Results The AVM animal model was successfully created in seven CEMPs, which was similar to human brain AVM in angio-architecture, angiographic-image, embolizing behavior and post embolization pathological findings. Thromboses were found inside the CJA vessels in 4 animals and in the rest 3 the CJA vessels were shrunk without thrombus.

结果在7只CEMPs中成功制作了AVM动物模型，该模型在血管结构、造影影像、栓塞表现和栓塞后病理改变上与人脑AVM的相似。4只动物颈动静脉吻合口血管腔内有血栓形成，其余3只吻合口血管塌陷皱缩，腔内无血栓。

At 24 h, Ang1 was expressed mainly in the lens, optic cup, mesencephalon, ventral part of hindbrain, and myotomes in the somites, while zfTie2 was mainly expressed in intersomitic vessels including dorsal aorta and axial veins, and sprouting vessels from the dorsal aorta in the trunk.

采用多聚酶链式反应，扩增了长约280bp的斑马鱼血管发生素1 cDNA部分序列，作为探针，以原位杂交法测定了血管内皮细胞生长因子和血管发生素1及其相应受体flk1和Tie2的表达。

During the guide wire operation, the following cares should be taken:(1) The head of guide wire needs to be bent to a certain degree and the degree of bend depends on the track of the lesion and diameter and characteristics of the vessel;(2) Insert the guide wire gently through the opening of coronary artery and ensure to deliver the guide wire into the vessel without any resistance;(3) Rotate the guide wire while delivering it across the stenosis lesion;(4) Once the guide wire is delivered to the place, no further operation should be performed before it is confirmed by angiography that the wire is in the true lumen of the vessel.

在引导钢丝的操作中应注意以下几点：(1)引导钢丝头部需弯成一定的弯度，弯度的大小应根据病变的走行、血管直径和特点来决定；(2)引导钢丝进入冠状动脉开口时，动作要轻柔，在确保推送引导钢丝无任何阻力情况下将其送入血管内；(3)引导钢丝通过狭窄病变时要边转动钢丝边推送；(4)引导钢丝到位后要造影确认其在血管真腔内，再行操作。

This, in turn, trapped in cold water for physical contact when the skin vasoconstriction, blood pressure increased slightly, only a very short time; soon surface on the re-expansion of blood vessels, a large number of vascular blood flow to the skin, the blood pressure at this time, it has not been exposed to cold water than also slightly more.

这又困为身体接触冷水时表皮血管收缩，血压略微升高，只是很短暂的时间；很快表皮的血管就再度扩张，大量血液流向皮肤的血管，这时的血压，就反而比未接触冷水时还稍低些。

Results:Compared with the normal controls, manifestations of severe right heart failure,well-elevated pulmonary arterial pressure and serious right heart hypertrophywere observed in the pulmonary hypertensive rats 28 days after left lungresection and MCT injection.

结果：与对照组相比，MCT 注射后28 天大鼠出现重度右心衰竭征象，平均肺动脉压、右室肥厚度均明显升高；镜下可见明显肺血管重构，表现为右肺纤维化、肺小动脉内皮和中膜平滑肌层增生、血管密度降低；肺组织中HGF、eNOS 表达明显减少、TGF-β和ET-1 显著升高(P0.05)，这些细胞因子表达量的改变与肺血管重构存在着明显的相关性。

Researches show that the disorder of the balance between the promotion factor and the inhibition factor of neovascularization is an important mechanism of the neovascularization. Suppressing the new blood vessel proliferation have already become the new target spot to treat this kind of disease.

研究发现新生血管形成因子与抑制因子之间的平衡失调是新生血管形成的重要机制，抑制血管增生已经成为治疗这类疾病的新靶点。

Scholars have made many scientific researches to improve the properties of graft wall and the techniques of antithronibogenicity in the past years, yet the long term patency of prosthetic grafts especially small-caliber ones with the diameter less than 5 mm has not been satisfactory due to proliferative stenosis.

过去已就提高人工血管的管壁性能和抗凝技术做了大量的研究，但是由于再狭窄导致人工血管，特别是口径小于5mm的人工血管长期通畅性问题依然没有满意的结果。

According to the authors, RLS might increase cardiovascular risk through a number of potential mechanisms. Among them is the possibility that the periodic leg movements of sleep, a hallmark of RLS, result in significant elevations in blood pressure and heart rate.

冠状动脉血管疾病以自我通报由医师诊断的心绞痛、心肌梗塞、或是冠状动脉血管重建术定义；心脏血管疾病以CAD或是有医师诊断的中风或心脏衰竭定义。

Or, how does VEC influence these characters and functions of its neighboring TC. These are all unclear. On the other hand, How does TC adhere to and destruct the vascular endothelium to enter and come out of the vascular cavity during the tumor haematogenous metastasis?

反之，位于TC邻近的VEC对TC的生物学特性、功能又如何影响以促进肿瘤血管系统的建立，尚不清楚；另一方面，在肿瘤的血行转移中TC如何粘附、破坏血管内皮以进出血管腔？

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。
