支气管哮喘患者中医四诊信息调查及验证性因子分析

目的:收集支气管哮喘患者中医四诊信息,进行证候分类.方法:随机调查430例支气管哮喘患者,详细记录四诊信息,用Amos软件建立数据模型,进行验证性因子分析(confirmatory factor analysis,CFA).结果:行四因子、五因子及六因子分析,其中六因子分析结果与临床实际相一致.结论:按六因子分析结果排序,以标准回归系数0.4作为主次证界值,将支气管哮喘分为寒饮伏肺证、痰热蕴肺证、风痰阻肺证、肺肾气虚证及脾气不足证等5大类证候.

Investigation and confirmatory factor analysis of information collected with the four diagnostic methods in patients with bronchial asthma

Objective: To investigate the information acquired through the four diagnostic methods of traditional Chinese medicine in patients with bronchial asthma, and to classify the syndrome types. Methods: Four hundred and thirty patients with bronchial asthma were randomly investigated. The information acquired through the four diagnostic methods was recorded and the database was established by Amos software, and then the data were analyzed by confirmatory factor analysis (CFA). Results: After analyzing the data with 4 factors, 5 factors and 6 factors, we found that the results of CFA with 6 factors were in accordance with clinical practical experience. Conclusion: According to the results of CFA with 6 factors and with the standard regression coefficient 0.4 as primary and secondary critical points, the syndromes in patients with bronchial asthma can be classified into 5 types, which are syndromes of cold fluid retained in lung, phlegm-heat obstructing lung, wind-phlegm blocking lung, qi deficiency of lung and kidney and qi deficiency of spleen.
