| 2 | Allogeneic Vγ9Vδ2 T-cell immunotherapy exhibits promising clinical safety and prolongs the survival of patients with late-stage lung or liver cancer显示文摘Vγ9Vδ2 T cells are promising candidates for cellular tumor immunotherapy.Due to their HLA-independent mode of action,allogeneic Vγ9Vδ2 T cells can be considered for clinical application.To apply allogeneic Vγ9Vδ2 T cells in adoptive immunotherapy,the methodology used to obtain adequate cell numbers with optimal effector function in vitro needs to be optimized,and clinical safety and efficacy also need to be proven.Therefore,we developed a novel formula to improve the expansion of peripheralγδT cells from healthy donors.Then,we used a humanized mouse model to validate the therapeutic efficacy of expandedγδT cells in vivo;furthermore,the expandedγδT cells were adoptively transferred into late-stage liver and lung cancer patients.We found that the expanded cells possessed significantly improved immune effector functions,including proliferation,differentiation,and cancer cell killing,both in vitro and in the humanized mouse model.Furthermore,a phase I clinical trial in 132 late-stage cancer patients with a total of 414 cell infusions unequivocally validated the clinical safety of allogeneic Vγ9Vδ2 T cells.Among these 132 patients,8 liver cancer patients and 10 lung cancer patients who received≥5 cell infusions showed greatly prolonged survival,which preliminarily verified the efficacy of allogeneic Vγ9Vδ2 T-cell therapy.Our clinical studies underscore the safety and efficacy of allogeneic Vγ9Vδ2 T-cell immunotherapy,which will inspire further clinical investigations and eventually benefit cancer patients. | Yan Xu Zheng Xiang Mohammed Alnaggar Léonce Kouakanou Jiawei Li Junyi He Jiashuang Yang Yi Hu Yan Chen Li Lin Jianlei Hao Jingxia Li Jibing Chen Man Li Qingling Wu Christian Peters Qinghua Zhou Jianshuang Li Yingqing Liang Xiaohua Wang Baohui Han Meili Ma Dieter Kabelitz Kecheng Xu Wenwei Tu Yangzhe Wu Zhinan Yin | 2021 | Cellular & Molecular Immunology2021，18，2： | 8 |
| 3 | A genome-wide analysis of SWEET gene family in cotton and their expressions under different stresses显示文摘Background: The SWEET(Sugars will eventually be exported transporters) gene family plays multiple roles in plant physiological activities and development process. It participates in reproductive development and in the process of sugar transport and absorption, plant senescence and stress responses and plant-pathogen interaction. However,thecomprehensive analysis of SWEET genes has not been reported in cotton.Results: In this study, we identified 22, 31, 55 and 60 SWEET genes from the sequenced genomes of Gossypium arboreum, G. raimondii, G. hirsutum and G. barbadense, respectively. Phylogenetic tree analysis showed that the SWEET genes could be divided into four groups, which were further classified into 14 sub-clades. Further analysis of chromosomal location, synteny analysis and gene duplication suggested that the orthologs showed a good collinearity and segmental duplication events played a crucial role in the expansion of the family in cotton. Specific MtN3_slv domains were highly conserved between Arobidopsis and cotton by exon-intron organization and motif analysis. In addition, the expression pattern in different tissues indicated that the duplicated genes in cotton might have acquired new functions as a result of sub-functionalization or neo-funtionalization. The expression pattern of SWEET genes showed that the different genes were induced by diverse stresses. The identification and functional analysis of SWEET genes in cotton may provide more candidate genes for genetic modification.Conclusion: SWEET genes were classified into four clades in cotton. The expression patterns suggested that the duplicated genes might have experienced a functional divergence. This work provides insights into the evolution of SWEET genes and more candidates for specific genetic modification, which will be useful in future research. | ZHAO Lanjie YAO Jinbo CHEN Wei LI Yan L Youjun GUO Yan WANG Junyi YUAN Li LIU Ziyang ZHANG Yongshan | 2018 | Journal of Cotton Research2018，1，2： | 6 |
