| 1 | Effect of dietary soy oil, glucose, and glutamine on growth performance, amino acid profile, blood profile, immunity, and antioxidant capacity in weaned piglets显示文摘Weaning stress results in gastrointestinal dysfunction and depressed performance in pigs. This study aimed to investigate the effect of soy oil, glucose, and glutamine on the growth and health of weaned piglets. Compared with those in the glutamine group, piglets in the glucose and soy oil groups had greater average daily gain, average daily feed intake, and gain: feed ratio from day 0 to 14, and gain: feed ratio for the overall period. There were no differences with regard to serum amino acids among the three groups on day 14, except glycine and threonine. The serum concentration of histidine, serine, threonine, proline, and cysteine was the highest in the glutamine group, while the content of glycine and lysine in the soy oil group on day 28 was the highest among all groups. Piglets fed with glutamine had greater serum glucose and creatinine on day 14, high-density lipoprotein on day 28, and serum IgG and IgM on day 28. Piglets in the glutamine group demonstrated lower serum total superoxide dismutase on day 14 and 28; however, they demonstrated higher total superoxide dismutase and total antioxidant capacity in the duodenum and ileum on day 14. Weaned pigs supplemented with glucose or soy oil demonstrate better growth performance possibly due to their enhanced feed intake, whereas those supplemented with glutamine may have improved immunity and intestinal oxidative capacity. | Dinghong Lv Xia Xiong Huansheng Yang Meiwei Wang Yijie He Yanhong Liu Yulong Yin | 2018 | Science China(Life Sciences)2018,61,10: | 20 |
| 2 | Dietary supplementation of Bacillus subtilis influenced intestinal health of weaned pigs experimentally infected with a pathogenic E. coli显示文摘Background: There is growing evidence to support the beneficial effects of supplementing direct-fed microbials(DFM) on performance, health status, and immune responses of weaned pigs. Therefore, the objective of this study was to investigate dietary supplementation of Bacillus subtilis(DSM 25841) on growth performance, diarrhea, gut permeability and immunity of weaned pigs experimentally infected with a pathogenic F-18 Escherichia coli(E. coli).Results: The F18 E. coli infection reduced(P < 0.05) growth performance and intestinal villi height, whereas increased(P < 0.05) diarrhea and transcellular and paracellular permeability in the jejunum compared with non-challenged control. Supplementation of Bacillus subtilis linearly enhanced average daily gain of E. coli infected pigs from d 0 to 5 post-inoculation(PI)(P < 0.05) and d 0 to 11 PI(P = 0.058). Supplementation of high dose of Bacillus subtilis reduced(P < 0.05) both transcellular and paracellular permeability on d 5 and d11 PI compared with the E. coli infected pigs fed with control diet. E. coli infection up-regulated(P < 0.05)the m RNA expression of SLC5 A10(soluble carrier family 5 member 10) and MUC2(mucin 2) on d 5 PI, but down-regulated(P < 0.05) expression of SLC5 A10, MUC2, and CLDN1 on d 11 PI in jejunal mucosa when pigs were fed with the control diet. Supplementation of Bacillus subtilis linearly up-regulated(P < 0.05) the m RNA expression of CFTR and ZO1 on d 5 PI and SLC5 A10 and MUC2 on d 11 PI in jejunal mucosa of E. coli infected pigs. In addition, E. coli infection increased(P < 0.05) the m RNA expression of several immune genes(IL1 A, IL1 B, and IL7 on d 5 PI, and IL1 B, IL6, IL7, and TNF on d 11 PI) in the ileal mucosa of weaned pigs. Inclusion of Bacillus subtilis to control diet linearly down-regulated gene expression of IL1 A on d 5 PI(P = 0.07) and IL6 on d 11 PI(P < 0.05) in ileal mucosa of E. coli infected pigs.Conclusions: Supplementation of Bacillus subtilis(DSM 25841) enhanced growth rate and improved gut barrier function of weaned pigs experimentally infected with a pathogenic E. coli. | Kwangwook Kim Yijie He Xia Xiong Amy Ehrlich Xunde Li Helen Raybould Edward R.Atwill Elizabeth A.Maga Jens JΦrgensen Yanhong Liu | 2019 | Journal of Animal Science and Biotechnology2019,10,4: | 3 |
