| 1 | Probiotic effect of ferulic acid esterase-producing Lactobacillus plantarum inoculated alfalfa silage on digestion,antioxidant,and immunity status of lactating dairy goats显示文摘A feeding experiment was conducted to determine the effects of inoculating alfalfa silage with a ferulic acid esterase-producing inoculum on feed digestibility,rumen fermentation,antioxidant,and immunity status of lactating dairy goats.Twenty dairy goats were distributed into 2 experimental groups consisting of control diet(Lp MTD/1,including Lactobacillus plantarum MTD/1 inoculated silage)against diet containing silage treated with ferulic acid esterase-producing L.plantarum A1(Lp A1).Alfalfa silage inoculated with a ferulic acid esterase-producing Lp A1 had better fermentation quality than the Lp MTD/1inoculation.The application of Lp A1 improved silage antioxidant capacity as indicated by greater total antioxidant capacity(T-AOC),superoxide dismutase(SOD)and glutathion peroxidase(GSH-Px)activities in Lp A1 treated silage versus Lp MTD/1 treatment.Compared with Lp MTD/1 treated group,inoculation of silage with Lp A1 increased apparent total tract digestibility of dietary dry matter,organic matter and crude protein,and ruminal concentrations of total volatile fatty acids,acetate,propionate and isobutyrate as well.The results of current study also demonstrated improved antioxidant capacity and immune performance of dairy goats with Lp A1 inoculation.Feeding Lp A1-treated silage increased dairy goats’serum antioxidase activity,such as T-AOC,SOD,GSH-Px and catalase,and the serum concentration of immunoglobulin A,while decreased tumor necrosis factor a,interleukin(IL)-2 and IL-6.In addition,compared with Lp MTD/1,diet containing alfalfa silage inoculated with Lp A1 endowed dairy goats’milk with greater fat and protein contents,improved dairy goat milk quality without affecting feed efficiency. | Fuhou Li Baibing Zhang Yixin Zhang Xia Zhang Samaila Usman Zitong Ding Lizhuang Hao Xusheng Guo | 2022 | Animal Nutrition2022，，4： | 6 |
| 2 | Effect of Bacillus amyloliquefaciens and Bacillus subtilis on fermentation, dynamics of bacterial community and their functional shifts of whole-plant corn silage显示文摘Background:Bacillus amyloliquefaciens(BA)and Bacillus subtilis(BS)are usually used as feed supplements directly or bacterial inoculants in biological feeds for animals.However,few research have reported the effects of BA and BS on fermentation characteristics and bacterial community successions of whole-plant corn silage during ensiling.If the BA and BS inoculants have positive effects on silages,then they could not only improve fermentation characteristics,but also deliver BA or BS viable cells to ruminants,which would play its probiotic effect.Therefore,the objectives of this study were to investigate the effects of BA and BS on the fermentation,chemical characteristics,bacterial community and their metabolic pathway of whole-plant corn silage.Results:Freshly chopped whole-plant corn was inoculated without or with BA and BS,respectively,and ensiled for1,3,7,14 and 60 d.Results showed that BA and BS inoculations increased lactic acid concentrations of whole-plant corn silages compared with control,and BA inoculation decreased acetic acid concentrations,whereas BS inoculation decreased fiber contents and increased crude protein(CP)content.Higher water-soluble carbohydrate contents and lower starch contents were observed in BA-and BS-inoculated silages compared with that in control.The decreased CP content and increased non-protein nitrogen content were observed in BA-inoculated silage,which was consistent with the higher amino acid metabolism abundances observed in BA-inoculated silage.In addition,it was noteworthy that BA and BS inoculations increased the metabolism of cofactors and vitamins,and decreased the relative abundances of drug resistance:antimicrobial pathways.We also found that the bacterial metabolism pathways were clearly separated into three clusters based on the ensiling times of whole-plant corn silage in the present study.There were no significant differences in bacterial community compositions among the three groups during ensiling.However,BA and BS inoculations decreased the relative abundances of undesirable bacteria such as Acetobacter and Acinetobacter.Conclusion:Our findings suggested that the BS strain was more suitable as silage inoculants than the BA strain in whole-plant corn silage in this study. | Jie Bai Marcia Franco Zitong Ding Lin Hao Wencan Ke Musen Wang Dongmei Xie Ziqian Li Yixin Zhang Lin Ai Xusheng Guo | 2022 | Journal of Animal Science and Biotechnology2022，13，3： | 5 |
