Relationship Among Oral Microbiome and NLRP3 Inflammatome and Colorectal Polyps

Sponsor: Limin Zhang

View on ClinicalTrials.gov

Summary

In this study, a case-control study was intended to establish a model for the combined diagnosis of colorectal polyps by detecting the expressions of oral and intestinal flora, ASC, Caspase-1, IL-1β and IL-18 in patients with colorectal polyps and healthy controls, as well as peripheral venous blood and intestinal tissue. To analyze the correlation between oral and intestinal specific flora and host inflammatory status, and explore the correlation between oral and intestinal flora, NLRP3 inflammatory complex, and colorectal polyps (pin-pin-two correlation), with a view to providing new biomarkers for the diagnosis and prognosis assessment of colorectal polyps from the perspective of oral and intestinal microorganisms and host immune inflammatory response. It also provides a new targeted treatment strategy for clinical prevention and treatment, and actively prevents the occurrence and development of colorectal polyp canceration.
