基于我国“双一流”建设高校研究生国际化能力的测评数据,利用倾向得分匹配法(PSM),估计了不同国际化方式对研究生国际化能力的影响。研究发现,国外国际化经历中,出国对研究生国际化能力没有显著的影响,而海外留学则显著提升了国际化能力,尤其是对跨文化交际能力的提升最为明显;在地国际化经历中,修读国际化课程和接触外国人均可显著提升研究生国际化能力;总体上,在地国际化比海外留学对学生国际化能力提升程度更大。为提高我国高等教育的国际竞争力,应重视高等教育在地国际化,形成国内国外双循环体系;加强高校国际化课程和师资建设,注重提升国际化综合能力;鼓励学生进行跨文化交流,拓展国际化视野。

“一带一路”沿线国家来华留学教育为高质量推进“一带一路”建设提供重要的人才与智力支撑。对1999-2017年来华学历留学生国别数据进行分析发现,“一带一路”沿线国家来华留学生的快速增长是推动我国成为亚洲最大的留学目的国的主要因素。然而,沿线国家来华留学生的分布不均,增长速度差异较大。其中,南亚、东南亚和中亚国家生源占绝对优势,占比超过80%,在可预见的未来仍将持续增长。根据近期数据进行线性外推,可以预测2025年沿线国家来华留学生将达到31.28万人,其中研究生层次比例将达到40.37%。为更好地服务于“一带一路”建设,未来应建立“‘一带一路’高等教育协作框架”,针对沿线国家来华留学需求创新教育产品和服务,改进留学服务体系和制度环境,保障“一带一路”教育行动的可持续发展。

目的：采用激素（地塞米松，Dexamethasone）制作成兔股骨头坏死（Steroid—induced Femoral Head Necrosis，SIFHN）模型，探讨普拉固（Pravastatin）是否能干预SIFHN中骨细胞凋亡。方法：12～18周龄日本大白兔34只，雌雄不限，体重（2．5±0．6）kg，随机分为3组：对照组（A组）：6只，单纯标准饲料及草料喂养。实验组（B组）：14只，Dexamethasone 2．5mg／kg·d。肌注。干预组（C组）：14只，Dexamethasone2．5mg／kg·d^-1肌注＋普拉固2．5mg／kg·d^-1口服。期间每组均予青霉素80万单位／只，肌注，链霉素1．0g／只，肌注，2次／周，防止感染。分别于6、8、10、12周处死每组兔子各3只，实验开始及处死前均检查血脂、血Prothrombin Time（PT）、tissueplasminogen（t-PA），处死后行光镜下细胞凋亡分析。结果：C组的兔血脂较B均降低（P〈0.05），PT较实验组均降低（P〈0．05），t—PA较B组升高（P〈0．01）。与B组比较，光镜示细胞凋亡分析指数减少（P〈0．01）。结论：地塞米松能在兔体内成功造成股骨头坏死模型，而他汀类药物普拉固能有效干预SIFHN中骨细胞凋亡，其作用机制可能与降脂、抗凝、调控凋亡基因表达等因素有关。

随着全球化的推进,留学生教育发展迅速,来华留学生人数逐年递增。来华留学生教育政策经历了起步、探索、高速增长和转变发展四个阶段。文章基于罗伯特·克朗的系统分析法对政策进行分析,发现来华留学生教育发展存在留学生的入学标准较低、与中国学生空间分隔较大、师资力量薄弱等问题。为促进我国留学生教育的持续健康发展,应关注“一带一路”沿线国家留学生,营造开放包容的制度环境;建立健全来华留学生教育质量保障体系;拓宽奖学金来源渠道,提高奖学金发放质量意识,完善奖学金管理制度。
