1Chromosome-scale genome assembly provides insights into the evolution and flavor synthesis of passion fruit (Passiflora edulis Sims)显示文摘Passion fruit(Passiflora edulis Sims)is an economically valuable fruit that is cultivated in tropical and subtropical regions of the world.Here,we report an~1341.7Mb chromosome-scale genome assembly of passion fruit,with 98.91%(~1327.18Mb)of the assembly assigned to nine pseudochromosomes.The genome includes 23,171 protein-coding genes,and most of the assembled sequences are repetitive sequences,with long-terminal repeats(LTRs)being the most abundant.Phylogenetic analysis revealed that passion fruit diverged after Brassicaceae and before Euphorbiaceae.Ks analysis showed that two whole-genome duplication events occurred in passion fruit at 65 MYA and 12 MYA,which may have contributed to its large genome size.An integrated analysis of genomic,transcriptomic,and metabolomic data showed that‘alpha-linolenic acid metabolism’,‘metabolic pathways’,and‘secondary metabolic pathways’were the main pathways involved in the synthesis of important volatile organic compounds(VOCs)in passion fruit,and this analysis identified some candidate genes,including GDP-fucose Transporter 1-like,Tetratricopeptide repeat protein 33,protein NETWORKED 4B isoform X1,and Golgin Subfamily A member 6-like protein 22.In addition,we identified 13 important gene families in fatty acid pathways and eight important gene families in terpene pathways.Gene family analysis showed that the ACX,ADH,ALDH,and HPL gene families,especially ACX13/14/15/20,ADH13/26/33,ALDH1/4/21,and HPL4/6,were the key genes for ester synthesis,while the TPS gene family,especially PeTPS2/3/4/24,was the key gene family for terpene synthesis.This work provides insights into genome evolution and flavor trait biology and offers valuable resources for the improved cultivation of passion fruit.Zhiqiang Xia Dongmei Huang Shengkui Zhang Wenquan Wang Funing Ma Bin Wu Yi Xu Bingqiang Xu Di Chen Meiling Zou Huanyu Xu Xincheng Zhou Rulin Zhan Shun Song 2021Horticulture Research2021,8,1:15
2Immunomodulatory effect of human amniotic epithelial cells on restoration of ovarian function in mice with autoimmune ovarian disease显示文摘Autoimmune ovarian disease(AOD)is considered to be a major cause of premature ovarian failure(POF).The immunomodulatory properties of human amniotic epithelial cells(hAECs)have been studied in many disease models.We previously reported that hAECs restored ovarian function in chemotherapy-induced POF mice,but the immunomodulatory mechanism of hAECs is still unclear.To investigate the effect of hAECs on recipient mice,especially on regulatory Treg cells,hAECs and hAEC-conditioned medium(hAEC-CM)were intravenously injected into AOD mice immunized with zona pellucida protein 3 peptides(pZP3).Ovarian function was evaluated through estrous cycle,hormone secretion,follicle development,and cell apoptosis analysis.Immune cells including CD3,CD4,CD8 and Treg cells in the spleens were tested by flow cytometry.To elucidate the effect of hAEC-CM on macrophage function,inflammation model in vitrowas established in RAW264.7 cells induced by lipopolysaccharide(LPS).hAECs and hAEC-CM regulated estrous cycles,promoted follicle development,ameliorated cell apoptosis and fibrosis in ovaries of AOD mice.In addition,hAECs significantly reversed the decrease of pZP3-induced Treg cells in the spleens.In vitro,hAEC-CM significantly inhibited the inflammatory reaction induced by LPS in RAW264.7 cells via up-regulating the expression of M2 macrophage genes.Further study demonstrated that hAECsecreted transforming growth factor-beta and macrophage inhibitory factor played important roles in the macrophage polarization and migration under inflammatory stimulation.Taken together,hAECs restored ovarian function by up-regulating Treg cells in the spleens and reduced the inflammatory reaction via modulating the activated macrophage function in a paracrine manner in the ovaries of AOD mice.Qiuwan Zhang Yating Huang Junyan Sun Tingting Gu Xiaoyan Shao Dongmei Lai 2019Acta Biochimica et Biophysica Sinica2019,51,8:14
