分析31例DF患者临床资料。结果60岁以上占51.6%且男性多于女性占64.5%,糖尿病病程5年以上占83.5%且血糖、血脂控制不良,合并血管病变者占64.5%,合并神经病变合者占71.8%。结论DF发生,发展与高血糖、血管神经病变、高血脂、年龄等危险因素有关。 Clinical data of 31 patients with DF were analyzed. Results 51.6% were over the age of 60 and 64.5% were male and female. The duration of diabetes over 5 years accounted for 83.5% and blood glucose and dyslipidemia were poorly controlled. 64.5% had vascular disease and 71.8% had neuropathies. Conclusions The occurrence and development of DF are related to risk factors such as hyperglycemia, vascular neuropathy, hyperlipidemia and age.
