Diabetic foot ulcer is one of the severe chronic complications that lead to disability and death of diabetic patients. In order to solve this problem, adjuvant therapy studies of diabetic foot ulcers have increased in recent years. Extracorporeal shock wave therapy is a novel adjuvant therapy that has been approved by the US Food and Drug Administration for diabetic foot ulcers wounds. In this paper, the mechanisms of extracorporeal shock wave therapy for diabetic foot ulcers are described, including wound angiogenesis, wound tissue blood perfusion, nerve regeneration, granulation tissue proliferation, inflammatory response, anti-infection, migration and differentiation of mesenchymal stem cells and endothelial progenitor cells. This study aims to provide a theoretical basis for the clinical application of extracorporeal shock wave therapy in clinical treatment of diabetic foot ulcers.
Wuhan Leishenshan Hospital was built within 12 days during the key period of fighting against coronavirus disease 2019 (COVID-19) in Wuhan. It was a field infectious disease hospital with 1500 beds. Due to the emergency of the epidemic situation, the operation mode of “parallel of construction, acceptance, training and treatment” was employed. During the peak period, nearly 3000 medical workers and 13000 builders worked on the same site. In 67 days, 2 011 patients with COVID-19 were treated. Through the bundle infection prevention and control (IPC) measures, Wuhan Leishenshan Hospital achieved zero infection, zero accident, and low level pollution of SARS-CoV-2 (0.3%) by environment monitoring. The bundle IPC measures of Leishenshan Hospital not only provided prevention and control experience for other field infectious disease hospitals at domestic and abroad during the period of COVID-19, but also put forward ideas and work flow for other medical institutions to deal with emerging infectious diseases.
