Abstract： 目的探讨再生障碍性贫血(AA,再障)患者血清可溶性细胞间粘附分子-1(sICAM-1)和转化生长因子β1(TGF-β1)水平及其意义.方法采用ELISA法检测再障30例和骨髓增生异常综合征(MDS)15例,正常对照组20例血清sICAM-1和TGF-β1水平.结果慢性再障(CAA)组sICAM-1较正常组明显增高(p<0.05),TGF-β1较正常组明显降低(p<0.01);重型再障(SAA)和MDS组sICAM-1均较正常组显著增高(p均<0.01),TGF-β1均较正常组显著下降(p均<0.01).SAA组sICAM-1较CAA组显著增高(p<0.05),MDS组与CAA组比较,sICAM-1明显增高(p<0.01),MDS组与SAA组比较,TGF-β1明显增高(p<0.01).动态观察10例再障,随着病情的好转,sICAM-1水平逐渐下降,TGF-β1水平趋于上升;当病情加重时,sICAM-1上升,TGF-β1下降.血清sICAM-1和TGF-β1接近正常者疗效、预后好.结论高水平的sICAM-1和低水平的TGF-β1可能参与再障造血干/祖细胞衰竭的病理生理过程;动态检测sICAM-1和TGF-β1水平,为再障患者监测病情、评价疗效、指导临床治疗及预后判断提供较为客观的指标.
