Pregnant 50 day onward, FOXC2 mainly expressed in dorsal aorta, arch arteries, archae-endocardium and cells of vertebrae rudiment. The expression of FOXC2 could be seen in cordis great vessels, endocardium, chondrocyte and periost of axial skeleton during pregnant 70 days, and only in primary ossification center of axial skeleton and coronary artery during pregnant 80 day.

孕50天后表达于背主动脉、弓形动脉和原始心脏内膜、锥体雏形细胞；孕70天时，在心脏大血管、心内膜和中轴骨骼的软骨细胞和骨膜细胞表达；孕80天时仅表达于中轴骨骼的骨化中心和冠状动脉。

Uterine obstruction of venous return can produce prearrest hypotension or shock and in the critically ill patient may precipitate arrest.1,2In cardiac arrest the compromise in venous return and cardiac output by the gravid uterus limits the effectiveness of chest compressions.

在怀孕20周以后，妊娠子宫挤压下腔静脉和主动脉，使静脉回流和心输出量受阻。子宫静脉回流受阻会导致停跳前高血压或休克，对病情危重的患者促进心跳停止[1，2]，同时，妊娠子宫还限制肺的舒张。

As a result, the outflow of right ventricle is into the aorta and the outflow from the left ventricle is into the pulmonic trunk.

结果导致右心室的血流进入主动脉而左心室的血流则进入肺动脉。

It is characterized by a connection between the aorta and the pulmonary artery which allows oxygen-rich blood that should go to the body to recirculate through the lungs.

在主动脉和肺动脉之间（存在出生后本来应该关闭）的连接通道是其特点，政造成富含氧的鲜红色血液未能进入全身循环，而是经过此通道再次回流到肺部，。

It is characterized by a connection between the aorta and the pulmonary artery which allows oxygen-rich blood that should go to the body to recirculate through the lungs.

在主动脉和肺动脉之间（存在出世后本来应该关闭）的连接通道是其特点，政造成富含氧的鲜红色血液未能进入全身循环，而是经过此通道再次回流到肺部，。

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。

Methods:Single guinea pig ventricular myocytes were obtained by retrogradely perfusing with collagenase through the aorta.

用主动脉逆向灌流法酶解分离得到单个豚鼠心室肌细胞，在倒置显微镜下，选择质膜完整、横纹清晰的心室肌细胞，利用膜片钳技术经过封接、破膜、电容及串连电阻的补偿形成膜片钳全细胞记录状态。

Onclusions-: Radial artery aortocoronary bypass grafts to a stenosed branch of the circumflex coronary artery have an excellent patency rate at 5 years.

在五年中桡动脉主动脉冠状动脉旁路移植对狭窄的冠状动脉具有优良的通畅率。

METHODS: Differences of the vasodilating action of Ipt in big artery and small artery were studied using isolated rat tai l artery helical strips and aortic rings, and the effects of Ipt on potassium cu rrents in smooth muscle cells derived from rat tail artery were observed by usin g patch clamp technique.

采用大鼠尾动脉螺旋状血管条和主动脉离体血管环两种组织，对比观察盐酸埃他卡林对大、小动脉扩张作用的药理学特性，并且利用膜片钳技术观察盐酸埃他卡林对大鼠尾动脉平滑肌细胞钾电流的影响。

This is a woundless, nonenzymatic method of obtaining highly purified primary endothelial cells of the rat aorta, especially practical for isolation and culture of small vascular endothelial cells.

此方法无损伤、不需要酶消化，能比较容易的获得高纯度大鼠原代主动脉内皮细胞，适用于细小血管内皮细胞的分离与培养。

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。
