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 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

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.

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 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 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 discuss the influence of respiratory training and prompting effective discharging of sputum for chronic obstructive pulmonary disease (COPD) patients in acute aggravation period. Methods 50 patients were randomized into the intervention group and the control group with 25 cases in each group.The intervention group received respiratory training and prompting effective discharging of sputum while the control was only given routine treatment and nursing.The ratio of first second expiration volume to forced vital capacity, oxygen partial pressure (PaO2),carben dioxide partial pressure (PaCO2) ,blood oxygen saturation (SpO2)and the in-hospital days were compared between the two groups. Results The clinical effect in the intervention group was superior to that of the control group with shorter in-hospital days (P<0.01).Conclusion Better results could be obtained by application of respiratory training and prompting effective discharging of sputum for COPD patients in acute aggravation period.

Objective To evaluate the susceptibilities of different testing methods of tigecycline against IRAB. Methods MIC and inhibitory zone diameters of 32 strains of IRAB for tigecyclinc were determined by different testing methods.Data were analyzed by comparing the results from each method to those produced by the reference macro broth dilution method. Results The rates of sensitivity intermediate resistance detected by macro broth dilution method , agardilution , MTS and Vitek-2 instrument , disk diffusion method were as follows , 34.375%, 65.625%, 0%, 3.125%, 81.25%, 15.625%, 75%, 25%, 0%, 78.125%, 21.875%, 0%, 3.125%, 81.25%, 15.625%. Compared with macro broth dilution method ,the key major error rate of other methods was 0% by FDA breakpoints , but the CA and EA rates were less than 90%. Conclusions Tigecycline has good activity against the IRAB, with significant difference in susceptible rate among the different methods.
