肺动脉

Simultaneous measurement of CORB and COTD were performed in following situations:(1)cardiac output was varied by manipulating inotropic drugs(adrenine, dobutamine, dopamine, verapamil);(2)under six different ventilatory settings:①volume controlled ventilation with tidal volume of 12ml/kg(VCV, VT 12ml/kg);②volume controlled ventilation with tidal volume of 6ml/kg(VCV, VT 6ml/kg);③pressure controlled ventilation with tidal volume of 12ml/kg(PCV, VT 12ml/kg);④pressure controlled ventilation with tidal volume of 6ml/kg(PCV, VT 6ml/kg);⑤volume controlled ventilation with high positive end-expiratory pressure.

1经肺动脉漂浮导管CVP腔注射肾上腺素、多巴酚丁胺、多巴胺、异搏定改变动物心肌收缩力，观察注射药物前、注射药物后CORB和COTD的相关性；(2)设置5组不同的机械通气参数：①容量控制通气，潮气量12ml/kg(VCV， VT 12ml/kg)；②容量控制通气，潮气量6ml/kg(VCV， VT 6ml/kg)；③压力控制通气，潮气量12ml/kg(PCV， VT 12ml/kg)；④压力控制通气，潮气量6ml/kg(PCV，VT 6ml/kg)；⑤容量控制通气，潮气量6ml/kg，高呼气末正压，PEEP为12~15cmH2O。

Objective To evaluate the value of spiral computer tomography angiography in the diagnosis of pulmonary embolism.

目的评价螺旋CT血管造影对肺动脉栓塞的诊断价值。

Abstract］ Objective To evaluate the value of CT pulmonary angiography in diagnosis of embolism.

目的 评价CT对肺动脉栓塞的诊断价值。

Results: The pulmonary arteries could be recognized in CVH images and reconstructed. The three-dimensional images perfectly show the brunches of the pulmonary arteries, even the subsubsegmental arteries were able to be recognized. Conclusion: The research reconstructed and visualized the pulmonary arteries of the first Chinese Visible Human.

结果：CVH肺脏断面图像清晰，可清楚显示肺动脉系统，分割后重建出肺内动脉系统，重建图像质量较高，最远可显示肺动脉的第5级分支。

It might be concluded that during the early period of the oxygen deficiting, the activeness of NOS elevates, thus causes the NO level elevate, this diastoles the vessel, alleviates the high pressure of pulmonary artery, is one kind of body stress reaction.

本实验研究显示，对于发生肺动脉高压综合征的肉鸡，在处理后1周、2周时，肺动脉高压综合征肉鸡组的肝脏、心肌和肠粘膜线粒体的Na~+-K~+—ATPase。

These include: the pre-VAD insertion examination of the heart and largevessels to exclude significant aortic regurgitation, tricuspidregurgitation, mitral stenosis, patent foramen ovale, or othercardiac abnormality that could lead to right-to-left shunt afterleft VAD placement, intracardiac thrombi, ventricular scars,pulmonic regurgitation, pulmonary hypertension, pulmonary embolism,and atherosclerotic disease in the ascending aorta; and to assessright ventricular function; and the post-VAD insertion examinationof the device and reassessment of the heart and large vessels.

这些包括：（1） VAD 植入前心脏和大血管的检查以排除明显的主动脉反流、三尖瓣反流、二尖瓣狭窄、卵圆孔未闭或者可能引起左 VAD 植入后右向左分流的其他心脏异常，心内血栓、心室疤痕、肺动脉反流、肺动脉高压、肺栓塞和升主动脉粥样硬化疾病；并且评估右室功能；（2） VAD 植入后检查设备及再评估心脏和大血管。

Cellular growth, constrictions function and free Ca2+ in cultured pulmonary artery smooth muscle cells were measured by the methods of MCT, morphometry and calcium fluorescent probe Fura 2-Am.

肺动脉和体动脉不同，对5-HT的缩血管效应比对去甲肾上腺素的更敏感。对5-HT在不同原因形成的肺动脉高压中的作用要做具体分析。

Pulmonary hypertension in healthy highlanders is related to a delayed postnatal remodeling of the distal pulmonary arterial branches.

健康的高地人出现肺动脉高压与后天迟发性肺动脉分支末梢血管重构有关。

The morphological data, valvular function, left ventricular systolic function and hemodynamic parameters of HHD and NS were studied.

结果 HHD患者 82 。7%有不同程度房室腔扩大，左室收缩功能大多正常或高于正常；88%HHD存在瓣口返流，其中二尖瓣、三尖瓣中重度返流；14例HHD患者有瓣膜增厚，2 7例可见二尖瓣脱垂；肺动脉增宽和肺动脉高压发生率分别为62 。6%和 73 。3 %。

Results Among 73 patients with HHD, there were 82.7% with cardiac enlargement, but the majority of their left ventricular systolic func...

HHD可引起不同房室腔扩大，左房扩大最常见，右室扩大多于左室扩大；HHD常合并瓣膜反流，部分患者瓣膜增厚；肺动脉增宽和肺动脉高压是HHD的普遍现象。

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。
