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(CV 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.
