Objective To determine the content change of vascular endothelial growth factor and basic fibroblast growth factor in the wound fluid and their effect on angiogenesis in the wound healing during healing of maxillofacial soft tissue blast injury. Methods The improved rabbit model of maxillofacial blast injury was made by KTY-04 blasting cap.

摘 要：目的探讨颌面部软组织爆炸伤愈合过程中血管内皮细胞生长因子和碱性成纤维细胞生长因子在伤口液中含量的动态变化及其对创伤愈合中血管再生过程的刺激作用。

It is concluded that the initial ancotomic site of blood island genesis may be is mesoblast of extraembryonic blastoderm rather than the yolk sac; the blood vessel endothelium cells and the blood cells are generated parallel; the PGCs are the common ancestry of angioblast and HSC.

血岛最早发生的解剖位置可能不是卵黄囊而是胚外胚盘中胚层，血管内皮细胞与血细胞平行发生，PGC是成血管－造血干细胞的共同祖先。

The ideal bleb, he said, is a bleb that is diffuse and hypervascular but not avascular.

他说理想的滤泡有渗透性，多血管而非无血管。

They also did ultrasound and other tests to measure blood vessel function and the thickness of the artery wall.

他们还进行了超声波和其他测试，衡量血管的作用和动脉血管的厚度。

Compare the expression of VEGF and the newborn blood vessel area between the groups.

比较各组之间的血管内皮生长因子含量的表达及新生血管面积。

OBJECTIVE: To study the effects of prolonged 75% oxygen exposure on the expression of vascular endothelial growth factor and its receptors (VEGFR1 and VEGFR2) in the neonatal rat lungs and to elucidate the effects of prolonged exposure of high concentration of oxygen on lung vascular development and its relationship with bronchopulmonary dysplasia.

目的：研究持续吸入75%氧对新生大鼠肺血管内皮生长因子（vascular endothelial growth factor，VEGF）及其受体（VEGFR1和VEGFR2）表达的影响，探讨较高浓度吸氧对肺血管发育的影响及与支气管肺发育不良（bronchopulmonary dysplasia，BPD）的关系。

Abdominal bruit was heard in the right epigastric area. Renovascular hypertension was highly suspected.

同时在病患的右上腹部可以听到血管嘈音，高度怀疑是肾血管高血压。

METHODS: Autologous whole blood was injected into the vitreous cavity of albino rabbits after canalization, thus induced experimental PVR model. Concentration of PDGF.

采用眼穿通伤+注血法制备PVR模型，进行眼底及常规组织病理学观察，ELISA法检测玻璃体中血小板源性生长因子的浓度，用免疫组织化学方法观察增生膜与血管内皮细胞表面血管细胞粘附分子-1（VCAM-1）及细胞间粘附分子-1（ICAM-1）的表达。

Results The CaCl2 hollow stent could not only support the cannel of vascular, but also generate two membrane in the two side of anastomosis site. Thus the thickness of sealant was increased. It was effective to prevent leaking of cyanoacrylate glue and its toxicity.

结果：CaCl2中空支架不仅在血管吻合中支持血管，而且可以双面成膜，增加密封厚度，加强密封效果，能够有效阻隔医用胶对吻合口和管壁的毒性作用。

The new structure compounds (4, 54, 56) possessing vasodilatation were found. These compounds may be as lead compounds of developing antihypertension drugs. The synthesis method of peptidemimetics containing β-tetrahydro -carbolic acid was established for the first time.

在对上述化合物NO清除能力评价实验中，发现了一类具有舒血管活性新化合物（化合物4，54，56），这一类具有舒血管活性化合物的发现可以为研制高血压治疗药物提供先导化合物。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.
