Abstract
The invention relates to application of ginsenoside Re in preparation of a medicine for treating or preventing abdominal aortic aneurysm.
Description
Technical Field
The invention belongs to the field of medicines, and particularly relates to application of ginsenoside Re in preparation of a medicine for treating or preventing abdominal aortic aneurysm.
Background
Abdominal Aortic Aneurysm (AAA) is a serious cardiovascular disease, manifested as degenerative disease in which the abdominal aortic wall structure is destroyed, thereby progressively expanding into a pulsatile mass with a diameter exceeding 1.5 times the normal diameter, with a mortality rate of up to 80% once the tumor mass has ruptured. The main disease population of abdominal aortic aneurysm is the elderly patients, the incidence rate of which is 5 times that of women in men and up to 8% in men over 65 years old, which is a significant cause of death in elderly men. The abdominal aortic aneurysm is caused by inflammation on the wall of the artery, and the infiltration of inflammatory cells causes the transformation of vascular smooth muscle cells from a contraction phenotype to an inflammation phenotype, and stimulates protease-mediated extracellular matrix degradation to cause the apoptosis of the vascular smooth muscle cells and the remodeling of the artery wall, so that the arterial vessel wall is gradually expanded to form the aneurysm. The current inspection technology can find early abdominal aortic aneurysm, but the treatment of the abdominal aortic aneurysm lacks effective therapeutic drugs. For patients with aneurysms that do not meet the surgical requirements (diameter < 5.5 cm and growth rate is not rapid), there is no effective treatment other than close monitoring of the aneurysm diameter.
Panax notoginseng is the dried root and rhizome of Panax notoginseng (Burk.) F.H. Chen of Araliaceae, and the traditional medicine considers that Panax notoginseng saponins have the functions of promoting blood circulation, removing blood stasis, dredging collaterals and activating collaterals, are widely used for treating cardiovascular and cerebrovascular diseases, are important medicinal resources in China, and are also approved by Wei Ji to be articles for health food. The saponin is active component of Notoginseng radix or rhizome, and mainly contains Notoginseng radix saponin R1, ginsenoside Rgl, ginsenoside Re, ginsenoside Rb1, ginsenoside Rd, etc. Wherein ginsenoside Re is used as a main effective component in Notoginseng radix total saponin, and has protective effect on myocardial ischemia, myocardial apoptosis and arrhythmia.
At present, no relevant report is found for the application of ginsenoside Re in treating and preventing abdominal aortic aneurysm.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail and fully with reference to the following embodiments.
Example 1 study of drug efficacy in inhibiting abdominal aortic aneurysm
1. Establishment of abdominal aortic aneurysm model
Experimental animals C57B/6J mice, 12 weeks, SPF grade, male, 20 g in body mass, purchased from the center of Experimental animals at Hebei university of medicine.
The mice are raised in an SPF animal house, and the humidity is kept between 50 and 60 percent and the temperature is kept between 22 and 24 ℃. The illumination period is 7:00-19:00 illumination and 19:00-7:00 darkness. Under sterile environment, anesthetizing 10% chloral hydrate under abdominal skin of mouse, disinfecting abdominal skin by conventional skin preparation, cutting iliac crest at two sides with ophthalmologic scissors, making a 1.5cm incision towards head side, cutting peritoneum deeply, widening visual field, exposing abdominal aorta, separating two sides of artery carefully, stripping off abdominal aorta at iliac artery and renal artery branch, placing cut waterproof film under abdominal aorta, placing small water-absorbing material above the film, slightly smaller than the waterproof film, placing the water-absorbing material in 0.5mol/L CaCl2Wrapping and externally applying, taking out the water absorbing material, the waterproof film and the sterile gauze in sequence after 15min, sucking the residual liquid, flushing the abdominal cavity with sterile normal saline, and ligating bleeding points. And (4) performing surgical suture, respectively suturing the peritoneal layer and the skin layer, and placing the anesthetized mouse in a lateral lying position. After operation, 7 days later, the heart apex of the mouse is perfused, the abdominal aorta is taken, the diameter of the abdominal aorta at the lower end of the kidney is measured, and the abdominal aortic aneurysm modeling is successful after 50% of amplification compared with the diameter of the abdominal aorta at the lower end of the kidney of the blank control group of mice.
2. Treatment regimens
The mice were divided into three groups, 5 model control groups, 5 ginsenoside Re groups, and 5 blank control groups. The model control group and the experimental group are respectively molded according to the method, and after operation, the model control group is perfused with the normal saline, the administration dosage of the experimental group is 50 mg/kg/day, and the treatment lasts for 14 days. And (3) perfusing the apex of the heart of the mouse, taking the abdominal aorta, measuring the diameter of the abdominal aorta at the lower end of the kidney, and respectively recording the diameters of the abdominal aorta under the kidney of the mouse in a blank control group, a model control group and an experimental group. The average value of the blank control group is used as a standard value 1.
3. Results
