The medical students are the future medical talent,so they need medical ethics education.This thesis lists medical students' cognitive bias on medical ethics study and enlightens some effective measures on it to achieve the educational purpose.

Chemotherapy and correlated treatments for primary bepatocarcinoma make great progress in recent years. Further studies for transarterial chemoembolization are investigating the new available embolization agents and drug eluting beads to improve the effect on tumor necrosis. Percotaneous ethanol injection for small hepatocellular carcinoma may be regarded as first line treatment. Hepatic arterial infusion and systemic chemo-therapy should also be considered further study.

ObjectiveTo explore the expressions of EGFR and Ki-67 in vulvar dystrophy and their clinical significance MethodsTissue specimens were collected from 160 patients with vulvar dystrophy.Immunohistochemical method was used to detect the expressions of EGFR and Ki-67 in these specimens.The expression levels of EGFR and Ki-67 were compared among different pathological subtypes of vulvar dystrophy,and the relationship of these expressions with clinical pathological characteristics was assessed.ResultsNo significant differences were observed in the expressions of EGFR or Ki-67 between vulvar dystrophy of squamous cell hyperplasia type,lichen sclerosus type and mixed type(P ＞ 0.05).The expression level of EGFR was positively correlated with that of Ki-67 in vulvar dystrophy (r =0.66,P ＜ 0.05).There was a significant difference in the expression rate of EGFR and Ki-67 between patients with different courses of vulvar dystrophy(both P ＜0.05),but not between patients with different age at onset of vulvar dystrophy(both P ＞ 0.05).Conclusion The expressions of EGFR and Ki-67 are different among patients with different courses of vulvar dystrophy.

The paper analyses the function of mutual communication in solving physician-patient conflict. Some feasible suggestions on the mutual communication between doctors and patients are also raised in order to solve the physician-patient conflict effectively.

Objective To establish the quality standard of Huangqi-Changyu'an capsule. Method Thin layer chromatography was used to identify psoralen, evodia mtaecarpa, and nutmeg in Huangqi-changyu'an capsule. HPLC was used to determine the content of psoralen. A Hypeisil BDS C18 column(200 mm×4.6 mm,5 μm) was used with mobile phase consisted of acetonitrile-water (30:70) at the rate of 1 ml/min. The detection wavelength was set at 245nm with the column at room temperature. Results The liner range of psoralen was 3.572~53.58 μg/ml (r=0.999 9) with average recoveries of 99.04%, and the RSD was 0.8%. The liner range of isopsoralen was 3.796~56.94 μg/ml (r=0.999 9) with average recoveries of 99.20%, and the RSD was 0.6%. Conclusion This method is sentivive, accurate and rapid for the quality control of Huangqi-Changyu'an capsule.

Objective To explore the influence of vacuum sealing drainage(VSD) technology in snake bite treatment.Methods 108 patients of snake bites need to incision decompression were randomly divided into two groups,VSD group (VSD) 58 cases,conventional group (wound change dressings ordinarily) 50 cases.The secondary suture of time,the number of change dressings,material consumption fees,antibiotics use cost,wound infection rate,in hospital,average length of hospital stay were compared between two groups.Results Compared the VSD group with the conventional group,the secondary suture of time (t =11.743,P ＜ 0.05),the number of change dressings (t =50.661,P ＜ 0.05),material consumption fees (t =9.054,P ＜ 0.05),antibiotics use cost (t =21.515,P ＜ 0.05),wound infection rate (x2 =9.155,P ＜ 0.05),in hospital,average length of hospital stay (t =10.350,P ＜ 0.05) had significant differences.Conclusion VSD technique can be a ideal way to treat snake bites patients and worth popularizing at this stage.

OBJECTIVE To explore uticozation of nursing care in the operating room disinfection and isolation management. METHODS The nurses and doctors operating room were selected as the observers. Obsening in the operating room for 30-60 min, and recorded the results. After the guidance of the staff discussed to address the problem. RESULTS From June 2006 to June 2008, observed in disinfection and isolation problems of operating room management. The measures include 45 long-term plan, measures need to improve the implementation. To continue to reduce the existing problems, the increasing outstanding operation; Operating room working environment, surgical sterilization materials, sterile technique quality control inspection pass rate in 2006 from the third quarter of 94.2%, 97.1%, 95.1% to 2008 second quarter of 100.0%, 100.0%, 99.8%. CONCLUSIONS The meause can improve the initiative to participate in the management increase the communication between the department and surgery, disinfection and isolation technology improve the quality of management effectiveness. Disinfection and isolation of the operating room are needed to ensure the effectiveness of management to prevent nosocomial infection.

This paper introduces a new perspective of case choice in medical ethics teaching,which breaks through the limitations of the choice of teaching cases,chooses the hot-case analogy teaching methods out of medical field,and proves to have received good teaching results.

BACKGROUND:Intervertebral disc degeneration is the pathological basis of degenerative spinal diseases. Studies on the influentialfactors of intervertebral disc degeneration contribute to the prevention and treatment of degenerative spinal disease.
OBJECTIVE:To observe the growth and proliferation of nucleus pulposus cels isolated by trypsin plus type II colagenase digestion in complete medium with different glucose concentrations, exploring the optimal glucose concentration for growth of nucleus pulposus cels.
METHODS:Nucleus pulposus cels isolated and cultured by trypsin plus type II colagenase digestion method were observed under an inverted microscope, and thecelnumber was counted. Morphology of nucleus pulposus cels was observed afterhematoxylin-eosinstaining and toluidine blue staining. Colagen type II immunoreactivity was detected by immunohistochemical staining combined with immunofluorescent staining.Nucleus pulposuscels were incubated in complete medium containing various glucose concentrations (0, 6.25, 12.5, 17.5, and 25 mmol/L) for 24 hours, and then cel proliferation and apoptosis were determined.
RESULTS AND CONCLUSION:The stained nucleus pulposus cels showed polygonal and short spindle, with one or two nuclei. Celularpseudopod appeared gradualy and then became slim with increased passage numbers. The isolated and cultured nucleus pulposus cels positively expressed colagen type II and aggrecanProliferative activity of nucleus pulposus cels cultured in medium with 17.5 mmol/L glucose was significantly higher than that in medium with 0 and 25 mmol/L glucose (P< 0.05 orP< 0.01). There wasno significant differencein cel apoptosis between these groups except for 0 mmol/L glucose (P<0.05). These results confirm that a large number of nucleus pulposus celscan beharvested by trypsin plustype II colagenase digestion and the optimal glucose concentration is 17.5 mmol/L.

The basic nature of medical ethics education is the cultivation of morality for medical students,in which humanistic spirit is the fundamental element.Humanistic spirit is in great need for the development of medical ethics,the transformation of medical mode,the harmonious development of physician-patient relationship,and the healthy growth of medical students.Based on present realistic conditions,humanistic spirit should be developed in the fields of classroom training,medical professional education,and other aspects of campus culture.It would be necessary to find multi-path training modes of humanistic spirit.
