| 1 | Towards 6G wireless communication networks:vision,enabling technologies,and new paradigm shifts显示文摘The fifth generation(5G)wireless communication networks are being deployed worldwide from 2020 and more capabilities are in the process of being standardized,such as mass connectivity,ultra-reliability,and guaranteed low latency.However,5G will not meet all requirements of the future in 2030 and beyond,and sixth generation(6G)wireless communication networks are expected to provide global coverage,enhanced spectral/energy/cost efficiency,better intelligence level and security,etc.To meet these requirements,6G networks will rely on new enabling technologies,i.e.,air interface and transmission technologies and novel network architecture,such as waveform design,multiple access,channel coding schemes,multi-antenna technologies,network slicing,cell-free architecture,and cloud/fog/edge computing.Our vision on 6G is that it will have four new paradigm shifts.First,to satisfy the requirement of global coverage,6G will not be limited to terrestrial communication networks,which will need to be complemented with non-terrestrial networks such as satellite and unmanned aerial vehicle(UAV)communication networks,thus achieving a space-airground-sea integrated communication network.Second,all spectra will be fully explored to further increase data rates and connection density,including the sub-6GHz,millimeter wave(mmWave),terahertz(THz),and optical frequency bands.Third,facing the big datasets generated by the use of extremely heterogeneous networks,diverse communication scenarios,large numbers of antennas,wide bandwidths,and new service requirements,6G networks will enable a new range of smart applications with the aid of artificial intelligence(AI)and big data technologies.Fourth,network security will have to be strengthened when developing 6G networks.This article provides a comprehensive survey of recent advances and future trends in these four aspects.Clearly,6G with additional technical requirements beyond those of 5G will enable faster and further communications to the extent that the boundary between physical and cyber worlds disappears. | Xiaohu YOU Cheng-Xiang WANG Jie HUANG Xiqi GAO Zaichen ZHANG Mao WANG Yongming HUANG Chuan ZHANG Yanxiang JIANG Jiaheng WANG Min ZHU Bin SHENG Dongming WANG Zhiwen PAN Pengcheng ZHU Yang YANG Zening LIU Ping ZHANG Xiaofeng TAO Shaoqian LI Zhi CHEN Xinying MA Chih-Lin I Shuangfeng HAN Ke LI Chengkang PAN Zhimin ZHENG Lajos HANZO Xuemin(Sherman)SHEN Yingjie Jay GUO Zhiguo DING Harald HAAS Wen TONG Peiying ZHU Ganghua YANG Jun WANG Erik GLARSSON Hien Quoc NGO Wei HONG Haiming WANG Debin HOU Jixin CHEN Zhe CHEN Zhangcheng HAO Geoffrey Ye LI Rahim TAFAZOLLI Yue GAO HVincent POOR Gerhard P.FETTWEIS Ying-Chang LIANG | 2021 | Science China(Information Sciences)2021，64，1： | 122 |
| 2 | The 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 | 2021 | Cancer Communications2021，41，8： | 97 |
| 3 | Down-Regulation of Neurocan Expression in Reactive Astrocytes Promotes Axonal Regeneration and Facilitates the Neurorestorative Effects of Bone Marrow Stromal Cells in the Ischemic Rat Brain显示文摘脑卒中后缺血组织边界形成胶质疤痕,抑制轴突再生。神经蛋白聚糖是一种轴突延长抑制分子,在卒中后胶质疤痕中表达上调。骨髓基质干细胞(BMSCs)可降低胶质疤痕壁的厚度,加速缺血周边区的轴突重塑。为了进一步明确BMSCs在轴突再生中的作用及机制,本文重点研究脑缺血组织中BMSCs对神经蛋白聚糖表达的作用。31只成年雄性Wistar大鼠大脑中动脉阻塞(MCAo)2 h,24 h后从中选择16只给予尾静脉注射3×106鼠BMSCs(BMSCs组),15只注射磷酸盐缓冲生理盐水(对照组)。缺血后8 d处死实验大鼠,免疫染色表明反应性星形胶质细胞是神经蛋白聚糖的原始来源,且BMSCs组缺血半暗带脑组织的神经聚糖表达明显低于对照组,生长相关蛋白43表达高于对照组,这在蛋白印迹分析中得到确认。为了进一步检测BMSCs在星形胶质细胞神经蛋白聚糖表达中的作用,用激光捕获显微切割法从缺血周边区收集单纯的反应性星形胶质细胞。BMSCs组的神经蛋白聚糖基因表达明显下调(n=4/组)。原代培养的星形胶质细胞也表现出相同改变,糖氧剥离的星形胶质细胞再给氧时与BMSCs共培养会抑制神经蛋白聚糖基因的表达上调(n=3/组)。本研究表明BMSCs通过下调梗死周边星形胶质细胞中神经蛋白聚糖的表达来促进轴突再生。 | LI HONG SHEN YI LI QI GAO SMITA SAVANT-BHONSALE AND MICHAEL CHOPP | 2008 | 神经损伤与功能重建2008，3，6： | 51 |
