Objective: To study the relationship between personality type and risky decision-making.Methods: By means of cluster sampling, 210 undergraduate students from military school were investigated with MBTI-G personality type scale and self-made decision-making scale. We randomly divided 210 undergraduate participants into two groups. The first group (N=109) received a positive format, the second (N=101) a negative format.Results:First, in positive framing, the results of analysis in dimensions of Sensing-Intuition and Thinking-Feeling revealed a significant relationship between option and personality types. In negative faming, the results of analysis in dimensions of personality types indicated that options appeared to be independent of the personality types. Second, the preferences for the risky option of the subjects scoring highly on Introversion, Sensing, Feeling and Perceiving were almost the same as that for the safe option in the positive framing, their preferences for the risky option were significantly more obvious than that for the safe option in the negative framing. Subjects scoring highly on Thinking and Judging were likely to prefer the risky option in both positive and negative framing, their preferences for the risky option were more distinct in the negative frame(?2=4.39,P=0.036;?2=10.47,P=0.001). The analyses in Extraversion and Intuition indicated that options appeared to be independent of the personality type. Conclusion: Personality type is related to decision-making behavior and is predictor of risk-taking.

Objective:To investigate job burnout status of doctor and nurse in China. Methods: 218 doctors and nurses were assessed by MBI-HSS. Results: 42.1% subjects got high or moderated scores on Emotional Exhaustion, 22.7% subjects got high or moderate scores on Depersonalization and 48.6% subjects got low or moderate scores on personal accomplishment. Female subjects got higher scores on Emotional Exhaustion than male subjects Compared with.subjects with higher level education, subjects with lower level education got higher scores on Emotional Exhaustion, however, lower scores on Personal Accomplishment.Conclusion:Some subjects are found to experiences job burnout. To prevent or cure job burnout, more attention should be paid to female and persons with lower level education.

Objective: To find out some clues in the personality types of Chinese dental school applicants and provide useful information in the cross-culture research between western and eastern countries, and supply guidance for Chinese educators.Methods:The Chinese version of MBTI (Form G) was used to test the personality styles of 332 dental school applicants from the mainland of China, and the personality styles of dental school applicants between Chinese and English were compared. Results:In mental aptitude, the percentage of introversion (I) type in Chinese samples (56.8)was higher than Extroversion (E) type(43.2), while it was contrary in English samples (15.7 vs. 84.3)and the difference was significant (?~2=111.49, P

Objective To explore the feasibility of team-based learning (TBL) for practice teaching of the aerospace nutrition and food hygiene.Methods A total of 90 students were investigated,and were divided into the TBL group (n=46) and the TL group (n=44) by simple random sampling.After the experiment teaching,a test and questionnaire were used to compare the teaching effect of TBL group and TL group.SPSS 18.0 was used for date and the data was analyzed by Independent-Samples t test and Chi-square test.Results Students in TBL group achieved higher mean test scores (85.70 ± 3.47) compared with students (74.10±2.41) in TL group and the difference was statistically significant (t=8.703,P=0.000).The results of the questionnaire showed that,compared with the TL group,TBL group students more agreed with the positive impact of the teaching methods on their team work ability,interpersonal skills,communication ability,problem-solving and self-learning and other aspects,and the differences between two groups were statistically significant (P＜0.05).In addition,the majority of the respondents in TBL group [93.5％ (43/46)] were satisfied with TBL.Conclusions TBL teaching is better than the TL teaching,and it can significantly improve students' comprehension of knowledge and enhance their learning effect.

Objective To characterize the viability and transgene expression of articular chon-drocytes cultured in 3-Dimensional scaffolds provided by four types of carriers.Methods Articular chondrocytes from rabbit knees were cultured and infected with adenovirus that could express green fluo-rescence protein (AdGFP) and GL3 luciferase (AdGL3-Luc).The viability and gene expression were determined with fluorescence microscopy and luciferase assays in four types of scaffolds;type I collagen sponge, fibrin glue, hyaluronan and open-cell polylactic acid (OPLA).Cartilage matrix production was assessed by Alcian blue staining.Results Articular chondrocytes of rabbits were effectively infected by AdGFP and exhibited sustained GFP expression.All the tested scaffolds supported the survival and gene expression of the infected chondrocytes.However, the highest transgene expression was observed in the OPLA carrier (P<0.01).Alcian blue-positive matrix materials were readily detected in OPLA cultures four weeks later.Conclusion OPLA supports the highest transgene expression and is the most conduc-tive scaffold for matrix production, suggesting that OPLA may be a suitable scaffold for cell-based gene therapy of articular cartilage repair.
