1The pathological role of ferroptosis in ischemia/reperfusion-related injury显示文摘Ischemia/reperfusion(I/R) is a pathological process that occurs in numerous organs throughout the human body, and it is frequently associated with severe cellular damage and death. Recently it has emerged that ferroptosis, a new form of regulated cell death that is caused by iron-dependent lipid peroxidation, plays a significantly detrimental role in many I/R models. In this review, we aim to revise the pathological process of I/R and then explore the molecular pathogenesis of ferroptosis. Furthermore,we aim to evaluate the role that ferroptosis plays in I/R, providing evidence to support the targeting of ferroptosis in the I/R pathway may present as a therapeutic intervention to alleviate ischemia/reperfusion injury(IRI) associated cell damage and death.Hong-Fa Yan Qing-Zhang Tuo Qiao-Zhi Yin Peng Lei 2020Zoological Research2020,41,3:39
2Study of time-domain digital pulse shaping algorithms for nuclear signals显示文摘With the development on high-speed integrated circuit,fast high resolution sampling ADC and digital signal processors are replacing analog shaping amplifier circuit.This paper firstly presents the numerical analysis and simulation on R-C shaping circuit model and C-R shaping circuit model.Mathematic models are established based on 1st order digital differential method and Kirchhoff Current Law in time domain,and a simulation and error evaluation experiment on an ideal digital signal are carried out with Excel VBA.A digital shaping test for a semiconductor X-ray detector in real time is also presented.Then a numerical analysis for Sallen-Key(S-K) low-pass filter circuit model is implemented based on the analysis of digital R-C and digital C-R shaping methods.By applying the 2nd order non-homogeneous differential equation,the authors implement a digital Gaussian filter model for a standard exponential-decaying signal and a nuclear pulse signal.Finally,computer simulations and experimental tests are carried out and the results show the possibility of the digital pulse processing algorithms.ZHOU Jianbin ZHOU Wei LEI Jiarong TUO Xianguo ZHU Xing LIU Yi 2012Nuclear Science and Techniques2012,23,3:34
3Preconditioning and postconditioning reduce hepatic ischemia-reperfusion injury in rats显示文摘BACKGROUND:Ischemia-reperfusion injury occurs when ischemic tissues or organs suffer from further functional and structural damage when their blood supply recovers.This study aimed to contrast the protective effects of ischemic preconditioning and ischemic postconditioning in hepatic ischemia-reperfusion injury in rats.METHODS:Thirty-two healthy male Wistar rats were randomly divided into four groups:sham-operated(SO),ischemia-reperfusion(IR),ischemic preconditioning(I-pre),and ischemic postconditioning(I-post).Blood samples and hepatic tissue were taken from all groups after the experiments.RESULTS:There were significant differences between the IR,I-pre and I-post groups in alanine aminotransferase and aspartate aminotransferase levels,NF-κB p65 expression,apoptosis index and superoxide dismutase activity in hepatic tissue.There were no significant differences between the I-pre and I-post groups.CONCLUSIONS:Ischemic postconditioning and ischemic preconditioning reduce hepatic ischemia-reperfusion injury,but in clinical practice the former is a more appropriate choice.Zhang, Wan-Xing Yin, Wen Zhang, Lei Wang, Lan-Hui Bao, Lei Tuo, Hong-Fang Zhou, Li-Fang Wang, Chun-Cheng 2009Hepatobiliary & Pancreatic Diseases International2009,8,6:16
