1Effect of various crop rotations on rice yield and nitrogen use efficiency in paddy–upland systems in southeastern China显示文摘To evaluate the effects of various rotation systems on rice grain yield and N use efficiency, a paddy–upland cropping experiment(2013–2016) was conducted in southeastern China. The experiment was designed using six different rice––winter crop rotations: rice–fallow(RF),rice–wheat(RW), rice–potato with rice straw mulch(RP), rice–green manure(Chinese milk vetch; RC–G), rice–oilseed rape(RO), and rice–green manure crop(oilseed rape with fresh straw incorporated into soil at flowering; RO–G) and three N rates, N0(0 kg N ha-1), N1(142.5 kg N ha-1), and N2(202.5 kg N ha-1). Average rice yields in the RF(5.93 t ha-1) rotation were significantly lower than those in the rotations with winter crops(7.20–7.48 t ha-1)under the N0 treatment, suggesting that incorporation of straw might be more effective for increasing soil N than winter fallow. The rice yield differences among the rotations varied by year with the N input. In general, the grain yields in the RP and RO–G rotations –were respectively 11.6–28.5% and 14.80–37.19% higher than those in the RF in plots with N applied. Increasing the N rate may have tended to minimize the average yield gap between the RF and the other rotations; the yield gaps were 18.55%, 4.14%, and 0.23% in N0, N1, and N2, respectively. However, the N recovery efficiency in the RF was significantly lower than that in other rotations, except for 2015 under both N1 and N2 rates, a finding that implies a large amount of chemical N loss. No significant differences in nitrogen agronomic efficiency(NAE) and physiological efficiency(NPE) were found between the rotations with legume(RC–G) and non–legume(RO and RW) winter crops, a result that may be due partly to straw incorporation. For this reason, we concluded that the return of straw could reduce differences in N use efficiency between rotations with and without legume crops. The degree of synchrony between the crop N demand and the N supply was evaluated by comparison of nitrogen balance degree(NBD) values. The NBD values in the RP and RW were significantly lower than those in the other rotations under both N1 and N2 rates. Thus,in view of the higher grain yield in the RP compared to the RW under the N1 rate, the RP rotation might be a promising practice with comparable grain yield and greater N use efficiency under reduced N input relative to the other rotations. The primary yield components of the RF and RP were identified as number of panicles m-2 and numbers of kernels panicle-1, respectively. The NAE and NPE were positively correlated with harvest index, possibly providing a useful indicator for evaluating N use efficiency.Song Chen Shaowen Liu Xi Zheng Min Yin Guang Chu Chunmei Xu Jinxiang Yan Liping Chen Danying Wang Xiufu Zhang 2018The Crop Journal2018,6,6:13
2Exosomes with low miR-34c-3p expression promote invasion and migration of non-small cell lung cancer by upregulating integrinα2β1显示文摘Exosomes play critical roles in regulating various physiological and pathological processes,including immune stimulation,immune suppression,cardiovascular diseases,and cancers.Recent studies show that exosomes that transport specific microRNAs(miRNAs)are involved in tumor development.However,the molecular mechanism by which tumor invasion and migration are regulated by exosomes from non-small cell lung cancer(NSCLC)is not well understood.Here,we show that exosomes shuttling low levels of miR-34c-3p are involved in NSCLC progression.Our results showed that exosomes derived from NSCLC cells carrying low levels of miR-34c-3p could be transported into the cytoplasm of NSCLC cells and accelerate NSCLC invasion and migration by upregulating integrinα2β1.A luciferase assay revealed that integrinα2β1 was the direct target of miR-34c-3p,and overexpression of integrinα2β1 could promote the invasion and migration of NSCLC cells.The analysis of exosomes derived from clinical serum samples indicated that the expression of miR-34c-3p was significantly downregulated in exosomes from NSCLC patients compared with that of normal controls.A549-derived exosomes promoted NSCLC cells lung metastases in vivo.Exosomes shuttling low levels of miR-34c-3p were associated with the progression of NSCLC in vitro and in vivo.Our data demonstrate that exosomes shuttling low levels of miR-34c-3p can accelerate the invasion and migration of NSCLC by upregulating integrinα2β1.MiR-34c-3p can be a diagnostic and prognostic marker for NSCLC.High expression of integrinα2β1 is positively related to the migration and metastasis of NSCLC cells.Wenjing Huang Yanyan Yan Yun Liu Minting Lin Jinxiang Ma Wei Zhang Jianwei Dai Jiajun Li Qiaoru Guo Hubiao Chen Bolat Makabel Hong Liu Chaoyue Su Hong Bi Jianye Zhang 2020Signal Transduction and Targeted Therapy2020,5,1:5
