摘要 非酒精性脂肪性肝病(nonalcoholic fatty liver disease,NAFLD)是一种无过量饮酒史的以肝实质细胞脂肪变性和脂肪贮积为特征的临床病理综合征,其在以前曾被认为是良性疾病,但是越来越多的研究表明它可以进一步发展为肝纤维化、甚至肝硬化^[1-3],甚至有文献显示其有进展到原发性肝癌的趋势^[4]。目前的研究认为NAFLD的发病机制可能与胰岛素抵抗、瘦素抵抗、脂质过氧化、炎症反应等因素相关。但是随着研究的进一步深入,陆续有报道认为肠道发生病变如肠细菌过度生长(intesdnal bacterial overgrowth.IBO)、细菌移位、肠黏膜通透性改变等所产生的肠源性内毒素血症(in—tesfinal endotoxemia,IEIM)白始至终起着关键作用。而且,NAFLD进展到一定阶段后,又会反过来影响肠道微生态的平衡.最终两者形成恶性循环,相互影响。本文就NAFLD与肠道微生态失衡的关系作一综述。
