ABSTRACT
Objective@#To analyze the epidemiological characteristics of HIV/AIDS infected students in Shandong Province, to provide a basis for the prevention and control of AIDS transmission in the student population.@*Methods@#All 863 HIV/AIDS students cases during 2010-2019 were collected in Shandong Province. Epidemiological characteristics was described and the trends in the 10 years since 2010 was analyzed.@*Results@#These 863 HIV/AIDS students were mainly transmitted through homosexual sex (763 cases, 88.41%), and the samples were mainly from voluntary consultation testing (433 cases, 50.17%). From 2010 to 2019, the proportion of student cases in the total number of cases showed an increasing trend ( χ 2 trend =30.21, P <0.01). Among them, the proportion of homosexual transmission cases increased year by year ( χ 2 trend =6.35, P =0.01), the proportion of cases aged 18-22 years increased year by year ( χ 2 trend =6.10, P =0.01), the proportion of cases with college degree or above increased year by year ( χ 2 trend =4.26, P =0.04). At present, voluntary consultation testing were the main source.There was no significant difference between the years of sample sources ( χ 2 trend =2.97, P =0.09).@*Conclusion@#The report number of students in Shandong Province are on the rise in recent years, especially those infected by same sex transmission, mainly with high education background, which calls for targeted strategies and intervention measures.
ABSTRACT
Hepatic fibrosis in rat induced by intraperitoneal injection of dimethylnitroamine (DMN) was traeted by RNA (4 mg ? kg-1) and CoQ10(2. 5 mg ? kg-1) ,seperately. Normal and pathological groups were compared. In 30, 60 and 90 days treatment, rats were killed for ul-trastructural examination and measurement of serum enzymology, serum amino acids and the quantity of collagenous fibers. The results indicated that, in RNA-treated and CoQ10 treated groups, Aspartate aminotransferase (AST) and Y-glutamyl-transpeptidase(?-GT) were normal, the ratio of albunm to globulin (A/G) had significantly difference compared with controlgroup. In RNA-treated group,L-Alanine:2-Ox-oglutarate Aminotransferase(ALT), monoamine oxidase (MAO) and N-acetyl-?-glucosaminidase (NAG) decreased evidently, serum amino acids increased slightly. Ultrastructural and microscopical examination showed the degree of hepa-tocytic necrosis degeneration and the quantity of collagenous fibers in RNA-treated group were rather mild. It appeared that there were protection effects of RNA on liver enzymology and hepaticfibrosis.
