Percutaneous pulmonary and aortic valve implantation to treat the respective valvar regurgitations are innovative new applications of stent that have gained initial success.

经皮置入带有支架的肺动脉或主动脉瓣膜治疗瓣膜反流是一个新的尝试，已获得初步成效。

Lead two considerable ducts or ureters into the bladder; and othersspring from the aorta, strong and continuous. And to the middle of

从这个腔开始延伸出两条相当宽的输尿管进入膀胱，其他的从主动脉来，强壮而且持续。

She will need to have an echocardiogram repeated in the first, second and third trimesters to monitor the size of her aorta.

她将需要有一个反复超声心动图，在第一次，第二次和第三次晚期监测的大小，她主动脉。

The proliferation detected using MTT method, the DNA synthesis was evaluated by -thymidine incorporation in cultured cells.

实验用不同组大鼠主动脉制备离体培养平滑肌细胞，用MTT法分析细胞增殖，用-TdR掺入法分析细胞DNA合成。

Material and methods:? Dynamic Observation Group:The rabbits were anesthetized with thiopental .

研究温控导管射频消融主动脉根部即时损伤深度与温度、时间的相关性。

METHODS From July 2000 to March 2005,14 patients received off－pump aortic arch aneurysm surgery. Of these patients,5 were subjected to total aortic arch replacement, 6 partial aortic arch replacement and 3 total aortic arch replacement combined with transaortic stented graft implantation into the descending aorta or partial descending thoracic aorta replacement.

14例患者在常温非体外循环全身麻醉下实施主动脉全弓或部分弓置换术，其中男12例女2例，主动脉弓降部假性动脉瘤12例，先天性弓部动脉瘤2例。

Heart malformation, such as PTA, DORV, VSD and aortic arch malformation, were detected when neural crest were taken out before they migrated into 3, 4, 6 pharyngeal gland. Interestingly, the types of malformation were related with the length of neural crest destroyed; PTA was detected if the length exceeds two somites, while DORV would be detected if the length less than two somites. These results indicate that CNCCs are very important to the conotruncal development.

研究发现，如果在迁移之前切除散发到第3、4、6咽弓的神经嵴细胞，就会出现永存动脉干、主动脉骑跨、右室双出口、主动脉弓畸型和室间隔缺损等心血管畸形，且切除的长度与畸形的种类相关，如切除长度大于两个体节可产生永存动脉干，切除长度小于两个体节则产生右室双流出道，由此可见，心脏神经嵴细胞对于心脏圆锥部的发育意义重大。

Methods 42 cases mature neonate with MSCT scanning in lung were collected and randomly divided into three groups averagely. The tube current was 50 mAs and 30 mAs for low dose scanning and 200 mAs for routine dose. The CT value of region of interesting and standard deviation were measured in the aorta that region of carina of trachea. And compared the noise, image quality, CT dose index and dose length product between two low-dose scannings and routine dose.

42例足月新生儿随机等分成3组分别行低剂量30mAs、50mAs及常规剂量200m AsMSCT胸部扫描，统一于气管分叉处测量并记录主动脉CT值及标准差，比较两低剂量扫描与常规剂量扫描的噪声、图像质量、CT剂量指数和剂量长度乘积等差别。

In the SMC of the normal rabbits, myofilaments and macula densa were abundant, few mitochondrla and endoplasmic reticulums were found around the nuclear, and the SMC was in the contractive stage. In the SMC of the model rabbits, few myofilaments and macula densa were found, rough surfaced endoplasmic reticulums and mitochondria were abundant, some phagocytosed much lipid and became foam cells, the SMC was in the synthetic stage.

实验12周，高脂组家兔主动脉斑块面积百分比为47.69±12.84％，内膜斑块厚度为0.68±0.08mm，内膜斑块横断面积与中膜面积比值为1.28±0.35；内膜脂质斑块弥漫且较厚，有大量的泡沫细胞堆积，可达8～10层，管腔直径变小，内膜不光滑；泡沫细胞内富含脂滴，呈椭圆形气球样，有的斑块中可见显著的平滑肌细胞增生及大量的弹力纤维形成。

Once the position of the device was found to be satisfactory and without or with only a trace to small residual shunt was confirmed, the device was released by turning the cable counterclockwise using the pin vise.

选择大于所测PDA最窄直径2～4 mm的Amplatzer封堵器，于透视下经6 F输送鞘管将其封堵于PDA处。10分钟后重复主动脉造影，若封堵器形状、位置满意，无或仅有微～少量残余分流时，可释放封堵器。

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。
