1The Chinese Society of Clinical Oncology(CSCO):clinical guidelines for the diagnosis and treatment of gastric cancer显示文摘China is one of the countries with the highest incidence of gastric cancer.There are differences in epidemiological characteristics,clinicopathological features,tumor biological characteristics,treatment patterns,and drug selection between gastric cancer patients from the Eastern and Western countries.Non-Chinese guidelines cannot specifically reflect the diagnosis and treatment characteristics for the Chinese gastric cancer patients.The Chinese Society of Clinical Oncology(CSCO)arranged for a panel of senior experts specializing in all sub-specialties of gastric cancer to compile,discuss,and revise the guidelines on the diagnosis and treatment of gastric cancer based on the findings of evidence-based medicine in China and abroad.By referring to the opinions of industry experts,taking into account of regional differences,giving full consideration to the accessibility of diagnosis and treatment resources,these experts have conducted experts’consensus judgement on relevant evidence and made various grades of recommendations for the clinical diagnosis and treatment of gastric cancer to reflect the value of cancer treatment and meeting health economic indexes.This guideline uses tables and is complemented by explanatory and descriptive notes covering the diagnosis,comprehensive treatment,and follow-up visits for gastric cancer.Feng-Hua Wang Lin Shen Jin Li Zhi-Wei Zhou Han Liang Xiao-Tian Zhang Lei Tang Yan Xin Jing Jin Yu-Jing Zhang Xiang-Lin Yuan Tian-Shu Liu Guo-Xin Li Qi Wu Hui-Mian Xu Jia-Fu Ji Yuan-Fang Li Xin Wang Shan Yu Hao Liu Wen-Long Guan Rui-Hua Xu 2019Cancer Communications2019,39,1:127
2The Chinese Society of Clinical Oncology(CSCO):Clinical guidelines for the diagnosis and treatment of gastric cancer,2021显示文摘There exist differences in the epidemiological characteristics,clinicopathological features,tumor biological characteristics,treatment patterns,and drug selections between gastric cancer patients from the Eastern and Western countries.The Chinese Society of Clinical Oncology(CSCO)has organized a panel of senior experts specializing in all sub-specialties of gastric cancer to compile a clinical guideline for the diagnosis and treatment of gastric cancer since 2016 and renews it annually.Taking into account regional differences,giving full consideration to the accessibility of diagnosis and treatment resources,these experts have conducted expert consensus judgment on relevant evidence and made various grades of recommendations for the clinical diagnosis and treatment of gastric cancer to reflect the value of cancer treatment and meeting health economic indexes in China.The 2021 CSCO Clinical Practice Guidelines for Gastric Cancer covers the diagnosis,treatment,follow-up,and screening of gastric cancer.Based on the 2020 version of the CSCO Chinese Gastric Cancer guidelines,this updated guideline integrates the results ofmajor clinical studies from China and overseas for the past year,focused on the inclusion of research data from the Chinese population for more personalized and clinically relevant recommendations.For the comprehensive treatment of non-metastatic gastric cancer,attentions were paid to neoadjuvant treatment.The value of perioperative chemotherapy is gradually becoming clearer and its recommendation level has been updated.For the comprehensive treatment of metastatic gastric cancer,recommendations for immunotherapy were included,and immune checkpoint inhibitors fromthird-line to the first-line of treatment for different patient groups with detailed notes are provided.Feng-Hua Wang Xiao-Tian Zhang Yuan-Fang Li Lei Tang Xiu-Juan Qu Jie-Er Ying Jun Zhang Ling-Yu Sun Rong-Bo Lin Hong Qiu Chang Wang Miao-Zhen Qiu Mu-Yan Cai QiWu Hao Liu Wen-Long Guan Ai-Ping Zhou Yu-Jing Zhang Tian-Shu Liu Feng Bi Xiang-Lin Yuan Sheng-Xiang Rao Yan Xin Wei-Qi Sheng Hui-Mian Xu Guo-Xin Li Jia-Fu Ji Zhi-Wei Zhou Han Liang Yan-Qiao Zhang Jing Jin Lin Shen Jin Li Rui-Hua Xu 2021Cancer Communications2021,41,8:97
