基于因子分析法探讨顽固性感冒后咳嗽中医证候分布规律

STUDY ON DISTRIBUTION REGULARITIES OF TRADITIONAL CHINESE MEDICINE SYNDROMES IN REFRACTORY POSTINFECTIOUS COUGH BASED ON FACTOR ANALYSIS METHOD

目的:探讨顽固性感冒后咳嗽中医证候分布规律,为该病的辨证论治提供依据。方法:多中心收集319例顽固性感冒后咳嗽患者,采用因子分析法对其症状信息进行中医证候非线性降维研究。结果:在提取的4个公因子中,F1代表气滞痰郁证,F2代表肺脾两虚证,F3代表心肾阴虚证,F4代表风燥犯肺证,并且初步建立了各个证候的辨证要点。结论:采用因子分析法对顽固性感冒后咳嗽进行证候分布规律研究是可行的,可为本病的辨证论治提供依据。

Objective: To explore the distribution regularities of traditional Chinese medicine syndromes of refractory postinfectious cough,and to provide Objective evidence for syndrome differentiation and treatment in clinic. Methods: Multicenter research on TCM syndromes in 319 cases of refractory postinfectious cough was done with thenonlinear dimension reduction by factor analysis. Results: There were 4 extracted factors in factor analysis: F1 was qi stagnation and phlegm stasis , F2 was deficiency of both lung and spleen, F3 was yin deficiency of heart and kidney, F4 was attacking on the lung by wind and dry. The key point of diagnostic criteria for TCM syndromes were preliminarily and respectively established. Conclusion: It is feasible that factor analysis was applied to study on distribution regularities of traditional Chinese medicine syndromes of refractory postinfectious cough, and it was considered that the result can provide Objective evidence for syndrome differentiation and treatment.
