快速供肝切取与修整的外科技巧

目的总结肝脏移植供肝的快速切取和修整经验。方法分析2004年共186例快速供肝的切取和修整的资料。快速切取技术采用原位腹主动脉、肠系膜上静脉灌注附加下腔静脉引流，快速切取供肝，4℃UW液中保存和修整肝脏。结果供肝热缺血时间为3～10min，平均4．5min；冷缺血时间平均为3-16h，平均7h。供肝的修整时间为26～90min，平均46min。供肝修整时发现肝动脉解剖变异20例。结论快速供肝切取法要求术者技术娴熟、动作迅速和准确，可最大限度地减少供肝热缺血时间。快速切取法能保证供肝的质量和确保供肝切取的成功。     

中药膳食配合运动干预对肥胖性脂肪肝的影响

目的 探讨中药膳食配合运动干预对肥胖性脂肪肝的影响。方法 将68例脂肪肝患者随机分为对照组和观察组各34例。对照组常规给予低脂饮食和易善复、大黄庶虫丸等降酶保肝治疗；观察组按常规方法治疗外，采用中医辨证施食予以活血化淤、健脾利湿的中药膳食疗法配合运动干预．疗程均为1年。结果 治疗后观察组体重、甘油三酯、总胆固醇、谷丙转氨酶等显著低于对照组（均P〈0．01）。结论 中药膳食配合运动干预对肥胖性脂肪肝疗效显著。     

肝组织HBVDNA定量检查的临床意义

由于对HBV感染的认识正在不断深入，抗病毒治疗急待寻找判定效果可靠的方法，HBVDNA检测，特别是血液和肝组织定量检测显得极春重要。不加选择对HBV感染作肝活检时留取小粒肝组织，同时采血作HBVDNA定量检查。急慢性HBV感染病例均示肝组织内HBVDNA检查明显高于血内检出率，同时肝组织HBV含量明显高于血液的含量。肝组织检测HBVDNA可以明显提高HBV感染诊断率，血内HBVDNA阴转时不能说明肝组织内亦已阴转，血内HBVDNA阴转不宜随即停止治疗。     

Emerging Issues in Hepatitis C Virus-Positive Liver and Kidney Transplant Recipients

Hepatitis C virus (HCV) infection is a major health care issue in liver and kidney transplantation. Besides negatively affecting both patient and graft survival, HCV is associated with a heightened risk for new onset diabetes mellitus (NODM). The mechanisms underlying the diabetogenicity of HCV are complex but are likely to involve insulin resistance caused by inhibitory actions of the virus on insulin regulatory pathways in the liver. The resultant glucose dysregulation is an important determinant of increased morbidity and mortality in liver and kidney recipients. This review highlights the concerns for outcomes in HCV-positive liver and kidney transplant patients with particular focus on the interrelationship between hepatitis C and diabetes. Data about the potential role of calcineurin inhibitors, corticosteroids and mycophenolate mofetil in HCV infection and HCV-associated NODM will also be discussed.     

A case of cystadenocarcinoma of the liver

A case of cystadenocarcinoma of the liver is reported. The patient was a 73-year-old woman in whom a tumor was detected in the lateral segment of the liver during a health examination. Ultrasonograms and computed tomograms showed a multilocular cystic mass. Magnetic resonance imaging (MRI) showed a multilocular lowintensity mass, including a high-intensity portion and a portal branch compressed by the tumor. MRI with gadolinium showed an enhanced cyst wall. The cystic part of the tumor became smaller and the solid part became larger over a 1-month period, indicating that the tumor was malignant. Subsegmentectomy (S₃) was performed and cystadenocarcinoma with cystadenoma was diagnosed by histopathological examination. Identification of changes in the appearance of a tumor should be helpful for the differential diagnosis of cystadenoma and cystadenocarcinoma.     

Apparently increased trough levels of tacrolimus caused by acute infantile diarrhea in two infants with biliary atresia after liver transplantation

Two infants with biliary atresia who exhibited three-fold increased trough levels of tacrolimus and required reduced doses during episodes of acute infantile diarrhea within 5 months of liver transplantation are described. The cause of the increase was not explained simply by hemoconcentration as a result of significant loss of extracellular fluid during these episodes. It does highlight an important issue: that of the continuing need to carefully monitor the trough levels of tacrolimus in such infants.     

放射性肝纤维化过程的定量研究

经＾６０Ｃｏγ线照射大鼠肝区，通过光镜、电镜和图像分析仪、宣研究了照后１年肝脏的病理改变。结果表明，３０Ｇｙ组在照射后１年内逐渐发生了放射性肝纤维化病变。在肝纤维化发生过程中，肝细胞内糖原颗凿含量进行性减少，间质中胶原纤维含量进行性增加，网状纤维于照射１－３个月呈进行性增加。     

肝积颗粒合介入治疗原发性肝癌的临床观察

目的：观察肝积颗粒合介入治疗原发性肝癌气虚血瘀证的临床疗效。方法：将符合研究条件的患者随机分为治疗组（30例）和对照组（30例），分别采用肝积颗粒保介入治疗和单纯介入治疗，观察两组的近期临床疗效、远期生存时间以及T细胞亚群、AFP值的变化情况。结果：治疗组瘤体缓解率为20．00％、稳定率为90．00％，对照组分别为16．67％、63．33％，其中，瘤体稳定率两组差异有显著性（P＜0．05），治疗组在减轻临床症状，延长生存时间、升高CD3、CD4值等方面优于对照组（P＜0．05），两组AFP值变化比较，差异无显著性。结论：肝积颗粒联合介入治疗原发性肝癌气虚血瘀证，可提高临床疗效，改善临床症状，增强机体免疫功能，延长生存期。     

电镜下的乙型肝炎表面抗原

本文对81例乙型肝炎病人的肝活检组织进行了电镜观察,发现HBsAg的阳性率达93.8％。电镜下,HBsAg细丝不仅有一般的管状细丝型,还有分枝管型和管泡型,而且CAH病人肝组织不易找到HBsAg丝(易见者仅9％),CPH,CLH则多数(79.5％)为易见及可见,二者有高度显著性差异(P<0.01)。     

同种原位肝移植围手术期的处理

目的 总结我院自1999年8月以来,开展的3例同种异体原位肝移植（Orthotopic livertransplantation,OLT）围手术期的处理过程及经验体会。方法　2例原位肝移植、1例肝-肾联合移植术。均在术前12h口服环孢霉素A（CsA）和骁悉（MAP）,术中用甲基强的松龙（MP）1000 mg静脉冲击防止排斥,术后MP+CsA+MAP三联用药。结果 ①文中3例病人手术均获成功,其中2例原位肝移植病人存活至今,生活质量良好。肝肾联合移植病人于术后第76d死于严重混合感染。②移植肝的功能维护是肝移植术后处理的重点,其中包括急性排斥反应的诊断和处理,以及其它可能引起肝移植肝功能损害、衰竭等问题的处理。③全身非移植器官的功能恢复:包括呼吸系统、感染、出血、胸水、腹水等并发症的处理过程。结论 肝移植围手术期的处理是肝移植成功与否的关键,其中包括肝移植的排斥反应及各系统的功能支持与维护。
