Results The displayed number of the segmental and sub-segmental bronchia with 2.5 mm thick slices was more than that of 5 mm and 3.75 mm. There were no differences between 5 mm and 3.75 mm, or 2.5 mm and 1.25 mm slices in the display of them.

结果 2.5mm层厚MDCT显示的肺段及肺亚段支气管数均高于5及3.75mmMDCT；5和3.75mm、2.5和1.25mm层厚MDCT对肺段及肺亚段支气管的显示数无统计学差异。

Results Both chest radiography and CT could depicted the size, location and morphology of the giant bulla, but CT could shown the wall and internal condition of bulla, adjacent emphysema, and compression of the normal pulmonary tissue.

结果 胸部X线平片和CT均能清晰显示巨大肺大泡的大小、位置和形态，但是CT还可显示巨大肺大泡的内部情况、肺大泡壁及邻近肺气肿和正常肺组织的受压情况。

The carboxyhemoglobin levels of in-flowing pulmonary blood and out-going pulmonary blood were determined at 2,4 and 6 hours after treatments. Malondialdehyde contents and superoxide dismutase activities in the lung,liver and blood were also determined. Pathological changes in lung and liver were examined with light microscope,and immunohistochemical technique was used for analysis of heme oxygenase-1 (HO-1) protein expression and distribution in lung and liver.

各组分别在制模后2、4和6 h测定出入肺血中碳氧血红蛋白水平；肺、肝组织及血液中丙二醛含量及超氧化物歧化酶活性；光镜下观察肺、肝组织形态学改变；免疫组化分析血红素加氧酶-1(HO-1)在肺、肝组织中的蛋白表达和分布。

The diseased lung tissues were serially ligated with the Roeders knot and the hilum of the lung tightly locked with a Rumel's hemostat. The raw surface of the resected lung was sutured.

术中采用Roeder结套扎肺组织或创用Rumel止血器锁紧肺根部、腔镜下缝合肺残端创面等方法处理病肺。

CT findings and pathoamatomic changes of traumatic wet lung、contusion of lung and laceration of lung were diverse and analyzed the mechanism of the delayed hemothorax and atelectasis.CT is the most effective examination for chest injuries and for guiding the clinical management.

创伤性湿肺、肺挫伤及肺撕裂伤的病理基础、CT表现各异，并探讨了迟发性血胸与迟发性肺不张的发病机制，CT是胸部损伤最有价值的检查手段，对临床具有指导意义。

In the thesis, Artificial Neural Network has been used to study the sample data of Pneumoconiosis, the quantitative model to show the relation between the incidence of Pneumoconiosis and three factors is built and tested by the practical data.

针对常规方法的不足，把神经网络技术用于尘肺发病规律的研究，建立了尘肺发病率与三因素间的实用化定量关系模型，并对三因素在尘肺发病中的贡献进行了研究，推导出相应的重要度公式；开发了"粉尘危害程度预测及动态仿真系统"软件，用于对尘肺发病规律的研究和预测。

In meloxicam-treatment group, PaO2/FiO2 remained in normal range, and the lung wet/dry, the lung wilier content and the expressions, of MMP-2 mRNA were significantly lower than those in ET group.

结果 与A组比较，B组氧合指数明显降低，肺组织出现水肿，出血、炎性细胞浸润，W/D比值、肺水含量及肺组织MMP-2 mRNA表达明显增加；C组氧合指数未见明显下降，W/D比值，肺水含量、肺组织中MMP-2 mRNA表达较B组减少。

Light microscope findings shown that the impairment in TyrphostinA1 groups was far less severe than that in model groups. In conclusion, Curcumine and TyrphostinA1 showed preferable effect on acute lung injury induced by oleic acid in rats.

结果表明，TyrphostinA1明显改善大鼠肺功能，减轻肺组织病理学损伤，降低肺指数及肺湿/干重比，降低肺渗透性和肺泡灌洗液中蛋白及TNF-α、IL-6的含量，提高肺泡灌洗液中IL-10的含量。

Compared with the control, the lungs of 3-day-hyperxia-exposure group developed into edema, hemorrhage and inflammatory infiltration and this condition aggravated at the 7th day. The pulmonary septum was significantly widened at the 14th day, the interstitial fibrocytes as well as alveolar epithelial cells proliferated obviously, and the tendency of lung fibrosis was also presented. The results mentioned above showed that the modle of hyperoxia lung injury was successfully established, and the acute inflamationm was its early symptom while the fibrosis was its late manifistation. There was no positive cytes of IFN-γ in the lung of nomal rats, The positive cytes of the groups under hyperxia-exposure for 3, 7, 14 day, which climbed to the climax at the 7th day and began to decline from the 14th day, were found in alveolus epithlia,pulmonary interstitial, bronchoepithlia and macrophage.

高氧14天（5.46±0.30）虽有所下降，但同空气组比，差异仍然具有显著性（P.05）；BALF中蛋白含量高氧3天（0.45±0.10）、7天（0.66±0.08）、14天（0.79±0.14）显著高于空气组（0.18±0.08，P值均。05）；肺通透系数高氧3天（6.61±2.05）、7天（10.88±1.54）、14天（12.75±2.20）均明显高于空气组（2.99±1.27，P值均。05）；同时病理组织学改变也表明与空气组比较，高氧3天时肺组织水肿、出血、炎性细胞浸润，7天时进一步加重，14天时肺间隔明显增宽，间质纤维细胞和肺泡上皮细胞明显增生，出现肺纤维化倾向；以上结果均表明我们成功地建立了高氧肺损伤动物模型，且急性炎症反应是其早期表现，纤维化改变是其晚期表现。
