Abstract:
OBJECTIVE To investigate the influence of Huayu xiaozhong decoction （HXD） on inflammatory response in rats with deep vein thrombosis （DVT）. METHODS The male SD rats were divided into control group （CK group）， model group （Model group）， HXD low-dose group （HXD-L group， HXD 10.86 mg/kg）， HXD medium-dose group （HXD-M group， HXD 21.71 mg/kg）， HXD high-dose group （HXD-H group， HXD 32.57 mg/kg）， positive control group （LMWHS group， low molecular weight heparin sodium 600 IU/kg）， silent information regulator 2 （SIRT2） inhibitor group （AK-7 group， AK-7 20 mg/kg）， HXD-M+AK-7 group （HXD 21.71 mg/kg+AK-7 20 mg/kg）， with 12 rats in each group. Except for the CK group， the DVT rat was induced by the Reyers method in other groups； after modeling， administration groups were given relevant medicine intragastrically/intraperitoneally， once a day， for consecutive 2 weeks. Twenty-four hours after the last medication， the coagulation function indexes [activated partial thromboplastin time （APTT）， thrombin time （TT）， prothrombin time （PT）， fibrinogen （FIB）] and inflammatory indexes in serum and inferior vena cava tissue [interleukin-1β （IL-1β）， IL-6， tumor necrosis factor-α （TNF-α）] of rats were detected. The formation of thrombus was observed， and the wet and dry masses of the thrombus were weighed. The protein expressions of tissue factor （TF） and SIRT2 as well as the phosphorylation and acetylation levels of nuclear factor kappa B （NF-κB） p65 in inferior vena cava tissue were detected. RESULTS Compared with CK group， APTT， TT and PT of rats in Model group were shortened significantly（P＜0.05）； the content of FIB， the levels of IL-1β， IL-6 and TNF-α， wet weight and dry weight of venous thrombus， TF protein staining score， the phosphorylation and acetylation levels of NF-κB p65 protein increased significantly （P＜0.05）； the inferior vena cava was full of thrombus， and the protein expression of SIRT2 decreased （P＜0.05）. Compared with Model group， above indexes of HXD-L group， HXD-M group， HXD-H group and LMWHS group were improved， while the improvement effects of HXD-M group， HXD-H group and LMWHS group were significantly better than those of HXD-L group （P＜0.05）. The trends of the corresponding indicators in AK-7 group were opposite to the above （P＜0.05）； AK-7 attenuated the inhibitory effect of medium-dose HXD on the inflammatory response in model rats （P＜0.05）.CONCLUSIONS HXD may inhibit the inflammatory response of DVT rats by activating SIRT2/NF-κB signaling pathway.
