摘      要：BACKGROUND： Studies addressing the correlation between prion protein gene codon 129 polymorphism, Alzheimer＇s disease, and cognitive disorders have mainly focused on Caucasians. However, prion protein gene codon 129 polymorphism is thought to also affect the Chinese Han and Wei populations. OBJECTIVE： To analyze the differences of prion protein gene codon 129 distribution among the elderly Chinese Han, East Asian, and Caucasian populations, and to study the correlation between prion protein gene codon 129 distribution and late-onset Alzheimer＇s disease. DESIGN, TIME AND SETTING： A gene polymorphism analysis was performed in the Institute of Geriatrics, General Hospital of Chinese PLA between January 2006 and January 2007. PARTICIPANTS： A total of 152 elderly Chinese Han people were selected from the Beijing Troop Cadre＇s Sanitarium. Among them, 60 patients with late-onset Alzheimer＇s disease, with a mean age of （82 ± 7） years （range 67-94 years） and disease course of （5.9 ± 4.4） years, comprising 44 males with a mean age of （83 ± 7） years and 16 females with a mean age of （78 ±7） years, were selected for the case group. An additional 92 healthy elderly subjects, with a mean of （76 ± 9） years （range 60-94 years）, comprising 76 males with a mean age of （77 ± 9） years and 16 females with a mean age of （70 ± 8） years, were selected for the control group. There were no significant differences in age and gender between the two groups （P〉 0.05）. METHODS： DNA was extracted from peripheral blood leukocytes using routine phenol/chloroform methodology. Prion protein gene codon 129 potymorphism and ApoE polymorphism were measured using PCR-restriction fragment length polymorphism. The ApoEε allele was considered the standard for analyzing correlations between prion protein gene codon 129 polymorphism and late-onset Alzheimer＇s disease. MAIN OUTCOME MEASURES： Prion protein gene codon 129 distribution; correlation between genotypic frequency and allele frequency of prion protei
