RESUMO
BACKGROUND:Pulsed electromagnetic field is a non-invasive and non-radiative treatment method.Clinical use of pulsed electromagnetic fields in the treatment of orthopedic diseases has achieved certain results. OBJECTIVE:To review the current clinical application of the pulsed electromagnetic field in the treatment of orthopedic diseases,providing a scientific theoretical basis for the clinical treatment of orthopedic diseases. METHODS:The first author used a computer to search PubMed,CBM,Cochrane Library,CNKI,and WanFang Data for related studies on the pulsed electromagnetic field in the treatment of orthopedic diseases,using the keywords of"pulsed electromagnetic field,orthopedics,osteoarthritis,osteoporosis,bone healing,electromagnetic navigation"in English and Chinese.For the literature related to the same content,recent publications were selected.A total of 69 articles were selected from the search results for review. RESULTS AND CONCLUSION:Pulsed electromagnetic field has a definite curative effect on fracture healing.It can be used in the treatment of osteomyelitis by antibacterial,bactericidal,anti-inflammatory and promoting bone healing,and can inhibit osteoporosis and its progress.In addition,the treatment of early osteoarthritis,femoral head necrosis and postoperative rehabilitation of late joint replacement through various ways can become a treatment for orthopedic diseases.However,the therapeutic mechanism of the pulsed electromagnetic field for a variety of orthopedic diseases is still unclear,and most of the research is still in the primary stage.In the future,it is still necessary to obtain more reliable evidence from high-quality research and clinical trials to provide a more perfect basis for the clinical treatment of orthopedic diseases.
RESUMO
Objective:To understand the overall development and dynamic change trend of scientific research input-output efficiency of a tertiary hospital in Xinjiang from 2016 to 2021, so as to provide reference and basis for optimizing hospital scientific research configuration and improving scientific research efficiency.Methods:The BCC model of Data Envelopment Analysis (DEA) method is combined with Malmquist index method for analysis and evaluation.Results:Within 6 years, the average value of comprehensive technical efficiency of nursing units has not reached 1.The total factor productivity of nursing units was unstable, showing an alternating rise and fall trend, with a fluctuation range of 0.749~1.140.Conclusions:The overall efficiency of scientific research in clinical departments of hospitals is not high. Hospitals should implement multi-level scientific research evaluation, form a dynamic evaluation system for scientific research, reasonably optimize and supervise the investment and utilization of scientific research resources, improve the scientific research management system, enhance the scientific research awareness of researchers, promote technological progress of researchers, and thereby improve scientific research efficiency.
