小核酸药物主要包括小干扰核糖核酸(small interfering RNA,siRNA)、反义寡核苷酸(antisense oligonucleotide,ASO)、微小RNA(microRNA,miRNA)、信使RNA(messenger RNA,mRNA)以及核酸适配体(aptamer)等,可通过与靶分子的RNA结合,抑制其翻译或调控,具有高度特异性、持久性和可治愈性,近年来颇受关注。新近发现中药动植物来源的miRNA自身稳定并可稳定存在于动物或人体的血液与组织器官,而且可通过参与调控多种靶蛋白的表达发挥药理作用。该文概述了源自中药及天然药物的小核酸药物发现及其跨界调控机制,探讨这类新兴药品带来的技术挑战与监管问题,可为中药复杂性作用机制阐释、中药及天然药物来源的小核酸新药研制及监管科学研究提供新的思路和方法。

中医证候客观化与中药复方药效学评价标准一直是中医中药基础研究难以突破的关键环节。现代免疫学认为，机体是一个平衡体，免疫失衡是百病之源。中医诊治疾病的思维方式也是“平衡”，认为生病是因为人体“偏性”，即“阴阳、表里、寒热、虚实”等失衡所致。整合医学催生了广义免疫组学，免疫功能（免疫平衡）系统评价已是整合医学诊疗模式的重要依据，而平衡也是中医整体观核心思想。由此，可以预见，广义免疫组学整体或局部组织平衡原理为中医整体观与现代整合医学桥接理论基础之一，是中医症候客观化研究与中药复方药效评价的重要依据之一。由此，笔者根据动态、整体精准医学模式背景，根据新病因观，提出运用信息学、统计学方法构建基于广义免疫组学整体与局部组织平衡原理的中医证候客观化与中药复方评价体系。该体系将会深入揭示中医整体观理论科学内涵，为中药复方药效评价提供新思路新方法，亦可作为亚健康人群免疫力筛查，为中医分子治未病学科发展提供理论支持等。随着临床样本量与数据量不断积累，该评价体系将更精准、更智能。
