1Palaeogeomorphology and its control on the development of sequence stratigraphy and depositional systems of the Early Silurian in the Tarim Basin显示文摘The Silurian in the Tarim Basin was deposited on the basement deformed by the Caledonian tectonic movements at the end of the Late Ordovician. The development and distribution of sedimentary sequences of the Early Silurian have been clearly controlled by the palaeogeomorphology of the Late Ordovician. Based on unconformity characteristics and distribution of erosion, several zones can be differentiated including a high uplifted erosion zone, a transitional slope zone and a depression zone. The central and west Tabei Uplift zones show high angular unconformity and intense erosion. The Tarim Basin in the late Ordovician shows characteristics of higher in the west, lower in the east while higher in the south, lower in the north. The Early Silurian mainly developed transgressive and highstand systems tracts on the whole, while the lowstand systems tract only developed partly below the slope break. The palaeogeomorphology controlled the clastic source supply and deposit distribution. Braided delta system and tidal flat–estuary system were deposited. The duration of uplifting of the Tazhong paleouplift was longer than that of the Tabei paleo-uplift, and deposition was later. This led to the lower and middle members of the Kepingtage Formation missing in that area. As a large-scale transgression occurred during the deposition period of the upper member of the Kepingtage Formation, sediment from the west of the basin was transported and deposited by tides and waves, forming tidal–marine debris systems above the uplift. Proximal alluvial fan and fan delta coarse clastic deposits developed in proximal uplift zone in the east and southeast of the basin, and braided delta put forward to the transitional zone between the edge of uplift and the sea. Large-scale tidal channel, sub-distributary channel and mouth bar of the delta front can form favorable reservoirs, and they are primary targets for oil and gas exploration. This research on sequence–depositional systems development and distribution controlled by palaeogeomorphology is significant in guiding the prediction of reservoir sandstones.Liu Jingyan Lin Changsong Cai Zhenzhong Zhu Yongfeng Yang Yongheng Peng Li Si Baoling Huang Zhen Li Huanpu Xu Yingcai Su Zhenzhen 2010Petroleum Science2010,7,3:13
2Activity and hydrothermal stability of CeO_2–ZrO_2–WO_3 for the selective catalytic reduction of NO_x with NH_3显示文摘A series of CeO_2–ZrO_2–WO_3(CZW)catalysts prepared by a hydrothermal synthesis method showed excellent catalytic activity for selective catalytic reduction(SCR)of NO with NH_3 over a wide temperature of 150–550°C.The effect of hydrothermal treatment of CZW catalysts on SCR activity was investigated in the presence of 10% H_2O.The fresh catalyst showed above 90% NO_x conversion at 201–459°C,which is applicable to diesel exhaust NO_x purification(200–440°C).The SCR activity results indicated that hydrothermal aging decreased the SCR activity of CZW at low temperatures(below 300°C),while the activity was notably enhanced at high temperature(above 450°C).The aged CZW catalyst(hydrothermal aging at 700°C for 8 hr)showed almost 80% NO_x conversion at 229–550°C,while the V_2O_5–WO_3/TiO_2 catalyst presented above 80% NO_x conversion at 308–370°C.The effect of structural changes,acidity,and redox properties of CZW on the SCR activity was investigated.The results indicated that the excellent hydrothermal stability of CZW was mainly due to the CeO_2–ZrO_2 solid solution,amorphous WO_3 phase and optimal acidity.In addition,the formation of WO_3 clusters increased in size as the hydrothermal aging temperature increased,resulting in the collapse of structure,which could further affect the acidity and redox properties.Zhongxian Song Ping Ning Qiulin Zhang Hao Li Jinhui Zhang Yancai Wang Xin Liu Zhenzhen Huang 2016Journal of Environmental Sciences2016,28,4:7

