Objective To explore the effects of penile erectile dysfunction (ED) on the quality of life in male renal transplant recipients.Methods 150 cases of male married recipients undergoing renal transplantation were selected randomly.The recipients were divided into ED group (n =63) and non-ED group (n =87) through the IIEF-5 score.The Short Form-36 Health Status Survey (SF-36)and Hamilton Anxiety Scale were used to compare their living quality and the state of mental health between the two groups,respectively.Results The SF-36 scores in ED group in General Health,Vitality,Social Function,Role Limitation due to Emotional Problems,Mental Health were significantly lower than those in non-ED group (P＜0.05).There were 13 cases in ED group with anxiety disorders (20.6％),significantly more than in non-ED group (3.4％),P＜0.05.Conclusion ED is an important influencing factor for the quality of life in male kidney transplant recipients.

A patient with impaired kidney function after kidney transplantation and received treatment at the First Hospital of Jilin University was retrospective analyzed. The patient was male, 45 years old, and was diagnosed hemolytic uremic syndrome by transplanted kidney biopsy. The patient received cyclosporine A (CsA) as maintenance centered immunosuppression therapy postoperatively. He was admitted because of 1 week acratia followed by 1 day increased serum creatinine level at 1.5 years after transplantation. At 1 day after admission, he was received renal needle biopsy, and underwent 2 days Prednlsolone treatment. After hemolytic-uremic syndrome was diagnosed, CsA was transferred to Tacrolimus (Fk506) with dose of 2 mg/d, and Azathioprine was replaced by mycophenolate, Prednisone was taken orally for 20 mg/d. The function of the transplanted kidney and the change of routine blood tests were observed. After 1 week treatment of the changed Immunosuppression therapy, the function of the transplanted kidney was improved obviously, and the hemoglobin and platelets was decreased during the treatment. The results demonstrated that kidney biopsy is a key method to diagnose hemolytic-uremic syndrome, and adjustment of immunosuppressive agents, replacing CsA with FK506 are effective for postoperative hemolytic-uremic syndrome.

Objective To explore the role of regulatory T cells (Tregs) in skin and heart grafts survival prolongation after different CD47 genotype donor specific splenocytes pretreatment.Methods Mouse skin plus hearts transplantation model was set up by using C57BL/6 as recipients and MHC class I-mismatched bm1 as donors.In CD47-/-DST group,recipients received CD47-/-bm1 splenocytes transfusion at 7th d before transplantation.In CD47+/+DST group,recipients received CD47+/+bm1 splenocytes transfusion at 7th day before transplantation.In control group,recipients only received bm1 skin and heart grafts.The populations of Tregs were analyzed by FACS and immunohistochemistry,respectively.The inhibitory effect of Tregs and anti-donor T cell responses was assessed by MLR.Results Result As compared with control group,the survival time of skin grafts in CD47-/-DST group was slightly longer than in non-DST group (20 days vs.17.5 days,P>0.05),but skin grafts had long-term survival in CD47+/+DST group (46.5 days,P<0.005).The survival time of heart grafts in CD47-/-DST group was similar to that in the control group,and slightly longer than non-DST group (17 days vs.15.5 days,P>0.05),but heart grafts had long-term survival in CD47+/+DST group (42.5 days vs.17 days,P<0.01).At 18th day after transplantation,immunohistochemistry showed that more Tregs infiltration could be observed in CD47-/-DST group,but not in CD47+/+DST group.The number of Foxp3+Tregs from the mice receiving CD47-/-DST increased markedly at 18th day post-transplantation compared to thot from the mice receiving CD47+/+DST (P<0.01),but the ratio of Tregs was decreased significantly (P<0.05).The number of Foxp3+Tregs in both CD47-/-and CD47+/+ DST groups was increased,but there was no significant difference between two groups (P>0.05).As compared with CD47-/-DST group,the ratio of Tregs in lymph node cells in CD47+/+DST group increased significantly (P<0.01).Compared to CD47-/-DST group and control group,anti donor specific T cell proliferation was decreased in CD47+/+DST group at 7th day after transplantation (P<0.05).The inhibitory effects of Tregs were similar among groups.Conclusion CD47 expressed on DST cells plays an important role in grafts survival prolongation.The ratio of Tregs in lymphocytes plays the key role in grafts survival prolongation.but not the number or inhibitory function of single Treg.

Objective To study the effect of serum uric acid (UA) levels on kidney graft function as well as long-term graft survival after renal transplantation.Methods The clinical data of 859 kidney transplant recipients from Jan.2008 to May 2014 were investigated retrospectively.The differences in clinical indexes between normal UA group and hyperuricemia group were compared based on UA levels.Cox regression model was built to analyze the effect of elevated UA on overall graft loss,death censored graft failure and death of patients,respectively.Kaplan-Meier graft survival curve was used to compare the overall graft loss,death censored graft failure and death of patients between normal UA group and hyperuricemia group.Results The average follow-up time was 38.6 ± 17.3 months for 859 kidney transplant recipients.590 (68.7％) recipients were enrolled in normal UA group and 269 (31.3％) recipients were defined as hyperuricemia patients.The average eGFR in hyperuricemia group was significantly decreased as compared with normal UA group (79.4 ± 20.93 vs.94.7 ± 20.55,P＜0.001).Cox regression model showed that if UA level increased per 10 mol/L,the risk of overall graft lost increased 1.070 times (P＜0.001) and the risk of death censored graft failure increased 1.121 times (P＜0.001) accordingly.Kaplan-Meier analysis showed the overall graft loss was dramatically decreased (P =0.009),and the death censored graft failure was significantly decreased (P＜0.0001) in hyperuricemia group as compared with that in normal UA group.The death of patients showed no significant difference between two groups (P =0.638).Conclusion Serum UA levels after kidney transplantation affect graft function as well as long-term graft survival.
