背景:病理情况下,细胞间黏附因子1表达明显升高,促进炎症反应的发生,加重脑组织损伤。<br> 目的:观察眼针穴区、穴区外治疗对急性脑缺血再灌注损伤模型大鼠海马组织细胞间黏附因子1表达的影响。<br> 方法:40只SD大鼠随机等分为正常组、假手术组、模型组、眼针穴区组和穴区外组。后3组用线栓法复制脑缺血再灌注损伤大鼠模型,栓塞线插入深度1.8-2.2 cm,眼针组于脑缺血再灌注即刻及取材前30 min,取肝区、上焦区、下焦区、肾区平刺眼眶周治疗20 min。穴区外组选择眼针同名穴区的外3 mm处为针刺部位,刺法与眼针穴区相同。<br> 结果与结论:眼针穴区治疗后大鼠神经功能缺损评分下降,海马组织细胞间黏附因子1蛋白及mRNA表达显著降低(P <0.01)。穴区外组治疗后大鼠神经功能缺损评分及海马组织细胞间黏附因子1蛋白及mRNA表达无明显变化。提示眼针具有明显的改善大鼠脑缺血再灌注损伤的作用,其机制与下调海马组织细胞间黏附因子表达有关。
揹景:病理情況下,細胞間黏附因子1錶達明顯升高,促進炎癥反應的髮生,加重腦組織損傷。<br> 目的:觀察眼針穴區、穴區外治療對急性腦缺血再灌註損傷模型大鼠海馬組織細胞間黏附因子1錶達的影響。<br> 方法:40隻SD大鼠隨機等分為正常組、假手術組、模型組、眼針穴區組和穴區外組。後3組用線栓法複製腦缺血再灌註損傷大鼠模型,栓塞線插入深度1.8-2.2 cm,眼針組于腦缺血再灌註即刻及取材前30 min,取肝區、上焦區、下焦區、腎區平刺眼眶週治療20 min。穴區外組選擇眼針同名穴區的外3 mm處為針刺部位,刺法與眼針穴區相同。<br> 結果與結論:眼針穴區治療後大鼠神經功能缺損評分下降,海馬組織細胞間黏附因子1蛋白及mRNA錶達顯著降低(P <0.01)。穴區外組治療後大鼠神經功能缺損評分及海馬組織細胞間黏附因子1蛋白及mRNA錶達無明顯變化。提示眼針具有明顯的改善大鼠腦缺血再灌註損傷的作用,其機製與下調海馬組織細胞間黏附因子錶達有關。

BACKGROUND:Significant increasing of intercel ular adhesion molecule 1 expression can promote the occurrence of inflammatory response and increase brain tissue injury. <br> OBJECTIVE:To investigate the effect of eye acupuncture point and non-point therapy on intercel ular adhesion molecule 1 expression in rat hippocampus of acute cerebral ischemia-reperfusion injury model. <br> METHODS:Forty Sprague Dawley rats were divided into normal group, sham-operation group, model group, eye acupuncture point group and eye acupuncture non-point group. Rats in the model group, eye acupuncture point group and eye acupuncture non-point group were used to establish the acute cerebral ischemia-reperfusion injury model with suture method, the suture was deep for 1.8-2.2 cm. In the eye acupuncture point group, the acupuncture points of hepatic region, upper energizer area, lower energizer area and kidney area were selected when cerebral ischemia-reperfusion occurred immediately and 30 minutes before drawing materials, then horizontal needling the acupuncture points around the orbit for 20 minutes. In the eye acupuncture non-point group, the puncture site was selected at 3 mm away from eye acupuncture non-point area, and then needled the puncture site with the same method in the eye acupuncture point group. <br> RESULTS AND CONCLUSION:After eye acupuncture point therapy, the neurological deficit scores were decreased, and the intercel ular adhesion molecule 1 expression in rat hippocampus was significantly decreased (P<0.01). After eye acupuncture non-point therapy, there were no significant changes in neurological deficit scores and the expression of intercel ular adhesion molecule 1 protein and mRNA in rat hippocampus. The results indicate that eye acupuncture can significantly improve the rat cerebral ischemia-reperfusion injury, and the mechanism may relate with reducing the intercel ular adhesion molecule 1 expression in rat hippocampus.
