| 1 | Cloning of a gene-edited macaque monkey by somatic cell nuclear transfer显示文摘Cloning of macaque monkeys by somatic cell nucleus transfer(SCNT) allows the generation of monkeys with uniform genetic backgrounds that are useful for the development of non-human primate models of human diseases. Here, we report the feasibility of this approach by SCNT of fibroblasts from a macaque monkey(Macaca fascicularis), in which a core circadian transcription factor BMAL1 was knocked out by clustered regularly interspaced short palindromic repeat/Cas9 gene editing(see accompanying paper).Out of 325 SCNT embryos transferred into 65 surrogate monkeys, we cloned five macaque monkeys with BMAL1 mutations in both alleles without mosaicism, with nuclear genes identical to that of the fibroblast donor monkey. Further peripheral blood m RNA analysis confirmed the complete absence of the wild-type BMAL1 transcript. This study demonstrates that the SCNT approach could be used to generate cloned monkeys from fibroblasts of a young adult monkeys and paves the way for the development of macaque monkey disease models with uniform genetic backgrounds. | Zhen Liu Yijun Cai Zhaodi Liao Yuting Xu Yan Wang Zhanyang Wang Xiaoyu Jiang Yuzhuo Li Yong Lu Yanhong Nie Xiaotong Zhang Chunyang Li Xinyan Bian Mu-ming Poo Hung-Chun Chang Qiang Sun | 2019 | National Science Review2019,6,1: | 14 |
| 2 | Oncogenic AURKA-enhanced N6-methyladenosine modification increases DROSHA mRNA stability to transactivate STC1 in breast cancer stem-like cells显示文摘RNase III DROSHA is upregulated in multiple cancers and contributes to tumor progression by hitherto unclear mechanisms.Here,we demonstrate that DROSHA interacts withβ-Catenin to transactivate STC1 in an RNA cleavage-independent manner,contributing to breast cancer stem-like cell(BCSC)properties.DROSHA mRNA stability is enhanced by N6-methyladenosine(m^(6)A)modification which is activated by AURKA in BCSCs.AURKA stabilizes METTL14 by inhibiting its ubiquitylation and degradation to promote DROSHA mRNA methylation.Moreover,binding of AURKA to DROSHA transcript further strengthens the binding of the m^(6)A reader IGF2BP2 to stabilize m^(6)A-modified DROSHA.In addition,wild-type DROSHA,but not an m^(6)A methylation-deficient mutant,enhances BCSC stemness maintenance,while inhibition of DROSHA m^(6)A modification attenuates BCSC traits.Our study unveils the AURKA-induced oncogenic m^(6)A modification as a key regulator of DROSHA in breast cancer and identifies a novel DROSHA transcriptional function in promoting the BCSC phenotype. | Fei Peng Jie Xu Bai Cui Qilan Liang Sai Zeng Bin He Hong Zou Manman Li Huan Zhao Yuting Meng Jin Chen Bing Liu Shasha Lv Peng Chu Fan An Zifeng Wang Junxiu Huang Yajing Zhan Yuwei Liao Jinxin Lu Lingzhi Xu Jin Zhang Zhaolin Su Zhiguang Li Fangjun Wang Eric W-FLam Quentin Liu | 2021 | Cell Research2021,31,3: | 9 |
| 3 | Effects of Straw Incorporation Methods on Nitrous Oxide and Methane Emissions from a Wheat-Rice Rotation System显示文摘The incorporation of straw with a microbial inoculant(a mixture of bacteria and fungi, designed to accelerate straw decomposition)is being increasingly adopted within the agricultural sector in China. However, its effects on N and C trace gas emissions remain unclear.We conducted a field experiment to investigate the effects of different straw incorporation methods(with and without microbial inoculant) in the wheat season on nitrous oxide(N_2O) and methane(CH_4) emissions from a wheat-rice rotation system in China.The treatments comprised N, P, and K fertilizers only(NPK), NPK plus rice straw(NPKS), NPKS plus Ruilaite microbial inoculant(NPKSR), and NPKS plus Jinkuizi microbial inoculant(NPKSJ). Rice straw incorporation before wheat sowing significantly decreased N_2O emissions during the wheat season and stimulated N_2O and CH_4 emissions during the subsequent rice season. Compared with the NPKS treatment, the NPKSR and NPKSJ treatments decreased N_2O emissions during the wheat