| 1 | Predictive factors associated with gefitinib response in patients with advanced non-small-cell lung cancer(NSCLC)显示文摘Purpose: A number of different clinical characteristics have been reported to singly correlate with therapeutic activity of epidermal growth factor receptor(EGFR) tyrosine kinase inhibitors(TKIs) in advanced non-small-cell lung cancer(NSCLC). This study aimed to identify predictive factors associated with prognostic benefits of gefitinib.Patients and methods: EGFR gene typing in 33 advanced NSCLC patients received gefitinib(250 mg/day) were analyzed with mutant-enriched PCR assay. Gefitinib response was evaluated with potential predictive factors retrospectively.Results: The overall objective response rate(ORR) and median progression-free survival(PFS) in the 33 patients treated by gefitinib were 45.5% and 3.0(2.0-4.0) months. The ORR and median PFS in EGFR gene mutation patients were significantly higher/longer than those in EGFR gene wild-type patients(P<0.01). Similarly, the ORR and median PFS in non-smoker patients were significantly higher/longer than those in smoker patients(P<0.05, P<0.01, respectively). However, no difference for ORR and median PFS occurred between male and female patients. Logistic multivariate analysis showed that only EGFR mutated gene was significantly associated with the ORR(P<0.01). Both EGFR mutated gene and non-smoker were the major factors that contributed to PFS(P<0.05). Conclusions: EGFR mutated gene and non-smoker status are potential predictors for gefitinib response in NSCLC patients. | Lian Chen Rui Chen Zhe Zhu Yichen Zhang Zhengwei Wen Yun Li Xiaoming Li Yuwen Luo Liyu Ma Shuguang Lin Xin Chen | 2014 | Chinese Journal of Cancer Research2014，26，4： | 7 |
| 2 | Upcycling biomass waste into Fe single atom catalysts for pollutant control显示文摘Contaminants of heavy metals and antibiotics, which are frequently detected in water, soil and food chains with increasing prevalence in our current society, can cause potential harm to human health and disrupt human ecosystem irreversibly. Herein, we have successfully utilized biomass waste ferns contaminated by iron mines, to fabricate a first-of-its-kind high-performance class of Fe single-atom catalysts(FeSAC) by a facile pyrolysis. The optimal FeSAC-800 shows an excellent efficiency in the fastphotocatalytic degradation of six types of quinolone antibiotics(e.g., norfloxacin, levofloxacin, ciprofloxacin, enrofloxacin, lomefloxacin, flumequine) in 1 h under the simulated natural light irradiation. Based on advanced characterization, a well-defined structure of FeN_(4), confined in the porous carbon is elaborated for the FeSAC-800. Mechanism of the photodegradation is via a Fenton-like oxidation process whereas the reactive oxygen species play a key role. These findings open a new avenue for efficient, sustainable utilization of biomass waste in pollutant control. | Xin Li Kang Hu Yizhe Huang Qingqing Gu Yuwen Chen Bing Yang Rongliang Qiu Wenhao Luo Bert M.Weckhuysen Kai Yan | 2022 | Journal of Energy Chemistry2022，31，6： | 3 |
| 3 | Rapid isolation and immune profiling of SARS-CoV-2 specific memory B cell in convalescent COVID-19 patients via LIBRA-seq显示文摘B cell response plays a critical role against SARS-CoV-2 infection.However,little is known about the diversity and frequency of the paired SARS-CoV-2 antigen-specific BCR repertoire after SARS-CoV-2 infection.Here,we performed single-cell RNA sequencing and VDJ sequencing using the memory and plasma B cells isolated from five convalescent COVID-19 patients,and analyzed the spectrum and transcriptional heterogeneity of antibody immune responses.Via linking BCR to antigen specificity through sequencing(LIBRA-seq),we identified a distinct activated memory B cell subgroup(CD11c^(high) CD95^(high))had a higher proportion of SARS-CoV-2 antigen-labeled cells compared with memory B cells.Our results revealed the diversity of paired BCR repertoire and the non-stochastic pairing of SARS-CoV-2 antigen-specific immunoglobulin heavy and light chains after SARS-CoV-2 infection.The public antibody clonotypes were shared by distinct convalescent individuals.Moreover,several antibodies isolated by LIBRA-seq showed high binding affinity against SARS-CoV-2 receptor-binding domain(RBD)or nucleoprotein(NP)via