RESUMO
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.
RESUMO
OBJECTIVE：To investi gate the potential mechanism of couplet medicine of Cuscutae Semen-Lycii Fructus in the treatment of premature ovarian failure. METHODS ：Main active components and related targets of couplet medicine of Cuscutae Semen-Lycii Fructus in the treatment of premature ovarian failure were obtained from TCMSP ，GeneCards and OMIM database. The intersection genes between them were screened using Venn online tool. Cytoscape 3.7.0 software was adopted to establish the active ingredients-target network and the PPI network. GO and KEGG pathway enrichment analysis on intersection genes were carried out by DAVID database. Finally ，an active component-target-key pathway network was constructed. RESULTS ：Totally 42 active components ，231 and 1 913 targets for active components and disease were obtained from couplet medicine of Cuscutae Semen-Lycii Fructus. The components with high node degree included quercetin ，kaempferol，β-sitosterol，isorhamnetin，glycitein， stigmasterol and sesamin ，etc. There were 149 intersection genes between the active component targets and premature ovarian failure targets. PPI network contained 149 nodes and 2 970 edges，with an average node degree of 39.9 and an average medium of 0.005 4. The results of GO analysis showed that molecule function of the above-mentioned genes mainly involved protein binding ， enzyme binding ，etc. Biological process mainly included that positive regulatio n of transcription from RNA polymerase Ⅱ promoter，positive regulation of transcription DNA-templated ， Cell components mainly included nucleus ，cytoplasm，etc. Signaling pathway mainly involved cancer signaling pathway ， hepatitis B signling pathway ，PI3K/AKT signaling pathway ， MAPK signaling pathway ， etc. The results of active 617693370@qq.com component-target-key pathway network showed that active components of Cuscutae Semen and Lycii Fructus were flavonoids and alcohols ；key target included AKT 1，TP53， VEGFA，IL6，TNF，etc. Signaling pathway mainly involved cancer signaling pathway ，hepatitis B signaling pathway ，PI3K/AKT signaling pathway ，MAPK signaling pathway ，etc. CONCLUSIONS ：Through PI 3K/AKT signaling pathway and MAPK signaling pathway，the active components of couplet medicine of Cuscutae Semen-Lycii Fructus may act on AKT 1，TP53 and other targets ， and then play a therapeutic role on premature ovarian failure. The Potential active components stigmasterol ，sesamin and potential targets IL 6，TNF were found.
RESUMO
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 χ2/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 internal 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.
