1OsWRKY03, a rice transcriptional activator that functions in defense signaling pathway upstream of OsNPR1显示文摘WRKY family proteins are a class of plant specific transcription factors that involve in many stress response pathways. It has been shown that one Arabidopsis WRKY protein, AtWRKY29/22, is activated by MAP kinase signaling cascade and confers resistance to both bacterial and fungal pathogens. However, little is known about the biological roles of WRKY proteins in rice. In this study, we investigated the expression patterns of rice AtWRKY29/22 homolog, OsWRKY03, under different conditions, and also its possible role involved in plant defense. Our results showed that OsWRKY03 was up-regulated by several defense signaling molecules or different treatments. Further analysis revealed that the expres- sion of OsWRKY03 was light dependent. Transcriptional activation activity of OsWRKY03 was also demonstrated by yeast functional assay. Transient expression of OsWRKY03-GFP fusion protein in onion epidermis cells showed that OsWRKY03 was a nuclear localized protein. OsNPR1 as well as several other pathogenesis-related genes, such as OsPR1b, phenylalanine ammonia-lyase (ZB8) and peroxidase (POX22.3), were induced in OsWRKY03-overexpressing transgenic plants. These results indicated that OsWRKY03 is located upstream of OsNPR1 as a transcriptional activator in salicylic acid (SA)-dependent or jasmonic acid (JA)-dependent defense signaling cascades.Xiao Qiang LIU Xian Quan BAI Qian QIAN Xiu Jie WANG Ming Sheng CHEN Cheng Cai CHU 2005Cell Research2005,15,8:55
2Methanation of carbon dioxide on Ni/ZrO_2-Al_2O_3 catalysts:Effects of ZrO_2 promoter and preparation method of novel ZrO_2-Al_2O_3 carrier显示文摘The novel nickel-based catalysts with a nickel content of 12 wt% were prepared with the zirconia-alumina composite as the supports. The new carriers, ZrO2 improved alumina, were synthesized by three methods, i.e., impregnation-precipitation, co-precipitation, and impregnation method. The catalytic properties of these catalysts were investigated in the methanation of carbon dioxide, and the samples were characterized by X-ray diffraction (XRD), X-ray photoelectron spectroscope (XPS), temperature-programmed reduction (TPR) and temperature-programmed desorption (TPD) techniques. The new catalysts showed higher catalytic activity and better stability than Ni/γ-Al2O3. Furthermore, as a support for new nickel catalyst, the ZrO2-Al2O3 composite prepared by the impregnation-precipitation method was more efficient than the other supports in the methanation of carbon dioxide. The highly dispersed zirconium oxide on the surface of γ-Al2O3 inhibited the formation of nickel aluminate-like phase, which was responsible for the better dispersion of Ni species and easier reduction of NiO species, leading to the enhanced catalytic performance of corresponding catalyst.Mengdie Cai Jie Wen Wei Chu Xueqing Cheng Zejun Li 2011Journal of Natural Gas Chemistry2011,20,3:33
3Clinical and Laboratory Findings of Nonacute Neurobrucellosis显示文摘INTRODUCTION Brucellosis is the most common zoonotic infection in the world.It is an endemic disease in many areas throughout the world.Human brucellosis is a multisystem disease that may present with a broad spectrum of clinical manifestations.The central nervous system (CNS) involvement is a rare but serious neurological complication of brucellosis.Neurobrucellosis (NB) often is underdiagnosed,which is partly because of unawareness about the disease among the treating physicians.Clinically nonacute NB is more common than acute NB.Therefore,in order to better understand the nonacute NB,we summarized 14 cases,aimed to shed light to detailed neurologic features of nonacute NB,as well as their laboratory findings.Li-Dong Jiao Chang-Biao Chu Chhetri Jagadish Kumar Jie Cui Xian-Ling Wang Li-Yong Wu Cun-Jiang Li Xiang-Bo Wang 2015Chinese Medical Journal2015,,13:24

