In the process of pneumonia induced by MDR PA infection, the anti-inflammatory cytokine IL-10 in the Model group increased from the early stage and continued to increase until it reached a peak in the later stage, which was consistent with the report that the expression of IL-10 was later than proinflammatory cytokines in the mice challenged by LPS [46]. The gene discussed is IL10; the disease is susceptibility to pneumonia measurement.