3MiRNA-429 suppresses the growth of gastric cancer cells in vitro显示文摘Micro-RNAs(miRNAs) have been found to be implicated in a very wide range of physiological processes.This study was aimed to investigate the regulation of miRNA-429(miR-429) in gastric cancer cells on cell proliferation and apoptosis.Quantitative PCR was employed to detect the expressions of miR-429 after eukaryotic expression plasmid of miR-429 and its inhibitor were transiently transfected into poorly differentiated human gastric can-cer cell line BGC823.The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT) reduction as-says were used to examine proliferation ability.Apoptosis was analyzed by flow cytometry after transfection.The results showed that 48 h after transfection,overexpression of miR-429 reached maximum efficiency.Compared with mock transfection,miR-429 inhibited tumor cell proliferation significantly(P < 0.05) at 48 h and 72 h.of Overexpression of miR-429 promoted tumor cell apoptosis when compared with mock transfected cells(P < 0.05).On the contrary,miR-429 inhibitor promoted tumor cell proliferation and inhibited apoptosis when compared with controls(P < 0.05).Our results suggested that miRNA-429 may serve as a tumor suppressor during tumorigenesis of gastric cancer and may be a potential gastric cancer therapeutic target.Di Liu Peng Xia Dongmei Diao Yao Cheng Hao Zhang Dawei Yuan Chen Huang Chengxue Dang 2012The Journal of Biomedical Research2012,26,5:12
4Comparative Transcriptome Analysis of Actinidia arguta Fruits Reveals the Involvement of Various Transcription Factors in Ripening显示文摘The fruit of Actinidia arguta is typically climacteric.During ripening,the fruits produce a large amount of ethylene.Although the molecular basis of climacteric fruit ripening has been extensively studied,some aspects such as its transcriptional regulation remain unclear.Here,we compared the transcriptomes of A.arguta fruits collected at commercial harvest(sample d0)and at 6 days after harvest(sample d6)using RNA-seq.A total of 3 659 differentially expressed genes(DEGs)between samples d0 and d6 were detected,of which 2 983 and 1 104 could be functionally annotated with Gene Ontology(GO)and Clusters of Orthologous Groups(COG)pathways.DEGs involved in ethylene biosynthesis and signal transduction were identified,including ACO(c79627),ERF061(c105131),and ERF6(c99193).Transcription factors such as ERF,b HLH,NAC,MADS,and MYB were also differentially expressed between samples d0 and d6.Selected DEGs were subjected to further analysis using quantitative reverse transcription-polymerase chain reaction(q RT-PCR),and the results coincided with those of RNA-seq.Our data revealed additional transcription factors that are involved in the regulation of fruit ripening.These results provide useful information for future research on the transcriptional regulation of fruit ripening.HUANG Guohui QU Yi LI Tong YUAN Hui WANG Aide TAN Dongmei 2018Horticultural Plant Journal2018,4,1:9
5Secreted Frizzled-Related Protein 5 (SFRP5) in Patients with Obstructive Sleep Apnea显示文摘Objective Obstructive sleep apnea (OSA) is closely related to obesity, insulin resistance and inflammation. Secreted frizzled-related protein 5 (SFRP5) is a recently discovered adipokine. It is involved in insulin resistance and inflammation in obesity. This study aimed at evaluating the association between SFRP5and sleeping characteristics as well as biochemical parameters of OSA patients.Methods This was a prospective case control study. Nondiabetic OSA patients and controls were consecutively recruited and divided into three groups: OSA group, apnea–hypopnea Index (AHI)≥5/h; healthy controls with normal body mass index (BMI); obese controls without OSA, and BMI > 24.0 kg/m2. All participants underwent polysomnography (PSG). Plasma SFRP5 was examined using enzyme-linked immunosorbent assay (ELISA). Blood biochemical examinations, including fasting blood glucose (FBG), lipid profile, hypersensitive Creactive protein (hsCRP), were performed early in the morning after PSG. Patients with severe OSA were treated with nasal continuous positive airway pressure (nCPAP), and plasma SFRP5 was repeatedly measured for comparison.Results Sixty-eight subjects were enrolled in the study, including 38 patients of OSA, whose medium AHI was 58.70 /h (36.63, 71.15), 20 obese controls, and 10 healthy controls. The plasma SFRP5 level of OSA patients was not significantly different from that of healthy controls or obese controls. In OSA patients, SFRP5 level correlated positively with triglyceride level (r=0.447, P=0.005) and negatively with LDL-cholesterol level and HDLcholesterol level (r=?0.472 and P=0.003; r=?0.478 and P=0.002; respectively). SFRP5 level was not found correlating with FBG, AHI, or any of nocturnal hypoxia parameters. After overnight nCPAP treatment, plasma SFRP5 levels of OSA patients did not change significantly (t=1.557, P = 0.148) compared to that of pretreatment.Conclusions In nondiabetic OSA patients, plasma SFRP5 is associated with the lipid profile. However,no correlation was observed between SFRP5 and FBG or sleep parameters. The SFRP5 level of OSA patients did not differ from that of non-OSA individuals in our study.Dongmei Zhang Rong Huang Yi Xiao Fengying Gong Xu Zhong Jinmei Luo 2017Chinese Medical Sciences Journal2017,32,4:7
