Abstract:
ObjectiveTo investigate the significance of cerebrospinal fluid(CSF) S-100B protein and vascular endothelial growth factor (VEGF) levels in the pathogenesis of brain injury of viral encephalitis.MethodsForty-two patients with viral encephalitis (viral encephalitis group) and 40 patients with other disease at the corresponding time period(control group) were involved in this study.CSF (routine,biochemistry and cytology) was detected,and the levels of S-100B protein and VEGF in CSF were detected by ABC-ELISA method.ResultsWhite blood cell count was (0-584) × 106/L in viral encephalitis group,and (0-200) × 106/L in control group.The levels of protein and glucose in CSF had no significant difference between two groups (P＞ 0.05),and the level of chloride in CSF in viral encephalitis group was significantly lower than that in control group[ ( 110.10 ± 31.22 ) mmol/L vs.( 123.80 ± 6.32 ) mmol/L ] (P =0.006).In viral encephalitis group,cytological examination showed that mixed type cytological reaction was in 6 cases (14.3％,6/42).The level of S-100B protein in viral encephalitis group [25.04-47.97 (28.37 ± 6.09) ng/L] was significantly higher than that in control group[ 25.04-29.64(26.03 ± 0.90) ng/L ] (t =2.462,P =0.018).The level of VEGF in viral encephalitis group[88.84～143.77(96.24 ± 13.38) ng/L] was significantly higher than that in control group [89.15～96.18 (90.67 ± 1.71 ) ng/L] (t =2.673,P =0.011 ).ConclusionsThe high levels of S-100B protein and VEGF in CSF could support the viral encephalitis diagnosis.Tracking the levels of S-100B protein and VEGF in CSF dynamically have noticeable effect on checking the condition of viral encephalitis patients.
