Methods:80 cases of children with CVA were enrolled in our hospital from June 2015 to June 2016, and were randomly divided into study group and control group. Two groups were both given salbutamol aerosol powder. On this basis, the control group was given Montelukast Sodium Chewable Tablets, while the study group was treated with Huaiqihuang granules. The interleukin 4 (IL-4), interferon-γ(IFN-γ), IgA, IgG and IgE levels and CD4+, CD8+T lymphocyte ratio analyze in children after 3 months of treatment. Results:There were no significant differences between the two groups before treatment (P>0.05). Both IgA and IgG were significantly higher in the two groups after treatment, while IgE was significantly lower (P<0.05). Compared with the control group, the IgA and IgG in the study group were significantly higher than those in the control group (P<0.05), while IgE was significantly lower (P<0.05). After treatment, compared with the control group, the proportion of CD4+ and CD4+/CD8+ in the study group were significantly lower than that of the control group, and the CD8+ratio increased more significantly (P<0.05). After treatment, IL-4 decreased significantly, while IFN-γand IFN-γ/IL-4 were significantly increased (P<0.05), IL-4 level of the study group decreased significantly compared with the control group, and IFN-γincreased significantly compared with the control group, and the level of IFN-γ/IL-4 after treatment was significantly higher than that of the control group (P<0.05). Conclusions: Huaiqihuang granule can improve humoral immunity and cellular immunity of children with CVA, and can adjust the immune cells balance of Th1/Th2, and improve the immune function and prognosis of children with CVA.展开更多

Before treatment and after 6 months of treatment, high-resolution CT was used to determine the airway remodeling index levels, RIA method was used to detect the peripheral blood airway remodeling index contents, and enzyme-linked immunosorbent assay (ELISA) was used to detect the contents of inflammatory mediators in induced sputum and the PARC/CCL-18 in serum.Results: Before treatment, the differences in the airway remodeling degree as well as the contents of inflammatory mediators and PARC/CCL-18 were not statistically significant between the two groups. After 6 months of treatment, CT airway remodeling indexes LA and TA levels of observation group were higher than those of control group while WA level was lower than that of control group, and peripheral blood airway remodeling indexes CTGF, YKL-39, MMP-9 and TIMP-1 contents were lower tha=n those of control group;inflammatory mediators IL-5, IL-6 and IL-8 contents in induced sputum of observation group were lower than those of control group, and serum PARC/CCL-18 content was lower than that of control group.Conclusion:Inhalant combined with Dingchuan Zhike decoction can inhibit the airway remodeling and reduce the airway inflammation in patients with cough variant asthma.展开更多