6Response regimes of nonlinear energy harvesters with a resistorinductor resonant circuit by complexification-averaging method显示文摘In this paper, the steady-state response regimes of nonlinear energy harvesters with a resistor-inductor resonant circuit are theoretically investigated. The complexification averaging(CA) method is used to theoretically analyze the energy harvesting performance and reduce the motion equations into a set of first-order differential equations. The amplitudes and phases of both the response displacement and the output voltage are derived, and the corresponding stability conditions are determined. The response regimes are studied with the variation of nonlinear stiffness coefficients and coupling parameters, which are verified by the time domain analysis. The frequency island phenomenon is found and analyzed. Additionally, the backbone curve for deducing the extreme vibration frequency and amplitude is derived. Simultaneously, the analytical expressions of the switching points(critical amplitude and frequency) to identify the hardening and softening properties are established. Accordingly, a criterion is given to determine the occurrence of the jump phenomenon, and its effectiveness is verified. Overall, this paper presents an in-depth theoretical analysis of nonlinear energy harvesters with a resistor-inductor resonant circuit. It presents the theoretical framework and guidance for more extensive evaluations and understanding the theoretical analysis of nonlinear energy harvesters with external circuits.HUANG DongMei CHEN JiaYi ZHOU ShengXi FANG XueLai LI Wei 2021Science China(Technological Sciences)2021,64,6:6
7China Nutrition and Health Surveys(1982−2017)显示文摘The status of nutrition and health among residents is one of the important indicators reflecting the developing level in a country or a region.China’s government initiated the first China National Nutrition Survey in 1959.The Second National Nutrition Survey and the Third National Nutrition Survey were then conducted in 1982 and 1992,respectively(1-2).The China National Nutrition and Health Survey(2002)combined the nutrition and chronic diseases survey and became the fourth survey(3).Dongmei Yu Liyun Zhao Jian Zhang Zhenyu Yang Lichen Yang Jian Huang Hongyun Fang Qiya Guo Xiaoli Xu Lahong Ju Gangqiang Ding 2021China CDC weekly2021,3,9:6

9Oxidation of NO over cobalt oxide supported on mesoporous silica显示文摘Cobalt oxide catalysts supported on mesoporous silica(Co3O4 /MPS) were prepared,characterized and applied for catalytic oxidation of NO. Effects of catalyst supports,calcination temperatures,H2O and SO2 on NO conversion were investigated. The samples were also characterized by BET,XRD,FTIR and TG/DTG. The results suggested that Co3O4 /MPS catalyst calcined at 573 K had the smallest crystal particles and the best surface dispersion. This catalyst had the highest activity and yielded 82% NO conversion at 573 K,at a space velocity of 12000 h 1 . Although the conversion of NO decreased with the introduction of H2O,it could be restored completely after removing residual H2O from Co3O4 /MPS catalyst by heating at 573 K. In the presence of SO2,the oxidation activity decreased and CoSO 4 was detected on the catalyst. The NO conversion decreased to 30.2% in the presence of SO2 and H2O. It could not be restored completely after cutting off H2O and SO2 . The deactivation of the catalyst in the presence of SO2 and H2O was attributed to the formation of cobalt sulfate species.Yan Huang Dongmei Gao Zhiquan Tong Junfeng Zhang He Luo 2009Journal of Natural Gas Chemistry2009,18,4:5
