  • 摘要:

    目的观察调肝理脾法对高脂高糖饲料诱导的非酒精性脂肪性肝病大鼠模型肠黏膜屏障Toll样受体(TLR) 4、occludin的影响。方法将50只SD雄性大鼠随机分为正常组、模型组、调肝理脾组、调肝组和理脾组,并用高脂高糖饲料喂养4周诱导大鼠非酒精性脂肪性肝病模型,观察各组肝脏脂肪变性程度,肝功能变化及肠黏膜紧密连接蛋白occludin、肠道上皮TLR4的表达情况。计量资料多组间比较采用单因素方差分析,进一步两两比较采用LSD-t检验。结果与正常组相比,模型组肝脏呈现脂肪变性;血清ALT、AST水平均显著升高(P值均<0. 05),肠黏膜上皮细胞紧密连接蛋白occludin的表达降低,肠道上皮TLR4表达增加。与模型组相比,各治疗组脂肪变性程度均有减轻; occludin的表达均有增加;肠道上皮TLR4表达均有降低。各治疗组中,调肝理脾组脂肪变性程度最轻;血清ALT、AST水平降低更显著,与模型组比较差异均有统计学意义(P值均<0. 05); occludin及TLR4的表达量变化更明显。结论调肝理脾法通过上调肠黏膜上皮细胞紧密连接蛋白occludin的表达,降低肠道TLR4的表...
