| 1 | Application of next-generation sequencing technology to precision medicine in cancer: joint consensus of the Tumor Biomarker Committee of the Chinese Society of Clinical Oncology显示文摘Next-generation sequencing(NGS) technology is capable of sequencing millions or billions of DNA molecules simultaneously.Therefore, it represents a promising tool for the analysis of molecular targets for the initial diagnosis of disease, monitoring of disease progression, and identifying the mechanism of drug resistance. On behalf of the Tumor Biomarker Committee of the Chinese Society of Clinical Oncology(CSCO) and the China Actionable Genome Consortium(CAGC), the present expert group hereby proposes advisory guidelines on clinical applications of NGS technology for the analysis of cancer driver genes for precision cancer therapy. This group comprises an assembly of laboratory cancer geneticists, clinical oncologists, bioinformaticians,pathologists, and other professionals. After multiple rounds of discussions and revisions, the expert group has reached a preliminary consensus on the need of NGS in clinical diagnosis, its regulation, and compliance standards in clinical sample collection. Moreover, it has prepared NGS criteria, the sequencing standard operation procedure(SOP), data analysis, report, and NGS platform certification and validation. | Xuchao Zhang Zhiyong Liang Shengyue Wang Shun Lu Yong Song Ying Cheng Jianming Ying Weiping Liu Yingyong Hou Yangqiu Li Yi Liu Jun Hou Xiufeng Liu Jianyong Shao Yanhong Tai Zheng Wang Li Fu Hui Li Xiaojun Zhou Hua Bai Mengzhao Wang You Lu Jinji Yang Wenzhao Zhong Qing Zhou Xuening Yang Jie Wang Cheng Huang Xiaoqing Liu Xiaoyan Zhou Shirong Zhang Hongxia Tian Yu Chen Ruibao Ren Ning Liao Chunyan Wu Zhongzheng Zhu Hongming Pan Yanhong Gu Liwei Wang Yunpeng Liu Suzhan Zhang Tianshu Liu Gong Chen Zhimin Shao Binghe Xu Qingyuan Zhang Ruihua Xu Lin Shen Yilong Wu | 2019 | Cancer Biology & Medicine2019，16，1： | 14 |
| 2 | Immunomodulatory 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 | 2019 | Acta Biochimica et Biophysica Sinica2019，51，8： | 14 |
| 3 | Detection of geosmin and 2-methylisoborneol by liquid-liquid extraction-gas chromatograph mass spectrum (LLE-GCMS) and solid phase extraction-gas chromatograph mass spectrum (SPE-GCMS)显示文摘Two sample preparation methods were introduced and compared in this paper to establish a simple,quick and exact analysis of geosmin and 2-methylisoborneol.LC-18 column was employed in solid phase extraction(SPE),1.0 mL of hexane was adopted in liquid-liquid extraction(LLE),and the extracts were analyzed by gas chromatograph mass spectrum(GCMS)in selected ion mode.Mean recoveries of SPE were low for 2-methylisoborneol(2-MIB)and geosmin(GSM)with values below 50%.For LLE,the recoveries were satisfyingly above 50%for 2-MIB and 80%for GSM.Detection limits of the LLE method were as low as 1.0 ng/L for GSM and 5.0 ng/L for 2-MIB.A year-long investigation on odor chemicals of drinking water in Shanghai demonstrated that in the summer,there was a serious odor problem induced by a high concentration of 2-MIB.The highest concentration of 152.82 ng/L appeared in July in raw water,while GSM flocculation was minimal with concentrations below odor threshold. | MA Xiaoyan GAO Naiyun CHEN Beibei LI Qingsong ZHANG Qiaoli GU Guofen | 2007 | Frontiers of Environmental Science & Engineering2007，1，3： | 7 |
