| 1 | The growth mechanism of the basic magnesium chloride whisker显示文摘Based on the theoretical model of anion coordination polyhedron growth units, the growth mechanism of the basic magnesium chloride whisker was discussed in this paper.It was found that the basic magnesium chloride whisker habits were related to the different environments in which anion coordination polyhedra grew. The growth units of basic magnesium chloride whiskers are [Mg - (OH) 4]2 -and [Mg - Cl 4]2 -. The growth process is the incorporation process of growth units. Growth units will have different incorporations and orientations caused by different system characters or heating. Furthermore, the formation mechanism of basic magnesium chloride whiskers was also interpreted using anion coordination polyhedron growth units. | WU JianSong XIAO YingKai SU JingYun DENG TingTing FENG JieRong MO YuYing ZENG Mei | 2011 | Science China(Technological Sciences)2011，54，3： | 18 |
| 2 | The growth mechanism of hydrotalcite crystal显示文摘From the point of growth units, the growth mechanism of hydrotalcite (HT) crystal is investigated in this paper. Results show that the growth morphology of HT is consistent with the model of anion coordination polyhedron growth units. The Raman shift of growth solutions of HT, Cu-HTlc, and Cu-Zn-HTlc are monitored using Raman spectroscopy. In the experiment, the growth units of Mg-Al-hydrotalcite are [Mg-(OH)6]4- and [Al-(OH)6]3-, and the growth units of Cu-Htlc and Cu-Zn-HTlc are [Mg-(OH)6]4- and [Al-(OH)6]3-, respectively. The growth process of hydrotalcite is as follows: growth units first incorpo- rate into metal layers, then metal layers adsorb An- and H2O, and the growth units incorporate into layer compounds according to this rule. Growth units will have different incorporations and growth morphologies caused by different growth surroundings. Furthermore, the reason why Cu-HTlc is difficult to synthesize is also interpreted in this paper. | WU JianSong XIAO YingKai WAN JianYu WEN LiRong | 2012 | Science China(Technological Sciences)2012，55，4： | 15 |
| 3 | Inhibition of acetylcholinesterase by two genistein derivatives:kinetic analysis,molecular docking and molecular dynamics simulation显示文摘In this study two genistein derivatives(G1 and G2)are reported as inhibitors of acetylcholinesterase(AChE)and butyrylcholinesterase(BuChE),and differences in the inhibition of AChE are described.Although they differ in structure by a single methyl group,the inhibitory effect of G1(IC50¼264 nmol/L)on AChE was 80 times stronger than that of G2(IC50¼21,210 nmol/L).Enzyme-kinetic analysis,molecular docking and molecular dynamics(MD)simulations were conducted to better understand the molecular basis for this difference.The results obtained by kinetic analysis demonstrated that G1 can interact with both the catalytic active site and peripheral anionic site of AChE.The predicted binding free energies of two complexes calculated by the molecular mechanics/generalized born surface area(MM/GBSA)method were consistent with the experimental data.The analysis of the individual energy terms suggested that a difference between the net electrostatic contributions(ΔEele+ΔGGB)was responsible for the binding affinities of these two inhibitors.Additionally,analysis of the molecular mechanics and MM/GBSA free energy decomposition revealed that the difference between G1 and G2 originated from interactions with Tyr124,Glu292,Val294 and Phe338 of AChE.In conclusion,the results reveal significant differences at the molecular level in the mechanism of inhibition of AChE by these structurally related compounds. | Jiansong Fang Ping Wu Ranyao Yang Li Gao Chao Li Dongmei Wang Song Wu Ai-Lin Liu Guan-Hua Du | 2014 | Acta Pharmaceutica Sinica B2014，4，6： | 5 |
