| 3 | Id2 regulates the proliferation of squamous cell carcinoma in vitro via the NF-κB/Cyclin D1 pathway显示文摘Squamous cell carcinoma (SCC) is a significant cause of cancer morbidity and mortality worldwide, with an incidence of up to 166 cases per 100 000 population. It arises in the skin, upper aerodigestive tract, lung, and cervix and affects more than 200 000 Americans each year. We report here that a microarray experiment comparing 41 SCC and 13 normal tissue specimens showed that Id2, a gene that controls the cell cycle, was significantly up-regulated in SCC. Enforced expression of Id2 in vitro stimulated the proliferation of SCC cells and up-regulated the transcription of nuclear factor kappa B (NF-κB) and cyclin D1. Enhancement of the NF-κB activity with p65 significantly increased the cell proliferation and the transcription of cyclin D1, whereas inhibition of the NF-κB activity with I kappa B alpha mutant (IκBα M) and pyrroline dithiocarbamate (PDTC) abrogated cell proliferation and transcription of cyclin D1. Furthermore, a mutated NF-κB binding site in the cyclin D1 promoter fully abrogated the Id2-induced transcription of cyclin D1. Taken together, these data indicate that Id2 induces SCC tumor growth and proliferation through the NF-κB/cyclin D1 pathway. | Chuan Wang Qiang Chen Yuki Hamajima Wei Sun Yi-Qing Zheng Xiao-Hua Hu Frank G.

| 5 | Sequencing a Juglans regia×J.microcarpa hybrid yields high-quality genome assemblies of parental species显示文摘Members of the genus Juglans are monecious wind-pollinated trees in the family Juglandaceae with highly heterozygous genomes,which greatly complicates genome sequence assembly.The genomes of interspecific hybrids are usually comprised of haploid genomes of parental species.We exploited this attribute of interspecific hybrids to avoid heterozygosity and sequenced an interspecific hybrid Juglans microcarpa×J.regia using a novel combination of single-molecule sequencing and optical genome mapping technologies.The resulting assemblies of both genomes were remarkably complete including chromosome termini and centromere regions.Chromosome termini consisted of arrays of telomeric repeats about 8 kb long and heterochromatic subtelomeric regions about 10 kb long.The centromeres consisted of arrays of a centromere-specific Gypsy retrotransposon and most contained genes,many of them transcribed.Juglans genomes evolved by a whole-genome-duplication dating back to the Cretaceous-Paleogene boundary and consist of two subgenomes,which were fractionated by numerous short gene deletions evenly distributed along the length of the chromosomes.Fractionation was shown to be asymmetric with one subgenome exhibiting greater gene loss than the other.The asymmetry of the process is ongoing and mirrors an asymmetry in gene expression between the subgenomes.Given the importance of J.microcarpa×J.regia hybrids as potential walnut rootstocks,we catalogued disease resistance genes in the parental genomes and studied their chromosomal distribution.We also estimated the molecular clock rates for woody perennials and deployed them in estimating divergence times of Juglans genomes and those of other woody perennials. | Tingting Zhu Le Wang Frank M.You Juan C.Rodriguez Karin R.Deal Limin Chen Jie Li Sandeep Chakraborty Bipin Balan Cai-Zhong Jiang Patrick J.Brown Charles ALeslie Mallikarjuna KAradhya Abhaya M.Dandekar Patrick E.McGuire Daniel Kluepfel Jan Dvorak Ming-Cheng Luo | 2019 | Horticulture Research2019，6，1： | 7 |
| 6 | Impact of an innovative financing and payment model on tuberculosis patients'financial burden:is tuberculosis care more affordable for the poor?