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.

This article summarizes our experience in nursing 40 gastric carcinoma patients receiving fast track(rapid recovery) surgery,proposing that the emphasis of nursing should be placed on psychological care and health education before the operation,warm-keeping during the operation,pain control,early food intake,early movement and management of complications after the operation,and necessary follow-up after discharge.

The right ventricle owns a complex geometry chamber and a special anatomical structure , which makes it dif-ficult to precisely assess its function .Right ventricular function has been found to be important in the development of cardi -ovascular diseases .This review summarizes recent progress in the characteristics and elevation of right heart function .

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 establish a method for content determination of bavachin and bakuchiol in Psoralea corylifolia.METHODS:HPLC method was adopted.The determination was performed on Shim-Pack VP-ODS column with mobile phase consisted of acetonitrile-water (gradient elution) at the flow rate of 1.0 mL/min.The detection wavelength was set at 246 nm,the column temperature was 30 ℃,and the sample size was 10 μL.RESULTS:The linear ranges of bavachin and bakuchiol were 48.9-489 ng(r=0.999 8),784-7 840 ng(r=0.999 9).RSDs of precision,stability and reproducibility tests were all lower than 2.0％.Average recoveries ranged 95.30％-99.63％ (RSD=1.45％,n=9),96.89％-100.82％ (RSD=1.36％,n=9).CONCLUSIONS:The method is simple,accurate,stable and reproducible,and can be used for the simultaneous determination of bavachin and bakuchiol in P corylifolia.

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.

Objective To investigate the regularity of changes an d the base line of physiological deficiency of ventricular diastolic function in normal individuals. Methods Non-invasive echocardiography was employed for monitoring hemodynamics of the ventricular diastolic function in n ormal individuals. 240 volunteers were divided into four groups by age, i.e. juv enile, youth, middle-aged and elderly groups. Items of examination included the diameter of cardiac chambers by two-dimensional (2D) echogram, velocity of dia stole of ventricular wall by M mode, velocity and ratio of blood flow at left an d right atrio-ventricular valves and pulmonary vein by spectral Doppler, fillin g phase and duration of filling of ventricles in diastolic phase by color Dopple r. Results Of mitral valve, tricuspid valve and pulmonary vein, a series of dynamic parameters of blood flow were correlated closely with the a ge. The ventricular diastolic function of normal person deteriorated physiologic ally with the passage of years, characterized by a normal stage in juvenile and young ages, compliant decreased stage in middle-age, and declined functional st age in aged. The declination course started in the left ventricle prior to the r ightventaide. Conclusion The results of the present study may b e helpful for further clinical researches on the mechanisms of changes in human ventricular diastolic function.