| 4 | Sex disparity of lung cancer risk in non-smokers:a multicenter population-based prospective study based on China National Lung Cancer Screening Program显示文摘Background: Non-smokers account for a large proportion of lung cancer patients, especially in Asia, but the attention paid to them is limited compared with smokers. In non-smokers, males display a risk for lung cancer incidence distinct from the females-even after excluding the influence of smoking;but the knowledge regarding the factors causing the difference is sparse. Based on a large multicenter prospective cancer screening cohort in China, we aimed to elucidate the interpretable sex differences caused by known factors and provide clues for primary and secondary prevention.Methods: Risk factors including demographic characteristics, lifestyle factors, family history of cancer, and baseline comorbidity were obtained from 796,283 Chinese non-smoking participants by the baseline risk assessment completed in 2013 to 2018. Cox regression analysis was performed to assess the sex difference in the risk of lung cancer, and the hazard ratios (HRs) that were adjusted for different known factors were calculated and compared to determine the proportion of excess risk and to explain the existing risk factors.Results: With a median follow-up of 4.80 years, 3351 subjects who were diagnosed with lung cancer were selected in the analysis. The lung cancer risk of males was significantly higher than that of females;the HRs in all male non-smokers were 1.29 (95% confidence interval [CI]: 1.20-1.38) after adjusting for the age and 1.38 (95% CI: 1.28-1.50) after adjusting for all factors, which suggested that known factors could not explain the sex difference in the risk of lung cancer in non-smokers. Known factors were 7% (|1.29-1.38|/1.29) more harmful in women than in men. For adenocarcinoma, women showed excess risk higher than men, contrary to squamous cell carcinoma;after adjusting for all factors, 47% ([1.30-1.16]/[1.30-1]) and 4% ([7.02-6.75]/[7.02-1])) of the excess risk was explainable in adenocarcinoma and squamous cell carcinoma. The main causes of gender differences in lung cancer risk were lifestyle factors, baseline comorbidity, and family history.Conclusions: Significant gender differences in the risk of lung cancer were discovered in China non-smokers. Existing risk factors did not explain the excess lung cancer risk of all non-smoking men, and the internal causes for the excess risk still need to be explored;most known risk factors were more harmful to non-smoking women;further exploring the causes of the sex difference would help to improve the prevention and screening programs and protect the non-smoking males from lung cancers. | Zheng Wu Fengwei Tan Zhuoyu Yang Fei Wang Wei Cao Chao Qin Xuesi Dong Yadi Zheng Zilin Luo Liang Zhao Yiwen Yu Yongjie Xu Jiansong Ren Jufang Shi Hongda Chen Jiang Li Wei Tang Sipeng Shen Ning Wu Wanqing Chen Ni Li Jie He | 2022 | Chinese Medical Journal2022，，11： | 3 |

| 6 | Macroporous composite capacitive bioanode applied in microbial fuel cells显示文摘Interfacial electron transfer between electroactive biofilm and the electrode was crucial step for microbial fuel cells(MFCs).A three-dimensional multilayer porous sponge coating with nitrogen-doped carbon nanotube/polyaniline/manganese dioxide(S/N-CNT/PANI/MnO2)electrode has been developed for MFC anode.Here,the S/N-CNT/PANI/MnO2 anode can function as a biocapacitor,able to store electrons generated from the degradation of organic substrate under the open circuit state and release the accumulated electrons upon requirement.Thus,the mismatching of the production and demand of the electricity can be overcome.Comparing with the sponge/nitrogen-doped carbon nanotube(S/N-CNT)bioanode,S/N-CNT/PANI/MnO2 capacitive bioanode displays a strong interaction with the microbial biofilm,advancing the electron transfer from exoelectrogens to the bioanode.The maximum power density of MFC with S/N-CNT/PANI/MnO2 capacitive bioanode is 1019.5 mW/m^2,which is 2.2 and5.8 times as much as that of S/N-CNT/MnO2 bioanode and S/N-CNT bioanode(470.7 mW/m^2 and176.6 mW/m^2),respectively.During the chronoamperometric experiment with 60 min of charging and 20 min of discharging,the S/N-CNT/PANI/MnO2 capacitive bioanode was able to store 10743.9 C/m^2,whereas the S/N-CNT anode was only able to store 3323.4 C/m^2.With a capacitive bioanode,it is possible to use the MFC simultaneously for production and storage of electricity. | Yuyang Wang Hongtao Zheng Ye Chen Qing Wen Jiansong Wu | 2020 | Chinese Chemical Letters2020，31，1： | 1 |
