Methods:RT-PCR and enzyme-linked immunosorbent assay were used to measure the serum EOF and NGF expression levels of patients with limb fracture and brain trauma injurry after 1 d,3 d,7 d,14 d and the relationship between them was analyzed.The level was compared among the simple fracture group,traumatic brain injury group and the normal control group,with 40 cases in each group.Results:The serum NGF levels were significantly different among three groups. Senun NGF,EGF mKNA and protein levels gradually decreased with the increasing injury time in the limb fracture combined with brain injury gnmp,traumatic brain injury group,the simple fracture group and the health control group(P【0.05).Conclusions:The serum of NGF.EGF levels significandy increased when limb fracture combined with brain injury,so EGF and NGF may be involved in the process of fracture healing.展开更多
