[摘要] 目的 研究糖尿病足患者血浆同型半胱氨酸水平的变化及其临床意义。 方法 选取2014年4月—2015年5月该院收治的75例糖尿病患者为研究对象,分为糖尿病足组(DF组)37例和糖尿病组(DM组)38例,以及31名健康者作为对照组(NC组)。检测Hcy、FFA、C肽及其它生化指标,分析各组之间Hcy水平的变化以及多种生化指标与Hcy升高的相关性。 结果 DF组Hcy水平显著高于DM组和NC组,均差异有统计学意义(P<0.05)。相关性分析显示,DF组中的Hcy与年龄、病程、HbA1c、FFA呈正相关(P<0.05);与HDL-C、C肽呈负相关(P<0.01)。二元Logistic回归分析显示Hcy是糖尿病足的影响因素之一。 结论 Hcy是糖尿病足的影响因素之一,可作为糖尿病足的预警和诊断参考依据之一。

[Abstract] Objective To research the changes and clinical significance of Plasma homocysteine level of diabetes foot patients. Methods 75 cases of diabetes patients from April 2014 to May 2015 were selected as the research objects and divided into the diabetic foot group with 37 cases and diabetes group with 38 cases and 31 cases of health people were selected as the control group, and the Hcy, FFA, C peptide and other biochemical indexes were tested and the changes of Hcy level and correlation between most biochemical indexes and increase of Hcy in each group were analyzed. Results The Hcy level in the DF group was obviously higher than that in the DM group and NC group(P<0.05), and the correlation analysis showed that the Hcy in the DF group was positively correlated with the age, disease course, HbA1c, FFA(P<0.05), negatively correlated with HDL-C and C peptide(P<0.01), and the binary logistic regression analysis showed that Hcy was one of the influence factors of diabetic foot. Conclusion Hcy is one of the influence factors of diabetic foot, which can be used as one of the precaution and diagnosis of diabetic foot.

空腹血漿总同型半胱氨酸(homocysteine ,Hcy)是一种含硫基的氨基酸,是蛋氨酸代谢的中间产物[1],在体内的代谢需要叶酸和维生素B12的参与,糖尿病(DM)患者由于代谢紊乱导致体内叶酸和维生素B12的缺乏,从而引起体内Hcy水平升高。Hcy参与了血管内皮细胞的潜在改变,可直接或间接导致血管内皮细胞损伤,促进血管平滑肌细胞增殖,影响低密度脂蛋白的氧化,增强血小板功能,在动脉粥样硬化和血栓形成中发挥作用[2-3]。在糖尿病患者中,胰岛素是影响Hcy水平的重要因素之一,胰岛素可以通过调节肝转硫基酶的活性调节Hcy的浓度。近几年的多项研究显示,2型糖尿病大血管病变(如冠状动脉病变、脑血管病变、外周血管病变))与高Hcy血症密切相关[4]。对糖尿病微血管病变与Hcy血症相关性的研究也逐年增多,但存在许多争议。目前,国内外对Hcy与DF发病及进展的影响和相关性研究和报道较少。该研究选取2014年4月—2015年5月收治的75例患者和31名健康者为研究对象,通过对DF患者的Hcy及相关生化资料进行分析、旨在探讨DF患者Hcy水平变化及与其它生化指标的相关性现,报道如下。……
