症状群落理论对中医辨证思维影响的探究

病机是疾病发生、发展、变化和转归的机制,症状是病机的外在表征,证候则是一组有内在联系的症状及其所蕴含病机的统一体。中医辨证诊断的本质是通过症状集合这一疾病的外在表现,推测和判断内隐的病机。"症状群落"概念,是指在同一病证中出现,具有共同病理机制,常相伴而生的几个症状共同组成的症状集合。症状群落具有生态特征,是内在病理机制的外部表征,几个症状群落共同构成具体证候的临床表现。疾病在一个阶段出现的若干症可以分别组合成若干个具有共同中医病理机制的症状群落,一种病机往往与某几个症状群落相联系。症状群落有更强的诊断指向性,对提高中医辨证诊断水平有积极影响,掌握并且熟练运用症状群落理论可以有效提高临床辨证诊断的正确率。

Effects of the Symptom Cluster Theory on TCM Dialectical Thinking

Pathogenesis is the mechanism of disease occurrence,development,change and outcome. Symptom is the external representation of the pathogenesis while syndrome is a unity of the inherent link between the symptom and the pathogenesis. The essence of the TCM syndrome differential diagnosis is to speculate and judge the pathogenesis through the external manifestations of the symptoms. The symptom cluster theory was the symptoms collection that appeared in the same condition,with common pathological mechanism,often accompanied by a cluster of symptoms. The symptom cluster has the ecological characteristics,is the external manifestations of pathological mechanism. Several symptom clusters constitute the clinical manifestations of the specific syndrome. Symptoms that occur in the certain stage of diseases can constitute several symptom clusters with common pathological mechanism respectively. A kind of pathogenesis is often associated with several certain symptoms. The symptom cluster has a higher diagnosis directionality which has positive effects on the improvement of clinical syndrome differential diagnosis level,learning and applying symptom cluster theory skillfully can improve the accuracy of clinical syndrome differential diagnosis effectively.
