DNA damage of germ cell of rat induced by nitrotoluene chemicals

dinitrotoluene(2,4 DNT), 2,6 dinitrotoluene(2,6 DNT) and 4 nitrotoluene(4 NT) are typical pollutants in the Songhua River of Northeast China. Sertoli/germ cell cocultures and single cell gel electrophoresis(SCGE) are applied to investigate whether they have genotoxicity on DNA damage of germ cell of Kunming male rat. The results showed that all three nitrotoluene compounds tested could induce DNA single strand breaks of the germ cell. A significant relationship is found between logarithm dose and the degree of DNA damage, which implies that 2,4 DNT, 2,6 DNT and 4 NT have genotoxicity and can induce the germ cell DNA strand to break in vitro.

“健康丝绸之路”与高校卫生管理国际化人才培养

人才是第一资源,高校卫生管理国际化人才培养是“健康丝绸之路”建设重要的基础性工作。卫生管理国际化人才的不足已经成为制约中国医药卫生事业“走出去”面临的主要现实问题。文章认为高校卫生管理国际化人才培养存在卫生管理专业师生的国际化意识不强、课程教学不符合卫生管理国际化人才培养的要求、学生出国留学和海外实践的机会较少、产教协同育人的模式没有真正形成、高校卫生事业管理教育质量缺乏国际认证等困境,并针对存在的困境提出了相应的对策建议。
