Objective: To assess the feasibility and outcome of orthotopic liver transplantation (OLT) with no veno-venous bypass(v-v
bypass) in adult patients. Methods: Between 1999 and 2001, 43 adult patients underwent OLT with v-v bypass, 33 with no v-v
bypass. The operation time, anhepatic time, amount of blood loss, amount of blood transfusion, ICU stay days of the two groups
were compared; renal function and gastrointestinal function in the two groups were examined. Results: There was no significant
difference in mean serum creatinine on day 3 and gas discharge time in patients with v-v bypass or not. With no v-v bypass,
the average operation time was 5.7±1.3 hours, anhepatic time was 64±13 minutes, median amount of blood loss in operation was
4000±820 mL, median amount of blood transfused intraoperatively was 4650±910 mL, median ICU stay was 5.7 days; all those were
lower or shorter than those with v-v bypass; and these differences between the two groups had statistical significances. Conclusion:
OLT with no v-v bypass is safe and can be performed in the majority of adult patients. The practice of liver transplantation
with no v-v bypass is associated with shorter total operation time, shorter anhepatic time, lower blood product usage, and
shorter ICU stay compared with standard technique of OLT with routine use of v-v bypass.

INTRODUCTION 1,25-dihydroxyvitamin D3[1,25(OH)2D3], the biologically active metabolite of vitamin D3, is a secosteroid hormone that not only regulates bone and calcium/phosphate metabolism but also regu-lates a number of other biological activities, in-cluding modulation of the immune response via specific receptors expressed in antigen presenting cells (APC) and activated T cells. Recently, in-creasing evidence showed that the modulatory role of 1,25(OH)2D3 on T cell phenotype and … 相似文献

Objective: To investigate the in-vitro antitumor immune responses of dendritoma formed by mouse hepatocellular carcinoma (HCC) cells and lymphotactin (Lptn) gene modified dendritic cells (DCs). Method: DCs prepared from mouse bone marrow were genetically modified by lymphotactin adenovirus, and fused with H22 cells by polyethylene glycol (PEG). RT-PCR and ELISA were employed to identify lymphotactin expression at mRNA and protein level. Cell phenotypes and fusion efficiency was detected by FACS. The stimulatory effect of DC on T cells was detected by mixed lymphocyte reaction. The cytotoxicity activity against H22 cells was assayed by LDH method. Results: Lymphotactin could be efficiently expressed by DCLptn/H22 hybridoma. DCLptn/H22 cells could induce potent T cell proliferation effect and generate strong cytotoxic T lymphocyte (CTL) reaction against allogenic H22 cells. Conclusion: Lymphotactin genetic modification could enhance the in vitro immune activity of the dendritoma. 相似文献

大鼠帕金森氏病动物模型的建立 总被引：2，自引：0，他引：2
采用SD大鼠30只，25只为试验组，5只为对照组。在三维立体定向仪上用微量注射器将6－OHDA32μg分两点注射入右侧纹状体，每周检测动物的旋转行为，第1周动物没有出现旋转行为，第2周动物出现明显的旋转行为，随后缓慢上升；至术后5周才升至较高的水平并保持平稳。其中有15只动物达到或超过了7r/min这一通常采用的标准，模型成功率达60％。酪氨酸羟化酶免疫组化显示：术后第1周至第5周右侧黑质TH免疫反应细胞逐渐砬少，各个时期的右侧黑质TH免疫反应细胞较对侧明显减少。采用此方法建立的大鼠帕金森氏病模型更加符合临床PD病人的病程进展并明显提高成功率。 相似文献

Use and effects of liver specific antigen in orthotopic liver transplantations were researched in this study. Group I: syngeneic
control (Wistar-to-Wistar); Group II: acute rejection (SD-to-Wistar); Group III: Thymic inoculation of SD rat LSA day 7 before
transplantation. The observation of common situation and survival time, rejection grades, NF-κB activity of splenocytes and
IL-2mRNA expression of grafted liver were used to analyze acute rejection severity and immune state of animals in different
groups. The common situation of group I was very well after transplantation and no signs of rejection were found. Recipients
of group II lost body weight progressively All dead within day 9 to day 13 posttransplantation; median survival time was 10.7
±0.51 days. It was an optimal acute rejection control. As for group III, 5 out of 6 recipients survived for a long time and
common situation was remarkably better than that of group II. Its rejection grades were significantly lower than that of group
II(P<0.05). NF-κB activity was only detected in group I at day 5 and day 7 after transplantation, whereas high activity of NF-κB
was detected at all time points in groupII and the low NF-κB activity detected in group III was significantly lower than that
of group II (P<0.05). No IL-2mRNA expression was detected at any time point in group I, whereas high level expression was detected at all
time points in group II and the low level expression only detected at day 3 in group III was significantly lower than that
of group II (P<0.05). Conclusion: LSA is an important transplantation antigen which is involved directly in the immunorejection of liver
transplantation. We report here for the first time that intrathymic inoculation of LSA can alleviate the rejection of liver
allotransplantation; and that grafts can survive for a long time thereby, thus leading to a novel way to achieve liver transplantation
immunotolerance.
