A Prospective, Open, Self-controlled Study of the Effects of Chiglitazar Sodium on Glucose and Lipid Metabolism in Patients With Type 2 Diabetes Mellitus (T2DM)

The goal of this clinical trial is to learn about inour study aimed to evaluate serum lipid profiles of T2DM patients before and after Chiglitazar Sodium administration.

The main question\[s\] it aims to answer are:

* Quantitative lipidomics information enables in-depth analysis of lipids and can reveal Chiglitazar Sodium-specific lipid metabolic patterns, thereby strengthening lipidomics as a promising tool for exploring the molecular mechanisms of T2DM.
* It can also be applied to other T2DM lipidomics studies to better understand lipid metabolism patterns and integration with other omics measures.

Chiglitazar Sodium for lipid profile abnormalities and its associated effective lipid molecular biomarkers have never been studied in patients with T2DM. Therefore, our study aimed to evaluate serum lipid profiles of T2DM patients before and after Chiglitazar Sodium administration using ultra-high performance liquid chromatography-Tandem quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS). For completeness, we also evaluated the effects of Chiglitazar Sodium treatment on metabolic markers associated with T2DM and its association with lipidomic changes.
