1Impacts of nighttime post-anthesis warming on rice productivity and grain quality in East China显示文摘The impacts of nighttime post-anthesis warming on rice productivity and grain quality in East China were evaluated for two cultivars, II You 128, an indica rice, and Wuyunjing 7, a japonica rice. Warming by 3.0 °C stimulated the nighttime respiration rate and decreased the photosynthesis rate, resulting in significant decreases of 21.2% and 24.9% in aboveground biomass accumulation for II You 128 and Wuyunjing 7, respectively. Warming significantly reduced the rates of seed setting and grain filling, especially of inferior kernels(those lower in panicles), while the filling rate of superior kernels remained almost unchanged. As a result, 1000-grain weight and grain yield were respectively 3.7% and 30.0% lower for II You 128 and 12.8% and 34.3% for Wuyunjing 7 in warmed plots than in the unwarmed control. Nighttime warming also significantly reduced the grain milling and appearance quality of both varieties. More negative effects of warming on inferior than on superior kernels were found. The above results have important implications for rice variety cultivation in East China.Wenjun Dong Jin Chen Lili Wang Yunlu Tian Bin Zhang Yongcai Lai Ying Meng Chunrong Qian Jia Guo 2014The Crop Journal2014,2,1:6
2China's Oil & Gas Imports and Exports in 2014显示文摘Domestic economic growth and oil demand growth lagged behind the expected in 2014, and net crude oil imports broke 300 million tons for the first time. Slower demand growth resulted in more severe surplus of refining capacity. Refined oil imports decreased by more than 10 million tons and net imports dropped to 700,000 tons in 2014. Liquefied petroleum gas(LPG) market boomed again and LPG imports created a new high of 7.1 million tons driven by chemical raw materials. The expanding momentum of imported natural gas market weakened obviously, but import dependence rose to 31%.Tian Chunrong 2015China Oil & Gas2015,22,1:2

4Long non-coding RNA HCAR promotes endochondral bone repair by upregulating VEGF and MMP13 in hypertrophic chondrocyte through sponging miR-15b-5p显示文摘Endochondral bone formation is an important route for bone repair.Although emerging evidence has revealed the functions of long non-coding RNAs(lncRNAs)in bone and cartilage development,the effect of lncRNAs in endochondral bone repair is still largely unknown.Here,we identified a lncRNA,named Hypertrophic Chondrocyte Angiogenesis-related lncRNA(HCAR),and proved it to promote the endochondral bone repair by upregulating the expression of matrix metallopeptidase 13(Mmp13)and vascular endothelial growth factorα(Vegfa)in hypertrophic chondrocytes.Lnc-HCAR knockdown in hypertrophic chondrocytes restrained the cartilage matrix remodeling and decrease the CD31hiEmcnhi vessels number in a bone repair model.Mechanistically,we proved that lnc-HCAR was mainly enriched in the cytoplasm using fluorescence in situ hybridization(FISH)assay,and it acted as a molecular sponge for miR-15b-5p.Further,in hypertrophic chondrocytes,lnc-HCAR competitively bound to miR-15b-5p to increase Vegfa and Mmp13 expression.Our results proved that lncRNA is deeply involved in endochondral bone repair,which will provide a new theoretical basis for future strategies for promoting fracture healing.Yun Bai Xiaoshan Gong Rui Dong Zhen Cao Ce Dou Chuan Liu Jianmei Li Fei Kang Jingjin Dai Chunrong Zhao Zhansone Tian Jiulin Tan Qijie Dai Shiwu Dong 2022Genes & Diseases2022,9,2:1
5A Supported Palladium on Gallium-based Liquid Metal Catalyst for Enhanced Oxygen Reduction Reaction显示文摘Developing high-performance catalysts for oxygen reduction reaction to replace costly platinum-based materials is of great importance but still confronted with challenges.Herein,a kind of supported palladium liquid metal catalyst,which is prepared by galvanic replacement,surpasses commercial Pt/C and Pd/C in oxygen reduction catalysis with a higher half-wave potential of 0.92 V,mass activity of 1.85 A/mgPd at 0.90 V,and superior durability.The liquid metal support can both optimize the electronic structures of Pd sites and guarantee the dispersion of Pd atoms,which explains the enhanced activity and durability,respectively.This work opens an avenue for rational design of catalysts.MA Chunrong SONG Bingyi MA Zhentao WANG Xiaoqian TIAN Lin ZHANG Haoran CHEN Cai ZHENG Xusheng YANG Li-ming WU Yuen 2022Chemical Research in Chinese Universities2022,38,5:0
