肠粘膜屏障损害与肠外/肠内营养的近代概念

肠道在维持机体正常营养中起着极其重要的作用。在创伤、手术、放疗、化疗、严重感染、重症胰腺炎等应激状态或长期进行肠外营养的情况下,肠道粘膜的结构和功能可能受到严重损害,可导致肠功能衰竭(障碍),甚至发生多脏器功能衰竭而危及生命。早期诊断肠屏障损害有重要临床意义。肠粘膜屏障损害病人常需肠外与肠内营养支持。在当前肠外与肠内营养重要的改进趋势中,包括谷氨酰胺和生长激素的应用。本文阐述了肠粘膜屏障损害的概况、诊断方法及肠外/肠内营养中应用谷氨酰胺和生长激素对肠粘膜屏障功能的改进等。

Cut barrier dysfunction and parenteral/enteral nutrition update

The gut plays an important role on maintaining the normal nutritional status. Critical illness and long term parenteral nutrition may lead to bowel barrier function deterioration and endotoxin/bacterial translocation. GLN combined with rHGH had some synergetic effect on supporting bowel barrier function. This article vill be an overview of the earlier diagnosis of bowel barrier dysfunction and the application of GLN and rHGH in parentetal nutritional support to improve the bowel barrier fumction.
