2Interferon-armed RBD dimer enhances the immunogenicity of RBD for sterilizing immunity against SARS-CoV-2显示文摘Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)has caused a global crisis,urgently necessitating the development of safe,efficacious,convenient-to-store,and low-cost vaccine options.A major challenge is that the receptor-binding domain(RBD)-only vaccine fails to trigger long-lasting protective immunity if used alone for vaccination.Shiyu Sun Yueqi Cai Tian-Zhang Song Yang Pu Lin Cheng Hairong Xu Jing Sun Chaoyang Meng Yifan Lin Haibin Huang Fang Zhao Silin Zhang Yu Gao Jian-Bao Han Xiao-Li Feng Dan-Dan Yu Yalan Zhu Pu Gao Haidong Tang Jincun Zhao Zheng Zhang Jiaming Yang Zhenxiang Hu Yang-Xin Fu Yong-Tang Zheng Hua Peng 2021Cell Research2021,31,9:7
3Effectiveness of Inactivated COVID-19 Vaccines Against Symptomatic,Pneumonia,and Severe Disease Caused by the Delta Variant:Real World Study and Evidence—China,2021显示文摘Summary What is already known about this topic?Effectiveness of China’s 2 inactivated vaccines(BBIBPCorV and CoronaVac)against pre-Delta severe acute respiratory syndrome coronavirus-2(SARS-CoV-2)variants ranged from 47%to over 90%,depending on the clinical endpoint,and with greater effectiveness against more severe coronavirus disease 2019(COVID-19).During an outbreak in Guangdong,inactivated vaccine effectiveness(VE)against the Delta variant was 70%for symptomatic infection and 100%for severe COVID-19.However,separate or combined VE estimates for the two inactivated vaccines against Delta are not available.What is added by this report?In an outbreak that started in a hospital,VEs of completed primary vaccination with inactivated COVID-19 vaccines against symptomatic COVID-19,COVID-19 pneumonia,and severe COVID-19 caused by the Delta variant were 51%,61%,and 82%.Completed primary vaccination reduced the risk of progressing from mild to moderate or severe COVID-19 by 74%.VE estimates for BBIBP-CorV and CoronaVac or combined vaccination were similar,and partial vaccination was ineffective.What are the implications for public health practice?Completed primary vaccination with either of the 2 inactivated COVID-19 vaccines reduces risk of symptomatic COVID-19,COVID-19 pneumonia,and severe COVID-19 caused by the Delta variant.Completion of the completed primary vaccination with two doses is necessary for protection from Delta.Dan Wu Yanyang Zhang Lin Tang Fuzhen Wang Ying Ye Chao Ma Hui Zheng Wenzhou Yu Lei Cao Yifan Song Abuduwaili Reyimu Xiaoxiao Zhang Haifeng Wang Yifei Nie Mingxia Lu Muge Qi Jun Li Ruolin Wang Kaichao Yang Changshuang Wang Lawrence Everett Rodewald Geroge Fu Gao Zhijie An Zundong Yin 2022China CDC weekly2022,4,4:7
4Transformers in computational visual media:A survey显示文摘Transformers,the dominant architecture for natural language processing,have also recently attracted much attention from computational visual media researchers due to their capacity for long-range representation and high performance.Transformers are sequence-to-sequence models,which use a selfattention mechanism rather than the RNN sequential structure.Thus,such models can be trained in parallel and can represent global information.This study comprehensively surveys recent visual transformer works.We categorize them according to task scenario:backbone design,high-level vision,low-level vision and generation,and multimodal learning.Their key ideas are also analyzed.Differing from previous surveys,we mainly focus on visual transformer methods in low-level vision and generation.The latest works on backbone design are also reviewed in detail.For ease of understanding,we precisely describe the main contributions of the latest works in the form of tables.As well as giving quantitative comparisons,we also present image results for low-level vision and generation tasks.Computational costs and source code links for various important works are also given in this survey to assist further development.Yifan Xu Huapeng Wei Minxuan Lin Yingying Deng Kekai Sheng Mengdan Zhang Fan Tang Weiming Dong Feiyue Huang Changsheng Xu 2022Computational Visual Media2022,8,1:6
