He has profound attainments and unique insights on the timing of intervention in hyperbaric oxygen therapy for various diseases. He is good at the treatment of acute and severe hyperbaric oxygen indications such as ischemia, hypoxic encephalopathy, resuscitation of acute brain dysfunction caused by craniocerebral injury, acute vascular embolism syndrome and crush syndrome. Hyperbaric oxygen treatment of carbon monoxide poisoning and its sequelae and sequelae; Acute and chronic brain dysfunction and brain injury sequelae caused by various reasons; Sudden deafness, intractable tinnitus and dizziness; Acute and chronic peripheral circulation disorders (including vasculitis, deep vein thrombosis, diabetic foot, chronic skin ulcer, bedsore, etc.). ); He has accumulated rich experience in the clinical treatment of chronic osteomyelitis, aseptic osteonecrosis and tissue damage and dysfunction caused by various bone and trauma surgical diseases. Research direction: indications of acute, critical and severe hyperbaric oxygen: including treatment of acute ischemia, resuscitation of hypoxic brain dysfunction, acute vascular embolism syndrome and crush syndrome caused by various reasons. In recent years, the mechanism of hyperbaric oxygen in the treatment of acute ischemic and hypoxic diseases has been studied. The first author has published more than 20 academic papers in China Journal of Marine Medicine and Hypertensive Medicine, China Journal of Nuclear Medicine and China Journal of Occupational Diseases. Won the third prize of Shanghai scientific and technological progress once.