4On the Characteristic Polynomial of a Hexagonal System and Its Application显示文摘Let Ln be the hexagonal chain graph,Fnbe the hexacyclic system graph and Mn be the M¨obius hexacyclic system graph. Derflinger and Sofer gave the spectra of Ln and Fn by using group theoretical method. Later, Gutman gave the spectra of them using a polynomial result due to Godsil and McKay. In this paper, we give a simple and direct method to determine the characteristic polynomial and spectra of Fn and Ln. By the method, we give the characteristic polynomial and spectrum of Mn that is new. Additionally, the exact values of total π-electron energy and the nullities of Ln, Fn and Mn are obtained, and the bounds for the energy of Ln and Mn are also considered.Zhenzhen LOU Qiongxiang HUANG 2014Journal of Mathematical Research with Applications2014,34,3:5
5Effect of transcutaneous electrical nerve stimulation at acupoints on patients with type 2 diabetes mellitus:a randomized controlled trial显示文摘OBJECTIVE:To examine whether transcutaneous electric nerve stimulation at acupoints(Acu-TENS)improved the biochemical and physical indices of patients with type 2 diabetes mellitus(T2DM).METHODS:Ninety subjects with T2DM were divided randomly into a control group(n = 30),aerobic exercise group(n- 30),or Acu-TENS group(n = 30).In addition to conventional diabetes drug treatment,patients in the Acu-TENS group received acupoint stimulation,the aerobic exercise group engaged in walking exercises,and the control group was given sham electrical stimulation.All groups were treated for 30 min for each session and five times a week for 2 months.The indices of glycosylated hemoglobin,2 h postprandial glucose,fasting serum insulin,triglyceride,total cholesterol,and body mass index were assessed at pre-treatment,post-treatment,and follow-up,which was 2 months after treatment.RESULTS:The indices of the control group were not changed(P > 0.05) at the three time points.At the pre-treatment measurement,there were significant differences(P > 0.05) in indices among the three groups.At post-treatment,each index of the two groups was lower than that of the control group(P < 0.05),and improved in comparison with the pre-treatment measurement(P < 0.05).In follow-up,each index of the aerobic exercise group and Acu-TENS group increased,but was still decreased compared with the pre-treatment value(P < 0.05),excluding body mass index.CONCLUSION:Acu-TENS could improve the state of patients with T2 DM and be used as a therapy in clinical application.Wu Zhiyuan Yang Ming Jia Jie Wu Yi Huang Tiansheng Li Mingfen He Zhijie Guo Zhenzhen Leung Mason Chin Pang 2015Journal of Traditional Chinese Medicine2015,35,2:5
6An antioxidant system through conjugating superoxide dismutase onto metal-organic framework for cardiac repair显示文摘Acute myocardial infarction(AMI)remains a dominant origin of morbidity,mortality and disability worldwide.Increases in reactive oxygen species(ROS)are key contributor to excessive cardiac injury after AMI.Here we developed an immobilized enzyme with Superoxide Dismutase(SOD)activity cross-link with Zr-based metal-organic framework(ZrMOF)(SOD-ZrMOF)for mitigate ROS-caused injury.In vitro and in vivo evidence indicates that SOD-ZrMOF exhibits excellent biocompatibility.By efficiently scavenging ROS and suppressing oxidative stress,SOD-ZrMOF can protect the function of mitochondria,reduce cell death and alleviate inflammation.More excitingly,long-term study using an animal model of AMI demonstrated that SOD-ZrMOF can reduce the infarct area,protect cardiac function,promote angiogenesis and inhibit pathological myocardial remodeling.Therefore,SOD-ZrMOF holds great potential as an efficacious and safe nanomaterial treatment for AMI.Jiacheng Guo Zhenzhen Yang Yongzheng Lu Chunyan Du Chang Cao Bo Wang Xiaoting Yue Zenglei Zhang Yanyan Xu Zhen Qin Tingting Huang Wei Wang Wei Jiang Jinying Zhang Junnan Tang 2022Bioactive Materials2022,7,4:4
