Abstract: Objectives　To summarize the application of Guidelines for the Management of Community-Acquired Pneumonia  (CAP) (2013 edition) in the diagnosis and treatment of children with CAP. Methods　The clinical features of 209 children with non-severe CAP at different age stages were retrospectively analyzed. The curative effect of azythromycin was summarized which was used as first-line antibiotics in the CAP treatment. Results　In 209 CAP children, the onset of 94 children was occurred in spring and summer and 115 occurred in autumn and winter. The white blood cell counts (WBC) in 51 CAP children (24.4%) were more than 10.0×109/L and absolute neutrophil counts (ANC) in 91 CAP children (43.5%) were more than 5.0×109/L. C-reactive protein levels in 199 CAP children (95.7%) were increased and MP-IgM showed positive in 94 CAP children (45.0%). 173 CAP children (82.8%) presented unilateral inflammatory lesions in chest X-ray, and the right side was predominant. There was no difference in onset season among different age groups (P>0.05). However, the percentage of WBC ≥ 10×109/L among different age groups were significantly different (P=0.002) and the percentage of WBC ≥ 10×109/L was highest in infants and young children group. The proportion of onset in spring and summer was significantly higher in MP-IgM positive group than that in MP-IgM negative group (P<0.01). The total effective rate of azithromycin used as first-line antibiotics was 98.1% (205/209), and there was no significant difference in total effective rate of azithromycin between MP and non-MP pneumonia groups. Conclusions 　The Guidelines for the Management of CAP (2013 edition) have a reference value in the diagnosis and treatment of CAP in our region where the CAP in children has some different features.
