[Clinical study on effect of tongluo capsule in treating diabetic nephropathy caused chronic renal failure].

To observe the therapeutic effect of Tongluo capsule (TLC) in treating diabetic nephropathy (DN) complicated chronic renal failure (CRF), and to explore its mechanism preliminarily.Ninety-seven patients with DN-CRF were randomly divided into the TCM group (n = 50) and the WM group (n = 47) to observe the changes of urinary protein per 24 hrs (UP/24h), renal function, creatinine (Cr), blood urea nitrogen (BUN), blood lipids (TG, TC, HDL-C, LDL-C) and serum transforming growth factor-beta1 (TGF-beta1) before and after treatment.After 6 months of treatment, levels of UP/24h, Cr, BUN and TGF-beta1 significantly lowered in both groups (P<0.01), and a better effect was showed in the TCM group in aspects of lowering Cr, BUN and TGF-beta1 (P<0.01). Besides, TLC also showed effect in lowering the serum lipid parameters (P<0.05 or P<0.01).Effect of TLC in treating DN-CRF might be through lowering the levels of blood lipids and serum TGF-beta1.
