Primary Outcome Measures:
  • To access the efficacy of TW compared to ARB in treatment of heavy proteinuria of diabetic nephropathy [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • To investigate the safety and tolerability of TW vs ARB. To access whether TW can delay the progression to ESRD or creatinine-doubling in diabetic nephropathy with heavy proteinuria. [ Time Frame: 6 months ] [ Designated as safety issue: Yes ]

Experimental: immunosuppressor
Valsartan,160mg/d,TW 120mg/d
Drug: TW
TW,120 mg/d

Detailed Description:

Diabetic nephropathy with heavy proteinuria have high risks of progressing to end stage renal disease. Though recent studies have shown that ACEI or ARB could reduce proteinuria of DN and slowed the progression to ESRD. But ARBs can only reduce proteinuria about 30%, so some patients still have heavy proteinuria,and then loss their renal function rapidly. So, to reduce the proteinuria of DN is a very important therapy target.

Tripterygium (TW) is a Chinese traditional patent drug, it can reduce proteinuria of chronic glomerular nephritis. So, we designed this randomized, prospective clinical trial to assess the efficacy and safety of TW versus ARB in the treatment of heavy proteinuria of DN.
