目的：探讨p22phox C242T 基因多态性与汉族人群迟发性阿尔茨海默病（LOAD）的相关性。方法采用病例对照研究方法，选取276例L O A D患者和320例健康老年人作为研究对象，基因型通过 PCR‐RFLP 方法完成，比较不同基因型与 LOAD 的关系。结果未发现 p22phox C242T 多态性与LOAD存在相关，但经过 ApoE ε4进行分层分析，结果显示ApoE ε4携带者组CT＋ T T基因型与等位基因 T 在LOAD和对照组中的分布存在显著差异（ P ＜0．05），T 等位基因的存在使发生L O A D的风险增加了3．301倍（O R＝3．301，95％ C I＝1．225–8．897， P ＝0．023）。结论 p22phox C242T 基因多态性可能与汉族人群ApoEε4携带者的LOAD发病存在相关性。

Objective To investigate potential associations of the p22phox C242T polymorphism with the risk of late‐onset AD (LOAD) in a northern Han Chinese population .Methods Patients with LOAD (N=276) and 320 control subjects were recruited for the study .Polymerase chain reaction‐restriction fragment length polymorphism was used to detect the genotypes .Results No significant differences were found be‐tween LOAD and p22phox C242T polymorphism ,but a significant association was obtained in the geno‐type and allele distributions of p22phox C242T between LOAD patients and controls in ApoE ε4 carriers ( P <0 .05) .The presence of allele T increased the risk of developing LOAD by 3 .301 fold (OR=3 .301 , 95% CI :1 .225‐8 .897 ,P = 0 .023) in APOE ε4 allele carriers .Conclusion These results suggested that p22phox C242T polymorphism has a possible role in changing the genetic susceptibility to LOAD in ApoEε4 carriers of this northern Han Chinese population .
