3Early Serum HBsAg Kinetics as Predictor of HBsAg Loss in Patients with HBeAg-Negative Chronic Hepatitis B after Treatment with Pegylated Interferonα-2a显示文摘Hepatitis B surface antigen(HBsAg)loss is an ideal treatment endpoint for patients with chronic hepatitis B(CHB).We investigated the predictive value of on-treatment HBsAg levels for HBsAg loss in hepatitis B e antigen(HBe Ag)-negative CHB patients who received 120-week PEG-IFNα-2a treatment.Serum HBV DNA,HBsAg,and anti-HBs levels were assayed at baseline and every 3 months during the treatment.Of 81 patients,12 achieved HBsAg loss,20 achieved HBsAg\100 IU/mL,and 49 maintained HBs Ag C 100 IU/mL.HBsAg loss rate was only 3.7%at 48 weeks,while it reached to 11.1%and 14.8%after treatment of 96 weeks and 120 weeks.The cutoff HBs Ag levels at 12 weeks predicting HBsAg loss at 96 weeks and 120 weeks of treatment were 400 IU/mL and 750 IU/mL,with AUC 0.725 and 0.722,positive predictive value(PPV)29.41%and 30.56%,and negative predictive value(NPV)93.75%and 97.78%,respectively.The cutoff HBsAg levels at 24 weeks predicting HBsAg loss at 96 weeks and 120 weeks of treatment were 174 IU/m L and 236 IU/mL respectively,with AUC 0.925 and 0.922,PPV 40.0%and 46.15%,and both NPV 100%.The predictive ability of the cutoff HBsAg levels at 24 weeks was better than that at 12 weeks for HBs Ag loss at either 96 or 120 weeks(χ~2=3.880,P=0.049 andχ~2=4.412,P=0.036).These results indicate that extended therapy is critical to HBsAg loss in HBe Ag-negative CHB patients during PEG-IFN treatment,and the HBsAg level at 24 weeks can be used to predict HBsAg loss during tailoring PEG-IFN therapy.Minghui Li Lu Zhang Yao Lu Qiqi Chen Huihui Lu Fangfang Sun Zhan Zeng Gang Wan Linqing Zhao Yao Xie 2021Virologica Sinica2021,36,2:15
4Role of pyroptosis in inflammation and cancer显示文摘Pyroptosis is a form of programmed cell death mediated by gasdermin and is a product of continuous cell expansion until the cytomembrane ruptures,resulting in the release of cellular contents that can activate strong inflammatory and immune responses.Pyroptosis,an innate immune response,can be triggered by the activation of inflammasomes by various influencing factors.Activation of these inflammasomes can induce the maturation of caspase-1 or caspase-4/5/11,both of which cleave gasdermin D to release its N-terminal domain,which can bind membrane lipids and perforate the cell membrane.Here,we review the latest advancements in research on the mechanisms of pyroptosis,newly discovered influencing factors,antitumoral properties,and applications in various diseases.Moreover,this review also provides updates on potential targeted therapies for inflammation and cancers,methods for clinical prevention,and finally challenges and future directions in the field.Xiang Wei Feng Xie Xiaoxue Zhou Yuchen Wu Haiyan Yan Ting Liu Jun Huang Fangwei Wang Fangfang Zhou Long Zhang 2022Cellular & Molecular Immunology2022,19,9:11
5Ferroptosis in cancer and cancer immunotherapy显示文摘The hallmark of tumorigenesis is the successful circumvention of cell death regulation for achieving unlimited replication and immortality.Ferroptosis is a newly identified type of cell death dependent on lipid peroxidation which differs from classical programmed cell death in terms of morphology,physiology and biochemistry.The broad spectrum of injury and tumor tolerance are the main reasons for radiotherapy and chemotherapy failure.The effective rate of tumor immunotherapy as a new treatment method is less than 30%.Ferroptosis can be seen in radiotherapy,chemotherapy,and tumor immunotherapy;therefore,fer-roptosis activation may be a potential strategy to overcome the drug resistance mechanism of traditional cancer treatments.In this review,the characteristics and causes of cell death by lipid peroxidation in ferroptosis are briefly described.In addition,the three metabolic regulations of ferroptosis and its crosstalk with classical signaling pathways are summarized.Collectively,these findings sug-gest the vital role of ferroptosis in immunotherapy based on the interaction of ferroptosis with tumor immunotherapy,chemotherapy and radiotherapy,thus,indicating the remarkable potential of ferroptosis in cancer treatment.Lei Zhao Xiaoxue Zhou Feng Xie Lei Zhang Haiyan Yan Jun Huang Chong Zhang Fangfang Zhou Jun Chen Long Zhang 2022Cancer Communications2022,42,2:10
