【摘要】：目的心血管疾病是當今威脅人類健康和生命的主要疾病之一,心肌缺血是心血管疾病的主要因素。針刺用于防治心肌缺血已有數(shù)千年的歷史,具有操作簡便快捷、療效確切的特點,但其作用機制尤其是分子生物學機制目前尚不完全清晰,在一定程度影響了針灸在心肌缺血臨床的應用及推廣。相關(guān)研究表明,在心肌缺血的過程中存在普遍心肌細胞凋亡表現(xiàn),而細胞凋亡是受基因嚴格控制的,其中Micro RNA(miRNA)的調(diào)控具有關(guān)鍵作用。針刺是否是通過miRNA基因調(diào)控途徑干預心肌細胞凋亡?主要是通過什么miRNA基因調(diào)控的?主要的miRNA基因是通過什么信號調(diào)控途徑發(fā)揮作用的?這些都是需用研究的問題。有據(jù)于此,本課題選用心肌缺血模型大鼠為研究對象,在中醫(yī)針灸“治未病”理論為指導下,采用“標本配穴”電針干預方法,以細胞凋亡為切入點,運用miRNA基因芯片篩選、實時熒光定量PCR(q

[Abstract]:Objective cardiovascular disease is one of the major diseases that threaten human health and life today. Myocardial ischemia is the main factor of cardiovascular disease. Acupuncture has been used to prevent and cure myocardial ischemia for thousands of years. It has the characteristics of simple and quick operation and accurate curative effect. But the mechanism of its action, especially the molecular biological mechanism, is not completely clear at present. It has influenced the clinical application and popularization of acupuncture and moxibustion in myocardial ischemia to a certain extent. Related studies have shown that there is a general expression of cardiomyocyte apoptosis in the process of myocardial ischemia, and the apoptosis is strictly controlled by genes, in which the regulation of Micro RNA (miRNA) is the key to be used. Whether acupuncture is the intervention of miRNA gene regulation pathway Cardiomyocyte apoptosis? What is the main miRNA gene regulated by miRNA gene? Are the main miRNA genes play the role of the signaling pathway? These are the problems that need to be studied. Acupoint electroacupuncture intervention method, taking cell apoptosis as the breakthrough point, using miRNA gene chip screening, real-time fluorescence quantitative PCR (Q RT-PCR) and Western blot (Western blot) techniques to observe the influence of apoptosis related miRNA and its target gene expression in cardiac myocyte apoptosis and its regulatory relationship, and explore the miRNA gene of "specimen matching point" acupuncture intervention on myocardial ischemia Regulation mechanism, in order to provide theoretical support and scientific basis for the prevention and treatment of myocardial ischemia by acupuncture. Method 1. 40 SPF male Wistar rats, weighing 180-220g, were randomly divided into normal group, model group, Neiguan electroacupuncture group (Neiguan group), group acupoint electroacupuncture group (marking group), 10 in each group. Model group, Neiguan group, and standard group rats were given the isopropionic kidney. Adenin (ISO) 2mg/ (kg / D) was injected subcutaneously for 14 days. Then BL-420 biological function system was used to detect the electrocardiogram of rats in the model group. QRS wave, QT wave duration extended (QRS0.1s), T wave morphologic change was used as a successful model. The normal group rats were given the same amount of 0.9% raw saline under the abdominal subcutaneous injection for 14 days. Normal group, model group rats The Neiguan group needled bilateral "inner customs" (5 mm in the middle of the wrists in the middle of the rat's wrist and 0.5 cm deep in the needle), and the marking group was puncturing bilateral "inner customs", "Guan yuan" (about 25 mm under the umbilicus of the rat, 0.5 cm in deep acupuncture), bilateral "Zusanli" (the posterior lateral of the knee of the rat, the small head of the fibula about 5mm, and the needling depth about 0.8 cm). Group the same side acupoints composed of a pair of electrodes, Neiguan group and the mark group Neiguan point at the right side of the acupoint on the right side of the acupoint at 0.5cm, another needle as an auxiliary electrode, then HANS LH202H electroacupuncture treatment instrument, continuous wave, 2 Hz, the intensity 1m A, with the limbs of the rats have a feeling of tremor as suitable strength, 1 times a day, a total of 21 days. Rats on the twenty-second day.

Conclusion 1. electroacupuncture can reduce LVEDd, LVESD value, EF, FS value of myocardial ischemia model rats, effectively improve the compensatory cardiac dilatation caused by myocardial ischemia cell apoptosis, heart dysfunction, and reduce myocardial fine. The degree of apoptosis, and the Electroacupuncture of "sample acupoint" electroacupuncture is better than the simple Neiguan electroacupuncture method..2. can change the index of myocardial enzymes caused by myocardial ischemia cell apoptosis. "Specimen acupoint" electroacupuncture and Neiguan electroacupuncture can effectively reduce the activity of CK-MB, VCAM-1 and ET-1 in experimental rats to play anti myocardial deficiency. Blood effect, and the "specimen matching point" electroacupuncture method has a better effect than pure Neiguan electroacupuncture..3. multiple miRNA gene participates in the apoptosis process of myocardial ischemia cells in rats induced by the adrenal gland. During the process of myocardial ischemia, the main manifestations are miRNA-133-3p, miRNA-133-5p, miRNA-1-3p, miRNA-486 rise, and "specimen with acupoint" electricity. The needle method can effectively enhance the expression of miRNA-133-3p and miRNA-133-5p and reduce the expression of miRNA-1-3p and miRNA-486. The protective effect is to inhibit the apoptosis of myocardial cells by controlling these 4 miRNA genes and the target gene is the main way to affect the apoptosis of myocardial ischemia cells. "Specimen matching point" electroacupuncture is used to prevent and cure myocardium. In the miRNA signaling pathway of ischemia, the gene regulation signal between miRNA-133-5p and Caspase-3 and Aifm2 is the main way of activating.5.Caspase-3 and Aifm2 factor, which is the main executive factor to activate the apoptotic pathway. "Specimen matching" electroacupuncture inhibits apoptosis and protects the heart from the function of miRNA-133-5p. Thus, the dual channel regulation of Caspase-3 and Aifm2 expression can be reduced.
