| 1 | Progress and recent trend in MILD combustion显示文摘Moderate or intense low oxygen dilution(MILD)combustion plays a significant role in the mitigation of combustion-generated pollutants and greenhouse gases whilst meeting thermal efficiency needs.However,due to the lack of the fundamental knowledge on this combustion,there is a misconception that MILD combustion should be established by high preheating of the air,which has limited its application.Our research and development on this combustion has been performed for several years. We have found that the requirements for establishing the MILD combustion are more relaxed than previously.It is also revealed that this combustion of different type,i.e.,non-premixed,partially premixed and fully premixed,can be achieved by firing various fuels(i.e.,gaseous,liquid and solid fuels).It is suggested that the application of the MILD combustion can be expanded significantly.The present review summarizes the progress and recent trend made in the R&D of this combustion and recommends further fundamental studies for improving our knowledge and widening its applications. | LI PengFei MI JianChun DALLY B B WANG FeiFei WANG Lin LIU ZhaoHui CHEN Sheng ZHENG ChuGuang | 2011 | Science China(Technological Sciences)2011，54，2： | 31 |
| 2 | Age-related rhesus macaque models of COVID-19显示文摘Background:Since December 2019,an outbreak of the Corona Virus disease 2019(COVID-19)caused by severe acute respiratory syndrome coronavirus(SARS-CoV-2)in Wuhan,China,has become a public health emergency of international concern.The high fatality of aged cases caused by SARS-CoV-2 was a need to explore the possible age-related phenomena with non-human primate models.Methods:Three 3-5 years old and two 15 years old rhesus macaques were intratracheally infected with SARS-CoV-2,and then analyzed by clinical signs,viral replication,chest X-ray,histopathological changes and immune response.Results:Viral replication of nasopharyngeal swabs,anal swabs and lung in old monkeys was more active than that in young monkeys for 14 days after SARS-CoV-2 challenge.Monkeys developed typical interstitial pneumonia characterized by thickened alveolar septum accompanied with inflammation and edema,notably,old monkeys exhibited diffuse severe interstitial pneumonia.Viral antigens were detected mainly in alveolar epithelial cells and macrophages.Conclusion:SARS-CoV-2 caused more severe interstitial pneumonia in old monkeys than that in young monkeys.Rhesus macaque models infected with SARS-CoV-2 provided insight into the pathogenic mechanism and facilitated the development of vaccines and therapeutics against SARS-CoV-2 infection. | Pin Yu Feifei Qi Yanfeng Xu Fengdi Li Peipei Liu Jiayi Liu Linlin Bao Wei Deng Hong Gao Zhiguang Xiang Chong Xiao Qi Lv Shuran Gong Jiangning Liu Zhiqi Song Yajin Qu Jing Xue Qiang Wei Mingya Liu Guanpeng Wang Shunyi Wang Haisheng Yu Xing Liu Baoying Huang Wenling Wang Li Zhao Huijuan Wang Fei Ye Weimin Zhou Wei Zhen Jun Han Guizhen Wu Qi Jin Jianwei Wang Wenjie Tan Chuan Qin | 2020 | Animal Models and Experimental Medicine2020，3，1： | 22 |
| 3 | Effect of different concentrations of surfactant on the wettability of coal by molecular dynamics simulation显示文摘Anionic surfactant sodium dodecyl benzene sulfonate(SDBS)at varying concentrations was selected to investigate the influence on the wettability of Zhaozhuang Coal by molecular dynamics simulation.Six groups of water/surfactant/coal systems with different concentrations were constructed.The influence of surfactant with different concentrations on the wettability of coal was concluded by analyzing various properties from the energetic behaviors to the dynamic characteristics.The results show that the interfacial tension decreases sharply and then rises slowly with the increase of SDBS surfactant concentration,obtaining that surfactants can obviously reduce the interfacial tension.The surfactant molecules could be detected at the water/coal interface through analyzing the system’s relative concentration distribution.In addition,the difference in the wettability of surfactants on coal surfaces is caused by the spatial distribution differences of alkyl chains and the benzene ring of the surfactant molecules.And the negative interaction energy between SDBS and the coal surface indicates that adsorption process is spontaneous.Furthermore,it is of great practical significance for improving the dust reduction effect and reducing the disaster of coal dust by exploring the effects of surfactant molecules on the wettability of coal. | Junqing Meng Feifei Yin Shichao Li Ruquan Zhong Zeyuan Sheng Baisheng Nie | 2019 | International Journal of Mining Science and Technology2019，29，4： | 20 |
