[Influence of separate components of Yiqi Qingwen Jiedu mixture to serum inflammatory cytokines of mice infected with influenza virus FM1].

OBJECTIVE

To observe dynamically the influence of 4 parts of forming of YQJM (Yiqi Qingwen Jiedu mixture) (referred to as 4 parts of forming) including the methods of relieving superficies with acrid-warm, relieving superficies with acrid-cold, clearing away heat and poison and replenishing Qi to serum inflammatory cytokines of the model mice infected with influenza virus. And to discuss the mechanism of 4 parts of forming of anti-influenza immune injury and restoration.

METHOD

Made the model with the mice infected by FM1 influenza infection, used ELISA method, observed dynamically the influence of four methods on the level of serum TNF-alpha, IL-6, IL-1, IFN-gamma and IL-10 inflammatory cytokines.

RESULT

The level of serum TNF-alpha, IL-6, IL-1 and IFN-gamma of mice infected by FM1 significantly increased, while the level of serum IL-10 was lower than the control group on the first day of infection, but the levels were much higher than the control group in 3 to 7 days after infection. The method of relieving superficies with acrid-warm significantly decreased the levels of serum TNF-alpha, IL-6, IL-1 on the 5th day after infection, and significantly increased the levels of serum IL-10 on the 3rd and 7th day after infection. The method could inhibit the immune injury to some extent. The method of relieving superficies with acrid-cold decreased the levels of serum TNF-alpha and IL-6 in 5 to 7 days after infection, increased the level of serum IL-1 on the 3rd day after infection, decreased the level of serum IL-1 on the 7th day after infection, significantly increased the levels of serum IL-10 in 1 to 3 days and on the 7th day after infection. The method could be against inflammatory injury. The method of clearing away heat and poison decreased the levels of serum TNF-alpha, IL-6, IL-1 after infection in 3 to 5 days and on the 7th day, and significantly increased IL-10 each time after infection. It exhibited more strong inhibition of inflammatory injury and repair. The method of replenishing Qi significantly decreased the level of serum TNF-alpha and IL-6 in 3 to 7 days after infection, increased the level of serum IL-1 the first 3 days after infection, but decreased the level of serum IL-1 on the 7th day after infection. The method significantly increased the levels of serum IL-10 in 3 to 5 days and on the 7th day. It exhibited inhibition of inflammatory injury. The method of relieving superficies with acrid-cold significantly increased the levels of serum IFN-gamma in 3 days after infection, while the methods of clearing away heat and poison and replenishing Qi significantly increased the levels of serum IFN-gamma in 1 to 3 days and on the 7th day. They exhibited anti-virus and suppression of the immune injury.

CONCLUSION

Chinese medicine could correct the imbalance of inflammatory cytokines and be against injury, promote injury restoration, and protect the body.
