麻省理工学院工程师创造了一个可生物降解的补丁,在心脏病发作后按顺序提供药物以修复心脏组织,将老鼠的损害减少50%。 MIT engineers created a biodegradable patch that delivers drugs in sequence to repair heart tissue after a heart attack, reducing damage by 50% in rats.

麻省理工学院工程师开发了一个可生物降解的灵活补丁 以精确的顺序提供药物 以便在心脏病发作后修复心脏组织 MIT engineers have developed a biodegradable, flexible patch that delivers drugs in a precise sequence to repair heart tissue after a heart attack. 它在手术期间植入,释放了奈尔古林-1(neuregulin-1)以防止细胞死亡,释放了VEGF(VEGF)来培育血管,释放了GW788388(GW788388)来减少伤疤,与心脏的自然愈合时间吻合。 Implanted during surgery, it releases neuregulin-1 to prevent cell death, VEGF to grow blood vessels, and GW788388 to reduce scarring, matching the heart’s natural healing timeline. 在老鼠研究中 补丁割伤组织 减少了50% 心脏功能得到改善 In rat studies, the patch cut damaged tissue by 50% and improved heart function. 它由安全、可降解的材料制成,仍在临床前测试中,但总有一天可以改变心脏病发作病人的康复。 Made from safe, degradable materials, it is still in preclinical testing but could one day transform recovery for heart attack patients.
