3Synergistic effect of fluorination on both donor and acceptor materials for high performance non-fullerene polymer solar cells with 13.5% efficiency显示文摘A high performance polymer solar cells(PSCs) based on polymer donor PM6 containing fluorinated thienyl benzodithiophene unit and n-type organic semiconductor acceptor IT-4 F containing fluorinated end-groups were developed. In addition to complementary absorption spectra(300–830 nm) with IT-4 F, the PM6 also has a deep HOMO(the highest occupied molecular) level(-5.50 e V), which will lower the open-circuit voltage(V_(oc)) sacrifice and reduce the E_(loss) of the IT-4 F-based PSCs. Moreover, the strong crystallinity of PM6 is beneficial to form favorable blend morphology and hence to suppress recombination. As a result, in comparison with the PSCs based on a non-fluorinated D/A pair of PBDB-T:ITIC with a medium PCE of 11.2%, the PM6:IT-4 Fbased PSCs yielded an impressive PCE of 13.5% due to the synergistic effect of fluorination on both donor and acceptor, which is among the highest values recorded in the literatures for PSCs to date. Furthermore, a PCE of 12.2% was remained with the active layer thickness of up to 285 nm and a high PCE of 11.4% was also obtained with a large device area of 1 cm^2. In addition, the devices also showed good storage, thermal and illumination stabilities with respect to the efficiency. These results indicate that fluorination is an effective strategy to improve the photovoltaic performance of materials, as well as the both fluorinated donor and acceptor pair-PM6:IT-4 F is an ideal candidate for the large scale roll-to-roll production of efficient PSCs in the future.Qunping Fan Wenyan Su Yan Wang Bing Guo Yufeng Jiang Xia Guo Feng Liu Thomas P.Russell Maojie Zhang Yongfang Li 2018Science China Chemistry2018,61,5:18
4Multichannel vectorial holographic display and encryption显示文摘Since its invention,holography has emerged as a powerful tool to fully reconstruct the wavefronts of light including all the fundamental properties(amplitude,phase,polarization,wave vector,and frequency).For exploring the full capability for information storage/display and enhancing the encryption security of metasurface holograms,smart multiplexing techniques together with suitable metasurface designs are highly demanded.Here,we integrate multiple polarization manipulation channels for various spatial phase profiles into a single birefringent vectorial hologram by completely avoiding unwanted cross-talk.Multiple independent target phase profiles with quantified phase relations that can process significantly different information in different polarization states are realized within a single metasurface.For our metasurface holograms,we demonstrate high fidelity,large efficiency,broadband operation,and a total of twelve polarization channels.Such multichannel polarization multiplexing can be used for dynamic vectorial holographic display and can provide triple protection for optical security.The concept is appealing for applications of arbitrary spin to angular momentum conversion and various phase modulation/beam shaping elements.Ruizhe Zhao Basudeb Sain Qunshuo Wei Chengchun Tang Xiaowei Li Thomas Weiss Lingling Huang Yongtian Wang Thomas Zentgraf 2018Light(Science & Applications)2018,7,1:15
