Objective:To explore the mediating effect of perceived organizational support on the relationship between personality traits and perceived self-efficacy of male nurses.Methods:A total of 766 male nurses from 20 level-A general hospitals in Shandong province were selected by convenience sampling method in December 2020. The general status questionnaire, the simplified version of Big Five Personality Inventory, the Perceived Organizational Support Scale and the General Self-efficacy Scale were used to investigate them.Results:The total score and average item score of 766 male nurses' sense of organizational support was 44.05±9.31, 3.38±0.72, and the total score and average item score of general self-efficacy was 26.19±5.65, 2.62±0.57. In 766 male nurses, perceived organizational support had a partial mediating effect on neuroticism and openness, with effect values of 21.71% and 10.19%, respectively. In addition, perceived organizational support had a complete mediating effect on conscientiousness and self-efficacy.Conclusions:The organizational support and self-efficacy of 766 male nurses were above average, and organizational support played a mediating role in the relationship between neuroticism, openness, conscientiousness and general self-efficacy.Nursing managers should give more organizational support to male nurses to change the influence of neuroticism, responsibility, agreeableness and open personality traits on self-efficacy, so as to improve the level of self-efficacy of male nurses.

To investigate the effects of miRNA-10b(miR-10b)on breast cancer proliferation and apoptosis in MCF-7 and MDA-MB-231, the miR-10b mimics used to increase the endogenous expression of miR-10b, and miR-10b inhibitor used to decrease the endogenous expression of miR-10b, were stably transfected into MCF-7 and MDA-MB-231 breast cancer cells. The expression level of miR-10b was determined by real-time PCR. The effects of miR-10b on proliferation were evaluated by MTT assay, while cell cycle assay and the apoptosis rate were measured by flow cytometry. Bioinformatic software was used to predict the potential targets of miR-10b, and 3′UTR luciferase reporter and qRT-PCR assay were used to verify a direct target of miR-10b. The expression levels of caspase-3 and p21 protein were measured by Western blot. Results confirmed that over-expression of miR-10b could promote the proliferation of breast cancer cells and inhibit the apoptosis by up-regulating the endogenous miR-10b, while the miR-10b inhibitor could restrain the proliferation of breast cancer cells and increase the apoptosis by reducing the endogenous miR-10b. In conclusion, miR-10b could negatively regulate the expression of caspase-3 and p21 by targeting TP53INP1, hence highlighting its potential as an oncogene in breast cancer cells.

A face-to-face survey was conducted with the self-designed general information questionnaire for the elderly and their main caregivers, QOL-Alzheimer's Disease Scale (QOL-AD) , Chinese version of the Disability Assessment for Dementia (CDAD) , Montreal Cognitive Assessment (MoCA) , Short version of Geriatric Depression Scale, Geriatric Depression Scale-15 (GDS-15) , Neuropsychiatric Inventory Questionnaire (NPI-Q) , Zarit Burden Interview (ZBI) .Results:150 valid questionnaires were collected.The total score of QOL-AD was (33.40±2.84) , and the total score of caregiver-rated QOL-AD was (31.45±3.44) , the difference was statistically significant ( P< 0.01) ; Age, education level, types of comorbid diseases, cognitive function, depression and burden of care were the main influencing factors of self-rated quality of life ( P< 0.05) ; the relationship between caregivers and the elderly, education level, self-rated health status, daily living ability, neuropsychiatric symptoms and burden of care were the main influencing factors of self-rated quality of life ( P< 0.05) . Conclusions:There are differences between self-rated QOL and caregiver-rated QOL in the elderly patients with Alzheimer's disease. It is suggested to reduce the differences through improving the accuracy of self-assessment and caregiver assessment, so as to improve QOL of the elderly patients with Alzheimer's disease.

