ABSTRACT
Objective:To explore ways and methods for public mental health intervention during the COVID-19 epidemic.Methods:A comprehensive literature review was conducted. Mental healthcare publicity materials posted by over 100 Chinese hospitals in multiple media (till February 24, 2020) were also systematically collected and analyzed.Results:Firstly, anxiety and fear were the most common mental health problems among people during the epidemic. Secondly, to achieve better outcomes, mental health intervention should be provided according to the type of service clients. Thirdly, new media can facilitate the transmission of mental healthcare knowledge, but the limitation is that it can not approach older adults who have limited access to new media. It is therefore essential to strengthen the mental health knowledge transmission to older adults.Conclusions:Mental health intervention is effective when it is provided according to the type of service clients during the COVID-19 epidemic.
ABSTRACT
BACKGROUND: Bone exposed wounds are frequently required to deal with in orthopaedic surgeries, involving the treatment of open fractures, bone tumors, osteomyelitis, and many other diseases, in which the defect of soft tissue caused by open fractures is the most difficult to deal with. Conventional debridement or negative pressure closed drainage technology is difficult to make bone exposed wounds heal, and the process is extremely cumbersome, during which,patients suffer a lot of pain.OBJECTIVE: To evaluate the advantages and disadvantages of the various types of dressings, and review the application of new hydrogel dressing in bone exposed wounds based on its advantages, such as keeping wound environment moisture, restoring skin physical barrier, contributing to routine dressing change.METHODS: A computer-based online retrieval of PubMed and CNKI databases was performed to search papers published between 2000 and 2016 using the key words hydrogel dressing, bone exposed wound, traditional wound dressing, antibiotic in English and Chinese, respectively. A total of 55 papers suitable for final analysis from the application of traditional and new dressings in bone tissue engineering were reviewed.RESULTS AND CONCLUSION: The treatment of bone exposed wounds involves the treatment of many diseases, such as open fractures, bone tumors, osteomyelitis, which is still an orthopedic problem to solve. The novel hydrogel dressings with unique advantages are able to provide better plans for bone exposed wounds, and the use of these dressings solves the regeneration and repair of exposed bone, and improves the infection of antibiosis. In addition, the gel dressings currently have become a hot spot of research because of the characteristics of sustained-release.
