Results AQP1 is expressed at the apical and basolateral membrane of the microvascular endothelium; AQP3 was detected at basal cells of both the bronchiole epithelium and submucosal gland acinus; AQP4 is present in the basolateral membrane of columnar cells in bronchiole; while AQP5 is expressed in the apical membrane of type Ⅰ pneumocytes, and also at the apical of columnar cells of superficial epithelium and submucosal gland acinar cells.

结果本研究发现AQPs基因在羊肺中的表达分布与人相似，AQP1在肺内的毛细血管内皮细胞表达；AQP3在小支气管黏膜上皮的基底细胞的基侧膜表达，AQP4存在于小支气管黏膜上皮的柱状纤毛细胞的基侧膜；AQP5存在于Ⅰ型肺泡上皮细胞的顶质膜，存在于小支气管黏膜上皮柱状纤毛细胞，以及在气道黏膜下腺的腺细胞的顶质膜表达。

Results: The most common locations of PIP were at the margin of both lower lobes and associated with local pleural thickening and adhesion. The density of nodule in which CT attenuation value was 15~60 HU (26.9±13.5HU) was lower than that of PLC. Most of them were round/round-like and irregular in shape. The interior density of lesion was inhomogeneous. The presence of calcification or multiple cavitations, straight margin sign, hole sign and without hilar and mediastinal adenopathy were of great significance in the diagnosis of such kind of disease.

结果：炎性假瘤多位于两肺下叶，邻近胸膜增厚、粘连，病灶密度偏低（平扫CT值15~60HU，平均26.9±13.5HU），与周围型肺癌比较有统计学差异，其形态以圆形／类圆形和不规则形多见，病灶内密度多不均匀，可见钙化及多发空洞，边缘呈平直状、周围见毛玻璃样改变及肺门纵隔无淋巴结肿大等征象对本病的CT诊断有意义。

Pulmonary function tests, oxygenation index,and atelectasis on chest radiograph were evaluated and comparedamong the groups.

各组间比较肺功能测试，氧指数，和胸片下的肺膨胀不全的情况。

The expression of CTGF and TNF-αweredetected by immunochemistry and the number of Clara Cells was calculated.

光镜下观察肺组织的病理变化，采用免疫组化染色观察肺组织中结缔组织生长因子和肿瘤坏死因子-α的表达和Clara细胞的数量。

Application of the QA method to MPA is more challenging than to aorta due to irregular shape of the cross sectional area.

然而，由於肺主动脉的形状变异比主动脉要大的许多，所以相较之下要运用同样的理论在肺主动脉上会增加许多困难。

Results The segmental bronchial ramifications of the left upper lobe were classified into three types mainly: common stem of apical and posterior segmental bronchi (64%, 130/200), trifurcation (23%,45/200), common stem of apical and anterior segmental bronchi (10%, 21/200), and they could be identified in two typical slices of transverse thin-section CT.

左肺上叶3种主要分支类型可以通过薄层CT横断面图像2个典型层面辨认；左肺下叶依据基底干支气管分支的不同分为2种主要类型，Ⅰ型163例(75%)：基底干支气管两分支，即内前底段支气管、外后底段支气管；Ⅱ型39例(18%)：基底干支气管3分支，即内前底段、外侧底段、后底段支气管。

这是肺间质纤维化的三色染色的镜下图片，可见肺组织的纤维化区被染成蓝色。

Objective To observe the modulation by Blood-cooling and Blood Flow-promoting Herbs to expressions of tumor necrosis factor u and basic fibroblast growth factors in radiation-induced lung injury of rats at different radiation times, and explore the mechanism of prevention and curative effect of the herbs on radsation lurg injury.

目的 通过观察凉血活血中药对剂量分割重复照射下大鼠肺组织肿瘤坏死因子-α、碱性成纤维生长因子在不同时相动态表达的影响，探讨其防治放射性肺损伤的作用机制。

Imaging appearances of AIDS complicated with pulmoanry tuberculosis coexisted with multiple foci of infection and polymorphism that distributed in multiple lobus. Most of AIDS patients were without typical tuberculous proliferative foci and lyphadenectasis, possibly to be associated with decreasing extent of immune function and the progress of disease at various stages in the young patients observed.

AIDS合并肺结核的胸部影像学特征多表现为多性质的病灶共存，多形态、多叶段分布，以两下肺明显的渗出性、多形态病灶；纤维化、钙化、肿块样阴影少见，无典型的结核增殖灶、肺门淋巴结肿、胸水产生与有关文献报道有异，可能与本组患者为年青人及免疫下降程度和病程发展不同阶段等因素有关。

A closer view of the lobar pneumonia demonstrates the distinct difference between the upper lobe and the consolidated lower lobe.

大叶性肺炎近距离观显示了肺上叶和发生实变的肺下叶之间的差别。

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。
