Abstract
目的研究人血25-(OH)-VitD含量与CD4+T-淋巴细胞绝对计数的相关性,了解VitD对人体免疫系统的作用和影响。方法采用高档LC-MS/MS质谱仪,利用生物芯片技术测定CD4+T-淋巴细胞绝对计数,利用25-(OH)-VitD金标准方法测定284例病人血中25-(OH)-VitD总含量、25-(OH)-VitD2含量和25-(OH)-VitD3含量,并采用统计学方法,研究其与CD4+T-淋巴细胞的相关性。结果与CD4+T-淋巴细胞绝对计数的Pearson相关系数分别为:25-(OH)-VitD总含量0.172,P=0.004;25-(OH)-VitD2含量0.0034,P=0.660;25-(OH)-VitD3含量0.192,P=0.001。结论 25-(OH)-VitD总含量及25-(OH)-VitD3含量与CD4+T-淋巴细胞绝对计数密切相关,而25-(OH)-VitD2含量与CD4+T-淋巴细胞绝对计数无关;VitD对人体免疫系统具有一定作用和影响。
