Objective To observe the effect of auricular plaster therapy combined with traditional Chinese medicine on prediabetes. Methods 90 patients with prediabetes were randomly divided into control group and treatment group， each with a report of forty-five cases. The control group received general life intervention， including diet and exercise guidance， and diabetes health education； the treatment group was given Auricular Pressure Combined with traditional Chinese medicine（ten kinds of Jade Spring capsules） treatment based on the general life intervention. Fasting plasma glucose（FPG）， postprandial 2H blood glucose（2hPBG）， glycosylated hemoglobin（HbAlc）， total cholesterol（TC）， insulin resistance index（HOMA-IR）， and body mass index（BMI） before and after treatment in the two groups were observed. Results The reverse rate of prediabetes of the treatment group was significantly better than that of control group after treatment（P<0.01）， while there was no significant difference between the two groups in the incidence of diabetes mellitus after treatment（P>0.05）. The FPG， 2hPBG， HbAlc， TC， HOMA-IR， and BMI in the two groups significantly decreased after treatment（P<0.01）. The FPG， 2hPBG， HbAlc， TC， and HOMA-IR of the treatment group were significantly better than those of control group after treatment（P<0.01）， while there was no significant difference between the two groups in BMI（P>0.05）. Conclusion Auricular Pressure Combined with traditional Chinese medicine intervention in prediabetes， can reduce blood glucose and blood lipids， improve insulin resistance， promote the reversal of normal glucose tolerance， and reduce the incidence of diabetes， which is better than the simple life intervention.