| 4 | Characterization of drug responses of mini patient-derived xenografts in mice for predicting cancer patient clinical therapeutic response显示文摘Background:Patient-derived organoids and xenografts(PDXs)have emerged as powerful models in functional diag-nostics with high predictive power for anticancer drug response.However,limitations such as engraftment failure and time-consuming for establishing and expanding PDX models followed by testing drug efficacy,and inability to subject to systemic drug administration for ex vivo organoid culture hinder realistic and fast decision-making in selecting the right therapeutics in the clinic.The present study aimed to develop an advanced PDX model,namely MiniPDX,for rapidly testing drug efficacy to strengthen its value in personalized cancer treatment.Methods:We developed a rapid in vivo drug sensitivity assay,OncoVee®MiniPDX,for screening clinically relevant regimens for cancer.In this model,patient-derived tumor cells were arrayed within hollow fiber capsules,implanted subcutaneously into mice and cultured for 7 days.The cellular activity morphology and pharmacokinetics were systematically evaluated.MiniPDX performance(sensitivity,specificity,positive and negative predictive values)was examined using PDX as the reference.Drug responses were examined by tumor cell growth inhibition rate and tumor growth inhibition rate in PDX models and MiniPDX assays respectively.The results from MiniPDX were also used to evaluate its predictive power for clinical outcomes.Results:Morphological and histopathological features of tumor cells within the MiniPDX capsules matched those both in PDX models and in original tumors.Drug responses in the PDX tumor graft assays correlated well with those in the corresponding MiniPDX assays using 26 PDX models generated from patients,including 14 gastric cancer,10 lung cancer and 2 pancreatic cancer.The positive predictive value of MiniPDX was 92%,and the negative predictive value was 81%with a sensitivity of 80%and a specificity of 93%.Through expanding to clinical tumor samples,Min-iPDX assay showed potential of wide clinical application.Conclusions:Fast in vivo MiniPDX assay based on capsule implantation was developed-to assess drug responses of both PDX tumor grafts and clinical cancer specimens.The high correlation between drug responses of paired MiniPDX and PDX tumor graft assay,as well as translational data suggest that MiniPDX assay is an advanced tool for personalized cancer treatment. | Feifei Zhang Wenjie Wang Yuan Long Hui Liu Jijun Cheng Lin Guo Rongyu Li Chao Meng Shan Yu Qingchuan Zhao Shun Lu Lili Wang Haitao Wang Danyi Wen | 2018 | Cancer Communications2018，38，1： | 20 |

| 6 | Springback prediction of thick-walled high-strength titanium tube bending显示文摘Signifcant springback occurs after tube rotary-draw-bending(RDB),especially for a high-strength Ti–3Al–2.5V tube(HSTT) due to its high ratio of yield strength to Young's modulus.The combination scheme of explicit and implicit is preferred to predict the springback.This simulation strategy includes several numerical parameters,such as element type,number of elements through thickness(NEL),element size,etc.However,the influences of these parameters on springback prediction accuracy are not fully understood.Thus,taking the geometrical specifcation9.525 mm · 0.508 mm of a HSTT as the objective,the effects of numerical parameters on prediction accuracy and computation effciency of springback simulation of HSTT RDB are investigated.The simulated springback results are compared with