| 2 | Long-and short-chain AHLs affect AOA and AOB microbial community composition and ammonia oxidation rate in activated sludge显示文摘Quorum sensing(QS)regulation of the composition of ammonia-oxidising archaea(AOA)and ammonia-oxidising bacteria(AOB)communities and functions in wastewater treatment was investigated.Specifically,we explored the role of N-acyl-L-homoserine lactones(AHLs)in microbial community dynamics in activated sludge.On average,the specific ammoniaoxidising-rate increased from 1.6 to 2.8 mg NH_4^+-N/g MLSS/hr after treatment with long-chain AHLs for 16 days,and the addition of AHLs to sludge resulted in an increased number of AOA/AOB amoA genes.Significant differences were observed in the AOA communities of control and AHL-treated cultures,but not the AOB community.Furthermore,the dominant functional AOA strains of the Crenarchaeota altered their ecological niche in response to AHL addition.These results provide evidence that AHLs play an important role in mediating AOA/AOB microbial community parameters and demonstrate the potential for application of QS to the regulation of nitrogen compound metabolism in wastewater treatment. | Jie Gao Yu Duan Ying Liu Xuliang Zhuang Yichen Liu Zhihui Bai Wenlin Ma Guoqiang Zhuang | 2019 | Journal of Environmental Sciences2019，31，4： | 11 |
| 3 | Predictive factors associated with gefitinib response in patients with advanced non-small-cell lung cancer(NSCLC)显示文摘Purpose: A number of different clinical characteristics have been reported to singly correlate with therapeutic activity of epidermal growth factor receptor(EGFR) tyrosine kinase inhibitors(TKIs) in advanced non-small-cell lung cancer(NSCLC). This study aimed to identify predictive factors associated with prognostic benefits of gefitinib.Patients and methods: EGFR gene typing in 33 advanced NSCLC patients received gefitinib(250 mg/day) were analyzed with mutant-enriched PCR assay. Gefitinib response was evaluated with potential predictive factors retrospectively.Results: The overall objective response rate(ORR) and median progression-free survival(PFS) in the 33 patients treated by gefitinib were 45.5% and 3.0(2.0-4.0) months. The ORR and median PFS in EGFR gene mutation patients were significantly higher/longer than those in EGFR gene wild-type patients(P<0.01). Similarly, the ORR and median PFS in non-smoker patients were significantly higher/longer than those in smoker patients(P<0.05, P<0.01, respectively). However, no difference for ORR and median PFS occurred between male and female patients. Logistic multivariate analysis showed that only EGFR mutated gene was significantly associated with the ORR(P<0.01). Both EGFR mutated gene and non-smoker were the major factors that contributed to PFS(P<0.05). Conclusions: EGFR mutated gene and non-smoker status are potential predictors for gefitinib response in NSCLC patients. | Lian Chen Rui Chen Zhe Zhu Yichen Zhang Zhengwei Wen Yun Li Xiaoming Li Yuwen Luo Liyu Ma Shuguang Lin Xin Chen | 2014 | Chinese Journal of Cancer Research2014，26，4： | 7 |
| 4 | Cell sheet formation enhances the therapeutic effects of human umbilical cord mesenchymal stem cells on myocardial infarction as a bioactive material显示文摘Stem cell-based therapy has been used to treat ischaemic heart diseases for two decades.However,optimal cell types and transplantation methods remain unclear.This study evaluated the therapeutic effects of human umbilical cord mesenchymal stem cell(hUCMSC)sheet on myocardial infarction(MI).Methods:hUCMSCs expressing luciferase were generated by lentiviral transduction for in vivo bio-luminescent imaging tracking of cells.We applied a temperature-responsive cell culture surface-based method to form the hUCMSC sheet.Cell retention was evaluated using an in vivo bio-luminescent imaging tracking system.Unbiased transcriptional profiling of infarcted hearts and further immunohistochemical assessment of monocyte and macrophage subtypes were used to determine the mechanisms underlying the therapeutic effects of the hUCMSC sheet.Echocardiography