3Efficacy and safety of bevacizumab plus chemotherapy in Chinese patients with metastatic colorectal cancer:a randomized phase Ⅲ ARTIST trial显示文摘The efficacy and safety of bevacizumab with modified irinotecan,leucovorin bolus,and 5-fluorouracil intravenous infusion(mIFL) in the first-line treatment of metastatic colorectal cancer(mCRC) has not been well evaluated in randomized clinical trials in Chinese patients.We conducted a phrase Ⅲ trial in which patients with previously untreated mCRC were randomized 2:1 to the mIFL [irinotecan(125 mg/m2),leucovorin(20 mg/m2) bolus,and 5-fluorouracil intravenous infusion(500 mg/m2) weekly for four weeks every six weeks] plus bevacizumab(5 mg/kg every two weeks) group and the mIFL group,respectively.Co-primary objectives were progression-free survival(PFS) and 6-month PFS rate.In total,214 patients were enrolled.Our results showed that addition of bevacizumab to mIFL significantly improved median PFS(4.2 months in the mIFL group vs.8.3 months in the bevacizumab plus mIFL group,P < 0.001),6-month PFS rate(25.0% vs.62.6%,P < 0.001),median overall survival(13.4 months vs.18.7 months,P = 0.014),and response rate(17% vs.35%,P = 0.013).Grades 3 and 4 adverse events included diarrhea(21% in the mIFL group and 26% in the bevacizumab plus mIFL group) and neutropenia(19% in the mIFL group and 33% in the bevacizumab plus mIFL group).No wound-healing complications or congestive heart failure occurred.Our results suggested that bevacizumab plus mIFL is effective and well tolerated as first-line treatment for Chinese patients with mCRC.Clinical benefit and safety profiles were consistent with those observed in pivotal phase Ⅲ trials with mainly Caucasian patients.Zhong-Zhen Guan Jian-Ming Xu Rong-Cheng Luo Feng-Yi Feng Li-Wei Wang Lin Shen Shi-Ying Yu Yi Ba Jun Liang Dong Wang Shu-Kui Qin Jie-Jun Wang Jing He Chuan Qi Rui-Hua Xu 2011Chinese Journal of Cancer2011,30,10:48
4Establishment of intestinal organoid cultures modeling injury-associated epithelial regeneration显示文摘The capacity of 3D organoids to mimic physiological tissue organization and functionality has provided an invaluable tool to model development and disease in vitro.However,conventional organoid cultures primarily represent the homeostasis of self-organizing stem cells and their derivatives.Here,we established a novel intestinal organoid culture system composed of 8 components,mainly including VPA,EPZ6438,LDN193189,and R-Spondin 1 conditioned medium,which mimics the gut epithelium regeneration that produces hyperplastic crypts following injury;therefore,these organoids were designated hyperplastic intestinal organoids(Hyper-organoids).Single-cell RNA sequencing identified different regenerative stem cell populations in our Hyper-organoids that shared molecular features with in vivo injury-responsive Lgr5+stem cells or Clu+revival stem cells.Further analysis revealed that VPA and EPZ6438 were indispensable for epigenome reprogramming and regeneration in Hyper-organoids,which functioned through epigenetically regulating YAP signaling.Furthermore,VPA and EPZ6438 synergistically promoted regenerative response in gut upon damage in vivo.In summary,our results demonstrated a new in vitro organoid model to study epithelial regeneration,highlighting the importance of epigenetic reprogramming that pioneers tissue repair.Molong Qu Liang Xiong Yulin Lyu Xiannian Zhang Jie Shen Jingyang Guan Peiyuan Chai Zhongqing Lin Boyao Nie Cheng Li Jun Xu Hongkui Deng 2021Cell Research2021,31,3:9
