| 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 | Multiple genetic alterations and behavior of cellular biology in gastric cancer and other gastric mucosal lesions:H.pylori infection,histological types and staging显示文摘AIM To investigate the expression of multiplegenes and the behavior of cellular biology ingastric cancer(GC)and other gastric mucosallesions and their relations to Helicobacter pylori(H.pylori)infection,tumor staging andhistological subtypes.METHODS Three hundred and twenty-sevenspecimens of gastric mucosa obtained viaendoscopy or surgical resection,and ABCimmunohistochemical staining were used todetect the expression of p53,p16,Bcl-2 andCOX-2 proteins.H.pylori was determined byrapid urea test combined with pathologicalstaining or14C urea breath test.Cellular image analysis was performed in 66 patients withintestinal metaplasia(IM)and/or dysplasia(Dys).In 30 of them,both cancer and theparacancerous tissues were obtained at the timeof surgery.Histological pattern,tumor staging,lymph node metastasis,grading ofdifferentiation and other clinical data werestudied in the medical records.RESULTS p16 expression of IM or Dys wassignificantly lower in positive H.pylori chronicatrophic gastritis(CAG)than those withnegative H.pylori(CAG:54.8% vs 88.0%,IM:34.4% vs 69.6%,Dys:23.8% vs 53.6%,allP<0.05),Bcl-2 or COX-2 expression of IM orDys in positive H.pylori cases was significantlyhigher than that without H.pylori(Bcl-2:68.8%vs23.9%,90.5% vs 60.7%;COX-2:50.0% vs10.8%,61.8% vs 17.8%;all P<0.05).Themean number of most parameters of cellularimage analysis in positive H.pylori group wassignificantly higher than that in negative H.pylori group(Ellipser:53±14,40±12μm,Area1:748±572,302±202 μm2,Area2:3050±1661,1681±1990 μm2,all P<0.05;Ellipseb:79±23,58±15 μm,Ratio1:22%±5%,13%±4%,Ratio2:79%±17%,53%±20%,all P<0.01).There was significant correlation between Bcl-2and histologic pattern of gastric carcinoma,andbetween COX-2 and tumor staging or lymph nodemetastasis(Bcl-2:75.0% vs 16.7%;COX-2:76.0% vs 20.0%,79.2% vs 16.7%;allP<0.05).CONCLUSION p1l6, Bcl-2, and COX-2 but not p53 gene may play a role in the early genesis/ progression of gastric carcinoma and are associated with H. pylori infection. p53 gene is relatively late event in gastric tumorigenesis and mainly relates to its progression. There is more cellular-biological behavior of malignant tumor in gastric mucosal lesions with H. pylori infection. Aberrant Bcl-2 protein expression appears to be preferentially associated with the intestinal type cancer. COX-2 seems to be related to tumor staging and lymph node metastasis. | Heng Jun Gao Lian Zhen Yu Jian Feng Bai Yan Shen Peng Gu Sun Han Lin Zhao Kun Miu Xiu Zhen Lü Xiao Yong Zhang Zhi Quan Zhao | 2000 | World Journal of Gastroenterology2000，6，6： | 52 |

| 6 | Recovery of iron from high phosphorus oolitic iron ore using coal-based reduction followed by magnetic separation显示文摘Oolitic iron ore is one of the most important iron resources. This paper reports the recovery of iron from high phosphorus oolitic iron ore using coal-based reduction and magnetic separation. The influences of reduction temperature, reduction time, C/O mole ratio, and CaO content on the metallization degree and iron recovery were investigated in detail. Experimental results show that reduced products with the metallization degree of 95.82% could be produced under the optimal conditions (i.e., reduction temperature, 1250℃; reduction time, 50 min; C/O mole ratio, 2.0; and CaO content, 10wt%). The magnetic concentrate containing 89.63wt% Fe with the iron recovery of 96.21% was obtained. According to the mineralogical and morphologic analysis, the iron minerals had been reduced and iron was mainly enriched into the metallic iron phase embedded in the slag matrix in the form of spherical particles. Apatite was also reduced to phosphorus, which partially migrated into the metallic iron phase. | Yong-sheng Sun Yue-xin Han Peng Gao Ze-hong Wang Duo-zhen Ren | 2013 | International Journal of Minerals,Metallurgy and Materials2013，20，5： | 43 |

