Molecular weight statistical recognition method, system, and device for sugar in blood of pancreatic cancer blood and medium

Abstract

The invention provides a molecular weight statistical identification method, system and device for sugar in pancreatic cancer blood and a medium. The method comprises the following steps: receiving amolecular weight data set of sugar in the blood of a pancreatic cancer patient, a molecular weight data set of sugar in blood of a healthy person and a molecular weight data set of sugar in blood of aperson to be examined; calculating a mean square error Dy (p, b) of the molecular weight of the sugar in the blood of the pancreatic cancer patient; calculating a mean square error Dy (p, a) of the molecular weight of the sugar in the blood of the healthy person; calculating a mean square error Dy (p, b ') of the molecular weight of the sugar in the blood of the first person to be examined; calculating a mean square error Dy (p, a ') of the molecular weight of the sugar in the blood of the second person to be examined, wherein | Dy (p, b)-Dy (p, b ') | is a first absolute value and | Dy (p, a)-Dy (p, a ') | is a second absolute value; and judging whether the person to be examined suffers from pancreatic cancer or not by comparing the sum of the first absolute values with the sum of the second absolute values. The molecular weight statistical recognition method, system, and device for the sugar in the pancreatic cancer blood and the medium are used for molecular weight data of the sugar in the blood, a statistical mathematical model is established, and a mean variance pancreatic cancer recognition method high in recognition rate is created.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a molecular weight statistical identification method, system, medium and device for sugar in pancreatic cancer blood. Background technique [0002] Pancreatic cancer causes death. Pancreatic cancer patients often have abnormal sugar groups, one of which is N-glycan abnormality. Studying the abnormal expression of N-glycan is an important way to identify pancreatic cancer. In the serum of pancreatic cancer patients, N-glycans are significantly abnormally expressed, and the molecular weight of sugar in blood is an important indicator for identifying pancreatic cancer. Therefore, in the research of pancreatic cancer in recent years, N-glycans in serum are the research hotspots for identifying molecular markers of cancer. The N-glycan research of Rudd et al. pointed out that N-glycan is an important molecular marker of cancer, which is especially suitable for early diagnosis...

Problems solved by technology

However, while the abnormal expression of N-glycans caused by cancer has been widely concerned, the association between N-glycans and cancer stages has been rarely reported