5Magnetic resonance elastography is accurate in detecting advanced fibrosis in autoimmune hepatitis显示文摘To assess the value of magnetic resonance elastography(MRE) in detecting advanced fibrosis/cirrhosis in autoimmune hepatitis(AIH).METHODS In this retrospective study, 36 patients(19 treated and 17 untreated) with histologically confirmed AIH and liver biopsy performed within 3 mo of MRE were identified at a tertiary care referral center. Liver stiffness(LS) with MRE was calculated by a radiologist, and inflammation grade and fibrosis stage in liver biopsy was assessed by a pathologist in a blinded fashion. Two radiologistsevaluated morphological features of cirrhosis on conventional magnetic resonance imaging(MRI). Accuracy of MRE was compared to laboratory markers and MRI for detection of advanced fibrosis/cirrhosis.RESULTS Liver fibrosis stages of 0, 1, 2, 3 and 4 were present in 4, 6, 7, 6 and 13 patients respectively. There were no significant differences in distribution of fibrosis stage and inflammation grade between treated and untreated patient groups. LS with MRE demonstrated stronger correlation with liver fibrosis stage in comparison to laboratory markers for chronic liver disease(r = 0.88 vs-0.48-0.70). A trend of decreased mean LS in treated patients compared to untreated patients was observed(3.7 k Pa vs 3.84 k Pa) but was not statistically significant. MRE had an accuracy/sensitivity/specificity/positive predictive value/negative predictive value of 0.97/90%/100%/100%/90% and 0.98/92.3%/96%/92.3%/96% for detection of advanced fibrosis and cirrhosis, respectively. The performance of MRE was significantly better than laboratory tests for detection of advanced fibrosis(0.97 vs 0.53-0.80, P < 0.01), and cirrhosis(0.98 vs 0.58-0.80, P < 0.01) and better than conventional MRI for diagnosis of cirrhosis(0.98 vs 0.78, P = 0.002).CONCLUSION MRE is a promising modality for detection of advanced fibrosis and cirrhosis in patients with AIH with superior diagnostic accuracy compared to laboratory assessment and MRI.Jin Wang Neera Malik Meng Yin Thomas C Smyrk Albert J Czaja Richard L Ehman Sudhakar K Venkatesh 2017World Journal of Gastroenterology2017,23,5:15

7Retrospective study on mixed neuroendocrine non-neuroendocrine neoplasms from five European centres显示文摘BACKGROUND Mixed neuroendocrine non-neuroendocrine neoplasm(MiNEN)is a rare diagnosis,mainly encountered in the gastro-entero-pancreatic tract.There is limited knowledge of its epidemiology,prognosis and biology,and the best management for affected patients is still to be defined.AIM To investigate clinical-pathological characteristics,treatment modalities and survival outcomes of a retrospective cohort of patients with a diagnosis of MiNEN.METHODS Consecutive patients with a histologically proven diagnosis of MiNEN were identified at 5 European centres.Patient data were retrospectively collected from medical records.Pathological samples were reviewed to ascertain compliance with the 2017 World Health Organisation definition of MiNEN.Tumour responses to systemic treatment were assessed according to the Response Evaluation Criteria in Solid Tumours 1.1.Kaplan-Meier analysis was applied to estimate survival outcomes.Associations between clinical-pathological characteristics and survival outcomes were explored using Log-rank test for equality of survivors functions(univariate)and Cox-regression analysis(multivariable).RESULTS Sixty-nine consecutive patients identified;Median age at diagnosis:64 years.Males:63.8%.Localised disease(curable):53.6%.Commonest sites of origin:colon-rectum(43.5%)and oesophagus/oesophagogastric junction(15.9%).The neuroendocrine component was;predominant in 58.6%,poorly differentiated in 86.3%,and large cell in 81.25%,of cases analysed.Most distant metastases analysed(73.4%)were occupied only by a poorly differentiated neuroendocrine component.Ninety-four percent of patients with localised disease underwent curative surgery;53%also received perioperative treatment,most often in line with protocols for adenocarcinomas from the same sites of origin.Chemotherapy was offered to most patients(68.1%)with advanced disease,and followed protocols for pure neuroendocrine carcinomas or adenocarcinomas in equal proportion.In localised cases,median recurrence free survival(RFS);14.0 months(95%CI:9.2-24.4),and median