有学者认为内蒙古和林格尔县土城子征集的“耳铸公剑”铭铜剑为春秋晋国公子重耳（晋文公）所用之剑。本文从“耳铸公剑”铭铜剑的形制、吴越系厚格剑在北方地区的传播、战国时期该型剑厚格的变化等几个方面论述，认为该剑年代应不早于... 详细信息

有学者认为内蒙古和林格尔县土城子征集的“耳铸公剑”铭铜剑为春秋晋国公子重耳（晋文公）所用之剑。本文从“耳铸公剑”铭铜剑的形制、吴越系厚格剑在北方地区的传播、战国时期该型剑厚格的变化等几个方面论述，认为该剑年代应不早于春秋晚期，很可能为战国时期，并指出该剑与晋国公子重耳（晋文公）无涉。

目的:探讨乳腺癌治疗前多模态MRI联合血清miR-125b水平预测新辅助化疗疗效的价值。方法:研究对象为于我院首次接受全程新辅助化疗并行手术切除治疗的90例女性乳腺癌患者。治疗前对患者进行乳腺MRI检查,记录病灶直径、边缘、形状、平扫T_(2)WI图像上病灶内是否高信号和时间信号强度曲线(TIC)类型、表观扩散系数(ADC)、单纯扩散系数(D)、伪扩散系数(D*)及灌注分数(f)。依据Miller-Payne分级标准对病理学反应进行评估,分为病理反应不佳(NR)组和病理反应良好(R)组。结果:乳腺癌患者新辅助化疗后R组52例(57.78%),NR组38例(42.22%),两组的年龄、临床分期、病理类型、雌激素受体(er)、孕激素受体(PR)和人表皮生长因子受体2(Her2)表达水平差异无统计学意义(P>0.05)。R组中Ki-67>14%的比例显著高于NR组(P0.05)。R组的TIC类型为Ⅲ型的比例显著高于NR组,ADC值显著低于NR组,f值显著高于NR组(P<0.05)。R组的血清miR-125b相对表达量显著低于NR组(t=-11.007,P<0.001)。二元Logistic回归分析结果显示,较高的ADC值、血清miR-125b水平和较低的f值是乳腺癌新辅助化疗后疗效为NR的独立危险因素(P<0.05)。ADC值、f值、血清miR-125b水平及三者联合预测乳腺癌新辅助化疗疗效的AUC分别为0.863(95%CI:0.799~0.927,P<0.001)、0.819(95%CI:0.744~0.893,P<0.001)、0.832(95%CI:0.755~0.908,P<0.001)和0.958(95%CI:0.929~0.988,P<0.001)。结论:治疗前多模态MRI联合血清miR-125b水平对乳腺癌患者新辅助化疗疗效具有一定的预测价值。

Recently, significant oil discoveries have been made in the shallower pay zones of the Jurassic Badaowan Formation (J_(1)b) in the Mahu Sag, Junggar Basin, Northwest China. However, little work has been done on the geochemical characteristics and origins of the oil in the J_(1)b reservoir. This study analyzes 44 oil and 14 source rock samples from the area in order to reveal their organic geochemical characteristics and the origins of the oils. The J_(1)b oils are characterized by a low Pr/Ph ratio and high β-carotene and gammacerane indices, which indicate that they were mainly generated from source rocks deposited in a hypersaline environment. The oils are also extremely enhanced in C_(29) regular steranes, possibly derived from halophilic algae. Oil-source correlation shows that the oils were derived from the Lower Permian Fengcheng Formation (P_(1)f) source rocks, which were deposited in a strongly stratified and highly saline water column with a predominance of algal/bacterial input in the organic matter. The source rocks of the Middle Permian lower-Wuerhe Formation (P_(2)w), which were deposited in fresh to slightly saline water conditions with a greater input of terrigenous organic matter, make only a minor contribution to the J_(1)b oils. The reconstruction of the oil accumulation process shows that the J_(1)b oil reservoir may have been twice charged during Late Jurassic–Early Cretaceous and the Paleogene–Neogene, respectively. A large amount volume of hydrocarbons generated in the P_(1)f source rock and leaked from T_(1)b oil reservoirs migrated along faults connecting source beds and shallow-buried secondary faults into Jurassic traps, resulting in large-scale accumulations in J_(1)b. These results are crucial for understanding the petroleum system of the Mahu Sag and will provide valuable guidance for petroleum exploration in the shallower formations in the slope area of the sag.

磷(P)是长江流域备受关注的污染物。乌江是长江八大支流之一,位于三峡水库近库尾江段。武隆断面是乌江入长江控制断面。对1998-2019时期武隆断面径流量、悬浮泥沙浓度(SS)与输沙量、磷浓度与通量(包括总磷(TP)、溶解态磷(DP)和颗粒态磷(PP))年际变化及季节特征进行研究,并基于河流基流分割原理对磷的来源进行了解析。结果表明,(1)1998-2019年,乌江武隆断面径流量在一定幅度内上下波动,而悬浮泥沙浓度和输沙量下降剧烈。(2)22年来,乌江TP和DP浓度与通量总体上呈先升高后下降的趋势,2009-2013年为磷污染峰值期,TP和DP浓度与通量远高于其它时期。(3)2007年是一个重要的时间节点,该节点前,TP的赋存形态以颗粒态为主,颗粒态磷在总磷中的占比均值为65%;该节点后,TP的赋存形态转变为以溶解态为主,颗粒态磷占比均值下降为16%,相应地,溶解态磷占比由35%上升为84%。水沙条件改变是磷形态发生显著变化的主要驱动力,磷污染程度亦是磷形态变化的重要影响因素。(4)磷通量在年内的季节分布发生了显著变化,丰水期磷通量减少,枯水期磷通量增加。(5)1998-2012、2009-2013和2014-2019年3个时期点源负荷占比分别为23.5%、36.8%和62.1%,呈增加趋势。(6)建议制定适宜的总磷控制目标,结合目前所存在的磷污染风险点,进一步强化监管,侧重源头治理。
