| 1 | Contrasting trends of PM2.5 and surface-ozone concentrations in China from 2013 to 2017显示文摘Although much attention has been paid to investigating and controlling air pollution in China,the trends of air-pollutant concentrations on a national scale have remained unclear.Here,we quantitatively investigated the variation of air pollutants in China using long-term comprehensive data sets from 2013 to 2017,during which Chinese government made major efforts to reduce anthropogenic emission in polluted regions.Our results show a significant decreasing trend in the PM2.5 concentration in heavily polluted regions of eastern China,with an annual decrease of〜7%compared with measurements in 2013.The measured decreased concentrations of SO2>NO2 and CO(a proxy for anthropogenic volatile organic compounds)could explain a large fraction of the decreased PM2.5 concentrations in different regions.As a consequence;the heavily polluted days decreased significantly in corresponding regions.Concentrations of organic aerosol;nitrate;sulfate,ammonium and chloride measured in urban Beijing revealed a remarkable reduction from 2013 to 2017;connecting the decreases in aerosol precursors with corresponding chemical components closely.However;surface-ozone concentrations showed increasing trends in most urban stations from 2013 to 2017;which indicates stronger photochemical pollution.The boundary-layer height in capital c让ies of eastern China showed no significant trends over the Beijing-Tianjin-Hebei,Yangtze River Delta and Pearl River Delta regions from 2013 to 2017;which confirmed the reduction in anthropogenic emissions.Our results demonstrated that the Chinese government was successful in the reduction of particulate matter in urban areas from 2013 to 2017,although the ozone concentration has increased significantly;suggesting a more complex mechanism of improving Chinese air quality in the future. | Yonghong Wang Wenkang Gao Shuai Wang Tao Song Zhengyu Gong Dongsheng Ji Lili Wang Zirui Liu Guiqian Tang Yanfeng Huo Shili Tian Jiayun Li Mingge Li Yuan Yang Biwu Chu Tuukka Petaja Veli-Matti Kerminen Hong He Jiming Hao Markku Kulmala Yuesi Wang Yuanhang Zhang | 2020 | National Science Review2020，7，8： | 51 |
| 2 | The Reference Genome of Tea Plant and Resequencing of 81 Diverse Accessions Provide Insights into Its Genome Evolution and Adaptation显示文摘Tea plant is an important economic crop,which is used to produce the world's oldest and most widely consumed tea beverages.Here,we present a high-quality reference genome assembly of the tea plant(Camellia sinensis var.sinensis)consisting of 15 pseudo-chromosomes.LTR retrotransposons(LTR-RTs)account for 70.38%of the genome,and we present evidence that LTR-RTS play critical roles in genome size expansion and the transcriptional diversification of tea plant genes through preferential insertion in promoter regions and introns.Genes,particularly those coding for terpene biosynthesis pro-teins,associated with tea aroma and stress resistance were significantly amplified through recent tandem duplications and exist as gene clusters in tea plant genome.Phylogenetic analysis of the sequences of 81 tea plant accessions with diverse origins revealed three well-differentiated tea plant populations,support-ing the proposition for the southwest origin of the Chinese cultivated tea plant and its later spread to western Asia through introduction.Domestication and modern breeding left significant signatures on hundreds of genes in the tea plant genome,particularly those associated with tea quality and stress resis-tance.The genomic sequences of the reported reference and resequenced tea plant accessions provide valuable resources for future functional genomics study and molecular breeding of improved cul-tivars of tea plants. | Enhua Xia Wei Tong Yan Hou Yanlin An Linbo Chen Qiong Wu Yunlong Liu Jie Yu Fangdong Li Ruopei Li Penghui Li Huijuan Zhao Ruoheng Ge Jin Huang Ali Inayat Mallano Yanrui Zhang Shengrui Liu Weiwei Deng Chuankui Song Zhaoliang Zhang Jian Zhao Shu Wei Zhengzhu Zhang Tao Xia Chaoling Wei Xiaochun Wan | 2020 | Molecular Plant2020，13，7： | 51 |

| 5 | Variability and reduction of atmospheric pollutants in Beijing and its surrounding area during the Beijing 2008 Olympic Games显示文摘The Beijing-Tianjin-Hebei Atmospheric Environment Monitoring Network was established by the Institute of Atmospheric Physics,Chinese Academy of Sciences.The goals of the network were to monitor and provide warnings of the atmospheric quality in Beijing and its surrounding area during the Beijing 2008 Olympic Games.The results showed that the atmospheric complex pollution exhibited high concentrations of ozone and fine particles and oxidation in summer,with a ubiquitous regional source.The regional mean concentrations of SO2,PM2.5,NO2,and O3_8h max(the maximum daily 8 h mean) and Ox were 22±11,90±40,25±5,136±35 