主动脉

A thorough family history should be taken because many cardiac disorders( eg, coronary artery disease, systemic hypertension, bicuspid aortic valve, hypertrophic cardiomyopathy, mitral valve prolapse) have a heritable basis.

很多心脏疾病冠状动脉疾病(AD全身性高血压、叶主动脉瓣疾病、厚型心肌病、尖瓣脱垂有遗传基础，因此应收集详尽的家族病史。

Approximately 1% of all infants born alive in the US have bicuspid aortic valves.

在美国，大约有1%的新生儿出生时为二叶主动脉瓣。

An aortic valve need not be bicuspid to calcify.

主动脉瓣并非是两个瓣叶的才钙化。

Mechanical stress is distributed abnormally across the two cusps of these bicuspid valves causes them to "wear out" earlier than expected.

机械应力在这种二叶主动脉瓣的分布异常，导致了瓣膜的"磨损"早于预期。

The most valuable role that CMR plays in patients with valvular heart disease is in determination of left and right ventricular function with a lesser role for precise identification of valve anatomy such as identification of bicuspid aortic valves, vegetations, etc.

CMR在瓣膜性心脏病患者中发挥的最有价值的作用就是测定左，右心室功能，较有价值的作用就是精确鉴定瓣膜的解剖，如二叶主动脉瓣、赘生物等。

The terminal branches of the aorta are the common iliac arteries, which themselves then bifurcate into external and internal branches.

主动脉的末端分支就是两条髂总动脉，它们自己又分支成为髂外和髂内动脉。

目的：观察玉米苞叶煎剂对食饵性高血脂大鼠主动脉内皮细胞凋亡的干预作用及血清NO、ET水平的影响。

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。