显示文摘Background:In response to the high financial burden of health services facing tuberculosis(TB)patients in China,the China-Gates TB project,PhaseⅡ,has implemented a new financing and payment model as an important component of the overall project in three cities in eastern,central and western China.The model focuses on increasing the reimbursement rate for TB patients and reforming provider payment methods by replacing fee-for-service with a case-based payment approach.This study investigated changes in out-of-pocket(OOP)health expenditure and the financial burden on TB patients before and after the interventions,with a focus on potential differential impacts on patients from different income groups.Methods:Three sample counties in each of the three prefectures:Zhenjiang,Yichang and Hanzhong were chosen as study sites.TB patients who started and completed treatment before,and during the intervention period,were randomly sampled and surveyed at the baseline in 2013 and final evaluation in 2015 respectively.OOP health expenditure and percentage of patients incurring catastrophic health expenditure(CHE)were calculated for different income groups.OLS regression and Iogit regression were conducted to explore the intervention's impacts on patient OOP health expenditure and financial burden after adjusting for other covariates.Key-informant interviews and focus group discussions were conducted to understand the reasons for any observed changes.Results:Data from 738(baseline)and 735(evaluation)patients were available for analysis.Patient mean OOP health expenditure increased from RMB 3576 to RMB 5791,and the percentage of patients incurring CHE also increased after intervention.The percentage increase in OOP health expenditure and the likelihood of incurring CHE were significantly lower for patients from the highest income group as compared to the lowest.Qualitative findings indicated that increased use of health services not covered by the standard package of the model was likely to have caused the increase in financial burden.Conclusions:The implementation of the new financing and payment model did not protect patients,especially those from the lowest income group,from financial difficulty,due partly to their increased use of health service.More financial resources should be mobilized to increase financial protection,particularly for poor patients,while cost containment strategies need to be developed and effectively implemented to improve the effective coverage of essential healthcare in China. | Wei-Xi Jiang Qian Long Henry Lucas Di Dong Jia-Ying Chen Li Xiang Qiang Li Fei Huang Hong Wang Chris Elbers Frank Cobelens Sheng-Lan Tang | 2019 | Infectious Diseases of Poverty2019，8，2： | 4 |
| 7 | Phylogenetic Analyses Reveal a Unique Species of Elaphe(Serpentes,Colubridae)New to Science显示文摘The snakes comprising the monophyletic group referred to as ratsnakes are found throughout Asia,Europe and the New World.Recently,three snake samples likely belonging to the ratsnakes were collected in Zoige County,Sichuan Province,China.Species identity was difficult to delimit morphologically because the specimens were juveniles and partially damaged.Subsequently,a molecular phylogenetic approach was used.Portions of three mitochondrial genes(cyt b,ND4 and 12S rRNA) were sequenced and analyzed.The results showed that they were sister to the genus Elaphe.Very little genetic variation was found among the three samples.The minimum genetic distances between these samples and those within Elaphe were greater than any currently recognized species within the genus.We conclude that this likely represents a new species within the genus Elaphe.Adult specimens and a morphologic description are needed for further study. | LING Chen LIU Shaoying HUANG Song Frank T.Burbrink GUO Peng SUN Zhiyu ZHAO Jie | 2010 | Asian Herpetological Research2010，1，2： | 4 |

| 9 | OPTIMAL POLICY WITH A TOTAL ORDER QUANTITY COMMITMENT CONTRACT IN THE PRESENCE OF A SPOT MARKET显示文摘In this paper,the optimal policy is considered when the buyer faces two supply sources:one is the contract supplier from which the buyer orders over a specific contract period(say,a year) at a pre-agreed price,and the other is the spot market.However,when ordering from the contract supplier,the buyer must fulfill a pre-determined total order quantity,or the so-called definite total order quantity commitment,over the whole contract period.In other words,the commitment secures the buyer a fixed price but obliges him/her a total order quantity over the contract period.Although the spot market gives the buyer more flexibility in terms of order