5Cancer incidence and mortality in Shandong province,2012显示文摘Objective: Population-based cancer registration data in 2012 from all available cancer registries in Shandong province were collected by Shandong Center for Disease Control and Prevention(SDCDC). SDCDC estimated the numbers of new cancer cases and cancer deaths in Shandong province with compiled cancer incidence and mortality rates.Methods: In 2015, there were 21 cancer registries submitted data of cancer incidence and deaths occurred in 2012. All the data were checked and evaluated based on the National Central Cancer Registry(NCCR) criteria of data quality. Qualified data from 15 registries were used for cancer statistics analysis as provincial estimation. The pooled data were stratified by area(urban/rural), gender, age group(0, 1-4, 5-9, 10-14, …, 85+ years) and cancer type. New cancer cases and deaths were estimated using age-specific rates and corresponding provincial population in 2012. The Chinese census data in 2000 and Segi's population were applied for age-standardized rates. All the rates were expressed per 100,000 person-year.Results: Qualified 15 cancer registries(4 urban and 11 rural registries) covered 17,189,988 populations(7,486,039 in urban and 9,703,949 in rural areas). The percentage of cases morphologically verified(MV%) and death certificate-only cases(DCO%) were 66.12% and 2.93%, respectively, and the mortality to incidence rate ratio(M/I) was 0.60. A total of 253,060 new cancer cases and 157,750 cancer deaths were estimated in Shandong province in 2012. The incidence rate was 263.86/100,000(303.29/100,000 in males, 223.23/100,000 in females), the age-standardized incidence rates by Chinese standard population(ASIRC) and by world standard population(ASIRW) were 192.42/100,000 and 189.50/100,000 with the cumulative incidence rate(0-74 years old) of 22.07%. The cancer incidence, ASIRC and ASIRW in urban areas were 267.64/100,000, 195.27/100,000 and 192.02/100,000 compared to 262.32/100,000, 191.26/100,000 and 188.48/100,000 in rural areas, respectively. The cancer mortality was 164.47/100,000(207.42/100,000 in males, 120.23/100,000 in females), the age-standardized incidence rates by Chinese standard population(ASMRC) and by world standard population(ASMRW) were 117.54/100,000 and 116.90/100,000, and the cumulative mortality rate(0-74 years old) was 13.53%. The cancer mortality, ASMRC and ASMRW were 141.59/100,000, 101.17/100,000 and 100.33/100,000 in urban areas, and 173.79/100,000, 124.20/100,000 and 123.64/100,000 in rural areas, respectively. Cancers of the lung, stomach, liver, esophagus, colorectum, female breast, brain, leukemia, bladder and pancreas were the most common cancers, accounting for about 82.12% of all cancer new cases. Lung cancer, stomach cancer, liver cancer, esophageal cancer, colorectal cancer, female breast cancer, pancreatic cancer, brain tumor, leukemia and lymphoma were the leading causes of cancer death, accounting for about 89.01% of all cancer deaths. The cancer spectrum showed difference between urban and rural, males and females both in incidence and mortality rates.Conclusions: Cancer surveillance information in Shandong province is making great progress with the increasing number of cancer registries, population coverage and the improving data quality. Cancer registration plays a fundamental role in cancer control by providing basic information on population-based cancer incidence, mortality, survival and time trend. The disease burden of cancer is serious in Shandong province, and so cancer prevention and control in Shandong province should be enhanced including health education, health promotion, cancer screening and cancer care services.Zhentao Fu Zilong Lu Yingmei Li jiyu Zhang Gaohui Zhang Xianxian Chen Jie Chu Jie Ren Haiyan Liu Xiaolei Guo 2016Chinese Journal of Cancer Research2016,28,3:17
