Résumé
For a long time, urological surgeons have been troubled by the treatment of long proximal and mid ureteral stricture, and the commonly used ileal ureteral substitution and autotransplantation have certain shortcomings. In recent years, the development of autologous graft technique has brought a new hope for these patients. The commonly used autologous grafts or flaps include oral mucosa, intestinal tissue, urogenital tissue, etc. The feasibility and safety of autologous graft technique have been preliminarily verified, but each kind of graft or flap has different advantages and disadvantages. The research progress of autologous grafts or flaps ureteroplasty in this article was reviewed and the related problems of this technique were discussed.
Résumé
Taking the curriculum "society, the individual & medicine" in university of Ottawa faculty of medicine as an example, the cultivation models for comprehensive quality of medical students in China and Canada was compared. In University of Ottawa faculty of medicine, the curriculum "society, the individual & medicine" is throughout the whole medical education, including three themes of statistics and epidemiology related knowledge, health related issues and professional development. The varied teaching modes are combined with electronic teaching equipment and students' subjectivity in learning is emphasized. Drawing insights from the medical education in Canada, we should focus on promoting early contact and lifelong study of medical humanities curriculum for medical students, enriching the curriculum content, enhancing the curriculum practicality, diversifying the teaching methods, strengthening the teachers' training, improving the assessment system and establishing the long-term mechanism.

Résumé
Objective: To investigate whether there are differences of palliative care of advanced cancer pa-tients' life quality between the medical institutions care mode and home care mode and the causes. Methods:Col-lecting eligible advanced cancer patients in the palliative care wards of community health service center and in the home palliative care unit in a year and a half, among which 53 patients were in the ward and 60 patients were at home. Evaluations for life quality were conducted before palliative care and after 2 weeks of palliative care. Re-sults:There were no differences before and after the intervention at palliative care wards in the aspect of role func-tion among patients ( P >0 . 05 ) , while there were improvements in all dimensions of life quality ( P <0 . 01 ) . There were improvements in all dimensions of life quality among patients at home ( P<0 . 01 ) . Other aspects were statistically significant (P<0. 01) except body functions, emotion functions, and somnipathy (P>0. 05) by com-paring the differences of the two groups. Patients at home had better role functions, social functions and less nausea and vomiting than patients at wards, and economic impact was bigger than that at wards(P<0. 01). Patients at wards had better conditions in recognition functions, general life quality, fatigue, pain, expiratory dyspnea, appe-tite loss, constipation and diarrhea than that at home(P<0. 01). Conclusion: Palliative care in either wards or home also can improve the life quality, and relieve symptoms and economic burdens.
Résumé
Objective: To evaluate the surgView-RFT electromagnetic navigation system in radiofrequency thermocoagulation(RFT). Methods: 6 foramen ovales of 3 cadavers were punctured by 3 beginners. Every one tried 5 times by free-hand and 5 times by SurgView-RFT electromagnetic navigation-guidance. After each puncture, CT scans were used as golden standard to measure the distance between the tip of needle and the anterior margin of the foramen ovale. T test and variance of SAS 6.12 statistical software was used to do the statistic analysis. Results: The punctures by free-hand failed, and the distances between the tip of needle and the anterior margin of the foramen ovale were 8-10.6 mm. The punctures by navigation guidance were successful, and the distances between the tip of needle and the anterior margin of the foramen ovale were 2.68-3.54 mm. The error of navigation system was 0.59 mm which was verified by CT scan. There was significant difference between free-hand puncture and navigation-guided puncture. Conclusion: The surgView-RFT electromagnetic navigation system is characteristic with high performance, high accuracy and minimal invasion, while it is applied in training or clinical using.
Résumé
Objective:To study the effect of IL-15 eukaryotic expression plasmid on the humoral immune responses to HBV surface antigen protein vaccine.Methods:Had constructed two of IL-15 eukaryotic expression plasmides.One is the eukaryotic expression plasmid of the IL-15 whole sequence,the other is the chimeric eukaryotic expression plasmid of the IL-2 signal peptide and IL-15 mature peptide sequence(IL-2s-15).The bioactivities of the expression products of the two plasmids were identified by CTLL-2 proliferation assay.Results:After IL-15 plasmid co-immunized with HBsAg,the titer of anti-HBsIgG was much higher than that of control( P 0.05),however,the anti-HBsIgG2a/IgG1 ratio was higher than that of control.Conclusion:IL-15 expression plasmids effect differently on the immune responses induced by protein vaccine.
