The invention provides an application of 10E, 12Z-octadecadienoic acid in inhibition of inflammatory reactions, and the inflammatory reactions comprise macrophage inflammatory reactions induced by lipopolysaccharide. According to the invention, a mouse mononuclear macrophage RAW264.7 cell inflammatory response model is constructed. The method comprises the following steps: firstly, measuring CC50 of 10E, 12Z-octadecadienoic acid by a CCK-8 method; 10E, 12Z-octadecadienoic acid is used for pretreating macrophages for 24 hours before lipopolysaccharide stimulation at the final concentration of 25 mu mol / L to 100 mu mol / L, qPCR (quantitative polymerase chain reaction) and ELISA (enzyme-linked immuno sorbent assay) experiments prove that the 10E, 12Z-octadecadienoic acid plays an anti-inflammatory role by inhibiting mRNA (messenger ribonucleic acid) expression and protein secretion of IL-6, IL-1beta and / or TNF-alpha, and the anti-inflammatory effect is optimal at the final concentration of 100 mu mol / L. The 10E, 12Z-octadecadienoic acid is a single unmodified fatty acid isomer, is clear in structure, good in anti-inflammatory effect repeatability and good in biocompatibility, and can reduce adverse reactions compared with traditional anti-inflammatory drugs; compared with existing fatty acid anti-inflammatory components, the composition is clear in component and simple and convenient to prepare. The application scenarios of the invention cover the development of anti-inflammatory drugs, functional foods and biological agents.

A method to synthesize a silver nanohybrid material. The method includes mixing a nitrate solution with a citrate solution to form silver nanoparticles (AgNPs). The method further includes esterifying a first mixture including octadecanoic acid, octadec-9-enoic acid, and octadeca-9,12-dienoic acid with caffeic acid in the presence of an acid catalyst and a solvent to form an unsaturated carboxylic acid mixture including first, second, and third acrylic acid derivatives. The method includes reacting the unsaturated carboxylic acid mixture with ethylene glycol to form a second mixture including first, second, and third ester derivatives. The method further includes mixing the AgNPs with the second mixture to form a third mixture. The method includes evaporating water from the third mixture to form the silver nanohybrid material. The silver nanohybrid material includes a AgNP core covered with the first, second, and third ester derivatives bonded to the AgNP core.

The application discloses a wheat Tilletia indica-specific biomarker combination, a screening method and application thereof, and the biomarker combination comprises 20-hydroxyarachidonic acid, 1-octadecyl lysophosphatidic acid, linolenic acid, 13-hydroxydocosahexaenoic acid, 4-methoxy estrone, hypoxanthine, 3-hydroxymyristic acid, beta-ecdysterone, 17-phenyltrinorprostaglandin F2 alpha cyclopropylmethylamide, 11,12-dihydroxyeicosatrienoic acid and oxidized octadecadienoic acid. When the biomarker combination is used for identifying Tilletia indica, the time-consuming long and the accuracy easily interfered by the spore development stage limitations of traditional morphological identification are overcome; in view of the molecular level identification difficulty caused by the high genome homology of Tilletia indica and Tilletia controversa, the application digs the feature difference at the level of metabolomics, and constructs a specific chemical fingerprint, so that the technical bottleneck that the close relatives are difficult to accurately distinguish is effectively solved.
