Its drug treatment is highly dependent and has obvious side effects. In this study, dextran sulfate sodium (DSS) was used to establish a mouse model of ulcerative colitis, and Chunpi decoction (10 mL/d) were used for intervention. The body weight, disease activity index (DAI) and colon length of mice were detected, and the liver and kidney function indexes and oxidative stress levels of mice were detected by kits. Enzyme-linked immunosorbent assay (ELISA) was used to detect the levels of inflammatory factors, and the colon tissue sections were observed. Gas chromatography-mass spectrometry (GC-MS) was used to analyze the content of short-chain fatty acids (SCFAs) in the feces of mice. Among the findings: Compared with the DSS group, the body weight and colon length of the mice in the Chunpi decoction intervention group increased, DAI decreased, liver and kidney function improved, the expression of pro-inflammatory factors decreased significantly (P < 0.01), and the expression of anti-inflammatory factors increased significantly (P < 0.01). The level of inflammatory markers were significantly decreased (P < 0.01), the content of SCFAs in feces was up-regulated, and the structure of colon epithelium was improved. Chunpi decoction can improve intestinal mucosal injury and liver and kidney dysfunction in mice, and has a good therapeutic effect on DSS-induced ulcerative colitis in mice.","PeriodicalId":336556,"journal":{"name":"Scientific Journal of Technology","volume":"59 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139251800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to further improve the performance of insulation paint, it is necessary to doping inorganic materials. However, in order to achieve high performance, high doping is generally required, and high doping faces problems such as poor compatibility between doped particles and insulation paint. In order to further improve the flame retardancy, toughness, thermal stability, and wear resistance of insulation paint, researchers generally use the method of doping inorganic particle materials. Research has found that nano inorganic materials (such as nano titanium dioxide) can improve the flame retardancy of materials while also improving their thermal and mechanical properties. However, in order to achieve high performance, insulating paint generally requires high doping, and high doping will face problems such as poor compatibility between doped particles and insulating paint. On the one hand, due to the large size and uneven dispersion of doped particles, it is difficult to achieve a good composite effect; On the other hand, the incompatibility between thermal conductive materials and organic surface interfaces further limits the effectiveness of the material. Therefore, introducing titanium dioxide nanotube materials with smaller dimensions, better dispersibility, and surface hydrophobicity treatment into the insulation paint can improve the compounding effect and further enhance the resistance to ATF oil and flame retardancy of the insulation paint.","PeriodicalId":336556,"journal":{"name":"Scientific Journal of Technology","volume":"20 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139251830","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, in the process of increasing the construction of urban lighting projects, emphasis should be placed on energy conservation and environmental protection, reducing urban electricity expenses, reducing post maintenance of urban lighting projects, and achieving intelligent street lights on the basis of energy conservation and environmental protection. According to the concept of energy conservation and environmental protection, an intelligent street lamp with AT89C52 single chip microcomputer as the core component is designed. Intelligent components (Photoresistor, etc.) are used to realize the acousto-optic control of street lamp lighting. In the daytime, the light of the strong light signal identified by the photosensitive resistor is extinguished. When the light is dark at night, the street lamp lighting is controlled by the voice control recognition system. The light is dim when there are no people and vehicles. When people and vehicles are identified, the light brightness is improved to realize the automatic control of light, Maximize the conservation of electricity resources.","PeriodicalId":336556,"journal":{"name":"Scientific Journal of Technology","volume":"2014 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132825789","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
