目的探讨空腹血糖受损(IFG)冠心病患者冠状动脉病变特点,与血高敏C反应蛋白(hs-CRP)水平的关系及意义。方法对经冠脉造影确诊的冠心病患者行口服葡萄糖耐量试验(OGTT),据结果用1999年WHO标准选取冠心病合并IFG组69例,另设糖代谢正常冠心病组64例(对照组)。测定两组体重、血压、血脂、血肌酐、血hs-CRP,记录其年龄、冠心病危险因素(性别、高血压、高胆固醇血症、吸烟)和冠状动脉造影结果并计算冠脉病变积分。结果血hs-CRP水平、冠脉病变积分在IFG组较对照组明显升高(P<0.01);相关分析显示,在冠心病合并IFG患者中,空腹血糖水平、血hs-CRP水平与冠脉病变Gensini评分呈正相关(r分别=0.2685,0.5232均P<0.05)。结论冠心病合并IFG患者冠脉病变严重,多支冠脉病变发生率高,病变呈弥漫性狭窄。冠心病合并IFG患者存在炎症反应,血hs-CRP水平与冠脉狭窄程度相关。

Tide- and wind-driven variability of water level in Sansha Bay, Fujian, China

This study analyzes water-level variability in Sansha Bay and its adjacent waters near Fujian, China, using water-level data observed from seven stations along the coast and wind data observed from a moored buoy near Mazu Island. At super-to near-inertial frequencies, tides dominated the water-level variations, mainly characterized by semi-diurnal （prmafily M2, S2, and N2） and diurnal tides （primarily Kb O1）. The correlation coefficients between residual （non-tidal） water-level time series and the observed wind-stress time series exceeded 0.78 at all stations, hinting that the wind acting on the study region was another factor modulating the water-level variability. A cross-wavelet and wavelet-coherence analysis further indicated that （i） the residual water level at each station was more coherent and out-of-phase with the alongshore winds mostly at sub-inertial time scales associated with synoptic weather changes; and （ii） the residual water-level difference between the outer and inner bay was more coherent with the cross-shore winds at discrete narrow frequency bands, with the wind leading by a certain phase. The analysis also implied that the monsoon relaxation period was more favorable for the formation of the land-sea breeze, modulating the residual water-level difference.

Molecular structure of kerogens from source rocks of the Tarim Basin: A study by Py-GC-MS and methylation-Py-GC-MS

引用

Science China Earth Sciences 2005年第3期48卷 313-325页

作者： jia Wanglu peng Ping'an State Key Laboratory of Organic Geochemistry Guangzhou Institute of Geochemistry Chinese Academy of Sciences Guangzhou 510640 China State Key Laboratory of Organic Geochemistry Guangzhou Institute of Geochemistry Chinese Academy of Sciences Guangzhou 510640 China

Flash pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS) and in situ methylation-pyrolysis-gas chromatography-mass spectrometry (methylation-Py-GC-MS) have been employed for a study of molecular structure of kerogens from source rocks of the Tarim Basin. The main products from Py-GC-MS of the Ordovician and Triassic kerogens from the Tarim Basin are n-alkanes and n-alk-1-enes which decrease in relative abundance with in- creased carbon number. The major products from methylation-Py-GC-MS are normal saturated fatty acid methyl esters which show maxima at C16 and C18. These aliphatic compounds are mainly from lipids of planktonic algae. Moreover, there are more abundant long-chain fatty acids (C20-C26) and normal n-alkanes and n-alk-1-enes (C15-C25) in pyrolysates of Triassic kerogens than that of Ordovician kerogens, reflecting the discrepancies in sources of the Triassic kerogens and the Ordovician kerogens. Besides these aliphatic compounds, methoxyl benzoic acid methyl esters were detected only in products from methylation-Py-GC-MS of late Ordovician kerogen TAC1-1, which possibly was the first molecular evidence for the appearance of moss or other terrestrial plants in the Tarim Basin. In addition, the relative intensity of 17β(H)-trisnorhopane, 17 β(H),21 α(H)-30-normoretane and 17 β(H)-moretane is lower, but 17α(H)-trisnorhopane and 17 α(H)-30-norhopane is higher in the pyrolysates of the Ordovician kerogens in comparison with the pyrolysates of the Triassic kerogens. Moreover, Pr-1-ene has been detected in pyrolysates of Triassic kerogens. These differences in pyrolysates consist with maturity of kerogens. In conclu- sion, combination of methylation-Py-GC-MS and Py-GC-MS are useful tools to investigate the molecular structure of geomacromolecules and can be subject to type the organic matter, com- pare the maturity of kerogens and carry out the oil-source correlation.

Simulation of a ground-layer adaptive optics system for the Kunlun Dark Universe Survey Telescope

引用

Research in Astronomy and Astrophysics 2013年第7期13卷 875-884页

作者： peng jia Sijiong Zhang School of Astronomy and Space Science Nanjing University National Astronomical Observatories/Nanjing Institute of Astronomical Optics&Technology Chinese Academy of Sciences Key Laboratory of Astronomical Optics&Technology Nanjing Institute of Astronomical Optics & Technology Chinese Academy of Sciences Key Laboratory of Modern Astronomy and Astrophysics Ministry of Education

Ground Layer Adaptive Optics （GLAO） is a recently developed technique extensively applied to ground-based telescopes, which mainly compensates for the wavefront errors induced by ground-layer turbulence to get an appropriate point spread function in a wide field of view. The compensation results mainly depend on the turbu-lence distribution. The atmospheric turbulence at Dome A in the Antarctic is mainly distributed below 15 meters, which is an ideal site for applications of GLAO. The GLAO system has been simulated for the Kunlun Dark Universe Survey Telescope, which will be set up at Dome A, and uses a rotating mirror to generate several laser guide stars and a wavefront sensor with a wide field of view to sequentially measure the wavefronts from different laser guide stars. The system is simulated on a computer and parameters of the system are given, which provide detailed information about the design of a practical GLAO system.
