Effect of Chinese Drugs for Activating Blood Circulation and Detoxifying on Indices of Thrombosis,Inflammatory Reaction,and Tissue Damage in A Rabbit Model of Toxin-Heat and Blood Stasis Syndrome

Objective： To observe the regulatory effect of Chinese drugs for activating blood circulation （ABC） and for activating blood circulation and detoxifying （ABCD） on indices of thrombosis, inflammatory reaction, and tissue damage in a rabbit model of toxin-heat and blood stasis syndrome. Methods： Fifty-four rabbits were randomized into the normal control group, model group, simvastatin group （simvastatin, 0.93 mg/kg per day）, ABC group [Xiongshao Capsule （~ff_）, 0.07 g/kg per day], and ABCD group [Xiongshao Capsule, 0.07 g/kg per day, and Huanglian Capsule （-~L^t）, 0.14 g/kg per day]. All except the normal control group received a single injection of bovine serum albumin and were fed with high-fat diets for 6 weeks. At the end of week 4 of giving high- fat diets, a dose of endoxitin was given by ear vein injection, and a randomized 2-week treatment was initiated. At the end of treatment, blood lipids, circulating endothelial cells, and the pathological changes of the aortic arch were assessed. The serum levels of matrix metalloproteinases （MMP-9）, tissue inhibitors to metalloproteinase （TIMP-1）, granule membrane protein-140 （GMP-140）, plasminogen activator inhibitor-1 （PAl-l）, high-sensitivity C-reactive protein （hs-CRP）, interleukin-6 （IL-6）, and tumor necrosis factor- ~ （TNF- oL ） were determined. Results： Compared with the model group, ABCD group showed decreased serum triglycaride （TG） level, improvement in the pathological change in the aortic arch, and reduction in the number of circulating endothelial cells （4.00_＋ 1.41 per 0.9 p~ L for ABCD group vs 7.83_＋ 1.72 per 0.9 μL for the model group）. In addition, the levels of serum GMP-140, PAl-l, and IL-6 in ABCD group were also significantly reduced [0.79＋0.20 ng/mL, 5.23± 1.39 ng/mL, 40.64 ± 10.11 pg/mL for ABCD group vs 1.08 ± 0.31 ng/mL, 7.28± 2.01 ng/mL, 54.44 ± 13.56 pg/mL for the model group, respectively, P〈0.05]. A trend showing improvement in the indices of thrombosis, inflammatory reaction, and tissue damage was observed in the ABC group when compared to the model group, but the changes were not statistically significant （P〉0.05）. Conclusions： Chinese drugs for activating blood circulation and detoxifying have beneficial effects on regulating indices of thrombosis （GMP-140 and PAl-l） and inflammatory reaction （IL-6） in rabbit model with toxic-heat and blood stasis. The effect of the activating blood circulation and detoxifying drugs in regulating the levels of serum GMP-140, PAl-l, and IL-6 was superior to that of the activating blood circulation drugs.

Effect of Chinese Herbal Medicine for Activating Blood Circulation and Detoxifying on Expression of Inflammatory Reaction and Tissue Damage Related Factors in Experimental Carotid Artery Thrombosis Rats

Objective：To observe the pharmaceutical effect of Chinese drugs for activating blood circulation （Xiongshao Capsule,XSC,芎芍胶囊）and for activating blood circulation and detoxification（Xiongshao Capsule and Huanglian Capsule,XSHLC,黄连胶囊）in terms of the indices of thrombosis,inflammatory reaction and tissue damage related factors in experimental carotid artery thrombosis rats.Methods：Fifty Wistar rats were randomly divided into the sham operation group,the model group,the Simvastatin group（SG）,the activating blood circulation（ABC）group,and the activating blood circulation and detoxifying（ABCD）group,with 10 rats in each group.Simvastatin（1.8 mg/kg）,XSC（0.135 g/kg）and XSHLC（0.135 g/kg）were administered to Simvastatin,ABC and ABCD group by gastrogavage,and an equal volume of normal saline was given to the sham operation group and the model group.After 2 weeks of successive medication,the rats in the model and all drug therapy groups were made into experimental carotid artery thrombosis model.The serum levels of matrix metalloproteinases（MMP-9）,tissue inhibitors to metalloproteinase（TIMP-1）,granule membrane protein-140（GMP-140）,tissue-type plasminogen activator（t-PA）,high-sensitivity C-reactive protein（hs-CRP） and interleukin-6（IL-6）were detected with enzyme-linked immunoassay 24 h later.Results：Compared with the model group,the levels of serum GMP-140,hs-CRP,IL-6 and MMP-9 were significantly decreased,and the level of t-PA was significantly increased in the ABC and ABCD group（P〈0.05）,while the level of serum hs-CRP in ABCD group decreased significantly compared with that in the ABC group（P〈0.05）.Conclusions：Chinese drugs both for activating blood circulation and for activating blood circulation and detoxifying have good effects on regulating indices of thrombosis,inflammatory reaction and tissue damage in experimental carotid artery thrombosis rats.The effect of activating blood circulation and detoxifying drugs on regulating the level of serum hs-CRP is superior to that of activating blood circulation drug alone.
