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。

Then thrombectomy was performed with the ATD, HL, OASIS in inferior vana cava. All catheters were used according to the manufactuer's recommendations. Phlebography, pulmonary arteriography were performed, the pulmonary artery pressure and the weight of the clot, the remaining clot in the filter and lungs were measured before and after the procedure.

At the 28th day, tenuity of distal end of pulmonary artery, decrease of the branches, and thickness of proximal end of pulmonary artery were observed.

实验7、14天组肺动脉远端纹理明显增粗，分支增多，血管周围显示模糊，28天组肺动脉远端纹理纤细，分支减少，近端肺动脉增粗。

In this group,16 cases were involved in central pulmonary arteries (66.7%) and 4 cases with dilated bronchial arteries (17%),9 cases with pulmonary infraction (37.5%) whose pulmonary embolismic index was ranged from 24% to 83%, other 15 cases with no pulmonary infraction whose embolismic index was ranged from 5% to 61%,and there were significant difference between the two groups.

中央肺动脉受累16例，占66.7％（16/24），支气管动脉扩张4例，占16.7％（4/24），发生肺梗死9例，占37.5％（9/24）。9例发生肺梗死的肺动脉栓塞指数24％～83％（平均46.5％），15例非肺梗死的肺动脉栓塞指数5％～61％（平均21％），两组栓塞指数具有显著差异性。

Methods Collect and analyze the appearance in multi-slice spiral CT of 24 patients with pulmonary embolism,especially the embolismic index,the involved proportion of central pulmonary arteries,the presenting proportion of bronchodilation and pulmonary infarction.

搜集经多层螺旋CT动态增强扫描确诊的肺动脉栓塞24例，回顾性分析其CT表现，重点分析肺动脉栓塞指数、中央肺动脉受累比例、有无支气管扩张显示、是否合并肺梗死。

Abstract］ Objective To evaluate the value of spiral CT dynamic contrast-enhancement scanning on pulmonary embolism by analysing the CT appearance of pulmonary embolism restrospectively.Methods Collect and analyze the appearance in multi-slice spiral CT of 24 patients with pulmonary embolism,especially the embolismic index,the involved proportion of central pulmonary arteries,the presenting proportion of bronchodilation and pulmonary infarction.

目的 回顾性分析肺动脉栓塞的CT表现，探讨层螺旋CT动态增强扫描对肺动脉栓塞的诊断价值方法搜集经多层螺旋CT动态增强扫描确诊的肺动脉栓塞24例，回顾性分析其CT表现，重点分析肺动脉栓塞指、中央肺动脉受累比例、有无支气管扩张显示、是否合并肺梗死。

Twenty-six patients had subpulmonary VSD(diameter 0.8±0.8cm), 18 VSD lay immediately below pulmonary valve, 8 had muscle distant from pulmonary valve, 20 lay completely below pulmonary valve, and 6 lay below pulmonary valve and aortic valve.

3肺动脉瓣下型室间隔缺损26例（直径0.8±0.8cm），其中近邻肺动脉瓣18例，与肺动脉瓣有肌性相隔8例；单纯位于肺动脉瓣下20例，主动脉瓣和肺动脉瓣下6例。

Few of the endothelial cells and smooths muscle cells of the normal pulmonary artery were positive for t-PA.

栓塞后3小时，栓塞肺动脉和未栓塞肺动脉、正常肺动脉比较没有显著差异，较少见栓塞肺动脉内皮细胞和平滑肌细胞胞浆棕染的t-PA阳性细胞。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
