Methods 64 newly diagnosed ITP patients, including 25 male, 39 female. And the median age is 31 (18 ~ 70). It is randomly divided into (1) control group(31 cases): Prednison 1.0mg/kg·d: Starts to take it orally, and general course is 3-6 months. (2) experimental group (33 cases) : rituxan 100 mg/w, intravenous drip, stay on four times; at the same time giving adrenal glucocorticoid treatment which usage is in accord with the control group. Then observe and compare of the long-term curative effect, short-term curative effect and the adverse reactions of the two groups of patients. Consequence In the 4th week after treatment, the OR rate of patients in 2 groups is 81.28% to 67.74% respectively, P 0.05; in the 3th month it is 66.67% to 41.94% respectively, P 0.05; in the 6th month it is 63.64% to 35.48% respectively, P 0.05; in the 12th month OR rate is 60.61% to 32.26% respectively, P 0.05. The difference of the OR rate in t
