OBJECTIVE: Duplicating the classical alcoholic hepatic injury model, to provide an ideal animal model for research on prevention and treatment of hepatic injury. METHODS: According to the prescription of Lieber-DeCarli, the same calorie fluid animal feed, which contained ethanol or non-ethanol, was prepared. Twenty-three rats were divided into normal control group (n=5), control liquid diet group (n=9), ethanol liquid diet group (n=9). Rats in the normal control group were fed normal diet, and rats in the control liquid diet group and ethanol liquid diet group were fed the corresponding diet for eight weeks. The pathologic changes of hepatic tissue were observed. The activities of the serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST), the liver tissue gamma-glutamyltransferase (gamma-GT), the content of triglyceride (TG), and the lipid peroxidation by-products were assayed. RESULTS: Compared to the normal control and the control liquid diet groups, the activities of ALT, AST, and gamma-GT, and the lipid peroxidation by-products increased significantly in the ethanol liquid diet group. The pathological changes of cellular swelling and fatty degeneration in the ethanol liquid diet group were severe. CONCLUSION: Alcoholic hepatic injury model can be successfully duplicated by Lieber-DeCarli prescription.

Objective: To investigate the occupational health survey of 1-brominepropane (1-BP) enterprises and understand the impact of 1-BP on the health of occupational exposure population. Methods: The occupational health data of 15 1-BP workers were collected from 3 time nodes in 0 months, June and December, and the effects of occupational exposure to 1-BP on health were analyzed. Results: In the workplace with pure 1-BP, the mean air concentration in the workplace was 26.8 mg/m³, and the personal contact level was 29.7 to 63.4 mg/m³. The occupational health monitoring data showed that white blood cell count (WBC) , red blood cell count (RBC) , aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were compared in 0 months, June, and 12 months, the difference was statistically significant (P<0.05) . Conclusion During the 12 months observation period, the occupational exposure to 1-BP caused the number of peripheral blood erythrocyte and leukocyte count and the level of alanine transaminase in the workers, but it did not exceed the normal reference range.

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. 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 ( P<0.01) . Multi-factor analysis of the laser effect on the lens showed that the main effect between groups, between the observation point were statistically significant ( P<0.05) , but no statistical significance in the interaction between group×observation points ( P>0.05) . 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.
