This invention discloses an aluminum-cobalt bimetallic ionic liquid-modified biochar catalyst, its preparation method, and its application, belonging to the technical field of water pollution control and environmental functional materials. The method involves mixing an aluminum-cobalt bimetallic ionic liquid with biomass raw materials, followed by one-step or two-step pyrolysis, then cooling, washing, and drying to obtain the aluminum-cobalt bimetallic ionic liquid-modified biochar catalyst. This method eliminates the need for prior preparation of a biochar precursor followed by secondary loading, enabling simultaneous pore formation, nitrogen doping, aluminum-cobalt bimetallic active site construction, and metal-oxygen coordination structure formation of biochar in a single pyrolysis process. The process is simple, and the raw materials are readily available. The resulting catalyst possesses a high specific surface area, abundant surface defects, and stable aluminum-cobalt synergistic active sites, enabling efficient activation of persulfate and rapid degradation of norfloxacin under near-neutral conditions. It also exhibits good anti-interference properties, cycle stability, and potential for practical water body application.

The invention discloses a Wnt signal path adjusting system and a method for activating a Wnt signal path. The Wnt signal channel regulation system comprises a first regulator and a second regulator, each regulator comprises an I structural domain and an II structural domain, the first regulator comprises an I-1 structural domain and an II-1 structural domain which are respectively targeted to Wnt receptors Frizzled and LRP6, and the second regulator comprises an I-2 structural domain and an II-2 structural domain which are respectively targeted to Wnt receptors Frizzled and LRP6; the first regulator is different from the second regulator. The Wnt signal channel regulation system provided by the invention has the advantages of high activation capability, small toxic and side effects and selectivity in Wnt signal channel activation, and has a good application prospect.

The hyaluronic acid derivative into which a steroid group has been introduced according to the present invention has an area (A1) / (A2) ratio of 0.90 or more, said area (A1) / (A2) being calculated by the following method from a chromatogram obtained by gel permeation chromatography measurement. Program from intersection (Ub) of vertical line demarcated from point (Kb) of maximum refractive index intensity on chromatogram of reference substance 50kDa polyacrylic acid to baseline (B) and chromatogram of hyaluronic acid derivative to end point of chromatogram of hyaluronic acid derivative, vertical line demarcated from point (Kb) of maximum refractive index intensity to baseline (B), and baseline (B) the value of the enclosed area is A2; a value of an area enclosed by the baseline (B) and a perpendicular line drawn from the refractive index intensity maximum point (Kb) to the baseline (B) in a curve from a start point of the chromatogram of the hyaluronic acid derivative to the intersection point (Ub) is set as A1.
