3Towards 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 2021Science China(Information Sciences)2021,64,1:122

8Chimeric antigen receptor-modified T cells for the immunotherapy of patients with EGFR-expressing advanced relapsed/refractory non-small cell lung cancer显示文摘The successes achieved by chimeric antigen receptor-modified T(CAR-T) cells in hematological malignancies raised the possibility of their use in non-small lung cancer(NSCLC). In this phase I clinical study(NCT01869166), patients with epidermal growth factor receptor(EGFR)-positive(>50% expression), relapsed/refractory NSCLC received escalating doses of EGFR-targeted CAR-T cell infusions. The EGFR-targeted CAR-T cells were generated from peripheral blood after a 10 to 13-day in vitro expansion. Serum cytokines in peripheral blood and copy numbers of CAR-EGFR transgene in peripheral blood and in tissue biopsy were monitored periodically. Clinical responses were evaluated with RECIST1.1 and immune-related response criteria, and adverse events were graded with CTCAE 4.0. The EGFR-targeted CAR-T cell infusions were well-tolerated without severe toxicity. Of 11 evaluable patients, two patients obtained partial response and five had stable disease for two to eight months. The median dose of transfused CAR+ T cells was 0.97×10~7 cells kg^(-1)(interquartile range(IQR), 0.45 to 1.09×10~7 cells kg^(-1)). Pathological eradication of EGFR positive tumor cells after EGFR-targeted CAR-T cell treatment can be observed in tumor biopsies, along with the CAR-EGFR gene detected in tumor-infiltrating T cells in all four biopsied patients. The EGFR-targeted CAR-T cell therapy is safe and feasible for EGFR-positive advanced relapsed/refractory NSCLC.Kaichao Feng Yelei Guo Hanren Dai Yao Wang Xiang Li Hejin Jia Weidong Han 2016Science China(Life Sciences)2016,59,5:62

11Effects of AT1 receptor antagonist,Iosartan,on rat hepatic fibrosis induced by CCl_4显示文摘AIM To investigate effect of losartan,an AT1receptor antagonist,on hepatic fibrosis induced byCCl;and to determine whether or not AT1receptors are expressed on hepatic stellate cells,METHODS AND RESULTS Fifty male Sprague-Dawley rats,weighing(180±20)g,wererandomized into five groups(control group,modelgroup,and three losartan treated groups),inwhich all rats were given the subcutaneousinjection of 40% CCl4(every 3 days for 6 weeks)except for rats of control group.Rats of losartan-treated groups were treated with losartan(20 mg/kg,10 mg/kg,5 mg/kg,daily gavage),After 6weeks liver tissue and serum samples of all ratswere examined.Serum hyaluronic acid(HA),procollagen typeⅢ(PCⅢ)were detected byradioimmunoassays,van Giesion collagen stainingwas used to evaluate the extracellular matrix of ratswith liver fibrosis.The expression of AT1receptors,transforming growth factor-beta(TGF-β),and alpha-smooth muscle actin(a-SMA)inliver tissue were determined byimmunohistochemical techniques.Compared withmodel group,serum ALT and AST of losartan-treated groups were significantly reduced(t=4.20,P<0.01 and t=4.57,P<0.01).Serum HAand PCⅢalso had significant differences(t=3.53,P<0.01 and t=2.20,P<0.05).Thedegree of fibrosis was improved by losartan and correlated with the expressions of AT1 receptors,TGF-β,and α-SMA in liver tissue.CONCLUSION AT1 receptor antagonist,losartan,could limit the progression of the hepatic fibrosisinduced by CCl4.The mechanism may be related tothe decrease in the expression of AT1 receptorsand TGF-β,ameliorating the injury of hepatocytes;activation of local renin-angiotensin system mightrelate to hepatic fibrosis;and during progressionof fibrosis,activated hepatic stellate cells mightexpress AT1 receptors.Hong Shan Wei Ding Guo Li Han Ming Lu Yu Tao Zhan Zhi Rong Wang Xin Huang Jing Zhang Ji Lin Cheng Qin Fang Xu Department of Gastroenterology,Xinhua Hospital,Shanghai Second Medical University,Shanghai 200092,China 2000World Journal of Gastroenterology2000,6,4:42
