| 3 | The impact of climate change on forest fire danger rating in China’s boreal forest显示文摘The Great Xing'an Mountains boreal forests were focused on in the northeastern China.The simulated future climate scenarios of IPCC SRES A2a and B2a for both the baseline period of 1961-1990 and the future scenario periods were downscaled by the Delta Method and the Weather Generator to produce daily weather data.After the verification with local weather and fire data,the Canadian Forest Fire Weather Index System was used to assess the forest fire weather situation under climate change in the study region.An increasing trend of fire weather severity was found over the 21st century in the study region under the both future climate change scenarios,compared to the 1961-1990 baseline period.The annual mean/maximum fire weather index was predicted to rise continuously during 2010-2099,and by the end of the 21st century it is predicted to rise by 22%-52% across much of China's boreal forest.The significant increases were predicted in the spring from of April to June and in the summer from July to August.In the summer,the fire weather index was predicted to be higher than the current index by as much as 148% by the end of the 21st century.Under the scenarios of SRES A2a and B2a,both the chance of extremely high fire danger occurrence and the number of days of extremely high fire danger occurrence was predicted to increase in the study region.It is anticipated that the number of extremely high fire danger days would increase from 44 days in 1980s to 53-75 days by the end of the 21st century. | YANG Guang DI Xue-ying GUO Qing-xi SHU Zhan ZENG Tao YU Hong-zhou WANG Chao | 2011 | Journal of Forestry Research2011，22，2： | 12 |
| 4 | Fog Computing Dynamic Load Balancing Mechanism Based on Graph Repartitioning显示文摘Because of cloud computing's high degree of polymerization calculation mode, it can't give full play to the resources of the edge device such as computing, storage, etc. Fog computing can improve the resource utilization efficiency of the edge device, and solve the problem about service computing of the delay-sensitive applications. This paper researches on the framework of the fog computing, and adopts Cloud Atomization Technology to turn physical nodes in different levels into virtual machine nodes. On this basis, this paper uses the graph partitioning theory to build the fog computing's load balancing algorithm based on dynamic graph partitioning. The simulation results show that the framework of the fog computing after Cloud Atomization can build the system network flexibly, and dynamic load balancing mechanism can effectively configure system resources as well as reducing the consumption of node migration brought by system changes. | SONG Ningning GONG Chao AN Xingshuo ZHAN Qiang | 2016 | China Communications2016，13，3： | 8 |
| 5 | One Stone Four Birds:A Novel Liposomal Delivery System Multi-functionalized with Ginsenoside Rh2 for Tumor Targeting Therapy显示文摘Liposomes hold great potential in anti-cancer drug delivery and the targeting treatment of tumors.However,the clinical therapeutic efficacy of liposomes is still limited by the complexity of tumor microenvironment(TME)and the insufficient accumulation in tumor sites.Meanwhile,the application of cholesterol and polyethylene glycol(PEG),which are usually used to prolong the blood circulation and stabilize the structure of liposomes respectively,has been questioned due to various disadvantages.Herein,we developed a ginsenoside Rh2-based multifunctional liposome system(Rh2-lipo)to effectively address these challenges once for all.Different with the conventional’wooden’liposomes,Rh2-lipo is a much more brilliant carrier with multiple functions.In Rh2-lipo,both cholesterol and PEG were substituted by Rh2,which works as membrane stabilizer,long-circulating stealther,active targeting ligand,and chemotherapy adjuvant at the same time.Firstly,Rh2 could keep the stability of liposomes and avoid the shortcomings caused by cholesterol.Secondly,Rh2-lipo showed a specifically prolonged circulation behavior in the blood.Thirdly,the accumulation of the liposomes in the tumor was significantly enhanced by the interaction of glucose transporter of tumor cells with