The invention relates to a glutamic acid-N-carboxyl-anhydride monomer containing an ethyl nitrate group, a polymer of the glutamic acid-N-carboxyl-anhydride monomer containing the ethyl nitrate group, and an application of the glutamic acid-N-carboxyl-anhydride monomer containing the ethyl nitrate group and the polymer of the glutamic acid-N-carboxyl-anhydride monomer containing the ethyl nitrate group as a nitric oxide donor. The polyethylene glycol block-containing copolymer can be independently polymerized or copolymerized with other amino acid-N-carboxyl-anhydride monomers to form an NO donor polymer, and the polyethylene glycol block-containing copolymer can form a nano structure through self-assembly so as to efficiently load a hydrophobic drug. The drug can be accurately delivered to tumor tissues or cardiovascular and cerebrovascular disease parts in a targeted manner, and the controllable release of NO and / or loaded drugs is realized, so that the effect of inhibiting tumors and cardiovascular and cerebrovascular diseases is achieved. Structural formula of glutamic acid-N-carboxyl-intracyclic anhydride monomer containing ethyl nitrate group is as shown in formula (I): # imgabs0 #

The invention discloses a solid particle of double-membrane nitric acid 2-(4-methylthiazol-5-yl) ethyl ester hydrochloride and a solid pharmaceutical preparation prepared from the solid particle. The solid particle is a drug-containing particle sequentially coated with an oily membrane and a high polymer material membrane. According to the invention, a double-membrane strategy is adopted, and the problems of content reduction and easy degradation caused by sublimation of a main drug are effectively solved through a membrane protection barrier formed by a fat-soluble material and a high polymer material.

The invention discloses a nanotechnology diesel oil modifier, a preparation method and application thereof and clean environment-friendly diesel oil containing the nanotechnology diesel oil modifier. The nanotechnology diesel oil modifier is prepared from the following components in parts by volume: 10 to 30 parts of white oil, 10 to 40 parts of diesel oil purification synergist, 40 to 85 parts of ethyl nitrate and 20 to 50 parts of dimethyl carbonate. The diesel purification synergist comprises a stock solution and a diluted solution, the stock solution is prepared from isomeric alcohol ethoxylates, triphenyl phosphate, 2, 6-di-tert-butyl-4-methylphenol, polyisobutylene succinic anhydride and dodecyl methacrylate according to the volume part ratio of (25 to 40) to (10 to 20) to (10 to 20) to (15 to 30) to (20 to 35); the diluted liquid is an oligomeric water cluster; the stock solution accounts for 0.5%-2% of the diesel cleaning synergist in percentage by weight. The nanotechnology diesel oil modifier is a pure petroleum product, can change the physical properties of diesel oil after being added into the diesel oil, achieves the effects of improving efficiency, saving oil, cleaning carbon and reducing emission, and is suitable for popularization and application.
