| 1 | New In-Situ LA-ICP-MS U-Pb Ages of Uraninite from the Mianhuakeng Uranium Deposit, Northern Guangdong Province, China: Constraint on the Metallogenic Mechanism显示文摘Objective Hydrothermal uranium deposits in South China have become one of the main uranium producers over the past several decades.Numerous uranium deposits are densely distributed in the Guidong and Zhuguangshan plutons of the Nanling region,which constitute the largest uranium mineralization area in China(Cai Yuqi et al.,2015).The Mianhuakeng(MHK)uranium deposit,one of the | ZHONG Fujun PAN Jiayong QI Jiaming YAN Jie LIU Wenquan LI Haidong | 2018 | Acta Geologica Sinica(English Edition)2018，92，2： | 14 |
| 2 | Effect of dry density on ^(125)I diffusion in GMZ bentonite显示文摘Gaomiaozi(GMZ) bentonite is regarded as the favorable candidate backfilling material for a potential repository in China.It is important to understand the diffusion behavior of 125 I in GMZ bentonite and compare the diffusion behavior in GMZ and other types of bentonite like MX-80,Avonlea,etc.Therefore,through-and out-diffusion experiments were conducted to obtain the effective diffusion coefficient(D e) and distribution coefficient(K d).A computer code named Fitting for diffusion coefficient(FDP) was used for the experimental data processing and theoretical modeling.At the dry density of GMZ bentonite from 1600-2000 kg/m 3,the D e values of 125 I were(2.4-20.4) × 10-12 m 2 /s and K d values were constants.At dry density above 1800 kg/m 3,the diffusion behaviors were almost the same,indicating that the anion exclusion was ineffective.Out-diffusion results showed that the species of 125 I may be changed during the diffusion processing.It was probably caused by some organic matters or reducing substances in GMZ bentonite.Since the main composition of bentonite is montmorillonite,similar diffusion parameters were obtained in GMZ and other types of bentonite.The relationship of D e and accessible porosity(acc) could be described by Archie's law with exponent n = 1.2-2.8 for 125 I diffusion in bentonite,whereas n = 2.0 in GMZ bentonite.Furthermore,bentonite with the dry density of 1800 kg/m 3 was proposed as the backfilling materials used in the construction of high level radioactivity waste repository. | WU Tao LI JinYing DAI Wei XIAO GuoPing SHU FuJun YAO Jun SU YuLan SHI Lei | 2012 | Science China Chemistry2012，55，9： | 11 |
| 3 | DNA barcoding of 18 species of Bovidae显示文摘Genetic divergences of mitochondrial cytochrome c oxidase subunit I genes,known as DNA barcodes,have been used in species identification in the animal kingdom.Barcodes can assist field workers and taxonomists to determine groups in need of taxa analysis,and facilitate the recognition of appropriate populations and scales for conservation planning.In this study,18 species of Bovidae were selected to evaluate the effectiveness of DNA barcoding for species differentiation.The results showed that all but 2 species had unique DNA barcodes.The mean intraspecific variation was 0.63%,yielding a threshold of 6.3% for flagging putative species.The results supported the inference that barcode variation within species of mammals is somewhat higher than within other animal groups.The present study validated the effectiveness of barcoding for the identification of bovid species. | CAI YanSen ZHANG Liang SHEN FuJun ZHANG WenPing HOU Rong YUE BiSong LI Jing ZHANG ZhiHe | 2011 | Chinese Science Bulletin2011，56，2： | 10 |
| 4 | LncRNA Nron regulates osteoclastogenesis during orthodontic bone resorption显示文摘Activation of osteoclasts during orthodontic tooth treatment is a prerequisite for alveolar bone resorption and tooth movement.However,the key regulatory molecules involved in osteoclastogenesis during this process remain unclear.Long noncoding RNAs(lnc RNAs)are a newly identified class of functional RNAs that regulate cellular processes,such as gene expression and translation regulation.Recently,lnc RNAs have been reported to be involved in osteogenesis and bone formation.However,as the most abundant noncoding RNAs in vivo,the potential regulatory role of lnc RNAs in osteoclast formation and bone resorption urgently needs to be clarified.We recently found that the lnc RNA Nron(long noncoding RNA repressor of the nuclear factor of activated T cells)is highly expressed in osteoclast precursors.Nron is downregulated during osteoclastogenesis and bone ageing.To further determine whether Nron regulates osteoclast activity during orthodontic treatment,osteoclastic Nron transgenic(Nron c TG)and osteoclastic knockout(Nron CKO)mouse models were generated.When Nron was overexpressed,the orthodontic tooth movement rate was reduced.In addition,the number of osteoclasts decreased,and the activity of osteoclasts was inhibited.Mechanistically,Nron controlled the maturation of osteoclasts by regulating NFATc1 nuclear translocation.In contrast,by deleting Nron specifically in osteoclasts,tooth movement speed increased in Nron CKO mice.These results indicate that lnc RNAs could be potential targets to regulate osteoclastogenesis and orthodontic tooth movement speed in the clinic in the future. | Ruilin Zhang Junhui Li Gongchen Li Fujun Jin Zuolin Wang Rui Yue Yibin Wang Xiaogang Wang Yao Sun | 2020 | International Journal of Oral Science2020，12，2： | 9 |
