Objectives: To investigate the therapeutic effect and mechanism of Danggui Buxue Tang in the treatment of biceps longus tendon lesions, and to preliminarily explore the relevant factors affecting this injury. Methods: Using network pharmacology analysis methods, the potential mechanism of Danggui Buxue Tang in treating key lesions of the long head of the biceps brachii muscle was studied. Results: Model analysis revealed 44 protein-protein interactions associated with long head binding. The distribution of 19 strongly correlated targets is Pharmapper>SEA>Stitch>Swiss. Further discovery revealed 17 immune system and inflammation related KEGG pathways with P values less than 0.01. The TNF and sphingolipid signaling pathways are associated with inflammation, while the MAPK signaling pathway is associated with immunity. Finally, it was found that the FoxO and HIF-1 signaling pathways are directly associated with long head restraint injury in the biceps brachii muscle. Conclusion: Danggui Buxue Tang inhibits related pathways, regulates the immune system, reduces inflammation, and alleviates disease progression. Danggui Buxue Tang can be an effective choice for treating combined lesions of the long head of the biceps brachii muscle.
