Objective To analyze the status and risk factors of Helicobacter pylori (Hp) infection in permanent residents in a certain area. Methods The clinical data of 6 792 permanent residents surveyed from January 2021 to December 2023 were retrospectively analyzed. All subjects underwent 13C-urea breath test,and relevant general information was collected to analyze Hp infection status. According to whether Hp infection occurred, they were divided into positive group (n=4 283) and negative group (n=2 509). The differences in general information, living habits, and dietary habits between the two groups of subjects were analyzed, and multivariate logistic regression analysis was conducted. Results Among the 6 792 permanent residents surveyed from January 2021 to December 2023, 4283 were positive for 13C-urea breath test, accounting for 63.05% of the total. There were statistically significant differences in age distribution, gender, BMI, tableware cleaning, personal hygiene products use, chopsticks use, and raw food and vegetable cleaning between the positive group and the negative group (P<0.05). The single factors of Hp infection were substituted into multivariate logistic regression analysis equation, and it was found that age ≥45 years old, male, BMI≥24, no use of detergents to clean utensils, sharing personal hygiene products, not using public chopsticks, having a habit of eating raw food, and not cleaning vegetables before eating were independent risk factors for Hp infection. Conclusion The positive rate of Hp infection in this area is relatively high, and the infection factors are related to age, gender, and some lifestyle and dietary habits.

BackgroundSevere mental disorders represent a major public health concern due to the high disability rates and substantial disease burden, which has garnered significant national attention and prompted their inclusion in public health project management systems. However, credible evidence regarding the current status of disease management and factors influencing disease stabilization among patients with severe mental disorders in Luzhou City, Sichuan Province, remains limited. ObjectiveTo investigate the current management status of patients with severe mental disorders in Luzhou City, Sichuan Province, and to analyze influencing factors of disease stabilization among patients under standardized care, so as to provide evidence-based insights for developing targeted management strategies to optimize clinical interventions for this patient population. MethodsIn March 2023, data were extracted from the Sichuan Mental Health Service Comprehensive Management Platform for patients with severe mental disorders in Luzhou City who received management between December 2017 and December 2022. Information on mental health service utilization and clinical status changes was collected. Trend analysis was conducted to evaluate temporal changes in key management indicators for severe mental disorders in Luzhou City. Logistic regression analysis was employed to identify factors influencing the disease stabilization or fluctuation of these patients. ResultsThis study enrolled a total of 20 232 patients. In Luzhou City, the stabilization rate and standardized management rate of severe mental disorders were 94.89% and 79.36% in 2017, respectively, which increased to 95.33% and 96.92% by 2022. The regular medication adherence rate rose from 34.42% in 2018 to 86.81% in 2022. In 2022, the regular medication adherence rate was 71.80% for schizophrenia, 55.26% for paranoid psychosis, and 51.43% for schizoaffective disorder. Multivariate analysis identified the following protective factors for disease stabilization: age of 18~39 years (OR=0.613, 95% CI: 0.409~0.918), age of 40~65 years (OR=0.615, 95% CI: 0.407~0.931), urban residence (OR=0.587, 95% CI: 0.478~0.720), and regular medication adherence (OR=0.826, 95% CI: 0.702~0.973). Risk factors for disease fluctuation included poor (OR=1.712, 95% CI: 1.436~2.040), non-inclusion in care-support programs (OR=1.928, 95% CI: 1.694~2.193), non-participation in community rehabilitation (OR=2.255, 95% CI: 1.930~2.634), and intermittent medication adherence (OR=3.893, 95% CI: 2.548~5.946). ConclusionThe stability rate, standardized management rate, and regular medication adherence rate of patients with severe mental disorders in Luzhou City have shown a year-by-year increase. Age, household registration status, economic condition, medication compliance, and community-based rehabilitation were identified as influencing factors for disease fluctuation in these patients.