experimental ones.The main results are:(1) solid and continuum-shell elements predict the experimental results well;(2) for C3D8R elements,NEL of at least 3 is required to obtain reliable results and a relative error of 29% can occur as NEL is varied in the range of 1–3;(3) specifying damping factor typically works well in Abaqus/Emplicit simulation of springback and the springback results are sensitive to the magnitude of damping factor.In addition,the explanations of the effect rules are given and a guideline is added. | Song Feifei Yang He Li Heng Zhan Mei Li Guangjun | 2013 | Chinese Journal of Aeronautics2013，26，5： | 15 |
| 7 | Generation of B Cell-Deficient Pigs by Highly Efficient CRISPR/Cas9-Mediated Gene Targeting显示文摘Generating B cell-deficient mutant is the first step to produce human antibody repertoires in large animal models. In this study, we applied the clustered regularly interspaced short palindromic repeat(CRISPR)/CRISPR-associated(Cas) system to target the JHregion of the pig Ig M heavy chain gene which is crucial for B cell development and differentiation. Transfection of Ig M-targeting Cas9 plasmid in primary porcine fetal fibroblasts(PFFs) enabled inducing gene knock out(KO) in up to 53.3% of colonies analyzed, a quarter of which harbored biallelic modification, which was much higher than that of the traditional homologous recombination(HR). With the aid of somatic cell nuclear transfer(SCNT) technology, three piglets with the biallelic Ig M heavy chain gene mutation were produced. The piglets showed no antibody-producing B cells which indicated that the biallelic mutation of the Ig M heavy chain gene effectively knocked out the function of the Ig M and resulted in a B cell-deficient phenotype. Our study suggests that the CRISPR/Cas9 system combined with SCNT technology is an efficient genome-editing approach in pigs. | Fengjiao Chen Ying Wang Yilin Yuan Wei Zhang Zijian Ren Yong Jin Xiaorui Liu Qiang Xiong Qin Chen Manling Zhang Xiaokang Li Lihua Zhao Ze Li Zhaoqiang Wu Yanfei Zhang Feifei Hu Juan Huang Rongfeng Li Yifan Dai | 2015 | Journal of Genetics and Genomics2015，42，8： | 15 |
| 8 | Bird watching in China reveals bird distribution changes显示文摘Using China Bird Report(2003-2007) as data source in combination with descriptions about bird habitats,we built up the China Bird Watching Database.We also developed spherical GIS software 'Global Analyst' to create the point-based database which contains accurate spatial-temporal information.The China Bird Watching Database can reflect the achievement of Chinese bird watchers and complement the basic knowledge of bird distribution.Now a total of 30936 records from 17 Orders,70 Families and 1078 Species of 5 years are included in the database,representing over 80% of all bird species in China.Till 2007,the geographic coverage has encompassed all provincial level administrative districts in China,with the exception of Hong Kong and Taiwan.The China Bird Watching Database also recorded a group of species which are additions at national and provincial levels,including 14 species which are additions to the national checklist and 109 species which appeared outside their original distributions.Comparing the new records with their original distributions,we found the trend that species move to higher latitude and higher elevation regions and some species of waterfowls in Xinjiang Uygur Autonomous Region,including a suite of rare seabirds in the China's Mainland.The majority of bird watchers come from the Eastern Region of China,but their covering range is spreading northwest.At the same time,we appeal to adopting a suite of new technologies for observation,and building up sharing platform of bird watching data to capture the distribution dynamics of birds in China and provide a direct foundation for bird conservation. | LI XueYan LIANG Lu GONG Peng LIU Yang LIANG FeiFei | 2013 | Chinese Science Bulletin2013，58，6： | 13 |
