[Effects of acupoint injection of autologous blood on symptoms and plasma motilin and gastrin levels of diabetic gastroparesis patients].

Objective: To observe the curative effect of autologous blood point injection on diabetic gastroparesis and to study its underlying mechanism.

Methods: A total of 42 type-II diabetes outpatients and inpatients were randomly and equally divided into treatment group and control group according to a random digit table. Patients of the treatment group were treated by injection of the patient's own venous blood (2 mL/acupoint) into the unilateral Zusanli (ST 36), Zhongwan (OV 12) and Weishu (BL 21), once every week, 4 times together. Patients of the control group were ordered to take motilium (10 mg/time), 3 times daily for 4 weeks. Plasma motilin and gastrin were detected by radioimmunoassay before and 4 weeks after the treatment.

Results: Of the two 21 cases in the control and treatment groups, 3 and 7 experienced marked improvement in their symptoms, 4 and 8 were effective, 14 and 6 were failed in the treatment, with the effective rates being 33.3% and 71.4% respectively. The effective rate of the treatment group was significantly higher than that of the control group (P<0.05). The contents of plasma motilin and gastrin in both control and treatment groups were reduced obviously after the treatment (P<0.01), and the effect of the treatment group was significantly superior to that of the control group in lowering plasma motilin and gastrin levels (P<0.01).

Conclusion: Acupoint injection of the diabetes patients' own blood can obviously alleviate the symptoms of diabetic gastroparesis, which is closely associated with its effects in lowering plasma motilin and gastrin levels.
