| 1 | Effects of dietary supplementation of Artemisia argyi aqueous extract on antioxidant indexes of small intestine in broilers显示文摘The present study was conducted to investigate the effect of Artemisia argyi aqueous extract(AAE) on antioxidant indexes in the small intestine. A total of 192 Arbor Acre broiler chickens(one-day-old) were randomly divided into 4 treatments with 6 replicates of 8 chickens. These 4 diets were formulated by adding 0, 500,1,000 and 2,000 mg/kg AAE to the basal diet. The results showed as follows: 1) compared with the control, the total antioxidant capacity(T-AOC) in ileum for the 2,000 mg/kg treatment group was significantly increased at 21 days of age(P < 0.05); the T-AOC levels in jejunum and ileum were significantly increased in broilers supplemented with 500 mg/kg AAE at 42 days of age(P < 0.05), and the T-AOC levels in jejunum and ileum were significantly improved in 1,000 mg/kg treatment group(P < 0.01), 2) At 21 days of age, supplementation of 500 mg/kg AAE significantly increased the catalase(CAT) activity of small intestine, and the glutathione peroxidase(GSH-Px) activity of jejunum was improved(P < 0.01), meanwhile, the GSH-Px activity of duodenum and the total superoxide dismutase(T-SOD) activity of duodenum and jejunum were significantly higher than those of the control group(P < 0.05); supplementation of 1,000 mg/kg AAE significantly increased the CAT activity of duodenum and ileum and the GSH-Px activity of duodenum and jejunum(P < 0.05), and the ileum GSH-Px activity was significantly increased(P < 0.01); supplementation of 2,000 mg/kg AAE significantly increased the CAT activity of duodenum and ileum(P < 0.05). At 42 days of age, supplementation of 500 mg/kg AAE significantly increased the GSH-Px activity of ileum and the T-SOD activity of duodenum(P < 0.05),meanwhile, the T-SOD activity of jejunum was significantly increased(P < 0.01); supplementation of1,000 mg/kg AAE significantly increased the CAT activity of jejunum and the T-SOD activity of ileum(P < 0.01), and the GSH-Px activity of jejunum was significantly increased(P < 0.05); supplementation of2,000 mg/kg AAE significantly increased the T-SOD activity of ileum(P < 0.05), but significantly decreased the CAT activity of ileum and the GSH-Px activity of jejunum(P < 0.05). 3) The malondialdehyde(MDA) levels of 3 AAE supplementation groups were significantly decreased at 21 and 42 days of age(P < 0.05). The results suggested that dietary supplementation with AAE could improve the antioxidative capacity of small intestine in broilers. | Fei Zhao Binlin Shi Dengsheng Sun Hongyan Chen Manman Tong Pengfei Zhang Xiaoyu Guo Sumei Yan | 2016 | Animal Nutrition2016，，3： | 18 |
| 2 | Sleep Deprivation Selectively Down-Regulates Astrocytic 5-HT2B Receptors and Triggers Depressive-Like Behaviors via Stimulating P2X7 Receptors in Mice显示文摘Chronic loss of sleep damages health and disturbs the quality of life.Long-lasting sleep deprivation(SD)as well as sleep abnormalities are substantial risk factors for major depressive disorder,although the underlying mechanisms are not clear.Here,we showed that chronic SD in mice promotes a gradual elevation of extracellular ATP,which activates astroglial P2X7 receptors(P2X7Rs).Activated P2X7Rs,in turn,selectively down-regulated the expression of 5-HT2B receptors(5-HT2BRs)in astrocytes.Stimulation of P2X7Rs induced by SD selectively suppressed the phosphorylation of AKT and FoxO3 a in astrocytes,but not in neurons.The overexpression of FoxO3a in astrocytes inhibited the expression of 5-HT2BRs.Down-regulation of 5-HT2BsRs instigated by SD suppressed the activation of STAT3 and relieved the inhibition of Ca2+-dependent phospholipase A2.This latter cascade promoted the release of arachidonic acid and prostaglandin E2.The depression-like behaviors induced by SD were alleviated in P2X7R-KO mice.Our study reveals the mechanism underlying chronic SD-induced depression-like behaviors and suggests 5-HT2BRs as a key target for exploring therapeutic strategies aimed at the depression evoked by sleep disorders. | Maosheng Xia Zexiong Li Shuai Li Shanshan Liang Xiaowei Li Beina Chen Manman Zhang Chengyi Dong Alexei Verkhratsky Dawei Guan Baoman Li | 2020 | Neuroscience Bulletin2020，36，11： | 10 |
| 3 | 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 |
