Abstract: Disclosed are a polyethylene glycol conjugate drug, and a preparation method therefor and the use thereof. Specifically, the present invention relates to a polyethylene glycol conjugate drug represented by formula A or a pharmaceutically acceptable salt thereof, a method for preparing the polyethylene glycol conjugate drug or the pharmaceutically acceptable salt thereof, an intermediate for preparing the polyethylene glycol conjugate drug or the pharmaceutically acceptable salt thereof, a pharmaceutical composition comprising the polyethylene glycol conjugate drug or the pharmaceutically acceptable salt thereof, and the use of the polyethylene glycol conjugate drug or the pharmaceutically acceptable salt thereof in the preparation of a drug.

Abstract: Provided is a curved liquid crystal display panel, including a color film substrate and an array substrate. An orthographic projection of the color film substrate on the array substrate is within the array substrate. The color film substrate includes a first side surface and a second side surface. The array substrate includes a third side surface and a fourth side surface. The first side surface is adjacent to and staggered from the third side surface. The second side surface is adjacent to and staggered from the fourth side surface. At positions where the third side surface and the fourth side surface are disposed, each of a side, proximal to the color film substrate, of the array substrate and a side, distal from the color film substrate, of the array substrate includes a structure formed by a grinding process.

Abstract: A quasi-axial optical imagery projection system is disclosed in this paper. The system includes optical imagery sets; each may be lenses, mirrors, or a combination of both. The system also has a light source close to an imager, which may be a planar mask with a pattern, a LCD imager, or other suitable imagers. The system also has a display screen. Both the imager and the display screen are set at acute angles with respect to an optical axis so that what is projected on the display screen is a magnified image of the imager by a magnification factor that has a transverse component and a longitudinal component. This quasi-axial projection system may be made thinner than other rear projection system of comparable screen size.
