1Radiofrequency 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 2018Journal of Interventional Medicine2018,1,1:9
2Cryo-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 2020Cell Research2020,30,7:2
3Room thermal load prediction based on analytic hierarchy process and back-propagation neural networks显示文摘Accurate prediction of the heat load is the basic premise of intelligent regulation of the heating system,which helps to realize effective management of heating,ventilation,air conditioning system.For the problem that the weight of each influencing factor is not taken into account in the current heat load prediction and is not highly targeted,this article deeply explores the influence of different factors on the room heat load,and we propose a method to calculate room heat load prediction based on the combination of analytic hierarchy process(AHP)and back-propagation(BP)neural network.Firstly,eight environmental factors affecting the heat load are selected as prediction inputs through parametric analysis,and then the weights of each input are determined by AHP and normalize the prediction data by combining expert opinions,and finally do one-to-one training the quantified score and the room heat load to predict the future heat load by BP neural network.The simulation tests show that the mean absolute relative error(MARE)of the proposed prediction method is 5.40%.This article also verifies the influence of different expert opinions on the stability of the model.The results show that the proposed method can guarantee higher prediction accuracy and stability.Xin Tan Zhenjing Zhu Guoxin Sun Linfeng Wu 2022Building Simulation2022,15,11:2
4Li4-xSbxSn1-xS4 solid solutions for air-stable solid electrolytes显示文摘The sulfide solid electrolytes have the characteristics of high ionic conductivity and low grain boundary resistance, which make them suitable for bulk-type all-solid-state batteries. However, most of them suffer from poor stability in air. Here, we explore the air stable sulfide solid electrolytes in Li4-xSbxSn1-xS4 system. The solid solutions of Li4-xSbxSn1-xS4(0 ≤ x ≤ 0.5) can be formed in Li4-xSbxSn1-xS4 system. Li3.8 Sb0.2 Sn0.8 S4 achieves the highest ionic conductivity of 3.5 × 10-4 S cm-1 in this system,which is 5 times as that of Li4 Sn S4 and 3 orders of magnitude higher than that of Li3 Sb S4, respectively. Li3.8 Sb0.2 Sn0.8 S4 crystallizes into the same structure with high ionic conductivity phase of β-Li3 PS4. Moreover, Li3.8 Sb0.2 Sn0.8 S4 owns good stability in humid air. Matching with LiCoO2 and Li4 Ti5 O12,Li3.8 Sb0.2 Sn0.8 S4 exhibits the potential to be applied in all-solid-state batteries.Zhuoran Zhang Jianxing Zhang Yulong Sun Huanhuan Jia Linfeng Peng Yunyang Zhang Jia Xie 2020Journal of Energy Chemistry2020,29,2:2
5Cryo-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 2019Cell Research2019,29,12:2

7Structures 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 2022Cell Research2022,32,5:1

11Magnetic resonance imaging characteristics of postoperative intracranial dissemination of recurrent gliomas显示文摘Ten intracranial gliomas cases, that had postoperative intracranial dissemination, underwent magnetic resonance imaging (MRI) examinations, including T1 weighted imaging, fat-suppressed T1 weighted imaging, T2 weighted imaging and fluid attenuated inversion recovery (FLAIR). Results showed that tumor metastasis had occurred via the cerebrospinal fluid, the brain white matter fibers and the surgical access site alone. On the plain MRI scans, 1/7 cases were linearly thickened with isointensity and 5/7 cases exhibited nodular foci on T1 weighted imaging; the cerebral sulci and cisterns in 2/7 cases had become shallow and five cases had nodular foci on T2 weighted imaging. FLAIR imaging revealed that the cerebral sulci and cisterns in 2/7 cases had become shallow and that six cases had affected nodular foci. The contrast-enhanced MRI scans revealed linear thickening in seven cases, nodules in seven cases, similarities to 'mould-like' signs in six cases and hydrocephalus in six cases. These findings suggested that MRI with different sequences can diagnose glioma metastasis.Linfeng Zheng Guixiang Zhang Jinglong Zhao Han Wang Kang'an Li Lin Zhang Xifu Wang Pengpeng Sun Yunsheng Hu 2011Neural Regeneration Research2011,6,33:1
12Classical and quantum phases in hexagonal boron nitride-combined van der Waals heterostructures显示文摘Since the discovery of graphene,two-dimensional(2D)layered materials have attracted extensive attention owing to their unique properties and promising potential applications.In particular,van der Waals(vdW)heterostructures,artificially stacked with 2D materials,have provided an excellent platform to explore various applications and to unveil long-standing mysteries in quantum and condensed matter physics.Here,we discuss recent progress in novel classical and quantum phases in vdW heterostructures,emerging through thickness-dependent hexagonal boron nitride(h-BN)combined with graphene and transitional metal dichalcogenides.As a cornerstone of vdW heterostructures,the h-BN plays diverse roles,such as tunneling barriers,dielectric layers,clean substrates,and capping layers,to realize numerous intriguing devices:field-effect transistors,tunneling light-emitting diodes,resonant tunneling diodes,nonvolatile memories,Bose-Einstein condensation,topological insulators,and graphene-based superconductors.The vdW heterostructures with various roles of h-BN continue to enrich our knowledge for quantum physics and practical future device applications.Shoujun Zheng Mali Zhao Linfeng Sun Heejun Yang 2021InfoMat2021,3,3:1

