The invention discloses a method for preparing lobster sarcosinine by using nereis as a raw material, and the lobster sarcosinine is prepared by adopting a combined process of reverse phase silica gel column chromatography, gel column chromatography, normal phase silica gel column chromatography and HPLC (High Performance Liquid Chromatography) preparation. Compared with a traditional lobster extraction method for preparing lobster sarcosinine, the method provided by the invention can realize high-purity separation of a target product; and the methanol solvent used in the process can be recycled through distillation, thereby conforming to the concept of green production. Therefore, deep development and efficient utilization of marine resources can be promoted, natural marine drug resource reserve is enriched, a new direction is provided for research and application in the fields of healthy development of human beings and disease prevention and control, and remarkable social benefits are achieved.

The utility model relates to medical technology field discloses a kind of plaster components, plaster component includes: plaster paste, including sticking layer, medicine package and heating bag, sticking layer one side is provided with first viscose layer, medicine package is bonded to the side for contacting with skin of first viscose layer, heating bag is fixedly connected with sticking layer, heating bag is filled with spontaneous heating material that contact with air and generate heat;Packaging bag, it is wrapped in the outside of plaster paste, to isolate heating bag and air.The plaster component provided by the utility model is set to heating bag, to facilitate the local temperature of skin to be increased by heat effect, be favorable to make skin pore open, enhance local blood circulation, and then make external medicine better be absorbed by skin and be used, reduce drug resource waste;And by setting packaging bag isolation heating bag and air, to prevent when not using plaster paste, spontaneous heating material in heating bag and air reaction heat generation.

The utility model relates to the technical field of environmental pollution abatement equipment, in particular to a buoy chemical feeding device for environmental pollution abatement, which comprises a buoy body, a chemical supply unit and an aeration pump, the chemical supply unit is specifically a ton barrel, the upper end of the ton barrel is provided with a chemical feeding port and a water injection port, the ton barrel is sequentially arranged on the buoy body at intervals in the length direction of the buoy body, and the ton barrel is used for storing chemicals and releasing the chemicals to a river channel; the three ton buckets are arranged on the buoy body at equal intervals and matched with the liquid discharging pipes, the flow adjusting pumps, the metering pumps and other components, medicine of all the ton buckets can be gathered through the independent liquid discharging pipes and then released into a river channel through the PVC pipes which are horizontally laid and provided with the multiple sets of discharging openings, and through the design, the medicine can be evenly distributed in the width direction of the river channel; the problem that the local drug concentration is too high or too low is effectively avoided, drug resources are fully utilized, and the sewage treatment efficiency is remarkably improved.

Systems, methods, and apparatuses are described herein for determining a drug shortage in an electronic environment. The present invention is configured to identify at least one drug identifier; identify at least one route type for the at least one drug resource identifier; determine at least one feature type associated with the at least one drug identifier, wherein each feature type comprises at least one attribute; generate a shortage score for the drug identifier; apply a post-score change to the shortage score, wherein the post-score change is based on at least one supplemental feature; and generate a drug shortage score based on the post-score change applied to the shortage score.
