This invention belongs to the field of card production technology, and particularly relates to a precision screen-printed card and its manufacturing process. A precision screen-printed card includes: a card substrate, the surface of which is provided with a precision screen-printed graphic layer. The precision screen-printed graphic layer is formed by screen printing with high-viscosity raised-letter ink through a high-mesh precision screen. The line width of the precision screen-printed graphic layer is 0.05mm-0.08mm, and the precision screen-printed graphic layer has a perceptible three-dimensional raised structure. This achieves stable reproduction of fine lines, is suitable for various card substrates and other processes, making the cards more exquisite and reducing production costs.

This invention relates to animal models and their applications, specifically to a method for constructing a spontaneous mouse cerebral edema model and its application. This invention utilizes PEN2... fl / + Mice and PEN2 fl / + Mice were mated to obtain PEN2. fl / fl Homozygous mice; then the obtained PEN2 fl / fl Mice and hGFAP Cre / + Mice were mated to obtain PEN2. fl / + hGFAP Cre / + Mice; the final PEN2 obtained fl / + hGFAP Cre / + Mice and PEN2 fl / fl Mice were mated to obtain PEN2. fl / fl hGFAP Cre / + The mouse model is a spontaneous mouse cerebral edema model. In this model, PEN2 protein levels are significantly downregulated, and the mouse exhibits a severe cerebral edema phenotype. This model can be used to establish a cerebral edema drug screening platform. It can also be used for research on cerebral edema-related diseases, such as the pathogenesis of cerebral edema caused by infection, glioma, and traumatic brain injury, as well as for the development of technologies and products for the diagnosis and treatment of related diseases.

This invention discloses an aroma fitter for fenugreek tincture based on key aroma components and synergistic aroma characteristics, and its applications. Based on analytical studies of the aroma components and aroma characteristics of high-quality fenugreek tincture, the aroma fitter identifies key aroma characteristics such as caramel sweetness, freshness, fruitiness, nutty aroma, roasting aroma, and sourness, and determines the contributing characteristic compounds and their synergistic proportions within each aroma characteristic. The composition contains key components such as acetic acid, trans-2-pentenal, propyl butyrate, phenethyl acetate, 2-hexanone, ethyl palmitate, benzaldehyde, 2,5-dimethylpyrazine, and 3-hydroxy-4,5-dimethyl-2(5H)furanone, which are precisely formulated to achieve a high degree of consistency with natural fenugreek tincture in aroma structure and olfactory characteristics. This invention not only provides a realistic and layered aroma fitter formulation but can also be applied to the food and daily chemical industries, providing stable and harmonious fenugreek characteristic aromas, thus possessing significant practical application value.
