Methods Children (224 cases) with RSV induced bronchiolitis in Huaian Hospital Affiliated to Xuzhou Medical University from February 2018 to October 2019 were randomly divided into control group and observation group, with 112 cases in each group. Children in the control group were given Interferon α -2b injection, 1 000 IU/m2 intramuscular injection, once daily. Children over 1 year old in the observation group were given Montelukast Sodium Chewable Tablets on the basis of control group, 5 mg/time, once daily, children under 1 year old were given Montelukast Sodium Oral Granules in warm water, 4 mg/time, once daily. Both groups were treated continuously for 3 d. The clinical efficacy and improvement of clinical symptoms in two groups were observed, and the levels of lymphocyte subsets, IL-4, and IFN-γ before and after treatment were compared. Results After treatment, the total effective rate was 92.9% in the observation group, which was significantly higher than 77.7% in the control group (P<0.05). After treatment, the time of dyspnea, lung rale, cough, suffocation disappearance, and hospitalization in the observation group were significantly shorter than those in the control group (P<0.05). After treatment, the proportion of Th1 cells in two groups were increased significantly, while the proportion of Th2 cells were decreased (P<0.01). After treatment, the proportion of Th1 cells in the observation group was significantly higher than that in the control group, while the proportion of Th2 cells was significantly lower than that in the control group (P<0.01). After treatment, the levels of IFN-γ in two groups were significantly increased, but the levels of IL-4 were significantly decreased (P<0.01). After treatment, IFN-γ level in the observation group was significantly higher than that in the control group, while IL-4 level was significantly lower than that in the control group (P<0.01). Conclusion Monteluast sodium combined with interferon α-2b in treatment of children with RSV-induced bronchiolitis can significantly increase the levels of Th1 cells and IFN-γ, and reduce the levels of Th2 cells and IL-4, with significant clinical effect."/>
