我校资产管理网络化的初步实现

1背景随着国家对教育投入逐年增加,特别是近年来重大科研项目如211工程、985项目等大批经费用于设备添置,学校固定资产急剧膨胀。同时高校规模不断拓展,综合性高校拥有2个以上校区的情况非常普遍。在这种情况下沿用旧的单机管理模式,     

大鼠脂肪干细胞复合胶原-壳聚糖-硫酸软骨素三维支架构建组织工程软骨

Objective To evaluate the character of the collagen-chitosan-chondroitin sulfate scaffold seeded with rat adipose tissue-derived stromal cells. Methods A dipose tissue were harvested from 6 weeks old Wistar rats and the stromal cells were harvested by type Ⅰ collagenase and then cultured in vitro. Type Ⅰ collagen was fully mixed with chitosan, freeze-dried and cross-linked with chondroitin sulfate, then freeze-dried again and sterilized by ethylene oxide. The pore diameter, water content, porosity of the scaffold were tested. The adipose tissue-derived stromal cells were digested, seeded into the plates, scaffold, and cen-trifuged into pellet, and then induced into cartilage. MTT detection for cell proliferation was done. After 3 weeks, the cell morphology, and cell proliferation and adhesion were observed, and chondrngenic differenti-ation was also analyzed. Results The pore diameter, water content, porosity tested for the scaffold showed an appropriate form. Cell proliferation showed faster in the scaffold and pellet culture system after 5 day, there was still cell proliferation in the scaffold system after 14 days but no obvious changes in the pellet cul-ture system; ceils on the scaffold proliferated densely showed by histological staining, but there was a scaf-fold structure residues in the inner layer. The finding of type Ⅱ immunohistochemistry stain showed that cells express strong positive for type Ⅱ collagen in the scaffold and pellet culture system whereas it was weakly positive in the plate culture system; the specific mRNA for cartilage, type Ⅱ collagen, aggrecan and SOX-9 were expressed in all three systems showed by RT-PCR, but type X collagen was expressed continu-ously in the plate culture system and expressed after 21 days in the pellet culture system, whereas it was not detected in the collagen-chitosan-chondroitin sulfate scaffold system. Conclusion The parameters of the collagen-chitosan-chondroitin sulfate scaffold were suitable in our study. The results suggested that it can promote the adipose tissue-derived stromal cells proliferation and chondrogenic differentiation better than the plate and pellet culture systems and maintain the phenotype of chondrocytes well; it is the optimal choice for cartilage tissue engineering in the future.     

浅论医科院校生物医学工程专业人才的培养

生物医学工程是工程技术与医学相互结合、渗透和交叉的一门新兴边缘学科,它对现代医学的发展起着重要的作用。随着科学技术和现代医学的发展,对医学院校培养生物医学工程专业人才提出了较高要求。既要有扎实的工程技术基础,又要掌握基本的医学知识;既要有管理决策能力,又要有解决专业技术问题的能力;既要会使用和维修医疗仪器设备,又要医工结合搞有关科学研究。因此,医科院校如何培养生物医学工程专业人才,是生物医学工程专业教育值得探讨的问题。1培养复合通用型人才是生物医学工程专业教育的目标军队生物医学工程专业学生毕业后,除个别去…
