| 1 | Extreme climate events over northern China during the last 50 years显示文摘Climate extremes for agriculture-pasture transitional zone, northem China, are analyzed on the basis of daily mean temperature and precipitation observations for 31 stations in the period 1956-2001. Analysis season for precipitation is May-September, i.e., the rainy season. For temperature is the hottest three months, i.e., June through August. Heavy rain events, defined as those with daily precipitation equal to or larger than 50 mm, show no significant secular trend. A jump-like change, however, is found occurring in about 1980. For the period 1980-1993, the frequency of heavy rain events is significantly lower than the previous periods. Simultaneously, the occurring time of heavy rains expanded, commencing about one month early and ending one month later. Long dry spells are defined as those with longer than 10 days without rainfall. The frequency of long dry spells displays a significant (at the 99% confidence level) trend at the value of +8.3% /10a. That may be one of the major causes of the frequent droughts emerging over northern China during the last decades. Extremely hot and low temperature events are defined as the uppermost 10% daily temperatures and the lowest 10% daily temperatures, respectively. There is a weak and non-significant upward trend in frequency of extremely high temperatures from the 1950s to the mid-1990s. But the number of hot events increases as much as twice since 1997. That coincides well with the sudden rise in mean summer temperature for the same period. Contrary to that, the fiequency of low temperature events have been decreasing steadily since the 1950s, with a significant linear trend of-15%/10a. | HANHui GONGDaoyi | 2003 | Journal of Geographical Sciences2003，13，4： | 18 |
| 2 | Laparoscopy-assisted D2 radical distal gastrectomy for gastric cancer (Billroth Ⅱ anastomosis)显示文摘Laparoscopic radical gastrectomy has been increasingly applied in China. However, how to reduce surgery-related trauma, shorten operative time and achieve the long-term prognosis equal to the conventional open surgery is still hot research topics. Along with the change in learning curve and the optimization of endoscopic techniques, laparoscopic lymph node dissection can achieve or even exceed the extent that can be achieved in open surgery. Therefore, it has gradually replaced the conventional digestive tract reconstruction using an auxiliary incision. By completing the laparoscopic digestive tract reconstruction with EndoGIA, we describe the laparoscopy-assisted D2 radical distal gastrectomy for gastric cancer (Billroth Ⅱ anastomosis). | Hanhui Yao Qiang Huang Zhiqiang Zhu Wei Liang | 2013 | Chinese Journal of Cancer Research2013，25，4： | 10 |
| 3 | Yttrium aluminum garnet (Y_3A_(l5)O_(12)) nanopowders synthesized by the chemical method显示文摘The homogeneously dispersed, less agglomerated YAG nanopowders are synthesized by the citrate-gel method followed by low-temperature self-propagating combustion reaction, using Y2O3, Al(NO3)3?9H2O and citric acid as starting materials. This method effectively solves the problems caused by solid-state reaction at high temperature and the hard ag-glomerates brought by the chemical precipitation method. The powders are characterized by TG-DTA, XRD, FT-IR and TEM respectively. The experiments show that the forming temperature of YAG crystal phase is 850°C and the pseudo-YAG crystalline appears during the calcination and transforms to pure YAG at 1050°C. The powders with sizes less than 50 nm are observed by TEM micrography, which is consistent with the result calculated by Scherrer’s formula. The powders consist of single grains. | ZHANGHuasha SUChunhui HANHui HOUZhaoxia WANGGuangzhao | 2005 | Rare Metals2005，24，2： | 6 |
| 4 | Encapsulating metal organic framework into hollow mesoporous carbon sphere as efficient oxygen bifunctional electrocatalyst显示文摘Applying metal organic frameworks(MOFs) in electrochemical systems is a currently emerging field owing to the rich metal nodes and highly specific surface area of MOFs. However, the problems for MOFs that need to be solved urgently are poor electrical conductivity and low ion transport. Here we present a facile in situ growth method for the rational synthesis of MOFs@hollow mesoporous carbon spheres(HMCS)yolk–shell-structured hybrid material for the first time. The size of the encapsulated Zeolitic Imidazolate Framework-67(ZIF-67) is well controlled to 100 nm due to the spatial confinement effect of HMCS, and the electrical conductivity of ZIF-67 is also increased significantly. The ZIF@HMCS-25% hybrid material obtained exhibits a highly efficient oxygen reduction reaction activity with 0.823 V(vs. reversible hydrogen electrode) half-wave potential and an even higher kinetic current density(JK= 13.8 m A cm-2) than commercial Pt/C. ZIF@HMCS-25% also displays excellent oxygen evolution reaction performance and the overpotential of ZIF@HMCS-25% at 10 m A cm-2 is 407 m V. In addition, ZIF@HMCS-25% is further employed as an air electrode for a rechargeable Zn–air battery, exhibiting a high power density(120.2 m W cm-2 at 171.4 m A cm-2) and long-term charge/discharge stability(80 h at 5 m A cm-2). This MOFs@HMCS yolk–shell design provides a versatile method for the application of MOFs as electrocatalysts directly. | Wanfeng Xiong Hongfang Li Hanhui You Minna Cao Rong Cao | 2020 | National Science Review2020，7，3： | 6 |

