研究目的: |
孤独症谱系障碍(autism spectrum disorder, ASD)因其逐年攀升的患病率、高致残率、给社会及家庭带来沉重负担,是一项公共卫生问题。营养在内的环境因素在ASD发病机制中的研究是热点,也是尚未阐明的难点。申请人前期及他人研究表明ASD患者维生素A缺乏(vitamin A deficiency,VAD)率高,且与ASD严重程度密切相关;维生素A活性代谢产物视黄酸(retinoic acid,RA)干预ASD大鼠模型及ASD人群社交核心症状缓解。多发性硬化模型中RA可抑制Th17细胞表达及IL-17(IL-17A)的分泌,而Th17细胞及其分泌的IL-17(IL-17A)直接参与ASD发病。为此,申请人拟以前期工作为基础,通过人群横断面、前瞻队列研究及体外细胞实验,深入研究VAD是否通过加速Th17细胞表达、IL-17(IL-17A)的分泌,加重ASD症状,为维生素A用于ASD干预的新思路提供理论依据。 |

Objectives of Study: |
Autism spectrum disorder (ASD) is a public health problem with its increasing prevalence, high disability rate and heavy burden on society and families.Though many studies focused on the roles of environmental factors including nutrition in ASD ,it has not yet been well illustrated. The prevalence of vitamin A deficiency (VAD) in ASD patients was high, and it was significantly related to the severity of ASD; Retinoic acid (RA), an active metabolite of vitamin A, could improve autism symptoms in both autistic human and rat. In multiple sclerosis model, RA can inhibit the expression of Th17 cells and the secretion of IL-17 (IL-17A), while Th17 cells and their secreted IL-17 (IL-17A) are directly involved in the pathogenesis of ASD. We aimed to explore whether VAD can aggravate ASD symptoms by accelerating the expression of Th17 cells and the secretion of IL-17 (IL-17A),with cross-section, prospective cohort study and in vitro cell experiment, which will provide evidence for future studies of neuropathological mechanism and intervention of vitamin A in ASD. |
