摘要: 目的 探讨粪菌移植干预对非酒精性脂肪性肝病(NAFLD)动物肠道菌群的影响。方法 将32 只大鼠随机分为ABCD四组,其中3组用混合抗生素抑菌1周后,予以高脂饮食建立NAFLD模型,再分别给予NAFLD患者粪菌或和正常人粪菌移植,检测肠粘膜组织16sDNA菌群。结果 模型组Rodentibacter菌群丰度较对照组升高,在NAFLD粪菌移植组升高更显著,而在正常人粪菌移植组则有所下降。结论 NAFLD粪菌群可能是肝脏脂肪变性的一个危险因素,而应用健康人粪菌移植可以改善高脂饮食大鼠脂肪肝病变。

Abstract: Objective The aim of this study was to investigate the effects of fecal bacteria transplantation (FBT) on microflora in rats with high-fat-induced liver steatosis. Methods 32 rats were randomly divided into group A, B, C and D. The non-alcoholic fatty liver disease (NAFLD) model was established by high-fat feeding, and fecal bacteria transplantation from patients with NAFLD and healthy persons were performed. The 16 sDNA flora of intestinal mucosal tissue were analyzed. Results The content of Rodentibacter in the model group was increased as compared to that in the control, but it increased more greatly in the rats with FBT from NAFLD, and it decreased greatly in rats with FBT from healthy persons. Conclusion The bacteria flora of patients with NAFLD might be a risk factor for hepatic steatosis, and FBT by using healthy person’s feces might alleviate the liver steatosis.
