Progress in research of monitoring microcirculation of replanted tissue by Smartphone-based thermal imaging system / 中华显微外科杂志

Routine vascular observation is not conducive to the early detection of vascular crisis, thus influencing the success rate of replantation surgery. Infrared thermographic imaging (IRT) can be used to monitor the microcirculation of replanted tissue by visually presenting the value of human surface temperature and thermogram. With the rapid progress of science and technology, IRT technology has gradually become mature and reformed. This article reviewed the research on monitoring microcirculation of replanted tissue by Smartphone-based thermal imaging (SBTI) , in order to provide a basis for subsequent research and clinical application.

Literature research on the history of microsurgery in China: A difficult start (1960-1973) / 中华显微外科杂志

Objective:To sort out the history of microsurgery in China from 1960 to 1973 based on the literatures in chronological order.Methods:Chinese and English scientific journals and academic monographs published in public and in house were searched, and the words "microsurgery" and "microsurgery related" literatures in both Chinese and English were carefully read and analysed. The dates of operation, communication and report were recorded and confirmed.Results:Microsurgery in China started in early 1963, thanks to the report of the world's first successful severed limb replantation in Shanghai Sixth Hospital. In the following 3 years, many teams carried out experimental researches on microvascular technology and explored the replantation of severed fingers. In 1964, the world's first severed leg replantation. In 1966, the world's first toe transfer was operated to reconstruct the thumb, and the world's first batch of completely severed fingers were successfully replanted by microvascular suture. In 1972, it was reported, at the Guangzhou Conference on Replantation of Severed Limbs, that a 44.9% of survival rate had been achieved over 260 cases and the term "microsurgery" was used for the first time in the conference. In March, 1973, the second free inguinal flap transfer in the world was completed. In May, 1973, an American Replantation Mission visited China. It opened a precedent for academic exchange in microsurgery between China and foreign countries. With 10 years of clinical practices, the original and advanced Chinese limb (finger) replantation technology and principle had been recognised by the international peers.Conclusion:The research on the history of Chinese microsurgery has confirmed that the development of Chinese microsurgery was basically synchronised with the world, but with a difficult start in 1960-1973.
