Atherosclerosis (AS), a chronic inflammatory disease affecting systemic vasculature, constitutes the primary pathological basis for cardiovascular and cerebrovascular events1. Its pathogenesis involves complex interactions among genetic, environmental, psychosocial, and multifactorial pathological factors, exhibiting multistage and polygenic characteristics. Although current therapeutic strategies-particularly lipid-lowering agents such as statins and Proprotein Convertase Subtilisin/Kexin Type 9(PCSK9) inhibitors-effectively reduce low-density lipoprotein cholesterol (LDL-C) levels, they do not fully address the residual inflammatory risk that drives recurrent cardiovascular events2. Furthermore, therapy-associated adverse effects (e.g., new-onset diabetes, myotoxicity, hepatorenal impairment) limit the long-term use and intensification of lipid-lowering therapy3,4. These limitations highlight the need for complementary approaches that directly target vascular inflammation, including anti-inflammatory therapies, to further reduce cardiovascular risk beyond lipid-lowering alone.
In traditional Chinese medicine (TCM), AS falls under the categories of "chest impediment" (Xiong Bi) and "vessel accumulation" (Mai Ji), with "phlegm-stasis entanglement" (Tanyu Hujie) recognized as its core pathogenesis. Guided by the "stasis-transforming hydrotherapy" (Yuneng Huashui) principle, our research group developed the "San Jie Tong Mai Formula (SJTMF)" composed of 14 herbs, including Salvia miltiorrhiza (Danshen) and Whitmania pigra Whitman (Shuizhi), to synergistically resolve phlegm-turbidity, dissipate stasis, and promote diuresis. Preliminary clinical studies demonstrated SJTMF's efficacy in significantly improving lipid profiles and stabilizing/reversing atherosclerotic plaques in elderly patients with carotid AS5. Experimental investigations further revealed its capacity to inhibit AS progression by modulating macrophage polarization and autophagy pathways6,7. Nevertheless, the multi-component, multi-target, and multi-pathway characteristics of TCM formulas present challenges in systematically elucidating their integrated regulatory mechanisms using conventional reductionist approaches.
To explore the molecular mechanisms mediating SJTMF's anti-atherosclerotic effects and address the challenges, this study employed an integrated multidisciplinary strategy. Network pharmacology, conceptualized by Hopkins8,9, was utilized to construct a multidimensional "herbal component-target-disease pathway" network. This approach facilitated the prediction of SJTMF's primary active compounds and potential therapeutic targets for AS intervention, consistent with TCM's holistic regulatory features. Complementing this, proteomics technology, leveraging high-throughput and high-precision qualitative and quantitative protein analysis10, dynamically monitored changes in the AS-associated protein expression profile after SJTMF intervention in animal models. This enabled the identification of key effector molecules and signaling events, thereby furnishing experimental evidence for mechanistic exploration. Subsequently, high-precision molecular docking simulations were performed to evaluate the binding modes and binding energies between the core targets predicted by network pharmacology and the key bioactive components, providing a theoretical basis for potential component-target interactions11. Compared to alternative approaches, such as relying solely on network pharmacology predictions (prone to high false-positive rates and lacking experimental validation)12 or combining only proteomics with molecular docking (which may fail to capture system-level interactions predicted by network analysis), this integrated strategy synergistically addresses these inherent limitations13.
By integrating multidimensional techniques, this study aims to systematically elucidate the key pharmacodynamic material basis, core target network, and multi-pathway synergistic mechanisms of SJTMF. Thus, providing mechanism-driven theoretical support for advancing the modernization of TCM and the development of innovative drugs.
