【摘要】：目的:基于主成分分析和因子分析的方法探索功能性腹胀病中医证候特征。方法:纳入功能性腹胀患者共300例,用Excel建立临床资料数据库,将患者性别、年龄及中医症状积分等录入并保存,核实无误后导入SPSS统计软件进行主成分分析和因子分析。结果:用主成分分析法提取具有相对独立性且特征值均在1.0以上的11个主成分,累积贡献率为67.944%。通过因子旋转法提取11个因子组合结合中医理论分析得出功能性腹胀证候:实证:肝胃不和(13.541%)、肠道实热(9.922%)、肝脾不和(6.558%)、胃火炽盛(6.108%)、胃肠湿热(5.393%)、肝胃郁热(4.689%)、痰湿中阻(4.251%)、脾胃不和(3.666%);虚证:脾胃虚寒(7.139%);虚实夹杂证:肝郁脾虚(3.484%)、脾虚湿盛(3.194%)。结论:运用主成分分析和因子分析法可更为客观准确的分析功能性腹胀中医证候特征。
[Abstract]:Objective: to explore the TCM syndrome characteristics of functional abdominal distension based on principal component analysis and factor analysis. Methods: a total of 300 patients with functional abdominal distension were included. The data base of clinical data was established by Excel. The patients' gender, age and TCM symptom score were recorded and preserved. After checking, the data were imported into SPSS statistical software for principal component analysis and factor analysis. Results: eleven principal components with relative independence and their eigenvalues above 1.0 were extracted by principal component analysis, and the cumulative contribution rate was 67.944. The functional abdominal distension syndrome was obtained by extracting 11 factors by the method of factor rotation combined with the analysis of TCM theory. The symptoms were as follows: disharmony of liver and stomach (13.541%), solid heat of intestinal tract (9.922%), disharmony of liver and spleen (6.558%). The stomach fire was hot (6.108%), the gastrointestinal damp-heat (5.393%), the liver and stomach stagnation heat (4.689%), the phlegm dampness obstruction (4.251%), the spleen and stomach disharmony (3.666%); Deficiency syndrome: spleen and stomach deficiency cold (7.139%), deficiency and deficiency syndrome: liver stagnation and spleen deficiency (3.484%), spleen deficiency dampness (3.194%). Conclusion: principal component analysis and factor analysis can be used to analyze TCM syndrome characteristics of functional abdominal distension more objectively and accurately.
