Application of ginsenoside Re in preparing medicine for preventing or treating cholestatic liver diseases
Technical Field
The invention relates to the technical field of traditional Chinese medicines, in particular to application of ginsenoside Re in preparation of a medicine for preventing or treating cholestatic liver diseases.
Background
Cholestasis is a phenomenon in which bile acid accumulates in a large amount in hepatocytes and bile ducts due to formation and distribution of bile in the body. Cholestasis can lead to the occurrence of cholestatic liver disease. Cholestatic liver disease occurs because of complex causes, and viral infection, drugs, pregnancy, immunity, genetics, parenteral nutrition, etc. can cause intrahepatic cholestasis, such as less effective treatment, and may even progress to liver fibrosis, cirrhosis, liver failure, and liver tumors. Epidemiological evidence shows that the incidence rate of cholestatic hepatitis in China accounts for more than 10% of patients with chronic liver diseases. The incidence rate of cholestatic hepatitis in China accounts for more than 10% of patients with chronic liver diseases. Currently, the main clinical therapeutic drugs include ursodeoxycholic acid (UDCA), S-adenosylmethionine, cholestyramine, obeticholic acid, fibrates, etc., wherein UDCA is a first-line drug clinically recommended, and the main purpose is to improve clinical symptoms and liver injury caused by cholestasis. However, clinical efficacy is not yet satisfactory, about 30% of patients are ineffective against UDCA, and UDCA has slow onset, is more expensive, and is in urgent clinical demand for more effective drugs.
Ginsenoside Re (G-Re) is tetracyclic triterpene extracted from Notoginseng radix and Ginseng radix. At present, research reports that ginsenoside Re can relieve oxidative stress by up-regulating GPX4, so that 6-hydroxydopamine induced cell injury is relieved. Ginsenoside Re can also relieve LPS-induced systemic inflammation by inhibiting TLR4 pathway. Furthermore, ginsenoside Re has also been reported to reduce myocardial apoptosis following ischemia reperfusion by affecting Bcl-2 and Bax levels. In addition, ginsenoside Re can also regulate autophagy, inhibit JNK and NF- κB activation, and thereby reduce insulin. The ginsenoside Re has various biological activities such as anti-inflammatory, antioxidant and anti-apoptosis, and has remarkable effects in treating diabetes and cardiovascular diseases.
However, the therapeutic effect and mechanism of ginsenoside Re on cholestatic liver diseases have not been reported yet.
