1Effect of artificial aeration on the performance of vertical-flow constructed wetland treating heavily polluted river water显示文摘Three lab-scale vertical-flow constructed wetlands(VFCWs),including the non-aerated(NA),intermittently aerated(IA) and continuously aerated(CA) ones,were operated at different hydraulic loading rates(HLRs) to evaluate the effect of artificial aeration on the treatment efficiency of heavily polluted river water.Results indicated that artificial aeration increased the dissolved oxygen(DO) concentrations in IA and CA,which significantly favored the removal of organic matter and NH 4 +-N.The DO grads caused by intermittent aeration formed aerobic and anoxic regions in IA and thus promoted the removal of total nitrogen(TN).Although the removal efficiencies of COD Cr,NH 4 +-N and TN in the three VFCWs all decreased with an increase in HLR,artificial aeration enhanced the reactor resistance to the fluctuation of pollutant loadings.The maximal removal efficiencies of COD Cr,NH 4 +-N and total phosphorus(TP)(i.e.,81%,87% and 37%,respectively) were observed in CA at 19 cm/day HLR,while the maximal TN removal(i.e.,57%) was achieved in IA.Although the improvement of artificial aeration on TP removal was limited,this study has demonstrated the feasibility of applying artificial aeration to VFCWs treating polluted river water,particularly at a high HLR.Huiyu Dong Zhimin Qiang Tinggang Li Hui Jin Weidong Chen 2012Journal of Environmental Sciences2012,24,4:38
2In-situ fabrication of PtSe2/GaN heterojunction for self-powered deep ultraviolet photodetector with ultrahigh current on/off ratio and detectivity显示文摘The research of ultraviolet photodetectors(UV PDs)have been attracting extensive attention,due to their important applications in many areas.In this study,PtSe2/GaN heterojunction is in-situ fabricated by synthesis of large-area vertically standing two-dimensional(2D)PtSe2 film on n-GaN substrate.The PtSe2/GaN heterojunction device demonstrates excellent photoresponse properties under illumination by deep UV light of 265 nm at zero bias voltage.Further analysis reveals that a high responsivity of 193 mA·W^-1,an ultrahigh specific detectivity of 3.8 × 10^14 Jones,linear dynamic range of 155d B and current on/off ratio of^10^8,as well as fast response speeds of 45/102μs were obtained at zero bias voltage.Moreover,this device response quickly to the pulse laser of 266 nm with a rise time of 172 ns.Such high-performanee PtSe2/GaN heteroj u nction UV PD demonstrated in this work is far superior to previously reported results,suggesting that it has great potential for deep UV detection.Ranran Zhuo Longhui Zeng Huiyu Yuan Di Wu Yuange Wang Zhifeng Shi Tingting Xu Yongtao Tian Xinjian Li Yuen Hong Tsang 2019Nano Research2019,12,1:11
3Combination of iTRAQ proteomics and RNA-seq transcriptomics reveals multiple levels of regulation in phytoplasma-infected Ziziphus jujuba Mill显示文摘Jujube witches’broom(JWB)is caused by infection with a phytoplasma.A multi-omics approach was taken during graft infection of jujube by JWB-infected scion through the analysis of the plant transcriptome,proteome and phytohormone levels.A high number of differentially expressed genes(DEGs)were identified 37 weeks after grafting(WAG),followed by observation of typical symptoms of JWB at 48 WAG.At 37 WAG,the majority of the upregulated DEGs and differentially expressed proteins(DEPs)were related to flavonoid biosynthesis,phenylalanine metabolism and phenylpropanoid biosynthesis.Two of the four upregulated proteins were similar to jasmonate-induced protein-like.Among the downregulated genes,the two most populated GO terms were plant–pathogen interaction and plant hormone signal transduction(mainly for tryptophan metabolism).Moreover,phytoplasma infection resulted in reduced auxin content and increased jasmonate