The present invention relates to a composition for enhancing memory and preventing, ameliorating or treating cognitive impairment, comprising, as an active ingredient, a complex of Atractylodes macrocephala and Rumex acetosa extracts. The complex of Atractylodes macrocephala and Rumex acetosa extracts not only promotes CREB phosphorylation in hippocampal neurons, but also has a cytoprotective effect in brain neuronal cell lines, affects synapse remodeling at neuronal terminals that occurs during long-term potentiation (LTP), thereby increasing protein expression levels of synaptic remodeling factors and neuroplastic factors, and has been confirmed to improve short-term / long-term memory ability in behavioral evaluation of animal models, and thus can be effectively used as a health functional food, a medicine, or a feed additive, for enhancing memory and preventing, ameliorating or treating cognitive impairment.

The present invention provides a traditional Chinese medicine composition for treating children with autism spectrum disorder, which is composed of the following components in parts by weight: 1-3 parts of arachidonic acid; 1-3 parts of phosphatidylserine; 1-3 parts of nervonic acid; 8-12 parts of Poria cocos; 1-3 parts of saffron; 1-3 parts of carob; 1-3 parts of sword bean; 7-10 parts of Rumex acetosa; 8-12 parts of honeysuckle. The pharmaceutical composition of the present invention has a simple formula and a definite effect, and has a good effect of reducing the scores of the Childhood Autism Rating Scale (CARS), the Autism Behavior Checklist (ABC scale) and the Assessment of Treatment Effects in Children (ATEC), with a high total effective rate, and the longer the persistence time, the better the curative effect. Through long-term toxicity animal experiments, it has high safety. Through relevant animal experiments, it can effectively improve the social interaction ability disorder, repetitive stereotyped behavior, narrow interest activities, learning and memory ability, etc. of autism.

This invention discloses an improved breeding method for leafy grasses. Using Rumex (hybrid sorrel, abbreviated as Rumex) as the female parent and Rumex rubrotinctum (commonly known as Rumex 'sheep's hoof') as the male parent, a first-generation leafy grass hybrid is obtained. This first-generation hybrid is backcrossed with Rumex to obtain a first-generation backcross. This first-generation backcross is then subjected to 3-4 generations of self-pollination. Through marker-assisted selection and agronomic trait identification, genetically stable leafy grasses without phenotypic segregation are obtained. Finally, improved original seed varieties are obtained through primary seed propagation. The newly added combination of directional backcrossing + multi-generation self-pollination + marker-assisted selection in this invention is the first such disclosure in the field of leafy grass breeding. The leafy grasses obtained by this breeding method have a protein content ≥35%, a 20% increase in salt and alkali resistance, and a genetic stability of over 98%. The breeding process is clearly defined with quantified parameters, allowing for large-scale propagation. It overcomes the technical shortcomings of traditional hybrids and is suitable for commercial cultivation of leafy grasses, possessing significant economic and application value.

The present invention discloses a rhizosphere bacterium PLr56 of Rumex acetosella, a phosphorus-enriched plant, and its application, belonging to the technical field of microbiology. This strain is Enterobacter chuanxiongensis Enterobacter chuandaensis PLr56, which was deposited at the General Microbiology Center of the China Committee for Culture Collection of Microorganisms on July 25, 2024, with the deposit number CGMCC NO: 31461. It is a rhizosphere bacterium with the functions of adapting to low available phosphorus, tolerating high available phosphorus, and promoting plant growth. Due to its growth-promoting abilities such as dissolving tricalcium phosphate and calcium phytate, nitrogen fixation, secreting indole acetic acid, and producing siderophores, it can promote plant growth and the accumulation of nitrogen and phosphorus in plants.