overall survival(OS):28.6 months(95%CI:18.3-41.1).On univariate analysis,receipt of perioperative treatment(vs surgery alone)did not improve RFS(P=0.375),or OS(P=0.240).In advanced cases,median progression free survival(PFS);5.6 months(95%CI:4.4-7.4),and median OS;9.0 months(95%CI:5.2-13.4).On univariate analysis,receipt of palliative active treatment(vs best supportive care)prolonged PFS and OS(both,P<0.001).CONCLUSION MiNEN is most commonly driven by a poorly differentiated neuroendocrine component,and has poor prognosis.Advances in its biological understanding are needed to identify effective treatments and improve patient outcomes.Melissa Frizziero Xin Wang Bipasha Chakrabarty Alexa Childs Tu V Luong Thomas Walter Mohid S Khan Meleri Morgan Adam Christian Mona Elshafie Tahir Shah Annamaria Minicozzi Wasat Mansoor Tim Meyer Angela Lamarca Richard A Hubner Juan W Valle Mairéad G McNamara 2019World Journal of Gastroenterology2019,25,39:13
8Boceprevir,GC-376,and calpain inhibitors Ⅱ,Ⅻ inhibit SARS-CoV-2 viral replication by targeting the viral main protease显示文摘A new coronavirus SARS-CoV-2,also called novel coronavirus 2019(2019-nCoV),started to circulate among humans around December 2019,and it is now widespread as a global pandemic.The disease caused by SARS-CoV-2 virus is called COVID-19,which is highly contagious and has an overall mortality rate of 6.35%as of May 26,2020.There is no vaccine or antiviral available for SARS-CoV-2.In this study,we report our discovery of inhibitors targeting the SARS-CoV-2 main protease(Mpro).Using the FRET-based enzymatic assay,several inhibitors including boceprevir,GC-376,and calpain inhibitorsⅡ,andⅫwere identified to have potent activity with single-digit to submicromolar ICs0 values in the enzymatic assay.The mechanism of action of the hits was further characterized using enzyme kinetic studies,thermal shift binding assays,and native mass spectrometry.Significantly,four compounds(boceprevir,GC-376,calpain inhibitorsⅡandⅫ)inhibit SARS-CoV-2 viral replication in cell culture with EC50 values ranging from 0.49 to 3.37μM.Notably,boceprevir,calpain inhibitorsⅡandⅫrepresent novel chemotypes that are distinct from known substrate-based peptidomimetic Mpro inhibitors.A complex crystal structure of SARS-CoV-2 Mpro with GC-376,determined at 2.15(A)resolution with three protomers per asymmetric unit,revealed two unique binding configurations,shedding light on the molecular interactions and protein conformational flexibility underlying substrate and inhibitor binding by Mpro.Overall,the compounds identified herein provide promising starting points for the further development of SARS-CoV-2 therapeutics.Chunlong Ma Michael Dominic Sacco Brett Hurst Julia Alma Townsend Yanmei Hu Tommy Szeto Xiujun Zhang Bart Tarbet Michael Thomas Marty Yu Chen Jun Wang 2020Cell Research2020,30,8:13

11Affinity peptide developed by phage display selection for targeting gastric cancer显示文摘AIM:To develop an affinity peptide that binds to gastric cancer used for the detection of early gastric cancer.METHODS:A peptide screen was performed by biopanning the PhD-12 phage display library,clearing non-specific binders against tumor-adjacent normal appearing gastric mucosa and obtaining selective binding against freshly harvested gastric cancer tissues.Tumortargeted binding of selected peptides was confirmed by bound phage counts,enzyme-linked immunosorbent assay,competitive inhibition,fluorescence microscopy and semi-quantitative analysis on immunohistochemistry using different types of cancer tissues.RESULTS:Approximately 92.8% of the non-specific phage clones were subtracted from the original phage library after two rounds of biopanning against normal-appearing gastric mucosa.After the third round of positive screening,the peptide sequence AADNAKTKSFPV(AAD) appeared in 