Objective To detect the expression of CD70 in peripheral T lymphocytes of patients with systemic lupus erythematosus and the effect of azacitidine, an inhibitor of DNA methylation, on it. Methods Blood samples were obtained from 10 patients with active SLE （SLEDAI score ≥5）, 10 patients with nonactive SLE （SLEDAI score 5） and 10 normal human controls.

目的 通过研究共刺激分子CD70在SLE患者外周血T淋巴细胞的表达水平，以及DNA甲基化抑制剂氮杂胞苷对正常人外周血T淋巴细胞表达CD70分子的影响，探讨DNA甲基化在SLE患者外周血T淋巴细胞表达CD70分子中的调控作用。

Results The frequency of CD70+CD4+ lymphocytes was 14.55%± 5.49% in normal control group, 85.25%± 14.08% in active SLE group, 77.65%± 18.77% in nonactive SLE group, and 81.54%± 8.71% in methylation-inhibited group. Compared with the normal control group, a significant increase was observed in both the frequency of CD70+CD4+ lymphocytes （all P 0.01） and the expression of CD70 expression （all P 0.05） in other three groups.

结果 正常人外周血CD4+CD70+ T淋巴细胞阳性率为14.55%± 5.49%，活动期、非活动期SLE分别为85.25%± 14.08%和77.65%± 18.77%，甲基化抑制组为81.54%± 8.71%，与正常人对照组相比，活动期、非活动期SLE患者和甲基化抑制组CD70+CD4+ T淋巴细胞阳性率均明显升高（P 0.01），其外周血T淋巴细胞CD70 mRNA表达水平亦明显增加（P 0.05）；SLE患者外周血CD70+CD4+ T淋巴细胞阳性率与SLE疾病活动度呈显著正相关（r = 0.72，P 0.05）。