Rh2.Fourth,Rh2-lipo could remodel the structure and reverse the immunosuppressive environment in TME.When tested in a 4T1 breast carcinoma xenograft model,the paclitaxel-loaded Rh2-lipo realized high efficient tumor growth suppression.Therefore,Rh2-lipo not only innovatively challenges the position of cholesterol as a liposome component,but also provides another innovative potential system with multiple functions for anti-cancer drug delivery. | Chao Hong Jianming Liang Jiaxuan Xia Ying Zhu Yizhen Guo Anni Wang Chunyi Lu Hongwei Ren Chen Chen Shiyi Li Dan Wang Huaxing Zhan Jianxin Wang | 2020 | Nano-Micro Letters2020，12，10： | 8 |
| 6 | Urinary metabolomics analysis identifies key biomarkers of different stages of nonalcoholic fatty liver disease显示文摘AIM To identify a panel of biomarkers that can distinguish between non-alcoholic fatty liver disease(NAFLD) and non-alcoholic steatohepatitis(NASH), and explore molecular mechanism involved in the process of developing NASH from NAFLD.METHODS Biomarkers may differ during stages of NAFLD. Urine and blood were obtained from non-diabetic subjects with NAFLD and steatosis, with normal liver function(n = 33), from patients with NASH, with abnormal liver function(n = 45), and from healthy age and sex-matched controls(n = 30). Samples were subjected to metabolomic analysis to identify potential non-invasive biomarkers. Differences in urinary metabolic profiles were analyzed using liquid chromatography tandem mass spectrometry with principal component analysis and partial least squares-discriminate analysis.RESULTS Compared with NAFLD patients, patients with NASH had abnormal liver function and high serum lipid concentrations. Urinary metabonomics found differences in 31 metabolites between these two groups, including differences in nucleic acids and amino acids. Pathway analysis based on overlapping metabolites showed that pathways of energy and amino acid metabolism, as well as the pentose phosphate pathway, were closely associated with pathological processes in NAFLD and NASH.CONCLUSION These findings suggested that a panel of biomarkers could distinguish between NAFLD and NASH, and could help to determine the molecular mechanism involved in the process of developing NASH from NAFLD. Urinary biomarkers may be diagnostic in these patients and could be used to assess responses to therapeutic interventions. | Shu Dong Zong-Ying Zhan Hong-Yan Cao Chao Wu Yan-qin Bian Jian-Yuan Li Gen-Hong Cheng Ping Liu Ming-Yu Sun | 2017 | World Journal of Gastroenterology2017，23，15： | 7 |
| 7 | Keyhole Foraminotomy via a Percutaneous Posterior Full-endoscopic Approach for Cervical Radiculopathy:An Advanced Procedure and Clinical Study显示文摘Endoscopic cervical foraminotomy is increasingly used for cervical spondylotic radiculopathy(CSR),but there is great concern about radiation exposure because of the heavy dependence of this surgical method on fluoroscopy.The objective of this study was to introduce in detail an advanced surgical technique of keyhole foraminotomy via a percutaneous posterior full-endoscopic approach as a treatment for CSR and investigate its clinical outcomes.We retrospectively reviewed 33 consecutive patients with CSR who underwent keyhole foraminotomy via a percutaneous posterior full-endoscopic approach from October 2015 to April 2017.The patients’general characteristics,including operative time,blood loss,hospital stay,complications,and recurrence,were obtained.Clinical outcomes were evaluated using the visual analogue scale(VAS)for radicular pain,the neck disability index(NDI)for functional assessment,and the modified MacNab criteria for patient satisfaction.All operations were successfully performed(mean operation time,62 min),with no measurable blood loss or severe related complications.The mean follow-up was 25 months.The VAS and NDI scores were significantly improved as compared with those in the preoperative period(preoperative vs.final follow-up:7.6±1.6 vs.3.83±7.34 for VAS,P<0.01;69.5%±10.5%vs.17.54%±13.40%for NDI,P<0.01).Of the 33 patients,32(97.0%)had good-to-excellent global outcomes and all patients obtained symptomatic improvement.In conclusion,keyhole foraminotomy via a percutaneous posterior full-endoscopic approach is an efficient,safe,and feasible procedure for the treatment of CSR.Its simplified single-step blunt incision for localization appears to decrease radiation exposure risks. | Rong-jin LUO Yu SONG Zhi-wei LIAO Hui-peng YIN Sheng-feng ZHAN Sai-deng LU Chao CHEN Cao YANG | 2020 | Current Medical Science2020，40，6： | 7 |

