Its pathogenesis is complex, involving multiple factors such as gene mutations, bile duct dysplasia, and infection. Traditional pathogenesis diagnosis methods, such as routine biochemical testing and imaging examination, have certain limitations and cannot accurately locate the cause of the lesion, which is prone to misdiagnosis or missed diagnosis. Tandem mass spectrometry technology has important value in the diagnosis of IBD pathogenesis as a fast and high-precision detection technology.This article introduces the basic principle of tandem mass spectrometry technology and its application in the diagnosis of IBD pathogenesis. Firstly, screen the pathogenic-related genes of IBD, and identify possible pathogenic gene mutations in the deep sequencing data; secondly, detect the metabolites or substances in blood or tissue samples through mass 精品文档--...