12Cold-chain transportation in the frozen food industry may have caused a recurrence of COVID-19 cases in destination:Successful isolation of SARS-CoV-2 virus from the imported frozen cod package surface显示文摘Coronavirus disease 2019(COVID-19)pandemic has spread in 220 countries/regions towreak havoc to human beings around theworld.At present,the second wave of COVID-19 has begun in many European countries.The complete control of COVID-19 is very urgent.Although China quickly brought the virus under control,there have been eight sporadic outbreaks in China since then.Both in Xinfadi of Beijing and Dalian outbreak of COVID-19,environmental swab samples related to imported cold chain food were tested nucleic acid positive for SARS-CoV-2.In this outbreak in Qingdao,we directly isolated SARS-CoV-2 from the cod outer package's surface swab samples.This is the first time worldwide,SARS-CoV-2 were isolated from the imported frozen cod outer package's surface,which showed that imported frozen food industry could import SARS-CoV-2 virus.Peipei Liu Mengjie Yang Xiang Zhao Yuanyuan Guo Liang Wang Jing Zhang Wenwen Lei Weifang Han Fachun Jiang William J.Liu George F.Gao Guizhen Wu 2020Biosafety and Health2020,2,4:41
13Field experiment on a robust hierarchical metropolitan quantum cryptography network显示文摘A hierarchical metropolitan quantum cryptography network upon the inner-city commercial telecom fiber cables is reported in this paper. The seven-user network contains a four-node backbone net with one node acting as the subnet gateway, a two-user subnet and a single-fiber access link, which is realized by the Faraday-Michelson interferometer set-ups. The techniques of the quantum router, optical switch and trusted relay are assembled here to guarantee the feasibility and expandability of the quantum cryptography network. Five nodes of the network are located in the government departments and the secure keys generated by the quantum key distribution network are utilized to encrypt the instant video, sound, text messages and confidential files transmitting between these bureaus. The whole implementation including the hierarchical quantum cryptographic communication network links and the corresponding application software shows a big step toward the practical user-oriented network with a high security level.XU FangXing CHEN Wei WANG Shuang YIN ZhenQiang ZHANG Yang LIU Yun ZHOU Zheng ZHAO YiBo LI HongWei LIU Dong HAN ZhengFu GUO GuangCan 2009Chinese Science Bulletin2009,54,17:40
14Molecular Cytogenetic Characterization of Wheat-Thinopyrum elongatum Addition,Substitution and Translocation Lines with a Novel Source of Resistance to Wheat Fusarium Head Blight显示文摘Thinopyrum elongatum(2n = 2x = 14,EE),a wild relative of wheat,has been suggested as a potentially novel source of resistance to several major wheat diseases including Fusarium Head Blight(FHB).In this study,a series of wheat(cv.Chinese Spring,CS) substitution and ditelosomic lines,including Th.elongatum additions,were assessed for TypeⅡresistance to FHB.Results indicated that the lines containing chromosome 7E of Th.elongatum gave a high level of resistance to FHB,wherein the infection did not spread beyond the inoculated floret.Furthermore,it was determined that the novel resistance gene(s) of 7E was located on the short-arm(7ES) based on sharp difference in FHB resistance between the two 7E ditelosomic lines for each arm.On the other hand,Th.elongatum chromosomes 5E and 6E likely contain gene(s) for susceptibility to FHB because the disease spreads rapidly within the inoculated spikes of these lines. Genomic in situ hybridization(GISH) analysis revealed that the alien chromosomes in the addition and substitution lines were intact,and the lines did not contain discernible genomic aberrations.GISH and multicolor-GISH analyses were further performed on three translocation lines that also showed high levels of resistance to FHB.Lines TA3499 and TA3695 were shown to contain one pair of wheat-Th. elongatum translocated chromosomes involving fragments of 7D plus a segment of the 7E,while line TA3493 was found to contain one pair of wheat-Th.elongatum translocated chromosomes involving the D- and A-genome chromosomes of wheat.Thus,this study has established that the short-arm of chromosome 7E of Th.elongatum harbors gene(s) highly resistant to the spreading of FHB,and chromatin of 7E introgressed into wheat chromosomes largely retained the resistance,implicating the feasibility of using these lines as novel material for breeding FHB-resistant wheat cultivars.Shulan Fu Zhenling Lv Bao Qi Xiang Guo Jun Li Bao Liu Fangpu Han 2012Journal of Genetics and Genomics2012,39,2:35

