| 1 | Radiofrequency ablation combined with transcatheter arterial chemoembolization therapy versus surgical resection for Barcelona-Clinic Liver Cancer(BCLC) A hepatocellular carcinoma: a meta-analysis显示文摘Purpose: The objective of our study was to compare the effectiveness of the combination of transcatheter arterial chemoembolization(TACE) and radiofrequency ablation(RFA) with that of surgical resection(SR) in Barcelona-Clinic Liver Cancer(BCLC) A hepatocellular carcinoma. Materials and Methods: PubMed, Medline, Embase, and Cochrane Library were searched for comparisons of the two therapies from January 2006 to December 2017. Overall survival rate(OS), recurrence-free survival rate(RFS), complications, and the average length of hospital stay were compared and analyzed. Review Manager v. 5.2 from the Cochrane Collaboration was used for statistical analyses. Results: Seven case-control studies and one randomized controlled trial were identified, of which 717 were treated with a combination of TACE and RFA and 785 were treated with SR. Meta-analysis data revealed that TACE plus RFA had significantly better effectiveness on 1.0-y OS(OR = 0.50, p =.009). The major complications(ORcomplications = 1.88, p =.02) after the combined therapy were significantly lower than those after SR. There were three studies that reported the average length of hospital stay. The hospital stay for the SR group vs the combined therapy group was 19.8 ± 8.4 d vs 7.4 ± 2.2 d, respectively(p <.0001); 18.7 ± 4.9 d vs 11.5 ± 6.9 d, respectively(p <.0001); and 16.6 ± 6.7 d vs 8.5 ± 4.1 d, respectively(p <.0001). There was no significant difference in 3.0-or 5.0-y OS and 1.0-, 3.0-, or 5.0-y RFS. Conclusion: The combination of TACE and RFA has advantages in improving 1.0-y OS, reducing complications, and shortening the length of hospital stay over that of SR in the treatment of patients with BCLC A HCC. | Weidong Wang Sinan Hou Zelong Zhong JiaYan Ni Xiongying Jiang Dong Chen Yaoting Chen Jianghong Luo Hongliang Sun Linfeng Xu | 2018 | Journal of Interventional Medicine2018，1，1： | 9 |
| 2 | Internal structures and high-velocity frictional properties of Longmenshan fault zone at Shenxigou activated during the 2008 Wenchuan earthquake显示文摘This paper reports internal structures of a wide fault zone at Shenxigou,Dujiangyan,Sichuan province,China,and high-velocity frictional properties of the fault gouge collected near the coseismic slip zone during the 2008 Wenchuan earthquake.Vertical offset and horizontal displacement at the trench site were 2.8 m(NW side up)and 4.8 m(right-lateral),respectively.The fault zone formed in Triassic sandstone,siltstone,and shale about 500 m away from the Yingxiu-Beichuan fault,a major fault in the Longmenshan fault system.A trench survey across the coseismic fault,and observations of outcrops and drill cores down to a depth of 57 m revealed that the fault zone consists of fault gouge and fault breccia of about0.5 and 250–300 m in widths,respectively,and that the fault strikes N62°E and dips 68° to NW.Quaternary conglomerates were recovered beneath the fault in the drilling,so that the fault moved at least 55 m along the coseismic slip zone,experiencing about 18 events of similar sizes.The fault core is composed of grayish gouge(GG) and blackish gouge(BG) with very complex slip-zone structures.BG contains low-crystalline graphite of about 30 %.High-velocity friction experiments were conducted at normal stresses of 0.6–2.1 MPa and slip rates of 0.1–2.1 m/s.Both GG and BG exhibit dramatic slip weakening at constant high slip rates that can be described as an exponential decay from peak friction coefficient lpto steadystate friction coefficient lssover a slip-weakening distance Dc.Deformation of GG and BG is characterized by overlapped slip-zone structures and development of sharp slickenside surfaces,respectively.Comparison of our data with those reported for other outcrops indicates that the high-velocity frictional properties of the Longmenshan fault zones are quite uniform and the high-velocity weakening must have promoted dynamic rupture propagation during the Wenchuan earthquake. | Yu Wang Shengli Ma Toshihiko Shimamoto Lu Yao Jianye Chen Xiaosong Yang Honglin He Jiaxiang Dang Linfeng Hou Tetsuhiro Togo | 2014 | Earthquake Science2014，27，5： | 3 |
