          摘   要  目的  探讨23-乙酰泽泻醇B对急性酒精性肝损伤小鼠的保护作用及潜在机制。方法  将50只雄性昆明小鼠分为空白组、
          模型组和23-乙酰泽泻醇B低、中、高剂量组(10、20、40 mg/kg),每组10只。各组小鼠灌胃相应药液或生理盐水,每天1次,持续2
          周。于实验第15天,空白组小鼠灌胃生理盐水,其余4组小鼠灌胃12 mL/kg的白酒,共2次(间隔6 h)以建立急性酒精性肝损伤小
          鼠模型。实验期间,监测小鼠体重;于实验第16天,计算各组小鼠肝脏指数,检测其血清中丙氨酸转氨酶(ALT)、天冬氨酸转氨酶
         (AST)、总胆固醇(TC)、甘油三酯(TG)、丙二醛(MDA)、谷胱甘肽(GSH)水平,观察其肝组织病理形态并进行评分,检测肝组织中
          细胞色素P450 2E1(CYP2E1)、Kelch样环氧氯丙烷相关蛋白1(Keap1)、核转录因子红系2相关因子2(Nrf2)、NAD(P)H:醌氧化还
          原酶1(NQO1)蛋白的表达水平。结果  与模型组比较,23-乙酰泽泻醇B各剂量组小鼠体重均有不同程度恢复;肝组织炎症细胞浸
          润、脂肪空泡等病理改变均有不同程度改善;其肝脏指数,肝组织病理形态评分,血清ALT、AST、TC、TG、MDA水平,以及肝组织
          中CYP2E1、Keap1蛋白的表达水平均显著降低(P<0.05或P<0.01);血清GSH水平及肝组织中Nrf2(23-乙酰泽泻醇B低剂量组
          除外)、NQO1蛋白的表达水平均显著升高(P<0.05或P<0.01),且上述定量指标的变化呈剂量依赖趋势。结论  23-乙酰泽泻醇B
          能改善酒精急性暴露所引发的小鼠肝损伤,其机制可能与调控Keap1/Nrf2/NQO1信号通路以发挥抗氧化应激作用,同时改善肝脏
          脂质代谢有关。

          ABSTRACT    OBJECTIVE To investigate the protective effects and potential mechanism of alisol B 23-acetate on acute alcoholic
          liver  injury  in  mice.  METHODS  Fifty  male  Kunming  mice  were  divided  into  the  blank  group,  model  group,  and  alisol  B  23-
          acetate  low-,  medium-  and  high-dose  groups (10,  20,  40  mg/kg),  with  10  mice  in  each  group.  Each  group  was  given  relevant
          drug  solution  or  normal  saline  intragastrically,  once  a  day,  for  2  consecutive  weeks.  On  the  15th  day,  mice  in  the  blank  group
          were given normal saline intragastrically, while the other four groups were given 12 mL/kg white wine intragastrically, twice at six-
          hour  intervals,  to  establish  an  acute  alcoholic  liver  injury  model.  On  the  16th  day  of  the  experiment,  the  liver  indexes  of  mice  in
          each  group  were  calculated;  the  serum  levels  of  alanine  transaminase (ALT),  aspartate  transaminase (AST),  total  cholesterol
         (TC),  triglycerides (TG),  malondialdehyde (MDA)  and  glutathione (GSH)  were  also  determined.  The  histopathological
          morphology of their liver tissues was observed and scored. The protein expressions of cytochrome P450 2E1 (CYP2E1), Kelch-like
          ECH-associated  protein  1 (Keap1),  nuclear  factor  erythroid  2-related  factor  2 (Nrf2)  and  NAD(P)H:  quinone  oxidoreductase  1
         (NQO1) were measured in liver tissue. RESULTS Compared with model group, mice in each dosage group of alisol B 23-acetate
          showed  varying  degrees  of  recovery  in  body  weight,  along  with  improvements  in  pathological  changes  in  liver  tissues  such  as
          inflammatory cell infiltration and fatty vacuoles. Their liver indexes, histopathological scores of liver tissue, serum levels of ALT,
          AST, TC, TG and MDA, as well as the protein expressions of CYP2E1 and Keap1 in liver tissue, were all significantly decreased
         (P<0.05  or  P<0.01).  The  serum  GSH  levels  and  the  protein  expressions  of  Nrf2 (except  for  the  alisol  B  23-acetate  low-dose
                                                              group)  and  NQO1  in  liver  tissue  were  significantly  increased