and 112±21 μg/m3 in summer,respectively.During the Olympic Games,the mean concentration of SO2,PM2.5,NO2,O3_8h max,and Ox were 12.5±4,56±28,23±4,114±29,95±17 μg/m3 in the region,respectively,and fell by 51.0%,43.7%,13%,20.2%,and 18.9%,respectively,compared to the prophase mean before the Olympic Games.The concentration of atmospheric pollutants declined significantly and achieved the 'Green Olympics' control goal of air quality.After the Olympic Games,SO2,PM2.5 and NOx increased significantly as the temporary atmospheric pollution control measures were terminated. | XIN JinYuan WANG YueSi TANG GuiQian WANG LiLi SUN Yang WANG YingHong HU Bo SONG Tao JI DongSheng WANG WeiFeng LI Liang LIU GuangRen | 2010 | Chinese Science Bulletin2010，55，18： | 30 |
| 6 | Coalbed methane genesis, occurrence and accumulation in China显示文摘Coalbed methane (CBM) is an important type of unconventional gas. Commercial development of CBM in America has been very successful since the 1980s. The CBM industry in Australia and Canada has developed rapidly during the last decade. Commercial development of CBM in China started in the 1990s, and has made great progress. The geological theory of CBM in China has achieved great advancement in genesis, occurrence and accumulation. On the aspect of CBM genesis, five CBM genetic types (primary biogenic gas, secondary biogenic gas, thermal degradation gas, pyrolysis gas and mixed gas) are identified by studying the geochemical characteristics of CBM, and a tracing indicator system is established. The discovery of secondary biogenic gas in medium-high rank coal reservoirs has widened the potential of CBM resources. On the aspect of CBM occurrence, the gas adsorption regulation under combined action of temperature and pressure is revealed by conducting adsorption experiments of different coal ranks under varying temperature and pressure conditions. Besides, by applying the adsorption potential theory in CBM research, the adsorption model under combined action of temperature and pressure is established. The new model can predict CBM resources accurately, and overcome the limitation of the traditional Langmuir model which uses just a single factor to describe the adsorption characteristics of deep buried coal. On the aspect of CBM accumulation, it is proposed that there are three evolutionary stages during CBM accumulation, including gas generation and adsorption, unsaturated gas adsorption, gas desorption-diffusion and preservation. Controlled by tectonic evolution, hydrodynamics and sealing conditions, CBM tends to be regionally enriched in synclines. Advances in geological theory of CBM in China can not only improve understanding of natural gas, but also provide new ideas for further exploration of CBM. | Song Yan Liu Shaobo Zhang Qun Tao Mingxin Zhao Mengjun Hong Feng | 2012 | Petroleum Science2012，9，3： | 29 |
| 7 | Temperature effect and thermal impact in lithium-ion batteries: A review显示文摘Lithium-ion batteries, with high energy density(up to 705 Wh/L) and power density(up to 10,000 W/L), exhibit high capacity and great working performance. As rechargeable batteries, lithium-ion batteries serve as power sources in various application systems. Temperature, as a critical factor, significantly impacts on the performance of lithium-ion batteries and also limits the application of lithium-ion batteries. Moreover, different temperature conditions result in different adverse effects. Accurate measurement of temperature inside lithiumion batteries and understanding the temperature effects are important for the proper battery management. In this review, we discuss the effects of temperature to lithium-ion batteries at both low and high temperature ranges.The current approaches in monitoring the internal temperature of lithium-ion batteries via both contact and contactless processes are also discussed in the review. | Shuai Ma Modi Jiang Peng Tao Chengyi Song Jianbo Wu Jun Wang Tao Deng Wen Shang | 2018 | Progress in Natural Science:Materials International2018，28，6： | 27 |

| 10 | Trends in particulate matter and its chemical compositions in China from 2013–2017显示文摘Accurate determination of the atmospheric particulate matter mass concentration and chemical composition is helpful in exploring the causes and sources of atmospheric enthalpy pollution and in evaluating the rationality of environmental air quality control strategies.Based on the sampling and chemical composition data of PM2.5 in different key regions of China in the CARE-China observation network,this research analyzes the environmental air quality data released by the China National Environmental Monitoring Centre during the studied period to determine the changes in the particulate matter mass concentration in key regions and the evolution of the corresponding chemical compositions during the implementation of the Action Plan for Prevention and Control of Air Pollution from 2013-2017.The results show the following.