摘　　要：目的探讨血清高迁移率族蛋白B1(HMGB1)及和肽素(Copeptin)在脑外伤患者病情严重程度及预后评估中的价值。方法选取脑外伤患者136例,根据28天预后情况分为存活组(110例)和死亡组(26例),以患者入院时格拉斯哥昏迷量表(GCS)评分分为轻度组(45例)、中度组(53例)和重度组(38例),入院7天内有无感染分为感染组(85例)和非感染组(51例)。比较各组入院第1,3,7天血清HMGB1及Copeptin水平变化。应用受试者工作特征(ROC)曲线分析各时间点血清HMGB1及Copeptin水平对脑外伤患者预后的评估价值。Pearson相关分析脑外伤患者血清HMGB-1,Copeptin水平与GCS评分的相关性。结果重度组第1,3,7天血清HMGB1及Copeptin水平均明显高于轻度组和中度组(F_(HMGB1)=4.193,8.274,13.108;F_(Copeptin)=4.718,5.204,9.263,均P<0.05)。感染组第1,3,7天血清HMGB1及Copeptin水平均明显高于非感染组(F_(HMGB1)=5.317,12.604,16.182;t_(Copeptin)=4.986,9.537,15.613,均P<0.05)。死亡组第1,3,7天血清HMGB1及Copeptin水平均明显高于存活组[HMGB1(μg/L):13.62±5.28 vs 5.91±2.15,17.95±7.42 vs 2.85±1.28和23.84±10.37 vs 1.24±0.65,Copeptin(pmol/L):68.37±13.35 vs 32.72±8.14,77.29±17.62 vs 26.43±6.28和84.36±21.28 vs 18.35±4.16,t_(HMGB1)=13.246,18.705,24.348;t_(Copeptin)=11.252,13.396,19.254,均P<0.05]。随时间变化,死亡组血清HMGB1及Copeptin水平呈升高趋势(P<0.05),而生存组呈下降趋势(P<0.05)。死亡组入院GCS评分明显低于存活组(4.25±1.06 vs 11.36±2.53,t=9.372,P<0.05)。ROC曲线显示,第3天血清HMGB1[AUC(95%CI):0.913(0.851~0.975)]及Copeptin[AUC(95%CI):0.875(0.814~0.934)]水平预测脑外伤患者死亡的最佳截值取11.46μg/L和50.28 pmol/L时,其敏感度和特异度最好,分别为91.6%,86.5%和88.5%,83.0%。结论 HMGB1及Copeptin水平变化与脑外伤患者的病情严重程度及预后相关,第3天HMGB1及Copeptin最佳截值为11.46μg/L和50.28 pmol/L的患者预后较差。Objective To investigate the value of serum high mobility group protein B1 （HMGB1） and peptide （Cope＇ptin） in the assessment of the severity and prognosis of patients with traumatic brain injury. Methods One hundred and thirty-six cases of patients with traumatic brain injury were selected and divided into survival group （110 cases） and death group （26 cases） according to the 28 days prognosis. Glasgow Coma Scale （GCS） in patients on admission were divided into mild group （45 cases） ,moderate group （53 cases） and severe group （38 cases） ,within 7 days after admission without infection were di- vided into infection group （85 cases） and non infection group （51 cases）. The changes of serum HMGB1 and Copeptin levels were compared in each group for first,third and seventh days. The evaluation val＇ue of serum HMGB1 and Copeptin levels at each time point were used to evaluate the prognosis of patients with traumatic brain injury （ROC） curve. Pearson correlation analysis of serum HMGB1 and Copeptin levels in patients with traumatic brain injury and the correlation of GCS score. Re- salts The levels of serum HMGB1 and Copeptin in the severe group were significantly higher than those in the mild group and the moderate group on first, third and seventh days （t .MGB1 = 5. 317,12. 604,16. 182 ; tCopep,in ： 4. 986,9. 537,15. 613, all P d0.05）. The level of serum HMGB1 and Copeptin in the infected group were significantly higher than those in the non in- fection group on first, third and seventh days （FHMGB1 = 4. 193,8. 274,13. 108 ; FCopeptin= 4.718,5. 204,9.263, all P〈 0.055 ）. The levels of serum HMGB1 and Copeptin in the death group were significantly higher than those in the survival group on first,third and seventh days [HMGBI（μg/L） ：13.62±5.28 vs 5.91±2.15,17.95±7.42 vs 2.85±1.28 and 23.84±10.37 vs 1.24±0.65,Copeptin （pmol/L） ：68.37± 13.35 vs 32.72±8.14,77. 29±17.62 vs 26.43±6.28 and 84.36±21.28 vs 18.35±4.16,tHMGB1 =13. 246,18. 705,24.
