Objective To evaluate the effects of Pidomorph on serum immune cell level and T cell subsets in children with bronchial asthma.Methods 140 pediatric patients with bronchial asthma from January 2014 to October 2016 in our hospital were randomly divided into experimental group and control group according to the order of admission,70 cases in each groups.The control group was treated with conventional glucocorticoid drugs,and the experimental group was treated with pidotimod.The total effective rate of clinical treatment,the rate of rapid breathing in the flow rate,forced expiratory peak value,forced breathing vital capacity were compared between two groups three weeks after treatment,and the serum levels of immune cells(IgA,IgG,IgM)and T cell subsets(CD3+,CD4+,CD8+)were compared before and after treatment.Results The total effective rate was 92.86％(65/70)in the experimental group and 72.86％(51/70)in the control group,the total effective rate in the experimental group was significantly higher than that in the control group(P<0.05); Forced breathing speed in the speed,forced expiratory peak value,forced breathing vital capacity in the experimental group were better than the control group(P<0.05); After treatment,the levels of serum immune cells(IgA,IgG,IgM)in the experimental group were significantly higher than those in the control group(P<0.05); After treatment,the levels of T cell subsets(CD3+,CD4+,CD8+)in the experimental group were significantly higher than those in the control group(P<0.05).Conclusion Pidotimod is effective and safe in the treatment of bronchial asthma in children,it can effectively regulate T cell subsets and improve the immune function of children with asthma.

Objective: To investigate the effect of macrophage migration inhibitory factor (MIF) on the biology of glioma U87MG and U251 cells. Methods: Silencing MIF gene expression in U87MG cells by RNA interference was monitored by Western blot. MIF low expressing U251 cells were treated at different concentrations of recombinant human MIF (rhMIF) and scratching test and flow cytometry were used to detect cell migration and apoptosis. The protein expression of bcl-2, bax, AKT, p-AKT was detected by Western blot. Results: The ability of migration and anti-apoptosis of U87MG cells silenced by siRNA decreased significantly, and the expression levels of p-AKT and anti-apoptotic protein bcl-2 also decreased; in contrast, the expression level of apoptosis protein bax increased. With increase of rhMIF treatment concentration, the expression levels of MIF protein, p-AKT and bcl-2 in U251 cells were gradually enhanced, whereas the level of apoptosis protein bax was inhibited. Conclusion MIF promotes cell migration and inhibits apoptosis of both U87MG and U251 cells, likely through the regulation of PI3K/AKT signaling pathway.