| 4 | The use of fire at Zhoukoudian:evidence from magnetic susceptibility and color measurements显示文摘In order to provide direct evidence for the use of fire by humans at Locality 1,Zhoukoudian,we examine the burnt and unburnt sediments of newly excavated area in Layer 4 by detailed measurements of magnetic susceptibility,color,and diffuse reflectance spectrum.Results show that the magnetic susceptibility and redness of the burnt sediments are remarkably higher than those of other areas on the same level:up to*22 times for magnetic susceptibility and*3 times for redness of those of the adjacent unburnt sediments.Fine-grained(superparamagnetic/stable single-domain)magnetite and hematite grains make dominant contributions to the distinctly high values of magnetic susceptibility and redness in the burnt sediments.Diffuse reflectance spectroscopy results show that the burnt sediments contain more hematite than those of other areas and localities 2 and 3.High-temperature magnetic susceptibility measurements demonstrate that the burnt sediments have been heated above 700°C.Those changes in low-frequency magnetic susceptibility and redness are impossibly resulted from natural fires,thus most likely signaling the human activities of controlled use of fire.However,further work is needed to confirm whether or not these heat-affected sediments were produced in situ. | Yan Zhang Zhengtang Guo Chenglong Deng Shuangquan Zhang Haibin Wu Chunxia Zhang Junyi Ge Deai Zhao Qin Li Yang Song Rixiang Zhu | 2014 | Chinese Science Bulletin2014，59，10： | 6 |
| 5 | A new distinct geminivirus causes soybean stay-green disease显示文摘Dear Editor,Plant viruses make up almost half of the plant disease-causing pathogens,affecting crop yields and the global economy(Savary et al.,2019).Soybean(Glycine max)is one of the most valuable legume crops in the world,supplying 25%of the global edible oil and two-thirds of the global concentrated protein for livestock feeding.Recently,the outbreak of soybean stay-green syndrome with delayed leaf senescence(stay-green),flat pods,and increased number of abnormal seeds has swept the soybean production in the Huang-Huai-Hai region of China,resulting in huge yield losses(Xu et al.,2019).This disease has become an epidemic and prominent problem in soybean production and is still expanding its geography,including North America,posing a serious threat to soybean production(Harbach et al.,2016;Zhang et al.,2016;Li et al.,2019).However,the cause of soybean stay-green syndrome remains obscure. | Ruixiang Cheng Ruoxin Mei Rong Yan Hongyu Chen Dan Miao Lina Cai Jiayi Fan Gairu Li Ran Xu Weiguo Lu Yu Gao Wenwu Ye Shuo Su Tianfu Han Junyi Gai Yuanchao Wang Xiaorong Tao Yi Xu | 2022 | Molecular Plant2022，15，6： | 6 |

| 7 | An all-round AI-Chemist with a scientific mind显示文摘The realization of automated chemical experiments by robots unveiled the prelude to an artificial intelligence(AI)laboratory.Several AI-based systems or robots with specific chemical skills have been demonstrated,but conducting all-round scientific research remains challenging.Here,we present an all-round AI-Chemist equipped with scientific data intelligence that is capable of performing basic tasks generally required in chemical research.Based on a service platform,the AI-Chemist is able to automatically read the literatures from a cloud database and propose experimental plans accordingly.It can control a mobile robot in-house or online to automatically execute the complete experimental process on 14 workstations,including synthesis,characterization and performance tests.The experimental data can be simultaneously analysed by the computational brain of the AI-Chemist through machine learning and Bayesian optimization,allowing a new hypothesis for the next iteration to be proposed.The competence of the AI-Chemist has been scrutinized by three different chemical tasks.In the future,the more advanced all-round AI-Chemists equipped with scientific data intelligence may cause changes to the landscape of the chemical laboratory. | Qing Zhu Fei Zhang Yan Huang Hengyu Xiao LuYuan Zhao XuChun Zhang Tao Song XinSheng Tang Xiang Li Guo He BaoChen Chong JunYi Zhou YiHan Zhang Baicheng Zhang JiaQi Cao Man Luo Song Wang GuiLin Ye WanJun Zhang Xin Chen Shuang Cong Donglai Zhou Huirong Li Jialei Li Gang Zou WeiWei Shang Jun Jiang Yi Luo | 2022 | National Science Review2022，9，10： | 5 |
| 8 | Is new American Thyroid Association risk classification for hereditary medullary thyroid carcinoma applicable to Chinese patients? A single-center study显示文摘Objective: The American Thyroid Association(ATA) proposed a new risk classification for hereditary medullary thyroid carcinoma(MTC) in 2015. This study aimed to assess whether the new guidelines are suitable for the Chinese population, and reported our experience on prophylactic thyroidectomy.Methods: A total of 73 patients from 22 families were screened as rearranged during transfection(RET) mutation carriers from 2010 to 2016 in Cancer Hospital, Chinese Academy of Medical Science; the medical history for each patient was collected. Based on the initial treatment, we identified the risk factors for poor prognosis by univariate and multivariate logistic regression. Then, 4 RET mutation carriers were