| 3 | Cryo-EM structure of human bile salts exporter ABCB11显示文摘Dear Editor,Bile is a complex aqueous secretion produced by the liver that facilitates the digestion of lipids in the small intestine.A group of ATP binding cassette(ABC)transporters localizing at the apical canalicular domain of hepatocytes are responsible for the secretion of the bile organic solutes to the bile canaliculi,1 including organic anions,cholesterol,bile salts,glutathione,organic cations and phospholipid(Fig.1a).To date,the 3-D structures of ABCG2,ABCG5/G8,ABCB1,ABCB4 have been reported,2'3 leaving the structures of ABCB11 and ABCC2 unknown,despite we can get some information from the homologous structures of ABCC1,4 ABCB1 and ABCB4. | Liang Wang Wen-Tao Hou Li Chen Yong-Liang Jiang Da Xu Linfeng Sun Cong-Zhao Zhou&Yuxing Chen | 2020 | Cell Research2020，30，7： | 2 |
| 4 | Designing heterostructured FeP–CoP for oxygen evolution reaction:Interface engineering to enhance electrocatalytic performance显示文摘It is significant to develop highly efficient electrocatalysts for energy conversion systems.Interface engineering is one of the most feasible approaches to effectively enhance the electrocatalytic activity.Herein,the density functional theory(DFT)calculations predict that the potential barriers of Fe sites at the interface of FeP–CoP heterostructures are lower than that of Fe sites in FeP nanoparticles(NPs),Co sites in CoP NPs,or Co sites in heterostructures.Motivated by the DFT calculation results,FeP–CoP heterostructures have been designed and synthesized by a metal–organic frameworks(MOFs)confined-phosphorization method.The FeP–CoP exhibits the lowest overpotential of 230 mV at the current density of 10 mA·cm^(−2)for oxygen evolution reaction(OER),compared with FeP(470 mV)and CoP(340 mV),which outperforms most of transition metal-based catalysts.The Tafel analysis of FeP–CoP heterostructures shows an improved reaction kinetic pathway with the smallest slope of 90.3 mV·dec^(−1),as compared to the Tafel slopes of FeP NPs(137 mV·dec^(−1))and CoP NPs(114 mV·dec^(−1)).And the FeP–CoP shows extraordinary long-term stability over 24 h.The excellent activity and long-term stability of FeP–CoP derive from the synergistic effect between FeP and CoP. | Shuang Hou Ansai Zhang Qi Zhou Yingjie Wen Sixie Zhang Linfeng Su Xinjie Huang Tian Wang Kun Rui Cheng Wang Huiling Liu Zhiyi Lu Peilei He | 2023 | Nano Research2023，16，5： | 2 |
| 5 | Cryo-EM structure of human lysosomal cobalamin exporter ABCD4显示文摘Dear Editor,Cobalamin,also known as vitamin B12,can only be biosynthesized by certain bacteria and archaea.As an essential nutrient for humans,it should be obtained from daily food.1 Exogenous cobalamin is taken up by the cell through an endocytosis process,then released into the lysosome as a free form,and finally pumped out to the cytosol for utilization.2 The human ATP-binding cassette(ABC)transporter ABCD4 localized on lysosomal membrane is indispensable for the efflux of cobalamin from lysosome to cytosol.3 Mutations in ABCD4 gene may result in cobalamin deficiency and inborn diseases.The patients suffer from combined symptoms:hypotonia,lethargy,poor feeding,bone marrow suppression,macrocytic anemia,and heart defects.3 However,the absence of the structure of human ABCD4 limits our understanding of the molecular mechanism of pathogenesis. | Da Xu Zhang Feng Wen-Tao Hou Yong-Liang Jiang Liang Wang Linfeng Sun Cong-Zhao Zhou Yuxing Chen | 2019 | Cell Research2019，29，12： | 2 |
| 6 | Structures of human bile acid exporter ABCB11 reveal a transport mechanism facilitated by two tandem substrate-binding pockets显示文摘Dear Editor,Bile acids are a group of cholesterol-derived physiological surfactants required for digestion of lipids and fat-soluble vitamins.1However,excess of bile acids is detrimental to metabolic homeostasis and bile acid imbalance can contribute to cancer progression.2Bile acids are produced primarily in the liver and then secreted to the bile duct before delivery to the small intestine,where up to 95%of bile acids are reabsorbed and recirculated to the liver(Supplementary information,Fig.S1a).The primary bile acids are biosynthesized in hepatocytes via oxidation of cholesterol and modified by either taurine or glycine,forming the conjugated primary bile acids which harbor a cholic acid moiety and a taurine/glycine moiety(Supplementary information,Fig.S1 b).This enterohepatic circulation of bile acids is driven by a series of transmembrane transporters(Supplementary informa-tion,Fig.S1a),including the ATP-binding cassette(ABC)transpor-ter ABCB11(also termed bile salt export pump BSEP). | Liang Wang Wen-Tao Hou Jie Wang Da Xu Cong Guo Linfeng Sun Ke Ruan Cong-Zhao Zhou Yuxing Chen | 2022 | Cell Research2022，32，5： | 1 |