| 3 | Deregulated expression and subcellular localization of CPSF6,a circRNA-binding protein,promote malignant development of esophageal squamous cell carcinoma显示文摘Objective:Cleavage and polyadenylation specific factor 6(CPSF6)has been documented as an oncoprotein in different types of cancer.However,functions of CPSF6 have not been investigated yet in esophageal squamous cell carcinoma(ESCC).Here,we aimed to investigate the potential clinical values and biological functions of CPSF6 in ESCC.Methods:For determining the expression level of CPSF6 in ESCC patients,we analyzed published data,performed quantitative real-time polymerase chain reaction(RT-qPCR)and immunohistochemistry assays.Kaplan-Meier curves and log-rank tests were used for survival analyses.GO and KEGG analyses were done for CPSF6-related genes.Cell proliferation,colony formation and xenograft assays were conducted to verify the effects of CPSF6 on ESCC.In addition,cell cycle and apoptosis assays were also performed to manifest the functions of CPSF6 and circCPSF6.RNA pulldown and radioimmunoprecipitation(RIP)assays were used for confirming the interaction between circCPSF6(hsa_circ_0000417)and CPSF6 protein.The regulatory relationship between CPSF6 protein and circCPSF6 was determined by RT-qPCR.Results:We found that CPSF6 was upregulated in ESCC tissues and overexpression of cytoplasmic CPSF6 was associated with poor prognosis.GO and KEGG analyses suggested that CPSF6 could mainly affect cell division in ESCC.Further experiments manifested that CPSF6 promoted cell proliferation and colony formation in vitro.Xenograft assay showed that knockdown of CPSF6 significantly decreased tumor growth rate in vivo.Subsequently,we verified that depletion of CPSF6 led to cell cycle arrest and apoptosis.Finally,we validated that CPSF6,as a circRNA-binding protein,interacted with and regulated its circular isoform circCPSF6(hsa_circ_0000417),of which depletion also resulted in cell cycle arrest and cell apoptosis in ESCC.Conclusions:These findings gave us insight that overexpression of cytoplasmic CPSF6 protein is associated with poor prognosis in ESCC and CPSF6 may function as an oncoprotein,at least in part,through regulating circCPSF6 expression. | Shichao Guo Guangchao Wang Zitong Zhao Dan Li Yongmei Song Qimin Zhan | 2022 | Chinese Journal of Cancer Research2022，34，1： | 1 |
| 4 | Effects of inoculating feruloyl esterase-producing Lactiplantibacillus plantarum A1 on ensiling characteristics,in vitro ruminal fermentation and microbiota of alfalfa silage显示文摘Background Ferulic acid esterase(FAE)-secreting Lactiplantibacillus plantarum A1(Lp A1)is a promising silage inoculant due to the FAE’s ability to alter the plant cell wall structure during ensiling,an action that is expected to improve forage digestibility.However,little is known regarding the impacts of Lp A1 on rumen microbiota.Our research assessed the influences of Lp A1 in comparison to a widely adopted commercial inoculant Lp MTD/1 on alfalfa’s ensilage,in vitro rumen incubation and microbiota.Results Samples of fresh and ensiled alfalfa treated with(either Lp A1 or Lp MTD/1)or without additives(as control;CON)and ensiled for 30,60 and 90 d were used for fermentation quality,in vitro digestibility and batch culture study.Inoculants treated silage had lower(P<0.001)pH,acetic acid concentration and dry matter(DM)loss,but higher(P=0.001)lactic acid concentration than the CON during ensiling.Compared to the CON and Lp MTD/1,silage treated with Lp A1 had lower(P<0.001)aNDF,ADF,ADL,hemicellulose,and cellulose contents and higher(P<0.001)free ferulic acid concentration.Compared silage treated with Lp MTD/1,silage treated with Lp A1 had significantly(P<0.01)improved ruminal gas production and digestibility,which were equivalent to those of fresh alfalfa.Realtime