Objective To investigate the current situation of long-term care needs of the elderly with home-based disabil-ity in Beiliu City,and provide data support for the development of Internet plus care services in Beiliu City.Methods A ques-tionnaire survey method was used to design and distribute a survey questionnaire titled"Survey Questionnaire on Home Care Serv-ice Needs of Disabled Elderly People",to investigate the nursing service methods and home care needs of disabled elderly people in Beiliu City.Results Disabled elderly people mainly choose home-based nursing services,with a high demand for basic care,comfortable care,rehabilitation care,psychological care,and other aspects.Conclusion Home care is of great significance for improving the quality of life of disabled elderly people,and requires policy support such as medical insurance to promote the sup-ply of nursing services and meet the care needs of disabled elderly people.

Dental resin composites (DRCs) are popular materials for repairing caries or dental defect, requiring excellent properties to cope with the complex oral environment. Filler/resin interface interaction has a significant impact on the physicochemical/biological properties and service life of DRCs. Various chemical and physical modification methods on filler/resin interface have been introduced and studied, and the physical micromechanical interlocking caused by the modification of fillers morphology and structure is a promising method. This paper firstly introduces the composition and development of DRCs, then reviews the chemical and physical modification methods of the filler/resin interface, mainly discusses the interface micromechanical interlocking structures and their enhancement mechanism for DRCs, finally give a summary on the existing problems and development potential.