5Inhibition of CCL2 by bindarit alleviates diabetes-associated periodontitis by suppressing inflammatory monocyte infiltration and altering macrophage properties显示文摘Diabetes-associated periodontitis(DP)aggravates diabetic complications and increases mortality from diabetes.DP is caused by diabetes-enhanced host immune-inflammatory responses to bacterial insult.In this study,we found that persistently elevated CCL2 levels in combination with proinflammatory monocyte infiltration of periodontal tissues were closely related to DP.Moreover,inhibition of CCL2 by oral administration of bindarit reduced alveolar bone loss and increased periodontal epithelial thickness by suppressing periodontal inflammation.Furthermore,bindarit suppressed the infiltration of proinflammatory monocytes and altered the inflammatory properties of macrophages in the diabetic periodontium.This finding provides a basis for the development of an effective therapeutic approach for treating DP.Zongshan Shen Shuhong Kuang Min Zhang Xin Huang Jiayao Chen Meiliang Guan Wei Qin Hockin H.K.Xu Zhengmei Lin 2021Cellular & Molecular Immunology2021,18,9:6
6Mis-estimation of coronary lesions and rectification by SYNTAX score feedback for coronary revascularization appropriateness显示文摘Background::Imprecise interpretation of coronary angiograms was reported and resulted in inappropriate revascularization.Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery(SYNTAX)score is a comprehensive system to evaluate the complexity of the overall lesions.We hypothesized that a real-time SYNTAX score feedback from image analysts may rectify the mis-estimation and improve revascularization appropriateness in patients with stable coronary artery disease(CAD).Methods::In this single-center,historical control study,patients with stable CAD with coronary lesion stenosis≥50%were consecutively recruited.During the control period,SYNTAX scores were calculated by treating cardiologists.During the intervention period,SYNTAX scores were calculated by image analysts immediately after coronary angiography and were provided to cardiologists in real-time to aid decision-making.The primary outcome was revascularization deemed inappropriate by Chinese appropriate use criteria for coronary revascularization.Results::A total of 3245 patients were enrolled and assigned to the control group(08/2016-03/2017,n=1525)or the intervention group(03/2017-09/2017,n=1720).For SYNTAX score tertiles,17.9%patients were overestimated and 4.3%were underestimated by cardiologists in the control group.After adjustment,inappropriate revascularization significantly decreased in the intervention group compared with the control group(adjusted odds ratio[OR]:0.83;95%confidence interval[CI]:0.73-0.95;P=0.007).Both inappropriate percutaneous coronary intervention(adjusted OR:0.82;95%CI:0.74-0.92;P<0.001)and percutaneous coronary intervention utilization(adjusted OR:0.88;95%CI:0.79-0.98;P=0.016)decreased significantly in the intervention group.There was no significant difference in 1-year adverse cardiac events between the control group and the intervention group.Conclusions::Real-time SYNTAX score feedback significantly reduced inappropriate coronary revascularization in stable patients with CAD.Clinical trial registration::Nos.NCT03068858 and NCT02880605;http://gffzz1caf53c915c04334suw5cownpw56b66co.ffgz.tsg.suse.edu.cn.Shen Lin Heng Zhang Si-Peng Chen Chen-Fei Rao Fan Wu Fa-Jun Zhou Yun Wang Hong-Bing Yan Ke-Fei Dou Yong-Jian Wu Yi-Da Tang Li-Hua Xie Chang-Dong Guan Bo Xu Zhe Zheng 2020Chinese Medical Journal2020,,11:2
7Experimental and numerical study on instability structure of the supersonic mixing layer(M_c = 0.5)显示文摘The parameters of instability wave of supersonic mixing layer(Mc=0.5,M1=3.5/M2=1.4) are measured by flow visualization and calculated by means of two-dimensional direct numerical simulaitons of the compressible Navier-Stokes equations.In both cases of the mixing layer with harmonic disturbance or not,the comparative results indicate that the wavelength of the two-dimensional wave is equal to the vortex spacing in the streamwise direction because the difference between them is less than 1%.However,the measured convective velocity of the large-scale structure deviates from the theoretical isentropic prediction about 10%.Here the measured value confirms that Mc,2YANG WuBing ZHUANG FengGan SHEN Qing GUAN FaMing WANG Qiang YI ShiHe ZHAO YuXin HE Lin TIAN LiFeng 2009Science China(Physics,Mechanics & Astronomy)2009,52,10:2

