Abstract: The present invention provides a train-like pharmaceutical composition (configuration, or dosage form) comprising segments linearly arranged in series like cars of a train. When the pharmaceutical composition is administrated into a patient's body, some of the segments are “visible” to an instrument, but others are not. However, “invisible” segments can be estimated, deduced, calculated, or inferred from “visible” segments. The “invisible” segments can be used for neutralizing intratumoral lactic acidosis combined with glucose deprivation to control tumor, among other applications.

Abstract: This application relates to the field of image processing, and provides a point light source image detection method and an electronic device. The method includes: obtaining to-be-tested images, and determining pixel brightnesses of the to-be-tested images; determining low-brightness pixels and high-brightness pixels in the images based on the pixel brightnesses; filtering, based on the low-brightness pixels, out an image that does not meet a preset dark environment requirement, and filtering, based on the high-brightness pixels, out an image that does not meet a preset point light source size; and determining, based on a result of the filtering, whether a to-be-tested image is a point light source image. Pixels in images are classified into low-brightness pixels and high-brightness pixels. For the low-brightness pixels, the images are screened based on a preset dark environment requirement, so that the selected point light source images meet the preset dark environment requirement.
