In severe cases, it can lead to septic shock and pose a threat to life. Developing and preparing a material that has adhesiveness in a wet environment such as the surface of the stomach is a challenge. Therefore, we have successfully prepared a hydrogel membrane with wet adhesiveness. This hydrogel membrane is composed of glutaraldehyde-crosslinked polyvinyl alcohol (PVA) hydrogel modified by 3,4-dihydroxyphenylalanine (DOPA). The side chains of PVA molecules modified with DOPA achieve wet adhesion through the formation of hydrogen bonds between the catechol groups and the surface of the tissue substrate. It is used for suture-free repair of damaged gastric epithelium. According to the results of mechanical experiments, its wet adhesion lap shear strength to gastric tissue reaches 34.8 kPa, and the peeling strength reaches 24.5 kPa. The results of <em>in vitro</em> cell experiments show that the hydrogel has good biocompatibility. The hydrogel prepared by this simple method demonstrates adaptability to the gastric environment, making it promising for applications in gastric wound repair.</div></div>","PeriodicalId":277,"journal":{"name":"Chinese Journal of Analytical Chemistry","volume":"53 10","pages":"Article 100581"},"PeriodicalIF":1.3,"publicationDate":"2025-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144890588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional Chinese medicines systems pharmacology (TCMSP), Uniprot and Swiss Target Prediction databases were used to obtain compound and target information for EP.

Molecular docking and kinetic simulation studies confirmed that the core components effectively bind to the above targets, meanwhile, <em>in vivo</em> and <em>in vitro</em> experiments showed that the core components have better hypoglycemic activity compared with the positive control. In conclusion, the therapeutic effects of EP in DM may be attributed to its bioactive components, such as icaritin and icariin.

This study explores the impact of altitude on its metabolic profile using an integrated Liquid Chromatography-Mass Spectrometry (LC-MS) and Gas chromatography-mass spectrometry (GC–MS) metabolomics approach. Samples from four altitudes (∼1231 to ∼3200 m) were analyzed and revealed distinct metabolic variations across samples from different altitudes. To facilitate data analysis, we developed Statistical Metabolomics Suite (StatMS), a Python-based tool that provides preprocessing, statistical analysis, and interactive visualization. By integrating experimental analysis with data processing, this study offers new insights into the environmental influence on <em>C. tinctoria’s</em> metabolic composition, enhancing its potential as a high-value medicinal resource.</div></div>","PeriodicalId":277,"journal":{"name":"Chinese Journal of Analytical Chemistry","volume":"53 9","pages":"Article 100569"},"PeriodicalIF":1.2,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144713425","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
