Objective To evaluate whether serum cystatin C (SCys C) could be used as an ideal index to assess renal function of renal transplant recipients during posttransplant follow-up.Methods Seventy patients who were followed up for at least 6 months after renal transplantation in our centre were recruited in the study. SCys C and serum creatinine (SCr) were determined during the follow-up period, and glomerular filtration rate (GFR) was measured using an isotope Tc99m DTPA.The correlation between SCys C, SCr and GFR was analyzed. The performance of SCys C and SCr in diagnosing the mild impairment of renal allgraft function (GFR ＜ 1 ml/s) was evaluated using ROC curve. Results Both SCys C and SCr had a linear negative correlation with GFR (r = -0. 82 and -0. 66 respectively, P＜0. 01 ). The sensitivity, specificity and positive predictive values (PPV) of SCys C for diagnosing the mild impairment of renal allgraft function were higher than those of SCr,but the AUC of SCys C did not differ from that of SCr significantly (0. 935 vs. 0. 877, P＞0. 05).Conclusion SCys C could be used an ideal index to evaluate the allograft renal function for its better correlation with actual GFR.

Objective To summarize the clinical experience of combined liver and kidney transplantation (CLKT). Methods CLKT was performed on 22 patients. The orthotopic liver transplantation (LT) was preceded with the classic fashion in 10 patients and piggyback fashion in 12 patients. The renal allograft was implanted to the iliac fossa routinely. After operation, the patients received an induction therapy with anti-CD25 monoclonal antibody or antithymocyte globulin ( ATG) and a maintenance therapy with tacrolimus (Tac), mycophenolate mofetil and prednisone. Results The CLKT was successfully performed on all 22 patients, and the graft function was restored well postoperation. During the perioperative period, an acute rejection episode of liver occurred in one patient and acute renal allograft rejection episode in 2 patients. The Tac toxicity occurred in one patient. The hemorrhage of digestive tract occurred in one recipient and the hemorrhage of peritoneal cavity in one patient. The pleural effusion occurred in 6 recipients. The pneumonia occurred in 2 cases and the peritoneal infection in one patient During a follow-up period of 6 months to 7 years 11 months, three patients died because of cytomegalovirus pneumonia in 2 patients and acute myocardial infarction in, one patient, The 1-, 3-, 5-year survival rate of recipients was 86,4 %, 81.3 %, 72.7 % respectively. Conclusion The CLKT is an effective method for treatment of patients with end-stage liver djsease and chronic renal failure.

Objective To explore the relationship of serum anti-MICA antibody and development of chronic rejection (CR) after renal transplantation. Methods The enrolled 105 patients included 43 cases of CR, and 62 cases of functioning renal allograft as controls. Data including PRA level before transplantation, HLA mismatch, cold ischemic time, SCr at discharge, immunosuppressive regimen,and months after transplantation were analyzed. Blood samples were collected immediately after grouping for anti-MICA antibodies, SCr determination. Acute rejection episodes and renal allograft function which was evaluated by △SCr/M [(SCr at present - SCr at discharge) /months after transplantation) were compared between anti-MICA-antibody positive patients and anti-MICA-antibody negative patients. Results There was no significant difference in gender, age, HLA mismatch, cold ischemic time, immunosuppressive regimen, SCr at discharge, months after transplantation between CR and control groups (P＞0.05). Serum creatinine level and number of antiMICA-antibody positive patients in CR group were significantly increased as compared with those in control group (P＜0.01 ). Acute rejection episodes during the first 3 months after transplantation in anti-MICA-antibody positive patients were significantly more than those in anti-MICA-antibody negative patients (P＜0.05),and the △SCr/M in the former was higher than that in the latter (8.3 +3.6 vs 2.4 ± 2.6, P＜0.05). Conclusion Humoral immunoreaction mediated by MICA partly participates the development of CR after renal transplantation. MICA antibody is a risk factor affecting long-term allograft function.

Objective To investigate a possible association of donor-recipient compatibility for ABO blood group alleles with acute rejection (AR) in renal transplantation. Methods A study comprising 87 pairs of donor and recipient was performed. The ABO genotype A1, A2, O1, O2, and B alleles of renal transplanted recipients and their respective donors were assessed by PCR amplification with sequence-specific primers (PCR-SSP). Accordingly, recipients were divided into donor-recipient ABO genotype matched and mismatched groups. Results The PCR-SSP based types of all cases showed total concordance with their serologically assigned ABO groups. Fifty pairs (57. 5%) were matched for ABO genotype among the 87 pairs of donor and recipient while 37 (42. 5%) were mismatched, including 1 allele mismatch in 31 pairs (83.8%), 2 alleles mismatches in 6 pairs (16. 2%).The incidence of AR was 12.0% (6 cases) and 29. 7% (11 cases) for ABO genotype matched and mismatched transplant patients, respectively ( P ＜ 0.05). After high dose methylprednisolone (MP)treatment, all cases exepienced reversion of AR except a A2O1 recipient receiving kidney from a A1O1enced 4 AR episodes within 3-10 months, and the period of AR was gradually shortened. After high dose MP was administered empirically, even though short-term improvement of renal function was observed, the serum creatinine continued to increase progressively with decreased efficacy of high dose MP. One year after operation the serum creatinine rose to 441 μmol/L. Conclusions Simultaneous definition of the ABO genotype and HLA is highly feasible. The A2 patient is suitable for receiving kidneys from blood group O donors. DNA mismatch for ABO genotype of renal transplant recipients and their respective donors is an independent risk factor for AR. Genotyping of ABO blood group is conducive to prevent AR.