4Relationship between intestinal microbial dysbiosis and primary liver cancer显示文摘Background: Intestinal microbial dysbiosis is involved in liver disease pathogenesis. However, its role in primary liver cancer(PLC), particularly in hepatocarcinogenesis remains unclear. The present study aimed to study the changes in intestinal flora at various stages of PLC and clarify the relationship between intestinal microbes and PLC. Methods: Twenty-four patients with PLC(PLC group), 24 patients with liver cirrhosis(LC group), and 23 healthy control individuals(HC group) were enrolled from October 2016 to October 2017. Stool specimens of the participants were collected and the genomic DNA of fecal bacteria was isolated. High-throughput pyrosequencing of 16 S r DNA was used to identify differences in gut bacterial diversity among HC, LC, and PLC groups. We also analyzed the relationship between clinical factors and intestinal microorganisms in LC and PLC groups. Results: Diversity of Firmicutes tended to decrease from the HC to LC and PLC groups at the phylum level. Among species, Enterobacter ludwigii displayed an increasing trend in the PLC group, wherein the relative abundance of Enterobacter ludwigii in the PLC group was 100 times greater than that in the HC and LC groups. The ratio of Firmicutes/Bacteroidetes was significantly decreased with the disease progression. In addition, the linear discriminant analysis effect size method indicated that Clostridia were predominant in the gut microbiota of the HC group, whereas Enterococcaceae, Lactobacillales, Bacilli and Gammaproteobacteria may be used as diagnostic markers of PLC. Redundancy analysis showed a correlation between intestinal microbial diversity and clinical factors AST, ALT, and AFP. Veillonella showed a significant positive correlation with AFP in the PLC group, whereas Subdoligranulum showed a negative correlation with AFP. Conclusions: This study indicates that dysbiosis of the gut microbiota might be involved in PLC development and progression.Lei Zhang Yong-Na Wu Tuo Chen Cheng-Hui Ren Xun Li Guang-Xiu Liu 2019Hepatobiliary & Pancreatic Diseases International2019,18,2:16
5Ferroptosis:mechanisms and links with diseases显示文摘Ferroptosis is an iron-dependent cell death,which is different from apoptosis,necrosis,autophagy,and other forms of cell death.The process of feroptotic cell death is defined by the accumulation of lethal lipid species derived from the peroxidation of lipids,which can be prevented by iron chelators(e.g.deferiprone,deferoxamine)and small lipophilic antioxidants(e.g,ferrostatin,liproxstatin).This review summarizes current knowledge about the regulatory mechanism of ferroptosis and its association withseveral pathways,including iron,lipid,and cysteine metabolism.We have further discussed the contribution of ferroptosis to thepathogenesis of several diseases such as cancer,ischemia/reperfusion,and various neurodegenerative diseases(e.g.Alzheimersdisease and Parkinson's disease),and evaluated the therapeutic applications of ferroptosis inhibitors in clinics.Hong-fa Yan Ting Zou Qing-zhang Tuo Shuo Xu Hua Li Abdel Ali Belaidi Peng Lei 2021Signal Transduction and Targeted Therapy2021,6,3:16

7Granulocyte-macrophage colony-stimulating factor protects mice against hepatocellular carcinoma by ameliorating intestinal dysbiosis and attenuating inflammation显示文摘BACKGROUND Hepatocellular carcinoma(HCC)is the third leading cause of cancer mortality worldwide.The gut microbiota can help maintain healthy metabolism and immunity.Granulocyte-macrophage colony-stimulating factor(GM-CSF)is a critical factor in promoting health and homeostasis;it promotes intestinal immunity,stimulates bone marrow precursors to generate macrophage colonies,and enhances the antibacterial and antitumor activity of circulating monocytes.As such,GM-CSF may protect against HCC development by regulating immunity as well as intestinal microecology.AIM To investigate the impact of GM-CSF on the gut microbiome and metabolic characteristics of HCC.METHODS Thirty-six male BALB/c nude mice were divided into three groups:Control(n=10),HCC(n=13),and HCC+GM-CSF(GM-CSF overexpression,n=13).We utilized HCC cells to establish orthotopic transplantation tumor models of HCC with normal and over-expressing GM-CSF.Liver injury,immune inflammatory function and intestinal barrier function were evaluated.The fecal microbiome and metabolome were studied using 