season, but had no effect on N_2O or CH_4 emissions during the subsequent rice season. Annually, the two treatments were comparable regarding N_2O emissions.Although the global warming potentials of the NPKSR and NPKSJ treatments were lower than that of the NPKS treatment during the wheat season, no significant differences were observed during the subsequent rice season, or over the entire rotation cycle. The annual greenhouse gas intensity was slightly lower in the NPKSR and NPKSJ treatments than in the NPKS treatment. Overall, these results suggest that the incorporation of rice straw with a microbial inoculant in the wheat season was the best strategy tested for managing straw resources within the wheat-rice rotation system. | LIU Gang MA Jing YANG Yuting YU Haiyang ZHANG Guangbin XU Hua | 2019 | Pedosphere2019,29,2: | 7 |
| 4 | Variations of Stable Carbon Isotopes of CH4 Emission from Three Typical Rice Fields in China显示文摘Little is known about the stable carbon isotopes of methane(CH4) emitted(δ^(13)CH_(4emitted)) from permanently flooded rice fields and double rice-cropping fields.The CH4 emission and corresponding δ^(13)CH_(4emitted) under various field managements(mulching,water regime,tillage,and nitrogen(N) fertilization) were simultaneously measured in three typical Chinese rice fields,a permanently flooded rice field in Ziyang City,Sichuan Province,Southwest China,a double-rice cropping field in Yingtan City,Jiangxi Province,Southeast China,and a rice-wheat rotation field in Jurong City,Jiangsu Province,East China,from 2010 to 2012.Results showed different seasonal variations of δ^(13)CH_(4emitted) among the three fields during the rice-growing season.The values of δ^(13)CH_(4emitted) were negatively correlated with corresponding CH4 emissions in seasonal variation and mean,indicating the importance of CH_4 production,oxidation,and transport associated with isotopic fractionation effects to the δ^(13)CH_(4emitted).Seasonal variations of δ^(13)CH_(4emitted) were slightly impacted by mulching cultivation,tillage,and N application,but highly controlled by drainage.Meanwhile,tillage,N application,and especially mulching cultivation had important effects on seasonal mean CH4 emissions and corresponding δ^(13)CH_(4emitted) with low emissions accompanied by high values of δ^(13)CH_(4emitted).Seasonal mean values of δ^(13)CH_(4emitted) from the three fields were similar,mostly ranging from —60‰ to — 50‰,which are well in agreement with previously published data.These demonstrated that seasonal variations of δ^(13)CH_(4emitted) mainly depended on the changes in CH4 emission from rice fields and further indicated the important effects of methanogenic pathways,CH4 oxidation,and CH4 transport associated with isotope fractionation effects influenced by field managements on δ^(13)CH_(4emitted). | ZHANG Guangbin MA Jing YANG Yuting YU Haiyang SHI Yaping XU Hua | 2017 | Pedosphere2017,27,1: | 6 |
| 5 | Performance Analysis of WLAN Medium Access Control Protocols in Simulcast Radio-Over-Fiber-Based Distributed Antenna Systems显示文摘The performance of three wireless local-area network(WLAN) media access control(MAC) protocols is investigated and compared in the context of simulcast radioover-fiber-based distributed antenna systems(RoF-DASs) where multiple remote antenna units(RAUs) are connected to one access point(AP) with different-length fiber links.The three WLAN MAC protocols under investigation are distributed coordination function(DCF) in basic access mode,DCF in request/clear to send(RTS/CTS) exchange mode,and point coordination function(PCF).In the analysis,the inter-RAU hidden nodes problems and fiber-length difference effect are both taken into account.Results show that adaptive PCF mechanism has better throughput performances than the other two DCF modes,especially when the inserted fiber length is short. | LI Jianqiang FAN Yuting CHEN Hao LU Xun XU Kun | 2014 | China Communications2014,11,5: | 5 |