6The function and clinical application of extracellular vesicles in innate immune regulation显示文摘The innate immune system plays a crucial role in the host defense against viral and microbial infection.Exosomes constitute a subset of extracellular vesicles(EVs)that can be released by almost all cell types.Owing to their capacity to shield the payload from degradation and to evade recognition and subsequent removal by the immune system,exosomes efficiently transport functional components to recipient cells.Accumulating evidence has recently shown that exosomes derived from tumor cells,host cells and even bacteria and parasites mediate the communication between the invader and innate immune cells and thus play an irreplaceable function in the dissemination of pathogens and donor cell-derived molecules,modulating the innate immune responses of the host.In this review,we describe the current understanding of EVs(mainly focusing on exosomes)and summarize and discuss their crucial roles in determining innate immune responses.Additionally,we discuss the potential of using exosomes as biomarkers and cancer vaccines in diagnostic and therapeutic applications.Xiaoxue Zhou Feng Xie Lin Wang Long Zhang Suping Zhang Meiyu Fang Fangfang Zhou 2020Cellular & Molecular Immunology2020,17,4:6
7Scalable salt-templated directed synthesis of high-quality MoS_(2) nanosheets powders towards energetic and environmental applications显示文摘Two-dimensional(2D)transition metal dichalcogenides(TMDCs)have emerged as perfect platforms for developing applications in nano-electronics,catalysis,energy storage and environmental-related fields due to their superior properties.However,the low-cost,batch production of high-quality 2D TMDCs remains a huge challenge with the existing synthetic strategies.Herein,we present a scalable chemical vapor deposition(CVD)approach for the batch production of high-quality MoS_(2) nanosheet powders,by using naturally abundant,water-soluble and recyclable NaCl crystal powders as templates.The high-quality MoS_(2) nanosheets powders are achieved by a facile water dissolution-filtration process,by virtue of the excellent dispersibility of the as-grown products in water.The internal mechanism for the scalable synthesis strategy is explored.The applications of the MoS_(2) nanosheets powders are also demonstrated as catalysts or adsorbents in hydrogen evolution reaction(HER)and organic dyes adsorption,respectively.This work should hereby pave ways for the mass production and application of powdery TMDCs in energetic and environmental related fields.Lijie Zhu Pengfei Yang Yahuan Huan Shuangyuan Pan Zhaoqian Zhang Fangfang Cui Yuping Shi Shaolong Jiang Chunyu Xie Min Hong Jiatian Fu Jingyi Hu Yanfeng Zhang 2020Nano Research2020,13,11:4
8A simple solvothermal route towards the morphological control of ZnO and tuning of its optical and photocatalytic properties显示文摘ZnO nanoparticles with different morphologies were solvothermally synthesized by controlling the alkali (sodium hydroxide) concentration in an isopropanol solution.The products were characterized by means of powder X-ray diffraction,UV-visible absorption spectra,scanning electron microscopy,transmission electron microscopy,and selected area electron diffraction.The morphologies of the formed ZnO nanocrystals were dependent on the concentration of the alkali,and with increases of sodium hydroxide concentration,the ZnO nanocrystals evolved from rod to hexagonal bipyramid,and then to a flower-like nanostructure.The flower-like nanostructure resulted from the etching of the hexagonal bipyramid by the excess alkali.The photoluminescence and photocatalytic properties of the prepared ZnO were investigated.The difference of green emission among the ZnO nanocrystals indicated that a higher sodium hydroxide concentration led to a higher level of defects.The size,the surface structure and defects in the ZnO nanocrystals affected its photo-degradation characteristics.JIANG YaQi,LI FangFang,SUN Ran,XIE ZhaoXiong & ZHENG LanSun State Key Laboratory for Physical Chemistry of Solid Surfaces Department of Chemistry,College of Chemistry and Chemical Engineering,Xiamen University,Xiamen 361005,China 2010Science China Chemistry2010,53,8:3
