The vasomotion was induced by noradrenaline in vivo, then the changes of vasomotion after injecting SI and Na-monomethyl-L-arginine （L-NMMA, a NO synthase inhibitor） were measured respectively on a TV monitor using a TV camera mounted on the microscope, and the influence of L-NMMA on effect of SI was also observed.

Paired t-test was used to compare the intensity value.Results:After having injected FX530,enhancement of liver on grey scale imaging was divided into four continuous phases-arterial,phase,portal veinous phase,capillary phase and delayed vascular phase,three phases in kidney—arterial,capillary and delayed vascular phases,but no parenchyma enhancement appeared in testis.Parenchyma enhancement in liver showed"detained enhancement",while in kidney it showed "wash-in and wash-out".

结果：造影后，肝脏二维灰阶增强分为四个连续的时相即动脉相、门静脉相、毛细血管相和延迟血管相，实质增强有&滞留增强&现象；肾脏二维灰阶增强分为动脉相、毛细血管相和延迟血管相，肾实质增强表现为一过性；睾丸仅表现为血管增强，睾丸实质无增强。

In this study, human tongue cancer Tca8113 cells and human umbilical venular endothelial cell ECV304 are treated with CPT and the cell proliferation and apoptosis are detected in order to investigate the effect of CPT on Tca8113 and the mechanism of antiangiogenesis.

本研究以喜树碱作用于舌鳞癌细胞(Tca8113)及人脐静脉血管内皮细胞(ECV304)，检测细胞增殖及凋亡状况，以研究喜树碱对舌鳞癌细胞及血管内皮细胞的生长抑制和凋亡诱导作用，探讨喜树碱抗鳞癌的作用及可能机理，并初步探索其抗血管生成机制，为该药治疗皮肤肿瘤和银屑病奠定实验基础。

Aim: To investigate the effect of mifepristone on expression of Ang-1 in human villous trophoblasts during the early pregnancy and its role in regulating villous angiogenesis.

目的：通过观察米非司酮对人早孕绒毛滋养细胞血管生成素-1(Ang-1)表达及绒毛间质血管生成的影响，探讨Ang-1在绒毛间质血管生成的作用。

Results The endothelial cell and fibroblast of valves and vessel walls in experimental group were completely decellularized, no cell fragments were retained within the matrix scaffold; collagen fiber and elastin fiber had been preserved with intact structure and wavily arrayed; deoxyribonucleic acid content of valves and vessel walls in experimental group were decreased by 97.58%, 97.25% compared with that of control group.

结果 实验组瓣膜及血管壁中内皮细胞、成纤维细胞去除完全，无细胞核碎片；瓣膜及血管壁胶原纤维和弹力纤维呈波浪状排列、整齐，结构完整；瓣膜、血管壁的基因组脱氧核糖核酸含量分别较对照组下降97.58％和97.25％。

Methods Before the total correction of TOF was performed, the collateral arteries were transcatheter closured in 3 cases with huge aorta pulmonary collateral arteries (2 cases with PDA occluder, 1 case with coil).

术前介入治疗：3例有巨大体肺侧支的重症TOF在根治术前予以侧支血管堵塞术，其中2例采用国产动脉导管未闭封堵器堵闭体肺侧支血管，1例采用可控弹簧圈栓塞体肺侧支血管。

These drugs reduce blood pressure by blocking an enzyme that converts angiotensin to an active form that constricts blood vessels.

这些药物通过拦阻激活血管紧张肽的酶降低血压。血管紧张肽造成血管收缩。

Supplementation of folate in diets may reduce hyperhomocysteinemia induced by excess intake of methionine and decrease the expression of NF-κBP65 protein and monocyte chemoattractant protein-1 (MCP-1) in carotid common artery after balloon angioplasty, These data show that Hcy may exacerbate neointima hyperplasia after denuding injury by increasing the expression of inflammatory factors via the activation of NF-kB, Folate can reverse the effect of Hcy on the activation of NF-κB and the expression of MCP-1, an effect of preventing the restenosis postangioplasty.

而Hcy有可能通过激活核转录因子通路增加损伤血管组织炎症因子的表达而加重血管球能损伤后新内膜的过度增生过程，叶酸能对抗Hcy的上述作用，对高同型半胱氨酸血症引起的血管成形术后再狭窄可能有一定的预防作用。

Methods: Immunohistochemical analyses were performed on human tissue specimens from enucleated eyes (n = 14) to assess total vessels, neovessels, mature vessels, and cell proliferation.

用免疫组化法评估摘除的人体眼组织样本(n = 14)的总体血管、新生血管、成熟血管及细胞增殖情况。

Results 甀ntrahepatic vascular diseases, liver tissues diseases and the expressions of VEGF were different in different time of experiment induced by CC14. In earlier periods (2 to Swk) of rats? liver tissues induced by CC14, the inflammatory was significant. Fatting degeneration was seen in hepatocytes around central veins and part of small vesells.

早、中期（2～5wk），肝组织炎症反应显著，中央静脉及部分小血管周围肝细胞脂肪变，VEGF阳性肝细胞主要分布在脂肪变区域；晚期（8～12wk）则肝组织炎症反应轻微，但肝细胞病变显著，血管破坏、血管及成肌纤维细胞增生更趋明显，并见有局部纤维瘢痕形成，假小叶内肝组织肝窦扩张或毛细血管化，其VEGF示阳性。

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。