| 3 | Dietary Bacillus spp.enhanced growth and disease resistance of weaned pigs by modulating intestinal microbiota and systemic immunity显示文摘Background:Previous research has shown that dietary supplementation of Bacillus spp.probiotics exerts beneficial effects on animals’growth.However,limited studies have evaluated the efficacy of Bacillus spp.on weaned pigs and their effects on host gut health and microbiome,and systemic immunity using a disease challenge model.The objective of this experiment was to investigate the effects of two Bacillus spp.strains(Bacillus subtilis DSM 32540 and Bacillus pumilus DSM 32539)on growth performance,diarrhea,intestinal health,microbiome,and systemic immunity of weaned pigs experimentally infected with an enterotoxigenic Escherichia coli(ETEC).Results:Pigs in PRO1(Bacillus subtilis DSM 32540)had greater(P<0.05)body weight on d 7 and 14 PI,greater(P<0.05)ADG from d 0 to 7 and d 7 to 14 PI,compared with pigs in CON(Control).Pigs in PRO1 had milder(P<0.05)diarrhea on d 2 and 3 PI compared with pigs in CON.However,no differences were observed in growth performance and diarrhea score between PRO2(Bacillus pumilus DSM 32539)and CON groups.Supplementation of PRO1 decreased(P<0.05)lymphocyte counts on d 7 and 14 PI,compared with CON.Supplementation of PRO1 and PRO2 both reduced(P<0.05)total coliforms in mesenteric lymph nodes on d 21 PI.Pigs in PRO2 had greater(P<0.05)goblet cell number and sulfomucin percentage in duodenal villi and greater(P<0.05)sialomucin percentage in jejunal villi than pigs in CON.Supplementation of PRO1 up-regulated(P<0.05)MUC2 gene expression in jejunal mucosa and reduced(P<0.05)PTGS-2 and IL1B gene expression in ileal mucosa on d 21 PI,compared with CON.Pigs in PRO1 had reduced(P<0.05)relative abundance of families Lachnospiraceae,Peptostreptococcaceae and Pasteurellaceae in the ileum.Conclusions:Supplementation of Bacillus subtilis DSM 32540 improved growth performance,alleviated diarrhea severity,enhanced gut health,and reduced systemic inflammation of weaned pigs infected with ETEC F18.Although Bacillus pumilus DSM 32539 was able to alleviate systemic inflammation,it had limited impacts on growth performance and severity of diarrhea of ETEC F18 challenged weaned pigs. | Yijie He Cynthia Jinno Kwangwook Kim Zhaohai Wu Bie Tan Xunde Li Rose Whelan Yanhong Liu | 2021 | Journal of Animal Science and Biotechnology2021,12,2: | 2 |
| 4 | Elimination of a Retrotransposon for Quenching Genome Instability in Modern Rice显示文摘Transposable elements(TEs)constitute the most abundant portions of plant genomes and can dramatically shape host genomes during plant evolution.They also play important roles in crop domestication.However,whether TEs themselves are also selected during crop domestication has remained unknown.Here,we identify an active long terminal repeat(LTR)retrotransposon,HUO,as a potential target of selection during rice domestication and breeding.HUO is a low-copy-number LTR retrotransposon,and is active under natural growth conditions and transmitted through male gametogenesis,preferentially inserting into genomic regions capable of transcription.HUO exists in all wild rice accessions and about half of the archaeological rice grains(1200–7000 years ago)and landraces surveyed,but is absent in almost all modern varieties,indicating its gradual elimination during rice domestication and breeding.Further analyses showed that HUO is subjected to strict gene silencing through the RNA-directed DNA methylation pathway.Our results also suggest that multiple HUO copies may trigger genomic instability through altering genome-wide DNA methylation and small RNA biogenesis and changing global gene expression,resulting in decreased disease resistance and yield,coinciding with its elimination during rice breeding.Together,our study suggests that negative selection of an active retrotransposon might be important for genome stability during crop domestication and breeding. | Yu Peng Yingying Zhang Yijie Gui Dong An Junzhong Liu Xun Xu Qun Li Junmin Wang Wen Wang Chunhai Shi Longjiang Fan Baorong Lu Yiwen Deng Sheng Teng Zuhua He | 2019 | Molecular Plant2019,12,10: | 2 |
