ABSTRACT
Aiming at the teaching characteristics of Medical Organic Chemistry in medical colleges and universities and the learning features of students, this article takes information technology as the medium and fully integrates autonomous learning mode of "teaching" and "learning" into the teaching process. In the teaching of Medical Organic Chemistry for students in grade 2017of Air Force Medical University, we adopted flipped classroom that is autonomous learning based on information resources-, student-centered micro-class assisted teaching, and self-learning mode such as self-designed experimental teaching based on network. The comprehensive scores of students of grade 2017 were compared with those of students of grade 2016 who adopted traditional teaching mode. The results showed that this mode of "teaching" and "learning" combined with "dominant-subject" can fully mobilize students' learning enthusiasm and initiative in Medical Organic Chemistry. It is more conducive for students to mastering learning methods, integrating knowledge and improving their ability to analyze and solve practical problems. The application of autonomous "teaching" and "learning" mode has effectively addressed the problems of insufficient interest of medical students in chemistry learning and problems of only one teaching mode for them. To a certain extent, it improves the quality and efficiency of Medical Organic Chemistry teaching.
ABSTRACT
@#ObjectiveTo observe clinical results and histopathological changes of scleral defect repaired with acellular xenogenic dermal matrix (Xeno-ADM) in rabbits.MethodsModel of rabbit sclera defect was established, and repaired with Xeno-ADM. The rabbits were clinically examined for inflammation and eyeball healing. The animals were sacrificed at 2nd and 4th week after operation, and implants were obtained and examined histopathologyically and ultrastructully with light microscopies respectively to evaluating changes of inflammation and vascularization.ResultsThere were no obvious inflammation and eyeball deformation observed. 2 weeks after implantation, the partial inflammatory cell invasion was seen with the light microscopy, and there was an obvious borderline between the Xeno-ADM and the sclera. 4 weeks after implantation, the inflammatory cells were reduced noticeably, the Xeno-ADM and the sclera completely merged with each other.ConclusionThe acellular xenogenic dermal matrix may be an ideal materix with fast neovascularization and low immunity for replace of sclera implants.