Objective:To explore the mediating effect of self-efficacy between personality traits and learning engagement in nursing undergraduates.Methods:In December 2020, 2 170 4-year nursing undergraduates from 6 full-time universities in Shandong Province were selected as the research subject by convenience sampling. The Chinese Big Five Personality Inventory-15 (CBF-PI-15) , the Work Engagement Scale, and the General Self-Efficacy Scale (GSES) were used to conduct a cross-sectional survey. AMOS 17.0 was used to establish the structural equation model.Results:Among 2 170 undergraduate nursing students, the average scores of 5 dimension items of CBF-PI-15 in descending order were agreeableness (3.63±0.87) , sense of responsibility (3.24±0.84) , extroversion (2.58±0.68) , openness (2.56±1.00) , and neuroticism (1.76±1.19) . The total scores of 2 170 nursing undergraduates on the Work Engagement Scale and the GSES were (67.24±11.34) and (29.64±5.47) respectively. The self-efficacy of nursing undergraduates had a partial mediating effect between neuroticism, sense of responsibility, openness personality traits and learning engagement, and the effect values were 42.64%, 30.21%, and 48.67%, respectively.Conclusions:The learning engagement of nursing undergraduates is at the upper middle level. Nursing educators can change the influence of neuroticism, sense of responsibility, and openness personality traits on learning engagement by improving the self-efficacy of nursing students, thereby increasing the level of learning engagement of nursing undergraduates.

Objective:To observe the effect of early mechanical ventilation on the expression of inflammatory factors and prognosis of patients with severe traumatic brain injury (sTBI).Methods:From January 2017 to December 2020, 138 patients with sTBI admitted to the department of the emergency of Xinhua Hospital Chongming Branch were enrolled. Although some patients were admitted to hospital without acute respiratory failure, their Glasgow coma score (GCS) were less than 8, they bad risk of hypoxia, so early mechanical ventilation was required. According to the patient's condition and the willingness of family members, patients were divided into mechanical ventilation group (tracheal intubation mechanical ventilation) and conventional oxygen inhalation group (nasal catheter or mask oxygen inhalation) in the end. The arterial partial pressure of oxygen (PaO 2), arterial partial pressure of carbon dioxide (PaCO 2), oxygenation index (PaO 2/FiO 2), tumor necrosis factor-α (TNF-α), and interleukin (IL-6, IL-10) levels at admission, preoperation and 72 hours postoperation, as well as GCS before operation and 1 week after operation, the duration and number of patients successfully evacuated from the ventilator within 1 week after surgery were observed and analyzed. Results:A total of 138 sTBI patients were enrolled in the study, including 72 cases in the mechanical ventilation group and 66 cases in the routine oxygen inhalation group. In the two groups, PaO 2, PaO 2/FiO 2 and IL-10 were higher, and PaCO 2, TNF-αand IL-6 were lower at 72 hours post operation than that before operation. Moreover, the changes in the mechanical ventilation group were more significant than those in the conventional oxygen inhalation group [PaO 2 (1 mmHg = 0.133 kPa): 94.6±7.7 vs. 92.5±6.8, PaO 2/FiO 2 (mmHg): 351±94 vs. 319±89, IL-10 (ng/L): 8.2±2.7 vs. 7.4±1.8, PaCO 2 (mmHg): 35.6±1.8 vs. 37.5±2.7, TNF-α(ng/L): 71.5±6.3 vs. 96.8±15.5, IL-6 (ng/L): 10.8±3.9 vs. 14.4±6.5, all P < 0.05]. There were 17 patients with severe respiratory insufficiency or failure in the conventional oxygen inhalation group before operation. Compared with the conventional oxygen inhalation group, the GCS score (11.7±3.1 vs. 9.1±4.6) and the proportion of successful weaning [62.5% (45/72) vs. 44.0% (29/66)] were significantly higher, and the duration of successful weaning (hours: 63.5±28.6 vs. 88.1±33.9) was significantly shorter in the mechanical ventilation group 1 week after operation. Conclusion:Early mechanical ventilation in sTBI patients can significantly improve oxygen supply, inhibit the release of pro-inflammatory factors, reduce secondary brain damage, and effectively improve the prognosis.
