Resumen de: CN120047411A
The invention provides a method for assisting in identifying ulcerative colitis inflammatory activity levels based on dynamic graph multi-instance learning. The method comprises the steps of data acquisition, data preprocessing, dynamic graph multi-instance learning model construction of inflammatory activity level diagnosis and model evaluation. The data acquisition mainly comprises the steps of collecting pathological images of a patient with ulcerative colitis, digitalizing the pathological images through a digital scanner, excluding a part of pathological images containing problems such as blurring, fading and abnormal staining, and finally determining a grading label of each pathological image by a deep gastrointestinal pathology expert. The data preprocessing mainly comprises the steps of processing a digital pathological image, converting the digital pathological image into image blocks, then extracting features from each image block by using a visual basic model, and finally constructing a dynamic graph multi-instance learning model for training. According to the method, exploration of the internal relation of the image blocks input to the WSI is promoted, and the prediction effect of the model is improved.

The present invention relates to a dual PRR-inhibiting peptide system consisting of TLR4- and RAGE-inhibiting motifs derived from S100A8 and S100A9 and conjugated with a CT peptide for colon-specific delivery. In human-derived monocyte THP-1 and mouse bone marrow-derived macrophages (BMDMs), S100A8/A9-derived peptides including TLR4 and RAGE-interacting motifs inhibit the binding of S100 to TLR4 or RAGE and the activation of the NLRP3 inflammasome in a dose-dependent manner. When the peptide according to the present invention is injected into mouse models of acute and chronic colitis, survival is significantly increased, and pathological damage to the colon is alleviated. In a mouse model of colitis-related colorectal cancer, when the peptide according to the present invention is injected, body weight is increased, tumor burden in the distal colon is decreased, and histological colon damage is significantly alleviated. When the peptide according to the present invention is injected into an oxaliplatin-resistant CRC xenograft mouse model, EMT-associated markers are reduced in tumor tissues and tumor growth is significantly inhibited.

To provide a therapeutic drug for inflammatory diseases, particularly inflammatory bowel disease, that has no serious side effects such as immunosuppression.SOLUTION: From an analysis of the mechanism of action of sulfasalazine, it has been revealed that an anti-inflammatory action occurs by increasing intracellular glutamate. An xCT inhibitor or a glutamine synthetase inhibitor that increases intracellular glutamate has been found to be effective in the treatment of inflammatory bowel disease. Furthermore, it is considered that a compound that suppresses the expression of xCT or a glutamine synthesis-inhibiting enzyme also has a therapeutic effect.SELECTED DRAWING: Figure 5D
