Academic Journal of Second Military Medical University 1985;0(06):-
UW solution has bean considered the gold standard for abdominal organ preservation. Celsior solution and HTK solution, with low potassium and low viscosity, are becoming more widely used in the preservation of the kidney, liver and pancreas, and are gradually accepted as an ideal alternative for UW solution. Recent studies have found that addition of trophic factors can attenuate hypothermic ischemic injury to the donor organ, thus improving the preservation outcome. This paper reviews the progress in laboratory research and looks foward to the clinical application of multi-organ preservation solution.

Retrospective analysis of 761 case-times successive color Doppler sonography for 518 renal transplant patients was carried out.six parameters of sonography were used to compare, the CsA-NT hemodynamic changes among the patients with normal function, rejected and hy-dronephrotic kidney.It revealed that during rejection of the rendl srafts, besides an elevation of resistance index(RI)and a decrease of D/S ratio, the velocity and volume of renal blood flow were also slowed down and decreased respectively.After combating rejection, the renal function recovered to normal gradually, and RI dropped below 0.75 subsequently.Otherwise R1 would be persistently elevated, which indicated an irreversible rejection.The diagnosis of acute rejection was given at RI≥0.83, with the sensitivity rate being 82.70%and specificity being 80.10%.It was suggested that RI is a relatively sensitive and relialble parameter for the diagnosis of rejection.In combination with the clinical manifestations RI is of great important clinical value for the early diagnosis and treatment of acute rejection.

Conclusions The kidney transplantation without prior dialysis offered comparable patient/graft survival to kidney transplantation with prior dialysis and avoided the dialysis complications and sensitization of transfusion, while reduced the risk of acute rejection. Therefore, uremic patients may be considered to receive the kidney transplantation without prior dialysis in clinic.

Objective:To study the differential gene expression pattern between autosomal dominant polycystic and normal kidney tissue,and to deduce the etiological factor and treatment for autosomal dominant polycystic kidney disease(ADPKD).Methods: The cDNA probes were prepared by labelling normal kidney tissue mRNA and ADPKD tissue mRNA with Cy3-dUTP and Cy5-dUTP separately through reverse transcription.The probes were then hybridized with the DNA microarrays(PCR products of(4 096) human cDNAs onto specially treated glass slides) and the fluorescent signals were scanned with ScanArray 4000 scanner.Semi-quantitive RT-PCR was performed to test the expression level of 4 related genes.Results: Of the 4 096 genes screened,463 genes showed obvious changes.Expression of 206 genes was upregulated in the polycystic kidney tissue,especially cyclin D_(2),MMPs,TIMP1 and fibroblast activation protein;expression of 257 genes was downregulated,especially phosphatase 1A and acid phosphatase 1.The expression of genes tested by RT-PCR was in accordance with those detected by cDNA microarray.Conclusion: ADPKD may be related to the upregulation of cyclin,MMPs,and various kinds of growth factors,and drugs like inhibitors of CaM and MMPs might have therapeutical effects on ADPKD.

Objective To review the kidney transplantation performed in our center and analyze the risk factors affecting long-term allografts survival. Methods Thirty two relative variables were analyzed by SAS statistical software. Using Log-Rank method, the influence of these variables on short and long-term grafts survival was investigated. A Kaplan-Meier analysis was used to estimate the 1-, 3-, 5-, 10-year graft survival rate and its half-life. Proportional hazards regression analysis (Cox model) was used to assess and rank the relative risk of potential variables.Results The 1-year, 3-year, 5-year, 10-year grafts survival rate was 82.5 %, 75.2 %, 65.5 % and 48.4 % respectively. When excluding the patients died with functioning grafts, the 1-year, 3-year, 5-year, 10-year grafts survival rate was increased to 91.0 %, 82.0 %, 75.9 %, 68.5 %, respectively. The mean half-life was 8.78? 0.14 and 14.09? 0.20 years, respectively. By Log-Rank analysis, factors affecting short- and long-term grafts survival were identified as: renal function and duration of which become normal, cold-ischemia time, acute rejection, delayed grafts function, immunosuppressive regimen, complication, infection, the method of anti-rejection therapy. A Cox model multivariate analysis showed that there were 18 factors affecting graft survival.Conclusion New immunosuppressive agent not only has significantly increased short-term graft survival, but also prolonged the long-term survival. Making assurance to get high quality donor organ and minimizing the death with graft function may be the most feasible way to prolong a graft survival at present.
