The invention relates to a tetramethylpyrazine phosphate liposome drug and a preparation method; wherein, the drug is characterized in that: the effective efficacy components and weight accounts of the liposome drug are as following: a mixture 200 to330 with a weight ratio 4 to 1 of egg yolk lecithin and sheep cerebral lecithin, a mixture 170 to 280 with a weight ratio 3 to 1of stigmasterol and campestrol, reduction glutathione 2.5 to 10, tetramethylpyrazine phosphate 15 to 25, a mixture 720 to 1200 with a weight ratio 1 : 0.01 to 0.05 : 0.02 to 0.07 of tert-butyl alcohol, ethanol, acetone, amixture 140 to 160 with a weight ratio 4:05 to 1 of polyethylene glycol-2000 and tween 801, and hydroxyl propyl methyl cellulose 100 to 120. The invention also provides the preparation method for theliposome drugs. The invention has the advantages of adopting the provided drugs, enabling to decrease the drug dosage by two third and once a day, and improving the efficacy above fifteen percent.

The invention discloses a multi-gradient drug-loading microsphere having magnetic response and prepared through dual in-situ hybridization. According to the dual in-situ hybridization principle and the nano self-assembly technology, a bone repair drug-loading microsphere is developed; chitosan serves as an organic matrix, ferric chloride and ferrite serve as precursors of inorganic phase Fe3O4, and a calcium-microcosmic salt solution serves as a precursor of inorganic phase hydroxyapatite; a chitosan solution containing traditional Chinese medicine and icariin is fully and evenly mixed with the ferric chloride and the ferrite firstly, and then is evenly and fully mixed with soluble calcium salt, by means of a high-voltage static microsphere forming device, the mixture is dipped into an alkali liquor containing soluble phosphate drop by drop, the mode that organic macromolecules are adopted in biomineralization to control inorganic phase growth is simulated, the organic macromolecules become nuclear crystals on the organic matrix in a dual in-situ hybridization mode, and the multi-gradient drug-loading microsphere is prepared. The novel bone repair material is simple in preparation process, biocompatibility is good, and the capacity of controlling slow release of medicine is obviously enhanced through unique biological magnetic guide quality and multi-gradient performance.

The invention provides a method for preparing disodium hydrogen phosphate by taking phosphoric acid and sodium sulfate as raw materials. According to the mol ratio of1:1.6-2.4 , the phosphoric acid and the sodium sulfate are mixed and stirred and added with ammonia water with mass percentage of between 26 and 28 percent or liquid ammonia; the pH value of the system is adjusted to more than 8.0; the raw materials are subjected to cool crystallization at a temperature of between 15 and 25 DEG C, and filtered to obtain a dibastic sodium phosphate crystal and a filtrate; the dibastic sodium phosphate crystal is added with soda ash and evenly mixed, wherein the soda ash is added according to the mol ratio of Na: P element of 2, the dibastic sodium phosphate crystal and the soda ash react at a temperature of between 180 and 250 DEG C for one hour to obtain the disodium hydrogen phosphate; and the filtrate is subjected to condensation and crystallization to obtain ammonia sulfate. The methodhas the characteristics of saving cost and recycling the generated ammonia gas, and the disodium hydrogen phosphate product prepared by the method meets the requirements of the HG / T2965-2000 industrial disodium hydrogen phosphate index.
