| 1 | Combination of anti-PD-1 antibody with P-GEMOX as a potentially effective immunochemotherapy for advanced natural killer/T cell lymphoma显示文摘Advanced natural killer/T cell lymphoma(NKTL)has demonstrated poor prognosis with currently available therapies.Here,we report the efficacy of anti-programmed death 1(PD-1)antibody with the P-GEMOX(pegaspargase,gemcitabine,and oxaliplatin)regimen in advanced NKTL.Nine patients underwent six 21-day cycles of anti-PD-1 antibody(day 1),pegaspargase 2000 U/m^(2)(day 1),gemcitabine 1 g/m^(2)(days 1 and 8)and oxaliplatin 130 mg/m^(2)(day 1),followed by anti-PD-1 antibody maintenance every 3 weeks.Programmed death-ligand 1(PD-L1)expression and genetic alterations were determined in paraffin-embedded pretreatment tissue samples using immunohistochemistry and next-generation sequencing(NGS)analysis.Responses were assessed using 18F-fluorodeoxyglucose positron emission tomography(18FDG-PET)and computed tomography or magnetic resonance imaging.Eight patients exhibited significant responses,comprising of seven complete remissions and one partial remission(overall response rate:88.9%).After a median follow-up of 10.6 months,6/9 patients(66.7%)remained in complete remission.The most common grade 3/4 adverse events were anemia(33.3%),neutropenia(33.3%),and thrombocytopenia(33.3%);all of which were manageable and resolved.Immunochemotherapy produced a high response rate in patients with positive PD-L1 expression(5/6,83.3%).NGS analysis suggested that STAT3/JAK3/PD-L1 alterations and ARID1A mutation were associated with immunochemotherapy efficacy.Mutation in DDX3X and alteration in epigenetic modifiers of KMT2D,TET2,and BCORL1 might indicate a poor response to immunochemotherapy.In conclusion,the anti-PD-1 antibody plus P-GEMOX regimen demonstrated promising efficacy in advanced NKTL.PD-L1 expression combined with specific genetic alterations could be used as potential biomarkers to predict therapeutic responses to immunochemotherapy. | Jun Cai Panpan Liu Huiqiang Huang Yajun Li Shuyun Ma Hui Zhou Xiaopeng Tian Yuchen Zhang Yan Gao Yi Xia Xuanye Zhang Hang Yang Lirong Li Qingqing Cai | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 6 |
| 2 | Primary User Adversarial Attacks on Deep Learning-Based Spectrum Sensing and the Defense Method显示文摘The spectrum sensing model based on deep learning has achieved satisfying detection per-formence,but its robustness has not been verified.In this paper,we propose primary user adversarial attack(PUAA)to verify the robustness of the deep learning based spectrum sensing model.PUAA adds a care-fully manufactured perturbation to the benign primary user signal,which greatly reduces the probability of detection of the spectrum sensing model.We design three PUAA methods in black box scenario.In or-der to defend against PUAA,we propose a defense method based on autoencoder named DeepFilter.We apply the long short-term memory network and the convolutional neural network together to DeepFilter,so that it can extract the temporal and local features of the input signal at the same time to achieve effective defense.Extensive experiments are conducted to eval-uate the attack effect of the designed PUAA method and the defense effect of DeepFilter.Results show that the three PUAA methods designed can greatly reduce the probability of detection of the deep learning-based spectrum sensing model.In addition,the experimen-tal results of the defense effect of DeepFilter show that DeepFilter can effectively defend against PUAA with-out affecting the detection performance of the model. | Shilian Zheng Linhui Ye Xuanye Wang Jinyin Chen Huaji Zhou Caiyi Lou Zhijin Zhao Xiaoniu Yang | 2021 | China Communications2021，18，12： | 3 |
| 3 | Similar or different: the same Spiro-core but different alkyl chains with apparently improved device performance of perovskite solar cells显示文摘By intelligently utilizing the odd-even effect existing in the melting points of alkanes as presented in the basic textbook of Organic Chemistry, different alkoxy groups were introduced to modify the structure of commercial Spiro-OMeTAD to give new Spiro derivatives of Spiro-OEtTAD, Spiro-OPrTAD, Spiro-OiPrTAD and Spiro-OBuTAD, with the aim to adjust the molecular packing status in perovskite solar cells as hole transporting compounds. Excitedly, with the introduction of ethoxy groups instead of the methoxy ones in Spiro-OMeTAD, Spiro-OEtTAD-based perovskite solar cells demonstrated the highest device performance of 20.16%, higher than that of Spiro-OMeTAD(18.64%). | Fan Liu Shiqing Bi Xiaorui Wang Xuanye Leng Mengmeng Han Baoda Xue Qianqian Li Huiqiong Zhou Zhen Li | 2019 | Science China Chemistry2019，62，6： | 2 |

