8.Construct an Innovation-Oriented Campus Culture and Strengthen the Career Starting Concept among College Students
Chinese Medical Ethics 1995;0(03):-
Embodied as an abstract concept as well as concrete regulations and material environment on the campus,the campus culture is the organizational culture among universities,which plays a significant role in enhancing students' quality of career starting.Similar to its social culture,the American campus culture is characterized by a strong personal heroism thus is known as a "cowboy culture".As the so-called "dragon culture",the Chinese culture is a more conservative one and thus lack of innovation-oriented career starting concepts among Chinese university students.Therefore,in order to effectively carry out entrepreneurship education in colleges and universities,the innovation-oriented campus culture should be constructed,students' entrepreneurship conception strengthened,thus students' sense of career starting and mental status be enhanced.
9.Causes analysis and handling of postoperative complications of femoral shaft fracture treated with intramedullary interlocking nails
Chinese Journal of Trauma 2001;17(5):290-292
Objective To investigate the causes and preventive methods of postoperative complications of femoral shaft fracture treated with intramedullary interlocking nails. Methods A total of 116 patients with femoral shaft fractures admitted to our hospital from 1994 to 1999 were retrospectively studied in this article. They were all treated with intramedullary interlocking nails. The locking nails were removed from the 14 patients with delayed union to convert the fixation from static to dynamic. For the 6 patients with bone nonunion, the locking nails were removed, and new locking nails and bone grafts were employed. And for the 4 patients with bone infection, the foci were cleaned and the locking nails were removed, then certain external fixation was applied. Results Followed up for 1 year, the fractures of 14 patients with delayed union were completely healed. For the 6 patients with bone nonunion, reoperation was needed in 4 patients and a third operation needed in 2 patients, and they all healed after being followed up for one and half a year. For the 4 patients with bone infection, only 3 patients healed. The whole effective rate was 95.8%. Conclusions Although the intramedullary interlocking nails used for femoral shaft fractures have advantages than other internal fixations, the complications of delayed healing, nonunion, bone infection and breaking nails are often found. The effective measures to reduce the complications include strict master of the operative indications, suitable materials for the implant and conversion of the fixation from static to dynamic in time, careful selection of debriding the realm or debriding no realm, complete debridement and strict abacterial procedures.
10.Chronergy of umbilical cord blood-mesenchymal stem cell transplantation for treatment of hypoxic-ischemic brain damage
Chinese Journal of Tissue Engineering Research 2008;12(25):4975-4978
BACKGROUND: Mesenchymal stem cell transplantation for treatment of hypoxic-ischemic brain damage (HIBD) has obtained some outcomes in adult animals, but studies are few in neonatal animal models. Mesenchymal stem cells are commonly harvested from bone marrow. A few studies are on umbilical cord blood-mesenchymal stem cells (UCB-MSCs). OBJECTIVE: To investigate the feasibility and timeliness of UCB-MSC transplantation after injecting UCB-MSCs into neonatal rat models of HIBD. DESIGN, TIME AND SETTING: The complete randomized controlled animal experiment was performed at the Laboratory of Department of Neurology of First Hospital Affiliated to Nanchang University from October 2004 to July 2005. MATERIALS: A total of 38 healthy neonatal SD rats aged 7 days old were used to create rat models of HIBD. Three rats died. METHODS: Cord blood samples were collected after normal full-term delivery of 23-35 healthy pregnant women for culturing UCB-MSCs. MSCs were labeled with 4',6-diamidino-2-phenylindole 2hci (DAPI) in vitro before transplantation. Thirty-five rat models were divided into three groups. UCB-MSCs were injected into tail vein of twelve rat models in the early transplantation group two days after modeling. UCB-MSCs were injected into tail vein of twelve rat models in the late transplantation group one week after modeling. Same volume of saline was injected into eleven rats of the control group. Six rats from early transplantation and late transplantation groups each were respectively obtained at day 2 after transplantation and at week 2 after modeling. Three, four and four rats from control group were obtained respectively 2 days, 1 and 2 weeks after modeling, and sacrificed after anaesthesia. Ischemic brain tissues from the brain and hippocampal gyrum were sliced into frozen sections. MAIN OUTCOME MEASURES: Brain tissue pathomorphology was measured by Haematoxylin and Eosin Staining. Brain tissue DAPI-positive cells were detected with a fluorescence microscope. RESULTS: Brain edema at ischemic region, neural cell swelling and a decrease in cell number were tested in the control group. DAPI-positive UCB-MSCs were few in focal brain tissues, and swelling degree,extracellular space improvement and increased cell number were insignificant in the early transplantation group. One week after modeling, brain tissue extracellular space became small, cell number increased, and brain swelling reduced; A mass of DAPI-positive cells in rat focal brain migrated and diffused, without significant boundary in the late transplantation group. CONCLUSION: UCB-MSCs effectively traverse blood-brain barrier, and migrate, disperse and conform around focal brain tissues. A good outcome of transplantation is obtained at week 1 after HIBD.
