RESUMO
Precancerous lesions of gastric cancer (PLGC) is a pathological change accompanied by intestinal metaplasia and dysplasia on the basis of chronic atrophic gastritis. It is also an important stage of "inflammation-cancer transformation" on gastric mucosa. Paying attention to the intervention of PLGC has important value and significance for the secondary prevention of gastric cancer. PLGC has the characteristics of occult onset, toxin damaging collaterals, and long course of disease, which is highly consistent to the pathogenesis characteristics of incubative pathogenic factors. Based on the relevance of incubative pathogenic factors and PLGC, treatment of PLGC from the perspective of incubative pathogenic factors should be mainly strengthening the spleen and stomach, and combined with the methods of regulating qi and dissipating dampness, and removing blood stasis and detoxification. It should also pay attention to the prognosis.Paying attention to the body-mind treatment can reduce the re-occurrence , so as to provide a new way of thinking for treating PLGC from incubative pathogenic factors.
RESUMO
Objective:The mechanism of Indigo Naturalis in the treatment of ulcerative colitis (UC) was predicted by GEO chip combined with network pharmacology, and preliminarily verified by molecular docking. Methods:The main active components and targets of Indigo Naturalis were obtained by searching TCMSP, SymMap database, SwissTargetPrediction and Pharmmapper. The UC disease targets were obtained from DrugBank database, OMIM database, TTD database, Disgenet database and GEO gene chips. Venn diagram was used to show drug-disease common targets. The protein-protein interaction (PPI) network of intersection targets was analyzed by String platform, and Cytoscape 3.8.2 software was used to construct the PPI network of components and disease targets. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis were performed on the core targets. AutoDock Vina 1.2.1 was used for molecular docking, and the results were visualized by Discovery studio Visualizer. Results:A total of 10 active components and 184 compound targets of IN-UC, of which 42 were core targets, were enriched and analyzed by GO and KEGG. The therapeutic effect of Indigo Naturalis on UC may involve activation of various process, such as reactive oxygen species metabolism, heme binding, protein phosphatase binding, secretory granule exocytosis, cytoplasmic vesicles, cell focal adhesion and cell substrate connection, and regulates PI3K/Akt signal pathway, human cytomegalovirus infection signal pathway, EB virus infection signal pathway HF1 signaling pathway and insulin resistance signaling pathway to treat UC. Conlusion:Indigo Naturalis has the characteristics of multi-component, multi target and multi pathway in the treatment of ulcerative colitis. Through PTGS2, CAT and other core targets, it can regulate PI3K/Akt signal pathway, human giant cell signal pathway, HIF-1 signal pathway to play a therapeutic role.
RESUMO
Upper gastrointestinal hemorrhage (UGH) is a kind of intensive disease commonly encountered clinically. In recent years, the diagnosis and treatment method of UGH had achieved satisfied progress. But with the development of aged tendency of population, its morbidity is still in a high level. Especially in older patients with serious complications, the fatality rate is much higher. It has been proved practically, traditional Chinese medicine (TCM) has remarkable effects in treating UGH. This article summarized the progress of TCM or integrative medicine studies on UGH through etiology and pathogenesis, therapeutic principle and methods.
