Traumatic brain injury has high morbidity,disability and mortality ; worldwide, more than 50 million new cases , mainly low and middle-income countries.The annual incidence of craniocerebral trauma in China is (55 - 64) / 100000 , with 770 - 890 thousand new cases,causing nearly 100000 deaths and hundreds of thousands of disabilities , which is a serious public safety problem .Injury mechanisms after traumatic brain injury include primary and secondary brain injury and have a lack of effective treatment .Brain edema is one of the main mechanisms of secondary brain injury and one factor in the prognosis of traumatic brain injury .In recent years , the Sur1-Trpm4 channel was found to play an important role in the onset of brain edema , with increased expression in traumatic brain injury , ischemic stroke , and ischemic and hypoxic encephalopathy , and the specific inhibitor glibenclamide can reduce brain edema .A clinical study of glibenclamide in the treatment of brain edema after traumatic brain injury to evaluate whether glibenclamide treatment can improve the blood NSE and S100β levels of severe traumatic brain injury , so order to explore the efficacy and adverse effects of this drug in the treatment of traumatic brain injury .