| 4 | A new Monte Carlo simulation of three-dimensional microstructures and their evolution in polycrystalline显示文摘A new Monte Carlo simulation method for studying three-dimensional microstructures as well as their evolution in polycrystalline materials has been set up. The algorithm is simple and flexible to apply. With the present method, kinetics of three-dimensional grain growth is accurately reflected and the simulation efficiency is greatly improved. The simulation can not only be used reliably to analyze quantitatively the microstructures and their evolution, but also be used conveniently to observe microstructures as well as their evolution on the horizontal section and the sections at any angle to the horizontal plane, to measure the characteristic parameters in three dimensions and cross-sections, together with their relationships between the two systems, and to many other aspects. | Xiaoyan Song Guoquan Liu Nanju Gu | 1999 | Chinese Science Bulletin1999，44，15： | 6 |
| 5 | Optical observations of LIGO source GW 170817 by the Antarctic Survey Telescopes at Dome A,Antarctica显示文摘The LIGO detection of gravitational waves(GW) from merging black holes in 2015 marked the beginning of a new era in observational astronomy. The detection of an electromagnetic signal from a GW source is the critical next step to explore in detail the physics involved. The Antarctic Survey Telescopes(AST3),located at Dome A, Antarctica, is uniquely situated for rapid response time-domain astronomy with its continuous night-time coverage during the austral winter. We report optical observations of the GW source(GW 170817) in the nearby galaxy NGC 4993 using AST3. The data show a rapidly fading transient at around 1 day after the GW trigger, with the i-band magnitude declining from 17:23 ± 0:13 magnitude to 17:72 ± 0:09 magnitude in ~1:8 h. The brightness and time evolution of the optical transient associated with GW 170817 are broadly consistent with the predictions of models involving merging binary neutron stars. We infer from our data that the merging process ejected about ~10^(-2) solar mass of radioactive material at a speed of up to 30% the speed of light. | lei hu xuefeng wu igor andreoni michael c.b.ashley jeff cooke xiangqun cui fujia du zigao dai bozhong gu yi hu haiping lu xiaoyan li zhengyang li ensi liang liangduan liu bin ma zhaohui shang tianrui sun n.b.suntzeff charling tao syed a.uddin lifan wang xiaofeng wang haikun wen di xiao jin xu ji yang shihai yang xiangyan yuan hongyan zhou hui zhang jilin zhou zonghong zhu | 2017 | Science Bulletin2017，62，21： | 6 |
| 6 | Microelectronics-embedded channel bridging and signal regeneration of injured spinal cords显示文摘Due to the dificulty in spinal cord regeneration with biological methods,the microelectronic neural bridge,a new concept based on microelectronic technology,is presented.The microelectronic system has been realized in the forms of hybrid and integrated circuits.The integrated circuits forneural signal detection,stimulation,and regeneration are realized in a CMOS process.In animal experiments with 100 toads,48 rats,and 3 rabbits,nerve signals have been successfully detected from spinal cords and sciatic nerves,and functional electrical stimulation has been carried out for spinal cords and sciatic nerves.When the microelectronic system is bridged between the controlling and stimulated nerve,the relevant motion of legs and nerve signal waveforms,which are stimulated by the evoked or spontaneous nerve signal through such a system,have been observed.Therefore,the feasibility of the presented method was demonstrated. | Zhigong Wang Xiaosong Gu Xiaoying Lǔ Zhenglin Jiang Wenyuan Li Guangming Lǔ Yufeng Wang Xiaoyan Shen Xintai Zhao Huiling Wang Zhenyu Zhang Hongmei Shen Yang Wu Weixing Shen Jingyang Zhang Dong Chen Xiaoyi Mao Huaxiang Shen | 2009 | Progress in Natural Science:Materials International2009，19，10： | 5 |

