Objective To investigate the relationship between renal vascular resistance index( RI) and serum Apelin level in type 2 diabetic mellitus ( T2DM )?Methods Seventeen cases newly diagnosed T2DM patients with RI increased but without microalbuminuraia in Minhang Hospital Affiliated to Fudan University from December 2011 to December 2014 were selected as observation group,17 newly diagnosed T2DM patients with RI normal during the same period were selected as control group?Fasting plasma glucose(FPG),glycosylated hemoglobin A1C(HbAlC),blood lipids and fasting insulin(FINS),hepatic functional and renal function were tested in all the subjects?Serum Apelin level was detected by enzyme?linked immunosorbent assay?Results Compared with control group,serum Apelin level was significantly higher in observation group((179?2±122?4)μg/L vs?(56?7±50?6) μg/L,t=3?814,P<0?05)?Partial correlation analysis showed that the RI was positive correlated with Apelin ( r= 0?364, P= 0?040 )?Conclusion The serum Apelin levels elevated in newly diagnosed T2DM patients with RI increased, and RI is positively correlated with Apelin, which indicate that Apelin play an important role in the pathophysiology of early renal damage in patients with TsDM.