6A hybrid invisibility cloak based on integration of transparent metasurfaces and zero-index materials显示文摘The invisibility cloak,a long-standing fantastic dream for humans,has become more tangible with the development of metamaterials.Recently,metasurface-based invisibility cloaks have been proposed and realized with significantly reduced thickness and complexity of the cloaking shell.However,the previous scheme is based on reflection-type metasurfaces and is thus limited to reflection geometry.In this work,by integrating the wavefront tailoring functionality of transparent metasurfaces and the wave tunneling functionality of zero-index materials,we have realized a unique type of hybrid invisibility cloak that functions in transmission geometry.The principle is general and applicable to arbitrary shapes.For experimental demonstration,we constructed a rhombic double-layer cloaking shell composed of a highly transparent metasurface and a double-zero medium consisting of dielectric photonic crystals with Dirac cone dispersions.The cloaking effect is verified by both full-wave simulations and microwave experimental results.The principle also reveals exciting possibilities for realizing skin-thick ultrathin cloaking shells in transmission geometry,which can eliminate the need for spatially varying extreme parameters.Our work paves a path for novel optical and electromagnetic devices based on the integration of metasurfaces and metamaterials.Hongchen Chu Qi Li Bingbing Liu Jie Luo Shulin Sun Zhi Hong Hang Lei Zhou Yun Lai 2018Light(Science & Applications)2018,7,1:13
7Damage identification method of girder bridges based on finite element model updating and modal strain energy显示文摘A timely and accurate damage identification for bridge structures is essential to prevent sudden failures/collapses and other catastrophic accidents.Based on response surface model(RSM)updating and element modal strain energy(EMSE)damage index,this paper proposes a novel damage identification method for girder bridge structures.The effectiveness of the proposed damage identification method is investigated using experiments on four simply supported steel beams.With Xiabaishi Bridge,a prestressed continuous rigid frame bridge with large span,as the engineering background,the proposed damage identification method is validated by using numerical simulation to generate different bearing damage scenarios.Finally,the efficiency of the method is justified by considering its application to identifying cracking damage for a real continuous beam bridge called Xinyihe Bridge.It is concluded that the EMSE damage index is sensitive to the cracking damage and the bearing damage.The locations and levels of multiple cracking damages and bearing damages can be also identified.The results illuminate a great potential of the proposed method in identifying damages of real bridge structures.NIU Jie ZONG Zhou Hong CHU Fu Peng 2015Science China(Technological Sciences)2015,58,4:12
8Rice functional genomics:decades'efforts and roads ahead显示文摘Rice(Oryza sativa L.)is one of the most important crops in the world.Since the completion of rice reference genome sequences,tremendous progress has been achieved in understanding the molecular mechanisms on various rice traits and dissecting the underlying regulatory networks.In this review,we summarize the research progress of rice biology over past decades,including omics,genome-wide association study,phytohormone action,nutrient use,biotic and abiotic responses,photoperiodic flowering,and reproductive development(fertility and sterility).For the roads ahead,cutting-edge technologies such as new genomics methods,high-throughput phenotyping platforms,precise genome-editing tools,environmental microbiome optimization,and synthetic methods will further extend our understanding of unsolved molecular biology questions in rice,and facilitate integrations of the knowledge for agricultural applications.Rongzhi Chen Yiwen Deng Yanglin Ding Jingxin Guo Jie Qiu Bing Wang Changsheng Wang Yongyao Xie Zhihua Zhang Jiaxin Chen Letian Chen Chengcai Chu Guangcun He Zuhua He Xuehui Huang Yongzhong Xing Shuhua Yang Daoxin Xie Yaoguang Liu Jiayang Li 2022Science China(Life Sciences)2022,65,1:12
