作者： Cheng-Long GUO Xian-Peng YU bang-Guo YANG Meng-Meng LI Ji-Qiang he Quan LI Cheng-Xiong GU Shu-Zheng LYU jian-Zeng DONG Department of Cardiology Beijing Anzhen Hospital Capital Medical University Beijing China Department of Cardiac Surgery Beijing Anzhen Hospital Capital Medical University Beijing China

Background There are limited data on long-term （〉 5 years） outcomes of drug-eluting stent （DES） implantation compared with coro- nary artery bypass grafting （CABG） for ostial/rnidshaft left main coronary artery （LMCA） lesions. Methods Of the 259 consecutive pa- tients in Beijing Anzhen Hospital with ostial/midshaff LMCA lesions, 149 were treated with percutaneous coronary intervention （PCI） with DES and 110 were with CABG. The endpoints of the study were death, repeat revascularization, myocardial infarction （MI）, stroke, the composite of cardiac death, and major adverse cardiac and cerebrovascular events （MACCE, the composite of cardiac death, MI, stroke or repeat revascularization）.The duration of follow-up is 7.1 years （interquartile range 5.3 to 8.2 years）. Results There is no significant differ- ence between the PCI and CABG group during the median follow-up of 7.1 years （interquartile range： 5.3-8.2 years） in the occurrence of death （HR： 0.727, 95% CI： 0.335-1.578; P = 0.421）, the composite endpoint of cardiac death, MI or stroke （HR： 0.730, 95% CI： 0.375-1.421; P = 0.354）, MACCE （HR： 1.066, 95% CI： 0.648-1.753; P = 0.801）, MI （HR： 1.112, 95% CI： 0.414-2.987; P = 0.833）, stroke （HR： 1.875, 95% CI： 0.528-6.659; P = 0.331）, and repeat revascularization （HR： 1.590, 95% CI： 0.800-3.161; P = 0.186）. These results remained after multivariable adjusting. Conclusion During a follow-up up to 8.2 years, we found that DES implantation had similar endpoint outcomes compared with CABG.

作者： Han-Pei Zhao Mei-Yi Yao Jiao Huang Jin-Long Zhang jian-Chao Peng bang-Xin Zhou Laboratory for Microstructure Shanghai UniversityShanghai200444China Institute of Materials Shanghai UniversityShanghai200072China

The effect of Bi addition(0.05 wt%-0.50 wt%)on the microstructure of zirconium alloys,including T5(Zr-0.7 S n-1.0 Nb-0.3 Fe-0.1 Cr),S5(Zr-0.8 Sn-0.35 Nb-0.4 Fe-0.1 Cr),Zr-4(Zr-1.5 Sn-0.2 Fe-0.1 Cr) and Zr-1 Nb,was investigated by transmission electron microscopy(TEM),energy-dispersive spectroscopy(EDS) and selected area electron diffraction(SAED).Results show that with the increase in Bi content,h-Zr(Fe,Cr,Nb)2,o-Zr(Fe,Sn,Bi)_(2) and Zr-Fe-Cr-Nb-Sn-Bi second-phase particles(SPPs) precipitate successively in the T5+xBi and S5+xBi alloys;in the Zr-4+xBi alloys,h-Zr(Fe,Cr)2,o-Zr(Fe,Sn,Bi)2,Zr-Fe-Cr-Sn-Bi and Zr-Fe-Cr-Bi SPPs are detected *** as for Zr-1 Nb+xBi alloys,Bi-free SPPs *** addition of Bi promotes the precipitation of SPPs with Sn in the *** concentration of Bi dissolved in α-Zr matrix increases with the decrease in Sn content in the *** reasonable Bi has little influence on the solid solution content of Nb in α-Zr matrix.

Assessment of Soil Organic Carbon Stock in the Upper Yangtze River Basin

Journal of Mountain Science 2013年第5期10卷 866-872页

作者： WANG Xiao-guo ZHU Bo HUA Ke-ke LUO Yong ZHANG jian ZHANG An-bang Key Laboratory of Mountain Surface Processes and Ecological Regulation Chinese Academy of Sciences henan Institute of Science and Technology

Soil organic carbon is of great importance to terrestrial ecosystems. Studies on the amount and spatial distribution of soil organic carbon stock in various types of soil can help to better understand the role of soil in the global carbon cycle and provide a scientific basis for the assessment of the magnitude of carbon stored in a given area. here we present estimates of soil organic carbon stock in soils in the upper reaches of the Yangtze River based on soil types as defined by Chinese Soil Taxonomy and recently compiled into a digital soil database. The results showed that the total soil organic carbon stock of the upper Yangtze River to a depth of 100 cm was 1.452x1013 kg. The highest soil organic carbon stock was found in felty soils （2.419x10TM kg）, followed by dark brown soils （1.269x10=kg）, and dark feltysoils （L139x10=kg）. Chernozems and irrigation silting soils showed the lowest soil organic carbon stock, mainly due to the small total area of such soils. The soil organic carbon density of these major soil types ranged from 5.6 to 26.1 kg m2- The average soil organic carbon density of the upper reaches of the Yangtze River was 16.4 kg m-2, which was higher than that of the national average. Soil organic carbon density indicated a distinct decreasing trend from west to east, which corresponds to the pattern of increasing temperature from cold to subtropical.

