Objective To investigate the status of undergraduates′ sub-health and explore the relationship between personality traits and sub-health and the mediating role of self-harmony. Methods A total of 196 undergraduate nursing students in Tianjin University of Traditional Chinese Medicine were investigated by Sub-health Self-rating Scale (SSS), Self Consistency and Congruence Scale (SCCS) and Eysenck Personality Questionnaire Short Scale. Results The the total scores of the undergraduate nursing students′personality traits, self-harmony and sub-health were 22.71±4.90, 102.74±14.41, 182.54± 31.76. The neuroticism and extroversion of personality traits were significantly correlated with self-harmony and sub-health (P<0.01). Neuroticism had a significant prediction on self-harmony (β=0.37, P<0.01) and sub-health (β=-0.64, P<0.01), after controlling self-harmony, the prediction on sub-health was reduced, but still significant (β=-0.56, P<0.01);extroversion had a significant prediction on self-harmony (β=-0.27, P<0.01) and sub-health (β=0.54, P<0.01), after controlling self-harmony, the prediction on sub-health was reduced, but still significant (β=0.46, P < 0.01). Conclusions The sub-health status of undergraduate nursing students was not optimistic. Nursing students′ personality traits of psychoticism, extroversion, which directly impact on the health status, and through self-harmony indirectly affect their health level, self-harmony played a intermediary role between personality traits and sub-health.

Objective:To investigate the current status of discharged patients at risk of pressure injury and analyze risk factors of pressure injury.Methods:Using the convenient sampling method, 54 medical alliance units of Chongqing Fuling Central Hospital were selected for a cross-sectional survey. Patients at risk of pressure injury when discharged from the hospital and their caregivers were selected as the research objects from August 2019 to June 2020. The general demographic data sheet, clinical test data sheet, Braden Pressure Ulcer Risk Assessment Scale, Barthel index, and Family Caregiver Task Inventory (FCTI) were used for investigation. In this study, a total of 409 questionnaires were issued and 409 were effectively received, with an effective recovery of 100%.Results:There were 224 patients (54.8%) at light risk of pressure injury, 74 patients (18.1%) at moderate risk, 89 patients (21.8%) at high risk and 22 (5.4%) patients at extreme risk. The differences in general demographic data, clinical test data and self-care ability grade of 409 patients were statistically significant ( P<0.05) . The FCTI scores of caregivers for patients with different risk levels were compared, and the difference was statistically significant ( P<0.05) . The results of ordered logistic regression analysis showed that white blood cell count ( OR=1.103, 95% CI: 1.006-1.209, P=0.035) , care ability of caregivers ( OR=1.060, 95% CI: 1.017-1.104, P=0.005) , fecal incontinence ( OR=14.112, 95% CI: 2.505-79.497, P=0.003) , indwelling catheter ( OR=3.111, 95% CI: 1.332-7.269, P=0.009) , severe dependence ( OR=15.705, 95% CI: 2.655-92.918, P=0.002) were risk factors for the risk of pressure injury in discharged patients. Conclusions:Among discharged patients with Braden score less than or equal to 18 points, there are 45.2% (185/409) patients with moderate risk of pressure injury and above. It is necessary to focus on discharged patients with high levels of white blood cells, weak care ability of caregivers, indwelling catheters and self-care ability of heavy dependence grade to prevent pressure injuries.

Objective: To investigate the status of fatigue in maintenance hemodialysis (MHD) patients, analyze the correlation between fatigue and uncertainty and hope, and establish a multiple regression model to discuss the dependence between fatigue and uncertainty and hope situation in MHD Patients. Methods: A convenient sampling method was used to select 150 patients with renal failure who were treated with MHD in the hemodialysis center of a third-class general hospital in Tianjin from June to September, 2018. The demographic data and disease data of the patients were collected with self-designed general data questionnaire. The patients were assessed with Piper Fatigue Revision Scale, Disease Uncertainty Scale and Herth Hope Scale. Results: The results showed that the total fatigue score of MHD patients was 4.37 ± 1.17, belonging to the moderate level, with the highest score (4.95±1.35) in behavioral dimension, and the lowest score (3.48 ± 1.37) in cognitive dimension. The results showed that the score of fatigue were different in MHD patients of different ages, marital status, educational level, work status, primary disease, and the number of complications (P<0.05). The results of correlation analysis showed that the score of fatigue in MHD patients was positively correlated with the total score of uncertainty and its dimensions (r = 0.231-0.634, P<0.05). The fatigue level of MHD patients was negatively correlated with the total score of hope and its dimensions (r=-0.608- -0.323, P<0.05). Multiple linear regression showed that the independent variables entering the regression equation included marital status, number of complications, disease uncertainty and hope level score. And the determination coefficient R² was 0.530,the adjusted determination coefficient was 0.501, F=18.454, P=0.000, which had statistical significance. Conclusions The fatigue level of MHD patients is moderate, and the score of fatigue in behavioral dimension is the highest, which is influenced by age, marital status, education, work condition, primary disease and the number of complications. The level of fatigue in MHD patients was positively correlated with disease uncertainty and its dimensions, and negatively correlated with the level of hope and its dimensions.