| 7 | Effect of 5%glycolic acid complex and 20%glycolic acid on mild-to-moderate facial acne vulgaris显示文摘To the Editor:Acne vulgaris is a chronic,inflammatory,and disfiguring skin disease with lesions,post-inflammatory hyperpigmentation,and scarring.Chemical peeling is a simple and well-tolerated procedure for mild-to-moderate acne.Glycolic acid(GA)is water-soluble and has the smallest molecular weight among all the alpha-hydroxy acids.High-concentration GA(20%–70%),applied at 2 to 4-week intervals in the hospital or cosmetology clinic,have proved effective for acne.[1]Low-concentration GA(10%)is safe and convenient,and can be used at home.[2]Up to now,differences in efficiency between low and high concentrations of GA for acne vulgaris have not been reported.This study compared the efficacy and safety of 5%GA complex and 20%GA for acne patients,to guide GA selection at different concentrations. | Jian Zhao Boyang Zhou Yan Hou Linfeng Li Fenglin Zhuo | 2022 | Chinese Medical Journal2022，135，21： | 0 |
| 8 | Enabling ultranarrow blue emission linewidths in colloidal alloy quantum dots by decreasing the exciton fine structure splitting and exciton–phonon coupling显示文摘The realization of colloidal alloy quantum dots(QDs)with narrow spectral linewidths requires minimization of the contributions of inhomogeneous and homogeneous broadening to the ensemble spectrum.Recently,there has been remarkable progress in eliminating the inhomogeneous contribution by controlling the size distribution of the QDs.However,considerable challenges remain in suppressing the homogeneous broadening,in terms of both intrinsic principles and rational synthetic routes.We find that ground-state exciton fine structure splitting and exciton-phonon coupling play a pivotal role in the homogeneous broadening mechanism.Here we demonstrate that the elimination of the lattice mismatch strain by using a coherent strain structure can decrease the light-heavy hole splitting,thus suppressing the asymmetric broadening of the emission on the high energy side.Besides,the improvement of the uniformity of the alloy by using a stepwise ion exchange strategy can weaken the exciton-longitudinal optical(LO)-phonon interactions,further minimizing the homogeneous broadening.As a result,the final alloy QD products exhibit a widely tunable blue emission wavelength(445-470 nm)with the narrowest ensemble photoluminescence full width at half maximum(FWHM)of 10.1-13.5 nm(or 58.4-75.3 meV).Our study provides a potential strategy for other semiconductor nanocrystals with ultranarrow spectral linewidths. | Jinke Bai Linfeng Wang Tingting Zhang Tianyi Hou Meilun Zhang Bing Xu Dongyu Li Xiao Jin Qinghua Li Yuxiao Wang Xueru Zhang Yinglin Song | 2023 | Nano Research2023，16，1： | 0 |
| 9 | RIPK3 promotes hantaviral replication by restricting JAK-STAT signaling without triggering necroptosis显示文摘Hantaan virus(HTNV)is a rodent-borne virus that causes hemorrhagic fever with renal syndrome(HFRS),resulting in a high mortality rate of 15%.Interferons(IFNs)play a critical role in the anti-hantaviral immune response,and IFN pretreatment efficiently restricts HTNV infection by triggering the expression of a series of IFNstimulated genes(ISGs)through the Janus kinase-signal transducer and activator of transcription 1(JAK-STAT)pathway.However,the tremendous amount of IFNs produced during late infection could not restrain HTNV replication,and the mechanism remains unclear.Here,we demonstrated that receptor-interacting protein kinase 3(RIPK3),a crucial molecule that mediates necroptosis,was activated by HTNV and contributed to hantavirus evasion of IFN responses by inhibiting STAT1 phosphorylation.RNA-seq analysis revealed the upregulation of multiple cell death-related genes after HTNV infection,with RIPK3 identified as a key modulator of viral replication.RIPK3 ablation significantly enhanced ISGs