5MS1 is essential for male fertility by regulating the microsporocyte cell plate expansion in soybean显示文摘Male sterility is an essential trait in hybrid seed production,especially for monoclinous and autogamous food crops.Soybean male-sterile ms1 mutant has been known for more than 50 years and could be instrumental in making hybrid seeds.However,the gene responsible for the male-sterile phenotype has remained unknown.Here,we report the map-based cloning and characterization of the MS1 gene in soybean.MS1 encodes a kinesin protein and localizes to the nucleus,where it is required for the male meiotic cytokinesis after telophase Ⅱ.We further substantiated that MS1 colocalizes with microtubules and is essential for cell plate formation in soybean male gametogenesis through immunostaining.Both ms1 and CRISPR/Cas9 knockout mutants show complete male sterility but are otherwise phenotypically normal,making them perfect tools for producing hybrid seeds.The identification of MS1 has the practical potential for assembling the sterility system and speeding up hybrid soybean breeding.Xiaolong Fang Xiaoyuan Sun Xiangdong Yang Qing Li Chunjing Lin Jie Xu Wenjun Gong Yifan Wang Lu Liu Limei Zhao Baohui Liu Jun Qin Mengchen Zhang Chunbao Zhang Fanjiang Kong Meina Li 2021Science China(Life Sciences)2021,64,9:4

7Tailoring the Meso-Structure of Gold Nanoparticles in Keratin-Based Activated Carbon Toward High-Performance Flexible Sensor显示文摘Flexible biosensors with high accuracy and reliable operation in detecting pH and uric acid levels in body fluids are fabricated using well-engineered metaldoped porous carbon as electrode material.The gold nanoparticles@N-doped carbon in situ are prepared using wool keratin as both a novel carbon precursor and a stabilizer.The conducting electrode material is fabricated at 500℃ under customized parameters,which mimics A-B type(two different repeating units) polymeric material and displays excellent deprotonation performance(pH sensitivity).The obtained pH sensor exhibits high pH sensitivity of 57 mV/pH unit and insignificant relative standard deviation of 0.088%.Conversely,the composite carbon material with sp^2 structure prepared at 700℃ is doped with nitrogen and gold nanoparticles,which exhibits good conductivity and electrocatalytic activity for uric acid oxidation.The uric acid sensor has linear response over a range of 1-150 μM and a limit of detection 0.1 μM.These results will provide new avenues where biological material will be the best start,which can be useful to target contradictory applications through molecular engineering at mesoscale.Aniruddha BPatil Zhaohui Meng Ronghui Wu Liyun Ma Zijie Xu Chenyang Shi Wu Qiu Qiang Liu Yifan Zhang Youhui Lin Naibo Lin Xiang Yang Liu 2020Nano-Micro Letters2020,12,9:3
8Antigenicity of tissues and organs from GGTA1/CMAH/β4GalNT2 triple gene knockout pigs显示文摘Clinical xenotransplantations have been hampered by human preformed antibody-mediated damage of the xenografts.To overcome biological incompatibility between pigs and humans,one strategy is to remove the major antigens[Gal,Neu5 Gc,and Sd(a)]present on pig cells and tissues.Triple gene(GGTAI,CMAH,and β4 GalNT2)knockout(TKO)pigs were produced in our laboratory by CRISPR-Cas9 targeting.To investigate the antigenicity reduction in the TKO pigs,the expression levels of these three xenoantigens in the cornea,heart,liver,spleen,lung,kidney,and pancreas tissues were examined.The level of human IgG/IgM binding to those tissues was also investigated,with wildtype pig tissues as control.The results showed that aGal,Neu5 Gc,and Sd(a)were markedly positive in all the examined tissues in wildtype pigs but barely detected in TKO pigs.Compared to wildtype pigs,the liver,spleen,and pancreas of TKO pigs showed comparable levels of human IgG and IgM binding,whereas corneas,heart,lung,and kidney of TKO pigs exhibited significantly reduced human IgG and IgM binding.These results indicate that the antigenicity of TKO pig is significantly reduced and the remaining xenoantigens on porcine tissues can be eliminated via a gene targeting approach.Ronggen Wang Miaomiao Ruan Runjie Zhang Lei Chen Xiaoxue Li Bin Fang Chu Li Xueyang Ren Jiying Liu Qiang Xiong Lining Zhang Yong Jin Lin Li Rongfeng Li Ying Wang Haiyuan Yang Yifan Dai 2019The Journal of Biomedical Research2019,33,4:3
