Application of gene marker in early screening of esophagus, stomach and intestine multiple cancer species, early screening model construction method and detection device

The invention discloses application of a gene marker in early screening of esophagus, stomach and intestine multiple cancer species, an early screening model construction method and a detection device, and belongs to the technical field of early noninvasive detection of digestive tract tumors. By analyzing the whole genome characteristics of circulating free DNA in peripheral blood, a novel multi-cancer-species screening system is established. On the basis of low-depth whole genome sequencing data, molecular markers in three dimensions, namely a genome copy number variation mode, a DNA fragment distribution characteristic with a specific length and an epigenetics signal of a transcription initiation region, are emphatically detected. An advanced converter neural network architecture is adopted, and the model can efficiently capture complex feature association in a whole genome range through a specific self-attention mechanism. The model design particularly considers the particularity of genome data, introduces an adaptive position coding system, and accurately reflects the spatial distribution relationship of DNA fragments on chromosomes. Therefore, the system can still maintain excellent detection performance under extremely low sequencing depth.

This invention belongs to the field of medical drainage technology, specifically a drainage device for the care of gastrointestinal tumors. It includes a valve assembly, a valve adjustment assembly, an automatic cleaning assembly, a frame assembly, a liquid storage assembly, and a gas filtration assembly. The valve assembly is mounted on the frame assembly, and the valve adjustment assembly and the automatic cleaning assembly are located within the valve assembly. This invention cleverly utilizes changes in negative pressure within the valve body to trigger a cleaning action. When deposits on the inner wall obstruct the airflow, the reduced air pressure automatically overcomes the spring force, causing the piston to slide. This, in conjunction with a scraper ring, mechanically scrapes away the blockage from the inner wall of the valve body and pushes the obstruction into an independent storage bottle. This process achieves in-situ unblocking without disassembling the tubing, effectively preventing drainage interruption and significantly reducing the probability of cross-infection.