16Chinese deserts and sand fields in Last Glacial Maximum and Holocene Optimum显示文摘The Last Glacial Maximum (LGM, c. 26-16 ka) and the Holocene Optimum (HO, c. 9-5 ka) were characterized by cold-dry and warm-wet climates respectively in the recently geological Earth. How Chinese deserts and sand fields responded to these distinctive climatic changes is still not clear, however. To reconstruct environments of the deserts and sand fields during the LGM and HO is helpful to understand the forcing mechanisms of environment change in this arid region, and to test paleoclimatic modeling results. Through our long-term field and laboratory investigations, 400 optically stimulated luminescence (OSL) ages and more than 100 depositional records in the Chinese deserts and sand fields were obtained; on the basis of these data, we reconstruct spatial distributions of the deserts and sand fields during the LGM and HO. Our results show that the sand fields of Mu Us, Hunshandake, Horqin and Hulun Buir in northern and northeastern China had expanded 25%, 37%, 38% and 270%, respectively, during the LGM; the sand fields of Gonghe in the northeastern Qinghai-Tibetan Plateau had expanded 20%, and the deserts of Badain Jaran, Tengger in central northern China had expanded 39% and 29% separately during the LGM; the deserts of Taklimakan, Gurbantünggüt and Kumtag in northwestern China had expanded 10%-20% respectively, compared to their modern areas. On the other hand, all of the sand fields were nearly completely covered by vegetation during the HO; the deserts in northwestern and central northern China were reduced by around 5%-20% in area during this time. Lakes in this arid region were probably expanded during the HO but this conclusion needs more investigation. Compared with the geological distributions of deserts and sand fields, human activity has clearly changed (expanded) the area of active sand dunes at the present time. Our observations show that environmental conditions of Chinese deserts and sand fields are controlled by regional climate together with human activity.LU HuaYu YI ShuangWen XU ZhiWei ZHOU YaLi ZENG Lin ZHU FangYing FENG Han DONG LiNa ZHUO HaiXin YU KaiFeng MASON Joseph WANG XiaoYong CHEN YingYong LU Qi WU Bo DONG ZhiBao QU JianJun WANG XunMing GUO ZhengTang 2013Chinese Science Bulletin2013,58,23:40

18Cytokine-induced killer (ClK) cells:from basic research to clinical translation显示文摘The accumulation of basic researches and clinical studies related to cytokine-induced killer(CIK) cells has confirmed their safety and feasibility in treating malignant diseases.This review summarizes the available published literature related to the biological characteristics and clinical applications of CIK cells in recent years.A number of clinical trials with CIK cells have been implemented during the progressive phases of cancer,presenting potential widespread applications of CIK cells for the future.Furthermore,this review briefly compares clinical applications of CIK cells with those of other adoptive immunotherapeutic cells.However,at present,there are no uniform criteria or large-scale preparations of CIK cells.The overall clinical response is difficult to evaluate because of the use of autologous CIK cells.Based on these observations,several suggestions regarding uniform criteria and universal sources for CIK cell preparations and the use of CIK cells either combined with chemotherapy or alone as a primary strategy are briefly proposed in this review.Large-scale,controlled,grouped,and multi-center clinical trials on CIK cell-based immunotherapy should be conducted under strict supervision.These interventions might help to improve future clinical applications and increase the clinical curative effects of CIK cells for a broad range of malignancies in the future.Yelei Guo Weidong Han 2015Chinese Journal of Cancer2015,34,3:29
