针刺足阳明经穴对大鼠胃运动影响及其与P物质的关系

为了探讨针刺足阳明经穴有运动的调整作用是否与脑肠肽中的Ｐ物质（ＳＰ）有关。以乙醇灌胃造成大鼠胃粘膜损伤模型,气囊法测量胃运动频率和波幅的变化率,采用放免分析法（ＲＩＡ）检测大鼠胃窦及延髓ＳＰ含量。结果显示：模型组胃运动频率和波幅呈抑制状态,胃窦ＳＰ含量降低,延髓ＳＰ含量升高;针刺四白、天枢、足三里穴可促进胃运动恢复,且天枢、足三里组胃ＳＰ含量升高,延髓ＳＰ含量呈下降趋势,针刺非穴组对胃运动和ＳＰ影     

足阳明胃经与胃的相关性研究进展

从经络理论研究、机制研究和临床研究三方面对足阳明胃经与胃的相关性进行研究,发现胃在病理状态下,可出现阳明经穴物理特性的改变,而针刺可通过调节胃运动功能、平衡胃肠激素的分泌等途径改善胃肠功能,保护胃黏膜。针刺足阳明胃经穴位对胃调节作用具有相对特异性,可以有效治疗胃病。研究足阳明胃经与胃的相关性,对丰富经脉脏腑相关理论、指导针灸临床实践及提高疗效有着重要意义,能为阐明经络实质提供新的研究思路和方向。     

电针家兔足阳明经穴对穴区组织氧分压影响的研究

观察电针对家兔“足阳明经”穴内组织氧分压（Po2)的影响。选用新西半大耳白兔为对象，对“足阳明经”穴位梁门、天枢、足三里、解溪4穴及相应穴位左、右各旁开1cm对照线（点）共3组电针前后组织Po2的变化进行动态观察。结果显示：电针家兔“足阳明经”上述各穴点后其针后即刻与针前、针后15min与针前比较组织Po2值均明显降低（P＜0．05或0．01）。结论：（1）针刺能使经穴内的组织Po2明显降低，提示针刺作用的产生与所刺激穴位内氧的消耗加大、代谢旺盛密切相关；（2）经穴线与非经穴线比较其Po2的变化具有相对特异性，提示经络通路的存在。     

Effects of Electroacupuncture at Different Points on Colorectal Distention-induced Changes in Blood Pressure, Electrogastrogram, Gastric Tension and Gastric Blood Flow

Objective: To investigate the specificity of the effects of electroacupuncture (EA) at different acupoints on gastric functional activity and gastric blood flow after colorectal distension (CRD) in the rat. Methods: Fifty Wistar rats were randomly divided into 5 groups: a control group, a Zusanli group, a non-point group, a Taichong group and a Neiguan group. Rats were anesthetized after 18 h of fasting, and a rat model of nociceptive blood pressure elevation and abnormal electrogastrogram (EGG) and gastric tension (GT) was prepared by gasbag-induced CRD. EA was given bilaterally, and its effects on gastric blood flow (GBF) of the arcus vasculosi of the greater omentum, blood pressure, EGG fast wave properties, and gastric smooth muscle tension (GT) were quantified. Results: CRD induced an increase in blood pressure that was significantly inhibited by EA at all points (all P<0.05), and the inhibitory effects were greater in the Zusanli and Neiguan groups compared to the non-point group (both P<0.05). CRD also caused reductions in GT and GBF, and in the amplitude, frequency and duration of EGG waves (all P<0.05). These effects were also reversed by EA. The effects of EA on EGG wave amplitude, GT, and GBF were superior in the Zusanli group compared to the Taichong group, Neiguan group, and the non-point group. Conclusion: EA significantly counteracted CRD-induced changes in blood pressure, GBF, EGG, and GT. The effects of stimulation at Zusanli (ST 36) were significantly greater compared to other points, indicating relative specificity of this acupoint.

电针干预脊髓损伤大鼠受损节段缺氧诱导因子1α、血管内皮生长因子的表达

背景:作者发现,中医“痿病”从气血论治理论与脊髓损伤神经修复的关键环节在于改善组织血氧微环境有着惊人的相似,提出假设:电针刺激可通过干预缺氧诱导因子1α、血管内皮生长因子信号转导,改善脊髓血氧微环境从而促进神经再生。目的:探讨电针干预对脊髓损伤大鼠受损节段缺氧诱导因子1α、血管内皮生长因子表达的影响。方法:120只SD雌性大鼠以微型血管夹夹闭脊髓,保持夹闭状态20 s制作脊髓夹伤模型,随机分为3组:即阿是穴电针组、足阳明胃经电针组和空白对照组,每组40只。电针组造模后第3天开始接受每日1次的电针治疗,阿是穴电针组选择2个阿是穴、足阳明胃经电针组选择双侧伏兔、足三里穴,每周5次。于干预后1,2,3,4,5周对大鼠进行BBB评分之后分别取出损伤的脊髓组织标本,行病理组织观察,并采用免疫组织化学染色、实时荧光定量PCR技术及Western blot检测损伤脊髓缺氧诱导因子1α、血管内皮生长因子的基因和蛋白表达。实验方案经广西中医药大学第一附属医院动物实验伦理委员会批准(批准号201712001)。结果与结论:①阿是穴电针组及足阳明胃经电针组大鼠的下肢功能评分、缺氧诱导因子1α及血管内皮生长因子基因及蛋白表达明显高于未经电针干预的对照组;②随着干预时间的推移阿是穴电针组及足阳明胃经电针组的神经元数量均明显高于空白对照组;③结果说明,电针干预可以有效改善脊髓损伤大鼠的下肢功能评分、增加神经元的数量、上调缺氧诱导因子1α及血管内皮生长因子的mRNA及蛋白表达,从而有效促进脊髓神经功能的修复。
