RESUMO
Current reform of higher medical education focuses on curriculum integration and corresponding reconstruction of teaching system. Chongqing Medical University has carried out the reform of medical personnel training mode from basic to clinical, which has achieved certain results. Three aspects including teaching content, teaching methods and appraisal system of the urogenital system curriculum integration are introduced in the paper. In the teaching content, the parts related to urogenital system in basic subjects and clinical subjects are extracted and integrated. In the process of teaching implementation, a teaching team is set up across departments and multidisciplinary joint teaching is carried out. In order to arouse the enthusiasm of students, inspire and cultivate students' scientific research thinking by improving teaching methods, several teaching methods such as case introduction teaching method, question discussion and debate meeting are used. Scientific evaluation system is used to observe and record the whole process of students' learning. Meanwhile, some existing problems and solutions of curriculum integration are discussed in the paper to provide references for peers in relevant colleges and universities.
RESUMO
Objective: To study the chemical structure of polysaccharide CDP 4 isolated from Cistanche deserticola Y.C.Ma. Methods: The chemical properties of CDP 4 were determined by using chemical method and spectrocospic method. Results: CDP 4 was composed of glucosyl group, with the ratio 1,4 linkage glc p ∶1,6 linkage glc p =3∶1,and its mean molecular weight 1.4 ?10 4. By means of methlylation analysis, complete acid hydrolysis analysis, NMR spectrum, the linkages and sequence information of CDP 4 were obtained. Conclusion: CDP 4 is a new linear glucan.