17Fuzzy cluster analysis of water mass in the western Taiwan Strait in spring 2019显示文摘The classification of the springtime water mass has an important influence on the hydrography,regional climate change and fishery in the Taiwan Strait.Based on 58 stations of CTD profiling data collected in the western and southwestern Taiwan Strait during the spring cruise of 2019,we analyze the spatial distributions of temperature(T)and salinity(S)in the investigation area.Then by using the fuzzy cluster method combined with the T-S similarity number,we classify the investigation area into 5 water masses:the Minzhe Coastal Water(MZCW),the Taiwan Strait Mixed Water(TSMW),the South China Sea Surface Water(SCSSW),the South China Sea Subsurface Water(SCSUW)and the Kuroshio Branch Water(KBW).The MZCW appears in the near surface layer along the western coast of Taiwan Strait,showing low-salinity(<32.0)tongues near the Minjiang River Estuary and the Xiamen Bay mouth.The TSMW covers most upper layer of the investigation area.The SCSSW is mainly distributed in the upper layer of the southwestern Taiwan Strait,beneath which is the SCSUW.The KBW is a high temperature(core value of 26.36℃)and high salinity(core value of 34.62)water mass located southeast of the Taiwan Bank and partially in the central Taiwan Strait.Zhiyuan Hu Jia Zhu Longqi Yang Zhenyu Sun Xin Guo Zhaozhang Chen Linfeng Huang 2023Acta Oceanologica Sinica2023,42,12:0
18Two-dimensional ferromagnetic superlattices显示文摘Mechanically exfoliated two-dimensional ferromagnetic materials(2D FMs)possess long-range ferromagnetic order and topologically nontrivial skyrmions in few layers.However,because of the dimensionality effect,such few-layer systems usually exhibitmuch lower Curie temperature(TC)compared to their bulk counterparts.It is therefore of great interest to explore effective approaches to enhance their TC,particularly in wafer-scale for practical applications.Here,we report an interfacial proximity-induced high-TC 2D FM Fe3GeTe2(FGT)via A-type antiferromagnetic material CrSb(CS)which strongly couples to FGT.A superlattice structure of(FGT/CS)n,where n stands for the period of FGT/CS heterostructure,has been successfully produced with sharp interfaces by molecular-beam epitaxy on 2-inch wafers.By performing elemental specific X-ray magnetic circular dichroism(XMCD)measurements,we have unequivocally discovered that TC of 4-layer Fe3GeTe2 can be significantly enhanced from 140 K to 230 K because of the interfacial ferromagnetic coupling.Meanwhile,an inverse proximity effect occurs in the FGT/CS interface,driving the interfacial antiferromagnetic CrSb into a ferrimagnetic state as evidenced by double-switching behavior in hysteresis loops and the XMCD spectra.Density functional theory calculations show that the Fe-Te/Cr-Sb interface is strongly FMcoupled and doping of the spin-polarized electrons by the interfacial Cr layer gives rise to the TC enhancement of the Fe3GeTe2 films,in accordance with our XMCDmeasurements.Strikingly,by introducing rich Fe in a 4-layer FGT/CS superlattice,TC can be further enhanced to near room temperature.Our results provide a feasible approach for enhancing the magnetic order of few-layer 2D FMs in wafer-scale and render opportunities for realizing realistic ultra-thin spintronic devices.Shanshan Liu Ke Yang Wenqing Liu Enze Zhang Zihan Li Xiaoqian Zhang Zhiming Liao Wen Zhang Jiabao Sun Yunkun Yang Han Gao Ce Huang Linfeng Ai Ping Kwan Johnny Wong Andrew Thye Shen Wee Alpha TN’Diaye Simon AMorton Xufeng Kou Jin Zou Yongbing Xu Hua Wu Faxian Xiu 2020National Science Review2020,7,4:0
19Image compression scheme based on PCA for wireless multimedia sensor networks显示文摘In combination of the characteristic of the network architecture of wireless multimedia sensor networks(WMSNs), a distributed multi-node cooperative network(DMCN) model is designed by using the concept of in-network processing to improve their energy, memory and computational power. To balance the energy consumption of the network, according to roles division, camera nodes and common nodes are cooperated to accomplish the workload of image acquisition, compression and transmission. Camera nodes gather images and send blocking images to the common nodes in cluster. Common nodes adaptively compress the partitioned images by using a noise-tolerant distributed image compression(NDIC) algorithm based on principal component analysis(PCA) called NDIC-PCA algorithm and send the compressed data to the cluster head node. Then, the cluster head node sends the compressed image data to the station. Simulation results demonstrate that, DCNM can effectively balance the energy consumption of network and largely extend the network lifecycle. In addition, compared with previous algorithms, the proposed NDIC-PCA algorithm achieves higher peak signal to noise ratio without decreasing compression ratio.Zhou Wei Sun Lijuan Guo Jian Liu Linfeng 2016The Journal of China Universities of Posts and Telecommunications2016,23,1:0
