摘  要:目的:通过分析首发未服药精神分裂症患者血清同型半胱氨酸(Hcy)水平与临床特征的关系,探讨Hcy在精神分裂症发病机制中可能的作用。方法:根据美国精神疾病诊断统计手册第4版(DSM-IV)和国际疾病和相关健康问题统计分类第十版(ICD-10)精神分裂症诊断标准,纳入首发未服药的精神分裂症患者56例;并选取年龄、性别匹配的正常对照56例。采用阳性和阴性症状量表(PANSS)评估精神分裂症患者组的精神病理症状;采用酶联免疫吸附法(ELISA)检测所有受试对象的血清Hcy水平。比较两组血清Hcy水平,分析血清Hcy水平与年龄、病程、体质量指数(BMI)以及PANSS评分间的关联。结果:精神分裂症组的血清Hcy水平显著高于对照组[(11.2±4.5)mol/L vs.(6.0.±3.6)mol/L,P<0.001],血清Hcy水平与PANSS总分(r=0.28)及阴性症状总分(r=0.52)呈正相关(均P<0.05)。结论:本研究显示,首发未服药精神分裂症患者血清Hcy升高且与较高的阴性症状严重程度有关。Objective: To explore the role of homocysteine( Hcy) in the pathogenesis of schizophrenia by analyzing the correlation betw een serum Hcy levels and clinical traits in the first-episode drug-native patients w ith schizophrenia. Methods: Fifty-six first-episode drug-native patients w ith schizophrenia meeting the diagnostic criteria of the Diagnostic and Statistical Manual of Mental Disorder,Fourth Edition( DSM-IV) and International Statistical Classification of Diseases and Related Health Problem, Tenth Revision( ICD-10), and 56 age-and gendermatched normal controls( n = 56) w ere selected. Patients ' psychopathological parameters w ere assessed w ith the Positive and Negative Syndrome Scale( PANSS) and the serum Hcy level w as measured by using enzyme linked immunosorbent assay( ELISA). The difference of Hcy levels betw een the tw o groups w ere compared and the correlations of serum Hcy levels to age,duration of illness,body mass index( BMI) and the score of the PANSS w ere analyzed. Results: The serum Hcy levels w ere higher in patients w ith schizophrenia than in controls [( 11. 2 ± 4. 5)mol / L vs.( 6. 0 ± 3. 6) mol / L,P〈0. 01]. The serum Hcy levels w ere positively correlated w ith the PANSS total scores and the negative symptom sub-scores( r = 0. 28,0. 52; P〈0. 05). Conclusion: It suggests that serum Hcy levels are elevated in patients w ith first-episode drug-na¨ive schizophrenia and be associated w ith severer negative symptoms of schizophrenia.
