Objective To study the effects of Xiaoer-Chaigui-Tuire granules in the treatment of mycoplasma pneumoniae pneumonia (MPP). Methods A total of 200 children with mycoplasma pneumoniae pneumonia which conformed to the standard of admission were randomly divided into the control group (n=100) and the treatment group (n=100). The control group were treated with azithromycin, and the treatment group were treated with Xiaoer-Chaigui-Tuire granules combined with azithromycin. The temperature recovery time, cough disappeared time, asthma disappeared time, lungs rale disappeared time of the two groups were observed and compared. The serum IgG, IgM and IgA levels were detected by ELISA and the CD3, CD4, CD8 cell ratio of peripheral blood were detected by flow cytometry. Results The total effect rate of the treatment group was 95.0％ (95/100), significantly higher than 80.0％ (80/100) of the control group (χ2=10.286, P=0.001). The fever disappeared time (2.5 ± 0.3 d vs. 4.2 ± 0.9 d, t=17.004), cough disappeared time (3.0 ± 0.6 d vs. 4.5 ± 0.5 d, t=19.861), asthma disappeared time (3.1 ± 1.1 d vs. 4.0 ± 1.3 d, t=5.046), lungs rale disappeared time (4.2 ± 1.0 d vs. 8.4 ± 1.5 d, t=22.988) and of the treatment group were significantly lower than those of the control group (P<0.01). After treatment, the IgG (9.47 ± 1.63 g/L vs. 7.05 ± 1.46 g/L, t=11.059), IgM (1.87 ± 0.52 g/L vs. 1.53 ± 0.48 g/L, t=4.804) and IgA (1.79 ± 0.61 g/L vs. 1.20 ± 0.53 g/L, t=7.301) of the treatment group were significantly higher than those of the control group (P<0.01). After treatment, the blood CD3 levels (78.83％ ± 5.20 ％ vs. 57.48％ ± 4.09％, t=32.271), CD4 levels (40.27％ ± 3.42％ vs. 30.54％ ± 3.27％, t=20.563) of the treatment group were significantly higher than the control group, and the blood CD8 levels (21.15％ ± 2.90％ vs. 30.14％ ± 3.85％, t=18.651) of the treatment group were significantly lower than the control group (P<0.01). There was no significant difference in the incidence of adverse events between two groups (χ2=0.649, P=0.421). Conclusions The Xiaoer-Chaigui-Tuire granules combined with azithromycin for children with MPP has a good efficacy and low adverse events. They could relieve the clinical symptoms and improve the children's immune function.
