Assurance system of Medical Quality is the core of teaching quality assurance work from colleges itself.This paper analysed the major factors affecting the teaching quality such as teachers,students,the teaching environment,teaching management based on quality management theory,making use of information technology to support the implementation of quality assurance system,constructing a system composed of five quality security system framework and forming protection of the quality of teaching based on information.

Objective:To determine the effect of standardized patients in medical international students' graduation practice assessment.Methods:The students were divided into two groups ofstandardized patient assessment and traditional assessment,the theoretical and professional performance was compared and analyzed after the assessments.All the students were investigated using questionnaire.Result:The students assessed using standardized patients reported higher skill scores than those with traditional assessments,and the difference was statistically significant.However,no difference was observed in theoretical scores.Gorcltusion:The introduction of standardized patient to medical international students' graduation practice assessment alleviates the status that emphasizes theory but ignores practice due to the lack of clinical resources,eliminates the obstacles in the communication between students and patients,and is conducive to the cultivation of humanistic quality and adaptability of the students.It is worthy popularizing in international students' graduation practice assessment.

Based on the background of knowledge economy,factors which have affected the social status of a person can be divided into five levels: physical fitness,technical ability,mental capacity,potential energy and recombination energy.This article analyzes the educational style of medical students by using five-level-ability model which judges a person from the economic angle.It aims at providing constructive opinions on innovation,enhancement and improvement of modern medical education.

Teaching diagnosis is also called analysis of the scene of teaching. By using multimedia teaching in the classroom,teaching monitoring system for remote video,the use of the basic method of Chinese medicine in the diagnosis of the disease"look,smell,ask and feel" to watch video playback,we let the students purposefully observe teachers’ teaching,conduct the "Self-or experts",feeling the pulse diagnosis,and find the inadequate teaching and make recommendations for improvement so as to ultimately enhance the quality of classroom teaching purposes.

Objective To investigate the position competency of residents in the first year and to search for the standardizing training which aims at advancing position competencies. Method Twenty residents of the first year and 40 of superior doctors were taken as research targets. Question-naires including 8 aspects (basic ability, occupational spirit, communication skills, medical knowl-edge, team work, public health, information and management, and academic research) were con-ducted and were scored namelessly. The scores of items in one kind of ability were summed up to serve as the total score of this ability. The mean score of one kind of ability and the mean score of 8 kinds of abilities of residents and superior doctors was calculated. SPSS 17.0 was adopted to make statistical analysis. t-test was adopted to test the difference between the score from residents and superior doctors with P<0.05 representing statistics significance. Results The scores of 8 kinds of abilities were much lower than full scores. The scores of basic ability, occupational spirit, and team work from residents (78.5, 87.4, 41.9) were higher than those from superior doctors (72.6, 80.5, 39.5), with statistical significances (P=0.020, 0.013, 0.045). Conclusions Residents are lack of position competency and awareness, which demonstrates the gap between the training model and the demand of work. It is sug-gested that we should design the training system and evaluation methods based on doctors' compe-tences, add training for comprehensive ability and evaluate abilities of all aspects. An excellent hu-manity education should be built and quality cultivation should be taken attention to. Objective and measurable indices should be developed to increase residents' knowledge.

The current status and training requirements for general practitioner (GP) were surveyed with questionnaires in 84 trainees from the first Beijing GP retraining program.Results showed that three most demanded skills of health service in community were electrocardiogram (98.8％),clinical lab results reading (96.4％),dressing change (90.5％).The services not provided but should be provided in community were aerosol rebreathing method (23.8％),resection of small superficial lumps (22.6％) and reading X-ray films (20.2％).The reasons for services not provided were insufficient resources (41.7％),lack of skilled personnel (35.7％) and staffing shortage (20.2％).The most required training skills were reading X-ray films (64.3％),electrocardiogram (54.8％) and laboratory results reading (51.2％).There were some skills inadequately trained including cricothyroid membrane puncture,suprapubic bladder puncture and resection of superficial small lumps.The results indicate that the required skills in community health service and individual demands of general practitioners should be the priority of the future training programs.

OBJECTIVEThis study investigated the effects of hydroxyapatite (HA)/chitosan (CS)-transforming growth factor-β1 (TGF-β1) composite coatings on titanium surfaces, as well as on the attachment and proliferation of osteoblasts.

METHODSHA/CS-TGF-β1 composite coatings were prepared on titanium surfaces by physical, chemical, and biological modifications. Scanning electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform-infrared spectroscopy (FTIR), and other methods were employed to analyze the chemical composition and surface topography of the composite coatings. CCK-8 and immunofluorescence assays were used to analyze the effects of the coatings on the attachment and proliferation of osteoblasts.

RESULTSHA/CS-TGF-β1 composite coatings were successfully prepared. Their contact angle was almost zero. These composite coatings were applied in vitro, with a drug released early and a burst release effect. The growth of osteoblasts was not inhibited on it and it had obvious promoting effect on the adhesion and early proliferation of osteoblasts.

CONCLUSIONThe composite coatings significantly promote the adhesion and early proliferation of osteoblasts in vitro. This finding shows that the proposed method demonstrates a good prospective application in surface modification of titanium.

A survey was conducted on a sample of 67 general practitioners ( GPs ) receiving in-service training in Beijing in 2012.Hypertension knowledge mastering and training status were investigated through a self-administered questionnaire .Results showed that the accuracy rates of the 4 domainitems (basic knowledge and skill, lifestyle modification, drug therapy, health management ) were 42.3%(340/804), 48.0%(225/469), 27.8%(96/335) and 70.6%(473/670), respectively with an overall accuracy rate of 49.8%(1 134/2 278).Trainees from urban scored higher than those from rural areas (P<0.01).About one third of trainees indicated that the 3 main teaching sessions they took part in did not cover the content of hypertension management .The hypertension guideline ( primary care version 2009) was most frequently used for training GPs , but only 33.9%(21/62) accessed such training .The results indicate that hypertension knowledge level seems to be generally low among GPs on in-service training in Beijing and the current training situation need to be further improved , particularly for those from rural areas .

OBJECTIVETo investigate the expression of PTEN and Caspase-3 in malignant lymphoma of the stomach and explore their role in progression of primary gastric malignant lymphoma.

METHODSFormalin-fixed paraffin embedded tissues from 56 cases of primary gastric malignant lymphoma and their adjacent non-tumor mucosa were evaluated for PTEN and Caspase-3 protein expression by streptavidin-biotin-complex (SABC) immunohistochemistry. Their expression was compared with clinical tumor parameters with the relationship between PTEN and Caspase-3 expression concerned as well.

RESULTSThe positive rate of PTEN expression in primary gastric lymphomas (50.0%, 28/56) was significantly lower than that in adjacent non-tumor gastric mucosa (96.4%, 27/28) (P < 0.05). Meanwhile, 43 of 56 (76.8%) gastric lymphomas indicated Caspase-3 expression, less than that in adjacent non-tumor mucosa (93.5%, 29/31) (P < 0.05). The expression of PTEN was negatively correlated with invasion and lymph node metastasis of gastric lymphoma (P < 0.05), while the Caspase-3 expression was negatively associated with the latter one (P < 0.05). Additionally, the PTEN expression was positively correlated with Caspase-3 expression in the primary gastric malignant lymphoma (P < 0.05).

CONCLUSIONSThe down-regulated expression of PTEN and Caspase-3 played an important role in progression of primary malignant gastric lymphoma. PTEN, as a molecular marker of pathobiological behaviors of tumor, contributes to tumor progression by increasing cell mobility and angiogenesis, as well as decreasing cell adhesion and apoptosis.
