| 1 | Chromosome-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 | 2021 | Horticulture Research2021，8，1： | 15 |
| 2 | Long Distance Transmission of SARS-CoV-2 from Contaminated Cold Chain Products to Humans——Qingdao City,Shandong Province,China,September 2020显示文摘Summary What is already known about this topic?Though coronavirus disease 2019(COVID-19)has largely been controlled in China,several outbreaks of COVID-19 have occurred from importation of cases or of suspected virus-contaminated products.Though several outbreaks have been traced to severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)isolated on the outer packaging of cold chain products,live virus has not been obtained. | Huilai Ma Zhaoguo Wang Xiang Zhao Jun Han Yong Zhang Hong Wang Cao Chen Ji Wang Fachun Jiang Jie Lei Jingdong Song Shaofeng Jiang Shuangli Zhu Huihui Liu Dongyan Wang Yao Meng Naiying Mao Yanhai Wang Zhen Zhu Zhixiao Chen Bingling Wang Qinqin Song Haijun Du Qun Yuan Dong Xia Zhiqiang Xia Peipei Liu Yuchao Wu Zijian Feng Ruqin Gao George F.Gao Wenbo Xu | 2021 | China CDC weekly2021，3，30： | 13 |
| 3 | Clinical significance of stanniocalcin expression in tissue and serum of gastric cancer patients显示文摘Purpose: Stanniocalcin(STC) has been recognized as a potential biomarker in a variety of cancers. The aim of this study was to examine STC1 and STC2 expression in tumor and serum samples from gastric cancer(GC) patients.Methods: A total of 83 GC patients treated with radical resection were enrolled in this study. Immunohistochemistry was used to detect STC protein expression in paired tumor and adjacent normal tissues. Serum STC levels were determined by enzyme-linked immunosorbent assay(ELISA). The receiver operating characteristics(ROC) curve was constructed to describe diagnostic specificity and sensitivity. Results: Both of STC1 and STC2 protein expression were upregulated in GC tissues compared with that in normal ones. Moreover, the high/moderate of STC1 protein was significantly associated with lymph metastasis, clinical stage and adverse 3-year progression-free survival(PFS). In addition, serum STC1 and STC2 expression in GC patients were much higher than that in patients with benign gastric disease, which decreased at postoperative 7-10 days. The sensitivity of serum STC protein also showed superiority over CEA and CA19-9. Conclusions: STC upregulation plays an important role in GC development, and serum STC1 and STC2 might function as promising tumor markers for GC diagnosis and prognosis. | Zheng Fang Zhiqiang Tian Kunlun Luo Haizhu Song Jun Yi | 2014 | Chinese Journal of Cancer Research2014，26，5： | 12 |
| 4 | Towards reliable Arctic sea ice prediction using multivariate data assimilation显示文摘Rapid declines in Arctic sea ice have captured attention and pose significant challenges to a variety of stakeholders. There is a rising demand for Arctic sea ice prediction at daily to seasonal time scales, which is partly a sea ice initial condition problem. Thus, a multivariate data assimilation that integrates sea ice observations to generate realistic and skillful model initialization is needed to improve predictive skill of Arctic sea ice. Sea ice data assimilation is a relatively new research area. In this review paper, we focus on two challenges for implementing multivariate data assimilation systems for sea ice forecast. First, to address the challenge of limited spatiotemporal coverage and large uncertainties of observations, we discuss sea ice parameters derived from satellite remote sensing that(1) have been utilized for improved model initialization, including concentration, thickness and drift, and(2) are currently under development with the potential for enhancing the predictability of Arctic sea ice, including melt ponds and sea ice leads. Second, to strive to generate the ‘‘best' estimate of sea ice initial conditions by combining model simulations/forecasts and observations, we review capabilities and limitations of different data assimilation techniques that have been developed and used to assimilate observed sea ice parameters in dynamical models. | Jiping Liu Zhiqiang Chen Yongyun Hu Yuanyuan Zhang Yifan Ding Xiao Cheng Qinghua Yang Lars Nerger Gunnar Spreen Radley Horton Jun Inoue Chaoyuan Yang Ming Li Mirong Song | 2019 | Science Bulletin2019，64，1： | 10 |

