摘要 目的探讨炎症状态下成纤维细胞生长因子(FGF)23与终末期肾病(ESRD)血管钙化的关系。方法成年雄性SD大鼠随机分为对照组(Ctr)组、慢性肾功能不全(CRF)组和炎症伴慢性肾功能不全(CRF+I)组。Ctr组用生理盐水灌胃持续6 w,CRF组用腺嘌呤灌胃持续6 w构建大鼠CRF的动物模型,CRF+I组每天用腺嘌呤灌胃持续6 w并隔日皮下注射10%酪蛋白(Casein,1.2 g/kg)构建大鼠炎症伴CRF动物模型。检测各组血清肌酐、尿素氮、磷以及血管组织的钙含量、α-平滑肌肌动蛋白(α-SMA)蛋白表达量、FGF23 mRNA表达水平等指标。结果α-SMA蛋白表达量,Ctr组明显高于CRF组和CRF+I组(P<0.05),CRF组明显高于CRF+I组(P<0.05);组织钙含量,CRF组和CRF+I组明显高于Ctr组(P<0.05),而CRF+I组明显高于CRF组(P<0.05);FGF23 mRNA表达,CRF+I组的相对表达量明显高于CRF和Ctr组(P<0.05),Ctr组和CRF组FGF23 mRNA的相对表达量无差异(P>0.05)。结论炎症除了可以直接引起ESRD血管钙化外还可以通过升高FGF23加剧ESRD血管钙化。
