1广东龙窝花岗闪长质岩体的年代学、地球化学及岩石成因显示文摘龙窝岩体是南岭地区燕山早期具幔源组分贡献的花岗岩的典型代表,其主体岩性为花岗闪长岩,岩体中含有深色闪长质包体,锆石ELA-ICP-MS定年结果表明花岗闪长岩的形成年龄为169.1±2.5Ma,属中侏罗世岩浆活动的产物。地球化学特征上,该岩体铝弱过饱和(A/NKC=1.0~1.1),相对贫碱,富钾(K_2O/Na_2O=1.15~1.45),富轻稀土和大离子亲石元素(如Rb、Cs、Th、U),贫高场强元素(如Nb、Ti)。闪长质包体具有与寄主岩相似的矿物组合,但铁镁矿物含量及过渡族元素(V、CR、Co、Ni)丰度相对偏高,二者的主量和微量元素表现出混合成因的演化趋势。寄主岩与包体具有相近的Sr、Nd同位素组成,I_(Sr)和ε_(Nd)(t)值分别为0.70843~0.70995、-6.53~-8.89和0.70797~0.70882、-4.71~-9.24,均表现出壳幔混源花岗岩类岩石的特点。二元混合模拟计算显示寄主岩与包体成岩过程中地幔物质的混入比例分别为32.9%~40.4%和 31.8%~46.4%。通过对岩石产出构造背景及地质地球化学特征的综合分析,表明龙窝花岗闪长岩及其中的闪长质包体是在伸展-引张环境下,由幔源基性岩浆及其诱发的壳源长英质岩浆混合作用的产物。邱检生 胡建 McInnes B I A 蒋少涌 徐夕生 Allen C M 2004岩石学报2004,20,6:19

3滋养细胞组织 GATA-3表达:445例免疫组化及其诊断应用分析显示文摘GATA-3主要表达在乳腺癌和尿路上皮癌,而在正常或病变滋养细胞组织中的表达报道甚少。作者选取445例正常/病变滋养细胞组织及其肿瘤进行 GATA-3免疫组化评估,根据着色强弱标记为(-~-),探讨GATA-3在下列组织中的表达意义。这些组织包括孕囊/中晚期妊娠胎盘/异位妊娠、葡萄胎、胎盘结节、正常/异常植入部位、绒毛膜癌、上皮样滋养细胞肿瘤、胎盘滋养细胞肿瘤、非典型平滑肌瘤(含平滑肌肉瘤)、子宫颈和肺的鳞状细胞癌。Natalie B Allen M G Ie-Ming S 许文静 余英豪 2015临床与实验病理学杂志2015,31,9:11