16S rRNA absolute quantification sequencing and gas chromatography-mass spectrometry.RESULTS GM-CSF overexpression significantly affected the gut microbiome of mice with HCC and resulted in a high abundance of organisms of the genera Roseburia,Blautia and Butyricimonass,along with a significant reduction in Prevotella,Parabacteroides,Anaerotruncus,Streptococcus,Clostridium,and Mucispirillum.Likewise,GM-CSF overexpression resulted in a substantial increase in fecal biotin and oleic acid levels,along with a prominent decrease in the fecal succinic acid,adenosine,fumaric acid,lipoic acid,and maleic acid levels.Correlation analysis revealed that the intestinal microbiota and fecal metabolites induced by GM-CSF were primarily involved in pathways related to reducing the inflammatory response,biotin metabolism,and intestinal barrier dysfunction.CONCLUSION GM-CSF can protect against HCC development by regulating immunity and modulating the abundance of specific intestinal microorganisms and their metabolites.This study provides new insights into the therapeutic approaches for HCC.Yong-Na Wu Lei Zhang Tuo Chen Xun Li Li-Hong He Guang-Xiu Liu 2020World Journal of Gastroenterology2020,26,36:4
8Stable Lithium-Carbon Composite Enabled by Dual-Salt Additives显示文摘Lithium metal is regarded as the ultimate negative electrode material for secondary batteries due to its high energy density.However,it suffers from poor cycling stability because of its high reactivity with liquid electrolytes.Therefore,continuous efforts have been put into improving the cycling Coulombic efficiency(CE)to extend the lifespan of the lithium metal negative electrode.Herein,we report that using dual-salt additives of LiPF_(6) and LiNO_(3) in an ether solvent-based electrolyte can significantly improve the cycling stability and rate capability of a Li-carbon(Li-CNT)composite.As a result,an average cycling CE as high as 99.30% was obtained for the Li-CNT at a current density of 2.5 mA cm^(-2) and an negative electrode to positive electrode capacity(N/P)ratio of 2.The cycling stability and rate capability enhancement of the Li-CNT negative electrode could be attributed to the formation of a better solid electrolyte interphase layer that contains both inorganic components and organic polyether.The former component mainly originates from the decomposition of the LiNO_(3) additive,while the latter comes from the LiPF_(6)-induced ring-opening polymerization of the ether solvent.This novel surface chemistry significantly improves the CE of Li negative electrode,revealing its importance for the practical application of lithium metal batteries.Lei Zheng Feng Guo Tuo Kang Yingzhu Fan Wei Gu Yayun Mao Ya Liu Rong Huang Zhiyun Li Yanbin Shen Wei Lu Liwei Chen 2021Nano-Micro Letters2021,13,7:3

10Monte-Carlo simulation of cement neutron field distribution characteristics in PGNAA显示文摘The distribution characteristics of the neutron field in cement was simulated using the MCNP code to comply with the requirements of an online Prompt Gamma Neutron Activation Analysis system.Simulation results showed that the neutron relative flux proportion reduced with increasing cement thickness.When the cement thickness remains unchanged,the reduced proportion of thermal neutrons increases to a small extent,but the epithermal, intermediate,and fast neutrons will decrease according to the geometric progression.H element in the cement mainly affects the reduction of fast neutrons and other single-substance elements,e.g.,O,Ca,56Fe,Si,and Al.It also slows down the reduction of the fast neutrons via inelastic scattering.O contributes more than other elements in the reduction of fast neutrons.Changing the H content affects the thermal,epithermal,intermediate,and fast neutrons, while changing the Ca,Fe,and Si contents only influences the thermal,epithermal,and intermediate neutrons;hence, there is little effect on the reduction of fast neutrons.YANG Jianbo YANG Yigang LI Yuanjing TUO Xianguo LI Zhe LIU Mingzhe CHENG Yi MU Keliang WANG Lei 2012Nuclear Science and Techniques2012,23,6:3