| 8 | Plasma exchange-centered artificial liver support system in hepatitis B virus-related acute-onchronic liver failure:a nationwide prospective multicenter study in China显示文摘BACKGROUND:Plasma exchange(PE)-centered artificial liver support system reduced the high mortality rate of hepatitis B virus(HBV)-related acute-on-chronic liver failure(ACLF).But the data were diverse in different medical centers.The present prospective nationwide study was to evaluate the effects of PE on patients with HBV-ACLF at different stages.METHODS:From December 2009 to December 2011,we evaluated 250 patients at different stages of HBV-ACLF from 10 major medical centers in China.All the laboratory parameters were collected at admission,before and after PE.RESULTS:Among the 250 patients who underwent 661 rounds of PE,one-month survival rate was 61.6%; 141(56.4%) showed improvement after PE.Variables such as age(P=0.000),levels of total bilirubin(TB,P=0.000),direct bilirubin(P=0.000),total triglycerides(P=0.000),low-density lipoprotein(P=0.022),Na+(P=0.014),Cl–(P=0.038),creatinine(Cr,P=0.007),fibrinogen(P=0.000),prothrombin time(PT,P=0.000),white blood cell(P=0.000),platelet(P=0.003) and MELD(P=0.000) were significantly related to prognosis.Multivariate logistic regression analysis showed that age,disease stage,TB,Cr and PT levels were independent risk factors of mortality among HBV-ACLF patients.CONCLUSIONS:PE can improve the clinical outcome of patients with HBV-ACLF.Levels of TB,Cr and PT,age and disease stage help to predict prognosis. | Jia-Jia Chen Jian-Rong Huang Qian Yang Xiao-Wei Xu Xiao-Li Liu Shao-Rui Hao Hui-Fen Wang Tao Han Jing Zhang Jian-He Gan Zhi-Liang Gao Yu-Ming Wang Shu-Mei Lin Qing Xie Chen Pan Lan-Juan Li | 2016 | Hepatobiliary & Pancreatic Diseases International2016，15，3： | 48 |
| 9 | Distribution and assessment of heavy metals in the surface sediment of Yellow River, China显示文摘Large amounts of heavy metals discharged by industrial cities that are located along the middle reach of Yellow River, China have detrimental impacts on both the ecological environment and human health. In this study, fourteen surface sediment samples were taken in the middle reach of the Yellow River. Contents of Zn, Pb, Ni, Cu, Cr, Cd, As were measured, and the pollution status was assessed using three widely used pollution assessment methods, including the single factor index method, Nemerow pollution index method and potential ecological risk index. The concentrations of the studied heavy metals followed the order: Zn > Cr > Cu > Ni > Pb > As > Cd. Nearly 50% of sites had Cu and Cr accumulation. The concentration of Cu at the Yiluo River exceeded the secondary standard value of the Environmental quality standard for soils. Comparison of heavy metal concentrations between this study and other selected rivers indicated that Cu and Cr may be the major pollutants in our case. The single factor index indicated that many samples were at high levels of pollution for Cu and Cd; the Nemerow pollution index indicated that the Yihe River, Luohe River, Yiluo River and Huayuankou were polluted. According to the results of potential ecological risk assessment, Cd in the tributaries of Luo River, Yihe River,and Yiluo River showed high risk toward the ecosystem and human health, Cd in Huanyuankou and Cu in Yiluo River showed a middle level of risk and other samples were at a low level of risk. | Nan Yan Wenbin Liu Huiting Xie Lirong Gao Ying Han Mengjing Wang Haifeng Li | 2016 | Journal of Environmental Sciences2016，28，1： | 33 |
