Abstract:
Objective To evaluate the significance of color Doppler ultrasound examination of renal blood flow combined with the detection of bone morphogenetic protein-7(BMP-7)in early diagnosis of type 2 diabetic nephropathy.Methods Blood BMP-7 level was tested in 90 patients with type 2 diabetic nephropathy and 30 controls,and parameters of renal blood flow were measured by color Doppler ultrasound examination.Blood BMP-7 level as well as resistant index(RI)of segmental renal artery(SRA)and interlobar renal artery(IRA),were compared between these two groups.Results Compared with controls,blood BMP-7 level gradually decreased with the aggravation of diabetic kidney damage(P<0.01).The peak systolic velocity(Vmax)and the end diastolic velocity(Vmin)of SRA and TRA were slowed gradually,while RI increased(P<0.01).Blood BMP-7 level was negatively correlated with IRA's and SRA's RI of IRA and SRA(r =-0.603,P<0.01;r =-0.652,P<0.01).Conclusions Color Doppler ultrasound examination of renal blood flow combined with detection of BMP-7 might play an important role in early diagnosis of type 2 diabetic nephropathy.
