| 1 | 激光剥蚀信号在线平滑和去汞装置:原位微区铅同位素准确分析利器显示文摘激光原位微区分析可在微观尺度上完成样品的元素定量分析或同位素组成测定,为研究成岩、成矿物质来源和追踪地壳与地幔演化历史提供了独特的观察视野。但是,激光剥蚀等离子体质谱的一些缺陷阻碍了地质样品的高精度、高空间分辨率分析,比如:剥蚀池的位置效应、低剥蚀速率下信号波动影响、激光剥蚀脉动式信号导致的光谱螺纹效应、高频激光剥蚀造成的元素分馏效应等。为此,一些学者设计了不同规格和样式的激光剥蚀信号平滑装置来克服这些问题。但是,这些信号平滑装置普遍还存在气体吹扫时间过长和降低激光剥蚀信号灵敏度等问题。因此,研制新型的信号平滑装置对改善LA—ICP—MS的数据质量具有重要的意义。 | Hu Z Zhang W Liu Y Gao S Li M Zong K Chen H Hu S 刘勇胜 | 2015 | 矿物岩石地球化学通报2015，34，4： | 114 |
| 2 | Oncofetal antigen glypican-3 as a promising early diagnostic marker for hepatocellular carcinoma显示文摘BACKGROUND:Hepatocellular carcinoma (HCC) is characterized by a multi-cause,multi-stage and multi-focus process of tumor progression.Its prognosis is poor and early diagnosis is of utmost importance.This study was undertaken to investigate the dynamic expression of oncofetal antigen glypican-3 (GPC-3) and GPC-3 mRNA in hepatocarcinogenesis and to explore their early diagnostic value for HCC.METHODS:A hepatoma model was induced in male Sprague-Dawley rats with 0.05% 2-fluorenylacetamide and confirmed by hematoxylin and eosin staining and gamma-glutamyltransferase (GGT) expression.Total RNA was purified and transcribed into cDNA by reverse transcription.Fragments of the GPC-3 gene were amplified by nested RT-PCR,and confirmed by sequencing.GPC-3 was analyzed by immunohistochemistry,Western blotting or ELISA.RESULTS:Positive GPC-3 expression showed as brown granule-like staining localized in the cytoplasm.Histological examination of hepatocytes revealed three morphological stages of granule-like degeneration,atypical hyperplasia (precancerous),and cancer formation,with a progressive increase of liver total RNA and GGT expression.The incidence of liver GPC-3 mRNA and GPC-3,and serum GPC-3 was 100%,100% and 77.8% in the HCC group,100%,100%,and 66.7% in the precancerous group,83.3%,83.3%,and 38.9% in the degeneration group,and no expression in the liver or blood of the control group,respectively.There was a positive correlation between liver GPC-3 mRNA and total RNA level (r=0.475,P<0.05) or liver GPC-3 (r=1.0,P<0.001) or serum GPC-3 (r= 0.994,P<0.001).CONCLUSION:Abnormal oncofetal antigen GPC-3 and GPC-3 mRNA expression in hepatocarcinogenesis may be promising molecular markers for early diagnosis of HCC. | Research Center of Clinical Medicine,Affiliated Hospital of Nantong University,Nantong 226001,China (Yao M,Yao DF,Qiu LW,Wu W,Sai WL,Yang JL and Zhang HJ) Department of Oncology,Yancheng First People’s Hospital,Yancheng 224001,China (Bian YZ) Department of Oncology,Second Affiliated Hospital,Nanjing Medical University,Nanjing 210011,China (Zhang CG) | 2011 | Hepatobiliary & Pancreatic Diseases International2011，10，3： | 51 |

| 5 | On the Application of PCA Technique to Fault Diagnosis显示文摘In this paper, we briefly address the application of the standard principal component analysis (PCA) technique to fault detection and identification. Based on an analysis of the existing test statistic, we propose a new test statistic, which is similar to the Hawkin’s TH 2 statistic but without the numerical drawback. In comparison with the SPE index, the threshold setting associated with the new statistic is computationally simpler. Our further study is dedicated to the analysis of fault sensitivity. We consider the off-set and scaling faults, and evaluate the test statistic by viewing its sensitivity to the faults. Our final study focuses on identifying off-set and scaling faults. To this end, two algorithms are proposed. This paper also includes some critical remarks on the application of the PCA technique to fault diagnosis. | DING S ZHANG P DING E YIN S Naik A DENG P GUI W | 2010 | Tsinghua Science and Technology2010，15，2： | 31 |

| 7 | SHRIMP U-Pb dating for a K-bentonite bed in the Tieling Formation,North China显示文摘A SHRIMP U-Pb zircon age of 1437±21 Ma was obtained for a recently discovered K-bentonite bed in the Tieling Formation,situated northeast of Beijing at the boundary between Liaoning and Hebei provinces,on the northern margin of the North China Craton(NCC).The SHRIMP U-Pb age places Tieling Formation near the end of the Calymmian Period of the early Mesoproterozoic Era.In addition,a SHRIMP U-Pb zircon date of 1372±18 Ma was acquired for K-bentonite beds in the overlying,dark-shale-dominated Xiamaling Formation from the same location northeast of Beijing.This date assigns a similar Mid-Mesoproterozoic(Ectasian Period) age for the Xiamaling Formation,as have previously determined dates from other sections northwest of Beijing.These dates indicate that the Tieling and Xiamaling formations,as well as the related succession in the eastern part of the Yanshan Mountains,represented by the well-known Meso-to Neoproterozoic standard section in Jixian,can be correlated well with sections northwest of Beijing in the western part of the Yanshan Mountains.In other words,the boundary between the Calymmian and Ectasian periods in the northern parts of the NCC is marked by the unconformity between the Tieling and Xiamaling formations in the northern NCC.This boundary was previously ascribed to the 'Qinyu Orogeny' and thought to be of Grenville age.In this regard,the conventional 'Qinyu Orogeny' should now be regarded as a short-lived regional uplift during Early Mesoproterozoic time,rather than a result from the Grenvillian assembly of the NCC to the Rodinia Supercontinent(~1.0 Ga). | SU WenBo LI HuaiKun HUFF W D ETTENSOHN F R ZHANG ShiHong ZHOU HongYing WAN YuSheng | 2010 | Chinese Science Bulletin2010，55，29： | 30 |

