目的探讨血清寡聚化结构域样受体蛋白3(NLRP3)、淀粉样蛋白A(SAA)及核转录因子(NFκB)在颅脑损伤术后颅脑感染中的诊断价值。方法选择2020年6月至2022年6月江苏省如皋市人民医院接诊的70例颅脑损伤患者为研究对象,根据感染情况将感染者设为感染组(n=19),未感染者设为对照组(n=51),分析血清NLRP3、SAA及NFκB在颅脑损伤术后颅脑感染中的诊断价值。结果感染组患者血清NLRP3、SAA及NFκB水平显著高于对照组,差异有统计学意义(P<0.05);NLRP3、SAA及NFκB水平:轻度感染<中度感染<重度感染,差异有统计学意义(P<0.05);预后不良组患者血清NLRP3、SAA及NFκB水平显著高于预后良好组,差异有统计学意义(P<0.05);ROC结果显示,血清NLRP3预测颅脑损伤术后颅脑感染的AUC为0.634,灵敏度为63.43%,特异度为67.40%,截断值为114.02 pg/mL;血清SAA预测颅脑损伤术后颅脑感染的AUC为0.715,灵敏度73.50%,特异度为69.00%,截断值为30.99 mg/L;血清NFκB预测颅脑损伤术后颅脑感染的AUC为0.914,灵敏度为81.40%,特异度为70.00%,截断值为38.27μg/mL,联合检测较单独检测特异度、准确度更高(P<0.05)。结论血清NLRP3、SAA及NFκB在颅脑损伤术后颅脑感染患者中均异常高表达,且三指标联合检测颅脑损伤术后颅脑感染诊断效能更高,临床应用价值高。
