The staining bath may include a nonionic surfactant. The method is carried out in the absence of chromium salts. Also disclosed are (i) a dyed suture material produced by the methods and (ii) a surgical suturing kit that includes the dyed suture material.

The application relates to the technical field of medical data processing, and discloses a training method of a pathological image recognition model, a pathological image recognition method and device, the training method of the pathological image recognition model comprising the following steps: obtaining a plurality of histopathological image samples; for part or all of the histopathological image samples, converting a color space into an H&E space to obtain an initial H&E space image, the H&E space comprising two color channels, namely a hematoxylin color channel and an eosin color channel; for the initial H&E space image, using a B-spline curve function to perform dyeing enhancement processing or dyeing weakening processing on at least one color channel to obtain a target H&E space image; and using the histopathological image samples and the target H&E space image to train a pre-constructed histopathological image recognition model. The application can improve the generalization ability of the histopathological image recognition model, and further improve the accuracy.

This invention provides a method for detecting spatial proteomics and spatial phosphorylation modification omics. The method includes the following steps: (1) obtaining two consecutive sections of the target tissue and staining the sections with hematoxylin-eosin to obtain stained sections; (2) using a 3D printing mold to cut the stained sections into continuous, gapless strip-shaped subunits; (3) extracting peptides from the strip-shaped subunits and enriching the peptides by phosphorylation modification; (4) performing chromatographic separation and mass spectrometry detection on the phosphorylation-enriched peptides to obtain one-dimensional omics information of each strip-shaped subunit; (5) using the image of the stained sections as a spatial reference, reconstructing the one-dimensional omics information into a two-dimensional spatial distribution to obtain the spatial distribution of the target omics biomolecules. The method of this invention only requires two tissue sections to simultaneously obtain two-dimensional spatial proteomics and spatial modification omics results, which is friendly to small clinical samples.
