Our data showed that the total effective rate of treatment group was 66.67%, and body weight and body mass index after treatment the body were significantly decreased （P〈0.01）. The levels of total cholesterol, triglyceride, high-density lipoprotein and low-density lipoprotein after treatment were lower than before treatment, but there was no statistical difference （P〉0.05）. The total effective rate of control group was 39.13%, and the body weight and body mass index atter treatment were also significantly lower than before （P〈0.01）.
