| 1 | Southern rice black-streaked dwarf virus:A new proposed Fijivirus species in the family Reoviridae显示文摘For the past several years, a novel dwarf disease has been observed on rice (Oryza sativa) in some regions of Guangdong Province and Hainan Province, southern China. Infected plants showed stunting, dark leaf and small enations on stem and leaf back. Typical Fijivirus viroplasma containing crystalline arrayed spherical virons approximately 70―75 nm in diameter and tubular structures were detected in ultrathin sections by an electron microscope in parenchyma phloem cells of the infected plants. The virus was transmitted to rice seedlings by white-backed planthoppers, Sogatella furcifera (Hemiptera: Delphacidae), collected in the diseased fields. Analysis of dsRNA extracts from infected plants revealed ten linear segments, which were similar to the electrophoretic profile of Rice black-streaked dwarf virus (RBSDV). RT-PCR with a single primer which matched to a linker sequence ligated to both 3′ ends of the viral genomic dsRNAs resulted in amplification of genome segments 9 (S9) and 10 (S10) cDNA products. The complete nucleotide sequences of S9 and S10 were obtained from clones of the RT-PCR amplicon exhibited characteristic properties of Fijivirus including low GC content (34.5% and 35.6%), genus conserved 5′ and 3′ termini sequences and similar genome organization. Blast searches indicated that the sequences of S9 and S10 shared 68.8%―74.9% and 67.1%―77.4% nucleotide identities with those of viruses in the Fijivirus group 2, respectively. These values were similar to those among other viruses in the Fijivirus group 2 and considerably lower than those among RBSDV isolates. Phylogenetic trees based on S9 and S10 nucleotide sequences and their putative amino acid sequences showed that this virus represented a separate branch among other Fijiviruses. The virus was also detected by a nested RT-PCR assay in corn (Zea mays), barnyard grass (Echinochloa crusgalli), Juncellus serotinus and flaccidgrass (Pennisetum flaccidum) in and/or adjacent to the infected rice fields. It is proposed that this virus be considered as a new species, Southern rice black-streaked dwarf virus, in the group 2 of the genus Fijivirus in the family Reoviridae. | ZHOU GuoHui WEN JingJung CAI DeJiang LI Peng XU DongLin ZHANG ShuGuang | 2008 | Chinese Science Bulletin2008，53，23： | 124 |
| 2 | A complete sequence and comparative analysis of a SARS-associated virus(Isolate BJ01)显示文摘The genome sequence of the Severe Acute Respiratory Syndrome (SARS)-associated virus provides essential information for the identification of pathogen(s), exploration of etiology and evolution, interpretation of transmission and pathogenesis, development of diagnostics, prevention by future vaccination, and treatment by developing new drugs. We report the complete genome sequence and comparative analysis of an isolate (BJ01) of the coronavirus that has been recognized as a pathogen for SARS. The genome is 29725 nt in size and has 11 ORFs (Open Reading Frames). It is composed of a stable region encoding an RNA-dependent RNA polymerase (composed of 2 ORFs) and a variable region representing 4 CDSs (coding sequences) for viral structural genes (the S, E, M, N proteins) and 5 PUPs (putative uncharacterized proteins). Its gene order is identical to that of other known coronaviruses. The sequence alignment with all known RNA viruses places this virus as a member in the family of Coronaviridae. Thirty putative substitutions have been identified by comparative analysis of the 5 SARS- associated virus genome sequences in GenBank. Fifteen of them lead to possible amino acid changes (non-synonymous mutations) in the proteins. Three amino acid changes, with predicted alteration of physical and chemical features, have been detected in the S protein that is postulated to beinvolved in the immunoreactions between the virus and its host. Two amino acid changes