血管通路方式的选择对健康供者外周血造血干细胞单采产量影响的研究

目的 探讨不同的血管通路方式对健康供者外周血造血干细胞(peripheral blood stem cell,PBSC)单采产量的影响.方法 对2000年1月-2007年12月进行PBSC单采的118例健康供者根据2条血管通路方式组合不同分为4组.观察各组PBSC采集的产量,包括单个核细胞数(MNC)及CD34+细胞数. 结果 每例PBSC的产量分别为:肘静脉-肘静脉组MNC(5.31±2.29)×108/kg,CD34+细胞数(4.78±2.06)×106/kg;肘静脉-前臂静脉组MNC(5.11±2.34)×108/kg,CD34+细胞数(4.34±1.99)×106/kg;前臂静脉-前臂静脉组MNC(5.61±1.73)×108/kg,CD34+细胞数(4.60±1.42)×106/kg;肘静脉-桡静脉组MNC(4.60±×1.70)×108/kg,CD34+细胞数(4.05±1.50)×106/kg.4组的PBSC产量差异无统计学意义(P>0.05).结论 不同的血管通路方式不影响PBSC单采的产量.

The influence of the PBSC collection yield by choosing the different venous accesses in the healthy donors

Objective To investigate the influence of the PBSC collection yield by choosing the differ-era venous accesses in the healthy donors. Methods 118 healthy PBSC donors performing PBSC collection between January 2000 and December 2007 in our hospital were divided into four groups according to the differ-ent venous accesses. The PBSC collection yield of four groups,including mononuclear cells (MNC) count and CD34+ cells count were observed. Results In the ulnar V-ulnar V group,MNC (5.31±2.29)×108/kg,CD34+ cells (4.78±2.06)×106/kg;ulnar V- antecubital V group,MNC(5.11±2.34)×108/kg,CD34+cells(4.34±1.99)×106/kg;antecubital V- antecubital V group,MNC (5.61±1.73)±×108/kg,CD34+cells (4.60±1.42)×106/kg;ulnar V- radial V group,MNC(4.60±×1.70)×108/kg,CD34+cells (4.05±1.50)×106/kg.There was no statistical differ-ence of the PBSC collection yield between four groups (P>0.05). Conclusions Different venous accesses don't affect the PBSC collection yield in the PBSC healthy donors.
