Three Modules and Three Stages proposed by guidelines on college English teaching that will be issued by the Ministry of Education gives direction for college English teaching.Through the investigation of the students' cognition and learning of English curriculum,combined with the teaching experiment,the new system of English curriculum,which reflects the characteristics of medical colleges and universities,has been preliminarily established,aiming at cultivating medical students' comprehensive English abilities in medical study and career development.Considering students' language abilities in different stages,college English curriculum can be designed in three modules,that is,English for general purpose (EGP),English for academic purpose (EAP) and intercultural communication,in three stages,that is,the basic stage,the improvement stage,and the development stage.The practice shows that the new curriculum system can promote the interaction,reform and development of teachers,teaching teams and Foreign Language Department.

Objective To explore the feasibility of mouse muscle-derived cells with adenovirus-mediated expression of BMP-2 in the treatment of mouse tibia bone defect via collagen sponge as scaffold. Methods Mouse adenovirus BMP-2 plasmids were prepared and identified by PCR.The adherent cells of muscle-derived stem cells cultured in vitro were passaged,cells of the third generation were selected,and recombinant Ad-BMP-2 plasmids were expressed and incubated in mouse myoblasts.The number of BMP-2 positive cells was measured using indirect immunofluorescence method,and alkaline phosphatase(ALP) method was adopted to determine the cell activity in each group.The mouse models of proximal tibial bone defect were established(n=80) and were divided into Ad-BMP-2 transfection group,Ad-LacZ transfection group,blank group and Ad-BMP-2 implantation group.The histological and radiological changes were observed 3 weeks after operation. Results It was revealed by indirect immunofluorescence that BMP-2 positive cells were frequently found in Ad-BMP-2 transfection group,while none were observed in Ad-LacZ transfection group and blank group.The ALP activity was higher in Ad-BMP-2 transfection group,while that was extremely low in Ad-LacZ transfection group and blank group.There was most typical imaging of repair and healing of bone defect in Ad-BMP-2 transfection group,followed by Ad-BMP-2 implantation group,while there was no typical imaging in Ad-LacZ transfection group and blank group. Conclusion The constructed Ad-BMP-2 plasmids can effectively transfect mouse muscle-derived cells,and the transfected cells can continuously express effective amount of BMP-2.The mouse muscle-derived cells with adenovirus-mediated expression of BMP-2 play a definite role in the treatment of bone defect,which provides an effective method and material for clinical application.

Objective To investigate the efficacy and safety of different strategy of antithrombotic therapy in elderly patients with atrial fibrillation (AF) and coronary disease.Methods 224 inpatients and outpatients with AF and coronary disease whose mean follow-up time was 2 years,were divided into warfarin group,warfarin combined with antiplatelet drug(aspirin or clopidogrel) group,antiplatelet drug(aspirin or clopidogrel) group and control group.The thromboembolic event rate and adverse events incidence were observed in different groups.Results The risk of thromboembolic events,particular emerging risk of cerebral infarction in the control group(12.50 ％) was significantly higher than other groups (P＜ 0.05).Thrombotic event rates in warfarin + single joint group(2.78％) was lower than other groups(warfarin group 4.29 ％,single joint group 5.81％),but there was no significant statistical difference.The overall risk of bleeding in the control group (3.13 ％) was significantly lower than other antithrombotic group (P＜0.05).The incidence of skin bruising in single joint group was lower than other antithrombotic groups,the overall bleeding risk,especially gasfrointestinal bleeding in warfarin+ single joint group was significantly higher than other groups (P＜ 0.05).Conclusion Elderly patients with coronary heart disease and atrial fibrillation need antithrombotic therapy to prevent thrombotic events.Using warfarin alone or warfarin combined antiplatelet drug does not lead to serious bleeding events,but generally bleeding risk should be attracted more attention.

Allergic rhinitis is nasal mucosa of immediate hypersensitivity, and the current treatment is not satisfied. With the increasing incidence in recent years, we pay more attention on the effective treatments. There are some published studies indicate the benefit of probiotic for allergic rhinitis. Refer to the related literature in recent years, the paper will discuss probiotic species, safety, route of administration, mechanism and efficacy, pointing out a new direction for the treatment of allergic rhinitis.

Objective To explore the effect of open storage and peeling on the fluorine content of dried com in order to provide a scientific basis for prevention and treatment of coal-combustion fluorosis. Methods In October 2006, 34 samples of freshly dried and 3-month old dried com were sampled in Zhenxiong county, Zhaotong city, Yunnan province. Fluorine content in corn was determined by combustion-hydrolysis-ion selective electrode method. Results The average fluorine content of freshly dried corn by coal-combustion was (4.29 ±1.87)mg/kg,and increased to (6.64±2.64)mg/kg after they had been openly stored for three months and the average content increased by 54.74%. But if corn was peeled off, their fluorine content decreased to (5.03±2.04)mg/kg at a rate of 24.25%. The amount of fluorine absorbed by the skin of corn was more than other parts of com during corn desiccation. Conclusions The inhabitants in coal-combustion fluorosis areas ingest less fluorine through dry com if they eat the peeled corn and take measures to keep it airtight and moisture-proof during storage thus reducing the harm of coal-combustion fluorosis.

Objective To summarize the management of cardiopulmonary bypass(CPB) for infants below 10 kilograms with congenital heart diseases.Methods From Jan 2010 to Apr 2011,the clinical datas of 122 infants aged from 1.5 months to 2 years with body weight 3 to 10 kilograms,who underwent open heart surgery under mild or moderate hypothermia CPB were retrospectively analyzed.Results Among all the 122 infants,CPB time was 13 ～ 118 min [(62.69 ± 21.48) min],aortic cross-clamp time was 0 to 86 min [(35.47 ± 19.51) min].All patients were spontaneous resuscitation and successfully weared from the machine,no severe complications associated with CPB occurred,3 infants died (2.46％,3/122) after operation.Conclusion Using membrane oxygenator,circuit tubing and artery filter with less priming,and highflow perfusion during CPB,maintaining hemodynamics stable,holding reasonable hematocrit and colloid osmotic pressure,good myocardial protection and ultrafiltration are the significant elements of the management of CPB in infants with weight less than 10 kilograms.

In order to suit the trend of integration and development of modem medical disciplines and the reform trend of integration of curriculum system, the Third Military Medical University attempts to build a new curriculum system for medical postgraduates. The new system reveals the accuracy towards the teaching objects, the integration of curriculum structure, the update of the teaching contents and the diversity of the teaching methods. Besides, it combines the reform of teaching management, which will push forward the cultivation quality of the medical postgraduates.

Oncomodulin (OM) is known by us progressively as a Calcium binding protein.Recently, OM has been found that it is secreted by inflammatory cells (neutrophilic granulocyte), and a signal which can promote cell growth between innate immunity and neurons, and a key to regenerate the damaged optical nerves by activating inflammation.The function of promoting the regeneration progress of axons has become a hot issue in recent years.This article summarized the mechanism of OM and the relationship between inflammation-induced OM and optic nerve regeneration research and progress were reviewed.
