彩色多普勒超声在动态监测移植肝及其并发症中的应用

目的探讨彩色多普勒超声在动态监测肝移植术后血流动力学变化及并发症诊治中的应用价值。方法回顾我中心107例原位肝移植术后应用彩色多普勒超声资料,汇总后行统计学分析。结果肝移植术后早期门脉流速较正常对照组升高,而肝动脉流速降低,后逐渐恢复正常。107例中发现肝动脉血栓形成2例(1.87%),肝动脉狭窄5例(4.67%),门脉血栓形成3例(2.80%),肿瘤复发7例(6.54%),诊断为急性排斥反应18例次(16.82%),慢性排斥反应10例次(9.34%),胸腔积液105例(98.13%),腹腔积液65例(60.74%),假性动脉瘤1例,胰漏1例,胆道感染4例(3.74%),胆道狭窄4例(3.74%),胆漏5例(4.67%),胆总管结石1例。结论彩色多普勒超声在动态监测肝移植术后血流动力学变化及并发症诊治中具有重要的临床意义。

Why is the southwest the most productive region of the East Sea/Sea of Japan?

The East Sea/Sea of Japan is a moderately productive sea that supports a wealth of living marine resources. Of the East Sea subregions, the southwest has the highest productivity. Various authors have proposed coastal upwelling, the Tsushima Current, the Changjiang Dilute Water, eddies, or discharge from the Nagdong River as potential sources of additional nutrients. In this paper, we propose, using satellite data from 1998 to 2006, that the biological productivity of the southwestern region is enhanced mainly by wind-driven upwelling along the Korean coast. Firstly, the climatology of seasonal patterns suggests that the enhanced chlorophyll a along the Korean coast is of local origin. Secondly, coastal upwelling is frequent in all seasons except winter. For example, along the coast of the Ulgi region, enhanced chlorophyll a due to coastal upwelling was observed for 25–92% of the time between Jun and Sep in the period 1998–2006. Thirdly, the advection of upwelled water through various pathways to the deeper basin was observed. Fourthly, there appeared to be a strong correlation between the interannual chlorophyll a variations of the coastal upwelling regions and the Ulleung Basin. The chlorophyll a patterns of both regions were closely related to the wind pattern in the upwelling regions, but not to that in the Ulleung Basin. Finally, changes in advection pathways also appeared to affect the productivity of the Ulleung Basin. Since 2004, there has been a shift in the pathways of upwelled water, and consequent increases in chlorophyll a in the Ulleung Basin were observed. This last observation requires further investigation.
