The invention relates to a preparation method for a monosialotetrahexosyl ganglioside sodium injection. The method comprises the following steps of 1) weighing disodium hydrogen phosphate, sodium dihydrogen phosphate and sodium chloride, adding half amount of injection water, heating to a temperature of 40 DEG C to make the above material dissolved, and thus an auxiliary material solution is obtained; 2) weighing a raw material of monosialotetrahexosyl ganglioside sodium, adding into the above auxiliary material solution, and stirring until the is completely dissolved; 3) adding 20 g of activated carbon, stirring for 30 minutes, and filtering out the activated carbon; 4) supplementing the injection water until the volume of the injection water is 19 L, adjusting a pH value to 7.4-7.6 by using sodium hydroxide or hydrochloric acid, and supplementing the injection water until the volume of the injection water is 20 L; and 5) sterilizing for 20 minutes at the temperature of 121 DEG C by using rotary water bath sterilization after loading.

The invention belongs to the technical field of medicines, and particularly relates to a dantrolene sodium freeze-dried powder injection for injection and a preparation method thereof. The freeze-dried powder injection is prepared by freeze drying dantrolene sodium, lactobiose, a pH regulator and water for injection, wherein a mass ratio of the dantrolene sodium to the lactobiose is (1:0.5) to (1:2.5). The preparation method comprises the following steps of: adding the dantrolene sodium to the lactobiose in a prescription amount into the water for the injection, stirring, regulating the pH value to 9.0 to 10.5 by using the pH regulator, adding active carbon for injection, removing a heat source, decolorizing, filtering for decarburizing, performing fine filtering by using a filter membrane, packaging in separate bags, freezing and drying. The dantrolene sodium freeze-dried powder injection is studied on the basis of a freeze-dried process, namely the dantrolene sodium freeze-dried powder injection is cooled, heated by a small margin and is cooled again, so that the moisture of the freeze-dried product is reduced, and the freeze-dried product is high in redissolution and visible foreign matters and does not have insoluble granules. The dantrolene sodium freeze-dried powder injection for the injection is high in resolubility, clarity and stability, and low impurity content.

The invention relates to an acyclovir lyophilized formulation for injection and a preparation method of the acyclovir lyophilized formulation. The acyclovir lyophilized formulation for injection comprises acyclovir, sodium hydroxide, mannitol and a pH value stabilizing agent, wherein the weight ratio of the acyclovir to the mannitol is 1;(1-10). The acyclovir lyophilized formulation is advanced in prescription and good in product formability; the solution before being frozen is clear in appearance; the lyophilized product is good in solubility; and the re-dissolved solution is good in clarity, low in impurity content, good in stability and controllable in quality.

The invention relates to a novel method for preparing small-particle-size high-encapsulation-efficiency lipidosome coated with protein drugs and belongs to the technical field of biological medicines. The preparation process comprises the following steps: a, dissolving lipids for forming the lipidosome in an organic solvent, mixing the lipids, a protein solution and a proper amount of surfactant according to a proper ratio, and preparing a micro-emulsion phase; b, dissolving the lipids for forming the lipidosome in an organic solvent, mixing and hydrating by using water or a buffer solution or alcohol according to a proper ratio, and preparing a micellar phase; and c, mixing the micro-emulsion phase and the micellar phase, reversing the phase b into a reverse micelle, reversing the phase b again in the process of removing the organic solvent under reduced pressure, finally covering the surface of the phase a micelle with the reverse micelle, and forming the lipidosome. The encapsulated protein drug lipidosome has the average particle size of about 80nm, and the encapsulation ratio can be over 90 percent. The preparation process is simple in process, the production cost is reduced, and industrial production is easily realized.

The invention provides a solution agent for recombining human interleukin 12 and a preparation method thereof. The solution agent comprises the human interleukin 12, a phosphate buffer (PB), NaCl and poloxamer 188, wherein pH of the solution agent is maintained to range from 6.0 to 7.2 through the phosphate buffer. The solution agent is good in stability, clear in appearance and free of insoluble substances, preservative and blood components, and the in-vitro activity of contained active polypeptide is stable; under specified conditions, the solution agent can be stably preserved for at least eight months, and compared with a powder injection, the production quality is obviously improved.

The invention, which relates to the technical field of beverage processing, provides a preparation method of pitaya juice. The preparation method of the pitaya juice comprises the following steps: (1), carrying out pitaya pretreatment; (2), carrying out peel treatment; (3) carrying out pulp treatment; (4), carrying out juice blending; (5), carrying out juice treatment; and (6), carrying out filling and sterilization. The pectin and haematochrome in peels are extracted as additives to prepare pitaya juice, so that waste is turned into wealth and the comprehensive utilization rate of pitaya is greatly increased; and the prepared pitaya juice is clear and bright in color and luster, refreshing and fine in taste, uniform and stable in juice state and harmonious and rich in aroma.

The invention provides a dextrooracetam freeze-dried powder injection with good stability; the dextrooracetam freeze-dried powder injection is prepared by freeze-drying a solution prepared from crystalline-form dextrooracetam, a freeze-dried excipient, a metal ion chelating agent, a pH regulator and water for injection.
