Changes of MCP-1,FKN,and related cytokines in the serum and cerebrospinal fluid in children with epidemic encephalitis B

摘要

Objective: To explore the changes of MCP-1, FKN, and related cytokines in the serum and cerebrospinal fluid (CSF) in children with epidemic encephalitis B. Methods: A total of 40 children with epidemic encephalitis B who were admitted in our hospital from June, 2014 to June, 2017 were included in the study and divided into the severe group (n=15) and general group (n=25) according to the severity group. Moreover, 20 children who were suffered from oblique inguinal hernia, perineal adhesion, and cryptorchidism were served as the control group. The serum and CSF specimens were collected 24 h after admission and during the recovery period in children with epidemic encephalitis B. The serum specimen was collected 24 h after admission in the control group, and CSF specimen was collected during the lumbar puncture. ELISA was used to detect CMP-1, FKN, IL-1β, IL-18, and TNF-α levels in the serum and CSF. CMP-1, FKN, IL-1β, IL-18, and TNF-α levels in children with epidemic encephalitis B on the day after admission and 2-3 weeks after admission and in the control group were compared. The changes of CMP-1, FKN, IL-1β, IL-18, and TNF-α in children with severe and general epidemic encephalitis B were observed. Results: CMP-1 and FKN levels in the serum and CSF in children with epidemic encephalitis B in the critical stage were significantly higher than those in the recovery stage and in the control group. The serum CMP-1 and FKN levels in children with epidemic encephalitis B during the recovery stage were not significantly different from those in the control group, while CMP-1 and FKN levels in CSF were significantly higher than those in the control group. CMP-1 and FKN levels in the serum and CSF in children with severe epidemic encephalitis B were significantly higher than those in the general group. IL-1β, TNF-α, and IL-18 levels in the serum and CSF in children with epidemic encephalitis B during the critical stage were significantly higher than those during the recovery stage and in the control group. IL-1β, TNF-α, and IL-18 levels in the serum and CSF in children with epidemic encephalitis B during the recovery stage were significantly higher than those in the control group. IL-1β, TNF-α, and IL-18 levels in the serum and CSF in children with severe epidemic encephalitis B were significantly higher than those in the general group. Conclusions: CMP-1, FKN, IL-1β, TNF-α, and IL-18 levels in the serum and CSF in children with epidemic encephalitis B are correlated with the severity degree, detection of which can contribute to estimate the clinical typing and condition change of epidemic encephalitis.