| 5 | Mechanical properties of rock under coupled static-dynamic loads显示文摘Rock drilling machine,INSTRON testing system,and SHPB device are updated to investigate the characteristics of rocks at great depth,with high loads from overburden,tectonic stresses and dynamic impacts due to blasting and boring.It is verified that these testing systems can be used to study the mechanical properties of rock material under coupled static and dynamic loading condition and give useful guidance for the deep mining and underground cavern excavation.Various tests to determine the rock strength,fragmentation behavior,and energy absorption were conducted using the updated testing systems.It is shown that under coupled static-dynamic loads,if the axial prestress is lower than its elastic limit,the rock strength is higher than the individual static or dynamic strength.At the same axial prestress,rock strength under coupled loads rises with the increasing strain rates.Under coupled static and dynamic loads,rock is observed to fail with tensile mode.While shear failure may exist if axial prestress is high enough.In addition,it is shown that the percentage of small particles increases with the increasing axial prestress and impact load based on the analysis of the particle-size distribution of fragments.It is also suggested that the energy absorption ratio of a specimen varies with coupled loads,and the maximum energy absorption ratio for a rock can be obtained with an appropriate combination of static and dynamic loads. | Xibing Li Zilong Zhou Fujun Zhao Yujun Zuo Chunde Ma Zhouyuan Ye Liang Hong | 2009 | Journal of Rock Mechanics and Geotechnical Engineering2009，1，1： | 8 |

| 7 | Variations in leaf characteristics of three species of angiosperms with changing of altitude in Qilian Mountains and their inland high-altitude pattern显示文摘In this study,39 leaf samples of three angiosperms(Betula albo-sinensis,tree species;and Caragana jubata and Berberis diaphana,shrub species) were collected in the middle-east parts at 2300–3640 m asl of the Qilian Mountains to study the variations of leaf characteristics of angiosperms with altitude change in inland high-altitude regions of China.Five leaf indexes,viz.epidermal cell density(ED),stomatal density(SD),stomatal index(SI),leaf vein density(VD) and carbon isotopic ratio(δ13C),were analyzed in laboratory.The results show that there are significant or even very significant linear correlations between the five indexes and altitude,of which SD,SI and VD exhibit a negative correlation with altitude,while ED and δ13C exhibit a positive correlation with altitude.Such a correlation assemblage is quite different from the situation in the low-altitude humid environment.Generally,only an assemblage of positive correlations can be observed between the indexes(viz.SD,SI and δ13C,etc.) and the altitude in the low-altitude humid environment,which were caused mainly by the plants' responses to the change of atmospheric CO2 concentration(Cα).However,an assemblage of the negative and positive correlations found here may be attributed mainly to the plants' responses to the change of physiological drought caused by change of low temperature,and here it is preliminarily called the inland high-altitude pattern of plant leaf variations. | WANG XueFang LI RuiYun LI XiaoZe MA FuJun SUN BaiNian WU JingYu WANG YouKui | 2014 | Science China Earth Sciences2014，57，4： | 8 |
| 8 | Bamboo Leaf and Pollen Fossils from the Late Miocene of Eastern Zhejiang,China and their Phytogeological Significance显示文摘Fossil bamboo leaves and pollen from Upper Miocene deposits of the Shengxian Formation in Tiantai and Ninghai counties,eastern Zhejiang,China represent a rare record in Asia.The distinctive pseudopetiole and parallel venation of the leaf blades and the clearly thickened annulus of the pollen aperture place them in the subfamily Bambusoideae.Morphological analysis supports the determination of these fossil leaves as belonging to the genus Bambusium and two new species are described.Bambusium latipseudopetiolus Q.J.Wang et B.N.Sun sp.nov.has a distinctly wide pseudopetiole of 0.23 cm in width and 0.40 