| 9 | Controlling angular dispersions in optical metasurfaces显示文摘Although metasurfaces have shown great potential for manipulating light,most previously realized meta-devices suffer from uncontrolled angular dispersions,making them unfavorable for many applications.Here,we propose a general strategy to realize optical metasurfaces with desired angular dispersions based on carefully controlling both the near-field couplings between meta-atoms and the radiation pattern of a single meta-atom.Utilizing such a strategy,we experimentally demonstrate a series of optical meta-devices with predesigned angular dispersions,including two incident-angle-insensitive absorbers,one incident-angle-selective absorber,and one multifunctional meta-polarizer whose functionality changes from a perfect mirror to a half-waveplate as the excitation angle varies.Finally,we design a gradient meta-device using meta-atom arrays with purposely controlled angular dispersions and numerically demonstrate that it can exhibit distinct wavefront-control functionalities when illuminated at different incident angles.Our findings establish a new platform for achieving angle-multiplexed functional meta-devices,significantly expanding the wave-manipulation capabilities of optical metasurfaces. | Xiyue Zhang Qi Li Feifei Liu Meng Qiu Shulin Sun Qiong He Lei Zhou | 2020 | Light(Science & Applications)2020，9，1： | 11 |
| 10 | Paleomagnetic results of Late Paleozoic rocks from northern Qiangtang Block in Qinghai-Tibet Plateau, China显示文摘Tectonic evolution of the Tethys and the boundary between the Gondwanaland and the Eurasia during the Carboniferous and Permian remain hotly debated. Qiangtang region in the Qinghai-Tibet Plateau may be a key place to study these problems. A paleomagnetic study was conducted on the Late Paleozoic rocks in the northern Qiangtang region (33.7°N, 86.7°W), Tibet. Two sites (21 samples) in the Upper Carboniferous, eleven sites (101 samples) in the Permian, and two sites (16 samples) in the Lower Triassic were investigated. The rock magnetic data revealed hematite and magnetite as the main magnetic carriers. In stepwise thermal demagnetization and/or combined alternating field (AC) demagnetization, two characteristic components in the majority of the samples were identified as (1) the Low-temperature Component (LTC), characterized by northerly decli- nation and moderate to steep inclination, corresponding to a pole position overlay with the present North Pole. A minority of the samples present single component, and their directions are the same as (2) the High-temperature Component (HTC) of double components. The combined single-component and HTC data of the Permian can pass the R-test at 95% level and the F-test at 99% level, as well as the BC-test. The pole position from the Late Carboniferous is at 31.8°S, 45.7°E with dp=2.1, dm=3.9, that from the Early and Middle (Late) Permian is at 31.7°S, 46.8°E with dp=9.2, dm=16.9 (34.4°N, 54.1°E with dp=6.9, dm=12.5) respectively, and that from the Early Triassic is at 16.9°S, 22.5°E with dp=4.9, dm=9.2. These pole positions are different from the other poles for the Qiangtang Block, which suggests the single-component and HTC directions are probably a primary magnetization and the northern Qiangtang Block was paleogeographically situated at low latitudes in the Northern Hemisphere in the Late Paleozoic. | CHENG Xin WU HanNing GUO Qiang HOU BaoNing XIA LingYan WANG HaiJun DIAO ZongBao HUO FeiFei JI WenHua LI RongShe CHEN ShouJian ZHAO ZhenMing LIU XiaoJi | 2012 | Science China Earth Sciences2012，55，1： | 9 |
| 11 | Review of Remotely Sensed Imagery Classification Patterns Based on Object-oriented Image Analysis显示文摘With the wide use of high-resolution remotely sensed imagery, the object-oriented remotely sensed informa- tion classification pattern has been intensively studied. Starting with the definition of object-oriented remotely sensed information classification pattern and a literature review of related research progress, this paper sums up 4 developing phases of object-oriented classification pattern during the past 20 years. Then, we discuss the three aspects of method- ology in detail, namely remotely sensed imagery segmentation, feature analysis and feature selection, and classification rule generation, through comparing them with remotely sensed