This invention relates to a microarray needle-like liquid capsule, its preparation, and its application, belonging to the field of biomedical materials technology. The microarray needle-like liquid capsule is composed of soluble microneedles and an encapsulating agent, possessing a hollow structure capable of loading chemotherapeutic drugs, particularly suitable for non-water-soluble drugs. This design effectively solves the problem of insufficient drug loading capacity in traditional microneedles and improves drug bioavailability by using ethanol as a solvent, while simultaneously achieving synergistic treatment of chemotherapy and local tumor ablation. This invention not only possesses excellent mechanical properties and biocompatibility but also demonstrates significant advantages in the treatment of melanoma, reducing skin inflammation and improving patient comfort.

This invention discloses a data annotation method, apparatus, storage medium, and program product, relating to the field of artificial intelligence. The method includes: inputting a target sample into a target language model to obtain N candidate labels, wherein the target sample includes data samples to be labeled; calculating the similarity between each candidate label and S standard labels to obtain N similarity sets, wherein each similarity set includes the similarity between one candidate label and the S standard labels, and the standard labels include labels defined based on domain knowledge and business requirements of the target sample's domain; and determining the target label for the target sample from the S standard labels based on the N similarity sets. This invention solves the technical problem in related technologies where labels directly annotated by models are difficult to utilize directly, leading to low utilization rates of sample labels.
