Objectives:To discuss the observation of patients receiving simultaneous pancreas-kidney transplantation for insulin-dependent diabetes mellitus complicated with end-stage renal failure.　Methods:The patient received simultaneous pancreas-kidney transplantation with enteric drainage of exocrine pancreatic secretions.　Results:The important aspects were as follows: monitoring the functions of the transplanted pancreas and kidney, observing the early characteristics of rejection, especially the pancreas, preventing thrombosis of blood vessels of the transplanted pancreas, digestive tract hemorrhage，pancreatitis, and preventing duodenal fistula. 　Conclusion:By careful clinical observation, postoperative complications could be found earlier, which aided the treatment and improved the prognosis.

Objective To analyze the death causes of cadaveric kidney transplantation recipients. Methods The clinical data of 1400 cases of cadaveric kidney tansplantation between 1978 and 2003 were analyzed retrospectivvely. The death rate, causes and period were analyzed among the died recipients after kidney transplantation. Results 187 patients were died after renal transplantation in this stage with the ratio being 13.36% (187/1400). The death causes contained infection, cardiocerebra l vascular diseases and hepatic failure by turns, and the ratio was 37.97% , 31.56% and 14.97% , respectively. There were 87 ( 46.5% ) death cases w ith normal transplanted-kidney function. Conclusions The leading causes of patients' death were infection, cardiocerebral vascular d iseases, and hepatic failure. About half of these patients were died with normal transplanted-kidney function.

Objective To explore the methods for treating no-functioning renal graft.Methods The management of 240 cases of non-functioning renal graft between 1978 and December 2003 was retrospectively analyzed.Results Twenty-nine recipients with renal failure one month after renal transplantation were subjected to removal of the renal graft. One year after renal transplantation, the recipients with renal failure received resection of the renal graft, 4 were treated with renal artery embolism, and 114 did not receive special treatment.Conclusion The non-functioning renal graft required removal at early stage of renal transplantation. At later stage, no symptomatic cases of post-transplanted renal failure required no management after stopping immunosuppressant. The appropriate management is reserved for the symptomatic cases.

Objective To explore the effects of miRNA-218 on renal cell carcinoma of nude mice in vivo.Methods The pcDNA3.1-miR-218 and its control negative plasmids were stably transfected into renal cell carcinoma cell line A498 and 769-P.These cells were inoculated into nude mice in different groups to observe the changes of body and tumor and to detect the expression of miR-218 in the tissues of nude mice.Results In the A498 cells + pcDNA3.1-miR-218 transfected group,the weight loss of tumor bearing nude mice after 25 days was lower than that in the control group,and the tumor volume was smaller than that in the control group after 10 days (P ＜ 0.05).In the 769-P cells + pcDNA3.1-miR-218 transfected group,the weight loss of tumor bearing nude mice was lower than that in the control group after 19 days,and the tumor volume was smaller than that in control group after 10 days (P ＜ 0.05).The expression of miRNA-218 in bearing nude mice with A498 cells or 769-P cells transfected by miRNA-218 was significantly higher than that in the control group,and the difference was statistically significant (P ＜ 0.05).Conclusion Up-regulation of miRNA-218 expression can inhibit the growth of renal cell carcinoma of nude mice in vivo.

Objective To construct a stable expression plasmids miR-218,to lay the experimental foundation for the expression and mechanism of miR-218 in human renal cell carcinoma.Methods The primers were designed by Has-miR-218 and the miR-218 fragment were amplified by PCR,and then which was connected with the carrier pcDNA3.1 (+) to build a stable expression plasmids.The recombinant plasmids were trasfected into renal cell carcinoma cell line 769-P,and the expression of miR-218 in these cells were detected.Results The plasmids were constructat successfully,which was determind by enzyme digestion and sequencing results.The constructed expression plasmids pcDNA3.1-miR-218 transfection of human renal cell carcinoma cell line 769-P,miR-218 cxpression level of cells was significantly increased after trasfected by recombinant plasmids carrying miR-218 gene (relative expression quantity was 1.64).Conclusion The miR-218 expression plasmids pcDNA3.1-miR-218 were successfully constructed,the plasmids can be applied to the study of miR-218 function and mechanism in renal cell carcinoma.