9Association between physical activity and digestive-system cancer: An updated systematic review and meta-analysis显示文摘Background:Physical activity(PA)may have an impact on digestive-system cancer(DSC)by improving insulin sensitivity and anticancer immune function and by reducing the exposure of the digestive tract to carcinogens by stimulating gastrointestinal motility,thus reducing transit time.The current study aimed to determine the effect of PA on different types of DSC via a systematic review and meta-analysis.Methods:In accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses(PRISMA)guidelines,we searched for relevant studies in PubMed,Embase,Web of Science,Cochrane Library,and China National Knowledge Infrastructure.Using a random effects model,the relationship between PA and different types of DSC was analyzed.Results:The data used for meta-analysis were derived from 161 risk estimates in 47 studies involving 5,797,768 participants and 55,162 cases.We assessed the pooled associations between high vs.low PA levels and the risk of DSC(risk ratio(RR)=0.82,95%confidence interval(95%CI):0.79-0.85),colon cancer(RR=0.81,95%CI:0.76-0.87),rectal cancer(RR=0.88,95%CI:0.80-0.98),colorectal cancer(RR=0.77,95%CI:0.69-0.85),gallbladder cancer(RR=0.79,95%CI:0.64-0.98),gastric cancer(RR=0.83,95%CI:0.76-0.91),liver cancer(RR=0.73,0.60-0.89),oropharyngeal cancer(RR=0.79,95%CI:0.72-0.87),and pancreatic cancer(RR=0.85,95%CI:0.78-0.93).The findings were comparable between case-control studies(RR=0.73,95%CI:0.68-0.78)and prospective cohort studies(RR=0.88,95%CI:0.80-0.91).The meta-analysis of 9 studies reporting low,moderate,and high PA levels,with 17 risk estimates,showed that compared to low PA,moderate PA may also reduce the risk of DSC(RR=0.89,95%CI:0.80-1.00),while compared to moderate PA,high PA seemed to slightly increase the risk of DSC,although the results were not statistically significant(RR=1.11,95%CI:0.94-1.32).In addition,limited evidence from 5 studies suggested that meeting the international PA guidelines might not significantly reduce the risk of DSC(RR=0.96,95%CI:0.91-1.02).Conclusion:Compared to previous research,this systematic review has provided more comprehensive information about the inverse relationship between PA and DSC risk.The updated evidence from the current meta-analysis indicates that a moderate-to-high PA level is a common protective factor that can significantly lower the overall risk of DSC.However,the reduction rate for specific cancers may vary.In addition,limited evidence suggests that meeting the international PA guidelines might not significantly reduce the risk of DSC.Thus,future studies must be conducted to determine the optimal dosage,frequency,intensity,and duration of PA required to reduce DSC risk effectively.Fangfang Xie Yanli You Jihan Huang Chong Guan Ziji Chen Min Fang Fei Yao Jia Han 2021Journal of Sport and Health Science2021,10,1:3
10The interactions between cGAS-STING pathway and pathogens显示文摘Cytosolic DNA is an indicator of pathogen invasion or DNA damage.The cytosolic DNA sensor cyclic guanosine monophosphateadenosine monophosphate(cGAMP)synthase(cGAS)detects DNA and then mediates downstream immune responses through the molecule stimulator of interferon genes(STING,also known as MITA,MPYS,ERIS and TMEM173).Recent studies focusing on the roles of the cGAS-STING pathway in evolutionary distant species have partly sketched how the mammalian cGAS-STING pathways are shaped and have revealed its evolutionarily conserved mechanism in combating pathogens.Both this pathway and pathogens have developed sophisticated strategies to counteract each other for their survival.Here,we summarise current knowledge on the interactions between the cGAS-STING pathway and pathogens from both evolutionary and mechanistic perspectives.Deeper insight into these interactions might enable us to clarify the pathogenesis of certain infectious diseases and better harness the cGAS-STING pathway for antimicrobial methods.Zhangliang Cheng Tong Dai Xuelin He Zhengkui Zhang Feng Xie Shuai Wang Long Zhang Fangfang Zhou 2020Signal Transduction and Targeted Therapy2020,5,1:3