9Two-dimensional heterostructure promoted infrared photodetection devices显示文摘It is a rapidly developed subject in expanding the fundamental properties and application of two-dimensional(2D)materials.The weak van der Waals interaction in 2D materials inspired researchers to explore 2D heterostructures(2DHs)based broadband photodetectors in the far-infrared(IR)and middle-IR regions with high response and high detectivity.This review focuses on the strategy and motivation of designing 2DHs based high-performance IR photodetectors,which provides a wide view of this field and new expectation for advanced photodetectors.First,the photocarriers'generation mechanism and frequently employed device structures are presented.Then,the 2DHs are divided into semimetal/semiconductor 2DHs,semiconductor/semiconductor 2DHs,and multidimensional semi-2DHs;the advantages,motivation,mechanism,recent progress,and outlook are discussed.Finally,the challenges for next-generation photodetectors are described for this rapidly developing field.Gaofeng Rao Xuepeng Wang Yang Wang Peihua Wangyang Chaoyi Yan Junwei Chu Lanxin Xue Chuanhui Gong Jianwen Huang Jie Xiong Yanrong Li 2019InfoMat2019,1,3:12
10A Five-year Surveillance of Carbapenemase-producing Klebsiella pneumoniae in a Pediatric Hospital in China Reveals Increased Predominance of NDM-1显示文摘Objective To characterize carbapenem(CPM)-non-susceptible Klebsiel a pneumoniae(K. pneumoniae) and carbape-nemase produced by these strains isolated from Beijing Children's Hospital based on a five-year surveillance. Methods The Minimal Inhibition Concentration values for 15 antibiotics were assessed using the Phonix100 compact system. PCR amplification and DNA sequencing were used to detect genes encoding carbapenemases. WHONET 5.6 was finally used for resistance analysis. Results In total, 179 strains of CPM-non-susceptible K. pneumoniae were isolated from January, 2010 to December, 2014. The rates of non-susceptible to imipenem and meropenem were 95.0% and 95.6%, respectively. In the 179 strains, 95(53.1%) strains carried the blaIMP gene, and IMP-4 and IMP-8 were detected in 92(96.8%) and 3(3.2%) IMP-producing isolates, respectively. 65(36.3%) strains carried the blaNDM-1 gene. 6(3.4%) strains carried the blaKPC gene, and KPC-2 were detected in 6 KPC-producing isolates. In addition, New Delhi-Metallo-1(NDM-1) producing isolates increased from 7.1% to 63.0% in five years and IMP-4 producing isolates decreased from 75.0% to 28.3%. Conclusion High frequencies of multiple resistances to antibiotics were observed in the CPM-non-susceptible K. pneumoniae strains isolated from Beijing Children's Hospital. The production of IMP-4 and NDM-1 metallo-β-lactamases appears to be an important mechanism for CPM-nonsusceptible in K. pneumoniae.DONG Fang LU Jie WANG Yan SHI Jin ZHEN Jing Hui CHU Ping ZHEN Yang HAN Shu Jing GUO Yong Li SONG Wen Qi 2017Biomedical and Environmental Sciences2017,30,8:10
11Oncogenic AURKA-enhanced N6-methyladenosine modification increases DROSHA mRNA stability to transactivate STC1 in breast cancer stem-like cells显示文摘RNase III DROSHA is upregulated in multiple cancers and contributes to tumor progression by hitherto unclear mechanisms.Here,we demonstrate that DROSHA interacts withβ-Catenin to transactivate STC1 in an RNA cleavage-independent manner,contributing to breast cancer stem-like cell(BCSC)properties.DROSHA mRNA stability is enhanced by N6-methyladenosine(m^(6)A)modification which is activated by AURKA in BCSCs.AURKA stabilizes METTL14 by inhibiting its ubiquitylation and degradation to promote DROSHA mRNA methylation.Moreover,binding of AURKA to DROSHA