10Comparative pharmacokinetics of tetramethylpyrazine phosphate in rat plasma and extracellular fluid of brain after intranasal,intragastric and intravenous administration显示文摘The purpose of this study was to compare the pharmacokinetic profiles of tetramethylpyrazine phosphate(TMPP)in plasma and extracellular fluid of the cerebral cortex of rats via three delivery routes:intranasal(i.n.),intragastric(i.g.)and intravenous(i.v.)administration.After i.n.,i.g.and i.v.administration of a single-dose at 10 mg/kg,cerebral cortex dialysates and plasma samples drawn from the carotid artery were collected at timed intervals.The concentration of TMPP in the samples was analyzed by HPLC.The area under the concentration-time curve(AUC)and the ratio of the AUCbrain to the AUCplasma(drug targeting efficiency,DTE)was calculated to evaluate the brain targeting efficiency of the drug via these different routes of administration.After i.n.administration,TMPP was rapidly absorbed to reach its peak plasma concentration within 5 min and showed a delayed uptake into cerebral cortex(t_(max)=15 min).The ratio of the AUCbrain dialysates value between i.n.route and i.v.injection was 0.68,which was greater than that obtained after i.g.administration(0.43).The systemic bioavailability obtained with i.n.administration was greater than that obtained by the i.g.route(86.33%vs.50.39%),whereas the DTE of the nasal route was 78.89%,close to that of oral administration(85.69%).These results indicate that TMPP is rapidly absorbed from the nasal mucosa into the systemic circulation,and then crosses the blood-brain barrier(BBB)to reach the cerebral cortex.Intranasal administration of TMPP could be a promising alternative to intravenous and oral approaches.Dongmei Meng Haoyang Lu Shanshan Huang Minyan Wei Pingtian Ding Xianglin Xiao Yuehong Xu Chuanbin Wu 2014Acta Pharmaceutica Sinica B2014,4,1:5
11The correlation and overlaps between PD-L1 expression and classical genomic aberrations in Chinese lung adenocarcinoma patients: a single center case series显示文摘Objective:To investigate the correlation and overlaps between PD-L1 expression and classical genomic aberrations in Chinese lung adenocarcinoma(LADC)patients.Methods:We reviewed 428 consecutive,surgically resected cases of LADC from October 2015 to December 2016 from our center.PD-L1 expression was evaluated based on tumor proportion score(TPS).Correlation and co-occurrence of PD-L1 expression level with those of classical driver genes,such as EGFR,ALK,ROS-1,and KRAS and with clinical variables and disease-free survival(DFS)were analyzed.Results:Seventy of the 428 cases(16.4%)showed TPS≥1%,and 21 cases(4.9%)showed TPS≥50%.PD-L1 positive expression was significantly associated with male gender,smoking,advanced TNM stage,and solid histologic subtype.Both TPS≥1% and ≥50%were correlated with the absence of an EGFR mutation(P<0.001)and the presence of ALK rearrangement(P=0.024).KRAS mutation was associated with TPS≥50%(P=0.035).PD-L1 positivity commonly overlapped with the alterations of classical driver oncogenes(58.5%with TPS≥1% and 42.9% with TPS≥50%).Approximately three-quarters of PD-L1 positive cases co-occurred with classical therapeutic-gene aberrations in cases with stage III/IV cancer or cancer progression.LADC could be divided into four subgroups based on the expression profile of current routine biomarkers for potential therapeutic strategies.Conclusions:PD-L1 expression is not only closely correlated with classic gene alterations but also commonly overlaps with the aberrations of classical driver oncogenes in Chinese LADC patients.These findings provide a useful overview of clinical strategies that rely on the profile of routinely used molecular biomarkers.Jianghua Wu Wei Sun Haiyue Wang Xiaozheng Huang Xinyu Wang Weiyang Jiang Ling Jia Ping Wang Qin Feng Dongmei Lin 2019Cancer Biology & Medicine2019,16,4:5
12Fragility assessment of tunnels in soft soils using artificial neural networks显示文摘Recent earthquakes have shown that tunnels are prone to damage,posing a major threat to safety and having major cascading and socioeconomic impacts.Therefore,reliable models are needed for the seismic fragility assessment of underground structures and the quantitative evaluation of expected losses.Based on previous researches,this paper presented a probabilistic framework based on an artificial neural network(ANN),aiming at the development of fragility curves for circular tunnels in soft soils.Initially,a two-dimensional incremental dynamic analysis of the nonlinear soil-tunnel system was performed to estimate the response of the tunnel under ground shaking.The effects of soil-structure-interaction and the ground motion characteristics on the seismic response and the fragility of