The application discloses a compound plant essential oil preparation for improving intestinal tract barrier function of laying hens and a preparation method thereof, relates to the technical field of livestock and poultry intestinal tract health regulation, and comprises microcapsule particles with a multilayer structure, which sequentially comprises a core layer, a first coating layer, an intermediate functional layer and a second coating layer; the compound plant essential oil preparation for improving intestinal tract barrier function of laying hens and the preparation method thereof are characterized in that the preparation is arranged as a multilayer microcapsule structure composed of the core layer, the first coating layer, the intermediate functional layer and the second coating layer in sequence, and the first coating layer and the second coating layer adopt enteric polymers with different pH dissolution ranges, so that the intermediate functional layer can be released first in the pH environment from the duodenum to the jejunum, and the core layer is released subsequently in the pH environment of the ileum, thereby realizing the graded and zoned release of active components of plant essential oils in the front and rear sections of the small intestine of laying hens, and matching different essential oil components with the barrier repair requirements of each section of the intestinal tract.

The application belongs to the technical field of biological medicine, and particularly relates to application of a CLIC5 gene in preparation of a drug for preventing and / or treating intestinal inflammation. The application provides application of the CLIC5 gene in preparation of a drug for preventing and / or treating intestinal inflammation, wherein a nucleotide sequence of the CLIC5 gene is shown as SEQ ID NO:1. The application finds that intestinal epithelial cell-specific knockout of the CLIC5 can reduce a serum endotoxin level, improve intestinal epithelial barrier function, increase a content of butyric acid, reduce a serum inflammatory factor level, and also reduce a gene expression level of an inflammatory factor in an ileum and a colon. The application first discloses that intestinal epithelial cell-specific knockout of the CLIC5 can effectively prevent or treat intestinal inflammation and reduce a body inflammatory factor level, thereby providing a new target and method for treating human intestinal inflammation.

This invention provides a process for preparing ileal-targeted empty capsules, relating to the field of pharmaceutical excipients technology. The process includes the following steps: preparing the following raw materials: gelatin, titanium dioxide, and sodium stearate; dissolving the gelatin in water at 60-70°C, heating and stirring, adding titanium dioxide and sodium stearate, mixing well, and allowing to stand to obtain a film-forming gel. This invention utilizes a preparation mechanism involving the mixing of water-soluble polyacrylic acid resin IV, polyacrylic acid resin III, and polyvinyl alcohol, with the remaining materials added in steps, to achieve the predetermined goal of ileal disintegration. Furthermore, based on the synergistic effect of polyacrylic acid resin III with water-soluble polyacrylic acid resin IV and polyvinyl alcohol, the drug release rate of the empty capsule is improved, allowing the drug to rapidly reach an effective concentration in the ileum and exert its therapeutic effect more effectively.

The application discloses a pig breed disease resistance breeding screening method based on taurine cholate metabolic markers, and belongs to the technical field of animal breeding. The application effectively screens the breeding pigs with stronger intestinal barrier function by establishing a breeding standard based on the intestinal barrier function difference, especially taking the taurine cholate level as a key index, and improves the health level and production benefit of pigs. Compared with the prior art, the ileum villus height to crypt depth ratio of the breeding pig is increased by 25.3%, the mRNA relative expression amount of ZO-1 and other tight junction proteins is increased by 32.7%, the SIgA and IgG levels are increased by 38.5%, the health level of the pig is significantly improved, and the production benefit is increased by 15.6%.

The invention discloses a double layered delayed-release hard capsules made by double dipping, that is by two consecutive dip molding steps with the same mold pin without removing the film, provided by the first dip molding step, from the mold pin between the two dip molding steps, but dipping the mold pin with this first film on the mold pin in the second dip molding step, each dip molding step is done with a different polymer melt, providing a double layered delayed-release capsule, which passes the stomach and the jejunum and opens in the ileum.

The application discloses a strain capable of promoting vitamin B 12 absorption and improving cognitive function, and application thereof, and belongs to the technical field of biotechnology. The application provides a Paraglactobacillus paracus CCFA1525, which is preserved in the Guangdong Microbial Culture Collection Center, and has a preservation number of GDMCC No: 67380 and a preservation date of November 18, 2025. The Paraglactobacillus paracus CCFA1525 can up-regulate the expression of key proteins in the ileum, promote the absorption of vitamin B 12 , relieve nerve damage and cognitive impairment caused by sleep deprivation, and thus plays a significant neuroprotective role. Therefore, the Paraglactobacillus paracus CCFA1525 can be used for developing products with anti-nerve damage function, and is suitable for improving cognitive impairment caused by vitamin B 12 absorption disorder, and has good functional application prospect and industrial production potential. 12 ​
