Obesity, as a chronic recurrent disease, has become a major public health challenge in China. To implement the requirements of the Healthy China Initiative (2019—2030), under domestic guidelines or consensus statements on overweight and obesity, and in alignment with the latest scientific advances globally, the Quality control protocol for adult overweight and obesity screening in health management (examination) institutions (2025 edition) was developed. This protocol was drafted by the Health Management Center of Shanghai Changzheng Hospital and formulated through multiple rounds of deliberation by experts in China’s health examination quality control field. The protocol establishes unified standards for screening facilities, personnel qualifications, and measurement or testing procedures. It defines specific screening items, outlines a standardized screening pathway, and sets requirements for the final medical review, ensuring the scientific validity, effectiveness, and safety of the screening process. The implementation of this protocol will enhance the consistency of weight management practices for adults across health examination institutions and strengthen the quality control of overweight and obesity screening programs.

Objective:To present the epidemiological characteristics of ≤28 days case fatality in both hemorrhagic stroke (HS) and ischemic stroke (IS) patients in national cardiovascular disease surveillance areas from 2015 to 2019.Methods:Data on all new patients with stroke and ≤28 days outcomes from 2015 to 2019 were from the China Registry of Cardiovascular Events, which was established in 2014, covering 100 counties (cities, districts) in 31 provinces in China. Poisson regression was used to analyze the annual trend of ≤28 days case fatality. The age-standardized case fatality was directly calculated based on all new stroke onset.Results:In total, 112 069 deaths in HS patients ≤28 days after the onset, as well as 94 373 in IS patients, were identified during the study period. In 2019, the ≤28 days case fatality rate in HS patients was 4.75 times that of IS patients (37.08% vs. 7.80%), as well as that 4.06 times in urban areas (30.13% vs. 7.43%) and 5.30 times in rural areas (42.63% vs. 8.05%), respectively. Thus, in rural areas, HS patients showed 41.49% higher ≤28 days case fatality rate than that in urban areas, as well as 8.34% higher in IS patients. Those ≤28 days case fatality in both stroke subtypes onset increased with age and reached the highest level in those aged 85 years and over. During the study period, HS and IS patients in each age group displayed significant decrease trend in ≤28 days case fatality rate (trend P<0.001). Compared with that in 2015, the age-standardized ≤28 days case-fatality in HS patients in 2019 decreased by 28.52%, which was more in urban areas (-34.27%) than that in rural areas (-23.19%). Meanwhile, IS patients experienced a 39.90% reduction in ≤28 days case fatality, which was much lower in urban areas (-31.62%) than in rural areas (-45.10%, all trend P<0.001). Conclusions:From 2015 to 2019, ≤28 days case fatality in both HS and IS patients decreased in China. Wide variations of ≤28 days case-fatality were evident in the level and trend in stroke subtype, age of patients, as well as urban and rural areas. More precise and comprehensive strategies for stroke prevention, treatment, and post-stroke management are urgently required in China.

Objective:To analyze the characteristics and changes in incidence and mortality of ischemic and hemorrhagic stroke among Chinese residents from 2015 to 2019.Methods:The incidence and mortality data of ischemic and hemorrhagic stroke from 2015 to 2019 were collected from the China Registry of Cardiovascular Events (China RACE), which was established in 2014 and covered 100 counties (cities and districts) in 31 provinces in China. The age-standardized incidence rate (ASIR) was calculated using the Seventh National Census data as the standard population. The ratio of the incidence rate of ischemic stroke to hemorrhagic stroke was calculated. The subtype-specific mortality-to-incidence ratio (M/I) was calculated by the ratio of the number of deaths to the reported incidence cases. The relative ratio (RR) of M/I for ischemic to hemorrhagic stroke was calculated. The Joinpoint model was used to analyze the annual percentage change (APC) and trend of the incidence rate of stroke.Results:From 2015 to 2019, a total of 1 354 614 new stroke cases were reported, including 1 077 244 (79.52%) ischemic stroke and 277 370 (20.48%) hemorrhagic stroke cases, respectively. A total of 248 620 stroke deaths were reported, including 119 819 (48.19%) ischemic stroke deaths and 128 801 (51.81%) hemorrhagic stroke deaths. The incidence ratio of ischemic/hemorrhagic stroke from 2015 to 2019 was 3.50∶1, 3.76∶1, 3.63∶1, 4.23∶1, and 4.35∶1, respectively. From 2015 to 2019, there was no statistically significant annual trend of ASIR of ischemic stroke in overall, urban and rural areas and males ( Ptrend>0.05), while there was a downward trend in females (APC=-1.02%, Ptrend=0.042). The incidence of hemorrhagic stroke in the whole population, rural areas, males and females showed a downward trend ( Ptrend<0.05). Patients aged 45-49 years had an upward trend in the incidence rate of ischemic stroke (APC=3.82%, Ptrend=0.011), while those aged 70-74 years (APC=-7.37%, Ptrend=0.034), 80-84 years (APC=-9.75%, Ptrend=0.001) and 85 years and over (APC=-11.22%, Ptrend=0.017) presented a downward trend in the incidence of hemorrhagic stroke. During the period, the overall relative ratio of M/I (RR) for ischemic to hemorrhagic stroke was 4.2∶1, which was lower in urban than in rural areas (3.8 vs. 4.3). The largest gap between urban and rural areas was in the 55-59 age group (6.8 vs. 9.3). Conclusion:The incidence and mortality of ischemic and hemorrhagic stroke among Chinese residents are severe from 2015 to 2019, and there are regional and population differences.

