Abstract:

BACKGROUND: As one of the main active ingredients in epimedium, icariin plays an important role in bone defect repair. Sustained and effective concentration of icariin in vivo is essential for bone damage repair.
OBJECTIVE: To recommend the research progress of epimedium glycoside for bone repair and to explore the pharmaco-active concentration of icariin.
METHODS: A computer-based online search of CNKI database (http://www.cnki.net/) and PubMed database (http://www.ncbi.nlm.nih.gov/PubMed) from January 2000 to October 2013 was performed for related articles of the effect of icariin for bone defect repair and bone damage repair. The key words were “icariin, concentration, bone” in Chinese and English. After repeated articles were excluded, 76 related articles were screened out and 44 of them met the inclusive criteria.
RESULTS AND CONCLUSION: The icariin-released scaffold materials can induce the osteogenic differentiation of bone marrow-derived mesenchymal stem cells, promote the viability of osteoblasts and inhibit the resorption of  
osteoclasts, thus repairing bone tissue. It is certain that icariin promotes cellular differentiation, however whether it can promote cellular proliferation remains unclear. The pharmaco-active concentration of icariin ranges from10-8 to 10-5 mol/L, but clinical trial has not yet been carried out, and specific drug concentration is uncertain, which needs further exploration.
