Pulmonary pneumatocele is a cystic lesion within the lung that usually occurs in associated with the penumonia. It could enlarge to compress the adjacent lung, heart, mediastinum, then to cause respiratory or cardiovascular compromise, and possibly fatal outcome.

肺囊肿是肺内的一个囊状病兆，通常它的发生和肺炎有关，肺囊肿可以慢慢增大到压迫周围的肺、心脏和纵隔腔，造成呼吸或心脏衰竭，甚至可能会致命。

objective to evaluate the main points and complications of ct-guided percutaneous pneumocentesis in patients with lung lesions.methods cook 18～21g puncture needle was used to inserting aspiration in the optimal level,situs,angle and depth.and had made of multidrop.fifty-nine patients with lung lesions underwent ct-guided percutaneous pneumocentesis and follow-up.results the successful puncture rate was 100%,accurate diagnose rate was 92%(54/59).conclusion ct-guided pneumocentesis for chest lesion is a efficient and safe diagnostic method.but it is important to improve the doctor′s operating skill to lessen vascular complication.

目的 探讨ct引导下经皮肺穿刺活检的技术要点及并发症。方法采用cook公司18～21g自动弹射活检枪，选择最佳层面、进针点、进针角度和深度，行多点取材。回顾性分析59例肺内病变ct引导下经皮肺穿刺活检术。结果穿刺成功率100%，活检诊断准确率为92%（54/59）。3例发生轻度气胸，2例穿刺后咯血痰。结论 ct引导下经皮肺穿刺活检术成功率高，是安全的，但操作医生熟练的技术方法非常重要，并可以减少并发症的发生。

We found for the first time that the epithelium of bronchus of normal broilersexpressed iNOS mRNA.iNOS activity in the epithelium of bronchus of preascitic andascitic broilers were higher than normal broilers,but there was no iNOS activity inpulmonary vessels of all the three types broilers.The results indicated that the increasedNOS expression in pulmonary vessels of preascitic and ascitic broilers was not iNOS.

首次发现在肉鸡肺动脉高压发展过程中，肺血管NOS的表达是增加的，尤其是正常鸡无NOS表达的肺小血管内皮和平滑肌在腹水鸡却呈高水平表达，且NOS活性增加的肺小血管也同时存在管壁平滑肌层增厚或无肌型血管肌化的结构重建现象，结果提示NOS表达增强可能与肺血管中膜增厚有关。

Methods: This study investigated 284 coal miners, including 122 with X-ray Category 0 and 162 with Categories 1, 2, and 3, from the medical clinics of a hospital. Spirometric measurement and tests for pulmonary diffusing capacity were conducted on each subject.

Results Thirty-one(7.64%) of 406 patients showed abnormal ventilatory function, while 165 of 404 patients showed diffusing abnormality. Of the 434 patients who had received HRCT scans,151(34.79%) showed abnormalities including subpleural and basal ground-glass and reticular attenuation,nodular septal thickening and bronchiectasis. Of the 395 patients who had received both lung function test and HRCT scanning,55(13.92%) had abnormalities both in the lung function and HRCT.

结果 在4 0 6例进行肺通气功能检测的患者中，31例(7 6 4 %)异常；4 0 4例进行肺弥散功能检测，其中16 5例(40 84 %)异常；4 34例进行胸部HRCT检查，15 1例(34 79%)异常，表现为磨玻璃密度阴影、网格状阴影和胸膜下弧线影等；395例同时接受肺弥散功能检测和胸部HRCT检查，5 5例(13 92 %)两项均异常，且HRCT显示双肺病变典型者的肺弥散功能较HRCT正常者有显著的下降，两组差异有统计学意义。

A series PCR amplification for differential control strains and DNA samples diluted gradient (1:10) have been used to evaluate the specificity and sensitivity of PCR assay established.Results 1. Detection of GAS by PCR assay: The 345bp specific fragment of speB gene were amplified in all the tested GAS strains including three strains of scarlet fever, whereas it was detected in none of the differential control strains. The lowest limit of detection was 6.5pg genome DNA of GAS strain. 2. Detection of corynebacterium diphtheria by PCR assay: The318bp specific fragment of toxB gene were amplified in all the tested toxigenic corynebacterium diphtheria strains, whereas it was detected in none of the differential control strains. The lowest limit of detection is 850fg/μl genome DNA of corynebacterium diphtheria strain. 3. Detection of Lp by PCR assay: The 340bp specific fragments of mip gene were amplified in all the tested Lp strains, whereas it was detected in none of the differential control strains including three strains of non-pneumophila.

Whereas changes in extravascular lung water of less than 100-200% are undetectable by other clinically applicable methods of lung injury assessment (chest radiograph and oxygenation), the single transpulmonary indicator has proven highly sensitive to small (10-20%) increases and is therefore useful to detect incipient pulmonary edema.

尽管肺血管外水分在小于100-200%的变化能够通过其他评估肺损伤的方法来评价，但是单向跨肺热指示剂法被证实能够敏感到发现10-20%的肺血管外水分的变化，因此对于发现初始的肺水肿更为有用。
