研究目的:

1.明确叶酸、维生素B12、同型半胱氨酸水平在糖尿病足不同风险组间存在差异。 2.证实联合叶酸、维生素B12、同型半胱氨酸等指标可成为筛查糖尿病高危足的有用指标。 3.通过测定叶酸、维生素B12、同型半胱氨酸及叶酸/维生素B12比率,尝试探讨给予糖尿病高危足患者营养干预的时机。  

Objectives of Study:

1. To clarify the differences in folate, vitamin B12, and homocysteine levels among different risk groups for diabetic foot ulcers. 2. To confirm that a combination of folate, vitamin B12, and homocysteine can be useful indicators for screening high-risk diabetic feet. 3. By measuring folate, vitamin B12, homocysteine, and the folate/vitamin B12 ratio, we aim to explore the timing of nutritional intervention for patients at high risk for diabetic foot ulcers.
