VEGF can facilitate endothelial proliferation strongly and vasotropic growth with conjugating vascular endothelial cells specific receptor.

在众多的血管生成因子中，VEGF是最有力的血管生成因子，它通过和血管内皮细胞的特异性受体结合，具有强大的促内皮增殖、促血管生成作用。

At 14 days after operation, VCAM-1 was still positive on the surface of uncovered endothelium, while more abundant expression was seen in the bottom of neointima near internal elastic lamina. Conclusions NF-κB activation and VCAM-1 expression participate in the inflammation of rat denudated artery.

核因子κB和血管细胞黏附分子1参与大鼠的主动脉损伤后的炎症过程；核因子κB的活化与失活成动态变化；血管细胞黏附分子1不同时间表达在不同的部位，核因子κB的活化与失活在血管细胞黏附分子1的表达与消退之前，核因子κB对血管细胞黏附分子1的表达起调节作用。

Results: The vascular endothelial cells were denudated, the spaces of contractile fiber cells increased and appeared puff, the vassular elastic fibers ruptured, flexed and deformed visibly. Some parts of the vessel wall ruptured completely or partly, leading to bleeding.

结果：股动脉血管内皮细胞剥脱；血管平滑肌细胞间隙增大呈疏松状；血管的弹力纤维有明显的断裂，屈曲变形；部分血管壁全层断裂或部分断裂，导致出血。

However, models of human innervated and non-innervated blood vessels have seldom been reported, and the regulating mechanism of non-innervated blood vessels is not clear yet.

故研究内皮细胞对血管的调控机制，应该区分所要研究的血管有无神经支配，而目前人体有、无神经支配的血管模型少见报道，有关无神经支配血管的调控机制的报道也为数不多。

ELF-EMF treatment not only increased the blood vessel formation of HUVECs, but also enhanced a functioning vascular network inosculating with recipient host circulation.

极低频电磁场处理不仅可以促进血管内皮细胞形成血管结构，而且形成的血管结构能够与宿主自身的血管结构相吻合。

Methods The free flap donor sites with long vascular pedicle and large diameter of vessel were routinely chosed, and chose receipt vessels with large diameter and proper position, and perform vessel ananstomosis under surgical loups instead of microscope.

方法选用血管蒂较长和血管口径较粗的游离组织瓣供区，选择口径粗大和位置合适的受区血管，将游离瓣制备成外露瓣，以利于术后血供的监测，在手术放大镜下行血管吻合，部分病例同时吻合2根静脉，以确保游离瓣的静脉回流。

The rationals of anti-angiogenesis are the following: the therapeutic target is tumor endothelial cells which are more genetically stable, more homogeneous, and with lower mutation rate; the anti-angiogenesis drugs can contact endothelial cells directly, with higher potency and lower drug barriers and side effects; the aim of anti-angiogenesis therapy is to block the oxygen and nutrition supply from vessels, instead of killing tumor r ells per se; the aim of anti-angiogenesis is to reduce tumor size instead of eradicate tumor which are different from traditional chemotherapy.

使用抗血管新生疗法根据的理论基础为以肿瘤血管的内皮细胞为治疗药物的攻击标的；肿瘤血管的内皮细胞基因比较稳定、同质性高、而且突变率低；投与的药物可以直接接触内皮细胞，减少投与药物屏障，因此增加有效投与药物的能力及减少药物副作用；以截断供应肿瘤氧气养分的血管为目标：以减小肿瘤的体积大小为目的，与传统化学疗法以根除肿瘤的目标不同。

Following successful modeling, rats of bFGF group were intratracheally injected with 400 U bFGF and rats of VEGF group with 2 μg VEGF, once a week for three times. MSCs group was injected 1 mL suspension of 4×109/L MSCs into tail vein. MSCs+VEGF group was injected MSCs into tail vein and intratracheally injected VEGF (2 ug, three times) at the same time. Model control and normal control groups were intratracheally injected with equal volume of sodium chloride.

成功造模后，碱性成纤维细胞生长因子组气管内注入400 U碱性成纤维细胞生长因子，血管内皮生长因子组气管内注入2 μg血管内皮生长因子，1次/周，共3次；单纯细胞移植组于尾静脉注入4×109 L-1骨髓间充质干细胞悬液1 mL；血管内皮生长因子+细胞移植组气管内注入血管内皮生长因子的同时，尾静脉注入骨髓间充质干细胞；模型对照组、正常对照组给予相同体积的生理盐水。

It is necessary to conduct surface modification of small-diameter vascular prosthesis and to enhance hemocompatibility.

因此有必要对小口径人工血管进行表面改性，增加血液相容性，主要改性方法有改变人工血管材料表面结构，增加人工血管表面内皮细胞黏附及人工血管材料表面的接技改性等。

The laboratory research and chinical trials to prove.courage lcecontains active material that it can quickly penetrate through body's cell.so to directly provides for the cell,fill the skin intercellular space the crevice which is senile withered because of the cell stays benind supply the active elements necessary for the body cells metabolism,to activate the function of endothelium cells of blood vessels,promote the blood vessels balance, compose and secrete various blood vessels active elements,contains abundantsulfuric cartilage element,sulfuric amido etc.,all of fatty acid in human body.and it can accelerete the re-generation of blood cells,add the quantity of the hemoglobin and red blood corpuscle so to improve the blood parameter,and fundamentally improve the body cells metabolism and nutrition supply for all the organs,as a result,you will thoroughly refresh yourself and bloom vitality of youth.

实验室研究和临床试验证明，LCE所含活性物质能够迅速穿透人体细胞，直接为细胞供养，填补肌肤细胞间因细胞衰老干瘪而留下的空隙全面补充人体细胞新陈代谢所必须的活性物质，激活血管内皮细胞功能，促进血管平衡，合成和分泌多种血管活性物质：富含的硫酸软骨素、硫酸氨基葡萄糖等能改善和调节人体脂代谢，有效清除体内血液中多余的脂质和脂蛋白清除在血管壁内膜沉积的脂类物质，保持人体脂肪酸均衡：能够加快血液细胞更新，提高血液中的血红蛋白和红血球数量，改善血液参量，从根本上改善人体细胞的新陈代谢，改善人体各组织器官的营养供给，使人由内而外脱胎换骨，重新焕发青春活力。

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。