| 4 | Microbial community structure and diversity in deep-sea hydrothermal vent sediments along the Eastern Lau Spreading Centre显示文摘The aim of this study is to investigate microbial structures and diversities in five active hydrothermal fields' sediments along the Eastern Lau Spreading Centre (ELSC) in the Lau Basin (southwest Pacific). Microbial communities were surveyed by denatured gradient gel electrophoresis (DGGE) and clone library analysis of 16S rRNA genes. The differences in microbial community structures among sediment samples from the five deep-sea hydrothermal sites were revealed by DGGE profiles. Cluster analysis of DGGE profiles separated the five hydrothermal samples into two groups. Four different 16S rRNA gene clone libraries, representing two selected hydrothermal samples (19-4TVG8 and 19-4TVG11), were constructed. Twenty-three and 32 phylotypes were identified from 166 and 160 bacterial clones respectively, including Proteobacteria, Bacteroidetes, Firmicutes, Nitrospirae and Planctomycetes. The phylum Proteobacteria is dominant in both bacterial libraries with a predominance of Gamma-Proteobacteria. A total of 31 and 25 phylotypes were obtained from 160 and 130 archaeal clones respectively, including Miscellaneous Crenarchaeotic Group, Marine Group Ⅰ and Ⅲ, Marine Benthic Group E, Terrestrial Hot Spring Crenarchaeota and Deep-sea Hydrothermal Vent Euryarchaeota. These results show a variety of clones related to those involved in sulfur cycling, suggesting that the cycling and utilization of sulfur compounds may extensively occur in the Lau Basin deep-sea hydrothermal ecosystem. | WEI Manman ZHANG Rubing WANG Yuguang JI Houguo ZHENG Jia CHEN Xinhua ZHOU Hongbo | 2013 | Acta Oceanologica Sinica2013，32，2： | 6 |

| 6 | Application of multi-stage dynamic magnetizing roasting technology on the utilization of cryptocrystalline oolitic hematite:A review显示文摘A large number of studies have shown that oolitic hematite is an iron ore that is extremely difficult to utilize because of its fine disseminated particle size, high harmful impurity content and oolitic structure.To recover iron from oolitic hematite, we developed a novel multistage dynamic magnetizing roasting technology. Compared with traditional magnetizing roasting technologies, this novel technology has the following advantages: firstly, the oolitic hematite is dynamically reduced in a multi-stage roasting furnace, which shortens the reduction time and avoids ringing and over-reduction;secondly, the novel dynamic magnetizing roasting technology has strong raw material adaptability, and the size range of raw materials can be as wide as 0–15 mm;thirdly, the roasting furnace adopts a preheating-heating process, and the low-calorific value blast furnace gas can be used as the fuel and reductant, which greatly reduces the cost. The actual industrial production data showed that the energy consumption in the roasting process can be less than 35 kg of standard coal per ton of raw ore. The iron grade of the concentrate and iron recovery reached 65% and 90%, respectively. | Hanquan Zhang Pengfei Zhang Feng Zhou Manman Lu | 2022 | International Journal of Mining Science and Technology2022，32，4： | 4 |
| 7 | Which Inspection Approach Is Better to Prevent Drug Fraud: Announced or Unannounced?显示文摘In recent years,there are many crimes related drug fraud occuring in China and many experts think that the main cause is that China Food and Drug Administration (CFDA)adopts announced inspection (AI).In order to circumvent this difficulty,CFDA has exploited unannounced inspection (UI)since 2014.In this paper,the authors study the problem of which one performs better, AI or UI.Specifically,the authors consider a supervisor,which decides the inspection approach,inspection strength and punishment to force the firm to put self-inspection effort to meet the requirements of Good Manufacturing Practice,and a firm,which produces a drug and decides its self-inspection effort. The authors use game theory to model this problem,characterize the equilibrium policies under AI, and compare the effects of the two approaches on preventing drug fraud under complete and incomplete information.The results show that under the complete information,UI performs better if the firm's technical level and the inspection cost are low and AI performs better otherwise.When the supervisor doesn't know the firm's technical level,if the low technical level is high,AI performs better.Otherwise, UI performs better if the inspection cost is low and AI performs better if the inspection cost is high. | ZHANG Manman ZHANG Juliang CHENG T.C.E.

