血管形成的

Aims: to assess prospectively the extent of, and predictive factors for recanalization of acute non-cirrhotic, non-malignant PVT. Between 2003 and 2006, patients were prospectively enrolled in 9 European countries, if there was radiographic evidence for a recent thrombus in the portal vein trunk or one of its main branches, and absence of cavernoma.

目的：前瞻性的估计急性非硬化非恶性门静脉血栓形成的程度和血管再通的预测因子。2003-2006年期间，前瞻性的纳入9个欧洲国家的患者，要求其在门静脉主干或一个主要分支有新近血栓的X射线证据并且无海绵状血管瘤。

As it known, mistakes in spatiotemporal expression of critical genes result in congenital cardiovascular diseases. Furthermore, studies on high risk population of cardiovascular disease have also suggested the relationship between noncongenital cardiovascular diseases and genetic factors.

在心血管系统疾病的研究中已发现，有些是由于某些基因在时空上的表达紊乱所引起，而对部分心血管系统病症高发人群的研究也证明部分后天形成的心脏病与遗传因素有关。

在心血管系统疾病的研究中已发现，某些基因在时空上的表达紊乱可导致先天性心脏病，而对部分心血管系统病症高发人群的研究也证明部分后天形成的心脏病与遗传因素有关。

Down-regulated expression of PTEN and up-regulated expression of VEGF〓 were considered as two important events in tumorigenesis of ovarian cancer and could act as molecular markers to indicate the pathobiological behaviors of ovarian cancer. Decreased PTEN expression and increased VEGF〓 expression were closely associated with tumorigenesis and pathobiological behaviors of ovarian endometrioid and serous cancer respectively. Reduced expression of PTEN gene might be involved in carcinogenesis and progression of ovarian cancer by up-regulating the VEGF〓 expression to enhance angiogenesis.

在卵巢癌组织中PTEN基因mRNA表达下调和VEGF〓基因mRNA表达上调是卵巢癌发生的重要分子事件，可作为反映卵巢癌病理生物学行为的指标，且分别与卵巢内膜样癌和浆液性囊腺癌的发生和病理生物学行为关系密切；PTEN基因mRNA表达降低可能通过上调VEGF〓基因mRNA表达促进新生血管形成，进而参与卵巢癌的发生和侵袭。

Methods One hundred patients (80 males and 20 females, aged from 11 to 75 years) who suffered from cerebrovascular disease received routine cerebral CT examination in resting state firstly. After breathing in the xenon-oxygen mixed gase in proportion, they once more received the cerebral CT examination. Nine of them were injected vasodilating agent, then received the enhanced CT examination again. Finally, these results were transferred to the Xe-CT CBF analysis system to analyze the CBF quantitatively.

选择100例脑血管病患者（男80例，女20例，年龄11～75岁）在安静状态下进行CT头颅常规扫描然后吸入氙气与氧气按一定的比例形成的混合气体后再次进行扫描，其中9例注入血管扩张药后进而行增强扫描，最后将扫描结果上传Xe-CT CBF分析系统，进行CBF的定量分析。

Human brain bridging veins may be the key point of brain vein blood outflow volume because of existing of "outflow cuff segment": ICP increased, outflow resistance increased, outflow volume reduced, then caused the aggravatation of vein blood deposition in vein bed. Such a sequent procedure formed an infernal circle: ICP increase-vein outflow reduce-vein blood deposition-ICP increase all the better.

该部分研究结果发现，由于流出口狭部的存在，人脑桥静脉是脑静脉血液流出被动调节机制的关键环节，颅内压增高，流出阻力增加，流出量减少，进而又加重了血液在静脉血管床的淤积，形成颅内压增高-静脉流出量减少-静脉血淤积-颅内压进一步增高的恶性循环。

Background— The high mechanical index impulses from a diagnostic ultrasound transducer may be a method of recanalizing acutely thrombosed vessels if the impulses are applied only when microbubbles are channeling through the thrombus.

背景—从超声诊断传感器传出的高的机械指数脉冲可能是再穿通急性血栓形成的血管的一种方法，假如这种脉冲应用仅当微气泡是多路传导通过血栓。

EVA coated Paclitaxel-eluting stent can inhibite the neointimal hyperplasia in stented areas of coronary arteries one month after stent implantation in mini-swine model, which shows markeding promising of this product manufactured in Chinese factory. But the stent can also delay the reendothelialization of the intima and have the potential risk of late thrombosis as observed in studies of TAXUS stent, which suggests the importance of antipletelet therapy in clinical practice.

用该多聚物涂层制成的紫杉醇药物洗脱支架明显减少带药量的情况下可抑制1个月时猪冠状动脉新生内膜增生，均有开发、生产的前景，但和TAXUS紫杉醇洗脱支架一样可造成血管再内皮化及内膜修复延迟，且有造成晚期血栓形成的风险，提示临床应用中应加强抗血小板治疗。

However, there were no significant differences between groups in the eight-month thrombosis rates, in rates of aneurysm formation or total occlusions.

但是在实验治疗后的8个月中，两组在形成血栓，血管瘤和血管阻塞的速度没有显著的差别。

Cellular growth, constrictions function and free Ca2+ in cultured pulmonary artery smooth muscle cells were measured by the methods of MCT, morphometry and calcium fluorescent probe Fura 2-Am.

肺动脉和体动脉不同，对5-HT的缩血管效应比对去甲肾上腺素的更敏感。对5-HT在不同原因形成的肺动脉高压中的作用要做具体分析。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
