焦虑症中医证候多元分析初步研究

Syndrome of Traditional Chinese Medicine of Anxiety with Multiple Factors Analysis

目的:探讨焦虑症的客观辨证方法。方法:对符合CCMD-3广泛性焦虑症诊断标准者,填写中医临床症状表,并采用多元统计方法分析焦虑症的中医症状、证型分布特征。结果:聚类分析将焦虑症的临床10余种证型简化为5种证型组合。5种证型组合中复合证候较多,以心脾两虚型最为多见,与临床观察实际基本符合。判别分析进一步显示了每组证型构成表征的权重和具有鉴别意义的表征,为实现客观辨证提供了依据。然而,聚类分析所得到的证型分类与传统中医辨证分型之间也存在一定的差异。结论:多元分析方法是焦虑症实现辨证客观化的途径之一。但聚类分析所得到的证型如何实现与传统临床治疗经验的对接有待进一步探索。

Objective： Exploring the method of objective differentiation of Anxiety. Method： Patients of General Anxiety need to fill a form about the symptoms of Traditional Chinese Medicine, and then analyze the distributive characteristics of the symptoms and the syndromes by clustered and discriminant analysis. Result： Clustered analysis method let more than 10 syndromes became 5 assemblage syndromes which are most complex syndrome. The most common syndrome is deficiency heart and spleen which accord with the clinical observation. Discriminant shows that the strength of every symptom which consist of the syndrome, and that distinguish symptoms. It may be the base for objective differentiation of TCM. But it is obviously different from the result of clustered analysis and traditional differentiation. Conclusion： The multiple factors analysis method may materialize the way of the objective differentiation of TCM. On the other hand, the way to inherited the traditional experience for the syndromes basis on the multiple analysis still need to be explored.