have been detected in the Mprotein, which could be related to viral envelope formation. Phylogenetic analysis suggests the possibility of non-human origin of the SARS-associated viruses but provides noevidence that they are man-made. Further efforts should focus on identifying the etiology of the SARS-associated virus and ruling out conclusively the existence of otherpossible SARS-related pathogen(s). | QIN E'de ZHU Qingyu YU Man FAN Baochang CHANG Guohui SI Bingyin YANG Bao PENG Wenming JIANG Tao LIU Bohua DENG Yongqiang LIU Hong ZHANG Yu WANG Cui LI Yuquan GAN Yonghua LI Xiaoyu L Fushuang TAN Gang CAO Wuchun, YANG Ruifu Institute of Microbiology and Epidemiology, Chinese Academy of Military Medical Sciences, Beijing 100071, China WANG Jian, LI Wei, XU Zuyuan, LI Yan, WU Qingfa, LIN Wei, CHEN Weijun, TANG Lin, DENG Yajun, HAN Yujun, LI Changfeng, LEI Meng, LI Guoqing, LI Wenjie, L Hong, SHI Jianping, TONG Zongzhong, ZHANG Feng, LI Songgang, LIU Bin, LIU Siqi, DONG Wei, WANG Jun, Gane K-S Wong, YU Jun & YANG Huanming* Beijing Genomics Institute, Chinese Academy of Sciences, Beijing 101300 National Center for Genome Information, Beijing 101300, China | 2003 | Chinese Science Bulletin2003，48，10： | 121 |
| 3 | The fractal characteristic change in the Huanghe River Estuary due to the hydrodynamic conditions’variation显示文摘The study area lies in the subaqueous delta, which came into being in 1964~1976. One oil-field road has been built for exploring petroleum to form a wave barrier. The hydrodynamic conditions on the north side of the road are relatively violent, on the contrary the hydrodynamic conditions on the south side of the road are nearly placid. This makes the study area a natural laboratory for studying the influence of the hydrodynamic conditions on the fractal characteristics of the tidal flat. Selecting an area is named Case Ⅰ on the side of stronger hydrodynamic activities and an area is named Case Ⅱ on the other side. Measuring the topography and sampling and analyzing the granulometrical composition, it is found that the hydrodynamic conditions have fatal influence on the surface fractal dimensions and the granulometrical fractal dimensions of the area. In Case Ⅰ, which has strong hydrodynamic conditions, the surface fractal dimensions are obviously larger than those of Case Ⅱ, and the granulometrical fractal dimensions are relatively smaller than those of Case Ⅱ, the surface fractal dimensions of Case Ⅰ decrease quickly with the increase of grid size; the granulometrical fractal dimensions are disperse, while the hydrodynamic conditions of Case Ⅱ are just reverse. A sampling line and a core sampling on each side of the road are selected. It is found that on the south side of the road the granulometrical fractal dimensions vary regularly in the line and with the depth, the farther apart from the road, the smaller the fractal dimensions, and the deeper the sampling position the larger the fractal dimensions, while granulometrical fractal dimensions on the north side of the road have no such regularity pattern. The mechanism of the influence of the hydrodynamic conditions on the fractal characteristics is discussed. | Jia Yonggang, Fu Yuanbin, Xu Guohui, Shan Hongxian, Cao Xueqing Environmental Engineering Department, Ocean University of China, Qingdao 266003,China | 2003 | Acta Oceanologica Sinica2003，22，2： | 13 |
