为进一步揭示汞在松花江沉积物表面的环境行为,通过模拟实验,研究粒级、pH和溶解性有机质(DOM)对汞在松花江沉积物表面吸附-解吸量的影响.结果表明,不同粒级沉积物的吸附能力差别较大,本实验条件下,沉积物粒级越小,其吸附能力越强.在各种浓度的实验设计组中均有:pH由3.5升高至4.5时,吸附量增加,当pH>4.5时,随pH的继续升高吸附量开始降低;沉积物中汞的解吸量随pH的增加呈先下降后上升的趋势变化,各体系的最小值均出现在pH5.柠檬酸对沉积物吸附汞的影响以抑制作用为主,其抑制作用强度与吸附体系中汞浓度有关;柠檬酸对解吸量的影响也比较明显,随着柠檬酸浓度的增加,对沉积物中汞解吸作用的影响表现为促进-抑制-稳定的变化趋势.因此,以上因素对汞在沉积物表面吸附-解吸的影响较大,在进行河流汞污染控制及突发污染事件处理时,有必要充分考虑以上因素的影响.

The sequence of the rice genome holds fundamental information for its biology, including physiology, genetics, development, and evolution, as well as information on many beneficial phenotypes of economic significance. Using a "whole genome shotgun" approach, we have pro-duced a draft rice genome sequence of Oryza sativa ssp. in-dica, the major crop rice subspecies in China and many other regions of Asia. The draft genome sequence is constructed from over 4.3 million successful sequencing traces with an accumulative total length of 2214.9 Mb. The initial assembly of the non-redundant sequences reached 409.76 Mb in length, based on 3.30 million successful sequencing traces with a total length of 1797.4 Mb from an indica variant cultivar 93-11, giving an estimated coverage of 95.29% of the rice genome with an average base accuracy of higher than 99%. The coverage of the draft sequence, the randomness of the sequence distribution, and the consistency of BIG-ASSEM-BLER, a custom-designed software package

目的分析^18FDG PET-CT诊断食管癌淋巴结转移的优势及确定淋巴结放疗靶区的可行性。方法回顾性分析30例食管癌患者的临床病理资料，分析PET-CT在诊断淋巴结转移方面的优势，基于CT和PET-CT确定淋巴结大体肿瘤靶区（GTVN）和临床靶区（CTVN），根据术后病理分析PET-CT在确定淋巴结放疗靶区中的价值。结果13例由CT确定的GTVN（GTVN-CT）与病理一致，19例基于PET-CT的GTVN（GTVN-PET-CT）与病理相符。对照淋巴结病理结果，PET-CT改变了15例由CT确定的GTVN和其中10例的CTVN。PET-CT导致GTV缩小（GTVN-PET-CT＜GTVN-CT）的3例共涉及3组淋巴结，其中1例临床靶区缩小（CTVN-PET-CT＜CTVN-CT）；GTVN-PET-CT＞GTVN-CT的12例共涉及22组淋巴结，其中9例CTVN亦扩大。GTVN-PET-CT＞GTVN-CT的亚组分析显示，PET-CT确定的淋巴结GTV准确率高于CT（67％：25％，P=0．041）。结论PET-CT在诊断淋巴结转移中的优势使之可作为优化和确定食管癌淋巴结放疗靶区的有用工具。