25%(12/48) of the analyzed phages.For the control peptide,these values were 6.8 ± 2.3,5.1 ± 1.7,3.5 ± 2.1,4.6 ± 1.9 and 1.1 ± 0.5,respectively.The values for AAD peptide were statistically signif icant(P < 0.01) for gastric cancer as compared with other histological classif ications and control peptide.CONCLUSION:A novel peptide is discovered to have a specific binding activity to gastric cancer,and can be used to distinguish neoplastic from normal gastric mucosa,demonstrating the potential for early cancer detection on endoscopy.Wen-Jie Zhang Yan-Xia Sui Arun Budha Jian-Bao Zheng Xue-Jun Sun Ying-Chun Hou Thomas D Wang Shao-Ying Lu 2012World Journal of Gastroenterology2012,18,17:12
12The enhanced X-ray Timing and Polarimetry mission—eXTP显示文摘In this paper we present the enhanced X-ray Timing and Polarimetry mission—eXTP. eXTP is a space science mission designed to study fundamental physics under extreme conditions of density, gravity and magnetism. The mission aims at determining the equation of state of matter at supra-nuclear density, measuring effects of QED, and understanding the dynamics of matter in strong-field gravity. In addition to investigating fundamental physics, eXTP will be a very powerful observatory for astrophysics that will provide observations of unprecedented quality on a variety of galactic and extragalactic objects. In particular, its wide field monitoring capabilities will be highly instrumental to detect the electro-magnetic counterparts of gravitational wave sources.The paper provides a detailed description of:(1) the technological and technical aspects, and the expected performance of the instruments of the scientific payload;(2) the elements and functions of the mission, from the spacecraft to the ground segment.ShuangNan Zhang Andrea Santangelo Marco Feroci YuPeng Xu FangJun Lu Yong Chen Hua Feng Shu Zhang Sφren Brandt Margarita Hernanz Luca Baldini Enrico Bozzo Riccardo Campana Alessandra De Rosa YongWei Dong Yuri Evangelista Vladimir Karas Norbert Meidinger Aline Meuris Kirpal Nandra Teng Pan Giovanni Pareschi Piotr Orleanski QiuShi Huang Stephane Schanne Giorgia Sironi Daniele Spiga Jiri Svoboda Gianpiero Tagliaferri Christoph Tenzer Andrea Vacchi Silvia Zane Dave Walton ZhanShan Wang Berend Winter Xin Wu Jean J.M.in't Zand Mahdi Ahangarianabhari Giovanni Ambrosi Filippo Ambrosino Marco Barbera Stefano Basso Jörg Bayer Ronaldo Bellazzini Pierluigi Bellutti Bruna Bertucci Giuseppe Bertuccio Giacomo Borghi XueLei Cao Franck Cadoux Francesco Ceraudo TianXiang Chen Yu Peng Chen Jerome Chevenez Marta Civitani Wei Cui WeiWei Cui Thomas Dauser Ettore Del Monte Sergio Di Cosimo Sebastian Diebold Victor Doroshenko Michal Dovciak YuanYuan Du Lorenzo Ducci QingMei Fan Yannick Favre Fabio Fuschino JoséLuis Ga'lvez Min Gao MingYu Ge Olivier Gevin Marco Grassi QuanYing Gu YuDong Gu DaWei Han Bin Hong Wei Hu Long Ji ShuMei Jia WeiChun Jiang Thomas Kennedy Ingo Kreykenbohm Irfan Kuvvetli Claudio Labanti Luca Latronico Gang Li MaoShun Li Xian Li Wei Li ZhengWei Li Olivier Limousin HongWei Liu XiaoJing Liu Bo Lu Tao Luo Daniele Macera Piero Malcovati Adrian Martindale Malgorzata Michalska Bin Meng Massimo Minuti Alfredo Morbidini Fabio Muleri Stephane Paltani Emanuele Perinati Antonino Picciotto Claudio Piemonte JinLu Qu Alexandre Rachevski Irina Rashevskaya Jerome Rodriguez Thomas Schanz ZhengXiang Shen LiZhi Sheng JiangBo Song LiMing Song Carmelo Sgro Liang Sun Ying Tan Phil Uttley Bo Wang DianLong Wang GuoFeng Wang Juan Wang LangPing Wang YuSa Wang Anna L.Watts XiangYang Wen Jörn Wilms ShaoLin Xiong JiaWei Yang Sheng Yang YanJi Yang Nian Yu WenDa Zhang Gianluigi Zampa Nicola Zampa Andrzej A.Zdziarski AiMei Zhang ChengMo Zhang Fan Zhang Long Zhang Tong Zhang Yi Zhang XiaoLi Zhang ZiLiang Zhang BaoSheng Zhao ShiJie Zheng Yu Peng Zhou Nicola Zorzi J.Frans Zwart 2019Science China(Physics,Mechanics & Astronomy)2019,62,2:11