content,indicating that auxin and jasmonic acid have important roles in regulating jujube responses during the first and second stages of phytoplasma infection.At 48 WAG,the two largest groups of upregulated genes were involved in phenylpropanoid biosynthesis and flavonoid biosynthesis.Both genes and proteins involved in carbon metabolism and carbon fixation in photosynthetic organisms were downregulated,indicating that photosynthesis was affected by the third stage of phytoplasma infection.Xia Ye Huiyu Wang Peng Chen Bing Fu Mengyang Zhang Jidong Li Xianbo Zheng Bin Tan Jiancan Feng 2017Horticulture Research2017,4,1:9
4Ultrasmall Fe-doped carbon dots nanozymes for photoenhanced antibacterial therapy and wound healing显示文摘Pathogenic bacteria pose a devastating threat to public health.However,because of the growing bacterial antibiotic resistance,there is an urgent need to develop alternative antibacterial strategies to the established antibiotics.Herein,iron-doped carbon dots(Fe-CDs,~3 nm)nanozymes with excellent photothermal conversion and photoenhanced enzyme-like properties are developed through a facile one-pot pyrolysis approach for synergistic efficient antibacterial therapy and wound healing.In particular,Fe doping endows CDs with photoenhanced peroxidase(POD)-like activity,which lead to the generation of heat and reactive oxygen species(ROS)for Gram-positive and Gram-negative bacteria killing.This study demonstrates Fe-CDs have significant wound healing efficiency of Fe-CDs by preventing infection,promoting fibroblast proliferation,angiogenesis,and collagen deposition.Furthermore,the ultrasmall size of Fe-CDs possesses good biocompatibility favoring clinical translation.We believe that the nanozyme-mediated therapeutic platform presented here is expected to show promising applications in antibacterial.Yunhang Liu Bolong Xu Mingzhu Lu Shanshan Li Juan Guo Fangzhou Chen Xiaolu Xiong Zhe Yin Huiyu Liu Dongsheng Zhou 2022Bioactive Materials2022,7,6:7
5Rational design of novel ultra-small amorphous Fe_(2)O_(3)nanodots/graphene heterostructures for all-solid-state asymmetric supercapacitors显示文摘Constructing graphene-based heterostructures with large interfacial area is an efficient approach to enhance the electrochemical performance of supercapacitors but remains great challenges in their synthesis.Herein,a novel ultra-small amorphous Fe_(2)O_(3)nanodots/graphene heterostructure(a-Fe_(2)O_(3)NDs/RGO)aerogel was facilely synthesized via excessive metal-ion-induced self-assembly and subsequent calcination route using Prussian blue/graphene oxide(PB/GO)composite aerogel as precursors.The deliberately designed a-Fe_(2)O_(3)NDs/RGO heterostructure offers a highly interconnected porous conductive network,large heterostructure interfacial area,and plenty of accessible active sites,greatly facilitating the electron transfer,electrolyte diffusion,and pseudocapacitive reactions.The obtained a-Fe_(2)O_(3)NDs/RGO aerogel could be used as flexible free-standing electrodes after mechanical compression,which exhibited a significantly enhanced specific capacitance of 347.4 F·g^(-1)at 1 A·g^(-1),extraordinary rate capability of 184 F·g^(-1)at 10 A·g^(-1),and decent cycling stability.With the as-prepared a-Fe_(2)O_(3)NDs/RGO as negative electrodes and the Co_(3)O_(4)NDs/RGO as positive electrodes,an all-solid-state asymmetric supercapacitor(a-Fe_(2)O_(3)NDs/RGO//Co_(3)O_(4)NDs/RGO asymmetric supercapacitor(ASC))was assembled,which delivered a high specific capacitance of 69.1 F·g^(-1)at 1 A·g^(-1)and an impressive energy density of 21.6 W·h·k·g^(-1)at 750 W·k·g^(-1),as well as good cycling stability with a capacity retention of 94.3%after 5,000 cycles.This work provides a promising avenue to design high-performance graphene-based composite electrodes and profound inspiration for developing advanced flexible energy-storage devices.Chenxiao Wu Zhifang Zhang Zhonghui Chen Zuimin Jiang Huiyu Li Haijing Cao Yongsheng Liu Yanyan Zhu Zebo Fang Xiangrong Yu 2021Nano Research2021,14,4:6
