Flow-through arterialized venous free thenar flaps for palmar soft tissue defects in fingers

ObjectiveTo evaluate the efficacy of venous free thenar flaps for reconstructing palmar soft tissue defects in fingers.MethodsFrom December 2018 to October 2019, 11 patients with palmar soft tissue defects in fingers were treated using venous free thenar flaps. At the final follow-up, the range of thumb radial and palmar abduction on the injured side and opposite side was calculated. The total active movement (TAM) of the injured and opposite fingers and flap sensibility recovery were also recorded.ResultsThe mean follow-up time was 13.4 months, all flaps survived, and all wounds at the donor sites healed with no skin necrosis. At the last follow-up, the average range of thumb radial abduction and thumb palmar abduction on the injured side was 96.6% and 95.9% of the value on the opposite side, respectively. The average TAM of the injured fingers was 98.2% of the value of the opposite fingers. Sensation in the flaps was restored to grade S2 to S3.ConclusionVenous free thenar flaps can be alternatives for reconstructing palmar soft tissue defects in fingers.     

臭茉莉叶总黄酮提取工艺优化及月周期变化研究

目的:采用超声辅助正交试验法优化臭茉莉叶总黄酮的提取工艺,并进一步研究臭茉莉叶中总黄酮1年内每月含量变化趋势,探讨臭茉莉叶最佳采收时间。方法:以提取液中总黄酮含量为指标,选择乙醇浓度(%)、超声时间(min)、料液比、提取温度(℃)等为考察因素,采用正交试验法L9(34)确定臭茉莉叶提取液中总黄酮的最优工艺。结果:臭茉莉叶所含总黄酮最优提取工艺条件:乙醇浓度70%、超声时间60min、料液比1∶25、提取温度50℃。3月份总黄酮/药材量是0.0235mg·g-1为最高。结论:该提取工艺快捷以及操作简便,适用于臭茉莉叶总黄酮的提取。结合总黄酮月周期变化规律,可以确定1年中5月份和7月份为最佳采摘期。