expression and restrained HTNV replication,without affecting the expression of pattern recognition receptors(PRRs)or the production of type I IFNs.Conversely,exogenously expressed RIPK3 compromised the host's antiviral response and facilitated HTNV replication.RIPK3^(-/-)mice also maintained a robust ability to clear HTNV with enhanced innate immune responses.Mechanistically,we found that RIPK3 could bind STAT1 and inhibit STAT1 phosphorylation dependent on the protein kinase domain(PKD)of RIPK3 but not its kinase activity.Overall,these observations demonstrated a noncanonical function of RIPK3 during viral infection and have elucidated a novel host innate immunity evasion strategy utilized by HTNV. | Yue Si Haijun Zhang Ziqing Zhou Xudong Zhu Yongheng Yang He Liu Liang Zhang Linfeng Cheng Kerong Wang Wei Ye Xin Lv Xijing Zhang Wugang Hou Gang Zhao Yingfeng Lei Fanglin Zhang Hongwei Ma | 2023 | Virologica Sinica2023，38，5： | 0 |
| 10 | The Paleozoic Huoshenmiao iron skarn deposit in the Tongbai area of North Qinling Orogen,China:Insights from garnet U-Pb dating and geological constraints显示文摘The Qinling Orogen is a composite orogenic belt that can be subdivided into the North and South Qinling,broadly separated by the Shangdan suture zone.These two orogenic belts were generated by subduction-collisional processes in the Early Paleozoic and Late Triassic,respectively.During the Late Jurassic to Early Cretaceous,the eastern portion of the Qinling Orogen was tectonically reactivated due to westerly subduction of the Izanagi plate underneath the East China continental margin.The Qinling Orogen is well-endowed with numerous Au,Mo,Ag-Pb-Zn deposits that predominantly formed in the Late Triassic to Early Cretaceous,with rare Paleozoic varieties documented.In this study,we present garnet and zircon U-Pb dating results to show that the Huoshenmiao iron skarn deposit in the Tongbai area of North Qinling orogenic belt formed in the Early Silurian and is genetically related to subduction-related magmatism.The Huoshenmiao deposit consists of lenticular and stratiform orebodies that contain massive or densely disseminated magnetite variably associated with garnet,diopside,epidote,hornblende,and actinolite.Garnets from iron ores are andradite and grossular in composition(Ad_(83.1)Gr_(13.3)-Ad_(86.5)Gr_(10.2))and characterized by enrichment in light rare earth elements(ΣLREE=57.85-103.82 ppm)and depletion in heavy rare earth elements(ΣHREE=5.50-11.34 ppm),with significantly positive Eu and Ce anomalies(δEu of 1.09-1.89 andδCe of 1.39-1.69).These compositional signatures are distinctly different from those of garnets in the ore-hosting metamorphic rocks that are typically dominated by almandine,spessartine and grossular(Al_(47.4)Sp_(30.4)Gr_(13.8)-Al_(51.9)Sp_(24.8)Gr_(17.6)),depleted in LREE(0.14-0.69 ppm),enriched in HREE(95.68-841.60 ppm)and have pronounced negative Eu anomalies(δEu=0.24-0.51).In addition,garnets from iron ores of the Huoshenmiao deposit contain abundant daughter mineral-bearing,multiphase fluid inclusions,further confirming their hydrothermal origin.Two samples of those hydrothermal garnets yield U-Pb dates of 437±9 Ma and 437±10 Ma(2σ),revealing a Paleozoic mineralization event that has long been ignored and rarely documented.These garnet dates agree well with zircon U-Pb dates of 438±4 Ma to 436±3 Ma for a gabbroic diorite and 430±4 Ma for a granite intrusion in close proximity of the mine,supporting a possible genetic link between the iron mineralization and Early Silurian magmatism.The Paleozoic intrusions are enriched in large ion lithophile elements(LILEs:Ba,K,Sr)and LREEs,depleted in high field strength elements(HFSEs:Nb,Ta,P,Ti),have whole-rock(^(87)Sr/^(86)Sr)i,ε_(Nd)(t),and zirconεHf(t)values of 0.7039-0.7042,3.32-4.33,and 13.0-14.9,respectively.These geochemical and isotopic characteristics suggest that the Paleozoic intrusions were affiliated with arc magmatism triggered by subduction of the Shangdan oceanic plate in the Early Paleozoic.Recognition of the Silurian Huoshenmiao iron skarn deposit opens a new window for exploration of Paleozoic mineral resources in the Tongbai area and other portions of the North Qinling Orogen. | Mingchun CHAI Hao HU Jianwei LI Shiguang DU Linfeng HOU | 2021 | Science China Earth Sciences2021，64，12： | 0 |
