Objective: To investigate the association between overweight, obesity, central obesity and hypertension, so as to provide the basis for formulating targeted hypertension prevention and control strategies. Methods: Permanent residents aged ≥18 years were selected in Wenzhou City, Zhejiang Province from June 2023 to August 2024 by a multistage cluster random sampling method. Data on demographic information, lifestyle, height, weight, waist circumference (WC), blood pressure, and blood biochemical indicators were collected through questionnaire surveys, physical examinations, and laboratory tests. The prevalence of hypertension was calculated and standardized using the data of the Sixth National Population Census in 2010. Body mass index (BMI) was calculated to determine overweight and obesity, while WC was used to identify central obesity. The association between overweight, obesity, central obesity and hypertension were analyzed using multivariable logistic regression models. Results: A total of 38 593 residents were surveyed, including 19 481 (50.48%) males and 19 112 (49.52%) females. The median age was 46.00 (interquartile range, 26.00) years. The rates of overweight, obesity, and central obesity were 32.74% (12 634 individuals), 10.27% (3 963 individuals), and 27.87% (10 755 individuals), respectively. There were 11 813 cases of hypertension, with a prevalence and standardized prevalence of 30.61% and 24.41%, respectively. Multivariable logistic regression analysis showed that after adjusting for demographic information, lifestyle, diabetes and dyslipidemia, the likelihood of hypertension in the overweight and obesity groups was 1.927 (95%CI: 1.815-2.045) times and 3.724 (95%CI: 3.404-4.073) times that of the normal BMI group, respectively. The likelihood of hypertension in the central obesity group was 2.346 (95%CI: 2.214-2.486) times that of the normal WC group. The likelihood of hypertension in the central obesity only, overweight only, overweight with central obesity, obesity only and obesity with central obesity groups was 1.586 (95%CI: 1.391-1.809), 1.704 (95%CI: 1.582-1.835), 2.433 (95%CI: 2.254-2.626), 1.768 (95%CI: 1.424-2.194), and 4.466 (95%CI: 4.053-4.921) times that of the normal BMI and WC group, respectively. Conclusions Overweight, obesity and central obesity were all associated with hypertension among adult residents. The highest likelihood of hypertension was observed among adult residents with both general obesity and central obesity.

Background Occupational stress has been shown to be an important factor affecting the mental health of workers. The role of affective commitment to the organization and overcommitment to work cannot be ignored. However, there is a lack of research on this topic in China. Objective To explore a potential mediating effect of affective commitment on how occupational stress affects the mental health of medical staff and a potential moderating effect of overcommitment on the mediating effect of affective commitment. Methods A total of 1372 health care workers in a tertiary Grade A hospital in Lanzhou City were selected as study subjects for a cross-sectional survey. The occupational stress, emotional commitment, and psychological distress of the subjects were evaluated by the Effort-Reward Imbalance Scale, Affective Commitment Scale, and Kessler 10 Scale. SPSS 26.0 was used for correlation analysis, mediation analysis, and moderated mediation analysis. Common method bias wasevaluated by Harman one-factor test. Results A total of 1372 questionnaires were distributed, of which 1277 valid questionnaires were returned, with a valid recovery rate of 93.08%. The mean occupational stress score was 1.14±0.23, the mean overcommitment score was 20.26±3.21, the mean affective commitment score was 20.25±3.34, and the mean psychological distress score was 26.26±7.90. The Spearman correlation analysis results showed that occupational stress among medical staff was positively correlated with overcommitment and psychological distress (r=0.153, 0.410, P＜0.01) and negatively correlated with affective commitment (r=−0.341, P＜0.01); overcommitment was negatively related to affective commitment and positively related to psychological distress (r=−0.107, 0.312, P＜0.01); affective commitment was negatively related to psychological distress (r=−0.464, P＜0.01). The positive effect of occupational stress on psychological distress of medical staff was significant (b=0.41, t=15.42, P<0.001); affective commitment presented a partial mediating effect on the relationship between occupational stress and psychological distress (effect value=0.13), accounting for 31.71% of the total effect; overcommitment moderated the process of occupational stress-affective commitment-psychological distress (P＜0.01). Conclusion Affective commitment of medical staff has a partial mediating effect on the relationship between occupational stress and psychological distress, and overcommitment plays a significant role in moderating the process of occupational stress-affective commitment-psychological distress.

Objective To observe the effects of live combined bifidobacterium,lactobacillus and enterococcus powder on immunoglobulin E (IgE) and interleukin-17 (IL-17) in atopic children with bronchiolitis.Methods Sixty cases of atopic children with bronchiolitis were randomly divided into the therapy group (30 cases) and the control group (30 cases).Twenty-five healthy children were enrolled as the healthy control group.Both the therapy group and the control group were given traditional therapy.The therapy group received live combined bifidobacterium,lactobacillus and enterococcus powder for 2 months.The change of IgE and IL-17 levels were observed during the acutestage,remission stage and after receiving live combined bifidobacterium,lactobacillus and enterococcus powder for 2months.Results (1) The levels of IgE and IL-17 of therapy group[(132.36 ±9.50) μg/L and (77.76 ±7.95)μg/L] during acute stage were markedly higher than those in the healthy control group [(52.80 ±4.92) μg/L and (46.92 ±4.79) μg/L] (all P ＜0.001).The levels of IgE and IL-17 of control group [(128.83 ± 8.06) μg/L and (76.61 ±6.18) μg/L] during remission stage were markedly higher than those in the healthy control group [(52.80 ±4.92) μg/L and (46.92 ± 4.79) μg/L] (all P ＜ 0.001).(2) The levels of IgE of therapy group (56.67 ± 9.20)μg/L after receiving live combined bifidobacterium,lactobacillus and enterococcus powder for 2 months were markedly lower than those in the control group (70.50 ± 11.38) μg/L (P ＜ 0.001).The levels of IL-17 of therapy group [(49.63 ± 6.35) μg/L] at the time after receiving live combined bifidobacterium,lactobacillus and enterococcus powder for 2 months were markedly lower than these in the control group (54.77 ± 6.33) μg/L (P =0.003).Conclusion Receiving live combined bifidobacterium,lactobacillus and enterococcus powder for two months can decrease the IgE and IL-17 levels in atopic children with bronchiolitis.

Objective To evaluate the efficacy of intravenous immunoglobulin (IVIG) in the treatment of severe EV71 infection in children.Methods The clinical data of children with severe EV71 infection,who admitted in our hospital from January 2010 to November 2012 were retrospectively analyzed.According to the time of admission and treatment principles,the patients were divided into the 2010 group and the 2012 group.The patients of the 2010 group routinely received IVIG treatment,but patients in the 2012 group received IVIG treatment in serious condition.The obvious effective rate,effective rate,ineffective rate,the incidence rate of critically ill and mortality of the two groups were compared.Results There were no significant differences in the obvious effective rate (86.0％ and 85.2％),effective rate (9.6％ and 11.8％),ineffective rate (4.4％ and 3.0％),the incidence rate of critically ill (4.0％ and 2.2％) between the two groups (x2 =0.011,1.269,1.657,3.304,all P ＞ 0.05).The mortality of the 2010 group (2.8％) was higher than that of the 2012 group (0.6％)(x2 =8.213,P ＜0.05).Conclusion IVIG has no effect on patients with severe EV71 infection,and is not recommended.
