points, the satisfaction degree was (76.5±4.6)%, and the self-evaluation scores were (5.2±2.1) points. While, in the observation group, the sign-out duration was (15.9±3.2) min, the incidence of sign-out errors was (21.1±2.3)%, quality assessment scores were (8.9±0.9) points, the satisfaction degree was (94.1±2.9)%, and the self-evaluation scores were (8.9±0.8) points, with statistically significant difference ( P<0.05). There were statistically significant differences between the two groups in clinical skills and medical service ability [(2.2±0.1) vs. (3.8±0.3)], interpersonal communication ability [(2.6±0.5) vs. (4.2±0.1) points], teamwork ability [(3.1±0.2) vs. (4.6±0.3)], information and management ability [(2.5±0.5) vs. (4.2±0.2)] ( P<0.05). Conclusion:The SBAR template can improve sign-out process and the clinical skills of standardized training residents.

Objective To develop a high performance liquid chromatographic method (HPLC) for the analysis of of cholesterol in erythrocyte membranes.Methods The study included 167 consecutive chest pain patients who underwent coronary artery angiography in the Department of Cardiology,Nanjing General Hospital of Nanjing Command between September 2012 and February 2013.According to the clinical symptoms and t angiographic results,patients were divided into three groups:acute coronary syndrome (ACS) group (n =46),stable angina pectoris (SAP) group (n =76) and the control group (n =45).After the erythrocyte sample was hypotonically lysed and washed,saponification was carried out in a polassium hydroxide solution at 70 ℃.After extraction by Hexane/isopropanol mixture,the sample was separated on a Lichrospher column and detected by ultraviolet absorbance at 208 nm.A mobile phase composed of acetonitrile-isopropyl alcohol was found to be the most suitable for this separation.Concentrations of cholesterol in erythrocyte membranes were tested.Analysis of variance with covariates (ANOVA) was used to evaluate differences in CEM levels among groups.The relationship between continuous variables was evaluated by Spearman's correlation coefficient.Results Under the chromatographic conditions described,retention time of the cholesterol was approximately 6.1 min.Good separation and detectability of cholesterol in erythrocyte membranes were obtained.The method proved to be linear in the injection range of cholesterol from 0.05 g to 2.00 g.Cholesterol content in erythrocyte membranes were (87.0 μg/mg,75.4-98.9 μg/mg),(92.9 μg/mg,83.8-109.0 μg/mg) and (173.9 μg/mg,140.0-188.8 μ g/mg) in the control,SAP and ACS groups,respectively.Cholesterol content in erythrocyte membranes was significantly higher in ACS group than that in SAP and control groups (P ＜ 0.01).Conclusion We have successfully developed a method for the determination of cholesterol in erythrocyte membranes with good sensitivity,specificity and repeatability.