9Wavelength-swept fiber laser based on bidirectional used linear chirped fiber Bragg grating显示文摘A wavelength-swept fiber laser is proposed and successfully demonstrated based on a bidirectional used linear chirped fiber Bragg grating(LC-FBG). The wavelength-swept operation principle is based on intracavity pulse stretching and compression. The LC-FBG can introduce equivalent positive and negative dispersion simultaneously, which enables a perfect dispersion matching to obtain wide-bandwidth mode-locking. Experimental results demonstrate a wavelength-swept fiber laser that exhibits a sweep rate of about 5.4 MHz over a 2.1 nm range at a center wavelength of 1550 nm. It has the advantages of simple configuration and perfect dispersion matching in the laser cavity.LIN WANG MINGGUI WAN ZHENKUN SHEN XUDONG WANG YUAN CAO XINHUAN FENG BAI-OU GUAN 2017Photonics Research2017,5,3:1

12iTRAQ-based quantitative proteomic analysis reveals key pathways responsible for scurs in sheep(Ovis aries)显示文摘Scurs is a horn phenotype that exhibits as small corneous structures on the skull due to the deformed development of horn tissues. Previous genome-wide association analysis of scurs in Soay sheep showed a significant association to the polled locus, relaxin-like receptor 2(RXFP2). However, the molecular mechanism underlying the development of scurs remains largely unknown. In the present study, we performed an i TRAQ-based quantitative proteomic analysis of horn tissues from both scurs and normal two-horned and four-horned individuals among Altay sheep to identify the differentially expressed proteins(DEPs) responsible for the scurs phenotype. In total, 232 proteins showed significant differential expression, and the most significant Gene ontology categories were the adhesion processes(biological adhesion(P=4.07×10–17) and cell adhesion(P=3.7×10–16)), multicellular organismal process(single-multicellular organism process(P=2.06×10–11) and multicellular organismal process(P=2.29×10–11)) and extracellular processes(extracellular matrix organization(P=4.77×10–16) and extracellular structure organization(P=4.93×10–16)). Kyoto encyclopedia of genes and genomes(KEGG) analysis showed that extracellular matrix(ECM)-receptor interactions and focal adhesion pathways were the most significant pathways. This finding is consistent with the reduced formation of extracellular matrix in scurs and the development of deformed horn tissues. Our study helps to elucidate the inheritance pattern of sheep horn traits from the perspectives of downstream expressed proteins.HE Xiao-hong CHEN Xiao-fei PU Ya-bin GUAN Wei-jun SONG Shen ZHAO Qian-jun LI Xiang-chen JIANG Lin MA Yue-hui 2018Journal of Integrative Agriculture2018,17,8:1
13Development of an Indirect ELISA Using Recombinant Truncated Envelope Glycoprotein for Detection of Antibodies against Japanese Encephalitis Virus显示文摘[Objective] To develop an indirect ELISA assay for detecting antibodies against envelope glycoprotein (E protein) of Japanese encephalitis virus (JEV). [Method] Specific primers were designed according to JEV sequences published in the GenBank. The cDNA of JEV E gene (about 1 000 bp) was amplified by the RT-PCR with the specific primers. After sequencing analysis, the E gene was cloned into pET30a expression vector and expressed in E. coli BL21(DE3) with the induction of IPTG. After denaturation, purification and renaturation, the recombinant protein was analyzed by the SDS-PAGE