          摘   要  目的  基于核因子E2相关因子(Nrf2)/血红素加氧酶1(HO-1)/醌氧化还原酶1(NQO1)通路,探讨大飞扬草外泌体纳米囊
          泡(Eh-ENVs)对对乙酰氨基酚(APAP)诱导肝损伤的改善作用及机制。方法  通过考察Eh-ENVs对RAW264.7和AML12细胞活
          力的影响,以及对正常小鼠血清肝、肾功能指标和肝、肺等组织病理形态学的影响,评价其安全性。构建脂多糖(1 μg/mL)诱导的
          RAW264.7 细胞炎症模型,考察 10、20 μg/mL Eh-ENVs 对模型细胞中炎症因子 mRNA 表达和活性氧(ROS)水平的影响,并考察
          RAW264.7 细胞对 Eh-ENVs 的摄取效率。构建 APAP 诱导的肝损伤小鼠模型,考察 4 mg/kg Eh-ENVs 对模型小鼠血清肝功能指
          标,肝组织病理形态学,肝组织中炎症因子mRNA表达、丙二醛(MDA)水平、超氧化物歧化酶(SOD)水平以及Nrf2/HO-1/NQO1通
          路相关 mRNA 及其蛋白表达的影响。结果  体外实验结果显示,Eh-ENVs 对 RAW264.7 和 AML12 细胞均无增殖抑制作用;Eh-
          ENVs可被RAW264.7细胞高效摄取,并能显著降低细胞中白细胞介素1β(IL-1β)、肿瘤坏死因子α(TNF-α)mRNA表达和ROS水
          平(P<0.05)。体内实验结果显示,4 mg/kg Eh-ENVs对正常小鼠无明显毒副作用;可显著降低模型小鼠血清中丙氨酸氨基转移酶
         (ALT)、天冬氨酸氨基转移酶(AST)水平(P<0.05),上调/升高肝组织中IL-10 mRNA以及Nrf2、HO-1、NQO1 mRNA及其蛋白表
          达和 SOD 水平(P<0.05),下调/降低肝组织中 TNF-α、IL-1β mRNA 表达和 MDA 水平(P<0.05)。结论  Eh-ENVs 可能通过激活
          Nrf2/HO-1/NQO1通路,抑制炎症反应并减轻氧化应激,进而改善APAP诱导的肝损伤。

          ABSTRACT    OBJECTIVE  To  investigate  the  ameliorative  effect  and  mechanism  of  Euphorbia  hirta  L. -derived  exosome-like
          nanovesicles(Eh-ENVs)  on  acetaminophen (APAP)-induced  liver  injury  based  on  the  nuclear  factor  erythroid  2  related  factor  2
         (Nrf2)/heme  oxygenase-1 (HO-1)/NAD(P)H:quinone  oxidoreductase  1 (NQO1)  pathway.  METHODS  The  safety  of  Eh-ENVs
          was  evaluated  by  examining  their  effects  on  the  viability  of  RAW264.7  and  AML12  cells,  as  well  as  serum  liver  and  kidney
          function  indicators  and  histopathology  of  liver,  lung,  and  other  tissues  in  normal  mice. A  lipopolysaccharide (1  μg/mL)-induced
          RAW264.7  cell  inflammation  model  was  constructed  to  investigate  the  effects  of  10  and  20  μg/mL  Eh-ENVs  on  the  mRNA
          expression of inflammatory factors and reactive oxygen species (ROS) level in model cells, and the uptake efficiency of Eh-ENVs
          by  RAW264.7  cells  was  also  examined. An APAP-induced  liver  injury  mouse  model  was  established  to  investigate  the  effects  of  4
          mg/kg  Eh-ENVs  on  serum  liver  function  indicators,  liver  histopathology,  mRNA  expression  of  inflammatory  factors,
          malondialdehyde (MDA) level, superoxide dismutase (SOD) level, and mRNA and protein expressions related to the Nrf2/HO-1/
          NQO1  pathway  in  liver  tissue  of  model  mice. RESULTS  In  vitro  results  showed  that  Eh-ENVs  had  no  inhibitory  effect  on  the
                                                              proliferation  of  RAW264.7  and  AML12  cells;Eh-ENVs  could
