慢性疲劳综合征中医证候及证素特点的文献评析

目的通过对慢性疲劳综合征近20年文献的研究，探讨其中医证候的临床分布规律，并在此基础上进行证候要素的提取，总结其分布规律。方法通过计算机检索和手工检索国内有关中医药辨治慢性疲劳综合征的文献，应用EpiData 3.1建立数据库，对证候及证候要素进行频次分析。结果临床最常见的证候类型主要是心脾两虚证、肝郁脾虚证、肝肾阴虚证、肝气郁结证、脾胃气虚证。病位依次为脾、肝、肾、心。临床病机特点以正虚为主，兼有虚实夹杂，正虚以气虚、血虚、阴虚为主；邪实以气滞、痰湿、瘀血为主。结论从证候要素入手进行中医证候的研究能够更好地统一、规范临床辨证，文献分析结果可为进一步研究提供参考。
