2、-derivedfactor1,SDF-1)表達(dá)的影響。方法:新西蘭兔25只,免疫損傷結(jié)合高脂飲食法建立動脈粥樣硬化模型,模型動物隨機(jī)分為5組,每組5只。模型組灌胃等量蒸餾水,辛伐他汀組灌胃辛伐他汀水懸液1.7mg/kg,當(dāng)歸補(bǔ)血湯高、中、低劑量組分別灌胃當(dāng)歸補(bǔ)血湯6g/kg、3g/kg、1.5g/kg,每天1次,2周后取兔血檢測VEGF和SDF-1水平,培養(yǎng)并鑒定兔外周血EPCs,MTT法檢測增殖能力,黏附實(shí)驗(yàn)檢測黏附能力,Transwell小室檢測遷移能力,體外血管生成試劑盒檢測形成小管能力。結(jié)果:與模型組比較,辛伐他汀及當(dāng)歸補(bǔ)血湯高、中劑量組家兔血清VEGF和SDF-1水平
3、增高(P<0.05),且EPCs的增殖、黏附、遷移和形成小管能力均有增強(qiáng)(P<0.05)。結(jié)論:當(dāng)歸補(bǔ)血湯可能通過提高循環(huán)VEGF和SDF-1水平來促進(jìn)動脈粥樣硬化EPCs的活性。[關(guān)鍵詞]當(dāng)歸補(bǔ)血湯;內(nèi)皮祖細(xì)胞;動脈粥樣硬化;血管內(nèi)皮生長因子;基質(zhì)細(xì)胞源性因子1[中圖分類號]R363[文獻(xiàn)標(biāo)志碼]Adoi:10.3969/j.issn.1000-4718.2012.02.004EffectsofDangguiBuxuedecoctiononendothelialprogenitorcells,serumVEGFandSDF-1inatheroscleroticrabbitsQI
