肺动脉

To evaluate the difference of position and morphometry of pulmonary artery and vein of isolated pig lung , through making cast specimens .

对离体猪肺的肺血管进行铸型标本制作，评估解剖所见的肺动脉和肺静脉走行位置及形态学情况。

Purpose To evaluate the right ventricular function by dynamic three-dimensional reconstruction of multiplane transesophageal echocardiography with voxel imaging.

目的 建立多平面经食管体元模型动态三维重建超声显像测定右心功能的方法，评价肺动脉高压对右心室形态和功能的影响。

Methods by means of mri and echocardiography, 52 cases in the research group underwent the measurement of ventricular septal defect, pulmonary artery and left ventricle, by which mcgoon ratio, nakata index and the index of left ventricular diastasis would be given out. in order to determine the operative indication, the outcomes of the calculation were judged comprehensively, according to which tof operative indication and prognosis were estimated. their results were also compared with the outcomes of the measurement during the operations.

本组52例患者均为tof，所有病例均通过mri和超声心动图检查，分别测量室间隔缺损、肺动脉和左心室，计算mcgoon比值、nakata指数和左室舒张末期容积指数，进行综合判断、选择手术适应证及估计预后，并与手术测量结果对照。

Early in the disease process, the signs and symptoms of PAH are often nonspecific, making diagnosis challenging.

在疾病的早期，肺动脉高压的症状和体征常常是缺乏特异性，难于诊断。

It is also possible to have multiple small pulmonary thromboemboli that do not cause sudden death and do not occlude a large enough branch of pulmonary artery to cause infarction.

当然也有可能有多个小血栓，但不引起猝死，因为没有堵塞大的肺动脉分支，也就不引起梗死。

The isolated rat lung can be used as oxygenator instead of a mechanical oxygenator in the rat CPB model.

离体大鼠肺能够作为氧合器用于CPB研究，大鼠CPB中肺动脉灌注肺保护液在方法上是可行的。

The purpose of this review is to describe the current state of evidence for the diagnosis, prognosis, and treatment of the patient with PAH.

本次综述的目的是要讲清楚肺动脉高压的诊断预后和患者的治疗方面目前的研究情况。

TNF-α antagonists may be useful in the management of connective tissue disease associated PAH.

TNF-α拮抗剂对治疗合并肺动脉高压的结缔组织病可能是有效的。

The prevalence of PAH is 15 per million in the French registry.

在法国根据登记在册的情况来看每一百万人中有15个患有肺动脉高压。

ApoE deficiency leads to enhanced platelet-deried growth factor signaling, which is important in the pathobiology of PAH.

ApoE缺陷可以导致血小板衍生的生长因子信号系统增强，后者在肺动脉高压的病理中占重要地位。

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。