13Deep-learning based denoising and reconstruction of super-resolution structured illumination microscopy images显示文摘Super-resolution structured illumination microscopy(SR-SIM) provides an up to twofold enhanced spatial resolution of fluorescently labeled samples. The reconstruction of high-quality SR-SIM images critically depends on patterned illumination with high modulation contrast. Noisy raw image data(e.g., as a result of low excitation power or low exposure time), result in reconstruction artifacts. Here, we demonstrate deep-learning based SR-SIM image denoising that results in high-quality reconstructed images. A residual encoding–decoding convolutional neural network(RED-Net) was used to successfully denoise computationally reconstructed noisy SR-SIM images.We also demonstrate the end-to-end deep-learning based denoising and reconstruction of raw SIM images into high-resolution SR-SIM images. Both image reconstruction methods prove to be very robust against image reconstruction artifacts and generalize very well across various noise levels. The combination of computational image reconstruction and subsequent denoising via RED-Net shows very robust performance during inference after training even if the microscope settings change.ZAFRAN HUSSAIN SHAH MARCEL MÜLLER TUNG-CHENG WANG PHILIP MAURICE SCHEIDIG AXEL SCHNEIDER MARK SCHÜTTPELZ THOMAS HUSER WOLFRAM SCHENCK 2021Photonics Research2021,9,5:11
14Graphitic carbon nitride (g-C3N4)-based nanosized heteroarrays: Promising materials for photoelectrochemical water splitting显示文摘Photoelectrochemical(PEC)water splitting is recognized as a sustainable strategy for hydrogen generation due to its abundant hydrogen source,utilization of inexhaustible solar energy,high-purity product,and environment-friendly process.To actualize a practical PEC water splitting,it is paramount to develop efficient,stable,safe,and low-cost photoelectrode materials.Recently,graphitic carbon nitride(g-C3N4)has aroused a great interest in the new generation photoelectrode materials because of its unique features,such as suitable band structure for water splitting,a certain range of visible light absorption,nontoxicity,and good stability.Some inherent defects of g-C3N4,however,seriously impair further improvement on PEC performance,including low electronic conductivity,high recombination rate of photogenerated charges,and limited visible light absorption at long wavelength range.Construction of g-C3N4-based nanosized heteroarrays as photoelectrodes has been regarded as a promising strategy to circumvent these inherent limitations and achieve the high-performance PEC water splitting due to the accelerated exciton separation and the reduced combination of photogenerated electrons/holes.Herein,we summarize in detail the latest progress of g-C3N4-based nanosized heteroarrays in PEC water-splitting photoelectrodes.Firstly,the unique advantages of this type of photoelectrodes,including the highly ordered nanoarray architectures and the heterojunctions,are highlighted.Then,different g-C3N4-based nanosized heteroarrays are comprehensively discussed,in terms of their fabrication methods,PEC capacities,and mechanisms,etc.To conclude,the key challenges and possible solutions for future development on g-C3N4-based nanosized heteroarray photoelectrodes are discussed.Liqun Wang Wenping Si Yueyu Tong Feng Hou Daniele Pergolesi Jungang Hou Thomas Lippert Shi Xue Dou Ji Liang 2020Carbon Energy2020,2,2:10