(1)The particulate matter mass concentration in China showed a significant downward trend;however,the PM2.5 annual mass concentration in 64%of cities exceeds the New Chinese Ambient Air Quality Standard(CAAQS)GradeⅡ(GB3095-2012).The region to the east of the Taihang Mountains,the Fenhe and Weihe River Plain and the Urumqi-Changji regions in Xinjiang,all have PM2.5 concentration loading that is still high,and heavy haze pollution occurred frequently in the autumn and winter.(2)During the heavy pollution in the autumn and winter,the concentrations of sulfate and organic components decreased significantly.The mean SO42-concentration in PM2.5 decreased by 76%,12%,81%and 38%in Beijing-Tianjin-Hebei(BTH),the Pearl River Delta(PRD),the Sichuan-Chongqing region(SC)and the Fenhe and Weihe River Plain,respectively.The mean organic matter(OM)concentration decreased by 70%,44%,48%and 31%,respectively,and the mean concentration of NH4+decreased by 68%,1.6%,38%and 25%,respectively.The mean elemental carbon(EC)concentration decreased by 84%and 20%in BTH and SC,respectively,and it increased by 61%and 11%in the PRD and Fenhe and Weihe River Plain,respectively.The mean concentration of mineral and unresolved chemical components(MI)dropped by 70%,24%and 13%in BTH,the PRD and the Fenhe and Weihe River Plain,respectively.The change in the PM2.5 chemical composition is consistent with the decrease of the PM2.5mass concentration.(3)In 2015,the mean OM concentration contributions to fine particles and coarse particles were 13-46%and 46-57%,respectively,and the mean MI concentration contributions to fine particles and coarse and particles were 31-60%and 39-73%,respectively;these values are lower than the 2013 values from the key regions,which is the most important factor behind the decrease of the particulate matter mass concentration.From 2013 to 2015,among the chemical components of different particle size fractions,the peak value of the coarse particle size fraction decreased significantly,and the fine particle size fractions of SO42-,NO3-,and NH4+decreased with the decrease of the particulate matter mass concentration in different particle size fractions.The fine-particle size peaks of SO42-,NO3-and NH4+shifted from 0.65-1.1μm to the finer size range of0.43-0.65μm during the same time frame. | Yuesi WANG Wenjie LI Wenkang GAO Zirui LIU Shili TIAN Rongrong SHEN Dongsheng JI Shuai WANG Lili WANG Guiqian TANG Tao SONG Mengtian CHENG Gehui WANG Zhengyu GONG Jiming HAO Yuanhang ZHANG | 2019 | Science China Earth Sciences2019，62，12： | 23 |
| 11 | Development of mechatronic driving system for seed meters equipped on conventional precision corn planter显示文摘Precision planters are more and more widely used for planting corn in China.Seed meters of conventional precision corn planters are usually driven by ground wheel and chain and sprocket system at present.Because of the slippage of ground wheels and vibration of chains,planting accuracy cannot be ensured,especially at higher forward speed.To improve the planting performance of precision planters,a mechatronic driving system was designed and its field working performance was evaluated in this research.A two-row pneumatic precision planter was modified to allow simultaneously using two different driving systems,i.e,with one row unit equipped with the newly designed mechatronic driving system and the other row unit equipped with conventional mechanical driving system,and used for planting at three forward speeds(9,11 and 12 km/h)on no-tillage and rotary-tillage lands.The distances between adjacent seeds in each plot were measured and the indices of uniformity in seed spacing,quality of feeding index(QFI),missing-seeding index and precision index were analyzed.With the average 4.70%increase of QFI and 3.54%decrease of missing-seeding index,the mechatronic driving system performed better than the mechanical driving system both on no-tillage and rotary-tillage lands at each forward speed.The values of QFI,missing-seeding index and precision index of the mechatronic driving system on rotary-tillage land are comparable to those on no-tillage land,by contrast,these indices of the mechanical driving system on rotary-tillage land are significantly worse than those on no-tillage land.The result indicates that the mechatronic driving system can eliminate the effect of ground wheel slippage on planting quality and maintain the uniformity of seed distribution.Although the QFI,missing-seeding index and precision index become worse with the increase of forward speed,with the worst values of QFI of 89.93%,missing-seeding index of 5.08%and precision index of 18.92%at the highest forward speed of 12 km/h,the mechatronic driving system can reduce the effect of forward speed on planting accuracy effectively.The result indicates that planters equipped with the mechatronic driving system are suitable for high speed planting.As compared to the mechanical driving system,the advantage of the mechatronic driving system is more noticeable especially when the forward speed is more than 11 km/h. | Yang Li He Xiantao Cui Tao Zhang Dongxing Shi Song Zhang Rui Wang Mantao | 2015 | International Journal of Agricultural and Biological Engineering2015，8，4： | 22 |