| 8 | Peptidome analysis of human intrauterine adhesion tissues and the identification of antifibrotic peptide显示文摘Intrauterine adhesion(IUA)is a common clinical endometrial disease,which can severely damage the fertility and quality of life in women.This study aims to find the differentially expressed endogenous peptides and their possible roles in IUA.Liquid chromatography-mass spectrometry was used to identify the peptidomic profiling of IUA tissues,and the differentially expressed peptides were screened out.Using real-time quantitative PCR,Western blotting,and immunocytochemistry staining,the function of six endogenous peptides was verified in vitro.It was found that peptide 6(T6)(peptide sequence:TFGGAPGFPLGSPLSSVFPR)could inhibit the expression of TGF-β1-induced cell fibrosis in human endometrial stromal cell line and primary human endometrial stromal cell at a concentration of 50μmol/L.This study provides new targets for further clarifying the formation and prevention of IUA. | Xiangdong Hua Yan Zhang Juan Xu Lu Xu Yaqian Shi Dazhen Yang Xiaoyan Gu Sumin Wang Xuemei Jia Feng Xu Jie Chen Xiaoyan Ying | 2022 | The Journal of Biomedical Research2022，36，4： | 3 |
| 9 | Trp_(548)Met mutation of acetolactate synthase in rice confers resistance to a broad spectrum of ALS-inhibiting herbicides显示文摘Herbicide resistance in crop plants is valuable for integrated weed management in agriculture. Herbicide resistant rice, in particular, is important to management of weedy rice, a close relative of cultivated rice and a noxious weed prevalent in rice fields that remains challenging to farmers worldwide. Herbicide resistant plants can be obtained through transgenic approach or by mutagenesis of regular plant and screening of mutants with elevated resistance to herbicide. In this study, we conducted ethyl methyl sulfonate mutagenesis(EMS) to elite indica cultivar Huanghuazhan(HHZ) and screened for mutants resistant to imazapic, a herbicide that can inhibit the acetolactate synthase(ALS) in plants. We obtained three mutants of Os ALS gene that have not been reported previously in rice. One of the mutants, with Trp_(548) changed to Met(W_(548)M), was analyzed in more details in this study. This mutation had no negative effect on the plant physiology and morphology as well as rice yield. Compared with the imidazolinone-resistant mutant S_(627)N(Ser_(627) changed to Asn) that has been deployed for Clearfield rice development, W_(548)M mutant showed high levels of resistance to a broad spectrum of five families of ALSinhibiting herbicides, in addition to a higher level of resistance to herbicides of the imidazolinone family.The herbicide-resistance was stably inherited by crossing into other rice lines. Thus, the W_(548)M mutation provides a valuable resource for breeding of herbicide resistant rice and weed management. | Lei Chen Gang Gu Chengxu Wang Zhufeng Chen Wei Yan Man Jin Gang Xie Junli Zhou Xing Wang Deng Xiaoyan Tang | 2021 | The Crop Journal2021，9，4： | 3 |
| 10 | Intestinal dysbiosis exacerbates the pathogenesis of psoriasis-like phenotype through changes in fatty acid metabolism显示文摘The intestinal microbiota has been associated with host immunity as well as psoriasis;however,the mechanism of intestinal microbiota regulating psoriasis needs to be demonstrated systematically.Here,we sought to examine its role and mechanism of action in the pathogenesis of psoriasis.We found that the severity of psoriasis-like skin phenotype was accompanied by changes in the composition of the intestinal microbiota.We performed co-housing and fecal microbial transplantation(FMT)experiments using the K14-VEGF transgenic mouse model of psoriasis and demonstrated that the transfer of intestinal microbiota from mice with severe psoriasis-like skin phenotype exacerbated psoriasiform skin inflammation in mice with mild symptoms,including increasing the infiltration and differentiation