摘要: 胰腺疾病具有诊治困难、作用机制复杂等特征。多药联用通过协同作用可实现增强药效、逆转耐药以及减少不良反应,已成为改善胰腺疾病治疗的重要策略。本综述系统归纳了目前常用的药物联用协同作用评价方法,包括等效线图解法、Chou-Talalay法、金正均法及权重配方法,详细阐述了其理论基础、适用范围与局限性,并总结其在胰腺癌与急性胰腺炎等疾病中的应用进展。通过比较不同方法在测量精度及实验依赖性方面的特点,构建了面向胰腺疾病的多药联用效应评价框架,为联合用药方案的筛选与优化提供依据,并为未来协同评价模型的创新与联合治疗策略的开发提供思路。Abstract: Pancreatic diseases are characterized by difficulties in diagnosis and treatment, as well as complex pathogenic mechanisms. Combined drug therapy can enhance therapeutic efficacy, overcome drug resistance, and reduce adverse effects through synergistic interactions and has thus emerged as an important strategy for improving the treatment of pancreatic diseases. This article systematically reviews the commonly used methods for evaluating the synergistic effect of drug combinations, including isobologram analysis, the Chou-Talalay method, Jin’s formula, and the weighted sum method, as well as the theoretical basis, applicability, and limitations of each method, and this article also summarizes the recent advances in their application in pancreatic diseases including pancreatic cancer and acute pancreatitis. By comparing the characteristics of different methods in terms of measurement accuracy and experimental dependence, this article further proposes a framework for evaluating the effect of multi-drug combinations tailored to pancreatic diseases, thereby providing a basis for the screening and optimization of drug combination regimens, as well as new perspectives for the future development of synergistic evaluation models and combined therapeutic strategies.
