ABSTRACT
Objective@#To investigate the situation and influential factors of the job burnout among the nurses in Guangzhou, China.@*Methods@#In April 2017, 166 nurses from 8 hospitals in Guangzhou were surveyed by applying the Maslach Burnout Inventory (MBI) to investigate their Emotion Exhaustion (EE) , Depersonalization (DP) and Personal Accomplishment (PA) , and applying Simplified Coping Style Questionnaire (SCSQ) to examine negative coping style and positive coping style based on group random sampling.@*Results@#The nurses exhibited moderate burnout on both EE and DP, as well as severe burnout on PA. Compared with the nurses in the general hospitals, the nurses in the occupational disease hospital had lower scores on both EE and DP (t=-7.305, -3.442, P<0.01) , and they had higher scores on PA (t=2.597, P<0.05) . The married nurses had higher scores on EE (t=2.988, P<0.01) . The nurses in the disinfection supply department had higher scores on EE and lower scores on PA than the nurses in other departments (t=3.788, -3.990, P<0.01) . There was a significant difference on EE between different working age groups (F=3.225, P<0.01) . 6-10 years and 21-25 years of working age had higher scores on EE. Positive coping was negatively correlated with DP (r=-0.190) , and it positively correlated with PA (r=0.323) . Negative coping was positively correlated with both EE and DP (r=0.389, 0.293) .Hospitals types, negative coping style and positive coping style both entered the regression equation for EE (R2=0.368, P<0.01) and the regression equation for DP (R2=0.199, P<0.01) . Positive coping style and department types entered the regression equation for PA (R2=0.201, P<0.01) .@*Conclusion@#Nurses in Guangzhou got moderate level on both EE and DP, lower level on PA. Hospitals types, department types, marital status, working ages and coping style are all the influential factors of job burnout.
ABSTRACT
Three female workers in a golf club production company in Guangzhou were diagnosed with occupational chronic mild benzene poisoning. Two of the female workers were assessed as Grade 7 disabilities. One female worker showed the symptoms of the decline of whole blood cells for unknown reasons in the later stages of the medical period. The final assessment was a Class 5 disability. The problems in this work ability appraisal include: the injury condition of the patient who has not been stable during the work ability appraisal, and the contradiction between the disability grade and the occupational disease diagnosis conclusion. In order to avoid similar situations, the following recommendations are recommended: after the worker's injury situation is relatively stable, the assessment will be conducted, the employer will actively exercise the right to review and appraisal, and the diagnosis of occupational diseases will be included in the evaluation criteria for disability grade.
ABSTRACT
Objective@#To analyze the results of occupational physical examination for silica dust, benzene and noise-exposed laborer in 2016 in Guangzhou, to provide basis for occupational health supervise.@*Methods@#The data were derived from "occupational disease and health information surveillance system" and the summary data reported by all the occupational physical examination agencies, and analyzed by descriptive epidemiology method.@*Results@#77506 data from 21 agencies of 12 district were collected, and 63 suspected occupational disease were detected, which including 1 silicosis, 8 benzene poisoning, 54 noise deafness.@*Conclusion@#Noise exposure was distributed widely, noise deafness had to be focused on, occupational chronic benzene poisoning and silicosis should be monitored continuously. Small, foreign economy and manufacturing industry should be supervised firstly.
ABSTRACT
Objective@#To analyze the level of immunoglobulin E (IgE) changes with benzene exposure workers.@*Methods@#Firstly, through occupational health monitoring, 68 hospitalized cases were discovered who were suspected chronic benzene poisoning. Secondly, according to the GBZ68-2013《The diagnosis of occupational benzene poisoning》standard diagnosis and indexing, 68 cases were divided into the benzene poisoning group (n= 29) and the benzene exposure group (n=39) . 50 cases of healthy workers without benzene exposure were for the control group. Use the immune luminescence method to detect IgE levels. Thirdly, Case-control study was used, observing IgE changes though the three groups by statistical analysis.@*Results@#Compared with control group, the level of leukocyte、neutrophil and IgE was drop in benzene exposure group with statistically significant (P<0.05) . Compared with benzene exposure group, IgE of benzene poisoning group was rise, with statistically significant (P<0.05) , IgE of mild benzene poisoning group rise the most obvious, with statistically significant (P<0.05) . Compared with benzene exposure group, IgE of moderate benzene poisoning group was drop, without statistically significant (P>0.05) .@*Conclusion@#Benzene occupational exposure can induce immunosuppression, IgE decreases, and reduces immune surveillance. The response of the IgE level in the mild benzene poisoning patients was significantly elevated, whether it is protective response of the body immune function needs to be studied further investigated.
ABSTRACT
This study was aimed to evaluate effects of different production techniques of Shuxue Tongmai (SXTM) capsules for blood coagulation function and thrombosis formation among mice. The observation was made on the clot-ting time, bleeding time and instauration rate of collagen-adrenaline model of mice. The results showed that com-pared with SXTM II and Ⅲ production technique, the SXTM I production technique of the same dosage group can prolong the clotting time of mice significantly (P < 0.05), and increase the instauration rate of collagen-adrenaline model of mice significantly (P< 0.05). There was no significant difference on the bleeding time of mice between the SXTM I production technique of same dosage group and the saline group. It was concluded that the SXTM had an-ticoagulative and antithrombotic effects. And the SXTM I production technique receives better effects.