| 5 | Gastrin attenuates sepsis-induced myocardial dysfunction by down-regulation of TLR4 expression in macrophages显示文摘Myocardial dysfunction is the most serious complication of sepsis.Sepsis-induced myocardial dysfunction(SMD)is often associated with gastrointestinal dysfunction,but its pathophysiological significance remains unclear.The present study found that patients with SMD had higher plasma gastrin concentrations than those without SMD.In mice,knockdown of the gastrin receptor,cholecystokinin B receptor(Cckbr),aggravated lipopolysaccharide(LPS)-induced cardiac dysfunction and increased inflammation in the heart,whereas the intravenous administration of gastrin ameliorated SMD and cardiac injury.Macrophage infiltration plays a significant role in SMD because depletion of macrophages by the intravenous injection of clodronate liposomes,48 h prior to LPS administration,alleviated LPSinduced cardiac injury in Cckbr-deficient mice.The intravenous injection of bone marrow macrophages(BMMs)overexpressing Cckbr reduced LPS-induced myocardial dysfunction.Furthermore,gastrin treatment inhibited toll-like receptor 4(TLR4)expression through the peroxisome proliferator-activated receptor a(PPAR-a)signaling pathway in BMMs.Thus,our findings provide insights into the mechanism of the protective role of gastrin/CCKBR in SMD,which could be used to develop new treatment modalities for SMD. | Dandong Fang Yu Li Bo He Daqian Gu Mingming Zhang Jingwen Guo Hongmei Ren Xinyue Li Ziyue Zhang Ming Tang Xingbing Li Donghai Yang Chunmei Xu Yijie Hu Hongyong Wang Pedro AJose Yu Han Chunyu Zeng | 2023 | Acta Pharmaceutica Sinica B2023,13,9: | 1 |

| 8 | Deformation field and crack analyses of concrete using digital image correlation method显示文摘The study on the deformation distribution and crack propagation of concrete under axial compression was conducted by the digital image correlation (DIC) method. The main parameter in this test is the water-cement (fT/C) ratio. The novel analysis process and numerical program for DIC method were established. The displacements and strains of coarse aggregate, and cement mortar and interface transition zone (ITZ) were obtained and verified by experimental results. It was found that the axial displacement distributed non-uniformly during the loading stage, and the axial displacements of ITZs and cement mortar were larger than that of coarse aggregates before the occurrence of macrocracks. The effect of W/C on the horizontal displacement was not obvious. Test results also showed that the transverse and shear deformation concentration areas (DCAs) were formed when stress reached 30%-40% of the peak stress. The transverse and shear DCAs crossed the cement mortar, and ITZs and coarse aggregates. However, the axial DCA mainly surrounded the coarse aggregate. Generally, the higher W/C was, the more size and number of DCAs were. The crack propagations of specimens varied with the variation of W/C. The micro-crack of concrete mainly initiated in the ITZs, irrespective of the W/C. The number and distribution range of cracks in concrete with high W/C were larger than those of cracks in specimen adopting low W/C. However, the value and width of eraeks in high W/C specimen were relatively small. The W/C had an obvious effect on the characteristics of concrete deterioration. Finally, the characteristics of crack was also evaluated by comparing the calculated results. | Yijie HUANG Xujia HE Qing WANG Jianzhuang XIAO | 2019 | Frontiers of Structural and Civil Engineering2019,13,5: | 1 |
