The result indicated that ZXTMN group excelled the western medicine in the aspects of ameliorating symptom and hemodynamics, adjusting sugar and lipid metabolism, and reducing urine albumin and pltaelet adhesiveness and aggreagtion. The mechanism, which ZXTMN prescription could protect renal function, probably was (1) decreasing the level of sugar and glycosylated ferrohemoglobin;(2) decreasing AR activity of erythrocyte, improving SDH activity of erythrocyte, reducing accumulation of sorbitol in the erythrocyte, thus ameliorating the polyol metabolism;(3) accommodating lipid metabolism;(4) ameliorating coagulation, gathering, thick and mucosity of patient blood.
