Objective To investigate the influence of Fasudil on oxidative stress in patients with early-stage diabetic nephropathy. Methods 48 patients with earl-stage diabetic nephopathy were randomly divided into control group treated with Alpha-lipoic acid and treametn group with Fasudil. All patients were under strict control of blood glucose. Changes in the levels of serum cysc, urinal mALB and 8-OHdG were observed after two weeks treatment were compared between the two groups. Results Compared to pre-treatment, the content of serum cysc, urinal mALB and 8-OHdG were significantly decreased in both groups after treatment. There was no significant difference in the content of urine mAlb , CTGF and MCP-1 between the two groups before and after treatment (P > 0.05). Conclusion Fasudil may protect kidney through a mechanism by which the level of 8-OHdG in kidney is decreased and oxidative stress is alleviated.
