[摘要]目的 探討2型糖尿病患者血浆同型半胱氨酸（Hcy）水平及其相关影响因素。方法 选取2016年8月～2017年10月我院收治的150例2型糖尿病患者作为2型糖尿病组，并以同期进行健康体检的60例健康者作为对照组。2型糖尿病组患者根据Hcy是否大于15 μmol/L分为两组，分别为高Hcy组（n=62，Hcy>15 μmol/L）和正常Hcy组（n=88，Hcy≤15 μmol/L）。比较两组受试者Hcy、身体测量指标、血糖、胰岛素、肌酐、血脂、尿酸等水平的差异，并采用多因素Logistic回归分析，探讨2型糖尿病患者血浆Hcy水平的影响因素。结果 2型糖尿病组患者的BMI、尿酸、Hcy、FPG、2 h PG、HOMA-IR、肌酐高于对照组，差异均有统计学意义（P<0.05）。高Hcy组患者的男性比例、年龄、尿酸、HOMA-IR、肌酐水平均显著高于正常Hcy组，差异均有统计学意义（P<0.05）。Logistic回归分析结果显示，2型糖尿病患者中，男性、血尿酸、HOMA-IR是发生高Hcy血症的危险因素（P<0.05）。结论 2型糖尿病患者血浆Hcy水平显著高于健康者，性别、血尿酸、胰岛素抵抗水平均为2型糖尿病患者发生高Hcy血症的危险因素。

[Abstract]Objective To investigate the level of plasma homocysteine （Hcy） and its related factors in patients with type 2 diabetes.Methods A total of 150 patients with type 2 diabetes treated in our hospital from August 2016 to October 2017 were selected as type 2 diabetes group，and 60 healthy persons underwent physical examination in the same period were selected as the control group.The patients in type 2 diabetes group were divided into two groups according to whether Hcy was greater than 15 μmol/L，for the high Hcy group （n=62，Hcy>15 μmol/L） and the normal Hcy group （n=88，Hcy≤15 μmol/L）.The difference of Hcy，body measurement，plasma glucose，insulin，serum creatinine，blood lipid and uric acid were compared between the two groups.The influencing factors of plasma Hcy level in patients with type 2 diabetes were analyzed by multivariate Logistic regression analysis.Results The BMI，uric acid，Hcy，FPG，2 h PG，HOMA-IR and creatinine in type 2 diabetes group were higher than those in the control group，the differences were statistically significant （P<0.05）.The male proportion，age，uric acid，HOMA-IR and creatinine levels of the patients in the high Hcy group were significantly higher than those in the normal Hcy group，and the differences were statistically significant （P<0.05）.Logistic regression analysis showed that in patients with type 2 diabetes，male，blood uric acid and HOMA-IR were risk factors for high Hcy hyperlipidemia （P<0.05）.Conclusion Plasma Hcy level in patients with type 2 diabetes is significantly higher than healthy person.Male，blood uric acid and insulin resistance are risk factors for high Hcy hyperlipidemia in patients with type 2 diabetes.

大量研究证实同型半胱氨酸（homocysteine，Hcy）是心血管疾病的独立危险因素[1-2]，而2型糖尿病患者的血浆Hcy水平高于非糖尿病患者[3]。当前我国患2型糖尿病的人数已超过1亿[4]，了解2型糖尿病患者中Hcy的影响因素，是对其进行针对性干预、降低患者心血管发生风险的基础。因此，本研究通过开展队列研究，探讨2型糖尿病患者的Hcy水平并分析其影响因素，现报道如下。

1.1一般资料

选取2016年8月～2017年10月我院收治的150例2型糖尿病患者作为2型糖尿病组，所有患者均根据WHO糖尿病诊断及分型标准确定诊断[5]。排除标准：①糖尿病急性代谢并发症患者；②存在显性蛋白尿（>0.15 g/d）及肌酐升高患者；③近期服用维生素B6、B12、叶酸等影响Hcy水平的药物者；④患有甲状腺机能亢进、恶性肿瘤及其他影响尿酸代谢疾病的患者。并……