| 4 | Outcomes in refractory diffuse large B-cell lymphoma:results fromamulticenter real-world study in China显示文摘Background:Diffuse large B-cell lymphoma(DLBCL)patients refractory to rituximab-based immunochemotherapy have a dismal prognosis.However,the definition of refractory DLBCL remains inconsistent and no large cohort study data is available from Asian countries.To validate the definition and outcomes of refractory DLBCL in China,we conducted a multicenter,retrospective cohort study.Methods:The REtrospective AnaLysis of Treatment REspoNse of refractory DLBCL(REAL-TREND)study was performed using real-world data from 8 centers in China.DLBCL patients with curative intent were included in the REAL-TREND dataset.Overall survival(OS)was estimated using the Kaplan-Meier method and compared by the log-rank test.Due to heterogeneity in response rates among different centers,the response rates of refractory patients were pooled using random-effect models.Multivariate survival analysis was performed using the Cox regression model.Results:A total of 2778 DLBCL patients diagnosed between January,2010 and December,2015 were enrolled to this study.After validating previous definitions,the SCHOLAR-1 study was most suitable to define refractory DLBCL.The estimated 5-year cumulative incidence of refractory patients was 20%(95% confidence Interval[CI]=18%-22%).After the determination of refractory disease,overall response rate and complete remission rate were 30%(95%CI=22%-38%)and 9%(95%CI=4%-15%),respectively.Patients with either no response to immunochemotherapy or relapse within 12 months after stem-cell transplantation had inferior survival with a median OS of 5.9 months(95%CI=5.5-7.1 months)and 2-year OS rate of 16%(95%CI=12%-20%).International prognostic index score 4-5(hazard ratio[HR]=2.22;95%CI=1.47-3.35),central nervous systemrelapse(HR=1.43;95%CI=1.04-1.97),and best response status(HR=2.68;95%CI=1.42-5.03 for partial remission.HR=5.97,95%CI=3.21-11.11 for stable disease/progressive disease)were independent unfavorable prognostic factors.Conclusions:This is the first large-scale Asian cohort study focusing on outcomes of refractory DLBCL.The definition of the SCHOLAR-1 study identifies patients with homogenously inferior survival,thus is appropriate to select refractory DLBCL.Due to poor clinical outcomes in the rituximab era,patients with refractory DLBCL may be potential candidates for novel treatment modalities. | Shuo Wang Li Wang Jianda Hu Wenbin Qian Xi Zhang Yu Hu Qi Zhu Bobin Chen Depei Wu Chung-Chou H.Chang Pengpeng Xu Xiaoyun Zheng Juying Wei Yao Liu Guohui Cui Yong Tang Yan Ma Haiwen Huang Hongmei Yi Weili Zhao | 2021 | Cancer Communications2021，41，3： | 10 |
| 5 | Nucleocytoplasmic Trafficking of the Arabidopsis WD40 Repeat Protein XIW1 Regulates ABI5 Stability and Abscisic Acid Responses显示文摘WD40 repeat-containing proteins(WD40 proteins)serve as versatile scaffolds for protein-protein interac-tions,modulating a variety of cellular processes such as plant stress and hormone responses.Here we report the identification of a WD40 protein,XIW1(for XPO1-interacting WD40 protein 1),which positively regulates the abscisic acid(ABA)response in Arabidopsis.XIW1 is located in the cytoplasm and nucleus.We found that it interacts with the nuclear transport receptor XPO1 and is exported by XPO1 from the nucleus.Mutation of XIW1 reduces the induction of ABA-responsive genes and the accumulation of ABA Insensitive 5(ABI5),causing mutant plants with ABA-insensitive phenotypes during seed germination and seedling growth,and decreased drought stress resistance.ABA treatment upregulates the expression of XIW1,and both ABA and abiotic stresses promote XIW1 accumulation in the nucleus,where it interacts with ABI5.Loss of XIW1 function results in rapid proteasomal degradation of ABI5.Taken together,these findings suggest that XIW1 is a nucleocytoplasmic shuttling protein and plays a positive role in ABA responses by interacting with and maintaining the stability of ABI5 in the nucleus. | Xuezhong XU Wang Wan Guobin Jiang Yue Xi Haijian Huang Jiajia Cai Yanan Chang Cheng-Guo Duan Satendra KMangrauthia Xinxiang Peng Jian-Kang Zhu Guohui Zhu | 2019 | Molecular Plant2019，12，12： | 8 |
