摘要： The present disclosure relates to the technical field of energy and power, in particular to an ejector with a core needle cooled by cooling medium. In the ejector with a core needle cooled by cooling medium, a cooling section is arranged between a stepping motor and a nozzle; the stepping motor, the cooling section and the nozzle are arranged coaxially, a partition plate and a sealing element are used to isolate the cooling medium from the primary flow medium, and the cooling medium is introduced into the cooling section to effectively cool the core needle therein, without affecting the adjustment function of the core needle for an area of the nozzle throat, so as to effectively improve the performance of the ejector. As the core needle is cooled, the adjustable ejector can be used in the primary flow fields with high temperature.

摘要： The present invention provides a class of novel NAMPT enzyme agonist and preparation and use thereof, which has a structural formula as shown in formula I or formula II. The present invention screens the NAMPT agonist NAT from the chemical small molecule library, and the NAT exhibits a good cytoprotective effect and a good anti-neurodegeneration effect in animal models of neurodegeneration. We studied the binding of NAT to enzymes, and then carried out multiple rounds of structure optimization based on the chemical structure characteristics of NAT and its enzyme activity properties, and obtained a relatively defined structure-activity relationship. The present patent not only lays the foundation for developing innovative drugs for anti-aging and neurodegenerative diseases, but also theoretically provides a proof-of-concept that enhancing NAMPT enzyme activity plays an important role in neuroprotection.
