摘    要:目的:探讨产后抑郁症患者感觉门控P50 的变化特征,为产后抑郁患者的早期预防提供参考依据。方法:采用配对听觉条件(S1)、测试(S2)刺激范式,对本院2011 年1 月至2012 年6 月收治的26 例产后抑郁症患者(实验组)进行听觉诱发电位P50检测,测量P50 的潜伏期、波幅,并与25 例健康被试者(对照组)的结果进行比较。结果:(1) 与对照组相比,实验组S1-P50 潜伏期(56.62± 17.42) ms vs. (49.86 ± 15.21) ms],S2-P50 潜伏期(57.36 ± 15.42) ms vs. (50.04 ± 16.27) ms]的差异均无统计学意义(P〉0.05);(2)与对照组相比,实验组S1-P50 波幅(3.58 ± 1.72) μV vs. (1.13 ± 0.91) μV]显著降低,差异有统计学意义(P〈0.05);S2-P50 波幅(1.32 ± 1.16) μV vs. (1.48 ± 1.05) μV]差异无统计学意义(P〉0.05);(3) 与对照组相比,实验组S2/S1 波幅比值(1.17 ± 0.26) vs.(0.41 ± 0.13)]显著升高,差异有统计学意义(P〈0.05)。结论:产后抑郁症患者感觉门控抑制能力有缺陷,P50 受损指标可能为评估产后抑郁症患者的潜在生物学指标。

Abstract:Objective: To explore the change characteristics of P50 auditory sensory gating potential in patients with postpartum depression and provide references for the prevention of postpartum depression in early phase. Methods: 26 cases of postpartum depression and 25 cases of healthy subjects were selected, the incubation period and amplitude of P50 was measured by paired clicks auditory condition/testing stimulating paradigm. Results: (1) There was no significant difference for S1-P50 latencies (56.62 ± 17.42) ms vs. (49.86 ± 15.21) ms] and $2-P50 latencies (57.36 ±15.42) ms vs. (50.04 ±16.27) ms] between the experimental group and the control group (p〉0.05). (2) Compared with the control group, the amplitude of S1-P50 was significantly lower (3.58 ±1.72) μV vs. (1.13 ±0.91) μV, P〈0.05], and no significant difference of the amplitude of S2-P50 was (1.32 ± 1.16) μV vs. (1.48 ± 1.05) IxV, P 〉0.05] found between two groups. (3) Compared with the control group, the amplitude ratio of S2/S 1 was significantly higher (1.17 ± 0.26) vs. (0.41 ± 0.13), P〈0.05] in the experimental group. Conclusion: Postpartum depression presented defect on the inhibiting ability of auditory sen- sory gating potential in a certain extent. P50 damaged indicator may be a potential biological marker for the evaluation of postpartum depression.
Keywords:Postpartum depression (PPD)  P50 auditory sensory gating potential  Anditory sensory gating
