Objective: To assess the diagnostic value between preoperative and post-op with volume-reduced bullae by quantitative CT pulmonary function.

目的：研究定量CT肺功能对肺大泡减容术前及术后的肺功能评估。

Results In 22 cases of giant bullae with a minimal cavity of 10cm×7cm×5cm to a maxmal cavity of 15cm×8cm×30cm,19 cases were cured with disappearred cavities in 7 days after the procedure, 1 case in 15 days, and 2 cases with reduced cavities in 10 days and 14 days respectively.

结果 22例肺大疱中最小者约10cm×7cm×5cm（前后径×内外径×上下径，下同），最大者约15cm×8cm×30cm。19例在术后7天内肺大疱闭合，1例在术后15天闭合，2例在术后10天和14天缩小并稳定，所有病例均获呼吸困难减轻或消失，肺功能改善。

Imaging from micro-CT of rats could reflect radiologic changes of pulmonary fibrosis in different stages.Sign of linear opacities is a mark which suggests the formation of moderate or severe pulmonary fibrosis and sign of bullae or pneumothorax is a cue of the formation of severe pulmonary fibrosis.

Micro-CT能显示大鼠PF不同阶段的影像学改变，线状影可作为鉴别Ⅱ～Ⅲ级肺纤维化形成的标志，肺大泡或气胸对Ⅲ级肺纤维化形成有提示作用。

Methods Lung volume reduction surgery by intra-bullous adhesion pexy with biomedical fibrin sealant and closed drainage by percutaneous lung centesis were carried out in 22 cases of giant bullae with a prospective random self-controlled study.

采取前瞻性自身对照的方法，对22例巨大肺大疱实施在CT定位下行经皮肺大疱穿刺注入医用生物胶内固定、置入导管引流持续负压吸引肺大疱减容的治疗方法。

Methods Before the total correction of TOF was performed, the collateral arteries were transcatheter closured in 3 cases with huge aorta pulmonary collateral arteries (2 cases with PDA occluder, 1 case with coil).

术前介入治疗：3例有巨大体肺侧支的重症TOF在根治术前予以侧支血管堵塞术，其中2例采用国产动脉导管未闭封堵器堵闭体肺侧支血管，1例采用可控弹簧圈栓塞体肺侧支血管。

The rabbit model of lung contusion was used to measure the changes in various physical parameters and inflammatory mediators such as C3a, C5a, IL-8 in bronchoalveolar lavage fluids of the contused lung.

利用家 兔肺挫伤模型，测定治疗前、后挫伤肺各项物理指标及挫伤肺局部支气管肺泡灌洗液中炎性介质 C3a、C5a、白细胸介素8(IL-8)的变化。

We observed the correlation between the dynamic change of the serumconcentration of NOS and hemodynamics index,found the serum concentration ofNOS was depressed observably after lung contused and NOS was actived and arrivedpeak at 24h after injected LPS.L-arigin can improve hemodynamics index andthe lung wet/dry index in lung contusion phase; Aminoguanidine can improvehemodyamics index and the lung wet/dry index obviously in ARDSphase.

通过观察ARDS动物模型血清一氧化氮合酶浓度的动态变化以及与血气指标和血液动力学监测指标的关系，发现肺挫伤早期NOS的浓度明显降低，ARDS发生后NOS的浓度明显升高，并在24h达到其峰值，肺挫伤早期给予NOS促进剂、ARDS发生过程中给予NOS阻滞剂可明显改善血气及血液动力学指标、肺湿/干比。

Results X-ray characteristics is main clue in diagnosing first,metaphase,advanced heart failure,effused,infected or the sight of lung is depressed in first,metaphase,advanced heart failure.

正常肺小动、静脉直径1～3 mm，当心力衰竭时肺小动、静脉怒张可分为早、中、晚三期，心脏各房、室增大，淤血、渗出、感染、肺透亮度降低。

Lung is the place that undertakes gas is exchanged, lung is located in thorax, submit conic form, right lung is lefter lung slightly big.

肺是进行气体交换的场所，肺位于胸腔，呈圆锥形，右肺较左肺略大。

Abstract］ Objective To appraise application value of indirect digital radiographyin silicosis diagnosing.Methods The chest of the confirmed diagnosis of 103 cases of silicosis and 25 objects of observation are radiographed by the CR common thousand voltage and the tradition high thousand voltage,appraise the radiograph quality and divide the period of silicosis.

摘要］ 目的评价间接数字X线摄影术在尘肺诊断中的应用价值方法将确诊的103例尘肺患者和25例观察对象，分别用CR普通千伏（60～70 kV）与传统高千伏（120～130 kV）拍摄其胸部X线片，对其胶片质量和尘肺分期进行评定。

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。
