【摘 要】 目的 比较正常人与系统性红班狼疮(SLE)患者的造血干/祖细胞生长情况及从造血干/祖细胞水平探讨SLE的发病机制。方法 用半固体甲基纤维素集落培养法观察16例活动期及其中3例经治疗缓解的SLE患者的粒-巨噬细胞集落(GM-CFU)、红系集落(E-CFU)、巨核细胞集落(MK-CFU)。结果 活动期SLE患者的GM-CFU、E-CFU、MK-CFU分别为(182±50)、(56±27)、(8±5),均明显低于正常对照组,缓解期SLE患者的GM-CFU、E-CFU比活动期的明显增加,而MK-CFU与活动期比较无明显变化。结论 活动期SLE患者的造血干/祖细胞增生、分化功能异常,缓解后的SLE患者其巨核细胞系恢复迟于粒系、红系,SLE的发病可能与造血干/祖细胞的异常有关。 【关键词】 红斑狼疮,系统性; 造血干细胞; 集落形成单位测定

【Abstract】 Objective To compare SLE patients′ with controls′ hematopoietic stem/progenitor cell growth of bone marrow in vitro and research on the pathogenesis of hematopoietic stem/progenitor cell.Method GM-CFU,E-CFU and MK-CFU of 16 active SLE patients and 3 remission patients were cultured in vitro with semisolid methylcellulose.Results GM-CFU,E-CFU and MK-CFU in active SLE were (182±50),(56±27) and (8±5),respectively,and their yield was lower than that in controls.The yield of GM-CFU and E-CFU in remission patients was higher than in active patients,but MK-CFU had no obvious change in two groups. Conclusion Hematopoietic stem/progenitor cells of active SLE are abnormal in the functions of proliferation and differentiation.Recovery of MK-CFU is later than that of GM-CFU and E-CFU.The abnormality of hematopoietic stem/progenitor cells may be relative to pathogenesis of SLE. 【Key words】 Lupus erythematosus,systemic;Hematopoietic stem cell;Colony forming unit assay
系统性红斑狼疮(SLE)的病因尚未完全明了,越来越多的动物实验和临床研究证实,包括SLE在内的自身免疫性疾病存在造血干细胞的异常[1]。本研究旨在体外观察SLE患者骨髓造血干/祖细胞的生长情况,通过其结果进一步探讨SLE的发病机制。