| 6 | Mammography combined with breast dynamic contrast-enhanced-magnetic resonance imaging for the diagnosis of early breast cancer显示文摘Objective The aim of this study was to investigate the application of mammography combined with breast dynamic contrast-enhanced magnetic resonance imaging(DCE-MRI) for the diagnosis of early breast cancer. Methods Mammography and DCE-MRI were performed for 120 patients with breast cancer(malignant, 102; benign; 18). Results The sensitivity of mammography for early diagnosis of breast cancer was 66.67%, specificity was 77.78%, and accuracy was 68.33%. The sensitivity of MRI for early diagnosis of breast cancer was 94.12%, specificity was 88.89%, and accuracy was 93.33%. However, the sensitivity of mammography combined with DCE-MRI volume imaging with enhanced water signal(VIEWS) scanning for early diagnosis of breast cancer was 97.06%, specificity was 94.44%, and accuracy was 96.67%. Conclusion Mammography combined with DCE-MRI increased the sensitivity, specificity, and accuracy of diagnosing early breast cancer. | Yakun He Guohui Xu Jin Ren Bin Feng Xiaolei Dong Hao Lu Changjiu He | 2016 | Oncology and Translational Medicine2016，2，4： | 4 |
| 7 | The Bethesda System for Reporting Thyroid Cytopathology(TBSRTC):A report of 2,781 cases in a Chinese population显示文摘Objective:To evaluate the diagnostic utility of The Bethesda System for Reporting Thyroid Cytology(TBSRTC)at Peking University Cancer Hospital,the incidence of noninvasive follicular thyroid neoplasms with papillary-like nuclear features(NIFTP),and the impact of reclassification on cytopathological outcomes.Methods:We performed a retrospective study of thyroid fine-needle aspiration(FNA)cases between April 2014 and March 2019.The FNA results were classified according to TBSRTC.Post-surgery histological findings were followed up.Results:A total of 2,781 thyroid FNAs were performed.The incidences of the 6 diagnostic categories(DCs I-VI)were 14.8%,17.1%,15.8%,2.3%,11.6%and 38.5%,respectively.A total of 1,122 patients(40.3%)had corresponding histological results.NIFTP accounted for 0.4%of papillary thyroid carcinoma(PTC)cases,and there was no significant difference in the risk of malignancy(ROM)for each TBSRTC DC between'NIFTP=carcinoma(Ca)'and'NIFTP≠Ca'.When'NIFTP=Ca',the sensitivity,specificity,positive predictive value(PPV),negative predictive value(NPV),and accuracy of TBSRTC were 98.0%,84.0%,99.4%,58.3%,and97.5%,respectively.When'NIFTP≠Ca',the sensitivity,specificity,PPV,NPV and accuracy of the TBSRTC were 98.1%,81.5%,99.3%,61.1%,and 97.5%,respectively.Conclusions:TBSRTC is effective in the preoperative diagnosis of thyroid nodules in Peking University Cancer Hospital.The impact of the reclassification of NIFTP on cytopathological outcomes is limited because of its low incidence,and the revised ROMs are not suitable for Asian patients. | Yanli Zhu Yuntao Song Guohui Xu Zhihui Fan Wenhao Ren | 2020 | Chinese Journal of Cancer Research2020，32，2： | 4 |
| 8 | Rapid growth of a large-scale(600 mm aperture) KDP crystal and its optical quality显示文摘Potassium dihydrogen phosphate(KDP) single crystals are the only nonlinear crystals currently used for electro-optic switches and frequency converters in inertial confinement fusion research, due to their large dimension and exclusive physical properties. Based on the traditional solution-growth process, large bulk KDP crystals, usually with sizes up to600 × 600 mm2 so as to make a frequency doubler for the facility requirement loading highly flux of power laser, can be grown in standard Holden-type crystallizers, without spontaneous nucleation and visible defects, one to two orders of magnitude faster than by conventional methods. Pure water and KDP raw material with a few ion impurities such as Fe,Cr, and Al(less than 0.1 ppm) were used. The rapid-growth method includes extreme conditions such as temperature range from 60 to 35℃ , overcooling up to 5℃ , growth rates exceeding 10 mm/day, and crystal size up to 600 mm. The optical parameters of KDP crystals were determined. The optical properties of crystals determined indicate that they are of favorable quality for application in the facility. | Guohui Li Guozong Zheng Yingkun Qi Peixiu Yin En Tang Fei Li Jing Xu Taiming Lei Xiuqin Lin Min Zhang Junye Lu Jinbo Ma Youping He Yuangen Yao | 2014 | High Power Laser Science and Engineering2014，2，1： | 3 |
