In clinical teaching we should not only train the students in scientific clinical thinking manner and inform them of recent progress of cardiovascular system,but also cultivate their information quality,improve their ability of applying medical English and enhance their consciousness of medical disputes prevention.

Objective To study the treatment of pancreatic injury accompanied with nervous injury. Methods 22 patients were divided into three groups. They were treated with different method and comparable in the duration of hospital stay, the time of nervous function recovery to normal,placement time of catheterization tube, complications and change of sera albumin.Results The duration of hospital stay were significantly shortened in combined therapy group patients than in control group. Combined therapy can promote recover of nervous function, reduce time to conserve catheterization tube. Reduce complications of pancreatic injury with accompanied nervous injury by combined treatment with somatostatin and growth hormone, it also can increase protein synthesis, correct hypoalbuminemia and reduce complication.Conclusions In combination of somatostatin and growth hormone early used to treat pancreatic trauma accompanied with nerves injure has valuable to heal pancreatic injure and recover the nervous function.

Objective To explore the influential factors of hospital management teaching and to apply new plans to improve quality of teaching. Methods Questionnaire survey was conducted among 94 students majored in health management in Xuzhou Medical College to investigate student' learning behavior as well as contents, applying value, procedures, and teaching effects of the course. Data was put in by Epidata 3.02, described and analyzed by SPSS 18.0. Continous variables were ana-lyzed by t test and classified variables were analyzed by X2 test. Results 25.6%(24/94) students were not interested in this course. 61.7%(58/94) students thought that the course was highly correlated with profession. 56.4%(53/94) students thought that the course was valuable. 35.1%(33/94) students thought that the course was not good in combining theory with practice in teaching. 19.1%(18/94) stu-dents thought that the course was deficient in interactive teaching and teaching methods. 62.8%(59/94) students were satisfied with the teaching effect. Conclusions Main influential factors of hospital man-agement teaching are learning interest, curriculum evaluation and teaching evaluation. To improve quality of hospital management teaching, it is necessary to communicate the importance of the course and to apply new teaching plans to arouse the interests of students.

Objective:To observe the effect of “One Coat Bond” on the interface between amalgam restoration and cavity wall used in bonded amalgam restoration(BAR).Methods:Dentin cavities were made on 15 healthy human premolars extracted for orthodontics therapy.The teeth were divided into 3 groups with 5 in each group.In group A compressive air was used to dry the cavities(dry adhesion) whereas in group B absorbent cotton was used (wet adhesion). Then the cavity walls in the two groups were treated with the “One Coat Bond”, the cavities were filled with freshly prepared amalgam before adhesive concrete.In group C cavities were filled directly with amalgam without treatment of cavity walls. Morphology of amalgam restoration/“One Coat Bond” adhesive/dentin cavity wall interface was observed under SEM, thickness of adhesive and width of space between amalgam restoration and cavity wall was measured. Results:Average width(?m) of space between restoration and cavity wall was 4.82 in group A, 0 in group B and 11.33 in group C(P0.05).Conclusion:“One Coat Bond” adhesive can significantly improve the compactness between amalgam and cavity wall.

International experiences can provide evidences for general practitioners ( GPs) system building in China. The paper reviews the development of GP systems from several typical countries of different insurance sys-tems, including national health care systems, commercial medical insurance systems, and social medical insurance systems, etc. The factors that influence GPs systems are analyzed. It is found that the control force of health security system on health system, the control force of specialists on health system, the incentive mechanism of general prac-tice, and the development of general medicine influence the establishment of GPs systems. Finally, this paper pro-vide several policy implications:First, in order to meet the needs of public health, a GPs system with Chinese char-acteristics should be established;Second, the core values of general medicine should be promoted to provide public support for the establishment of a GPs system;Third, a sound incentive mechanism should be established for the de-velopment of a GPs system to improve the status of general practitioners;Fourth, the division of general practitioners and specialists should be promoted to improve the development of general medicine.

