Cell suspension and level of IL-17 in bronchoalveolar lavage fluid (BALF) of children with labor pneumonia combined with mycoplasma pneumonia and its clinical significance / 中国内镜杂志

ABSTRACT

Objective To explore cell suspension and level of IL-17 in bronchoalveolar lavage fluid (BALF) of children with labor pneumonia combined with mycoplasma pneumonia and its clinical significance. Methods 87 children with labor pneumonia who had been done BAL were divided into CPIS ≥ 6 group and CPIS 0.05). The percentage of columnar epithelial cells in CPIS < 6 group were higher than CPIS ≥ 6, how-ever, macrophagocyte was lower ( < 0.05). The percentage of neutrophils are related with both MP-DNA ( = 0.48,= 0.000) and IL-17 ( =0.49, =0.000). Conclusions The composition of BALF is more appropriate to react the circumstance of lobar pneumonia. When lobar pneumonia occurs, columnar epithelial cells are damaged, macrophagocyte gathered to participate in the inflammatory response. In Mycoplasma pneumonia infection group, IL-17 raises neutrophils to resist infection, NE%in BALF can indirectly reflect the mycoplasma infection degree.
