But the intimal hyperplasia has been one of the major cause of the graft late failure, especially for the middle and small artery.

然而，术后的血管内膜增生已成为中、小血管手术后期失败的一个主要原因。

Objective To study the relationship between intrahepatic vascular diseases, endothelial growth factor and hepatitis B.

目的 研究肝内血管病变及血管内皮生长因子与乙型肝炎的关系。

Moreover, because the decompounding to the basement membrane and intramatrical is extremely important to the move of endothelium cell which is essential to the blood vessel forming.

另外，因为对基底膜和基质组织的降解对血管生成所必需的内皮细胞迁移极为重要，所以，认为MMPs是肿瘤血管生成的关键之一。

PartⅢExperimental study of autologous BM-MNCs by intramyocardial transplantation into ischemic myocardium of AMI in swines Objective: To evaluate the effectiveness and safety of BM-MNCs by intramyocardial transplantation. Methods: 11 swines were divided into two groups: BM-MNCs group (n=6) and control group (n=5), total 2×10~8 cells.

实验动物分为心肌内移植MNCs组(n=6)及心肌内盐水对照组(n=5)，心肌内移植细胞数2×10~8；移植后4周观察移植细胞归巢情况、小血管密度、心功能及冠脉侧枝血管形成情况及可能发生的副作用。

By univariate analysis, deep-seated AVMs, small AVMs, deep venous drainage , a single draining vein and intranidal aneurysm were associated with hemorrhagic presentation. There was no statistically significant relationship between gender, age, type of arterial feeders, type of nidus, stenosis of draining vein and AVM hemorrhage.

单因素分析表明，深部脑AVM、小型脑AVM、深静脉引流、单一静脉引流和畸形血管团内动脉瘤与脑AVM出血相关，性别、年龄、动脉血供类型、畸形血管团类型和引流静脉狭窄与脑AVM出血无相关性。

Results: The mechanisms of tumor angiogenesis included sprouting angingenesis, intussusceptive angiogenesis, coopted vasculature, recruitment of endothelial progenitor cell, mosaic blood vessel and vasculogenic mimicry.

结果：肿瘤血管生成的机制目前发现的有5类：芽生式、套叠式、充塞式、内皮祖细胞的参与、马赛克式及血管生成拟态。

Methods\ ELISA (enzyme\|linked immunosorbent assay) was used to determine serum VEGF concentration of 15 patients with proliferative hemangioma, 6 with involuted hemangioma, 6 with vascular malformation and 8 infants of the control group.

用免疫酶标技术分别检测 15例增生期血管瘤、6例消退期血管瘤、6例血管畸形及 8例对照组婴儿血清中血管内皮细胞生长因子的浓度。

The complexity and vastness of the layout of about 5 kilometers of blood vessels in the head and face assures that each person's vascular arrangement is irreproducible and hence unique.

人们头部和脸部大约5公里长的血管所具有的复杂性保证了每个人的血管分布是不可再现的，因此也就是独一无二的。

Objective To analyse the vasodilative mechanism of isocorydine, its effects on the increasing of the cytosolic free Ca 2+ level ([Ca 2+ ]i) induced by noradrenaline and high potassium in the blood vessel smooth muscle cells were investigated.

目的 观察扩血管药异紫堇啡碱对去甲肾上腺素和高钾所致血管平滑肌细胞内游离钙浓度([Ca2 + ]i)增高的影响，分析该药扩血管作用的原理。

All the four factors are involved in the angiogenesis of laryngopharyngeal malignant melanoma.

结论VEGF、bFGF、TGFβ1和TAF是咽喉部恶性黑色素瘤中血管生成的重要因子，并通过促进血管生成影响病人的预后。

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。