3Phase 1 studies comparing safety, tolerability, pharmacokinetics and pharmacodynamics of HLX01(a rituximab biosimilar) to reference rituximab in Chinese patients with CD20-positive B-cell lymphoma显示文摘Objective: This study aimed to compare the pharmacokinetic, pharmacodynamic and safety profiles of HLX01(a rituximab biosimilar) and reference rituximab sourced from China(Mab Thera?;rituximab-CN).Methods: Here we report the results of two phase 1 studies. In the phase 1 a, open-label, dose-escalation study(NCT03218072, CTR20140400), eligible patients received 250, 375 and 500 mg/m^(2) HLX01 sequentially at 7-day intervals, after confirming no dose-limiting toxicity(DLT). In the phase 1 b, double-blind study(NCT02584920,CTR20140764), eligible patients were given a single dose of 375 mg/m^(2) HLX01 or rituximab-CN. The primary endpoints included safety and tolerability parameters for the phase 1 a and the area under the plasma concentrationtime curve from time zero to day 91(AUC0-91 d) for the phase 1 b study. Equivalence was concluded if 90%confidence interval(90% CI) for the geometric least squares mean ratio(GLSMR) fell in the pre-specified equivalence criteria(80%-125%).Results: Between June 20, 2014 and January 5, 2015, 12 patients were enrolled in the phase 1 a study. The pharmacokinetics of HLX01 showed dose proportionality and accumulation to steady state. HLX01 was well tolerated, with no serious adverse events(AEs), discontinuations or DLTs. Between November 8, 2014 and August13, 2015, 87 eligible patients were enrolled in the phase 1 b study, including 43 who received HLX01 and 44 who were treated with rituximab-CN. The equivalence endpoint was met with GLSMR for AUC0-91 d being 89.6%(90% CI: 80.4%-99.8%). AEs, anti-drug antibodies, and CD19+ and CD20+ B lymphocyte counts were similar between the HLX01 and rituximab-CN treatment groups.Conclusions: Treatment with HLX01 was safe and well tolerated in Chinese patients with B-cell lymphoma.HLX01 and rituximab-CN have similar pharmacokinetic, pharmacodynamic and safety profiles.Yuankai Shi Qingyuan Zhang Xiaohong Han Yan Qin Xiaoyan Ke Hang Su Li Liu Jinxiang Fu Jie Jin Jifeng Feng Xiaonan Hong Xiaohong Zhang Depei Wu Bin Jiang Xiaodong Dong 2021Chinese Journal of Cancer Research2021,33,3:5
4Weighted Correlation Network Analysis(WGCNA) of Japanese Flounder(Paralichthys olivaceus) Embryo Transcriptome Provides Crucial Gene Sets for Understanding Haploid Syndrome and Rescue by Diploidization显示文摘Artificial gynogenesis is of great research value in fish genetics and breeding technology. However, existing studies did not explain the mechanism of some interesting phenomena. Severe developmental defects in gynogenetic haploids can lead to death during hatching. After diploidization of chromosomes, gynogenetic diploids may dispense from the remarkable malformation and restore the viability, although the development time is longer and the survival rate is lower compared with normal diploids. The aim of this study was to reveal key mechanism in haploid syndrome of Japanese flounder, a commercially important marine teleost in East Asia. We measured genome-scale gene expression of flounder haploid, gynogenetic diploid and normal diploid embryos using RNA-Seq, constructed a module-centric co-expression network based on weighted correlation network analysis(WGCNA) and analyzed the biological functions of correlated modules. Module gene content analysis revealed that the formation of gynogenetic haploids was closely related to the abnormality of plasma proteins, and the up-regulation of p53 signaling pathway might rescue gynogenetic embryos from haploid syndrome via regulating cell cycle arrest, apoptosis and DNA repair. Moreover, normal diploid has more robust nervous system. This work provides novel insights into molecular mechanisms in haploid syndrome and the rescue process by gynogenetic diploidization.ZHAO Haitao DU Xinxin ZHANG Kai LIU Yuezhong WANG Yujue LIU Jinxiang HE Yan WANG Xubo ZHANG Quanqi 2018Journal of Ocean University of China2018,17,6:3