6Spleen-Yang-deficiency patients with polycystic ovary syndrome have higher levels of visfatin显示文摘OBJECTIVE:To study serum visfatin levels in women with polycystic ovary syndrome(PCOS)grouped by Traditional Chinese Medicine(TCM)patterns.To study the correlations of serum visfatin levels with homeostatic model assessment insulin resistance(HOMA-IR),fasting plasma glucose(FPG),fasting insulin(FINS),body mass index(BMI),testosterone(T),total cholesterol(TC),and triglycerides(TG).METHODS:Two hundred and twelve PCOS patients were placed into the following TCM pattern subgroups:Kidney-Yang deficiency(KYD)group,Spleen-Yang deficiency(SYD)group,stagnant Liver-Qi transforming into heat(SLQTH)group,and Kidney-Yin deficiency(KYIND)group.The correlations between serum visfatin levels and HOMA-IR,FPG,FINS,BMI,T,TC,andTG were analyzed.RESULTS:Of all patients with PCOS,there were 82in the KYD group(38.6%),67 in the SYD group(31.6%),37 in the SLQTH group(17.5%),and 26 in the KYIND group(12.3%).Visfatin levels in all PCOS subgroups were higher than those in the control group(P<0.01 or P<0.05).Among these subgroups,the visfatin levels in the SYD group were significantly higher than those in the other three TCM pattern groups(P<0.05).There were no statistical differences among the remaining three pattern groups.The levels of BMI,FINS,HOMA-IR,T,and TG were significantly higher in all subgroups than those in the control group(P<0.05).There were no significant differences in FPG and TC between all PCOS subgroups and the control group(P>0.05).The SYD group had higher levels of FINS and HOMA-IR compared with the KYD,SLQTH,and KYIND groups(P<0.05).In all subgroups,after controlling for BMI,TG,TC,and age,visfatin was positively correlated with FINS(r=0.197,P=0.015)and HOMA-IR(r=0.173,P=0.033),and was not correlated with T.CONCLUSION:KYD and SYD patterns are most common in PCOS patients.Increased visfatin is a common pathophysiologic manifestation in PCOS patients.The SYD group had the highest levels of visfatin,and visfatin was positively correlated with FINS and HOMA-IR.Huijia Fu Yan Qiu Feng Wei Li Yang Min Xia Huiyu He 2014Journal of Traditional Chinese Medicine2014,34,1:5
7High-yield preparation of robust gold nanoshells on silica nanorattles with good biocompatiblity显示文摘Although gold nanoshells are widely considered as one of the promising photothermal nanomaterials used for biomedicine, the high cost, low yield and poor stability severely limit their potential application in clinical trials.Herein, robust gold nanoshells on silica nanorattles(GSNs)were easily prepared in a high yield by an improved seedmediated method employing polyvinylpyrrolidone(PVP) as a stabilizing and capping agent. The present method is very simple, effective and reproducible and can well control the growth process of gold nanoshells. The as-prepared GSNs have a narrow size distribution(<10 % in standard deviation). Furthermore, the utilization rate of Au in the solution used for the growth of gold nanoshells increases by 70 %than that in previous method. The resultant GSNs have a good structural stability after placing over 6 months due to the protection of PVP. More importantly, in vivo and in vitro toxic studies indicate that the GSNs have good biocompatibility. We believe that our preparation method will remarkably promote the use of gold nanoshells for biomedicine.Changhui Fu Chaofeng He Longfei Tan Shunhao Wang Lu Shang Linlin Li Xianwei Meng Huiyu Liu 2016Science Bulletin2016,61,4:5