| 4 | 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up. | Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu | 2018 | Science Bulletin2018，63，23： | 54 |
| 5 | Activation of gibberellin 2-oxidase 6 decreases active gibberellin levels and creates a dominant semi-dwarf phenotype in rice (Oryza sativa L.)显示文摘Gibberellin (GA) 2-oxidase plays a key role in the GA catabolic pathway through 2β-hydroxylation.In the present study,we isolated a CaMV 35S-enhancer activation tagged mutant,H032.This mutant exhibited a dominant dwarf and GA-deficient phenotype,with a final stature that was less than half of its wild-type counterpart.The endogenous bioactive GAs are markedly decreased in the H032 mutant,and application of bioactive GAs (GA3 or GA4) can reverse the dwarf phenotype.The integrated T-DNA was detected 12.8 kb upstream of the OsGA2ox6 in the H032 genome by TAIL-PCR.An increased level of OsGA2ox6 mRNA was detected at a high level in the H032 mutant,which might be due to the enhancer role of the CaMV 35S promoter.RNAi and ectopic expression analysis of OsGA2ox6 indicated that the dwarf trait and the decreased levels of bioactive GAs in the H032 mutant were a result of the up-regulation of the OsGA2ox6 gene.BLASTP analysis revealed that OsGA2ox6 belongs to the class III of GA 2-oxidases,which is a novel type of GA2ox that uses C20-GAs (GA12 and/or GA53) as the substrates.Interestingly,we found that a GA biosynthesis inhibitor,paclobutrazol,positively regulated the OsGA2ox6 gene.Unlike the over-expression of OsGA2ox1,which led to a high rate of seed abortion,the H032 mutant retained normal flowering and seed production.These results indicate that OsGA2ox6 mainly affects plant stature,and the dominant dwarf trait of the H032 mutant can be used as an efficient dwarf resource in rice breeding. | Jian Huang Ding Tang Yi Shen Baoxiang Qin Lilan Hong Aiqing You Ming Li Xin Wang Hengxiu Yu Minghong Gu Zhukuan Cheng | 2010 | Journal of Genetics and Genomics2010，37，1： | 36 |
| 6 | Different treatment strategies and molecular features between right-sided and left-sided colon cancers显示文摘The colon is derived from the embryological midgut and hindgut separately,with the right colon and left colon having different features with regards to both anatomical and physiological characteristics.Cancers located in the right and left colon are referred to as right colon cancer(RCC) and left colon cancer(LCC),respectively,based on their apparent anatomical positions.Increasing evidence supports the notion that not only are there differences in treatment strategies when dealing with RCC and LCC,but molecular features also vary between them,not to mention the distinguishing clinical manifestations.Disease-free survival after radical surgery of both RCC and LCC are similar.In the treatment of RCC,the benefit gained from adjuvant FOLFIRI chemotherapy is superior,or at least similar,to LCC,but inferior to LCC if FOLFOX regimen is applied.On the other hand,metastatic LCC exhibits longer survival than that of RCC in a palliative chemotherapy setting.For KRAS wild-type cancers,LCC benefits more from cetuximab treatment than RCC.Moreover,advanced LCC shows a higher sensitivity to bevacizumab treatment in comparison with advanced RCC.Significant varieties exist at the molecular level between RCC and LCC,which may serve as the cause of all apparent differences.With respect to carcinogenesis mechanisms,RCC is associated with known gene types,such as MMR,KRAS,BRAF,and mi RNA-31,while LCC is associated with CIN,p53,NRAS,mi RNA-146 a,mi RNA-147 b,and mi RNA-1288.Regarding protein expression,RCC is related to GNAS,NQO1,telomerase activity,P-PDH,and annexin A10,while LCC is related