Freezing Induced Turn-on Modality for Real-time Imaging in Cryosurgery
摘要： Cryosurgery has attracted great attention for the treatment of tumors due to its obvious advantages. However, it still remains a challenge to determine the volume of frozen tissues in real-time, which greatly lowers the therapeutic efficacy of cryosurgery and hinders its broad application for the treatment of cancers. Herein, we report a freezing induced turn-on strategy for selective real-time imaging of frozen cancer cells. As a type of aggregation induced emission (AIE) fluorogen, TABD-Py molecules interact specifically with ice crystals and form aggregates at the ice/water interface. Consequently, bright fluorescent emission appears upon freezing. Note that TABD-Py molecules are enriched only in the cancer cells and exhibit high biocompatibility as well as low cytotoxicity, therefore a freezing induced turn-on imaging modality for cryosurgery is developed, which will certainly maximize therapeutic efficacy of cryosurgery in treating tumors.

Two-step treatment of bulky keloids on the cheeks after deep chemical peeling: intralesional cryosurgery followed by pulsed dye and ablative fractional CO2 laser
摘要： Scarring of the face following chemical peeling is an uncommon and devastating complication. This case report describes the successful treatment of bulky mature keloids on both cheeks following deep chemical peeling by using a combined approach of intralesional cryosurgery followed by pulsed dye and ablative fractional CO2 laser therapy.
