Description

Composition for treating type 2 diabetes and preparation method and application thereof
Technical Field
The invention belongs to the technical field of diabetes medicine research, and particularly relates to a composition for treating type 2 diabetes, a preparation method and application thereof.
Background
"diabetes" is a disease in which glucose in blood tends to accumulate too much. Epidemiological investigation report in 2019 shows that the number of diabetics in China is 1.164 hundred million, and with the increasing population aging, the probability of suffering from diabetes rises year by year, wherein 60% -80% of diabetics are obese people before the onset of the disease, have poor constitution and need to be controlled by taking medicine for a long time. It is predicted that during 1995-2025, the incidence of diabetes in developed countries abroad will break through 27%. Diabetes has become an epidemic worldwide in the 21 st century. The traditional Chinese medicine is a chronic non-infectious disease which is the third most serious threat to human health after tumor and vascular lesions, has the characteristics of high mortality rate, high disability rate and high medical cost, and becomes a public health problem commonly faced by countries in the world. Diabetes mellitus is a serious situation in China.
China is a large country of traditional Chinese medicine resources and has a long history of treating diabetes by traditional Chinese medicines, so that the development of traditional Chinese medicine preparations for effectively treating diabetes is a wish of many pharmaceutical workers. In recent years, it has also been proved that various compounds having pharmacological activity can be extracted and isolated from natural medicines. The action mechanism of the traditional Chinese medicine composition on diabetes and complications thereof has been discussed by students at home and abroad from various angles. Proved by researches, baicalin is an effective Aldose Reductase (AR) inhibitor, and can obviously reduce the AR activity of kidney rats with kidney diseases; quercetin also has certain inhibition effect on AR; the extract of radix Sophorae Flavescentis mainly contains isoflavone, and can prevent cataract of diabetic patient by inhibiting activity of key enzyme AR in glucose metabolism; guava She Mugan can enhance capillary permeability of diabetics. Because the flavonoid compounds in the natural plants or the medicaments have low toxicity, not only can reduce blood sugar, but also can inhibit the development of complications, the development of the medicament sources is very important at home and abroad, and new effective components are extracted. However, most of the pharmacological actions of flavonoids against diabetes and complications thereof are still in the experimental stage, and only a small part of the clinical trials are entered. Some of the other traditional Chinese medicine components act similarly to alpha-glucosidase inhibitors. For example, foreign studies have found that a variety of polyhydroxy alkaloids are present in Morus plants, and that some polyhydroxy alkaloids isolated from Morus alba, mori folium and Mori fructus have good glycosidase inhibitory activity; the researchers in China also successfully extract alkaloids (mainly 1-deoxynojirimycin) with similar effects from tender mulberry twigs and silkworm excrement. It is pleasant that the Chinese medicine insulin sensitizer which is independently developed in China is about to enter clinical research. Experts generally consider that developing a new way for treating diabetes by using traditional Chinese medicines and ethnic medicines with clear effective parts, clear mechanism and definite curative effect is an important task to be solved urgently by medical workers. Western medicines such as dapagliflozin, metformin, sitagliptin and the like are combined with insulin to be used in combination mainly in foreign countries. In recent years, with the deep application research of traditional Chinese medicines for treating diabetes, a plurality of traditional Chinese medicines and compound preparations thereof show good curative effects. The Chinese medicinal preparations of Xiaokeling tablet, kelening tablet, jinqi Jiangtang tablet, yuye Xiaokejie granule, yangyangjiang Jiapian, jiangtangsu capsule, xiaokejiangjiang tablet, jiangtangjiao capsule, xiaokejiangjiang capsule, xiaokejiangjiangjiang capsule, xiaokewan and the like are accepted by the pharmacopoeia of people's republic of China and the ministry of force standard. The traditional Chinese medicine has the characteristics of single effect, can reduce blood sugar, improve insulin secretion in vivo and prevent and treat diabetic complications. Therefore, developing an innovative traditional Chinese medicine preparation with good curative effect, convenient administration and safe use is an urgent need of drug researchers.