| 6 | B-box proteins:Pivotal players in light-mediated development in plants^FA显示文摘Light signals mediate a number of physio-logical and developmental processes in plants, such as flowering, photomorphogenesis, and pigment accu-mulation. Emerging evidence has revealed that a group of B-box proteins (BBXs) function as central players in these light-mediated developmental processes. B-box proteins are a class of zinc-coordinated transcription factors or regulators that not only directly mediate the transcription of target genes but also interact with various other factors to create a complex regulatory network involved in the precise control of plant growth and development. This review summarizes and highlights the recent findings concerning the critical regulatory functions of BBXs in photoperiodic flow-ering, light signal transduction and light-induced pigment accumulation and their molecular modes of action at the transcriptional and post-translational levels in plants. | Zhaoqing Song Yeting Bian Jiujie Liu Yuting Sun Dongqing Xu | 2020 | Journal of Integrative Plant Biology2020,62,9: | 5 |
| 7 | Natural orifice transluminal endoscopic surgery in urology: The Chinese experience显示文摘Objective:To describe the Chinese experience of natural orifice transluminal endoscopic surgery(NOTES)in urology.Methods:From December 2008 to May 2017,35 animal experiments and 305 clinical surgeries of NOTES or natural orifices specimen extractions(NOSE)were performed in China.The animal experiments included five kidney biopsies,24 nephrectomies and six partial nephrectomies.The clinical surgeries included 12 transvaginal NOSE(TV-NOSE),266 hybrid transvaginal NOTES(TV-NOTES)and 27 pure TV-NOTES.The TV-NOSE procedure was performed in five transumbilical laparoendoscopic single-site(U-LESS)nephrectomies,four suprapubic-assisted laparoendoscopic single-site surgery(SA-LESS)nephroureterectomies,and three laparoscopic radical cystectomies.The hybrid TV-NOTES procedure included 210 nephrectomies,31 adrenalectomies,eight nephroureterectomies,13 partial nephrectomies,and four heminephrectomies.The pure TV-NOTES procedure included five renal cyst decortications and 22 nephrectomies.Results:A total of 29 animal experiments were successfully performed.One partial nephrectomy was converted to standard laparoscopic surgery.Two kidney biopsies and two nephrectomies were unsuccessful.A total of 297 clinical surgeries were successfully performed.Six patients who underwent hybrid TV-NOTES were converted to open surgery.Two patients who underwent pure TV-NOTES were converted to SA-LESS.There were 22 major complications,16 occurred intraoperatively and six postoperatively.The mean visual analog score(VAS)of 48 h after the operation was 2.5 points in TV-NOSE,2.3 points in hybrid TV-NOTES and 1.7 points in pure TV-NOTES.The mean follow-up of 50.6(3.0-87.0)months showed that all patients were in good condition.The umbilicus scars were nearly invisible in TV-NOSE and hybrid TV-NOTES.The vaginal incision healed well.Conclusions:TV-NOSE and TV-NOTES are feasible,safe,and effective with little injury,low pain,fast recovery,and good cosmetic outcomes in properly selected patients.They are worth consideration for urological clinical practice. | Xiaofeng Zou Guoxi Zhang Tianpeng Xie Yuanhu Yuan Rihai Xiao Gengqing Wu Xiaoning Wang Hui Xu Folin Liu Yuting Wu Yunfeng Liao Quanliang Liu Yinghao Sun Bo Yang Linhui Wang Chuanliang Xu Xiaofeng Gao | 2020 | Asian Journal of Urology2020,7,1: | 5 |
| 8 | Mitochondrial replacement in macaque monkey offspring by first polar body transfer显示文摘Dear Editor,Mitochondrial DNA(mtDNA)mutations are materally inherited to the offspring and mitochondrial replacement therapy(MRT)provides.a promising approach for preventing mtDNA-related 1,2 diseases.First polar body transfer(PB1T)has been used for mitochondrial replacement to generate mouse offspring and normal human embryos that yield embryonic stem cells.However,generation of primate offspring using PB1T has not been reported.Here,we show that PB1T-based mitochondrial replacement could generate healthy macaque monkey(Macaca fascicularis),a useful non-human primate model for evaluating methods that may improve the efficiency and safety of PB1T for MRT. | Zhanyang Wang Yuzhuo Li Xianfa Yang Yan Wang Yanhong Nie Yuting Xu Xiaotong Zhang Yong Lu Tikui Zhang Qiming Liu Naihe Jing Zhen Liu Qiang Sun | 2021 | Cell Research2021,31,2: | 4 |
