4An-Luo-Hua-Xian Pill Improves the Regression of Liver Fibrosis in Chronic Hepatitis B Patients Treated with Entecavir显示文摘Background and Aims:Chronic hepatitis B(CHB)can cause liver fibrosis and lead to cirrhosis and cancer.As the effectiveness of antiviral therapy to reverse liver fibrosis is limited,We aimed to evaluate the effect of An-Luo-Hua-Xian pill(ALHX)on fibrosis regression in CHB patients treated with entecavir(ETV).Methods:Treatment-naïve patients with CHB were randomly treated with ETV alone or combined with ALHX(ETV+ALHX)between October 1,2013 and December 31,2020.Demographic,laboratory,and liver histology data before and after 78 weeks of treatment were collected.The Ishak fibrosis score(F)was used and fibrosis regression required a decrease in F of≥1 after treatment.Results:A total of 780 patients were enrolled,and 394 with a second liver biopsy after treatment were included in the per-protocol population,132 in ETV group and 262 in ETV+ALHX group.After 78 weeks of treatment,the fibrosis regression rate in the ETV+ALHX group was significantly higher than that of the ETV group at baseline F≥3 patients:124/211(58.8%)vs.45/98(45.9%),p=0.035.The percentage of patients with a decreased liver stiffness measurement(LSM)was higher in the ETV+ALHX group:156/211(73.9%)vs.62/98(63.%),p=0.056.Logistic regression analysis showed that ETV combined with ALHX was associated with fibrosis regression[odds ratio(OR)=1.94,p=0.018],and a family history of hepatocellular carcinoma was on the contrary.(OR=0.41,p=0.031).Conclusions:ETV combined with ALHX increased liver fibrosis regression in CHB patients.Yi-Qi Liu Chi Zhang Jia-Wen Li Li-Hua Cao Zhan-Qing Zhang Wei-Feng Zhao Qing-Hua Shang Da-Zhi Zhang An-Lin Ma Qing Xie Hong-Lian Gui Guo Zhang Ying-Xia Liu Jia Shang Shi-Bin Xie Jun Li Xu-Qing Zhang Zhi-Qiang Zou Yu-Ping Chen Zong Zhang Ming-Xiang Zhang Jun Cheng Fu-Chun Zhang Li-Hua Huang Jia-Bin Li Qing-Hua Meng Hai-Bin Yu Yu-Qiang Mi Yan-Zhong Peng Zhi-Jin Wang Li-Ming Chen Fan-Ping Meng Wan-Hua Ren Lang Bai Yi-Lan Zeng Rong Fan Xian-Zhi Lou Wei-Feng Liang Hui Liu Hui Zhuang Hong Zhao Gui-Qiang Wang 2023Journal of Clinical and Translational Hepatology2023,11,2:7
5Experimental and numerical study on fretting wear and fatigue of full-scale railway axles显示文摘This study investigated the fretting wear and fatigue of full-scale railway axles.Fatigue tests were conducted on full-scale railway axles,and the fretting wear and fretting fatigue in the fretted zone of the railway axles were analysed.Three-dimensional finite element models were established based on the experimental results.Then,multi-axial fatigue parameters and a linear elastic fracture mechanics-based approach were used to investigate the fretting fatigue crack initiation and propagation,respectively,in which the role of the fretting wear was taken into account.The experimental and simulated results showed that the fretted zone could be divided into zones I-III according to the surface damage morphologies.Fretting wear alleviated the stress concentration near the wheel seat edge and resulted in a new stress concentration near the worn/unworn boundary in zone II,which greatly promoted the fretting crack initiation at the inner side of the fretted zone.Meanwhile,the stress concentration also increased the equivalent stress intensity factor range DKeq below the mating surface,and thus promoted the propagation of fretting fatigue crack.Based on these findings,the effect of the stress redistribution resulting from fretting wear is suggested to be taken into account when evaluating the fretting fatigue in railway axles.Lang Zou Dongfang Zeng Yabo Li Kai Yang Liantao Lu Caiqin Yuan 2020Railway Engineering Science2020,28,4:7