and the western blotting. An indirect ELISA was developed to detect antibodies against JEV. [Result] The E protein was mainly expressed in inclusion body. With the purified E protein, the indirect ELISA was developed and displayed good specificity, sensitivity and repeatability. [Conclusion]The developed ELISA using the truncated E protein as antigen is a simple, convenient and rapid serological method for diagnosis, monitoring antibody level and epidemiological investigation of JEV.ZU Li-chuang WANG Jin-liang GUAN Yu SHEN Zhi-qiang DONG Lin LI Jiao 2010Animal Husbandry and Feed Science2010,2,1:1

17Establishment and Application of a Real-time Fluorescent Quantitative PCR Method for Detection of Porcine Circovirus Type 2显示文摘[Objective]To establish a real-time fluorescent quantitative polymerase chain reaction(PCR) method with SYBR Green I for the detection of porcine circovirus type 2(PCV2).[Methods]Specific primers were designed to amplify the conserved gene segments of PCV2 with a size of 177 bp by PCR.The amplified gene was cloned into the vector of pMD~18-T and transformed into DH5α to screen positive clones.After being extracted and purified,the recombinant plasmids pMD~ 18-T-177 were taken as the standard DNA templates to establish the fluorescence quantitative PCR method for the detection of PCV2,and the PCR reaction conditions were optimized.[Results]Ct value of the established PCR method showed a good linear relationship with the standard DNA templates within a viral load of 3.21×10~0-4.16×10~8 copies /μL,the correlation coefficient was 0.998 8 and the slope was-3.286.The method did not show any cross-reactions with the genomes of PRRSV,PCV1,CSFV,PRV,PPV and Escherichia coli.Sensitivity of this method was proved to be 3.21×10° copies/μL,which was 1 000 times higher as conventional PCR method.Variation coefficients of the repeated trials among same batch or different batches were both less than 3.00%.Positive rate of clinical samples detected by the established PCR method was 58.94%,which was significantly higher than the detection rate by conventional PCR.[Conclusions]A real-time fluorescent quantitative PCR method with SYBR Green I for the detection of PCV2 was established,which was better for conducting the quantitative analysis and the early diagnosis of PCV2 infection.Dong Lin Wei Feng Guan Yu Liu Zengshan Shen Zhiqiang 2015Animal Husbandry and Feed Science2015,7,4:0
18Large area^(3)He tube array detector with modular design for multi‑physics instrument at CSNS显示文摘The multi-physics instrument(MPI)is the first user cooperative instrument at the China Spallation Neutron Source(CSNS).It was designed to explore the structures of complex materials at multiple scales based on the neutron total scattering technique.This imposes the requirements for the detector,including a high detection efficiency to reduce the measurement time and a large solid angle coverage to cover a wide range of momentum transfers.To satisfy these demands,a large-area array of 3He-filled linear position-sensitive detectors(LPSDs)was constructed,each with a diameter of 1 inch and pressure of 20 atm.It uses an orbicular layout of the detector and an eight-pack module design for the arrangement of 3He LPSDs,covering a range of scattering angles from 3°to 170°with a total detector area of approximately 7 m2.The detector works in air,which is separated from the vacuum environment to facilitate installation and maintenance.The characteristics of the MPI detector were investigated through Monte Carlo(MC)simulations using Geant4 and experimental measurements.The results suggest that the detectors are highly efficient in the wavelength range of the MPI,and an efficiency over 25%is achievable for above 0.1 A neutrons.A minimal position resolution of 6.4 mm full width at half maximum(FWHM)along the tube length was achieved at a working voltage of 2200 V,and a deviation