Objective To explore the possible mechanism of acupuncture treating vascular dementia( VD).Methods Twenty-four rats were randomized into sham operation group
model group
acupuncture group and non acupoint group with 6 rats in each group. Except the sham operation group rats in other groups were built VD rat models using permanent bilateral common carotid artery ligation method. Cortical neuron morphological changes were examined by Nissl stain. Cortical neuron apoptosis were examined by TUNEL method. The expression of phosphorylation c-Jun NH2-terminal Kinase( p-JNK) was examined by immunofluorescence technique. Results Compared with the sham operation group
the model group rats’ cortical cells were scattered
nucleus pyknosis and deep staining. Cortical neuron apoptosis and p-JNK expression increased( P < 0. 05). Compared with the model group
the acupuncture group rats’ cortical neuron morphology improved. Neuron apoptosis and p-JNK expression decreased( P < 0. 05). There was no obvious improvement in the non acupoint group. Conclusion Acupuncture might inhibit the expression of p-JNK in cortex of VD rats. Reducing cortical neuron apoptosis might be one of the mechanisms of treating VD.