15Strategies to anode protection in lithium metal battery:A review显示文摘Lithium metal batteries(LMBs)are considered the most promising energy stor-age devices for applications such as electrical vehicles owing to its tremendous theoretical capacity(3860 mAh g−1).However,the serious safety issues and poor cycling performance caused by the dendritic crystal growth during deposi-tion are concerned for any rechargeable batteries with a lithium metal anode.To make widespread adoption a possibility,considerable efforts have been devoted to suppressing lithium(Li)dendrite growth.In this review,the recent strategies to developing dendrite free Li anode,including constructing an artifi-cial solid electrolyte interface,current collector modification,separator film improvement,and electrolyte additive,are summarized.The merits and short-comings for different strategies are reviewed and a general summary and per-spective on the next generation rechargeable batteries are presented.Jiawei Li Zhao Kong Xiaoxi Liu Bocong Zheng Qi Hua Fan Elias Garratt Thomas Schuelke Keliang Wang Hui Xu Hong Jin 2021InfoMat2021,3,12:8

17A GmNINa-miR172c-NNC1 Regulatory Network Coordinates the Nodulation and Autoregulation of Nodulation Pathways in Soybean显示文摘Symbiotic root nodules are root lateral organs of plants in which nitrogen-fixing bacteria(rhizobia)convert atmospheric nitrogen to ammonia.The formation and number of nodules in legumes are precisely controlled by a rhizobia-induced signal cascade and host-controlled autoregulation of nodulation(AON).However,how these pathways are integrated and their underlying mechanisms are unclear.Here,we report that microRNA172c(miR172c)activates soybean(Glycine max)R hizobia-induced CLE1(GmRICI)and GmRIC2 by removing the transcriptional repression of these genes by Nodule Number Control 1(NNC1),leading to the activation of the AON pathway.NNC1 interacts with GmNINa,the soybean ortholog of Lotus NODULE INCEPTION(NIN),and hampers its transcriptional activation o i G m RICI and GmRIC2.Importantly,GmNINa acts as a transcriptional activator of miR172c.Intriguingly,NNC1 can transcriptionally repress miR172c expression,adding a negative feedback loop into the NNC1 regulatory network.Moreover,GmNINa interacts with NNC1 and can relieve the NNC1-mediated repression of miR172c transcription.Thus,the GmNINa-miR172c-NNC1 network is a master switch that coordinately regulates and optimizes NF and AON signaling,supporting the balance between nodulation and AON in soybean.Lixiang Wang Zhengxi Sun Chao Su Yongliang Wang Qiqi Yan Jiahuan Chen Thomas Ott Xia Li 2019Molecular Plant2019,12,9:7
18Chevrier's Field Mouse(Apodemus chevrieri) and Père David's Vole(Eothenomys melanogaster) in China Carry Orthohepeviruses that form Two Putative Novel Genotypes Within the Species Orthohepevirus C显示文摘Hepatitis E virus(HEV)is the prototype of the family Hepeviridae and the causative agent of common acute viral hepatitis.Genetically diverse HEV-related viruses have been detected in a variety of mammals and some of them may have zoonotic potential.In this study,we tested 278 specimens collected from seven wild small mammal species in Yunnan province,China,for the presence and prevalence of orthohepevirus by broad-spectrum reverse transcription(RT)-PCR.HEV-related sequences were detected in two rodent species,including Chevrier’s field mouse(Apodemus chevrieri,family Muridae)and Père David’s vole(Eothenomys melanogaster,family Cricetidae),with the infection rates of 29.20%(59/202)and 7.27%(4/55),respectively.Further four representative full-length genomes were generated:two each from Chevrier’s field mouse(named Rd HEVAc14 and Rd HEVAc86)and Père David’s vole(Rd HEVEm40 and Rd HEVEm67).Phylogenetic analyses and pairwise distance comparisons of whole genome sequences and amino acid sequences of the gene coding regions showed that orthohepeviruses identified in Chinese Chevrier’s field mouse and Père David’s vole belonged to the species Orthohepevirus C but were highly divergent from the two assigned genotypes:HEV-C1 derived from rat and shrew,and HEV-C2 derived from ferret and