| 10 | The RppC-AvrRppC NLR-effector interaction mediates the resistance to southern corn rust in maize显示文摘Southern corn rust(SCR),caused by the fungal pathogen Puccinia polysora,is a major threat to maize pro-duction worldwide.Efficient breeding and deployment of resistant hybrids are key to achieving durable control of SCR.Here,we report the molecular cloning and characterization of RppC,which encodes an NLR-type immune receptor and is responsible for a major SCR resistance quantitative trait locus.Further-more,we identified the corresponding avirulence effector,AvrRppC,which is secreted by P.polysora and triggers RppC-mediated resistance.Allelic variation of AvrRppC directly determines the effectiveness of RppC-mediated resistance,indicating that monitoring of AvrRppC variants in the field can guide the rational deployment of RppC-containing hybrids in maize production.Currently,RppC is the most frequently deployed SCR resistance gene in China,and a better understanding of its mode of action is crit-ical for extending its durability. | Ce Deng April Leonard James Cahill Meng Lv Yurong Li Shawn Thatcher Xueying Li Xiaodi Zhao Wenjie Du Zheng Li Huimin Li Victor Llaca Kevin Fengler Lisa Marshall Charlotte Harris Girma Tabor Zhimin Li Zhiqiang Tian Qinghua Yang Yanhui Chen Jihua Tang Xintao Wang Junjie Hao Jianbing Yan Zhibing Lai Xiaohong Fei Weibin Song Jinsheng Lai Xuecai Zhang Guoping Shu Yibo Wang Yuxiao Chang Weiling Zhu Wei Xiong Juan Sun Bailin Li Junqiang Ding | 2022 | Molecular Plant2022，15，5： | 6 |

| 12 | Extracorporeal membrane oxygenation combined with continuous renal replacement therapy for the treatment of severe burns:current status and challenges显示文摘Severe burns often cause various systemic complications and multiple organ dysfunction syndrome,which is the main cause of death.The lungs and kidneys are vulnerable organs in patients with multiple organ dysfunction syndrome after burns.Extracorporeal membrane oxygenation(ECMO)and continuous renal replacement therapy(CRRT)have been gradually applied in clinical practice and are beneficial for severe burn patients with refractory respiratory failure or renal dysfunction.However,the literature on ECMO combined with CRRT for the treatment of severe burns is limited.Here,we focus on the current status of ECMO combined with CRRT for the treatment of severe burns and the associated challenges,including the timing of treatment,nutrition support,heparinization and wound management,catheter-related infection and drug dosing in CRRT.With the advancement of medical technology,ECMO combined with CRRT will be further optimized to improve the outcomes of patients with severe burns. | Huapei Song Zhiqiang Yuan Yizhi Peng Gaoxing Luo | 2021 | Burns & Trauma2021，9，1： | 5 |
| 13 | 2022 Chinese national clinical practice guideline on Helicobacter pylori eradication treatment显示文摘Background:Helicobacter pylori(H.pylori)infection is an infectious disease with a prevalence rate of up to 50%worldwide.It can cause indigestion,gastritis,peptic ulcer,and gastric cancer.H.pylori eradication treatment can effectively control disease progression and reduce the risk of the above conditions.However,the escalating trend of antibiotic resistance presents a global challenge for H.pylori eradication.We aim to provide guidance on pharmacological treatment of H.pylori infection.Methods:This clinical practice guideline is developed following the World Health Organization’s recommended process,adopting Grading of Recommendations Assessment,Development and Evaluation in assessing evidence quality,and utilizing Evidence to Decision framework to formulate clinical recommendations,minimizing bias and increasing transparency of the clinical practice guideline development process.We used the Reporting Items for practice Guidelines in HealThcare(RIGHT)statement and The Appraisal of Guidelines for Research and Evaluation Ⅱ(AGREE Ⅱ)as reporting and conduct guides to ensure the guideline’s completeness and transparency.Results:Though decreasing in developed countries,the prevalence of H.pylori remains high in developing countries,causing a major public health burden.This clinical practice