ELISA assay.Two RBD-reactive antibodies C14646P3S and C2767P3S isolated by LIBRA-seq exhibited high neutralizing activities against both pseudotyped and authentic SARS-CoV-2 viruses in vitro.Our study provides fundamental insights into B cell response following SARS-CoV-2 infection at the single-cell level. | Bing He Shuning Liu Yuanyuan Wang Mengxin Xu Wei Cai Jia Liu Wendi Bai Shupei Ye Yong Ma Hengrui Hu Huicui Meng Tao Sun Yanling Li Huanle Luo Mang Shi Xiangjun Du Wenjing Zhao Shoudeng Chen Jingyi Yang Haipeng Zhu Yusheng Jie Yuedong Yang Deyin Guo Qiao Wang Yuwen Liu Huimin Yan Manli Wang Yao-Qing Chen | 2021 | Signal Transduction and Targeted Therapy2021，6，6： | 2 |

| 7 | 靶向肾癌中的E3连接酶接头蛋白SPOP的小分子抑制剂显示文摘近年来肾癌发病率上升幅度在恶性肿瘤中排名第一。临床治疗表明,肾癌对放疗和化疗均不敏感,以索拉非尼和舒尼替尼为代表的靶向抗肿瘤药物是晚期肾癌的一线治疗药物,但对转移性肾癌的疗效十分有限,并且容易产生耐药。因此,发现并确证治疗肾癌特异性药物作用新靶标是一项十分紧迫并意义重大的任务。 | Zhong-Qiang Guo Tong Zheng Baoen Chen Cheng Luo Sisheng Ouyang Shouzhe Gong Jiafei Li Liu-Liang Mao Fulin Lian Yong Yang Yue Huang Li Li Jing Lu Bidong Zhang Luming Zhou Hong Ding Zhiwei Gao Liqun Zhou Guoqiang Li Ran Zhou Ke Chen Jingqiu Liu Yi Wen Likun Gong Yuwen Ke Shang-Dong Yang Xiao-Bo Qiu Naixia Zhang Jin Ren Dafang Zhong 杨财广 刘江 蒋华良 | 2017 | 科学新闻2017，19，4： | 1 |
| 8 | Strategies for improving adipose-derived stem cells for tissue regeneration显示文摘Adipose-derived stem cells(ADSCs)have promising applications in tissue regeneration.Currently,there are only a few ADSC products that have been approved for clinical use.The clinical application of ADSCs still faces many challenges.Here,we review emerging strategies to improve the therapeutic efficacy of ADSCs in tissue regeneration.First,a great quantity of cells is often needed for the stem cell therapies,which requires the advanced cell expansion technologies.In addition cell-derived products are also required for the development of‘cell-free’therapies to overcome the drawbacks of cell-based therapies.Second,it is necessary to strengthen the regenerative functions of ADSCs,including viability,differentiation and paracrine ability,for the tissue repair and regeneration required for different physiological and pathophysiological conditions.Third,poor delivery efficiency also restricts the therapeutic effect of ADSCs.Effective methods to improve cell delivery include alleviating harsh microenvironments,enhancing targeting ability and prolonging cell retention.Moreover,we also point out some critical issues about the sources,effectiveness and safety of ADSCs.With these advanced strategies to improve the therapeutic efficacy of ADSCs,ADSC-based treatment holds great promise for clinical applications in tissue regeneration. | Xin Yuan Li Li Haofan Liu Jing Luo Yongchao Zhao Cheng Pan Xue Zhang Yuwen Chen Maling Gou | 2022 | Burns & Trauma2022，10，1： | 1 |
| 9 | Promoting polysulfide conversions via cobalt single-atom catalyst for fast and durable lithium-sulfur batteries显示文摘Although promising strategies have been developed to resolve the critical drawbacks of lithium-sulfur(Li-S)batteries,the intractable issues including undesirable shuttling of polysulfides and sluggish redox reaction kinetics have still been unresolved thoroughly.Herein,a cobalt single-atom(CoSA)catalyst comprising of atomic Co distributed homogeneously within nitrogen(N)-doped porous carbon(Co-NPC)nanosphere is constructed and utilized as a separator coating in Li-S batteries.The Co-NPC exposes abundant active sites participating in sulfur redox reactions,and remarkable catalytic activity boosting the rapid polysulfide conversions.As a result,Li-S batteries with Co-NPC coating layer realize significantly enhanced specific capacity(1295 mAh·g^(-1)at 0.2 C),rate capability(753 mAh·g^(-1)at 3.0 C),and long-life cyclic stability(601 mAh·g^(-1)after 500 cycles at 1.0 C).Increasing the areal sulfur loading to 6.2 mg·cm^(-2),an extremely high areal capacity of 7.92 mAh·cm^(-2)is achieved.Further in situ X-ray diffraction,density functional theory calculations,and secondary ion mass spectrometry confirm the high catalytic capability of CoSA towards reversible polysulfide conversion.This study supplies new insights for adopting single-atom catalyst to upgrade the electrochemical performance of Li-S batteries. | Ziwei Wang Yuwen Cheng Shanying Wang Jie Xu Bo Peng Dan Luo Lianbo Ma | 2023 | Nano Research2023，16，7： | 1 |

