Embodiment 1

[0228] Induction of AIA

[0229] The AIA model was induced on day 0 by a single subcutaneous injection of 0.1 ml of a freshly prepared suspension containing 62.5 μg of Mycobacterium tuberculosis (MT) H37Ra (BD, Sparks, USA) into the tail of the animal. Rats in the control group were injected with an equal volume of normal saline instead of MT suspension. In the experiment lasting 42 days, AIA rats (n=10-12) were given 100, 200 mg / kg of silibinin (20% PEG400: 15% Cremophor EL: 5% ethanol: 60% saline solution) every day , or oral administration of 7.6 mg / kg MTX or blank solvent (20% PEG400: 15% Cremophor EL: 5% ethanol: 60% saline).

[0230] Assess the severity of arthritis and the effect of silibinin treatment

[0231] Disease severity and progression were assessed by measuring the volume and body weight of both hindpaws with a plethysmograph and a precision balance every two or three days after induction of arthritis. In order to accurately assess the arthritis score, each ...

Embodiment 2

[0302] MCD diet-induced mouse NASH model

[0303] Male wild-type C57Bl / 6 mice were fed with normal diet MCS (China Nutrition Animal Feed High-Tech Co., Ltd., China, #TP 3005GS) and MCD (China Nutrition Animal Feed High-Tech Co., Ltd., #TP3005G) for 8 weeks. Tables 15 and 16 give the compositions of the feeds, respectively. The animals were randomly divided into four groups (n=10): 1) the control group, fed with MCS feed; 2) fed with high-fat MCD feed; 3) fed with MCD feed and administered 150 mg / kg silibinin orally; 4) fed with MCD Feed and orally administered 300mg / kg silibinin. Silybin was dissolved in 35% PEG400: 15% Cremophor EL: 5% ethanol: 45% saline. Body weights were measured every two or three days during induction and during intervention.

[0304] At the end of the 8th week, the mice were sacrificed by ether anesthesia. The livers were immediately removed and weighed. Most of the livers were quickly frozen in liquid nitrogen, and the rest were fixed in 10% formal...

Abstract

A method for reducing abnormalities in lipid metabolism and for reducing inflammation in a subject suffering from an autoimmune inflammatory disease accompanied by abnormalities in lipid metabolism includes administering an effective amount of a flavonolignan to the subject. The subject may additionally suffer from a liver disease, obesity, hypertension, diabetes mellitus or a metabolic syndrome.Further provided is a method for reducing the risk of a cardiovascular disease in a subject suffering from an autoimmune inflammatory disease accompanied by abnormalities in lipid metabolism and a method for reducing hepatic abnormalities and reducing inflammation in a subject suffering from an autoimmune inflammatory disease accompanied by hepatic abnormalities. Still further provided is a methodfor reducing liver damages associated with the treatment of rheumatoid arthritis with a disease-modifying antirheumatic drug or a non-steroidal anti-inflammatory drug.

Description

technical field [0001] The invention relates to the application of flavonoid lignans in the preparation of drugs for reducing abnormal lipid metabolism and inflammation of subjects. The subject is a mammal, such as a human, and suffers from an autoimmune inflammatory disease, specifically autoimmune arthritis, preferably (but not limited to) rheumatoid arthritis, with abnormal lipid metabolism. Abnormalities in lipid metabolism may specifically be reduced HDL cholesterol levels, normal or slightly increased total cholesterol levels, normal or slightly increased LDL cholesterol levels, normal or slightly increased triglyceride levels, and optionally further With liver abnormalities. The flavonoid lignans of the present invention can be used in subjects suffering from liver disease, metabolic syndrome, obesity, diabetes or hypertension. Also provided is the application of flavonoid lignans in the preparation of a drug for reducing the risk of cardiovascular disease in a subjec...