ObjectiveTo investigate the influence of r egional wall motion abnormality(RWMA) on cardiac anatomic structure with coronary artery disease (CAD) and to recognize serious degree of the disease by echocardiography. MethodsA total of 125 cases was observed. There were 63 patients in CAD group (41 cases with general CAD,7 cases with acute myocardial infarction and 15 cases with old myocardial infarction). All the patients had undergone respectively CABG,PTCA and stent,coronary angiography or radionuclide scan for confirmation. There were 62 cases in normal control group. Using 2D echocardiography,stand short and long axis images of left ventricle(LV) were chosen. Displayed RWMA to compose the centripetal disharmonized motion with whole-wall of LV,and the discentripetal contradiction motion. M mode for continuous scan was to detect the typical characterisitic of RWMA. ResultsSingle-occurring RWMA from 43 cases ( 68.2 %) in 63 cases with CAD was displayed, while multiple-occurring RWMA from another 20 cases ( 31.8 %) was displayed(P

0.99. The recovery rates were 72.25% -109.0% with the relative standard deviation (RSD) of 1.82% -11.61% . Conclusion The method is fast,simple,sensitive and needs no organic solvent and it is applicable to the determination of organochlorine pesticides and chlorobenzene compounds in water.

Objective To study the effect of endothelial progenitor cells mobilization on vascular endothelial repair after carotid artery injury in rats.Methods The rat balloon-injured carotid model was established.In the control group:saline was administrated intragastrically;the simvastatin group:simvastatin 10 mg/(kg?d)was administrated intragastrically and in the simvastatin+ granulocyte colony stimulating factor(G-CSF)group:G-CSF 100 ?g/(kg?d)was intraperitoneally injected togother with intragastrical simvastatin from 1 week before operation to 2 weeks after operation.The repair rate of injuried endothelium,neointima/media area ratio(IA/MA),the positive cell index of proliferating cell nuclear antigen(PCNA)and nitric oxide(NO)release in peripheral blood were detected.In addition,the ratio of CD34+VEGFR2+ double positive expression cell was detected by fluorescence activated cell sorter(FACS),which indicated the level of EPCs.Results The repair rate of injured endothelium was increased(12.3%)in the simvastatin group compared with the control group;IA/MA was reduced 18.4%;NO release was increased 33.9% and the positive cell index of PCNA was reduced 5.7%.These data were 38.2%,50.3%,33.9% and 37.2% respectively in simvastatin+G-CSF group.Compared with the control group,the ratio of CD34+VEGFR2+ double positive expression cell was increased 87.6% in peripheral blood,and it increasd 343.4% in simvastatin+G-CSF group.Conclusion The results suggest the possibility that simvastatin may promote the EPCs from bone marrow to peripheral blood,so it can improve the effect of repair rate of injured endothelium and inhibit neointimal hyperplasia.In addition,G-CSF can enhance the effect of simvastatin on the injured endothelium and neointima hyperplasia.

Objective To investigate the feasibility of endothelial reconstruction in the injuried arterial wall by autologous endothelial cells transplantation. Methods New Zealand white rabbits (n=20) were subjected to bilateral iliofemoral artery balloon injury, Cultured autologous venous endothelial cells were immediately transplanted by balloon catheter into one vessel, whereas the contralateral artery received the medium only. In 10 rabbits, vessels were harvested 4 hours and 4 days after transplantation for analysis of endothelial coverage by scanning electron microscope (SEM); In 5 rabbits, the cultured endothelial cells were labeled with a fluorescent tracer before their introduction into the injured vessel, and 4 days after transplantation, vessels were harvested to obtain fluorescent imaging of the seeded endothelial cells; Another 5 rabbits were sacrificed 4 days after transplantation for Evans blue staining. Results Four hours after the operation, SEM demostrated that the endothelial layer in control vessels were denuded completely, whereas some round endothelial cells had adhered into the aterial wall in cell transplantation group; four days after cell transplantation, the transplanted cells had attached and spread in the injuried aterial wall by SEM, a number of fluorescent labeling endothelial cells were observed in the endothelial denuded aterial wall, the vessels that received the medium only were stained nearly completely by Evans blue, whereas in those vessels that received cell transplantation, about 60% area were not stained. Conclusion Autologus endothelial cells can be effectively transplanted into the injuried arterial wall by balloon catheter.
