肺动脉

The relationship of pulmonary artery to the lung lesion and degree of pulmonary arterial encasement could be used in differentiating benignancy from malignancy not only for central lung lesions but also peripheral lung lesions and this would decrease biopsy rate.

利用肺动脉及肺部病灶之间的关系以及利用肺动脉被包埋压迫的程度可以用来鉴别肺部病灶是良性病灶或是恶性肿瘤。

Methods the rabbit arterial smooth muscle cells were cultured ex vivo, cells of 4-7 generation were divided into groups interfered with ang-（1-7）, positive control groupsinterfered with ang-ii(10-6mol/l) and blank control group .cell counting with trypanblau dying and mtt were used to evaluate the growth of cells in different groups and results were compared .

体外培养兔肺动脉平滑肌细胞，鉴定后传代培养，取4～7代细胞，应用不同浓度ang-（1-7）干预，并与血管紧张素-ii(ang-ii，浓度10-6mol/l)、空白组对照。通过台盼蓝染色法细胞计数、四甲基偶氮唑蓝比色法，确定肺动脉平滑肌细胞的生长趋势变化。

Therefore, the purposes of this paper are on, firstly, the possible difference of secret of vasoactive substances from pulmonary artery and aortic artery endothelial cells; secondly, the regulatory effect of pulmonary microartery endothelial cella on the movement of pulmonary artery.

所以本文的研究目的为：1研究肺动脉内皮细胞和主动脉内皮细胞分泌血管活性物质的可能差异：2研究肺微动脉内皮细胞对肺动脉血管运动的调节作用；此外，基于我室以往对吸烟和肺血管反应性的研究。

The aim of this study is to evaluate the ability of the relationship between pulmonary artery and lung lesion to distinguish benign lung lesion from malignancy and the degree of pulmonary arterial encasement in predicting malignancy is evaluated with receiver operating characteristic curve.

这研究的目的在评估利用肺动脉及肺部病灶之间的关系来鉴别肺部病灶是良性或恶性之能力以及利用接受者操作特徵的曲线来评估肺动脉被包埋压迫的程度用在预估恶性病灶之能力。

The dissecting of samples in group2 were difficult. The root of pulmonary artery and ascending aorta failed to be unfolded because fibrous tissue was tough, right and left fibrous trigone were too firm to be solved by hand. Cardiac muscle fibers couldn't be stripped along myofibrillar trajectory since they were prone to break because of their friability.

组2的心脏解剖困难，表现为纤维组织坚韧，游离肺动脉非常困难；徒手无法松解左、右纤维三角，肺动脉和主动脉根部的游离非常困难；心肌纤维坚硬、质脆，解剖时容易断离成碎块，无法沿纤维走行方向剥离。

Pulmonary homograft - a section of the child's own pulmonary artery with the valve intact is used to replace the aortic valve and a section of the aorta.

Results: The pulmonary artery wall of RHD group become more incrassate than that of the control group.

结果：RHD患者肺动脉的结构发生明显改建，RHD及对照组肺动脉内都有增殖与凋亡的细胞，但RHD组增殖细胞多而凋亡细胞明显减少。bcb2在RHD组中表达强度明显高于对照组，而bax在对照组中的表达高于RHD组。

However, the right ventricule has a crescentric shape, with a separate infundibulum and prominent trabeculations, it is difficult to describe the right ventricule by a simple geometric figure and therefore, difficult to assess its function in a conventional two-dimensional echocardiography.

另 卜，肺动脉高压（Pulmon叼 hypertension，PH）是左向右分流型CHD如ASD常见的并发症之一，PH的存在与否及其严重程度与先心病治疗决策、手术疗效及临床预后密切相关，但先心病合并肺动脉高压的发病机理仍不清楚，尚待进一步研究和探讨。

Objective To explore the modified pulmonary to aortic flow time interval ratios in quantitative estimation of pulmonary arterial pressures.

目的 探讨改良的肺动脉/主动脉血流时间间期比定量估测肺动脉压的新方法。