11Effect of Daxx on cholesterol accumulation in hepatic cells显示文摘AIM:To study the effect of Daxx on cholesterol accumulation in hepatic cells. METHODS: Sprague Dawley (SD) rats were fed a normal or high fat diet for 6 wk, and serum lipids and Daxx expression of hepatic tissues were measured by immunoblot assays. HepG2 cells were transfected with the pEGFP-C1/Daxx or pEGFP-C1 plasmid. Cells stably transfected with Daxx were identified by RT- PCR analysis. Total cholesterol levels were determined by high performance liquid chromatography. Activated- SREBP and caveolin-1 were assayed by western blotting. RESULTS: Hepatic Daxx protein was higher in normal rats than in high fat diet-fed rats. Noticeable negative correlations were seen between Daxx and LDL-C (γ = -7.56, P = 0.018), and between Daxx and TC (γ = -9.07, P = 0.01), respectively. The total cholesterol of HepG2/GFP-Daxx cells was lower than that of control cells or HepG2/GFP cells (9.28 ± 0.19 vs 14.36 ± 4.45 or 13.94 ± 2.62, both P < 0.05). Furthermore, in HepG2/GFP cells, the expression of activated SREBP was lower than that of control cells, whereas caveolin-1 expression was higher. CONCLUSION: Overexpression of Daxx in HepG2 cells decreased intracellular cholesterol accumulation, which might be associated with inhibition of SREBP activity and an increase in caveolin-1 expression.Qin-Hui Tuo Lei Liang Bing-Yang Zhu Xuan Cao Duan-Fang Liao 2008World Journal of Gastroenterology2008,14,3:3
12Thrombin induces ACSL4-dependent ferroptosis during cerebral ischemia/reperfusion显示文摘Ischemic stroke represents a significant danger to human beings,especially the elderly.Interventions are only available to remove the clot,and the mechanism of neuronal death during ischemic stroke is still in debate.Ferroptosis is increasingly appreciated as a mechanism of cell death after ischemia in various organs.Qing-zhang Tuo Yu Liu Zheng Xiang Hong-Fa Yan Ting Zou Yang Shu Xu-long Ding Jin-jun Zou Shuo Xu Fei Tang Yan-qiu Gong Xiao-lan Li Yu-jie Guo Zhao-yue Zheng Ai-ping Deng Zhang-zhong Yang Wen-jing Li Shu-ting Zhang Scott Ayton Ashley I.Bush Heng Xu Lunzhi Dai Biao Dong Peng Lei 2022Signal Transduction and Targeted Therapy2022,7,3:2
13Hierarchical Dispatch Method for Integrated Heat and Power Systems Based on a Feasible Region of Boundary Variables显示文摘Fully utilizing the flexibility provided by a district heating system(DHS)can promote wind power accommodation for an electric power system(EPS).However,for privacy or communication reasons,existing power and heat dispatch methods are not suitable for practical application.In this paper,a general math formulation of the hierarchical dispatch method is proposed to coordinate EPS and DHS operators based on the feasible region of boundary variables(FRBV),and a method based on the simplicial approximation approach is proposed to obtain a conservative FRBV approximation of a DHS.A simulation based on a real 41-node DHS is constructed to determine the factors that may impact the boundaries of the FRBV,and then the performance of the simplicial approximation approach is displayed by visualizing the approximation process for the FRBV,and finally three dispatch methods are compared to show the advantages of the proposed hierarchical dispatch method.Tuo Jiang Yong Min Weichun Ge Lei Chen Qun Chen Fei Xu Huanhuan Luo Guiping Zhou 2020CSEE Journal of Power and Energy Systems2020,6,3:2
