Abstract: A photographing method in a long-focus scenario and a terminal are provided. A moving direction and a moving distance of a framing range of the terminal can be controlled, so that a target photographing object accurately moves into the framing range, to improve efficiency of interaction between a user and the terminal. The method provides, when a zoom magnification used by a terminal is greater than or equal to a preset magnification, a photographing interface displayed by the terminal includes a first viewfinder frame and a second viewfinder frame. The first viewfinder frame is used to preview an image captured by a long-focus camera. A framing range of the second viewfinder frame is greater than a framing range of the first viewfinder frame, and a framing range the same as that of the first viewfinder frame is marked in the second viewfinder frame.

Abstract: Disclosed herein are pharmaceutical compositions comprising carboxyalkylcellulose esters for sustained delivery of pharmaceutically active substances. The composition comprises: at least one pharmaceutically active agent, and at least one carboxyalkyl cellulose ester comprising an anhydroglucose repeat unit having the structure: wherein: R1-R6 are each independently selected from —OH, —OC(O)(alkyl), and —O(CH2)xC(O)OH, and pharmaceutically acceptable salts thereof, wherein x ranges from 1-3, a degree of substitution per anhydroglucose of —OH ranges from 0.1 to 0.7, a degree of substitution per anhydroglucose of —C(O)(alkyl) ranges from 0.1 to 2.7, and a degree of substitution per anhydroglucose of —O(CH2)xC(O)OH ranges from 0.2 to 0.75, and wherein in pharmaceutically acceptable media, the composition exhibits sustained release of the at least one pharmaceutically active agent.

Abstract: Pharmaceutical preparations and methods that contain enteric polymers formulated in liquid dosage forms. The preparations and methods provide enteric properties of delayed and then sustained release, without the need for expensive tableting or coating processes.

Abstract: A solid composition suitable for forming into a tablet includes a pharmaceutically active substance in an amount sufficient to provide a therapeutic effect when administered; from about 0.2 to about 15 weight %, based on the total weight of the composition, of a water-soluble preparation of a fat-soluble vitamin; and from about 10 to 80 weight %, based on the total weight of the composition, of an excipient. Another aspect of the present invention is method for making the solid composition.

Abstract: A novel process for preparing polymers having an average particle size of less than about 40 micrometers is described. The process involves dissolving a polymer in a solvent to form a solution that is introduced into an agitating aqueous medium.
