肺动脉

The Chronic Cardiopulmonary Disease, pulmonary hypertension is frequently encountered illness in clinic, and PAH is one of the COPD patients' most common and severe consequences in hemadynamics. It is also one of the diagnostic codes of CCD, the severity direct influence the disease's prognosis.

慢性肺心病肺动脉高压是临床多发病，而肺动脉高压是中老年慢性阻塞性肺病在血液动力学方面最多见和最严重的后果之一，也是慢性肺心病的诊断标准之一，其严重程度直接影响疾病的预后。

The invaded vessels were as follows: the root and /or the trunk of the pulmonary artery, the root of the superior and/or inferior pulmonary vein,and SVC and/or tho innominate vein.

受侵血管包括肺动脉根部和肺动脉干、上肺静脉和下肺静脉根部、SVC和无名静脉。

Objetive To discuss the value of spiral CT and Multispiral CT pulmonary angiography in the diagnosis of pulmonary embolism and it,s clinical used.

G$FTNCut0 ［摘要］目的：探讨螺旋CT肺动脉造影、多层螺旋CT肺动脉造影对肺栓塞的诊断及临床应用价值。

In the patients of obliterative pulmonary hypertension E/A and DT were normal but IVRT prolonged obviously.

肺血管疾病所致的肺动脉高压和原发肺动脉高压患者二尖瓣血流频谱为 E峰 A峰呈正常比例， DT正常，左室 IVRT明显延长。

Reslut: In 35 patients, some imagines such as patchy consolidation, ground glass opacity, wedge shaped shadow,"mosaic oligemia" etc can be seen on plain CT, On contrast enhancement CT scan, the central pulmonary embolism and the peripheral pulmonary embolism ect can be seen clearly.

结果：35例平扫显示片状实变影，磨玻璃样影，楔形变等。增强扫描能清晰直观显示中央型肺动脉栓塞，周围型肺动脉栓塞等。

Risk factors of mortality by univariate analysis were: outborn babies, resuscitation before admission, first born baby, low pH, high oxygen index, high alveolar- arterial oxygen tension gradient (AaDO2) at admission, high Of and AaDO2 at 2 hours after admission, shock, pneumothorax, asphyxia, pulmonary hemorrhage, persistent pulmonary hypertension of newborn, and renal failure. Logistic regression analysis showed asphyxia, pneumothorax and PPHN are the most important risk factors of mortality in MAS. How to diminish these events is the key point for reducing the mortality rate of MAS.

又变项分析显示，死亡危险因子包括院外出生婴儿，黑心诊时需急救，第一胎，刚入院时的Ph、OI、AaDO2，住院后2小时的OI、AaDO2，休克、气胸、室息、肺出血、新生儿肺动脉高压；回归分析则显示窒息，气胸及新生儿肺动脉高压是死亡的危险因子，如何减少这些事故，将是降低便吸入症候群死亡的重要因素。

Two hundred 16-day-old of age commercial broiler chickens were randomly divided into 4 groups as follows: 50 birds were exposed to normal temperature (20℃) and peritoneally injected with normal saline as control group; 50 birds were exposed to low temperature (7-9℃) and peritoneally injected normal saline as low temperature group; 50 birds were exposed to low temperature and peritoneally injected with low dose BQ123 as low temperature low dose BQ123 group; 50 birds were exposed to low temperature and peritoneally injected high dose BQ123 as low temperature high dose BQ123 group.

本试验采用高选择性ETA受体拮抗剂BQ123预处理低温肉鸡，探讨ET在低温诱发AS模型的肺血管重塑和肺动脉高压发生发展中的作用。200只16日龄AA肉鸡随机均分为4组：常温(20℃)对照组、低温(7～9℃)对照组、低温低剂量BQ123组和低温高剂量BQ123组。23日龄、30日龄时进行肺动脉压的测定，肺组织取材、石蜡切片，Weigert间苯二酚复红染色。

The up-regulation of pulmonary and plasm PAMP expression might be involved in the development of high pulmonary blood flow-induced pulmonary hypertension.

肺动脉和血浆PAMP表达的上调可能参与了高肺血流性肺动脉高压的形成。

The loss of normal lung parenchyma leads to pulmonary hypertension that leads to thickening of the small arteries along with reduplication to form a plexiform lesion, as seen here in a peripheral pulmonary artery.

正常肺实质的损伤可导致肺血管的压力增高，在此切片肺动脉的周边部可见肺内小动脉的管壁增厚，管腔狭窄引起肺动脉血压增高。

The loss of normal lung parenchyma leads to pulmonary hypertension that leads to thickening of the small arteries along with reduplication to form a plexiform lesion, as seen here in a peripheral pulmonary artery.

正常肺实质破坏引起肺动脉高压，使小动脉组织增生变厚，形成丛状病变，就如图所见的外周肺动脉分支。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
