肺

Consequently, left lung has nine bronchopulmonary segments, right lung has twelve bronchopulmonary segments.

因此 ，左肺有 9个支气管肺段，右肺有 1 2个支气管肺段。

OBJECTIVE: To study the effects of prolonged 75% oxygen exposure on the expression of vascular endothelial growth factor and its receptors (VEGFR1 and VEGFR2) in the neonatal rat lungs and to elucidate the effects of prolonged exposure of high concentration of oxygen on lung vascular development and its relationship with bronchopulmonary dysplasia.

目的：研究持续吸入75%氧对新生大鼠肺血管内皮生长因子（vascular endothelial growth factor，VEGF）及其受体（VEGFR1和VEGFR2）表达的影响，探讨较高浓度吸氧对肺血管发育的影响及与支气管肺发育不良（bronchopulmonary dysplasia，BPD）的关系。

Objective Oxygen toxicity plays a major role in the pathogenesis of bronchopulmonary dysplasiain neonates requiring ventilation.

支气管肺发育不良(bronchopulmonary dysplasia， BPD)是一种因长期用氧，氧毒性使肺组织纤维化及肺萎陷的病变［1］。

Objective To probe the diagnostic value and limitations of thoracic CT and X-ray plain film on giant bulla, and the relationship of giant bulla with adjacent lung tissue, in order to provide the imaging basis for surgical selection.

李坤成 ，尹建国，董岩青目的探讨巨大肺大泡胸部X线平片和CT的诊断价值和限度，巨大肺大泡与邻近正常肺组织的关系，为选择手术适应证提供影像学依据。

78 cases, among them the lobectomy and pneumonnectomy 42 cases, pulmonary bulla rection and repair (include the video-assisted thoracic surgery, VATS), the lung volume reduction 10 cases, the oesophagus surgical operation 16 cases, the mediastinal operation 2 cases, the pyothorax operations 4 cases, and the other thoracic surgical 4 cases.

78例胸外科手术，其中肺叶、全肺切除手术42例，肺大疱切除修补（包括电视胸腔镜，VATS）、肺减容手术10例，食管手术16例，纵隔手术2例，脓胸皮质剥脱术4例，其他手术4例。

MAIN OUTCOME MEASURES: Heart function was evaluated by ultrasound cardiography 2, 4 weeks after transplantation; hemodynamics was measured before and 4 hours following CPR.

主要观察指标：移植后2，4周用超声心动图测量心功能；测量心肺复苏前及心肺复苏后4 h内的血液动力学参数的变化；在心肺复苏 72 h 后取心肌组织进行病理切片检查。

The level of serum amylase, the pulmonary dry/wet weight ratio and histological changes were measured at different time points in each group. The expression of pulmonary CINC protein and mRNA were detected by immunohistochemistry and semi-quantitative reverse transcriptase polymerase chain reaction, respectively.

分别检测各组不同时间点血清淀粉酶、肺干湿重比和肺组织病理学改变，用免疫组织化学法和半定量逆转录聚合酶链反应法检测肺组织中CINC蛋白和CINC mRNA表达的变化情况。

The slow progress of researches on pulmonary stem cells up to date has its root in the complex structure of pulmonary tissues and respiratory tracts, which is demonstrated by the facts that the respiratory system is composed of at least 40 types of cells, plus that the growth, renewal, and regeneration rate or capacity of respiratory epithelium are extremely limited. Mean while, there have been no specific stem cell markers for pulmonary and lung cancer, so researchers rely on stem cell markers borrowed from other systems to search for stem cells in pulmonary system.

目前对于肺干细胞的研究进展缓慢，究其原因主要是肺组织和气道具有复杂的内在结构，呼吸系统至少包含40种不同类型的细胞，呼吸上皮本身只有极低的生长更新率和非常有限的再生能力，同时肺干细胞的表面标志物也缺乏特异性，只能借助其他组织已知的干细胞标记物进行对比观察。

Objective: To investigate the changes of maleic dialdehyde levels and superoxide dismutase activities in the lung tissues of rabbits with endotoxin-induced acute lung injury, and study the protective mechanism of xuebijing.

目的：观察内毒素致兔急性肺损伤时肺组织中丙二醛含量及超氧化物岐化酶活性的的变化，探讨血必净对急性肺损伤保护作用的机制。

The changes of the pulmonary function parameters:lung resistance and dynamic lung compliance,were measured to evaluate asthma severity continuously.

实时测量哮喘豚鼠肺功能参数，肺动态顺应性和肺阻力的变化，作为反映哮喘严重程度的指标。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.
