This invention discloses a method and system for batch conversion of bulb flat steel interfaces into angle steel or T-sections. It utilizes the LISP programming language and dynamic block technology in AutoCAD software, and involves secondary development of functional modules capable of automatically identifying bulb flat steel and batch replacing it with angle steel or T-sections during the ship design phase. Different specifications and patch forms of profile interfaces are drawn on a computer and integrated into dynamic blocks for angle steel, T-sections, and bulb flat steel using dynamic block technology. The system automatically identifies various forms of bulb flat steel in the original drawings according to set rules, calculates the base point, web angle, and bulb head orientation of each bulb flat steel, and batch replaces them with dynamic blocks of the same attributes. A dynamic block modification interface is developed to quickly modify profile specifications and patch forms. This invention enables automatic identification and batch replacement of bulb flat steel with angle steel or T-sections during the ship design phase using a computer, reducing the amount of repetitive manual drawing work for designers and laying the foundation for subsequent rapid modification of aggregate types.

This invention belongs to the field of biomedical technology, specifically relating to a method and kit for improving the sensitivity and specificity of circulating tumor cell (CTC) detection. The method first treats anticoagulated blood with erythrocyte lysis buffer, centrifuges to obtain a cell suspension (including leukocytes and circulating tumor cells); then, a radiosensitizer is added and the suspension is irradiated; next, single-cell gel electrophoresis is used to detect the degree of DNA damage in the test cells; finally, leukocytes and tumor cells are distinguished based on cell morphology using a fluorescence microscope or fluorescence scanner. This invention is the first to detect the number and type of circulating tumor cells (CTCs) in peripheral blood based on ionizing radiation and radiosensitization effects, according to the degree of DNA damage in tumor cells. Compared with existing technologies, this detection method and kit are not only simple and rapid, but also significantly improve detection sensitivity and specificity. Furthermore, it is independent of the physical properties of cells and tumor cell surface markers, requires a small sample volume, is highly versatile, and can detect CTCs in different types of solid tumors.
