To study the anticoagulant effect of Xiang-Qi-Tang (XQT),the mice model of endotoxemia was established to detect the expression of coagulation factors and their regulatory proteins in serum and aorta.The results showed that XQT could decrease the expression of TF and increase the expression of tPA in the aorta of mice with endotoxemia,and also decrease the expression of sEPCR in the serum.We further found that XQT caused the decrease of sEPCR through the regulation of PKC δ and ADAM17 to contribute the anticoagulation in mice.This study may provide a new strategy for treating endotoxin-induced disease and provide evidences for further researching the pharmacological action of XQT.

Objective To establish a rabbit model of restenosis and analyze the expressions of VEGFmRNA and TGF-?_1mRNA during the intimal proliferation.We also explored the relationship between VEGFmRNA,TGF-?_1mRNA and restenosis.Methods 40 healthy male New Zealand white rabbits were evenly divided into three injury groups and one control group.Right carotid arteries were injured with PCI balloon in the injury groups.10 rabbits of each injury group were sacrificed on weeks 1,2 and 4 after the injury.VEGFmRNA and TGF-?_1mRNA were examined by in situ hybridization.All the samples were analyzed using a computerized imaging analysis system.Results In the injury groups,neointimal areas were significantly larger than those in control group(P
