The protective effect of Qingfei Huatan decoction on pulmonary function and its influence on the immunological function in children with severe pneumonia

The mixed Chinese herbs Qingfei Huatan decoction and the routine treatment combination has a good clinical effectiveness in children with severe pneumonia. It can effectively promote the pulmonary function of children. Its effect may be correlated with the suppression of inflammation in the body and the improvement of the immunological function in children.

120 children with severe pneumonia hospitalized from May 2018 to May 2020 were enrolled in the study and randomly placed into an observation group or a control group (n=60 in each group). The control group was administered conventional treatment, and the observation group was administered the mixed Chinese herbs Qingfei Huatan decoction in addition to the treatment administered to the control group. The therapeutic efficacy, the changes in pulmonary function, the serum inflammatory levels, and the peripheral blood T lymphocyte subsets were compared between the two groups.

This research explores and analyzes the protective effect of the mixed Chinese herbs Qingfei Huatan decoction on the pulmonary and immunological functions in children with severe pneumonia.

The total effective treatment rate in the observation group was critically superior to the total effective treatment rate in the control group (P<0.05). The FVC, FEV1, and FEV1/FVC levels in the two groups after the treatment were remarkably higher than they were before the treatment (P<0.05), and the observation group had superior post-treatment pulmonary function than the control group (P<0.05). The TNF-α, IL-6, and CRP levels in the two groups in after the treatment were lower than they were before the treatment (P<0.05), and the observation group had lower post-treatment inflammatory cytokine levels than the control group (P<0.05). The two groups' CD4+ and CD4+/CD8+ levels increased substantially after the treatment compared to before the treatment (P<0.05), and the posttreatment levels in the observation group were notably higher than they were in the control group (P<0.05).
