肠源性脓毒症时,大量炎症介质的生成和释放在腹腔感染脓毒症(sepsis)导致的脏器损伤中扮演了重要角色。炎性介质持续或过多地释放可引起全身多种炎性反应、细胞活化及凝血系统和免疫系统激活,这种失控的炎症反应可以损伤血管内皮和远隔器官[1]。急性肺损伤(ALI)是腹腔感染常见 Gut-derived sepsis, a large number of inflammatory mediators generation and release plays an important role in sepsis-induced organ damage caused by abdominal infection. Sustained or excessive release of inflammatory mediators can cause multiple inflammatory reactions throughout the body, cellular activation and activation of the coagulation and immune systems, which can damage vascular endothelium and distant organs [1]. Acute lung injury (ALI) is common in abdominal infections
