艾灸肝脏效应及其影响因素的实验研究进展

Through retrieving the relevant experimental researches from Pubmed, CNKI, Wanfang and VIP databases, it is discovered that the effects of moxibustion on liver are mainly reflected in the following three aspects, namely, maintaining the normal functions of liver, promoting the repair of liver injury and delaying liver aging. By further analysis and in view of experiments, the factors influencing these effects may include stimulation site, stimulation intensity and heat source. The effects of moxibustion on liver and its influencing factors are explored and discovered in the perspective of experimental researches and these discoveries have been verified in clinical practice correspondingly. Based on the current study situation, moxibustion therapy is still limited in clinical studies on liver disorders as compared with the experimental researches. Hence, the deep exploration of moxibustion on its specific biological effect and mechanism and the excavation of moxibustion on its clinical application are likely to be the coming emphasis of the basic research and clinical practice for moxibustion.     

45℃艾灸“足三里”改善高脂血症大鼠血管内皮的氧化应激

目的:探究艾灸改善血管内皮功能的抗氧化效应机制。方法:将40只雄性SD大鼠随机分为空白组、模型组、艾灸组和eNOS抑制剂组，每组10只。采用高脂饲料喂养8周制备高脂血症大鼠模型。艾灸组予45℃艾灸“足三里”干预，10 min/次，eNOS抑制剂组在艾灸干预的同时予腹腔注射eNOS抑制剂，均1次/d,连续干预4周。采用HE染色法观察大鼠腹主动脉血管内皮形态；油红O脂肪染色法检测各组大鼠腹主动脉脂肪沉积情况；ELISA法检测血清及腹主动脉中血管活性物质及氧化应激相关指标水平；免疫荧光法检测大鼠腹主动脉中内皮型一氧化氮合酶(eNOS)的表达。结果:空白组腹主动脉呈粉红色，细胞核及血管周围组织结构清晰，血管内皮层光滑，血管内膜、中膜及外膜层纹理清晰；模型组腹主动脉呈暗粉色，颜色较淡，血管内皮层毛糙，血管内膜、中膜及外膜层纹理粗糙；艾灸组腹主动脉呈粉红色，细胞核及周围组织结构清晰，血管壁光滑；eNOS抑制剂组腹主动脉呈暗粉色，颜色较淡，纹理较粗糙。与空白组比较，模型组腹主动脉油红O染色面积比增大(P<0.05);血清总胆固醇(TC)、甘油三酯(TG)、低密度脂蛋白胆固醇(LDL-C)含量升...
