Fermentation engineering is an elective course for food science and engineering specialty. There are some problems in the teaching process, such as lagging teaching content, single teaching methods and means, backward assessment methods and so on. In view of these problems, this paper explored and practiced the teaching reform from the aspects of optimizing the teaching contents, improving the teaching methods and innovating the examination methods. This paper explored the ideological and political design and practice of fermentation engineering course teaching, so as to improve the teaching quality of fermentation engineering continuously, mobilize students' learning enthusiasm and practical level, and enhance the lifelong learning ability.

BACKGROUND: Whether one-stage bone healing with red bone marrow or mesenchymal stem cell transplantation is needed? Whether closed reduction with intramedullary interlocking nailing combined with autologous red bone marrow transplantation can promote osteogenesis in the one-stage treatment of femoral comminuted fracture still remains unclear. OBJECTIVE: To explore the effects of closed reduction with intramedullary interlocking nailing and one-stage treatment with autologous red bone marrow transplantation on fracture healing. METHODS: Twenty healthy New Zealand rabbits were selected and anesthetized, and then the models of femoral comminuted fracture were established at the hinder limbs after throwing a 5 kg of hammer from 30 cm height. All rabbits underwent intramedullary fixation using Kirschner wire (diameter: 2 mm); the right limbs served as control groups, and the left limbs as transplantation group, subjected to the injection of autologous red bone marrow (1 mL) into the fracture region. Then the rabbits were respectively killed at 14, and 28 days after modeling, the thickness of thickest callus was measured on X-ray films, and the number of chondrocytes and relative area of bone trabecula in the fracture region were observed through hematoxylin-eosin staining under light microscope. RESULTS AND CONCLUSION: (1) The thickness of callus formation in the control group was significantly less than that in the transplantation group at 14 days after modeling (P < 0.01). (2) The number of chondrocytes in the transplantation group was significantly more than that in the control group at 14 days after modeling (P < 0.01), and the fracture healing in the transplantation group was faster that in the control group. (3) Compared with the transplantation group, the relative area bone trabecula in the fracture region in the control group was significantly reduced at 28 days after modeling (P < 0.01). (4) These finding indicate that red bone marrow transplantation promotes fracture healing in the intramedullary fixation for femoral comminuted fracture in rabbits. [ABSTRACT FROM AUTHOR]