to Topo I,TS,and EGFR.In addition,separated pathways dominate progressionto relapse in RCC and LCC.Therefore,RCC and LCC should be regarded as two heterogeneous entities,with this heterogeneity being used to stratify patients in order for them to have the optimal,current,and novel therapeutic strategies in clinical practice.Additional research is needed to uncover further differences between RCC and LCC. | Hong Shen Jiao Yang Qing Huang Meng-Jie Jiang Yi-Nuo Tan Jian-Fei Fu Li-Zhen Zhu Xue-Feng Fang Ying Yuan | 2015 | World Journal of Gastroenterology2015，21，21： | 33 |
| 7 | The state-of-the-art of the China Seismo-Electromagnetic Satellite mission显示文摘The China Seismo-Electromagnetic Satellite(CSES) mission was proposed in 2003 and approved in 2013 after ten years' scientific and engineering demonstrations. To meet the requirement of scientific objectives, the satellite is designed to be in a sunsynchronous orbit with an altitude of 507 km and descending node time of 14:00 LT. The CSES satellite carries 8 instruments,including search-coil magnetometer(SCM), electric field detector(EFD), high precision magnetometer(HPM), GNSS occultation receiver(GOR), plasma analyzer package(PAP), langmuir probe(LAP), high energetic particle package(HEPP) and detector(HEPD), and tri-band beacon(TBB), among which HEPD is provided by Italian Space Agency. The CSES satellite was launched successfully on February 2, 2018, and is planned to operate for 5 years. The CSES mission is the first satellite in China to measure geophysical fields, which will have a lot of application prospects in the study of seismology, geophysics, space sciences, and so on. | SHEN XuHui ZHANG XueMin YUAN ShiGeng WANG LanWei CAO JinBin HUANG JianPing ZHU Xing Hong PIERGIORGIO Picozzo DAI JianPing | 2018 | Science China(Technological Sciences)2018，61，5： | 33 |
| 8 | Anti-SARS-CoV-2 activities in vitro of Shuanghuanglian preparations and bioactive ingredients显示文摘Human infection with severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)causes coronavirus disease 2019(COVID-19)and there is no cure currently.The 3CL protease(3CLpro)is a highly conserved protease which is indispensable for CoVs replication,and is a promising target for development of broad-spectrum antiviral drugs.In this study we investigated the anti-SARS-CoV-2 potential of Shuanghuanglian preparation,a Chinese traditional patent medicine with a long history for treating respiratory tract infection in China.We showed that either the oral liquid of Shuanghuanglian,the lyophilized powder of Shuanghuanglian for injection or their bioactive components dose-dependently inhibited SARS-CoV-23CLpro as well as the replication of SARS-CoV-2 in Vero E6 cells.Baicalin and baicalein,two ingredients of Shuanghuanglian,were characterized as the first noncovalent,nonpeptidomimetic inhibitors of SARS-CoV-23CLpro and exhibited potent antiviral activities in a cell-based system.Remarkably,the binding mode of baicalein with SARS-CoV-23CLpro determined by X-ray protein crystallography was distinctly different from those of known 3CLpro inhibitors.Baicalein was productively ensconced in the core of the substrate-binding pocket by interacting with two catalytic residues,the crucial S1/S2 subsites and the oxyanion loop,acting as a“shield”in front of the catalytic dyad to effectively prevent substrate access to the catalytic dyad within the active site.Overall,this study provides an example for exploring the in vitro potency of Chinese traditional patent medicines and effectively identifying bioactive ingredients toward a specific target,and gains evidence supporting the in vivo studies of Shuanghuanglian oral liquid as well as two natural products for COVID-19 treatment. | Hai-xia Su Sheng Yao Wen-feng Zhao Min-jun Li Jia Liu Wei-juan Shang Hang Xie Chang-qiang Ke Hang-chen Hu Mei-na Gao Kun-qian Yu Hong Liu Jing-shan Shen Wei Tang Lei-ke Zhang Geng-fu Xiao Li Ni Dao-wen Wang Jian-ping Zuo Hua-liang Jiang Fang Bai Yan Wu Yang Ye Ye-chun Xu | 2020 | Acta Pharmacologica Sinica2020，41，9： | 32 |
