With the gradual transformation of the American medical model from biomedical medel to bio-psycho-social model,the advancement both in the medical security and service system,preventire medicine as well as the protection of environment have been emphasized,while the revolution of the medical education has been carried out according to the divemified requirements of the bio-psyeho-social model,and the focus of health care has been moved forward.

Medical science is both scientific and humanistic,and medical humanities education is an ever-lasting theme.To enhance residents'health,a new health service reform is being carried out by the government to promote the transformation towards the bio-psycho-social medical model.Social reality,mental environment and social factors have significant effects upon health.To impart medical humanities knowledge and cultivate quality of humanities are the missions of higher education.Based upon the practice of medical humanities education in Sun Yat-sen University and the experience of developed countries and regions,and by elaborating the theory to deepen understanding of medical humanities the author is to deal with the real needs and to enhance educational effectiveness of countermeasures.

The authors calculated the correlation coeffi. of the scores of 3+X entrance exam and the scores of coursesat university in medical students of clinical medicine, medical imaging, anesthesiology. We found that there were rela-tionship among the overall score and English score of 3+X entrance exam as well as the scores of most major coursesat university in medical students, and there were relationship among the scores of chemistry and physics at entranceexam as well as the scores of partial major courses in the beginning at university. The result also indicated that entranceexam had a good prediction.[

Medicine is a practicing and experiencing subject.The most important study method for medical students is to practice during clinic.With the development of society,patients' consciousness of sticking up for their rights is stronger and stronger.During their receiving medical treatment,they are not satisfied with the teaching behavior provided by physician,and even to make medical conflicts.To resolve these conflicts,it is necessary to rule the clinical practicing teaching,harmonize the relationship between clinical teachers,medical practicing students,and patients.Medical education should be based on humanity and should be behaved by law.

The author reviewed papers on Evaluation on Teaching Hospitals in China from 1997 to now.Teaching hospitals were evaluated by educational and health administrator of local government since 1997.The methods the roles of evaluation,advantage and disadvantage of evaluation on teaching hospitals were described in this paper.

Assessment or evaluation of student performance in a problem-based learning (PBL) curriculum is difficult to plan or implement.Many medical schools which have switched to a PBL learning format usually use traditional evaluation methods based on factual recalls, which usually has a negative influence on the learning style of the students, thereby reducing the impact of PBL. The purpose of this review is to discuss the various evaluation methods with a particular focus on methods applicable to PBL, so that we can make intelligent use of these methods in our PBL curriculum. In combination with evaluation methods adopted at McMaster University, the article makes an elaboration about them.

We selected scores for histology and embryology,physiology,biochemistry,pathobiology,pharmacology,paediatrics,and medicine of the first-year(2004),second-year(2003),third-year(2002)students at a medical school as subjects to analyze construction validity using factor analysis.The common factors were selected if their cumulative value above 60%.The result showed that variance percentage explained by each factor was lower,and that the three level structure formed by recall,comprehend and application would not be explained ideally by these scores.The author considered that the examination items should be improved and it was limited for factor analysis method to apply to analyze medical examination items.

The purpose of the present study was to investigate teacher-dominant action and focus on learning-oriented group.Medical teachers should pay more attention to three important aspects,such as optimizing teaching pattern,dealing with the relationship carefully among pre-class,inter-class and post-class.It is important to attach importance to pre-class,giving prominence to inter-class and also giving attention to post-class,which can form a harmonious,interactive and collaborate class.In addition,it stimulates deep processing interactions between teachers and students by increasing students learning interests,which is very helpful in improving teaching effects of medical image.

Objective To investigate the effect of the evaluation on teaching hospitals affiliat-ed to medical colleges in Guangdong province. Methods Questionnaire and on on-the-spot investi-gation was conducted among 18 teaching hospitals which owned the accreditation for 2-3 years based on Guangdong provincial teaching hospital accreditation indicator system 2008 modified version. Contents of investigation included general situation,teaching condition,management and implementa-tion of teaching activities as well as medical staffs' comments and suggestions for the teaching work. SPSS 13.0 software was used for frequency analysis. Results The general situation,teaching condi-tion,management and implementation of teaching activities were improved to varying degrees after the evaluation according to results of the questionnaire. 90.0%(54/90)people thought that the overall scale of the hospital was expanded and 5.0%(3/60)people thought that the overall scale of the hos-pital was obviously reduced or marinated the original level. 11.6%(7/60)and 88.3%(53/60)people thought that medical quality of the hospital was improved or obviously improved. 60.0%(36/60)people thought that educational occupancy of the hospital was improved while 5.0%(3/60)people thought that it was unsatisfactory. 83.3%(50/60)people thought that teaching mold and infrastructures were improved while 10.0%(6/60)people thought that it was unsatisfactory. 95.0%(57/60)people thought that teaching management was improved. Due to the lack of incentives and support in teaching work, management of teaching was loose. Conclusions The teaching work of t hospitals affiliated to medical colleges in Guangdong province do persevere basically and achieve desired purposes.

Background and purpose: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a new minimally invasive method in the dignosis for mediastinal lymph nodes. This study was to evaluate the diagnostic yield of EBUS-TBNA for mediastinal lymph nodes. Methods: Twenty patients with mediastinal lymph nodes found by CT underwent the dignosis by EBUS-TBNA form April 1st 2009 to July 16th 2009. The sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy of EBUS-TBNA were evaluated. Results: Twenty patients with 37 lymph node groups were studied. Overall sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy of EBUS-TBNA for diagnostic were 84.62%, 100%, 100%, 77.78% and 90.00%, respectively. The diagnostic accuracy for cancer was 100%. The operation time was 11.9min per group in average with no serious complication. The median length of hospital stay was 1 (range from 1 to 17 days) day after operation. There were significant differences in the average operation time between the first three patients and the others (36.25 min vs. 7.76 min; z=3.247, P=0.001). Conclusion: Endobronchial ultrasound-guided transbronchial needle aspiration proved to be a safe procedure with a high yield for the diagnosis of mediastinal lymph nodes.
