研究急性非淋巴细胞白血病（ANLL）基因分型和微小残留病（MRD）的检测方法，选择IgH、TCRr基因重排标记．用PCR技术，对31例ANLL患者进行检测．结果：IgH阳性12．9％（4／31），TCRr阳性6．45％（2／31），表明ANLL中存在IrH和TCRr基因重排．对MRD的研究有一定的临床意义．
To study the detection methods of acute nonlymphocytic leukemia (ANLL) genotyping and minimal residual disease (MRD), and to select IgH and TCRr gene rearrangement markers. PCR was used to detect 31 patients with ANLL. RESULTS: IgH positive was 12.9% (4/31), TCRr positive was 6.45% (2/31), indicating that there was rearrangement of IrH and TCRr gene in ANLL. The study of MRD has a certain clinical significance.
