摘要 肠道具有免疫功能,可将肠道内细菌、毒素阻隔在肠腔内,防止病原微生物及其毒素入侵人体。肠道免疫功能主要靠肠道黏膜屏障实现,各种因素(如免疫、生物、理化)损伤肠道黏膜屏障功能,将出现肠道内菌群移位、内毒素吸收等一系列病理改变[1]。采用合适的方法及时准确地评估肠道屏障功能受损程度,是有效阻止上述病理效应发生的重要手段[2]。目前肠道黏膜屏障功能的评估方法有肠黏膜通透性测定、血浆内毒素测定、肠黏膜 pH 值测定、肠型脂肪酸结合蛋白 (intestinal fatty acid binding protein, IFABP) 含量测定、血浆谷氨酰胺含量测定、大便浆细胞分泌型蛋白(sIgA)含量测定、病理检测等[3]。尿乳果糖和甘露醇比值(ratio of lactulose to mannitol, L/M),血、尿 IFABP 测定方法因其简单、快速、经济等特点,已被广泛应用。本文简述肠道黏膜屏障功能,并对尿 L/M,血、尿 IFABP用于评估肠黏膜屏障功能的研究进展进行综述。