information classification method based on per-pixel. At last, this paper presents several points that need to be paid attention to in the future studies on object-oriented RS in- formation classification pattern: 1) developing robust and highly effective image segmentation algorithm for multi-spectral RS imagery; 2) improving the feature-set including edge, spatial-adjacent and temporal characteristics; 3) discussing the classification rule generation classifier based on the decision tree; 4) presenting evaluation methods for classification result by object-oriented classification pattern. | LIU Yongxue LI Manchun MAO Liang XU Feifei HUANG Shuo | 2006 | Chinese Geographical Science2006，16，3： | 9 |
| 12 | Wnt/β-catenin signaling in cancers and targeted therapies显示文摘Wnt/β-catenin signaling has been broadly implicated in human cancers and experimental cancer models of animals.Aberrant activation of Wnt/β-catenin signaling is tightly linked with the increment of prevalence,advancement of malignant progression,development of poor prognostics,and even ascendence of the cancer-associated mortality.Early experimental investigations have proposed the theoretical potential that efficient repression of this signaling might provide promising therapeutic choices in managing various types of cancers.Up to date,many therapies targeting Wnt/β-catenin signaling in cancers have been developed,which is assumed to endow clinicians with new opportunities of developing more satisfactory and precise remedies for cancer patients with aberrant Wnt/β-catenin signaling. | Fanyuan Yu Changhao Yu Feifei Li Yanqin Zuo Yitian Wang Lin Yao Chenzhou Wu Chenglin Wang Ling Ye | 2021 | Signal Transduction and Targeted Therapy2021，6，9： | 8 |
| 13 | Allele-defined genome reveals biallelic differentiation during cassava evolution显示文摘Dear Editor,Generation of heterozygous genomes by hybridization between or within species can help maintain plant diversity and serve as a potential source of new species(Baek et al.,2018).Moreover,genomic heterozygosity is associated with genomic coadaptation,developmental stability,and heterosis.Accurate definition of alleles in haplotypes is necessary to precisely characterize allelic variation controlling agriculturally important traits(Shi et al.,2019).Currently,most released genomes have mosaic assembly of haplotypes due to random selection or collapse of alleles during genome assembly(Shi et al.,2019),which masked allelic variation and functional differentiation of divergent alleles in heterozygous species. | Wei Hu Changmian Ji Haitao shi Zhe Liang Zehong Ding Jianqiu Ye Wenjun Ou Gang Zhou Weiwei Tie Yan Yan Jinghao Yang Xiaoying Yang Yunxie Wei Zhiqiang Jin Jianghui Xie Ming Peng Wenquan Wang Anping Guo Biyu Xu Jianchun Guo Songbi Chen Liming Ma Mingcheng Wang Yang Zhou Xiaolong Li Ruoxi Li Siyi Guo Xinhui Xiao Zhongqing Wan Feifei An Jie Zhang Qingyun Leng Yin Li Ray Ming Kaimian Li | 2021 | Molecular Plant2021，14，6： | 8 |
| 14 | A GATA-type transcription factor AcAREB for nitrogen metabolism is involved in regulation of cephalosporin biosynthesis in Acremonium chrysogenum显示文摘In filamentous fungi,nitrogen metabolism is repressed by GATA-type zinc finger transcription factors.Nitrogen metabolite repression has been found to affect antibiotic production,but the mechanism is still poorly understood.AcareB,encoding a homologue of fungal GATA-type regulatory protein,was cloned from Acremonium chrysogenum.Gene disruption and genetic complementation demonstrated that AcareB plays a key role in utilization of ammonium,glutamine and urea.In addition,significant reduction of cephalosporin production in the AcareB disruption mutant indicated that AcareB is important for cephalosporin production.In consistence with it,the transcriptional level of cephalosporin biosynthetic genes was significantly decreased in the AcareB disruption mutant.Electrophoretic mobility shift assay showed that AcAREB directly bound to the intergenic regions of pcbAB-pcbC,cefD1-cefD2 and cefEF-cefG.Sequence analysis showed that all the AcAREB binding sites contained the consensus GATA elements.AcareB is negatively autoregulated during cephalosporin production.Moreover,another GATA zinc-finger protein encoded by AcareA positively regulates the transcription of AcareB.However,AcareB does not regulate the transcription of AcareA.These results indicated that AcAREB plays an important role in both regulation of nitrogen metabolism and cephalosporin production in A.chrysogenum. | Feifei Guan Yuanyuan Pan Jinyang Li Gang Liu | 2017 | Science China(Life Sciences)2017，60，9： | 8 |
