研究目的:

本研究拟通过6个月的随机双盲对照设计,招募90名40-70岁的NAFLD患者,按1:1比例随机分配至两组分别接受1600IU/d的维生素D和安慰剂,在基线及干预3、6个月时抽取晨起空腹血,检测血清转氨酶、血糖、脂质等指标,利用重复测量资料的方差分析比较干预前后两组肝功能相关代谢指标之间的差异,检验维生素D补充对NAFLD防治效果;检测血清空腹胰岛素,炎性因子以及脂肪细胞因子,利用中介效应模型分析上述指标在维生素D作用于NAFLD病因链上所起的作用,阐明维生素D影响NAFLD的可能机制及作用大小。  

Objectives of Study:

With the aim to evaluate the therapy effects of vitamin D on NAFLD, we proposed a randomized, double-blinded, placebo-controlled trial, including 90 people aged 40-70 years, and will randomly assign them to receive either 1600IU/d vitamin D or placebo for 6 months. Blood will be collected at baseline, 3 and 6 months. The serum transaminase, fasting glucose, insulin and lipids profiles will be determined. The one-way repeated analysis of variance and analysis of covariance will be applied to detect the differences of metabolic profiles between groups. The insulin resistant level, inflammation markers and adipocyte cytokines will be measured. To address the potential mechanism of NAFLD, mediation analyses will be used to determine the role of insulin resistant level, inflammation status and adipocyte cytokines in the causal chain between vitamin D and the clinical markers of NAFLD.

随机方法(请说明由何人用什么方法产生随机序列):

采用最小化法,以年龄(40~50岁,50~60岁,60~70岁)、性别(男/女)、NAFLD影像学严重程度(轻/中/重)作为预后因素将90名研究对象分为2组。1-90号所对应的组别由不透明的信封封存。随机方法的实施由不参与本项研究的人员进行,并由其单独保管相关分组过程资料。预试验结束后,按照进入干预的顺序,通过抽签法将各序号及对应的干预方案分派至各研究对象。

Randomization Procedure (please state who generates the random number sequence and by what method):

Ninety subjects will be assigned to two groups using minimization method according to the age, sex and the severity of NAFLD. Researchers who had no contact with the study participants and were not involved in data collection and analysis performed the randomisation procedure and the labelling work.
