Objective To investigate the situation of wearing protective equipment in the process of X-ray radiation examination (including DR and CT) in a 3A general hospital, so as to provide technical basis and solutions for better reducing the radiation dose of accompanying patients. Methods From November 1, 2018 to June 30, 2019, the accompanying examinee 6 who had to stay in the examination room during the radiology examination (X-ray and CT examination) of a 3A general hospital from June 1, 2018 to June 30, 2019 was selected 535 people were divided into three groups according to whether they were reminded and instructed to wear protective equipment group A was not reminded (group A) , group B was reminded to wear protective equipment, and group C was reminded and instructed to wear protective equipment (Group C) . Results The wearing rates of protective equipment of the three groups were 35.0% (744/2126) , 85.2% (1858/2181) and 91.0% (2028/228) , and the complete wearing rates were 15.0% (319/2126) , 54.8% (1195/2181) and 88.0% (1960/228) , respectively. 4% (1450/3060) , 28.6% (876/3060) , 24.0% (734/3060) , respectively. 523 patients refused to wear protective equipment. The main reasons were emotion (33.8%, 177/523) and time (32.5%, 170/523) . Conclusion The intervention of radiation workers can effectively improve the correct wearing rate of protective equipment and reduce the radiation exposure of accompanying people.Objective To explore the relationship between job stress, job burnout and turnover intention of operating room nurses in a tertiary hospital in Shandong Province. Methods From January 2016 to January 2019, the operating room nurses with an average daily operation volume of more than 200 operating rooms in a tertiary hospital in Shandong Province were selected as the research objects. The work pressure, job burnout and turnover intention of nurses were investigated with the Chinese nurses' job stressor scale, job burnout table and turnover intention table. Pearson related factors were used to analyze job stress, job burnout and turnover intention Multivariate logistic regression was used to analyze the factors influencing turnover intention. A total of 98 questionnaires were distributed and 98 questionnaires were returned, with a recovery rate of 100%. Results The average score of job stress, job burnout and turnover intention were 85.49±5.42, 36.17±3.52 and 14.99±3.32, respectively. There were differences in the scores of work stress among different age, working years, education background and establishment groups (P less then 0.05) . The scores of job burnout among nurses with different working years, education background, professional title, salary and establishment were different (P less then 0.05) ; the scores of turnover intention of nurses in different age, working years, professional title, salary and establishment group were different (P less then 0.05) ; salary, job burnout and occupational pressure were the influencing factors of turnover intention (P less then 0.05) . Conclusion The operating room nurses have high work pressure and job burnout is an important factor leading to high turnover intention.Objective To explore the index system and weight of occupational stress risk assessment for civil aviation air traffic controllers (ATC) . Methods In October 2018, a total of 489 ATC staff from an air traffic administration bureau were selected by cluster sampling. Through ATC questionnaire survey, the basic information, the influencing factors of occupational stress and the degree of occupational stress were understood. Based on the order relation analysis method (GL method) , the influencing factors of ATC occupational stress in civil aviation are evaluated. The fuzzy relation synthesis principle is applied to carry out multi-level fuzzy evaluation on the subordinate degree of occupational stress risk, and the ATC occupational stress risk evaluation system model is established.  https://www.selleckchem.com/products/BIBF1120.html  The weight of each index in the index system is determined, Establish a three-level comprehensive evaluation index system for ATC occupational stress risk, and quantify the occupational stress risk, Each Civil Aviation ATC occupational stress index corresponds to different degree of stress. Results The influence degree of ATC occupational stress from heavy to light is work factor, psychological factor, event factor, management factor, physiological factor, equipment factor and environmental factor (weight value is 0.2652, 0.2265, 0.1832, 0.1253, 0.1154, 0.045 5, 0.038 9 respectively) . Conclusion GL method can be used to comprehensively and quantitatively evaluate the occupational stress risk of Civil Aviation ATC, which may be a feasible way to evaluate the occupational stress risk of Civil Aviation ATC.Objective To investigate the quantitative changes of γδT cells in peripheral blood before and after anti-Brucella treatment in patients with chronic brucellosis. Methods A prospective design was used to 88 patients with chronic brucellosis who were admitted to the Second People's Hospital of Tianjin from September 2012 to April 2018. The patients took anti-brucella drugs, And the changes in the number of γδT cell, CD3(+), CD4(+), CD8(+)T lymphocytes and CD4/8 in peripheral blood before treatment, 6 weeks and 12 weeks after treatment were analyzed. Thirty volunteers were selected as the healthy control group from Tianjin Second People's Hospital employee health checkup in 2014. Results After 6 weeks antibacterial therapy, the counts of CD3(+), CD4(+) and CD8(+)T lymphocytes were significantly lower than before treatment in patients with chronic brucellosis (P less then 0.05) . After 12 weeks antibacterial therapy, the counts of γδT cell, CD3(+), CD4(+) and CD8(+)T lymphocytes were significantly lower than before treatment (P less then 0.05) , but CD4/8 was higher than before treatment in patients with chronic brucellosis (P less then 0.05) . Compared with healthy control group, after 6 weeks antibacterial treatment, the γδT cell count was still significantly higher, but the CD4(+)T lymphocyte count was lower (P less then 0.05) . After 12 weeks treatment, the γδT cell count was still significantly higher than that of the healthy control group (P less then 0.01) . Conclusion γδ T cells, CD4(+), CD8(+) and CD3(+)T lymphocytes may play a role in human body resistance to chronic Brucella infection.
