老年糖尿病患者由于糖代谢紊乱、周围血管神经病变,加上血液流变性异常,导致血流缓慢、淤滞,影响微循环灌注及氧交换,使神经组织缺血缺氧而引起皮肤损害,且年龄越高、血糖值越高、血浆蛋白越低,皮肤病变发生率越高[1]。根据Giigor和Lazarus的资料,30%的糖尿病患者有皮肤损害,40岁以上患者比非糖尿病患者高50倍[2]。2007年1月以来,我们 Elderly diabetic patients due to disorders of glucose metabolism, peripheral vascular neuropathy, coupled with abnormal blood rheology, leading to slow blood flow, stasis, affecting microcirculation perfusion and oxygen exchange, nerve tissue ischemia and hypoxia caused by skin damage, and age High, the higher the blood glucose level, the lower the plasma protein, the higher the incidence of skin lesions [1]. According to Giigor and Lazarus, 30% of diabetic patients have skin lesions, and those over 40 years of age are 50 times more likely to have non-diabetic patients [2]. Since January 2007, we