BACKGROUND: Anemia after kidney transplantation has a clinical incidence rate of 30%-40%, is the important risk factor for cardiovascular diseases and kidney failure after kidney transplantation and is also the independent prediction index of patient's death. OBJECTIVE: To analyze the factors related to anemia after kidney transplantation. RESULTS AND CONCLUSION: In the anemia group (n = 225, 27.2%, aged 26-65 years), the incidence rate of anemia in female and male patients was 23% and 37%, respectively (P < 0.05), 46 patients had hypertension and used angiotensin-converting enzyme inhibitor or angiotensin Ⅱ receptor antagonist and 16 patients had chronic erosive gastritis or upper gastrointestinal tract ulcer, with the human survival rate of 85.3% and kidney failure rate of 25.3%. In the non-anemia group (n = 601, 72.8%, 405 males, 196 females, aged 18-71 years), 35 patients had hypertension and used angiotensin-converting enzyme inhibitor or angiotensin Ⅱ receptor antagonist and 14 patients had chronic erosive gastritis or upper gastrointestinal tract ulcer, with the human survival rate of 92.1% and kidney failure rate of 12.6%. There was significant difference in above-mentioned indices between anemia and non-anemia groups (P < 0.05). These results suggest that gender, age, kidney function, digestive tract disease history, and drug application are closely related to anemia after kidney transplantation.

Objective To explore the effects of miR-218 on biological functions of renal cell carcinoma cell line through regulating the expression levels of miR-218.Methods The pcDNA3.1-miR-218 was transfected into renal carcinoma cell line A498 and 769-P and the expression of miR-218 was detected.The cell activity,invasion,apoptosis and proliferation of transfected renal carcinoma cell line were analyzed in vitro.Results After plasmid transfected A498/769-P renal carcinoma cell line,the expression level of miR-218 (1.99,1.64) was significantly higher than that of the control group (1.00) (t =60.82,10.89,P ＜ 0.000 1) The cell viability (0.90±0.10,0.68±0.06) was lower than that of the control group (1.39±0.14,1.24±0.08) by CCK8 experiment (t =15.02,31.69,P ＜ 0.000 1).The cell invasion was lower than that of control group by Transwell experiment (t =15.78,18.80,P ＜ 0.000 1).The apoptosis ratio was higher by AnnxinV-FITC experiment,the apoptosis ration of control group and transfected group were respectively 0.25 ％,45.77 ％ in A498 cell line and 0.11％,45.57 ％ in 769-P cell line.The proliferation was lower than that of the control group (P ＜ 0.000 1).Conclusion Up-regulation of miR-218 expression can inhibit the growth of renal cell carcinoma cell line in vitro.

To obtain the P8 protein of Rice gall dwarf virus (RGDV) with biological activity, its outer coat protein gene S8 was expressed in Spodoptera frugiperda (Sf9) insect cells using the baculovirus expression system. The S8 gene was subcloned into the pFastBacTM1 vector, to produce the recombinant baculovirus transfer vector pFB-S8. After transformation, pFB-S8 was introduced into the competent cells (E. coli DH10Bac) containing a shuttle vector, Bacmid, generating the recombinant bacmid rbpFB-S8. After being infected by recombinant baculovirus rvpFB-S8 at different multiplicities of infection, Sf9 cells were collected at different times and analyzed by SDS-PAGE, Western blotting and immunofluorescence microscopy. The expression level of the P8 protein was highest between 48-72 h after transfection of Sf9 cells. Immunofluorescence microscopy showed that P8 protein of RGDV formed punctate structures in the cytoplasm of Sf9 cells.
