摘　　要：异常的肠道通透性在人类多种疾病中起着非常重要的作用,包括糖尿病、炎症性肠病、乳糜泻、多发性硬化、食物变态反应过敏症、肠易激综合征等.近年大量的研究发现:一些自身免疫性疾病伴有肠道通透性增加,这种现象发生在疾病之前,被认为与疾病的发病机制相关.研究肠黏膜屏障的功能与结构,可以提高我们对疾病的病因及病理生理认识,并且对于早期检测疾病以及对疾病进行二级预防有重要意义.目前有多种试验方法评估肠黏膜上皮细胞受损、紧密连接功能以及肠黏膜屏障的完整性.本篇综述主要探讨目前评估肠黏膜屏障功能的检测方法.Abnormal intestinal permeability has been suggested to play an important role in many human diseases,including diabetes,inflammatory bowel disease,celiac disease,multiple sclerosis,food allergy and hypersensitivity,and irritable bowel syndrome.Emerging work in recent years has begun to provide evidence for an etiologic role of abnormal intestinal permeability in the pathogenesis of autoimmune disease.Insight into gut barrier integrity and function loss is important to improve our knowledge on disease etiology and pathophysiology and contributes to early detection and/or secondary prevention of disease.A variety of tests have been developed to assess intestinal epithelial cell damage,intestinal tight junction status and consequences of intestinal barrier integrity loss,i.e.increased intestinalpermeability.This review discusses currently available methods for evaluating human intestinal barrier function.
