目的 探讨早期免疫生态肠内营养对重症急性胰腺炎(SAP)大鼠肝功能的保护作用.方法 选取健康雄性SD大鼠120只随机分为假手术对照组(SO组),重症急性胰腺炎模型组(SAP组),早期肠内营养组(EEN),早期生态免疫营养组(EIN)4组.将每组分为12、24、48 h三个亚组(n=10).除假手术对照组外,其余各组大鼠采用逆行胰胆管注射5%牛磺胆酸钠制备SAP模型.采集大鼠腹主动脉血检测血清淀粉酶(AMY)、脂肪酶(LPS)、丙氨酸氨基转氨酶(ALT)、天门冬氨酸氨基转移酶(AST)水平;采用酶联免疫吸附剂测定(ELISA)法检测细胞因子白介素-10(IL-10)、白介素-6(IL-6)及肿瘤坏死因子(TNF-α)水平;取肝脏组织进行HE染色,观察组织病理改变;通过蛋白质印迹法(western blot,WB)方法观察肝脏组织内p-STAT3及cleaved caspase-3蛋白表达.结果 EEN组、EIN组制模后各时间点血清AMY、LPS和ALT和AST水平均低于同期SAP组,P<0.05.各时间点EIN组与同时间点EEN组相比血清TNF-α、IL-6水平下降,IL-10水平升高,P<0.05.与同期EEN组、SAP组相比,EIN组肝脏p-STAT3及cleaved caspase-3蛋白表达明显减弱(P<0.05).结论 早期免疫生态肠内营养改善SAP大鼠肝脏组织病理损伤,抑制肝脏组织p-STAT3激活,抑制cleaved caspase-3蛋白表达,具有肝功能保护作用.
Protective effect of early immune microecological enteral nutrition on liver function in rats with severe acute pancreatitis
Objective To investigate the protective effect of early immune microecological enteral nutrition on liver function in rats with severe acute pancreatitis(SAP).Methods One hundred and twenty healthy male SD rats were randomly divided in-to 4 groups:the normal control group(SO group),the severe acute pancreatitis model group(SAP group),the early enteral nu-trition group(EEN group),and the ecological immune nutrition group(EIN group).Each group was further divided into three sub-groups(n=10):12 h,24 h and48 h.Except for the normal control group,SAP model was prepared by retrograde pancre-atic bile duct injection with 5%sodium taurocholate in other groups.The abdominal aorta blood was collected to detect serum AMY,LPS,ALT and AST levels.Serum TNF-α,IL-6 and IL-10 levels were detected by ELISA.Pancreas and liver tissues were stained with HE and histological changes were observed.The protein expressions of p-STAT3 and cleaved caspase-3 in liver tis-sues were observed by western blotting.Results AMY,LPS,ALT and AST levels in the EEN group and the EIN group were lower than those in the SAP group at each time point after model making,with statistically significant differences(P<0.05).Compared with the EEN group at the same time point,serum TNF-α and IL-6 levels in the EIN group at each time point were sig-nificantly decreased,while IL-10 levels were significantly increased,with statistically significant differences(P<0.05).Com-pared with the EEN group and the SAP group,liver p-STAT3 and cleaved caspase-3 protein expression were significantly reduced in the EIN group,with statistically significant differences(P<0.05).Conclusion Early use of immune microecological enteral nutrition intervention can significantly improve pathological damage of pancreas and liver,significantly inhibit activation of p-STAT3 in liver tissue,inhibit expression of cleaved caspase-3 protein,and have a protective effect on liver function.
