It also analyzes the therapy path for acupointapplication on the treatment of chest obstruction heartache taking "acupuncturepoints" and "meridians" from meridian theory as the breakthrough point. The papermines the ancient literature of "Fifty-Two Diseases”,“Medical Origins" and"Theory of Parallel Prose” and traces the historical origins of acupointapplication therapy for coronary heart disease (CHD) and then combines classicalresults of the literature with modern pharmacological research to illustratethat the supervisor’s angina pectoris patch prescription basis and acupointsposition.Conclusion:With the foundational theories of TCM and meridian, the paper proves that the"angina pectoris patch" acupoint application can be used to treat coronary heartdisease (CHD). PART II–Discussion on "angina pectoris patch" acupoint applicationpretreatment on acute myocardial infarction rats and the influence of mechanismObjectives:To discuss the intervention effect of “angina pectoris patch” on acutemyocardial infarction and explore the intervention mechanism of “anginapectoris patch” on acute myocardial infarction from the perspectives of nitricoxide system adjustment and calcium sensitive receptor inhibition, which arebased on the observation of influence of “angina pectoris patch” acupointapplication pretreatment on acute myocardial infarction in the rat myocardialcell morphology, electrocardiogram and myocardial enzymology.Methods:55healthy wistar rats were randomly divided into normal group, model group,control group and treatment group, with10in normal group, and15in each ofthe model group, control group and treatment group. In clean grade laboratory,feeding with ordinary fodder for7days, the control group were given withNitroglycerin Plaster to0.3mg on the area before the heart, each time1stick,1times a day, keep24hours at a time, a total of seven days. Treatment groupwere given angina pectoris patch acupoint application, each patch0.1g, onceper day lasting for24hours, one patch per acupoint,1time per day and7daysin total. Medical modeling started on the4thday causing the model group, controlgroup and treatment group of animals to be acute myocardial infarction animalmodels with the specific method as follows. Between the5thday and the7thday,applying immediately after injection of animals in model group, control groupand treatment group isopropyl adrenaline, adopt the method of multi-pointsubcutaneous injection, isopropyl dosage of epinephrine is5mg/kg, afterepinephrine injection for7days, each live animals with chloral hydrateanesthesia subcutaneously dose (mg/kg), anesthesia after a successful checkelectrocardiogram (ecg), ST segment obvious up or down for building successfulpreliminary judgment standard, abdominal aorta to groups of animals blood, take heart. Lens under the observation of the myocardial pathology morphology andmyocardial ultrastructure were observed under electron microscope. Fullyautomatic biochemical instrument enzymatic detection of Creatine kinaseisoenzyme (CK-MB), Lactate Dehydrogenase (LDH). Immunohistochemical methodtest Malondialdehyde (MDA), Superoxide Dismutase (SOD), Tumor Necrosis factor(TNF-alpha), Interleukin-6(IL-6), B cell lymphoma/leukemia-2B (Bcl-2),Bax, cysteine, aspartic acid proteinase3(Caspase-3), Substance P (SP),endothelial nitric oxide synthase (eNOS), induced nitric oxide synthase (iNOS)sensitive receptors, calcium (CaSR).Fluorescence quantitative PCR method typeeNOS, iNOS, CaSR.Results:Observed under optical microscope and electron microscope, myocardial cell ofnormal group shows normalshape. Model group myocyte necrosis, interwoven intoa network, horizontal stripes disappear, myocardial cell nucleus and visiblemuscle fibers arranged disorder, fault and loss, myocardial cell nucleuspycnosis, appear blank area, heterochromatin appears crumb, broadeningintercalated disc gap adjacent cells. Necrosis of myocardial cell damage in thecontrol group and treatment group compared with model group, but also a smallfracture and defect and uneven coloring appear blank area. Under the transmissionelectron microscopy (sem): normal group of myocardial cell no change. Myocardialmitochondrial injury model group, double membrane structure is not clear, crestfracture, most are vacuolated, partly dissolved; The nucleus chromatinconcentrated and part of the cytoplasm dissolved and disappeared, and showsliquefactive necrosis; Myofibril extremely flabby, vacuoles, some fracture,myofilament intercalated disc local expansion, structure is not clear, dissolved.Light in the control group and treatment group of mitochondrial damage and doublemembrane structure is clear, part of the crest fracture, the nucleus structurebasic integrity, myofibril arranged neatly, visible myofilament fracture. Model group, western medicine control group and Chinese medicine treatment groupthe absolute value of st-segment up or down significantly higher than normalgroup (P <0.01). Western