[摘要] 长久以来,维生素D在维持人体钙稳态、促使骨骼健康与预防骨折方面具有经典作用。新近的研究显示,维生素D可能通过多种机制参与并影响动脉粥样硬化的发展。在以动脉粥样硬化为病理基础的心血管疾病的发展方面,低维生素D作为新的潜在的危险因素,具有重要研究意义。关于维生素D与动脉粥样硬化之间的关联性调查在过去十年中已经呈现出巨大的发展势头,该文将在总结国内外相关临床研究和实验数据的基础上,对二者之间的生物学联系及研究进展作一综述。

[Abstract] For a long time, vitamin D has a classic role in maintaining calcium homeostasis, promoting bone health and preventing fractures. Recent studies have shown that vitamin D may participate in and affect the development of atherosclerosis through a variety of mechanisms. In the development of cardiovascular disease based on atherosclerosis, low vitamin D as a new potential risk factor has important research significance. The investigation on the relationship between vitamin D and atherosclerosis has shown great development momentum in the past decade. This article will summarize the clinical research and experimental data at home and abroad on the basis of the biological relationship between the two. A review of the academic links and research progress was made.

自20世纪20年代起,人们就发现骨骼代谢与健康与维生素D状态密切相关。并且,越来越多关于维生素D领域的文献表明其在调节体内稳态的许多过程中同样具有重要作用。研究者们通过不断探讨维生素D的非骨骼作用,发现维生素D缺乏与心血管疾病(Cardiovascular Disease,CVD)以及高血压风险增加相关[1],维生素D在心血管疾病形成过程中具有抗动脉粥样硬化作用[2]。
1 维生素D的合成与代谢
维生素D是一类人体必需的脂溶性类固醇激素,包括两种天然化合物:维生素D2,它是通过饮食获得的;维生素D3,它来自饮食和内源性合成。紫外线B射线(295-310 nm)将皮肤前体7-脱氢胆固醇转化为维生素D3(胆钙化醇),其需要两次连续羟基化以形成活性维生素D3。第一次羟基化发生在肝脏中,通过25-羟化酶的作用产生25(OH)D3。……
