According to the plasma aquaculture water purification method and system, a cold plasma directional screening technology is used as a core to construct a cold plasma water treatment module, a nanosecond pulse plasma generator is used for exciting a gas medium to form cold plasma, active particles are screened in situ through a directional screening assembly, and the cold plasma water treatment module is used for purifying aquaculture water. The method comprises the following steps: introducing ammonia nitrogen into a water body, guiding < 1 > O2 to be quickly injected into the water body, instantaneously completing a primary purification reaction in a gas-liquid intersection chamber, further, in order to fully utilize residual active particles, directionally converting a reaction precursor O3 of < 1 > O2 into < 1 > O2 through a catalytic dissociation module, and completing a secondary purification reaction between the < 1 > O2 and the ammonia nitrogen. Ammonia nitrogen is directionally converted into nitrogen by utilizing a 1O2-dominated non-free radical reaction path, the content of ammonia nitrogen and total inorganic nitrogen in a water body is reduced, and after purification is completed, oxidizing components in the water body and tail gas are respectively removed by adopting a by-product removal assembly, so that the use safety is guaranteed.

The application discloses a two-compartment modeling and prediction method for sodium kinetics in hemodialysis. The method divides the patient's body fluid into two compartments of extracellular fluid and intracellular fluid, and establishes a coupled differential equation set to describe the sodium transfer kinetics in the dialysis process. The application corrects the physical error of the existing model in the dispersion equilibrium concentration formula, proposes C_eq=[Na]d / σ (σ=0.97 is the Gibbs-Donnan factor) to replace the traditional Donnan formula and the old recommended formula, eliminates the false dispersion gradient under the condition of isonatric dialysis based on the physical fact that electrolytes are only distributed in the plasma water phase, and removes the error solvent drag term by clearly defining the biophysical constraints of the cell membrane aquaporin not transporting sodium. The application adopts a perturbation reference model to replace the traditional Fick diffusion law to describe the cell membrane sodium exchange, and more accurately reflects the intracellular and extracellular sodium kinetics. The model can accurately predict the serum sodium change and sodium removal under different dialysis prescriptions, and can generate a sodium removal contour map for clinical prescription optimization.

This invention provides a hydrogel for treating atopic dermatitis and its applications, relating to the field of biomedical technology. The hydrogel comprises SA, plasma water, L-G2, and / or FLA. Preliminary evaluation of the hydrogel was conducted through in vitro cytotoxicity and antibacterial performance tests, confirming its ability to inhibit Staphylococcus aureus and Escherichia coli. Simultaneously, the hydrogel exhibits low cytotoxicity, meeting the basic requirements for biomedical dressings. In animal experiments, by comparing skin lesions before and after treatment in AD mice, the hydrogel was observed to significantly improve skin lesions on the back of mice, demonstrating good anti-inflammatory effects. Pathological histological analysis showed that the hydrogel can reduce epidermal thickness, inhibit the increase in TNF-α levels induced by DNCB, and promote inflammation relief. Simultaneously, SA can provide a moist healing environment for skin wounds, helping to promote wound repair. Therefore, this hydrogel provides a new strategy for the treatment and management of AD and is expected to become a novel topical drug for AD treatment.
