Chinese Medicine in the Treatment of Ulcerative Colitis: The Mechanisms of Signaling Pathway Regulations.

Ulcerative colitis (UC) is a common clinical inflammatory bowel disease characterized by repeated attacks, difficult treatment, and great harm to the physical and mental health of the patients. The occurrence and development of UC were closely related to the physiological and pathological processes, such as intestinal inflammatory reaction, oxidizing reaction, and immune response. Treatment of ulcerative colitis using Western medicine is often associated with a number of limitations and adverse events. There is a long history of using traditional Chinese medicine in dealing with this medical condition. Commonly used traditional Chinese medicines for the treatment of UC include Caulis Sargentodoxae, Flos Lonicerae, Fructus Cnidii, etc. Additionally, classic prescriptions such as Gegen Qinlian Formulae and Zuojin Pills can also be used to treat UC. To enrich the traditional Chinese medicine theory, the cognitive theory and perspective of network pharmacology and bioinformatics research of cell signal transduction mechanism of UC are emerging rapidly. Modern pharmacological studies focus on underlying mechanisms for the management of UC with Chinese medicine monomers, single Chinese medicines, and traditional Chinese medicine formulations, alleviating the symptoms of UC, controlling the development of intestinal inflammation, and restoring intestinal function through the regulation of key molecular signaling pathways, including PI3K/Akt, NF-[Formula: see text]B, JAK/STAT, MAPK and Notch. By summarizing current research progressions, this review provides key references for the in-depth exploration of the mechanisms focused on signaling pathways for the clinical management of UC using traditional Chinese medicine.
