Résumé
Proteomics is an emerging discipline and has been widely used in a variety of fields despite of having very short history in comparison with other disciplines. In Chongqing Medical Univer-sity, the course contents were adjusted to fulfill the most effective integration of proteomics research with postgraduate training program for medical university. Diverse teaching was advocated here and af-ter-school communications were greatly encouraged in teaching. Traditional multimedia teaching plat-form remained the main teaching way and students were organized to visit the research platform as supplementing teaching way. The overall quality and effectiveness of teaching were effectively improved by successful implementation of the above initiatives.
Résumé
Teachers introduced the means of the scientific thinking and scientific research prac-tice in the curriculum of proteomics in order to train the postgraduates to joint the theory and the practical research work in the curriculum course. For example, to cultivate students to truly understand the 2-DE protein separation technique, teachers used the various proteomic profile obtained from our research to points out its problems and limitations based on the classical 2-DE, then compared the improved 2-DE protein separation chromatography with the classical 2-DE graphic and analyzed what is the problem and how to solve them in the practical work. To improve the ability of scientific thinking for postgraduates , teachers took the tumor as the teaching cases and asked the postgraduates to search the references of can-cer associated with their professional , to put forward the scientific problems based on carefully reading these references, to design their research project and to seek the answer to their issue. These new teaching methods were found to be beneficial in training scientific talents of medical postgraduates.
Résumé
Tumor microenvironment has been confirmed to play an important role in the occurrence, invasion and metastasis of many kinds of tumors. Carcinoma-associated fibroblasts (CAFs) are the primary type of host cells in the tumor microenvironment. CAFs have an assignable role in tumor development. CAFs create a suitable "soil" for tumor origination, secrete a large amount of growth factors promoting tumor growth and angiogenic factors promoting tumor angiogenesis. In addition, CAFs attract a large number of inflammatory cytokines, and secrete a great quantity of soluble products promoting tumor cell invasion and metastasis. Therefore, CAFs may become new targets for targeted cancer therapy, and provide new ideas for the clinical cancer comprehensive treatment.
