Objective To investigate the effects of intravascular low energy laser irradiation on blood (ILIB) on renal function of the patients with early diabetic nephropathy. Methods Fifteen patients with type 2 diabetes mellitus complicated with early diabetic nephropathy, were treated with ILIB in addition to the conventional drugs, and observed the maximal time(Tmax)of renal concentration,the variation of 10 minutes residual rate and 15 minutes residual rate, respectively, by using the SPECT of isotone 99mTc-EC before and after ILIB treatment, and compared the results obtained before and after ILIB treatment. Results There were significant differences with regard to the 10 minutes residual rate (both the left and right kidney,P0.05). Conclusion ILIB could improve the excretion and secretion function of renal tubule in patients with the type 2 diabetes mellitus complicated with early diabetic nephropathy, and ILIB could be used as an effectively therapeutic method for patients with early diabetic nephropathy.

DPN ( Diabetes Peripheral Neuropathy) is one of the most important complications of type 1 and type 2 diabetes, with high rate of mutilation, intractable character, and complicated etiological factors.. Therefore, it is necessary to replicate the animal model with typical characteristics of human DPN. This article reviewed the establishment of DPN animal model in recent years.
