Neden Önemli?
Globally, nearly 800 million patients suffer from diabetes and its complications. Chronic non-healing wounds are a severe clinical complication, significantly impairing tissue repair ability. This research addresses this critical issue by developing a novel treatment.
中新网北京6月11日电 (记者 孙自法)记者6月11日从中国科学院大学(国科大)获悉，中国科学家团队最新合作研究开发出一种内源性葡萄糖驱动的共生电子绷带(GEB)，可助力糖尿病治疗。
研究团队表示，该电子绷带可直接利用糖尿病患者创面中过量葡萄糖原位发电，在无需外部电源和导线的条件下恢复受损区域内源性电场，为糖尿病患者体内外慢性创面修复提供了自供能、可降解的新型生物电子治疗策略。

这项重要健康研究由国科大欧阳涵副教授团队、国家纳米科学中心陈春英院士团队、清华大学李舟教授团队合作完成，相关成果论文北京时间当天凌晨在国际学术期刊《科学进展》(Science Advances)上线发表。
论文第一作者、国科大纳米学院胥玲玲副教授介绍，研究团队构建了由静电纺丝纤维基底、先进导电网络和酶催化体系组成的柔性电子绷带，并通过葡萄糖氧化酶阳极与阴极协同作用，将创面渗出液中的葡萄糖转化为持续稳定的生物电信号，同时改善高糖微环境，促进细胞迁移、血管生成、胶原沉积和上皮再生。
研究团队还发现，他们研发的内源性葡萄糖驱动的共生电子绷带，能够调控创面免疫微环境，促进巨噬细胞向修复型表型转化，从而减轻慢性炎症并加速组织修复。
在糖尿病小鼠皮肤创面、糖尿病猪全层皮肤缺损以及糖尿病小鼠肠道损伤模型中，该电子绷带均表现出良好的组织贴合性、生物相容性和修复效果。
研究团队表示，这项研究还提出“病理代谢物即治疗能源”的共生生物电子新范式，为植入式生物电子医疗器械的发展提供了新的思路，也为糖尿病创面及多器官组织损伤修复带来潜在临床转化前景。
据悉，全球近8亿患者正遭受糖尿病及其并发症的威胁。除全身性代谢紊乱外，糖尿病还会严重损害组织修复能力，其中慢性难愈性创面，已成为最严重的临床并发症之一。此次研发出内源性葡萄糖驱动的共生电子绷带，有望为糖尿病的慢性难愈性创面治疗带来解决方案。(完)