medicine control group and traditional Chinese medicine(TCM) the absolute value of st-segment up or move down in treatment group werelower than model group, with statistical significance (P <0.01), Chinesemedicine treatment group compared with the western medicine control group,without statistical significance.Control group and treatment group CK level was lower than those of model group,compared with model group, with statistical significance (P <0.01). CK-MBin the control group, treatment group was lower than those of model group,compared with model group, with statistical significance (P <0.05, P <0.01);Level of CK and CK-MB in treatment group compared with control group, withoutstatistical significance. Groups of LDH level comparison, there were nostatistical significance (P>0.05).immunohistochemical results: model group MDA, TNF-α,IL-6, substance P,caspase3, Bax is high in the normal group (P <0.05). the treatment group TNF-α, substance P, caspase3, Bax was lower than those of control group (P <0.05).Model group, control group, treatment group, SOD, the BCL-2was lower thanthose of normal group, the SOD, the Bcl-2higher than the control group, treatmentgroup (P <0.05).ENOS, iNOS,CaSR immunohistochemical results and fluorescent quantitative PCRresults: model group, control group, treatment group of iNOS higher than normalgroup,(P <0.05). The control group, treatment group of iNOS was lower thanthose of model group (P <0.05). INOS treatment group than the control group,2group, with statistical significance (P <0.05). Model group, control group,treatment group of eNOS was lower than those of normal group (P <0.05). ENOSin control group, treatment group compared with model group (P <0.05); ENOStreatment group was lower than those of control group, the comparison of two groups, there is statistical significance (P <0.05).model group, control groupand treatment group CaSR higher than normal group, with statistical significance(P <0.05). CaSR in control group, treatment group was lower than those of modelgroup (P <0.05); CaSR treatment group was lower than those of control group,the comparison of two groups, there is statistical significance (P <0.05).Conclusion:1angina patch of acupoint sticking pretreatment can reduce AMI necrosis ofmyocardial damage degree, its effect and the effect of nitroglycerin patchattached with pretreatment, the specific intervention mechanism related to thefollowing four aspects: by inhibiting lipid peroxidation, promoting SODgenerated, reduce the MDA; Suppress TNF alpha, IL-6, have anti-inflammatoryeffects; Inhibition of CaSR reduce calcium overload; Increase the expressionof eNOS, cut the expression of iNOS.2angina pectoris patch in regulating NOS aspects effect is not good asNitroglycerin Plaster, in inhibiting peroxidation damage, anti-inflammatory,inhibiting calcium overload effect superior to Nitroglycerin Plaster.3angina pectoris patch acupoint pretreatment may inhibit myocardial cellapoptosis after AMI. The mechanism is inhibited casepase3, promoting bcl-2expression and inhibit the expression of Bax and inhibition of CaSR.4anginapectoris patch has analgesic action, its mechanism may be related to inhibitingsubstance P.PART III-Clinical Curative Effect Observation of "angina pectoris patch"acupoint application therapy in treatment of both Qi deficiency and blood stasissyndrome of coronary heart disease (CHD) unstable angina pectorisObjective:To observe the clinical treatment effect of “angina pectoris patch” on coronaryheart disease (CHD) unstable angina patients with Qi deficiency and blood stasis. Methods:60patients of Qi deficiency and blood stasis syndrome of coronary heart diseaseunstable angina patients, according to random number table method, were randomlydivided into treatment group and control group, with30patients in each group.Control group were given conventional western medicine treatment and thetreatment group, were given "angina pectoris patch" acupoint applicationtreatment for10days, on the basis of the conventional western medicinetreatment. Angina pectoris attack frequency, duration, numbers of pains and TCMsymptoms such as chest pain, chest tightness, palpitations, shortness of breath,fatigue, constipation.Results:Angina pectoris symptoms, Chinese medicine treatment group effective comparedwith control group, was statistical significant (P <0.05). Attack frequencyof angina pectoris, pain degree of curative effect of treatment group weresuperior to control group (P=0.005, P=0.006); Chest pain, shortness of breath,fatigue effect of treatment group were superior to control group (P=0.028,P=0.000, P=0.010).Conclusion:On the basis of conventional western medicine treatment, angina pectoris patch,can ease the qi deficiency blood stasis type of angina, unstable angina patientsimprove TCM symptoms, especially to attack frequency of angina pectoris, andthe degree of pain, chest pain, shortness of breath, fatigue has obvious effect.
