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

4持续血糖监测用于检测危重症患儿高血糖的前瞻性研完显示文摘目的用组织间隙持续血糖监测仪评价PICU非糖尿病患儿血糖增高程度,并与实验室间断检测血糖的方法比较,评价监测效果。设计前瞻性、观察性研究。场所西马萨诸塞州一所医学中心拥有10张床位的PICU。对象20名非糖尿病患儿,年龄1~18岁,预计需要2d以上的重症监护。干预在患儿皮下放置持续血糖监测仪,征得患儿及家属同意后,另接探头进行72h连续血糖监测并与实验室所测血糖水平进行比较。测量指标和主要结果平均每位患儿持续监测685.2h,共有16337次探头读数,43.0%读数高于125mg/dl(6.9mmol/L),27.2%高于140mg/dl(7.8mmol/L),4%高于200mg/dl(11.1mmol/L)。实验室血糖值提示升高的频度不如持续监测,且易错过血糖升高的关键时段。结论PICU患儿可出现显著血糖升高,实验室间断检测血糖可能低估此现象。Allen HF Rake A Roy M 2008中国小儿急救医学2008,15,2:2
