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 examine the interaction between interpersonal issues and eating behavior problems among college freshmen, and to identify core psychological factors and potential pathways that drive eating behavior.Methods:In October 2019, a total of 5 073 college freshmen from a university in Shanghai were recruited as participants. Their general demographic data were collected, and they were evaluated using the eating disorder examination questionnaire 6.0 (EDE-Q 6.0) and inventory of interpersonal problems-32(IIP-32).Descriptive analyses were performed using SPSS 24.0 software.A regularized partial correlation network was constructed using the graphical least absolute shrinkage and selection operator (GLASSO) in R(v4.2.3) software. A Bayesian network analysis (BNA) was conducted to build a directed network, aiming to identify core driving factors and key psychological mechanisms.Results:Regularized partial correlation network identified shape concern as the most central node, with the highest strength centrality(1.32) and expected influence(1.20). It showed the highest bridge strength with dominance/control (0.22, 0.21), linking the interpersonal and eating behavior modules. Directed network analysis indicated that low self-confidence was the upstream node influencing social inhibition and cold/ distant relationships, indirectly affecting eating disorder.Within the eating module, shape concern and weight concern predicted eating preoccupation and dietary restraint, forming a pathway structure from eating cognition to behavior.The network demonstrated good stability (CS-coefficient=0.75).Conclusion:Shape concern is the core mechanism underlying eating problems in college freshmen. Low self-confidence contributes indirectly via interpersonal dysfunction. Dominance/control and shape concern bridge interpersonal and eating domains, providing key targets for early prevention and intervention.

Objective:To investigate the clinical value of endometrial receptivity determination by transvaginal three-dimensional power ultrasound in the prediction of pregnancy outcome after in vitro fertilization and embryo transfer. Methods:A total of 220 infertile patients who underwent in vitro fertilization and embryo transfer in Wenzhou Hospital of Integrated Traditional Chinese and Western Medicine from July 2018 to July 2021 were included in this study. Before in vitro fertilization and embryo transfer, all patients were tested for endometrial receptivity by transvaginal two-dimensional and three-dimensional power ultrasound. Pregnancy outcomes were followed up. Anatomical indexes (endometrial thickness, endometrial volume, and endometrial morphology) and endometrial blood flow indexes [endometrial blood flow type, pulsation index, resistance index (RI), ratio of peak systolic velocity to end-diastolic velocity (S/D), vascularization index (Vl), blood flow index (FI) and vascular blood flow index (VFI)] were compared between different pregnancy outcomes. Results:There were no significant differences in endometrial thickness, endometrial volume, and endometrial morphology between successful pregnancy and failed pregnancy groups ( t or χ2 = 0.23-0.54, P = 0.523-0.890). There was no significant difference in endometrial blood flow typing between successful pregnancy and failed pregnancy groups ( χ2 = 0.217, P = 0.897). PI, RI, and S/D in the successful pregnancy group were (2.46 ± 0.29), (1.07 ± 0.21), and (0.57 ± 0.10), respectively, which were significantly lower than (2.71 ± 0.34), (1.35 ± 0.24), and (0.66 ± 0.11) in the failed pregnancy group ( t = 4.51, 5.27, 3.43, all P < 0.001). VI, FI, and VFI values in the successful pregnancy group were (23.04 ± 2.95), (32.26 ± 3.17), and (6.59 ± 0.94) respectively, which were significantly higher than (16.85 ± 2.17), (28.42 ± 3.04), and (4.88 ± 0.86) in the failed pregnancy group ( t = 10.94, 6.25, 8.37; all P < 0.001). Conclusion:Endometrial blood flow parameters such as PI, RI, S/D, VI, FI, and VFI determined by transvaginal three-dimensional power ultrasound have a certain predictive value for pregnancy outcomes after in vitro fertilization and embryo transfer. They can be used as sensitive indexes for evaluating endometrial receptivity.

