摘要 目的探讨流式细胞仪在急性粒细胞白血病(acute myeloid leukemia,AML)免疫分型中的特点和规律。方法利用流式细胞术中CD45/SSC双参数散点图设门法,对四色荧光素(FITC、PE、PC5、ECD)标记的骨髓血细胞免疫表型分析。取初发患者骨髓单细胞悬液100μl加入到测试管中,再加入特定抗体,室温避光1 h,然后经溶血处理,上机检测。每管均设置同型对照。结果在76例AML中,髓系相关抗原MPO、CD33、CD65表达最高,总阳性率分别为96.1%、94.7%和93.4%,CD13、CD15、CD16的表达率较低,总阳性率分别为50.0%、63.2%和89.5%;CD14、CD64在M4、M4EO、M5中阳性率最高;CD41、CD61在M7中的阳性率最高;CD34在M1和部分M2中强表达,但总阳性率约为46.1%。结论本研究成功分析不同亚型AML的CD45/SSC散点图异常细胞分布的特定位置,同时结合各种不同系列分化特异性抗原的表达综合分析,实现与FAB法在AML分型比较符合率高达97%。