| 10 | Performance of RegCM4 over Major River Basins in China显示文摘A long-term simulation for the period 1990–2010 is conducted with the latest version of the International Centre for Theoretical Physics' Regional Climate Model(RegCM4), driven by ERA-Interim boundary conditions at a grid spacing of 25 km. The Community Land Model(CLM) is used to describe land surface processes, with updates in the surface parameters,including the land cover and surface emissivity. The simulation is compared against observations to evaluate the model performance in reproducing the present day climatology and interannual variability over the 10 main river basins in China,with focus on surface air temperature and precipitation. Temperature and precipitation from the ERA-Interim reanalysis are also considered in the model assessment. Results show that the model reproduces the present day climatology over China and its main river basins, with better performances in June–July–August compared to December–January–February(DJF).In DJF, we find a warm bias at high latitudes, underestimated precipitation in the south, and overestimated precipitation in the north. The model in general captures the observed interannual variability, with greater skill for temperature. We also find an underestimation of heavy precipitation events in eastern China, and an underestimation of consecutive dry days in northern China and the Tibetan Plateau. Similar biases for both mean climatology and extremes are found in the ERA-Interim reanalysis, indicating the difficulties for climate models in simulating extreme monsoon climate events over East Asia. | Xuejie GAO Ying SHI Zhenyu HAN Meili WANG Jia WU Dongfeng ZHANG Ying XU Filippo GIORGI | 2017 | Advances in Atmospheric Sciences2017，34，4： | 33 |

| 12 | Future changes in thermal comfort conditions over China based on multi-RegCM4 simulations显示文摘使用4个不同全球模式模拟结果,驱动RegCM4区域气候模式,进行了RCP4.5中等温室气体排放情景下东亚地区21世纪气候变化的高分辨率(25 km)模拟。本文基于此套模拟集合,使用综合考虑了气温、相对湿度和风速因素的人体热感受指数有效温度(ET),给出了未来中国区域热舒适条件的变化。分析中同时考虑了未来人口数量和分布情景所引起的暴露度变化。研究发现,未来中国区域的ET的普遍升高引起炎热天气的人口暴露度大幅度增加(到21世纪末相对于当代全国平均将增加6倍‘人-天’(person–days),凉、冷和寒冷天气的暴露度则减少。同时尽管舒适日数有所增加,但相应的人-天数目则有22%的减少。不同因素(气候、人口和两者的相互作用)对于上述变化的贡献分析表明,在舒适度的热端,气候因素的作用更重要,而人口因素则在冷端起着主导作用。总体而言,即使是在中等水平温室气体排放情景下,中国区域未来的热强度也将增加,尽管结果表现出很强的地理依赖特征。相对使用单纯气候因素的结果,人口暴露度的引入对变化信号有着强烈的调制作用,从而更加强调了在与气候变化相关的风险评估分析中,考虑社会-经济因素的重要性。 | GAO Xue-Jie WU Jie SHI Ying WU Jia HAN Zhen-Yu ZHANG Dong-Feng TONG Yao LI Rou-Ke XU Ying GIORGI Filippo | 2018 | Atmospheric and Oceanic Science Letters2018，11，4： | 30 |
| 13 | Differences in symptoms and pre-hospital delay among acute myocardial infarction patients according to ST-segment elevation on electrocardiogram: an analysis of China Acute Myocardial Infarction (CAMI) registry显示文摘Background: Approximately 70% patients with acute myocardial infarction (AMI) presented without ST-segment elevation on electrocardiogram. Patients with non-ST segment elevation myocardial infarction (NSTEMI) often presented with atypical symptoms, which may be related to pre-hospital delay and increased risk of mortality. However, up to date few studies reported detailed symptomatology of NSTEMI, particularly among Asian patients. The objective of this study was to describe and compare symptoms and presenting characteristics of NSTEMI vs. STEMI patients. Methods: We enrolled 21,994 patients diagnosed with AMI from China Acute Myocardial Infarction (CAMI) Registry between January 2013 and September 2014. Patients were divided into 2 groups according to ST-segment elevation: ST-segment elevation (STEMI) group and NSTEMI group. We extracted data on patients' characteristics and detailed symptomatology and compared these variables between two groups. Results: Compared with patients with STEMI (N=16,315), those with NSTEMI (N=5679) were older, more often females and more often have comorbidities. Patients with NSTEMI were less likely to present with persistent chest pain (54.3% vs.71.4%), diaphoresis (48.6% vs.70.0%), radiation pain (26.4% vs.33.8%), and more likely to have chest distress (42.4% vs.38.3%) than STEMI patients (all