1、XX大学毕业论文低剂量rhGCSF对56例非血缘供者外周造血干细胞动员姓名:2014年6月25日作者:李佩张国芸朱苹吴禧倩牛强谢毅【摘要】本研究观察低剂量人重组粒细胞集落刺激因子(rhGCSF)对非血缘健康供者的影响,探讨用于中华造血干细胞捐赠者资料库提供的非血缘健康供者外周造血干细胞动员方案。56例非血缘健康供者接受rhGCSF5昭/(kg・d)皮下注射,在动员第4、5两天或第5、6两天采集干细胞,观察动员效果及不良反应,检测动员前后血常规指标、CD3+、CD4+、CD8+和CD20+细胞比例;对采
2、集物进行单个核细胞(MNC)和CD34+细胞计数;对所有供者随访至2006年5月31日。结果显示:在rhGCSF动员过程中出现1级毒副作用(按WHO分级标准):腰背酸痛17.9%(10/56)、焦虑失眠8.9%(5/56)、疲乏4・5%(3/56)等,无需特殊处理,无需终止动员。第4、5两天采集和第5、6两天采集所得的MNC分别是(5.95±1.52)xlO8/kg和(7.19±2.12)xlO8/kg;CD34+细胞分别是(3.03±1.09)xl06/kg和(7.92±2.50)xl06/kgo血
3、红蛋白水平、血小板量、CD3、CD4、CD8、CD20百分比动员前后无变化。结论:5pg/(kgd)rhGCSF用于非血缘健康供者的动员是安全而有效的。【关键词】粒细胞集落刺激因子;外周血;造血干细胞动员;非血缘供者PeripheralBloodStemCellMobilizationwithLowDoserhGCSFin56UnrelatedHealthyDonorsAbstractThestudywasaimedtoobservetheeffectofrecombinanthumangranulo
