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

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

Methods： Fifty patients suffering from VD were divided into 5 groups randomly and treated by conventional acupuncture for hemiplegia, or conventional acupuncture plus needling in DU20, DU26, HT7 respectively or simultaneously. Clinical symptoms were observed, and the scales such as Hasegawa＇s dementia scale-recension （HDS-R）, activities of daily living （ADL） and functional activities questionnaire （FAQ） were used for assessment before and after acupuncture treatment. The scores were processed statistically. Results： DU20 and HT7 could improve the abilities of memory, orientation, reaction and reduce adamancy and trance. Bedsides, DU 20 was helpful in improving the abilities of understanding, calculating and social adapting. While DU26 is helpful in treating retardation, failure in daily activities, trance and poor memory. The combination of the 3 acupoints could improve the intelligence and social adapting ability of VD patients. Conclusion： DU20, DU26 and HT7 had its own effect in treating VD, but the effect of three points used in combination was the best.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
