Abstract: A pharmaceutical composition contains tizoxanide and choline hydroxide, a choline salt of tizoxanide and crystal form thereof. A mixture of tizoxanide and choline hydroxide, or a salt thereof and crystal form of the salt significantly improve the solubility and bioavailability of tizoxanide, and exhibits favorable effects in drugs for treating viruses, fibrosis, bacteria, tumors and intestinal parasites.

Abstract: An entecavir monophosphate alaninamide phenolic ester derivative is represented by formula II. It has non-toxic pharmaceutically acceptable salts. In formula II, X is H, halogen, R or —OR, and R is a C1-3 alkyl or a substituted C1-3 alkyl. The entecavir monophosphate alaninamide phenolic ester derivative or the non-toxic pharmaceutically acceptable salt thereof can be used in the preparation of a drug for resisting the hepatitis B virus.

Abstract: A resveratrol derivative of the compound of formula I or a pharmaceutically acceptable salt thereof are effective for treating a fibrotic disease. In formula I, R1 is hydrogen or C1-C4 alkyl, R2 and R3 are each independently C1-C3 alkyl or C1-C3 deuterated alkyl, and R2 and R3 are the same or different; the C1-C4 alkyl or C1-C3 alkyl is optionally substituted with one or more substituents each independently selected from the group consisting of halogen (for example, fluorine, chlorine, bromine, iodine), methyl, hydroxyl, ethyl, amino, methoxy, and nitro; and R4 and R5 are substituted or unsubstituted C1-C3 alkyl. The fibrotic disease is selected from the group consisting of liver fibrosis, lung fibrosis, kidney fibrosis, and cardiac fibrosis.

Abstract: A passively balanced load-adaptive upper limb exoskeleton. An upper arm (A), an elbow (B), a forearm (C), and a hand (D) are arranged sequentially from left to right. An upper arm upper rod (A1) and an upper arm lower rod (A2) each are hinge-connected to an upper arm elbow housing via a bearing. A forearm upper rod (C1) and a forearm lower rod (C2) each are hinge-connected to a forearm elbow housing via a bearing. An upper arm support rod (E) is disposed between an upper arm driving mechanism (A4) and an upper arm elbow assembly (B1). One end of the upper arm support rod is fixedly connected to two upper arm support rod slide blocks (9) in the upper arm driving mechanism, and the other end thereof is hinge-connected to protruding shafts on two sides of an upper arm lead screw nut connection member via bearings. A forearm-upper arm support rod is disposed between a forearm driving mechanism (C4) and a forearm elbow assembly (B2).

Abstract: A method, apparatus and system for controlling a smart device based on a headphone are disclosed. The method includes: collecting, by the headphone, head motion feature data of a human body if a trigger condition of a collection task is satisfied; judging, according to the collected data, whether a target motion feature satisfying a predetermined motion feature is present in head motion feature of the human body; and if the target motion feature is present, acquiring information of an application currently running on the smart device, and generating an operation control instruction corresponding to the target motion feature according to the information of the currently running application and sending the operation control instruction to the smart device. According to the present application, control function may be enhanced for the smart device and control accuracy may be improved.

Abstract: A microwave frequency component includes a thin layer of dielectric material arranged between an earth electrode and a control electrode controlling a microwave frequency electrical signal such that the earth electrode extends over a first face, called the lower face, of the thin layer of dielectric material, and the control electrode extends longitudinally over a second face, called the upper face, of the thin layer of dielectric material. The microwave frequency component is such that it includes a set of at least two shielded coplanar electrodes extending along the entire length of the control electrode, to each side of and at an equal distance from the control electrode.
