The invention relates to the field of biological pharmacy, in particular to a pichia pastoris fermenting method for improving precursor expression of insulin and analogue thereof. The fermenting culture comprises the following stages of an initial growth phase, a glycerin supplementing phase and a methanol inducing phase. The method has the advantages that by controlling a formula of an initial culture medium, and the nitrogen source type and carbon source supplementing type, and continuously or semi-continuously supplementing a small amount of microorganisms or plant-source organic nitrogen sources in the middle and later period of fermenting, the fermenting cycle is extended; while the quality of the target product is guaranteed, the output is increased by not less than 30%.

The invention relates to a mixed suspension injection liquid containing tylosin and a preparation method thereof, belonging to the technical fields of veterinary antibiotic medicines as well aspreparation methods and an application thereof. The injection liquid comprises medicinal active ingredients, a suspending agent, a surface active agent, a flocculating agent, a pH regulating agent, water and auxiliary agents comprising an antiseptic agent and the like which are added when necessary. Water soluble raw material medicines are selected for the mixed suspension injection liquid containing tylosin, the medicines are separated out by a coacervation method, and the aqueous mixed suspension injection liquid with uniform particle distribution can be prepared. The method has the characteristics of simple and practicable process, no special equipment and lower cost. The dispersion medium of the obtained preparation is water, thus the problem of irritation induced by a conventional injection using an organic solvent is solved, and animal compliance is good. The prepared tylosin mixed suspension injection liquid forms a medicine store in vivo, exerts slow release and long-acting action and can be applied to a veterinary long-acting injection, which has good stability, good biocompatibility and absorption delay effect.

The invention relates to a decumbent corydalis tuber eye drop and a preparation method thereof. According to the decumbent corydalis tuber eye drop, the pH value is 4.6 to 6.5, and the permeation pressure is between 0.24 and 0.360 smol / kg; each 1,000 milliliters of decumbent corydalis tuber eye drop is prepared from the following substances: a decumbent corydalis tuber extract containing 0.32 to 0.43 gram of protopine, 0.0036 to 0.0048 mol of diluted phosphoric acid solution, and 0.1 to 3.0 grams of sodium dihydrogen phosphate, 3 to 8 grams of solubilizer, 0.2 to 0.8 gram of disodium edentate, 0.1 to 0.8 gram of bacteriostatic agent, 0 to 2.0 grams of thickening agent, 0 to 4 grams of medicinal ethanol solution of freshener, disodium hydrogen phosphate and glycerol which serve as auxiliary materials and the balance of water for injection, wherein the concentration of the diluted phosphoric acid solution is less than or equal to 0.5 mol / L, and a mass ratio of the freshener to medicinalethanol is 1:(1-15); the amount of the disodium hydrogen phosphate is used for regulating the pH value of the decumbent corydalis tuber eye drop; and the amount of the glycerol is used for regulatingthe permeation pressure of the decumbent corydalis tuber eye drop. The decumbent corydalis tuber eye drop has a mild effect, and the compliance of patients is improved greatly, so the decumbent corydalis tuber eye drop is an eye drop which is small in irritation and high in stability.

The invention relates to capparis spinosa fruit gel ointment, a production method thereof, and application thereof to antirheumatic medicaments. The capparis spinosa fruit gel ointment comprises a backing layer, a medicament-containing ointment body and a covering layer protective film, wherein the medicament-containing ointment body is prepared from the following raw materials: a medicinal part of the capparis spinosa and a medicinal excipient; a covering material of the covering layer protective film is one of release paper, a plastic film, a polyester, an aluminum foil-polyethylene composite film and hard gauze; and a backing material of the backing layer is one of cotton cloth, non-woven fabric and chemical fiber cloth. The apparis spinosa fruit gel ointment provided by the invention substitutes the apparis spinosa fruit serving as a medicament for the traditional root bark, so the contradiction between the resource utilization of the apparis spinosa medicinal plants and ecological protection is solved. More importantly, the apparis spinosa fruit gel ointment provided by the invention solves the problems of irritability and hypersensitivity caused by the clinical application of the traditional formulation and administration way of the apparis spinosa, and has the characteristics of long action time, high moisture retention, high air permeability, avoidance of the first pass effect of livers, using comfortableness and high compliance of patients.
