1在结肠和直肠的癌症的淋巴节点收获: 当前的考虑显示文摘 The prognostic significance of identifying lymph node(LN) metastases following surgical resection for colon and rectal cancer is well recognized and is reflected in accurate staging of the disease.An established body of evidence exists,demonstrating an association between a higher total LN count and improved survival,particularly for node negative colon cancer.In node positive disease,however,the lymph node ratios may represent a better prognostic indicator,although the impact of this on clinical treatment has yet to be universally established.By extension,strategies to increase surgical node harvest and/or laboratory methods to increase LN yield seem logical and might improve cancer staging.However,debate prevails as to whether or not these extrapolations are clinically relevant,particularly when very high LN counts are sought.Current guidelines recommend a minimum of 12 nodes harvested as the standard of care,yet the evidence for such is questionable as it is unclear whether an increasing the LN count results in improved survival.Findings from modern treatments,including down-staging in rectal cancer using pre-operative chemoradiotherapy,paradoxically suggest that lower LN count,or indeed complete absence of LNs,are associated with improved survival;implying that using a specific number of LNs harvested as a measure of surgical quality is not always appropriate.The pursuit of a sufficient LN harvest represents good clinical practice;however,recent evidence shows that the exhaustive searching for very high LN yields may be unnecessary and has little in? uence on modern approaches to treatment.James R McDonald Andrew G Renehan Sarah T O’Dwyer Najib Y Haboubi 2012World Journal of Gastrointestinal Surgery2012,4,1:8
2建立土蜂资源保护区控制蛴螬为害显示文摘1997~2001年,在山东省莱阳市、海阳市和日照市建立土蜂保护区3处,设定土蜂、蛴螬观察点9个,相同类型的对照区3个。在保护区内实行禁止施用农药、种植蜜源植物、人为储存蜂茧越冬等对土蜂资源的各项保护措施。研究表明,保护区对土蜂起到了显著的保护作用。保护区内的农田土蜂成虫数量由平均0.23头/100网升至3.62头/100网,土蜂茧数量由0.35粒/m2升至1.46粒/m2,土蜂对蛴螬的寄生率也有显著提高,蛴螬数量由3.74头/m2降至0.62头/m2。陈红印 陈长风 王树英 刘崇林 宋文鹏 姜祖诚 罗益镇 McDonald R C 2003植保技术与推广2003,23,7:8