| 9 | Purely organic optoelectronic materials with ultralong-lived excited states under ambient conditions显示文摘The exponential growth of utilizing synthetic organic molecules in optoelectronic applications poses strong demands for rational control over the excited states of the materials. The manipulation of excited states through molecular design has led to the development of high-performance optoelectronic devices with tunable emission colors, high quantum efficiencies and efficient energy/charge transfer processes. Recently, a significant breakthrough in lifetime tuning of excited states has been made;the purely organic molecules were found to have ultralonglived excited state under ambient conditions with luminescence lifetimes up to 1.35 s, which are several orders of magnitude longer than those of conventional organic fluorophores. Given the conceptual advance in understanding the fundamental behavior of excited state tuning in organic luminescent materials, the investigations of organic ultralong room-temperature phosphorescence(OURTP) should provide new directions for researches and have profound impacts on many different disciplines. Here, we summarized the recent understandings on the excited state tuning, the reported OURTP molecules and their design considerations,the spectacular photophysical performance, and the amazing optoelectronic applications of the newly emerged organic optoelectronic materials that free of heavy metals. | Jie Yuan Yuting Tang Shen Xu Runfeng Chen Wei Huang | 2015 | Science Bulletin2015,60,19: | 4 |
| 10 | Accelerated evolution of an Lhx2 enhancer shapes mammalian social hierarchies显示文摘Social hierarchies emerged during evolution,and social rank influences behavior and health of individuals.However,the evolutionary mechanisms of social hierarchy are still unknown in amniotes.Here we developed a new method and performed a genome-wide screening for identifying regions with accelerated evolution in the ancestral lineage of placental mammals,where mammalian social hierarchies might have initially evolved.Then functional analyses were conducted for the most accelerated region designated as placental-accelerated sequence 1(PAS1,P=3.15 × 10^-18).Multiple pieces of evidence show that PAS1 is an enhancer of the transcription factor gene Lhx2 involved in brain development.PAS1s isolated from various amniotes showed different c/s-regulatory activity in vitro,and affected the expression of Lhx2 differently in the nervous system of mouse embryos.PAS1 knock-out mice lack social stratification.PAS1 knock-in mouse models demonstrate that PAS1s determine the social dominance and subordinate of adult mice,and that social ranks could even be turned over by mutated PAS1.All homozygous mutant mice had normal huddled sleeping behavior,motor coordination and strength.Therefore,PAS1-Lhx2 modulates social hierarchies and is essential for establishing social stratification in amniotes,and positive Darwinian selection on PAS1 plays pivotal roles in the occurrence of mammalian social hierarchies. | Yuting Wang Guangyi Dai Zhili Gu Guopeng Liu Ke Tang Yi-Hsuan Pan Yujie Chen Xin Lin Nan Wu Haoshan Chen Su Feng Shou Qiu Hongduo Sun Qian Li Chuan Xu Yanan Mao Yong Edward Zhang Philipp Khaitovich Yan-Ling Wang Qunxiu Liu Jing-Dong Jackie Han Zhen Shao Gang Wei Chun Xu Naihe Jing Haipeng Li | 2020 | Cell Research2020,30,5: | 4 |
