Abstract
目的 研究复发/难治急性髓系白血病(AML)患者P-糖蛋白(P-gp)表达及其功能.方法 用免疫组化方法检测CD34表达,RT-PCR方法检测P-gp的表达,用流式细胞术检测P-gp的功能.结果 CD34表达与P-gp表达、功能呈正相关(r=0.621,P<0.001;r=0.496,P<0.001),P-gp表达与功能呈正相关(r=0.574,P<0.01);复发/难治组CD34阳性率(66.7%)高于初治组(32.6%)(P<0.05);复发/难治组P-gp功能阳性率(66.7%)高于初治组(25.6%)(P<0.01).结论 CD34表达、P-gp表达和P-gp功能三者间呈正相关;复发/难治AL组CD34阳性率、P-gp功能阳性率高于初治组;P-gp功能的检测更具有临床指导意义。
