摘要:目的:使用蛋白质组学技术对冠心病心血瘀阻证和心肾阴虚证这两种证候之间差异进行研究,以期找到两种证候间差异的物质基础并初步阐释两者差异的信号通路。方法:采集冠心病心血瘀阻证和心肾阴虚证病人的血浆,用荧光差异蛋白电泳(2D-DIGE)、质谱(MALDI-TOF)等蛋白质组学技术分析和鉴定两种证候间蛋白表达的变化,并用生物信息学方法对其涉及的主要信号通路进行分析。结果:蛋白组学研究发现冠心病心血瘀阻证和心肾阴虚证相比共有10种差异表达蛋白,其中7种表达上调,3种表达下调。涉及的通路主要有补体和凝血级联通路及阿尔兹海默症信号通路。结论:补体和凝血级联通路及阿尔兹海默症信号通路与冠心病心血瘀阻证和心肾阴虚证的中医分型有关,但需要进一步验证和机制研究。

Abstract:Objective:To indentify specific protein markers for the syndrome of stagnant blockade of heart blood and yin defi-ciency of heart and kidney of coronary heart disease and interpret the pathway of the difference.Methods:The blood plasma sam-ples of CHD patient with the syndrome of stagnant blockade of heart blood and yin deficiency of heart and kidney were collected to identified the protein expressed differential between the two syndrome by proteomic techniques such as fluorescence differential in-gel electrophoresis(2D-DIGE)and MALDI-TOF,and then analysis major signaling pathway involved with Bioinformatics approach.Results:10proteins are detected differential between the patient with the two syndrome,7of all are up regulated and3 are down regulated.The primary pathways involved includ complement and coagulation cascades pathway and alzheimers disease pathway.Conclusion:It is proved that complement and coagulation cascades pathway and alzheimers disease pathway are related to differentiation for syndrome classification of syndrome of stagnant blockade of heart blood and yin deficiency of heart and kidney.But the conclusion needs further validation and mechanism studies.

冠心病(CHD)是严重危害人类健康的常见病和多发病。据世界卫生组织(WHO)网站公布的消息,2005年世界十大死因中冠心病无论在在高收入、中等收入还是低收入国家中均榜上有名。虽然我国冠心病流行率仍属较低水平,但近年来发病率和死亡率有明显增加的趋势。国家中医药管理局1994年发布的《中医病证诊断疗效标准》[1]将本病分为心血瘀阻、寒凝心脉、痰浊内阻、心气虚弱、心肾阴虚和心肾阳虚6型。
