RESUMO

Reflux esophagitis is an inflammatory disease of esophageal mucosa damage caused by the reflux of gastric contents into the esophagus. Its incidence is on the rise, and it has become an important precancerous disease of esophageal cancer. Studies have shown that the continuous inflammatory response stimulates the esophageal mucosa, causing abnormal proliferation of esophageal epithelial cells and damage to esophageal mucosal tissue, which eventually leads to the occurrence of heterogeneous hyperplasia and even carcinogenesis. The nuclear transcription factor-kappa B (NF-κB) signaling pathway is one of the most classical inflammatory and cancer signaling pathways. It has been found that abnormal activation of the NF-κB signaling pathway is crucial to the development and prognosis of reflux esophagitis and esophageal cancer. It is widely involved in the proliferation, autophagy, apoptosis, and inflammatory response of esophageal epithelial cells and tumor cells, accelerating the transformation of reflux esophagitis to esophageal cancer and making it a potential target for the treatment of reflux esophagitis and esophageal cancer. Currently, there is no specific treatment for reflux esophagitis and esophageal cancer, and large side effects often appear. Therefore, finding a promising and safe drug remains a top priority. In recent years, traditional Chinese medicine scholars have conducted a lot of research on NF-κB signaling pathway, and the results indicate that NF-κB signaling pathway is an important potential target for traditional Chinese medicine to prevent and treat reflux esophagitis and esophageal cancer, but there is a lack of comprehensive and systematic elaboration. Therefore, this paper summarized the relevant studies in recent years, analyzed the relationship among NF-κB signaling pathway, reflux esophagitis, esophageal cancer, and transformation from inflammation to cancer, and reviewed the research literature on the regulation of the NF-κB signaling pathway in traditional Chinese medicine to prevent and treat reflux esophagitis and esophageal cancer, so as to provide new ideas for the prevention and treatment of reflux esophagitis and esophageal cancer.

RESUMO

Cardiovascular diseases are the leading cause of death in the world today. Atherosclerosis (AS) is a chronic inflammatory disease characterized by thickening or functional degeneration of the arterial wall, and in the later stage of the disease, plaque ruptures to induce thrombosis, which in turn causes ischemia in tissues or organs. It is therefore the pathological basis for all types of cardiovascular diseases. Nuclear transcription factor kappa B (NF-κB), an important nuclear transcription factor in the inflammatory response, is activated to mediate the transcription of inflammatory factors that can trigger or exacerbate the development of AS. Vascular endothelial cells are activated by inflammatory factors. NF-κB mediates related regulatory genes in endothelial cells to secrete adhesion molecules, chemokines, and coagulation factors, promotes selective aggregation of monocytes, up-regulates the expression of adhesion molecules to make adhesion molecules stick to the endothelium and move toward the intima, promotes the degradation of the extracellular matrix, and forms unstable plaques. In recent years, traditional Chinese medicine (TCM) has achieved certain results in the prevention and treatment of AS, and many Chinese medicines have been proved to be effective in resisting AS and can act on multiple targets in the human body, affecting the occurrence and development of AS in different links. This paper mainly introduced the NF-κB pathway and its relationship with AS, reviewed research progress on 75 components of different types in Chinese medicine monomers such as flavonoids, terpenoids, and alkaloids in AS resistance based on the NF-κB pathway, and found that Chinese medicine monomers mainly regulate cholesterol balance, inhibit the inflammatory response, reduce cell proliferation, inhibit intercellular adhesion, and suppress foam cell formation by regulating the NF-κB pathway to provide a reference for the prevention and treatment of AS.

RESUMO

Objective: To investigate the protective effect of compound Longmaining isoprenaline hydrochloride-induced myocardial infarction model and its effect on Toll-like receptor 4(TLR4)/myeloid differentiation factor 88(MyD88)/nuclear transcription factor-kappa B (NF-κB) signaling pathway.Method: Forty-eight male SD rats were randomly divided into 6 groups:normal group,model group,compound salvia miltiorrhiza drop pill group (0.072 9 g·kg-1),and low,medium and high-dose compound Longmaining decoction groups (0.36,0.71,1.43 g·kg-1).The acute myocardial infarction model was induced through subcutaneous injection with isoproterenol.The pathological changes of myocardial tissue were examined by hematoxylin-eosin (HE) staining.The levels of interleukin-1β(IL-1β),interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),monocyte chemotaxis protein-1(MCP-1) and nitrogen (NO) in serum were measured by enzyme linked immunosorbent assay (ELISA).The expression levels of inhibitors of NF-κB kinase subunit-β(IKKβ),NF-κB inhibitor α(IκBα),TLR4,MyD88 and NF-κB p65 were measured by immunohistochemical staining and Western blot.Result: Compared with normal group,the myocardial injury in model group was obvious.The levels of IL-1β,IL-6,TNF-α,MCP-1 and NO in serum increased significantly (PκBα decreased significantly (Pβ,TLR4,MyD88 and NF-κB p65 increased significantly in myocardial tissue (Pβ,IL-6,TNF-α,MCP-1 and NO levels in the serum (PκBα(Pβ,TLR4,MyD88 and NF-κB p65(PConclusion: Compound Longmaining plays a protective effect on acute myocardial infarction by regulatingthe expressions of TLR4/MyD88/NF-κB p65 signaling pathway and relevant inflammatory factors.