of Th17,and increased the abundance of Prevotella,while decreasing that of Parabacteroides distasonis,in the colon.These alterations affected fatty acid metabolism,increasing the abundance of oleic and stearic acids.Meanwhile,gentamicin treatment significantly reduced the abundance of Prevotella and alleviated the psoriasis-like symptoms in both K14-VEGF mice and imiquimod(IMQ)-induced psoriasis-like mice.Indeed,administration of oleic and stearic acids exacerbated psoriasis-like symptoms and increased Th17 and monocyte-derived dendritic cell infiltration in the skin lesion areas in vivo,as well as increased the secretion of IL-23 by stimulating DCs in vitro.At last,we found that,treatment of PDE-4 inhibitor alleviated psoriasis-like phenotype of K14-VEGF mice accompanied by the recovery of intestinal microbiota,including the decrease of Prevotella and increase of Parabacteroides distasonis.Overall,our findings reveal that the intestinal microbiota modulates host metabolism and psoriasis-like skin inflammation in mice,suggesting a new target for the clinical diagnosis and treatment of psoriasis. | Qixiang Zhao Jiadong Yu Hong Zhou Xiaoyan Wang Chen Zhang Jing Hu Yawen Hu Huaping Zheng Fanlian Zeng Chengcheng Yue Linna Gu Zhen Wang Fulei Zhao Pei Zhou Haozhou Zhang Nongyu Huang Wenling Wu Yifan Zhou Jiong Li | 2023 | Signal Transduction and Targeted Therapy2023，8，2： | 2 |

| 12 | Development of the novel ACLY inhibitor 326E as a promising treatment for hypercholesterolemia显示文摘Hepatic cholesterol accumulation is an important contributor to hypercholesterolemia,which results in atherosclerosis and cardiovascular disease(CVD).ATP-citrate lyase(ACLY)is a key lipogenic enzyme that converts cytosolic citrate derived from tricarboxylic acid cycle(TCA cycle)to acetyl-CoA in the cytoplasm.Therefore,ACLY represents a link between mitochondria oxidative phosphorylation and cytosolic de novo lipogenesis.In this study,we developed the small molecule 326E with an enedioic acid structural moiety as a novel ACLY inhibitor,and its CoA-conjugated form 326E-CoA inhibited ACLY activity with an IC_(50)=5.31±1.2μmol/L in vitro.326E treatment reduced de novo lipogenesis,and increased cholesterol efflux in vitro and in vivo.326E was rapidly absorbed after oral administration,exhibited a higher blood exposure than that of the approved ACLY inhibitor bempedoic acid(BA)used for hypercholesterolemia.Chronic 326E treatment in hamsters and rhesus monkeys resulted in remarkable improvement of hyperlipidemia.Once daily oral administration of 326E for 24 weeks prevented the occurrence of atherosclerosis in ApoE^(-/-)mice to a greater extent than that of BA treatment.Taken together,our data suggest that inhibition of ACLY by 326E represents a promising strategy for the treatment of hypercholesterolemia. | Zhifu Xie Mei Zhang Qian Song Long Cheng Xinwen Zhang Gaolei Song Xinyu Sun Min Gu Chendong Zhou Yangming Zhang Kexin Zhu Jianpeng Yin Xiaoyan Chen Jingya Li Fajun Nan | 2023 | Acta Pharmaceutica Sinica B2023，13，2： | 1 |
| 13 | Genome-wide signatures of the geographic expansion and breeding of soybean显示文摘Soybean is a leguminous crop that provides oil and protein. Exploring the genomic signatures of soybean evolution is crucial for breeding varieties with improved adaptability to environmental extremes. We analyzed the genome sequences of 2,214 soybeans and proposed a soybean evolutionary route, i.e., the expansion of annual wild soybean(Glycine soja Sieb. & Zucc.) from southern China and its domestication in central China, followed by the expansion and local breeding selection of its landraces(G. max(L.) Merr.). We observed that the genetic introgression in soybean landraces was mostly derived from sympatric rather