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

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

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