| 7 | LES/FDF simulation of particle dispersion in a gas-particle two phase plane wake flow显示文摘A filtered density function (FDF) transport equation was derived for the fluid velocity seen by the particles in gas-particle two-phase flow. An LES/FDF simulation of a two-phase plane wake flow was carried out. The simulation results were compared with both the experimental photograph and the simulation results without using the FDF model, and proved that the LES/FDF model can clearly improve the spatial dispersion of the particle phase. | JIN HanHui CHEN SuTao CHEN LiHua FAN JianRen | 2009 | Science China(Technological Sciences)2009，52，10： | 4 |
| 8 | Efficient base editing in G/C-rich regions to model androgen insensitivity syndrome显示文摘Dear Editor, Most disease-associated genomic mutations are base substitutions and approximately half of pathogenic human single nucleotide polymorphisms (SNPs)are related to C-to-T substitutions in the ClinVar database.Base editors (BEs),which combine Casg-DIOA nickase and APOBEC (apolipoprotein B mRNA editing enzyme,catalytic polypeptide-like)or AID (activation-induced deaminase)cytidine deaminase family members, have been successfully applied to mediate C-to-T conversion in vitro and in vivo, providing a powerful tool to model or repair diseaserelated human SNPs. | Jianan Li Zhen Liu Shisheng Huang Xiao Wang Guanglei Li Yuting Xu Wenxia Yu Shanshan Chen Yu Zhang Hanhui Ma Zunfu Ke Jia Chen Qiang Sun Xingxu Huang | 2019 | Cell Research2019，29，2： | 3 |

| 10 | Radiation balance and the response of albedo to environmental factors above two alpine ecosystems in the eastern Tibetan Plateau显示文摘Understanding the energy balance on the Tibetan Plateau is important for better prediction of global climate change. To characterize the energy balance on the Plateau, we examined the radiation balance and the response of albedo to environmental factors above an alpine meadow and an alpine wetland surfaces in the eastern Tibetan Plateau, using 2014 data. Although our two sites belong to the same climatic background, and are close geographically, the annual incident solar radiation at the alpine meadow site(6,447 MJ/(m2·a)) was about 1.1 times that at the alpine wetland site(6,012 MJ/(m2·a)),due to differences in the cloudiness between our two sites. The alpine meadow and the alpine wetland emitted about 38%and 42%, respectively, of annual incident solar radiation back into atmosphere in the form of net longwave radiation; and they reflected about 22% and 18%, respectively, of the annual incident solar radiation back into atmosphere in the form of shortwave radiation. The annual net radiation was 2,648 and 2,544 MJ/(m2·a) for the alpine meadow site and the alpine wetland site, respectively, accounting for only about 40% of the annual incident solar radiation, significantly lower than the global mean. At 30-min scales, surface albedo exponentially decreases with the increase of the solar elevation angle; and it linearly decreases with the increase of soil-water content for our two sites. But those relationships are significantly influenced by cloudiness and are site-specific. | ShaoYing Wang Yu Zhang ShiHua Lyu LunYu Shang YouQi Su HanHui Zhu | 2017 | Research in Cold and Arid Regions2017，9，2： | 2 |

| 13 | Solid-state synthesis of Li[Li_(0.2)Mn_(0.56)Ni_(0.16)Co_(0.08)]O_2 cathode materials for lithium-ion batteries显示文摘Layered Li|Li_(0.2)Mn_(0.56)Ni_(0.16)Co_(0.08]O_2 cathode materials were synthesized via a solid-state reaction for Liion batteries,in which lithium hydroxide monohydrate,manganese dioxide,nickel monoxide,and cobalt monoxide were employed as metal precursors.To uncover the relationship between the structure and electrochemical properties of the materials,synthesis conditions such as calcination temperature and time as well as quenching methods were investigated.For the synthesized Li[Li_(0.2)Mn_(0.56)Ni_(0.16)Co_(0.08)]O_2materials,the metal components were found to be in the form of Mn^(4+),Ni^(2+),and Co^(3+),and their molar ratio was in good agreement with stoichiometric ratio of 0.56:0.16:0.08.Among them,the one synthesized at 800 C for 12 h and subsequently quenched in air showed the best electrochemical performances,which had an initial discharge specific capacity and coulombic efficiency of 265.6 mAh/g and 84.0%,respectively,and when cycled at 0.5,1,and 2C,the corresponding discharge specific capacities were 237.3,212.6.and 178.6 mAh/g,respectively.After recovered to 0.1 C rate,the discharge specific capacity became259.5 mAh/g and the capacity loss was only 2.3% of the initial value at 0.1 C.This work suggests that the solid-state synthesis route is easy for preparing high performance Li[Li_(0.2)Mn_(0.56)Ni_(0.16)Co_(0.08)]O_2 cathode materials for Li-ion batteries. | Wenjuan Hao Hanhui Zhan Han Chen Yanhong Wang Qiangqiang Tan Fabing Su | 2014 | Particuology2014，12，4： | 1 |

| 20 | Enhancing prime editing efficiency and flexibility with tethered and split pegRNAs显示文摘Dear Editor,Most human genetic diseases arise from mutations such as insertion,deletion,or point mutations(Landrum et al.,2016).CRISPRCas system has been repurposed to correct pathogenic mutations in a variety of genetic diseases(Choi et al.,2022).There are many concerns about using CRISPR-mediated double-stranded DNA breaks(DSBs)for therapeutic purposes,primarily due to off-targeted mutations(Kosicki et al.,2018).Nevertheless,base editing cannot correct deletions,insertions,or some point mutations such as transversion mutations.Prime editing has its advantages of precisely correct point mutations,small insertions,or deletions in animal cells(Anzalone et al.,2019)and plants(Lin et al.,2020).However,prime editing efficiency varies among genomic sites or cell types(Chen et al.,2021;Nelson et al.,2022). | Ying Feng Siyuan Liu Qiqin Mo Pengpeng Liu Xiao Xiao Hanhui Ma | 2023 | Protein & Cell2023，14，4： | 1 |