and pathological analyses of heart sections were performed to evaluate cardiac function,angiogenesis and left ventricular remodelling.Results:When transplanted to the infarcted mouse hearts,hUCMSC sheet significantly improved the retention and survival compared with cell suspension.At the early stage of MI,hUCMSC sheet modulated inflammation by decreasing Mcp1-positive monocytes and CD68-positive macrophages and increasing Cx3cr1-positive non-classical macrophages,preserving the cardiomyocytes from acute injury.Moreover,the extracellular matrix produced by hUCMSC sheet then served as bioactive scaffold for the host cells to graft and generate new epicardial tissue,providing mechanical support and routes for revascularsation.These effects of hUCMSC sheet treatment significantly improved the cardiac function at days 7 and 28 post-MI.Conclusions:hUCMSC sheet formation dramatically improved the biological functions of hUCMSCs,mitigating adverse post-MI remodelling by modulating the inflammatory response and providing bioactive scaffold upon transplantation into the heart.Translational perspective:Due to its excellent availability as well as superior local cellular retention and survival,allogenic transplantation of hUCMSC sheets can more effectively acquire the biological functions of hUCMSCs,such as modulating inflammation and enhancing angiogenesis.Moreover,the hUCMSC sheet method allows the transfer of an intact extracellular matrix without introducing exogenous or synthetic biomaterial,further improving its clinical applicability. | Rui Guo Feng Wan Masatoshi Morimatsu Qing Xu Tian Feng Hang Yang Yichen Gong Shuhong Ma Yun Chang Siyao Zhang Youxu Jiang Heqing Wang Dehua Chang Hongjia Zhang Yunpeng Ling Feng Lan | 2021 | Bioactive Materials2021，6，9： | 6 |
| 5 | 3D Bioprinting:A Novel Avenue for Manufacturing Tissues and Organs显示文摘Three-dimensional(3D)bioprinting is a rapidly growing technology that has been widely used in tissue engineering,disease studies,and drug screening.It provides the unprecedented capacity of depositing various types of biomaterials,cells,and biomolecules in a layer-by-layer fashion,with precisely controlled spatial distribution.This technology is expected to address the organ-shortage issue in the future.In this review,we first introduce three categories of 3D bioprinting strategies:inkjet-based printing(IBP),extrusion-based printing(EBP),and light-based printing(LBP).Biomaterials and cells,which are normally referred to as“bioinks,”are then discussed.We also systematically describe the recent advancements of 3D bioprinting in fabricating cell-laden artificial tissues and organs with solid or hollow structures,including cartilage,bone,skin,muscle,vascular network,and so on.The development of organs-onchips utilizing 3D bioprinting technology for drug discovery and toxicity testing is reviewed as well.Finally,the main challenges in current studies and an outlook of the future research of 3D bioprinting are discussed. | Bin Zhang Lei Gao Liang Ma Yichen Luo Huayong Yang Zhanfeng Cui | 2019 | Engineering2019，5，4： | 5 |
| 6 | Nickel and indium core-shell co-catalysts loaded silicon nanowire arrays for efficient photoelectrocatalytic reduction of CO_(2) to formate显示文摘Developing an efficient artificial photosynthetic system for transforming carbon dioxide and storing solar energy in the form of chemical bonds is one of the greatest challenges in modern chemistry.However,the limited choice of catalysts with wide light absorption range,long-term stability and excellent selectivity for CO_(2) reduction makes the process sluggish.Here,a core-shell-structured nonnoble-metal Ni@In co-catalyst loaded p-type silicon nanowire arrays(SiNWs)for efficient CO_(2) reduction to formate is demonstrated.The formation rate and Faradaic efficiency of formate over the Ni@In/SiNWs catalyst reach 58μmol h^(-1) cm^(-2) and 87% under the irradiation of one simulated sunlight(AM 1.5 G,100 mW cm^(-2)),respectively,which are about 24 and 12 times those over the pristine SiNWs.The enhanced photoelectrocatalytic performance for CO_(2) reduction is attributed to the rational combination of Ni capable of effectively extracting the photogenerated electrons and In responsible for the selective activation of CO_(2). | Wenchao Ma Mingcan Xie Shunji Xie Longfu Wei Yichen Cai Qinghong Zhang Ye Wang | 2021 | Journal of Energy Chemistry2021，30，3： | 3 |