| 11 | Fabricating antibacterial CoCrCuFeNi high-entropy alloy via selective laser melting and in-situ alloying显示文摘A quasi-equiatomic CoCrFeCuNi high-entropy alloy(HEA) with a broad-spectrum antibacterial ability and good mechanical properties has been fabricated by selective laser melting(SLM) and in-situ alloying of a blend of pre-alloyed CoCrFeNi powder and Cu elemental powder.The as-built HEA alloy has a homogeneous distribution of Cu and presents a single FCC phase.Compared with the same HEA fabricated using the traditional ingot metallurgy(IM) process,the HEA alloy fabricated by SLM releases more Cu ions to prevent growth and biofilm formation by gram-negative Escherichia coli and gram-positive Staphylococcus aureus,which enhances the applicability of the HEA alloy in potential applications that requires antibacterial ability.The results of this study confirm the feasibility of combining the antibacterial CoCrFeCuNi HEA alloy and SLM technology in fabricating complex shaped parts or structures with a strong antibacterial ability to be used in medical application or other environments desired for antibacterial ability. | Jingbo Gao Yuting Jin Yongqiang Fan Dake Xu Lei Meng Cong Wang Yuanping Yu Deliang Zhang Fuhui Wang | 2022 | Journal of Materials Science & Technology2022,,7: | 4 |
| 12 | High-temperature phase transition behavior and magnetocaloric effect in a sub-rapidly solidified La–Fe–Si plate produced by centrifugal casting显示文摘A sub-rapidly solidified La Fe_(11.6)Si_(1.4)plate was fabricated directly from liquid by centrifugal casting method.The phase constitution,microstructure and magnetocaloric effect were investigated using backscatter scanning electron microscopy,X-ray diffraction,differential scanning calorimetry and physical property measurement system.When the plate was annealed at 1373 K,1 phase was formed by a solid-state peritectoid reaction.A first-order magnetic phase transition occurred in the vicinity of188 K,and the effective refrigeration capacities reached 203.5 J/kg and 209.7 J/kg in plates annealed for1 h and 3 h,respectively,under a magnetic field change of 3 T.It is suggested that centrifugal casting may become a new approach to prepare high-performance La–Fe–Si magnetocaloric plates for practical applications,which could largely accelerate the formation of 1 phase during high-temperature heat-treatment process due to refined and homogeneous honeycombed microstructure. | Zhishuai Xu Yuting Dai Yue Fang Zhiping Luo Ke Han Changjiang Song Qijie Zhai Hongxing Zheng | 2018 | Journal of Materials Science & Technology2018,34,8: | 4 |
| 13 | COPII mitigates ER stress by promoting formation of ER whorls显示文摘Cells mitigate ER stress through the unfolded protein response(UPR).Here,we report formation of ER whorls as an effector mechanism of the ER stress response.We found that strong ER stress induces formation of ER whorls,which contain ER-resident proteins such as the Sec61 complex and PKR-like ER kinase(PERK).ER whorl formation is dependent on PERK kinase activity and is mediated by COPII machinery,which facilitates ER membrane budding to form tubular-vesicular ER whorl precursors.ER whorl precursors then go through Sec22b-mediated fusion to form ER whorls.We further show that ER whorls contribute to ER stressinduced translational inhibition by possibly modulating PERK activity and by sequestering translocons in a ribosome-free environment.We propose that formation of ER whorls reflects a new type of ER stress response that controls inhibition of protein translation. | Fang Xu Wanqing Du Qin Zou Yuting Wang Xin Zhang Xudong Xing Ying Li Dachuan Zhang Huimin Wang Wenhao Zhang Xinyao Hu Xin Liu Xiaoling Liu Shaojin Zhang Jinqiang Yu Jianhuo Fang Fajin Li Ying Zhou Tieqiang Yue Na Mi Haiteng Deng Peng Zou Xiaowei Chen Xuerui Yang Li Yu | 2021 | Cell Research2021,31,2: | 4 |

