Objective To study the cautious behaviors of mice under dangerous conditions caused by height. Methods An elevated beard task was designed,in which the mice were employed to get through a horizontally elevated beard. The time of getting through and number of looking-aside behaviors were recorded under different experimental conditions with different elevated height and visual cues. Results The mean time of getting through the elevated board with a height of 60cm was significantly longer than that of 15cm [(22.55±14.64)s Vs (12.16±8.67)s, P<0.05]. The number of looking-aside behaviors decreased from (2.95±1.73) to (1.95± 1.27) , P <0.05 ,when the visual cues on potential danger were controlled. Conclusion The cautious behaviors increase with the height of elevated board and decrease when controlling for the visual cues on potential danger, which indicate a trade-off relationship between the perceived danger and cautious behaviors.

Objective To investigate the ability of theory of mind use in elders,and determine the role of inhibitory control in the use of theory of mind. Methods The participants included 30 young-old people ,30 oldold people and 30 young people. Their ability of theory of mind use and inhibitory control were examined with The Referential Communication Task and Hayling Sentence Completion Test,respectively. Results The correct rate of referential communication task was significantly lower in old-old people (0.43 ± 0.32) than those of young-old people (0.69 ±0.24, P=0. 001 ) and young people (0. 77 ±0. 25, P＜0. 001 ). Partial correlation analysis showed that the total errors in Hayling Test-B was negatively correlated with the correct rate of Referential Communication Task ( r= -0.442, P＜0.001 ). Hiberarchy regression analysis showed that the total errors in Hayling Test-B entered the equation ( β = -0.451, P＜0. 001 ) and could independently explained 16.8% of the variance (△R2 = 0. 168, △F = 19.359, P ＜ 0.001 ) after controlling for age. Conclusion Old-old people show worse performance in the use of theory of mind. The impairment of inhibitory control can partly explain the decline of theory of mind use in old-old people.

Objective: Exploring the developmental vitial moments and process of career identity.Methods: A case subject was administered structured interview and tested by Career Identity and the Related Factors Questionnaire,Chinese Self-Efficacy Scale,QZPS and MBTI-G.Results: There were several vital moments in the process of career identity,such as the first time to think about career identity,and select a major,the first time to choose career and get employed,meet the organizational changes,find a new job again and get promotion.The present crisis of career identity reflected some unresolved problems of previous developmental periods.Conclusion: The individual's objective behavior toward career choice,decision-making,continuous exploration and efforts were of great benefit to career identity.

The operation signature regulation in force in China means giving the right of signature agreeing to the operation to a third party including the patients family. This kind of practice not only goes against the principle of informed consent and relevant regulations as stipulated in the General Rules of the Civil Law of the Peoples Republic of China and the Contract Law of the Peoples Republic of China, but is also likely to cause medical disputes. For this reason, the signatory right agreeing to the operation ought to belong to the patient himself unless it is a legal matter.

Objective:To test the validity and reliability of BSRI (Bem Sex Role Inventory) in Chinese culture Method:340 undergraduates from three universities in two cities were collected as the subjects They all completed the BSRI Item analysis and factor analysis were done followed by item revision making the inventory more suitable to Chinese culture Result:The new brief scale was composed of 14 masculine items and 12 feminine items The reliability and validity were improved after the revision Conclusion:The new brief scale is more suitable to Chinese culture

Objective:To investigate an effective paradigm to test false belief understanding for the Autism. Method:By comparing the multimedia animation presentation and the traditional presentation, 20 autistic children's false belief understanding was analyzed as well as the normal children's.Results:Animation presentation was really helpful to both groups, especially for the children with autism. The performance might be underestimated due to the application of the traditional presentation in false belief tasks.Conclusion:The autistic children's theory of mind can be measured much closer to the truth if the more apt tasks are considered.

Objective: To explore the feature of theory of mind(ToM) in schizophrenic patients and the influencing factors. Methods: Subjects were 108 patients with schizophrenia, 21 with affective disorders and 21 normal subjects. Picture-story tasks, PANSS and WAIS-R were used to assess the patients' ToM, symptoms and intelligence. Results:It was found that the scores on first-order theory of mind tasks of schizophrenic patients with IQ below 70 were lower than normal subjects'(D = -56.58,P

Objective To explore the change of of plasma TSP-1 level in patients with coronary atherosclerosis and its relationship with the degree of coronary artery stenosis and related plasma cytokines.Methods A total of 79 patients with chest pain were divided into low score group (n =27),medium score group (n =26),and high score group (n =26) according to Gensini score.Another 27 normal controls were included as control group.The levels of plasma TSP-1,hs-CRP,MMP-9 and TGF-β1 were detected by enzyme-linked immunoassay,and the relationship between TSP-1 and Gensini score,hs-CRP,MMP-9 and TGF-β1was analyzed.Results There were significant differences in level of plasma TSP-1 between four groups (P ＜ 0.05).The level of TSP-1 in plasma was correlated with hs-CRP (r =0.4979,P ＜ 0.001),MMP-9 (r =0.3940,P ＜ 0.001) and TGF-β1 (r =0.4889,P ＜ 0.001).The multiple stepwise linear regression analysis showed that there was a correlation between the degree of coronary artery stenosis and the plasma TSP-1 level.Conclusion Plasma TSP-1 level can be used as a biomarker for coronary stenosis.
