Repairing brain damage by inhibiting the macrophage-inducible C-type lectin/spleen tyrosine kinase （Mincle/Syk） signaling pathway is a potential new target for treating cerebral hemorrhage. In this study, we aimed to determine whether acupuncture through Baihui （DU20） to Qubin （GBT） is an effective treatment for intracerebral hemorrhage through the Mincle/Syk signaling pathway. An intracerebral hemorrhage rat model was established by autol- ogous blood infusion into the caudate nucleus. Acupuncture through Baihui to Qubin was performed for 30 minutes, once every 12 hours, for a total of three times. Piceatannol （34.62 mg/kg）, a Syk inhibitor, was intraperitoneally injected as a control. Modified neurological severity score was used to assess neurological function. Brain water content was measured. Immunohistochemistry and western blot assay were used to detect immunoreactivity and protein expression levels of Minde, Syk, and CARD9. Real-time polymerase chain reaction was used to determine interleukin-1[~ mRNA levels. Hematoxylin-eosin staining was performed to observe histopathological changes. Our re- suits showed that acupuncture through Baihui to Qubin remarkably improved neurological function and brain water content, and inhibited immunoreactivity and expression of Mincle, Syk, CARDg, and interkeukin-1β Moreover, this effect was similar to piceatannol. These find- ings suggest that acupuncture through Baihui to Qubin can improve neurological impairment after cerebral hemorrhage by inhibiting the Mincle/Syk signaling pathway.展开更多

Neurological deficit scores, western blotting, and reverse transcription-PCR results demonstrated that electroacupuncture markedly reduced neurological deficits, decreased corpus striatum aquaporin-4 protein and mRNA expression, and relieved damage to the blood-brain barrier in a rat model of cerebral ischemia/reperfusion injury. These results suggest that electroacupuncture most likely protects the blood-brain barrier by regulating aquaporin-4 expression following cerebral ischemia/reperfusion injury.展开更多

We established a rat model of Alzheimer＇s disease by injecting β-amyloid 1-42（Aβ1-42） into the bilateral hippocampal dentate gyrus to verify which frequency may be better suited in treatment. Electroacupuncture at 2 Hz or 50 Hz was used to stimulate Baihui（DU20） and Shenshu（BL23） acupoints. The water maze test and electrophysiological studies demonstrated that spatial memory ability was apparently improved, and the ranges of long-term potentiation and long-term depression were increased in Alzheimer＇s disease rats after electroacupuncture treatment. Moreover, the effects of electroacupuncture at 50 Hz were better than that at 2 Hz. These findings suggest that high-frequency electroacupuncture may enhance hippocampal synaptic transmission and potentially improve memory disorders in Alzheimer＇s disease rats.展开更多

However, most studies of the underlying mechanism are at the single gene level; there are few reports regarding the mechanism at the whole-genome level. Using a rat genomic gene-chip, we profiled hippocampal gene expression changes in rats after electroacupuncture therapy. Electroacupuncture therapy alleviated depres- sion-related manifestations in the model rats. Using gene-chip analysis, we demonstrated that electroacupuncture at Baihui （DU20） and Yintang （EX-HN3） regulates the expression of 21 genes. Real-time PCR showed that the genes Vgf, lgf2, Trnp32, Loc500373, Hifla, Folrl, Nrnb, and Rtn were upregulated or downregulated in depression and that their expression tended to nor- malize after electroacupuncture therapy. These results indicate that electroacupuncture at Baihui and Yintang modulates depression by regulating the expression of particular genes.展开更多
