摘要: 摘要: 目的 探讨微小 RNA-137 (miR-137) 单核苷酸多态性 (SNP) 位点 rs1625579 多态性与精神分裂症患者认 知功能的相关性。方法 选取 250 例精神分裂症患者, 采用阳性和阴性症状量表(PANSS)评估精神分裂症患者症 状, 简明精神分裂症认知评估测验量表 (BACS) 评估精神分裂症患者的认知功能。并收集患者外周血液, 采用 SNaP⁃ shot 技术对 rs1625579 位点进行基因分型。比较该位点不同基因型的症状及认知功能差异。结果 TT、 GT、 GG 基 因型分别为 221 例 (88.4%)、 28 例 (11.2%)、 1 例 (0.4%)。TT 基因型和 G 等位基因 (GG+GT) 携带者 PANSS 评分差异 无统计学意义。BACS 测验结果显示, 除数字序列测验 TT 基因型患者得分低于 G 等位基因 (GG+GT) 携带者外 (P < 0.05), 语义流畅性测验、 字词流畅性测验、 言语记忆测验、 代币运动、 伦敦塔测验、 符号编码测验得分 TT 基因型与 G 等位基因(GG+GT)携带者间差异均无统计学意义。结论 miR-137 基因 rs1625579 位点多态性可能与中国汉族人 群精神分裂症工作记忆能力有关.

Abstract: Abstract: Objective To investigate the aassociation of a microRNA-137 (miR-137) polymorphism, single nucleotide polymorphism (SNP) rs1625579, with neurocognitive function in patients with schizophrenia. Methods A total of 250 patients with schizophrenia were included in this study. The positive and negative syndrome scale (PANSS) was used to evaluate patients. The brief assessment of cognition in schizophrenia (BACS) scale was used to determine neurocongnitive functions in patients. Blood samples of patients were collected, and SNaPshot technique was used to compare the neurocognitive functions of different genotypes of rs1625579. Results The genotypes of TT, GT and GG were 221 (88.4%), 28 (11.2%) and 1(0.4%). There was no significant difference in PANSS score between TT genotype carriers and G allele (GG+GT) carriers. The detection of BACS showed that the digit sequencing score was significantly lower in patients with TT genotype than that of G allele (GG+GT) carrier (P < 0.05). There were no significant differences in other scores of BACS evaluation between two groups of patients. Conclusion The miR-137 polymorphism influences the working memory performance of schizophrenic patients in Chinese Han population.