| 15 | Response of Pinus taiwanensis growth to climate changes at its southern limit of Daiyun Mountain, China's Mainland Fujian Province显示文摘The Pinus taiwanensis trees of a Chinese endemic species form pure forests at infertile sites in humid subtropical China, which can aid soil reservation and ecological resiliency at such sites. Herein, we used dendrochronological methods to investigate the growth patterns and their relationship with climate by analyzing 158 cores of 79 P. taiwanensis trees at 4 sites in their southernmost distribution in China's Mainland at Daiyun Mountain in Fujian Province. Tree growths at sites with favorable conditions generally showed an age-related growth trend, which decreased from approximately 5 mm to 0.5 mm in about a century. Trees in moderately stressed environments established high growth in their juvenile periods but were highly susceptible to environmental stresses such as a sharp growth decline in the 1990 s. The temperature in February and the moisture in July are the major limiting factors for most of the tree growths, except for a few extremely stressed P. taiwanensis trees. The growth of the dwarf P. taiwanensis trees, with all ring diameters of the first 20 years less than 4 mm, is mainly limited by the dry climate in May. Under the potential future warming trend, drought stress can be particularly threatening to these dwarf P. taiwanensis trees, which are likely to be the germplasm resources for this species in this region. | CHEN Dan FANG KeYan LI YingJun DONG ZhiPeng ZHANG Yu ZHOU FeiFei | 2016 | Science China Earth Sciences2016，59，2： | 6 |
| 16 | Geochronology and geochemistry of mafic dykes in the Helanshan complex: Implications for Mesozoic tectonics in the North China Craton显示文摘The Helanshan tectonic belt(HTB) is a major tectonic divide between the Alxa and Ordos blocks in the North China Craton. The geochronology and petrogenesis of the mafic dykes in the northern HTB are keys to understanding the tectonic evolution of this belt. The mafic dykes, intruded into the Neoarchean-Paleoproterozoic metamorphic basement, are mainly composed of diabase with a mineral assemblage of plagioclase(45%-60%), pyroxene(25%-35%), minor quartz and Fe-Ti oxides. The LA-ICPMS U-Pb analysis of zircon grains from representative dykes yield a weighted mean age of 206 ± 1.9 Ma, which represents the crystallization age of the dyke. The diabases show high contents of Fe_2 O_3~T(11.88-17.55 wt.%), low contents of SiO_2(45.65-50.95 wt.%) and MgO(3.31-5.50 wt.%) with low Mg#(=100×MgO/(MgO + FeO) atomic ration) of 33-44. They are characterized by enrichment of light rare earth elements(LREEs) and large ion lithophile elements(LILEs)(e.g., Rb, Ba and Pb), and slight depletion of high field strength elements(HFSEs). These features suggest that the magma has undergone extensive fractionation of olivine and pyroxene but only minor crustal contamination during its evolution. Their high Sm contents and La/Sm ratios, and low Sm/Yb ratios indicate that magma from which the dykes formed was derived from low degree(about 5%) partial melting of an enriched garnet + spinel lherzolite mantle source. Together with regional geology, these geochemical and geochronological data suggest that the mafic dykes in the HTB were formed in an intracontinental extensional setting during the late Triassic. | Zhenghui Li Xiaoming Liu Yunpeng Dong M.Santosh Feifei Zhang Jie Xu | 2018 | Geoscience Frontiers2018，9，6： | 6 |
