文题释义:
微环境:股骨头微环境是指骨组织细胞周围近距离作用和调控细胞兴奋或抑制活动的微量理化因素,以及骨细胞在增殖和分化过程中形成的特殊结构在骨组织细胞局部组成的机能环境。
Starling原理在股骨头内压力变化中的应用:股骨头是一个坚硬而不能膨胀的骨腔室,增殖肥大的脂肪细胞既可直接压迫血窦,又可使骨内压异常升高,微循环淤滞,加重股骨头缺血,造成恶性循环,导致股骨头缺血性坏死。
 
摘要
背景:酒精性股骨头坏死的发病机制目前尚不明确。
目的:介绍股骨头微环境的生理结构和酒精致股骨头微环境的病理变化,综述酒精对股骨头微环境影响的研究现状。
方法:应用计算机检索1990至2016年中国知网及PubMed数据库关于酒精对股骨头局部微环境影响的临床及实验文献报道,归纳综述酒精性股骨头坏死的病理过程。
结果与结论:酒精性股骨头坏死的发病机制目前有多种学说,但其本质均为股骨头骨组织的血液循环障碍,骨的营养物质和氧供减少,骨组织、细胞长期缺氧而发生变性、坏死。大剂量酒精摄入可引起氧化-抗氧化系统失衡,严重影响股骨头局部血运环境。氧环境改变加速股骨头坏死,骨髓间充质干细胞成骨分化能力减弱,骨吸收与骨形成的平衡遭到破坏,最终加剧股骨头的坏死与骨结构塌陷。通过调控股骨头微环境的改变有望为延缓或阻止早期股骨头坏死病变进程提供新的治疗策略。

Abstract:

BACKGROUND: The pathogenesis of alcoholic avascular necrosis remains unclear.

OBJECTIVE: To introduce the physiological structure and pathologic changes induced by alcohol of the microenvironment of femoral head, and to review the research status of the influence of alcohol on the microenvironment of femoral head.
METHODS: A computer-based online research of PubMed database for clinical and basic studyies concerning the effect alcohol on the microenvironment of femoral head published from 1990 to 2016. The pathological changes of alcoholic osteonecrosis of the femoral head were overviewed.
RESULTS AND CONCLUSION: There are various theories about the pathogenesis of alcoholic osteonecrosis of the femoral head, but the essence is the disturbance of blood circulation in femoral head, and long-term decrease in the nutrients and oxygen supplying of bone leading to bone degeneration and necrosis. Large-dose intake of alcohol will induce the imbalance of oxidation and anti-oxidation system, which dose harm to the microenvironment of femoral head. The change of oxygen supplying accelerates the necrosis of femoral head, the weakened differentiation of bone marrow mesenchymal stem cells into osteoblasts and the disturbance of bone resorption-formation imbalance finally result in the necrosis and collapse of femoral head. It is expected to provide a new therapeutic strategy for delaying or preventing the early femoral head necrosis by controlling the microenvironment of femoral head.
