摘要

目的:研究枸杞多糖（lycium barbarum polysaccharide

LBP）对肝细胞（LO2）脂肪变性的防治作用及其机制。方法:油酸诱导建立非酒精性脂肪变性肝细胞（non-alcoholic fatty liver disease

NAFLD）模型

分为正常对照组、脂肪变模型组、LBP预防组、LBP治疗组。48 h后光镜下观察细胞内脂质累积情况

并检测细胞内谷氨酸氨基转移酶（alanine aminostransferase

ALT）、门冬氨酸氨基转移酶（aspartate aminostransferase

AST）、甘油三酯（triglyceride

TG）含量

及脂联素与抵抗素的基因及蛋白表达情况。结果:光镜下可见模型组肝细胞内较正常对照组有大量橘红色脂滴（P=0.000）

LBP预防组和治疗组与模型组比肝细胞内的脂滴明显减少（P=0.000、P=0.000）。LBP上调脂联素m RNA及蛋白表达（P=0.000、P=0.014）

抑制抵抗素m RNA及蛋白的表达（P=0.000、P=0.000）

降低肝细胞TG、ALT、AST（P=0.000、P=0.000、P=0.000）。结论:LBP可能通过上调脂联素m RNA及蛋白的表达

下调抵抗素m RNA及蛋白表达

从而有效防治NAFLD。

Abstract

Objective:To investigate the prevention and treatment effects and to preliminary discuss the action mechanisms of lycium barbarum polysaccharide(LBP)on hepatocyte steatosis model of hepatocyte in vitro. Methods:A model of non-alcoholic fatty liver disease(NAFLD)oleic acid-induced steatosis L-O2 strain hepatocyte(normal adult hepatocytes)was established. The model was divided into normal group

steatosis model group

prevention group and treatment group. The accumulation of lipid droplets in hepatocytes was observed under light microscopy after oil red-O staining after 48 h. The levels of alanine aminostransferase(ALT) aspartate aminostransferase(AST) triglyceride(TG) and the expression of m RNA and protein of adiponectin and resistin were detected.Results:Much more obvious orange lipid droplets in hepatocytes were found in model group after culture than in normal group(P=0.000). Lipid droplets decreased in prevention group and treatment group than in model group(P=0.000;P=0.000). The levels of ALT

AST and TG were decreased(P=0.000;P=0.000;P=0.000);the expressions of m RNA and protein of adiponectin were up-regulated(P=0.000;P=0.014)and the expressions of m RNA and protein of resistin were down-regulated(P=0.000;P=0.000). Conclusion:Induced by expression of m RNA and protein of adiponectin and resistin

NAFLD can be prevented and treated effectively by LBP.