8BpMADS12 gene role in lignin biosynthesis of Betula platyphylla Suk by transcriptome analysis显示文摘MADS-box transcription factors show highly diverse regulatory functions in a wide variety of organisms.In this study,we characterized a MADS-box gene(BpMADS12) from the white birch(Betula platyphylla Suk).This gene is a member of the suppressor of overexpression of CO 1/tomato MADS 3 class of MADS-box genes.We generated lines overexpressing BpMADS12 and found that these had higher levels of lignin compared to that observed in nontransgenic lines.Transcriptome analysis revealed numerous changes in gene expression patterns.In total,8794 differentially expressed genes were identified,including 5006 upregulated unigenes and 3788 downregulated unigenes in Bp MADS-overexpression lines.Differentially expressed genes involved in the pathways for lignin and brassinosteroid biosynthesis were significantly enriched and may have contributed to phenotypic changes.The results from a quantitative RT-PCR analysis were consistent those obtained with the transcriptome analysis.Our transcriptome analysis,in combination with measurement of lignin level,indicated that Bp MADS12 promotes lignin synthesis through regulation of key enzymes in response to brassinosteroid signaling.These results suggest that this MADS-box protein is crucial to all subsequent structural events and provide a good foundation for studies aiming to elucidate the developmental mechanisms underlying formation of wood.Huiyu Li Yang Yang Zijia Wang Xiaohong Guo Feifei Liu Jing Jiang Guifeng Liu 2016Journal of Forestry Research2016,27,5:4
9Double lock of a potent human therapeutic monoclonal antibody against SARS-CoV-2显示文摘Receptor recognition and subsequent membrane fusion are essential for the establishment of successful infection by SARS-CoV-2.Halting these steps can cure COVID-19.Here we have identified and characterized a potent human monoclonal antibody,HB27,that blocks SARS-CoV-2 attachment to its cellular receptor at sub-nM concentrations.Remarkably,HB27 can also prevent SARS-CoV-2 membrane fusion.Consequently,a single dose of HB27 conferred effective protection against SARS-CoV-2 in two established mouse models.Rhesus macaques showed no obvious adverse events when administrated with10 times the effective dose of HB27.Cryo-EM studies on complex of SARS-CoV-2 trimeric S with HB27 Fab reveal that three Fab fragments work synergistically to occlude SARS-CoV-2 from binding to the ACE2 receptor.Binding of the antibody also restrains any further conformational changes of the receptor binding domain,possibly interfering with progression from the prefusion to the postfusion stage.These results suggest that HB27 is a promising candidate for immuno-therapies against COVID-19.Ling Zhu Yong-Qiang Deng Rong-Rong Zhang Zhen Cui Chun-Yun Sun Chang-Fa Fan Xiaorui Xing Weijin Huang Qi Chen Na-Na Zhang Qing Ye Tian-Shu Cao Nan Wang Lei Wang Lei Cao Huiyu Wang Desheng Kong Juan Ma Chunxia Luo Yanjing Zhang Jianhui Nie Yao Sun Zhe Lv Neil Shaw Qianqian Li Xiao-Feng Li Junjie Hu Liangzhi Xie Zihe Rao Youchun Wang Xiangxi Wang Cheng-Feng Qin 2021National Science Review2021,8,3:3

11HERG K+ channels expression in gastric cancers and analysis of its regulation in tumor cell proliferation and apoptosis显示文摘Objective:To investigate the expression of herg1 gene in tumor tissues from gastric carcinomas and gastric carcinoma cell lines,and study the relationship between HERG K+ channel expressions and tumor cell proliferation and apoptosis. Methods:RT-PCR and PCR assays were used to detect the expression of herg1 gene in 64 gastric carcinomas and the gastric cancer cell line SGC-7901. Blocking the HERG K+ channels was used to evaluate their effects on tumor cell proliferation and apoptosis. Results:The statistically significant expression of herg1 gene was detected in all the gastric cancers and SGC-7901 cells,but not in normal tissues. The HERG K+ channel blocker,E-4031,increased the cell population in G0/G1(P < 0.05) and the number of apoptotic tumor cells(P < 0.05). Conclusion:HERG K+ channels were expressed in all gastric carcinomas tested and these channels appear to modulate tumor cell proliferation and apoptosis.Qing Lu Huiyu Li Xiaoming Lu Guobin Wang 2009Journal of Nanjing Medical University2009,23,3:1

