RESUMO

Objective To investigate the change of serum Nogo-A protein in patients with acute closed brain injury, and explore its relationship with the severity of neuronal damage and prognosis. Methods Thirty-one patients with acute closed brain injury were enrolled. Venous blood samples (2 mL) were obtained 1, 3 and 5 d after injury. Serum concentrations of Nogo-A protein were determined by ELISA. Patients were divided into mild (n =7), moderate (n = 10) and severe (n = 14) injury groups according to Glasgow coma score (GCS), and were divided into favorable prognosis (n = 23) and poor prognosis (n = 8) groups according to Glasgow outcome score (GOS). Another 20 healthy adults were served as controls. Results The mass concentrations of serum Nogo-A protein in mild, moderate and severe injury groups 1, 3, 5 d after injury were significantly higher than those in control group (P < 0.01), and the mass concentrations of serum Nogo-A protein in moderate and severe injury groups 1, 3, 5 d after injury were significantly higher than those in mild injury group (P <0.05, P <0.01). The mass concentrations of serum Nogo-A protein 1, 3, 5 d after injury were significantly higher in poor prognosis group than those in favourable prognosis group (P < 0.01). Conclusion Serum Nogo-A protein level significantly increases after brain injury, and is related to the degree of injury and prognosis.

RESUMO

Post-traumatic cerebral infarction(PTCI)is a known severe complication of craniocerebral trauma. It often aggravates the disease of patients and increases mortality. The incidence of PTCI varies from 1.9%to 23%.In recent years. the incidence of PTCI has increased slightly with the continuous advancement of checkup means and awareness. Howeuer. because of the simultaneous existence of primary brain injury and various secondary brain damage, the early diagnosis and treatment of PTCI are difficult .This article reviews the clinical types, onset time, causes, clinical risk factors, diagnosis and treatment of PTCI.