11ATP11B deficiency leads to impairment of hippocampal synaptic plasticity显示文摘Synaptic plasticity is known to regulate and support signal transduction between neurons, while synaptic dysfunction contributes to multiple neurological and other brain disorders;however, the specific mechanism underlying this process remains unclear. In the present study, abnormal neural and dendritic morphology was observed in the hippocampus following knockout of Atpllb both in vitro and in vivo. Moreover, ATP11B modified synaptic ultrastructure and promoted spine remodeling via the asymmetrical distribution of phosphatidylserine and enhancement of glutamate release, glutamate receptor expression, and intracellular Ca^2+ concentration. Fuithermoe experimental results also indicate that ATP11B regulated synaptic plasticity in hippocampal neurons through the MAPK14 signaling pathway. In conclusion, our data shed light on the possible mechanisms underlying the regulation of synaptic plasticity and lay the foundation for the exploration of proteins involved in signal transduction during this process.Jiao Wang Weihao Li Fangfang Zhou Ruili Feng Fushuai Wang Shibo Zhang Jie Li Qian Li Yajiang Wang Jiang Xie Tieqiao Wen 2019Journal of Molecular Cell Biology2019,11,8:2

16Controlled Growth of Pt–Au Alloy Nanowires and Their Performance for Formic Acid Electrooxidation显示文摘Pt–Au alloy nanowires have been controllably electrodeposited on microelectrodes by applying an alternating current and were used as the electrocatalyst for formic acid oxidation. The frequency and voltage of the alternating current and the electrolyte composition were adjusted to precisely control the morphologies, alloying structures and composition. The characteristics of Pt–Au alloy nanowires were analyzed by scanning electron microscopy, X-ray diffraction and transmission electron spectroscopy. Electrocatalytic performance of formic acid oxidation at Pt–Au alloy nanowires electrode was investigated by cyclic voltammetry and chronoamperometry. The results showed that the Pt–Au alloy nanowires possessed highlycrystalline morphologies, the controllable bimetallic composition and single-phase alloy structures, which mainly grow in the <111> crystal orientation. The electrocatalytic activity of formic acid oxidation strongly depended on the bimetallic Pt/Au composition. The Pt35Au65 alloy nanowires displayed superior electrocatalytic performance and high stability toward the electrooxidation of formic acid in acidic solution, owing to the ensemble effect of the Pt and Au components. These ?ndings provided insights into the design of the Pt–Au bimetallic nanomaterials as electrocatalysts for formic acid oxidation.Yu Han Yuejun Ouyang Zhihui Xie Jinri Chen Fangfang Chang Gang Yu 2016Journal of Materials Science & Technology2016,32,7:1
17Comprehensive investigation of HBV-related hepatocellular carcinoma and choice of anti-HBV therapy显示文摘Chronic hepatitis B virus(HBV)infection is a global public health problem,which can cause chronic hepatitis,liver cirrhosis,hepatocellular carcinoma(HCC),and other diseases.Antiviral therapy is the most critical measure to slow down the progression of chronic hepatitis B,prevent or delay cirrhosis,HCC,and other kinds of liver decompensation events.At present,the anti-hepatitis B virus drugs are mainly nucleoside(acid)analogues(NAs)and interferon.Each kind of antiviral drug has different effects on the clinical outcome of hepatitis B patients(such as HCC).In this paper,we discussed the biological characteristics,natural course and prognosis of HBV infection,the mechanism of HBV-related HCC,the effect of different antiviral drugs on patients’outcome,predictive biomarkers and model for HBV clinical outcome,predictors of sustained response and recurrence after withdrawal of antiviral therapy,consideration of expanding therapeutic indications and antiviral therapy,hoping to give a hand to the clinical diagnosis and treatment of HBV.Huihui Lu Wei Yi Fangfang Sun Zhan Zeng Lu Zhang Minghui Li Yao Xie 2021Biosafety and Health2021,3,4:1
