Abstract
目的:采用核磁共振氢谱技术(1H; NMR)研究电针胃经穴对应激性胃溃疡大鼠胃黏膜组织代谢物谱的表达。方法:40只SD大鼠随机分为正常组、模型组、胃经组和胆经组。利用束缚-冷应激法; 制备应激性胃溃疡模型大鼠,光镜下观察大鼠胃黏膜组织病理形态学的变化,采用1H NMR技术获取胃黏膜组织1H; NMR谱,并利用模式识别方法分析各组间的代谢物谱的差异。结果:与正常组比较,模型组大鼠胃黏膜损伤和胃黏膜组织代谢轮廓差异明显,胃黏膜组织乙酸、肌; 醇、磷酸胆碱、谷氨酸、甘氨酸、乙醇胺、赖氨酸、3-羟基丁酸、缬氨酸、异亮氨酸、牛磺酸、亮氨酸和甘露醇含量上升(P<0.05),乳酸、甲硫氨酸和天; 冬氨酸含量下降(P<0.05);与模型组比较,胃经组和胆经组大鼠胃黏膜得到明显修复,胃经组大鼠胃黏膜组织代谢轮廓更接近正常大鼠,胃黏膜组织甲硫氨; 酸、天冬氨酸含量上升(P<0.05),乙酸、肌醇、磷酸胆碱、谷氨酸、甘氨酸、赖氨酸、异亮氨酸、牛磺酸、乳酸、亮氨酸和甘露醇含量下降(P<0.05; );胆经组大鼠胃黏膜组织3-羟基丁酸、甲硫氨酸含量上升(P<0.05),肌醇、磷酸胆碱、谷氨酸、乙醇胺、异亮氨酸、乳酸、亮氨酸和甘露醇含量下降(; P<0.05)。结论:电针胃经穴可调节胃溃疡大鼠胃黏膜组织特异代谢物的表达,促进胃黏膜损伤的修复。
 
Objective: To research the effects of electropuncture of acupoints on; the foot Yangming stomach meridian on metabolic profiling of gastric; mucosa in rats of gastric ulcer induced by stressusing the 1H nuclear; magnetic resonance (1H NMR). Methods: Forty SD rats were randomly; divided into the control group, the model group, the stomach meridian; group and the gallbladder meridian group. The rat model of gastric ulcer; was induced by the restrained plus cold stress. The pathological changes; in the rat gastric mucosa tissue were observed by light microscope. The; 1H NMR spectroscopy was determined with the 1H NMR technique. And,; meanwhile the differences in the metabolic profiling were identified; with the pattern recognition method. Results: Compared to normal group,; the gastric mucosa damage and gastric mucosa metabolic profiling are; obvious, the concentration of acetic acid, choline, inositol phosphate,; glutamic acid, glycine, ethanolamine, lysine, 3-hydroxy butyric acid,; valine, isoleucine, taurine, leucine and mannitol increase and the; concentration of lactic acid, methionine and aspartic acid decrease in; model group rats (P<0.05). Compared to model group, the gastric mucosa; damage have been recovered in stomach meridian group and gallbladder; meridian group, the metabolic profiling of gastric mocusa tissue in; stomach meridian group are similar to the normal group. The; concentration of methionine, aspartic acid increase and acetic acid,; choline, inositol phosphate, glutamic acid, glycine, lysine, lactic; acid, leucine, isoleucine, taurine, and mannitol decrease in stomach; meridan group (P<0.05). The concentration of 3-hydroxy butyric acid,; methionine increase and choline, inositol phosphate, lactic acid,; leucine, isoleucine, glutamic acid, ethanol amine and mannitol decrease; in gallbladder meridian group (P<0.05). Conclusion: The electropuncture; of acupoints on the foot Yangming stomach meridian could regulate the; metabolic profiling of gastric mucosa, resulting in improving the; gastric mucosa repair of gastric ulcer rats.
