Abstract: | Objective:To explore the application of factor analysis and logistic regression analysis in the study of traditional Chinese medicine(TCM) syndromes of ulcerative colitis,and to provide a scientific basis for the classification of ulcerative colitis syndrome and the development of diagnostic criteria. Methods:A self-made"ulcerative colitis TCM syndrome epidemiology questionnaire" was applied,and 441 cases of ulcerative colitis were collected and analyzed by factor analysis and cluster analysis method. Results:Using the method of factor analysis,the basic TCM syndromes of ulcerative colitis determined were qi deficiency of spleen and stomach,damp heat in large intestine,yang deficiency in spleen and kidney,liver stagnation and spleen deficiency syndrome,yin deficiency and intestinal dryness,and blood stasis in intestinal collaterals. Multiple logistic regression analysis were applied to obtain the symptom qualification index for ulcerative colitis. Conclusion:Multivariate statistical methods of factor analysis and logistic regression analysis can be used for the classification and quantitative diagnosis of ulcerative colitis,and it can provide a new method to study the syndrome diagnosis standard of this disease. |