enrolled for prophylactic thyroidectomy,and their pathological data and follow-up outcomes were recorded.Results: In univariate and multivariate logistic regression analyses, age at initial surgery and risk classification were significant risk factors for stage Ⅲ/Ⅳ hereditary MTC at initial diagnosis. The likelihood was increased by 11.6% per year of age at initial surgery [95% confidence interval(95% CI), 1.040–1.198; P=0.002). It was 7.888 times more likely to have Ⅲ/Ⅳ stage disease for ATA highest risk patients, compared to ATA moderate risk individuals(95% CI, 1.607–38.717; P=0.003). Postoperative pathological results showed all 4 multiple endocrine neoplasia type 2A(MEN2A) patients had C-cell hyperplasia(CCH); multifocal malignancies were detected in 3 of them. All 4 patients were cured biochemically, and none developed permanent hypoparathyroidism.Conclusions: In Chinese individuals, hereditary MTC aggressiveness is in line with the new ATA risk classification. Germline RET gene mutation carriers should undergo prophylactic thyroidectomy according to basal serum calcitonin levels. | Xiwei Zhang Dangui Yan Junyi Wang Hanfeng Wan Yongxia Zhang Yabing Zhang Yuqin He Wensheng Liu Bin Zhang | 2017 | Chinese Journal of Cancer Research2017，29，3： | 5 |
| 9 | Exploration of presence/absence variation and corresponding polymorphic markers in soybean genome显示文摘This study was designed to reveal the genome‐wide distribution of presence/absence variation(PAV) and to establish a database of polymorphic PAV markers in soybean. The 33 soybean whole‐genome sequences were compared to each other with that of Williams 82 as a reference genome. A total of 33,127 PAVs were detected and 28,912 PAV markers with their primer sequences were designed as the database NJAUSoyPAV_1.0. The PAVs scattered on whole genome while only 518(1.8%) overlapped with simple sequence repeats(SSRs) in BARCSOYSSR_1.0database. In a random sample of 800 PAVs, 713(89.13%) showed polymorphism among the 12 differential genotypes. Using 126 PAVs and 108 SSRs to test a Chinese soybean germplasm collection composed of 828 Glycine soja Sieb. et Zucc. and Glycine max(L.) Merr. accessions, the per locus allele number and its variation appeared less in PAVs than in SSRs. The distinctness among alleles/bands of PCR(polymerase chain reaction) products showed better in PAVs than in SSRs, potential in accurate marker‐assisted allele selection. The association mapping results showed SSR t PAV was more powerful than any single marker systems.The NJAUSoyPAV_1.0 database has enriched the source of PCR markers, and may fit the materials with a range of per locus allele numbers, if jointly used with SSR markers. | Yufeng Wang Jiangjie Lu Shouyi Chen Liping Shu Reid G.Palmer Guangnan Xing Yan Li Shouping Yang Deyue Yu Tuanjie Zhao Junyi Gai | 2014 | Journal of Integrative Plant Biology2014，56，10： | 5 |

| 12 | Bidirectional turbo equalization for underwater acoustic communications显示文摘A direct-adaptation based bidirectional turbo equalizer for underwater acoustic communications is proposed.Abandoning the channel estimation process,the direct-adaptation based turbo equalizer embedded with digital phase-locked loop is adopted to track time-varying channel.The fast self-optimized algorithm is used to adjust the step size,thus a good tradeoff between the convergence speed and performance has been made.Furthermore,by minimizing the mean squared error,an optimal weighting factor is derived to exploit bidirectional diversity gain.The forward turbo equalizer is combined with the backward turbo equalizer to eliminate error propagation effect.Simulated and experimental results demonstrate that the bidirectional turbo equalizer outperforms the single directional one.It can be seen from the experimental results that,compared with the channel estimation based algorithm,the direct-adaptation based algorithm is less sensitive to the time-varying channel and has a lower bit error rate. | XI Junyi YAN Shefeng XU Lijun TIAN Jing | 2016 | Chinese Journal of Acoustics2016，35，4： | 4 |