tunnels were adequately considered within the proposed framework.An ANN was employed to develop a probabilistic seismic demand model,and its results were compared with the traditional linear regression models.Fragility curves were generated for various damage states,accounting for the associated uncertainties.The results indicate that the proposed ANN-based probabilistic framework can results in reliable fragility models,having similar capabilities as the traditional approaches,and a lower computational cost is required.The proposed fragility models can be adopted for the risk analysis of typical circular tunnel in soft soils subjected to seismic loading,and they are expected to facilitate decision-making and risk management toward more resilient transport infrastructure.Zhongkai Huang Sotirios A.Argyroudis Kyriazis Pitilakis Dongmei Zhang Grigorios Tsinidis 2022Underground Space2022,7,2:4

14Influence of Cr^(3+) concentration on the electrochemical behavior of the anolyte for vanadium redox flow batteries显示文摘The composition of electrolyte affects to a great extent the electrochemical performance of vanadium redox flow batteries(VRB).The effects of Cr3+ concentration in the anolyte on the electrode process of V(V)/V(IV) couple have been investigated by cyclic voltammetry(CV) and electrochemical impedance spectroscopy(EIS).It was found that Cr3+ causes no side reactions,but affects the electrochemical performance of V(V)/V(IV) redox reaction,including the reaction activity,the reversibility of electrode reaction,the diffusivity of vanadium ions,the interface film impedance,and the electrode reaction impedance.The experimental results show that Cr3+ within a certain concentration range can improve the reversibility of electrode reaction and the diffusion of vanadium ions.With the Cr3+ concentration increasing from 0 to 0.30 g L-1,the reversibility of V(V)/V(IV) reaction increases,while the diffusion resistance decreases.Correspondingly,the diffusion coefficient of vanadium ions increases from(5.48-6.77) × 10-7 to(6.82-8.44) × 10-7 cm2 s-1,an increase of ~24%.However,the diffusion resistance increases and the diffusion coefficient decreases when Cr3+ concentration is over 0.30 g L-1,while the impedances of the interface,the film as well as the charge transfer increase continuously.As a result,Cr3+ with a certain concentration improves the diffusion and mass transfer process,but the resistances of the film,the interface,and the charge transfer rise.Furthermore,Cr3+ concentration of no more than 0.10 g L-1 has few effect on the electrode reaction process,and that of no more than 0.30 g L-1 is favorable to the diffusion of vanadium ions.HUANG Fei ZHAO Qiang LUO ChunHui WANG GuiXin YAN KangPing LUO DongMei 2012Chinese Science Bulletin2012,57,32:4

16Glycine functionalized activated carbon derived from navel orange peel for enhancement recovery of Gd(Ⅲ)显示文摘Glycine functionalized activated carbon adsorption material(NOPAC-GLY-X)was successfully prepared by one-step thermal decomposition using agricultural waste navel orange peel as a precursor.Through batch adsorption experiments,it is found that the adsorption performance of Gd(Ⅲ)on activated carbon can be significantly enhanced by glycine modification.The adsorption isotherms of the NOPACs conform to the Langmuir isotherm model,and the maximum adsorption capacity of the activated carbon sample NOPAC-Gly-60 is approximately 48.5 mg/g.The Gd(Ⅲ)adsorption capacity of navel orange peel activated carbon can be doubled after glycine modification,and the adsorption efficiency of gadolinium can reach99%at pH=7.The physicochemical properties of the prepared adsorbents were characterized by Brunauer-Emmett-Teller(BET),Fourier transform infrared spectroscopy(FTIR),elemental analysis(EA),and X-ray photoelectron spectroscopy(XPS).The characterization test shows that the specific surface area of the sample increases from 1121 to 1523 m^(2)/g,and the ratio of(N+O)/C increases from 10.8%to 30.0%by the glycine modification.After five cycles of adsorption-desorption,the adsorption capacity can still be maintained at 88%of the initial capacity.NOPAC-GLY-60 has excellent adsorption selectivity for Gd(Ⅲ).With the obvious advantages of simple synthesis steps and low cost,the activated carbon modification method adopted in this study has great application value in the field of rare earth adsorption and recovery.Bin Xiao Lijinhong Huang Wanfu Huang Dongmei Zhang Xiangrong Zeng Xiaohui Yao 2022Journal of Rare Earths2022,40,11:3
