围绕国家战略性产业发展对稀土资源的需求,特别是紧缺的重稀土资源,如何快速有效地发现富含重稀土矿床找矿靶区是勘查地球化学急需解决的问题。“化学地球”大科学计划获得全国地球化学基准数据,圈定稀土异常超常富集区9处,其中新发现的滇南红河州蒙自—中越边境地区稀土富集区轻重稀土比值(LREE/HREE)为3.5,与华南富含重稀土的离子吸附型稀土矿异常LREE/HREE比值一致。结合地质背景、成矿母岩、气候和地形地貌特点等初步判断具有寻找类似华南富含重稀土的离子吸附型稀土矿资源潜力。因此,对这一异常的核心区,开展了1:25万、1:5万地球化学调查和风化剖面测量,并经29个钻孔验证,初步发现马鞍底潜在超大型富含重稀土离子吸附型稀土矿。富矿区分布于坡度较缓的坡脚处,风化母岩为印支期和燕山期花岗岩、元古界斜长片麻岩和变粒岩。风化剖面厚度最深可达25 m左右,富矿层位位于全风化层,一般在2~13m深度,矿体平均厚度6~13m,最厚可达21m,平均品位0.14%。根据29个钻孔和84个风化壳剖面测量,初步估算稀土潜在矿石量约9.46亿吨、稀土氧化物潜在资源约100万吨。这是我国首次在滇南地区发现潜在超大型离子吸附型稀土矿。该离子吸附型稀土矿同时富含轻稀土(镧、铈、镨、钕)和重稀土(钆、铽、镝、钇),具有重大经济价值和科学意义。这一发现表明开展从极低密度、低密度到高密度地球化学调查,获得全部16个稀土元素高质量数据是发现离子吸附型稀土矿的快速有效方法。

2005年是中国承诺碳减排目标的基准年份,因而也是中国城市碳减排战略制定和近中期低碳转型的基准年份和对照年份。中国城市2005年CO_2排放数据的一致性、全面性和精准性对于中国所有城市和每个具体城市的目标考核和评估都有重要意义。基于中国高空间分辨率网格数据(CHRED 2.0)、城市层面统计数据以及大量现场调研和走访,建立2005年中国城市CO_2排放数据集,包括工业能源排放、工业过程排放、农业排放、服务业排放、城镇生活排放、农村生活排放、交通排放7个部门的直接排放数据和间接排放数据。该数据集的建立汇总了86名研究人员的工作成果,在企业、城市不同行业与部门、城市工业和城市总化石能源等不同层面进行了大量的交叉验证和数据分析,有效保障了数据的精确性和准确性。结果显示,2005年中国城市碳排放呈现出较大的体量差异和空间格局差异。排放前10的城市几乎比排放后10的城市的排放量高出两个数量级。高排放城市基本都是城市群的核心城市。东部城市直接排放占全国直接排放比例最高,达到44.59%,其次是西部城市21.76%,中部城市22.70%,东北城市10.95%。

目的了解2017年上海市细菌耐药性监测结果。方法采用纸片扩散法或自动化仪器法对上海市49所医院的临床分离菌进行药敏试验。包括30所三级医院(含3所儿童医院)和19所二级医院。采用美国临床和实验室标准化协会(CLsi)2017年版标准判断结果。结果共获134078株临床分离菌,其中革兰阳性菌40243株,占30.0%;革兰阴性菌93835株,占70.0%。二级医院和三级医院菌株分别占29.0%和71.0%。在二、三级医院中革兰阳性菌和革兰阴性菌各为25.4%和74.6%、31.9%和68.1%。MRSA和MRCNS在各自菌种中的检出率分别为49.1%和79.7%。二级医院、三级医院的MRSA和MRCNS检出率分别为53.2%和72.1%、47.7%和82.2%。葡萄球菌属中未发现万古霉素耐药株。1041株儿童非脑膜炎肺炎链球菌分离株中青霉素敏感(PSSP)、中介(PISP)和耐药株(PRSP)分别占84.3%、7.8%和7.9%;330株成人分离株PSSP、PISP和PRSP分别为89.4%、4.2%和6.4%。检出5株(0.1%)万古霉素耐药粪肠球菌、64株(1.2%)万古霉素耐药屎肠球菌,经过PCR测序确认的菌株中主要为vanA基因型。大肠埃希菌、肺炎克雷伯菌和奇异变形杆菌中ESBL的检出率分别为54.9%、35.1%和47.6%。上述产ESBL菌株在二级医院和三级医院的检出率分别为53.7%、31.5%、44.0%和55.5%、37.0%、50.0%。肠杆菌科细菌对碳青霉烯类抗生素仍高度敏感,对亚胺培南和美罗培南的总耐药率分别为11.1%和11.0%,二级医院、三级医院分别为9.0%和9.2%、12.2%和11.9%,碳青霉烯类耐药肠杆菌科细菌(CRE)的检出率为11.9%,其中73.4%是肺炎克雷伯菌。鲍曼不动杆菌、肺炎克雷伯菌、铜绿假单胞菌和大肠埃希菌中出现对大多数测试药物耐药而仅对1～2种抗菌药物敏感的广泛耐药株,二级医院和三级医院分别为64株、357株、7株、25株和412株、1129株、38株、45株。结论目前主要临床分离菌对于常用抗菌药物的耐药性仍甚为严重,尤其是多重耐药的革兰阴性杆菌,对人类健康构成严重威胁,需引起高度重视并采取有效措施防治耐药菌感染。