6ERK1/2-mediated Cytoplasmic Accumulation of hnRNPK Antagonizes TRAIL-induced Apoptosis through Upregulation of XIAP in H1299 Cells显示文摘Objective Tumor necrosis factor-related apoptosis-inducing ligand(TRAIL) resistance greatly limits the clinical therapeutic efficacy of TRAIL. Elucidating the molecular mechanism underlying TRAIL resistance will be fundamental to resolving this problem. Methods Nuclear and cytoplasmic protein extraction and immunofluorescence(IF) assay were used to detect changes in heterogeneous nuclear ribonucleoprotein K(hn RNPK) localization in H1299 cells. The evaluation of cell apoptosis in cells transfected with GFP-hn RNPK, GFP-hn RNPK S284/353 A, or GFP-hn RNPK S284/353 D mutant was performed using cleaved caspase-3 antibody. The gene expression of XIAP was tested by quantitative RT-PCR. Results Previously, we reported that hn RNPK antagonized TRAIL-induced apoptosis through inhibition of PKC-mediated GSK3β phosphorylation. In this study, we further demonstrate that TRAIL treatment induces cytoplasmic accumulation of hn RNPK in H1299 cells. The hn RNPK localized in the cytoplasm has a higher capacity to antagonize TRAIL-induced apoptosis. Both ERK1/2 signaling inhibitor U0126 and ERK-phosphoacceptor-site mutant(GFP-hn RNPK S284/353A) diminish cytoplasmic accumulation of hn RNPK induced by TRAIL. Moreover, we show that XIAP is involved in hn RNPK-mediated TRAIL resistance in H1299 cells. Conclusion Taken together, these results give new insights into the understanding of the molecular mechanism associated with TRAIL resistance in lung adenocarcinoma.HUANG Wen Si XU Feng Mei ZENG Qing Zhong LIU Xiao Hui GAO Xue Juan LIU Lang Xia 2017Biomedical and Environmental Sciences2017,30,7:5
7TiO_2-coated SnO_2 hollow spheres as anode materials for lithium ion batteries显示文摘TiO2-coated SnO2(TCS) hollow spheres,which are new anode materials for lithium ion(Li-ion) batteries,were prepared and characterized with X-ray diffraction(XRD) ,scanning electron microscopy(SEM) ,transmission electron microscopy(TEM) ,cyclic voltammetry(CV) ,and galvanostatic charge/discharge tests.The results obtained from XRD,SEM,and TEM show that TiO2 can be uniformly coated on the surface of SnO2 hollow spheres with the assistance of anionic surfactant.The cyclic voltammograms indicate that both TiO2 and SnO2 ex-hibit the activity for Li-ion storage.The charge/discharge tests show that the prepared TCS hollow spheres have a higher reversible coulomb efficiency and a better cycling stability than the uncoated SnO2 hollow spheres.YI Jin LI Xiaoping HU Shejun LI Weishan ZENG Ronghua FU Zhao CHEN Lang 2011Rare Metals2011,30,6:4
8Urban-rural disparities in mild cognitive impairment and its functional subtypes among community- dwelling older residents in central China显示文摘background Substantial variations in the prevalence of mild cognitive impairment(MCI)and its subtypes have been reported,although mostly in geographically defined developed countries and regions.Less is known about MCI and its subtypes in rural areas of less developed central China.Aims The study aimed to compare the prevalence of MCI and its subtypes in residents aged 65 years or older in urban and rural areas of Hubei Province,China.Methods Participants aged 65 years or older were recruited between 2018 and 2019.Inperson structured interviews and clinical and neuropsychological assessments were performed at city health community centres and township hospitals.results Among 2644 participants without dementia,735 had MCI,resulting in a prevalence of 27.8%for total MCI,20.9%for amnestic MCI(aMCI)and 6.9%for non-amnestic MCI(naMCI).The prevalence of MCI in urban and rural areas was 20.2%and 