9Output of an Ultrasonic Wave-Driven Nanogenerator in a Confi ned Tube显示文摘The output of an ultrasonic wave-driven nanogenerator(NG)has been found to depend on the excitation conditions and geometry.Incidence angle tests indicate that the effective area of an NG determines the amount of power that can be generated.The output power of an NG is also directly related to its distance from the ultrasonic source.A sinusoidal profile of the electrical output was observed when an NG was moved inside a long tube filled with water with the ultrasonic source located at one end.This is due to the oscillation of the wave intensity inside the tube as a function of the distance from the excitation source.Xudong Wang Yifan Gao Yaguang Wei Zhong Lin Wang 2009Nano Research2009,2,3:3
10Nampt is involved in DNA double-strand break repair显示文摘DNA double-strand break(DSB) is the most severe form of DNA damage,which is repaired mainly through high-fidelity homologous recombination(HR) or error-prone non-homologous end joining(NHEJ).Defects in the DNA damage response lead to genomic instability and ultimately predispose organs to cancer.Nicotinamide phosphoribosyltransferase(Nampt),which is involved in nicotinamide adenine dinucleotide metabolism,is overexpressed in a variety of tumors.In this report,we found that Nampt physically associated with CtIP and DNA-PKcs/Ku80,which are key factors in HR and NHEJ,respectively.Depletion of Nampt by small interfering RNA(siRNA) led to defective NHEJ-mediated DSB repair and enhanced HR-mediated repair.Furthermore,the inhibition of Nampt expression promoted proliferation of cancer cells and normal human fibroblasts and decreased β-galactosidase staining,indicating a delay in the onset of cellular senescence in normal human fibroblasts.Taken together,our results suggest that Nampt is a suppressor of HR-mediated DSB repair and an enhancer of NHEJ-mediated DSB repair,contributing to the acceleration of cellular senescence.Bingtao Zhu Xiaoli Deng Yifan Sun Lin Bai Zhikai Xiahou Yusheng Cong Xingzhi Xu 2012Chinese Journal of Cancer2012,31,8:2
11Frequency-domain analysis of computer-controlled optical surfacing processes显示文摘Mid-high spatial frequency errors are often induced on optical surfaces polished by computer-controlled optical surfacing (CCOS) processes. In order to efficiently remove these errors, which would degrade the performances of optical systems, the ability of a CCOS process to correct the errors have been investigated based on the convolution integral model in view of the availability of material removal. To quantify the ability, some conceptions, such as figure correcting ability and material removal availability (MRA), have been proposed. The research result reveals that the MRA of the CCOS process to correct a single spatial frequency error is determined by its tool removal function (TRF), and it equals the normalized amplitude spectrum of the Fourier transform of its TRF. Finally, three sine surfaces were etched using ion beam figuring (IBF), which is a typical CCOS process. The experimental results have verified the theoretical analysis. The employed method and the conclusions of this work provide a useful mathematical basis to analyze and optimize CCOS processes.ZHOU Lin DAI YiFan XIE XuHui LI ShengYi 2009Science China(Technological Sciences)2009,52,7:2