Objective To discuss the risk factor of infection after intracavity lithotripsy in upper urinary tract calculi,and establish a pre-operation warming score system.Methods From Jan.2013 to May 2016,412 upper urinary calculi patients who underwent intracavity lithotripsy were analyzed to evaluate the associated risk factors before operation and infection after operationg by non-conditional logistic regression analysis.The pre-operation warming score system was established by giving those risk factor 1-4 point based on OR value.The best threshold was then determined by ROC curve.Results Diabetes mellitus,infection history,renal calculus and uretero-pelvic junction calculus,stone burden,the degree of hydronephrosis and the gender of female were high-risk factors contributed to infection after intracavity lithotripsy,which were given 3,3,3,2,2,2point respectively based on their OR value(8.660,7.046,3.723,2.675,2.256,1.891),and the patients who got high socre were more likely to suffered infection.The sensitivity and specificity of the wanning score system for infection after intracavity lithotripsy were 74.3％ and 84.0％ respectively when its truncation point was 7.5 point(total score was 15 piont).Conclusions Patients who got more than 7.5 point according to the wanning score system were high risk groups of infection after intracavity lithotripsy.

OBJECTIVE To study the influence of glycogen synthase kinase3β (GSK3β) over expres?sion in the hippocampus on the antidepressant and anxiolytic effects of total flavoids from Xiaobuxin Tang (XBXT-2). METHODS Adeno-associated virus containing GSK3β(S9A) mutation was microinjected into the hippocampus. After three weeks of recovery, GSK3βand p-GSK3βwere detected by Western blotting, and open field test (OFT) was used to evaluate the locomotor activity. Then, AAV group and GSK3β over expression group were divided into administration group and solvent group, respectively. XBXT-2 (100 mg · kg-1) and solvent were ig administered chronically. After 14 d and 16 d of administra?tion, the tail suspension test (TST) and forced swimming test (FST) were used to investigate the influence of GSK3βover expression on the antidepressant effect of XBXT-2, respectively. After 18 d and 20 d of administration, the elevated plus maze test (EPMT) and staircase test (ST) were used to investigate the influence of GSK3β over expression on the anxiolytic effects of XBXT-2, respectively. RESULTS Western blotting analysis showed that the protein level of GSK3βincreased significantly in GSK3βover expression group (P<0.01) compared with AAV group, but there was no significant difference in p-GSK3β. In OFT, the number of crossings and rearings showed no difference between AAV group and GSK3β over expression group. The results of TST and FST showed that compared with AAV group, the immobility time was significantly reduced in AAV+XBXT-2 group (P<0.05, P<0.01), but compared with GSK3β over expression group, the immobility time showed no difference in GSK3β over expression+XBXT-2 group. In EPMT, compared with AAV group, the percentage of entrances and time into open arms in AAV+XBXT-2 group was significantly increased (P<0.01, P<0.05), but compared with GSK3βover expression group, these indexes showed no difference in GSK3βover expression+XBXT-2 group. In ST, compared with AAV group, the number of rearings was significantly reduced in AAV+XBXT-2 group (P<0.05), but there was no difference between GSK3β over expression+XBXT-2 group and GSK3βover expression group. CONCLUSION GSK3βover expression in the hippocampus can reverse the antidepressant effects of XBXT-2 in the TST and FST, and the anxiolytic effects in the EPM and ST.

ObjectiveTo investigate the factors for standard TAC-related nephrotoxicity in renal transplant recipients. MethodsClinical data of 132 patients in TAC-based regiment with a dose of 0. 15-0.3 mg· kg-1 · day-1 and a trough level of 8-11 μg/L during first 2 years post renal transplantation, were retrospectively analyzed. TAC-related nephrotoxicity was diagnosed by renal biopsy and/or clinical criteria. All recipients were divided into 2 groups: TAC nephrotoxicity group (n = 25) and control group (n = 107). Logistic regression analysis was used to rank the relative risk of potential variables including age, gender, delayed graft function (DGF), drug exposure, duration of therapy,liver function, albumin level, hematocrit and gene polymorphism for CYP3A5 and MDR1.ResultsTAC-related nephrotoxicity was found in 25 (18. 9 ％ ) recipients. Univariate and Logistic regression analysis revealed that the influencing factors for TAC-related nephrotoxicity with a standard immunosuppressive regimen and a normal trough level range were identified as: abnormal liver function (RR = 3. 05,95 ％ CI 0. 879-11. 533, P = 0. 024), albumin level (RR = 0. 966,95 ％ CI 0. 994-1. 006, P = 0. 018 ), hematocrit ( RR = 0. 999, 95 ％ CI 0. 998-1. 000, P = 0. 032), CYP3A5 gene polymorphism (RR= 0. 777,95 ％ CI 0. 023-6. 798,P= 0. 032) ,and MDR1 gene polymorphism (RR=0. 654,95 ％ CI 0. 053-7. 109, P = 0. 017). ConclusionLiver function, albumin level, hematocrit, and gene polymorphism for CYP3A5and MDR1as well are influencing factors for TAC-related nephrotoxicity in renal transplant recipients with a standard immunosuppressive regimen and a normal trough level range,in which abnormal liver function is the most important adverse risk factor. These factors should be considered for better individual therapy in renal transplant recipients.