cm in length,several vascular bundles on parallel veins,and 5–8 lateral veins on both sides of the midrib.Bambusium longipseudopetiolus Q.J.Wang et B.N.Sun sp.nov.has a distinctly long pseudopetiole of 0.60 cm in length and 0.10 cm in width,several vascular bundles on the pseudopetiole,and 6 lateral veins on both sides of the midrib.Pollen grains from the same layer provide additional evidence of bamboos.They are characterized by 32.0–51.0 μm in diameter,a round pore 3.0–4.0 μm in diameter with a broad thickened annulus 2.5–3.5 μm around,and several conspicuous secondary folds on the exine surface.The morphological analysis leads to their assignment to Graminidites bambusoides Stuchlik.These fossils are important for the study of bamboo phytogeography in China.They demonstrate that there were bamboos growing in southeastern China during the Late Miocene and that bamboos in Zhejiang begin to diversify no later than the Late Miocene.In combination with bamboo fossils from other places,it seems that bamboos had a wide distribution across southern China during the Miocene,ranging from southwestern Yun'nan to southeastern Zhejiang. | WANG Qiujun MA Fujun YANG Yi DONG Junling WANG Haofei LI Ruiyun XU Xiaohui SUN Bainian | 2014 | Acta Geologica Sinica(English Edition)2014，88，4： | 7 |
| 9 | A general alternate loading technique and its applications in the inverse designs of centrifugal and mixed-flow pump impellers显示文摘For the inverse designs of centrifugal and mixed-flow pump impellers,clarifying the generation process of secondary flows and putting forward corresponding suppression measures is an important approach to improve the impeller performance.In this paper,to provide a better qualitative insight into the generation mechanism of secondary flows in the impeller,a simple kinematic equation is derived based on the ideal assumptions,which indicates that the potential rothalpy gradient(PRG)is the most important dynamic source that actively induces secondary vortical flows.Induced by the natural adverse PRG on the S1 and S2 stream surfaces,two typical secondary flows,H-S and P-S secondary flows,are clearly presented.To specially suppress these typical secondary flows,a general alternate loading technique(GALT)is proposed,aiming to adjust the real blade loadingδp to control the PRG features.At the blade fore part,theδp on the hub streamline should be slowly increased to avoid breakneck growth of the potential rothalpy to reduce adverse streamwise PRG on the S2 streamsurface.At the blade middle part,theδp should be moderately decreased to reduce adverse streamwise PRG on the S1 streamsurface.At the blade aft part,the difference in theδp between the shroud and hub streamlines should be decreased faster to control the exit uniformity.By applying the GALT to the impeller designs of three typical pump types in hydraulic engineering,the organizational effect of the PRG on fundamental flow structures is proven.The GALT can effectively control the PRG distributions and suppress the secondary flows,thereby widening the pump’s high-efficiency zone,improving flow uniformity and suppressing pressure fluctuations.Compared with the current Z-G method and the ALT,the GALT can meet the requirements of'de-experience'better,thereby enabling the designers to obtain good products explicitly and quickly. | WANG ChaoYue WANG FuJun AN DongSen YAO ZhiFeng XIAO RuoFu LU Li HE ChengLian ZOU ZhiChao | 2021 | Science China(Technological Sciences)2021，64，4： | 7 |

| 11 | Mobile bed thickness in skewed asymmetric oscillatory sheet flows显示文摘A new instantaneous mobile bed thickness model is presented for sediment transport in skewed asymmetric oscillatory sheet flows. The proposed model includes a basic bed load part and a suspended load part related to the Shields parameter, and takes into account the effects of mass conservation, phase-lag, and asymmetric boundary layer development, which are important in skewed asymmetric flows but usually absent in classical models. The proposed model is validated by erosion depth and sheet flow layer thickness data in both steady and unsteady flows, and applied to a new instantaneous sediment transport rate formula. With higher accuracy than classical empirical models in steady flows, the new formula can also be used for instantaneous sediment transport rate prediction in skewed asymmetric oscillatory sheet flows. | Xin Chen Yong Li Fujun Wang | 2018 | Acta Mechanica Sinica2018，34，2： | 5 |