| 9 | Clinical significance of K-ras and BRAF mutations in Chinese colorectal cancer patients显示文摘AIM:To identify and assess mutations in the K-ras and BRAF genes in a cohort of Chinese patients with colorectal cancer (CRC) for their association with various clinicopathological parameters and prognosis.METHODS:Genomic DNA was isolated from frozen tissues.Pyrosequencing analysis was conducted to detect mutations in the K-ras (codons 12,13,and 61) and BRAF genes (codon 600).Statistical analysis was carried out using SPSS-15.0 software.RESULTS:Among the 118 colorectal cancer patients,we detected 41 (34.7%) mutations in the K-ras gene.Mutation frequencies at codon 12 and codon 13 were 23.7% (28/118) and 10.2% (12/118),respectively.Only one patient harbored a point mutation at codon 61 (0.8%,1/118).Gender was the only factor that showed an obvious relationship with K-ras gene mutation (female 44.7% vs male 28.2%,P=0.037).Other clinicopathological features,such as age,location of the tumor,tumor differentiation,Tumor,Node and Metastases classification,and the Union for International Cancer Control staging,showed no positive relationship with K-ras gene mutations.No significant correlation was observed between the presence of K-ras mutations (codons 12,13,and 61) and the survival of the patients.BRAF mutations were rare,and only two patients (1.7%) harbored a detectable mutation at codon 600.CONCLUSION:K-ras gene mutation is a common event in our 118 Chinese CRC patients,with an obvious relationship with gender.However,it seems not to be an independent prognostic factor in CRC patients.The BRAF gene is rarely mutated in Chinese CRC patients. | Hong Shen Ying Yuan Han-Guang Hu Xiao-Xian Ye Mo- Dan Li Xian Zhong Wei-Jia Fang Shu Zheng | 2011 | World Journal of Gastroenterology2011，17，6： | 29 |
| 10 | Chemotherapy and target therapy for hepatocellular carcinoma:New advances and challenges显示文摘Primary liver cancer is one of the commonest causes of death.Hepatocellular carcinoma(HCC) accounts for 90% of primary liver cancers.For patients with unresectable or metastatic HCC,conventional chemotherapy is of limited or no benefit.Sorafenib is the only systemic treatment to demonstrate a statistically significant but modest overall survival benefit,leading to an era of targeted agents.Many clinical trials of targeted drugs have been carried out with many more in progress.Some drugs like PTK787 showed potential benefits in the treatment of HCC.Despite these promising breakthroughs,patients with HCC still have a dismal prognosis.Recently,both a phase Ⅲ trial of everolimus and a phase Ⅱ clinical trial of trebananib failed to demonstrate effective antitumor activity in advanced HCC.Sorafenib still plays a pivotal role in advanced HCC,leading to further explorations to exert its maximum efficacy.Combinations targeted with chemotherapy or transarterial chemoembolization is now being tested and might bring about advances.New targeted agents such as mammalian target of rapamycin inhibitors are under investigation,as well as further exploration of the mechanism of hepatocarcinogenesis. | Gan-Lu Deng Shan Zeng Hong Shen | 2015 | World Journal of Hepatology2015，7，5： | 30 |
