Electroacupuncture improves neurovascular unit reconstruction by promoting collateral circulation and angiogenesis

Acupuncture at Shuigou（GV26） shows good clinical efficacy for treating stroke, but its mechanism remains poorly understood. In this study, a cerebral infarction model of ischemia/reperfusion injury received electroacupuncture at GV26（15 Hz and 1 m A, continuous wave [biphasic pulses], for 5 minutes）. Electroacupuncture effectively promoted regional cerebral blood flow on the infarct and non-infarct sides, increased infarct lesions, lectin, and number of blood vessels, upregulated von Willebrand factor and cell proliferation marker Ki67 expression, and diminished neurological severity score. These findings confirm that electroacupuncture at GV26 promotes establishment of collateral circulation and angiogenesis, and improves neurological function.

Electroacupuncture Promotes Angiogenesis in Mice with Cerebral Ischemia by Inhibiting miR-7

Objective To observe the angiogenesis effect of electroacupuncture(EA)at Shuigou acupoint(GV 26)in the treatment of cerebral ischemia,and explore the value of miRNA-7(miR-7)in it.Methods First,48 mice were randomly divided into sham operation,middle cerebral artery occlusion(MCAO)model,and EA treatment groups.Then 9 mice were divided into carrier control group,miR-7 knockout group and miR-7 overexpression group(n=3 each group).Finally,20 mice were divided into model and carrier control group,model and miR-7 knockout group,EA treatment and carrier control group and EA treatment and miR-7 overexpression group,with 3–6 mice in each group.The MCAO model was established in the MCAO and EA groups.Neurological deficit score and 2,3,5-triphenyltetrazolium chloride(TTC)staining were used to evaluate the severity of cerebral ischemia.Hematoxylin-eosin staining was used to describe basic pathological changes.Immunohistochemistry was used to quantify cerebral microvessel density.Real-time PCR and Western blot were used to detect the expression of miR-7 and its downstream target genes Krüppel-like factor 4/vascular endothelial growth factor(KLF4/VEGF)and angiopoietin-2(ANG-2)in the ischemic cerebral cortex.Results After EA,neurological deficit scores and infarction volumes decreased,and the density of cerebral microvessels increased.In the MCAO group,miR-7 expression was higher than that in the sham group(P<0.01).After EA at GV 26,miR-7 expression decreased(P<0.01)and the expression of downstream target genes KLF4/VEGF and ANG-2 increased as compared with the MCAO group(P<0.01).After EA combined with overexpression of miR-7,the expression of downstream target genes KLF4/VEGF and ANG-2 decreased compared to the control EA group(P<0.01).After miR-7 knockdown,the expression of KLF4/VEGF and ANG-2 increased(P<0.05 or P<0.01).Conclusions EA could promote angiogenesis in MCAO mice likely by inhibiting the expression of miR-7 and relieving inhibition of downstream target genes KLF4/VEGF and ANG-2.

Molecular Mechanism of Electroacupuncture Regulating Cerebral Arterial Contractile Protein in Rats with Cerebral Infarction Based on MLCK Pathway

Objective To explore the effect of electroacupuncture(EA)intervention on the vasoconstriction of cerebral artery smooth muscle cells after cerebral infarction.Methods Male Wistar rats were randomly divided into 3 groups by a random number table:the model group(n=24),the EA group(n=24),and the normal group(n=6).The model and the EA groups were divided into different time subgroups at 0.5,1,3,and 6 h after middle cerebral artery occlusion(MCAO),with 6 rats in each subgroup.MCAO model was established using intraluminal suture occlusion method.The EA group was given EA treatment at acupoint Shuigou(GV 26)instantly after MCAO for 20 min.The contents of cerebrovascular smooth muscle MLCK,the 3 subunits of myosin light chain phosphatase(MLCP)MYPT1,PP1c-δand M20,as well as myosin-ATPase activity were detected using immunohistochemistry and Western blotting.Results The overall expression level of the MYPT1 and PP1c-δin the model group was significantly higher(P<0.01).After EA intervention,the 0.5 h group expression level was close to that of the normal group(P>0.05),and the other subgroups were still significantly higher than the normal group(P<0.01).After EA intervention,the expression level of each subgroup was significantly lower than the corresponding model group.There was a significant difference between the 0.5 and 1 h subgroups(P<0.01),while a difference was also observed between the 3 and 6 h subgroups(P<0.05).The dynamic change rule gradually increased with the prolongation of infarction time within 6 h after infarction.Conclusion EA intervention can inhibit contraction of cerebral vascular smooth muscle cells and regulate smooth muscle relaxation by regulating MLCK pathway.