| 14 | Antioxidant procyanidin B2 protects oocytes against cryoinjuries via mitochondria regulated cortical tension显示文摘Background:Irreversible cryodamage caused by oocyte vitrification limited its wild application in female fertility preservation.Antioxidants were always used to antagonist the oxidative stress caused by vitrification.However,the comprehensive mechanism underlying the protective role of antioxidants has not been studied.Procyanidin B2(PCB2)is a potent natural antioxidant and its functions in response to vitrification are still unknown.In this study,the effects of PCB2 on vitrified-thawed oocytes and subsequent embryo development were explored,and the mechanisms underlying the protective role of PCB2 were systematically elucidated.Results:Vitrification induced a marked decline in oocyte quality,while PCB2 could improve oocyte viability and further development after parthenogenetic activation.A subsequent study indicated that PCB2 effectively attenuated vitrification-induced oxidative stress,rescued mitochondrial dysfunction,and improved cell viability.Moreover,PCB2 also acts as a cortical tension regulator apart from strong antioxidant properties.Increased cortical tension caused by PCB2 would maintain normal spindle morphology and promote migration,ensure correct meiosis progression and finally reduce the aneuploidy rate in vitrified oocytes.Further study reveals that ATP biosynthesis plays a crucial role in cortical tension regulation,and PCB2 effectively increased the cortical tension through the electron transfer chain pathway.Additionally,PCB2 would elevate the cortical tension in embryo cells at morula and blastocyst stages and further improve blastocyst quality.What's more,targeted metabolomics shows that PCB2 has a beneficial effect on blastocyst formation by mediating saccharides and amino acids metabolism.Conclusions:Antioxidant PCB2 exhibits multi-protective roles in response to vitrification stimuli through mitochondria-mediated cortical tension regulation. | Qingrui Zhuan Jun Li Xingzhu Du Luyao Zhang Lin Meng Yuwen Luo Dan Zhou Hongyu Liu Pengcheng Wan Yunpeng Hou Xiangwei Fu | 2023 | Journal of Animal Science and Biotechnology2023，14，1： | 0 |
| 15 | Evaluation of early liquid drinking after radical gastrectomy in gastric cancer:a Chinese multicenter propensity score matching analysis显示文摘Background:Enhanced recovery after surgery is used in gastrointestinal surgery.This study aimed to access the effects of early liquid drinking(ELD)on gastrointestinal function recovery in patients with gastric cancer(GC)who underwent radical gastrectomy,as high-quality evidence on the outcomes of ELD after gastrectomy is currently lacking.Methods:Clinicopathological data of patients with GC from 11 centers were retrospectively analysed.Clinical outcomes were investigated in 555 patients,including 225 who started drinking liquid within 48 h(ELD group)of surgery and 330 who started drinking liquid after flatus resumption(traditional liquid drinking[TLD]group).Propensity score matching(PSM)analysis was performed using a match ratio of 1:1 and 201 patients were selected from each group for the analysis.Primary outcome was time to first passage of flatus.Secondary outcomes included time to first defecation,post-operative hospitalization days,occurrence of short-term post-operative complications,and hospitalization costs.Results:After PSM,baseline characteristics were not significantly different between the two groups.The time to first flatus(2.7261.08 vs 3.3661.39 days),first defecation(4.3461.85 vs 4.7761.61 days),and post-operative hospital stay(8.2764.02 vs 12.9464.43 days)were shorter in the ELD group than in the TLD group(all P<0.05).The ELD group had lower hospitalization costs than the TLD group([7.8362.44 vs 8.7863.41]104 RMB,P=0.041).No significant differences were observed in the incidence of post-operative complications.Conclusions:Compared with TLD,post-operative ELD could promote rapid recovery of gastrointestinal function and reduce hospitalization costs;moreover,ELD does not increase the risk of post-operative complications. | Yue Zhang Kaixiong Tao Jinlong Yu Chao Chen Quan Zheng Sanlin Lei Xiaogang Zhong Lixin Liu Wei Wang Qiang Wang En Li Yuwen Luo Guanrong Zhang Xingyu Feng Yong Li Junjiang Wang | 2023 | Gastroenterology Report2023，11，1： | 0 |
