The therapeutic effect on fever and cough was obviously better in the control group (P <0.01). The main and secondary symptoms and signs were more obviously improved in the treatment group than in the control group (P <0.01). Commpared with the control group, scores for main and secondary symptoms and signs decreased more in the treatment group (P <0.01). Patients' main and secondary symptoms and signs were more obviously improved (P <0.05).</p><p><b>CONCLUSIONS</b>Zhifei Mixture combined Western drugs could significantly improve main and secondary symptoms and signs of mycoplasma pneumonia children patients.