| 8 | Mechanisms of traditional Chinese medicines in the treatment of allergic rhinitis using a network biology approach显示文摘Objective:To systematically explore the effect and mechanism of traditional Chinese herbs in the treatment of allergic rhinitis.Methods:Magnolia flower,xanthium fruit,astragalus root,paniculate cynanchum,scutellaria root,cicada molting,stephania root,small centipeda herb,and licorice root as traditional Chinese herbs are widely used to treat allergic rhinitis.With multiple database integration and entity grammar systems,a molecular interaction network of traditional Chinese herbs for treating allergic rhinitis was established.Bioinformatics approaches were adopted to integrate relevant data and biological information by multiple databases.Molecular interaction network of Chinese herbs for treating allergic rhinitis was constructed based on entity grammar systems model.The network was then used for elucidating the antiallergic rhinitis mechanism of the Chinese herbs on the molecular level.The subnetworks were also extracted to explicitly display the pathway and targets where effective components acted on.Results:Traditional Chinese herbs could influence various pathological aspects in allergic rhinitis including the production of pro-inflammatory substances,such as histamine and cytokine interleukin-4(IL-4),interleukin-13(IL-13),lowering immunoglobulin E(IgE)level or blocking antigen binding,altering the biological processes of IgE,modulating the balance of T helper(Th)or other cells by cell proliferation and differentiation,mediating cellecell signaling and second-messenger-mediated signaling,stabilizing the cell membrane,and affecting regulation of cellular defense response.Conclusion:The research theoretically confirms the mechanism of anti-allergic rhinitis by traditional Chinese herbs,provides important fundamental research information for treatment of allergic rhinitis,and may serve as a reference for new drug development and effective ingredients of compatibility. | Li Du Xiaotong Ye Manman Li Huihui Wang Baixia Zhang Rao Zheng Yun Wang | 2021 | Journal of Traditional Chinese Medical Sciences2021，8，1： | 3 |
| 9 | AFF3-DNA methylation interplay in maintaining the mono-allelic expression pattern of XIST in terminally differentiated cells显示文摘X chromosome inactivation and genomic imprinting are two classic epigenetic regulatory processes that cause mono-allelic gene expression.In female mammals,mono-allelic expression of the long non-coding RNA gene X-inactive specific transcript(XIST)is essential for initiation of X chromosome inactivation upon differentiation.We have previously demonstrated that the central factor of super elongation complex-like 3(SEC-L3),AFF3,is enriched at gamete differentially methylated regions(DMRs)of the imprinted loci and regulates the imprinted gene expression.Here,we found that AFF3 can also bind to the DMR downstream of the XIST promoter.Knockdown of AFF3 leads to de-repression of the inactive allele of X IST in terminally differentiated cells.In addition,the binding of AFF3 to the XIST DMR relies on DNA methylation and also regulates DNA methylation level at DMR region.However,the KAP1-H3K9 methylation machineries,which regulate the imprinted loci,might not play major roles in maintaining the mono-aUelic expression pattern of XIST in these cells.Thus,our results suggest that the differential mechanisms involved in the X IST DMR and gDMR regulation,which both require AFF3 and DNA methylation. | Yue Zhang Chao Wang Xiaoxu Liu Qian Yang Hongliang Ji Mengjun Yang Manman Xu Yunyan Zhou Wei Xie Zhuojuan Luo Chengqi Lin | 2019 | Journal of Molecular Cell Biology2019，11，9： | 3 |

| 11 | A single-cell transcriptome of mesenchymal stromal cells to fabricate bioactive hydroxyapatite materials for bone regeneration显示文摘The osteogenic microenvironment of bone-repairing materials plays a key role in accelerating bone regeneration but remains incompletely defined,which significantly limits the application of such bioactive materials.Here,the transcriptional landscapes of different osteogenic microenvironments,including three-dimensional(3D)hydroxyapatite(HA)scaffolds and osteogenic medium(OM),for mesenchymal stromal cells(MSCs)in vitro were mapped at single-cell resolution.Our findings suggested that an osteogenic process reminiscent of endochondral ossification occurred in HA scaffolds through sequential activation of osteogenic-related signaling pathways,along with inflammation and angiogenesis,but inhibition of adipogenesis and fibrosis.Moreover,we revealed the mechanism during