摘要
Dear editor,It is with great interest that we read the article“Relationship of calcitonin gene-related peptide with disease progression and prognosis of patients with severe traumatic brain injury”(Chen et al.,2018).In this study,the authors evaluated 121 patients who were divided into mild/moderate traumatic brain injury(TBI)(n=61),severe TBI(n=35)and control(n=25)groups,and measured serum levels of calcitonin gene-related peptide(CGRP)and serum endothelin-1(ET-1).They found that low levels of CGRP and high levels of ET-1 were associated with high mortality at 6 months.Identification of morphological abnormalities on CT scans is very important for evaluating patients with TBI because different diagnoses are made based on different imaging findings(Maas et al.,2005).
