Abstract:
Objective To analyse the clinical significance of (IL-5),interleukin-6 (IL-6),interleukin-8 (IL-8),eosinophil cationic protein (ECP),eosinophil (EOS),immunoglobulin E (IgE),vascular endothelial growth factor (VEGF) and its receptor in serum of children with infectious pneumonia.Methods 80 children with infectious pneumonia were enrolled in Lianyungang Maternal and Child Health Hospital from March 2016 to March 2017,and were included in the observation group.According to the pathogen type,these children in the observation group were divided into virus group,mycoplasma infection group and bacterial infection group.At the same time,30 healthy children were selected as the control group.The levels of TNF-α,IL-5,IL-6,IL-8,ECP,VEGF,VEGF-R1 and VEGF-R2 in serum were measured by enzyme-linked immunosorbent assay (ELISA).The levels of EOS in blood were measured by automatic blood cell analyzer and the level of lgE in serum was detected by immunoturbidimetric turbidimetric assay.Results The levels of TNF-α,IL-5,IL-6,IL-8,ECP,VEGF,VEGF-R1,VEGF-R2,EOS and IgE in the blood of the observation group were significantly higher than those in the control group (t=2.325 ～ 3.593,all P＜0.05).The levels of TNF-α,IL-5,IL-6 and IL-8 in the serum of the bacterial infection group were significantly higher than those in the virus group and mycoplasma group (all P＜0.05).The levels of VEGF,VEGF-1 and VEGF-R2 in serum of patients with mycoplasma infection were significantly higher than those in the group of bacterial infection and virus infection (all P＜0.05).Serum IgE levels and the number of peripheral blood EOS in the bacterial infection group,viral infection group and mycoplasma infection group had no significant difference (P＞0.05).Conclusion The serum levels of TNF-α,IL-5,IL-6 and IL-8 can be used as markers for bacterial infectious pneumonia and viral infectious pneumonia and mycoplasma infectious pneumonia.
