Effect of paeoniflorin on distal survival of random flaps.

Background: Distal ischemic necrosisis a common complication of orthopedic random skin flaps surgery. Paeoniflorin, a natural compound extracted from Paeonia lactiflora, can enhances angiogenesis and alleviates excessive inflammatory response. We investigated the changes of ischemic extra-long flaps with paeoniflorin and its possible mechanism.

Exenatide inhibits necrosis by enhancing angiogenesis and ameliorating ischemia/reperfusion injury in a random skin flap rat model.

Background: Random skin flaps are often used for plastic repair because they are convenient and flexible. However, necrosis of flaps is a common complication that may lead to disastrous consequences. Exenatide, a glucagon-like peptide 1 receptor agonist, can enhance angiogenesis and ameliorate ischemia/reperfusion injury.

Angiogenic and anti-inflammatory properties of azadirachtin A improve random skin flap survival in rats.

Random skin flaps are widely used to repair tissue defects. However, the distal flap regions are prone to ischemic necrosis, limiting clinical applications. Azadirachtin A, a fruit extract from the neem, improves tissue blood supply and metabolism, reduces cell swelling, promotes tissue healing, and prevents venous thrombosis.
