摘要： 目的·研究细胞色素P450 1A2（CYP1A2）基因多态性与奥氮平血药浓度变化之间的关系。方法·以关键词“CYP1A2”“基因多态性”“精神分裂症”“奥氮平”“血药浓度”检索 SinoMed、万方、维普、中国知网、PubMed、Embase、Cochrane Library数据库，检索时间段限定为建库至2018年2月27日，并利用STATA/SE 12.0软件进行统计分析。结果·最终纳入4项病例对照研究，包括330例精神分裂症患者。在CYP1A2基因的-163C>A位点隐性模型（A/A vs C/A+C/C）中，携带纯合突变基因型A/A的患者与携带C/A或C/C基因型的患者相比，其奥氮平血药浓度/剂量比（concentration/dosage ratio，C/D）显著降低。结论·CYP1A2基因-163C>A位点的A/A纯合基因型与奥氮平C/D比值降低具有显著相关性。

Abstract:
Objective · To investigate association of cytochrome P450 1A2 (CYP1A2) gene polymorphisms and serum olanzapine concentration. Methods · Key words including “cytochrome P450 CYP1A2”, “genetic polymorphism”, “antipsychotic”, “olanzapine”, “schizophrenia”, and “serum concentration” were used to search in databases, including SinoMed, Wanfang, Weipu, CNKI, PubMed, Embase and Cochrane Library. The search period was limited the establishment of the database to February 27th, 2018. STATA/SE 12.0 package was applied to conduct statistical analyses. Results · Four studies with a total of 330 schizophrenic patients were included. In the recessive model of CYP1A2 gene -163C>A SNP, patients with A/A genotype had significantly lower olanzapine concentration/dosage ratio (C/D) than patients with C/C or C/A genotype. Conclusion · A/A homozygote of CYP1A2 gene -163C>A SNP is significantly associated with the decreased olanzapine serum concentration.
