单倍相合异基因外周血联合骨髓造血干细胞移植的干细胞采集及移植效果评价

目的采集单倍相合异基因供者外周血和骨髓中的造血干细胞,分析不同采集方式的差异,并进行移植后的效果评价。方法单倍相合异基因造血干细胞移植的受者为2006年6月-2008年12月在第三军医大学新桥医院血液科就诊的56例白血病患者,健康供者为患者的父母或兄弟姐妹。在供者皮下注射重组人粒细胞集落刺激因子进行造血干细胞动员,当外周血单个核细胞(MNC)>4.0×109/L时用血细胞分离机采集外周血中的造血干细胞,采集后1h内输给受者。56例供者根据骨髓造血干细胞的采集方法不同分为3组:第1组(n=5)采用注射器针头半密闭式过滤法,第2组(n=6)采用Thomas不锈钢开放式过滤法,第3组(n=45)采用本课题组的改进方法(用过滤输血器替换注射器针头及不锈钢网)。如若供、受者ABO血型不合,则对采集后的骨髓液进行处理:主侧不合用羟乙基淀粉沉降法去除红细胞,次侧不合采用低温低速离心去除血浆。骨髓液干细胞采集后4h内输给受者。结果56例供者外周血采集量的中位值为56ml,MNC中位值5.15×108/kg,CD34+细胞中位值5.80×106/kg;骨髓液采集量中位值950ml,有核细胞(NC)中位值10.31×108/kg...

Evaluation of efficacy of transplantation of haploidentical allogeneic stem cells collected from peripheral blood and hone marrow

Objective To evaluate the therapeutic effects of transplantation of haploidentical allogeneic stem cells, and the difference between those collected from peripheral blood and from bone marrow. Methods Fifty-six patients with leukemia, admitted to Department of Hematology of Xinqiao Hospital from Jun. 2006 to Dec. 2008, were enrolled as recipients who received transplantation of haploidentical allogeneic stem cells, with their family members including, parents, brothers or sisters as the donors. All donors w...
