摘要
提出了一种基于熵的复杂系统分划方法用于中医证候诊断研究的新方法。根据临床流行病学调查获得400例血管内皮功能障碍患者的临床资料,收集相应的中医症状信息;以基于熵的复杂系统分划方法取得血管内皮功能障碍阴虚证的症状集合并确定其诊断阈值;最后从灵敏度、特异度、符合率3个方面对此诊断标准进行检验,结果证明该诊断标准有较好的诊断效能。说明基于熵的复杂系统分划方法适用于中医证候诊断的研究,为中医证候诊断的研究开辟了一条新途径。
A new approach（entropy-based partition method for complex system） for TCM syndrome diagdnosis was proposed.Firstly,a clinical epidemiology survey was carried out,400 patients of vascular endothelial dysfunction（ED） were chosen,and corresponding symptoms information was collected.Then the symptoms combination was reached according to the entropy-based partition method for complex system and the diagnostic threshold of ＂deficiency of Yin＂ in ED objectively was decided.Finally,an examination on this diagnostic criterion was conducted through three indexes：sensitivity,specificity and agreement rate.The result shows that the diagnostic criterion of ＂deficiency of Yin＂ in ED has a favorable diagnostic effect and the entropy-based partition method for complex system is suitable for study on the diagnosis of syndromes in TCM.It paves a new way for the research of syndromes in TCM.
