Each disease has its own development regulation and presents different characters at different time. Intervention based on dynamic syndrome is the distinguishing feature of the treatment based on syndrome differentiation,and it presents the relationship of the degree of correlation between formula and syndrome and effect when applied to clinical treatment. However, there has not ever reported the relationship of TCM syndrome and formula from the perspective of syndrome development based on time and intervention based on dynamic syndrome. This article is based on experiential background of syndrome development and TCM formula intervention in type 2DM and TCM dynamic evolutionary syndrome of type 2 diabetes insulin resistance rat model. There we follows the natural course of disease,emphasis on the correlation between formula and syndrome,use systems biology methods to discuss the different syndrome characteristics in different stages at integrated systems and proteomics levels,and to compare the effect similarities and differences for relevant formula at different stages,and to explore biological basis for animal model. This paper has great effect on regulation of TCM treatment,discussion the correlation between syndrome and formula,and reveal of scientific connotation so on.
每个疾病都有其一定的发展演变规律,表现出时相性演变特征(证)。据证动态干预是中医辨证论治的特色内容,落实于临床辨证、立法、组方用药的具体过程中,表现为方证关联程度与疗效之间的密切关系。目前基于病证结合,特别是从证的时间演变和方药动态干预的纬度上进行中医方证关系的探讨尚未有见。本课题基于2 型糖尿病中医证候演变及其方药干预的经验背景,在前期2 型糖尿病胰岛素抵抗大鼠模型中医证候演变观察的基础上,以疾病的自然病程为主线,侧重从中医方证动态关系的角度,运用系统生物学方法,在整体多系统及蛋白组学层面深入探讨该模型不同阶段的证候特征,比较观察相关方药分阶段因证干预的效应异同,探察该模型的中医证候演变规律和方药干预中的方-证关联性及其生物学基础。该课题对于建立体现中医辨证论治特色的实验治疗学研究平台,探索中医证治规律,论证病证和方药间的对应关系及揭示其现代科学内涵均具有重要的意义。
“方证相关”不仅是中医辨证论治中的重要内容,也是临床选方用药的经验基础。.本项目基于中医方证相关的原理,从疾病发展和证候演变的角度,对高脂饲料喂养(HF)和高脂饲料喂养+小剂量STZ(HF/STZ)两种不同方法诱导的T2DM大鼠模型进行系统评价,运用蛋白组学技术获得两种T2DM大鼠模型血清差异蛋白表达谱;对HF/STZ模型大鼠因时演变的西病中证的特征进行了较为深入的研究,通过跨系统多维数据的系统分析,获得该模型大鼠的基本病理特征和其因时变化的病生理学内涵、中医证候(气阴两虚、痰浊、瘀血)演变规律及其与证候关联的实验室指标群;在此基础上,采用异方同证的排他性方法,系统观察体现三种不同治法(益气养阴、益气养阴化痰、益气养阴化痰祛瘀)的方药分别作用于模型不同阶段(气阴二虚、气阴二虚痰浊、气阴二虚痰瘀三证)的效应异同,进一步获得三方与三证关联的生物学基础。研究还比较中药益气养阴化痰祛瘀方与西药匹格列酮作用于T2DM气阴二虚兼痰瘀模型大鼠的血清差异蛋白谱及其各自蛋白组学特点,发现方药作用的潜在分子靶标;比较观察了中药、西药、中西药合用对模型不同阶段的干预效应,发现单用中药(因证用方)对模型各阶段的综合疗效均优于单用西药和中西药合用。. 该课题对于建立体现中医辨证论治特色的实验治疗学研究平台,探索中医证治规律,论证病证和方药间的对应关系及其生物学基础,评价中西药联合用药的合理性均具有重要的科学意义。
