Analysis of the Mechanism of Action of Traditional Chinese Medicine in the Treatment of Postoperative Lumbar Pain Based on Data Mining, Network Pharmacology, and Molecular Docking Techniques
Abstract: Objective: To analyze the medication patterns of traditional Chinese medicine (TCM) in the treatment of postoperative lumbar pain and to predict its potential mechanisms of action by integrating data mining, network pharmacology, and molecular docking techniques. Methods: Chinese and English databases were systematically retrieved to identify clinical studies on Chinese medicine compounds for treating postoperative lumbar pain. Syndrome elements, high-frequency Chinese herbal medicines, and prescription compatibility patterns were extracted,and core herbal combinations were integrated. Disease-related targets were retrieved from The Human Gene Database (GeneCards),Online Mendelian Inheritance in Man (OMIM),Therapeutic Target Database (TTD),and Pharmacogenetics and Pharmacogenomics Knowledge Base (PharmGKB), and the intersection of herbal targets and disease targets was obtained using an online Venn diagram platform. A "herbal-component-target-disease" network and a protein-protein interaction (PPI) network were constructed. Gene Ontology (GO) functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed on the intersecting targets, followed by molecular docking validation. Results: The core disease location of postoperative lumbar pain involved the meridians,liver,sinews and bones,and kidney,with the pathological characteristics being qi stagnation and blood stasis. The core therapeutic principles were activating blood and resolving stasis,tonifying qi and nourishing blood,and tonifying the liver and kidney to strengthen sinews and bones. The high-frequency herbs included Angelicae Sinensis Radix, Glycyrrhizae Radix et Rhizoma, Astragali Radix, Achyranthis Bidentatae Radix, and Chuanxiong Rhizoma. The high-frequency herbs were mainly blood-activating and stasis-resolving medicinals, qi-supplementing medicinals, and blood-tonifying medicinals; they were predominantly warm in nature, sweet in flavor, and mainly entered the liver meridian. The core herbal combination was composed of Spatholobi Caulis, Croci Stigma, Glycyrrhizae Radix et Rhizoma,Angelicae Sinensis Radix,Chuanxiong Rhizoma ,Persicae Semen,Astragali Radix, Pheretima, Achyranthis Bidentatae Radix, Cinnamomi Ramulus, and Olibanum. Network pharmacology screening identified the key active ingredients of the core herbal combination as baicalein,stigmasterol,β-sitosterol,quercetin, etc., and the core targets as tumor protein p53 (TP53), tyrosine-protein kinase Src (SRC), signal transducer and activator of transcription 3 (STAT3) , phosphatidylinositol 4, 5-bisphosphate 3-kinase catalytic subunit alpha (PIK3CA), and phosphatidylinositol 3-kinase regulatory subunit 1 (PIK3R1), among others. KEGG analysis mainly involved the advanced glycation end products-receptor for advanced glycation end products (AGE-RAGE) signaling pathway in diabetic complications,the mitogen-activated protein kinase (MAPK) signaling pathway,and the phosphatidylinositol 3-kinase/protein kinase B (PI3K-Akt) signaling pathway. Molecular docking results showed that the binding energies of all key active ingredients binding to core targets were < -5.0 kcal/mol. Conclusion: The treatment of postoperative lumbar pain with TCM follows a principle of "activating blood and resolving stasis,tonifying deficiency and unblocking collaterals. " The core herbal combination may exert analgesic effects by modulating inflammation and neuropathic pain-related pathways through multi-component and multi-target interactions.