OM-mediated osteogenesis involves the ZBTB16 and WNT signaling pathways.Heterogeneity of MSCs was also demonstrated.In vitro ossification of LRRC75A+MSCs was shown to have better utilization of WNT-related ossification process,and PCDH10+MSCs with superiority in hydroxyapatite-related osteogenic process.These findings provided further understanding of the cellular activity modulated by OM conditions and HA scaffolds,providing new insights for the improvement of osteogenic biomaterials.This atlas provides a blueprint for research on MSC heterogeneity and the osteogenic microenvironment of HA scaffolds and a database reference for the application of bioactive materials for bone regeneration. | Peng Guo Xizhe Liu Penghui Zhang Zhongyuan He Zhen Li Mauro Alini RGeoff Richards Sibylle Grad Martin J.Stoddart Guangqian Zhou Xuenong Zou Danny Chan Wei Tian Dafu Chen Manman Gao Zhiyu Zhou Shaoyu Liu | 2022 | Bioactive Materials2022，7，3： | 3 |
| 12 | The Effect of Unannounced Inspection on Prevention of Drug Fraud显示文摘Alarge number of incidents related to fake/inferior-quality drugs have occurred in China in recent years. In order to reduce drug crimes, the China Food and Drug Administration (CFDA) has exploited the new supervision approach, i.e., unannounced inspection (UI), since September 2014. However, the effectiveness of UI in driving drug producers to put more effort into meeting the requirements of Good Manufacturing Practice (GMP) is yet to be ascertained. In this paper we apply game theory to study the effects of UI on the prevention of drug fraud, drug producers’ profits, and social welfare under scenarios of complete and incomplete information. We show that UI is not always an effective way of supervision. Specifically, if the upper bound on the punishment is not very large, UI can drive the firmto make the largest self-supervision effort only when the firm’s technical level is high and the supervision cost is low. Otherwise, UI cannot drive the firm to make the largest self-supervision effort. Under incomplete information, firms with a high technical level would adopt more self-supervision and make more profit than those with a low technical level. Moreover, we design a new mechanism under incomplete information that can incentive drug producers to make greater self-supervision effort to meet the requirements of GMP under certain conditions. | Manman Zhang Juliang Zhang T.C.E.

| 13 | Analysis of the Winter Cloud-to-Ground Lightning Activity and Its Synoptic Background in China during 2010-20显示文摘Cloud-to-ground(CG)lightning data and the ECMWF ERA-Interim reanalysis dataset are analyzed to gain insight into the spatiotemporal distribution and synoptic background of winter-season CG flashes between December 2010 and February 2020 in China.We identify three Winter Lightning Frequent Areas(WLAs):the southwest side of the Yunnan-Guizhou Plateau(WLA1),the east side of the Yunnan-Guizhou Plateau(WLA2),and the Poyang Lake Plain(WLA3).The CG lightning flashes most frequently occur at local midnight and have a monthly peak in February.The CG lightning in WLA1 is mostly generated in non-frontal weather;however,the lightning in WLA2 and WLA3 mostly occurs in frontal systems.The frontal circulation situation is divided into four typical types:transversal trough after high pressure,low vortex,confrontational convergence,and asymptotic convergence.In all typical weather patterns,the lightning occurs downstream of a 500 hPa trough and is accompanied by a southwesterly low-level jet.The convective parameters of winter thunderstorms differ greatly from those of summer thunderstorms.The maximum convective available potential energy(MCAPE)and K-index(KI)are more useful metrics than convective available potential energy(CAPE)and Showalter index(SI)during winter.This study further deepens the understanding of the distribution characteristics of winter CG lightning in China,which motivates further research to improve the ability of winter thunderstorm prediction. | Manman MA Xiaogang HUANG Jianfang FEI Chi ZHANG Chao LI Xiaoping CHENG | 2022 | Advances in Atmospheric Sciences2022，39，6： | 2 |

