摘要
目的:本研究的目的是调查血清内源性大麻素(eCBs;anandamide: AEA和2-花生四烯醇甘油:2-AG)和每日摄入的多不饱和脂肪酸(PUFAs;花生四烯酸:ARA，二十二碳六烯酸:DHA和二十碳五烯酸:EPA)在高抑郁症状和低抑郁症状的受试者中存在差异。方法:研究对象为日本40岁以上的女性社区居民。在208名女性受试者中，选取14名高抑郁症状受试者和10名低抑郁症状受试者进行研究。抑郁症状由日本版流行病学研究中心抑郁量表(CES-D)测量。使用简短的自我管理饮食史问卷来评估PUFAs的每日摄入量。分析血中AEA、2-AG和CB受体1基因(CNR1)单核苷酸多态性(SNP) rs806377。结果:即使在控制混杂因素后，高抑郁参与者的AEA血清水平与ARA摄入量之比(AEA/ARA)也显著高于低抑郁参与者，而高ce - d评分组和低ce - d评分组之间的血清eCBs浓度、PUFAs日摄入量以及CNR1 SNP (rs806377)无显著差异。结论:高抑郁被试中AEA/ARA水平的升高表明抑郁个体中ARA向AEA的转化速度可能加快。
Elevated ratio of serum anandamide to arachidonic acid intake in community-dwelling women with high depressive symptoms.
Objectives: The purpose of the present study was to investigate the serum levels of endocannabinoids (eCBs; anandamide: AEA and 2-arachidonoylglycerol: 2-AG) and daily intake of polyunsaturated fatty acids (PUFAs; arachidonic acid: ARA, docosahexaenoic acid: DHA, and eicosapentaenoic acid: EPA) among subjects with high and low depressive symptoms.
Methods: The participants comprised female community-dwellers aged 40 years or older in Japan. Among 208 females, fourteen participants with high depressive symptoms and ten participants with low depressive symptoms were selected for this study. The depressive symptoms were measured by the Japanese version of the Centre for Epidemiologic Studies Depression Scale (CES-D). The daily intake of PUFAs were assessed utilising the brief-type self-administered diet history questionnaire. The blood samples were analysed for AEA, 2-AG, and the CB receptor 1 gene (CNR1) single nucleotide polymorphism (SNP) rs806377.
Results: The ratio of AEA serum level to ARA intake (AEA/ARA) in high depressive participants was significantly higher compared with those in low depressive participants even after controlling for confounders, whereas there were no significant differences in the serum concentrations of eCBs, daily intake of PUFAs, as well as the CNR1 SNP (rs806377) between the high and low CES-D scored groups.
Conclusion: The elevated level of AEA/ARA among high depressive participants suggests that the conversion rate of ARA to AEA may be accelerated in depressive individuals.