6China's Oil and Gas Imports and Exports in 2012显示文摘In 2012, China’s net import of crude was 268.7 million tons, which is 18.63 million tons higher than that of the previous year. Net import of refined products increased greatly as the naphtha import climbed up and gasoline and diesel import shrank. Net LPG import had been reduced gradually for the third yearTian Chunrong 2013China Oil & Gas2013,20,1:0
7Analysis of China's Oil Imports and Exports in 2016显示文摘In 2016,China's net imports of crude oil increased to 378.3 million tons and its net exports of product oil soared to 20.45 million tons.Refinery crude runs continue to grow at a low rate,and the domestic product oil market still has a supply surplus.Diesel consumption fell for the first time in 21 years.The liquefied petroleum gas(LPG) market continues to grow rapidly,spurred on by feedstock demand for chemicals and gasoline blending components,and imports of LPG have reached a record high of 16.12 million tons.The refinery throughput of Petro China and SINOPEC had declined for 2 consecutive years,but crude oil imports climbed to a new high of 381 million tons as independent refineries boosted their utilization of capacity and the domestic oilfields produced a decreased amount of output.Imported oil now accounts for more than 2/3 of the Chinese market compared to being only about 1/3 15 years ago.Moreover,the proportion of imported crude in refinery runs has risen to 70%.In 2017,China's economy will continue to face substantial pressure,and domestic demand for product oil will continue to grow slowly.Tian Chunrong 2017China Oil & Gas2017,24,1:0
8Oil Import and Export in China显示文摘Domestic economic growth slowed down and supply exceeded demand in oil market in 2015, so the growth of refineries' processing volume was limited. Nevertheless, the gradual decontrol of market and the storage requirement under low oil price, crude oil imports hit a record high of 335.5 million tons, with the growth rate approximating 9%. Refined oil exports soared and imports decreased, which made China become a net refined oil exporter for the first time for 24 years, and net imports reached 6.22 million tons. Robust requirement on chemical raw materials propelled imported liquefied petroleum gas market to go on expanding. Imports exceeded 12 million tons in 2015, thus China leaped into the world's largest liquefied petroleum gas importer. In 2016, oil consumption growth would be kept at lower level. However, China would further decontrol crude oil import and refined oil export permits and put incremental storage capacity into use. Therefore, crude oil imports would continue to rise up, and refined oil exports may hit a new historic high. Imported liquefied petroleum gas market will enter into a stage of stable growth after two years' rapid development.Tian Chunrong 2016China Oil & Gas2016,23,1:0
9China's Oil & Gas Imports and Exports in 2011显示文摘Average oil price in international market exceeded 110 US dollars and hit historic high in 2011,but China's crude oil imports still rose to 273.78 million tons.Net imports of crude oil,refined oil,liquefied petroleum gas(LPG)and other oil products created another historic high.Oil dependency,i.e.the proportion of net oil imports to domestic consumption went on rising and rose to about 59.8% in 2011. Net imports of refined oil rose by 46% remarkably, indicating that the growth of processing capacity of domestic refineries lagged behind consumption of oil products.Tian Chunrong 2012China Oil & Gas2012,19,1:0
10Review of China's Petroleum Imports & Exports in 2005显示文摘在极大地增加三连续的年了以后,原油的网进口在中国在 2005 去了 5.2% 。在在有国际市场的中国市场的主要产品油的价格之间的价格倒置导致进口燃料和柴油和汽油和柴油机出口的增加的大减少。除了原油,包括产品油, LPG 和另外的油产品的油产品的网进口体积去年显然落下。Tian Chunrong 2006China Oil & Gas2006,13,1:0
