肠道作为机体对缺血反映最敏感的器官,在严重创伤尤其创伤-失血性休克中损伤最早,但恢复最晚[1,2]。即使当休克得到复苏的情况下,肠道的功能仍远未恢复,肠黏膜屏障损伤导致肠道的通透性增高,造成细菌及内毒素移位,肠道内细菌和内毒素逸出肠腔,进入肠淋巴管和肠系膜淋巴结,继而进入 The intestine, as the organ that is most responsive to ischemia, is the earliest one to recover from severe trauma, especially traumatic-hemorrhagic shock, [1,2]. Even when shock is recovered, the function of the intestine is still far from being restored, the damage of the intestinal mucosal barrier leads to increased permeability of the gut, resulting in the displacement of bacteria and endotoxin, the release of bacteria and endotoxins from the gut to the intestine, Into the intestinal lymphatic vessels and mesenteric lymph nodes, and then enter
