Abstract: A treatment use of a pyrrolopyrimidine compound, and a solid pharmaceutical composition of a pyrrolopyrimidine compound. In particular, the present invention relates to a pyrrolopyrimidine compound or a pharmaceutical composition thereof for treating myeloproliferative neoplasms, and a method therefor or a use thereof.

Abstract: Provided are four crystal forms, A, B, C and D, of demethyleneberberine hydrochloride, and a preparation method therefor, and further provided are X-ray powder diffraction characteristic absorption peaks, infrared absorption peaks and DSC spectra of the four crystal forms. The X-ray powder diffraction characteristic diffraction peaks of the crystal forms are at about 8.205°, 8.805°, 10.817°, 14.835°, 15.479°, 16.668°, 17.492°, 18.529°, 20.656°, 21.536°, 23.538°, 25.657°, 26.192°, and 28.808°. A preparation method for the four crystal forms of the demethyleneberberine hydrochloride is also involved. The preparation method has a simple process, a high yield and a low cost; and has a high product purity and a stable quality.

Abstract: Embodiments of the present invention provide an antenna apparatus. The antenna apparatus includes multiple antennas, a switching unit, a grounding layer, connecting lines and a dielectric substrate. The antennas are configured to transmit and receive electromagnetic waves. The connecting lines are configured to connect the switching unit and the antennas. The switching unit is configured to selectively feed signals to the antennas through the connecting lines. The grounding layer serves as a reference of zero potential, and by setting the shape or size of the grounding layer and the distance from the grounding layer to the antennas, the grounding layer is further configured to restrain a transmitting direction of the electromagnetic waves transmitted by the antennas. The dielectric substrate is configured to allow the grounding layer to be printed thereon, and the dielectric substrate is further configured to allow the antennas, the switching unit and the connecting lines.