14Simulation of an imaging system for internal contamination of lungs using MPA-MURA coded-aperture collimator显示文摘The nuclides inhaled during nuclear accidents usually cause internal contamination of the lungs with low activity.Although a parallel-hole imaging system,which is widely used in medical gamma cameras,has a high resolution and good image quality,owing to its extremely low detection efficiency,it remains difficult to obtain images of inhaled lung contamination.In this study,the Monte Carlo method was used to study the internal lung contamination imaging using the MPA-MURA coded-aperture collimator.The imaging system consisted of an adult male lung model,with a mosaicked,pattern-centered,and anti-symmetric MURA coded-aperture collimator model and a CsI(Tl)detector model.The MLEM decoding algorithm was used to reconstruct the internal contamination image,and the complementary imaging method was used to reduce the number of artifacts.The full width at half maximum of the I-131 point source image reconstructed by the MPAMURA coded-aperture imaging reached 2.51 mm,and the signal-to-noise ratio of the simplified respiratory tract source(I-131)image reconstructed through MPA-MURA coded-aperture imaging was 3.98 dB.Although the spatial resolution of MPA-MURA coded-aperture imaging is not as good as that of parallel-hole imaging,the detection efficiency of PMA-MURA coded-aperture imaging is two orders of magnitude higher than that of parallel-hole collimator imaging.Considering the low activity level of internal lung contamination caused by nuclear accidents,PMA-MURA coded-aperture imaging has significant potential for the development of lung contamination imaging.Ting Zhang Lei Wang Jing Ning Wei Lu Xiao-Fei Wang Hai-Wei Zhang Xian-Guo Tuo 2021Nuclear Science and Techniques2021,32,2:2
15A Genetic-Algorithm-based Neural Network Approach for Radioactive Activity Prediction显示文摘In this paper,a genetic-algorithm-based artificial neural network(GAANN)model radioactivity prediction is proposed,which is verified by measuring results from Long Range Alpha Detector(LRAD).GAANN can integrate capabilities of approximation of Artificial Neural Networks(ANN)and of global optimization of Genetic Algorithms(GA)so that the hybrid model can enhance capability of generalization and prediction accuracy,theoretically.With this model,both the number of hidden nodes and connection weights matrix in ANN are optimized using genetic operation.The real data sets are applied to the introduced method and the results are discussed and compared with the traditional Back Propagation(BP)neural network,showing the feasibility and validity of the proposed approach.WANG Lei TUO Xianguo YAN Yucheng LIU Mingzhe CHENG Yi LI Pingchuan 2013Nuclear Science and Techniques2013,24,6:2
16Elevated preoperative CA125 is associated with poor survival in patients with metastatic colorectal cancer undergoing primary tumor resection:a retrospective cohort study显示文摘Background The impact of the preoperative carbohydrate antigen 125(CA125)level on the survival of metastatic colorectal cancer(CRC)patients undergoing primary tumor resection(PTR)remains uncertain.The aim of this study was to assess the prognostic value in overall survival(OS)and cancer-specific survival(CSS)between patients with and without an elevated preoperative CA125 level.Methods All metastatic CRC patients receiving PTR between 2007 and 2017 at the Sixth Affiliated Hospital of Sun Yat-sen University(Guangzhou,China)were retrospectively included.OS and CSS rates were compared between patients with and without elevated preoperative CA125 levels.Results Among 326 patients examined,46(14.1%)exhibited elevated preoperative CA125 levels and the remaining 280(85.9%)had normal preoperative CA125 levels.Patients with elevated preoperative CA125 levels had lower body mass index,lower preoperative albumin level,lower proportion of preoperative chemotherapy,higher carcinoembryonic antigen and carbohydrate antigen 19–9(CA19–9)levels,poorer differentiation,and more malignant histopathological type than patients with normal preoperative CA125 levels.In addition,patients with elevated preoperative CA125 levels exhibited more advanced pathological T and N stages,more peritoneal metastasis,and more vessel invasion than patients with normal preoperative CA125 levels.Moreover,the primary tumor was more likely to be located at the colon rather than at the rectum in patients with elevated CA125 levels.Both OS and CSS rates in patients with