| 11 | Puerarin protects brain tissue against cerebral ischemia/reperfusion injury by inhibiting the inflammatory response显示文摘Puerarin, a traditional Chinese medicine, exerts a powerful neuroprotective effect in cerebral ischemia/reperfusion injury, but its mechanism is unknown. Here, we established rat models of middle cerebral artery ischemia/reperfusion injury using the suture method. Puerarin(100 mg/kg) was administered intraperitoneally 30 minutes before middle cerebral artery occlusion and 8 hours after reperfusion. Twenty-four hours after reperfusion, we found that puerarin significantly improved neurological deficit, reduced infarct size and brain water content, and notably diminished the expression of Toll-like receptor-4, myeloid differentiation factor 88, nuclear factor kappa B and tumor necrosis factor-α in the ischemic region. These data indicate that puerarin exerts an anti-inflammatory protective effect on brain tissue with ischemia/reperfusion damage by downregulating the expression of multiple inflammatory factors. | Feng Zhou Liang Wang Panpan Liu Weiwei Hu Xiangdong Zhu Hong Shen Yuanyuan Yao | 2014 | Neural Regeneration Research2014，9，23： | 27 |

| 14 | A Strigolactone Biosynthesis Gene Contributed to the Green Revolution in Rice显示文摘Plant architecture is a complex agronomic trait and a major factor of crop yield,which is affected by several important hormones.Strigolactones(SLs)are identified as a new class hormoneinhibiting branching in many plant species and have been shown to be involved in various developmental processes.Genetical and chemical modulation of the SL pathway is recognized as a promising approach to modify plant architecture.However,whether and how the genes involved in the SL pathway could be utilized in breeding still remain elusive.Here,we demonstrate that a partial loss-of-function allele of the SL biosynthesis gene,HIGH TILLERING AND DWARF 1/DWARF17(HTD1/D17),which encodes CAROTENOID CLEAVAGE DIOXYGENASE 7(CCD7),increases tiller number and improves grain yield in rice.We found that the HTD1 gene had been widely utilized and co-selected with Semidwarf 1(SD1),both contributing to the improvement of plant architecture in modern rice varieties since the Green Revolution in the 1960s.Understanding how phytohormone pathway genes regulate plant architecture and how they have been utilized and selected in breeding will lay the foundation for developing the rational approaches toward improving crop yield. | Yuexing Wang Lianguang Shang Hong Yu Longjun Zeng Jiang Hu Shen Ni Yuchun Rao Sanfeng Li Jinfang Chu Xiangbing Meng Lei Wang Ping Hu Jijun Yan Shujing Kang Minghao Qu Hai Lin Tao Wang Quan Wang Xingming Hu Hongqi Chen Bing Wang Zhenyu Gao Longbiao Guo Dali Zeng Xudong Zhu Guosheng Xiong Jiayang Li Qian Qian | 2020 | Molecular Plant2020，13，6： | 23 |
| 15 | Quantification of angiogenesis by CT perfusion imaging in liver tumor of rabbit显示文摘BACKGROUND:Tumor angiogenesis is essential for primary and metastatic tumor growth.Computed tomography perfusion(CTP)is a new imaging method,made possible by the recent development of fast CT scanners and improved data analysis techniques,which allows measurement of the physiologic and hemodynamic properties of tissue vasculature.This study aimed to evaluate CTP in the quantification of angiogenesis and to assess the relationship between tissue perfusion parameters and microvascular density(MVD)and vascular endothelial growth factor(VEGF),attempting to detect the physiologic properties of angiogenesis.METHODS:Sixteen rabbits with VX2 liver tumors underwent multi-slice CT perfusion(MSCTP)on day 14 after tumor inoculation.CTP parameters included hepatic blood flow(HBF),hepatic blood volume(HBV),mean transit time(MTT),permeability of capillary vessel surface(PS),hepatic artery index(HAI),hepatic artery perfusion(HAP),and hepatic portal perfusion(HPP).The border of the tumor was stained with CD34 and VEGF immunohistochemical stains,and MVD was measured by anti-CD34.Then,CTP