摘要目的 探讨病毒性脑炎患儿血清及脑脊液神经元特异性烯醇化酶(NSE)、S100B蛋白和神经肽Y(NPY)的水平变化及临床意义.方法 检测50例病毒性脑炎患儿(重症20例,轻症30例)及选择同期住院20例凝诊病毒性脑炎儿行腰穿排除中枢神经系统感染者(对照组)的血清和脑脊液NSE、S100B蛋白和NPY水平,并进行对比分析.结果 病毒性脑炎组血清和脑脊液NSE、S100B蛋白和NPY的含量[血清:(18.90±5.50)μg/L,(0.57±0.26)μg/L,(267.3±54.7)μg/L;GSF:(10.45±4.40)μg/L,(0.93±0.53)μg/L,(347.2±60.6)μg/L]均高于对照组[血清:(10.35±2.49)μg/L,(10±0.06)μg/L,(67.8±22.5)μg/L;GSF:(3.96±1.57)μg/L,(0.29±0.18)μg/L,(102.6±38.9)μg/L](P＜0.01),重症组血清和脑脊液NSE、S100B蛋白和NPY的含量[血清:(21.93±5.39)μg/L,(0.71±0.31)μg/L,(32.5±62.8)μg/L;GSF:(13.05±4.41)μg/L,(1.23±0.66)μg/L,(407.3±68.1)μg/L]均高于轻症组[血清:(15.93±4.02)μg/L,(0.42±0.14)μg/L,(234.7±51.2)μg/L;GSF:(8.05±1.77)μg/L,(0.63±0.26)μg/L,(320.2±59.5)μg/L](P<0.01).结论 NSE、S100B蛋白和NPY的检测有助于判断儿童病毒性脑炎的病情和脑损伤程度,可作为评估预后的重要生化指标.

abstractsObjective To study the changes of neuron-specific-enolase (NSE), S100B protein and neuropeptide Y (NPY) levels in serum and cerebrospinal fluid of children with viral encephalitis and their clinical significance. Methods The NSE, S100B protein and NPY levels in the serum and cerebrospinal fluid of 50 children with viral encephalitiswere were measured, and another 20 children without central nervous system infection were selected as controls. Results The NSE, S100B protein and NPY levels in the serum and cerebrospinal fluid of children with viral encephalitis[serum: (18.90 ± 5. 50)μg/L, (0. 57 ±0. 26) μg/L, (267. 3 ± 54. 7 ) μg/L; GSF: ( 10. 45 ± 4. 40) μg/L, (0. 93 ± 0. 53 ) μg/L, (347.2 ± 60. 6) μg/L] were higher than those in control group [serum: ( 10. 35 ± 2. 49 ) μg/L, ( 10 ± 0. 06 ) μg/L, ( 67. 8 ±22.5)μg/L;GSF:(3.96 ± 1.57)μg/L,(0. 29 ±0. 18)μg/L,(102.6 ±38.9) μg/L] ( P <0.01). The levels of serum and CSF NSE S100B protein and NPY in critical patient[serum: (21.93 ±5.39)μg/L,(0.71 ±0. 31)μg/L, (32. 5 ± 62. 8) μg/L;GSF: (13.05 ±4.41)μg/L, (1.23 ± 0. 66) μg/L, (407.3 ±68. 1 ) μg/L] were higher than ordinary patients [serum: ( 15.93 ± 4. 02 ) μg/L, ( 0. 42 ± 0. 14 ) μg/L,(234.7 ±51.2)μ.g/L;GSF:(8.05 ± 1.77) μg/L,(0. 63 ±0.26)μg/L, (320.2 ±59.5) μg/L] ( P <0. 01 ). Conclusion NSE, S100B protein and NPY can be used to evaluate encephalitis condition, brain damage degree and prognosis of viral encephalitis.
