目的
2
观察电头针对缺血性脑卒中(IS)大鼠缺血皮层区干扰素γ(IFN-γ)、Janus激酶/信号转导和转录激活因子1(JAK/STAT1)信号通路及炎性因子的影响,探讨其缓解IS大鼠神经炎性损伤的分子机制。
方法
2
SD大鼠随机分为正常组、模型组、电头针组、抑制剂组,每组14只。采用线栓法复制大脑中动脉栓塞大鼠模型。抑制剂组腹腔注射抑制剂PJ34(25 mg/kg),1次/d,共7 d。电头针组取双侧“顶颞前斜线”予电头针干预,30 min/次,1次/d,共7 d。干预前和干预后,对各组大鼠行神经功能缺损评分及神经行为学评分;TTC染色法检测脑梗死体积;免疫组织化学法检测大鼠大脑皮层白细胞介素(IL)-6、IL-10的阳性表达;Western blot法检测大鼠大脑皮层IFN-γ、JAK1、JAK2和磷酸化(p)-STAT1蛋白的表达水平。
结果
2
与正常组比较,模型组神经功能缺损评分和神经行为学评分明显升高(
P
<
0.01),脑梗死体积明显增大(
P
<
0.01),脑组织IL-6、IFN-γ、JAK1、JAK2、p-STAT1表达水平升高(
P
<
0.01),IL-10表达水平降低(
P
<
0.01)。与模型组比较,干预后抑制剂组和电头针组神经功能缺损评分和神经行为学评分明显降低(
P
<
0.01),脑梗死体积减小(
P
<
0.01),脑组织IL-6、IFN-γ、JAK1、JAK2、p-STAT1表达水平降低(
P
<
0.01),IL-10表达水平升高(
P
<
0.01)。电头针在改善神经功能缺损评分和下调p-STAT1的表达方面优于抑制剂(
P
<
0.05,
P
<
0.01),在改善脑梗死体积和下调IFN-γ、JAK1方面不及抑制剂(
P
<
0.01,
P
<
0.05)。
结论
2
下调IFN-γ表达,进而抑制JAK/STAT1信号通路活性可能是电头针缓解IS神经炎性损伤的机制之一。
Objective
2
To explore the molecular mechanism of electrical stimulation with scalp acupuncture (ESA) in alleviating neuroinflammatory injury in ischemic stroke rats based on interferon γ (IFN-γ)-mediated Janus kinase/signal transduction and transcriptional activator 1 (JAK/STAT1) signaling pathway.
Methods
2
Fifty-six SD rats aged 7 weeks were randomly divided into normal, model, ESA and inhibitor groups, with 14 rats in each group. The middle cerebral artery embolization rat model was established by means of thread embolization. Rats in the inhibitor group were intraperitoneally injected with the inhibitor PJ34 (5 mg/mL, 25 mg/kg) once a day for 7 days. Rats in the ESA group were treated at bilateral anterior parietotemporal slash (MS6) with ESA (2 Hz/100 Hz, 1 mA), 30 min a day for 7 days. Before and after interventions, the neurological deficit score and neurobehavioral score were evaluated. The percentage of cerebral infarction volume was detected by TTC staining. The positive expressions of interleukin (IL)-6 and IL-10 in cerebral cortex were detected by immunohistochemistry. The protein expression levels of IFN-γ, JAK1, JAK2 and phosphorylated (p)-STAT1 in rats cerebral cortex were detected by Western blot.
Results
2
Compared with the normal group, the neurological deficit score, neurobehavioral score, the percentage of cerebral infarction volume, the expression levels of IL-6, IFN-γ, JAK1, JAK2 and p-STAT1 in cerebral cortex were increased (
P
<
0.01), while the expression level of IL-10 was decreased (
P
<
0.01) in the model group. Compared with the model group, the neurological deficit score and neurobehavioral score after treatment were significantly decreased (
P
<
0.01), the percentage of cerebral infarction volume was decreased (
P
<
0.01), the expression levels of IL-6, IFN-γ, JAK1, JAK2 and p-STAT1 in cerebral cortex were decreased (
P
<
0.01), while the expression level of IL-10 was increased (
P
<
0.01) in the ESA and inhibitor groups. ESA was superior to inhibitors in improving neurological deficit score and down-regulating p-STAT1 expression (
P
<
0.05,
P
<
0.01), and was inferior to inhibitor in reducing the percentage of cerebral infarction volume as well as down-regulating IFN-γ and JAK1 (
P
<
0.01,
P
<
0.05).
Conclusion
2
Down-regulating the expression of IFN-γ and inhibiting the activity of JAK/STAT1 signaling pathway may be one of the mechanisms by which ESA alleviates neuroinflammatory injury in ischemic stroke rats.
