          摘  要  目的  研究护肝布祖热方(HBF)对大鼠肝内胆汁淤积性肝损伤的影响及潜在机制。方法  将大鼠随机分为对照组(con‐
          trol组)、模型组(model组)、熊去氧胆酸(UDCA)组(阳性对照,60 mg/kg)和HBF低、中、高剂量组(HBF-L、HBF-M、HBF-H组,0.4、
          0.8、1.6 g/kg),每组6只。各药物组大鼠每天灌胃相应药液1次,连续7 d;control组和model组大鼠灌胃等体积水。实验第5天,除
          control组外,其余各组大鼠均单次灌胃α-异硫氰酸萘酯橄榄油溶液(100 mg/kg)建模。造模48 h后,检测大鼠血清中肝功能指标
         (天冬氨酸转氨酶、丙氨酸转氨酶、碱性磷酸酶、总胆汁酸、总胆红素、直接胆红素)含量和氧化应激指标[丙二醛(MDA)、谷胱甘肽

         (GSH)、超氧化物歧化酶]水平,观察肝组织病理形态变化,检测肝组织中炎症相关因子[肿瘤坏死因子α(TNF-α)和白细胞介素1β
         (IL-1β)]和法尼酯X受体(FXR)信号通路相关因子[FXR、小异源二聚体伴侣受体(SHP)、多药耐药蛋白2(MRP2)、胆盐输出泵转
          运蛋白(BSEP)、钠离子依赖性牛磺胆酸共转运蛋白(NTCP)、有机阴离子转运多肽 2(OATP2)和胆固醇 7α 羟化酶(CYP7A1)]
          mRNA,以及FXR信号通路相关蛋白(FXR、MRP2、BSEP、NTCP)和核因子κB p65(NF-κB p65)蛋白的表达情况。结果  与model
          组比较,HBF-H组大鼠血清中上述肝功能指标含量和MDA水平,肝组织中上述炎症相关因子mRNA、CYP7A1 mRNA的表达水
          平以及NF-κB p65蛋白的相对表达量均显著降低,血清中GSH水平和肝组织中FXR、SHP、MRP2、BSEP、NTCP、OATP2 mRNA的
          表达水平以及 FXR、MRP2、BSEP、NTCP 蛋白的相对表达量均显著升高(P<0.05 或 P<0.01),肝组织病理改变明显好转;HBF-L
          组、HBF-M组、UDCA组大鼠均只有部分指标显著逆转(P<0.05或P<0.01)。结论  HBF可预防大鼠肝内胆汁淤积性肝损伤,此
          作用可能与激活FXR信号通路、减轻炎症和氧化应激有关。

          ABSTRACT   OBJECTIVE  To  study  the  effects  of  Hugan  buzure  formula (HBF)  on  intrahepatic  cholestatic  liver  injury  in  rats
          and  its  potential  mechanism.  METHODS  Rats  were  randomly  divided  into  control  group,  model  group,  ursodeoxycholic  acid
         (UDCA)  group (positive  control,  60  mg/kg )  and  HBF  low-dose,  middle-dose  and  high-dose  groups (HBF-L,  HBF-M,  HBF-H
          groups,  0.4,  0.8,  1.6  g/kg ),  with  6  rats  in  each  group. The  rats  in  each  drug  group  were  given  the  corresponding  drug  solution
          intragastrically, once a day, for 7 consecutive days. The rats in the control group and the model group were given equal volumes of
          water intragastrically. On the 5th day, except for the control group, the rats in other groups were single intragastrically administered
          with  alpha-naphthyl  isothiocyanate  olive  oil  solution (100  mg/kg)  to  establish  the  model. After  48  h  of  modeling,  the  contents  of
          liver  function  indexes (aspartate  aminotransferase,  alanine  aminotransferase,  alkaline  phosphatase,  total  bile  acid,  total  bilirubin,
          direct  bilirubin)  and  oxidative  stress  indexes  [malondialdehyde (MDA),  glutathione (GSH),  superoxide  dismutase]  in  serum  of
          rats  were  detected;  the  pathological  changes  of  liver  tissue  were  observed.  The  mRNA  expressions  of  inflammation-related  factors