| 12 | Analysis of characteristics and predictive factors of immune checkpoint inhibitor-related adverse events显示文摘Objective:We aimed to retrospectively analyze the toxicity profiles and predictors of immune-related adverse events(irAEs)as well as the correlation between irAEs and the clinical efficacy of multi-type immune checkpoint inhibitors(ICIs)in patients with advanced pan-cancer in a real-world setting.Methods:We retrospectively analyzed data from 105 patients with advanced pan-cancer treated with multi-type ICIs at the First Hospital of Jilin University between January 1,2016 and August 1,2020.We used logistic regression analyses to investigate the associations of irAEs with clinical baseline characteristics,blood count parameters,and biochemical indicators during treatment.Receiver operating characteristic curves were used to determine cutoff values for parameters and area under the curve values.Kaplan–Meier and Cox multivariate regression analyses were performed to estimate the relationships of baseline characteristics and irAEs with progression-free survival(PFS)and overall survival(OS).Results:A lower relative lymphocyte count(cutoff=28.5%),higher albumin level(cutoff=39.05 g/L),and higher absolute eosinophil count(AEC)(cutoff=0.175×10^(9)/L)were significantly associated with the occurrence of irAEs,among which a higher AEC(cutoff=0.205×10^(9)/L)was strongly associated with skin-related irAEs[odds ratios(ORs)=0.163,P=0.004].Moreover,a higher lactate dehydrogenase level(cutoff=237.5 U/L)was an independent predictor of irAEs of grade≥3(OR=0.083,P=0.023).In immune cell subgroup analysis,a lower absolute count of CD8+CD28−suppressor T cells(OR=0.806;95%confidence interval:0.643–1.011;P=0.062),which are regulatory T lymphocytes,was associated with the occurrence of irAEs,although the difference was not statistically significant.Furthermore,a higher percentage of CD19+B cells was associated with the occurrence of irAEs of grade≥3(P=0.02)and grade≥2(P=0.051).In addition,patients with any grade of irAE had a significantly high PFS(8.37 vs.3.77 months,hazard ratios(HR)=2.02,P=0.0038)and OS(24.77 vs.13.83 months,HR=1.84;P=0.024).Conclusions:This retrospective study reports clinical profile data for irAEs in unselected patients in a real-world setting and explored some parameters that may be potential predictive markers of the occurrence,type,or grade of irAEs in clinical practice.Evidence of a correlation between safety and efficacy may facilitate a complete assessment of the risk-benefit ratio for patients treated with ICIs. | Rilan Bai Naifei Chen Xiao Chen Lingyu Li Wei Song Wei Li Yuguang Zhao Yongfei Zhang Fujun Han Zheng Lyu Jiuwei Cui | 2021 | Cancer Biology & Medicine2021，18，4： | 4 |

| 14 | A high-energy-density sodium-ion full battery based on tin anode显示文摘Sodium-ion batteries(SIBs) have been considered as promising candidates for large-scale energy storage, owing to the high abundance and low cost of sodium(Na) resources. However, the development of full SIB has been hindered by low energy density because of the sluggish kinetics of large Na^+. Here, we report a full SIB with commercial tin(Sn) anode, cross-linked Na_3V_2(PO_4)_3/carbon nanotubes composites(NVP-CNT) cathode, and ether-based electrolyte. Sn is capable of delivering high reversible capacity via formation of Na15 Sn4 and stable solid-electrolyte interface(SEI) in initial cycles. Meanwhile, the NASICON-type NVP enables ultrafast and stable Na^+intercalation/extraction, and the incorporation of CNT can improve its electrical conductivity. The assembled full SIB delivers high output voltage of ~3.2 V, high energy density of 253.4 W h kg^(-1) at1600 W kg^(-1) based on total mass of both cathode and anode, and remarkable capacity retention of 96.1% after 180 cycles. These merit construction of high-energy full SIBs and will promote the development of SIBs. | Mingming Song Chenchen Wang Dongfeng Du Fujun Li Jun Chen | 2019 | Science China Chemistry2019，62，5： | 3 |
| 15 | Review on the Progress of AlGaN-based Ultraviolet Light-Emitting Diodes显示文摘AlGaN-based materials have exhibited considerable potential for fabricating ultraviolet(UV)light-emitting diodes(LEDs)owing to their direct,wide,and adjustable energy bandgap.AlGaN-based devices have extensive appli-cability owing to their stable physico-chemical properties.With decades of research effort,significant progress has been achieved in enhancing the working efficiency of AlGaN-based LEDs by optimizing the crystalline qual-ity,doping efficiency,and device design.In this review,methods to obtain high-quality AlGaN-based materials,achieve high doping efficiency,and design UV-LED structures are summarized and discussed.Finally,the issues that need to be addressed in AlGaN-based UV-LED devices are highlighted. | Yuxuan Chen Jianwei Ben Fujun Xu Jinchai Li Yang Chen Xiaojuan Sun Dabing Li | 2021 | Fundamental Research2021，1，6： | 3 |

