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.

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.

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.