| 13 | XingNaoJing injections protect against cerebral ischemia/reperfusion injury and alleviate blood-brain barrier disruption in rats, through an underlying mechanism of NLRP3 inflammasomes suppression显示文摘The aim of this study was to explore the neuroprotective effect and mechanism of XingNaoJing injections(XNJ) on cerebral ischemia injury and blood-brain barrier(BBB) disruption. Middle cerebral artery occlusion(MCAO) method was applicated to establish the model of cerebral ischemia/reperfusion(I/R) injury in rats. BBB permeability after I/R injury was assessed with the leaking amount of Evans Blue and the expression of occludin and ZO-1. The expression of NOD-like receptor family, pyrin domain containing(NLRP3) was checked to explore the inhibition of inflammation by XNJ. The results showed that XNJ could significantly increase the survival percent, decrease the infarct area and ameliorate neurological deficits and brain damage after I/R injury. Leaking amount of Evans Blue was reduced by XNJ, and the expression of tight junction protein, occludin and ZO-1 was also up-regulated by XNJ, which showed a role of protection on BBB disruption. The expression of NLRP3 was inhibited after exposure of XNJ, which was associated with inhibition of the inflammatory response. In summary, XNJ could suppress NLRP3 inflammasomes and improve BBB disruption and brain damage in rats after cerebral I/R injury, which provided a beneficial insight to further explore XNJ. | QU Xiao-Yu ZHANG Yue-Ming TAO Li-Na GAO Huan ZHAI Jing-Hui SUN Jing-Meng SONG Yan-Qing ZHANG Si-Xi | 2019 | Chinese Journal of Natural Medicines2019，17，7： | 20 |

| 15 | Changes of meibomian glands in patients with type 2diabetes mellitus显示文摘AIM: To investigate the morphological changes of meibomian glands in patients with type 2 diabetes mellitus(DM).·METHODS: Of 118 eyes(118 patients) with type 2 DM(DM group) and 100 eyes of 100 control subjects(control group) were enrolled. After completing an ocular surface disease index(OSDI) questionnaire, the non-invasive tear film break-up time(NI-BUT) and the structure of the meibomian glands(MGs, meibography) were assessed by the Keratograph 5M system. Partial or complete loss of MG was scored for each eyelid from grade 0(no loss) to grade 3(lost area was >2/3 of the total MG area), which were also examined by laser scanning confocal microscopy(LSCM). The primary outcomes were meibomian gland acinar unit density(MGAUD),meibomian gland acinar longest diameter(MGALD) and meibomian gland acinar shortest diameter(MGASD).·RESULTS: Compared with control group, the OSDI was significantly higher in DM group(Z =-5.916; P <0.001),while the NI-BUT was significantly lower(Z =-7.765; P <0.001). Keratograph showed that there were more MGs dropout in DM group than that in control group. The meiboscore was significantly higher in DM group compared with control group(Z =-3.937; P <0.001).LSCM revealed that there were cytological alterations of MGs in DM group compared with control group, which included enlargement of MG acinar units and decreased in density of MG acinar units. Specifically, there were lower MGAUD, larger MGALD and MGASD in DM group than control group(Z =-10.120,-9.4442,-7.771; P <0.001).· CONCLUSION: Compared with the normal control participants, the patients with type 2 DM had more unstable tear films and severe symptoms of dry eye.Using Keratograph 5M system and LSCM, we found that the patients with type 2 DM had more significant morphological and cytological changes and dysfunction in MGs. | Tao Yu Wei-Yun Shi Ai-Ping Song Yang Gao Guang-FuDang Gang Ding | 2016 | International Journal of Ophthalmology(English edition)2016，9，12： | 19 |
| 16 | Biocompatibility of bio-Mg-Zn alloy within bone with heart, liver, kidney and spleen显示文摘A magnesium-zinc alloy rod was implanted into the marrow cavity of the distal femur in New Zealand rabbits. The femur with the implanted alloy was compared with the contralateral femur in which a bone tunnel without implant was formed as a control. Degradation of the magnesium-zinc alloy was analyzed via X-ray, scanning electron microscopy, and element energy spectrum analysis. Serum magnesium, liver and kidney function tests, and myocardial enzymes were measured. Heart, liver, kidney and spleen were sectioned for pathological analysis, and the effects of the implanted material on the histology and function of important organs were