| 目的 探讨中性粒细胞CD64、CD11b在儿童化脓性脑膜炎早期诊断中的价值。 方法 选取35例化脓性脑膜炎患儿作为观察组,儿童保健门诊行健康体检的30例儿童作为对照组,比较两组患者治疗前后中性粒细胞CD64、CD11b表达情况,绘制CD64、CD11b诊断儿童化脓性脑膜炎的ROC曲线,确定最佳阀值后计算两者诊断化脓性脑膜炎的敏感度和特异度。 结果 观察组患者治疗后CD64与CD11b表达水平显著低于治疗前,差异有统计学意义(P<0.05);观察组患者治疗前及治疗后CD64与CD11b表达水平均显著高于对照组,差异有统计学意义(P<0.05);CD64与CD11b ROC曲线下面积均>0.5,且因CD64 ROC曲线下面积>CD11b ROC曲线下面积,CD64诊断效能>CD11b;CD64诊断化脓性脑膜炎敏感度和特异度均优于CD11b,差异有统计学意义(P<0.05)。 结论 中性粒细胞CD64、CD11b表达情况可作为早期诊断儿童化脓性脑膜炎的参考指标,其中CD64诊断效能、敏感度和特异度更高。 |

| Objective To explore the values of neutrophil CD64, CD11b in the early diagnosis of bacterial meningitis in children. Methods Thirty-five cases of children with bacterial meningitis were researched as the observation group, and 30 cases who underwent physical examination as the control group. The expression of CD64, CD11b was compared, the ROC curves of CD64, CD11b for the patients with bacterial meningitis were drawn, and after the best threshold calculation both the sensitivity of the diagnosis of suppurative meningitis and specific degrees were researched. Results The levels of CD64, CD11b posttreatment in the observation group were lower than those prior to treatment(P<0.05); the levels of CD64, CD11b posttreatment in the observation group were lower than those in the control group(P<0.05); the area under ROC curve for CD64, CD11b was higher than 0.5; the sensitivity and specificity for CD64 were better than those for CD11b(P<0.05). Conclusion The values of early diagnosis for the patients with bacterial meningitis by neutrophil CD64, CD11b are good, and CD64 has better sensitivity and specificity. |
