非酒精性脂肪性肝病(NAFLD)是一种代谢应激性肝损伤,已成为我国乃至全世界最常见的慢性肝病之一。因此,NAFLD的发生发展过程及其防治都越来越受到人们的重视,而肠道微生态特别是肠道菌群发生紊乱就是导致NAFLD的重要因素之一。NAFLD中...非酒精性脂肪性肝病(NAFLD)是一种代谢应激性肝损伤,已成为我国乃至全世界最常见的慢性肝病之一。因此,NAFLD的发生发展过程及其防治都越来越受到人们的重视,而肠道微生态特别是肠道菌群发生紊乱就是导致NAFLD的重要因素之一。NAFLD中医病证溯源、病因病机与脾胃升降失调相关,NAFLD治疗获益有赖脾胃升降。肠道是中医脾胃实现功能的主要部位,肠道菌群是饮食影响宿主代谢状态的调节因子,符合中医学脾胃升降原理的生物学内涵。脾胃气机升降失常所表现的症状与肠道菌群失调时表现的症状具有一致性,故肠道菌群与中医脾胃升降有着密切联系。该文基于现代肠道微生态系统阐述了从中医脾胃升降关系论治NAFLD的理论基础,并据此提出了NAFLD的组方用药思路,主要包括健脾益气升清、行气和胃降浊、化痰活血消积,突出脾胃升降与肠道微生态协调在NAFLD论治中的主导作用;疏肝理气、宣降肺气、升清降浊、温肾助阳,顾及NAFLD发病协同因素,助力脾胃升降,从肠道微生态靶点考量治疗效应;中药保留灌肠激活大肠传导功能而助力胃气通降、协调脾胃气机升降,结合肠道菌群及其代谢的理论,从16s r DNA基因路径关注中药肠道给药途径干预NAFLD的肠道微生态机制。随着肠道菌群研究领域的深入推进,其与脾胃升降和NAFLD的关系将进一步揭示,既承接了我国从古至今运用脾胃升降理论治疗肝病的悠久历史,也将拓展调节肠道微生态(肠道菌群)治疗NAFLD的新视野。展开更多