| 13 | Prevalence and clinical significance of pathogenic germline BRCA1/2 mutations in Chinese non-small cell lung cancer patients显示文摘Objective: Germline alterations in the breast cancer susceptibility genes type 1 and 2, BRCA1 and BRCA2, predispose individuals to hereditary cancers, including breast, ovarian, prostate, pancreatic, and stomach cancers.Accumulating evidence suggests inherited genetic susceptibility to lung cancer.The present study aimed to survey the prevalence of pathogenic germline BRCA mutations(gBRCAm) and explore the potential association between gBRCAm and disease onset in Chinese advanced non-small cell lung cancer(NSCLC) patients.Methods: A total of 6,220 NSCLC patients were screened using capture-based ultra-deep targeted sequencing to identify patients harboring germline BRCA1/2 mutations.Results: Out of the 6,220 patients screened, 1.03%(64/6,220) of the patients harbored the pathogenic gB RCAm, with BRCA2 mutations being the most predominant mutations(49/64, 76.5%).Patients who developed NSCLC before 50 years of age were more likely to carry gBRCAm(P = 0.036).Among the patients harboring classic lung cancer driver mutations, those with concurrent gBRCAm were significantly younger than those harboring the wild-type gBRCA(P = 0.029).By contrast, the age of patients with or without concurrent gBRCAm was comparable to those of patients without the driver mutations(P = 0.972).In addition, we identified EGFR-mutant patients with concurrent gBRCAm who showed comparable progression-free survival but significantly longer overall survival(P = 0.002) compared to EGFR-mutant patients with wild-type germline BRCA.Conclusions: Overall, our study is the largest survey of the prevalence of pathogenic gBRCAm in advanced Chinese NSCLC patients.Results suggested a lack of association between germline BRCA status and treatment outcome of EGFR-TKI.In addition,results showed a positive correlation between pathogenic gB RCAm and an early onset of NSCLC. | Xingsheng Hu Dongyong Yang Yalun Li Li Li Yan Wang Peng Chen Song Xu Xingxiang Pu Wei Zhu Pengbo Deng Junyi Ye Hanhan Zhang Analyn Lizaso Hao Liu Xinru Mao Hai Huang Qian Chu Chengping Hu | 2019 | Cancer Biology & Medicine2019，16，3： | 4 |
| 14 | Vitamin C promotes the proliferation and effector functions of human γδ T cells显示文摘γδT cells are of interest as effector cells for cellular immunotherapy due to their HLA-non-restricted lysis of many different tumor cell types.Potential applications include the adoptive transfer of in vitro-expandedγδT cells.Therefore,it is important to optimize the culture conditions to enable maximal proliferative and functional activity.Vitamin C(L-ascorbic acid)is an essential vitamin with multiple effects on immune cells.It is a cofactor for several enzymes,has antioxidant activity,and is an epigenetic modifier.Here,we investigated the effects of vitamin C(VC)and its more stable derivative,L-ascorbic acid 2-phosphate(pVC),on the proliferation and effector function of humanγδT cells stimulated with zoledronate(ZOL)or synthetic phosphoantigens(pAgs).VC and pVC did not increaseγδT-cell expansion within ZOL-or pAg-stimulated PBMCs,but increased the proliferation of purifiedγδT cells and 14-day-expandedγδT-cell lines in response toγδT-cell-specific pAgs.VC reduced the apoptosis ofγδT cells during primary stimulation.While pVC did not prevent activation-induced death of pAg-restimulatedγδT cells,it enhanced the cell cycle progression and cellular expansion.Furthermore,VC and pVC enhanced cytokine production during primary activation,as well as upon pAg restimulation of 14-day-expandedγδT cells.VC and pVC also increased the oxidative respiration and glycolysis ofγδT cells,but stimulus-dependent differences were observed.The modulatory activity of VC and pVC might help to increase the efficacy ofγδT-cell expansion for adoptive immunotherapy. | Léonce Kouakanou Yan Xu Christian Peters Junyi He Yangzhe Wu Zhinan Yin Dieter Kabelitz | 2020 | Cellular & Molecular Immunology2020，17，5： | 3 |

| 16 | Soft Direct-Adaptation Based Bidirectional Turbo Equalization for MIMO Underwater Acoustic Communications显示文摘This paper proposes a soft direct-adaptation based bidirectional turbo equalizer for multiple-input multiple-output underwater acoustic communication systems. Soft, rather than hard, direct-adaptation based equalizer combined with the fast self-optimized least mean square algorithm is employed to achieve a faster convergence rate, and the second-order phase-locked loop is embedded into the equalizer to track the time-varying channel. Meanwhile, by utilizing a weighted linear combining scheme, the conventional soft direct-adaptation based equalizer is combined with the time-reversed soft direct-adaptation based equalizer to exploit bidirectional diversity and mitigate error propagation. Both the simulation and experimental results demonstrate that the soft direct-adaptation based bidirectional turbo equalizer outperforms the single-direction soft direct-adaptation based turbo equalizer, and achieves a faster convergence rate than the hard direct-adaptation based bidirectional turbo equalizer. | Junyi Xi Shefeng Yan Lijun Xu Jing Tian | 2017 | China Communications2017，14，7： | 3 |

