The invention relates to the technical field of preparation of wrinkled mulching film paper, in particular to a preparation method of wrinkled mulching film paper suitable for rice sowing by an unmanned aerial vehicle, and the preparation method of the wrinkled mulching film paper comprises the following steps: S1, preparing wrinkled core paper from waste paper through a papermaking process; s2, spraying and coating the wrinkled core paper obtained in the step S1, forming an organic coating layer on the surface layer of the wrinkled core paper, and drying to form original mulching film paper; and S3, coiling the original mulching film paper obtained in the step S2 to prepare a finished mulching film paper product. The unmanned aerial vehicle has the effect of solving the problem that after rice is sown by the unmanned aerial vehicle, weed growth still needs to be controlled in a pesticide spraying mode, and consequently food safety and soil pollution are harmed.

The invention discloses a human placenta-derived endothelial progenitor cell and a combined drug thereof as well as application of the human placenta-derived endothelial progenitor cell in preparation of a drug for treating radiation-induced thymus injury, and discloses a novel cell treatment drug for reconstructing a thymus microenvironment, recovering T cell generation and promoting thymus function repair and immune reconstruction aiming at thymus radiation injury. The placenta-derived endothelial progenitor cells are found to have an excellent effect of treating the radiation thymus injury, and the human placenta-derived endothelial progenitor cells and the human umbilical cord mesenchymal stem cells are synergistically combined to have a synergistic effect on treating the radiation thymus injury.

This invention provides exosomes derived from rice, their preparation method, and applications. The exosomes have a bilayered membrane spherical structure with a particle size ranging from 20 to 1000 nm. These exosomes are obtained from rice callus tissue and possess high biocompatibility, stability, and sustainable mass production characteristics. Furthermore, experiments have demonstrated that these exosomes have anti-aging, cell regeneration and tissue repair promotion, and protective functions, and can also significantly improve cell absorption efficiency and the delivery efficiency of active ingredients such as peptides.

The adjustable lumbar vertebra tractor comprises an armpit support and a limiting support piece which are connected up and down, a belt is installed on the limiting support piece, and an adjusting sleeve set is installed between the armpit support and the limiting support piece. A positioning mechanism is arranged among the armpit support, the limiting support piece and the adjusting sleeve set, and the positioning mechanism comprises a positioning boss and a positioning hole which are matched with each other; the adjusting sleeve set is composed of adjusting sleeves. The positioning holes are formed in the top of the adjusting sleeve and the top of the limiting supporting piece. The cervical vertebra rehabilitation device is suitable for being used in various occasions including working, has an adjusting function, generates traction force through self-pressing of the two armpits of the human body, enables vertebral joints to be relaxed, is free of pressure sense, achieves a bone mucosa self-repairing effect, promotes repairing and conditioning functions of synovial incarceration, and meanwhile has good conditioning and repairing functions on scapulohumeral spondylitis and scapulohumeral periarthritis.

The invention provides a blood-activating and toxin-expelling health-care gel and a preparation method thereof, and relates to the technical field of blood-activating medicines, the blood-activating and toxin-expelling health-care gel comprises a first substrate and a second substrate, the first substrate comprises the following components in parts by weight: 100-300 parts of caulis spatholobi, 100-300 parts of radix scrophulariae, 50-300 parts of honeysuckle, 50-300 parts of lycopodium clavatum, 50-300 parts of saffron and 25-150 parts of rhizoma smilacis glabrae. Traditional Chinese medicinal materials including caulis spatholobi, radix scrophulariae, honeysuckle and stigma croci in the first matrix have the effects of promoting blood circulation to remove blood stasis, clearing away heat and toxic materials and resisting inflammation, active ingredients in the traditional Chinese medicinal materials are effectively extracted through multiple times of decoction and concentration extraction, and it is ensured that the efficacy of the medicine is fully exerted. The water quantity control in the decoction process can ensure that all the components are completely dissolved out, and meanwhile, decoction solutions are combined after three times of decoction, so that the concentration of the extract is more uniform and stable.

The invention provides a lubricating-repairing bifunctional nano composite material as well as a preparation method and application thereof, and relates to the technical field of nano fillers. The invention provides a lubricating-repairing dual-function nano composite material. The lubricating-repairing dual-function nano composite material comprises a nitrogen-doped hierarchical pore carbon nanorod, a repairing agent and a lubricating agent, wherein the repairing agent is positioned in a pore channel of the nitrogen-doped hierarchical pore carbon nanorod, and the surface of the nitrogen-doped hierarchical pore carbon nanorod is coated with the lubricating agent. The nitrogen-doped hierarchical pore carbon nanorods are combined with the self-repairing agent and the lubricant, so that the nitrogen-doped hierarchical pore carbon nanorods have excellent friction-reducing, wear-resisting and repairing capabilities, can meet the application requirements in the fields of self-repairing and self-lubricating, and meet the requirements of high precision, high reliability and long service life of polymer-based self-lubricating materials under harsh working conditions; and the method has important significance for promoting the practical application of the polymer self-lubricating material in the modern high-end equipment industry.

The present invention discloses a terminal equipment maintenance method and system based on a domestic CPU and operating system, which belongs to the field of terminal equipment inspection and repair technology. The technical problem to be solved is how to perform security inspection and repair on a large number of terminals. The method includes the following steps: for the operating system of the terminal equipment to be inspected, a corresponding security inspection strategy is configured, the security inspection strategy includes all inspection items, security inspection details of each inspection item, and repair and reinforcement functions of each inspection item; security inspection is performed item by item on the terminal equipment locally based on the security inspection details, and the abnormal inspection items in the inspection results are prompted to the user; for abnormal inspection items, whether to perform repair and reinforcement is determined based on the user's choice; the abnormal inspection items that the user decides to perform repair and reinforcement are used as reinforcement items, and the repair and reinforcement functions corresponding to the reinforcement items are called to repair and reinforce the reinforcement items, and the execution results are prompted to the user.

The present invention relates to the use of a circular RNA molecule in the preparation of a drug for treating muscle injury, wherein the circular RNA molecule is circTXNIP, and its buffalo source sequence is shown in SEQ ID NO: 1. Overexpression of circTXNIP promotes the generation of circTXNIP-encoded peptides, thereby increasing the proliferation and differentiation of myoblasts; the circTXNIP forms a circTXNIP nucleic acid complex with liposomes as a component for preparing a drug for treating muscle injury. The circTXNIP-encoded peptide generated after the translation of the circTXNIP provided by the present invention can promote the repair of muscle injury, so circTXNIP is expected to be developed as a nucleic acid drug for the preparation of drugs for treating muscle injury, and can be used for treating muscle injury by local intramuscular injection.