| 10 | Remote Sensing Retrieval of Surface Suspended Sediment Concentration in the Yellow River Estuary显示文摘Accurate assessment of surface suspended sediment concentration(SSSC) in estuary is essential to address several important issues: erosion, water pollution, human health risks, etc. In this study, an empirical cubic retrieval model was developed for the retrieval of SSSC from Yellow River Estuary. Based on sediments and seawater collected from the Yellow River and southeastern Laizhou Bay, SSSC conditions were reproduced in the laboratory at increasing concentrations within a range common to field observations. Continuous spectrum measurements of the various SSSCs ranging from 1 to 5700 mg/l were carried out using an Ava Field-3 spectrometer. The results indicated the good correlation between water SSSC and spectral reflectance(Rrs) was obtained in the spectral range of 726–900 nm. At SSSC greater than 2700 mg/L, the 740–900 nm spectral range was less susceptible to the effects of spectral reflectance saturation and more suitable for retrieval of high sediment concentrations. The best correlations were obtained for the reflectance ratio of 820 nm to 490 nm. Informed by the correlation between Rrs and SSSC, a retrieval model was developed(R2 = 0.992). The novel cubic model, which used the ratio of a near-infrared(NIR) band(740–900 nm) to a visible band(400–600 nm) as factors, provided robust quantification of high SSSC water samples. Two high SSSC centers, with an order of 103 mg/l, were found in the inversion results around the abandoned Diaokou River mouth, the present Yellow River mouth to the abandoned Qingshuigou River mouth. There was little sediment exchange between the two high SSSC centers due to the directions of the residual currents and vertical mixing. | ZHAN Chao YU Junbao WANG Qing LI Yunzhao ZHOU Di XING Qinghui CHU Xiaojing | 2017 | Chinese Geographical Science2017，27，6： | 5 |
| 11 | Wave Attenuation Performance and the Influencing Factors of A Lower Arc-Plate Breakwater显示文摘Comprehensive experimental and numerical studies have been undertaken to investigate wave energy dissipation performance and main influencing factors of a lower arc-plate breakwater. The numerical model, which considers nonlinear interactions between waves and the arc-plate breakwater, has been constructed by using the velocity wave- generating method, the volume of fluid (VOF) method and the finite volume method. The results show that the relative width, relative height and relative submergence of the breakwater are three main influencing factors and have significant influence on wave energy dissipation of the lower arc-plate open breakwater. The transmission coefficient is found to decrease with the increasing relative width, and the minimum transmission coefficient is 0.15 when the relative width is 0.45. The reflection coefficient is found to vary slightly with the relative width, and the maximum reflection coefficient is 0.53 when the relative width is 0.45. The transmission and reflection coefficients are shown to increase with the relative wave height for approximately 85% of the experimental tests when the relative width is 0.19 0.45. The transmission coefficients at relative submergences of 0.04, 0.02 and 0 are clearly shown to be greater than those at relative submergences of 0.02 and 0.04, while the reflection coefficient exhibits the opposite relationship. After the wave interacts with the lower arc-plate breakwater, the wave energy is mainly converted into transmission, reflection and dissipation energies. The wave attenuation performance is clearly weakened for waves with greater heights and longer periods. | LI Xue-yan WANG Qing YOU Zai-jin GUO Wei-jun ZHANG Jun-bin ZHAN Chao ZHANG Zhi-chen WANG Li-xue LI Qin | 2020 | China Ocean Engineering2020，34，1： | 5 |
