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.

Background The contracted family doctor services are the embodiment of the implementation of the new medical reform policy, and the transformation of the grass-roots health service mode. Studies have proved that the occupational stress in medical staff was at a high level. The enhancement of professional identity will contribute to strengthen team building，alleviate job burnout, and reduce turnover intention of family doctors. Objective To investigate the current situation of occupational identity among family doctor teams in Chengdu, to examine potential influencing factors of occupational identity, and to provide a reference for promoting career development and team building of family doctor teams. Methods Multi-stage random cluster sampling was adopted to enroll study participants form 46 primary healthcare centers where family doctor contract services were implemented among 23 districts and counties in Chengdu between March 4 and 26, 2021. A total of 2 681 family doctors participated in this survey. A self-reported survey was conducted to collect participants' demographic and occupational data. The Effort-Reward Imbalance (ERI）questionnaire was implemented to assess occupational stress. The Professional Identity Scale was used to appraise occupational identity. Results A total of 2 327 valid questionnaires were collected, with a valid recovery rate of 86.80%, involving 1 715 females (73.7%) and 612 males (26.3%), with dominant age groups of 26−35 years (43.3%) and 36−45 years (30.4%), a high proportion of being married (82.8%), having college (36.0%) and undergraduate (47.3%) education, a high proportion of primary titles (66.0%) and informal work contract (66.1%). About 88.7% of family doctor team workers reported occupational stress. The average score of occupational identity was (3.68±0.62) points. There were significant differences in occupational identity scores among different professional title, work contract, working years in medical institutions, income, and effort/reward ratio (EER) groups (P < 0.05). ERR was negatively correlated with occupational identity (r_s=−0.495, P<0.05）. The multiple regression model showed that occupational identity score in the non-staffed participants was lower than the score in the staffed ones (OR=0.429, 95%CI: 0.299−0.825). The occupational identity score in the participants having associate senior title or above was higher than in without professional title (OR=1.424, 95%CI: 1.194−2.328). The longer the working years, the higher the occupational identity score among the participants. The score of the more than 20 working years group was 1.820 times that of the less than 5 working years group (95%CI: 1.342−2.543). The higher the income, the higher the occupational identity score. The score of the 9001−12000 yuan per month group was 1.977 times that of the 1000−3000 yuan per month group (95%CI: 0.811−9.696) , and the score of the more than 12000 yuan per month group was 2.283 times that of the 1000−3000 yuan per month group (95%CI: 1.199−10.267）. Conclusion The family doctor team workers generally report occupational stress, and their occupational identity is at a medium level in Chengdu. Relevant managers should implement intervention measures against the main influencing factors to reduce their work tension and improve their occupational identity.

Objective: To explore effects of allogeneic hematopoietic stem cell transplantation (HSCT) in combination with infusion of endothelial progenitor cells (EPC) on bone marrow inflammatory injury. Methods: 6-8 weeks BALB/c (H-2K^d) mice after lethal dose of irradiation (TBI) were subjected to allogeneic bone marrow transplantation (BMT group) or co-transplantation of EPC (EPC group) . Samples of bone marrow cells of mice in each group on days 7,14,21,28 after transplantation were obtained to detect EPC cultural and cell chimeric rates by flow cytometer. Mice were sacrificed on days 7, 14, 21 and 28 post HSCT to analyze bone marrow pathology by H&E staining, the infiltration of macrophages and neutrophils by Western blot, validation expression levels of inflammatory complexes nlrp1、nlrp6 and its downstream molecules casepase-1 by Q-PCR and Western blot. Results: Cell chimeric rate on day 7 after transplantation in EPC group[ (91.65±2.77) %] was significantly higher than in BMT group[ (83.69±1.26) %]. Alleviated osteomyelitis injury and inflammatory cell infiltration in EPC group were observed when compared with BMT mice. Also significant reductions of the levels of nlrp1、nlrp6、casepase-1 transcription complexes in EPC mice were noted when compared with BMT ones. Conclusion Co-transplantation of HSC and EPC could alleviate inflammatory cell infiltration and activation of the complex to promote the repair of bone marrow.

Objective: To explore the function of NLRP1 in noninfectious pulmonary injury (nonIPI) after allogeneic stem cell transplantation (allo-HSCT) . Methods: In this study, we established the model of allo-HSCT with C57BL/6 and NLRP^-/- mouse as recipients. Chimera rate was measured by flow cytometry. The HE staining was used to observe the pathology changes in the lungs. NLRP1 and relevant inflammatory proteins were measured by Western Blot. Results: On the day 14 after allo-HSCT, the chimera rate was more than 96%, HSCs of donors had been successfully transplanted into recipients. HE staining showed that nonIPI occurred after allo-HSCT. The degrees of injuries reached the peak on day 21. In addition, the expressions of MPO, NLRP1, p20, Mature-IL-1β and Mature-IL-18 had same tends with the degrees of nonIPI. When we knocked out NLRP1 gene of recipients, the degrees of nonIPI reduced and the expressions of MPO, p20, Mature-IL-1β and Mature-IL-18 were less than in non-knockout group. Conclusion allo-HSCT could cause nonIPI and high expressions of MPO, p20, IL-1β, IL-18, NLRP1. Knocking out NLRP1 gene could alleviate the degrees of nonIPI and reduce the expressions of relevant inflammatory proteins, indicating that NLRP1 might be one of factors contributed to nonIPI after allo-HSCT.

Objective: To investigate the expression of gluconeogenic enzymes phosphoenolpyruvate carboxykinase (PEPCK) and G-6-Pase mRNA of hepatic tissue in rats with intrauterine growth retardation (IUGR) and to explore the molecular mechanism of insulin resistance in IUGR rats. Methods: Pregnant rats were randomly divided into 2 groups: a normal group and a model group. hTe normal group were fed with 21% protein forage and the model group with 10% low protein forage to obtain IUGR pup rats. hTe pup rats were introduced to the normal group and the IUGR group prospectively. At 1, 3 and 8 weeks, the body weight, blood glucose, insulin concentration andinsulin resistance index of the pup rats were measured. Expression of PEPCK and G-6-Pase mRNA were detected by RT-PCR. Results: The birth weight of the IUGR group was significantly lower than that of the normal group (P<0.001). The weight of the IUGR group was still lower than that of the normal group at 1, 3 and 8 weeks. There was no significant difference in the blood glucose, insulin level and insulin resistance index between the 2 groups (P>0.05). The hepatic expression of PEPCK and G-6-Pase mRNA in the IUGR group was significantly higher than that of the normal group at 1, 3 and 8 weeks (P<0.01). Conclusion: The significantly increased expression of PEPCK and G-6-Pase mRNA of hepatic tissue in IUGR rats may increase gluconeogenesis, which is probably one of the molecular mechanisms of insulin resistance and diabetes in IUGR.
