细支气管周的

As the CS exposure was extended to 4, 12, 18 and 24 weeks,the bronchiolar KC and MIP-2 expression and their levels in BAL fluid were relatively dampened compared to those at 10 days.

分别暴露CS4，12，18和24周，细支气管中的KC和MIP-2表达以及在BALF中的表达变化尚不明显。

PS is mostly synthesized and secreted by alveolar typeⅡ cells and also by Clara cells in the peripheral airways to a lesser extent, and approximately 7% of alveolar surfactant reaches the bronchiolar tree via the mucociliary escalar.

PS主要由肺泡Ⅱ型上皮细胞产生，少部分由外周气道的Clara细胞产生，约7％的肺泡表面活性物质经纤毛运送到达细支气管。

Eighteen (72%) chronic cases showed a pattern resembling usual interstitial pneumonia, but, in most cases, with more peribronchiolar fibrosis than one would expect in UIP.

慢性患者中有18例（72%）的组织结构类似寻常型间质性肺炎，但与UIP不同的是，绝大多数病例细支气管周纤维化病灶不只一处。

PaO2/FiO2 of both patients was less than 225 mm Hg.In both patients, high-resolution computed tomography scans at the exacerbation showed typical signs of IPF including peripheral predominant, basal predominant reticular abnormality, with honeycombing and traction bronchiectasis and bronchiolectasis,and newly developing alveolar opacity.

呼吸困难分别在1周和半月内加重；2例患者氧合指数均小于225 mm Hg；急性加重时2例患者HRCT表现为两下肺分布的网状影、蜂窝影、牵拉性细支气管扩张和支气管扩张等典型的IPF表现，并出现新的磨玻璃影。

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。