| 15 | A Detection-Switching-Assisted DCF Mechanism for Simulcast WLAN-over-Fiber Based Distributed Antenna Systems显示文摘Distributed antenna systems(DASs) using Radio-over-fiber(Ro F) links is a promising candidate to provide flexible coverage and high data rates. For simulcast Wireless local-area network(WLAN) use in Ro F systems, the stations covered by different Remote antenna units(RAUs) contend for the wireless medium using Media access control(MAC) mechanism. Severe inter-RAU hidden nodes problem will happen due to the stations in different RAUs cannot detect each other very well. In order to alleviate this inter-RAU collision problem, a promising detection-switching-assisted Distributed coordination function(DCF) mechanism is presented using in the uplink. The control delay issues of the proposed mechanism are also discussed in this paper. | FAN Yuting LI Jianqiang XU Kun DAI Yitang | 2017 | Chinese Journal of Electronics2017,26,4: | 3 |
| 16 | Epithelial-mesenchymal transition status of circulating tumor cells in breast cancer and its clinical relevance显示文摘Objective:Circulating tumor cells(CTCs)play a critical role in cancer metastasis,but their prevalence and significance remain unclear.This study attempted to track the epithelial-mesenchymal transition(EMT)status of CTCs in breast cancer patients and investigate their clinical relevance.Methods:In this study,the established negFACS-IF:E/M platform was applied to isolate rare CTCs and characterize their EMT status in breast cancer.A total of 89 breast cancer patients were recruited,including stage 0–III(n=60)and late stage(n=29)cases.Results:Using the negFACS-IF:E/M platform,it was found that in human epidermal growth factor receptor 2(HER2)+patients,mesenchymal CTCs usually exhibited a high percentage of HER2+cells.Stage IV breast cancer patients had considerably more CTCs than stage 0–III patients.Among stage 0–III breast cancers,the HER2 subtype included a significantly higher percentage of mesenchymal and biphenotypic(epithelial and mesenchymal)CTCs than the luminal A or B subtypes.Among stage IV patients,CTCs were predominantly epithelial in cases with local recurrence and were more mesenchymal in cases with distant metastasis.By applying a support vector machine(SVM)algorithm,the EMT status of CTCs could distinguish between breast cancer cases with metastasis/local recurrence and those without recurrence.Conclusions:The negFACS-IF:E/M platform provides a flexible and generally acceptable method for the highly sensitive and specific detection of CTCs and their EMT traits in breast cancer.This study demonstrated that the EMT status of CTCs had high clinical relevance in breast cancer,especially in predicting the distant metastasis or local recurrence of breast cancer. | Jiaojiao Zhou Xuan Zhu Shijie Wu Jingxin Guo Kun Zhang Chunjing Xu Huihui Chen Yuxi Jin Yuting Sun Shu Zheng Yiding Chen | 2020 | Cancer Biology & Medicine2020,17,1: | 3 |
| 17 | Vesicle-shaped ZIF-8 shell shielded in 3D carbon cloth for uniform nucleation and growth towards long-life lithium metal anode显示文摘Lithium metal has aroused extensive research interests as the anode for next-generation rechargeable batteries.However,the well-known dendritic Li growth and consequent safety issues still impair the long-term cycling performance.Herein,a hybrid structure composed of 3 D carbon cloth and vesicleshaped hollow ZIF-8 modification shell(HZS@CC)was prepared as a smart host for guiding uniform Li deposition.The long-range interconnected 3 D carbon fiber network enables the reduced local current density with homogeneous electrons distribution.Synergistically,abundant surface polar groups and the ultrastructure on ZIF-8 particles effectively guide a well-distributed Li-ions flow to promote the uniform Li nucleation and growth.As a result,stable Li plating/stripping for 2000 h with a low overpotential(≈15 mV)at 1 mA cm^(-2) were achieved in symmetric cells.Coupling with LiFePO_(4) cathode,the full cell delivered long life over 1200 cycles at 6 C.This research demonstrated that a homogenization guiding of Li-ions is of great importance to better make use of the structural advantage of 3 D hosts and achieve improved electrochemical performance. | Yuting Fang Wenlong Cai Shanshan Zhu Kangli Xu Maogen Zhu Guannan Xiao Yongchun Zhu | 2021 | Journal of Energy Chemistry2021,30,3: | 2 |