analyzed. Magnesium-zinc alloy was resorbed from the bone marrow cavity of the femur; 87% of the alloy was degraded within 14 weeks after the surgery. There were no significant differences in serum magnesium, liver or kidney function tests, or myocardial enzymes be- fore the surgery and after degradation of the magnesium-zinc alloy. Histology of the heart, liver, kidney, and spleen did not change. This study demonstrated that magnesium-zinc alloy can be resorbed in bone, and that the degradation products have good biocompatibility with heart, liver, kidney, and spleen. | HE YaoHua TAO HaiRong ZHANG Yan JIANG Yao ZHANG ShaoXiang ZHAO ChangLi LI JiaNan ZHANG BeiLei SONG Yang ZHANG XiaoNong | 2009 | Chinese Science Bulletin2009，54，3： | 18 |
| 17 | Molecular hydrogen:current knowledge on mechanism in alleviating free radical damage and diseases显示文摘Ever since molecular hydrogen was first reported as a hydroxyl radical scavenger in 200Z the beneficial effect of hydrogen was documented in more than 170 disease models and human diseases including ischemia/reperfusion injury,metabolic syndrome,inflammation,and cancer.All these pathological damages are concomitant with overproduction of reactive oxygen species(ROS)where molecular hydrogen has been widely demonstrated as a selective antioxidant.Although it is difficult to construe the molecular mechanism of hydrogen's biomedical effect,an increasing number of studies have been helping us draw the picture clearer with days passing by.In this review,we summarized the current knowledge on systemic and cellular modulation by hydrogen treatment.We discussed the antioxidative,anti-inflammatory,and anti-apoptosis effects of hydrogen,as well as its protection on mitochondria and the endoplasmic reticulum,regulation of intracellular signaling pathways,and balancing of the immune cell subtypes.We hope that this review will provide organized information that prompts further investigation for in?depth studies of hydrogen effect. | Geru Tao Guohua Song Shucun Qin | 2019 | Acta Biochimica et Biophysica Sinica2019，51，12： | 18 |
| 18 | Investigation of scale inhibition mechanisms based on the effect of scale inhibitor on calcium carbonate crystal forms显示文摘To probe the scale inhibition mechanisms,calcium carbonate scale occurring before and after the ad- dition of scale inhibitors was collected.The results from scale SEM confirm that,without scale inhibitor, calcium carbonate scale shows rhombohedron and hexagon,which are the characteristic feathers of calcite.After addition of inhibitors,morphology of scale is changed,and the more efficient the scale inhibitor is,the more greatly the morphology is modified.To elucidate the scale constitute,they were further analyzed by FT-IR,XRD.Besides calcite,vaterite and aragonite occur in calcium carbonate scale after addition of inhibitors,and the higher scale inhibition efficiency is,the more vaterite presents in scale.It can be concluded that the alteration of morphology is ascribed to the change of crystal form. There are three stages in the crystallizing process including occurrence and disappearing of unstable phase,occurrence and disappearing of metastable phase,development of stable phase.Without scale inhibitors,metastable phases usually transform into stable phase,thus the main constitute of formed scale is calcite.When scale inhibitors are added,both formation and transformation of metastable phases are inhibited,which results in the occurrence of aragonite and vaterite.From the fact that more vaterite presents in scale with a more efficient scale inhibitor added,we can see that the function of scale inhibitor is realized mainly by controlling the crystallizing process at the second stage. | ZHANG GuiCai GE JiJiang SUN MingQin PAN BinLin MAO Tao SONG ZhaoZheng | 2007 | Science China Chemistry2007，50，1： | 17 |

Native-PAGE shows that the purified proteins from LaCl3-, CeCl3- treated spinach have not only a band of Rubisco (560 kD), but also a band of about 1100 kD, about twice distant from Rubisco, which might be a complex of Rubisco and Rubisco activase. The purified enzyme activities from LaCl3-, CeCl3-treated spinach are 1.8 and 2.8 times that of the control,the intensities of absorption and fluorescence are sig- nificantly higher than that of the purified Rubisco from the control, and the total sulfhydryl groups and available sulfhydryl groups are 36—39 –SH per mol enzyme, 14—25 –SH per mol enzyme more than those of the purified Rubisco from the control, respectively. The CD spectra show that the secondary structure of the purified enzyme from LaCl3-, CeCl3 -treated spinach is very dif- ferent from the control. The enzyme activities from LaCl3-, CeCl3- treated spinach in vivo are 1.5 and 1.9 times those of the control. | HONG Fashui1, LIU Chao1, ZHENG Lei1, WANG Xuefeng1, WU Kang1, SONG Weiping1, Lü Shipeng1, TAO Ye2 & ZHAO Guiwen3 1.