13Clinical Applications of Serum Anti-Mullerian Hormone€Measurements in Both Males and Females:An Update显示文摘Infertility is one of the most common non-communicable diseases,affecting both men and women equally.Ovarian reserve,the number of primordial follicles in the ovaries is believed to be the most important determinants for female fertility.Anti-Mullerian hormone(AMH)secreted from granulosa cells of growing follicles is recognized as the most important biomarker for ovarian reserve.Ovarian reserve models have been developed using AMH and other hormonal indicators,thus childbearing plans and reproductive choices could be arranged by women.In assisted reproductive technology cycles,measurement of AMH helps to predict ovarian response and guide recombinant follicle-stimulating hormone dosing in women.Serum AMH level is increasingly being recognized as a potential surrogate marker for polycystic ovarian morphology,one of the criteria for diagnosis of polycystic ovarian syndrome.AMH is also secreted by Sertoli cells of testes in men,and AMH measurements in the prediction of surgical sperm recovery rate in men have also been investigated.AMH levels are significantly higher in boys than in girls before puberty.Therefore,serum levels of AMH in combination with testosterone is used for the differential diagnosis of disorders of sex development,anorchia,non-obstructive azoospermia,and persistent Mullerian duct syndrome.Recently,serum AMH measurements have also been used in fertility preservation programs in oncofertility,screening for granulosa cell tumors,and prediction of menopause applications.In this review,we will focus on clinical application of AMH in fertility assessments for healthy men and women,as well as for cancer patients.Huiyu Xu Mengqian Zhang Hongxian Zhang Kannan Alpadi Lina Wang Rong Li Jie Qiao 2021The Innovation2021,2,1:1
14Realizing a“solid to solid”process via in situ cathode electrolyte interface(CEI)by solvent-in-salt electrolyte for Li-S batteries显示文摘Lithium-sulfur batteries(LSBs)are regarded as the most promising next-generation energy system due to their high theoretical energy density.However,LSBs suffer the“shuttle effect”if undergoing the solid-liquid-solid sulfur conversion process during cycling.Herein,we design a solvent-in-salt(SIS)electrolyte with co-solvent vinylene carbonate(VC)to synthesize an in situ dense cathode electrolyte interface(CEI)and successfully change sulfur conversion into a solid-solid way to avoid shuttle effect by separating the contact of sulfur and ether solvent.Dense CEI is formed at the beginning of first discharge by the combined action of SIS electrolyte and filmogen VC.Experiments and simulations show that SIS electrolyte controls the initial formed lithium polysulfides(LiPSs)to stay very closely on the cathode surface,and then converts them into a dense CEI film.As a result,Coulombic efficiency(above 99%)and cycling performance of LSBs are improved.Furthermore,the in situ dense CEI can nearly stop the self-discharge of LSBs,and enable the LSBs to work under a pretty lean electrolyte condition.Jiajun Huang Mengli Tao Weifeng Zhang Guangli Zheng Li Du Zhiming Cui Xiujun Wang Zhenxing Liang Shijun Liao Huiyu Song 2023Nano Research2023,16,4:1

