Abstract:
Objective To detect the changes of serum integrinβ4 level during both exacerbation and clinical remission of asthmatic patients, and observe the correlation between the changes and balance of Th1/Th2,and to explore the relationship between integrinβ4 and the immune function in asthmatic patients.Methods Thirty?five cases patients who were hospitalized in the Seventh People's Hospital of Shenzhen from May 2013 to June 2015 were collected into this study.Serum interleukin?4(IL?4),interferonγ(IFN?γ),and integrinβ4 were measured with ELISA and western?blotting methods during both exacerbation and remission of asthmatic patients. Then the level of IL?4, IFN?γand integrinβ4 of the two groups were compared. Results The level of serum integrinβ4 protein in the remission stage of asthma was significantly higher than that in the acute attack period, and the difference was statistically significant(0.633±0.032 vs. 0.375±0.107,t=3.31,P<0.01).The level of ser?um IFN?γ in the remission stage of asthma was significantly higher than that in the acute attack period,and the difference was statistically significant((49.3±6.4) g/L vs. (16.7±7.2) g/L,t=3.11,P<0.05),and the level of IL?4 was (25.3±3.6) ng/L and (43.7±11.2) ng/L respectively,the difference between the two groups had sta?tistical significance(t=3.23,P<0.05).The serum level of integrinβ4 and IL?4/IFN?γratio were passively corre?lated(the acute attack period:r=0.749,P=0.05;the remission stage of asthma:r=0.745,P=0.015).Conclu?sion The serum level of integrinβ4 is passively related to IL?4/IFN?γ. Integrinβ4 may play an important role between immune function and the development in airway inflammation of asthmatic patients.
