ABSTRACT
Objective To investigate the radioactivity level of natural rocks in Lhasa in order to obtain the radionuclide contents and availiability of the rock.Methods Radiation monitoring and sampling were carried out in the natural rock mining area in Lhasa,and the contents of radionuclides in the samples were analyzed.Both internal and external exposure indexes were calculated,and the rocks were classified according to the relevant national standards on building materials.Results The average specific activity of 40K,226Ra,232Th and 238U in the rock samples were 912,59.0,77.1,and 64.4 Bq/kg,respectively.Internal and external exposure indexes were both less than 1.Conclusions The radioactivity level in natural rocks in Lhasa were lower than the national levels.The natural rocks could be used as main building materials and Class A decoration materials.
ABSTRACT
Objective To investigate the relationship between Post stroke depression (PSD) and Post stroke cognitive impairment (PSCI) using proton magnetic resonance spectroscopy.Methods 82 patients of acute stroke,which were met with the third edition of the Chinese Classification of Mental Disorders (CCMD-Ⅲ) and expert consensus of cognitive impairment since January 2012 to December 2012,Select continuously 82 patients who are hospitalized in our hospital due to acute stroke from January 2012 to December 2012 from Zhongnan Hospital of Wuhan University,were examined by 1H-MRS in one month.They were divided into PSD and PSCI simultaneously (n =19),PSD (n =21),PSCI (n =22) and control group (n =20).Results The differences between PSD and PSCI was not significant.On hippocampus japonicas,the Cho/Cr ratio in patients of A group (left (1.05 ± 0.10),right(1.18 ± 0.15)),showed higher than those in B group (left (0.84 ± 0.10),right (0.88 ± 0.08)),C group (left(0.88 ±0.08),right (0.87 ±0.07)),D group(left(0.87 ±0.06),right(0.89 ±0.06)).The difference was statistically significant.PSD and PSCI promoted each other in influencing Cho/Cr ratio.Conclusion There is no significant relationship between PSD and PSCI in the produce of disease,and they can promote each other in hippocampus japonicas Cho/Cr ratio.
ABSTRACT
Studies have shown that the compliance of secondary prevention of ischemic stroke is not ideal. Among the factors that impact the compliance of secondary prevention, the correlation of the gender, age or disease severity has no clear conclusion. However, the married, the higher proportion of medical reimbursement, a better understanding of the disease, early intervention, the doctor's degree of attention, and a good doctor-patient relationship may improve the compliance of secondary prevention of ischemic stroke.
ABSTRACT
Objective To revise the manipulation tactics scale (MTS) and examine its reliability and validity. Methods 583 college students were assessed with MTS. Results ①Through item analysis and explore factor analysis, the revised MTS contained 24 items and 6 subscales which could explain 64.559% of the total variances. ②The results of confirmatory factor analysis showed that the revised MTS had good construct validities. By means of personality traits and social relationship as criteria, the results suggested the criteria incidental validity were sound. ③The Cronbach' s coefficients of the scales were 0.714,0.866, and test-retest reliabilities were 0.701,0.837. Conclusion The revised MTS has good reliability and validity.
ABSTRACT
Objective To explore the mechanism of personality between attachment and defense style in college students. Methods 291 students were surveyed with Eysenck Personality Questionnaire-R Short Scale (EPQ-RSC, Chinese Adaptation), Experience of Close Relationship Inventory(ECR, Chinese Adaptation) and Defense Style Questionnaire ( DSQ). Results ①Unmature defense style had significant positive correlations with anxiety, avoidance, neurotism and psychoticism(r = 0. 19,0.45,0.51,0. 19, P<0.01) ,and had significant negative correlation with extroversion(r= -0. 25, P<0. 01 ) . ②Extroversion acled as part meditator between attachment and unmature defense style. ③Neurotism served as part meditator between anxiety and unmature defense style. Conclusion Attachment is a remarkable predictor of unmature defense style and has indirect influence on it through neurotism and psychoticism.
ABSTRACT
Objective To study the ego identity,mental health and their relationship among students in athletes.Methods 110 students in athletes and 122 athletes in students were measured with identity status scale and athletes' symptom checklist.Results ①Students in athletes have higher "present serf-commitment" (5.09±1.07)and lower "crisis in the past"(2.19±1.12)than athletes in students.The two demonstrate the obvious difference on the distribution of identity status.The percentage of students in athletes obtaining A is lower than that of athletes in students ,while the percentage of students in athletes obtaining D and MD is higher. ②Comparing with the norm,students in athletes have higher level on the factors of sematizafion (1.98±0.42),compulsion (2.21±0.51),interpersonal sensitivity(2.09±0.53),depression (1.85±0.53),anxiety ( 2.47 ～0.58 ),paranoid (1.98±0.21),psychoticism (1.79±0.22) and total average marks (2.00±0.34),lower level on the factors of hostility (1.43±0.48)and cognitive(1.64±0.31). ③Three domains of ego identity exit obvious negative correlation with the sores of psychological symptoms.ANOVA confined that the more advanced ego identity is,the better mental health is.Conclusion Ego identity and mental health of students in athletes have their own features,and ego i-dentity will influence mental health.
