Overview
This study is a prospective observational study. The study will explore the correlation between advanced glycation end products and gastric motility disorder in diabetic gastroparesis（DGP) through the collection of blood and gastric tissue samples and relevant data of patients with DGP and control group patients without diabetes history and gastroparesis symptoms.
Description
This study will collect the gastric smooth muscle tissue and serum of patients with diabetic gastroparesis（DGP) and control group patients without diabetes history and gastroparesis symptoms, and collect the following patient related information: age, gender, height, weight, fasting blood glucose, diabetes course, glycosylated hemoglobin, fasting C-peptide, serum creatinine, and electrogastrogram results.
The study will compare the score of gastroparesis cardinal symptom index scale and electrogastrogram results of patients with DGP and and control group patients without diabetes history and gastroparesis symptoms, detect and compare the difference in the expression of contractile protein in the muscle layer of gastric tissue of the two groups, detect and compare the difference in advanced glycation end products (AGEs) of serum and gastric tissue of the two groups, and analyze the correlation between serum and gastric tissue AGEs and clinical symptoms. Through the above results, we will clarify the correlation between AGEs and gastric motility disorders in DGP.
