        摘   要   目的:研究葫芦茶苷对四氯化碳(CCl4 )致肝纤维化模型小鼠的保护作用,并探讨其可能机制。方法:将昆明种小鼠随机
        分为正常组、模型组、秋水仙碱组(阳性对照,0.2 mg/kg)和葫芦茶苷低、中、高剂量组(3、6、12 mg/kg),每组10只。除正常组小鼠腹
        腔注射橄榄油外,其余各组小鼠均腹腔注射10%CCl4橄榄油溶液(5 mL/kg)以复制肝纤维化模型,每周2次,连续8周。自第3周
        起,各给药组小鼠灌胃相应药物,正常组和模型组小鼠均灌胃等体积2%羧甲基纤维素钠溶液,每日1次,连续6周。采用酶联免
        疫吸附测定法检测各组小鼠血清中丙氨酸转氨酶(ALT)、天冬氨酸转氨酶(AST)、透明质酸(HA)、白细胞介素6(IL-6)的含量;采
        用分光光度法、逆转录-聚合酶链反应法、Western blotting法分别检测其肝组织中羟脯氨酸(Hyp)、超氧化物歧化酶(SOD)、丙二醛
        (MDA)、谷胱甘肽过氧化物酶(GSH-Px)的含量,Ⅰ型胶原(Col-Ⅰ)、金属蛋白酶组织抑制因子1(TIMP-1)、TIMP-2 mRNA以及基
        质金属酶 2(MMP-2)、转化生长因子β 1 (TGF-β 1 )蛋白的表达情况。结果:与正常组比较,模型组小鼠 ALT、AST、HA、IL-6、MDA、
        Hyp含量,Col-Ⅰ、TIMP-1、TIMP-2 mRNA以及MMP-2、TGF-β 1蛋白的表达水平均显著升高,SOD、GSH-Px含量均显著降低(P<
        0.01)。与模型组比较,各给药组小鼠ALT、AST、HA、IL-6、MDA、Hyp含量,Col-Ⅰ、TIMP-1、TIMP-2 mRNA以及MMP-2、TGF-β 1
        蛋白的表达水平均显著降低,SOD、GSH-Px含量均显著升高(P<0.05或P<0.01)。结论:葫芦茶苷对肝纤维化模型小鼠具有肝保
        护和肝纤维化抑制的作用,其机制可能与抑制脂质过氧化和胶原蛋白合成,下调 Col-Ⅰ、TIMP-1、TIMP-2 mRNA 以及 MMP-2、
        TGF-β1蛋白的表达等有关。

        ABSTRACT    OBJECTIVE:To study the protective effect of tadehaginoside(TA)on liver fibrosis model mice induced by carbon
        tetrachloride(CCl4 ),and to investigate its mechanism. METHODS:Kunming mice were randomly divided into normal group,
        model group,colchicines group(positive control,0.2 mg/kg),TA low-dose,medium-dose and high-dose groups(3,6,12
        mg/kg),with 10 mice in each group. Those groups were intraperitoneally injected with 10% CCl4-olive oil solution(5 mL/kg)to
        induce liver fibrosis model twice a week,for consecutive 8 weeks;except that,the normal group was intraperitoneally injected
        with olive oil. From 3rd week,the mice in each administration groups were given relevant medicine intragastrically,normal group
        and model group were given constant volume 2% sodium carboxymethylcellulose solution intragastrically,once a day,for
        consecutive 6 weeks. The contents of ALT,AST,HA and IL-6 in serum of mice were tested by ELISA. The contents of Hyp,
