AIM:To investigate the long-term effect of the number of resected lymph nodes (LNs) on the prognosis of patients with node-negative gastric ***: Clinical data of 211 patients with gastric cancer, without nodal involvement, were analyzed retrospectively after D2 radical operation. We analyzed the relationship between the number of resected LNs with the 5-year survival, the recurrence rate and the post-operative complication ***: The 5-year survival of the entire cohort was 82.2%. The total number of dissected LNs was one of the independent prognostic factors. Among patients with comparable depth of invasion, the larger the number of resected LNs, the better the survival (P0.01). The post-operative complication rate was 10.9% and was not signif icantly correlated with the number of dissected LNs (P>0.05).CONCLUSION: For node-negative gastric cancer, sufficient number of dissected LNs is recommended during D2 lymphadenectomy, to improve the long-term survival and reduce the recurrence. Suitable increments of the dissected LN count would not increase the post-operative complication rate.

为提高版图电路提取效率，提出了一种新的层次式版图电路提取方法．该算法首先对版图进行纵横分析确定各单元的调用类型，并找出单元之间的重叠．然后在单元提取中，取出单元与外界的连接关系，并把这种连接关系映射到上级单元，以进行上级单元的提取．实验结果表明，该算法能有效地处理版图单元之间的任意重叠，包括各种复杂重叠，如多单元重叠以及产生或删除单元晶体管的重叠，同时，它能在有限的内存下提取较大规模的电路．与打散提取相比，在单元重复调用次数较多时，能明显地减少提取时间．

提出了一种面向SOC平台的高效H.264解码架,通过解码和去块效应的宏块级流水线化处理,解决了视频流支持灵活的宏块排序(FMO)和任意条带顺序(ASO)技术时码流内的宏块次序与去块效应操作中要求的光栅扫描顺序不同的矛盾,更有利于硬件实现。在硬件设计中,采用cache缓存法暂存用于去块效应的临时数据,同时采用双并行总线满足较高的系统带宽要求。FPGA和SOC的实现结果表明,在系统时钟为166 MHz时,设计结果完全满足1080HD(1920×1088@30 fps)的解码要求。
