Objective:To explore characteristics of TCM syndrome differentiation of graft versus host disease（GVHD）after transplantation of the hemopoietic stem cell

so as to provide basis of clinical syndrome differentiation for further studying on treatment of this disease.Methods:62 cases of GVHD were grouped according to acute or chronic GVHD

and a total of 85 cases-times were investigated for TCM syndrome differentiation.Results:in 50 cases-times of acute GVHD

damp heat type accounted for 68% and 50% have jaundice due to hepatic injury;blood-heat and Yin-deficiency accounted for 32%

with more patients of more severe condition.In 35 cases times of chronic GVHD

damp heat type accounted for 25.7% with more patients companied with Yin- deficiency

blood stasis and Yin-deficiency rate accounted for 74.3%.Conclusion:Commonly-seen basic TCM syndrome types of GVHD are damp-heat and Yin-deficiency types.Damp-heat type was more common in acute GVHD and blood-heat and Yin- deficiency type was.more frequently found in severe patients;chronic GVHD manifest mainly as Yin-deficiency type and with exacerbation of condition and prolongation of disease course

Yin-deficiency type tends to increase.