than allopatric wild populations during the geographic expansion. Soybean expansion and breeding were accompanied by the positive selection of flowering time genes, including GmSPA3c. Our study sheds light on the evolutionary history of soybean and provides valuable genetic resources for its future breeding. | Ying-Hui Li Chao Qin Li Wang Chengzhi Jiao Huilong Hong Yu Tian Yanfei Li Guangnan Xing Jun Wang Yongzhe Gu Xingpeng Gao Delin Li Hongyu Li Zhangxiong Liu Xin Jing Beibei Feng Tao Zhao Rongxia Guan Yong Guo Jun Liu Zhe Yan Lijuan Zhang Tianli Ge Xiangkong Li Xiaobo Wang Hongmei Qiu Wanhai Zhang Xiaoyan Luan Yingpeng Han Dezhi Han Ruzhen Chang Yalong Guo Jochen C.Reif Scott A.Jackson Bin Liu Shilin Tian Li-juan Qiu | 2023 | Science China(Life Sciences)2023，66，2： | 1 |

| 17 | rbcL Gene Sequencing of Several Species Belonging to Morus and Their Genetic Relationship显示文摘[Objective] The paper was to sequence the rbc L gene of several species belonging to Morus, and to explore the genetic relationship of Morus plants. [Method] Through DNA extraction, PCR amplification, sequencing, splicing and correction, a total of 56 rbc L gene sequences were obtained. [Result] Alignment results showed that there were 1 279 permutation sites in rbc L sequence of Morus plants; variable sites accounted for6.8% of the total sequence length, and the ratio of transition pairs to transversion pairs(R= si/sv) was 1.2. The rbc L sequence of Broussonetia papyrifera was selected as the outgroup, which was downloaded from Gen Bank. Genetic analysis results showed that M. alba, M. notabilis, M. rubra and Kuisang(the sample of this study) had distant relationship, and the other Morus plants had relatively close relationship. [Conclusion] The results lay a foundation for selection, identification and classification of Morus plants. | Lv Jinfeng Zhou Chan Zeng Xiu Wang Yongliang Wang Jieping Wang Haiyan Gu Shanlin Wang Xiaoyan | 2018 | Animal Husbandry and Feed Science2018，10，3： | 1 |

| 19 | Anti-infection effects of heparin on SARS-CoV-2 in a diabetic mouse model显示文摘Severe acute respiratory syndrome coronavirus 2(SARSCo V-2)infection can result in more severe syndromes and poorer outcomes in patients with diabetes and obesity.However,the precise mechanisms responsible for the combined impact of coronavirus disease 2019(COVID-19)and diabetes have not yet been elucidated,and effective treatment options for SARS-Co V-2-infected diabetic patients remain limited.To investigate the disease pathogenesis,K18-h ACE2 transgenic(h ACE2^(Tg))mice with a leptin receptor deficiency(h ACE2-Lepr^(-/-))and high-fat diet(h ACE2-HFD)background were generated.The two mouse models were intranasally infected with a 5×10^(5) median tissue culture infectious dose(TCID_(50))of SARSCo V-2,with serum and lung tissue samples collected at 3days post-infection.The h ACE2-Lepr^(-/-)mice were then administered a combination of low-molecular-weight heparin(LMWH)(1 mg/kg or 5 mg/kg)and insulin via subcutaneous injection prior to intranasal infection with1×10^(4) TCID_(50)of SARS-Co V-2.Daily drug administration continued until the euthanasia of the mice.Analyses of viral RNA loads,histopathological changes in lung tissue,and inflammation factors were conducted.Results demonstrated similar SARS-Co V-2 susceptibility in h ACE2^(Tg)mice under both lean(chow diet)and obese(HFD)conditions.However,compared to the h ACE2-Lepr^(+/+)mice,h ACE2-Lepr^(-/-)mice exhibited more severe lung injury,enhanced expression of inflammatory cytokines and hypoxia-inducible factor-1α(HIF-1α),and increased apoptosis.Moreover,combined LMWH and insulin treatment effectively reduced disease progression and severity,attenuated lung pathological changes,and mitigated inflammatory responses.In conclusion,preexisting diabetes can lead to more severe lung damage upon SARS-Co V-2 infection,and LMWH may be a valuable therapeutic approach for managing COVID-19patients with diabetes. | Zhongyun Zhang Ning Zhang Xuancheng Lu Min Zhou Xiaoxiang Yan Weiqiong Gu Jingru Yang Qin Zhang Cheng Zhang Yuhuan Gong Mingjun Jia Xiaoyu Zhang Peng Ning Mei Liu Xiaoyan Li Xiaomeng Shi Wenjun Liu George FGao Guang Ning Jiqiu Wang Yuhai Bi | 2023 | Zoological Research2023，44，6： | 1 |