transcript further strengthens the binding of the m^(6)A reader IGF2BP2 to stabilize m^(6)A-modified DROSHA.In addition,wild-type DROSHA,but not an m^(6)A methylation-deficient mutant,enhances BCSC stemness maintenance,while inhibition of DROSHA m^(6)A modification attenuates BCSC traits.Our study unveils the AURKA-induced oncogenic m^(6)A modification as a key regulator of DROSHA in breast cancer and identifies a novel DROSHA transcriptional function in promoting the BCSC phenotype.Fei Peng Jie Xu Bai Cui Qilan Liang Sai Zeng Bin He Hong Zou Manman Li Huan Zhao Yuting Meng Jin Chen Bing Liu Shasha Lv Peng Chu Fan An Zifeng Wang Junxiu Huang Yajing Zhan Yuwei Liao Jinxin Lu Lingzhi Xu Jin Zhang Zhaolin Su Zhiguang Li Fangjun Wang Eric W-FLam Quentin Liu 2021Cell Research2021,31,3:9

14The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST)显示文摘The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST, also called the Guo Shou Jing Telescope) is a special reflecting Schmidt telescope. LAMOST's special design allows both a large aperture (effective aperture of 3.6 m-4.9 m) and a wide field of view (FOV) (5°). It has an innovative active reflecting Schmidt configuration which continuously changes the mirror's surface that adjusts during the observation process and combines thin deformable mirror active optics with segmented active optics. Its primary mirror (6.67m×6.05 m) and active Schmidt mirror (5.74m×4.40 m) are both segmented, and composed of 37 and 24 hexagonal sub-mirrors respectively. By using a parallel controllable fiber positioning technique, the focal surface of 1.75 m in diameter can accommodate 4000 optical fibers. Also, LAMOST has 16 spectrographs with 32 CCD cameras. LAMOST will be the telescope with the highest rate of spectral acquisition. As a national large scientific project, the LAMOST project was formally proposed in 1996, and approved by the Chinese government in 1997. The construction started in 2001, was completed in 2008 and passed the official acceptance in June 2009. The LAMOST pilot survey was started in October 2011 and the spectroscopic survey will launch in September 2012. Up to now, LAMOST has released more than 480 000 spectra of objects. LAMOST will make an important contribution to the study of the large-scale structure of the Universe, structure and evolution of the Galaxy, and cross-identification of multiwaveband properties in celestial objects.Xiang-Qun Cui Yong-Heng Zhao Yao-Quan Chu Guo-Ping Li Qi Li Li-Ping Zhang Hong-Jun Su Zheng-Qiu Yao Ya-Nan Wang Xiao-Zheng Xing Xin-Nan Li Yong-Tian Zhu Gang Wang Bo-Zhong Gu A-Li Luo Xin-Qi Xu Zhen-Chao Zhang Gen-Rong Liu Hao-Tong Zhang De-Hua Yang Shu-Yun Cao Hai-Yuan Chen Jian-Jun Chen Kun-Xin Chen Ying Chen Jia-Ru Chu Lei Feng Xue-Fei Gong Yong-Hui Hou Hong-Zhuan Hu Ning-Sheng Hu Zhong-Wen Hu Lei Jia Fang-Hua Jiang Xiang Jiang Zi-Bo Jiang Ge Jin Ai-Hua Li Yan Li Ye-Ping Li Guan-QunLiu Zhi-Gang Liu Huo-Ming Shi Zheng-Hong Tang Qing-Sheng Tao Xiang-Yan Yuan Chao Zhai Jing Zhang Yan-Xia Zhang Yong Zhang Ming Zhao Fang Zhou Guo-Hua Zhou Jie Zhu Si-Cheng Zou 2012Research in Astronomy and Astrophysics2012,12,9:8
15Optimal incision sites to reduce corneal aberration variations after small incision phacoemulsification cataract surgery显示文摘AIM: To analyze the effect of steep meridian small incision phacoemulsification cataract surgery on anterior,posterior and total corneal wavefront aberration.· METHODS: Steep meridian small incision phacoemulsification cataract surgery was performed in age-related cataract patients which were divided into three groups according to the incision site: 12 o'clock, 9o'clock and between 9 and 12 o'clock(BENT) incision groups. The preoperative and 3-month postoperative root mean square(RMS) values of anterior, posterior and total corneal wavefront aberration including coma,spherical aberration, and total higher-order aberrations(HOAs), were measured by Pentacam scheimpflug imaging. The mean preoperative and postoperative corneal wavefront aberrations were documented.