This invention provides a nutritional composition rich in A2-β-casein that promotes calcium absorption, belonging to the field of functional foods. The invention obtains A2-β-casein through genotyping and purification, and then combines it with colostrum basic protein and a small amount of milk-derived calcium to form compositions with different ratios. This invention utilizes a Caco-2 cell model to study the fluorescence imaging of calcium ion influx into Caco-2 cells, the calcium absorption-promoting activity, and the absorption pathway, thereby comprehensively evaluating the calcium absorption characteristics of this composition and obtaining a nutritional composition rich in A2-β-casein that promotes calcium absorption.

This research relates to the biomedical field and describes a thermosensitive hydrogel loaded with ginger extracellular vesicles and tannic acid, its preparation method, and its application in the preparation of anti-infective drugs. The process includes extracting ginger-derived extracellular vesicles; loading tannic acid onto these vesicles to obtain TA@GDEVs; preparing SP hydrogels; and slowly adding TA@GDEVs to the SP hydrogel to form a GTSP hydrogel system. GDEVs exhibit anti-inflammatory and pro-repair activities; TA provides broad-spectrum antibacterial, anti-inflammatory, and antioxidant functions; the SP hydrogel endows the thermosensitive hydrogel composite system with injectable and in-situ gelation properties; the SP hydrogel not only provides in-situ gelation and a protective barrier for GDEVs and TA but also enables controlled release of the loaded material; through synergistic effects, the three components enable the thermosensitive hydrogel composite system to possess responsiveness to the infection microenvironment, enhanced antibacterial efficacy, immune remodeling, and tissue repair functions, demonstrating its potential as a multifunctional anti-infective wound repair material.

This invention relates to the field of medical drainage and fluid management technology, and discloses a multi-channel drainage management device, including a main drainage pipe, a support base, a channel adjustment mechanism, and multiple adjustable peristaltic pumps. Multiple branch pipes correspond to flushing, drainage, and drug administration channels respectively, and are selectively connected to the main drainage pipe through the channel adjustment mechanism. The channel adjustment mechanism employs a rotational selection and positioning limit structure to achieve stable switching of channel connectivity under different operating conditions. Each branch pipe is equipped with a flow sensor and a pressure sensor for real-time monitoring of the pipe's internal conditions and, in conjunction with the main controller, adjusts the operating state of the peristaltic pumps. The peristaltic pumps feature an adjustable squeezing structure and incorporate a manual adjustment mechanism to adapt to pressure and flow control requirements under different fluid conditions. This device enables integrated management of flushing, drainage, and drug administration functions, has a compact structure, and provides reliable channel switching, which helps improve the safety and stability of clinical operations.