7A core-shell structured COYID-19 mRNA vaccine with favorable biodistribution pattern and promising immunity显示文摘Although inoculation of COVID-19 vaccines has rolled out globally,there is still a critical need for safe and effective vaccines to ensure fair and equitable supply for all countries.Here,we report on the development of a highly efficacious mRNA vaccine,SW0123 that is composed of sequence-modified mRNA encoding the full-length SARS-CoV-2 Spike protein packaged in core-shell structured lipopolyplex(LPP)nanoparticles.SWOT 23 is easy to produce using a large-scale microfluidics-based apparatus.The unique core-shell structured nanoparticle facilitates vaccine uptake and demonstrates a high colloidal stability,and a desirable biodistribution pattern with low liver targeting effect upon intramuscular administration.Extensive evaluations in mice and nonhuman primates revealed strong immunogenicity of SW0123,represented by induction of Th1-polarized T cell responses and high levels of antibodies that were capable of neutralizing not only the wild-type SARS-CoV-2,but also a panel of variants including D614G and N501Y variants.In addition,SW0123 conferred effective protection in both mice and non-human primates upon SARS-CoV-2 challenge.Taken together,SW0123 is a promising vaccine candidate that holds prospects for further evaluation in humans.Ren Yang Yao Deng Baoying Huang Lei Huang Ang Lin Yuhua Li Wenling Wang Jingjing Liu Shuaiyao Lu Zhenzhen Zhan Yufei Wang Ruhan A Wen Wang Peihua Niu Li Zhao Shiqiang Li Xiaopin Ma Luyao Zhang Yujian Zhang Weiguo Yao Xingjie Liang Jincun Zhao Zhongmin Liu Xiaozhong Peng Hangwen Li Wenjie Tan 2021Signal Transduction and Targeted Therapy2021,6,6:3
8AEG1通过激活NF-κB和AP-1诱导肝癌HepG2细胞COX-2表达(英文)显示文摘Objective:The aim of this study was to investigate whether astrocyte elevated gene 1 (AEG1) regulates COX-2 expression in human hepatoma HepG2 cells and related pathways involved in this process. Methods:Human hepatoma HepG2 cells were transfected with pcDNA3.1(-)-AEG1 plasmid or psilencer2.0-AEG1-shRNA1 plasmid to up/down-regulate AEG1 expression, pcDNA3.1(-) and psilencer 2.0 empty vector plasmids were transfected respectively as control. Real-time RT-PCR was carried out to measure the expression levels of AEG1 and COX-2 mRNA. The expression levels of AEG1 and COX-2 protein were detected by Western blot. NF-κB signaling was blocked by PDTC, and AP-1 signaling was blocked by curcumin. Results:AEG1 mRNA and protein levels were increased after pcDNA3.1(-)-AEG1 transfection, and decreased after psilencer2.0-AEG1-shRNAs transfection. COX-2 mRNA and protein levels were increased in AEG1-overexpressing cells and decreased in AEG1-knockdown cells. Phosphorylations of p65 and c-jun were up-regulated in AEG1-overexpressing cells. Both PDTC and curcumin reduced COX-2 expression in HepG2 cells with AEG1 overexpression. Conclusion:AEG1-overexpressing and-knockdown HepG2 cells are established successfully. AEG1 could induce COX-2 expression though activating NF-κB and AP-1 in human hepatoma HepG2 cells.Huan Deng Zhenzhen Zhou Wei Tu Yujia Xia Huanjun Huang De'an Tian 2013The Chinese-German Journal of Clinical Oncology2013,12,6:2
9Effects of silver nanoparticles with different dosing regimens and exposure media on artificial ecosystem显示文摘Due to the wide use of silver nanoparticles(AgNPs) in various fields, it is crucial to explore the potential negative impacts on the aquatic environment of AgNPs entering into the environment in different ways. In this study, comparative experiments were conducted to investigate the toxicological impacts of polyvinylpyrrolidone-coated silver nanoparticles(PVP-AgNPs) with two kinds of dosing regimens, continuous and one-time pulsed dosing, in different exposure media(deionized water and XiangJiang River water). There were a number of quite different experimental results(including 100% mortality of zebrafish,decline in the activity of enzymes, and lowest number and length of adventitious