The polypeptide insulin or secretory granule released into pancreatic tissue fluid be rather easy entering into lymphatic duct of pancreas than into blood of hepatic portal vein. 注射或释放入胰腺组织液中的胰岛素等多肽激素或分泌颗粒,正常转运途径或规律,可能是通过淋巴管道,而非通常认为的肝门静脉途径转运入血发挥作用。
Results: Three hepatic fissure sites were localized with the help of 3 hepatic veins, the intersegmental fissure was localized with the help of left branch and right branch of hepatic portal vein. 结果:3条肝静脉的位置可精确定位3条肝裂。门静脉左、右支可精确定位1条段间裂。
The morphological observation of embranchment of the hepatic portal vein within liver 肝门静脉肝内分支的形态观测及临床意义
In group ③, the plasma TNF-α levels in jugular, hepatic and portal vein rose to significant peaks at 1 h simultaneously. 在组③肝静脉、门静脉和颈静脉血中TNF-α在1h同步迅速达到峰值。
All patients were treated for six months and investigated the changes of liver function, HBV-M, HBV DNA and the diameter of hepatic portal vein, spleen vein and spleen width. 治疗期间观察肝功能指标、HBV血清学标志、HBVDNA的变化情况,及B型超声波观察肝脏门静脉、脾静脉内径及脾脏厚度的改变。
In recent years some diabetes 'patients received islet cell transplantation through hepatic portal vein. 近年来,经门脉胰岛细胞移植技术在临床上已有开展。
There are many branching types in the right anterior and right posterior branches of hepatic portal vein; 肝门静脉右前支和右后支有多种分支类型;
Then the hepatic portal vein was clamped twice and sample samples were collected from the inferior hepatic vain to determine values of ET-1, TNF-α and IL-6. Liver tissue samples from the left lobe were stained with HE and observed under light microscope. 两次肝门阻断后于下腔静脉取血,检测血清ET1、TNFα、IL6值,同时取肝左叶肝脏组织病理检查。
Conclusion The mechanical properties of hepatic portal vein of pig change with aging, the pig matched the mechanical property of hepatic portal vein of human should be chosen for liver xenotransplantation. 结论猪肝门静脉的力学特性随增龄发生变化,在实施猪→人异种肝移植时应选择与人肝门静脉力学特性相匹配的月龄猪作为供体。
The volume index of spleen and inner diameter of hepatic portal vein were measured by ultrasonography. B超测定脾脏体积指数和肝门脉内径。
The arrange of common biliary ducts ( CBD)、 hepatic artery ( HA)、 hepatic portal vein ( PV): 73.97% of them HA is between CBD and PV, out of it is 26.03%. 肝门区胆总管(CBD)、肝动脉(HA)、门静脉(PV)排列关系:HA在CBD与PV之间者占73.97%,HA在CBD与PV之外者占26.03%。
A modified Roux en Y anastomosis was developed, which can prevent injury of hepatic portal vein during operation, and cul de sac syndrome after operation. 提出改良胆肠Roux-en-Y吻合术,它有防止术中门静脉损伤及术后出现盲端综合征的明显优点。
The changes of hepatic portal vein blood flow and oxygen metabolism during normothermic or hypothermic cardiopulmonary bypass 常温和低温心肺转流期间门静脉血流量及氧代谢的变化
Experimental Study of Hepatic Arterial Buffer Response after Occluding Hepatic Portal Vein and Superior Mesentery Artery Subsequently 分别缩窄肝门静脉及肠系膜上动脉后肝动脉缓冲效应的实验研究
There are two hepatic portal veins lying in the vein system. The caudal vein divide into three branches, among which the middle one forms the left hepatic portal vein while the other two form the kidney portal vein. 静脉系统中有两条肝门静脉,尾静脉分为3支,左右两支形成肾门静脉,中间一分支形成左肝门静脉。
Because of the complex physiological figure of the internal organization of liver and hepatic portal vein, three-dimensional modeling of hepatic portal vein using CT images is difficult. 由于肝脏内部组织和肝脏门静脉的复杂生理形态,使得利用肝脏门静脉血管的CT图像进行三维建模较难实现,目前该方面的研究尚处在初步阶段。
During the course of extraction of the vessel, we use anisotropic filter to pretreatment the image at first, then use multi-scale tube enhancement filter to enhance the vascular, and use region growing method to segment hepatic portal vein at last. 在肝脏门静脉的提取中,本文首先采用了各向异性滤波进行预处理,并利用多尺度的管状结构增强滤波器进行了血管增强,最后区域增长分割出肝脏门静脉。
At last, the paper designs and implements 3D Hepatic Portal Vein Modeling software based on the work above. 最后本文在以上工作基础上设计和实现肝脏门静脉三维建模软件。
The right hepatic portal vein, which divides into right anterior and right posterior branch, is wider and shorter than that of the left hepatic portal vein. 门静脉右支较粗短,分为右前支和右后支。
