ABSTRACT
<p><b>BACKGROUND</b>Delayed graft function (DGF) is common in kidney transplants from organ donation after cardiac death (DCD) donors. It is associated with various factors. Determination of center-specific risk factors may help to reduce the incidence of DGF and improve the transplantation results. The aim of this study is to define risk factors of DGF after renal transplantation.</p><p><b>METHODS</b>From March 2010 to June 2012, 56 cases of recipients who received DCD kidneys were selected. The subjects were divided into two groups: immediate graft function (IGF) and DGF groups. Transplantation factors of donors and recipients as well as early post-transplant results of recipients were compared between the two groups.</p><p><b>RESULTS</b>On univariate analysis, preoperative dialysis time of recipients (P < 0.001), type of dialysis (P = 0.039), human leucocyte antigen (HLA) mismatch sites (P < 0.001), the cause of brain death (P = 0.027), body mass index (BMI) of donors (P < 0.001), preoperative infection (P = 0.002), preoperative serum creatinine of donors (P < 0.001), norepinephrine used in donors (P < 0.001), cardiopulmonary resuscitation (CPR) of donors (P < 0.001), warm ischemia time (WIT) (P < 0.001) and cold ischemia time (CIT) (P < 0.001) showed significant differences. Recipients who experienced DGF had a longer hospital stay, and higher level of postoperative serum creatinine.</p><p><b>CONCLUSION</b>Multiple risk factors are associated with DGF, which had deleterious effects on the early post-transplant period.</p>

<p><b>OBJECTIVE</b>To study the clinical significance of piggy-back liver transplantation in treating acute liver failure (ALF).</p><p><b>METHODS</b>Fifteen ALF patients (13 caused by HBV and 2 with acute Wilson disease) had piggy-back liver transplantations (PBLT) in our hospital from Sept 1999 to Feb 2006. The outcomes of these patients were retrospectively analyzed.</p><p><b>RESULTS</b>One year survival rate of the 15 patients was 87% (13/15). Excellent outcome was achieved in the 2 acute Wilson disease cases: their corneal Kayser-Fleischer rings disappeared and serum ceruloplasmin levels returned to normal. Among the 15 cases, one died of severe pulmonary infection and another died of multiple organ system failure on the 6th and 11th postoperative days. HBsAg positivity was observed in 13 cases before liver transplantation. Eleven patients survived and later received anti-HBV treatment recommended by the American Association for the Study of Liver Diseases. Their HBsAg became negative.</p><p><b>CONCLUSION</b>Liver transplantation is an effective therapy for ALF and can improve survival rate significantly.</p>

Objective To explore the effect and indication of splenectomy in liver transplantation.Methods From January 2001 to April 2006,260 patients underwent piggyback orthotopic liver transplantation(PBOLT),and 28 patients had undergone combined PBOLT and splenectomy(splenectomy group).These patients were compared to 56 randomly selected non-splenectomy patients from the same transplant period,meaningly two controls were se- lected for every non-spleneetomy case.Two groups were analyzed with respect to rate of infection and survival rate, as well as biopsy-proven acute allograft rejection within 30 days after transplantation.Results Rate of infection in the splenectomy group was higher than that in the non-splenectomy patients(85.7% vs 55.4%,P