quantities,its prices are volatile.Such a combination of contract and spot procurements is often observed in practice.Within the contract period,there are multiple sub-periods,during each of which the buyer reviews the inventory,issues an individual order,and uses the on-hand inventory to meet the random demand.Thus,in each(ordering) period,the buyer will weigh between the current known spot price(by procuring from the spot market) and a lower future price(by waiting while consuming the remaining commitment).An optimal dual ordering policy is characterized for each period,depending on the on-hand inventory level,the spot price,and the remaining commitment quantity.The optimal policy in each period is also shown to be independent of the contract price.Through a numerical study,the inventory cost is demonstrated to be(1) insensitive to the contract price when the total commitment quantity is lower than the total expected demand over the contract period and(2) non-increasing in the variability of spot prices. | Wei ZHANG Youhua (Frank) CHEN Zhongsheng HUA Weili XUE | 2011 | Journal of Systems Science and Systems Engineering2011，20，1： | 3 |
| 10 | Lipidomics reveals carnitine palmitoyltransferase 1C protects cancer cells from lipotoxicity and senescence显示文摘Lipotoxicity, caused by intracellular lipid accumulation, accelerates the degenerative process of cellular senescence, which has implications in cancer development and therapy. Previously, carnitine palmitoyltransferase 1C(CPT1C), a mitochondrial enzyme that catalyzes carnitinylation of fatty acids, was found to be a critical regulator of cancer cell senescence. However, whether loss of CPT1C could induce senescence as a result of lipotoxicity remains unknown. An LC/MS-based lipidomic analysis of PANC-1,MDA-MB-231, HCT-116 and A549 cancer cells was conducted after siRNA depletion of CPT1C. Cellular lipotoxicity was further confirmed by lipotoxicity assays. Significant changes were found in the lipidome of CPT1C-depleted cells, including major alterations in fatty acid, diacylglycerol, triacylglycerol, oxidative lipids, cardiolipin, phosphatidylglycerol, phosphatidylcholine/phosphatidylethanolamine ratio and sphingomyelin. This was coincident with changes in expressions of mRNAs involved in lipogenesis.Histological and biochemical analyses revealed higher lipid accumulation and increased malondialdehyde and reactive oxygen species, signatures of lipid peroxidation and oxidative stress. Reduction of ATP synthesis, loss of mitochondrial transmembrane potential and down-regulation of expression of mitochondriogenesis gene m RNAs indicated mitochondrial dysfunction induced by lipotoxicity, which could further result in cellular senescence. Taken together, this study demonstrated CPT1C plays a critical role in the regulation of cancer cell lipotoxicity and cell senescence, suggesting that inhibition of CPT1C may serve as a new therapeutic strategy through induction of tumor lipotoxicity and senescence. | Huizhen Zhang Yongtao Wang Lihuan Guan Yixin Chen Panpan Chen Jiahong Sun Frank J.Gonzalez Min Huang Huichang Bi | 2021 | Journal of Pharmaceutical Analysis2021，11，3： | 3 |
| 11 | Expression Patterns of Inducible Cre Recombinase Driven by Differential Astrocyte-Specific Promoters in Transgenic Mouse Lines显示文摘Astrocytes are the most abundant cell type in the central nervous system(CNS).They provide trophic support for neurons,modulate synaptic transmission and plasticity,and contribute to neuronal dysfunction.Many transgenic mouse lines have been generated to obtain astrocyte-specific expression of inducible Cre recombinase for functional studies;however,the expression patterns of inducible Cre recombinase in these lines have not been systematically characterized.We generated a new astrocyte-specific Aldh1 l1-CreER^(T2)knock-in mouse line and compared the expression pattern of Cre recombinase between this and five widely-used transgenic lines(hGfap-CreER^(T2)from The Jackson Laboratory and The Mutant Mouse Resource and Research Center,Glast-CreER^(T2),Cx30-CreER^(T2),and Fgfr3-iCreER^(T2))by crossing with Ai14 mice,which express