possibly mink.Quantitative real-time RT-PCR demonstrated that these newly discovered orthohepeviruses had hepatic tropism.In summary,our work discovered two putative novel genotypes orthohepeviruses preliminarily named HEVC3 and HEV-C4 within the species Orthohepevirus C,which expands our understanding of orthohepevirus infection in the order Rodentia and gives new insights into the origin,evolution,and host range of orthohepevirus.Bo Wang Wen Li Ji-Hua Zhou Bei Li Wei Zhang Wei-Hong Yang Hong Pan Li-Xia Wang Thomas Bock Zheng-Li Shi Yun-Zhi Zhang Xing-Lou Yang 2018Virologica Sinica2018,33,1:6
19Qidong: a crucible for studies on liver cancer etiology and prevention显示文摘Qidong(Jiangsu, China) has been of interest to cancer epidemiologists and biologists because, until recently, it was an endemic area for liver cancer, having amongst the highest incidence rates in the world. The establishment of the Qidong Cancer Registry together with the Qidong Liver Cancer Institute in 1972 has charted the patterns of liver cancer incidence and mortality in a stable population throughout a period of enormous economic, social, and environmental changes as well as of improvements in health care delivery. Updated incidence trends in Qidong are described. Notably, the China age-standardized incidence rate for liver cancer has dropped by over 50% in the past several decades. Molecular epidemiologic and genomic deep sequencing studies have affirmed that infection with hepatitis B virus as well as dietary exposure to aflatoxins through contamination of dietary staples such as corn, and to microcystins–blue-green algal toxins found in ditch and pond water – were likely important etiologic factors that account for the high incidence of liver cancer in this region. Public health initiatives to facilitate universal vaccination of newborns against HBV and to improve drinking water sources in this rural area, as well as economic and social mandates serendipitously facilitating dietary diversity, have led to precipitous declines in exposures to these etiologic factors, concomitantly driving substantive declines in the liver cancer incidence seen now in Qidong. In this regard, Qidong serves as a template for the global impact that a package of intervention strategies may exert on cancer burden.Jianguo Chen Jian Zhu Gaoren Wang John D.Groopman Thomas W.Kensler 2019Cancer Biology & Medicine2019,16,1:6
20Encyclopedia of fecal microbiota transplantation: a review of effectiveness in the treatment of 85 diseases显示文摘Fecal microbiota transplantation(FMT)has been used as a core therapy for treating dysbiosis-related diseases by remodeling gut microbiota.The methodology and technology for improving FMT are stepping forward,mainly including washed microbiota transplantation(WMT),colonic transendoscopic enteral tubing(TET)for microbiota delivery,and purified Firmicutes spores from fecal matter.To improve the understanding of the clinical applications of FMT,we performed a systematic literature review on FMT published from 2011 to 2021.Here,we provided an overview of the reported clinical benefits of FMT,the methodology of processing FMT,the strategy of using FMT,and the regulations on FMT from a global perspective.A total of 782 studies were included for the final analysis.The present review profiled the effectiveness from all clinical FMT uses in 85 specific diseases as eight categories,including infections,gut diseases,microbiotagut-liver axis,microbiotagut-brain axis,metabolic diseases,oncology,hematological diseases,and other diseases.Although many further controlled trials will be needed,the dramatic increasing reports have shown the promising future of FMT for dysbiosis-related diseases in the gut or beyond the gut.Yun Wang Sheng Zhang Thomas JBorody Faming Zhang 2022Chinese Medical Journal2022,135,16:6