| 5 | Off-farm employment,agriculture production activities,and household dietary diversity in environmentally and economically vulnerable areas of Asia显示文摘Access to off-farm employment has been expected to be a critical approach to ending hunger and all forms of malnutrition,two important targets of achieving Zero Hunger.This study aims to investigate the role of off-farm employment in improving dietary diversity through substitution effect and complementary effect with agricultural production activities and income effect.This study adopts Poisson/Tobit/Probit/OLS regressions and the instrument variable method based on the primary survey data collected among 1,282 households at 12 sites in environmentally and economically vulnerable areas of China,Nepal,Cambodia,Thailand,and Myanmar in 2019.The results show that off-farm employment is positively associated with household dietary diversity and the consumption of flesh meat,fish and other aquatic animals,fruits,and milk and dairy products,which are rich in protein and micronutrients.The results of mechanism analysis show that off-farm employment contributes to household dietary diversity by improving crop diversity,especially for poor households,boosting the probability of livestock raising for households with the middle one-third disposal income,and increasing household income.The positive association between off-farm employment and household dietary diversity is much higher for households with the bottom one-third disposal income,low illiteracy,and from upper-middle income countries.These findings imply that off-farm employment does play a vital role in achieving multiple benefits of poverty alleviation,malnutrition reduction,and agrobiodiversity conservation in environmentally and economically vulnerable areas.However,it may enlarge the gaps in dietary diversity between households with low human capital and from low and lower-middle income countries and those with high human capital and from middle-high countries. | Yunli Bai Xuanye Zeng Chao Fu Linxiu Zhang | 2024 | Journal of Integrative Agriculture2024，23，2： | 1 |

| 7 | A model for anticancer surveillance was pharmacologically developed to evaluate vitality principle in breast cancer rats显示文摘OBJECTIVE: To evaluate vitality principle in breast cancer rats by pharmacologically developing a model for anticancer surveillance.METHODS: The breast cancer in rats was replicated with 7,12-Dimethylbenz[a]anthracene(DMBA, i.g.,100 mg/kg) at d_(001). The anticancer surveillance was defined as the intervals between the primary sensitization and the first challenge stirred with complete Freund's adjuvant(CFA), the various intervals(k = 0.80) were dominated from d_(025)(600.00 h) to d_(095)(2288.82 h). The optimal surveillant status was confirmed with the median effective interval(EI_(50))from tumor volume regressive curve, for developing the pharmacodynamic model. The tumor and tumor infiltrating lymphocyte histopathology was used to confirm the immune surveillance being affected with CFA in breast cancer tumorigenesis.The availability of this model was confirmed with Shugan Liangxue prescription(SLP), from the vitality principle, and assured further from interleukin-12 levels.RESULTS: The regressive curve was set up between the intervals and tumor volumes, the EI_(50) in SLP-treated rats(1475.00 h, Y_(SLP)= 0.1026 +0.8780/[1 + 10^(27.1425-8.565x)]) was postponed, which was 1.87 multiple of the EI_(50) in CFA rats(791.40 h, y =-0.0525 + 0.9452/[1 + 10^(30.4870-10.52x)], so did prepone the curve between the intervals and the immunological biomarker, serum interleukin-12 levels, the EI_(50) in SLP-treated rats(744.90 h, Y_(SLP)=-0.0145 + 0.7455/[1 + 10^(52.09636-18.13x)]) be 0.78 multiple of the EI_(50) in CFA rats(960.10 h, Y_(CFA)= 0.2460 + 0.7270/[1 + 10^(-67.1546 +22.52x)]), this immunological action being mediated the anticancer prognosis. Tumor histology was confirmed the more tumor infiltrating lymphocytes activated in SLP rats with CFA stirred immunity than rats only received CFA.CONCLUSION: The model for anticancer surveillance was pharmacologically established as the optimal interval(791.40 h) between the primary sensitization and the first challenge stirred with complete Freund's adjuvant. This available model was confirmed with SLP, from the vitality principle, for evaluating immunological effects against breast cancer. | Liu Jinyu Zhang Mengyang Zhao Xin Ge Shasha Li Shuang Peng Lin Mu Yuxue Chen Chen Li Xiaoya Zhang Rui Feng Xuanye Deng Bo Jia Liqun Lin Yulin Wang Yueqi Cheng Zhiqiang TaeHoo Yi Cai Dayong | 2018 | Journal of Traditional Chinese Medicine2018，38，6： | 0 |
