【摘要】:目的研究灸法熱刺激對人臍靜脈血管內(nèi)皮細(xì)胞中(HUVECs)Caspase-3基因和蛋白表達(dá)的影響,探討灸法中溫?zé)岽碳さ目沟蛲黾按俚蛲龅男?yīng)機(jī)制。方法原代HUVECs分為正常組(37℃)、適宜溫?zé)岽碳そM(40℃)和凋亡組(43℃),正常組不做任何處理,適宜溫?zé)岽碳そM置于40℃培養(yǎng)箱刺激30min,凋亡組置于43℃培養(yǎng)箱中刺激30min,每天2次,各組于第1天、2天、3天刺激結(jié)束4h后用MTT比色法檢測HUVECs生長活力,第3天用QPCR和Western blot技術(shù)檢測Caspase-3基因和蛋白表達(dá)。結(jié)果三組HUVECS生長活力逐漸增強(qiáng),與第1天和第2天比差異均有統(tǒng)計學(xué)意義(P0.001);每天適宜溫?zé)岽碳そM細(xì)胞生長活力較正常組增強(qiáng),差異均有統(tǒng)計學(xué)意義(P0.001或P0.05);每天凋亡組細(xì)胞生長活力較正常組減弱,差異均有統(tǒng)計學(xué)意義(P0.01或P0.001)。第3天,與正常組比,適宜溫?zé)岽碳そMHUVECS內(nèi)Caspase-3的基因和蛋白表達(dá)均降低(P0.001),凋亡組HUVECS內(nèi)Caspase-3的基因和蛋白表達(dá)均升高(P0.05),凋亡組與適宜溫?zé)岽碳そM比,HUVECS內(nèi)Caspase-3的基因和蛋白表達(dá)均升高(P0.001)。結(jié)論灸法熱刺激可調(diào)控HUVECs內(nèi)的Caspase-3表達(dá)來調(diào)控細(xì)胞凋亡的過程,為全面認(rèn)識灸法"活血化瘀"的生物學(xué)機(jī)制提供新的實驗依據(jù)。
