Abstract:Objective To investigate the effects of Houpo Paiqi Mixture on gastrointestinal hormones, gastrointestinal dynamics and oxidative stress in elderly patients with type 2 diabetic gastroparesis.Methods The 80 elderly patients with type 2 diabetic gastroparesis in Zhejiang Provincial People's Hospital from June 2019 to June 2020 were randomly divided into experimental group (40 cases) and control group (40 cases). The two groups of patients continued to receive insulin injection or oral hypoglycemic drugs and other conventional hypoglycemic therapy, with appropriate exercise and reasonable diets. The control group was treated with Mosapride tablets, while the experimental group was treated with Houpo Paiqi Mixture on the basis of the treatments in the control group. The treatment course of the two groups was 4 weeks. The overall effective rate was compared between the two groups after 4 weeks of treatment; the changes in main symptom scores, gastrointestinal hormones, gastrointestinal dynamics and oxidative stress levels before and after 4 weeks of treatment were compared.Results The overall effective rate of experimental group (92.50%) was higher than that of control group (70.00%) (P < 0.05). The differences of fasting blood glucose (FBG), two-hour postprandial glucose (2 hPG) and glycated hemoglobin (HbA1c) before and after treatment in the experimental group were higher than those in the control group (P < 0.05). The differences of epigastric fullness, anorexia and belching scores before and after treatment in the experimental group were higher than those in the control group (P < 0.05). The differences of somatostatin, motilin and gastrin levels before and after treatment in the experimental group were higher than those in the control group (P < 0.05). The differences of gastric emptying time, gastric emptying rate and gastric contraction frequency before and after treatment in the experimental group were higher than those in the control group (P < 0.05). Besides, the differences of superoxide dismutase (SOD) and glutathione peroxidase (GSH-PX) levels before and after treatment in the experimental group were higher than those in the control group (P < 0.05).Conclusions Houpo Paiqi Mixture shows great therapeutic efficacy in elderly patients with type 2 diabetic gastroparesis, improves gastrointestinal hormones and gastrointestinal dynamics, and regulates the level of oxidative stress.
