ObjectiveTo systematically assess the public health governance capacity in Zhejiang Province, to conduct an in-depth analysis of its strengths and weaknesses, so as to provide scientific basis and strategic recommendations for further enhancement. MethodsA systematic collection of policy documents, public information reports, and research literature related to public health governance capacity in Zhejiang Province from 2002 to 2023 was conducted (encompassing a total of 1 263 policy documents, 138 pieces of information reports and 631 research articles). Based on the evaluation criteria suitable for public health systems previously developed by the research team, the basic status and magnitude of change in public health governance capacity in Zhejiang Province was evaluated. Additionally, normative gap analyses were employed to identify the strengths and weaknesses. ResultsZhejiang Province ranked 4th nationwide in terms of public health governance capacity with a score of 733.4 points (1 000.0-point maximum). The province has effectively implemented the principle of health first (scoring 698.5 points in the assessment of health-first strategy implementation) and attached sufficient importance to health-related goals (scoring 658.2 points in the scientific rationality of goal setting). However, the implementation of inter-departmental coordination and incentive mechanisms only scored 178.7 points, the feasibility of management and monitoring mechanisms scored even lower at only 144.0 points, and the coverage of incentive mechanisms scored 286.0 points. ConclusionZhejiang Province has effectively implemented its health first strategy and attached great importance to health targets, but still needs to strengthen cross-departmental coordination mechanisms and health-oriented incentives.

Objective:To investigate the prevalence and risk factors of overweight and obesity among Chinese children aged 3-18 years from 11 provinces, antonomous regions, or municipalities.Methods:This national cross-sectional community health survey utilized a multistage stratified cluster-random sampling method to recruit 193 997 nationally representative participants from 11 provinces, autonomous regions, or municipalities between January 2017 and December 2019. All participants underwent physical examinations, and their caregivers completed questionnaires assessing participants′ dietary, lifestyle, familial, and perinatal information. Multilevel multinomial logistic regression models were employed to identify the potential risk factors.Results:The cohort comprised 193 997 children (102 178 boys, 91 819 girls),aged (10±4) years. Overall prevalence rates were 30 574(15.8%)overweight children and 17 217(8.9%) obesity children. Boys exhibited higher overweight and obesity rates than girls (17.0% (17 368/102 178) vs. 14.4% (13 206/102 178), 11.3% (11 553/91 819) vs. 6.2% (5 664/91 819), χ2=249.12,1 578.69,both P<0.001). The detection rates of obesity in Tanner stage 2 and 3 were the highest in boys and girls, with 13.4%(2 231/16 665) and 8.6%(880/10 221) respectively. Risk factors for obesity included parental overweight (paternal OR=2.34 and maternal OR=2.29), annual household income of 100 000-200 000 yuan (compared with<100 000 yuan, OR=1.04), higher paternal education (compared with below high school,high school and a college education OR=1.09,1.14), birth weight >4.0 kg (≤5 and>5 years old OR=1.74, 1.44,respectively), and western food consumption≥1 time/month (compared with<1, 1-2, 3-4,>4 times/month OR=1.36, 1.30, 1.67(≤5 years), 1.19, 1.16, 1.15 (>5 years), respectively) (all P<0.05). Conversely, coarse grain intake≥1 times/week (compared with<1 times/week, every day, 3-4, 1-2 times/week OR=0.74, 0.80, 0.71 (≤5 years), 0.75, 0.87, 0.90(>5 years), respectively, all P<0.05) was associated with reduced obesity risk. Conclusions:Obesity epidemiology in children demonstrates significant heterogeneity across age, gender, geographic regions, and pubertal stages. It is necessary to establish a personalized prevention and control strategy.

