BACKGROUND: Epidemiological data on chronic diarrhea in the Chinese population are lacking, and the association between obesity and chronic diarrhea in East Asian populations remains inconclusive. This study aimed to investigate the prevalence of chronic diarrhea and its association with obesity in a representative community-dwelling Chinese population. METHODS: This cross-sectional study was based on a multistage, randomized cluster sampling involving 3503 residents aged 20-69 years from representative urban and rural communities in Beijing. Chronic diarrhea was assessed using the Bristol Stool Form Scale (BSFS), and obesity was determined based on body mass index (BMI). Logistic regression analysis and restricted cubic splines were used to evaluate the relationship between obesity and chronic diarrhea. RESULTS: The standardized prevalence of chronic diarrhea in the study population was 12.88%. The average BMI was 24.67 kg/m 2 . Of all the participants, 35.17% (1232/3503) of participants were classified as overweight and 16.13% (565/3503) as obese. After adjustment for potential confounders, individuals with obesity had an increased risk of chronic diarrhea as compared to normal weight individuals (odds ratio = 1.58, 95% confidence interval: 1.20-2.06). A nonlinear association between BMI and the risk of chronic diarrhea was observed in community residents of males and the overall participant group ( P  = 0.026 and 0.017, respectively). CONCLUSIONS This study presents initial findings on the prevalence of chronic diarrhea among residents of Chinese communities while offering substantiated evidence regarding the significant association between obesity and chronic diarrhea. These findings offer a novel perspective on gastrointestinal health management.

Objective:To understand the prevalence of depression in rural middle-aged and elderly people in Bayannur City, Inner Mongolia Autonomous Region, and to explore the relationship between arsenism and depression.Methods:In December 2016 and April 2018, a one-to-one interview questionnaire survey was conducted among middle-aged and elderly people aged 45 and above in rural areas of Bayannur City, and their depression and arsenism were analyzed. Multivariate logistic regression was used to analyze the relationship between arsenism and depression.Results:A total of 870 rural middle-aged and elderly people in Bayannur City were included, and the detection rate of depression was 15.3% (133/870). The detection rates of depression in arsenism and non-arsenism were 20.8% (37/178) and 13.9% (96/692), respectively, the difference was statistically significant (χ 2 = 4.67, P = 0.030). Multivariate logistic regression analysis after adjusting for factors associated with depression showed that people with arsenism were 1.8 times as likely to be depression compared to those without arsenism [adjusted odds ratio ( AOR) = 1.8, 95% confidence interval ( CI): 1.1 - 3.1, P < 0.05]. Conclusion:The detection rate of depression among rural middle-aged and elderly people in Bayannur City is relatively high, and arsenism may increase the risk of depression.

Objective: The clinical experience of treatment in 38 patients of Reinke′s edema by surgery of minimally invasive was reported from June 1997 to December 2000. Methods: Thirty-eight patients (25 males and 13 females, ranging in age from 46 to 67 years old) with Reinke′s edema of vocal cord were diagnosed by frequency-flash-laryngoscope and pathologic. The bilateral vocal cord stripping surgery with micro-suspension laryngoscope under general anaesthesia was completed in all 38 patients. Results: After treatment 3 months to 1 year follow-up in 33 cases, 27 cases(81.8%) had acquired good voice and only 6 cases (18.2%) had acquired lower tone voice. Conclusion: None of them had vocal cord adhesive with bilateral vocal cord mucous stripping operation which remained anterior 1/2 parts of vocal cord mucous on one side.
