Objective To review the researches of donor nerve’s promoting effect on regeneration of reci pient nerve in end-to-side neurorrhaphy at home and abroad. Methods The latest original l iterature concerning donor nerve’s accelerating effect on regeneration of recipient nerve was extensively reviewed. Results Proper nerve cutting may promote nerve regeneration. But how to quantize the cutting volumn was still a challenge. Conclusion It is important to research thedonor nerve in neurorrhaphy, which can provide evidence for cl inical neurorrhaphy so as to achieve good results.
Objective To discuss venous drainage types of median hepatic lobe and their guiding significances on the selection of grafts. Methods Between April 2005 and March 2009, 109 potential living donors underwent 3-dimensional reconstruction of computed tomography (CT) and the volume of graft was determined in the center of organ transplantation of Ruijin Hospital. The venous drainage types of median hepatic lobe of each donor were analyzed by the computer-based liver operation-planning system in detail to assign middle hepatic vein (MHV) types according to Marcos classification and venous types of Ⅳb segment according to Nakamura classification. Results The branching pattern of MHV was divided into 3 types: Type Ⅰ and Ⅱwere relatively more accounting for 44.0% （48/109）, 37.6% （41/109）, and type Ⅲ was fewest 〔18.3% （20/109）〕. There were no significant differences in volume of whole liver, volume of left liver or left liver/total liver volume ratio among various types of MHV of the donor (Pgt;0.05). Ⅳb vein was also divided into 3 types: The most common was type Ⅰ, accounting for 72.4% (79/109); Type Ⅱ 〔12.8% （14/109）〕, type Ⅲ 〔14.7% （16/109）〕 were relatively fewer. At last, 37 donors provided right liver, for Marcos Ⅰ, Ⅱ, and Ⅲ type of donors, donors remained with MHV was 12/17, 8/11, and 5/9; for Nakamura Ⅰ, Ⅱ, and Ⅲ type of donors, those number were 16/26, 4/6, and 5/5. Conclusion In adult-to-adult living donor liver transplantation, there may be great significances in accordance with Marcos and Nakamura typing results to harvest right lobe liver graft with or without MHV.
目的总结心脏移植和双肺移植供体心肺同时摘取的经验。 方法解放军第一八一医院心脏中心2012年完成3例同一供体心肺同时摘取，分别完成心脏移植和双肺移植各3例。3例供体为脑死亡，阻断供体升主动脉和主肺动脉后，同时灌注保护液，心脏保护应用组氨酸-色氨酸-酮戊二酸心脏停搏液（HTK液），肺保护应用低钾右旋糖酐液（LPD液）；供体心肺热缺血时间为5 min，供心冷缺血时间分别为252 min、323 min和375 min，供体肺冷缺血时间分别为610 min、679 min和738 min；3例心脏移植均采用双腔静脉吻合法，3例肺移植均采用序贯式双肺移植。 结果3例心脏移植均存活；肺移植2例存活，1例死亡。存活患者出院后生活质量良好，随访8～13个月未出现感染、急性排斥反应等并发症。 结论供体心肺同时摘取，同时灌注后分别修剪并再次灌注，分别保存运输，心脏移植和双肺移植可取得满意效果。
【Abstract】Objective To investigate the effect of donor blood transfusion on inducing pancreatic allograft tolerance in outbred rat model. Methods Wistar male rats were used as blood and pancreas donor, and diabetic recipients. One ml of donor blood injected into abdomen of diabetic recipients on the day of transplantation and azathioprine given 2 days pretransplant and continued for three days. Results Pancreas allograft survival was significantly prolonged (28 to 112 days, media survival time 64.2 days). One ml of donor blood alone injected into the abdomen and azathioprine given alone 2 days pretransplant did not improve allograft survival (media survival time 9.8 vs 10.2 days). Conclusion Donor blood injected on the day of transplantation and a 3 days course of azathioprine started 2 days pretransplant have b synergism in inducing long term graft survival in this rat model.
Objective To approach whether the postoperative recovery processes of the living donors and hepaticpatients after right hepatectomy is similar. Methods The clinical data of consecutive cases from 2009 to 2010 in our liver transplantation center was retrospectively analyzed， including 40 cases who donated the right lobe without the middlehepatic vein （living donor liver transpalntation-donor group， abbreviated as LDLT-D group） and 80 hepatic patients forright hepatectomy， in which 40 cases were hepatic patients without cirrhosis （liver disease-noncirrhosis group， abbreviatedas LD-NC group） and 40 cases were hepatic patients with cirrhosis （liver disease-with cirrhosis group， abbreviated asLD-WC group）. Preoperative liver function and general clinical data， intraoperative blood loss and transfusion， postoper-ative liver function， and complications were statistically analyzed in this study. Results The preoperative parameters of three groups were comparable. LDLT-D group experienced more intraoperative bleeding than LD-NC group 〔（765±411） mL vs. （584±242） mL， P=0.008〕， and was similar to LD-WC group 〔（666±224） mL， P=0.136〕. However， the average amount of blood transfusion products was similar among the 3 groups （P=0.108）. The levels of total bilirubin and INR of LDLT-D group were higher than LD-NC group and LD-WC group on the first and third day after operation （P＜0.05）. The levels of ALT and AST of LD-WC group were higher than LDLT-D group and LD-NC group （P＜0.05）. The overall postoperative surgical morbidity incidence of LDLT-D group， LD-NC group， and LD-WC group were 30.0%（12/40）， 27.5% （11/40）， and 37.5% （15/40） respectively， and were not statistically significant （P=0.606）. However， the ClavienⅢcomplication rate of LD-WC group was higher than LDLT-D group and LD-NC group 〔27.5% （11/40） vs. 7.5%（3/40） and 10.0% （4/40）， P=0.024〕. Conclusions Liver function of living donors is injured more seriously during the early postoperative period. The total complication rates after right hepatectomy are similar among the living liver donation and hepatic patients with or without cirrhosis. However， the serious complication rate of cirrhotic liver recipients is higher than living donors and patients without cirrhosis.
ObjectiveTo more comprehensive understanding the survival situation of donors after liver transplantation, which can be applied to clinical diagnosis and treatment. MethodsThe related literatures in recent years of living donor liver transplantation (LDLT) postoperative complications, quality of life, and liver regeneration were reviewed, and the donors postoperative survival situation were investigated. ResultsLDLT has become an option, It is safe and feasible for healthy adults to donate partial liver for LDLT. ConclusionsDonor postoperative survival situation is very important, and it affect the development of LDLT.To improve donors postoperative survival situation, we still need more efforts.