| 9 | 国际骨关节炎研究学会髋与膝骨关节炎治疗指南——第一部分:对现有治疗指南的严格评价及对近期研究依据的系统回顾显示文摘目的为制定一个可持续更新、基于循证医学和国际共识的髋、膝骨关节炎(OA)治疗指南,国际骨关节炎研究学会(OARSI)进行了一系列前期工作——对现有治疗指南进行严格评价及对近期研究依据进行系统性回顾。方法来自相关领域的16位专家(涵盖两大洲6个国家)组成该治疗指南研究小组,并邀请3位评价非英语文献的专家。在MEDLINE、EMBASE、SCI、CINAHL、AMED、Cochrane Library数据库,7个治疗指南网站以及Google上系统性检索OA治疗指南,4个由4人组成的评审小组对符合纳入及排除标准的治疗指南采用指南研究与评价评审表(AGREE)法进行评估,并对其适用范围、利益相关人员是否参与研究、严谨性、叙述是否清楚、可行性、编写的独立性以及总体质量进行百分制打分,对指南中论述及推荐的疗法加以总结。对每一种疗法的循证依据均经系统性回顾(2002年1月至2006年1月)进行更新。采用专门针对系统性回顾和随机对照研究评估的Oxman-Guyatt和Jadad方法,对各个循证依据分别在可能性、效能、需治疗数、相关风险、优势比、生活质量调整寿命年(QALY)费用等方面进行评分。结果一共检索到1462个治疗指南,其中23个符合纳入/排除标准。基于专家意见,或循证依据,或两者皆有的得分,分别为28%、41%和51% (P=0.001)。各方面评分从指南质量的18%到指南应用范围的67%不等。其中13个治疗指南已成为特定方面的治疗指南,包括5个用于初级护理、3个用于风湿病学、3个用于理疗、2个用于骨伤学,而有10个可普遍应用。同时,有14个治疗指南没有特别针对髋关节或膝关节,8个则专用于膝关节,只有1个专用于髋关节。在这些指南中涉及到51种不同的疗法,但只有20种被广泛推广应用。2002年1月至2006年发表的随机对照研究结果验证了一些疗法的有效性,如锻炼、有氧训练、水疗、非类固醇类消炎镇痛药(NSAID)等。近期不能确定其有效性的疗法有超声、推拿、冷热敷。这些疗法的不良反应也是各有不同。非选择性NSAID类药物的胃肠道风险及罗非昔布增加心肌梗死风险的证据均再次证实。其他药物潜在的相关不良反应,目前还尚无定论。结论现有的23个OA治疗指南中有单纯源于专家观点的,也有源于循证研究或两者兼具的。51种疗法中有20种得到这些指南的广泛认同。上述表明现时仍存在着单纯源于专家建议的疗法;对现有治疗指南严格评价后发现,其总体质量不是很理想;广泛认可的疗法可能没有相关循证研究依据的支持。理想的OA治疗指南应将专家普遍的认可和循证研究依据的支持统一起来,并在其编写的独立性、应用的风险性及优越性等问题上有所侧重。通过这次对现有OA治疗指南的回顾,我们认识到现有的这些指南中存在一些不足。在今后OA治疗指南的修订中,有必要经常对一些新的循证依据进行系统性回顾。 | Zhang W Moskowitz RW Nuki G 曹月龙(节译) 高宁阳(节译) 庞坚(节译) 王翔(节译) 徐宇(节译) 段铁骊(节译) 赵咏芳(节译) 詹红生(节译) 石印玉(节译) | 2009 | 国际骨科学杂志2009，30，3： | 25 |

| 17 | Status monitoring and health assessment of Luhuitou fringing reef of Sanya, Hainan, China显示文摘The monitoring survey and health assessment for benthic community were carried out in Luhuitou fringing reef of Sanya, Hainan, China in 2002. Monitoring survey included manta tow, line intercept transect, video transect and digital photograph. The mean live coral cover was 23.40%. Comparison of used monitoring methods showed that video transect can replace line intercept transect, and 50 m transect is better than 20 m transect in uneven coral region. Survey data and comparison with previous research work showed that Luhuitou fringing reef has been damaged severely and has a general declining trend with live coral cover from about 85% in the 1960s down to 20% in 2004, but it still has quite high biodiversity and therefore has special protection value. Main factors of Luhuitou fringing reef declining were human activities including reef rock digging and curios collecting, destructive fishing, sediment and pollutant from coastal land, and recent marine aquaculture. Only strengthening integrated management can reach improvement and restoration of Luhuitou declining coral reef ecosystem. | ZHANG Qiaomin SHI Qi CHEN Gang FONG T C W WONG D C C HUANG Hui WANG Hankui ZHAO Meixia | 2006 | Chinese Science Bulletin2006，51，B12： | 15 |
