Abstract: A heart valve prosthesis device includes a stent and leaflets. The stent includes an annular part and guide parts. A first end of the annular part includes cell sections arranged in sequence in a circumferential direction of the annular part. The guide parts are arranged at intervals in the circumferential direction of the annular part, one side of each guide part is connected to a corresponding cell section, and the other side gradually tapers to an end where a retrieval cell is provided for a pulling wire to pass through. Each guide part includes a first region being the retrieval cell, a second region aligned with the first region and configured as a central region, and a third region and a fourth region distributed on two sides of the central region in the circumferential direction of the annular part.

Abstract: Embodiments of the present disclosure provide a method and apparatus for generating information, and relate to the field of cloud computation. The method may include: receiving a video and an audio of a user from a client; analyzing the video and the audio to determine an intention category of the user; generating feedback information according to the intention category of the user and a preset service information set; generating a video of a pre-established three-dimensional virtual portrait by means of an animation engine based on the feedback information; and transmitting the video of the three-dimensional virtual portrait to the client, for the client to present to the user.
