          摘  要  目的  基于铁死亡角度探讨膈下逐瘀汤干预代谢相关脂肪性肝病(MAFLD)的潜在作用机制。方法  借助网络药理学方
          法,筛选膈下逐瘀汤干预MAFLD铁死亡的中心靶点,并进行基因本体、京都基因和基因组数据库富集分析和分子对接。将发育
          正常的受精后3 d的斑马鱼幼鱼随机分为对照组、模型组(5 mmol/L硫代乙酰胺)、异甘草酸镁组(阳性对照,5 mg/mL)和膈下逐瘀
          汤低、中、高质量浓度组(20、40、80 μg/mL,以生药量计),培养72 h后检测其体内丙氨酸转氨酶(ALT)、天冬氨酸转氨酶(AST)、总
                                                                                                 2+
          胆固醇(TC)、甘油三酯(TG)、丙二醛(MDA)、超氧化物歧化酶(SOD)、谷胱甘肽(GSH)、活性氧(ROS)、铁离子(Fe )含量,观察其
          肝组织细胞结构和肝脏脂肪变性情况,检测其沉默信息调节因子1(SIRT1)、核转录因子红系2相关因子2(Nrf2)、谷胱甘肽过氧化
          物酶 4(GPX4)蛋白的表达水平。结果  膈下逐瘀汤潜在活性成分作用于 MAFLD 铁死亡的 8 个中心靶点包括肿瘤蛋白 p53、
          SIRT1、Nrf2等;其富集于RNA聚合酶Ⅱ启动子转录的正/负向调控等生物过程,细胞核、细胞质等细胞成分,蛋白质结合等分子功
          能,以及铁死亡、癌症途径等信号通路,且可与主要活性成分紧密结合。与模型组比较,各药物组斑马鱼幼鱼体内ALT、AST、TC、
                        2+
          TG、MDA、ROS、Fe 含量均显著降低,SOD、GSH含量均显著升高(P<0.05),其肝组织细胞病理损伤情况均有所改善、肝脏脂质蓄
          积均有所减少,SIRT1、Nrf2、GPX4蛋白的表达均显著上调(P<0.05)。结论  膈下逐瘀汤可调节MAFLD模型斑马鱼幼鱼的脂质
          代谢,改善其氧化应激水平,维持其体内Fe 稳态,抑制其铁死亡进程,上述作用可能与激活SIRT1/Nrf2/GPX4轴有关。

          ABSTRACT   OBJECTIVE  To  explore  the  potential  mechanism  of  action  of  Gexia  zhuyu  decoction  in  the  intervention  of
          metabolic-associated  fatty  liver  disease (MAFLD)  based  on  ferroptosis.  METHODS  With  the  help  of  network  pharmacology,  the
          central  targets  of  Gexia  zhuyu  decoction  intervening  in  ferroptosis  of  MAFLD  were  screened,  then  gene  ontology,  Kyoto
          Encyclopedia  Gene  and  Genomes  enrichment  analysis  and  molecular  docking  were  performed.  Juvenile  zebrafish  with  normal
          development  at  3  d  post-fertilization  were  randomly  divided  into  control  group,  model  group (5  mmol/L  thioacetamide),
          magnesium  isoglycyrrhizinate  group (positive  control,  5  mg/mL),  and  Gexia  zhuyu  decoction  low- ,  medium-  and  high-
          concentration groups (20, 40, 80 μg/mL, calculated by crude drugs). After cultured for 72 h, the contents of alanine transaminase
         (ALT),  aspartate  transaminase (AST),  total  cholesterol (TC),  triglyceride (TG),  malondialdehyde (MDA),  superoxide
          dismutase (SOD), glutathione (GSH), reactive oxygen species (ROS) and Fe  were determined; the cellular structure of the liver
                                                                     2+
          tissues  and  hepatic  steatosis  were  observed;  the  protein  expression  of  silence  information  regulator  1 (SIRT1),  nuclear  factor-
          erythroid 2-related factor 2 (Nrf2) and glutathione peroxidase 4 (GPX4) were detected. RESULTS The central targets of potential
          active  ingredients  of  Gexia  zhuyu  decoction  that  act  on  ferroptosis  in  MAFLD  included  tumor  proteins  p53,  SIRT1,  Nrf2,  etc.,
          which  were  enriched  in  biological  processes  such  as  positive/negative  regulation  of  RNA  polymerase  Ⅱ  promoter  transcription,
          cellular  components  such  as  nucleus  and  cytoplasm,  molecular  functions  such  as  protein  binding,  as  well  as  signaling  pathways
                                                             such as ferroptosis and the cancer pathway, and they might be