11China's Oil Imports and Exports in 2007显示文摘The net imports of oil increased by 8.4% in China in 2007, hitting the record of 183.48 million tons (Fig.1). The net imports of crude oil and other oil products including paraffin wax, oil coke, and asphalt increased and balanced out the decrease of the net imports of product oil and liquefied petroleum gas (LPG). The net imports of crude oil reached 159.35 million tons, up 14.8%. In 2006, a lot of refining refineries were newly built and expanded,Tian Chunrong 2008China Oil & Gas2008,15,1:0
12China's Oil Imports and Exports in 2008显示文摘The net imports of oil,including crude oil,refined oil,LPG and other oil products,increased by 9.5% in 2008 and rose to 200.67 million tons from 183.28 milliontons in 2007(Fig.1,Fig.2).The net imports of crude oil reached 175.16 million tons,up by 9.9%.Tian Chunrong 2009China Oil & Gas2009,16,1:0
13China’s Petroleum Imports and Exports in 2010显示文摘Net imports of crude oil, product oil, liquefied petroleum gas (LPG), and other oil products rose by 16.2% and hit a historic high of 253.7 million tons in 2010.Among these, net imports of crude oil reached 236.3 million tons, 93% of the total, and the growth rate was as high as 19.0% (see Fig.1).As the demand for oil products maintained a robust growth and the scale of oil refineries was expanded further, China's processing quantity of crude oil rose by 50 million tons in 2010, 13.4% higher than the figure in 2009.Sales of oil products were brisk, in particular diesel demand was increased suddenly in the fourth quarter of 2009.Therefore, China's apparent need (production + net imports) of seven kinds of main oil products including gasoline, kerosene, diesel, lubricant oil, fuel oil, LPG and chemical light oil was increased by 11.6% in 2010 (Table 1 and Table 2).Tian Chunrong 2011China Oil & Gas2011,18,1:0
14Panorama of China's Petroleum Imports and Exports in 2006显示文摘更加,在 Chinasince,很快发达的经济为燃料有一个迫切要求的石油进口增加的 2006 锯的一年。中国“自从 2003, s 经济以超过 10% 的高率发展中四连续的年了。在在 2006 的中国的在10.7%的粗野国内产品( GDP )玫瑰,自从 1999 .China ,它是最高的速度“对油产品的 s 需求比在 2005 在 2006 更快增加了,它对主要的油产品的明显的要求更高是6%,它几乎等于精制植物的国内油的处理能力的增长。中国“原油的 s 进口由于处理并且精制能力增加一直在升起五连续的年了。Tian Chunrong 2007China Oil & Gas2007,14,1:0
15China's Oil Imports and Exports in 2009显示文摘The so-called imported oil dependence degree commonly refers to the proportion of oil imported to China’s oil consumption, which hit 56% in 2009 and has exceeded 50% in 2007. In the past two years,Tian Chunrong 2010China Oil & Gas2010,17,1:0
16China's Oil & Gas Imports and Exports in 2013显示文摘Demand for imported oil is weakened by economic growth decline.In 2013,growth of China’s oil imports dropped to the lowest in 8 years,but net imports topped 300 million tons.Domestic oil demand will continue to grow slightly in 2014,and development of alternative fuels will restrict growth of oil import.Tian Chunrong 2014China Oil & Gas2014,21,1:0
17Analysis of China's Oil Imports and Exports Situation显示文摘China's oil import dependence had risen to 72% in 2017, while its net imports of various oil products,including crude oil, refined oil, liquefied petroleum gas(LPG) and other products, had climbed to 418.8 million tons, an increase by10.7% over 2016. China's crude oil import reached 420 million tons, surpassed the United States for the first time, and China had become the biggest crude oil importing country in the world. Net export of the refined oil, mainly the diesel, continued to increase to 22.7 million tons, as driven by the oversupply situation of the domestic market. Last year, China's LPG import was 18.45 million tons, but its growth was diminishing.Oil price would continue to rise in 2018, while the domestic demand of refined oil would be maintained at a lower rate of growth. However, driving by new refining capacities to be brought online, it is estimated that the crude oil import would still be increased remarkably. LPG import would reach a new high due to the growth potential and strong demand for feedstocks in the petrochemical product market.Tian Chunrong 2018China Oil & Gas2018,25,3:0
