Prevention and Treatment Effect of Yiqi Huoxue Fang on Deep Venous Thrombosis / 医药导报

ABSTRACT

Objective To explore the intervention mechanism of Yiqi Huoxue Fang on deep venous thrombosis ( DVT) of rabbit model,by observing its effects on serum t-PA and PAI-1,D-D,NO,CRP,PT,blood rheology and vascular pathology. Methods Fifty New Zealand rabbits were randomly selected.Ten rabbits were served as blank control group.DVT animal models were established in the remaining 40 rabbits, which were randomly divided into model control group, Yiqi Fang group, Huoxue Fang group and Yiqi Huoxue Fang group (n=10 each group).The changes of serum t-PA,PAI-1,D-D,NO,CRP,PT and pathological changes of blood vessel were observed after 7-days treatment. Results As compared with the blank control group, the serum t-PA,PAI-1,D-D,CRP and PT were significantly increased in the model control group,Yiqi Fang group,Huoxue Fang group and Yiqi Huoxue Fang group (all P0.05 in Yiqi Huoxue Fang group vs.the blank control group).As compared with model control group,the serum t-PA,NO,D-D increased,PAI-1 and CRP value reduced in Yiqi Huoxue Fang group and Huoxue fang group (P<0.01 or P<0.05).As compared with Yiqi Huoxue Fang group,serum t-PA in both Yiqi Fang group and Huoxue Fang group was significantly lower (P<0.01 and P<0.05) ,other indexes were significantly higher than that in Yiqi Huoxue Fang group (serum PAI-1,P<0.01 in Yiqi Fang group;NO and D-D,P<0.01 or P<0.05 in Yiqi Fang group;CRP value,P<0.01).Vascular pathology showed that blood vessels,especially vascular endothelia,of Yiqi Huoxue Fang group were most slightly injured,with slightest infiltration of inflammatory cells. Conclusion Yiqi Huoxue Fang can prevent DVT through regulating t-PA and PAI-1,keeping the fibrinolytic system function at a relatively high level,protecting vascular intima and relieving the inflammation in venous thrombosis.