| 7 | Quantitative analysis of school safety events in China显示文摘Recent years have seen increasing school safety events along with growing numbers of students in China.In this paper,more than 400 serious school safety events between 2000 and 2018 in China were collected.The causes and characteristics of these events,taking into account the occurrence years,months,regions,education stages and types,were investigated.The results indicate that the number of school safety events has generally increased annually from 2000 to 2018 and can significantly vary each month,showing a higher frequency of occurrence during the“First Semester”(generally from September to December in China).Moreover,spatial distribution of school safety events is normally related to regional economic development;it was found that Guangdong,Jiangsu and Shandong is a first-level occurrence hotspots,followed by Zhejiang,Henan,Hebei and Sichuan,which are secondary occurrence hotspots.Furthermore,statistical analysis shows that the number of school safety events that occurred in kindergartens,primary schools and middle schools are approximately equal(around 1/3).Finally,it was found that the school safety events caused by“Accident”(such as school bus accidents,school fires,crowded stampedes and the collapses of school buildings)occupy a large proportion(57%). | Xiaofeng Hu Jiansong Wu Yiping Bai Yue Xin | 2020 | Journal of Safety Science and Resilience2020，1，2： | 1 |

| 9 | A high-resolution route map reveals distinct stages of chondrocyte dedifferentiation for cartilage regeneration显示文摘Articular cartilage damage is a universal health problem.Despite recent progress,chondrocyte dedifferentiation has severely compromised the clinical outcomes of cell-based cartilage regeneration.Loss-of-function changes are frequently observed in chondrocyte expansion and other pathological conditions,but the characteristics and intermediate molecular mechanisms remain unclear.In this study,we demonstrate a time-lapse atlas of chondrocyte dedifferentiation to provide molecular details and informative biomarkers associated with clinical chondrocyte evaluation.We performed various assays,such as single-cell RNA sequencing(scRNA-seq),live-cell metabolic assays,and assays for transposase-accessible chromatin with high-throughput sequencing(ATAC-seq),to develop a biphasic dedifferentiation model consisting of early and late dedifferentiation stages.Early-stage chondrocytes exhibited a glycolytic phenotype with increased expression of genes involved in metabolism and antioxidation,whereas late-stage chondrocytes exhibited ultrastructural changes involving mitochondrial damage and stress-associated chromatin remodeling.Using the chemical inhibitor BTB06584,we revealed that early and late dedifferentiated chondrocytes possessed distinct recovery potentials from functional phenotype loss.Notably,this two-stage transition was also validated in human chondrocytes.An image-based approach was established for clinical use to efficiently predict chondrocyte plasticity using stage-specific biomarkers.Overall,this study lays a foundation to improve the quality of chondrocytes in clinical use and provides deep insights into chondrocyte dedifferentiation. | Yishan Chen Yeke Yu Ya Wen Juan Chen Junxin Lin Zixuan Sheng Wenyan Zhou Heng Sun Chengrui An Jiansong Chen Weiliang Wu Chong Teng Wei Wei Hongwei Ouyang | 2022 | Bone Research2022，10，3： | 1 |

| 12 | Multifunctional Gd-CuS loaded UCST polymeric micelles for MR/PA imaging-guided chemo-photothermal tumor treatment显示文摘Hepatocellular carcinoma(HCC)is a life-threatening disease for which there is no effective treatment currently.Novel theranostics simultaneously having excellent imaging and therapeutic functions are highly desired in cancer therapy.Herein,we develop the sialic acid(SA)modified polymeric micelles at an upper critical solution temperature(UCST)of 43℃(sialic acid-poly(ethylene glycol)-poly(acrylamide-co-acrylonitrile),SA-PEG-p(AAm-co-AN)),which further encapsulated with doxorubicin(DOX)and Gd-CuS nanoparticles(Gd-CuS NPs)for chemo-photothermal treatment of HCC guided by magnetic resonance(MR)/photoacoustic(PA)dual-mode imaging.The resultant SA-PEG-p(AAm-co-AN)/DOX/Gd-CuS(SPDG)had an excellent photothermal conversion efficiency,enabling SPDG with an instantaneous release behavior of DOX under near-infrared(NIR)irradiation.This study also revealed that SPDG could actively target to HCC,which was due to that SA had a high affinity with E-selectin overexpressed at the tumor site.Moreover,benefiting from the HCC-targeted ability and NIR light-controlled on-demand delivery of DOX,SPDG showed a superior potential in MR/PA dual-mode imaging-guided chemo-photothermal treatment.Overall,our study reveals that the designed SPDG may be used as an ideal multifunctional nanoplatform for cancer theranostics. | Yan Du Di Liu Mingchen Sun Gaofeng Shu Jing Qi Yuchan You Yiting Xu Kai Fan Xiaoling Xu Feiyang Jin Jun Wang Qiying Shen Luwen Zhu Xiaoying Ying Jiansong Ji Liming Wu Daren Liu Yongzhong Du | 2022 | Nano Research2022，15，3： | 0 |