| 9 | The mechanosensitive lncRNA Neat1 promotes osteoblast function through paraspeckle-dependent Smurf1 mRNA retention显示文摘Mechanical stimulation plays an important role in bone remodeling. Exercise-induced mechanical loading enhances bone strength,whereas mechanical unloading leads to bone loss. Increasing evidence has demonstrated that long noncoding RNAs(lnc RNAs) play key roles in diverse biological, physiological and pathological contexts. However, the roles of lnc RNAs in mechanotransduction and their relationships with bone formation remain unknown. In this study, we screened mechanosensing lnc RNAs in osteoblasts and identified Neat1, the most clearly decreased lnc RNA under simulated microgravity. Of note, not only Neat1 expression but also the specific paraspeckle structure formed by Neat1 was sensitive to different mechanical stimulations, which were closely associated with osteoblast function. Paraspeckles exhibited small punctate aggregates under simulated microgravity and elongated prolate or larger irregular structures under mechanical loading. Neat1 knockout mice displayed disrupted bone formation, impaired bone structure and strength, and reduced bone mass. Neat1 deficiency in osteoblasts reduced the response of osteoblasts to mechanical stimulation. In vivo, Neat1 knockout in mice weakened the bone phenotypes in response to mechanical loading and hindlimb unloading stimulation. Mechanistically, paraspeckles promoted nuclear retention of E3 ubiquitin ligase Smurf1 m RNA and downregulation of their translation, thus inhibiting ubiquitination-mediated degradation of the osteoblast master transcription factor Runx2, a Smurf1 target. Our study revealed that Neat1 plays an essential role in osteoblast function under mechanical stimulation, which provides a paradigm for the function of the lnc RNA-assembled structure in response to mechanical stimulation and offers a therapeutic strategy for long-term spaceflight-or bedrest-induced bone loss and age-related osteoporosis. | Caizhi Liu Xingcheng Gao Yuheng Li Weijia Sun Youjia Xu Yingjun Tan Ruikai Du Guohui Zhong Dingsheng Zhao Zizhong Liu Xiaoyan Jin Yinlong Zhao Yinbo Wang Xinxin Yuan Junjie Pan Guodong Yuan Youyou Li Wenjuan Xing Guanghan Kan Yanqing Wang Qi Li Xuan Han Jianwei Li Shukuan Ling Yingxian Li | 2022 | Bone Research2022，10，2： | 3 |

| 11 | 磁共振动态增强乳腺扫描及时间信号曲线结合在早期乳腺癌诊断中的应用价值(英文)显示文摘Objective: The aim of this study was to investigate the application value of breast dynamic contrast-enhanced magnetic resonance imaging combined with time signal curve in diagnosis of early breast cancer. Methods: Conducted dynamic contrast-enhanced MRI and drew the time signal curves of breast lesions in 60 patients with breast disease (malignant 46, benign 14). Results: Morphological features of malignant tumors mostly showed blurred or thin spiculate outlines, irregular shape or lobular signs, signal heterogeneity or peripheral enhancement in dynamic contrast-enhanced MRI. Time signal curve showed type Ⅲ or Ⅱ. Morphologic features of benign tumors mostly showed clear edge, regular shape and homogeneous signal, or diffuse spot enhancement. Time signal curve showed type Ⅰ or Ⅱ. Conclusion: breast dynamic contrast enhanced scan in MRI can provide morphology and functional diagnosis information of the breast tissues. Dynamic contrast-enhanced MRI combined with time signal curve can further improve the accuracy of diagnosis of early breast cancer. | Yakun He Guohui Xu Jing Ren Min Wang Jin Liu | 2013 | The Chinese-German Journal of Clinical Oncology2013，12，2： | 2 |
