Abstract: The present disclosure relates to a timbre selection method and apparatus, an electronic device, a readable storage medium, and a program product. According to the method, a timbre feature of a speech to be matched is obtained by analyzing a spectral feature of the speech to be matched, and then a target sample audio is determined from at least one sample audio based on a similarity between the timbre feature of the speech to be matched and a timbre feature of the at least one sample audio, where a timbre of the target sample audio matches the timbre of the speech to be matched.

Abstract: The present disclosure relates to the field of pet foods, and provides a composite nutritional freeze-dried snack containing a bacteriophage and a preparation method and a use thereof. The composite nutritional freeze-dried snack includes a nutritional mixture and an egg. A nutrition proportion provided by each plant extract in the composite nutritional freeze-dried snack provided by the present disclosure can achieve the effects of promoting growth of dogs and cats, resisting oxidation, strengthening immunity, resisting respiratory system infection, preventing pets from infection with pathogens and the like. Therefore, the composite nutritional freeze-dried snack has a good market prospect.

Abstract: Embodiments of the invention provides an information processing method and apparatus, a device, a medium and a product. The method comprises: determining a key frame in a target video corresponding to a player; obtaining target prompt information of a prompt object in the key frame; based on a playing area of the player, determining an information prompt area of the prompt object; and when the player plays the target video to the key frame, displaying the target prompt information in the information prompt area. Thus, the problem of a player only having one function is solved.

Abstract: The present invention relates to a strategy for combining a berberine analog with a JAK inhibitor in the treatment of inflammatory diseases of the gastrointestinal tract. Specifically, provided by the present invention is a pharmaceutical composition containing the berberine analog and the JAK inhibitor, and a use thereof in the treatment of inflammatory diseases of the gastrointestinal tract. The composition may exhibit an improved effect over the use of berberine or the JAK inhibitor alone.

Abstract: The present invention relates to a codrug that cleaved in the gut, preparation therefor, and a use thereof. Specifically, provided is a codrug compound in formula I. Also provided are a method of using the present compound for the treatment of gastrointestinal tract autoimmune diseases, inflammatory diseases, and cancers, as well as a method and an intermediate for preparing the present compound.