| 16 | Variation characteristics of acid rain in Zhuzhou,Central China over the period 2011-2020显示文摘Zhuzhou was one of the most polluted cities in China with the serious acid rain.Due to the implementation of air pollution control measures from 2016 to 2018,the acid rain pollution in this city has reduced.In order to understand the recent situation,a comprehensive study on the acid rain was carried out from January 2011 to December 2020.The pH values during the study period varied from 3.3 to 7.5,with a volume-weighted mean value of 4.7.The predominant acidic components of the precipitation were SO_(4)^(2-)and NO_(3)^(-),accounting for 89.3% of the total anions.The ratio of non-sea-salt SO_(4)^(2-)to NO_(3)^(-)showed a decreasing trend,revealing that the pollution type of acid rain changed from sulfuric acid type to sulfuric acid and nitric acid compound type.The correlation analysis(p<0.05)showed that SO_(4)^(2-)was positively correlated with NH_(4)^(+),Ca^(2+),and Mg^(2+);hence,it predominated in precipitation as(NH_(4))_(2)SO_(4),NH_(4)HSO_(4),CaSO_(4),and MgSO_(4).Significant positive correlation of Ca^(2+)with Mg^(2+)shows that they may originated mainly from crust.Significant positive correlation between SO_(4)^(2-)and F^(-)and Cl^(-)indicate that their source may be related to the non-ferrous metal smelting industry in Zhuzhou.Further correlation analysis shows that emissions from the non-ferrous metal smelting industry in the area have a large significant on SO_(4)^(2-)and F^(-)in precipitation,while Cl^(-)may still be emitted from other anthropogenic sources. | Jiahao Ren Liquan Zhu Xi Zhang Yuqian Luo Xuecai Zhong Bowen Li Yuwen Wang Kai Zhang | 2024 | Journal of Environmental Sciences2024，，4： | 0 |
| 17 | Performance Comparison of Computational Methods for the Prediction of the Function and Pathogenicity of Non-coding Variants显示文摘Non-coding variants in the human genome significantly influence human traits and complex diseases via their regulation and modification effects.Hence,an increasing number of computational methods are developed to predict the effects of variants in human non-coding sequences.However,it is difficult for inexperienced users to select appropriate computational methods from dozens of available methods.To solve this issue,we assessed 12 performance metrics of 24 methods on four independent non-coding variant benchmark datasets:(1)rare germline variants from clinical relevant sequence variants(ClinVar),(2)rare somatic variants from Catalogue Of Somatic Mutations In Cancer(COSMIC),(3)common regulatory variants from curated expression quantitative trait locus(eQTL)data,and(4)disease-associated common variants from curated genomewide association studies(GWAS).All 24 tested methods performed differently under various conditions,indicating varying strengths and weaknesses under different scenarios.Importantly,the performance of existing methods was acceptable for rare germline variants from ClinVar with the area under the receiver operating characteristic curve(AUROC)of 0.4481–0.8033 and poor for rare somatic variants from COSMIC(AUROC=0.4984–0.7131),common regulatory variants from curated eQTL data(AUROC=0.4837–0.6472),and disease-associated common variants from curated GWAS(AUROC=0.4766–0.5188).We also compared the prediction performance of 24 methods for non-coding de novo mutations in autism spectrum disorder,and found that the combined annotation-dependent depletion(CADD)and context-dependent tolerance score(CDTS)methods showed better performance.Summarily,we assessed the performance of 24 computational methods under diverse scenarios,providing preliminary advice for proper tool selection and guiding the development of new techniques in interpreting non-coding variants. | Zheng Wang Guihu Zhao Bin Li Zhenghuan Fang Qian Chen Xiaomeng Wang Tengfei Luo Yijing Wang Qiao Zhou Kuokuo Li Lu Xia Yi Zhang Xun Zhou Hongxu Pan Yuwen Zhao Yige Wang Lin Wang Jifeng Guo Beisha Tang Kun Xia Jinchen Li | 2023 | Genomics, Proteomics & Bioinformatics2023，21，3： | 0 |
