A Study of Blood Metabolic Markers in Patients With Type 2 Diabetes Mellitus of Different Stages
Study Details
Study Description
Brief Summary
Metabolomics is an emerging "omics" after genomics, transcriptomics and proteomics, which can reflect the physiological state of organisms more directly and accurately. Whether metabolite differences exist in patients with type 2 diabetes of different stages and whether such metabolite differences can be used as potential markers have not yet been studied, which is of great significance to explore. In this study, 105 patients with different stages of type 2 diabetes mellitus were enrolled according to the inclusion and exclusion criteria, and the metabolites in the samples were detected by ultra-high performance liquid chromatography coupled with tandem time-of-flight mass spectrometry (UHPLC-Q-TOF MS) after the blood samples were collected, and the corresponding investigative data were collected, and then baseline and demographic analyses, metabolomics data processing, and analysis of the results were carried out to provide a reference for the identification of metabolic markers and to provide a reference for the identification of significant metabolic markers in diabetic patients.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Pre-diabetes Fasting blood glucose level of 5.6-6.9 mmol/L (impaired fasting blood glucose) or 2-hour postprandial blood glucose of 7.8-11.0 mmol/L (impaired glucose tolerance) or haemoglobin A1c (HBA1c) of 5.7-6.4%. |
Other: No intervention
No intervention
|
| Diabetes in the early stages Fasting blood glucose is higher than 7.0mmol/L, 2 hours postprandial blood glucose is higher than 11.1mmol/L, random blood glucose is higher than 11.1mmol/L with classic symptoms of hyperglycemia, and the HbA1C is higher than 6.5%, but there is no obvious complication of heart, kidney and eyes. |
Other: No intervention
No intervention
|
| Diabetes in the middle and late stages Includes diabetics with various degrees of complications. Among the minor complications are microalbuminuria and mild diabetic retinopathy (e.g. microaneurysms, mild haemorrhages). Mild to moderate complications included diabetic nephropathy without renal failure and diabetic retinopathy without proliferative diabetic retinopathy. Severe complications include hyperglycaemic crises such as diabetic ketoacidosis and hyperosmolar hyperglycaemic state, microvascular complications such as retinopathy (neovascularisation and vitreous or preretinal haemorrhage preretinal haemorrhage), nephropathy, cardiomyopathy, neuropathy (sensory lesions such as podiatry, autonomic neuropathies such as sexual dysfunction and gastroparesis), and macrovascular complications (coronary heart disease, cerebrovascular disease, proliferative diabetic retinopathy, peripheral arterial disease, amputations and foot ulcers). |
Other: No intervention
No intervention
