摘要 目的通过检测类风湿关节炎(rheumatoid arthritis,RA)患者在应用注射用重组人Ⅱ型肿瘤坏死因子受体-抗体融合蛋白(recombinant human tumor necrosis factor receptor-Fc fusion protein,rhTNFR:Fc)治疗前后外周血T淋巴细胞Fas/Fas L水平的变化情况,了解rhTNFR:Fc对RA患者外周血T淋巴细胞凋亡的影响。方法 RA患者64例为治疗组,并随机分为3个亚组,甲氨蝶呤(methotrexate,MTX)组17例,rhTNFR:Fc组25例,MTX+rhTNFR:Fc治疗组22例;并选择正常体检者18例作为对照组。各组分别抽取rhTNFR:Fc治疗前后静脉血检测Fas/Fas L的水平,记录所有RA患者28个关节的关节压痛数、关节肿胀数,检测红细胞沉降率(erythrocyte sedimentation rate,ESR,魏氏法)、类风湿因子(rheumatoid factor,RF-IgM,比浊法),并计算28个关节疾病活动指数(disease activity score 28,DAS28)。结果各组RA患者治疗前外周血中关节压痛数、关节肿胀数、ESR、RF、DAS28、Fas、Fas L、Fas/Fas L水平均比正常对照组明显增高,治疗后各指标均明显下降,其中MTX+rhTNFR:Fc组较其余2组更为显著(P<0.01)。RA患者在接受rhTNFR:Fc治疗后,Fas/Fas L与ESR、RF、DAS28呈正相关(r=0.441、0.527、0.466,P<0.01)。结论 rhTNFR:Fc可以通过抑制活化的T淋巴细胞分泌肿瘤坏死因子α,下调RA外周血淋巴细胞Fas系统的表达,最终达到抗风湿的作用。