12Deep Learning in Sheet Metal Bending With a Novel Theory-Guided Deep Neural Network显示文摘Sheet metal forming technologies have been intensively studied for decades to meet the increasing demand for lightweight metal components.To surmount the springback occurring in sheet metal forming processes,numerous studies have been performed to develop compensation methods.However,for most existing methods,the development cycle is still considerably time-consumptive and demands high computational or capital cost.In this paper,a novel theory-guided regularization method for training of deep neural networks(DNNs),implanted in a learning system,is introduced to learn the intrinsic relationship between the workpiece shape after springback and the required process parameter,e.g.,loading stroke,in sheet metal bending processes.By directly bridging the workpiece shape to the process parameter,issues concerning springback in the process design would be circumvented.The novel regularization method utilizes the well-recognized theories in material mechanics,Swift’s law,by penalizing divergence from this law throughout the network training process.The regularization is implemented by a multi-task learning network architecture,with the learning of extra tasks regularized during training.The stress-strain curve describing the material properties and the prior knowledge used to guide learning are stored in the database and the knowledge base,respectively.One can obtain the predicted loading stroke for a new workpiece shape by importing the target geometry through the user interface.In this research,the neural models were found to outperform a traditional machine learning model,support vector regression model,in experiments with different amount of training data.Through a series of studies with varying conditions of training data structure and amount,workpiece material and applied bending processes,the theory-guided DNN has been shown to achieve superior generalization and learning consistency than the data-driven DNNs,especially when only scarce and scattered experiment data are available for training which is often the case in practice.The theory-guided DNN could also be applicable to other sheet metal forming processes.It provides an alternative method for compensating springback with significantly shorter development cycle and less capital cost and computational requirement than traditional compensation methods in sheet metal forming industry.Shiming Liu Yifan Xia Zhusheng Shi Hui Yu Zhiqiang Li Jianguo Lin 2021IEEE/CAA Journal of Automatica Sinica2021,8,3:2
13Effect of oxymatrine on interferon-gamma and tumor necrosis factor-alpha serum levels in an experimental rat model of autoimmune encephalomyelitis显示文摘BACKGROUND:Studies have demonstrated that experimental autoimmune encephalomyelitis(EAE) onset correlates with increased interferon-γ(IFN-γ) and tumor necrosis factor-α(TNF-α) expression.Oxymatrine(OM) has been shown to inhibit autoimmune responses,but there are no reports showing that it could prevent the development of EAE.OBJECTIVE:To observe the effect of OM on serum levels of IFN-γ and TNF-α in a rat model of EAE.DESIGN,TIME AND SETTING:A randomized,controlled,animal study was performed at the Experimental Animal Center of Henan Academy of Chinese Medicine and at the Key Disciplines Laboratory Clinical Medicine of Henan Province between July and December 2008.MATERIALS:OM was purchased from Chia-tai Tianqing Pharmaceutical,China;complete Freund's adjuvant was purchased from Sigma,USA.METHODS:Forty female Wistar rats were randomly assigned to four groups:EAE model(M),low-dose OM treatment(OM-L),high-dose OM treatment(OM-H),and normal control(N,no immunization),with 10 rats in each group.EAE was established in the M,OM-L,and OM-H groups following immunization with Guinea pig spinal cord homogenate and complete Freund's adjuvant.The M and N groups were intraperitoneally injected with normal saline(6.7 mL/kg per day),the OM-L group received an intraperitoneal injection of OM(100 mg/kg per day),and the OM-H group received OM(150 mg/kg per day).MAIN OUTCOME MEASURES:At 16 days after immunization,the degree of histopathological changes in the spinal cord was assessed by hematoxylin-eosin stanining.Enzyme-linked immunosorbent assay was used to detect serum levels of IFN-γ,and radioimmunoassay was utilized to determine serum TNF-α level.Neurological scores were measured on a daily basis according to a 0-5 scale.RESULTS:Daily injections of OM,both high and low doses,resulted in decreased neurological scores in EAE rats(P < 0.01),as well as reduced cellular infiltration in the spinal cord and decreased levels of serum IFN-γ and TNF-α(P < 0.01).CONCLUSION:OM reduced the onset and severity of EAE,which correlated with decreased IFN-γ and TNF-α expression.Xiaobin Guo Quancheng Kan Yifan Song Lin Zhu Xiang Li Haiying Hua GuangxianZhang 2010Neural Regeneration Research2010,5,10:2