·RESULTS: Total corneal aberration and total lower-order aberrations decreased significantly in three groups after operation. RMS value of total HOAs decreased significantly postoperatively in the 12 o'clock incision group(P <0.001). Corneal spherical aberration was statistically significantly lower after steep meridian small incision phacoemulsification cataract surgery in BENT incision group(P <0.05) and Pearson correlation analysisindicated that spherical aberration changes had no significant relationship with total astigmatism changes in all three corneal incision location.·CONCLUSION: Corneal incision of phacoemulsification cataract surgery can affect corneal wavefront aberration.The 12 o'clock corneal incision eliminated more HOAs and the spherical aberrations decreased in BENT incision group obviously when we selected steep meridian small incision. Cataract lens replacement using wavefront-corrected intraocular lens combined with optimized corneal incision site would improve ocular aberration results.Ling Chu Jiang-Yue Zhao Jin-Song Zhang Jie Meng Ming-Wu Wang Ya-Jing Yang Jia-Ming Yu 2016International Journal of Ophthalmology(English edition)2016,9,4:8
16A cyclodextrin-based nanoformulation achieves co-delivery of ginsenoside Rg3 and quercetin for chemo-immunotherapy in colorectal cancer显示文摘The immune checkpoint blockade therapy has profoundly revolutionized the field of cancer immunotherapy. However, despite great promise for a variety of cancers, the efficacy of immune checkpoint inhibitors is still low in colorectal cancer(CRC). This is mainly due to the immunosuppressive feature of the tumor microenvironment(TME). Emerging evidence reveals that certain chemotherapeutic drugs induce immunogenic cell death(ICD), demonstrating great potential for remodeling the immunosuppressive TME. In this study, the potential of ginsenoside Rg3(Rg3) as an ICD inducer against CRC cells was confirmed using in vitro and in vivo experimental approaches. The ICD efficacy of Rg3 could be significantly enhanced by quercetin(QTN) that elicited reactive oxygen species(ROS). To amelioratein vivo delivery barriers associated with chemotherapeutic drugs, a folate(FA)-targeted polyethylene glycol(PEG)-modified amphiphilic cyclodextrin nanoparticle(NP) was developed for co-encapsulation of Rg3 and QTN. The resultant nanoformulation(CD-PEG-FA.Rg3.QTN) significantly prolonged blood circulation and enhanced tumor targeting in an orthotopic CRC mouse model, resulting in the conversion of immunosuppressive TME. Furthermore, the CD-PEG-FA.Rg3.QTN achieved significantly longer survival of animals in combination with Anti-PD-L1.

17Cholesterol transport through the peroxisome-ER membrane contacts tethered by PI(4,5)P2 and extended synaptotagmins显示文摘Most mammalian cells take up cholesterol from low-density lipoproteins(LDLs) via receptor-mediated endocytosis.After reaching lysosomes,LDL-derived cholesterol continues to transport to downstream organelles including the ER for specific structural and functional needs.Peroxisomes are recently found to receive cholesterol from lysosomes through lysosomeperoxisome membrane contacts.However,whether and how cholesterol is conveyed from peroxisomes to the ER remain unknown.Here,by combining high-resolution microscopic analyses and in vitro reconstitution of highly purified organelles or artificial liposomes,we demonstrate that peroxisomes form membrane contacts with the ER through the interaction between peroxisomal PI(4,5)P2 and ER-resident extended synaptotagmin-1,2 and 3(E-Syts).Depletion of peroxisomal PI(4,5)P2 or ESyts markedly decreases peroxisome-ER membrane contacts and induces cholesterol accumulation in lysosomes.Furthermore,we show that cholesterol is delivered from 3H-labeled peroxisomes or PI(4,5)P2-containing liposomes to the ER in vitro,and that the presence of peroxisomes augments cholesterol transfer from lysosomes to the ER.Together,our study reveals a new cholesterol transport pathway along the lysosome-peroxisome-ER membrane contacts in the cell.Jian Xiao Jie Luo Ao Hu Ting Xiao Meixin Li Zekai Kong Luyi Jiang Zimu Zhou Yacheng Liao Chang Xie Beibei Chu Honghua Miao Boliang Li Xiongjie Shi Bao-Liang Song 2019Science China(Life Sciences)2019,62,9:8