| 12 | Single-cell RNA sequencing reveals B cell-T cell interactions in vascular adventitia of hyperhomocysteinemia-accelerated atherosclerosis显示文摘Dear Editor Cardiovascular disease(CVD)is the leading cause of death around the world(Truelsen,et al.,2015).Atherosclerosis,the dominant underlying cause of CVD,is a chronic inflam-matory disease characterized by lipid accumulation and immune cell infiltration in plaques and vessels(Weber,et al.,1950).The immune microenvironment is critical for the development of atherosclerosis.Homocysteine(Hcy)is an intermediate product of methionine metabolism,and its ele-vation in plasma(>15μmol/L),known as hyperhomocys-teinemia(HHcy),is an independent risk factor for atherosclerosis.HHcy is more common in Asia because of genetic factors and dietary habits(Huo,et al.,2015).folic acid supplement is one of the most important way to treat HHcy in clinic.Although HHcy potentiates atherosclerosis mainly through endothelial injury and inflammatory activa-tion(Luo,et al.,2016),a comprehensive understanding of the immune microenvironment and potential mechanisms in HHcy-accelerated atherosclerotic aortas(HHcy-AA)is still lacking. | Xiaolong Ma Jiacheng Deng Lulu Han Yuwei Song Yutong Miao Xing Du Guohui Dang Dongmin Yang Bitao Zhong Changtao Jiang Wei Kong Qingbo Xu Juan Feng Xian Wang | 2022 | Protein & Cell2022，13，7： | 2 |

| 14 | Use of angiotensin-converting enzyme inhibitors and angiotensin Ⅱ receptor blockers in context of COVID-19 outbreak:a retrospective analysis显示文摘The possible effects of angiotensin-converting enzyme inhibitors(ACEIs)or angiotensin Ⅱ receptor blockers(ARBs)on COVID-19 disease severity have generated considerable debate.We performed a single-center,retrospective analysis of hospitalized adult COVID-19 patients in Wuhan,China,who had definite clinical outcome(dead or discharged)by February 15,2020.Patients on anti-hypertensive treatment with or without ACEI/ARB were compared on their clinical characteristics and outcomes.The medical records from 702 patients were screened.Among the 101 patients with a history of hypertension and taking at least one anti-hypertensive medication,40 patients were receiving ACEI/ARB as part of their regimen,and 61 patients were on antihypertensive medication other than ACEI/ARB.We observed no statistically significant differences in percentages of in-hospital mortality(28%vs.34%,P=0.46),ICU admission(20%vs.28%,P=0.37)or invasive mechanical ventilation(18%vs.26%,P=0.31)between patients with or without ACEI/ARB treatment.Further multivariable adjustment of age and gender did not provide evidence for a significant association between ACEI/ARB treatment and severe COVID-19 outcomes.Our findings confirm the lack of an association between chronic receipt of reninangiotensin system antagonists and severe outcomes of COVID-19.Patients should continue previous antihypertensive therapy until further evidence is available. | Jiuyang Xu Chaolin Huang Guohui Fan Zhibo Liu Lianhan Shang Fei Zhou Yeming Wang Jiapei Yu Luning Yang Ke Xie Zhisheng Huang Lixue Huang Xiaoying Gu Hui Li Yi Zhang Yimin Wang Frederick G.Hayden Peter W.Horby Bin Cao Chen Wang | 2020 | Frontiers of Medicine2020，14，5： | 2 |
| 15 | Light-Responsive Nanomaterials for Cancer Therapy显示文摘Due to its unique advantages,which include minimal invasiveness and relative clinical safety,photother-apy is considered to be a promising approach for cancer treatment.However,the treatment efficacy of phototherapy is often restricted by the limited depth of light penetration and the low targeting effect of phototherapeutic agents.The emergence of light-responsive nanomaterials offers a possible approach to achieve enhanced phototherapy potency.This review summarizes the progress in biomedical applica-tions of light-responsive nanomaterials for cancer therapy,which include photothermal therapy(PTT),photodynamic therapy(PDT),light-responsive molecule delivery,and light-controlled combination ther-apy.Future prospects are also discussed.This review aims to demonstrate the significance of light-responsive nanomaterials in cancer therapy and to provide strategies to expand the applications of phototherapy. | Xu Zhang Sheng Wang Guohui Cheng Peng Yu Jin Chang | 2022 | Engineering2022，8，6： | 1 |