| 18 | Cytoplasmic and nuclear genome variations of rice hybrids and their parents inform the trajectory and strategy of hybrid rice breeding显示文摘The male sterility(MS)line is a prerequisite for efficient production of hybrid seeds in rice,a self-pollinating species.MS line breeding is pivotal for hybrid rice improvement.Understanding the historical breeding tra-jectory will help to improve hybrid rice breeding strategies.Maternally inherited cytoplasm is an appro-priate tool for phylogenetic reconstruction and pedigree tracing in rice hybrids.In this study,we analyzed the cytoplasmic genomes of 1495 elite hybrid rice varieties and identified five major types of cytoplasm,which correspond to different hybrid production systems.As the cytoplasm donors for hybrids,461 MS lines were also divided into five major types based on cytoplasmic and nuclear genomic architecture.Spe-cific core accessions cooperating with different fertility-associated genes drove the sequence divergence of MS lines.Dozens to hundreds of convergent and divergent selective sweeps spanning several agro-nomic trait-associated genes were identified among different types of MS lines.We further analyzed the cross patterns between different types of MS lines and their corresponding restorers.This study system-atically analyzed the cytoplasmic genomes of rice hybrids revealed their relationships with nuclear ge-nomes of MS lines,and illustrated the trajectory of hybrid rice breeding and the strategies for breeding different types of MS lines providing new insights for future improvement of hybrid rice. | Zhoulin Gu Zhou Zhu Zhen Li Qilin Zhan Qi Feng Congcong Zhou Qiang Zhao Yan Zhao Xiaojian Peng Bingxin Dai Rongrong Sun Yan Li Hengyun Lu Lei Zhang Tao Huang Junyi Gong Danfeng Lv Xuehui Huang Bin Han | 2021 | Molecular Plant2021，14，12： | 2 |
| 19 | Tidal currents in the coastal waters east of Hainan Island in winter显示文摘Using the 25-h continuing hydrographic observations at three successive stations in February 2012 and the mooring time series of current observations from January to March 2015,the tidal currents and tidal energy fluxes in the coastal waters east of Hainan Island in the northwestern South China Sea were analyzed.The diurnal and semidiurnal(using K_(1) and M_(2) as proxies,respectively)tidal currents and associated isopycnal undulations were derived with harmonic analysis.Results show that the velocities of the diurnal and semidiurnal tides derived from the 25-h observations are comparable to those from the mooring series.The semi-major axes of the tidal ellipses were O(4-7 cm/s)for barotropic tides and O(2-4 cm/s)for baroclinic tides.The directions were in NE-SW at deeper stations to N-S at the shallowest station for the diurnal tide and from NW-SE to NE-SW for the semidiurnal tide.Both the diurnal and semidiurnal isopycnal fl uctuations reached O(5 m),O(8 m),and O(10 m)at the cross-shelf stations(H03,H04,and H05)from 35 m,45 m,to 55 m,respectively,showing insignifi cant vertical variation,and the barotropic signals were predominate.The baroclinic diurnal tide showed fi rst-mode structures at H03-05,as does the semidiurnal tide at H03.The semidiurnal tide at H04 and H05 exhibited higher-mode structures.The time series of both the alongshore and cross-shore components reveal the vertically propagation features of the baroclinic tidal phase and energy.The calculated horizontal energy fl uxes of the diurnal and semidiurnal internal tides decreased from O(0.1 W/m)at H05 to O(0.01 W/m)at H03,implying a propagation and dissipation of energy from off shore to inshore. | Min LI Lingling XIE Xiaolong ZONG Junyi LI Mingming LI Tong YAN Ronglei HAN | 2022 | Journal of Oceanology and Limnology2022，40，2： | 2 |
| 20 | Decadal-scale variability of warm season temperature in Beijing over the past 2650 years显示文摘A continuous record of surface temperature for the past 2650 years was obtained in an earlier study from a Beijing stalagmite based on sedimentary layer counting and thickness measurements.Singular spectrum analysis,multi-taper and wavelet spectral analyses are used in this study to identify decadal-scale signals and their origins in this record.Besides long-term cycles of solar origin identified in earlier studies,this record contains cycles that dominate temperature with periods of 102-70,66-50,31,25-22,19,15,12 and 9 years.The 102-70,25-22,12 and 9 year cycles are attributable to solar variation,while the others are likely to be related to low-latitude ocean forcing.These results suggest that century-scale changes in the Beijing summer temperature over the past 2650 years are primarily controlled by solar variation,while ocean-atmospheric interactions play a prominent role in modu-lating decadal-scale variability. | DAI Ying ZHANG Yan GE JunYi | 2011 | Chinese Science Bulletin2011，56，22： | 2 |