44.1%,respectively.After adjusting for demographic factors,the prevalence of total MCI,aMCI and naMCI differed significantly between rural and urban areas(adjusted odds ratio(OR)2.10,1.44 and 3.76,respectively).Subgroup analysis revealed an association between rural socioeconomic and lifestyle disadvantage and MCI and its subtypes.Conclusions Our findings suggest that the prevalence of MCI among urban residents in central China is consistent with that in other metropolis areas,such as Shanghai,but the prevalence in rural areas is twice that in urban areas.Prospective studies and dementia prevention in China should focus on rural areas.Dan Liu Lin Li Lina An Guirong Cheng Cong Chen Mingjun Zou Bo Zhang Xuguang Gan Lang Xu Yangming Ou Qingming Wu Ru Wang Yan Zeng 2021General Psychiatry2021,34,5:3
9Systemic autoimmune diseases and recurrent pregnancy loss:research progress in diagnosis and treatment显示文摘To the Editor:Recurrent pregnancy loss(RPL)is defined as the loss of two or more pregnancies before 24 weeks of gestation,and it affects about 1%to 2%of couples.[1]The etiology of RPL includes metabolic/endocrinological abnormalities,genetic factors,anatomical factors,immune disorders,thrombophilia,male factors,and psychological factors.[1,2]Systemic autoimmune diseases like antiphospholipid syndrome(APS),[3]undifferentiated connective tissue disease(UCTD),[4]and systemic lupus erythematosus(SLE)[5]have been found to be important causes of RPL in recent years.Understanding the associations between different systemic autoimmune diseases and RPL,as well as being able to provide suitable diagnoses and treatments,is of great significance.Rui Gao Xun Zeng Lang Qin 2021Chinese Medical Journal2021,,17:2
10YWHAZ Binds to TRIM21 but Is Not Involved in TRIM21-stimulated Osteosarcoma Cell Proliferation显示文摘Objective Osteosarcoma is the most common type of malignant bone tumor in children and adolescents. The role of E3 ligases in tumorigenesis is currently a focus in tumor research. In the present study, we investigated the role of the E3 ligase tripartite motif 21(TRIM21) in osteosarcoma cell proliferation.Methods 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide(MTT) assays were used to assess osteosarcoma cell viability. U2-OS cells stably carrying a recombinant lentivirus expressing tetracycline-regulated TRIM21 were screened. Co-immunoprecipitation was coupled with LCMS/MS analysis to identify novel interacting partners of TRIM21. Co-immunoprecipitation and bimolecular fluorescence complementation(BIFC) were performed to validate the interactions between TRIM21 and its novel partner YWHAZ. A TRIM21-ΔRING construct was generated to test the effects of TRIM21 ligase activity on YWHAZ.Results TRIM21 positively regulated osteosarcoma cell proliferation. Overexpression of TRIM21 enhanced osteosarcoma cell tolerance toward various stresses. YWHAZ protein was identified as a novel interacting partner of TRIM21 and its expression levels were negatively regulated by TRIM21. The RING domain of TRIM21 was required for TRIM21 negative regulation of YWHAZ expression. However,overexpression of YWHAZ did not affect positive regulation of osteosarcoma cell proliferation by TRIM21.Conclusion Our results further clarify the molecular mechanisms underlying the pathogenesis of osteosarcoma.ZENG Qing Zhong LIU Wan Ting LU Jun Lei LIU Xiao Hui ZHANG Yun Fang LIU Lang Xia GAO Xue Juan 2018Biomedical and Environmental Sciences2018,31,3:2
