Description

Traditional Chinese medicine composition for treating angina pectoris complicated with hypertension and preparation method thereof

Technical Field

The invention relates to the technical field of traditional Chinese medicines, in particular to a traditional Chinese medicine composition for treating angina pectoris complicated with hypertension and a preparation method thereof.

Background

Because the development speed of the modern society is fast, the rhythm of work, study and life is accelerated, the competition in all aspects is stronger, and the incidence rate of angina pectoris combined with hypertension is increased. Coronary atherosclerotic heart disease refers to heart disease caused by stenosis or obstruction of blood vessel cavity due to coronary atherosclerosis, or myocardial ischemia and anoxia or necrosis due to coronary artery functional change spasm, and is called coronary heart disease for short. Angina pectoris is a kind of coronary heart disease, and is a clinical syndrome with paroxysmal chest pain as main symptom caused by myocardial ischemia and anoxia. Hypertension is characterized by the rise of systemic arterial pressure, is the first risk factor of cardiovascular and cerebrovascular diseases, and the hemodynamic changes caused by continuously rising blood pressure can activate blood platelets in blood, promote coronary atherosclerotic lesions, and cause angina pectoris caused by myocardial ischemia and anoxia. The knowing rate, the control rate and the treatment rate of the hypertension are low in China, the disability rate and the fatality rate are high, and the prevention and control situation is severe. The change of the heart structure and function caused by the increase of the systemic arterial pressure of a patient and the poor control of hypertension for a long time is called as hypertensive heart disease, and the heart failure finally occurs after the myocardial contractile function declines gradually. There are studies showing that 70% of heart failure is caused by hypertension, with angina pectoris complicated by hypertension being the chief culprit.

According to traditional Chinese medicine, angina pectoris is combined with chest stuffiness and vertigo caused by hypertension. Angina pectoris is the chest stuffiness and pain. The disease name is the earliest one in Huangdi's inner classic, which says "lung is big and more fluid, good at chest bi-syndrome". It is a disease with abundant phlegm-dampness and easy to cause obstruction of qi in the chest. Hypertension belongs to the category of vertigo. Vertigo is recorded in the interior (classic) as in the plain questions and the essential essentials: wind-cold syndrome all belongs to the liver. It is pointed out that vertigo is closely related to the liver. Zhang Zhongjing, Shang Han Lun, describes vertigo as "dizzy", "dizzy" and so on, but he proposes the theory of "dizzy due to phlegm". Yu and Yu (Yi Zong Zheng Xue, vertigo) indicates that it is indicated that the syndrome of dizziness caused by fat white in the human body should be treated with the action of clearing phlegm and purging fire first and tonifying qi; for people who are black, thin and dizzy, they are indicated for nourishing yin to reduce fire and with liver-suppressing agent. Points out the key of eliminating dampness and eliminating phlegm in the treatment of vertigo.

The human body is happy to eat the food, is fat, sweet and thick, can damage the spleen and the stomach, enables the spleen to lose health and transportation, transport and transform water-dampness dysfunction, gathers dampness to form phlegm, phlegm retention pathogen can not be found everywhere, goes up to the heart and the chest, obstructs heart vessels to cause chest stuffiness and pains, and remains in the head to cause dizziness; stagnation of qi activity, retention of turbid phlegm, stagnation of phlegm and blood stasis, obstruction of heart vessels to cause chest distress and palpitation, obstruction of clear orifices and blood to cause vertigo; the chest stuffiness, the unsmooth pulse channel and the head blood supply obstacle are caused by qi impairment due to food fullness, weakness of qi circulation and unsmooth qi and blood circulation, so that vertigo is caused; in cold weather, phlegm-dampness and blood stasis are combined, blood congeals when meeting cold, and obstruction of blood vessels causes chest distress and vertigo. The simultaneous treatment of different diseases is the characteristic of the traditional Chinese medicine for treating diseases, and in the aspect of pathogenesis, phlegm, dampness and stasis are used as pathological products and pathogenic factors, and the three are causal to each other and are the main causes of angina pectoris and hypertension. Therefore, the key to treat diseases is eliminating phlegm dampness, promoting blood circulation by removing blood stasis, calming the liver and reducing blood pressure.