17Study of tide prediction method influenced by nonperiodic factors based on support vector machines显示文摘Harmonic analysis, the traditional tidal forecasting method, cannot take into account the impact of noncyclical factors, and is also based on the BP neural network tidal prediction model which is easily limited by the amount of data. According to the movement of celestial bodies, and considering the insufficient tidal characteristics of historical data which are impacted by the nonperiodic weather, a tidal prediction method is designed based on support vector machine (SVM) to carry out the simulation experiment by using tidal data from Xiamen Tide Gauge, Luchaogang Tide Gauge and Weifang Tide Gauge individually. And the results show that the model satisfactorily carries out the tide prediction which is influenced by noncyclical factors. At the same time, it also proves that the proposed prediction method, which when compared with harmonic analysis method and the BP neural network method, has faster modeling speed, higher prediction precision and stronger generalization ability.HE Shi-jun ZHOU Wenjun ZHOU Ruyan HUANG Dongmei 2012Acta Oceanologica Sinica2012,31,5:3
18Unified modeling of the monotonic and cyclic behaviors of sand and clay显示文摘In this study, we aim to investigate a unified modeling method for the monotonic and cyclic behaviors of sand and clay. A simple double-yield-surface model, with plastic hardening modulus and dilatancy relation being dependent on density state unlike in existing approaches,is developed by considering the location of the critical state line. The model is used to simulate the drained and undrained tests of various sands and clays under monotonic and cyclic loadings.Prediction results are compared with experimental results, which show that the proposed approach is capable of modeling the monotonic and cyclic behaviors of sand and clay.Yinfu Jin Zhenyu Yin Dongmei Zhang Hongwei Huang 2015Acta Mechanica Solida Sinica2015,28,2:3
19Densification and anticorrosion performances of vacuum evaporated aluminium coatings on NdFeB magnets显示文摘Al coated NdFeB magnets obtained by vacuum evaporation technique were densified by high energy ball milling method.The surface morphology,metal composition and micro structure of the coatings were characterized by scanning electron microscopy,X-ray diffraction and X-ray photoelectron spectroscopy,respectively.The anticorrosive properties were investigated by potentiodynamic polarization curves and neutral salt spray test.The pores in the Al coatings of columnar crystals(Al) induced by the evaporation technique,were apparently filled in the following ball milling process,leading to the densification of Al coatings and the evident improvement of the anticorrosive performances.When treated with ball milling for 30 min,the sample achieves the best anticorrosive performances with the self-corrosion potential of-0.87 V,self-corrosion current density of 1.65 μA/cm^(2) and the neutral salt spray(NSS) time of 144 h(red rust).The improvement of the anticorro sive performances of vacuum evaporated Al coating mainly lies in the densification effect of the coating,which depends on different loading conditions of ball milling process.Jun Huang Qing Liu Zhenyu Yang Guangqing Xu Pengjie Zhang Jun Lv Wei Sun Bingshan Li Dongmei Wang Yucheng Wu 2021Journal of Rare Earths2021,39,10:3
20Roles of State Strategy of Adaptation to Climate Change in China显示文摘For the adverse impacts of climate change, China gov- ernment should place the problem of adaptation to climate change on the agenda. It is time to institute and implement a state adap- tive strategy to reduce the adverse impacts on economy, commu- nity and people's health and life by international cooperation and our own endeavor. A state strategy of adaptation to climate change should be closely linked with other current interrelated national strategies, and they should be supplemented and improved by each other. This paper discusses the roles of the state strategy of adaptation to climate change in the state climate change integra- tive strategy, the environmental protection strategy, and the sus- tainable development strategy in China. Furthermore, it proposes the main aims of the state adaptive strategy of China.Jiang Dongmei Wang Can Huang Shanfeng Zhang Mengheng 2007Chinese Journal of Population,Resources and Environment2007,5,4:3