【目的】研究外源脱落酸(ABA)对干旱胁迫下狗牙根(Cynodon dactylon)光合特性的影响,为缓解狗牙根干旱损伤及抗旱栽培提供参考依据。【方法】利用聚乙二醇(Polyethylene glycol-6000,PEG-6000)模拟中度和重度干旱胁迫,研究干旱胁迫和外源ABA(200,500μmol/L)对狗牙根幼苗光合色素、净光合速率、气孔导度和叶绿素荧光参数等光合指标的影响。【结果】干旱胁迫降低了狗牙根叶绿素含量、净光合速率、最大荧光(Fm)、可变荧光(Fv)、电子传递速率(ETR),提高了光化学猝灭(qP)和非光化学猝灭(NPQ)(P<0.05)。外源ABA降低了干旱胁迫对光合的抑制作用,不过其效应与喷施浓度及干旱程度有关。中度干旱胁迫下,喷施500µmol/L ABA使叶绿素含量、PSII最大光化学量子产量(Fv/Fm)、qP显著提高(P<0.05);重度干旱胁迫下,外源500µmol/L ABA提高了狗牙根叶绿素含量、净光合速率和水分利用率,降低了胞间CO_(2)浓度(P<0.05),但对叶绿素荧光参数影响不显著。【结论】外源ABA可通过提高光合色素含量、水分利用率及光能转化效率等形式缓解干旱胁迫对狗牙根幼苗的伤害,使植株更好地适应干旱环境,其中喷施浓度为500µmol/L效果较好。

Effects of Nutrient Limitation on Pigments in Thalassiosira weissflogii and Prorocentrum donghaiense

引用

Journal of Integrative Plant Biology 2007年第5期49卷 686-697页

作者： jian-Jun Hou bang-Qin Huang Zhen-Rui Cao Ji-Xin Chen Hua-Sheng Hong State Key Laboratory of Marine Environmental Science Xiamen University Xiamen 361005 China College of Fisheries Huazhong Agricultural University Wuhan 430070 China Hubei Institute for Nationalities Enshi 445000 China

The response of Prorocentrum donghaiense and Thalassiosira weissfiogii pigments under nitrate （N） and phosphate （P） limitation were studied using HPLC and in vivo fluorescence protocols in batch cultures. For P. donghaiense, the pigment ratio was kept stable under different nutrient conditions from the results of HPLC. For T. weissflogii, there was a lower ratio of chlorophyllide to Chl a during the exponential phase, but the reverse during the stationary phase. Different members of the phytoplankton had different pigments response mechanisms under nutrient limitation. From the results of in vivo fluorescence, the ratio of peridinin to Chl a for P. donghaiense increased in nutrient-free culture, while it was kept stable for nutrient-limited cultures during the exponential phase. For T. weissflogii, the ratio of fucoxanthin to Chl a for each culture increased during the exponential phase, but the ratio under N limitation was apparently lower than that for P limitation during the stationary phase. The results indicate that both pigment ratios from HPLC and in vivo fluorescence of To weissflogii were changed greatly under different nutrient conditions, which suggests that both ratios could be used as indicators of algal physiological status in different nutrient conditions.

Drought over China in the 21st Century: Results of RegCM3

引用

Atmospheric and Oceanic Science Letters 2012年第6期5卷 509-513页

作者： LIU Ke jianG Da-bang MA jian-Yong Nansen-Zhu International Research Centre Institute of Atmospheric Physics Chinese Academy of Sciences Beijing 100029 China Climate Change Research Center Chinese Academy of Sciences Beijing 100029 China University of Chinese Academy of Sciences Beijing 100049 China Key Laboratory of Regional Climate-Environment Research for Temperate East Asia Chinese Academy of Sciences Beijing 100029 China Institute of Environment and Sustainable Development in Agriculture Chinese Academy of Agricultural Sciences Beijing 100081 China

Based on 150-year simulations of a regional climate model, RegCM3, under the Special Report on Emissions Scenarios (SRES) A1B scenario, the effective drought index (EDI) is used to project the future drought change in China. During the baseline period 1986-2005, RegCM3 was found to reliably simulate the spatial pattern of drought over the country. Over the 21st century, the regionally averaged EDI should increase, corresponding to a decrease of drought, while the probability of extreme drought events should increase. Geographically, drought should clearly increase in Northeast China, the middle and lower reaches of the Yangtze River valley, Southwest China, and southern Tibet but decrease in most parts of the rest of the country.