| 18 | Fabrication of the Coatings for the High-temperature Oxidation Resistance on Hydrogen Resistance Steel显示文摘Alumina coating is used to improve the performance of high-temperature oxidation resistance,which can be fabricated on the surface of hydrogen resistance steel by two methods,thermal oxidation of arc ion plated Al coating and reactive magnetron sputtering.Elemental composition,structures and surface morphologies of the coating were analyzed and compared in this paper.The surface of the coatings,which was made by the first method,was composed of α-Al2O3 phase and internal was Fe-Al alloy phase.The Alumina coatings made by the second method were amorphous.In addition,appearances of Alumina coatings fabricated by these two methods were quit different,which were grey and transparent respectively.Both of the two kinds of coatings meet to the needs of high-temperature oxidation resistance. | Yang Wenmao Luo Yuwen Wu Zhiyong Li Shanzhen Li Chang'an Li Xueyuan Du Wen-Hao Chen Binzhou | 2012 | 稀有金属材料与工程2012，41，S1： | 0 |
| 19 | A prolific and robust whole-genome genotyping method using PCR amplification via primer-template mismatched annealing显示文摘Whole-genome genotyping methods are important for breeding.However,it has been challenging to develop a robust method for simultaneous foreground and background genotyping that can easily be adapted to different genes and species.In our study,we accidently discovered that in adapter ligation-mediated PCR,the amplification by primertemplate mismatched annealing(PTMA)along the genome could generate thousands of stable PCR products.Based on this observation,we consequently developed a novel method for simultaneous foreground and background integrated genotyping by sequencing(FBI-seq)using one specific primer,in which foreground genotyping is performed by primer-template perfect annealing(PTPA),while background genotyping employs PTMA.Unlike DNA arrays,multiple PCR,or genome target enrichments,FBI-seq requires little preliminary work for primer design and synthesis,and it is easily adaptable to different foreground genes and species.FBI-seq therefore provides a prolific,robust,and accurate method for simultaneous foreground and background genotyping to facilitate breeding in the postgenomics era. | Sheng Zhao Cuicui Zhang Liqun Wang Minxuan Luo Peng Zhang Yue Wang Waqar Afzal Malik Yue Wang Peng Chen Xianjin Qiu Chongrong Wang Hong Lu Yong Xiang Yuwen Liu Jue Ruan Qian Qian Haijian Zhi Yuxiao Chang | 2023 | Journal of Integrative Plant Biology2023，65，3： | 0 |
| 20 | Reduction-responsive nucleic acid nanocarrier-mediated miR-22 inhibition of PI3K/AKT pathway for the treatment of patient-derived tumor xenograft osteosarcoma显示文摘miRNAs are important regulators of gene expression and play key roles in the development of cancer, including osteosarcoma. During the development of osteosarcoma, the expression of miR-22 is significantly downregulated, making miR-22 as a promising therapeutic target against osteosarcoma. To design and fabricate efficient delivery carriers of miR-22 into osteosarcoma cells, a hydroxyl-rich reduction-responsive cationic polymeric nanoparticle, TGIC-CA (TC), was developed in this work, which also enhanced the therapeutic effects of Volasertib on osteosarcoma. TC was prepared by the ring-opening reaction between amino and epoxy groups by one-pot method, which had the good complexing ability with nucleic acids, reduction-responsive degradability and gene transfection performance. TC/miR-22 combined with volasertib could inhibit proliferation, migration and promote apoptosis of osteosarcoma cells in vitro. The anti-tumor mechanisms were revealed as TC/ miR-22 and volasertib could inhibit the PI3K/Akt signaling pathway synergistically. Furthermore, this strategy showed outstanding tumor suppression performance in animal models of orthotopic osteosarcoma, especially in patient-derived chemo-resistant and chemo-intolerant patient-derived xenograft (PDX) models, which reduced the risk of tumor lung metastasis and overcame drug resistance. Therefore, it has great potential for efficient treatment of metastasis and drug resistance of osteosarcoma by the strategy of localized, sustained delivery of miR-22 using the cationic nanocarriers combined with non-traditional chemotherapy drugs. | Dafu Chen Chengyue Lei Weifeng Liu Meiyu Shao Meizhou Sun Jianxun Guo Jingjing Cao Jing-Jun Nie Peng Luo Yuwen Luo Bingran Yu Renxian Wang Shun Duan Fu-Jian Xu | 2023 | Bioactive Materials2023，，10： | 0 |
