ABSTRACT
Objective:To explore the influence of mindfulness on perceived stress in psychiatric nurses and the mediating effect of resilience.Methods:A total of 427 psychiatric nurses from a psychiatric hospital in Beijing were selected.Five-facet mindfulness questionnaire(FFMQ), Chinese-version perceived stress scale (CPSS) and Connor-Davidson resilience scale (CD-RISC) were used in this survey.Pearson correlation analysis and multiple stepwise regression analysis were performed using SPSS 24.0.And mediating effect was performed using AMOS 24.0.Results:The total score of psychiatric nurses' perceived stress was (37.89±7.16). Among all psychiatric nurses, 66.74% were under high pressure and 20.84% were under great pressure.The perceived stress was negatively correlated with mindfulness(123.69±10.82, r=-0.65, P<0.01) and resilience(85.40±17.87, r=-0.67, P<0.01), and mindfulness was positively correlated with resilience ( r=0.50, P<0.01). The direct effect of mindfulness on perceived stress was -0.15, the indirect effect was -0.34, and the total effect was -0.49. Conclusion:Resilience plays a partial mediating role between mindfulness and perceived stress psychiatric nurses.
ABSTRACT
Objective:To explore the relationship between early maladaptive schemas, defense styles and mental health in patients with depression, and to investigate the mediating effects of defense styles between early maladaptive schemas and mental health.Methods:A total of 87 outpatients with depression were assessed with the Young schema questionnaire-short form 2(YSQ-SF2), defense style questionnaire(DSQ), symptom checklist-90(SCL-90) and Beck depression inventory(BDI). SPSS Process program and Bootstrap method were used to explore the mediating effect of defense styles.Results:The scores of abandonment/instability were higher in females than those in males (2(0.5, 4), 0(0, 1.25), Z=-2.963, P=0.003) while the score of emotional inhibition was higher in males than in females (1(0, 3), 0(0, 2), Z=-2.318, P=0.02). The total score of SCL-90 was positively predicted by vulnerability to harm or illness and emotional deprivation, with an explanatory variation rate of 27.7%.The number of SCL-90 positive items was positively predicted by social isolation/alienation and abandonment/instability, with an explanatory variation rate of 19.3%.Immature defense styles fully mediate the relationship between social isolation/alienation and mental health, as well as between abandonment/instability and mental health. Conclusion:Social isolation/alienation and abandonment/instability affect the mental health of patients with depression by the mediating effect of immature defense styles.
ABSTRACT
[Summary] A more conservative approach for endometrial cancer ( EC ) is desirable in women who have requirement to preserve fertility, without compromising their survival .In this article, we tried to formulate clinical recommendations of preserving fertility based on suggestions of European Society of Gynaecological Oncology ( ESGO) in 2015 and relevant research progress .
ABSTRACT
In order to improve the precision and robustness in determination of soluble solids content ( SSC) of ‘Fuji ’ apple by NIR spectroscopy and eliminate the effect of origin variability on the accuracy of NIR calibration models for the SSC, sample set partitioning based on joint x-y distances ( SPXY) was used to select representative subset from the apple samples of 4 different origins. As a comparison, partial least square ( PLS) was used to establish local origin and hybrid origin models for the prediction of SSC in apple. Competitive adaptive reweighted sampling ( CARS ) and successive projections algorithm ( SPA ) were implemented to select effective variables of the NIR spectroscopy of SSC of apple. The results indicated that the PLS model established based on the 4 origin apple samples performed better than local origin and other hybrid origin models. The model could be effectively simplified using 16 characteristic variables selected by CARS-SPA method from full-spectrum which had 3112 wavelengths. The correlation coefficient (Rp) and root mean square error of prediction (RMSEP) were 0. 978 and 0. 441 oBrix, respectively for SSC. It was found that the model developed by more samples of different origins combined with effective wavelengths showed good prediction ability for apple sample of unknown origin, which indicated that it could significantly reduce the origin effect on the robustness of NIR models for SSC of apple.
ABSTRACT
<p><b>OBJECTIVE</b>To establish an HPLC method for determination of three organic acids in Schisandrae Chinensis Fructus.</p><p><b>METHOD</b>The separation was performed on a C18 column with acetonitrile-15 mmol x L(-1) KH2 PO4 (1:99) and methanol-0.5% acetic glacial as the mobile phrase to determine the content of kinic acid, citric acid, and protocatechuic acid.</p><p><b>RESULT</b>Three kinds of organic acid can be detective in different samples, and the average content of the three organic acids were about 18%, among which the citric acid was the highest (18%).</p><p><b>CONCLUSION</b>Since organic acids is an important parts of the material basis in Schisandrae Chinensis Fructus, it is necessary to carry out the pharmacological research associated with the function of Schisandrae Chinensis Fructus. Further, it will provide scientific basis for the drug relevance research between material basis and efficiency, as well as the foundation for the relevance research on the properties and Five Tastes of traditional Chinese medicine.</p>
