Results The steno-occlusive type was most common (73.9%) in aortitis syndrome. According to the classification of Lupi-Herrea, type Ⅲ was observed in 43.5% of all. Left subclavian arteries (69.6%) and left common carotid arteries (60.9%) were the most frequently involved.

结果 大动脉炎综合征病变以狭窄-阻塞型最常见（73.9%），按Lupi-Herrea分型以Ⅲ型多见（43.5%），最常受累的血管为左锁骨下动脉（69.6%）及左颈总动脉(60.9%)。

The primary end point was binary restenosis at 1-year angiographic follow-up.

Experimental methods: pathological slices: To observe the changes of pathomorphology and measure the circular area of internal elastic lamina , area of neonate intima and vascular lumen, the intimal proliferatory index and percentage, the index of lumen stenosis and positive index of proliferating cell nuclear antigen through the specimens stained by HE and immunohistochemistry.

实验方法：病理切片：进行HE染色和免疫组织化学染色，分别观察病理形态学改变；测定和计算受损血管内弹力膜环绕总面积、新生内膜面积、管腔面积、内膜增生指数、内膜增生百分比、管腔狭窄指数和增殖细胞核抗原阳性指数；观察MMP-2、MMP-3、TIMP-1和PDGF-BB的免疫组化表达。

Sympathetic activity increases, the heartbeat is added fast, cardiac muscle oxygen demand increases; Also can make plaque produces conglutinate to gather each other, release shrink hemal material, make already narrow coronary artery produces convulsion, cause angina pectoris show effect.

交感神经活动增强，心率增快，心肌耗氧量增加；也可以使血小板相互发生粘附聚集，并释放缩血管物质，使已经狭窄的冠状动脉发生痉挛，导致心绞痛发作。

Methods On the operation process of the 15th patient suffered actual anal scar straitness deformity, We have designed an axial pattern skin flap whose axes is inferior rectum artery branches or scrotum, and the crissum wound caused by excising scar with ring coverage.

Background— Multidetector computed tomographic angiography has been shown to allow detection of coronary artery bypass graft occlusions and stenoses.

背景：多控测器CT血管造影术已经能检测出冠脉搭桥术后的血管闭塞和狭窄。

These include: the pre-VAD insertion examination of the heart and largevessels to exclude significant aortic regurgitation, tricuspidregurgitation, mitral stenosis, patent foramen ovale, or othercardiac abnormality that could lead to right-to-left shunt afterleft VAD placement, intracardiac thrombi, ventricular scars,pulmonic regurgitation, pulmonary hypertension, pulmonary embolism,and atherosclerotic disease in the ascending aorta; and to assessright ventricular function; and the post-VAD insertion examinationof the device and reassessment of the heart and large vessels.

这些包括：（1） VAD 植入前心脏和大血管的检查以排除明显的主动脉反流、三尖瓣反流、二尖瓣狭窄、卵圆孔未闭或者可能引起左 VAD 植入后右向左分流的其他心脏异常，心内血栓、心室疤痕、肺动脉反流、肺动脉高压、肺栓塞和升主动脉粥样硬化疾病；并且评估右室功能；（2） VAD 植入后检查设备及再评估心脏和大血管。