| 9 | microRNA regulation of fruit development,quality formation and stress response显示文摘Fruits,as the reproductive organs of many higher plants,are an integral part of a balanced diet,providing rich nutrients and bioactive substances for our health.Over the years,the research on fruit development,quality formation and stress response has deepened,which sheds light on the regulatory mechanism and application of fruit quality improvement.Among the many regulatory factors,microRNAs(miRNAs)are a class of short non-coding RNAs,ranging from 20 to 24-nt,which post-transcriptionally regulate target gene expression.miRNAs and their functions have been extensively examined in plants especially in model species,and they play critical roles in the regulation of diverse biological processes in response to endogenous developmental signals and external environmental cues,respectively.In fruit crops,the function of miRNAs and their regulation have also been under intensive study.In particular,the novel roles of miRNAs that have not been revealed in the model annual species have been unraveling,which reflect the genetic,physiological,and developmental complexity of gene regulation in fruit crops.Here we review the current research progress achieved,specifically in fruit crops,with a focus on the function of miRNAs in the control of fruit development and quality as well as response to various stresses.The future prospects of miRNAs for quality-targeted fruit breeding are also discussed. | Xiangjin Kong Meiying He Zhihong Guo Yijie Zhou Zhongsuzhi Chen Hongxia Qu Hong Zhu | 2021 | Fruit Research2021,1,1: | 1 |

| 11 | Arabidopsis DXO1 possesses deNADding and exonuclease activities and its mutation affects defense-related and photosynthetic gene expression^FA显示文摘RNA capping and decapping tightly coordinate with transcription,translation,and RNA decay to regulate gene expression.Proteins in the DXO/Rai1 family have been implicated in mRNA decapping and decay,and mammalian DXO was recently found to also function as a decapping enzyme for NAD+-capped RNAs(NAD-RNA).The Arabidopsis genome contains a single gene encoding a DXO/Rai1 protein,AtDXO1.Here we show that AtDXO1 possesses both NAD-RNA decapping activity and 5?-3?exonuclease activity but does not hydrolyze the m7G cap.The atdxo1 mutation increased the stability of NAD-RNAs and led to pleiotropic phenotypes,including severe growth retardation,pale color,and multiple devel-opmental defects.Transcriptome profiling analysis showed that the atdxo1 mutation resulted in upregulation@of defense-related genes but downregulation of photo-synthesis-related genes.The autoimmunity phenotype of the mutant could be suppressed by either eds1 or npr1 mutation.However,the various phenotypes associated with the atdxo1 mutant could be complemented by an enzymatically inactive AtDXO1.The atdxo1 mutation ap-parently enhances post-transcriptional gene silencing by elevating levels of siRNAs.Our study indicates that AtDXO1 regulates gene expression in various biological and physiological processes through its pleiotropic mo-lecular functions in mediating RNA processing and decay. | Shuying Pan Kai-en Li Wei Huang Huan Zhong Huihui Wu Yuan Wang He Zhang Zongwei Cai Hongwei Guo Xuemei Chen Yiji Xia | 2020 | Journal of Integrative Plant Biology2020,62,7: | 1 |

