The invention discloses a method for improving the quality of Scutellaria baicalensis by using sodium dithionite, which relates to the technical field of Scutellaria baicalensis. The preparation method is as follows: fresh roots of scutellaria baicalensis→cleaning→drying in the shade at 20-25°C for 1-2 days→spraying active oxygen Carrier → placed at 20-25°C for 3-10 days → dry; the active oxygen carrier is sodium dithionite, the concentration of sodium dithionite is 0.4μmol / L-40mmol / L; the treatment time period is 3-15 day; the temperature is 10-35°C; the present invention plants Chinese herbal medicines in the most suitable plant growth area or in the main production area, and various measures can be taken to increase the yield; according to the nature of the quality of Scutellaria baicalensis, artificially Intervene in the secondary metabolism of fresh medicinal materials, greatly improve the quality of medicinal materials, so as to achieve a double harvest of quality and yield. The invention maximizes the level of secondary metabolism of Scutellaria baicalensis, so that all the medicinal materials produced can reach or exceed the quality of authentic medicinal materials.

The invention discloses an application of alpha-ketoglutaric acid to improvement of animal reproduction function deficit caused by high fat diet, and provides a novel application of the alpha-ketoglutaric acid. Abnormity of animal estrus cycle, ovarian morphology and functions and sex hormone secretion caused by high fat diet can be remarkably improved by the alpha-ketoglutaric acid, animal reproduction function deficit caused by high fat diet is further improved, and particularly, estrus cycle disorder, corpus luteum number depletion, theca cell thickness increase, follicle-stimulating hormone content reduction and luteinizing hormone content rise caused by high fat diet are improved by the alpha-ketoglutaric acid, so that animal reproduction function deficit caused by high fat diet can be remarkably improved. Moreover, the alpha-ketoglutaric acid is free from substances harmful to animals or human bodies, adding quantity is small, and the alpha-ketoglutaric acid can be directly added into animal drinking water, feed, food or drugs, has the advantages of safety, effectiveness, no toxic and side effects and the like and has a good popularization and application prospect in improvement of animal reproduction function deficit caused by high fat diet.

The invention discloses Prussian blue analog nanoparticles. The nanoparticles are formed by using Prussian blue analog nanoparticles as the core and coating organic high-polymer surface protectants polyvinylpyrrolidone / chitosan and hyaluronic acid on the nanoparticle surface. The preparation method of the Prussian blue analog nanoparticles comprises the following steps: S1. preparing a mixed solution containing a zinc salt, ferrous sulfate, an iron salt and an organic high-polymer surface protectant; S2. stirring at room temperature for 30 minutes to 2 hours, putting the solution into a dialysis bag filled with distilled water, and dialyzing for two days; and S3. taking out the solid matter, and collecting the solid product by freeze-drying. The Prussian blue analog nanoparticles are used in cancer targeted therapy. The Zn-FePB NPH drug is very safe. The copper element in cancer cells can be replaced to achieve the goal of starving the cancer cells. PVP (or chitosan) doping is carried out on the basis of the high targeting action of the hyaluronic acid to better regulate the size of the nanoparticles.