roots) in the one-time pulsed dosing regimen at high PVP-AgNP concentration exposure(HOE)compared to the three other treatments. Meanwhile, we determined that the concentration of leached silver ions from PVP-AgNPs was too low to play a role in zebrafish death. Those results showed that HOE led to a range of dramatic ecosystem impacts which were more destructive than those of other treatments. Moreover, compared with the continuous dosing regimen, despite the fact that higher toxicity was observed for HOE, there was little difference in the removal of total silver from the aquatic environment for the different dosing regimens. No obvious differences in ecological impacts were observed between different water columns under low concentration exposure. Overall, this work highlighted the fact that the toxicity of Ag NPs was impacted by different dosing regimens in different exposure media, which may be helpful for assessments of ecological impacts on aquatic environments.Jingwen Zeng Piao Xu Guiqiu Chen Guangming Zeng Anwei Chen Liang Hu Zhenzhen Huang Kai He Zhi Guo Weiwei Liu Jing Wu Jiangbo Shi 2019Journal of Environmental Sciences2019,31,1:2
10Lymphangiogenesis contributes to exercise-induced physiological cardiac growth显示文摘Background:Promoting cardiac lymphangiogenesis exerts beneficial effects for the heart.Exercise can induce physiological cardiac growth with cardiomyocyte hypertrophy and increased proliferation markers in cardiomyocytes.However,it remains unclear whether and how lymphangiogenesis contributes to exercise-induced physiological cardiac growth.We aimed to investigate the role and mechanism of lymphangiogenesis in exercise-induced physiological cardiac growth.Methods:Adult C57 BL6/J mice were subjected to 3 weeks of swimming exercise to induce physiological cardiac growth.Oral treatment with vascular endothelial growth factor receptor 3(VEGFR3) inhibitor SAR1 3 1 675 was used to investigate whether cardiac lymphangiogenesis was required for exercise-induced physiological cardiac growth by VEGFR3 activation.Furthermore,human dermal lymphatic endothelial cell(LEC)-conditioned medium was collected to culture isolated neonatal rat cardiomyocytes to determine whether and how LECs could influence cardiomyocyte proliferation and hypertrophy.Results:Swimming exercise induced physiological cardiac growth accompanied by a remarkable increase of cardiac lymphangiogenesis as evidenced by increased density of lymphatic vessel endothelial hyaluronic acid receptor 1-positive lymphatic vessels in the heart and upregulated LYVE-1 and Podoplanin expressions levels.VEGFR3 was upregulated in the exercised heart,while VEGFR3 inhibitor SAR131675 attenuated exercise-induced physiological cardiac growth as evidenced by blunted myocardial hypertrophy and reduced proliferation marker Ki67 in cardiomyocytes,which was correlated with reduced lymphatic vessel density and downregulated LYVE-1 and Podoplanin in the heart upon exercise.Furthermore,LEC-conditioned medium promoted both hypertrophy and proliferation of cardiomyocytes and contained higher levels of insulinlike growth factor-1 and the extracellular protein Reelin,while LEC-conditioned medium from LECs treated with SAR131675 blocked these effects.Functional rescue assays further demonstrated that protein kinase B(AKT) activation,as well as reduced CCAAT enhancer-binding protein beta(C/EBPβ) and increased CBP/p300-interacting transactivators with E(glutamic acid)/D(aspartic acid)-rich-carboxylterminal domain 4(CITED4),contributed to the promotive effect of LEC-conditioned medium on cardiomyocyte hypertrophy and proliferation.Conclusion:Our findings reveal that cardiac lymphangiogenesis is required for exercise-induced physiological cardiac growth by VEGFR3 activation,and they indicate that LEC-conditioned medium promotes both physiological hypertrophy and proliferation of cardiomyocytes through AKT activation and the C/EBPβ-CITED4 axis.These results highlight the essential roles of cardiac lymphangiogenesis in exercise-induced physiological cardiac growth.Yihua Bei Zhenzhen Huang Xing Feng Lin Li Meng Wei Yujiao Zhu Shuqin Liu Chen Chen Mingming Yin Huimin Jiang Junjie Xiao 2022Journal of Sport and Health Science2022,11,4:2
