研究目的: |
本项目拟利用多模态磁共振技术,从脑结构、功能、连接和网络等多角度探究维生素D、维生素D受体基因多态性与脑小血管病的联系模式,重点阐述补充维生素D对大脑结构、功能、连接和网络的治疗效果,提高对维生素D和脑小血管病之间联系的遗传学及神经机制的全面认识。 |

|
Objectives of Study: |
To explore the association between vitamin D, gene polymorphism of vitamin D receptor and cerebral small vascular disease from the perspective of brain structure, function, connectivity and network, the multimodal magnetic resonance imaging technology is used. Further, we focus on the therapeutic effect of vitamin D supplementation on brain structure, function, connectivity and network. We aim to improve the overall understanding of the genetic and neural mechanisms between vitamin D and cerebral small vascular disease. |

药物成份或治疗方案详述: |
实验组:在基线水平测定血清中的维生素D [25(OH)D],小于30 ng/ml(75 nmol/L)为低维生素D组,予以口服维生素D滴剂(胶囊),400iu/粒,治疗剂量800iu BID,用药总疗程为12个月,根据病情配合常规降压、降糖、降脂药物; 对照组:根据病情常规服用降压、降糖、降脂药物; 两组在服药过程中禁用其他改善脑血液循环的药物和其他 B 族维生素。 |

|
Description for medicine or protocol of treatment in detail: |
Experimental group: The baseline level of serum vitamin D [25(OH)D] is detected. The low-level vitamin D group (less than 30 ng/ml or 75 nmol/L) are given oral vitamin D drops or capsules with a therapeutic dose of 800iu BID for 12 months. The conventional antihypertensive, hypoglycemic, lipid-lowering drugs are given as needed at the same time; Control group: The conventional antihypertensive, hypoglycemic, lipid-lowering drugs are given as needed; Drugs which used to improve circulation of the brain and vitamin B are unusable during the course of the medication. |