Although the existing western medicines have more medicines for treating angina and hypertension, if the medicines are taken for a long time, the patients are easy to have side effects of dizziness, headache, accelerated heartbeat, flushing, nephrotoxicity and the like, and the medicine resistance is easy to generate, so that the curative effect is poor. Therefore, the research of the field is focused on finding the medicine with good treatment effect and small toxic and side effect, and the traditional Chinese medicine has unique advantages in treating the diseases, so that the research of the traditional Chinese medicine composition for treating angina pectoris complicated with hypertension is necessary.

First, curative effect experiment

1. Rat model establishment

80 SPF SD rats with half male and female bodies and weight of 180-220 g are taken. 60 of the rats (hermaphrodite halves) were anesthetized with 10% chloral hydrate (0.4mL/100g) by intraperitoneal injection, then fixed on the operating table supine, the abdominal body hair was cut off, sterilized with 5% iodophor, deiodinated with 75% alcohol, and draped. Opening the abdominal cavity along the operation incision of the abdominal midline, carefully and obtusely separating the left renal artery according to aseptic operation, penetrating 3-0 aseptic silk thread, closely and parallelly placing an acupuncture needle with the diameter of 0.25mm and the long axis of the renal artery blood vessel, tightly tying the renal artery and the acupuncture needle by the 3-0 aseptic silk thread, then drawing out the acupuncture needle, and causing a unilateral renal artery stenosis model, wherein the right artery is not tied. The remaining 20 rats (hermaphroditic halves) were operated and threaded only without ligation of the left renal artery, and served as sham controls.

All rats were post-operatively injected with penicillin (40 ten thousand U/d) intraperitoneally for 3 consecutive days to prevent infection. Each group of animals was fed food and water in a standard feeding environment (temperature and humidity ranges 22-26 ℃ and 53-60%, respectively).

After 10 weeks of molding, 60 successfully molded rats are selected, and the sodium pentobarbital is 30 mg/kg^-1The blood pressure of each model rat is measured by a tail sleeve method of a BP-100A full-automatic rat noninvasive blood pressure measuring system after intraperitoneal injection anesthesia, and the blood pressure is used as the blood pressure value of a hypertension model rat before administration. Dividing randomly into 3 groups according to blood pressure value, including model group, captopril group, and Chinese medicinal administration group, wherein each group contains 20 drugs, and each half of male and female. The sham-operated control rats were anesthetized using the same method, and their blood pressures were measured by the tail-cap method as blood pressure values of the sham-operated control rats before administration.

2. Experimental methods

Each group of rats was administered in groups:

sham-operated controls: the stomach was perfused with physiological saline at 1mL/100g body weight;

model group: the stomach was perfused with physiological saline at 1mL/100g body weight;

captopril group: preparing mixed solution by adding 0.2g of captopril and 100mL of physiological saline, and performing intragastric administration according to the weight of 1mL/100 g;

a traditional Chinese medicine administration group: 10g of the powder of example 3 was mixed with 1000mL of physiological saline to prepare a mixture, and the mixture was administered to the stomach at a concentration of 1mL/100g of body weight.

Each group was gavaged 1 time per day for 4 consecutive weeks.

3. Results of the experiment

The results are shown in table 1, and it can be seen from table 1 that the systolic pressure and diastolic pressure of the rats in the group administered with the traditional Chinese medicine are both significantly lower than those in the model group (P <0.05), and the antihypertensive effect is close to that of the captopril group.

200 outpatient angina pectoris patients with hypertension were treated since 2010. Wherein 100 cases of male and 100 cases of female are 30-70 years old, and the average age is 61 years old; the disease course is 1.5-10 years, 82 cases with the disease course less than 2 years, 67 cases with the disease course less than 2-6 years, and 51 cases with the disease course less than 6-10 years.

