Résumé
Acute pancreatitis （AP） is one of the most clinically common acute digestive disorders characterized by quick onset，rapid progression，severe condition，and high mortality. If the disease is not timely intervened in the early stage，it can develop into severe AP in the later stage，which damages the long-term quality of life and brings serious economic burden to patients and their families. However， the pathogenesis of this disease is complex and has not been fully explained. The generation and development of AP is closely related to many signaling pathways. Among them，Toll-like receptor 4（TLR4），as a transmembrane signal transduction receptor，can mediate immune response and inflammatory response，and play a key role in the occurrence and development of AP. Traditional Chinese medicine（TCM）can regulate the TLR4 signaling pathway with multiple targets，multiple effects，and multiple administration methods to inhibit inflammatory response，and effectively intervene in the progression of AP， which has gradually become a new craze for preventing and treating AP. Many studies have shown that TCM has obvious advantages in the prevention and treatment of AP. It can effectively treat AP by regulating TLR4 signaling pathway，strengthening immune resistance and defense，and inhibiting inflammatory response. Despite of the research progress，there is still a lack of comprehensive review on TCM regulation of TLR4 signaling pathway in the treatment of AP. Therefore，the literature on TCM regulation of TLR4 signaling pathway published in recent years was systematically reviewed and elaborated，aiming to provide new ideas for the treatment of AP and further drug development.
Résumé
Ulcerative colitis （UC） is a disease that affects the mucosal and submucosal layers of the colon and is characterized by inflammation of the intestinal mucosa. The incidence of UC is increasing year by year， and it is complex and refractory， severely impacting the physical and mental health of patients. The pathological mechanism of this disease is complex， with immune responses and uncontrollable inflammatory reactions in the intestine being important physiopathologic mechanisms. Toll-like receptor 4 （TLR4）， as a transmembrane signaling receptor， plays a key role in mediating immune responses and inflammatory reactions in the development of UC. Currently， the treatment of UC mainly relies on salicylic acids， glucocorticoids， and other agents to reduce intestinal inflammation. While these drugs can partially inhibit the progression of the disease， they often come with significant adverse effects and the potential for relapse upon discontinuation. Traditional Chinese medicine （TCM） offers multiple pathways， effects， and targets for regulating the TLR4 pathway， suppressing inflammatory responses， and effectively intervening in the progression of UC. This approach has become a hot topic in the prevention and treatment of UC. Numerous studies have shown that TCM treatment of UC has unique advantages. TCM can enhance immune defenses， suppress inflammatory responses， promote intestinal mucosal healing， and maintain the balance of the intestinal microbiota by regulating the TLR4 signaling pathway， thereby effectively treating UC， with substantial progress achieved. However， there is currently a lack of comprehensive reviews on the role of TCM in regulating the TLR4 signaling pathway for the treatment of UC. Therefore， this article systematically summarized the relationship between the TLR4 signaling pathway and UC， as well as the role of TCM in this context， by reviewing relevant literature from recent years， aiming to provide new insights into the potential treatment and new drug development for UC.
