Objective:To investigate the incidence, risk factors, and bile acid profile characteristics of Crohn's disease (CD) patients complicated by gallstones.Methods:A retrospective observational study was conducted. Clinical data of CD patients admitted to Zhongda Hospital of Southeast University from January 2020 to December 2023 were collected. Patients were divided into the gallstone group and the non-gallstone group according to the presence of gallstones. Univariate analysis and Logistic multivariate analysis were perfomed to identify the risk factors of CD patients complicated by gallstones. Sixty-eight CD patients in remission were selected, and serum levels of 15 bile acids were compared between patients with and without gallstones.Results:A total of 296 CD patients were enrolled, including 211 males and 85 females, with a mean age of 37.8 ± 14.8 years, disease duration of 2.0 (1.0, 6.0) years, Crohn's disease activity index of 265.3 ± 121.2, and body mass index of 22.4±2.2 kg/m 2. Among them, 44 patients (14.9%) had gallstones and were assigned to the gallstone group, while the remaining 252 patients (85.1%) were assigned to the non-gallstone group. Univariate analysis and multivariate Logistic regression analysis showed that location was an independent risk factor for CD patients complicated by gallstones. Patients with ileocolonic CD have a 3.92-fold higher risk of developing gallstones than those with colonic CD ( OR=3.92, 95% CI: 1.13-13.61, P = 0.031). Analysis of bile acid profiles in 68 CD patients in remission revealed that, compared to those without gallstones ( n = 50), patients with gallstones ( n = 18) had lower levels of ursodeoxycholic acid and an higher ratio of secondary conjugated bile acid/secondary free bile acid, the differences were significant (both P < 0.05) . Conclusions:CD patients have a high incidence of gallstones, which may be associated with abnormal bile acid metabolism. The ileocolonic CD patients are more prone to developing gallstones.

BACKGROUND: With social development, the average life span is prolonged. The issue of aging has increasingly attracted people's attention. It is necessary to promote the health status and the guality of life of the elderly..OBJECTIVE: To understand the status and distribution features of several common diseases which influence the quality of life of elderly.DESIGN: Random cluster sampling methods and a cross-section survey.SETTING: Beijing Institute of Geriatrics of Beijing Hospital.PARTICIPANTS:Totally 1 558 old people aged ≥60 years living in 10 communities affiliated to Jianguomen district office of the Eastern District of Beijing City,and 8 villages affiliated to Xiangyang and Henan Villagers'Commissions of Shunyi County of Beijing from May 1997 and October 1997 were recruited.In fact,1 434 persons responded,with a response rate being 92％,319 males and 498 females came from the city;242 males and 375 females came from the villages.METHODS:Questionnaires were filled up,and physical examinations were conducted in all the elderly. MAIN OUTCOME MEASURES: The 6 common diseases were observed among the elderly: Hyperplasia of prostate, abnormal audition, cartaract ,osteoarthritis, fracture and constipation.RESULTS:Totally 1434 elderly entered the stage of result analysis.①The incidence of hyperplasia of prostate in the males from the urban areas was lower than that in the rural areas (61.4％,65.7％, P ＜ 0.01 ). ② The incidence of abnormal audition among the elderly from the urban areas was lower than that in the rural areas (53.9％,64.7％,P ＜ 0.01).③ The incidence of cataract of the two eyes in the elderly from the urban areas was higher than that in the rural areas(46.4％,44.4％, P ＜ 0.01). ④ The incidence of osteoarthropathy in the elderly from the urban areas was higher than that in the rural areas (24.4％,14.9, P ＜ 0.01). ⑤ The incidence of fracture in the elderly from the urban areas was higher than that in the rural areas (14.2％,9.1％, P ＜ 0.05). ⑥ The incidence of constipation of the elderly in urban areas was lower than that in the rural areas(18.2％,23.0％,P ＜ 0.05).CONCLUSION:There is a difference between the elderly from the urban areas and the rural areas in hyperplasis of prostate,abnormal audition, cataract, osteoarthropathy, fracture and constipation, and this is related with the economy, nutrition, medical conditions and cultural traits.Therefore, attention should be attached to nutrition and health knowledge of the elderly and prevention and treatment of common diseases among the elderly people.
