Left ventricular,aortic and plasmic AngⅡ were higher in SHR-L than in SHR-C.

SHL-L组AngⅡ水平均高于SHR-C组，且以血浆升高最明显解答。

When the spiral septum fails to completely descend, the aortic and pulmonic trunks are left undivided at their outflow.

一旦螺旋形隔板下降不全，主动脉和肺动脉干的血流将不能分开。

They are associated with stenosis of either the aortic or the pulmonic valve, with hypertension or dilatation of either the aorta or the pulmonary artery or both.

喷射性喀喇音喷射性喀喇音音调高，出现于收缩早期，与主动脉瓣或肺动脉瓣狭窄有关，也与主动脉瓣或肺动脉瓣或两者的高血压或膨胀有关。

The most common causes are aortic or pulmonic valve regurgitation.

其强度提示瓣膜泄漏面积、胸腔声学特征、及穿过瓣膜的压力差异。

Tricuspid regurgitation was most commonly found and was detected in417(45.8%) children, pulmonic regurgitation in225(24.7%), mitral regurgitation in12(1.3%), and aortic regurgitatioin in5(0.5%).

结果495名有一组或一组以上的心脏瓣膜返流，发生率为54.4%三尖瓣返流最常见，有417名5.8%；肺动脉瓣返流次之，有225名(4.7%；二尖瓣、动脉瓣返流少见，分别有12名。3%和5名

However, BH4 stopped subsequent remodeling when NOS activity was otherwise declining. A broad antioxidant, Tempol, also reduced oxidant stress yet did not recouple NOS or reverse worsened hypertrophy/fibrosis from sustained transverse aortic constriction.

然而，在NOS活性降低时BH4阻止心脏的继续重构，广义的抗氧化剂，Tempol也可以在保持主动脉缩窄的情况下，NOS没有恢复偶联或逆转心脏肥厚或纤维化，降低氧化应激。

Subsequently, management in these patients includes life time medical treatment to minimise aortic wall stress, serial imaging to detect signs of dissection progression, redissection, or aneurysm formation, and endovascular or surgical intervention when needed.

因此，对这些患者的治疗包括终生药物治疗以减少主动脉管壁压力，定期影像学检查以早期发现夹层进展、再次夹层或动脉瘤形成的征象，并在必要时进行血管内介入或开放手术治疗。

Objective To compare the relationship between measurement of the time constantly derived from aortic regurgitant velocity spectra and catheter derived time constant, and to evaluate the effects of hemodynamic flow states and regurgitant volumes on the Tau AR.

目的 对比研究由主动脉返流频谱得到的时间常数Tau和心导管根据左室压力曲线得到的时间常数的相关性，评估血流动力学参数和返流容积对Tau－AR的影响。

The options of treatment for abdominal aortic aneurysm include traditional procedures and endovascular aneurysm repair.The reintervention rate is higher in EVAR than in traditional procedures.

腹主动脉瘤传统手术及腔内修复术后的再手术应根据不同原因采取相应策略，腔内修复较传统手术有较高的再次干预率。

In 12–30% of patients, repeated repair or reintervention is required because of extension or recurrence of dissection at the previous site of intervention, localised aneurysm formation remote from the site of repair, graft dehiscence, aortic regurgitation, or infections.34 Because of the predilection for the diseased aorta to become aneurysmal at a location distant from the area of dissection, imaging of the entire aorta is advised.

12–30%的患者因出现手术部位夹层进展或再夹层、病灶远处局部动脉瘤、人造血管破裂、主动脉反流或感染而需要再次行修补或介入术。正因为易于在远离夹层的部位出现动脉瘤，要求影像学检查必须包含整个主动脉。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