| 17 | In situ fabrication of Na3V2(PO4)3 quantum dots in hard carbon nanosheets by using lignocelluloses for sodium ion batteries显示文摘The rational assembly of quantum dots on two-dimensional(2 D) carbonaceous materials is very promising to produce materials, but remains a challenge. Here, we develop an assembly strategy of growing Na3 V2(PO4)3 quantum dots with superlattice structure(NVP-QDs-SL) for obtaining precise control of the size, distribution and crystallinity. The multifunctional lignocelluloses(LCs) used as a hard carbon source induce heterogeneous nucleation and confined growth of NVP-QDs-SL, leading to the uniform distribution of NVP-QDs-SL in H/S-doped hard carbon ultra-thin nanosheets(HCS). Detailed electrochemical analysis results from sodium-ion batteries of NVP-QDs-SL show that NVP-QDs-SL could trap the electrons inside HCS, significantly enhancing Na ion storage and transfer kinetics. Compared to the common Na3 V2(PO4)3 nanoparticle cathode, the NVP-QDs-SL/HCS cathode exhibits a high reversible capacity of 149.2 m A h g^-1 at a 0.1 C rate, which is far beyond the theoretical capacity of Na3 V2(PO4)3(117.6 m A h g^-1).At the ultrahigh current rate of 100 C, this cathode still remains a high discharge capacity of 40 m A h g-1.Even after cycling at 20 C over 3000 cycles, an ultrahigh coulombic efficiency close to 100% is still obtained,highlighting its excellent long cycling life, remarkable rate performance and energy density. | Qihao Zhang Xudong Zhang Wen He Guogang Xu Manman Ren Jinhua Liu Xuena Yang Feng Wang | 2019 | Journal of Materials Science & Technology2019，35，10： | 1 |
| 18 | Development of a Widely Applicable and Simple Prognostic Score for Patients with Acute-on-chronic Liver Failure显示文摘Background and Aims:Acute-on-chronic liver failure(ACLF)tends to progress rapidly with high short-term mortality.We aimed to create a widely applicable,simple prognostic(WASP)score for ACLF patients.Methods:A retrospective cohort of ACLF cases recruited from three centers in China were divided into training and validation sets to develop the new score.A prospective longitudinal cohort was recruited for further validation.Results:A total of 541 cases were included in the training set,and seven independent ACLF prognostic factors were screened to construct a new quantitative WASP-ACLF table.In the validation set of 671 cases,WASP-ACLF showed better predictive ability for 28-day and 90-day mortality than the currently used prognostic scores at baseline,day 3,week 1,and week 2.The predictive efficacy and clinical validity of the model improved over time.Patients were assigned to low-,intermediate-,and high-risk groups by their WASP-ACLF scores.Compared with the other two groups,intermediate-risk patients had a more uncertain prognosis,with a 90-day mortality of 44.4–50.6%.Sequential assessments at weeks 1 and 2 found the 90-day mortality of intermediate-risk groups was<20%forpatients with a≥2 point decrease in WASP-ACLF and was up to 56%for patients with a≥2 points increase.Similar results were observed in prospective data.Conclusions:The new ACLF prognostic score was simple,widely applicable,and had good predictive efficacy.Continuous assessments and trend of change in WASP-ACLF need to be considered,especially for intermediate-risk patients. | Zhenjun Yu Yu Zhang Yuhan Li Feng Zhou Manman Xu Shaoli You Yu Chen Bing Zhu Ming Kong Fangjiao Song Shaojie Xin Zhongping Duan Tao Han China Network for Severe Liver Diseases | 2022 | Journal of Clinical and Translational Hepatology2022，10，5： | 1 |

| 20 | A 2D covalent organic framework with ultra-large interlayer distance as high-rate anode material for lithium-ion batteries显示文摘Covalent organic frameworks(COFs)have been broadly investigated for energy storage systems.However,many COF-based anode materials suffer from low utilization of redox-active sites and sluggish ions/electrons transport caused by their densely stacked layers.Thus,it is still a great challenge to obtain COF-based anode materials with fast ions/electrons transport and thus superior rate performance.Herein,a redox-active piperazine-terephthalaldehyde(PA-TA)COF with ultra-large interlayer distance is designed and synthesized for high-rate anode material,which contains piperazine units adopting a chair-shaped conformation with the nonplanar linkages of a tetrahedral configuration.This unique structure renders PA-TA COF an ultra-large interlayer distance of 6.2Å,and further enables it to achieve outstanding rate and cycling performance.With a high specific capacity of 543 mAh·g^(−1) even after 400 cycles at 1.0 A·g^(−1),it still could afford a specific capacity of 207 mAh·g^(−1) even at a high current density of 5.0 A·g^(−1).Our study indicates that expanding the interlayer distance of COFs by rational molecular design would be of great importance to develop high-rate electrode materials for lithium-ion batteries. | Manman Wu Yang Zhao Hongtao Zhang Jie Zhu Yanfeng Ma Chenxi Li Yamin Zhang Yongsheng Chen | 2022 | Nano Research2022，15，11： | 1 |
