Abstract

The invention discloses application of CST polypeptide in preparation of a medicine for treating femoral head necrosis, particularly application in preparation of a medicine for treating hormone-induced femoral head necrosis, and particularly application in preparation of a medicine for relieving hormone-induced femoral head necrosis collapse. The functional polypeptide CST plays a protective role in femoral head necrosis. In-vitro cell experiments show that CST can antagonize an osteoblast apoptosis process caused by glucocorticoid. Meanwhile, an animal model shows that CST can inhibit femoral head necrosis collapse and improve the illness state, has no obvious toxic or side effect after long-term application, can be used in the fields of femoral head necrosis and the like, and has wide application value and market prospect.

Description

technical field [0001] The invention relates to the field of medicine, in particular to the application of CST polypeptide in the preparation of drugs for the treatment of femoral head necrosis. Background technique [0002] At present, necrosis of the femoral head is more common clinically, and it tends to be younger at present. According to statistics, in my country alone, there are more than 5 million patients with femoral head necrosis. At present, there is no specific drug for osteonecrosis of the femoral head, and the clinically applied drugs are not effective. If the patient's condition is severe, hip joint surgery, heart medullary decompression or hip joint replacement surgery is required[1]. However, the surgery itself has associated risks and complications, and has its own limiting factors. With the increasing number of patients, the treatment of femoral head necrosis has caused a huge burden on society and families. [0003] At present, most of the therapeutic ...
