Out of 321 cases of renal transplantation, 12 had hyperacute rejection(3.6%) after operation.Among them transplanted kidneys in 4 caseswere immediately remo-ved during operation, donor kidneys in 7 cases were removed 3-20d postoperation, and rejection in 1 case was controlled after suitable treatment,however donor kidney became atrophied gradually without being removed.Immunosuppressive drugs were discontinued and dialysis v/as restored in tjnv: in all the 12 patients.None of them died of rejection.Clinical diagnosis of hyperacute rejection was confirmed pathologically.Mechanisms, inducing factors, diagnosis and differential diagnosis, and treatment of hyperacute rejection are discussed.

Objective:To observe the influence of a self-designed multiple organ preservation solution,namely Shanghai multi-organ preservation solution(SMO),on the apoptosis of canine renal cortical cells during cold storage and the related mechanism.Methods: Canine kidneys were freshly perfused and separately stored with cold(0-4℃) SMO,hypertonic adenine citrate solution(HC-A),and University of Wisconsin solution(UW solution)(the latter 2 as control).At defined time points during storage,the morphologic changes of renal cortical samples were observed;apoptosis of renal cortical cell was determined by TUNEL;changes of malonldialdehyde(MDA) in cortex homogenate were measured by thiobarbituric acid method;and the activity of superoxide dismutase(SOD) was determined by xanthine oxidase method.Results: Pathologic assessments indicated that the kidney damage was similar in 3 groups within 24 h.The kidney tubular cell swelling and necrosis in SMO group and UW group were slighter than those in HC-A group after stored for 2 days.With the prolongation of storage time,apoptosis increased in all groups,with the apoptotic index of SMO group significantly lower than that of HC-A group(P

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.

0.05).The acute rejection rates in non-dialysis group was significantly lower than that of dialysis group(19.53% vs 34.27%,P0.05).The 1 year survival rates of patient/graft were 98.44% in non-dialysis and(97.72%/)95.96% in dialysis group(no significance);the 3 year survival rates of patient/graft were 96.23% in nondialysis and(94.4%/88%) in dialysis group(no significance).Conclusion:Renal transplantation without dialysis can avoid the dialysis complications and transfusion-induced sensitization,and reduce the risk of hepatitis infection as well as the acute rejection rate;while its patient/graft survival rate is similar to that of dialysis renal transplantation,making it feasible for clinical application.

Objective To inquire into the diagnosis and management of renal angiomyolipoma.Methods The 22 cases of RAML were studied restrospectively.Results The diagnosis accuracy was 54.5% for B ultrasound and 81.8% for CT,18 were diagnosed as RAML and 4 were misdiagnosed as renal cell carcinoma preoperatively,of which 3 were diagnosed as RAML based on intraoperative frozen section study.11 had been performed enuoleation,7 partial nephrectomy,3 nephrectomy and 1 radical nephrectomy. Conclusions CT is the first line imaging method for RAML.the cow fatty component,intratumor hemorrhage and small tumor are the main canse of misdiagnosis in RAML.careful analysis to clinical feature and imaging data,intraoperative frozen sect,ion study can avoid misdiagnosis.nephron sparing surgery is the best operative management.

Objective To define the relationship between genes expression of 5 immune effector molecules and acute rejection of renal allografts. Methods The magnitude of intragraft Fas, Fas ligand (FasL), granzyme B(GB) , perforin(P) and T cell intracellular antigen-1 (TIA-1) mRNA were quantified by competitive PCR in 42 samples. Results were expressed as the ratio of picograms of target gene to picograms of ?-actin, and were compared with the histological diagnosis based upon Banff criteria. Results Of all 42 tissues, the transcripts were detectable in 41 for Fas, 11 for FasL, 19 for GB, 33 for P and 27 for TIA-1. Intragraft expression of FasL, GB, P and TIA-1 but not Fas was significantly elevated in acute rejection group as compared with chronic rejection group ( P

To study the diagnosis of cytomegalovirus (CMV) infection after renal transplantation and the effects and side effects of preventive use of foscarnet (PFA). ELISA assay was used to determine active CMV infection (IgM+,IgG+) and inactive CMV infection (IgM-,IgG+). Seventy four cases of active CMV infection and 25 of inactive CMV infection were selected to receive PFA treatment. Besides, 10 cases of inactive CMV infection without PFA treatment served as a control group. The results showed that the serological tests turned negative in subclinical patients in active stage after 12 5 days of treatment. In those patients with clinical symptoms, infection was controlled in 34 patients after 15 days of treatment. In another 2 patients, serology turned negative after 1 month of treatment, and no recurrence found one year later. In patients in inactive stage, IgM became positive, but with no symptoms, one year after treatment. At the same time, 3 patients in the control group turned into active infection after 1, 2 and 3 months. The results suggested ELISA assay was a good method to determine serum CMV IgG and IgM at present; PFA could definitively control active CMV infection quickly, and no recurrence was found during 1 year follow up; PFA might prevent reversion of serological indexes in patients with inactive infection. Moreover, PFA did not impose damage to the function of the renal graft, and nor interfered with the metabolism of blood calcium and cyclosporine A. Thus, PFA is a safe and effective drug to treat CMV infection.

Objective To retrospectively analyze the effectiveness and safeness of tension-free vaginal tape(TVT) as a treatment for female stress urinary incontinence (SUI) with minimal injury. Methods A longitudinal incision of 1.5cm was made through vaginal mucosa at the midsection of the urethra, and a suspension tape was inserted in 40 SUI patients. Results Thirty four out of 40 patients recovered completely without urinary retention and SUI. Two patients experienced mild urinary retension 2 weeks postoperative, and another patient with similar complaint 3 months after the operation. The symptom was totally alleviated by urethral dilatation. SUI symptom was improved markedly in 1 patient. In 4 patients, bladder perforation occurred during the operation. One patient experienced vaginal mucosa desquamation, and it healed spontaneously. One patient died of myocardial infarction 5 days after the operation. Conclusion TVT seemed to be a good method with minimal injury, with little pain, good result, less complications and high safety.

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.