| 12 | Dependence of creep age formability on initial temper of an Al-Zn-Mg-Cu alloy显示文摘The initial temper of the material may directly affect the whole creep age forming(CAF)process. In terms of creep deformation and stress relaxation, using the constant-stress creep aging and constant-strain stress relaxation aging tests, the relationship between initial temper and CAF formability is investigated for an Al-Zn-Mg-Cu alloy at 165 °C for 18 h. Three tempers are selected as the initial tempers in CAF, viz., solution, retrogression and re-solution. The CAF formability of this alloy with initial temper of retrogression is the best, and the creep strain of the retrogression tempered specimen after creep aging of 18 h is about 1.21 and 1.34 times than that of the solution and the re-solution tempered specimens, respectively. The calculated stress exponents of this alloy with three initial tempers range from 7.3 to 9.5, indicating that the CAF of this alloy is mainly controlled by the dislocation creep. The various formability for three initial tempers are attributed to different inhibitions of the transgranular precipitates on the dislocation movement. For the retrogression temper, the initial fine and uniformly distributed precipitates are seriously coarsened after6 h of CAF, which minimally inhibit the dislocation movement. While, for the re-solution temper,the fine precipitates are re-precipitated in the matrix of the alloy, which observably hinder the dislocation movement and lead to the worst formability. | Lei Chao Yang He Li Heng Shi Nian Fu Jin Zhan Lihua | 2016 | Chinese Journal of Aeronautics2016，29，5： | 5 |
| 13 | Substantial transition to clean household energy mix in rural China显示文摘The household energy mix has significant impacts on human health and climate,as it contributes greatly to many health-and climate-relevant air pollutants.Compared to the well-established urban energy statistical system,the rural household energy statistical system is incomplete and is often associated with high biases.Via a nationwide investigation,this study revealed high contributions to energy supply from coal and biomass fuels in the rural household energy sector,while electricity comprised∼20%.Stacking(the use of multiple sources of energy)is significant,and the average number of energy types was 2.8 per household.Compared to 2012,the consumption of biomass and coals in 2017 decreased by 45%and 12%,respectively,while the gas consumption amount increased by 204%.Increased gas and decreased coal consumptions were mainly in cooking,while decreased biomass was in both cooking(41%)and heating(59%).The time-sharing fraction of electricity and gases(E&G)for daily cooking grew,reaching 69%in 2017,but for space heating,traditional solid fuels were still dominant,with the national average shared fraction of E&G being only 20%.The non-uniform spatial distribution and the non-linear increase in the fraction of E&G indicated challenges to achieving universal access to modern cooking energy by 2030,particularly in less-developed rural and mountainous areas.In some non-typical heating zones,the increased share of E&G for heating was significant and largely driven by income growth,but in typical heating zones,the time-sharing fraction was<5%and was not significantly increased,except in areas with policy intervention.The intervention policy not only led to dramatic increases in the clean energy fraction for heating but also accelerated the clean cooking transition.Higher income,higher education,younger age,less energy/stove stacking and smaller family size positively impacted the clean energy transition. | Guofeng Shen Rui Xiong Yanlin Tian Zhihan Luo Bahabaike Jiangtulu Wenjun Meng Wei Du Jing Meng Yuanchen Chen Bing Xue Bin Wang Yonghong Duan Jia Duo Fenggui Fan Lei Huang Tianzhen Ju Fenggui Liu Shunxin Li Xianli Liu Yungui Li Mu Wang Ying Nan Bo Pan Yanfang Pan Lizhi Wang Eddy Zeng Chao Zhan Yilin Chen Huizhong Shen Hefa Cheng Shu Tao | 2022 | National Science Review2022，9，7： | 4 |

