摘要: 目的 探讨骨相关蛋白中骨桥蛋白(OPN)和非活性基质Gla蛋白(ucMGP)在维持性血液透析(MHD)患者合并动脉粥样硬化和心脏瓣膜钙化中的关系。方法 55例MHD患者和22例正常对照者作为研究对象。采用ELISA法测定2组受试者血中OPN和ucMGP含量。测定颈动脉分叉处内-中膜厚度(IMT),用超声心动图检测心脏瓣膜是否出现钙化,分析骨相关蛋白水平与动脉粥样硬化和心脏瓣膜钙化之间的关系。结果 MHD患者血中OPN及ucMGP显著升高。MGP在伴有颈动脉斑块和心脏瓣膜钙化组显著增高,其中OPN含量与颈动脉内膜厚度呈正相关关系(r=0.55,P<0.05)。结论 MHD患者血中OPN及ucMGP的增高伴随动脉粥样硬化和心脏瓣膜钙化的发生,可作为心血管钙化程度的检测指标。

Abstract: Objective To elucidate the association of osteopontin(OPN) and the circulating inactive form of matrix Gla protein(ucMGP) with the presence of cardiovascular calcification in maintenance hemodialysis(MHD)patients. Methods Serum OPN and ucMGP in 55 MHD patients and 22 health subjects at matching age were measured using ELISA. The intimal and medial thicknesses(IMT) in carotid artery were measured by doppler ultrasonography and the cardiac valve calcification by colour doppler ultrasonography. Results The levels of OPN and ucMGP in MHD patients were significantly higher than those in healthy ones. The concentrations of OPN were positively correlated with the IMT(r=0.55, P<0.05). The levels of OPN and ucMGP were higher in cardiac calcification group. Conclusion The levels of OPN and ucMGP may be associated with the presence of atherosclerosis and valvular calcification in MHD patients,and which may be used as markers for cardiovascular calcification.