11Surface‑Alloyed Nanoporous Zinc as Reversible and Stable Anodes for High‑Performance Aqueous Zinc‑Ion Battery显示文摘Metallic zinc(Zn)is one of the most attractive multivalent-metal anode materials in post-lithium batteries because of its high abundance,low cost and high theoretical capacity.However,it usually suffers from large voltage polarization,low Coulombic efficiency and high propensity for dendritic failure during Zn stripping/plating,hindering the practical application in aqueous rechargeable zinc-metal batteries(AR-ZMBs).Here we demonstrate that anionic surfactant-assisted in situ surface alloying of Cu and Zn remarkably improves Zn reversibility of 3D nanoporous Zn electrodes for potential use as high-performance AR-ZMB anode materials.As a result of the zincophilic ZnxCuy alloy shell guiding uniform Zn deposition with a zero nucleation overpotential and facilitating Zn stripping via the ZnxCuy/Zn galvanic couples,the self-supported nanoporous ZnxCuy/Zn electrodes exhibit superior dendrite-free Zn stripping/plating behaviors in ambient aqueous electrolyte,with ultralow polarizations under current densities up to 50 mA cm^(‒2),exceptional stability for 1900 h and high Zn utilization.This enables AR-ZMB full cells constructed with nanoporous ZnxCuy/Zn anode and K_(z)MnO_(2)cathode to achieve specific energy of as high as~430 Wh kg^(‒1)with~99.8%Coulombic efficiency,and retain~86%after long-term cycles for>700 h.Huan Meng Qing Ran Tian-Yi Dai Hang Shi Shu-Pei Zeng Yong-Fu Zhu Zi Wen Wei Zhang Xing-You Lang Wei-Tao Zheng Qing Jiang 2022Nano-Micro Letters2022,14,8:2

13Understanding the phase separation characteristics of nucleocapsid protein provides a new therapeutic opportunity against SARS-CoV-2显示文摘Dear Editor To date,tens of millions of people have been infected with severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),causing the outbreak of the respiratory disease named the coronavirus disease 2019(COVID-19).As a newly emerged member of the coronavirus family,SARS-CoV-2 is an enveloped positive-strand RNA virus,which has probably the largest genome(approximately 30 kb)among all RNA viruses.The nucleocapsid(N)protein of SARS-CoV-2 is mainly responsible for recognizing and wrapping viral RNA into helically symmetric structures(Malik,2020).Dan Zhao Weifan Xu Xiaofan Zhang Xiaoting Wang Yiyue Ge Enming Yuan Yuanpeng Xiong Shenyang Wu Shuya Li Nian Wu Tingzhong Tian Xiaolong Feng Hantao Shu Peng Lang Jingxin Li Fengcai Zhu Xiaokun Shen Haitao Li Pilong Li Jianyang Zeng 2021Protein & Cell2021,12,9:1
14One-pot pyrolysis synthesis of highly active Ru/RuOx nanoclusters for water splitting显示文摘Using simple methods to obtain efficient catalysts has been a long-standing goal for researchers.In this work,the employment of a one-pot pyrolysis reaction to achieve molecular confinement,has led to the preparation of ruthenium(Ru)-based nanoclusters in a carbon matrix.A unique feature of the synthetic approach employed is that solvent and substrates were calcined together.As solvent evaporates,during calcination,the substrates form a dense solid which has the effect of limiting the aggregation of Ru centers during the carbonization process.The catalyst prepared in this simple manner showed an impressively high activity with respect to the hydrogen/oxygen evolution reaction(HER/OER).The Ru nanoclusters(Ru NCs),as the hydrogen evolution reaction(HER)catalysts,require ultralow overpotentials of 5 mV and 5.1 mV at-10 mA·cm^(-2) in 1.0 M KOH,and 0.5 M H_(2)SO_(4),respectively.Furthermore,the catalyst prepared by the one-pot method has higher crystallinity,a higher Ru content and an ultrafine cluster size,which contributes to its exceptional electrochemical performance.Meanwhile,the RuO_(x) nanoclusters(RuO_(x) NCs),obtained by oxidizing the aforementioned Ru NCs,exhibited good oxygen evolution reaction(OER)performance with an overpotential of 266 mV at 10 mA·cm^(-2).When applied to overall water splitting,Ru/RuO_(x) nanoclusters as the cathode and anode catalysts can reach 10 mA·cm^(-2) at cell voltages of only 1.49 V in 1 M KOH.Fengyuan Zhu Jiangyan Xue Lingjian Zeng Jingrui Shang Shuanglong Lu Xueqin Cao Brendan F.Abrahams Hongwei Gu Jianping Lang 2022Nano Research2022,15,2:1