1.2 diagnostic criteria

Refer to the standard of treating thoracic obstruction (angina pectoris) and vertigo (hypertension) in "clinical practice and treatment guide & cardiovascular branch book".

1.2.1 Chinese medicine diagnostic Standard

Chest distress can cause suffocation and pain, or pain induced to shoulder and back, shortness of breath, dyspnea, obesity, excessive phlegm, vertigo, headache, head wrapping, chest distress, vomiting phlegm and saliva. A greasy or slippery coating on the tongue and a slippery pulse.

1.2.2 Western diagnostic standards

Angina pectoris diagnosis standard:

stable angina pectoris: is characterized by transient chest pain attacks induced by exercise or other conditions that increase myocardial oxygen demand, often followed by rapid relief after resting or sublingual nitroglycerin intake.

② unstable angina pectoris: is characterized in that the chest pain attack has no obvious relation with the increase of myocardial oxygen demand, and compared with stable angina pectoris, the pain generally has longer duration and heavier degree and is not easy to be relieved by nitroglycerin. The pattern is not changed by enzyme, and the electrocardiogram usually has temporary S-T section depression change.

Diagnosis standard of hypertension: in the case of no antihypertensive drug, the systolic pressure is not less than 140mmHg and/or diastolic pressure is not less than 90mmHg, which are measured 3 times on different days, and hypertension can be diagnosed.

1.2.3 grading Standard of chest pain severity

The method is mild: typical angina pectoris attacks, each lasting minutes, pain attacks at least 2-3 times per week or 1-3 times per day, but the pain is not severe and sometimes nitroglycerin is needed;

moderate degree: typical angina pectoris attacks are carried out for several times every day, the pain lasts for several minutes to about 10min each time, and nitroglycerin is generally needed to be taken;

③ the degree of gravity: the typical angina pectoris attacks many times every day, so that daily life (such as defecation and dressing) is influenced, the duration of each attack is long, and the nitroglycerin needs to be sucked many times.

1.2.4 dizziness grading standard

The method is mild: dizziness, which is stopped when the patient feels dizzy;

moderate degree: the visual object rotates and can not walk;

③ the degree of gravity: vertigo, fainting and incapability of standing.

1.2.5 case inclusion criteria

Has main symptoms of thoracic obstruction and vertigo, is definitely diagnosed, and accords with the western medicine diagnosis standard and the traditional Chinese medicine syndrome of angina pectoris complicated with hypertension with phlegm stagnation and obstruction as well as liver depression and dampness obstruction.

1.2.6 exclusion criteria

The first one is proved by various examinations to be patients with myocardial infarction or other heart diseases, intractable hypertension, severe neurosis, and vertigo caused by brain and neck diseases.

② patients with hypertension of more than moderate degree, severe heart and lung insufficiency, serious primary diseases of liver, kidney and hemopoietic system and psychonoses.

③ those under 18 years old or pregnant women who are allergic to the medicine.

Fourthly, the medicine does not meet the inclusion standard, the curative effect cannot be judged if the medicine is not taken according to the regulation, or the data is not complete, and the curative effect or the safety judgment is influenced.

Exclude other heart diseases complicated with hypertension.

2. Patient grouping and treatment method

Dividing the patients into a treatment group and a control group; all anti-angina drugs are not taken in two groups of patients 2 weeks before treatment, and nitroglycerin tablets can be taken when angina attacks.

Treatment groups: after 2 weeks, the capsules provided in example 3 of the present invention were taken 2-3 capsules/time, 1-3 times/day.

Control group: orally administering DIOXINXUEKANG soft capsule (Chengdu DIOXIKANG group, Inc.) 2 granules/time (3 times/day) after 2 weeks; tablet for refreshing brain and lowering blood pressure (sunflower pharmaceutical group, Bio-pharmaceuticals, Ltd.) is administered at a dose of 5 pills/time, 3 times/day.
