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 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.

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 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 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.

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 investigate the urinary iodine level and the thyroid function of early pregnant women in Qingdao,to explore the relationship between the iodine nutritional status and hypothyroidism.Methods 326 early pregnant women (<12 gestational weeks)were collected.The urinary iodine concentration and serum thyroid stimulating hormone (TSH),free thyroxine (FT4 ),thyroid peroxidase antibody (TPOAb)were detected. Results The median of urine iodine of pregnant women was 176.57μg/L,and the ratios of iodine deficient,iodine adequate,iodine more than adequate and iodine excessive groups were 3 8.65%,41.10%,15.95% and 4.30%.The total ratio of innormal urine iodine was 58.9%(192 /326).The differences between the ratios of the iodine deficient group,iodine excessive group and iodine adequate group both had statistically significant(χ2 =4.308,P <0.05;χ2 =4.826,P <0.05 ).There was no effect of iodine intake levels on serum thyroid peroxidase antibody.Conclusion There is no iodine deficiency among early pregnant women in Qingdao,but still individuals expose iodine deficiency.Iodine deficiency and iodine excessive are the risk factors of hypothyroidism during early pregnancy women,so we commend to detect the urinary iodine level.

Background and purpose:Paclitaxel and cisplatin were demonstrated to be effective and well-tolerated for advanced gastric cancer.The clinical efficacy of hyperthermic intraperitoneal perfusion(CHPP) has been established in numerous studies in recent years.The purpose of the study was to evaluate the efficacy and toxicities of paclitaxel combined with CHPP with cisplatin in the treatment of patients with advanced gastric cancer.Methods:51 patients with advanced gastric cancer were randomized into systemic chemotherapy group(25 patients) who received paclitaxel 70 mg/m2,iv,1/wk?8wk,DDP 25 mg/m2,iv,d1-3,reapeated every 3 weeks for 4 cycles and systematic plus CHPP group(26 patients)who received paclitaxel 70 mg/m2,iv,1/wk?8wk,DDP 60 mg/m2,CHPP,d1,8,22,29,and abdomen hyperthermia treatment twice a week in the whole chemotherapy period.Results:The response rate(CR+PR),the clinical benefitial response(CBR) in systematic plus CHPP group were 65.4% and 92.3%,and those in systemic chemotherapy group were 36.0% and 68.0%.There was obviously a statistical difference between two groups(P0.05).The major toxicities were myelo-suppression and nausea/vomiting.There was no significant difference in side-effect between the two groups.Conclusions:Paclitaxel administered by weekly infusion combined with hyperthermic intraperitoneal perfusion chemotheraphy with cisplatin in the treatment of advanced gastric cancer is effective and tolerable.It is worth studying in the future.