18Reasonable location of stopping line in close‑distance underlying coal seam and partition support of large cross‑section roadway显示文摘Close-distance coal seams are widely distributed over China,and the coal pillars left by the overlying coal seams afect the retracement channel of the underlying coal seam in the stopping stage.Based on the engineering background of close-distance seam mining in a coal mine,the reasonable position of the underlying coal seam's stopping line and the support method of the large section roadway during stopping are investigated using feld measurements,similar simulation experiments,and numerical simulations.There are three types of location relationships between the stopping line of the underlying coal seam and the stopping line of the overlying coal seam:'externally staggered with the upper stopping line'(ESUL,stops mining under the overlying goaf),'overlapped with upper stopping line'(OUL),and'internally staggered with the upper stopping line'(ISUL,ISUL-SD for shorter internal staggered distances,ISUL-LD for longer ones).There are diferent stress arch structures in the overlying strata of the above three positions,and the stress arch evolution process exists in the process of ESUL→OUL→ISUL-SD→ISUL-LD:a front and rear double stress arch structure→the front arch gradually decreases→the front arch dies out,and the double arch synthesizes the single arch→the single-arch range expands→the nested double arch.The relationship between the stress arch structure and the position of the stopping line is evaluated as follows:(1)ESUL:the stress concentration in the roof plate of the retracement channel of the underlying coal seam is the highest,because the overburden block of the extensive collapse zone acts directly on the roof plate of the retracement channel,resulting in relative difculties in roof support.(2)OUL:although the retracement channel roof pressure is minimal,the overlying rock structure has the potential for rotation or slippage instability.(3)ISUL-SD:the pressure on the roof of the retracement channel is small and the overburden structure is stable,which is conducive to the safe retraction of the support and not limited by the width of the end-mining coal pillar.(4)ISUL-LD:it is basically the same as the condition of stopping under the non-goaf;however,it has a limitation on the width of the end-mining coal pillar.The location of the stopping line is selected as ISUL-SD,and the retraction process of the self-excavating retraction channel was adopted.A partition asymmetric support scheme which is proven by feld practice is proposed,through a comprehensive analysis of the pre-stress feld simulation of the support scheme,based on the diferent control requirements of the roof above the support and the roof of the retracement channel in the stopping area.This method realizes safe and smooth withdrawal of the support.Dongdong Chen Yiyi Wu Shengrong Xie Fangfang Guo Fulian He Ruipeng Liu 2022International Journal of Coal Science & Technology2022,9,4:1

20Improving ORR activity of carbon nanotubes by hydrothermal carbon deposition method显示文摘Nitrogen doped carbons are an important family of materials with ideal activity for oxygen reduction reaction(ORR). It is always interesting to search functional carbons with high heteroatom contents and desirable structure for ORR. Within this study, the surface modification of carbon nanotubes(CNTs) via hydrothermal carbonization(HTC) technique in the presence of glucose and urea was reported, where the surface of CNTs is successfully coated by nitrogen containing hydrothermal carbon layers. The resulting composite combines both advantages of the outstanding electrical conductivity of CNTs and the effective ORR active sites provided by doped nitrogen in the HTC carbon layers. By controlling the ratio of glucose and urea, the nitrogen contents coated on the surface of CNTs can reach up to 1.7 wt%. The resulting materials show outstanding electrochemical activity towards ORR in alkaline electrolyte, making it one of the valuable metal-free electrode materials and a competent alternative to the state-of-the-art Pt/C catalyst.Baobing Huang Lu Peng Fangfang Yang Yuchuan Liu Zailai Xie 2017Journal of Energy Chemistry2017,26,4:1