| 14 | The optimal power distribution in cooperative communication relay system显示文摘In order to optimize power utilization of relay nodes in cooperative communication,a power allocation algorithm with objective function to maximize system capacity is proposed.Based on the convex optimization theory,an ellipsoid algorithm is used to solve this problem,which could simplify the subgradient choosing steps and improve convergence stability,so that an optimized power allocation algorithm is presented.Theoretical analysis and simulation results show that the algorithm can effectively distribute the power of each node with lower complexity,and ensure the transmission capability of relay nodes in cooperative communication. | 张超一 Wu Muqing Miao Jiansong Luan Linlin | 2013 | High Technology Letters2013，19，4： | 0 |
| 15 | Potential risks of organic contaminated soil after persulfate remediation:Harmful gaseous sulfur release显示文摘Persulfate is considered a convenient and efficient remediation agent for organic contaminated soil.However,the potential risk of sulfur into the soil remediation by persulfate remains ignored.In this study,glass bottles with different persulfate dosages and groundwater tables were set up to simulate persulfate remediation of organic pollutants(aniline).The results found sulfate to be the main end-product(83.0%–99.5%)of persulfate remediation after10 days.Moreover,H_(2)S accounted for 93.4%–99.4%of sulfur reduction end-products,suggesting that H_(2)S was the final fate of sulfur.H_(2)S was released rapidly after one to three days at a maximum concentration of 33.0 ppm,which is sufficient to make a person uncomfortable.According to the fitted curve results,H_(2)S concentration decreased to a safe concentration(0.15 ppm)after 20–85 days.Meanwhile,the maximum concentration of methanethiol reached 0.6 ppm.These results indicated that secondary pollution from persulfate remediation could release harmful gases over a long time.Therefore,persulfate should be used more carefully as a remediation agent for soil contamination. | Yuyang Long Zixiao Wu Xiaodong Ding Jiansong Chen Dongsheng Shen Jiali Shentu Cai Hui | 2024 | Journal of Environmental Sciences2024，，1： | 0 |

| 17 | OsNRAMP2 facilitates Cd efflux from vacuoles and contributes to the difference in grain Cd accumulation between japonica and indica rice显示文摘Cadmium(Cd)accumulation in rice grain is of health concern.Identifying genes involved in grain Cd accumulation and performing molecular breeding may reduce it.In this study,knockout of OsNRAMP2,a member of the NRAMP family,reduced grain Cd concentrations by more than 38%,and overexpressing OsNRAMP2 increased grain Cd concentrations by more than 50%.Physiological experiments showed that OsNRAMP2 facilitated Cd translocation from root to shoot by positively regulating Cd efflux from the vacuoles.At filling stage,OsNRAMP2 was highly expressed in all tissues except for husk,suggesting its role in Cd remobilization.Changes in OsNRAMP2 expression affected the concentrations of Fe,Mn,Zn,and Cu in grain and also affected rice growth.Phylogenetic analysis showed that the distribution of OsNRAMP2 haplotypes between japonica and indica was different.Among the four haplotypes of OsNRAMP2,Hap 1,with a 6-bp nucleotide insertion in exon 1,had grain Cd concentration at least 45.3%lower than any of the other three haplotypes.Almost all(99.3%)japonica accessions but rare indica accessions(4.44%)from the 3K sequenced rice genomes carry Hap 1 of OsNRAMP2.Our study sheds light on the molecular mechanism of grain Cd accumulation and provides a promising target for low-Cd rice breeding. | Wu Yang Luo Chen Yamei Ma Rui Hu Jian Wang Wenhui Li Jingfang Dong Tifeng Yang Lian Zhou Jiansong Chen Dilin Liu Ning Yu Zhixia Liu Lingyan Zhou Shaohong Zhang Junliang Zhao Bin Liu | 2023 | The Crop Journal2023，11，2： | 0 |
