Using a validated postal questionnaire, we investigated the frequency of 24 gastrointestinal symptoms during the previous 3 months in a cohort of 110 young adult patients (54 males and 56 females, mean age 37.2 ± 4.7 years) with onset of Type 1 diabetes mellitus at <16 years of age. They were compared with 210 age- and sex-matched controls (104 males and 106 females). The main difference in the frequency of various symptoms between the two groups was a significant increase among the diabetic patients in upper gastrointestinal symptoms, such as loss of appetite (17.8% vs 3.6%, p < 0.001), early satiety (26.8% vs 6.1%, p < 0.001), nausea (22.7% vs 9.1%, p < 0.01) and vomiting (12.2% vs 3.0%, p < 0.01). No difference was noted in the frequency of symptoms from the lower gastrointestinal tract, apart from a significant increase in the feeling of incomplete defaecation (28.6% vs 17.0%, p < 0.04) in the diabetic patients. Patients with levels of haemoglobin A1c in the highest quartile had significantly more gastrointestinal symptoms than other diabetic patients. Further, the prevalence of symptoms was higher in females than in males. In conclusion, long-term Type 1 diabetes is accompanied by a markedly increased frequency of upper gastrointestinal symptoms, mainly in females and patients with poor metabolic control. 相似文献

Cellular senescence is a biologically irreversible state of cell-growth arrest that occurs following either a replicative or an oncogenic stimulus. This phenomenon occurs as a response to the presence of premalignant cells and appears to be an important anticancer mechanism that keeps these transformed cells at bay. Many exogenous and endogenous triggers for senescence have been recognized to act via genomic or epigenomic pathways. The most common stimulus for senescence is progressive loss of telomeric DNA, which results in the loss of chromosomal stability and eventual unregulated growth and malignancy. Senescence is activated through an interaction between the p16 and p53 tumor-suppressor genes. Senescent cells can be identified in vitro because they express senescence-associated β-galactosidase, a marker of increased lysosomal activity. Cellular senescence plays an integral role in the prevention and development of both benign and malignant gastrointestinal diseases. The senescence cascade and the cell-cycle checkpoints that dictate the progression and maintenance of senescence are important in all types of gastrointestinal cancers, including pancreatic, liver, gastric, colon, and esophageal cancers. Understanding the pathogenic mechanisms involved in cellular senescence is important for the development of agents targeted toward the treatment of gastrointestinal tumors. 相似文献

胃肠起搏治疗肠易激综合征疗效观察 总被引:3,自引:0,他引:3
背景:肠易激综合征(IBS)是临床常见消化系统疾病,业已证实胃肠动力障碍是其病因之一。胃肠起搏是近年兴起的治疗胃肠动力障碍性疾病的新方法,但其疗效尚不明确。目的:评价胃肠起搏治疗IBS的疗效。方法:60例符合罗马Ⅱ标准的IBS患者随机分为2组,治疗组予胃肠起搏治疗,每周5天,每天50min.疗程4周;对照组服用谷维素20mg tid,疗程4周。治疗前后进行胃肠道症状评分。结果:胃肠起搏治疗对IBS患者腹痛和(或)腹部不适程度和频度、腹胀程度和频度以及排便次数和粪便性状的改善具有显著疗效(P〈0.05),但对异常排便疗效不明显(P〉0.05)。结论:胃肠起搏能明显改善IBS患者的胃肠道症状,是一种较好的治疗方法。 相似文献

With pet ownership on the rise, millions of individuals are exposed to this environmental exposure. Although the subject has been largely studied, more evidence is needed to clarify the potential association of pet ownership with human health. The aim of this research is to study the potential association of pet exposure (any pet, cat, dog, bird, fish) with all-cause, cardiovascular and cancer mortality of older ( 50 years) European residents. To this end, a total of 23,274 participants from the Survey of Health Ageing and Retirement in Europe (SHARE) were employed (median follow-up 119 months). All-cause mortality (5163 events), as well as cardiovascular (CVD) (1832 events), and cancer mortality (1346 events) were examined using Cox Proportional Hazards models for their relation with pet exposure at baseline. Stratified analyses were also performed by gender and for single or multi-person households. No significant association was observed for any of the pets with all-cause mortality on the whole sample and the fully adjusted models. In stratified analyses, bird exposure significantly increased the risk of all-cause mortality in women [Hazard Ratio ; 95% CI 1.04–1.44] as well as women living alone ; 95% CI 1.02–1.85). Cause-specific models revealed an increased risk of death for women bird owners for causes other than cancer and CVD ; 95% CI 1.05–1.99). In conclusion, bird ownership may be negatively associated with survival of older women in Europe. 相似文献
