摘要

Metabolite signatures of acupoints. ( ) Base-peak-ion chromatograms of electroacupuncture in the sham, ST36, and PC6 groups for the cerebral cortex, hippocampus, and hypothalamus, respectively. ( ) PLS-DA plot of the cerebral cortex, hippocampus, and hypothalamus of rats presenting the difference of metabolite profiles in the sham, ST36, and PC6 groups.
