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）。

With polyoxyethylene nonyl phenol ethers (OP-10) as emulsifier and dodecyl benzene sulfonic acid as catalyst, hydroxy organosilicon microemulsion was prepared through octamethylcyclotetrasiloxane (D4) open-ring polymerization under certain conditions.