| 18 | Coronaviruses RNA interacts with host miR-500a-5p and miR-501-5p to regulate multiple pathways显示文摘The Coronavirus disease is the contagious disease. Clinical manifests vary from no symptoms, upper and lower respiratory tract infections, and even severe acute respiratory distress syndrome and multiple organs failure. Recently, three of new beta-coronaviruses have emerged to cause serious and widespread illness and death, such as the Severe Acute Respiratory Syndrome Coronaviruses (SARS-CoV), Middle East Respiratory Syndrome Coronaviruses (MERS-CoV), and 2019-nCoV (the causative pathogen of Coronavirus Disease 2019 (COVID-19). The COVID-19 is continuing to spread globally. However, the detailed molecular mechanisms have not yet been fully clarified. Since the similarity of the pathological features among 2019-nCoV, SARS-CoV and MERS-CoV, we could speculate the biological features of current COVID-19 by researching those of MERS-CoV and SARS-CoV. Therefore, we analyzed expression levels of miRNA and mRNA profiles of MERS-CoV, SARS-CoV and 2019-nCoV from five public GEO datasets (Table S1). As a result, we found 16 miRNAs potentially target a group of hub genes clustering together to tune the immune response. Notably, viral RNAs have the ability to sponge miR-500a-5p and miR-501-5p, indicating viral RNAs sequestering these two miRNAs to trigger genes expression and contribute to pathogenesis. We hope this study will pave the way to better understand 2019-nCoV pathogenesis and develop the innovative therapeutics. | Qi Guo Linghui Tan Jiajia Pan Songfang Wu Jiansong Huang Fang Yu Jinghan Wang | 2023 | Genes & Diseases2023，10，2： | 0 |
| 19 | Civil gas energy accidents in China from 2012-2021显示文摘In this study,civil gas energy accidents reported by the China Gas Network and related organizations from 2012 to 2021 were collected,and a comprehensive multidimensional correlation analysis was conducted considering factors such as accident timing,geography,causes,and casualties.The results identified July and August,Mondays and Sundays,and the morning,mid-day,and evening cooking times as the high-incidence months,days,and times for gas accidents,respectively.Gas accidents were found to occur more frequently in eastern coastal areas,provincial capitals,and larger cities,while residential and construction sites were identified as high-risk areas for gas accidents.Explosions were the most prevalent type of gas accident,followed by leaks,fires,and poisoning.Third-party construction and valve issues were identified as the primary factors contributing to gas leakage,whereas cooking was identified as the most common ignition source.An analysis of the Pearson correlation coefficient indicated a significant correlation among the gas accident factors.Moreover,a time-series prediction model was developed to forecast gas accidents in China,with the results demonstrating fluctuating gas accidents.This study proposes targeted preventive measures in terms of publicity,education,equipment,and facilities to provide scientific support to government units to improve civil gas energy security measures. | Lei Pang Wei Li Kai Yang Lu Meng Jiansong Wu Jinglun Li Lishun Ma Sisi Chen Yan Liang | 2023 | Journal of Safety Science and Resilience2023，4，4： | 0 |
| 20 | An online monitor ionization chamber used in particle therapy显示文摘The clinical trials of tumor therapy using heavy ions beam 12C are now in progress at Institute of Modern Physics in Lanzhou. In order to achieve the precise radiotherapy with the high energy 12C beam in active pencil beam scanning mode, we have developed an ionization chamber(IC) as an online monitor for beam intensity and also a dosimeter after calibration. Through the choosing of working gas and voltage, optimizing of the electrics and the read-out system, calibrating the linearity, the detector system provide us one of the simple and highly reliable way to monitoring the beam during the active pencil beam scanning treatments. The measurement results of this detector system show that it could work well under the condition of high energy 12C beam in active pencil beam scanning mode. | TANG Bin HU Zhengguo MAO Ruishi XU Zhiguo WANG Jiansong YUE Ke TU Xiaolin WU Dapeng CHEN Jinda ZHANG Jie WANG Meng SUN Zhiyu ZHANG Xueheng LI Qiang XU Hushan XIOA Guoqing | 2009 | Nuclear Science and Techniques2009，20，3： | 0 |
