The present invention relates to the technical field of medicine, and relates to efonidipine hydrochloride solid powder and a preparation method thereof, wherein an insoluble drug efonidipine hydrochloride crystal is subjected to nanocrystallization or micronization through a media grinding method so as to improve the in vitro dissolution characteristic of the efonidipine hydrochloride. According to the present invention, the efonidipine hydrochloride solid powder comprises the drug and a diluent, wherein the diluent is one or a plurality of materials selected from microcrystalline cellulose, calcium hydrogen phosphate, PVPP-XL-10 and an enteric material, preferably PH101 microcrystalline cellulose and EudragitL100-55, the drug accounts for 12.5-50% of the weight of the solid powder, preferably 16.7-25%, and the ratio of the drug to the diluent is 1:1-1:5. The solid powder of the present invention provides a good intermediate for preparation of the efonidipine hydrochloride capsules or ...

The invention discloses plant light energy conversion efficiency correlated protein and encoding gene and application thereof. The protein provided by the invention is the protein (a) or (b) as follows: (a) protein with an amino acid sequence shown as the sequence 1 in a sequence table; or (b) protein which is derived from the sequence 1 by substituting and/or deleting and/or adding one or more amino acid residues on the amino acid sequence as the sequence 1, and is associated with the plant light energy conversion efficiency. The invention provides a method for culturing a transgenic plant, i.e. the encoding gene of the protein is transferred into a target plant to acquire a transgenic plant of which the growing ability and/or light energy conversion efficiency is higher than that of the target plant. The invention provides a genetic material and foundation for researching and acquiring a new species of high photosynthetic resistant and strong stress crop.
