Abstract:
Objective To investigate the expression of Toll-like receptor 4 ( TLR4 ) and nuclear factor-κB ( NF-κB) in patients with critically severe hand, foot and mouth disease ( HFMD) and to evaluate the effects of esmolol intervention on those patients.Methods Fifty-two hospitalized children with critically severe HFMD in the Intensive Care Unit of Xuzhou Children′s Hospital were enrolled in the study from May 2014 to May 2015 and randomly divided into two groups, represented as group A and group B.Children in the group A were given routine treatment, while those in the group B were treated with esmolol in addition to the routine therapy.Thirty children with common HFMD were selected as disease control, and thirty healthy children were set up as normal control.Differences in the expression of TLR4, NF-κB, TNF-αand IL-6 among all children were comparatively analyzed.The levels of TLR4, NF-κB, TNF-αand IL-6 in children from groups A and B were detected after 24 hours, 72 hours and five days of treatment and the differences betweenthetwogroupswereanalyzed.Results (1)Comparedwiththechildrenfromdiseasecontroland normal control groups, those with critically severe HFMD showed significantly increased expression of TLR4, NF-κB, TNF-αand IL-6 (P<0.01).(2)No significant differences in the expression of TLR4, NF-κB, TNF-αand IL-6 were found between the two subgroups of children with critically severe HFMD before treat-ment (all P>0.05).The expression of TLR4, NF-κB, TNF-αand IL-6 in children from both subgroups were significantly decreased after receiving corresponding treatments for 24 hours, 72 hours and five days (all P<0.05).Compared with the children form group A, those from group B showed significantly decreased expression of NF-κB, TNF-αand IL-6 after 24 and 72 hours of corresponding treatments (all P<0.05).No significant difference in the expression of TLR4 was observed between the two subgroups after 24 and 72 hours of corresponding treatments (P>0.05).No significant differences in those observed indicators were found between the two subgroups after five days of treatments (all P>0.05).Conclusion The TLR4/NF-κB/proinflammatory factor pathway might play an important role in the development of critically severe HFMD.Treatment with esmolol could inhibit the expression of NF-κB, reduce the secretion of inflammatory factors and alleviate the inflammatory reaction during critically severe HFMD.