| 18 | Porous hybrid scaffold strategy for the realization of lightweight,highly efficient microwave absorbing materials显示文摘Exploring an advanced and efficient electromagnetic(EM) wave absorbing material by improving dielectric loss capacity and adjusting impendence matching is crucial yet challenging. Herein, the bacterial cellulose(BC) derived carbon aerogel(CA) with a robust nanofibrous network was used as a conductive loss scaffold to dissipate EM waves effectively, and the Zn O microparticles with excellent dielectric properties and low electrical conductivity were decorated on the scaffold to adjust dielectric parameters and impedance matching adequately. By using different zinc precursors, the tunable size and morphologies of Zn O crystals were obtained due to the growth rate of different crystallographic, including flowerlike, nanorod like, and cauliflower-like morphologies, which is beneficial to strong multiple reflections,intensive interfacial polarization, better impendence matching, as well as excellent maintenance of the hierarchical structure. Owing to the appropriate impendence matching and the considerable EM wave dissipation, the CA@ZnO composites achieve a superior EM absorbing performance with a broad effective absorbing bandwidth(whole X band) and a minimum reflection coefficient(-53.3 d B). This work paves a new way for developing lightweight and highly efficient EM absorbing materials comprising the carbon scaffold and semiconductor microparticles. | Meng Zhu Yuting Lei Heng Wu Luo Kong Hailong Xu Xuanxuan Yan Yongjian Xu Lei Dai | 2022 | Journal of Materials Science & Technology2022,,34: | 2 |

| 20 | Laparoscopic vs.open surgery for gastrointestinal stromal tumors of esophagogastric junction:A multicenter,retrospective cohort analysis with propensity score weighting显示文摘Objective:Laparoscopic resection is increasingly performed for gastrointestinal stromal tumors(GISTs).However,the laparoscopic approach for GISTs located in the esophagogastric junction(EGJ-GIST)is surgically challenging.This study compares the efficacy of laparoscopic surgery and the open procedure for EGJ-GIST through the propensity score weighting(PSW)method.Methods:Between April 2006 and April 2018,1,824 surgical patients were diagnosed with primary gastric GIST at four medical centers in South China.Of these patients,228 were identified as EGJ-GISTs and retrospectively reviewed clinicopathological characteristics,operative information,and long-term outcomes.PSW was used to create the balanced cohorts.Results:PSW was carried out in laparoscopic and open-surgery cohorts according to year of surgery,sex,age,body mass index(BMI),tumor size,mitotic rates and recurrence risk.After PSW,438 patients consisting of 213 laparoscopic(L group)and 225 open surgery(O group)patients were enrolled.After PSW,the following measures in the L group were superior to those in the O group:median operative time[interquartile range(IQR)]:100.0(64.5-141.5)vs.149.0(104.0-197.5)min,P<0.001;median blood loss(IQR):30.0(10.0-50.0)vs.50.0(20.0-100.0)mL,P=0.002;median time to liquid intake(IQR):3.0(2.0-4.0)vs.4.0(3.0-5.0)d,P<0.001;median hospital stay(IQR):6.0(4.0-8.0)vs.7.0(5.0-12.0)d,P<0.001;and postoperative complications(10.3%vs.22.7%,P=0.001).The median follow-up was 55(range,2-153)months in the entire cohort.No significant differences were detected in either relapse-free survival(RFS)[hazard ratio(HR):0.372,95%confidence interval(95%CI):0.072-1.910,P=0.236]or overall survival(OS)(HR:0.400,95%CI:0.119-1.343,P=0.138)between the two groups.Conclusions:Laparoscopic surgery for EGJ-GIST is associated with the advantages of shorter operative time,reduced blood loss,shorter time to liquid intake,and shorter length of stay,all without compromising postoperative outcomes and long-term survival. | Wenjun Xiong Yuting Xu Tao Chen Xingyu Feng Rui Zhou Jin Wan Yong Li Guoxin Li Wei Wang | 2021 | Chinese Journal of Cancer Research2021,33,1: | 2 |
