Objective To study the effect of Chinese medicines on diabetic gastroparesis of type 2 diabetes mellitus（T2DMDGP） through regulating qi circulation and to observe its influence on plasma motilin

gastric motivation and blood sugar.Methods The 136 T2DMDGP patients were randomized into a treatment group（64 cases） and a control group（72 cases）.Based on the same medication to control blood sugar

they were treated by traditional Chinese medicines on the principle of regulating qi circulation and Clebopride Malate Tablets respectively

and their plasma motilin

gastric motivation and blood sugar were determined for comparison.Results By gastrointestinal migrating motor complex（MMC） determination

the time of phase Ⅰ was obviously extended

the time of phase Ⅲ obviously shortened

while the time of phase Ⅱ not obviously changed

no significant difference found between two groups（P>0.05）.The clinical symptoms improved after treatment.The clinical recovered rate and total effective rate of the treatment groups was 65.63%

96.88% respectively

and that of the control group was 52.78% and 84.73% respectively

showing a significant difference（P<0.05）.The plasma motilin and blood sugar decreased obviously in the treatment group

the difference was significant as compared with before treatment（P<0.01 or P<0.05）.The MMC time phases improved in both groups

but the treatment group was obviously better than the control group（P<0.05）.Conclusion The Chinese medicines of regulating Qi circulation was effective in decreasing blood sugar

plasma motilin

strengthening gastric motivation of T2DM DGP patients.
