The Biological Basis of Phlegm Dampness Syndrome in Patients With Ischemic Stroke：A Saliva and Urine Proteomics Study

The Biological Basis of Phlegm Dampness Syndrome in Patients With Ischemic Stroke：A Saliva and Urine Proteomics Study

This study aimed to explorie the biological basis of phlegm-dampness syndrome in patients with ischemic stroke using proteomics research techniques of urine and saliva.

Stroke is the disease with the highest mortality and disability in China, and the annual incidence of ischemic stroke is the highest. Atherosclerosis is the main cause of ischemic stroke. According to the theory of traditional Chinese medicine, the disease is closely related to the physical constitution of the individual. The main body constitution of the population in Lingnan area is phlegm dampness syndrome;Previous large cross-sectional studies have found that 65.3% of patients with ischemic stroke in Lingnan area have phlegm dampness syndrome. However, there is currently no biological evidence related to phlegm-dampness syndrome and ischemic stroke.In recent years, proteomics research technology has developed vigorously. The research samples have developed from blood obtained from minimally invasive to urine and saliva obtained non-invasively. Studies have found that urine proteins associated with AS include type I, type III collagen, 8-isoprostaglandin F2α, and saliva proteins include IL-1β, IL-6, TNF-α, and PGE2.Therefore, this research is dedicated to exploring the biological basis of phlegm-dampness syndrome in patients with ischemic stroke using proteomics research techniques of urine and saliva.
