Objective To analyze the epidemiographic features of malignant tumors of urinary system in renal allograft recipients in our center.Methods A retrospective analysis was performed on 3150 patients who received renal transplantation between June 1978 and Autumn 2006.Twelve cases of urinary tumors were selected for study.Results Among 3150 recipients,33(1.05%)were diag- nosed as malignancies including 12(0.38%)cases in urinary system.The mean age of these patients when diagnosed as urinary tumors was 58.3?4.6(range 48-66).The mean duration of immunosup- pressive treatment was 62?18(range 26-120)months.Six cases received cyclosporine A+azalthio- prine+prednisone(CsA+Aza+Pred),5 cases cyclosporine A+mycophenolate mofetil+prednisone (CsA+MMF+Pred),and one case tacrolimus+mycophenolate mofetil+prednisone(FK506+MMF +Pred).Surgical treatment was carried out in 11 patients.Ten of them were still alive.One case died of cerebral hemorrhage.Conclusions Malignant tumors of urinary system,especially TCC is an im- portant complication in renal transplantation in our center.The occurrence of malignant tumors is inti- mately related to immunosuppressive treatment.The immunological status of patients after renal transplantation should be evaluated in follow-up studies.The treatment consists of complete resection of the mass,decreases of immunosuppressants,chemotherapy or radiotherapy.

Objective To compare the short-term clinical outcomes of hand-assisted laparoscopic surgery(HALS),laparoscopic-assisted surgery (LAS)and open surgery(OS)for colorectal cancer treatment. Methods The clinical data of 74 patients underwent HALS,LAS and OS for colorectal cancer treatment between October 2011 and December 2015 were assessed retrospectively. All the surgeries were performed by the same surgical team. The intraoperative details,postoperative recovery,postoperative complications,oncologic results and cost were compared among the three groups. Results A total of 24 patients in HALS group,25 patients in LAS group and 25 patients in OS group were finally included. The gen-eral data and oncologic baseline were comparable among the three groups. The comparative results showed that the operative time increase d and in-cision length shortened gradually in OS group,HALS group and LAS group(P<0.05). HALS group was favor of less number of trocars used com-pared with LAS group(P<0.05),but there was no statistical difference of the conversion rate between the two groups(P>0.05). In terms of post-operative recovery,postoperative complications and oncologic results,there was no statistical difference between the three groups(P>0.05). As for cost,the total cost and operative cost of OS group were lower than HALS group and LAS group(P<0.05),but there was no significant differ-ence between HALS group and LAS group(P>0.05). The material cost increase gradually in OS group ,HALS group and LAS group(P<0.05), and there was no significant difference on the part of other cost among the three groups(P>0.05). Conclusion HALS,LAS and OS are compen-satory with each other,and clinicians can choose the reasonable procedure according to personal proficiency and situation of patients.

Objective To investigate the incidence of postoperative hepatic metastasis,clinicolpathological characteristics and the prognosis for pancreatic cancer. Methods Totally 83 cases with pancreatic cancer admitted in our hospital during January 2007 to September 2012 was retro?spectively analyzed according to clinicolpathological data. Results Postoperative liver metastasis occurred in 31 cases with a metastatic rate of 37.3%. The size(χ2=9.606;P=0.002),vascular invasion(χ2=4.794,P=0.029)and UICC stage(χ2=5.318,P=0.021)were correlated with he?patic metastasis. Univariate analysis revealed the poor prognosis in pancreatic cancer patient with hepatic metastasis(χ2=9.967,P=0.002). Cox re?gression analysis revealed hepatic metastasis as an independent prognostic factor(P=0.001). Conclusion Pancreatic cancer has a high possibility of hepatic metastasis. Postoperative hepatic metastasis was one of the independent factors for the prognosis of pancreatic cancer. Tumor size,vascular invasion and UICC stages were risk factors for postoperative liver metastasis of pancreatic cancer.

The diversity in Tibetan kefir grains and dynamics of the microbial community during the fermentation of Tibetan kefir by PCR-DGGE fingerprinting technique were studied.The results showed that bacterial community of Tibetan kefir grains was more complex than that of yeast.The bacteria communities between different Tibetan kefir grains showed 78%～84% similarity, and yeast 80%～92%.Bands B, E and N of DGGE profiles of the microbial community during fermentation of Tibetan kefir were present throughout the fermentation.Analysis of sequence date showed the majority of the DGGE bands of bacteria community corresponded to LAB, and the most intense band (band E) was completely homology to Lactococcus lactis.
