The utility model discloses a steel billet slag scraping structure of a continuous casting machine, which belongs to the technical field of metallurgical equipment and comprises a terminal roller way, a steel pusher, a water spraying unit and a scraping unit. The steel pushing machine is arranged between rollers of a terminal roller way and pushes the steel billet limited by the collision plate to move in the axial direction of the rollers; the water spraying unit and the scraping unit are sequentially arranged on the line along which steel is driven by a steel pusher to move, the water spraying unit is provided with a spray head for spraying water to the front end face of a steel billet, and the scraping unit is provided with a steel brush for scraping the front end face of the steel billet. The device is compact in structure, rapid cooling and efficient slag scraping treatment of the end face of a steel billet can be achieved, the adhesive force and definition of spray marks are remarkably improved, and the problem of furnace number confusion caused by spray mark falling is solved. The device is high in automation degree and stable in operation, can be seamlessly integrated with an existing continuous casting production line, and has good practicability and popularization value.

This utility model belongs to the field of valve technology, specifically disclosing a conical flow-guiding anti-clogging electric regulating valve for thermal pipeline networks. The utility model includes a valve body with a connecting seat on one side. Filter components are located on both sides of the valve body, and a flow regulating component is located on one side of the connecting seat. The filter components achieve staged filtration through two filter screens with different mesh sizes. The larger mesh screen first intercepts large impurities, preventing them from impacting and scratching subsequent components, while the smaller mesh screen filters out finer impurities, achieving comprehensive removal of impurities from the medium. Combined with the conical flow channel's characteristic of reducing impurity retention, this significantly reduces the risk of valve clogging. Furthermore, the filter screens can be installed and removed without tools, ensuring stable operation under medium impact, continuously guaranteeing the efficient and safe operation of the valve and thermal pipeline network, and extending equipment lifespan.

The invention belongs to the technical field of biological medicines, and particularly relates to vitexin-probucol self-assembled nanoparticles as well as a preparation method and application thereof. The nanoparticle is formed by self-assembly of vitexin and probucol, and the mass ratio of vitexin to probucol is 2: (1-5). The nano particles are prepared by adopting a nano precipitation method, and the method specifically comprises the following steps: mixing vitexin and probucol, and dissolving and dispersing in a good solvent to obtain a mixed solution; and adding the obtained mixed solution into a poor solvent, and promoting the vitexin and probucol to be self-assembled to form the nanoparticles by utilizing a solvent replacement effect. The nanoparticles have the advantages of high drug loading capacity, synergistic anti-inflammation and anti-oxidation, long-acting circulation and the like, and can effectively treat atherosclerosis, reduce side effects and improve the treatment effect and safety.

The present application relates to the technical field of biological medicine, in particular to a mesenchymal stem cell exosome composition for repairing wound and a preparation method thereof.The preparation raw material of the exosome composition comprises the following components in parts by weight: mesenchymal stem cell exosome 0.15-0.2 parts, modified hyaluronic acid 3-5 parts, modified dandelion extract 5-8 parts, and carboxymethyl chitosan 2-3 parts.The exosome composition prepared by the present application can effectively promote wound repair.

The application provides an exosome composition for reducing side effects of chemotherapy treatment and a preparation method thereof, and belongs to the technical field of medicines. Methotrexate, vinblastine and daunorubicin are prepared into a co-crystal, loaded on UiO-66-NH2 connected with RGD, loaded on exosomes, and embedded in an acrylic acid, traditional Chinese medicine polysaccharide and pullulan compound to obtain a sustained-release high half-life exosome system, which is uniformly mixed with D-ribose, yeast-beta glucan and glutathione to obtain the exosome composition for reducing side effects of chemotherapy treatment. The traditional Chinese medicine polysaccharide is traditional Chinese medicine polysaccharide obtained by boiling water extraction and ethanol precipitation of radix codonopsis, angelica, polygonatum sibiricum and dendrobium officinale. The exosome composition for reducing side effects of chemotherapy treatment is prepared, drug resistance of tumor cells is reduced, drug efficacy is improved, side reactions after chemotherapy are reduced, the effect of targeted slow release of drugs is achieved, and the exosome composition has a wide application prospect.