14Overexpressing dominant-negative FGFR2-IIIb impedes lung branching morphogenesis in pigs显示文摘Genetic studies with mouse models have shown that fibroblast growth factor receptor 2-IIIb(FGFR2-IIIb)plays crucial roles in lung development and differentiation. To evaluate the effect of FGFR2-IIIb in pig lung development, we employed somatic cell nuclear transfer(SCNT) technology to generate transgenic pig fetuses overexpressing the transmembrane(dn FGFR2-IIIb-Tm) and soluble(dn FGFR2-IIIb-HFc) forms of the dominant-negative human FGFR2-IIIb driven by the human surfactant protein C(SP-C) promoter,which was specifically expressed in lung epithelia. Eight dn FGFR2-IIIb-Tm transgenic and twelve dn FGFR2-IIIb-HFc transgenic pig fetuses were collected from three and two recipient sows, respectively.Repression of FGFR2-IIIb in lung epithelia resulted in smaller lobes and retardation of alveolarization in both forms of dn FGFR2-IIIb transgenic fetuses. Moreover, the dn FGFR2-IIIb-HFc transgenic ones showed more deterioration in lung development. Our results demonstrate that disruption of FGFR2-IIIb signaling in the epithelium impedes normal branching and alveolarization in pig lungs, which is less severe than the results observed in transgenic mice. The dn FGFR2-IIIb transgenic pig is a good model for the studies of blastocyst complementation as well as the mechanisms of lung development and organogenesis.Qin Chen Bin Fang Ying Wang Chu Li Xiaoxue Li Ronggen Wang Qiang Xiong Lining Zhang Yong Jin Manling Zhang Xiaorui Liu Lin Li Lisha Mou Rongfeng Li Haiyuan Yang Yifan Dai 2018Journal of Genetics and Genomics2018,45,3:2
15A Bama miniature pig model of monoallelic TSC1 mutation for human tuberous sclerosis complex显示文摘Tuberous sclerosis complex(TSC)is a dominant genetic neurocutaneous syndrome characterized by multiple organ hamartomas.Although rodent models bearing a germline mutation in either TSC1 or TSC2 gene have been generated,they do not develop pathogenic lesions matching those seen in patients with TSC because of the significant differences between mice and humans,highlighting the need for an improved large animal model of TSC.Here,we successfully generate monoallelic TSC1-modified Bama miniature pigs using the CRISPR/Cas9 system along with somatic cell nuclear transfer(SCNT)technology.The expression of phosphorylated target ribosomal protein S6 is significantly enhanced in the piglets,indicating that disruption of a TSC1 allele activate the mechanistic target of rapamycin(mTOR)signaling pathway.Notably,differing from the mouse TSC models reported previously,the TSC1^(+/−)Bama miniature pig developed cardiac rhabdomyoma and subependymal nodules,resembling the major clinical features that occur in patients with TSC.These TSC1^(+/−)Bama miniature pigs could serve as valuable large animal models for further elucidation of the pathogenesis of TSC and the development of therapeutic strategies for TSC disease.Xiaoxue Li Tingdong Hu Jiying Liu Bin Fang Xue Geng Qiang Xiong Lining Zhang Yong Jin Xiaorui Liu Lin Li Ying Wang Rongfeng Li Xiaochun Bai Haiyuan Yang Yifan Dai 2020Journal of Genetics and Genomics2020,47,12:2