Acute ischemic stroke with large vessel occlusion (AIS-LVO) refers to ischemic stroke caused by large vessel occlusion of internal carotid artery, middle cerebral artery and vertebrobasilar artery, which has the characteristics of large infarct, relatively poor outcome, higher disability and mortality. Therefore, early vascular recanalization and rescue of ischemic penumbra are the key to improve the outcome of patients with AIS-LVO. Mechanical thrombectomy (MT) has a definite effect on AIS-LVO. The current guidelines recommend that MT should be performed on the basis of IVT for AIS-LVO patients without contraindications of intravenous thrombolysis (IVT), the so-called bridging therapy. IVT can increase the risk of bleeding to a certain extent, delay MT and increase the cost of hospitalization. However, there are still many controversies about whether the patients with AIS-LVO can directly perform MT. This article reviews the comparative study of direct MT and bridging therapy in patients with anterior circulation AIS-LVO, hoping to provide reference for clinicians in the treatment of AIS-LVO.

Objective:To investigate the status of core competency of newly recruited nurses in Traditional Chinese Medicine (TCM) hospitals during the standardized training period and explore its influencing factors.Methods:From March to April 2018, new recruits of nurses from various levels of TCM hospitals in 11 provinces or municipalities directly under the central government were selected to conduct a questionnaire survey, and the results of the survey were statistically analyzed.Results:728 questionnaires were actually recovered, including 723 valid questionnaires. The total score of the core competency of newly recruited nurses in the standardized training period of the TCM hospital is (160.42±37.25) . The results of single factor analysis showed that the differences in core competency scores of nurses with different educational backgrounds, graduated colleges and working stages were statistically significant ( P<0.05) . Correlation analysis showed that the scores of occupational identity of newly recruited nurses in TCM hospitals were positively correlated with the scores of core competency ( P<0.05) . Multiple linear regression analysis showed that the types of colleges, academic qualifications, working stages, and the sense of selfdetermination, self-efficacy, Sense of organizational influence, consistency in the occupational identity were the influencing factors of nurses' core competency ( P<0.05) . Conclusions:The core competency of newly recruited nurses in TCM hospitals is affected by the types of colleges, academic qualifications, working stages, and the sense of self determination, self-efficacy, sense of organizational influence, consistency in the occupational identity. Targeted measures should be taken to improve the core competency and professional identity of newly recruited nurses, so that can enhance the cohesion of the nursing team and improve the overall level of nursing.

Objective: To evaluate the predictive value of cervical size change rate and morphological distribution detected by ultrasound in the second trimester of pregnancy for preterm delivery. Methods: From June 2016 to June 2018, 300 pregnant women who underwent antenatal testing and gave birth in , the Integrated Traditional Chinese and Western Medicine Hospital of Wenzhou were selected in this research.The length, width and shape of cervix were measured by transvaginal color doppler ultrasonography at 14 and 28 weeks respectively.According to whether or not premature delivery occurred, they were divided into premature delivery group and full-term delivery group.The differences of cervical length, cervical inner mouth width, cervical length shortening rate, cervical inner mouth width increasing rate and cervical shape distribution between preterm and full-term pregnant women were compared, and the correlation between the above indicators and the occurrence of premature delivery were analyzed. Results: The length of cervix in the preterm delivery group [(21.41±6.28)mm] was significantly shorter than that in the full-term delivery group at 28 weeks of gestation [(34.17±5.76)mm](t=10.295, P=0.000), and the width of cervical inner mouth in the preterm delivery group [(9.54±2.57) mm] was significantly longer than that in the full-term delivery group [(4.06±0.91)mm] (t=25.416, P=0.000). The shortening rate of cervical length [(39.28±8.65)%] and the increasing rate of cervical width [(149.74±15.09)%] in the preterm pregnant women during the second trimester were significantly higher than those in the full-term pregnant women [(10.15±5.29)% and (16.33±3.84)%] (t=21.471, 39.420; P=0.000, 0.000). The proportion of T-type cervix in the preterm delivery group (77.17%) was significantly higher than that in the full-term delivery group (63.28%) (χ²=10.935, P=0.001). According to the correlation analysis, the length of cervix was negatively correlated with premature birth (r=-0.612, P=0.035), and the width of cervical inner mouth, the shortening rate of cervical length in the second trimester and the increasing rate of cervical inner mouth width in the second trimester were positively correlated with premature birth (r=0.743, 0.665, 0.807; P=0.013, 0.026, 0.004). Conclusion Ultrasound monitoring of cervical size change rate and cervical morphology during the second trimester of pregnancy is helpful to the early prediction of preterm labor, which should be paid attention to clinically.
