This invention belongs to the field of pharmaceutical technology, and relates to the use of a combination of sour cherry powder and celery seed powder, and complexes containing this composition. Specifically, the sour cherry powder and celery seed powder composition is used in the preparation of drugs for treating or regulating intestinal flora imbalance caused by hyperuricemia. The preparation method of this composition is as follows: pitting sour cherries, freezing them separately with liquid nitrogen, grinding them into powder using a pulverizer, and sieving them separately to obtain sour cherry powder and celery seed powder; mixing the obtained sour cherry powder and celery seed powder at a ratio of (0.5~3):1. This invention discusses the diversity, richness, and evenness of intestinal flora through diversity analysis, community bar chart analysis, and Venn diagram analysis. The results show that this composition can increase beneficial bacteria (Prevotella, Mulliez, Lactobacillus, etc.), reduce harmful bacteria (Alternaria), improve the structure of intestinal flora, and maintain the balance of intestinal flora.

This invention provides a strain of *Lactobacillus plantarum*, and discloses the fermentation product of *Eucommia ulmoides* leaves, *Rehmannia glutinosa*, dried ginger, and *Dendrobium officinale* obtained by fermenting these herbs, along with its preparation method and applications. This fermentation product can directionally activate the phenylpropane biosynthetic pathway, inducing the generation of characteristic small molecule metabolites of polyphenols, particularly sanguranyl sulfadiazine (SSA). Moreover, compared to the raw materials, the fermentation product contains more active small molecule metabolites. Finally, experiments on zebrafish modeled with prednisone demonstrated that the fermentation product can significantly promote bone formation. The fermentation product mainly restores the expression levels of related genes to normal zebrafish gene expression levels by regulating these genes. Therefore, the fermentation product can be used to prepare foods or medicines that improve bone health.

The application discloses a DNA sulfur-modified bacillus subtilis and application thereof in alleviating alcoholic diseases, and relates to the field of biochemistry.The application provides a DNA sulfur-modified bacillus subtilis, which is named as Bacillus subtilis E10-1 and has a preservation number of CCTCC NO: M20253036.It is verified through animal experiments that the DNA sulfur-modified bacillus subtilis E10-1 is more resistant to alcohol than a strain in which sulfur modification is knocked out, can reduce the levels of indexes such as glutathione pyrotransaminase, glutathione transaminase and urea nitrogen in serum of a host after drinking alcohol, and the level of interferon gamma, can increase the levels of total protein, superoxide dismutase and glutathione peroxidase, can alleviate oxidative stress damage caused by alcohol, can reduce inflammatory reactions of various organ tissues, can maintain normal physiological functions of cells, can repair intestinal barriers, and can maintain intestinal flora homeostasis, so that alcoholic related diseases can be prevented and / or treated.

The application discloses a method for removing antibiotic resistance genes in straw sludge compost and application thereof, and belongs to the technical field of composting. In order to remove antibiotic resistance genes in municipal sludge, the application provides a method for removing antibiotic resistance genes in straw substrate sludge compost, specifically, antibiotic resistance genes are removed through combined action of strong oxidation and high temperature in aerobic composting. The method significantly reduces the abundance of antibiotic resistance genes in the compost sample on the basis of traditional aerobic composting technology, and reduces the potential risk of human health caused by recycling of the compost product in combination with an ozone oxidation technology and corn straw as a carbon source.

The invention belongs to the technical field of biological medicines, and relates to application of a histone deacetylase inhibitor HDACi in preparation of a medicine for preventing and / or treating hyperammonemia-induced encephalopathy. According to the invention, a histone deacetylase inhibitor HDACi is used as a new medicine, the HDACi can enter a central nervous system, and the GS is triggered to be degraded through a proteasome mediated by CRBN E3 ubiquitin ligase by improving the acetylation level of a key enzyme, namely glutamine synthetase (GS), of astrocytes, so that the GS protein abundance is reversibly reduced, and the GS protein abundance is reduced. The application has the advantages that pathological accumulation of toxic metabolite glutamine can be reduced from the source, cerebral edema, autophagy-lysosomal dysfunction, neuroinflammation and neuron injury caused by the pathological accumulation can be synchronously improved, severe neurotoxicity such as persistent enzyme inhibition and acute epilepsy caused by irreversible inhibitors such as MSO can be avoided, clinical transformation risks can be obviously reduced, and the safety is high.