elevated preoperative CA125 levels were significantly lower than those in patients with normal preoperative CA125 levels.Multivariate Cox regression analysis revealed that an elevated preoperative CA125 level was significantly associated with poor prognosis in metastatic CRC patients undergoing PTR.The hazard ratio(HR)in OS was 2.36(95%confidence interval[CI],1.67–3.33,P<0.001)and the HR in CSS was 2.50(95%CI,1.77–3.55,P<0.001).The survival analysis stratified by peritoneal metastasis also demonstrated that patients with elevated preoperative CA125 levels had lower OS and CSS rates regardless of peritoneal metastasis.Conclusion Based on an analysis of metastatic CRC patients undergoing PTR,an elevated preoperative CA125 level was associated with poor prognosis,which should be taken into consideration in clinical practice.Jun-Hua Huang Hua-Shan Liu Tuo Hu Zong-Jin Zhang Xiao-Wen He Tai-Wei Mo Xiao-Feng Wen Ping Lan Lei Lian Xian-Rui Wu 2022Gastroenterology Report2022,10,1:2

18Ferroptosis promotes T-cell activation-induced neurodegeneration in multiple sclerosis显示文摘While many drugs are effective at reducing the relapse frequency of multiple sclerosis (MS), there is an unmet need for treatments that slow neurodegeneration resulting from secondary disease progression. The mechanism of neurodegeneration in MS has not yet been established. Here, we discovered a potential pathogenetic role of ferroptosis, an iron-dependent regulated cell death mechanism, in MS. We found that critical ferroptosis proteins (acyl-CoA synthetase long-chain family member 4, ACSL4) were altered in an existing genomic database of MS patients, and biochemical features of ferroptosis, including lipid reactive oxygen species (ROS) accumulation and mitochondrial shrinkage, were observed in the experimental autoimmune encephalitis (EAE) mouse model. Targeting ferroptosis with ferroptosis inhibitors or reducing ACSL4 expression improved the behavioral phenotypes of EAE mice, reduced neuroinflammation, and prevented neuronal death. We found that ferroptosis was an early event in EAE, which may promote T-cell activation through T-cell receptor (TCR) signaling in vitro and in vivo. These data indicate that ferroptosis may be a potential target for treating MS.Jinyuan Luoqian Wenyong Yang Xulong Ding Qing-zhang Tuo Zheng Xiang Zhaoyue Zheng Yu-jie Guo Li Li Pengbo Guan Scott Ayton Biao Dong Huiyuan Zhang Hongbo Hu Peng Lei 2022Cellular & Molecular Immunology2022,19,8:2

20Highly stable lithium anode enabled by self-assembled monolayer of dihexadecanoalkyl phosphate显示文摘Li has been considered as the ultimate anode material for high energy density secondary Li batteries.However,its practical application has been limited due to its low Coulombic efficiency(CE)and the formation of lithium dendrites.Recently,we have developed a microspherical Li-carbon nanotube(Li-CNT)composite material passivated with octadecylphosphonic acid(OPA)self-assembled monolayer(SAM)exhibiting suppressed lithium dendrite formation and improved environmental/electrochemical stability.In this work,we demonstrated the significantly enhanced passivation effects of a SAM using dihexadecanoalkyl phosphate(DHP),a molecule that is comprised of double hydrophobic alkyl chains and forms a denser SAM on surfaces with large curvature.As a result,the DHP SAM delivers superior environmental and electrochemical stability to the OPA passivated Li-CNT material.In specific,the DHP passivated Li-CNT composite(DHP-Li-CNT)delivers a high CE of 99.25%under a 33.3%depth of discharge(DOD)at 1 C,when it is paired with a LiFePO4 cathode.The evolution of the SAM during cycling and the effects of DOD and current density on the CE of the DHP-Li-CNT anode have also been investigated.The improved SAM passivation constitutes an important step in achieving the goal of practically applicable Li anodes.Lei Zheng Feng Guo Tuo Kang Jin Yang Ya Liu Wei Gu Yanfei Zhao Hongzhen Lin Yanbin Shen Wei Lu Liwei Chen 2020Nano Research2020,13,5:1
