Objective: Relationships between hemispheric dominance cognitive styles and Big Five personality traits were investigated.Methods: 86 students participated in this study.By responses to Human Information Processing Survey,32 students were identified as the left hemispheric dominance style group,28 students the right hemispheric dominance style group,and 26 students the integrated dominance style group.All groups were administrated to responses to the NEO-PI-R scales.Results: The left hemispheric group had higher neuroticism and conscientiousness than the right hemispheric dominance group and integrated groups.The right hemispheric group showed more openness and extraversion than the left hemispheric group.The integrated hemispheric group showed more extraversion than the left hemispheric group,and more conscientiousness than the right group.Conclusion: Hemispheric dominance cognitive styles are related to neuroticism,extraversion,openness and conscientiousness.

Objective To determine the cut-off points of Psychological Distress Scale of Cancer Patients by using the ROC curve, in order to provide reference for clinical application of it. Methods A questionnaire containing both the Psychological Distress Scale of Cancer Patients and Symptom Checklist-90 (SCL-90) were filled by 364 cancer patients in Beijing Cancer Hospital. Later the cut-off points of the four latitudes of the Scale were evaluated by ROC curve through comparing the two scales. Results By using the latitudes of the SCL-90 scale as a reference, the areas of all the four latitudes of the Scale were:anxiety (0.815, P<0.01); depression (0.790, P<0.01); interpersonal disability (0.829, P<0.01);suspiciousness (0.670, P<0.01) respectively. The following cut-off points could result in the most ideal sensitivity and specificity: 11 for anxiety; 14 for depression; 7 for interpersonal disability and 4 for suspiciousness. Conclusions The Psychological Distress Scale of Cancer Patients can provide great values to the diagnosis of psychological problems related with anxiety, depression, and interpersonal disability, while low valuable reference for diagnosis of suspiciousness. It can provide good diagnosis value which contributes to evaluation of psychological problems of cancer patients.

Objective To study the olfactory function in Chinese patients with Parkinsons disease (PD) and its application in diagnosis and differential diagnosis of Parkinsonism Methods The thresholds of olfactory detection and identification were determined by using “five odors olfactory detection arrays” provided by Chinese Academy of Sciences for the 50 PD patients, 30 healthy controls, 30 persons with other neurological diseases, and 7 atypical Parkinsons disease patients Results The olfactory detection and identification thresholds of PD patients were significantly higher than those of the normal controls and than those with other neurological diseases But the olfactory identification threshold of PD patients was significantly higher than those with atypical Parkinsons disease The sensitivity and specificity in the olfactory test were 74 0% and 91 7%, respectively by combining the olfactory detection and identification thresholds together Conclusions The olfactory function was found significantly decreased in PD patients The olfactory test might play an important role in the diagnosis and differentiated diagnosis of PD

AIM: To investigate the extraction of anti-thrombotic contituent from Earthworm ( Pheretima). METHODS: The prothrombin time (PT)of rabbit blood and antithrombin of 14 samples that were extracted by different methods were determined in vitro. RESULTS: The sample that was percolated with 70% alcohol and the sample that was extracted by semi-bionic method were better than ones that were extracted by other methods. CONCLUSION: It is a simple and practicable method to percolate Earthworm with 70% alcohol.

Objective: To investigate relationships among Cognitive performance,cognitive styles and Neuroticism.Methods: Experimental cognitive tests were administered to 30 Highly and 30 Lowly neurotic individuals under tightened and relaxed cognitive conditions.Results: Highly and Lowly neurotic individuals did not appear any differences in total scores,but significant differences in scores of tightened-relaxed cognitive styles.Highly Neurotic individuals mostly tend to be relaxed cognitive style,and Lowly Neurotic individuals to be tightened cognitive style.Conclusion: Neuroticism does not relate with total scores of cognitive performance under tightened and relaxed cognitive condition,but with tightened-relaxed cognitive styles.

Objective: To explore the relationships between Reinforcement sensitivity, Internet service hobby and Pathological internet use. Methods: 197 junior middle school students were administrated to complete Behavioral Inhibition System and Behavioral Activation Scale(Chinese edition), Adolescents Internet Service Hobby Questionnaire, and Adolescents Pathological Internet Use Scale. Results: ①For Internet service hobby and PIUs, the Social hobby and the Entertainment hobby wre somewhat correlated to PIUs positively; however, the Information hobby and the Bargains hobby were somewhat correlated to PIUs negatively, but not significantly; ②For Reinforcement sensitivity and PIUs, Path analysis suggests, high BAS individuals were easily involved in the PIU, but high BIS individuals were not. Conclusion: Reinforcement sensitivity is a significantly predictor of PIUs, but the Internet service hobby is not.

Key words are important parts of scientific and technical articles, correctly indexing can fully reveal the core content and improve the effective communication as well as application of academic articles. Furthermore, key words are the chief indexes for measuring journal quality. In this article, we took Chinese Journal of Medical Imaging as example, deeply explored the characteristics, indexing principles and methods of journal articles in radiological imaging.

Objective　To observe rat plasma angiotensin Ⅱ (AⅡ) content change after exposed to infrasound. Methods　Infrasound was exposed to rats for 1,7,14,21 d and two hours every time in a day. After half, six, twelve, eighteen and twenty-four hours, AⅡcontent change was observed. Results　After exposed to infrasound for 1 d,AⅡcontent continued to increase in the next twenty-four hours compared to control group (P<0.01).After infrasound exposure for 7 d,AⅡ began to increase after half hour compared to control group(P<0.01), reached maximum at twelve hours, then began to decrease and turned less than that in the control group at twenty-four hours(P<0.05).After infrasound exposure for 14 d, AⅡ increased significantly compared to the control group(P<0.01).At six hours and twelve hours,there was no significant difference(P>0.05),it increased notably at eighteen hours and twenty-four hours(P<0.01).After infrasound exposure for 21 d, AⅡ began to increase at half hour compared to the contol group(P<0.05),reached maximum at twelve hours,then began to decrease and showed no significant difference at twenty-four hours(P>0.05).Conclusion　After infrasound exposure, there was irregular change of rat plasma AⅡ content at different times.

OBJECTIVE To discuss the nosocomial infection risk factors and preventive strategies in human assisted reproductive technology(ART)laboratory.METHODS The nosocomial infection risk factors in ART laboratory were analyzed,and the corresponding measures were set up.RESULTS In ART laboratory,there were nosocomial infection risk factors existing in management system,preventive process,condition of laboratory,technical program and garbage management.Corresponding measures were established to control the risk of nosocomial infection.CONCLUSIONS The nosocomial infection in ART laboratory can effectively be prevented through establishment of perfect control system,strict operation of the rules and improving technical programs.
