Celastrol cell line Methods From 1st december 2018 to 31th March 2019, 658 nurses were selected from a class Ⅲ hospital in Jinan of Shandong province by convenience sampling method. link2 700 questionnaires were gived out and recoveried, with 658 effective questionaires and the effective recovery rate was 94.0%. The data of nursing work life quality, type of workplace violence, frequency of workplace violence and general social demographic were collected. Results The mean total score of the quality of nursing work life was (174.61±27.61) . The lowest subscale is work life-home life (61.9%) . There were no statistical difference in the total scores of nurses with different ages and working years (P> 0.05) , while the frequency of night shift, and working hours per day had significant impact on the quality of nursing work life (P less then 0.05) . The total score of nurses who were not suffered from workplace violence was much higher than the nurses who were suffered from language violence or physical assault (P less then 0.05) , the higher the frequency of the violence, the score of the quality of nursing work life was lower (P less then 0.05) . Conclusion The quality of nursing work life of nureses who suffer from workplace violence is in a bad situation, nursing managers should give different intervention measures according to the personal characteristics of nurses to improve the quality of nursing work life.Objective To explore the establishment of disease assessment index model in silicosis patients. Methods In October 2018, 171 silicosis patients who were hospitalized from November 2014 to November 2015 were selected as the study subjects. According to the standard of death risk, the subjects were divided into two groups, including the group without death risk (153 cases) and the group with death risk (18 cases) . Through literature analysis and clinical experience, the variables related to silicosis were preliminarily screened. Multifactorial logistic regression analysis variables were used to analyze the relationship between the variables and the risk of death. The variables associated with the risk of death were selected as the final variables to establish the disease assessment index model. And the receiver operating characteristic (ROC) curve was used to evaluate the clinical application of the disease assessment index. Results Five variables of Modified British Medical Research Council Respiratory Questionnaire (mMRC) , pulmonary function injury, pneumoconiosis stage, aggravation of the disease and complications were selected as the variables of the disease assessment index, and the assessment index score ranged from 1 to 11 points. The area under the ROC curve of disease assessment index was 0.747 (95%CI 0.590-0.904) , which could better identify the death risk of silicosis patients. With the increase of disease assessment index score, the death risk of silicosis patients increased. When the cutoff value was 7, the sensitivity and specificity were 0.667 and 0.876, respectively, for the risk of death of silicosis patients. The results of cross-validation showed that the correct discrimination rate of the disease assessment index to the risk of death was 66.7%. Conclusion The disease assessment index can predict the death risk of patients with silicosis, and can evaluate the disease comprehensively.Objective To understand and predict the situation of occupational diseases in Changsha, and to provide theoretical basis for the scientific formulation of occupational diseases prevention, control strategies and measures. Methods In April 2019, the data of occupational diseases incidences from 2010 to 2018 were collected. The original GM (1, 1) grey model and buffer operator improved model were established, and compared their prediction effect. The model with the smallest average relative error was selected to predict the incidence of occupational diseases during 2019-2023. Results The relative accuracy of the original GM (1, 1) grey model and the first-order and second-order buffer operator improved model were 80.92%, 97.71%, 99.64%, respectively. And the c values were 0.74, 0.28, 0.09, and the P values were 0.67, 1.00, 1.00, respectively. It was predicted that the incidence number of occupational diseases in Changsha during 2019-2023 would be 40, 39, 39, 38, 37, respectively. Conclusion The buffer operator improved model is suitable for the prediction of the original data series with high volatility, and it can fit the incidence of occupational diseases in Changsha.Objective To study the characteristics of the lens turbidity after long-term exposure to low intensity 635nm laser. Methods Cluster sampling method was adopted to select 812 employees in a laser leveler workshop in a city of Guangdong Province from January 2014 to December 2018. They were divided into the control group, diffuse reflection (DR) group and direct vision (DV) group for retrospective observation and analysis of lens turbidity. The laser irradiation intensity of each group was investigated, the position and shape of lens opacity were analyzed, and the influencing factors were statistically analyzed with the repeated measurement data of dichotomy. Results The laser irradiance and radiant exposure of DV group were between 0.72×10(-4) and 9.92×10(-4) mW/cm(2) and between 2.61×10(-2) and 1.53 J/cm(2), respectively. link3 The subjects were mainly diagnosed with lens turbidity lesion, especially for the DV group. Most of lesions occurred in the pole and periphery of the anterior cortex. The lesions exhibited multipoint patterns with greyish white color. The turbidity rates in DV group (before work and work for 1, 2, 3 years) were 0%, 1.99% (8/402) , 4.98% (20/402) and 6.72% (27/402) , respectively, in the order of observation points. The statistical analysis of single factor effect showed that the turbidity rate was higher in DV group and higher in the second year in the DV group (P0.05) . Conclusion Lens turbidity lesion can be caused by long-term exposure to low intensity 635 nm laser, so the product safety classification should be strictly strengthened. It is necessary to strengthen the protection of laser photochemical damage in the production process.Objective To evaluate the infection rate and influencing factors of hepatitis E virus (HEV) among key occupational population in Tianjin, so as to help occupational population to carry out HEV prevention and control.