10Multi-chambered,carbon-coated Ni_(0.4)Fe_(2.6)O_(4) nanoparticle superlattice microspheres for boosting water oxidation reaction显示文摘Developing active and robust non-noble-metal-based electrocatalysts for the oxygen evolution reaction(OER)is of vital practical significance for accelerating the kinetics of water splitting.Here,a novel double emulsion template method is proposed to design and prepare hierarchically multichambered,carbon-coated Ni_(0.4)Fe_(2.6)O_(4) nanoparticle superlattice microspheres(M-NFO@C-NSMs)for the highly efficient oxygen evolution.The high-temperature calcination under inert gas enables an improved electrochemical property by rationally transforming the long-chain organic capping ligands into partially graphitized uniform carbon coatings.More importantly,benefiting from the unique hierarchical superstructure with macro-/meso-/microporosities and three-dimensional continuous conductive carbon frameworks,M-NFO@C-NSMs exhibit comprehensively enhanced OER activity in a dilute alkaline electrolyte as compared to their solid counterparts and most spinelbased electrocatalysts reported to date.Notably,the collective property of supraparticles endowed M-NFO@C-NSMs with superior long-term cyclic stability.This work sheds light on the sophisticated design of functionalized supraparticles for efficient water splitting.Mingzhong Li Yuwei Deng Guanhong Wu Shuqing Xue Yancui Yan Zihan Liu Jinxiang Zou Dong Yang Angang Dong 2021Aggregate2021,2,2:0
11Direct synthesis of a disinfectant with fresh scent of green plants by semi-hydrogenation of alkynol on Pd single-atom catalysts显示文摘Alcohol-based disinfectants have protected people in the coronavirus disease 2019(COVID-19)pandemic,but olfactory stimuli of ethanol may evoke unpleasant memories associated with stressful situations in the devastating infectious disease.The smell of ethanol in household cleaning and disinfectant products can be covered up by the fragrance additives,and 3-hexenol is especially appreciated for the characteristic,strong odor of green plants.Industrial production of 3-hexenol relies on the selective hydrogenation of 3-hexyn-1-ol,where Lindlar catalyst is normally used for the superior selectivity.Although achieving such catalytic transformation in ethanol solution seems as a direct way to produce a disinfectant with green aroma,a popular consumer product in the post-COVID era,severe leaching of toxic Pb hinders Lindlar catalyst as a promising candidate.We find that the Fe_(2)O_(3) supported Pd single-atom catalyst is highly selective to fulfill semi-hydrogenation of 3-hexyn-1-ol in 75%ethanol,and the aforementioned household product is readily generated after filtrating the stable,solid catalyst out of reaction solution.Single-atom catalysts have been frequently utilized for fine-chemical synthesis,while in this work they make stunning debut in practical manufacture of daily used products.Yan Jiang Xuetong Yu Yuxia Ji Xunzhu Jiang Yalin Guo Tianbo Li Liang Gao Rui Lang Yanxiong Fang Botao Qiao Jinxiang Dong 2024Nano Research2024,17,5:0
12Molecular Characterization, Expression Pattern and Transcriptional Regulation of Figla During Gonad Development in Japanese Founder (Paralichthys olivaceus)显示文摘The factor in the germline alpha(figla), as a member of the basic helix-loop-helix family, has been reported to be involved in ovary development in mammals and teleosts. However, the regulatory mechanisms of figla in teleosts remain unclear. Here,figla in P. olivaceus(Pofigla) was characterized with encoding a 202 amino acid protein that contains a conserved basic region and helix-loop-helix(HLH) domain. Amino acids alignment and synteny analysis revealed that Pofigla was conserved with the orthologous gene sequences in other vertebrates. The results of qRT-PCR showed Pofigla was maternally inherited during embryonic development. For tissue distribution, Pofigla showed a sexually dimorphic gene expression in the gonad of different genders, with a higher expression in ovary than in testis. In situ hybridization(ISH) results demonstrated Pofigla was specifically expressed in germ cells including oocytes, spermatogonia and spermatocytes. By screening and analyzing two proximal regions(-2966/-2126 and-772/-444) with high promoter activity, we found SOX5, LEF1, FOXP1 and GATA1 may play important roles in the transcriptional regulation of Pofigla. Furthermore, we observed the co-localization between Figla and LEF1 in HEK 293T cells. And the significant up-regulation effect of the canonical Wnt signaling pathway on the expression of Pofigla was found in cultured ovarian cells. This study provided the first evidence that figla not only has an important function in ovary development, but also plays some potential roles in testis development and/or male germ cell differentiation during early testis development in P. olivaceus. The results provide valuable reference in exploring the regulatory network of figla in teleost.QU Jiangbo LI Rui LIU Yuxiang SUN Minmin YAN Weijie LIU Jinxiang WANG Xubo ZHANG Quanqi 2022Journal of Ocean University of China2022,21,4:0
