精神分裂症患者血浆miRNA表达水平与精神症状的关系研究

目的 探讨精神分裂症患者血浆中miRNA表达水平与精神症状的关系。方法 连续纳入2012年7月-2013年5月收治的53例未经药物治疗的精神分裂症患者,采用实时荧光定量PCR技术检测血浆中9种miRNA(miR-30e、miR-34a、miR-181b、miR-195、miR-346、miR-432、miR-7、miR-132、miR-212)的表达水平,采用阳性和阴性症状量表(PANSS)评估其精神症状,并对结果进行统计学分析。结果 miR-34a与激活性症状及攻击性症状呈显著负相关(r=–0.345、–0.284,P〈0.05),miR-346与一般精神病理症状呈明显负相关(r=–0.28...

Summary:目的 探讨精神分裂症患者血浆中miRNA表达水平与精神症状的关系。方法 连续纳入2012年7月-2013年5月收治的53例未经药物治疗的精神分裂症患者,采用实时荧光定量PCR技术检测血浆中9种miRNA(miR-30e、miR-34a、miR-181b、miR-195、miR-346、miR-432、miR-7、miR-132、miR-212)的表达水平,采用阳性和阴性症状量表(PANSS)评估其精神症状,并对结果进行统计学分析。结果 miR-34a与激活性症状及攻击性症状呈显著负相关(r=–0.345、–0.284,P〈0.05),miR-346与一般精神病理症状呈明显负相关(r=–0.282,P〈0.05)。miR-34a高表达组激活性症状群分和攻击性症状群分显著低于低表达组(P〈0.05),miR-346高表达组反应缺乏症状群分显著低于低表达组(P〈0.05)。miR-34a分别进入以激活性症状群和攻击性症状群为因变量的回归方程,可解释激活性症状变异的10.2%,攻击性症状群变异的6.3%;miR-346进入以一般精神病理症状为因变量的回归方程,可解释一般精神病理变异的6.1%。结论 精神分裂症患者血浆中的miR-34a与激活性症状、攻击性症状有明显关联,miR-346与一般精神病理症状有明显关联,此二者可能在上述精神症状的发生发展过程中起重要作用。

Methods A total of 53 consecutive schizophrenia patients who had not received antipsychotic treatment from July 2012 to May 2013 were enrolled in the present study. The expressions of 9 schizophrenia-associated microRNAs (miR30e, miR-34a, miR-181b, miR-195, miR-346, miR-432, miR-7, miR-132 and miR-212) in plasma were determined by real-time fluorescence quantitative PCR, with the psychiatric symptoms evaluated by Positive and Negative Symptoms Scale (PANSS), and the results were analyzed statistically. Results The expression level of miRNA-34a was significantly negatively correlated with the active symptoms and aggressive symptoms (r=–0.345, r=–0.284, P〈0.05), and the expression level of miRNA-346 was significantly negatively correlated with the general psychopathologic symptoms (r=–0.282, P〈0.05). The scores of activity and aggressiveness in the higher expression subgroup of miRN
