Overview
Brief Summary
- Analysis of preoperative and postoperative metabolite changes: Through metabolomics technology, the changes of preoperative and postoperative metabolites in patients with colorectal cancer complicated with metabolic syndrome such as hypertension and diabetes were systematically analyzed, and the key metabolites related to postoperative remission were found.
- Explore the influencing factors of postoperative remission of metabolic syndrome: Combined with clinical data, the association between various metabolites and the degree of postoperative remission was evaluated, and the main factors affecting postoperative remission were determined.
To reveal the mechanism of the remission of metabolic syndrome after surgery: To clarify the metabolic pathways and mechanisms involved in the remission of metabolic syndrome after surgery through multi-level metabolomics analysis, and to provide a new theoretical basis for the development of tumor metabolic surgery.
Detailed Description
This study will continue for 2-3 years. All patients who meet the inclusion and exclusion criteria will be divided into hypertension group and diabetes group according to the type of metabolic syndrome, with 120 cases in each group. Blood and feces of all patients were collected before surgery, 3 days after surgery, 6 months after surgery, and 1 year after surgery. The collected samples will be subjected to untargeted metabolomics analysis, using NMR-IVDr technology to detect the dynamic changes of all small molecular metabolites (mainly endogenous small molecular compounds with relative molecular weight within 1000 Da) in blood and feces before and after stimulation or disturbance without bias. The differential metabolites of blood glucose, blood lipids, cholesterol, insulin, renin, aldosterone and angiotensin were screened by bioinformatics analysis, and the pathway analysis of differential metabolites was performed to reveal the potential physiological mechanism of postoperative hypertension, diabetes and other metabolic syndrome remission

Outcomes
Primary Outcomes
Metabolic disease remission
Time Frame: From date of surgery until the date of first documented postoperative complication, assessed up to 2 months after surgery.
Metabolic disease remission was defined as any remission of hypertention, diabetes, or fatty liver measured 2 months after surgery. Hypertension remission was defined as arterial blood pressure less than 140/90 mmHg measured postoperatively in patients with preoperative comorbid hypertension. Diabetes remission was defined as fasting blood glucose less than 6 mmol/L measured postoperatively in patients with preoperative comorbid diabetes. Fatty liver remission was defined as liver function in the normal range measured by postoperative blood tests in patients with preoperative comorbid fatty liver.
