【摘要】:
目的 探讨N-甲基-D-天冬氨酸受体2B亚基(NR2B)基因启动子区甲基化水平与双相抑郁患者失眠相关执行功能损害的相关性,为双相抑郁患者的早期诊断及临床治疗提供理论依据。

方法 本研究为病例对照研究,收集双相抑郁患者31例及健康对照16例,根据临床上有无失眠症状及匹兹堡睡眠质量指数(PSQI)分值将双相抑郁患者分为失眠组(PSQI≥7分)及非失眠组(PSQI<7分)。测定所有受试者外周血NR2B基因启动子区甲基化水平,采用偏相关分析其与双相抑郁患者失眠相关执行功能损害的相关性以及先单后多因素Logistics回归分析其与双相抑郁患者失眠症状的关联。

结果 非失眠组、失眠组CpG3及CpG10甲基化率高于健康对照组;失眠组CpG7甲基化率低于健康对照组,CpG9甲基化率高于非失眠组(P<0.05)。偏相关分析显示,CpG10甲基化率与斯特鲁普色词测验(Stroop Color and Word Test,SCWT)单词个数(r=0.569)及颜色个数(r=0.526)呈中度正相关(P<0.05),CpG6甲基化率与SWCT色词个数呈中度正相关(r=0.558,P<0.05)。汉密尔顿抑郁量表(HAMD)评分(P=0.034,OR=0.729,95%CI:0.544~0.976)与位点CpG9甲基化水平的升高(OR=0.814,95%CI:0.677~0.978,P=0.028)为双相抑郁患者失眠症状的独立危险因素。

结论 NR2B基因启动子区甲基化水平异常可能介导双相抑郁患者失眠症状的产生并与失眠相关执行功能受损有关。

ABSTRACT

【Abstract】
Objective To explore the relationship between methylation in the promoter region of N-methyl-D-aspartate receptor 2B subunit (NR2B) gene and insomnia-related executive function impairment in patients with bipolar depression and provide theoretical basis for early diagnosis and clinical treatment of patients with bipolar depression.

Methods This study was a case-control study. 31 patients with bipolar depression and 16 healthy controls were collected. Patients with bipolar depression were divided into insomnia group (PSQI≥7 points) and non-insomnia group (PSQI < 7 points) according to the clinical symptoms of insomnia and the Pittsburgh Sleep Quality index (PSQI) score. The methylation level of NR2B gene promoter in peripheral blood of all subjects was measured. Partial correlation analysis was used to analyze its correlation with insomnia-related executive function impairment in patients with bipolar depression, and its association with insomnia symptoms in patients with bipolar depression was analyzed by Logistics regression.

Results The methylation rates of CpG3 and CpG10 in non-insomnia group and insomnia group were higher than those in healthy control group. The methylation rate of CpG7 in insomnia group was lower than that in healthy control group, and the methylation rate of CpG9 was higher than that in non-insomnia group (P<0.05). Partial correlation analysis showed that the CpG10 methylation rate was moderately positively correlated with the number of words (r=0.569,P<0.05)and colors(r=0.526,P<0.05)in the Stroop Color words Test (SCWT), and the CpG6 methylation rate was moderately positively correlated with the number of color words in SWCT(r=0.558,P<0.05).Multifactor Logistics regression showed that the increased Hamilton Depression Scale (HAMD) score (P = 0.034, OR = 0.729, 95%CI: 0.544 ~ 0.976) and methylation level of CpG9 (OR = 0.814, 95%CI: 0.677 ~ 0.978, P = 0.028) were independent risk factors for insomnia in patients with bipolar depression.

Conclusion   Aberrant methylation in the promoter region of NR2B gene may mediate insomnia in patients with bipolar depression and may be related to the impairment of executive function related to insomnia.