16Influence of traffic on the temperature field of tunnel in cold region:A case study on the world’s longest highway spiral tunnel显示文摘The impact of the piston wind caused by vehicle traffic on the temperature field distribution of the tunnel cannot be ignored,especially in spiral tunnels,where the temperature field distribution is more complicated than that in straight tunnels.Based on the world’s longest highway spiral tunnel,this study explores the influence of traffic on the temperature fields of spiral and straight tunnels,and proposes a new design method for laying length of insulation layer.The results show that traffic has a significant effect on the temperature field dis-tribution in the tunnel.The influence degree of different traffic elements decreases in the following order:average vehicle speed>daily traffic>morning rush hour>evening rush hour.The temperature field distribution of spiral tunnels is asymmetry on the left and right compared with straight tunnels,while the influence degree of traffic on the outside of spiral tunnels is similar to that of straight tunnels.Due to the difference of wind direction and traffic direction at different tunnel openings,an asymmetric insulation layer laying method is proposed.It is suggested that the lengths of the insulation layers of the Jinjiazhuang Tunnel should be 1200 m for the right tunnel inlet,700 m for the right tunnel outlet,700 m for the left tunnel inlet,and 1400 m for the left tunnel outlet.Yifan Jiang Jianyou Yu Ping Zhou Feicong Zhou Jiayong Lin Jinyi Li Ming Lin Feiya Lei Zhijie Wang 2023Underground Space2023,,1:2
17Visual quality of juvenile myopes wearing multifocal soft contact lenses显示文摘Background:It is unclear whether multifocal soft contact lenses(MFSCLs)affect visual quality when they are used for myopia control in juvenile myopes.The aim of this study was,therefore,to investigate the effect of MFSCLs on visual quality among juvenile myopia subjects.Methods:In a prospective,intervention study,thirty-three juvenile myopes were enrolled.Visual perception was assessed by a quality of vision(QoV)questionnaire with spectacles at baseline and after 1 month of MFSCL wear.At the one-month visit,the high(96%)contrast distance visual acuity(distance HCVA)and low(10%)contrast distance visual acuity(distance LCVA)were measured with single vision spectacle lenses,single vision soft contact lenses(SVSCLs)and MFSCLs in a random order.Wavefront aberrations were measured with SVSCLs,with MFSCLs,and without any correction.Results:Neither distance HCVA(p>0.05)nor distance LCVA(p>0.05)revealed any significant difference between MFSCLs,SVSCLs and single vision spectacle lenses.The overall score(the sum of ten symptoms)of the QoV questionnaire did not show a statistically significant difference between spectacles at baseline and after 1 month of MFSCL wear(p=0.357).The results showed that the frequency(p<0.001),severity(p=0.001)and bothersome degree(p=0.016)of halos were significantly worse when wearing MFSCLs than when wearing single vision spectacle lenses.In contrast,the bothersome degree caused by focusing difficulty(p=0.046)and the frequency of difficulty in judging distance or depth perception(p=0.046)were better when wearing MFSCLs than when wearing single vision spectacle lenses.Compared with the naked eye,MFSCLs increased the total aberrations(p<0.001),higher-order aberrations(p<0.001),trefoil(p=0.023),coma aberrations(p<0.001)and spherical aberrations(SA)(p<0.001).Compared with the SVSCLs,MFSCLs increased the total aberrations(p<0.001),higher-order aberrations(p<0.001),coma aberrations(p<0.001)and SA(p<0.001).The direction of SA was more positive(p<0.001)with the MFSCLs and more negative(p=0.001)with the SVSCLs compared with the naked eye.Conclusions:Wearing MFSCLs can provide satisfactory corrected visual acuity(both distance HCVA and distance LCVA).Although the lenses increased the aberrations,such as total aberrations and higher-order aberrations,there were few adverse effects on the distance HCVA,distance LCVA and visual perception after 1 month of MFSCL use.Xiaopeng Huang Feifu Wang Zhiyi Lin Yifan He Shuyun Wen Ling Zhou Fan Lu Jun Jiang 2020Eye and Vision2020,7,1:2
