门静脉

Objective To explore the dynamic expression of TNF-α and VEGF in the development of esophageal varices in rats with portal hypertension.

目的 探讨TNF α及VEGF在门静脉高压食管静脉曲张大鼠食管局部的表达及意义。

There was no relationship between portal blood flow and size of esophageal varices.

此外，门静脉血流量与食道静脉曲张之程度并无关连性。

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 addition, the pathology form experiments of portal veins, and colons of rabbits and rats will be examined carefully for the applications of clinical trials.

另外，兔子和大鼠肝门静脉实验的病理资料会用来评估在临床试验上的应用。

Results: For aortic ghosting, the scores of c-TrueFISP and c+TrueFISP of two groups are lower than c+VIBE, p

此外，还对100例患者的肝内门静脉和肝静脉的解剖变异进行了统计分析。

P.01 . conclusion:(1) IgA of the lamina propria mucosae would lessoning while the endotoxin in portal veinwas heightening, and the lesson of the I L-6mRNA was the main reason of the lesson of IgA in the lamina propria mucosae, so, the impairment of barrier of the intestinal mucosa was caused by the impairement of the organic immunological function descent while there was obstructive jaundice existing.

(1) 肠粘膜固有层内IgA表达减少伴随门静脉血内毒素浓度的增加，而肠粘膜内IL-6mRNA表达的减少是导致肠粘膜固有层IgA表达减少的重要原因之一，因此可推论肠粘膜免疫屏障功能的受损与梗阻性黄疸时机体的免疫功能受抑有关。

The portal vein ligated rat is the experimental model most widely used to study this syndrome and it has been considered that a systemic inflammatory response is produced.

最常用的研究本症状的模型是结扎小鼠门静脉主干建立动物模型，并且它被认为有全身性炎症反应产生。

Methods: Porcine livers were harvested from common health dogs, performed by dual vessel perfusion and oxygenating blood together.

自普通健康的杂种犬获取供肝，采取同时灌流门静脉和肝动脉，共同氧合灌流液的方法对离体肝脏进行灌注试验。

Objective To evaluate the characteristic and diagnostic value of portal tumor thrombi on MRI and MR portography.

目的 评价门静脉癌栓MRI和磁共振门脉造影（MR portography，MRP）的特征及诊断价值。

In our study,to compare the therapeutic effect and significance of different treatment methods for primary liver cancer with portal vein tumor thrombi.

现对31 例原发性肝癌伴门静脉癌栓并具备随访资料患者的治疗进行回顾分析，以比较不同治疗方法的的疗效及其意义。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