| 7 | The Msi1-mTOR pathway drives the pathogenesis of mammary and extramammary Paget’s disease显示文摘Mammary and extramammary Paget’s Diseases(PD)are a malignant skin cancer characterized by the appearance of Paget cells.Although easily diagnosed,its pathogenesis remains unknown.Here,single-cell RNA-sequencing identified distinct cellular states,novel biomarkers,and signaling pathways—including mTOR,associated with extramammary PD.Interestingly,we identified MSI1 ectopic overexpression in basal epithelial cells of human PD skin,and show that Msi1 overexpression in the epidermal basal layer of mice phenocopies human PD at histopathological,single-cell and molecular levels.Using this mouse model,we identified novel biomarkers of Paget-like cells that translated to human Paget cells.Furthermore,single-cell trajectory,RNA velocity and lineage-tracing analyses revealed a putative keratinocyte-to-Paget-like cell conversion,supporting the in situ transformation theory of disease pathogenesis.Mechanistically,the Msi1-mTOR pathway drives keratinocyte-Paget-like cell conversion,and suppression of mTOR signaling with Rapamycin significantly rescued the Paget-like phenotype in Msi1-overexpressing transgenic mice.Topical Rapamycin treatment improved extramammary PD-associated symptoms in humans,suggesting mTOR inhibition as a novel therapeutic treatment in PD. | Yongli Song Christian F.Guerrero-Juarez Zhongjian Chen Yichen Tang Xianghui Ma Cong Lv Xueyun Bi Min Deng Lina Bu Yuhua Tian Ruiqi Liu Ran Zhao Jiuzhi Xu Xiaole Sheng Sujuan Du Yeqiang Liu Yunlu Zhu Shi-jun Shan Hong-duo Chen Yiqiang Zhao Guangbiao Zhou Jianwei Shuai Fazheng Ren Lixiang Xue Zhaoxia Ying Xing Dai Christopher J.Lengner Bogi Andersen Maksim V.Plikus Qing Nie Zhengquan Yu-Show | 2020 | Cell Research2020，30，10： | 2 |

| 9 | Plasma reforming of toluene as a model tar compound from biomass gasification:effect of CO_(2) and steam显示文摘In this study, plasma reforming of toluene as a tar model compound from biomass gasification has been carried out using an AC gliding arc discharge reactor. The influence of steam and CO_(2) addition on the reforming of toluene has been evaluated. The results show that the highest toluene conversion (59.9%) was achieved when adding 3 vol% CO_(2) at a toluene concentra-tion of 16.1 g/Nm3 and a specific energy input of 0.25 kWh/m3. Further increasing CO_(2) concentration to 12 vol% decreased the conversion of toluene. The presence of steam in the plasma CO_(2) reforming of toluene creates oxidative OH radicals which contribute to the enhanced conversion of toluene and energy efficiency of the plasma reforming process through stepwise oxidation of toluene and reaction intermediates. Hydrogen and C_(2)H_(2) were identified as the major gas products in the plasma reforming of toluene without CO_(2) or steam, with a yield of 9.7% and 14.5%, respectively, while syngas was the primary products with a maximum yield of 58.3% (27.5% for H_(2) and 30.8% for CO) in the plasma reforming with the addition of 12 vol% CO_(2). The plausible reaction pathways and mechanism in the plasma reforming of toluene have been proposed through the combination of the analysis of gas and condensed products and spectroscopic diagnostics. | Shiyun Liu Danhua Mei Yaolin Wang Yichen Ma Xin Tu | 2019 | Waste Disposal and Sustainable Energy2019，1，2： | 2 |