11rtcisE2F promotes the self-renewal and metastasis of liver tumorinitiating cells via N^(6)-methyladenosine-dependent E2F3/E2F6 mRNA stability显示文摘Liver cancer is highly heterogeneous,and the tumor tissue harbors a variety of cell types.Liver tumor initiating cells(TICs)well contribute to tumor heterogeneity and account for tumor initiation and metastasis,but the molecular mechanisms of liver TIC self-renewal are elusive.Here,we identified a functional read-through rt-circRNA,termed rtcisE2F,that is highly expressed in liver cancer and liver TICs.rtcisE2F plays essential roles in the self-renewal and activities of liver TICs.rtcisE2F targets E2F6 and E2F3 mRNAs,attenuates mRNA turnover,and increases E2F6/E2F3 expression.Mechanistically,rtcisE2F functions as a scaffold of N^(6)-methyladenosine(m^(6)A)reader IGF2BP2 and E2F6/E2F3 mRNA.rtcisE2F promotes the association of E2F6/E2F3 mRNAs with IGF2BP2,and inhibits their association with another m^(6)A reader,YTHDF2.IGF2BP2 inhibits E2F6/E2F3 mRNA decay,whereas YTHDF2 promotes E2F6/E2F3 mRNA decay.By switching m^(6)A readers,rtcisE2F enhances E2F6/E2F3 mRNA stability.E2F6 and E2F3 are both required for liver TIC self-renewal and Wnt/β-catenin activation,and inhibition of these pathways is a potential strategy for preventing liver tumorigenesis and metastasis.In conclusion,the rtcisE2F-IGF2BP2/YTHDF2-E2F6/E2F3-Wnt/β-catenin axis drives liver TIC self-renewal and initiates liver tumorigenesis and metastasis,and may provide a strategy to eliminate liver TICs.Zhenzhen Chen Lan Huang Kaili Wang Lulu Zhang Xiang Zhong Zhongyi Yan Benyu Liu Pingping Zhu 2022Science China(Life Sciences)2022,65,9:2
12Efficacy,safety and immunogenicity of hexavalent rotavirus vaccine in Chinese infants显示文摘A randomized,double-blind,placebo-controlled multicenter trial was conducted in healthy Chinese infants to assess the efficacy and safety of a hexavalent live human-bovine reassortant rotavirus vaccine(HRV)against rotavirus gastroenteritis(RVGE).A total of 6400 participants aged 6-12 weeks were enrolled and randomly assigned to either HRV(n?3200)or placebo(n?3200)group.All the subjects received three oral doses of vaccine four weeks apart.The vaccine efficacy(VE)against RVGE caused by rotavirus serotypes contained in HRV was evaluated from 14 days after three doses of administration up until the end of the second rotavirus season.VE against severe RVGE,VE against RVGE hospitalization caused by serotypes contained in HRV,and VE against RVGE,severe RVGE,and RVGE hospitalization caused by natural infection of any serotype of rotavirus were also investigated.All adverse events(AEs)were collected for 30 days after each dose.Serious AEs(SAEs)and intussusception cases were collected during the entire study.Our data showed that VE against RVGE caused by serotypes contained in HRV was 69.21%(95%CI:53.31-79.69).VE against severe RVGE and RVGE hospitalization caused by serotypes contained in HRV were 91.36%(95%CI:78.45-96.53)and 89.21%(95%CI:64.51-96.72)respectively.VE against RVGE,severe RVGE,and RVGE hospitalization caused by natural infection of any serotype of rotavirus were 62.88%(95%CI:49.11-72.92),85.51%(95%CI:72.74-92.30)and 83.68%(95%CI:61.34-93.11).Incidences of AEs from the first dose to one month post the third dose in HRV and placebo groups were comparable.There was no significant difference in incidences of SAEs in HRV and placebo groups.This study shows that this hexavalent reassortant rotavirus vaccine is an effective,well-tolerated,and safe vaccine for Chinese infants.Zhiwei Wu Qingliang Li Yan Liu Huakun Lv Zhaojun Mo Fangjun Li Qingchuan Yu Fei Jin Wei Chen Yong Zhang Teng Huang Xiaosong Hu Wei Xia Jiamei Gao Haisong Zhou Xuan Bai Yueyue Liu Zhenzhen Liang Zhijun Jiang Yingping Chen Jiuwei Zhang Jialiang Du Biao Yang Bo Xing Yantao Xing Ben Dong Qinghai Yang Chen Shi Tingdong Yan Bo Ruan Haiyun Shi Xingliang Fan Dongyang Feng Weigang Lv Dong Zhang Xiangchu Kong Liuyifan Zhou Dinghong Que Hong Chen Zhongbing Chen Xiang Guo Weiwei Zhou Cong Wu Qingrong Zhou Yuqing Liu Jian Qiao Ying Wang Xinguo Li Kai Duan Yuliang Zhao Gelin Xu Xiaoming Yang 2022Virologica Sinica2022,37,5:2

