The model well mimicked the hearts in vivo. Perfusions were performed at a constant 1. 5kPa left atrial preload and 10.7kPa aortic afterload.

该模型较好地模拟了在体心脏做功时的工作状态，使左心房前负荷保持在1.5kPa，主动脉后负荷保持在10.7kPa。

Objective: To investigate into the effect of tea polyphenols on the microvessel structure of rat aorta to provide pre-experimental data for the research of the mechanism of tea polyphenols in preventing tumor angiogenesis factor.

目的：开展茶多酚对大鼠主动脉微血管样结构影响，为其抗肿瘤血管生成分子机制研究提供实验资料。

The coronary artery orifices can be seen just above.

Methods Blood samples of fifty-two patients who underwe n t open heart surgery with CPB were collected from right internal jugular vein at p oints as pre-CPB, rewarming, aortic declamping, 6 hours and 24 hours after CPB. Cytokines, iNOS, S-100 and NSE were assayed accurately. In addition, its corre lation between them were also analysed.

方法于 CPB前、复温即刻、主动脉开放和 CPB后 6、2 4小时采集 5 2例心脏病患者颈内静脉血，检测 S- 10 0蛋白和 NSE的浓度，并将其与炎性细胞因子白细胞介素- 6 (IL- 6 )、白细胞介素- 8(IL- 8)、肿瘤坏死因子-α和诱导型一氧化氮合成酶的浓度变化进行相关性分析。

Pressure release: The pressure on the chest is released, allowing the pulmonary vessels and the aorta to re-expand causing a further initial slight fall in pressure (20 to 23 seconds) due to decreased left ventricular return and increased aortic volume, respectively.

压力舒缓：胸部压力舒缓，促使肺血管与主动脉重新扩张，左心房的血液量增加且大动脉血量增加而造成一开始血压降低(20-23秒)。

METHODS From May 2004 to Feb 2005, 40 mitral valve disease or double valve cases underwent valve replacement in shanghai chest hospital randomly enrolled in this study, randomly separated into two groups, 20 cases each..

2004年5月至2005年2月，二尖瓣置换术或二尖瓣与主动脉瓣联合置换术的患者40例，每组20例；对照组不做任何形式的超滤；试验组ECC中行零平衡超滤，超滤量约60 ml/kg，平均3 417 ml／人。

The lfMRI with SE sequence and/or GR sequences can be used to display the true-false cavities and the endomembranous pieces of aortic dissection.

所有序列对内膜破口和再破口的显示效果不佳，对主动脉主要分支受累情况显示也不满意。

The true and false cavities of aortic dissection could be displayed on the SE T1WI,T2WI for the B type in 10 of 12 cases.With SE sequence,the true-false cavities did not be showed but the endomembranous pieces could be seen for A type of 2 cases of aortic dissection.

对于SE序列不能区别真假腔的2例A型夹层，轴位T1WI可显示剥离的内膜片。2例主动脉迂曲形成涡流的B型夹层，T1WI和T2WI不能区别真假腔，也不能显示内膜片，加行GR序列轴位扫描，可清晰显示等信号的内膜片。

Along with the rapid development of building industry, tier and high buildings in big and middling cities have been increasing, the tower crane has been the main construction machine in the upright transportation of tier and high buildings.

随着建筑业的不断发展，各大中城市多层和高层建筑不断增多，塔式起重机已成为多层和高层建筑施工垂直运输的主动脉。

Object: To test the feasibility and safety of stent-graft in treatment of aortic dissection and penetrating ulcer.

探讨支架型人工血管介入治疗主动脉夹层动脉瘤及穿透性溃疡的适应证及疗效。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