Objective:
Previous studies have discovered a correlation between cigarette smoking and cortical thickness and surface area, but the causal relationship remains unclear. The objective of this investigation is to scrutinize the causal association between them.
Methods:
To derive summary statistics from a genome-wide association study (GWAS) on cortical thickness, surface area, and four smoking behaviors: 1) age of initiation of regular smoking (AgeSmk); 2) smoking initiation (SmkInit); 3) smoking cessation (SmkCes); 4) cigarettes per day (CigDay). Linkage disequilibrium score regression (LDSC) was employed to examine genetic association analysis. Furthermore, for traits with significant genetic associations, Mendelian randomization (MR) analyses were conducted.
Results:
The LDSC analysis revealed nominal genetic correlations between AgeSmk and right precentral surface area, left caudal anterior cingulate surface area, left cuneus surface area, left inferior parietal surface area, and right caudal anterior cingulate thickness, as well as between CigDay and left caudal middle frontal surface area, between SmkCes and left entorhinal thickness, and between SmkInit and left rostral anterior cingulate surface area, right rostral anterior cingulate thickness, and right superior frontal thickness (rg=-0.36–0.29, p<0.05). MR analysis showed a unidirectional causal association between left caudal middle frontal surface area and CigDay (βIVW=0.056, pBonferroni=2×10-4).
Conclusion
Left caudal middle frontal surface area has the potential to serve as a significant predictor of smoking behavior.

Objective To investigate the role and mechanism of ginsenoside Rk3 in alleviating the senescence of retinal pigment epithelial(RPE)cells and in treating neovascular age-related macular degeneration(nAMD).Methods An ARPE-19 cell senescence model induced by hydrogen peroxide and an nAMD mouse model were subjected to validate the pharmacological activity of ginsenoside Rk3 in reducing RPE cell senescence and shrinking choroidal neovascularization(CNV)area.Transcriptome sequencing was performed to analyze the changes in differential gene expression profiles.Western blotting was used to detect the expression levels of mTOR,S6K1,p-S6K1,4EBP1,p-4EBP1,p62,and LC3A/B.Molecular docking and dynamics simulations were conducted to analyze the binding affinity of ginsenoside Rk3 with mTOR protein.Results ① Cell experiments showed that ginsenoside Rk3 significantly alleviated the senescence in ARPE-19 cells(P<0.05).② Animal experiments confirmed that ginsenoside Rk3 significantly reduced the retinal CNV area in nAMD mice(P<0.01),and its efficacy was comparable to the first-line clinical drug aflibercept(P>0.05).③ Transcriptome sequencing suggested that ginsenoside Rk3 led to enrichment of the PI3K-Akt signaling pathway.Western blotting showed that ginsenoside Rk3 inhibited the overactivation of mTORC1 signaling(P<0.05)and simultaneously enhanced cellular autophagy(P<0.05).④ Molecular docking and dynamics simulations further validated that ginsenoside Rk3 probably targets mTOR to alleviate RPE cell senescence.Conclusion Ginsenoside Rk3 alleviates RPE cell senescence and reduces retinal CNV area in nAMD mice by enhancing autophagy through inhibition of mTOR.

The precise and rapid monitoring of multiple organ dysfunction is crucial in drug discovery. Traditional methods, such as pathological analysis, are often time-consuming and inefficient. Here, we developed a multiplexed near-infrared window two (NIR-II) fluorescent bioimaging method that allows for real-time, rapid, and quantitative assessment of multiple organ dysfunctions. Given that existing probes did not fully meet requirements, we synthesized a range of NIR-II hemicyanine dyes (HDs) with varying absorption and emission wavelengths. By modifying these dyes, we achieved high spatial and temporal resolution imaging of the liver, kidneys, stomach, and intestines. This method was further applied to investigate disorders induced by cisplatin, a drug known to cause gastric emptying issues along with liver and kidney injuries. By monitoring the metabolic rate of the dyes in these organs, we accurately quantified multi-organ dysfunction, which was also confirmed by gold-standard pathological analysis. Additionally, we evaluated the effects of five aristolochic acids (AAs) on multiple organ dysfunction. For the first time, we identified that AA-I and AA-II could cause gastric emptying disorders, which was further validated through transcriptomics analysis. Our study introduces a novel approach for the simultaneous monitoring of multi-organ dysfunction, which may significantly enhance the evaluation of drug side effects.
