OBJECTIVE: This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study. METHODS: A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants. RESULTS: Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m ²) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m ²) and obesity (≥ 28.0 kg/m ²) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m ² ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses. CONCLUSION This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

Objective To investigate the effect and mechanism of pomalidomide(POM)on airway inflammation and mucus hypersecretion in rats with chronic obstructive pulmonary disease(COPD).Methods Thirty-six SD rats were randomly divided into control group,model group and POM group,with 12 in each group,half male and half female.The COPD model was established by smoke exposure combined with Klebsiella pneumoniae infection in model group and POM group.The rats in POM group were treated with POM(0.5 mg/kg,once a day for 1 week).The lung function,lung tissue pathology,the proportion of inflammatory cells in bronchoalveolar lavage fluid(BALF)and the levels of serum inflammatory factors tumor necrosis factor-α(TNF-α),interleukin(IL)-1β,IL-6 and IL-13 were observed and detected in each group.AB-PAS staining and immunohistochemistry were used to analyze the proliferation of goblet cells and the secretion of mucin(MUC)5AC and MUC5B in airway epithelium of rats.The expression levels of TNF-α receptor 1(TNFR1),IκB kinase(IKK),phosphorylated IKK(p-IKK)and P65 protein in lung tissue were detected by Western blotting.Results Compared with control group,model group showed significant decreased of tidal volume(TV),minute ventilation(MV),forced expiratory vital capacity(FVC),0.1s forced expiratory volume(FEV0.1)and 0.3 s forced expiratory volume(FEV0.3)(P<0.05),increased of the mean linear intercept(MLI)of the alveoli(P<0.01),decreased of the mean alveolar number(MAN)(P<0.01),increased of the proportion of neutrophils and lymphocytes in BALF sediment(P<0.05),and decreased of the proportion of macrophages in BALF sediment(P<0.01);increased of the levels of serum inflammatory factors TNF-α,IL-1β,IL-13 and IL-6(P<0.05),the proportion of goblet cells in airway epithelium(P<0.01),the secretion of MUC5AC and MUC5B in lung tissue(P<0.01),the content of TNFR1 and the ratio of p-IKK/IKK(P<0.01),the content of P65 in nucleus(P<0.01);and decreased of the content of P65 in cytoplasm(P<0.05).Compared with model group,after one week of POM treatment,POM group showed significant improved of the TV,MV,FVC,FEV0.1,FEV0.3,MLI and MAN of rats(P<0.05);decreased of the proportion of neutrophils and lymphocytes in BALF(P<0.05);increased of the proportion of macrophages(P<0.01);decreased of the levels of serum TNF-α,IL-1β,IL-6 and IL-13(P<0.05),the proportion of goblet cells in airway(P<0.01),the secretion of MUC5AC and MUC5B(P<0.01),and the expression of TNFR1,P-IKK and P65(nucleus)(P<0.05);and increased of the level of P65(cytoplasm)(P<0.01).Conclusions POM can improve airway inflammation and mucus hypersecretion in COPD rats,which may be achieved by inhibiting TNF-α/NF-κB signaling pathway.

Objective To explore the relationship between community health follow-up management and the quality of life of residents receiving home care from long-term care insurance(LTCI),and provide a basis for the construction of an integrated community home care service model centered on disabled residents.Methods According to the inclusion and exclusion criteria,and the principle of convenience,a sample was selected consisting of residents who participated in LTCI home care from Jan 1 to Dec 31,2021,in Meilong Community of Minhang District,Shanghai.After a year of participation,the subjects'quality of life was assessed face-to-face by trained community doctors using the 36-item short form health survey(SF-36).Based on the electronic health records of residents,the community chronic disease management system,the LTCI management system,and combined with on-site questionnaire survey,community doctors collected the demographic information,lifestyle,types of diseases,chronic disease comorbidity status,and health follow-up management provided by primary medical and health institutions.To assess the association between community health follow-up management and residents'quality of life with home care insurance for elderly care through cross-sectional analysis.Results The survey revealed that 230(57.64%)individuals had indeed received health follow-up management provided by the community health service center.The scores of the general health,physiological function,physical pain,mental health,vitality,and emotional function dimensions on the SF-36 scale were found to be higher compared to those of no follow-up population.The difference between the two groups exhibited statistical significance(all P＜0.05).Furthermore,individuals who actively engaged in the health follow-up management provided by community health service centers exhibited significantly higher scores in terms of health change(P=0.003),indicating a relatively favorable overall health status.After adjusting for demographic and confounding variables,further analysis revealed a significant positive association between health follow-up management provided by community health service centers and the overall health,physiological function,physical pain,mental health,and vitality dimensions of the SF-36 scale among LTCI beneficiaries(all P＜0.05).Conclusion The provision of health follow-up management by community health service centers exerts a significant positive impact on the quality of life among disabled residents covered by LTCI.It is an effective way to improve the quality of LTCI home care services.

Wnt/β-catenin is a signaling pathway associated with embryonic development, organ formation, cancer, and fibrosis. Its activation can repair kidney damage during acute kidney injury (AKI) and accelerate the occurrence of renal fibrosis after chronic kidney disease (CKD). Interestingly, p53 has also been found as a key modulator in AKI and CKD in recent years. Meantime, some studies have found crosstalk between Wnt/β-catenin signaling pathways and p53, but more evidence is required on whether they have synergistic effects in renal disease progression. This article reviews the role and therapeutic targets of Wnt/β-catenin and p53 in AKI and CKD and proposes for the first time that Wnt/β-catenin and p53 have a synergistic effect in the treatment of renal injury.

Objective To study the intervention effect of narrative therapy on non-suicidal self-injury(NSSI),as well as anxiety and depression symptoms in adolescents with depressive disorder.Methods Sixty adolescents with depressive disorder and NSSI were randomly assigned to either the intervention group or the control group using coin flipping.The control group received conventional psychological support,while the intervention group received individual narrative therapy in addition to the conventional psychological support(twice a week,60 minutes per session,for a total of 3 weeks).Assessment of treatment efficacy was conducted using the Adolescent Self-Harm Questionnaire,Children's Depression Inventory,and Children's Anxiety and Mood Scale before the intervention,at the end of the intervention,and one month after the intervention for both groups.Results A total of 26 adolescents in the intervention group and 29 adolescents in the control group completed the entire study.At the end of the intervention and one month after the intervention,the intervention group showed a significant reduction in the NSSI frequency score,NSSI level,anxiety score,and depression score compared to before the intervention(P<0.017).Moreover,at the end of the intervention and one month after the intervention,the intervention group exhibited significantly lower NSSI frequency score,NSSI severity score,NSSI level,anxiety score and depression score compared to the control group(P<0.05).Conclusions Narrative therapy is effective in reducing NSSI frequency and alleviating NSSI severity,as well as anxiety and depression symptoms in adolescents with depressive disorder.[Chinese Journal of Contemporary Pediatrics,2024,26(2):124-130]
