MethodsThe p73 gene ex- pression in 100 cases of AL including newly diagnosed and recrudescent or refractory ones and 20 normal controls was detected by relative quantitative reverse transcriptase polymerase chain reaction,and then the results were analyzed and compared by χ2-test,t-test and single agent variance. ResultsThe higher expression of p73 gene was found in 58% of AL cases.

采用RT-PCR方法检测100例初诊及复发或难治AL患者和20例正常对照者p73基因的表达，并采用χ2检验、t检验及单因素方差分析对结果进行统计学分析，以比较各组p73基因表达阳性率及表达强度差异。