| 15 | Manganese-Catalyzed Hydrocar bofun ctionalization of Internal Alkenes显示文摘Summary of main observation and conclusion A highly regio-and chemo-selective dimeric Mn⑴-catalyzed hydroarylation and hydroalkenylation of unbiased internal alkenes with commercially abundant organoboron compounds is reported.A wide range of densely functionalized aliphatic alkenyl amides can successfully undergo site-exclusive hydrocarbofunctionalization in air atmosphere without any exogenous directing auxiliary,affording an enhanced lead library of structurally diverse y-functionalized carboxylic acid derivatives in moderate to good yields.The precise chemoselectivity of the reaction among multiple alkene units even in the presence of reactive terminal alkenes highlights the unique catalytic features of manganese catalyst,and the excellent functional group compatibility of primary amides further complements other transition metals. | Dongping Wang Yijie He Haotian Dai Congcong Huang Xiang-Ai Yuan Jin Xie | 2020 | Chinese Journal of Chemistry2020,38,12: | 1 |
| 16 | Towards higher-dimensional structured light显示文摘Structured light refers to the arbitrarily tailoring of optical fields in all their degrees of freedom(DoFs),from spatial to temporal.Although orbital angular momentum(OAM)is perhaps the most topical example,and celebrating 30 years since its connection to the spatial structure of light,control over other DoFs is slowly gaining traction,promising access to higher-dimensional forms of structured light.Nevertheless,harnessing these new DoFs in quantum and classical states remains challenging,with the toolkit still in its infancy.In this perspective,we discuss methods,challenges,and opportunities for the creation,detection,and control of multiple DoFs for higher-dimensional structured light.We present a roadmap for future development trends,from fundamental research to applications,concentrating on the potential for larger-capacity,higher-security information processing and communication,and beyond. | Chao He Yijie Shen Andrew Forbes | 2022 | Light(Science & Applications)2022,11,8: | 1 |
| 17 | Enhanced degradation of organic contaminants by Fe(Ⅲ)/peroxymonosulfate process with L-cysteine显示文摘The difficulty in Fe(Ⅲ)/Fe(Ⅱ) conversion in the Fe(Ⅲ)/peroxymonosulfate(PMS) process limits its efficiency and application.Herein,L-cysteine(Cys),a green natural organic ligand with reducing capability,was innovatively introduced into Fe(Ⅲ)/PMS to construct an excellent Cys/Fe(Ⅲ)/PMS process.The Cys/Fe(Ⅲ)/PMS process,at room temperature,can degrade a variety of organic contaminants,including dyes,phenolic compounds,and pharmaceuticals.In subsequent experiments with acid orange 7(A07),the AO7 degradation efficiency followed pseudo-first-order kinetic which exhibited an initial 'fast stage' and a second 'slow stage'.The rate constant values ranged depending on the initial Cys,Fe(Ⅲ),PMS,and AO7 concentrations,reaction temperature,and pH values.In addition,the presence of Cl^(-),NO_(3)^(-),and SO_(4)^(2-) had negligible impact while HCO_(3)^(-) and humic acid inhibited the degradation of AO7.Furthermore,radical scavenger experiments and methyl phenyl sulfoxide(PMSO) transformation assay indicated that sulfate radical,hydroxyl radical,and ferryl ion(Fe(Ⅳ)) were the dominant reactive species involved in the Cys/Fe(Ⅲ)/PMS process.Finally,based on the results of gas chromatography-mass spectrometry,several AO7 degradation pathways,including N=N cleavage,hydroxylation,and ring opening were proposed.This study provided a new insight to improve the efficiency of Fe(Ⅲ)/PMS process by accelerating Fe(Ⅲ)/Fe(Ⅱ)cycle with Cys. | Chengdu Qi Yanni Wen Yijie Zhao Yinhao Dai Yanping Li Chenmin Xu Shaogui Yang Huan He | 2022 | Chinese Chemical Letters2022,33,4: | 1 |
