Abstract
Objective To investigate the diagnostic value of nuron specific enolase（ NSE）,S100βprotein,glial fibrillary acidic protein（ GFAP）and myelin basic protein（ MBP）in patients with early brain contusion and laceration. Methods One hundred and twelve cases with brain contusion and laceration diagnosed by CT or MRI were selected as our subjects who hospitalized Harrison international peace hospital from Apr. 2012 to Jul. 2013. Of them,68 cases with mild head injury were served as mild group and 44 cases of severe traumatic brain injury were served as severe group. And 83 healthy people without lung disease and nervous system diseases were served as control group. Electro chemiluminescence assay and ELISA methods were used to measure the level of NSE,S100β,GFAP,MBP. Results the level of serum NSE,S100β protein,GFAP and MBP in mild group were（18. 14 ± 6. 83）,（0. 92 ± 0. 45）,（0. 78 ± 0. 37））（4. 37 ± 1. 84）μg/ L,respectively, and（32. 11 ± 12. 48）,（1. 58 ± 0. 94）,（4. 26 ± 1. 96）,（14. 72 ± 6. 77）μg/ L,respectively in severe group, and（8. 94 ± 3. 49）,（0. 12 ± 0. 08）,（0. 13 ± 0. 09）,（1. 98 ± 0. 89）μg/ L,respectively in control group. There were significant differences among three groups（ F = 137. 520,120. 083,283. 727,205. 569 respectively;P〈 0. 01）. All indexes were different between control and mild groups（ q = 10. 599,13. 296,5. 881,6. 018;P〈 0. 01）,as well as between the mild and severe groups（q = 13. 600,9. 249,26. 639,22. 029;P 〈 0. 01）,and between control and severe group（q = 23. 408,21. 258,32. 797,28. 134;P 〈 0. 01）. Conclusion The level of serum NSE,S100β,GFAP,MBP can be used as early indicators of brain injury secondary diagnosis and secondary index for evaluating damage degree.
