摘    要:目的:研究As患者PBMC维生素D受体(VDR)mRNA的表达及血清25-羟维生素D,和1,25-二羟维生素D3的水平,探讨其与AS疾病活动性(BASDAI、CRP、ESR)的相关性。方法:选取26例AS患者(As组)和年龄、性别与之相匹配的13名健康志愿者(健康对照组)。采用SYBRGreenI实时荧光定量PCR检测两组受检者PBMC的VDRmRNA表达水平,应用ELISA法检测两组受检者血清25-羟维生素D3和1,25-二羟维生素D3水平,分析VDRmRNA表达水平、血清25-羟维生素D3和1,25-二羟维生素D3水平与临床相关指标(BASDAI、CRP、ESR)的关系。结果:As患者PBMC的VDRmRNA表达水平明显高于健康对照组(P〈0.01),VDRmRNA表达水平与临床相关指标(BASDAI、CRP、ESR)无关(P〉0.05)。AS患者血清25.羟维生素D3、1,25-二羟维生素D3水平分别为(5.3±2.6)μg/L、(12.8±6.0)ng/L,明显低于健康对照组(14.7±3.5)μg/L、(32.6±18.5)ng/L(P均〈0.01)。AS患者血清1,25-二羟维生素D3的水平与BASDAI(r=-0.481,P〈0.05)、ESR(r=-0.535,P〈0.01)、CRP(r=-0.674,P〈0.01)均呈负相关。血清25-羟维生素D,水平与BASDAI、CRP、ESR无关(P〉0.05)。结论:As患者VDRmRNA表达水平升高,但与As的疾病活动无关。As患者血清1,25-二羟维生素D3水平下降,与疾病活动呈负相关,可作为AS疾病活动的指标之一。AS患者PBMC的VDR活化可能与1,25-二羟维生素D,的作用无关。

关 键 词:强直性脊柱炎  25-羟维生素D,  1,25-二羟维生素D3  维生素D受体

Abstract:Objective:To study the expression of vitamin D receptor(VDR) mRNA in peripheral blood monocytes of patients with Ankylosing Spondylitis(AS) and explore the correlation between the disease activity erythrocyte sedimentation rate(ESR),C-reactive protein(CRP),Bath Ankylosing Spondylitis Disease Activity Index(BASDAI)] and the serum levels of 25-hydroxyvitamin D3 25-D/ 25-(OH)D3] and 1,25-Dihydroxy vitamin D3 1,25-D/1,25-(OH)2D3)] in AS patients.Methods:Twenty-six patients with AS and 13 age-and sex-matched ...
Keywords:Vitamin D  25-(OH)D3  1  25-(OH)2D3  Vitamin D receptor  Ankylosing spondylitis
