摘要 目的 探讨中性粒细胞CD64及降钙素原(PCT)预测创伤性脑损伤(TBI)患者预后的价值。 方法 选取海口市120急救中心收治的TBI患者162例,根据28 d预后情况分成存活组(n=128)和死亡组(n=34),根据格拉斯哥昏迷评分(GCS)分为轻度组(n=106,9分≤GCS≤15分)和重度组(n=56,3分≤GCS≤8分)。比较各组第1、3、5天中性粒细胞CD64及PCT水平变化。应用受试者工作特征(ROC)曲线分析中性粒细胞CD64及PCT水平预测TBI患者预后的价值。采用Pearson相关分析TBI患者中性粒细胞CD64及PCT与GCS评分的相关性。 结果 死亡组第1、3、5天中性粒细胞CD64(4.15±1.50 vs. 2.40±0.85,6.63±2.10 vs. 3.25±0.96,8.14±2.70 vs. 3.40±0.92)及PCT水平(ng/mL:1.40±0.73 vs. 0.34±0.26,2.35±1.28 vs. 0.64±0.38,5.42±2.16 vs. 0.58±0.34)均明显高于存活组(P<0.05),且死亡组中性粒细胞CD64及PCT水平随时间呈升高趋势(P<0.05)。重度组第1、3、5天中性粒细胞CD64(3.90±1.42 vs. 2.82±0.94,6.12±1.85 vs. 3.60±0.98,7.86±2.64 vs. 3.53±0.87)及PCT水平(ng/mL:1.27±0.65 vs. 0.50±0.32,2.04±1.25 vs. 0.82±0.45,5.16±1.97 vs. 0.73±0.38)均明显高于轻度组(P<0.05),且重度组中性粒细胞CD64及PCT水平随时间呈升高趋势(P<0.05)。ROC曲线显示,第3天中性粒细胞CD64及PCT两项联合预测TBI患者死亡的AUC最大(0.924, 95%CI0.860~0.972),其敏感度和特异度为92.8%和87.2%。相关分析显示,死亡组中性粒细胞CD64及PCT与GCS评分呈负相关(r=-0.752、-0.817,P<0.01),中性粒细胞CD64与PCT呈正相关(r=0.684,P<0.01)。 结论 中性粒细胞CD64及PCT与TBI患者的病情严重程度相关,第3天两项联合对预测TBI患者预后的价值较高。