guideline contains 12 recommendations concerning pharmacological treatment for H.pylori eradication.Among them,it is worth highlighting that bismuth preparations are inexpensive,safe,and effective,consequently making bismuth quadruple therapy a preferred choice for initial and rescue treatment.In empirical treatment,high-dose dual therapy is equally effective compared with bismuth quadruple therapy.Conclusions:The 12 recommendations in this clinical practice guideline are formed with consideration for stakeholders’values and preferences,resource use,feasibility,and acceptability.Recommendations are generalizable to resource limited settings with similar antibiotic resistance pattern as China,and lower middle-income countries facing comparable sociological and technical challenges.Registration:Guidelines International Network(GIN)website,http://gffzz8d0dcdd112684267sxwvcvq6oncv56x0o.ffgz.tsg.suse.edu.cn/node/69996. | Liya Zhou Hong Lu Zhiqiang Song Bin Lyu Ye Chen Jiyao Wang Jun Xia Zhan Zhao on behalf of Helicobacter Pylori Study Group of Chinese Society of Gastroenterology | 2022 | Chinese Medical Journal2022，135，24： | 5 |
| 14 | Experimental and Numerical Studies of Vitiated Air Effects on Hydrogen-fueled Supersonic Combustor Performance显示文摘This paper deals with the vitiation effects of test air on the scramjet performance in the ground combustion heated facilities. The primary goal is to evaluate the effects of H2O and CO2, the two major vitiated species generated by combustion heater, on hydrogen-fueled supersonic combustor performance with experimental and numerical approaches. The comparative experiments in the clean air and vitiated air are conducted by using the resistance heated direct-connected facility, with the typical Mach 4 flight conditions simulated. The H2O and CO2 species with accurately controlled contents are added to the high enthalpy clean air from resistance heater, to synthesize the vitiated air of a combustion-type heater. Typically, the contents of H2O species can be varied within the range of 3.5%-30% by mole, and 3.0%-10% for CO2 species. The total temperature, total pressure, Mach number and O2 mole fraction at the combustor entrance are well-matched between the clean air and vitiated air. The combustion experiments are completed at the fuel equivalence ratios of 0.53 and 0.42 respectively. Furthermore, three-dimensional (3D) reacting flow simulations of combustor flowpath are performed to provide insight into flow field structures and combustion chemistry details that cannot resolved by experimental instruments available. Finally, the experimental data, combined with computational results, are employed to analyze the effects of H2O and CO2 vitiated air on supersonic combustion characteristics and performance. It is concluded that H2O and CO2 contaminants can significantly inhibit the combustion induced pressure rise measured from combustor wall, and the pressure profile decreases with the increasing H2O and CO2 contents in nonlinear trend; simulation results agree well with experimental data and the overall vitiation effects are captured; direct extrapolation of the results from vitiated air to predict the performance of actual flight conditions could result in over-fueling the combustor, possible inlet un-start and inappropriate combustion mode transition. The detailed analysis and discussion are presented and the research conclusions are summarized. | LUO Feiteng SONG Wenyan ZHANG Zhiqiang LI Weiqiang LI Jianping | 2012 | Chinese Journal of Aeronautics2012，25，2： | 5 |

| 18 | Extractive Desulfurization from Simulated Sulfur-Rich Naphtha显示文摘Upon extractive desulfurization of sulfur-rich oil obtained after recycling raffinate,the effects of single and compound extractants,temperature,and extractant/oil ratio on desulfurization rate,oil loss rate,extractant loss rate,and selectivity coefficient were investigated.The results showed that the thiophene existing in the simulated sulfur-rich oil could be further removed by extraction.The single-stage desulfurization rates achieved by dimethyl sulfoxide(DMSO)and sulfolane(SF)were 53.51%and 47.36%,respectively,while the selectivity coefficient of SF was 1.13,which was higher than that of DMSO(with a selectivity coefficient of 1.04).For the compound extractant,a single-stage desulfurization rate of 49.59%and a selectivity coefficient of 1.40 were obtained by using DMSO+10%MEA as the extractant,which was higher than that of SF.Upon using 50%SF+50%DMSO as the extractant,the single-stage desulfurization rate reached 50.92%with a selectivity coefficient of 1.32.Based on the comprehensive consideration,the DMSO+10%MEA extractant was selected as the best extractant for treating the sulfur-rich oil. | Shen Xizhou Li Zhiqiang Fang Liuya Song Hao Gan Feng Shen Zhi | 2019 | China Petroleum Processing & Petrochemical Technology2019，21，3： | 4 |
