Abstract： The new era has put forward new and higher requirements for innovative talents in terms of their moral qualities, knowledge structure, and professional abilities. In this context, the practice to cultivate innovative talents in science and technology world-wide has presented new trends, including multidisciplinary collaborations, coherent processes, open coordination among education, research and industry sectors, and empowerment through digital transformation. Relying on the advantages of the Chinese Academy of Sciences (CAS) in scientific and technological innovation, University of the Chinese Academy of Sciences (UCAS) is exploring educational laws to cultivate high-quality innovative and entrepreneurial talents, especially leading talents in science and technology, actively searching for a new path and mode of talent cultivation through the integration of research and education, in respect to creating organizational models, reforming curriculum and teaching systems, and improving ideological and political work, and faculty development to achieve its educational goals.

Abstract： The report of the 20th National Congress of the Communist Party of China regards “invigorating China through research and education and developing a strong workforce for the modernization drive” as a special chapter, and particularly emphasizes that “education, science and technology, and human resources are the foundational and strategic pillars for building a modern socialist country in all respects”. The integration of research and education is an important way to achieve the integrated development of education, technology, and talents. This study traced back to the origin and development of the integration of research and education, analyzed three specific manifestations of cross organizational integration of research and education worldwide, reviewed the development process, institutional logic, and main characteristics of University of Chinese Academy of Sciences (UCAS) in cultivating high-level innovative talents through the integration of research and education since the reform and opening up, and finally looked forward to the prospect of UCAS in cultivating top innovative talents through the integration of research and education.

Abstract：目的 利用微流控芯片技术构建易调控、接近在体微环境的体外血脑屏障模型。 方法 微流控芯片体外模型采用上下双培养池结构，由多聚碳酸酯膜分隔，两套流路系统控制流体。细胞采用原代分离纯化的大鼠脑血管内皮细胞和星形胶质细胞，免疫荧光技术进行鉴定，分别按次序注入微流控芯片上下培养池，按1μL/min的流速进行灌注培养，构建体外血脑屏障模型，并对此模型进行鉴定和评价。结果 原代分离纯化得到两种细胞，免疫荧光法鉴定细胞纯度达95%以上。共培养3天紧密连接开始形成，5天达到峰值，超微结构观察显示内皮细胞之间形成紧密连接，且荧光素钠渗透实验和TEER值测量表明屏障形成良好。 结论 成功构建微流控芯片体外血脑屏障模型，可成为一个新的平台应用于药物筛选、神经系统基础等多项研究中。
