Levels of expression significantly increased after day 4 posttransplantation and persisted through the whole course of rejection, but levels of expression were obviously lower in the peripherial blood than those in portal vein blood. In contrast, the control group showed no expression of mRNA for perforin and granzyme B in portal vein and peripherial blood.

结果 急性排斥肝移植组术后3天门静脉和外周血中均有穿孔素和颗粒酶B基因mRNA表达，4天后表达明显增强，并贯穿整个排斥反应的全过程，但外周血表达的强度明显较门静脉血为弱，同基因对照组术后14天内无穿孔素和颗粒酶B基因表达。

Results The rejection group began to show the mRNA of perforin and granzyme B up-regulation on day 3 posttransplantation, when no histologic evidence of rejection was found. Levels of expression significantly increased after day 4 posttransplantation and persisted through the whole course of rejection, but levels of expression were obviously lower in the peripherial blood than those in portal vein blood. In contrast, the control group showed no expression of mRNA for perforin and granzyme B in portal vein and peripherial blood.

The vein grafts with perivenous support by fibrin glue demonstrated a statistically decrease in neointimal and medial hyperplasia compared with non-supported vein grafts（p.01）. immunohistochemical analysis showed that the expression of proliferating cell nuclear antigen was inhibited significantly in fs group compared with ns group. almost intact endothelium was showed in fs grafts（p.01）. but in ns grafts there were severe endothelium damages where lymphocytes infiltrated. in ns grafts, the smooth muscle cells were hyperplasia and migrated to intimal, whereas in fs group, the hyperplasia of smooth muscle cells were inhibited and migrated to adventitia.

免疫组化结果显示与ns组相比，fs组移植静脉细胞增殖核抗原表达明显受到抑制；ns组内皮层损伤严重，有淋巴细胞侵润，而fs组内皮层则几乎完好无损（p.01）；在ns组平滑肌细胞增殖活跃且向内膜迁移，fs组平滑肌细胞增殖受到抑制，且向外膜迁移；在fs组移植静脉外膜有丰富的成熟微小血管网形成，但是在ns组，微小血管数量则非常少。

This operation is suitable for the following portal hypertension: simple occlusion of hepatic vein (a pathological type of Budd-Chiari syndrome)thrombosis in portal vein or prehepatic portal hypertension due to cavernous transformation; intrahepatic portal hypertension with rebleeding after treatment of splenectomy or without operation, and the patients with liver function in Child A or B class.

本手术主要适应于以下原因引起的门静脉高压：①单纯化肝静脉闭塞(布-加综合征的一种病理类型)；②门静脉主干血栓形成成海绵样变性引起的肝前性门静脉高压；③肝内型门静脉高压行断流术后再发出血或未行手术，肝功能为Child A和B级者。

What's more, after several the stitch of the bionics vein , MicroHand as the primatal surgery succeed stiching the vein in the rat's cervix.

最后，经过对仿造血管的多次吻合操作后，MicroHand系统作为主刀医生成功的对兔子颈部动脉进行了血管吻合手术。

Methods Fifteen cadaveric heads were taken in this study. The arteries and veins of the heads were perfused with red and blue latex, respectively, for simulating pterion approach under microscope. The spatial relationship between the anterior segment of basal vein and the operation space was examined. The cranium was then removed, the basal vein and its branches were observed and measured in the free brain.

取15具（30侧）尸头标本，动、静脉分别用红、蓝色乳胶灌注，在显微镜下模拟翼点手术入路，分别从手术中常用的间隙进行操作，观察基底静脉前段与手术间隙的关系。

Firstly, the high resolution pictures of dragonfly wings from sample tests were studied thoroughly, and the unique feature of the reticulate vein distribution and the variation of the vein sizes and the grid shapes in different zones were figured out;then several computational models based on a dragonfly wing were established by using ANSYS, and beam 189 and shell 93 elements were used respectively in modeling of the veins and the membrane so as to ensure the compatibility between the veins and the membrane at a deformed state;these models subject to uniform loading cases were analyzed respectively so as to explore the unique performances of the wing structure, furthermore, through eigenvalue spectrum analyses of these models, the special role of the pterostigma in eliminating or suppressing the wing quivering effect was also evaluated.

首先，对实验中获取的高清晰度的蜻蜓翅膀数码图片进行了细致地分析，找出了翅膀网状翅脉结构中翅脉的分布规律与尺寸变化、网格形状的差异及不同形状网格的分布等独特的结构特征；再利用ANSYS建立蜻蜒翅膀网状翅脉结构模型，采用三节点等参数梁元beam189模拟翅脉和八节点等参数曲壳单元shell93模拟翅膜，以满足翅脉和翅膜间的变形协调性要求；通过非线性数值分析，探索了蜻蜓翅膀网状翅脉结构在均布荷载作用下所具有的独特的结构性能；通过模态分析，揭示了翅膀前缘靠近翼尖附近的翅痣在翅膀消震减振中所发挥的作用。