15Ultrahigh-energy and-power aqueous rechargeable zinc-ion microbatteries based on highly cation-compatible vanadium oxides显示文摘Aqueous multivalent-metal-ion intercalation chemistries hold genuine promise to develop safe and powerful microbatteries for potential use in many miniaturized electronics.However,their development is beset by state-of-the-art electrode materials having practical capacities far below their theoretical values.Here we demonstrate that high compatibility between layered transition-metal oxide hosts and hydrated cation guests substantially boost their multi-electron-redox reactions to offer higher capacities and rate capability,based on typical bipolar vanadium oxides preintercalated with hydrated cations(M_(x)V_(2)O_(5)).When seamlessly integrated on Au current microcollectors with a three-dimensional bicontinuous nanoporous architecture that offers high pathways of electron transfer and ion transport,the constituent Zn_(x)V_(2)O_(5) exhibits specific capacity of as high as∼527 mAh g^(−1) at 5 mV s^(−1) and retains∼300 mAh g^(−1) at 200 mV s^(−1) in 1 M ZnSO_(4) aqueous electrolyte,outperforming the M_(x)V_(2)O_(5)(M=Li,Na,K,Mg).This allows aqueous rechargeable zinc-ion microbatteries constructed with symmetric nanoporous Zn_(x)V_(2)O_(5)/Au interdigital microelectrodes as anode and cathode to show high-density energy of∼358 mWh cm^(−3)(a value that is forty-fold higher than that of 4 V/500μAh Li thin film battery)at high levels of power delivery.Sheng-Bo Wang Qing Ran Wu-Bin Wan Hang Shi Shu-Pei Zeng Zi Wen Xing-You Lang Qing Jiang 2022Journal of Materials Science & Technology2022,,25:1

18Programming of Regulatory T Cells In Situ for Nerve Regeneration and Long-Term Patency of Vascular Grafts显示文摘Rapid integration into the host tissue is critical for long-term patency after small diameter tissue engineering vascular grafts(sdTEVGs)transplantation.Neural recognition may be required for host integration and functionalization of the graft.However,immune rejection and inflammation hinder nerve regeneration of sdTEVGs.Here,a CRISPR/dCas9-nanocarrier was used for targeted programming of regulatory T cells(Treg cells)in situ to promote nerve regeneration of sdTEVGs by preventing excessive inflammation.Treg cells and(C-C chemokine receptor)CCR2+macrophage recruitment occurred after transplantation.The nanodelivery system upregulated ten eleven translocation(TET2)in Treg cells in vitro.Reprogrammed Treg cells upregulated anti-inflammatory cytokines and decreased the proportion of CCR2+macrophages.IL-6 concentrations decreased to the levels required for nerve regeneration.Implantation of CRISPR/dCas9 nanodelivery system-modified sdTEVGs in rats resulted in Treg cell editing,control of excessive inflammation,and promoted nerve regeneration.After 3 months,nerve regeneration was similar to that observed in normal blood vessels;good immune homeostasis,consistency of hemodynamics,and matrix regeneration were observed.Neural recognition promotes further integration of the graft into the host,with unobstructed blood vessels without intimal hyperplasia.Our findings provide new insights into vascular implant functionalization by the host.Yanhong Wang Fangchao Xue Yanzhao Li Lin Lin Yeqin Wang Shanlan Zhao Xingli Zhao Yong Liu Ju Tan Gang Li Haoran Xiao Juan Yan Hao Tian Min Liu Qiao Zhang Zhaojing Ba Lang He Wenyan Zhao Chuhong Zhu Wen Zeng 2022Research2022,,4:1
