脐带间充质干细胞移植治疗糖尿病下肢血管病变

背景：与骨髓和自体外周血干细胞相比,脐带间充质干细胞更原始,扩增能力更强,且免疫原性弱,无伦理问题,对于年老体弱的糖尿病患者更具有重要意义。目的：分析脐带间充质干细胞移植治疗糖尿病下肢血管病变的有效性和安全性。方法：56例中老年2型糖尿病下肢血管病变患者,随机分为对照组和观察组,对照组采用常规药物治疗,观察组采用脐带间充质干细胞移植治疗。结果与结论：观察组临床显效率高于对照组的临床显效率,差异有显著性意义（P〈0.05）;两组治疗后皮温、经皮氧、踝肱指数值均有好转表现,观察组踝肱指数值好转更明显（P〈0.05）;两组均未发现明显的不良反应。结果可见脐带间充质干细胞移植治疗糖尿病下肢血管病变是一种简便、安全、有效的治疗方法,近期疗效显著。

Umbilical cord mesenchymal stem cell transplantation for treatment of diabetic lower limb vascular disease

BACKGROUND：Compared with bone marrow and autologous peripheral blood stem cells, umbilical cord mesenchymal stem cells are characterized as more primitive, more powerful amplification and lower immunogenicity, no ethical problems, which are more important to the elderly patients with diabetes mel itus. OBJECTIVE：To evaluate the efficacy and safety of umbilical cord mesenchymal stem cells transplantation in the treatment of the elderly patients with diabetic lower limb vascular disease. METHODS：Fifty-six elderly patients with diabetic lower limb vascular disease were randomly divided into observation group and control group. The control group was treated with conventional therapy, while the observation group was treated with umbilical cord mesenchymal stem cells transplantation. RESULTS AND CONCLUSION：Observation group showed a higher efficiency than the control group, with significant difference （P〈0.05）. After treatment, foot skin temperature, transcutaneous oxygen pressure, and ankle brachial index were al improved in both two groups, and the ankle brachial index showed a better value in the observation group （P〈0.05）. There were no significant adverse reactions in the two groups. Umbilical cord mesenchymal stem cells transplantation is a simple, safe and effective therapy for the elderly patients with diabetic lower limb vascular disease, with better short-term curative effect.
