[Effect of acupuncture preconditioning combined with PI3K blocker LY294002 on airway inflammation in asthmatic rats]

To observe the effect of acupuncture preconditioning combined with PI3K blocker LY294002 on the expression of PI3K and Akt proteins and genes in the lung tissue and the contents of serum IL-12 and IL-13 in asthmatic rats, so as to explore its preprotective mechanism underlying improving asthma.Sixty male Wistar rats were randomly divided into blank control, model, acupuncture pretreatment + blank, acupuncture pretreatment, acupuncture pretreatment + LY294002 and LY294002 groups (Compared with the blank control group, the content of serum IL-12 was significantly decreased (Acupuncture preconditioning can inhibit airway inflammation in asthmatic rats, which may be associated with its functions in down-regulating the levels of pulmonary PI3K and Akt and serum IL-13 and up-regulating the content of serum IL-12. Acupuncture preconditioning combined with LY294002 has the best effect.