| 19 | Effect of electrode Pt-loading and cathode flow-field plate type on the degradation of PEMFC显示文摘The electrode Pt-loading has an effect on the number of active sites and the thickness of catalyst layer,which has huge influence on the mass transfer and water management during dynamic process in PEMFCs. In this study, membrane electrode assemblies with different Pt-loadings were prepared, and PEMFCs were assembled using those membrane electrode assemblies with traditional solid plate and water transport plate as cathode flow-field plates, respectively. The performance and electrochemical surface area of cells were characterized to evaluate the membrane electrode assemblies degradation after rapid currentvariation cycles. Scanning electron microscope and transmission electron microscope were used to investigate the decay of catalyst layers and Pt/C catalyst. With the increase of Pt-loading, the performance degradation of membrane electrode assemblies will be mitigated. But higher Pt-loading means thicker catalyst layer, which leads to a longer pathway of mass transfer, and it may result in carbon material corrosion in membrane electrode assemblies. The decay of Pt/C catalyst in cathode is mainly caused by the corrosion of carbon support, and the degradation of anode Pt/C catalyst is a consequence of migration and aggregation of Pt particles. And using water transport plate is beneficial to alleviating the age of cathode Pt/C catalyst. | Lijuan Qu Zhiqiang Wang Xiaoqian Guo Wei Song Feng Xie Liang He Zhigang Shao Baolian Yi | 2019 | Journal of Energy Chemistry2019，28，8： | 4 |
| 20 | A Novel Model of Predicting Archie's Cementation Factor from Nuclear Magnetic Resonance(NMR) Logs in Low Permeability Reservoirs显示文摘The resistivity experimental measurements of core samples drilled from low permeability reservoirs of Ordos Basin,Northwest China,illustrate that the cementation factors are not agminate,but vary from 1.335 to 1.749.This leads to a challenge for the estimation of water and hydrocarbon saturation.Based on the analysis of Purcell equation and assumption that rock resistivity is determined by the parallel connection of numerous capillary resistances,a theoretical expression of cementation factor in terms of porosity and permeability is established.Then,cementation factor can be calculated if the parameters of porosity and permeability are determined.In the field application,porosity can be easily obtained by conventional logs.However,it is a tough challenge to estimate permeability due to the strong heterogeneity of low permeability reservoirs.Thus,the Schlumberger Doll Research(SDR)model derived from NMR logs has been proposed to estimate permeability.Based on the analysis of the theoretical expressions of cementation factor and SDR model,a novel cementation factor prediction model,which is relevant to porosity and logarithmic mean of NMR T2spectrum(T2lm),is derived.The advantage of this model is that all the input information can be acquired from NMR logs accurately.In order to confirm the credibility of the novel model,the resistivity and corresponding laboratory NMR measurements of 27 core samples are conducted.The credibility of the model is confirmed by comparing the predicted cementation factors with the core analyzed results.The absolute errors for all core samples are lower than 0.071.Once this model is extended to field application,the accuracy of water and hydrocarbon saturation estimation will be significantly improved. | Liang Wang Zhiqiang Mao Yujiang Shi Qin'e Tao Yumei Cheng Yong Song | 2014 | Journal of Earth Science2014，25，1： | 4 |
