  • Publication number: 20220090914
    Abstract: A light projection method with safety protection and a light projection device with safety projection. The light projection method (200) comprises: turning on a light source at a safe power level (S201); using a diffractive optical element to modulate light emitted from the light source so as to project a pattern onto a target surface (S202); acquiring the pattern (S203); determining whether the pattern is normal (S204); and if so, turning on the light source at a rated power level, wherein the rated power level is higher than the safe power level (S205). The invention enables an optical system to have a smaller size while ensuring safety of a user, simplifies a structure, reduces costs, and facilitates efficient utilization of optical energy.

  • Patent number: 11110139
    Abstract: The disclosure provides an application of an anthocyanin extract in preparing a pharmaceutical composition for preventing and treating cardiac toxicity induced by Anthracyclines and the pharmaceutical composition, wherein the pharmaceutical composition comprises an effective dose of the anthocyanin extract; and the anthocyanin extract refers to an extract obtained from mature fruits of a zygophyllaceous nitraria plant and having a total anthocyanin content greater than 700 mg CGE/g and a total antioxidant capacity greater than 200 mg TE/g. Cytobiology and molecular biology studies prove that the anthocyanin extract has obvious protection effect to cardiomyocyte toxicity damage induced by anthracyclines and may be used for preventing and alleviating cardiotoxicity of an antharcyclines anticancer drug, thereby expanding a clinical application of the antharcyclines anticancer drug and relieving toxic and side effects brought by the antharcyclines anticancer drug to a patient and pain of a chemotherapy patient.

  • Patent number: 10699100
    Abstract: A method for microscopic image acquisition based on a sequential slice. The method includes; acquiring a sample of the sequential slice and a navigation image thereof; identifying and labeling the sample of the sequential slice in the navigation image by utilizing methods of image processing and machine learning; placing the sample of the sequential slice in a microscope, establishing a coordinate transformation matrix for a navigation image-microscope actual sampling space coordinate, and navigating and locating a random pixel point in the navigation image to a center of the microscope's visual field; locating the sample of the sequential slice under a low resolution visual field, binding a sample acquisition parameter; based on the binding of the sample acquisition parameter, recording a relationship of relative of locations between a center point of a high resolution acquisition region and a center point after being matched with a sample template.