parameters were determined whether they were correlated with MVD and VEGF using Pearson’s correlation coefficient.RESULTS:The positive expression of MVD was different in the center and border of the tumor(P<0.01).There was a positive correlation between MVD and VEGF in the border(P<0.05).As more VEGF was expressed,the number of microvessels increased.Correlation analyses were also made between the perfusion parameters and MVD and VEGF in the border of the tumor.HBF,PS,HAI,and HAP values were positively correlated with MVD and VEGF(P<0.05),HPP was negatively correlated with MVD and VEGF(P<0.01),and HBV and MTT values were not correlated with MVD and VEGF(P>0.05).CONCLUSIONS:Significant correlations were found between perfusion parameters and MVD and VEGF.Therefore,MSCTP can be used to evaluate tumor angiogenesis in vivo. | Jiang, Hui-Jie Zhang, Zai-Ren Shen, Bao-Zhong Wan, Yong Guo, Hong Li, Jin-Ping | 2009 | Hepatobiliary & Pancreatic Diseases International2009，8，2： | 21 |

| 17 | The Chromosome-Level Genome Sequence of the Autotetraploid Alfalfa and Resequencing of Core Germplasms Provide Genomic Resources for Alfalfa Research显示文摘Alfalfa(Medicago sativa)is one of the most important forage crops in the world;however,its molecular genetics and breeding research are hindered due to the lack of a high-quality reference genome.Here,we report a de novo assembled 816-Mb high-quality,chromosome-level haploid genome sequence for‘Zhongmu No.1’alfalfa,a heterozygous autotetraploid.The contig N50 is 3.92 Mb,and 49165 genes are annotated in the genome.The alfalfa genome is estimated to have diverged from M.truncatula approximately 8 million years ago.Genomic population analysis of 162 alfalfa accessions revealed high genetic diversity,weak population structure,and extensive gene flow from wild to cultivated alfalfa.Genome-wide association studies identified many candidate genes associated with important agronomic traits.Furthermore,we showed that MsFTa2,a Flowering Locus T homolog,whose expression is upregulated in salt-resistant germplasms,may be associated with fall dormancy and salt resistance.Taken together,these genomic resources will facilitate alfalfa genetic research and agronomic improvement. | Chen Shen Huilong Du Zhuo Chen Hongwei Lu Fugui Zhu Hong Chen Xiangzhao Meng Qianwen Liu Peng Liu Lihua Zheng Xiuxiu Li Jiangli Dong Chengzhi Liang Tao Wang | 2020 | Molecular Plant2020，13，9： | 21 |
| 18 | Prognostic and survival analysis of 837 Chinese colorectal cancer patients显示文摘AIM:To develop a prognostic model to predict survival of patients with colorectal cancer (CRC). METHODS:Survival data of 837 CRC patients undergoing surgery between 1996 and 2006 were collected and analyzed by univariate analysis and Cox proportional hazard regression model to reveal the prognostic factors for CRC. All data were recorded using a standard data form and analyzed using SPSS version 18.0 (SPSS, Chicago, IL, United States). Survival curves were calculated by the Kaplan-Meier method. The log rank test was used to assess differences in survival. Univariate hazard ratios and significant and independent predictors of disease-specific survival and were identified by Cox proportional hazard analysis. The stepwise procedure was set to a threshold of 0.05. Statistical significance was defined asP < 0.05. RESULTS:The survival rate was 74% at 3 years and 68% at 5 years. The results of univariate analysis suggested age, preoperative obstruction, serum carcinoembryonic antigen level at diagnosis, status of resection, tumor size, histological grade, pathological type, lymphovascular invasion, invasion of adjacent organs, and tumor node metastasis (TNM) staging were positive prognostic factors (P < 0.05). Lymph node ratio (LNR) was