below 2 mm between the real and measured positions was attained in the beam experiment.The detector module exhibited good consistency and an excellent counting rate capacity of up to 80 kHz,which satisfied the requirements of experiments with a high event rate.Observations of its operation over the past year have shown that the detector works steadily in sample experiments,which allows the MPI to serve the user program successfully.Lin Zhu Jian‑Rong Zhou Yuan‑Guang Xia Liang Xiao Hong Luo Xiao‑Juan Zhou Wen‑Qin Yang Bei‑Ju Guan Xing‑Fen Jiang Yan‑Feng Wang Hong Xu Hai‑Yun Teng Li‑Xin Zeng Jia‑Jie Li Lei Hu Ke Zhou Yong‑Xiang Qiu Pei‑Xun Shen Jun Xu Li‑Jiang Liao Xiao‑Zhuang Wang Gui‑An Yang Huai‑Chan Chen Ju‑Ping Xu Zhi‑Duo Li Song‑Lin Wang Jian Zhuang Yu‑Bin Zhao Jun‑Rong Zhang Wen Yin Zhi‑Jia Sun Yuan‑Bo Chen 2023Nuclear Science and Techniques2023,34,1:0
19Synergetic roadmap of carbon neutrality and clean air for China显示文摘It is well recognized that carbon dioxide and air pollutants share similar emission sources so that synergetic policies on climate change mitigation and air pollution control can lead to remarkable co-benefits on greenhouse gas reduction,air quality improvement,and improved health.In the context of carbon peak,carbon neutrality,and clean air policies,this perspective tracks and analyzes the process of the synergetic governance of air pollution and climate change in China by developing and monitoring 18 indicators.The 18 indicators cover the following five aspects:air pollution and associated weather-climate conditions,progress in structural transition,sources,inks,and mitigation pathway of atmospheric composition,health impacts and benefits of coordinated control,and synergetic governance system and practices.By tracking the progress in each indicator,this perspective presents the major accomplishment of coordinated control,identifies the emerging challenges toward the synergetic governance,and provides policy recommendations for designing a synergetic roadmap of Carbon Neutrality and Clean Air for China.Qiang Zhang Zhicong Yin Xi Lu Jicheng Gong Yu Lei Bofeng Cai Cilan Cai Qimin Chai Huopo Chen Hancheng Dai Zhanfeng Dong Guannan Geng Dabo Guan Jianlin Hu Cunrui Huang Jianing Kang Tiantian Li Wei Li Yongsheng Lin Jun Liu Xin Liu Zhu Liu Jinghui Ma Guofeng Shen Dan Tong Xuhui Wang Xuying Wang Zhili Wang Yang Xie Honglei Xu Tao Xue Bing Zhang Da Zhang Shaohui Zhang Shaojun Zhang Xian Zhang Bo Zheng Yixuan Zheng Tong Zhu Jinnan Wang Kebin He 2023Environmental Science and Ecotechnology2023,,4:0
20Global Pediatric Pulmonology Alliance recommendation to strengthen prevention of pediatric seasonal influenza under COVID-19 pandemic显示文摘The World Health Organization(WHO)announced COVID-19 as a global pandemic in March of 2020[1].The COVID-19 pandemic may persist for a long period of time.Global prevention and control becomes a complex and challenging task,and such efforts should be sustained.Although general measures,such as social distancing,face masks,respiratory hygiene and hand sanitization,will bear fruits for decreasing spread of other respiratory illnesses including influenza,the specific prevention through vaccination is a key focus especially in the upcoming winter and spring seasons[2].Kun-Ling Shen Leyla Namazova-Baranova Yong-Hong Yang Gary Wing Kin Wong Lanny J.Rosenwasser Lance E.Rodewald Anne Eng Neo Goh Eitan Kerem Chris O'Callaghan T.Bernard Kinane Basil Elnazir Rina Triasih Rosemary Horne Anne B Chang Jim Buttery Ruth A.Etzel Kazunobu Ouchi Hilary Hoey Varinder Singh Genesis C.Rivera Spencer SLi Yu Guan Ling Cao Yue-Jie Zheng Lu-Zhao Feng Wu Zhong Zheng-De Xie Bao-Ping Xu Rong-Jun Lin Gen Lu Qiang Qin Chun-Mei Zhu Su-Yun Qian Gang Liu Cheng-Song Zhao Zhuang Wei Yu-Hong Zhao Global Pediatric Pulmonology Alliance(GPPA)Expert Panel on Infectious Diseases&COVID-19 2020World Journal of Pediatrics2020,16,5:0
