结论：门静脉高压症大鼠存在高动力循环状态(HCS)。
CONCLUSION: The portal hypertensive rats are in hyperdynamic circulatory state (HCS).
而高动力循环状态是门静脉高压的重要维持因素，其形成与一氧化氮(NO)的作用密不可分。
The maintenance of portal hypertension in hyperkinetic circulatory state is closely related to nitric oxide (NO) formation.
目的研究门静脉高压症病人肝组织内血管及肝窦壁内皮细胞的凋亡及其对肝微循环的影响。
Objective To investigate the intrahepatic vascular and hepatic sinusoidal endothelial cell (SEC) apoptosis and its influence on hepatic microcirculation in patients with portal hypertension.
肝循环门静脉系统的疾病往往伴随着血流动力学的异常。
Diseases of Hepatic-Portal vascular system are often accompanied with hemodynamic abnormalities.
目的：评价多层螺旋CT门静脉成像(MDCTP)在门脉高压侧支循环血管显示中的价值。
Objective: to evaluate the value of multi-detector row spiral ct portography (MDCTP) in demonstrating portal system and its collaterals in portal hypertension.
结论：慢性重型肝炎容易形成门静脉高压，门静脉血流灌注量明显减少，造成肝脏微循环障碍。
Conclusion: Chronic hepatitis gravis is apt to form acute portal hypertension with decreased perfusion of portal vein system thus causing liver in a state of lacking of blood and oxygen.
结论：实时间超音波对傍门静脉血管的侦测及鑑别傍门静脉侧枝循环与肝动脉，是有用且可信赖的工具。
