简要总结
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.

入选标准
- •Case group: Patients diagnosed with colorectal polyps by enteroscopy in the gastroenterology department of our hospital were collected. For patients with two or more different types of histopathological examination results, all cases containing tubular adenoma, tubular villous adenoma and villous adenoma were classified into the adenoma group.
- •Control group: Age - and sex-matched family members of the patient were selected, and no enteric-related diseases were detected by colonoscopy.