| 10 | Formation mechanism of the Lidang circular structure in the Guangxi Province显示文摘The Lidang circular structure in the center of the Guangxi Province is about 8 km in diameter. This structure appears as an abnormal shallow depression that has disturbed the rather harmonic regional joint systems. Its unique occurrence in the whole region, the circular morphology, negative topography, and the spatial distribution of interior and exterior strata are all consistent with those of impact craters that are formed by asteroidal or cometary collision. To test the impact hypothesis, we carried out both field investigation and remote sensing study of this structure. Regional geological history suggests that if the impact hypothesis were correct, the impact event should have occurred at or after the Early Permian. Field investigation found that the strata inside and outside the crater are dominated by parallel stacks of Lower and Upper Permian limestone that have various thicknesses and different mud contents. The layers of limestone within and outside the circular structure have identical attitudes;no structural disturbances were visible in the outcrops. Field investigations provide conclusive evidence against the impact cratering hypothesis. A high-resolution digital elevation model shows that the spatial distribution of rounded mountains within the structure is controlled by faint but continual extension of joints, suggesting that the crater interior has gone through a much higher degree of erosion. Therefore, regional joints that had once existed within the crater are preserved less well than exterior terrains, forming the abruptly disrupted circular depression. Differential erosion, as the possible formation mechanism of the Lidang structure, is consistent with the different mud contents found between the interior and exterior limestone. The circular outline of this structure may correspond to the shape of the original deposition basin. In conclusion, the Lidang circular structure is a polje formed by karstification, not an astrobleme. | Pan Yan ZhiYong Xiao YiZhen Ma YiChen Wang Jiang Pu | 2019 | Earth and Planetary Physics2019，3，4： | 2 |

| 14 | The crosstalk between ferroptosis and anti-tumor immunity in the tumor microenvironment:molecular mechanisms and therapeutic controversy显示文摘The advent of immunotherapy has significantly reshaped the landscape of cancer treatment,greatly enhancing therapeutic outcomes for multiple types of cancer.However,only a small subset of individuals respond to it,underscoring the urgent need for new methods to improve its response rate.Ferroptosis,a recently discovered form of programmed cell death,has emerged as a promising approach for anti-tumor therapy,with targeting ferroptosis to kill tumors seen as a potentially effective strategy.Numerous studies suggest that inducing ferroptosis can synergistically enhance the effects of immunotherapy,paving the way for a promising combined treatment method in the future.Nevertheless,recent research has raised concerns about the potential negative impacts on anti-tumor immunity as a consequence of inducing ferroptosis,leading to conflicting views within the scientific community about the interplay between ferroptosis and anti-tumor immunity,thereby underscoring the necessity of a comprehensive review of the existing literature on this relationship.Previous reviews on ferroptosis have touched on related content,many focusing primarily on the promoting role of ferroptosis on anti-tumor immunity while overlooking recent evidence on the inhibitory effects of ferroptosis on immunity.Others have concentrated solely on discussing related content either from the perspective of cancer cells and ferroptosis or from immune cells and ferroptosis.Given that both cancer cells and immune cells exist in the tumor microenvironment,a one-sided discussion cannot comprehensively summarize this topic.Therefore,from the perspectives of both tumor cells and tumor-infiltrating immune cells,we systematically summarize the current conflicting views on the interplay between ferroptosis and anti-tumor immunity,intending to provide potential explanations and identify the work needed to establish a translational basis for combined ferroptosis-targeted therapy and immunotherapy in treating tumors. | Yichen Zheng Lingqi Sun Jiamin Guo Ji Ma | 2023 | Cancer Communications2023，43，10： | 1 |