| 17 | Approaching 18%efficiency of ternary organic photovoltaics with wide bandgap polymer donor and well compatible Y6:Y6-1O as acceptor显示文摘A series of ternary organic photovoltaics(OPVs)are fabricated with one wide bandgap polymer D18-Cl as donor,and well compatible Y6 and Y6-1O as acceptor.The open-circuit-voltage(V_(OC))of ternary OPVs is monotonously increased along with the incorporation of Y6-1O,indicating that the alloy state should be formed between Y6 and Y6-1O due to their excellent compatibility.The energy loss can be minimized by incorporating Y6-1 O,leading to the V_(OC)improvement of ternary OPVs.By finely adjusting the Y6-1O content,a power conversion efficiency of 17.91%is achieved in the optimal ternary OPVs with 30 wt%Y6-1O in acceptors,resulting from synchronously improved short-circuit-current density(JSC)of 25.87 mA cm^(-2),fill factor(FF)of 76.92%and V_(OC)of 0.900 V in comparison with those of D18-Cl:Y6 binary OPVs.The JSC and FF improvement of ternary OPVs should be ascribed to comprehensively optimal photon harvesting,exciton dissociation and charge transport in ternary active layers.The more efficient charge separation and transport process in ternary active layers can be confirmed by the magnetophotocurrent and impedance spectroscopy experimental results,respectively.This work provides new insight into constructing highly efficient ternary OPVs with well compatible Y6 and its derivative as acceptor. | Xiaoling Ma Anping Zeng Jinhua Gao Zhenghao Hu Chunyu Xu Jae Hoon Son Sang Young Jeong Caixia Zhang Mengyang Li Kai Wang He Yan Zaifei Ma Yongsheng Wang Han Young Woo Fujun Zhang | 2021 | National Science Review2021，8，8： | 3 |

| 19 | Preharvest application of 1-methylcyclopropene and Ethephon altered cuticular wax biosynthesis and fruit quality of apples at harvest and during cold storage显示文摘To investigate the roles of Harvista(a sprayable 1-methylcyclopropene,1-MCP,available component is 150 g·hm^(-2))and Ethephon(1 mL·L^(-1))applied at preharvest in apple(Malus domestica Borkh.'Golden Delicious')fruit cuticular wax biosynthesis,the expression of genes related to fruit cuticular wax biosynthesis and ethylene biosynthesis and signaling,ethylene production rate,respiration rate,wax constituents and structure,and fruit quality were determined at harvest and during cold storage.The results showed that 1-MCP inhibited the expression levels of ethylene biosynthesis and signaling-related genes,decreased fruit ethylene production,and inhibited the expression of Md LACS1,Md CER6,Md CER4 and Md WSD1,which resulted in decreases in alcohols,acids,and esters content in fruit cuticular wax.1-MCP also reduced fruit dropping rate from 17.17%to 12%;maintained fruit firmness,soluble solids,titratable acidity during cold storage;showed about as one fifth in the total length and one third in the widest width of wax crack as that in control at harvest.In contrast,Ethephon produced the opposite effects.In conclusion,1-MCP inhibited fruit ethylene biosynthesis and signaling,and influenced fruit cuticular wax biosynthesis.Thus,the fruit cuticular wax constituents and structure was altered,and the fruit quality were maintained at harvest and during cold storage.The results provide a new technology for improving apple fruit harvest and postharvest quality by preharvest application of sprayable 1-MCP. | Fujun Li Xinyue Zhang Jihan Wang Yaping Jiang Xinhua Zhang Xiaoan Li | 2022 | Horticultural Plant Journal2022，8，2： | 2 |
| 20 | Fossil Liverworts from the Lower Cretaceous Huolinhe Formation in Inner Mongolia, China显示文摘A new genus and species, Rebouliothallus huolinhensis sp. nov., and two uncertain species, Ricciopsis sp. and Hepaticites sp., are described. The fossils were collected from the Lower Cretaceous Huolinhe Formation of Huolinhe Basin, northeastern China. The new genus Rebouliothallus was established in the Aytoniaceae family of Marchantiales. Rebouliothallus huolinhensis appears to be quite similar to species of the extant genus Reboulia Raddi. The species is characterized by the relatively large ventral scales. Ventral scales are large, imbricate and arranged in two rows on the ventral surface. Rhizoids are either pegged or smooth. Ricciopsis sp. is characterized by the rosetteforming thallus. Hepaticites sp. shows some similarities to liverworts. Of the forty-nine Early Cretaceous floras of China, only two floras, one from the Huolinhe basin, Inner Mongolia and the other from the Jixi Basin, Heilongjiang Province, contain fossil liverworts. The rare fossil liverwort records in the Early Cretaceous floras of China may be the result of taphonomic bias. | LI Ruiyun WANG Xuelian JIN Peihong MA Fujun YAN Defei LIN Zhicheng SUN Bainian | 2016 | Acta Geologica Sinica(English Edition)2016，90，3： | 2 |
