Effect of herb-partitioned moxibustion at fanwei point on plasma motilin and serum gastrin in patients of diabetic gastroparesis

Abstract

To explore the clinical therapeutic effect of herb-partitioned moxibustion at fanwei point in patients of diabetic gastroparesis differentiated as spleen and stomach deficiency and retention of turbid dampness as well as its effect mechanism. A total of 134 patients with diabetic gastroparesis were randomized into an observation group and a control group, 67 cases in each one. In the observation group, herb-partitioned moxibustion at fanwei point was adopted, 40 min each time, once a day for 5 times a week. In the control group, itopride hydrochloride tablets were prescribed for oral administration, 50 mg each time, three times a day. A total of 6 weeks of treatment was required in the two groups. Before and after treatment, the gastroparesis cardinal symptom index (GCSI) scores, 4-hour gastric emptying rate, TCM symptom score, as well as the levels of plasma motilin and serum gastrin were observed in the patients of the two groups. Additionally, the clinical therapeutic effect was evaluated in the two groups. After treatment, the score of every item of GCSI, TCM symptom scores and the levels of plasma motilin and serum gastrin were all reduced as compared with those before treatment in the patients of the two groups (P<0.05), and those in the observation group were lower than the control group (P<0.05). Regarding 4-hour gastric emptying rates, which were increased as compared with those before treatment in the two group (P<0.05), and the rate in the observation group was higher remarkably than that in the control group (P<0.05). The total effective rate was 92.5% (62/67) in the observation group, higher than 74.6% (50/67) in the control group (P<0.05). Herb-partitioned moxibustion at fanwei point relieves the clinical symptoms in the patients with diabetic gastroparesis and increases the gastric emptying rate, which is probably related to the regulation of the levels of plasma motilin and serum gastrin.
