ABSTRACT
OBJECTIVE: To evaluate the effects of occupational health intervention measurements on occupational health of pre-employment workers. METHODS: Four hundred and three pre-employment workers from different types of occupations and enterprises of different industries in Urumqi from October 2013 to December 2014 were selected as the study objects.Health education intervention measurements including occupational health knowledge,occupational protection theory and practical operations were carried out through expert lectures, distributing promotional materials, on-site or network consulting and other means,which was performed twice per month for over 10 times. A questionnaire survey was performed before and after the intervention on occupational disease prevention and treatment knowledge,attitude and occupational health education demands among the workers. RESULTS: Among the 403 study subjects,the total awareness rate of occupational disease prevention and treatment knowledge after intervention was higher than that before intervention( 88. 09% vs 49. 63%,P < 0. 01). The total positive rate of occupational disease prevention and treatment attitude was higher than that before the intervention( 96. 03% vs 62. 28%,P < 0. 01). The total demand rate of occupational health education was increased compared to that before the intervention( 84. 62% vs 48. 64%,P < 0. 01). CONCLUSION: The occupational health promotion for pre-employment workers can increase the workers 'awareness of occupational disease knowledge,understand and identify occupational disease hazards,and strengthen their consciousness of self protection. It is one of the effective ways to protect the employees' physical and mental health and avoid occupational hazards.
ABSTRACT
Objective To determine whether homocysteine(Hcy)and monosodium glutamate (MSG)could lead to animal model of hypertensive disorder complicating pregnancy and its mechanism. Methods Female adult Wistar rats were randomly divided into 4 groups:pregnant control group(PN), pregnant Hcy group(PH),pregnant glutamic acid group(PG)and pregnant Hcy and glutamie acid group (PHG).The rats of each group were injected with Hey 200 mg/kg or physiological saline every day intraperitoneally and with MSG or 0.9% saline every other day via Hcy injection from the 10th day to the 20th day of pregnancy.The blood pressure,urine protein,function of liver and kidney,weight of placenta, length and weight of fetus were all measured.The histological change of the pallium and the change of behavior of pregnant rats were also observed.Results(1)The blood pressure in PH[(107?8)mm Hg, 1 mm Hg=0.133 kPa],and PHG group [(109?10)mm Hg] after the treatment increased significantly compared with those in other groups from the 12 th day after pregnancy(P