| 17 | Application of an analytic hierarchy process to hydrocarbon accumulation coefficient estimation显示文摘The hydrocarbon accumulation coefficient is a key parameter in resources evaluation by genetic techniques. Methods of obtaining its value scientifically have always been an important factor influencing evaluation credibility. In this paper, the hydrocarbon accumulation system is evaluated quantitatively by establishing a hierarchy structure model based on an analytical hierarchy process. The hydrocarbon accumulation system of a higher exploration degree is selected as a calibration area and its hydrocarbon accumulation coefficient can be calculated using methods of hydrocarbon generation potential and reservoir-scale sequence. The hydrocarbon accumulation coefficient of a petroleum accumulation system can be gained by analogy of reservoir forming comprehensive evaluation results with the calibration area. The hydrocarbon accumulation coefficient of each petroleum accumulation system in the upper reservoir-forming combination of the Liaohe Western Sag can be obtained with this method. Practice shows that using the analytical hierarchy process to quantitatively evaluate the hydrocarbon accumulation system and then quantitatively predict the hydrocarbon accumulation coefficient decreases the influence of human factors in resources evaluation, and makes the resources assessment more objective and closer to the actual geological condition. | Gao Yongjin Liu Lifeng Liu Huimin Zheng Feifei Wu Li Zhou Jingjing Qu Dongfang | 2010 | Petroleum Science2010，7，3： | 5 |
| 18 | Cathepsin B-responsive nanodrug delivery systems for precise diagnosis and targeted therapy of malignant tumors显示文摘The tumor microenvironment(TME)significantly influences cancer evolution and therapeutic efficacy.Targeting biofunctional molecules to the TME has long been appreciated as a means of raising local drug concentrations and reducing systemic toxicities.The booming nanotechnology field has realized the importance of cathepsin B to derive a variety of intelligent enzyme-responsive nanosized drug delivery systems(nanoDDS)to improve treatment responses and clinical outcomes.In this tutorial review,after introducing the molecular structure and physiological/pathological functions of cathepsin B,the outstanding achievements of cathepsin B-responsive nanoplatforms in the precise diagnosis,targeted therapy,and synergistic theranostics of malignant tumors are systematically described.Finally,the challenges of enzyme-substrate incompatibility,low diagnostic sensitivity,mass production and biocompatibility of multifunctional nanoDDS are considered in order to successfully promote them to clinical applications. | Yanan Li Ting Mei Shupeng Han Tao Han Yongbing Sun Hui Zhang Feifei An | 2020 | Chinese Chemical Letters2020，31，12： | 5 |
| 19 | A novel comparative molecule/pseudo receptor interaction analysis显示文摘Comparative molecule/pseudo receptor interaction analysis (CoMPIA) is developed as a novel 3D-QSAR method by adding postulated pseudo receptor and GA-optimized probe into com- parative molecular field analysis (CoMFA). CoMPIA is used to find the pseudo receptor mode by opti- mizing probe distributions and to establish the opti- mal model of high qualities and good interpretations. Correlative coefficient R2, cross-validated correlative coefficient Q2 and root mean square error RMSEP of the resulting model are 0.940, 0.868 and 0.502, re- spectively by applying CoMPIA to quantitative struc- ture-activity relationship (QSAR) of 31 classical ster- oids. | ZHOU Peng TONG Jianbo TIAN Feifei LI Zhiliang | 2006 | Chinese Science Bulletin2006，51，15： | 5 |
| 20 | 3-49 Carbon Ions Induce Autophagy Effectively through Stimulating the Unfolded Protein Response and Subsequent Inhibiting Akt Phosphorylation in Tumor Cells显示文摘Because ER stress is one of the signaling pathways involved in the regulation of autophagy, we hypothesized that ER stress might also play an important role in radiation-induced autophagy. SHG44 and HeLa cells were irradiated with X-rays and carbon ions of 30 and 75 keV/m at 2 Gy. The expression levels of Bip, a major indicator of UPR, at 4 and 24 h post-irradiation are shown in Fig. 1(a) and (b) for SHG44 and HeLa cells, respectively. | Jin Xiaodong Li Feifei Li Qiang | 2015 | IMP & HIRFL Annual Report2015，，1： | 5 |
