Methods Review analysis 50 cases with mediastinal emphysema, and which were had the integrity chest X?

回顾性分析50例纵隔气肿的X线胸片（36例）和螺旋CT（41例）表现。

However, another investigation12 using the immunolocalization of MMP1, MMP2, MMP9, and MMP14 (MMP14 is a membrane-bound MMP) showed elevated levels of MMP2 and MMP14 in macrophages, as well as in the type II cells and fibroblasts, in emphysematous, compared to nonemphysematous, tissue.

但是在另一项对MMP 1，MMP 2和MMP 14（MMP 14 为有膜MMP）的免疫定位的研究中发现，气肿性组织较非气肿性组织而言，巨噬细胞中的MMP 2与MMP 14水平有升高，II型细胞和层纤维细胞亦如此现象。

Resujts:① The distribution of lesions are mostly symmetrical, extensive, predominant in the middle and lower lung fields, and posterior areas in peripheral;② There are so many HRCT findings of lung, ILD is predominant: intralobular interstitial thickening 46 cases (100%), ground-glass opacity 41 cases (89.13%), peribronchovascular or centrilobular interstitial thickening 40 cases (86.96%), interlobular septal thickening 38 cases (82.61%), irregular linear opacity 37 cases (80.43%), small nodular opacity 34 cases (73.91%), subpleural line 27 cases (58.70%), bmnchiectasis or bronchiolectasis 19 cases (41.30%), patch opacity 18 cases (39.13%), expiratory mosaic sign 15 cases (32.61%), interface sign 14 cases (30.43%), honeycombing 12 cases (26.09%), emphysema or bulla 3 cases, cystic airspace suspected 1 case, and atelectasis suspected 1 case;③ Mediastinum and pleura: multiple small lymphonodi in mediastinum 41 cases (89.13%), pleural thickening or rough 38 cases (82.61%), esophagoectasis 11 cases (23.91%), unilateral little pleural fluid 1 case, and mediastinal emphysema 1 case.

结果：①皮肌炎肺部病变分布呈对称、广泛、偏中下、偏外后的特点；②肺部HRCT表现多样，以肺间质性改变为主：小叶内间质增厚46例(100%)，磨玻璃影41例(89.13%)，支气管血管束增宽或小叶核心增大40例(86.96%)，小叶间隔增厚38例(82.61%)，不规则纤维索条影37例(80.43%)，结节影34例(73.91%)，胸膜下线27例(58.70%)，支气管或细支气管扩张19例(41.30%)，斑片影18例(39.13%)，呼气相马赛克征15例(32.61%)，界面征14例(30.43%)，蜂窝影12例(26.09%)，肺气肿或肺大泡3例，单纯囊状气腔1例，肺不张l例；③纵隔及胸膜：纵隔小淋巴结影41例(89.13%)，胸膜增厚或毛糙38例(82.61%)，食管扩张11例(23.91%)，单侧少量性胸腔积液1例，纵隔气肿1例。

When pneumomediastinum and loculated pleural effusion are encountered on chest radiography, the possible origins of the air should include thoracic organ invasion by gas-forming bacteria.

临床上，当胸部X光片发现纵膈腔气肿和多处肋膜积水时，我们要把会侵犯到胸腔器官的产气细菌当作可能造成气肿的来源。

We describe herein a female with proven sarcoidosis stage I whose HRCT scan showed air trapping during expiration and lung biopsy via video-assisted thoracoscopy revealed air trapping-related emphysema and non-necrotizing granulomas with peribronchiolar compression and intrabronchiolar involvement.

在此，我们描述一位第一期类肉瘤女性患者，其高解析度电脑断层摄影在吐气期呈现气滞型态。胸腔镜肺部切片证实非坏死性肉芽肿在小支气管周围有压迫以及小支气管内侵犯的情况，伴随周边肺泡的气肿。

Objective To analyze the clinical features of pneumomediastinum complicated in polymyositis and dermatomyositis and to study the pathogenesis thereof.

目的研究多发性肌炎／皮肌炎并发纵隔气肿的临床特点，探讨其发病危险因素及致病机制。

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。
