摘要代谢相关脂肪性肝病(metabolic associated fatty liver disease，MAFLD)是由一种胰岛素抵抗和遗传易感密切相关的代谢功能障碍所引发的脂肪性肝病，也称非酒精性脂肪性肝病(nonalcoholic fatty liver disease，NAFLD)。慢性丙型病毒性肝炎(chronic hepatitis C，CHC)是一种全球性分布的由丙型肝炎病毒(hepatitis C virus，HCV)感染引起的目前可治愈的病毒性肝炎。MAFLD如合并CHC，CHC可导致胰岛素抵抗以及增加肝细胞氧化应激加速肝细胞脂肪变性，影响MAFLD的治疗效果。

abstractsMetabolic related fatty liver disease(MAFLD) is a kind of fatty liver disease caused by metabolic dysfunction closely related to insulin resistance and genetic susceptibility, also known as nonalcoholic fatty liver disease (NAFLD). Chronic hepatitis C (CHC) is a worldwide curable viral hepatitis caused by hepatitis C virus (HCV) infection.If MAFLD is combined with CHC, CHC can lead to insulin resistance, increase the oxidative stress of hepatocytes, accelerate the steatosis of hepatocytes, and affect the therapeutic effect of MAFLD.