18Recent progress in functionalized layered double hydroxides and their application in efficient electrocatalytic water oxidation显示文摘Layered double hydroxides (LDHs), a class of anionic clays consisting of brucite-like host layers and interlayer anions, have been widely investigated in the last decade due to their promising applications in many areas such as catalysis, ion separation and adsorption. Owing to the highly tunable compositi on and uniform distribution of metal cations in the brucite-like layers, as well as the facile exchangeability of intercalated anions, LDHs can be modified and functionalized to form various nanostructures/composites through versatile processes such as anion intercalation and exfoliation, decoration of nanoparticles, selfassembly with other two-dimensional (2D) materials, and controlled growth on conductive supports (e.g., nanowire arrays, nano tubes, 3D foams). In this article, we briefly review the recent advances on both the LDH nano structures and functionalized composites toward the applications in energy conversion, especially for water oxidation.Xiaolong Deng Jinzhao Huang Hao Wan Fashen Chen Yifan Lin Xijin Xu Renzhi Ma Takayoshi Sasaki 2019Journal of Energy Chemistry2019,28,5:2
19Association of human leukocyte antigen-DR-DQ-DP haplotypes with the risk of hepatitis B virus-related hepatocellular carcinoma显示文摘Aim:Genetic polymorphisms of human leukocyte antigen(HLA)class II molecules are associated with chronic hepatitis B virus(HBV)infection.We aimed to investigate the impacts of HLA-II haplotypes on viral evolution and the risks of HBV-caused liver diseases.Methods:HLA-DR-DQ-DP haplotypes were estimated in 1210 healthy controls,296 HBV clearance subjects,301 asymptomatic hepatitis B surface antigen carriers,770 chronic hepatitis B patients,443 HBV-related liver cirrhosis(LC)patients,and 1037 HBV-related hepatocellular carcinoma(HCC)patients.HBV mutations were determined by sequencing.The associations of HLA-DR-DQ-DP haplotypes with viral mutations and the risks of liver diseases were assessed by multivariate logistic regression.Results:Compared to HBV-free subjects,the haplotypes CCAACG,CCGACG,TCAATA,and TCGATA were associated with decreased HCC risk,with an odds ratio(OR)[95%confidence interval(CI)]of 0.62(0.40-0.95),0.60(0.39-0.92),0.73(0.54-0.98),and 0.58(0.42-0.78),respectively.CCAACG,CCGACG,and TCAATA were significantly associated with decreased frequencies of the HCC-risk HBV mutations:preS1 deletion,APOBECsignature HBV mutations in the core promoter and preS regions,A51C/T,G104C/T,and G146C/T.TCGATA and TTAACG were associated with increased LC risk,with an OR(95%CI)of 1.54(1.03-2.30)and 2.23(1.50-3.33),respectively.However,TCGATA and TTAACG were not consistently associated with the cirrhosis-risk HBV mutations.Conclusion:CCAACG,CCGACG,and TCAATA are inversely associated with HCC risk,possibly because they are involved in creating an immune microenvironment attenuating the generation of HCC-risk HBV mutations.TCGATA and TTAACG might predispose the polarity of immunity towards Th17 isotype related to LC.Yifan Chen Jiansheng Lin Yang Deng Wenbin Liu Zishuai Li Xinyu Zhou Shiliang Cai Rui Pu Jianhua Yin Xiaojie Tan Jun Zhao Xue Han Guangwen Cao 2022Hepatoma Research2022,8,1:2
20Unbalanced omega-6/omega-3 ratio in red meat products in China显示文摘Dietary meats play a crucial role in human health.The objective of this survey was to determine the fatty acid content and omega-6/omega-3 polyunsaturated fatty acids(n-6/n-3 PUFA)ratio of fresh red meat(beef and pork)from four cities(Shanghai,Nanjing,Yinchuan and Hohhot)in China.The results showed that the n-6/n-3 PUFA ratio from all the samples ranged from 6 to 23.The total n-6 PUFA concentrations ranged from 290.54 mg/100g in beef from Nanjing to 1601.48 mg/100 g in pork from Hohhot,whereas the total concentrations of n-3 PUFA ranged from 46.34 mg/100 g in beef from Nanjing to 96.03 mg/100 g in pork from Nanjing.The results indicated that the n-6/n-3 ratio in the red meat from all four regions is unbalanced and is much higher than that(<5:1)recommended by the WHO/FAO.The total amount of n-3 PUFA was far lower than the required daily dose.Therefore,potential solutions to increase the n-3 PUFA content in meat products or to provide alternative source of n-3PUFA should be explored.Ming Yu Qianqian Gao Yan Wang Wei Zhang Lin Li Ying Wang Yifan Dai 2013The Journal of Biomedical Research2013,27,5:2
