Methods: Seventy-one NS patients applying prednisone and initiating dose reducing stage were randomized into trial group and control group. On the basis of conventional prednisone dose reduction of both groups, the trial group was given additionally XST, and the treatment course ended with the reduction to maintenance dose. In the course of observation, those who did not comply with the criteria of observation were excluded. Before and after the dose reduction, TCM syndrome scoring, 24 hrs urinary protein amount, blood β2-microglobulin (β2-MG), urinary β2-MG, blood fibrinogen (Fbg), plasma prothrombin time (PT), blood lipid, etc. were observed. Results: The trial group of XST could obviously lower their urinary protein amount and blood lipid level (P<0.05 or P<0.01), markedly improve the blood coagulation parameters (P<0.01), improve the TCM syndrome and CS induced adverse reaction (P<0.05 or P<0.01), also obviously reduced the recurrence rate of NS (P<0.05). Conclusion: XST could obviously improve the clinical symptoms and renal impairment parameters in NS patients during CS dose reduction stage, improve the CS induced adverse reaction and prevent the recurrence of NS.展开更多