ObjectiveTo analyze the "compatibility" relationship of sugars and glycosides and the heat-clearing and blood-cooling effect of the roots of four varieties of Rehmannia glutinosa and provide a basis for research on the pharmacodynamic material basis and quality control of R. glutinosa. MethodsThe content of sugars and glycosides in the roots of four varieties of R. glutinosa was determined during the growth period. The principal component analysis （PCA）， orthogonal partial least squares-discriminant analysis （OPLS-DA）， and the "compatibility" relationship of active components were employed to screen out the differential samples. A rat model of bleeding due to blood heat was used to verify the pharmacodynamic differences and the potential active components of differential samples. ResultsThe content and proportion characteristics of various components in roots of the four varieties of R. glutinosa during the expansion stage and the maturity stage had obvious differences. The proportion of phenylethanoid glycosides at the maturity stage was higher than that at the expansion stage. The R. glutinosa variety 85-5 had special quality characteristics among the tested varieties. All the samples alleviated the symptoms in the rat model. The effect of clearing heat and cooling blood was different between the maturity stage and the expansion stage， as well as between 85-5 samples at the maturity stage and other samples. The effect of clearing heat and cooling blood of R. glutinosa roots was the result of the combined action of multiple components in R. glutinosa roots and might be related to the high proportions of polysaccharides， iridoid glycosides， and phenylethanoid glycosides. ConclusionThe growth stage and variety affect the quality of R. glutinosa roots. The effect of clearing heat and cooling blood of R. glutinosa roots was related to the content and proportions of various components. The study can provide a basis for the basic research on the active components and quality control of R. glutinosa.

Objective:To investigate the effect of childhood trauma on non-suicidal self-injury (NSSI) behavior in patients with depression.Method:Embase, PubMed, Cochrane Library, PsycINFO, China National Knowledge Infrastructure, Wanfang Data and China Biology Medicine dis were searched from inception to March 2024 for cross-sectional, case-control and cohort studies on childhood trauma and NSSI in patients with depression. Two researchers independently screened studies, extracted data, and assessed quality. The effect indicators were the odds ratio ( OR) of childhood trauma and school bullying to NSSI in the depressed population and the mean difference ( MD) of the childhood trauma subscale scores between the depressed population with and without NSSI. Meta-analysis was performed using Review Manager 5.3 and Stata17 software. Results:A total of 29 articles with 5 095 depressed patients were included. Childhood trauma was significantly associated with NSSI in patients with depression ( OR=2.91, 95% CI=2.01-4.21). Various forms of childhood trauma were related to NSSI behaviors in depressive patients: physical abuse ( MD=0.77, 95% CI=0.47-1.06), emotional abuse ( MD=2.99, 95% CI=2.10-3.88), physical neglect ( MD=1.17, 95% CI=0.47-1.87), emotional neglect ( MD=2.59, 95% CI=1.82-3.36), and sexual abuse ( MD=0.35, 95% CI=0.19-0.51). Additionally, school bullying among extra-family factors was identified as a risk factor for NSSI ( OR=2.16, 95% CI=1.46-3.18). Conclusion:Childhood trauma is a risk factor for NSSI behaviors in patients with depression. Different types of childhood trauma within the family, including various forms of abuse and neglect, and school bullying outside the family are related to NSSI behaviors in this population.

