Apoptosis of bone cells in alcohol-induced osteonecrosis of femoral head / 中国组织工程研究

ABSTRACT

BACKGROUND:Currently, there is a lack of effective hip preserving therapy in patients with alcohol-induced osteonecrosis of femoral head. Artificial hip replacement is the only choice for the patients whose function of the hip joint is affected by the colapse of the femoral head in the late stage. Therefore, to understand the pathogenesis of alcohol-induced osteonecrosis of femoral head is of great significance for the effective hip preserving therapy in patients. OBJECTIVE: To review the research progress in apoptosis of bone cels in the pathogenesis of alcohol-induced osteonecrosis of femoral head both at home and abroad in recent years, so as to provide a theoretical basis for the study of the treatment of alcohol-induced osteonecrosis of femoral head. METHODS:PubMed and Embase databases were retrieved by the first author using computer to search relevant articles addressing the effect of apoptosis of bone cells in the pathogenesis of alcohol-induced osteonecrosis of femoral head. The keywords were “osteonecrosis of femoral head and apoptosis”, “bone cell, apoptosis, gene, signal” or “osteonecrosis, alcohol”in the title and the full text. Repetitive and old literatures were excluded, and finally 40 foreign language articles were included in result analysis. RESULTS AND CONCLUSION: In recent years, the theory of apoptosis of bone cells in the pathogenesis of alcohol-induced osteonecrosis of femoral head has been gradually recognized and has become the focus of research on the pathogenesis of alcohol-induced osteonecrosis of femoral head. Apoptosis of bone cells plays an important role in the pathogenesis of alcohol-induced osteonecrosis of femoral head. Various genes, such as p53, Bcl-2 family, tumor necrosis factor, Caspase, are crucial to control the apoptosis of bone cells. Although we have made some progresses at the gene level, there is still a lack of relevant studies on alcohol-induced osteonecrosis of femoral head due to the complexity of pathogenesis.
