摘要
目的研究载脂蛋白E(ApoE)ε4等位基因与老年人术后认知功能障碍(POCD)之间的相关性。方法使用中文版韦氏成人智力量表(WAIS)和韦氏记忆量表(WMS)对患者进行术前1d和术后7d的神经、精神功能测试。对30例POCD老年患者和30名健康老年人(对照组)做ApoE的基因分型鉴定并进行比较。结果ApoEε3/ε4型频率(28.3%)和ApoEε4等位基因频率(17.8%)均高于对照组(9.6%,4.9%)。两组比较有统计学意义(P<0.01)。结论ApoEε4等位基因是对老年人认知功能产生有害影响的因素,可使认知障碍加重;老年人POCD和ApoEε4基因的关系在统计学上存在着相关性。
Objective To study the correlation between the apolipoprotein ε4 allele and postoperative cognitive dysfunction in the elderly. Methods The patients (pts) were divided into postoperative cognitive dysfunction (POCD) group and normal group. Cognitive function was evaluated by nine neuro - psychological tests before operation, at one week after operation. ApoE allele genotype were detected and compared. Results The frequencies of ApoEε3/ε4 phenotype(28.3 % ) and ApoEε4 alleles (17.8 %) were higher in POCD group than that in the normal group (P〈0. 01). Conclusion ApoEε4 allele gene could be regarded as a harmful factor to senile cognitive function. The ApoE genotype had a close correlation with postoperative cognitive dysfunction in the elderly.
