Abstract: Provided are a crystal form of a multi-substituted benzene ring compound maleate, and a preparation method therefor and the use thereof. The crystal form of the multi-substituted benzene ring compound salt represented by formula II has good physicochemical stability, high solubility, less hygroscopicity, good flowability and more preparation process options, and is more suitable for industrial production, which is of great value for drug optimization and development.

Abstract: The present invention relates to an antibody and an antibody-drug conjugate, and particularly to an antibody and an antibody-drug conjugate (ADC) targeting the tissue factor, and a composition comprising the antibody or ADC, and a therapeutic application thereof.

Abstract: An antibody and an antibody-drug conjugate, which relate to an antibody and an antibody-drug conjugate (ADC) targeting Claudin 18.2 (CLDN18.2), as well as compositions containing the antibody and ADC molecules, and a therapeutic application thereof.

Abstract: Provided is a monocyclic ?-lactam compound as shown in general formula (I), or an ester, a stereoisomer or a pharmaceutically acceptable salt thereof. Also provided are a pharmaceutical composition containing the monocyclic ?-lactam compound as shown in general formula (I), or an ester, a stereoisomer or a pharmaceutically acceptable salt thereof, and the use thereof in the preparation of a drug for treating bacterial infections.

Abstract: Disclosed is a double-sided color photographic paper, including, in order, a first protection layer, a first photosensitive layer, a supporting substrate, a second photosensitive layer and a second protection layer. The supporting substrate has a first surface and a second surface opposite to the first surface. A first barrier layer and at least one layer of a first shading layer are sandwiched between the first photosensitive layer and the first surface of the supporting substrate. The first barrier layer is arranged between the first photosensitive layer and the first shading layer; a second barrier layer and at least one layer of a second shading layer are sandwiched between the second surface of the supporting substrate and the second photosensitive layer, and the second barrier layer is arranged between the second shading layer and the second photosensitive layer.
