摘要: 目的:比较肉苁蓉苯乙醇总苷脂质体与未脂质化的肉苁蓉苯乙醇总苷原料药对肝纤维化大鼠肝脏的保护作用。方法:采用真空冷冻干燥法制备肉苁蓉苯乙醇总苷脂质体,测量其粒径、药物含量及包封率。将肝纤维化模型大鼠随机分组后给予相应受试物,比较空白对照组、模型组、空白脂质体组、肉苁蓉苯乙醇总苷原料药组、肉苁蓉苯乙醇总苷脂质体组各组大鼠的血清肝功能指标(AST、ALT)、肝脏纤维化指标(LN、H A、PC III、IV-C),Masson染色观察各组大鼠肝纤维化病变程度,实时荧光定量PCR (qPCR)检测大鼠肝组织Collagen Ⅰ和Collagen Ⅲ mRNA表达,Western blot法检测大鼠肝脏组织α-平滑肌肌动蛋白(α-sma)、Collagen Ⅰ蛋白表达。结果:肉苁蓉苯乙醇总苷脂质体组大鼠血清AST、ALT、LN、HA、PC III、IV-C等指标总体较肉苁蓉苯乙醇总苷原料药组及空白脂质体组大鼠下降(P < 0.01),肉苁蓉总苷脂质体组、肉苁蓉总苷原料药组大鼠肝组织中胶原纤维明显减少,其中肉苁蓉总苷脂质体组大鼠肝组织结构恢复良好,趋向正常。与肉苁蓉苯乙醇总苷原料药相比,肉苁蓉苯乙醇总苷脂质体可使大鼠肝脏组织Collagen Ⅰ、Collagen III mRNA表达下降(P < 0.01),α-sma、Collagen Ⅰ蛋白表达下降(P < 0.05)。结论:肉苁蓉苯乙醇总苷脂质体对模型大鼠的肝脏保护优于未脂质体化的肉苁蓉苯乙醇总苷原料药及空白脂质体,其机制可能与减少α-sma、Collagen Ⅰ合成有关。

Abstract: OBJECTIVE: Comparison of Cistanche phenylethanoid glycosides (CPhGs) liposomes and CPhGs on-BSA-induced-liver-fibrosis-in rats. METHODS: CPhGs liposomes were prepared by the vacuum freeze-drying method. Rats with liver fibrosis were randomly divided into different groups:the blank control,model,blank liposome,CPhGs and CPhGs liposome groups.Serum liver functions (AST,ALT) and liver fiber fibrosis (LN,HA,PC III and IV-C) of rats in each group were compared among the groups.Liver fibrosis was detected using the Masson staining procedure. Real-time fluorescent quantitative PCR (qPCR) was used to detect mRNA expression of α-sma、and collagen I. Western blot method was used to detect the protein expression of α-sma、Collagen I in the liver tissue of rats. RESULTS: The indexes of AST,ALT,LN,HA,PC III,IV-C in serum of rats in the CPhGs liposome group were lower than those in the CPhGs and the blank liposome groups. Compared with the CPhGs group,the CPhGs liposome group showed reduced mRNA expression of collagen I and collagen Ⅲ in the liver tissues (P < 0.01),and reduced protein expression of α-SMA and collagen I (P < 0.05). CONCLUSION: CPhGs liposomes showed better protection on the BSA-induced liver fibrosis in rats than the bulk drug and the blank liposomes. The mechanism may be related to the reduction of α-SMA and collagen I synthesis.