| 16 | CTCs Detection and Whole-exome Sequencing Might Be Used to Differentiate Benign and Malignant Pulmonary Nodules显示文摘Background and objective Low-density computed tomography(LDCT)improved early lung cancer diagnosis but introduces an excess of false-positive pulmonary nodules data.Hence,accurate diagnosis of early-stage lung cancer remains challenging.The purpose of the study was to assess the feasibility of using circulating tumour cells(CTCs)to differentiate malignant from benign pulmonary nodules.Materials and methods 122 patients with suspected malignant pulmonary nodules detected on chest CT in preparation for surgery were prospectively recruited.Peripheral blood samples were collected before surgery,and CTCs were identified upon isolation by size of epithelial tumour cells and morphological analysis.Laser capture microdissection,MALBAC amplification,and whole-exome sequencing were performed on 8 samples.The diagnostic efficacy of CTCs counting,and the genomic variation profile of benign and malignant CTCs samples were analysed.Results Using 2.5 cells/5 m L as the cut-off value,the area under the receiver operating characteristic curve was of 0.651(95%confidence interval:0.538-0.764),with a sensitivity and specificity of 0.526 and 0.800,respectively,and positive and negative predictive values of 91.1%and 30.3%,respectively.Distinct sequence variations differences in DNA damage repair-related and driver genes were observed in benign and malignant samples.TP53 mutations were identified in CTCs of four malignant cases;in particular,g.7578115T>C,g.7578645C>T,and g.7579472G>C were exclusively detected in all four malignant samples.Conclusion CTCs play an ancillary role in the diagnosis of pulmonary nodules.TP53 mutations in CTCs might be used to identify benign and malignant pulmonary nodules. | Changdan XU Xiaohong XU Weipeng SHAO Hongliang SUN Xiaohong LIU Hongxiang FENG Xianbo ZUO Jingyang GAO Guohui WANG Xiongtao YANG Runchuan GU Shutong GE Shijie WANG Liwei GAO Guangying ZHU | 2023 | 中国肺癌杂志2023，26，6： | 1 |

| 18 | Tuning the crystallite size of monoclinic ZrO_(2) to reveal critical roles of surface defects on m–ZrO_(2) catalyst for direct synthesis of isobutene from syngas显示文摘The effects of crystallite size on the physicochemical properties and surface defects of pure monoclinic ZrO_(2) catalysts for isobutene synthesis were studied.We prepared a series of monoclinic ZrO_(2) catalysts with different crystallite size by changing calcination temperature and evaluated their catalytic performance for isobutene synthesis from syngas.ZrO_(2) with small crystalline size showed higher CO conversion and isobutene selectivity,while samples with large crystalline size preferred to form dimethyl ether(DME)instead of hydrocarbons,much less to isobutene.Oxygen defects(ODefects)analyzed by X-ray photoelectron spectroscopy(XPS)provided evidence that more ODefectsoccupied on the surface of ZrO_(2) catalysts with smaller crystalline size.Electron paramagnetic resonance(EPR)and ultraviolet–visible diffuse reflectance(UV–vis DRS)confirmed the presence of high concentration of surface defects and Zr3+on mZrO_(2)-5.9 sample,respectively.In situ diffuse reflectance infrared Fourier transform spectroscopy(in situ DRIFTS)analysis indicated that the adsorption strength of formed formate species on catalyst reduced as the crystalline size decreased.These results suggested that surface defects were responsible for CO activation and further influenced the adsorption strength of surface species,and thus the products distribution changed.This study provides an in-depth insight for active sites regulation of ZrO_(2) catalyst in CO hydrogenation reaction. | Xuemei Wu Minghui Tan Bing Xu Shengying Zhao Qingxiang Ma Yingluo He Chunyang Zeng Guohui Yang Noritatsu Tsubaki Yisheng Tan | 2021 | Chinese Journal of Chemical Engineering2021，34，7： | 1 |
