Objective To observe the influence of acupuncture on glucose and lipid metabolism and insulin sensitivity.Methods Seventy-on e metabolic syndrome patie nts were randomized into treatment group（37 cases） and control group（34 cases）.The treatment group was given acupuncture on the back-shu points including Ganshu（BL18）

Feishu（BL13）

Weishu（BL21）

Sanjiaoshu（BL22）

Pishu（BL20）

Geshu（BL17）

Shenshu（BL23）

combined wit h Zusanli（ST36）

Neiguan（PC6） and Sanyinjiao（SP6）.The patients in the con trol group was orally taken 0.5g of metformin

three times daily.After 12 weeks

body mass index（BMI）

insulin sensitivity index（ISI）

serum triglycerides（TG）

high-density lipoprotein cholesterol（HDL-C）

total cholesterol（TC） and blood pressure were observed.Result s The total effective rate of the treatment group was 91.89%

and that of the control group was 50%.The difference was statistically significant between two groups（P<0.05）.Comparing with before treatment

the differences of ISI

systolic blood pressure

BMI and blood lipid were statistically signif icant in the treatment group（P<0.05）

but there was no statistical significance in the control group（P>0.05）.The differences of the index mentioned above wer e statistically significant between groups after treatment（P<0.05）.Conclusion Acupu ncture is effective for metabolic syndrome with a better effect on reducing blood glucose and improving ISI as well as lipid metablism
