Results All 35 cases were examined successfully with 3D DCE MRA. Anatomical position fusion of neck, chest and abdomen including blood stream signal, vessel wall and the tissue of vessel wall circumambience were clearly displayed. 3D DCE MRA can give a definite judgement to masses orientation and the circumference vessels correlate with tissue.

结果 所有病例3D DCE MRA均一次检查成功，清楚地显示了颈、胸部、腹部大血管解剖结构，包括血流信号、血管壁及其壁周组织，对病变的定位及与周围血管和组织相关性均可以作出明确的判断。

Anatomical study proved:①.4~8 nutritional vessels of sural nerve –small saphenous vein were the intermuscular perforators of peroneal artery, the furthermost one located at(1.0±1.3)cm above the tip of external malleolus with diameter (0.6±0.2)mm;②.2~6 musculocutaneous perforators were given off by the artery of outer head of gastrocnemius muscle to supply nutrition to the sural nerve-small saphenous vein;③.intermuscular perforators from peroneal artery supplied blood to fibula and outer head of soleus muscle.the perforators with an average outer diameter of （1.3-1.6）cm gave off cutaneous branch ,fascial branch and nutritional vessels to the sural nerve-small saphenous vein,which formed the vessel chain of the sural nerve-small saphenous vein ,sub-fascial and suprafascial vessel net.

结果：1、解剖实验证实：①、腓肠神经-小隐静脉营养血管来自腓动脉肌间隔穿支4～8支，最远的跟外侧动脉穿支距外踝尖上(1.0±1.3)cm，外径(0.6±0.2)mm。②、腓肠肌外侧头动脉沿途发2-6支的肌皮穿支营养腓肠神经-小隐静脉。③、腓动脉肌间隔穿支营养腓骨、比目鱼肌外侧半。上述穿皮支平均外径在0.3～1.6mm，发出皮支、筋膜支、腓肠神经-小隐静脉营养血管，形成腓肠神经-小隐静脉血管链以及深、浅筋膜血管网。

The medicine groups (small dose and large dose group) were given the herb mentioned above 40 days. Take postcava blood to view the blood index and microanatomy of vessel wall.

造模成功后，给药组灌服药物40天，然后下腔静脉取血，测定各观察指标和主动脉血管壁组织学变化。

People often occur in elderly vascular sclerosis, high blood pressure sustained more easily lead to cerebral arteriosclerosis, vessel wall hyalinization appears fat, thus weakening the strength of the vessel wall, together with the blood of the structure of the wall is relatively weak, the middle vascular myocytes less, the lack of external elastic layer developed arterial adventitia easily occurred in the brain artery wall limitations small expansion, the formation of micro-miliary aneurysm.

人到老年血管常会发生硬化，持续的高血压更容易导致脑动脉硬化，血管壁出现脂肪玻璃样变，从而削弱血管壁的强度，加上脑血管壁的结构比较薄弱，血管中层肌细胞少，缺乏外弹力层，动脉外膜不发达，容易造成脑内小动脉壁发生局限性扩张，形成粟粒性微动脉瘤。

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。

A general conclusion,that(1)the blood flow is proportional to the cubic power of the vessel diameter;(2)the shear ratio of the vessel surface is independent of the vessel diameters.

导出了血流量与管径立方成正比的结论以及壁面切变率与管径无关的推论。

The reticulated vessel which has large cavity has thicker wall due to more elastic fibers and more smooth muscles and its endothelium is cuboidal epithelium which has rotundity karyons. But the reticulated vessel which has small cavity has thinner wall due to less elastic fibers and less smooth muscles and its endothelial cells are flat epithelial cells which have long-shuttle-shaped karyons. In some regions, the ducts are very small in diameter and thin of wall, and they become blood sinus in the end.

管腔大者，管壁厚，弹性纤维、平滑肌纤维多，内膜靠腔面内皮细胞多成立方状，细胞核端位近圆形；管腔小者，管壁薄，弹性纤维、平滑肌纤维少，内皮细胞扁平、排列稀疏，胞核长梭形；一些区域管径极小，管壁极薄，成为开放的血窦，只允许一个血细胞通过。

As is appropriate for many other disease concerns and health conditions, Frei said, a diet that's heavy in fruits and vegetables seems to slow down the loss of blood vessel function.

是适合许多其他疾病的关注和卫生条件，弗雷表示，饮食沉重的蔬菜和水果似乎放慢的损失血管功能。

According to Balz Frei, professor and director of the Linus Pauling Institute, and co-author on this study, a strength of this approach is that it points the way to use diet to prevent the decline in blood vessel function with age, and to treat it, if necessary, through drugs.

据鲍尔茨弗雷，主任，教授莱纳斯鲍林研究所和合著这项研究中，了这一方法的力量在于它点使用方式的饮食，以防止下降，血血管功能与年龄，并把它，如果必要的话，通过药物。

Appear for many times in the website " university of German hamburger ocean "," university of ocean of American E Hai Russia " the academic orgnaization that waits for fictitiousing zero; Be in another " total courtyard of ill research of blood-vessel of head of China International heart " in the website, one's words exaggerated publicizes video scroll to broadcast.

网站里多次出现&德国汉堡海洋大学&、&美国俄亥俄海洋大学&等子虚乌有的学术机构；在另一家&中国国际心脑血管病研究总院&网站里，言辞夸张的宣传视频滚动播放。

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。
