【摘要】目的探讨慢性胰腺炎的诊治方法。方法对1997年5月至2002年11月期间所收治并经临床或病理证实的114例慢性胰腺炎患者的资料进行回顾性分析。结果主要临床表现为腹痛、体重下降、腹胀和消化不良。影像学特征为胰腺肿块、假性囊肿、胰管扩张和胰管结石。本组中有60例行外科手术治疗，术后发生并发症4例，死亡1例，其余54例经保守治疗症状缓解。结论慢性胰腺炎临床表现和影像学表现变化多样，应根据病变特点选择手术方式。
【Abstract】Objective To review the recent advances in the use of marginal liver in liver transplantation. Methods The literatures of recent years on the use of marginal liver for liver transplantation were reviewed and summarized.Results The donors with older age, hemodynamic instability, long stay in the intensive care unit and fatty liver are significantly clinical marginal liver donors.Conclusion Though the use of marginal liver donors negatively influences the results of liver transplantation, marginal liver expands the liver source for liver transplantation with a good result.
【Abstract】Objective To review the advances in overcoming multidrug resistance of tumors caused by mdr1 gene.Methods Different ways of overcoming multidrug resistance of tumors caused by mdr1 gene in the literatures were reviewed. Results One of the important reasons causing multidrug resistance was due to the overexpression of mdr1 gene and its product Pglycoprotein. There were two ways to overcome multidrug resistance of tumors through mdr1 genes mRNA and its product Pglycoprotein effectively.Conclusion The clinical test of the unitary way to overcome multidrug resistance of tumors is unsatisfactory, combining different ways to overcome multidrug resistance of tumors will be the hot spot of tumors research in the future.
Objective To review the development of the liver stem cell transplant for the liver regenerative treatment. Methods The transplantationrelated articles about the stem cell classification, repairing mechanisms, administration routes, and existing problems in the liver regenerative therapies reported in the latest literature were extensively reviewed. Results The related liverrepairing stem cells were found to be inside and outside the liver, i.e., the hepatic stem cells and the nonhepatic stem cells. They could repair the liver by the mechanism of the cell fusion or the celltransdifferentiation. The stem cells could be administrated via the portal vein. However, the application of the liver stem cell transplant was restricted by many related clinical problems. Conclusion Further studies are still needed for an improvement of the clinical feasibility for the stem cell transplantation, especially for the liver stem cell transplantation.
目的:探讨超声检查在腹部闭合性损伤内脏破裂出血的应用价值。方法:对92例腹部闭合性损伤内脏破裂出血患者进行全面、细致的超声检查,并收集其手术、病理结果。结果:本组病例超声与手术结果完全相符者83例(占90.2%),基本相符者6例(占6.5%),漏诊3例(占3.3%)。其中脾破裂49例,肝破裂16例,肾破裂14例,胰腺损伤1例,肠破裂6例,复合性内脏破裂6例。92例患者均伴有腹腔积液,超声检出率100％(92／92)。结论:超声能迅速、较准确地对腹部闭合性损伤内脏破裂出血作出诊断,尤其诊断实质性脏器破裂比空腔脏器破裂更有特异性,具有重要的临床价值。
Objective To investigate the immunoregulatory effects of immunonutrient ω-3 polyunsaturated fatty acid (PUFA) and its applications in organ transplantation. Methods Relevant literatures of recent years were reviewed. Results The immunoregulatory effects of ω-3 PUFA can inhibit proliferation and activation of the immunocompetent cells including T cell and B cell, reduce cytokine production, modulate immunologic response, improve graft function, pro-long survival, reduce episodes of rejection, and lessen adverse reactions of immunosuppressor.Conclusion ω-3 PUFA should have wide applications in organ transplantation due to its immunoregulatory effects. However, this research should be further studied.
