We have firstly calculated and compared the different flow rates by applying various aliasing velocities in the patients with mitral insufficiency, mitral stenosis and ventricular septal defect as well, and suggest that the most uitable aliasing velocities for the hemisphierical flow cenvergence calculation were about 46cm/sec for mitral insufficiency, 37cm/sec for mitral stenosis and 58cm/sec for ventricular septal defect respecively.

首次在二尖瓣关闭不全、二尖瓣狭窄和室间隔缺损患者采用不同混叠极限速度分别计算、比较其流量，提出二尖瓣关闭不全、二尖瓣狭窄和室间隔缺损患者最适合半球血流会聚法计算流量的混叠极限速度分别为46、37和58cm/sec左右。

Of 15 stenotic coronary arteries(14 occluded) with wellestablished collateral vessels, 14 displayed high signal intensities,while of the other 25 vessels (1 occluded) without any collateral vessels, only 11 had high signal intensities within the related segments.

延迟扫描序列显示其中16例的25支(62.5%)心肌节段呈高信号。16例中11例临床诊断心绞痛患者延迟扫描阳性。15支狭窄冠状动脉(11支闭塞)有侧支循环形成，延迟扫描显示14支相应心肌节段阳性；25支狭窄冠状动脉(1支闭塞)无侧支循环，11支相应心肌节段呈高信号，两者延迟扫描阳性率差异有显著性意义(Fisher精确检验P＜0.001)。

随着保护技术的应用和防止再狭窄技术的成熟，介入治疗将在颈动脉狭窄治疗中发挥更大的作用。

As a result of bronchial tube distortion,narrow,causes a row of phlegm impeded to cause the trachea and the lungs repeatedly infects,creates the tube cavity to be narrow,the gas channel resistance advances,causes the oxygen deficit and the carbon dioxide remains.

由于支气管的扭曲，狭窄，导致排痰不畅使气管及肺部反复感染，造成管腔狭窄，气道阻力增高，引起缺氧及二氧化碳潴留。

In aortic stenosis, calcium deposits narrow the aortic valve and impair the heart's ability to pump blood.

在主动脉狭窄病例中，钙质沉淀使得主动脉瓣膜狭窄，损害了心脏的供血能力。

The causes of acrtic valve diseases in the three groups were analyzed. Results: Rheumatism was the most common reason, accounting for 59.7%(43 cases) of simple aortic stenosis, while bicuspid valves accounted for 23.6%(17 cases). The most common cause for aortic insufficiency was root dilation (38 patients, 43.2%).

结果：风湿性、二叶式主动脉瓣、主动脉根部扩张以及退行性主动脉瓣病变是主要的病因类型，其中单纯主动脉瓣狭窄以风湿性（43例，占59.7%）及二叶瓣17例(23.6%)病因为主，单纯主动脉瓣关闭不全以根部扩张（38例，占43.2%）为主，主动脉瓣狭窄合并关闭不全则以风湿性（70例，占88.5%）为主。

The characteristics and changes of etiology were analyzed. All cases with aortic diseases were divided into single aortic stenosis, single aortic insufficiency, and combined aortic stenosis plus insufficiency group.

分别以主动脉瓣狭窄、主动脉瓣关闭不全、主动脉瓣狭窄合并关闭不全3组分析，具体病因包括风湿性、二叶式主动脉、退行性主动脉瓣、主动脉根部扩张、感染性心内膜炎、少见及未确定等6类病因。

"In-stent restenosis of DES occurs in nearly 10% of all DES implanted oer time," senior inestigator Dr. Ron Waksman told Reuters Health."Although not diffuse as with bare metal stents, DES ISR still associated with late eents."

高级研究人员Ron Waksman博士告诉路透社健康版说：&10%的药物支架在植入一段时间后发生血管内支架再狭窄，虽然不像单纯金属支架的问题那样广泛，药物支架血管内支架再狭窄也与近期活动有联系。&