| 18 | Supplementation of oligosaccharide-based polymer enhanced growth and disease resistance of weaned pigs by modulating intestinal integrity and systemic immunity显示文摘Background:There is a great demand for antibiotic alternatives to maintain animal health and productivity.The objective of this experiment was to determine the efficacy of dietary supplementation of a blood group A6 type 1antigen oligosaccharides-based polymer(Coligo)on growth performance,diarrhea severity,intestinal health,and systemic immunity of weaned pigs experimentally infected with an enterotoxigenic Escherichia coli(ETEC),when compared with antibiotics.Results:Pigs in antibiotic carbadox or Coligo treatment groups had greater(P<0.05)body weight on d 5 or d 11post-inoculation(PI)than pigs in the control group,respectively.Supplementation of antibiotics or Coligo enhanced(P<0.05)feed efficiency from d 0 to 5 PI and reduced(P<0.05)frequency of diarrhea throughout the experiment,compared with pigs in the control group.Supplementation of antibiotics reduced(P<0.05)fecalβ-hemolytic coliforms on d 2,5,and 8 PI.Pigs in antibiotics or Coligo groups had reduced(P<0.05)neutrophil counts and serum haptoglobin concentration compared to pigs in the control group on d 2 and 5 PI.Pigs in Coligo had reduced(P<0.05)total coliforms in mesenteric lymph nodes on d 5 and 11 PI,whereas pigs in antibiotics or Coligo groups had reduced(P<0.05)total coliforms in spleen on d 11 PI compared with pigs in the control group.On d 5 PI,pigs in the Coligo group had greater(P<0.05)gene expression of ZO1 in jejunal mucosa,but less(P<0.05)m RNA expression of IL1B,IL6,and TNF in ileal mucosa,in comparison with pigs in the control group.Supplementation of antibiotics enhanced(P<0.05)the gene expression of OCLN in jejunal mucosa but decreased(P<0.05)IL1B and IL6 gene expression in ileal mucosa,compared with the control.On d 11 PI,supplementation of antibiotics or Coligo up-regulated(P<0.05)gene expression of CLDN1 in jejunal mucosa,but Coligo reduced(P<0.05)IL6 gene expression in ileal mucosa compared to pigs in the control group.Conclusions:Supplementation of Coligo improved growth performance,alleviated diarrhea severity,and enhanced gut health in weaned pigs infected with ETEC F18 in a manner similar to in-feed antibiotics. | Kwangwook Kim Yijie He Cynthia Jinno Lauren Kovanda Xunde Li David Bravo Eric Cox Yanhong Liu | 2022 | Journal of Animal Science and Biotechnology2022,13,3: | 0 |
| 19 | A new method to prepare calcium oxalate films for marble protection显示文摘Artificial calcium oxalate films have been applied to protect sculptures,monuments,and buildings made of marble due to their potential protective capacities.Unfortunately,artificially prepared calcium oxalate films are usually loose,and easy to peel off in contrast to the natural ones.In this paper,a new method was developed for the preparation of a compact and cohesive calcium oxalate film,using ethylene glycol as an additive.The morphology,elemental composition,structure,and crystal phase of the film were analyzed by SEM,EDX,IR,and XRD,and the protective effects were investigated by acid resistance test,while its adhesion to the underlying marble by the Scotch tape test.The porosity,water absorption,and color of treated marble were also assessed.The results showed that a calcium oxalate film with a compact structure,good adhesion,and a protective effect against acid rain can be successfully obtained by including ethylene glycol as an additive.With the new preparation method,a better bond between the stone and the film is obtained which contributes to solving the spalling problem of the artificial calcium oxalate films. | HE Lu JIANG YiJie MA WenTing LIU Yan YANG FuWei LU RuiCong WANG Lu ZHANG Kun CHEN XinNan GAO Xiang | 2023 | Science China(Technological Sciences)2023,66,8: | 0 |
| 20 | 仔猪生长缓慢的行为信号显示文摘文章介绍了美国明尼苏达大学(University of Minnesota)的一项有关仔猪福利方面的研究。此项研究的目的是确定料槽对保育期生长快慢和仔猪行为的影响。保育猪n=192;初始重(7.4±1.6)kg)置于24个圈栏中(每圈8头),其中12个猪圈配备了2个槽口的料槽(另外12个圈配5个槽口料槽)。根据商品猪上市时校正体重,将猪分为生长较慢(SG)和生长较快(FG)两组(SG<105 kg;FG≥105 kg)。进入保育舍后头4 d和第21天对仔猪的行为进行录像记录,9周龄时对96头试验猪进行摄食率测定。研究结果表明,属于SG组的猪用于饮水的时间较FG组要长(P<0.05);与配有2个槽口的相比,属于SG组里配有5个槽口圈栏的猪站或走的时间要少(P<0.05)。这些结果表明,提供更多槽口的喂料器可能有利于改善猪的福利。 | 张振玲(编译) yijie he john deen gerald c.shurson yuzhi z.li | 2018 | 猪业科学2018,35,8: | 0 |