| 8 | CO hydrogenation on stepped Cu and CuZn alloy surfaces:Competition between methanol synthesis and methanation pathways显示文摘Comprehensive fundamental understanding of CO hydrogenation reactions over Cu and ZnCu alloy surfaces is of great importance.Herein,we report a comparative DFT calculation study of elementary surface reaction network of CO hydrogenation reactions on stepped Cu(211),Cu(611),ZnCu(211) and ZnCu(611)surfaces.On Zn Cu(211) and Zn Cu(611) surfaces,the energetic favorable reaction path of CO hydrogenation reaction follows CO^(*)→HCO^(*)→H_(2)CO^(*)→H_(3)CO^(*)→CH_(3)OH^(*)→CH_(3)OH with H_(3)CO^(*)hydrogenation as the rate-limiting step and proceeds more facilely on ZnCu(611) surface than on ZnCu(211) surface.On Cu(211) and Cu(611) surfaces,the energetic favorable reaction path of CO hydrogenation reaction follows CO^(*)→HCO^(*)→HCOH^(*)→H_(2)COH^(*)→H_(3)COH^(*)→CH_(3)^(*)→CH_(4)^(*)→CH_(4) with H_(2)COH^(*) hydrogenation as the rate-limiting step and proceeds more facilely on Cu(611) than on Cu(211).The key difference of CO hydrogenation reaction on Zn Cu alloy surface and Cu is that the resulting CH_(3)OH^(*) species desorbs to produce CH_(3)OH on ZnCu alloy but undergoes H^(*)-assisted decomposition to CH_(3)^(*) and eventually to CH_(4) on Cu surface.These results successfully unveil elementary surface reaction networks and structure sensitivity of Cu and Zn Cu alloy-catalyzed CO hydrogenation reactions. | Xuanye Chen Wenhua Zhang Weixin Huang | 2023 | Chinese Chemical Letters2023，34，7： | 0 |

| 10 | Homozygous Mutation in the MTHFS Gene May Contribute to the Development of Cerebral Folate Deficiency Syndrome显示文摘Objective:The purpose of this study was to examine the role of rare variants in the one-carbon metabolic pathway in the etiology of the cerebral folate deficiency(CFD)syndrome.The CFD syndrome is a neurometabolic syndrome identified by low concentrations of 5-methyltetrahydrofolate(5-MTHF)in the cerebrospinal fluid(CSF)in spite of near-normal peripheral folate levels resulting in neurodevelopmental disorders.Methods:The localized folate metabolism impairments in CFD are thought to be either the result of mutations in genes responsible for folate transport or folate turnover through degradation.Genes that have been previously implicated in the etiology of CFD include folate receptor alpha-1(FOLR1),dihydrofolate reductase,proton-coupled folate transporter,and capicua.We performed whole-exome sequencing(WES)analysis of a CFD patient that revealed 99 novel missense mutations,of which 21 were classified as damaging mutations through the Poly-Phen2 prediction algorithm.In vitro functional studies were conducted by transient transfection of wild-type and mutant MTHFS into HEK293T cells to determine the impact of the variants on enzyme activity.Results:Of the damaging variants identified in the WES studies,we focused on the gene coding for the enzyme 5,10-methenyl-tetrahydrofolate synthetase(MTHFS).This enzyme catalyzes the production of methenyl THF which is subsequently converted to 5-MTHF.The CFD patient described within was found to carry a homozygous mutation,c.101G>T(p.R34L,rs200058464)in MTHFS,while the parents of the proband are heterozygotes for the MTHFS gene,and the healthy sibling is not a carrier.Conclusion:The mutant allele displayed a 50%reduction in luciferase activity(P<0.05),suggesting that homozygous loss of the MTHFS gene may play a significant role in the development of CFD. | Dharaniya Sakthivel Yunping Lei Xuanye Cao Richard H.Finnell | 2020 | Reproductive and Developmental Medicine2020，4，2： | 0 |
| 11 | Active copper structures in ZnO–Cu interfacial catalysis:CO_(2) hydrogenation to methanol and reverse water–gas shift reactions显示文摘Cu–ZnO-based catalysts are widely used to catalyze the CO_(2) hydrogenation to methanol and reverse water–gas shift(RWGS)reactions.Herein,via a combined experimental and theoretical calculation study of various Cu nanocrystals(NCs) with welldefined Cu facets and corresponding Zn O/Cu NC inverse catalysts,we demonstrate the Cu{110} facets as the most active facet for ZnO–Cu interfacial catalysis in the CO_(2) hydrogenation to methanol with an apparent activation energy as low as 25.3±3 kJ mol^(-1) and the Cu{100} facets as the most active facet for both ZnO–Cu interfacial catalysis and Cu catalysis in the RWGS reaction.Although the ZnO–Cu interface is more active in catalyzing the RWGS reaction than the Cu surface,the RWGS reaction occurs mainly on the bare Cu surface of ZnO/Cu inverse catalysts under the CO_(2) hydrogenation to methanol instead of that at the ZnO–Cu interface.This fundamental understanding will greatly help to fabricate efficient Cu–ZnO-based catalysts for the CO_(2) hydrogenation to methanol. | Wei Xiong Zongfang Wu Xuanye Chen Jieqiong Ding Aiai Ye Wenhua Zhang Weixin Huang | 2024 | Science China Chemistry2024，67，2： | 0 |