| 15 | Changes of Serum Insulin-like Growth Factor-2 Response to Negative Symptom Improvements in Schizophrenia Patients Treated with Atypical Antipsychotics显示文摘Accumulating evidence suggests that a disruption of early brain development,in which insulin-like growth factor-2(IGF-2)has a crucial role,may underlie the pathophysiology of schizophrenia.Our previous study has shown that decreased serum IGF-2 was correlated with the severity of psychopathology in patients with schizophrenia.Here we conducted a prospective observation trial to investigate the effects of atypical antipsychotics on serum IGF-2 level and its relationship with clinical improvements in schizophrenia patients.Thirty-one schizophrenia patients with acute exacerbation and 30 healthy individuals were recruited in this study.Psychiatric symptoms were assessed using the Positive and Negative Syndrome Scale(PANSS)and serum IGF-2 levels were determined using ELISA.We found that schizophrenia patients with acute exacerbation had lower serum IGF-2 levels than control individuals at baseline(P<0.05).After 2 months of atypical antipsychotic treatment,a significant improvement in each PANSS subscore and total score was observed in patients(all P<0.01),and the serum IGF-2 levels of patients were significantly increased compared with those at baseline(203.13±64.62 vs.426.99±124.26 ng/mL;t=−5.044,P<0.001).Correlation analysis revealed that the changes of serum IGF-2 levels in patients were significantly correlated with the improvements of negative symptoms(r=−0.522,P=0.006).Collectively,our findings demonstrated changes of serum IGF-2 response to improvements of negative symptoms in schizophrenia patients treated with atypical antipsychotics,suggesting that serum IGF-2 might be a treatment biomarker for schizophrenia. | Xue-lin CHAO Shu-zhen JIANG Jian-wen XIONG Jin-qiong ZHAN Bo WEI Chun-nuan CHEN Yuan-jian YANG | 2020 | Current Medical Science2020，40，3： | 3 |
| 16 | Large-scale multiferroic complex oxide epitaxy with magnetically switched polarization enabled by solution processing显示文摘Complex oxides with tunable structures have many fascinating properties,though high-quality complex oxide epitaxy with precisely controlled composition is still out of reach.Here we have successfully developed solution-based single-crystalline epitaxy for multiferroic(1-x)BiTi(1-y)/2FeyMg(1-y)/2O3–(x)CaTiO3(BTFM–CTO)solid solution in large area,confirming its ferroelectricity at the atomic scale with strong spontaneous polarization.Careful compositional tuning leads to a bulk magnetization of 0.07±0.035μB/Fe at room temperature,enabling magnetically induced polarization switching exhibiting a large magnetoelectric coefficient of 2.7–3.0×10^-7 s/m.This work demonstrates the great potential of solution processing in large-scale complex oxide epitaxy and establishes novel room-temperature magnetoelectric coupling in epitaxial BTFM–CTO film,making it possible to explore a much wider space of composition,phase,and structure that can be easily scaled up for industrial applications. | Cong Liu Feng An Paria S.M.Gharavi Qinwen Lu Junkun Zha Chao Chen Liming Wang Xiaozhi Zhan Zedong Xu Yuan Zhang Ke Qu Junxiang Yao Yun Ou Zhiming Zhao Xiangli Zhong Dongwen Zhang Nagarajan Valanoor Lang Chen Tao Zhu Deyang Chen Xiaofang Zhai Peng Gao Tingting Jia Shuhong Xie Gaokuo Zhong Jiangyu Li | 2020 | National Science Review2020，7，1： | 2 |

| 18 | Cryo-EM structure of the inner ring from the Xenopus laevis nuclear pore complex显示文摘Nuclear pore complex(NPC)mediates nucleocytoplasmic shuttling.Here we present single-particle cryo-electron microscopy structure of the inner ring(IR)subunit from the Xenopus laevis NPC at an average resolution of 4.2Å.A homo-dimer of Nup205 resides at the center of the IR subunit,flanked by two molecules of Nup188.Four molecules of Nup93 each places an extended helix into the axial groove of Nup205 or Nup188,together constituting the central scaffold.The channel nucleoporin hetero-trimer of Nup62/58/54 is anchored on the central scaffold.Six Nup155 molecules interact with the central scaffold and together with the NDC1–ALADIN hetero-dimers anchor the IR subunit to the nuclear envelope and to outer rings.The scarce inter-subunit contacts may allow sufficient latitude in conformation and diameter of the IR.Our structure reveals the molecular basis for the IR subunit assembly of a vertebrate NPC. | Gaoxingyu Huang Xiechao Zhan Chao Zeng Ke Liang Xuechen Zhu Yanyu Zhao Pan Wang Qifan Wang Qiang Zhou Qinghua Tao Minhao Liu Jianlin Lei Chuangye Yan Yigong Shi | 2022 | Cell Research2022，32，5： | 1 |
