Abstract:
ObjectiveTo investigate the correlation of radial artery and serum osteoprotegerin (OPG) expression and vascular calcification in patients with end stage renal disease.MethodsDiscarded radial arteries were gathered from 43 patients with end stage renal disease(end stage renal disease group)during arterial venous fistula plasty,including 24 patients with no calcification,13 patients with mild to moderate calcification and 6 patients with severe calcification,20 patients with dialysis and 23 patients without dialysis.Discarded arteries from 9 patients with upper limb trauma were chosen as control group.The yon Kossa staining,alizarin red staining and OPG immunohistochemical staining were taken and serum OPG level was measured for all the patients.ResultsSerum OPG level was significantly higher in end stage renal disease group than that in control group [(216.47±83.78) ng/L vs.(57.15±23.22) ng/L,P＜ 0.01 ].Serum OPG level in patients with no calcification,mild to moderate calcification and severe calcification[ ( 152.21±32.21 ),(248.31±53.86),(368.44±53.57) ng/L] and OPG staining value ( 1,2,4 scores) were increased gradually as vascular calcification more serious (P＜ 0.01 ).There was a positive relationship between serum OPG and vascular calcification value(alizarin red staining:r =0.517,P ＜ 0.01 ; yon Kossa staining:r =0.677,P＜ 0.01 ).Serum OPG level and OPG staining value in patients with dialysis were higher than those in patients without dialysis [ (283.57±79.02 ) ng/L vs.( 152.46±30.89 ) ng/L,2 scores vs.1 score,P ＜ 0.01 ].ConclusionsThere is relationship between serum OPG level,OPG expression of radial artery and vascular calcification.