14Switching Optimally Balanced Fe-N Interaction Enables Extremely Stable Energy Storage显示文摘The interaction between electrode materials and charge carriers is one of the central issues dominating underlying energy storage mechanisms.To address the notoriously significant volume changes accompanying intercalation or formation of alloy/compounds,we aim to introduce and utilize a weak,reversible Fe-N interaction during the(de)intercalation of ammonium ions(NH_(4)^(+))within iron(Ⅲ)hexacyanoferrate(FeHCF),inspired by manipulating the electrostatic adsorption between N and Fe in the early stages of ammonia synthesis(Bosch-Harber Process,Chemical Engineering)and steel nitriding processes(Metal Industry).Such strategy of switching well-balanced Fe-N interaction is confirmed in between the nitrogen of ammonium ions and highspin Fe in FeHCF,as observed by using X-ray absorption spectroscopy.The resulting material provided an extremely stable energy storage(58 mAh g^(-1) after 10000 cycles at current density of 1 A g^(-1))as well as high-rate performance(23.6 mAh g^(-1) at current density of 10 A g^(-1)).Zhenzhen Zhao Wei Zhang Miao Liu Dong Wang Xiyang Wang Lirong Zheng Xu Zou Zizhun Wang Dabing Li Keke Huang Weitao Zheng 2023Energy & Environmental Materials2023,6,2:1

20Collaborative City Digital Twin for the COVID-19 Pandemic:A Federated Learning Solution显示文摘The novel coronavirus,COVID-19,has caused a crisis that affects all segments of the population.As the knowledge and understanding of COVID-19 evolve,an appropriate response plan for this pandemic is considered one of the most effective methods for controlling the spread of the virus.Recent studies indicate that a city Digital Twin(DT)is beneficial for tackling this health crisis,because it can construct a virtual replica to simulate factors,such as climate conditions,response policies,and people's trajectories,to help plan efficient and inclusive decisions.However,a city DTsystem relies on long-term and high-quality data collection to make appropriate decisions,limiting its advantages when facing urgent crises,such as the COVID-19 pandemic.Federated Learning(FL),in which all clients can learn a shared model while retaining all training data locally,emerges as a promising solution for accumulating the insights from multiple data sources efficiently.Furthermore,the enhanced privacy protection settings removing the privacy barriers lie in this collaboration.In this work,we propose a framework that fused city DT with FL to achieve a novel collaborative paradigm that allows multiple city DTs to share the local strategy and status quickly.In particular,an FL central server manages the local updates of multiple collaborators(city DTs),providing a global model that is trained in multiple iterations at different city DT systems until the model gains the correlations between various response plans and infection trends.This approach means a collaborative city DT paradigm fused with FL techniques can obtain knowledge and patterns from multiple DTs and eventually establish a'global view'of city crisis management.Meanwhile,it also helps improve each city's DT by consolidating other DT's data without violating privacy rules.In this paper,we use the COVID-19 pandemic as the use case of the proposed framework.The experimental results on a real dataset with various response plans validate our proposed solution and demonstrate its superior performance.Junjie Pang Yan Huang Zhenzhen Xie Jianbo Li Zhipeng Cai 2021Tsinghua Science and Technology2021,26,5:1
