富血小板血浆制剂中白细胞在临床中的作用及其制备

自体富血小板血浆(platelet-rich plasma,PRP)是自体血液经离心分离得到的高浓度血小板的浓聚物。PRP中含有高浓度自体来源的生长因子,包括血管内皮生长因子、血小板来源生长因子、转化生长因子-β等。在临床中,对抗炎及组织修复具有促进作用,且PRP制备简便、费用相对较低、安全性较高,因此应用越来越广泛。自体PRP可能会含有一定数量的白细胞。目前对于白细胞在PRP制剂中所发挥的作用及影响仍存在争议,PRP中是否应包含白细胞仍缺乏统一的共识及可靠的临床指南。本文将对PRP中白细胞的临床作用、PRP的制备及储存标准进行综述,从而为临床提供一定的参考及理论基础。

Self-contained in situ sediment acoustic measurement system based on hydraulic driving penetration

A novel self-contained in situ sediment acoustic measurement system based on hydraulic driving penetration is proposed to solve the problem of large disturbances to sediments of the in situ equipments already in existence. By using a hydraulic driving device, the system drives four acoustic probes into sediments at an even speed, and this decreases disturbances to sediments introduced by the penetration of acoustic probes. By means of the special design of the central control unit, the system can work full-automatically and the data are stored self-containedly, and this avoids the requirement of real-time remote controlling from the ship. Its operating water depth, measuring depth and measuring frequency is 500m, 1.0m and 30kHz respectively. A set of in situ sound speeds and attenuation coefficients of sediments are obtained at 40 stations using the system. The results confirm that the data obtained by the in situ sediment acoustic system are accurate and credible.
