Abstract: Objective To explore the correlation among psoriasis patients’ age of onset, age, recurrence frequencies , disease course and traditional Chinese medicine(TCM) syndromes. Methods Based on the clinical epidemiologic mass survey, the study was carried out by means of a status survey, multi-center and large-sample research. The data base was set up by EPIINFO 6.0. The SPSS was used to do the statistical analyses in 2 675 cases of psoriasis vulgaris to study the correlations among patients’ age of onset, age, recurrence frequencies, disease course and TCM syndromes. Results The TCM syndromes in psoriasis vulgaris mainly include the blood heat syndrome 1 489(55.7%), blood dryness syndrome 593(22.2%), and blood stasis syndrome 323(12.1%). The sequences from young to old in age of onset and age are blood heat syndrome, blood dryness syndrome, and blood stasis syndrome(P<0.01). Blood heat’s recurrence frequencies is the least among the 3 syndromes(P<0.01). The sequences from short to long of disease courses are blood heat syndrome, blood dryness syndrome, and blood stasis syndrome(P<0.01). Conclusion The blood heat syndrome, blood dryness syndrome, and blood stasis syndrome are the main syndromes of psoriasis vulgaris. There are not only onset sequences but also different degrees of treatment difficulty among the 3 TCM syndromes.
