In the context of urbanization and rapid pace of population aging, an increasing number of older adults has moved out of their place of origin. The elderly migrants, who involve in both geographic mobility and population aging, have become an important focus of academic research and social governance. Focusing on the elderly migrants in China, this paper outlines the current status of research on the elderly migrants around the new century, especially in the past decade（2011-2022）, which includes such dimensions as social adaptation and integration, health status and the accessibility and availability of public health services, social security, and social governance. By doing a systematic review of the existing literature, it also elaborates on the limitations of exiting research in terms of research theories, perspectives, and contents. In addition, this paper analyzes the challenges brought by the elderly migrants to the social governance of receiving cities, and reflects on the future academic research and governance strategies. It proposes that localizing theoretical innovation in academic research, improving the top-level design of urban governance, integrating elderly migrants into the governance of receiving cities and improving urban governance planning, as well as enhancing the digital literacy of elderly are necessary in order to improve the well-being of the elderly migrants and enhance their sense of happiness.

BACKGROUND: Polyether ether ketone has the advantages of elastic modulus close to human cortical bone, good ray transmission, chemical stability, and biocompatibility. Polyether ether ketone is expected to be applied in the field of oral implants. However, polyether ether ketone is bioinert and is difficult to integrate with surrounding bone tissue. Therefore, how to improve the surface bioactivity of polyether ether ketone remains a major issue. OBJECTIVE: To analyze the osteogenic and vasogenic effects of polyether ether ketone surface bone forming peptide 1 and polydopamine composite coating. METHODS: Polyether ether ketone titanium sheets were immersed in dopamine solution for 24 hours to prepare polyether ether ketone-polydopamine materials. Polyether ether ketone-polydopamine material was immersed in the bone forming peptide 1 solution for 24 hours to prepare polyether ether ketonepolydopamine-bone forming peptide 1 material. The micromorphology, hydrophilicity, and elemental composition of the material were characterized. Bone marrow mesenchymal stem cells were injected on the surface of polyether ether ketone, polyether ether ketone-polydopamine, and polyether ether ketonepolydopamine-bone forming peptide-1 materials. Cell viability and adhesion status were evaluated by live/dead cell staining and cytoskeleton staining. Cellular osteogenic differentiation ability was detected by alizarin red and osteocalcin immunofluorescence staining. Human umbilical vein endothelial cells were inoculated on the surface of three groups of materials. Cell viability and angiogenesis level were assessed by live/dead cell staining and immunofluorescence staining of cytoskeleton/vascular endothelial growth factor. RESULTS AND CONCLUSION: (1) Under scanning electron microscope, the surface of polyether ether ketone material was smooth; the surface of polyether ether ketone-polydopamine material had uneven deposits, and the surface of polyether ether ketone-polydopamine-bone forming peptide 1 material had small particles protruding. The results of contact angle test showed that the hydrophilicity of polyether ether ketone-polydopamine-bone forming peptide-1 material was better than the other two materials. X-ray photoelectron spectroscopy results showed that bone forming peptide 1 had been successfully modified on the surface of polyether ether ketone material. (2) Live/dead cell staining and cytoskeleton staining exhibited that compared with the other two materials, polyether ether ketone-polydopamine-bone-forming peptide 1 material could improve the viability and adhesion of bone marrow mesenchymal stem cells. Alizarin red and osteocalcin immunofluorescence staining showed that compared with the other two materials, polyether ether ketonepolydopamine-bone forming peptide-1 materials could promote the osteogenic differentiation of bone marrow mesenchymal stem cells. (3) Live/dead cell staining and immunofluorescence staining showed that compared with the other two materials, polyether ether ketone-polydopamine-bone forming peptide 1 material could improve the viability and adhesion of human umbilical vein endothelial cells and the expression of vascular endothelial growth factor protein. (4) The results show that the modification of bone forming peptide 1 and polydopamine composite coating on polyether ether ketone surface can improve the osteogenesis and angiogenesis.
