Embodiment Construction

[0033] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.

[0034] hBMSC is a human bone marrow mesenchymal stem cell with multi-directional differentiation potential, such as differentiation into osteoblasts, adipocytes, fibroblasts, etc. It is a more commonly used cell model for studying the growth and differentiation of bone marrow mesenchymal stem cells. H 2 o 2 Treatment is also a commonly used in vitro oxidative stress model. In order to observe the effect of saikosaponin a on apoptosis and differentiation of human bone marrow mesenchymal stem cells, and its anti-oxidative damage, hBMSC was selected as the cell model. H 2 o 2 Treated as an in vitro model of oxidative stress. As an animal model, the ovariectomized (castrated) mouse model is commonly used to simulate postmenopausal osteoporosis in women.

Abstract

The invention discloses an application of saikoside a in prevention and treatment of osteoporosis. According to the application of saikoside a in the prevention and treatment of osteoporosis, saikoside a is characterized by being no toxic to human mesenchymal stem cells, not influencing cell proliferation, but preventing human mesenchymal stem cells from apoptosis caused by hydrogen peroxide, improving H2O2 induced oxidative stress state during differentiation, preventing human mesenchymal stem cells from differential inhibition caused by H2O2, inhibiting raising of adipogenic differentiation of human mesenchymal stem cells caused by H2O2, and also inhibiting the expression of bone resorption factors, so as to reduce apoptosis and differential inhibition of human mesenchymal stem cells and indirectly inhibit osteoclast activation to prevent osteoporosis. According to a castrated mice osteoporosis model, saikoside a can improve the oxidative stress of serum and can also improve cancellous bone microstructures of distal femur and the fourth lumbar vertebra; and therefore, saikoside a can be used for preparing a medicine for preventing and treating osteoporosis.

Description

technical field [0001] The invention belongs to the technical field of prevention and treatment of osteoporosis, and relates to the application of saikosaponin a in the prevention and treatment of osteoporosis. Background technique [0002] Osteoporosis (OP) is a systemic, degenerative, metabolic skeletal disease characterized by loss of bone mass, deterioration of bone microarchitecture, and decline in biomechanical properties caused by various etiologies, resulting in increased bone fragility. Fractures are prone to occur, which seriously threatens the physical and mental health of middle-aged and elderly people. [0003] Oxidative stress is a state in which highly active substances such as ROS (Reactive oxygen species) are produced excessively in the body, which exceeds the body's ability to remove them, resulting in an imbalance between oxidation and anti-oxidation. ROS in the physiological range play an important role in regulating normal functions of the human body, s...