17A bioactive nanocomposite sponge for simultaneous hemostasis and antimicrobial therapy显示文摘Uncontrollable bleeding and bacterial infections are the major reasons for the high mortality of post-traumatic.In this study,a composite hemostatic chitosan sponge CaO_(2)@SiO_(2)/CS was prepared by combining a novel core-shell inorganic nano hemostatic CaO_(2)@SiO_(2)nanoparticles with carboxylated chitosan,which presents a multi-layered structure with a rough and hydrophilic surface for rapid absorption of blood.When the CaO_(2)@SiO_(2)nanoparticles in the CaO_(2)@SiO_(2)/CS come into contact with blood,the silanol group on its surface and the released H_(2)O_(2)and Ca2+can recruit and activate platelets,while generating fibrin clots and activating the endo-exogenous coagulation cascade reaction to achieve rapid clotting.The H_(2)O_(2)released from CaO_(2)@SiO_(2)shows the antimicrobial capacity and stimulates the production of tissue factors by endothelial cells.Meanwhile,the silica coating reduces the cytotoxicity of bare CaO_(2),thus reducing the risk of secondary bleeding at the site of vascular injury.CaO_(2)@SiO_(2)/CS(48 s)showed a 1.83-and 2.52-fold reduction in hemostasis time compared to commercial gelfoam and CS in a femoral artery hemorrhage model.This study illustrates the hemostatic mechanism of CaO_(2)@SiO_(2)and provides a reference for the development of clinical biomedical inorganic hemostatic materials.Jiani Lei Shanshan Li Shuang Liu Qingyuan Wu Bolong Xu Zhijun Huang Nier Wu Xiaolu Xiong Huiyu Liu Dongsheng Zhou 2023Nano Research2023,16,3:1
18Improved electrochemical hydrogen storage properties of Mg-Y thin films as a function of substrate temperature显示文摘Pd-capped Mg_(78)Y_(22) thin films have been prepared by direct current magnetron co-sputtering system at different substrate temperatures and their electrochemical hydrogen storage properties have been investigated.It is found that rising substrate temperature to 60 ℃ can coarsen the surface of thin film,thus facilitating the diffusion of hydrogen atoms and then enhancing its discharge capacity to ~1725 mAh·g^(-1).Simultaneously,the cyclic stability is effectively improved due to the increased adhesion force between film and substrate as a function of temperature.In addition,the specimen exhibits a very long and flat discharge plateau at about —0.67 V,at which nearly 60%of capacity is maintained.The property is favorable for the application in metal hydride/nickel secondary batteries.The results indicate that rising optimal substrate temperature has a beneficial effect on the electrochemical hydrogen storage of Mg-Y thin films.Yanyan Wang Gongbiao Xin Chongyun Wang Huiyu Li Wei Li Jie Zheng Xingguo Li 2014Journal of Energy Chemistry2014,23,3:1

20HERG1 K^+ Channels on the Leukemic Cells Mediated Angiogenesis in vitro显示文摘Human ether-a-go-go-related gene(HERGl) K^+ channels are overexpressed in leukemia,which contributes to neoangiogenesis.The purpose of this study was to investigate the role of HERGl K^+ channels on leukemia angiogenesis.We cultured human umbilical vein endothelial cells(HUVECs) in conditioned media,which were derived from leukemic cells with or without E-4031,a HERGl K+ channel special inhibitor.The HUVECs proliferation was measured using CCK-8 assay and migration by a Trans-well.Endothelial tube formation was investigated using Matrigel.Vascular endothelial growth factor(VEGF) levels were tested by ELISA and VEGF mRNA expression using RT-PCR.Our results revealed that blocking HERGl K^+ channels could inhibit leukemia-induced HUVECs proliferation,migration,and tube formation in vitro.The results suggested that HERGl K^+ channels could increase leukemia angiogenesis.Furthermore,blockage of HERGl K^+ channels could also decrease leukemic cells secreting VEGF and expressing VEGF mRNA.HERGl K channels have a promoting effect on leukemia angiogenesis,and the possible mechanism may be that HERGl K^+channels enhance VEGF expression.Thus,HERGl K channel is a potential target of antiangiogenesis in leukemia.LI Huiyu GUO Dongmei ZHENG Fang LIANG Kaiwei LI Wenying JIE Shenghua 2014Wuhan University Journal of Natural Sciences2014,19,2:1
