Evaluation of sensory function and recovery after replantation of fingertips at ZoneⅠin children

Sensory function is the most significant criterion when evaluating the prognosis of replanted fingers. Current clinical research has focused on surgical techniques and indications for finger replantation; however, few studies have focused on recovery of finger sensory function af- ter replantation. This study retrospectively assessed data of eight patients who had undergone nine Zone I replantations of the fingertips in the First Affiliated Hospital of Sun Yat-sen University of China from July 2014 to January 2016. Variations in the extent of damage, with the residual vessels or nerves in some fingers being too short or even missing, prevented tension-free suture repair in some patients. Thus, re- pair of four of the nine fingertips included arteriovenous anastomosis, the remaining five undergoing arterial anastomosis during replanta- tion of the amputated fingers. Three patients underwent nerve repair, whereas the remaining six cases did not. Fingertip replantations were successful in all eight patients. Compared with the patients without vascular anastomosis, no obvious atrophy was visible in the fingertips of patients who did undergo vascular anastomosis during replantation and their sensory function did recover. Fingertip replantation pro- vides good sensory function and cosmetic outcomes when good artery and vein anastomoses have been created, even when digital nerves have not been repaired.

针对研究开发的四边形折流式膜生物流化床,构建了气、固、液三相流可视化平台,应用取样法和激光粒子图像测速(PIV)技术剖析了不同进水流量和曝气强度组合对流化床内的填料浓度及液相流场特性的影响.结果表明,折流板上部形成的曝气死区,提高了升流区的填料浓度;折流板和导流锥形成的进水角度使流场冲击反应器底部的填料,提高了在低曝气强度下流化床的填料浓度,在实际运行过程可降低曝气能耗;四边形折流式膜生物流化床的结构特点导致填料与膜组件相互碰撞的概率增大,强化了膜污染的控制.曝气强度和进水流量的变化改变了液相的轴向返混强度和剪切力,进而改变了填料浓度,使气、固、液三相冲刷膜组件的作用增大,最终影响膜面传质系数和浓差极化边界层厚度,降低了膜污染.通过流化床结构的改变提高填料浓度和改善流场特性,为高浓度有机废水好氧生物的处理提供了一个研究方向.

Journal of Hydrodynamics 2006年第2期18卷 237-242页

作者： ZHANG Shu-tao wang Dao-zeng Department of Mathematics College of Science China Jiliang University Hangzhou 310018 China Shanghai Institute of Applied Mathematics and Mechanics Shanghai University Shanghai 200072 China

By using the high-efficiency of four-stage calculation method named ＂channel-junction-channel＂ and considering the influence of temporal and spatial variation of aquatic environmental capacity, an optimization method of aquatic environmental capacity for tidal river network was worked out. The method not only reflects characteristics of unsteady flow with variable directions, but also indicates that aquatic environmental capacity is influenced by boundary condition and water quality standard, etc. It has been applied to the regional program of Pudong area in Shanghai, and the computed results agree well with the practical data.