P<0.0001). Patients with NSTEMI were also had longer time to hospital. In multivariable analysis, NSTEMI was independent predictor of presentation without chest pain (odds ratio: 1.974, 95% confidence interval:1.849-2.107). Conclusions: Patients with NSTEMI were more likely to present with chest distress and pre-hospital patient delay compared with patients with STEMI. It is necessary for both clinicians and patients to learn more about atypical symptoms of NSTEMI in order to rapidly recognize myocardial infarction. | Rui Fu Chen-Xi Song Ke-Fei Dou Jin-Gang Yang Hai-Yan Xu Xiao-Jin Gao Qian-Qian Liu Han Xu Yue-Jin Yang | 2019 | Chinese Medical Journal2019，，5： | 29 |
| 14 | Antidiabetic Effects of Gegen Qinlian Decoction via the Gut Microbiota Are Attributable to Its Key Ingredient Berberine显示文摘Gegen Qinlian Decoction(GQD),a traditional Chinese medicine(TCM)formula,has long been used for the treatment of common metabolic diseases,including type 2 diabetes mellitus.However,the main limitation of its wider application is ingredient complexity of this formula.Thus,it is critically important to identify the major active ingredients of GQD and to illustrate mechanisms underlying its action.Here,we compared the effects of GQD and berberine,a hypothetical key active pharmaceutical ingredient of GQD,on a diabetic rat model by comprehensive analyses of gut microbiota,short-chain fatty acids,proinflammatory cytokines,and ileum transcriptomics.Our results show that berberine and GQD had similar effects on lowering blood glucose levels,modulating gut microbiota,inducing ileal gene expression,as well as relieving systemic and local inflammation.As expected,both berberine and GQD treatment significantly altered the overall gut microbiota structure and enriched many butyrate-producing bacteria,including Faecalibacterium and Roseburia,thereby attenuating intestinal inflammation and lowering glucose.Levels of short-chain fatty acids in rat feces were also significantly elevated after treatment with berberine or GQD.Moreover,concentration of serum proinflammatory cytokines and expression of immune-related genes,including Nfkb1,Stat1,and Ifnrg1,in pancreatic islets were significantly reduced after treatment.Our study demonstrates that the main effects of GQD can be attributed to berberine via modulating gut microbiota.The strategy employed would facilitate further standardization and widespread application of TCM in many diseases. | Xizhan Xu Zezheng Gao Fuquan Yang Yingying Yang Liang Chen Lin Han Na Zhao Jiayue Xu Xinmiao Wang Yue Ma Lian Shu Xiaoxi Hu Na Lyu Yuanlong Pan Baoli Zhu Linhua Zhao Xiaolin Tong Jun Wang | 2020 | Genomics, Proteomics & Bioinformatics2020，18，6： | 29 |
| 15 | Panax notoginseng saponins ameliorates experimental hepatic fibrosis and hepatic stellate cell proliferation by inhibiting the Jak2/Stat3 pathways显示文摘OBJECTIVE: To investigate the inhibitory effect of Panax notoginseng saponins(PNS) on liver fibrosis and explore the underlying mechanisms.METHODS: Carbon tetrachloride(CCl4)-treated rats and hepatic stellate cells(HSCs) were used. The effect of PNS on CCl4-induced liver fibrosis was studied with histochemical and biochemical analysis.Transforming growth factor(TGF)-β1, α-smooth muscle actin(α-SMA), and collagen Ι m RNA expression were determined by reverse transcriptase-polymerase chain reaction(RT-PCR). Meanwhile, the protein expression levels of α-SMA, collagen Ι, phosphorylation-Janus activated kinase signal transducer(p-Jak2) / Jak2, and phosphorylation-activator of transcription(p-Stat)3 / Stat3 were determined by immunohistochemistry and / or immunoblotting.RESULTS: PNS treatment significantly improved the liver function of rats as indicated by decreased serum enzymatic activities of alanine aminotransferase and aspartate aminotransferase. Histopathological results indicated that PNS alleviated liver damage and reduced the formation of fibrous septa. Moreover, PNS significantly decreased liver hydroxyproline and significantly attenuated expressions of collagen Ⅰ, α-SMA, TGF-β1, p-Jak2 / Jak2,and p-Stat3 / Stat3 in the rat liver fibrosis model and HSCs.CONCLUSION: PNS can relieve liver fibrosis by modulating Jak2/Stat3 signaling transduction pathway, which may be one of its mechanisms to suppress hepatic fibrosis. | Jiang Hui Gao Jiarong Wang Yongzhong Zhang Jiafu Han Yanquan Wei Liangbing Liu Xiaochuang Wu Jian | 2016 | Journal of Traditional Chinese Medicine2016，36，2： | 28 |

