The representative characteristic of the gland is that its intima and media are not ring form like those of general blood vessels but reculodromous and they extend to ducts cavity from different places and join each other to form tortuose reticulated vessels which have different shapes and sizes in diameter.

颈动脉腺的最大特点是中膜和内膜并不像一般血管形成环圈状，而是从不同部位向管腔突出延伸、相互连接构成大小不一、形状各异、迂回曲折的网状血管。

After administration of L-N〓-nitro-Arginine, a specific antagonist of NOS, it was found that the basal and stimulated NO release of blood vessels (aorta, internal carotid, renal and mensenteric artery) was decreased further. The increase of coronary blood flow stimulated by Ach was also reduced further, while the platelet aggregation degree and erythrocyte aggregation index increased significantly. Pathological examination indicated that aortic endothelium was destroyed, the blood vessels in cerebral, cardiac and renal tissues were hypertrophied further and some were almost occluded. The above fin dings resulted in SHR feeded with L-NNA having high incidence of stroke rate and high degree of renal cirrhosis when compared to control SHR. The infarct and hemorrhagic focuci in cerebral tissues, infarct focuci in cardiac tissues, atrophy and hyalinedegeneration of renal glomeruli and degeneration even necrosis of renal tubuli in renal tissues were al so found. The increase ratio of brain and heart to body weight and decrease ratio of kidney to body wei ght further demonstrated that the cerebral, cardiac and renal injuries were aggravated.

在上述结果的基础上进一步给予SHR NOS特异性拮抗剂左旋亚硝基精氨酸后，血管(胸主、颈内、肾及肠系膜动脉)NO基础释放及激动剂刺激释放进一步减少，Ach刺激冠脉流量的增加和胸主动脉内膜NOS活性也进一步减少，血小板聚集程度及红细胞聚集指数显著上升，病理切片显示胸主动脉内皮细胞破坏明显，脑心肾组织内的血管进一步增厚甚至几乎阻塞，导致饲L-NNA的SHR缺血性及出血性脑卒中发生率显著高于对照SHR，脑体重比显著升高；心肌内出现明显的缺血梗塞疤痕灶，心体重比显著升高；肾小球明显萎缩、玻璃样变性，肾小管也变性甚至坏死，使肾硬化程度显著增加呈颗粒性固缩肾，肾体重比也显著减少。

Though the primary stimulator of 1H is not clear, it is related to physical, cell and body fluid IH is a chronic process involving multiple faction injury and blood flowing abnormal are revamped as the main reason, the proliferation level depend on the length and width of the injure of vessel large amount research illustrate injury cause many growth factor infolded in IH, for example: template derived growth factor, fibroblast growth factor, transmission growth factor , endothelin (ET-1) et al, some early responsive gene such as c-fos、c-jun c-myc also take part in SMC proliferation after vessel injury.

虽然IH的确切起始刺激因子并未阐明，但已知与物理、细胞和体液因子有关。IH是一个多因素参与的慢性过程，损伤和血液动力学异常一真被认为是IH的主要因素。内膜增殖的程度有赖于血管损伤的长度和深度。近年来大量的实验研究结果表明，损伤等刺激引起的众多的生长因子样物质在IH中起关键作用。如血小板源性生长因子、碱性纤维母细胞生长因子、转化生长因子β、内皮素-1（ET-1）等诸如C-fos、C-jun、C-myc等早期应答基因也参与了血管损伤后SMC的增殖。

Results: l、The optimal scan parameters for chinese people are flow rate of 3. 0 mL/sec and total injection 125ml. 2、Visibility of coronary arteries and segments: only those proximal and mid segment is image quality sufficient to allow a semiquantitative assessment. 3、Detection of Atherosclerotic Plaque: CT coronary imaging revealed highest sensitivities for the detection of atherosclerotic wall changes the sensitivity of stenoses was 86. 3％. 4、MSCT coronary angiography is easy to prove the entire anatomic structure of coronary and it is an effective technique for evaluating coronary patency. 5、MSCT coronary angiography correctly identified all normal controls and all patients with coronary artery fistula. The anatomic course of the coronary artery fistula was correctly classified. 6、A11 severe lesion could be visualised by

结果：1、不同的扫描技术参数所获得的造影图像质量不同，注射速率3.0ml/s组以及125m1对比剂总量组比较适合国内患者。2、多层螺旋CT冠状动脉造影可显示冠状动脉的主要分支，尤其是冠状动脉的近、中段，显示率在90％以上。3、多层螺旋CT冠状动脉造影对狭窄病变的敏感性为87.3％，能检出冠状动脉造影不易发现的细小斑块，判断狭窄的原因及斑块的特征。4、多层螺旋CT冠状动脉造影可显示搭桥血管的形态、位置及通畅程度，显示桥血管及支架的内腔，安全便捷。5、多层螺旋CT显示冠状动脉畸形准确性高（3/3），多种成像方法可弥补冠状动脉造影显示的不足。6、仿真内窥镜可显示冠状动脉内膜和内腔，显示狭窄斑块的性质。

The co-eluting stent, sirolimus-eluting stent and bare-metal stent were implanted into porcine coronary artery model of sac expansion; 28 days later, the neointirnal area, mean neointimal thickness and reendothelialization of the stented coronary arteries were analyzed.

在猪冠状动脉球囊扩张模型中，植入雷帕霉素／雌二醇复合洗脱支架、雷帕霉素洗脱支架和裸支架，术后28 d考察支架血管段新生内膜面积、内膜平均厚度及支架内皮化程度。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
