Fisher's exact test and odds ratio with its 95% confidence interval were used to analyze the relationship of pulmonary artery to lesion with the possibility of malignancy. The degree of pulmonary arterial encasement in the benign lesion and malignancy was evaluated by Wilcoxon rank sum test. The agreement between 2 observers was evaluated by kappa statistics. In addition, the sensitivity and specificity profiles of the degree of encasement in diagnosis of malignancy were determined by plotting an empirical ROC curve.

肺部病灶及其邻近肺动脉之关系来预估恶性的可能的资料分析方法为费氏分析检定法(Fisher's exact test)，胜算比以及95%信赖区间；评估肺动脉被包埋压迫的程度用在预估恶性肿瘤之能力是使用威尔科克逊秩和检定；2位观察者间的同意度之检定是用Kappa 统计分析；除此之外，用肺动脉被包埋压迫的程度来预估恶性肿瘤之能力的敏感度以及特异性是用接受者操作特徵的曲线来评估。

A PCR product was amplified using RT-PCR method from total RNA from the abdomens of R strain using the degerated primer. The PCR product was purificated and cloned. The plasmid is pBluescript Ⅱ KS. Recombined plasmid DNA was identified by endoenzyme. The results indicated there were different P450 genes in the PCR product.
