复方丹参片与丹参片对冠状动脉粥样硬化患者血小板活化抑制作用的比较

目的:比较复方丹参片与丹参片对冠状动脉粥样硬化患者血小板活化的抑制作用。方法:90例冠状动脉粥样硬化确诊患者随机分为复方丹参片组、丹参片组和对照组,疗程2个月;另设正常组30例。分别采用放射免疫法和realtime PCR法检测血浆中环磷酸腺苷(cAMP)、血栓素A(2TXA2)、前列环素(PGI2)及前列腺环素合酶(PTGIS)mRNA的表达情况,并与正常组比较。结果:相对于正常组,冠状动脉粥样硬化患者血浆中cAMP、PGI2、PTGIS mRNA表达明显降低,TXA2表达明显升高。复方丹参片组和丹参片组能明显升高冠状动脉粥样硬化患者血浆中cAMP、PGI2、PTGIS mRNA表达,降低血浆中TXA2的表达,其中复方丹参片组的升高或降低作用显著大于丹参片组。结论:复方丹参片与丹参片均能抑制血小板活化,对冠状动脉粥样硬化患者急性冠脉综合征均有防治作用,但复方丹参片的防治效果强于丹参片。

Comparison of Inhibition Effect of Compound Danshen Tablets on Platelet Activation and That of Danshen Tablets in Patients with Coronary Atherosclerosis

OBJECTIVE：To compare the inhibition effect of Compound danshen tablets on platelet activation and that of Danshen tablets in patients with coronary atherosclerosis.METHODS：90 patients with coronary atherosclerosis were randomized into compound danshen tablet group,danshen tablet group and control group with treatment course of 2 months.30 cases were included into normal group.Radioimmunoassay and realtime RT-PCR were applied to detect mRNA expression of PTGIS,cAMP,TXA2 and PGI2 in plasma respectively and compared with control group.RESULTS：As compared with normal group,the mRNA expression of cAMP,PGI2,PTGIS were decreased markedly while expression of TXA2 was increased remarkably.In compound danshen tablets group and danshen tablets group the mRNA expression of cAMP,PGI2 and PTGIS were increased while the expression of TXA2 was decreased.The increase and decrease of mRNA expression in compound danshen tablets group was higher than that in danshen tablet group.CONCLUSION：Both of Compound danshen tablets and Danshen tablets could inhibit platelet activation and prevent acute coronary syndrome.The effect of Compound danshen tablets on inhibiting platelet activation is better than that of Danshen tablets.
