摘 要:目的 了解信号转导淋巴细胞激活分子(SLAM)CD150在乙型肝炎(乙肝)疫苗无应答者体外外周血单个核细胞(PBMC)中的表达.方法 对2007年9月至2009年12月曾行乙肝疫苗接种、HBV标志物检测均阴性的202例患者进行标准程序再免疫,再接种后第7~12个月检测抗-HBs效价.根据抗-HBs效价判定无应答者18例(男11例,女7例);选取应答者18例(男9例,女9例)作为对照.采集无应答者与应答者静脉血18 mL,淋巴细胞分离液密度梯度离心法分离PBMC,流式细胞仪测定细胞膜表面分子CD150.采用SAS统计软件包进行t检验以及Spearman 秩相关检验.结果 乙肝疫苗免疫后,在特异性刺激剂rHBsAg作用下,PBMC中CD150的表达无应答者为(39.20±10.66)%,高于应答者的(23.73±12.41)%,差异有统计学意义(t=2.1947,P<0.05);CD3+CD4+细胞中CD150的表达无应答者为(49.64±11.94)%.亦高于应答者的(37.73±11.02)%,差异无统计学意义(t=1.7175,P>0.05).在非特异性刺激剂植物血凝素(PHA)作用下,PBMC中CD150的表达在无应答者为(39.21±7.37)%,高于应答者的(23.18±12.68)%,差异有统计学意义(t=2.2835,P<0.05).在特异性刺激剂rHBsAg作用下,CD150在PBMC及CD3+CD4+细胞中与抗体效价呈负相关(r=-0.726,P<0.05).结论 CD150可能在机体接种乙肝疫苗后的无应答者中发挥一定作用. 关键词:肝炎疫苗,乙型;信号转导淋巴细胞激活分子(CD150);外周血单个核细胞

Abstract:Objective To study the expression of signaling lymphocytic activation molecule (SLAM)CD150 in peripheral blood mononuclear cells(PBMCs)isolated from adult non-responders to recombined yeast gene hepatitis B vaccine.Methods A total of 202 cases were recruited.All these subjects had been immunized with recombined yeast gene hepatitis B vaccine for more than one standard scheme in two years(from Sep 2007 to Dec 2009)and remained negative for hepatitis B markers(H[1] [2] [3] 下一页 上一个医学论文: 乙型肝炎病毒和丙型肝炎病毒不同模式重叠感染患者临床特征分析 下一个医学论文: 干扰素α与阿德福韦酯不同联合方法治疗HBeAg阳性慢性乙型肝炎的疗效