| 19 | Collagen scaffolds modified with collagen-binding bFGF promotes the neural regeneration in a rat hemisected spinal cord injury model显示文摘Nerve conduit is one of strategies for spine cord injury(SCI)treatment.Recently,studies showed that biomaterials could guide the neurite growth and promote axon regeneration at the injury site.However,the scaffold by itself was difficult to meet the need of SCI functional recovery.The basic fibroblast growth factor(bFGF)administration significantly promotes functional recovery after organ injuries.Here,using a rat model of T9 hemisected SCI,we aimed at assessing the repair capacity of implantation of collagen scaffold(CS)modified by collagen binding bFGF(CBD-bFGF).The results showed that CS combined with CBD-bFGF treatment improved survival rates after the lateral hemisection SCI.The CS/CBD-bFGF group showed more significant improvements in motor than the simply CS-implanted and untreated control group,when evaluated by the 21-point Basso-Beattie-Bresnahan(BBB)score and footprint analysis.Both hematoxylin and eosin(H&E)and immunohistochemical staining of neurofilament(NF)and glial fibrillary acidic protein(GFAP)demonstrated that fibers were guided to grow through the implants.These findings indicated that administration of CS modified with CBD-bFGF could promote spinal cord regeneration and functional recovery. | SHI Qin GAO Wei HAN XingLong ZHU XueSong SUN Jie XIE Fang HOU XiangLin YANG HuiLin DAI JianWu CHEN Liang | 2014 | Science China(Life Sciences)2014，57，2： | 23 |
| 20 | Age-related rhesus macaque models of COVID-19显示文摘Background:Since December 2019,an outbreak of the Corona Virus disease 2019(COVID-19)caused by severe acute respiratory syndrome coronavirus(SARS-CoV-2)in Wuhan,China,has become a public health emergency of international concern.The high fatality of aged cases caused by SARS-CoV-2 was a need to explore the possible age-related phenomena with non-human primate models.Methods:Three 3-5 years old and two 15 years old rhesus macaques were intratracheally infected with SARS-CoV-2,and then analyzed by clinical signs,viral replication,chest X-ray,histopathological changes and immune response.Results:Viral replication of nasopharyngeal swabs,anal swabs and lung in old monkeys was more active than that in young monkeys for 14 days after SARS-CoV-2 challenge.Monkeys developed typical interstitial pneumonia characterized by thickened alveolar septum accompanied with inflammation and edema,notably,old monkeys exhibited diffuse severe interstitial pneumonia.Viral antigens were detected mainly in alveolar epithelial cells and macrophages.Conclusion:SARS-CoV-2 caused more severe interstitial pneumonia in old monkeys than that in young monkeys.Rhesus macaque models infected with SARS-CoV-2 provided insight into the pathogenic mechanism and facilitated the development of vaccines and therapeutics against SARS-CoV-2 infection. | Pin Yu Feifei Qi Yanfeng Xu Fengdi Li Peipei Liu Jiayi Liu Linlin Bao Wei Deng Hong Gao Zhiguang Xiang Chong Xiao Qi Lv Shuran Gong Jiangning Liu Zhiqi Song Yajin Qu Jing Xue Qiang Wei Mingya Liu Guanpeng Wang Shunyi Wang Haisheng Yu Xing Liu Baoying Huang Wenling Wang Li Zhao Huijuan Wang Fei Ye Weimin Zhou Wei Zhen Jun Han Guizhen Wu Qi Jin Jianwei Wang Wenjie Tan Chuan Qin | 2020 | Animal Models and Experimental Medicine2020，3，1： | 22 |
