Comparisons between the cell lines were made on the basis of time to observed cytopathic effects, ultra structure changes, titer in 50% tissue culture infectious doses, and the alterant distribution of DNA content in cell cycle. The results showed that, under identical conditions, various degrees of CPE could be found in the Hep-3B, A549 and NIH 3T3 36h post infection of BTV-10, while there was no CPE could be observed in HEL.

随后在对BTV-10体外感染特性的研究中，我们在相同条件下，将该病毒接种于1株原代人胚肺成纤维细胞(Human embryonic lung fibroblast cells，HEL)和3株传代细胞株：人肝癌细胞(Human hepatic carcinoma 3B cells，Hep-3B)；人肺腺癌细胞(Human lung carcinoma A549 cells，A549)；鼠正常成纤维细胞(Normal mouse fibroblastscells，NIH 3T3)。

Results Pulmonary carcinosarcoma and blastoma both were found to be rare malignant tumors, and both epithelial and mesenchymal elements can be seen under the microscopy with different characteristic features.

结果 肺癌肉瘤及肺母细胞瘤均为肺内罕见的恶性肿瘤，镜下均可见上皮及间质两种成分，但又有其不同之处，手术前很难确诊。

This represents the pressure at which the lung begins to stiffen and over distend during inflation.

这显示的是肺在不扩张的状态下积聚在通道的压力；上拐点是肺活量与气道压力突然停止上升所产生的压力，这显示的是肺在扩展状态下变硬和扩张的压力。

The treatment group (n=30) received an intravenous infusion of ET-receptor antagonist PD142893(0.1mg/kg) 0.5ml, five minutes before unclamping the hemostat. The control group received NS. At 0h, 1h, 2h, 6h, 12h and 24h after transplantation, animals were anesthetized to obtain sample. The left pulmonary venous blood gas, plasma ET-1 and IL-6 were detected. The pathologic condition of transplanted lung was observed and apoptosis was detected by TUNNEL.

分别于移植后0、1、2、6、12、24小时，动物麻醉接呼吸机，原切口进入胸腔，采集标本，各时间点为5只大鼠，采集移植侧肺静脉血行血气分析，检测血浆ET-1和IL-6水平，移植侧肺的上1/3常规病理切片，中1/3用TUNEL法检测凋亡细胞并计数，下1/3检测肺湿/干重比。

The biology mechanism of balloonflower root targeting function to lung may be related to the content of VIP in lung which in the case of pathological conditions.

桔梗引经入肺的作用机制，有可能与其增加病理状态下肺组织中VIP含量有关。

Results Pulmonary carcinosarcoma and blastoma both were found to be rare malignant tumors, and both epithelial and mesenchymal elements can be seen under the microscopy with different characteristic features.

结果 肺癌肉瘤及肺母细胞妻子瘤均为肺内罕见的恶性肿瘤，镜下均可见上皮及间质两种成分，但又有其不同之处，医学手术前很难确诊。

Objective To research the relationship between the methodology and accuracy in percutaneous lung biopsy for decreasing the complication and ameliorating the successful percentage of pulmonary limitary lesion by ultrasound-guided.

目的探讨超声引导下对肺周围性病变穿刺活检及其命中率的关系，提高超声引导下肺周围性病变穿刺活检的成功率。

Results:There were multiple small nodules in bilateral lungs in 9 cases.Bullerfly wing-like shadow was showed beside bilateral lung hili in 3 cases.Great piece shadow can be found in both inferior lungs in 3 cases.

结果：15例中9例表现为双肺广泛分布的小结节状阴影，3例表现为以肺门为中心，向外放射的蝶翼状阴影，3例表现为双下肺野大片状致密阴影。

Objective To evaluate the diagnostic accuracy in terms of surface location, the needle, sampling method and the character of lesion. To investigate the complication of CT-guided percutaneous pulmonary biopsy with spring core biopsy needle.

目的 评价CT导引下应用弹簧芯状活检针经皮肺穿刺活检术中CT定位方法、穿刺针的选择、组织取材方法、病变特点等因素对本项检查诊断准确性的影响，探讨CT导引下应用弹簧芯状活检针肺穿刺活检术并发症的发生率、影响因素以及防治措施。

The diagnostic accuracy can be improved using the CT guiding spring core biopsy needle for percutaneous pulmonary biopsy for both malignant tumor and benign lesion. Especially for benign lesion the diagnostic accuracy with spring core biopsy needle was distinctive higher than that with fine needle aspiration.

CT导引下使用弹簧芯状活检针经皮肺穿刺活检的并发症发生率与细针针吸活检相近，对肺内良性病变和恶性肿瘤的诊断准确性同样具有较高的准确性，特别是对肺内良性病变的诊断准确率明显高于针吸活检。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
