摘  要:目的探讨新疆地区维吾尔族和汉族人群轻度认知功能障碍(MCI)患者血清25羟维生D[25(0H)D]水平的变化,为其早期干预研究提供科学依据。方法前期对新疆维、汉两民族≥60岁人群进行MCI流行病调查,采用分层随机多级整群抽样的方法,参考美国《精神疾病诊断分类与统计手册》第四版(DSM—IV)中MCI研究应用标准,选取诊断为MCI的患者206例,与其年龄、族别、性别相匹配的正常对照者412例,采用生物素双抗夹心酶联免疫吸附法,测定两组血清中25(OH)D水平。结果(1)两民族MCI组血清25(OH)D水平为(7.89±0.29)μg/L,较对照组(8.65±0.21)μg/L低,差异具有统计学意义(P〈0.05);汉族25(OH)D水平为(8.41±0.34)μg/L,维吾尔族25(OH)D水平为(8.37±0.32)μg/L,差异无统计学意义(P〉0.05);不同性别间比较,女性25(OH)D水平为(8.23±0.32)μg/L,低于男性(8.70±0.42)μg/L,且差异具有统计学意义(P〈0.05);女性MCI组为(7.56±0.34)μg/L,较对照组(8.41±0.31)μg/L低,且差异具有统计学意义(P〈0.05),而男性MCI组25(OH)D水平与对照组比较,差异无统计学意义(P〉0.05)。(2)通过Cox回归模型对MCI进行条件Logistic多因素回归分析,结果显示:低血清25(OH)D水平(OR=1.163,95%CI:0.978~1.447)、非脑力劳动(OR=1.420,95%CI:1.10~1.860)、低文化程度(OR=1.504,95%CI:1.129~2.130)、独身(OR=1.293,95%CI:0.845~1.440)、高血压(OR=1.954,95%CI:1.342~2.670)、糖尿病(OR=1.320,95%CI:1.145~1.710)、吸烟史(OR=1.350,95%CI:1.101~2.293)、高体质指数(BMI)值(OR=1.329,95%CI:1.068~1.781)和MCI的发病相关。结论新疆维、汉两民族MCI患者血清25(OH)D水平低于正常�Objective To investigate changes and the clinical significance of serum 25-Hydroxyvitamin D level in patients of Xinjiang Uygur and Han nationalities with mild cognitive impairment. Methods On the base of early stage of epidemiological survey of Xinjiang Uygur and Han population over 60 years old, adopting multi-stage stratified random cluster sampling method and referencing DSM-Ⅳ, 206 cases of MCI patients (study group)were selected and 412 healthy elderly subjects (control) matching for age, nationality and gender were recruited for case-control study. The serum level of 25(OH) D was measured by enzyme-linked immunosorbent assay (ELISA). Results The serum level of 25(OH)D was significantly lower in MCI group of two nationalities (7.89±0.29 μg/L) than in normal control group [(8.65± 0.21) μg/ml, P〈0.05]. The serum level of 25(OH)D was (8.41±0.34) μg/L in Han group, and (8. 37±0.32)μg/L in Uygur group, with no significant difference (P〉0. 05). The 25(OH)D level was significantly lower in female[(8.23±0.32) μg/L] than in male [(8. 70±0.42) μg/L, P〈0.05]. The serum level of 25(OH)D was lower in female MCI group [(7. 56±0. 34) μg/L] than in female control group [(8.41± 0.31)μg/L], with significant difference (P〈0.05). While there was no significant difference between male MCI and male control group (P〉0.05). Multivariate Cox regression analysis showed that the risk factors of MCI might include low serum 25(OH)D levels (OR=1. 163, 95%CI: 0. 978 1. 447), a decreased physical labor (OR= 1. 420, 95 % CI: 1. 10-1. 860), low edueation degree (OR = 1. 504, 95 % CI: 1. 129-2. 130), celibacy (OR=1.293, 95%CI: 0.845-1.440), hypertension (OR=1.954, 95%CI: 1.342-2.670), diabetes (OR =1. 320, 95% CI: 1. 145-1. 710), smoking history (OR = 1. 350, 95% CI: 1. 101- 2. 293), high BMI (OR=I. 329, 95%CI: 1. 068-1. 781). Conclusions The serum 25(OH)D level is lower in MCI patien