PCR analysis indicated that Lp A1 inoculation improved the relative abundances of rumen’s total bacteria,fungi,Ruminococcus albus and Ruminococcus flavefaciens,while the relative abundance of methanogens was reduced by Lp MTD/1 compared with CON.Principal component analysis of rumen bacterial 16S rRNA gene amplicons showed a clear distinction between CON and inoculated treatments without noticeable distinction between Lp A1 and Lp MTD/1 treatments.Comparison analysis revealed differences in the relative abundance of some bacteria in different taxa between Lp A1 and Lp MTD/1 treatments.Silage treated with Lp A1 exhibited improved rumen fermentation characteristics due to the inoculant effects on the rumen microbial populations and bacterial community.Conclusions Our findings suggest that silage inoculation of the FAE-producing Lp A1 could be effective in improving silage quality and digestibility,and modulating the rumen fermentation to improve feed utilization. | Fuhou Li Samaila Usman Wenkang Huang Mengya Jia Zohreh Akhavan Kharazian Tao Ran Fadi Li Zitong Ding Xusheng Guo | 2023 | Journal of Animal Science and Biotechnology2023，14，4： | 1 |
| 5 | Repurposed benzydamine targeting CDK2 suppresses the growth of esophageal squamous cell carcinoma显示文摘Esophageal squamous cell carcinoma (ESCC) is one of the leading causes of cancer death worldwide. It is urgent to develop new drugs to improve the prognosis of ESCC patients. Here, we found benzydamine, a locally acting non-steroidal anti-inflammatory drug, had potent cytotoxic effect on ESCC cells. Benzydamine could suppress ESCC proliferation in vivo and in vitro. In terms of mechanism, CDK2 was identified as a target of benzydamine by molecular docking, pull-down assay and in vitro kinase assay. Specifically, benzydamine inhibited the growth of ESCC cells by inhibiting CDK2 activity and affecting downstream phosphorylation of MCM2, c-Myc and Rb, resulting in cell cycle arrest. Our study illustrates that benzydamine inhibits the growth of ESCC cells by downregulating the CDK2 pathway. | Yubing Zhou Xinyu He Yanan Jiang Zitong Wang Yin Yu Wenjie Wu Chenyang Zhang Jincheng Li Yaping Guo Xinhuan Chen Zhicai Liu Jimin Zhao Kangdong Liu Zigang Dong | 2023 | Frontiers of Medicine2023，17，2： | 0 |

| 7 | Study on the Distribution of Frictional Forces on Z-yarn Continuous Implanted Preforms and Their Applications显示文摘To improve the quality and efciency of Z-directional 3D preform forming,the Z-yarn frictional force distribution model of the preform and its wear mechanism were investigated.In this study,a tensile force measuring device was designed to measure the force required to replace the guide sleeve,which is equivalent to the Z-yarn frictional forces.The frictional force is proportional to the number of preform layers and is applied to the preform decreased from the corner,edge,sub-edge,and middle in order.A back propagation neural network model was established to predict the friction at diferent positions of the preform with diferent layers,and the error was within 1.9%.The wear of Z-yarn was studied at diferent frictional positions and after diferent times of successive implantation into the preform.The results showed that with an increase in the number of Z-yarn implantations and frictional forces,the amount of carbon fber bundle hairiness gradually increased,and the tensile fracture strength damage of the fber was increasingly afected by the frictional forces.In the corner position of the preform,when the number of implantations was 25,the fber fracture strength decreased non-linearly and substantially;in order to avoid fber fracturing in the implantation process,the Z-yarn needs to be replaced in time after 20–25 cycles of continuous implantation.This study solves the problem of difculty in measuring the force required for individual replacements owing to the excessive number of guide sleeves,puts forward the relationship between fber wear,preform position,and implantation times,solves the phenomenon of fracture in the preform during Z-direction fber implantation,and realizes the continuous implantation of fbers. | Zitong Guo Zhongde Shan Jihua Huang Debo Xue | 2022 | Chinese Journal of Mechanical Engineering2022，35，4： | 0 |