also a strong prognostic factor in stage Ⅲ CRC (P < 0.0001). We divided 341 stage Ⅲ patients into three groups according to LNR values (LNR1, LNR ≤ 0.33, n = 211; LNR2, LNR 0.34-0.66, n = 76; and LNR3, LNR ≥ 0.67, n = 54). Univariate analysis showed a significant statistical difference in 3-year survival among these groups:LNR1, 73%; LNR2, 55%; and LNR3, 42% (P < 0.0001). The multivariate analysis results showed that histological grade, depth of bowel wall invasion, and number of metastatic lymph nodes were the most important prognostic factors for CRC if we did not consider the interaction of the TNM staging system (P < 0.05). When the TNM staging was taken into account, histological grade lost its statistical significance, while the specific TNM staging system showed a statistically significant difference (P < 0.0001). CONCLUSION:The overall survival of CRC patients has improved between 1996 and 2006. LNR is a powerful factor for estimating the survival of stage Ⅲ CRC patients. | Ying Yuan Mo-Dan Li Han-Guang Hu Cai-Xia Dong Jia-Qi Chen Xiao-Fen Li Jing-Jing Li Hong Shen | 2013 | World Journal of Gastroenterology2013，19，17： | 20 |
| 19 | Dendritic Cells Transduced with SOCS1 Gene Exhibit Regulatory DC Properties and Prolong Allograft Survival显示文摘SOCS1 is a key regulator of cytokine signaling and is important for maintaining balance in the immune system. It is thought to participate in negative feedback loops in cytokine signaling and may be an important signal for the regulation of dendritic cell (DC) maturation. However, it remains unclear whether DCs transduced with SOCS1 exhibit characteristics of regulatory DCs and induce allogeneic T-cell hyporesponsiveness. In this study, we constructed adenoviral vector coding SOCS1 (Ad-SOCS1) that can efficiently increase SOCS1 gene expression in bone marrow-derived dendritic cells. DCs transduced with Ad-SOCS1 (DC-SOCS1) expressed low levels of costimulatory and MHC molecules, were resistant to maturation and activation stimulation, induced allogeneic T-cell hyporesponsiveness, and promoted the generation of regulatory-like T cells in vitro. DC-SOCS1 pretreatment significantly prolonged the survival of allografts and led to a substantial increase in the generation of regulatory T cells. Our data suggest that SOCS1 inhibits DC maturation and induces regulatory DC generation, therefore possessing therapeutic potential to prevent rejection in organ transplantation. | Hong Fu Shaohua Song Fang Liu Zhijia Ni Xiaoyun Shen Liang Xiao Guoshan Ding Quanxing Wang | 2009 | Cellular & Molecular Immunology2009，6，2： | 20 |
| 20 | Suxiao Jiuxin pill promotes exosome secretion from mouse cardiac mesenchymal stem cells in vitro显示文摘心脏的间充质的干细胞(C-MSCs ) 是在损害以后在心修理起一个作用的内长的心脏的 stromal 房间。C-MSC-derived exosomes (Exo ) 对尖锐心肌的 ischemia/reperfusion 导致的 apoptosis 显示出保护的效果。Suxiao Jiuxin 药片(SJP ) 是为尖锐心肌的局部缺血的处理在中国使用的一个繁体中文药(TCM ) 公式,它作为主要部件包含 tetramethylpyrazine (TMP ) 和龙脑(BOR ) 。在这研究,我们调查了 SJP 处理是否在 vitro 从 C-MSCs 影响了 exosome 版本。从老鼠准备的 C-MSCs 与 SJP (62.5 g/mL ) 被对待, TMP (25 g/mL ) 或 BOR (15 g/mL ) 。用 acetylcholinesterase 活动试金,我们发现 SJP 和 TMP 处理显著地与控制乙醇处理相比增加了 exosome 分泌物。中立 sphingomyelinase 2 (nSMase2 ) 小径在 exosome 形成是重要的并且包装。但是 nSMase2 mRNA 的既不水平也不蛋白质的水平改变了后面的 SJP, TMP 或 BOR 处理,建议那 SJP 经由一条 nSMase2 独立的小径刺激了 exosome 版本。Rab27a 和 Rab27b GTPases 控制了 exosome 分泌物小径的不同步骤。我们证明 SJP 处理显著地与控制处理相比增加了 Rab27a, SYTL4 (Rab27a 受动器) 和 Rab27b 的蛋白质层次。SJP 处理另外显著地 upregulated Rab27b 的 mRNA 水平,而非 Rab27a。而且, C-MSC-exosome 版本的导致 SJP 的增加被 Rab27b 禁止击倒,建议那 SJP 经由一条 GTPase 依赖的小径从 C-MSCs 支持 exosome 分泌物。这研究在 modulating 为 SJP 揭示新奇机制心脏的动态平衡。 | Xiao-fen RUAN Cheng-wei JU Yan SHEN Yu-tao LIU II-man KIM Hong YU Neal WEINTRAUB Xiao-long WANG Yaoliang TANG | 2018 | Acta Pharmacologica Sinica2018，39，4： | 19 |
