ABSTRACT
Objective:To investigate the status of professional self-efficacy and its influencing factors among postgraduates in Master of Nursing Specialist(MNS).Methods:Totally 185 postgraduates from 33 universities were chosen by convenience sampling from December 2018 to January 2019 for a cross-sectional survey. Subjects completed a questionnaire covering demographic data, Professional Self-efficacy Questionnaire for Nursing Students, the Chinese version of Proactive Personality Scale and Career Social Support Inventory for Chinese College Students.Results:The score of professional self-efficacy was (92.78±13.22) . Multiple linear regression analysis showed that the sense of achievement in clinical work, proactive personality and career decision support were the influencing factors of postgraduates professional self-efficacy, with an interpretability of 40.2%.Conclusion:Professional self-efficacy of postgraduates is at upper middle level. Schools, hospitals and other relevant institutions should further improve the postgraduates cultivation model, establish high quality clinical practice bases, encourage postgraduates to actively explore career development pathway and provide adequate advices and supports, to improve the professional self-efficacy of postgraduates.
ABSTRACT
Objective To revised the Taiwan version successful aging inventory (SAI),and verify its reliability and validity in urban elderly in mainland China.Methods SAI was adjusted by culture and revised by pre-test to form a formal questionnaire.A sample of 600 elderly people in Guangzhou was chosen for a face-to-face questionnaire survey through convenient sampling.Half of the sample (n=300) was randomly selected for exploratory factor analysis,and the other was used to confirm the structural validity of SAI.Results Exploratory factor analysis extracted six common factors,including health autonomy,economic security,life adaptation,society and relative relationship,study and family.The cumulative contribution rate of six common factors was 65.366％.The fitting indexes of confirmatory factor analysis were x2/df=1.861,CFI =0.930,IFI =0.930,TLI =0.923,GFI =0.823,RMSEA =0.054,RMR =0.073.There were significant ceiling effects in the four dimensions of health autonomy,economic security,life adaptation,and family.The intemal consistency coefficient (Cronbach's α) of SAI was 0.930,and the test-retest reliability was 0.943.An average score of SAI ≥ 3.95 points was considered successful aging.Conclusion Reliability and validity of SAI are good,which can be used to measure the successful aging status of Chinese elders and track the effectiveness of health promotion measures.

ABSTRACT
Objective To evaluate the reliability and validity of the Chinese version of multidimen-sional existential meaning scale (MEMS-C) in college students. Methods The MEMS was translated into Chinese. A total of 453 college students was tested by convenience sampling method via online survery. Eighteen college students were surveyed by MEMS-C before and after a two-week interval in order to analyze the retest reliability of the scale. Results The fitting indexes of the confirmatory factor analysis were χ2=450. 510,df=74,P<0. 01,χ2/df=6. 088,GFI=0. 859,CFI=0. 930,RMSEA=0. 106,RMR=0. 074,SRMR=0. 0494. The correlation validity coefficient of the scale was 0. 617 (P<0. 01). Internal consistency relia-bility coefficient of the total scale,comprehension,purpose,and mattering factors were 0. 935,0. 893,0. 936, 0. 733. The retest reliability was 0. 908 (P<0. 01). Conclusion The MEMS-C has good reliability and va-lidity. It is suitable to measure the sense of life of college students.
ABSTRACT
Objective:To study the effects of obesity induced by high-fat diet on T lymphocyte subsets in the adipose tissue in mice.Methods:C57BL/6 male mice were randomly divided into 2 groups, the normal control group and high-fat diet group.After feeding 16 weeks, serum was separated and CHOL, TG, HDL, LDL and glucose levels were measured by automatic biochemical analyzer.The concentrations of TNF-αwere determined by ELISA kit.FACS was used to analyze the number of T cells and the percentage of subgroup in epididymal fat adipose tissue.Results:Compared with control group,body weight,weight gain,epididymal fat pad weight,perirenal fat weight,blood lipids,glucose and TNF-αwere significantly increased in high-fat diet group,but there were no difference in the thymus index and spleen index between the two groups.Compared with the control group,the mice fed a high-fat diet had increasing proportion of CD3+T cells,CD4+T cells and CD8+T cells in adipose tissue and there was a significant increase on the proportion of Th1 and Th17 sublineage in the HFD group.Conclusion:High-fat diet induced obesity can lead to the increasing proportion of CD3+T cells,CD4+T cells and CD8+T cells in epididymal fat pads and generate a progressive Th1 and Th17 bias.
