Objective To analyze the outcomes of renal transplantation from donation after citizen death (DCD) in our single center.Method We retrospectively investigated the recipient outcomes of renal allografts from DCD.Between November 2010 and 31st December 2014,our institution performed 242 renal transplants from DCD.Outcome variables (survival of recipients/allografts and adverse events) and characteristics of marginal donor transplants were analyzed.Result There were 139 males and 44 females in the enrolled 183 donors,and the range of age was from 2 days to 68 years.183 donors included 102 cases of donation after brain death (category Ⅰ),22 cases of donation after circulatory death (category Ⅱ) and 59 cases of donation after brain death followed by circulatory death (category Ⅲ).Utilizing these renal allografts,we performed 242 kidney transplantations including 237 single kidney transplants and 5 pediatric en bloc kidney transplants.The age of recipients ranged from 12 to 64 years.The data indicated that the 1-year recipient/allograft survival rate was 93.8% and 90.5%,respectively.The rate of delayed graft function (DGF) was 33.1 %,higher than that from executed prisoners allografts (23.6%,P<0.05).However,the rate of 1-year acute rejection,interstitial pneumonia and the other adverse events (urinary fistula,ureteral obstruction and cardiac and cerebral vascular accident,etc.) was similar to that from executed prisoners allografts.In addition,good results from pediatric and elder donor renal transplantation were shown in our data,even though the discard rate of elder donor kidney was high.Conclusion By comprehensive evaluation,strictly screening donors and enhancing the rnanagenent of donors,the long-term survival of recipients may be prolonged and the incidence of DGF and primary graft non-function (PNF) may be decreased.The marginal donors from pediatric and elder DCD donors could be utilized in clinical transplantation safely and effectively as long as reasonable evaluation was carried out.

CD46 is not only identified as a complement regulatory protein which protects host cells from complement attack, but also a new co-stimulatory molecule for human T cells. CD3/CD46 co-stimulation can induce a T-regulatory 1 cell (Tr1)-specific cytokine phenotype in human CD4(+) T cells. However, the role of CD46 as a co-stimulatory molecule in the modulation of the acquired immunity, such as transplant immunology, remains unclear. In this study, CD4(+) T cells were isolated from human CD46-transgenic C57BL/6 mice by magnetic-activated cell sorting, and further induced by anti-CD3, anti-CD28 and anti-CD46 antibodies respectively, and anti-CD3/anti-CD28 antibodies, anti-CD3/anti-CD46 antibodies, or the monoclonal antibody panel against CD3/CD28/CD46. The levels of interleukin-2 (IL-2), gamma-interferon (gamma-IFN), interleukin-10 (IL-10) and transforming growth factor-beta (TGF-beta) were detected in the supernatants of different groups. Suppression of allogeneic T cell proliferation were assessed by using mixed lymphocyte reaction (MLR) assay, in which monoclonal antibodies against CD46 were added to the culture. The results showed that CD3/CD28, CD3/CD46 and CD3/CD28/CD46 co-stimulation could significantly induce stronger proliferation of T cells than CD3 stimulation (P<0.05), and CD3/CD28/CD46 co-stimulation significantly increased the proliferation of T cells when compared with CD3/CD28 or CD3/CD46 co-stimulation (P<0.05 for each). IL-2 and gamma-IFN levels were much higher in CD3/CD28 co-stimulation group than in CD3, CD28, CD46 and CD3/CD46 groups (P<0.05 for each). IL-10 and TGF-beta levels were dramatically increased in CD3/CD46 co-stimulation group as compared with those in the CD3, CD28, CD46 and CD3/CD28 groups (P<0.05 for each). CD3/CD46 co-stimulation significantly inhibited the T cell proliferation and allogenic immune responses through the secretion of IL-10 and TGF-beta in MLR (P<0.05). These results suggested that CD3/CD46 can induce Tr1 cells to modulate allogenic immune responses, and it may become a novel target for the development of new therapeutic approach for T-cell-mediated diseases. CD46 plays an important role in regulating the T cell-mediated immune responses by bridging innate and acquired immunity.

Objective To investigate the immunosuppressive regimen of cyclosporine A(CsA) reduced or withdrawn in the HBV-DNA positive kidney transplanted patients. Methods The program of 64 kidney transplanted patients with HBV-DNA positive from Jan,2004 to Dec,2007 were analyzed, the patients were divided into 3 groups ①CsA + MMF group(A group) ;②FK506 + MMF group(B group) ;③low dose of CsA + SRL group(C group). All the patients received entecavir to resist HBV replication and were followed up for acute rejection incidence,liverfunc- tion and HBV-DNA test for 6 months. Results There was no significant difference in 3 groups about acute rejection incidence rate. Liver dysfunction took place in 12 patients of A group (80%) ,8 patients(53%) in A group HBV-DNA became negative; 5 patients (20%) in B group appeared the liver dysfunction, HBV-DNA became negative in 18 patients(75%). 4 patients in C group(16%) appeared liver dysfunction sHBV-DNA was negative in 18 patients (72%) of C group. Conclusion It was safe and efficient for the immunosuppressive regimen of cyclosporin A re-duced or withdrawn in the HBV-DNA positive kidney transplanted patients,not increasing the incidence of acute re-jection and aggratating the liver injury.

Objective To evaluate the efficacy of comprehensive treatment for liver cancer recurrence and metastasis after liver transplantation, and investigate the risk factors affecting the lifespan of patients with liver cancer recurrence and metastasis. Methods Of 29 patients with liver cancer recurrence and metastasis after liver transplantation, 11 patients in the comprehensive treatment group were treated by TACE, microwave coagulation, radiotherapy or hepatectomy, and the remaining 18 patients were classified into chemotherapy group. The differences in efficacy between the 2 treatment modalities were compared, and the factors influencing the patients' lifespan were analyzed. Results Compared with patients in the chemotherapy group, patients in the comprehensive treatment group had significantly longer lifespan after liver cancer recurrence and metastasis (t = 5. 617, P < 0.01). TNM staging, pathological classification, time of postoperative recurrence and metastasis and treatment method were the factors that influence the lifespan of patients with liver cancer recurrence and metastasis after liver transplantation (t =2.843, 3.061,22.781,5.617, P <0.01). Conclusions Comprehensive treatment could prolong the lifespan of patients with liver cancer recurrence and metastasis after liver transplantation. The efficacy of comprehensive treatment is superior to that of the chemotherapy.
