From Ancient Texts to Labs: How Zhishi Xiebai Guizhi Decoction Uses Modern Molecular Mechanisms to Tackle Atherosclerosis?

 

When traditional Chinese medicine (TCM) compound formulas meet modern molecular biology, they often spark surprising research outcomes. A recent study on the classic TCM formula Zhishi Xiebai Guizhi Decoction (ZSXBGZD) has, for the first time, clearly clarified its core molecular mechanism in treating atherosclerosis (AS). This provides solid scientific evidence for the "modern application of ancient formulas" and reveals the potential value of TCM compound formulas in treating cardiovascular diseases.

 

Atherosclerosis, the "culprit" behind cardiovascular and cerebrovascular diseases, primarily stems from the formation and progression of atherosclerotic plaques on blood vessel walls. These plaques gradually block blood vessels, disrupt blood flow, and eventually trigger severe conditions like coronary heart disease and cerebral infarction. In the past, treatments for atherosclerosis mostly focused on regulating blood lipids and inhibiting platelet aggregation. However, this study explores a new pathway for ZSXBGZD to intervene in the disease—from the perspective of "cellular signaling pathways" and "cellular fate regulation."

 

Through a series of experiments, the research team found that ZSXBGZD does not act through a single target. Instead, it targets the AGE-RAGE pathway, a key signaling pathway in the development of atherosclerosis. When this pathway is activated, it exacerbates vascular endothelial damage, promotes inflammatory responses, and accelerates plaque formation. ZSXBGZD can precisely regulate the activity of this pathway, acting like a "brake" for vascular health. More importantly, this regulation triggers subsequent "chain benefits": on one hand, it activates cellular autophagy, helping clear abnormal proteins and damaged cells accumulated in blood vessel walls, thereby reducing the "raw materials" for plaque formation; on the other hand, it inhibits cellular apoptosis, protecting the normal function of vascular endothelial cells and maintaining the integrity of blood vessel walls. With this combination of "clearing" and "protecting," the size of atherosclerotic plaques is naturally reduced, and disease progression is effectively curbed.

 

Notably, the study further identified two natural components in the formula that play a core role: Limonin and Obacunone. These two components were confirmed as the key "active factors" that regulate the AGE-RAGE pathway and influence cellular autophagy and apoptosis—equivalent to finding the specific "molecular keys" to the "efficacy code" of ZSXBGZD. This discovery not only answers the traditional question of "why TCM compound formulas work" but also points out a clear direction for the subsequent development of more precise TCM extracts and even innovative drugs. In the future, it may be possible to develop more targeted and effective atherosclerosis treatment plans by purifying these two components.

 

From a classic formula recorded in Synopsis of the Golden Chamber (used for "chest impediment," a condition similar to modern coronary heart disease) to a remedy scientifically proven to treat atherosclerosis by regulating molecular pathways, the research breakthrough of ZSXBGZD represents an important approach to TCM modernization: it does not replace modern science with traditional experience, but uses scientific methods to interpret traditional wisdom, allowing ancient formulas in historical texts to regain new vitality that aligns with contemporary medical understanding. For patients, this means more TCM treatment options that balance "safety" and "scientific validity" may be available in the future; for the field of TCM research, it provides a reference model for exploring the mechanisms of compound drugs.

 

As more similar studies advance, we have reason to believe that more TCM compound formulas will move beyond the scope of "empirical medicine" and find a "way to communicate" with modern diseases at the molecular and cellular levels. This is precisely a crucial step for TCM to integrate into the modern medical system and go global.