19Feeding of Riptortus pedestris on soybean plants, the primary cause of soybean staygreen syndrome in the Huang-Huai-Hai river basin显示文摘Staygreen syndrome or Zhengqing in soybean has recently become a major issue for Chinese growers in the Huang-Huai-Hai river basin.Although previous studies revealed that staygreen can be induced when pods/seeds are damaged, it is unknown whether virus infection or insect infestation causes staygreen.To determine whether viral infection causes staygreen, a survey of soybean staygreen incidence in the Huang-Huai-Hai river basin was conducted in 2016 and 2017.Diseased samples were collected and analyzed using DAS-ELISA for Soybean mosaic virus, Watermelon mosaic virus, Bean pod mottle virus, Cucumber mosaic virus, and Bean common mosaic virus.The survey showed that the severity of soybean staygreen syndrome was most prevalent in Beijing, Henan, Shaanxi, and some parts of Shandong provinces, with yield losses from 0 to nearly 100%, but only a small fraction of samples were positive for the tested viruses.A field cage experiment and an insecticide treatment field trial were conducted to determine the contribution of the bean bug, Riptortus pedestris, to staygreen incidence.The field cage experiment showed that R.pedestris treatment resulted in shorter plants, more empty pods, increased numbers of abnormal seeds, and decreased yields.The field experiment showed that there were fewer R.pedestris and less soybean staygreen incidence in fields treated with insecticide than in untreated control fields.Together, these results suggest that R.pedestris infestation rather than virus infection induces staygreen syndrome and that growers in this region can mitigate staygreen syndrome via bean bug control.Kai Li Xinxin Zhang Jianqiu Guo Hannah Penn Tingting Wu Lin Li Hong Jiang Lidan Chang Cunxiang Wu Tianfu Han 2019The Crop Journal2019,7,3:30
20The regulatory role of AT 1 receptor on activated HSCs in hepat,c fibrogenesis,effects of RAS inhibitors on hepatic fibrosis induced by CCl_4显示文摘AIM To assess the effect of ACE inhibitor andAng Ⅱ type Ⅰ(AT1)receptor antagonist inpreventing hepatic fibrosis caused by CCl4administration in rats;to investigate whether ornot there are expression of AT 1 receptors onhepatic stellate cells;and to observe the effectof Ang Ⅱ on proliferation and ECM synthesis ofcultured HSCs.METHODS Studies were conducted in maleSprague-Dawley rats.Except for thehepatofibrotic model group and the controlgroup,in three treated groups,either enalapril(5 mg/kg),or Iosartan(10 mg/kg),or enalapril+Iosartan were given to the fibrotic rats bydaily gavage,and saline vehicle was given tomodel and normal control rats.After 6 weeks,liver fibrosis was assessed directly by hepaticmorphometric analysis,which has beenconsidered the gold standard for thequantification of fibrosis.The expressions of AT1 receptors and(α-mooth muscle actin,α-SMA)in liver tissue or isolated hepatic stellate cells(HSCs)were detected by immunohistochemicaltechniques.The effect of Ang Ⅱ on HSCproliferation was determined by MTT method.Effect of Ang Ⅱ on collagen synthesis of HSCswas determined by 3H-proline incorporation.RESULTS Contrasted to the fibrosis in rats ofthe model group,groups of rats treated with either enalapril or Iosartan,or a combination oftwo drugs showed a limited expansion of theinterstitium(4.23±3.70 vs 11.22±4.79,P<0.05),but no difference was observedamong three treated groups(5.38±3.43,4.96±2.96,4.23±2.70,P>0.05).Expression of AT 1receptors was found in fibrotic interstitium offibrotic rats,whereas in normal control rats theywere limited to vasculature only to a very slightdegree.AT 1 receptors were also expressed onactivated HSCs in the culture.At concentrationsfrom 10-9to 10-5mol/L,Ang Ⅱ stimulated HSCproliferation in culture in a dose-dependentmanner.Increasing Ang Ⅱ concentrationsproduced corresponding increases in 3H-prolineincorporation.Differences among groups were significant.CONCLUSION Angiotensin-converting enzyme inhibitors and AT I blocker may slow the progression of hepatic fibrosis; activated HSCs express AT 1 receptors, and Ang Ⅱ can stimulate the proliferation and collagen synthesis of HSCs in a dose-dependent manner; and activation of RAS may be related to hepatic fibrogenesis induced by CCI4.Hong Shan Wei Han Ming Lu Ding Guo Li Yu Tao Zhan Zhi Rong Wang Xin Huang Ji Lin Cheng Qin Fang Xu Department of Gastroenterology,Xinhua Hospital,Shanghai Second Medical University,Shanghai 200092,China 2000World Journal of Gastroenterology2000,6,6:27