Objective:Bioinformatics and experimental validation reveal the core genes of neutrophil extracellular traps(NETs)in chronic obstructive pulmonary disease(COPD).Methods:Chip data GSE8545,GSE10006,GSE11906,GSE19407 and GSE20257 were downloaded from GEO database,and the common differential expression genes(DEGs)of the first 4 datas were ob-tained through intersection and enrichment analysis were performed.Neutrophil extracellular traps differential expression genes(NETs-DEGs)were obtained by overlapping the NETs-related genes and the common DEGs,and GSE20257 was used to verify the NETs-DEGs and evaluate the diagnostic efficacy,and enrichment analysis was performed and mRNA expression level was verified in lung tissue of mice emphysema model.Results:A total of 149 common DEGs were acquired.DO analysis mainly concentrated in lung disease and COPD.GO functional annotation mainly involved in olefin metabolism,cytohormone metabolism,endoplasmic reticulum lumen,signaling receptors and oxidative stress activities.KEGG enrichment analysis mainly involved in cytochrome P450 metabo-lism,chemical carcinogenic reactive oxygen species,steroid hormone biosynthesis and phagosome,etc.GSE20257 dataset verifica-tion showed that NETs-DEGs TLR7 and CYP4F3 were up-regulated,and AUC values were 0.750 and 0.947.GO and KEGG mainly focused on fat-soluble vitamin catabolic signaling pathways,phagosomes,arachidonic acid monooxygenase activity,pattern recogni-tion receptors,arachidonic acid metabolism,Toll-like receptor signaling pathways and formation of NETs.Compared with air exposure group,mRNA expression levels of TLR7 and CYP4F3 in lung tissue of emphysema mice induced by cigarette smoke exposure were sig-nificantly increased(P<0.05).Conclusion:TLR7 and CYP4F3 may be the core genes in formation and release of NETs during the pathogenesis of COPD,which are expected to become the targets of immunotherapy for COPD.

Background Anxiety and depression are common perinatal mental health issues that often occur together and can have serious negative effects on both maternal and infant health. Objective To examine the relationships between lifestyle factors and comorbid anxiety and depression (CAD) among pregnant women in Shanghai. Methods The study estimated the prevalence of CAD during the first, second, and third trimesters of pregnancy using the Self-rating Anxiety Scale (SAS) and Center for Epidemiological Studies-Depression (CES-D) based on data from the China National Birth Cohort (CNBC) embryonic-derived diseases with assisted reproductive technology (ART) sub-cohort. Information on demographics, sleep status, nutritional intake, and exercise during each trimester was collected through self-made questionnaires, the Pittsburgh Sleep Quality Index (PSQI), and the Food Frequency Questionnaire (FFQ). Lifestyle factors (such as sleep status, nutritional intake, and exercise during each trimester) were analyzed using logistic regression and generalized linear mixed models (GLMM) to determine their impacts on the prevalence of CAD (yes or no) among pregnant women. Results A total of 2876 pregnant women were included in this study. The prevalence of CAD was 10.6% (305), 3.6% (103), and 5.5% (159) in the first, second, and third trimesters of pregnancy, respectively. The logistic regression analysis revealed that poor sleep quality throughout the entire pregnancy were statistically associated with an increased prevalence of CAD, and the odds ratios (OR) with 95% confidence intervals (CI) were 2.817 (1.845, 4.301), 2.840 (1.855, 4.347), and 9.316 (5.835, 14.876) for the first, second, and third trimesters, respectively, when compared to good sleep quality. Additionally, compared to an intake frequency of 7 times per week, the frequency of egg intake ≤3 times per week in the first trimester (OR=2.025, 95%CI: 1.197, 3.425) and the frequency of egg intake of 4–6 times per week (OR=1.896, 95%CI: 1.117, 3.216) or ≤3 times per week (OR=1.906, 95%CI: 1.082, 3.357) in the third trimester were associated with an increased risk of CAD (P<0.05). Moreover, when compared to a frequency of exercise >3 times per week, never or almost never exercising in the second trimester (OR=2.218, 95%CI: 1.220, 4.035) was associated with an increased risk of CAD (P<0.05). The GLMM analysis also demonstrated a significant association between poor sleep quality, lower exercise frequency, or lower intake frequency of vegetables, eggs, or milk and an increased risk of CAD (P<0.05). Conclusion The prevalence of CAD among pregnant women in Shanghai follows a U-shaped distribution, with the highest rate occurring in early pregnancy and the lowest rate in mid-pregnancy. Factors such as poor sleep quality, inadequate intake of vegetables, eggs, or milk, and lack of exercise during pregnancy may increase the risk of CAD. Implementing lifestyle interventions during pregnancy could potentially reduce the risk of mental health problems and improve the overall health of both mothers and babies.