Objective:To investigate the role of serotonergic (5-HT) neurons activation in the dorsal raphe nucleus (DRN) in heat-induced seizures and its influence on breathing patterns in Scn1a + /- mice. Methods:24-day-old male Scn1a + /- mice were used for experiments, and sudden unexpected death in epilepsy(SUDEP) model was established through heat induction for 5 consecutive days. (1) Fluoxetine intervention experiment: 20 male mice were randomly divided into model group( n=10) and fluoxetine group ( n=10) according the weight-matched method. The fluoxetine group received intraperitoneal injection of fluoxetine (10 mg/kg) 45 min before heat induction each day for 5 consecutive days, while the model group received equal volume of 0.9% NaCl solution. (2) Chemogenetic activation experiment: 20 male mice were randomly divided into vector control group( n=10) and chemogenetic activation group ( n=10) according the weight-matched method. Empty vector or rAAV-TPH2-hM3d(Gq)-EGFP-WPREs was stereotaxically injected into DRN 14 d prior to seizure induction, and deschloroclozapine (5 mg/kg) was intraperitoneally injected 30 min before heat induction. Seizure characteristics and survival were assessed through video monitoring, and respiratory parameters were monitored. Immunofluorescence was used to detect colocalization of tryptophan hydroxylase 2(TPH2) and c-Fos in DRN. Statistical analysis was performed using SPSS 24.0 and GraphPad Prism 9.0. The independent sample t-test or Mann-Whitney test was used for inter-group comparison. Results:(1) In the fluoxetine intervention experiment: the survival rates between the model group and fluoxetine group showed no statistically significant difference ( χ2=2.23, P>0.05). As for the frequency of grade Ⅳ seizures, the model group (1.50(1.25, 2.35)min) demonstrated higher frequency than the fluoxetine group (0.43(0.20, 0.67)min) ( t=-3.40, P<0.05).With respect to respiratory parameters, the model group demonstrated shorter expiratory time ((0.10±0.02) s) and inspiratory time ((0.15±0.02) s) compared to the fluoxetine group ((0.16±0.05) s, (0.19±0.04) s) ( t=-3.47, -3.73, both P<0.01). The respiratory rate in the model group ((269.96±44.84) times/min) was significantly higher compared to the fluoxetine group ((195.04±52.37) times/min) ( t=3.44, P<0.01). The tidal volume in the model group ((0.10±0.02) mL) was significantly lower than the fluoxetine group ((0.13±0.04) mL) ( t=-2.19, P<0.05).The number of TPH2+ /c-Fos+ co-expressing cells in the model group (11.00±4.00) was lower than that in the fluoxetine group (33.00±8.39)( t=-4.16, P<0.05). (2) In the chemogenetic activation experiment: compared to the vehicle group, the chemogenetic activation group demonstrated significantly enhanced survival rates ( χ2=5.83, P<0.05). As for the frequency of grade Ⅴ seizures, the vehicle group (2.11(1.62, 3.44) times/min) showed higher frequency compared to the chemogenetic activation group (0.81(0.00, 1.62) times/min) ( t=18.00, P<0.05). In terms of respiratory parameters, the vehicle group showed shorter expiratory time ((0.10±0.01) s) and inspiratory time ((0.14±0.01) s) compared to the chemogenetic activation group ((0.12±0.01) s, (0.15±0.01) s) ( t=-2.78, -2.50, both P<0.05). The respiratory rate in the vehicle group ((208.37±9.73) times/min) was significantly higher than the chemogenetic activation group ((191.85±8.83) times/min) ( t=3.98, P<0.01). The tidal volume in the vehicle group ((0.09±0.01) mL) was significantly lower than the chemogenetic activation group ((0.12±0.02) mL) ( t=-4.77, P<0.001).The number of TPH2+ /c-Fos+ co-expressing cells in the vehicle group (9.00±3.46) was lower than that in the chemogenetic activation group (43.00±11.02)( t=-5.20, P<0.01). Conclusion:Specific activation of serotonergic neurons in the DRN can ameliorate heat-induced epileptic symptoms, improve respiratory function, and prolong survival time in Scn1a + /- mice.

Objective To investigate the predictive value of neuregulin 4(Nrg4)combined withγ-aminobutyric acid(GABA)in cognitive dysfunction among patients with severe obstructive sleep apnea-hypopnea syndrome(OSAHS).Methods A total of 169 patients with severe OSAHS were se-lected as study subjects and divided into normal cognitive function group(n=89)and cognitive dys-function group(n=80)based on cognitive function assessment results.General information of the pa-tients was collected,and the levels of Nrg4 and GABA were detected by enzyme-linked immunosor-bent assay(ELISA).Receiver operating characteristic(ROC)curve analysis was used to evaluate the predictive value of Nrg4 and GABA for cognitive dysfunction in OSAHS patients.Results The proportions of patients with a history of hypertension and diabetes,as well as the levels of diastolic blood pressure,total cholesterol(TC),triglyceride(TG),high-density lipoprotein cholesterol(HDL-C),and low-density lipoprotein cholesterol(LDL-C)were significantly higher in the cognitive dysfunction group than those in the normal cognitive function group(P＜0.05).The levels of Nrg4 and GABA were significantly lower in the cognitive dysfunction group than in the normal cognitive function group(P＜0.05).The Montreal Cognitive Assessment(MoCA)score in the cognitive dys-function group was significantly lower than that in the normal cognitive function group[(12.36±2.35)versus(28.25±1.02),P＜0.05].Multivariate Logistic regression analysis revealed that a history of hypertension and diabetes,diastolic blood pressure,TC,TG,HDL-C,and LDL-C were risk factors for cognitive dysfunction in patients with severe OSAHS(P＜0.05),while Nrg4,GABA,and MoCA scores were protective factors(P＜0.05).ROC curve analysis showed that combined de-tection of Nrg4 and GABA had a higher predictive value for cognitive dysfunction in patients with se-vere OSAHS compared with either marker alone(P＜0.05).Conclusion A history of hyperten-sion and diabetes,diastolic blood pressure,TC,TG,HDL-C,LDL-C,Nrg4,GABA,and MoCA scores are all factors influencing cognitive dysfunction in patients with severe OSAHS.Combined de-tection of Nrg4 and GABA can effectively predict cognitive dysfunction in these patients.
