The invention provides a controlled release oral solid formulation comprising (a) a controlled release component comprising core comprising levodopa and / or an ester of levodopa or salts thereof, wherein the core is coated with a layer of a muco-adhesive polymer and externally coated with a layer of an enteric coated polymer; and (b) a decarboxylase inhibitor component.

Use the general formula CH 3 (CH 2 ) x CH 2 (OCH 2 CH 2 ) n Polyglycol ethers of alkyl alcohols of OH, wherein x is 8-20 (wherein ceteareth-20, stearyl ether-20 and stearyl ether-100 are preferred), poloxamer 185, Poloxamer 407, N, N-dimethyldodecylamine N-oxide and mixtures thereof to improve the hair follicle transport and / or hair follicle residence time of certain water-soluble ornithine decarboxylase inhibitors, preferred inhibitors are 2-(difluoromethyl)-2,5-diaminovaleric acid and its pharmaceutically acceptable salts, hydrates, optical enantiomers and racemic mixtures.

Disclosed are inhibitors of mevalonate pathway as an efficient vaccine adjuvant and use thereof. In particular, the inhibitor is an acetoacetyl-CoA transferase inhibitor, a HMG-CoA synthase inhibitor, a HMG-CoA reductase inhibitor, a mevalonate kinase inhibitor, a phosphomevalonate kinase inhibitor, a mevalonate-5-pyrophosphate decarboxylase inhibitor, an isopentenyl pyrophosphate isomerase inhibitor, a farnesyl pyrophosphate synthase inhibitor, a geranylgeranyl pyrophosphate synthase inhibitor or a geranylgeranyl transferase (I, II) inhibitor. Also disclosed is an immunogenic composition comprising inhibitors of mevalonate pathway as an adjuvant.

The invention provides a polygala tenuifolia extract for a parkinson's disease and a preparation method and an application of the polygala tenuifolia extract. The method comprises the following specific steps: taking a polygala tenuifolia material, adding 95% ethanol to soak over the night, carrying out heating reflux extraction and filtration and recovering ethanol until no alcohol taste in a vacuum condition to obtain an alcohol extract; adding water to soak the residual filter residues after filtration over the night, carrying out heating reflux extraction, filtration and vacuum concentration until a liquid extract to obtain a water extract; mixing the alcohol extract and the water extract at equal volume; adding petroleum ether, carrying out extracting and separating to remove the petroleum ether part; adding chloroform to the residual water solution, extracting and collecting a chloroform extracting solution; and concentrating the chloroform extracting solution until an extract, drying the extract in vacuum and crushing the product to obtain the effective part B. Through an in vitro anthropogenic dopa decarboxylase inhibitor screening model, the screened polygala tenuifolia effective part B has obvious anti-PD activity and can be applied to preparation of anti-PD medicines.
