The present disclosure is directed to a method of producing human gastric insulin-secreting (GINS) cells and human gastric insulin-secreting (GINS) organoids. The present disclosure provides a population of human gastric insulin-secreting (GINS) cells and a preparation of human gastric insulin-secreting (GINS) organoids, which are glucose-responsive and insulin-secreting. The present disclosure also provides methods of controlling glycemia in a human subject by transplanting to the human subject the population of human GINS cells or the preparation of human GINS organoids.

The utility model relates to a model for simulating dynamic gastric peristalsis. The model comprises a supporting bottom plate; a first roller is arranged on the first driving assembly; a second roller is arranged on the second driving assembly; the stomach support is located between the first driving assembly and the second driving assembly, and a stomach model is arranged on the stomach support; wherein the structures of the first roller and the second roller are the same, the first roller and the second roller are cylinders, the sections of the cylinders of the first roller and the second roller are triangular, the first driving assembly drives the first roller, and the second driving assembly drives the second roller to synchronously contact with the stomach model and extrude the stomach model to simulate gastric peristalsis. According to the model capable of simulating dynamic gastric peristalsis, the roller structure of the cylinder with the triangular section is more suitable for analog simulation of the gastric peristalsis part of dynamic human gastrointestinal digestion equipment, when the chamfer of the triangular roller is in contact with the stomach model, the extrusion depth is deeper, the force for pushing chyme in the stomach is larger, and the chyme can be better discharged.

The invention discloses a gastric antrum peristalsis image processing method and system based on a double-lens gastroscope capsule. The method comprises the following steps: acquiring a gastric antrum video sequence shot by the double-lens gastroscope capsule in the stomach of a human body; the double lenses are a first lens and a second lens which are arranged at two axial ends of the gastroscope capsule and are used for respectively acquiring images of a forward view angle and a backward view angle of the capsule; performing motion information processing on the video sequences from the first shot and the second shot to obtain motion features representing gastric wall deformation or image displacement; based on the motion features of the first lens and the second lens, consistency analysis is carried out on the motion directions, change trends and periodic features of the first lens and the second lens in the same time period, and when the motion features of the two lenses meet a preset consistency condition, it is judged that a gastric antrum wriggle event exists in the corresponding time period; and judging time sequence integrity and outputting a result. The accuracy and stability of gastric antrum peristalsis image recognition are improved.