| 20 | Multiplexed imaging of tumor immune microenvironmental markers in locally advanced or metastatic non-small-cell lung cancer characterizes the features of response to PD-1 blockade plus chemotherapy显示文摘Background:Although programmed cell death 1(PD-1)blockade plus chemotherapy can significantly prolong the progression-free survival(PFS)and overall survival(OS)in first-line settings in patients with driver-negative advanced non-small-cell lung cancer(NSCLC),the predictive biomarkers remain undetermined.Here,we investigated the predictive value of tumor immune microenvironmental marker expression to characterize the response features to PD-1 blockade plus chemotherapy.Methods:Tumor tissue samples at baseline were prospectively collected from 144 locally advanced or metastatic NSCLC patients without driver gene alterations who received camrelizumab plus chemotherapy or chemotherapy alone.Tumor immune microenvironmental markers,including PD-1 ligand(PDL1),CD8,CD68,CD4 and forkhead box P3,were assessed using multiplex immunofluorescence(mIF)assays.Kaplan-Meier curveswere used to determine treatment outcome differences according to their expression status.Mutational profiles were compared between tumors with distinct expression levels of these markers and their combinations.Results:Responders had significantly higher CD8/PD-L1(P=0.015)or CD68/PD-L1 co-expression levels(P=0.021)than non-responders in the camrelizumab plus chemotherapy group,while no difference was observed in the chemotherapy group.Patients with high CD8/PD-L1 or CD68/PD-L1 co-expression level was associated with significantly longer PFS(P=0.002,P=0.024;respectively)and OS(P=0.006,P=0.026;respectively)than those with low co-expression in camrelizumab plus chemotherapy group.When comparing survival in the camrelizumab plus chemotherapy with chemotherapy by CD8/PD-L1 co-expression stratification,significantly better PFS(P=0.003)and OS(P=0.032)were observed in high co-expression subgroups.The predictive value of CD8/PD-L1 and CD68/PD-L1 co-expression remained statistically significant for PFS and OS when adjusting clinicopathological features.Although the prevalence of TP53 or KRAS mutations was similar between patients with and without CD8/PD-L1 or CD68/PD-L1 co-expression,the positive groups had a significantly higher proportion of TP53/KRAS co-mutations than the negative groups(both 13.0%vs.0.0%,P=0.023).Notably,enriched PI3K(P=0.012)and cell cycle pathway(P=0.021)were found in the CD8/PD-L1 co-expression group.Conclusion:Tumor immune microenvironmental marker expression,especially CD8/PD-L1 or CD68/PD-L1 co-expression,was associated with the efficacy of PD-1 blockade plus chemotherapy as first-line treatment in patients with advanced NSCLC. | Fengying Wu Tao Jiang Gongyan Chen Yunchao Huang Jianying Zhou Lizhu Lin Jifeng Feng Zhehai Wang Yongqian Shu Jianhua Shi Yi Hu Qiming Wang Ying Cheng Jianhua Chen Xiaoyan Lin Yongsheng Wang Jianan Huang Jiuwei Cui Lejie Cao Yunpeng Liu Yiping Zhang Yueyin Pan Jun Zhao LiPing Wang Jianhua Chang Qun Chen Xiubao Ren Wei Zhang Yun Fan Zhiyong He Jian Fang Kangsheng Gu Xiaorong Dong Tao Zhang Wei Shi Jianjun Zou Xuejuan Bai Shengxiang Ren Caicun Zhou | 2022 | Cancer Communications2022，42，12： | 1 |
