Bridging Traditional Chinese Medicine with modern scientific validation through network pharmacology
Ulcerative Colitis (UC) is a chronic inflammatory bowel disease affecting millions worldwide, characterized by symptoms like abdominal pain, bloody diarrhea, and persistent inflammation of the colon1 .
While modern medicine offers various treatments, many come with significant side effects. Traditional Chinese Medicine has offered alternative approaches for centuries, with Guchang Zhixie Pill recently validated by modern scientific methods1 .
GCZXP is a traditional Chinese medicine formula with significant clinical advantages in treating intestinal diseases. Originating from "Treatise on Cold Damage and Miscellaneous Diseases" by Zhang Zhongjing of the Eastern Han Dynasty, this prescription consists of six herbs4 .
The monarch drug with antidiarrheal effects
Minister drug that eliminates intestinal damp heat
Minister drug that alleviates pain
Assistant drug that regulates qi and blood flow

Network pharmacology's holistic approach aligns perfectly with TCM principles, which emphasize multi-component, multi-target therapies5 .
Researchers construct biological networks to identify key targets and pathways of TCM components in disease treatment5 .
Unlike conventional drug development focusing on single targets, network pharmacology investigates how multiple compounds interact with multiple targets5 .
This approach helps clarify the pharmacologic basis of TCM drugs and their multi-component, multi-target, multi-pathway treatment approach5 .
| Tool Name | Primary Function | Application in GCZXP Study |
|---|---|---|
| TCMSP | Traditional Chinese Medicine pharmacology database | Screening active compounds and targets3 |
| STRING | Protein-protein interaction network analysis | Constructing PPI networks to identify hub genes6 |
| Cytoscape | Network visualization and analysis | Hub gene acquisition and network visualization1 |
| AutoDock | Molecular docking simulation | Verifying binding between compounds and targets1 |
| Metascape | Gene annotation and analysis resource | GO and KEGG pathway enrichment analysis6 |
The computational predictions were validated through animal experiments using a rat model of colitis induced by dextran sodium sulfate (DSS)1 .
| Molecular Target | Function in Ulcerative Colitis | Effect of GCZXP Treatment |
|---|---|---|
| IL-1β | Pro-inflammatory cytokine | Significantly reduced expression1 |
| CXCL8 | Chemokine attracting immune cells | Significantly reduced expression1 |
| COX-2 (PTGS2) | Enzyme promoting inflammation | Significantly reduced expression1 |
| NF-κB p65 | Central inflammation regulator | Significantly reduced expression1 |
| IκBα | Inhibitor of NF-κB signaling | Increased expression1 |
| Bcl-2 | Anti-apoptotic protein | Increased expression1 |
| Research Tool | Type | Function in TCM Research |
|---|---|---|
| TCMSP | Database | Provides ADME parameters (OB, DL) for TCM compounds; predicts potential targets3 |
| GeneCards | Database | Compiles comprehensive information on human genes; identifies disease-related targets6 |
| GEO Database | Database | Archives functional genomics data; identifies differentially expressed genes in diseases1 |
| Dextran Sodium Sulfate (DSS) | Chemical reagent | Induces experimental colitis in animal models for therapeutic testing1 |
| AutoDock | Software | Performs molecular docking to simulate binding between compounds and protein targets1 |
| STRING | Database | Predicts protein-protein interactions; constructs PPI networks6 |
The discovery that GCZXP increases Bcl-2 expression suggests it may help protect intestinal cells from programmed cell death (apoptosis), contributing to ulcer healing1 .
The successful application of network pharmacology provides a blueprint for modernizing traditional medicines. Future research may lead to optimized formulations and clinical trials5 .
The story of Guchang Zhixie Pill demonstrates that sometimes, looking forward requires us to glance back—and that traditional remedies, when examined with modern tools, may reveal secrets that benefit patients worldwide.