tdTomato fluorescence following Cre-mediated recombination.In adult Aldh1 l1-CreER^(T2):Ai 14 transgenic mice,tdTomato was detected throughout the CNS,and five novel morphologicallydefined types of astrocyte were described.Among the six evaluated lines,the specificity of Cre-mediated recombination was highest when driven by Aldh1 l1 and lowest when driven by hGfap;in the latter mice,co-staining between tdTomato and NeuN was observed in the hippocampus and cortex.Notably,evident leakage was noted in Fgfr3-iCreER^(T2)mice,and the expression level of tdTomato was low in the thalamus when Cre recombinase expression was driven by Glast and in the capsular part of the central amygdaloid nucleus when driven by Cx30.Furthermore,tdTomato was clearly expressed in peripheral organs in four of the lines.Our results emphasize that the astrocyte-specific CreER^(T2)transgenic lines used in functional studies should be carefully selected. | Neng-Yuan Hu Ya-Ting Chen Qian Wang Wei Jie Yi-Si Liu Qiang-Long You Ze-Lin Li Xiao-Wen Li Sophie Reibel Frank W.Pfrieger Jian-Ming Yang Tian-Ming Gao | 2020 | Neuroscience Bulletin2020，36，5： | 3 |

| 15 | Discussion on Performance Evaluation Method of Distributed Combined Cooling, Heating, and Power System显示文摘This paper briefly analyzed some problems and limitations of existing evaluation indicators for distributed energy system performance. Based on the diversity and difference of the energy form and grade of cooling, heating and power in the distributed combined cooling, heating, and power(CCHP) system, this paper proposed three-index evaluation system composed of key indicators including relative energy saving rate, exergy efficiency and thermoelectric ratio. In order to further prove the reasonableness and scientificity of the evaluation index system applied in performance evaluation of distributed CCHP system, it enumerated, calculated, and evaluated the energy conservation of three engineering cases. The evaluation results showed that the high energy-saving rate of the system did not mean good energy-saving, but also the efficiency of the system should be examined. Only when the energy saving rate and exergy efficiency were both high, can the energy saving performance of the system be demonstrated. When the energy-saving rate was high and the efficiency was not high, it is shown that the energy-saving of the system had great room for improvement. | SHAO Youyuan CHEN Baiman XIAO Hanmin QIN Frank G.F. | 2019 | Journal of Thermal Science2019，28，6： | 2 |

| 20 | Structural and functional basis for pan-CoV fusion inhibitors against SARS-CoV-2 and its variants with preclinical evaluation显示文摘The COVID-19 pandemic poses a global threat to public health and economy.The continuously emerging SARS-CoV-2 variants present a major challenge to the development of antiviral agents and vaccines.In this study,we identified that EK1 and cholesterol-coupled derivative of EK1,EK1C4,as pan-CoV fusion inhibitors,exhibit potent antiviral activity against SARS-CoV-2 infection in both lung-and intestine-derived cell lines(Calu-3 and Caco2,respectively).They are also effective against infection of pseudotyped SARS-CoV-2 variants B.1.1.7(Alpha)and B.l.1.248(Gamma)as well as those with mutations in S protein,including N417T,E484K,N501Y,and D614G,which are common in South African and Brazilian variants.Crystal structure revealed that EK1 targets the HR1 domain in the SARS-CoV-2 S protein to block virus-cell fusion and provide mechanistic insights into its broad and effective antiviral activity.Nasal administration of EK1 peptides to hACE2 transgenic mice significantly reduced viral titers in lung and intestinal tissues.EK1 showed good safety profiles in various animal models,supporting further clinical development of EK1-based pan-CoV fusion inhibitors against SARS-CoV-2 and its variants. | Shuai Xia Qiaoshuai Lan Yun Zhu Chao Wang Wei Xu Yutang Li Lijue Wang Fanke Jiao Jie Zhou Chen Hua Qian Wang Xia Cai Yang Wu Jie Gao Huan Liu Ge Sun Jan Munch Frank Kirchhoff Zhenghong Yuan Youhua Xie Fei Sun Shibo Jiang Lu Lu | 2021 | Signal Transduction and Targeted Therapy2021，6，8： | 2 |