19Body mass index does not affect the survival of pancreatic cancer patients显示文摘AIM to evaluate the association of body mass index(b MI) with the overall survival of pancreatic ductal adenocarcinoma(PDAC) patients.METHODS A retrospective analysis of PDAC patients diagnosed in the National Cancer Center of China between January 1999 and December 2014 was performed. these patients were categorized into four b MI groups(< 18.5, 18.5-22.9, 23-27.4 and ≥ 27.5 kg/m2). χ2 tests for comparison of the proportions of categorical variables, and Student's t-test or Mann-Whitney test for continuous variables were employed. Survival analysis was performed with the Kaplan-Meyer method. their HRs of mortality and 95%CIs were estimated using the Cox proportional hazards model.RESULTS With a median age of 59.6 years(range: 22.5-84.6 years), in total 1783 PDAC patients were enrolled in this study. their mean usual b MI was 24.19 ± 3.53 for the whole cohort. More than half of the patients(59.3%) experienced weight loss during the disease onset and progression. Compared with healthy-weight individuals, newly diagnosed patients who were overweight or obese had more severe weight loss during their disease onset and progression(P < 0.001). Individuals who were overweight or obese were associated with positive smoking history(P < 0.001). A significant difference in comorbidity of diabetes(P = 0.044) and coronary artery disease(P < 0.001) was identified between high b MI and normal-weight patients. After a median follow-up of 8 mo, the survival analysis showed no association between b MI and the overall survival(P = 0.90, n = 1783). When we stratified the whole cohort by pancreatic cancer stage, no statistically significant association between b MI and overall survival was found for resectable(P = 0.99, n = 217), unresectable locally advanced(P = 0.90, n = 316) and metastatic patients(P = 0.88, n = 1250), respectively. the results did not change when we used the b MI at diagnosis.CONCLUSION Our results showed no significance of b MI for the overall survival of PDAC patients.Qing-long Jiang Cheng-feng Wang Yan-tao tian Huang Huang Shui-Sheng Zhang Dong-bing Zhao Jie Ma Wei Yuan Yue-Min Sun Xu Che Jian-Wei Zhang Yun-Mian Chu Ya-Wei Zhang Ying-tai Chen 2017World Journal of Gastroenterology2017,23,34:7
20Molecular Characterization and Correlation with β-lactam Resistance of Streptococcus pneumonia Isolates in Hangzhou,China显示文摘Penicillin-binding proteins(PBPs) are the target of β-lactam antibiotics(the major treatment for Streptococcus pneumoniae infections),and mutations in PBPs are considered as a primary mechanism for the development of β-lactam resistance in S.pneumoniae.This study was conducted to investigate the mutations in the PBPs of clinical S.pneumoniae isolates in Hangzhou,China,in correlation with β-lactam resistance.Results showed that 19 F was the predominant serotype(7/27) and 14 of the S.pneumoniae isolates were resistant to both penicillin G and cephalosporin.Genotyping results suggested that β-lactam-resistant isolates primarily exhibited single-site mutations in both the STMK and SRNVP motifs of pbp1 a in combination with double-site mutations in the STMK motif of pbp2 x,which might be the primary mechanisms underlying the β-lactam resistance of the isolates in this study.chu mei fen liu xiao xiang zhang shao ni huang yan ying du peng wang li fang ji lei yan jie sun ai hua 2018Biomedical and Environmental Sciences2018,31,5:7
