| 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 | Association of H.pylori infection with gastric carcinoma:a Meta analysis显示文摘AIM: To follow the principles of evidence based medicine to reach the integrated results of these studies.METHODS: Twenty-one papers of case-control studies were selected, including 11 on gastric cancer, 7 on precancerous lesion of stomach and 3 on lymphoma of stomach: Meta analysis was used to sum up the odds ratios (OR) of these studies.RESULTS: H. Pylori vsgastric cancer (intestinal and diffuse type): the odds ratio from the fixed effect model is 3.0016(95% Cl 2.4197-3.7234, P < 0.001 ). H. Pylori vs precancerous lesion of stomach: a random effect model was used to calculate the summary odds ratio and its value is 2.5635 (95% Cl: 1.8477-3.5566, P < 0.01). H. Pylori vs lymphoma of stomach: though the quantity of literature is too small to make Meta analysis, the data of these 3 studies show that lymphoma of stomach is highly associated with H. Pylori infections.CONCLUSION: Since it had been revealed that H. Pylori infection pre-exists in gastric carcinoma and precancerous lesions, the results of Meta analysis present a strong evidence to support the conclusion that H. Pylori infection is a risk factor for gastric carcinoma. | Fu-Bo Xue~1 Yong-Yong Xu~1 Yi Wan~1 Bo-Rong Pan~2 Jun Ren~2 Dai-Ming Fan~3 1 Department of Health Statistics,Department of2 Oncology3 Gastroenterology of XiJing Hospital,the Fourth Military Medical University,Xi’an 710032,Shaanxi Province,China | 2001 | World Journal of Gastroenterology2001，7，6： | 66 |
| 3 | Epidemiology and gene markers of ulcerative colitis in the Chinese显示文摘Inflammatory bowel disease(IBD)includes two similar yet distinct conditions called ulcerative colitis(UC)and Crohn's disease(CD).These diseases affect the digestive system and cause the inflammation of intestinal tissue,form sores and bleed easily.Most children with IBD are diagnosed in late childhood and adolescence.However,both UC and CD have been reported as early as in infancy.Most information pertaining to the epidemiology of IBD is based upon adult studies.Symptoms include abdominal pain,cramping,fatigue and diarrhea.Genetic factors play a significant role in determining IBD susceptibility.Epidemiological data support a genetic contribution to the pathogenesis of IBD.Recently,numerous new genes have been identified as being involved in the genetic susceptibility to IBD:TNF-308A,CARD15(NOD2),MIF-173,N-acetyltransferase 2(NAT2),NKG2D(natural killer cell 2D),STAT6(signal transducer and activator of transcription 6),CTLA-4(cytotoxic T lymphocyte antigen-4),MICA-MICB(major histocompatibility complex A and B),HLA-DRB1,HLA class-,IL-18,IL-4,MICA-A5,CD14,TLR4,Fas-670,p53 and NF-κB.The characterization of these novel genes has the potential to identify therapeutic agents and aid clinical assessment of phenotype and prognosis in patients with IBD(UC and CD). | Jun Yun Chang-Tai Xu Bo-Rong Pan | 2009 | World Journal of Gastroenterology2009，15，7： | 35 |

| 5 | Environmental connections of novel avian-origin H7N9 influenza virus infection and virus adaptation to the human显示文摘A novel H7N9 influenza A virus has been discovered as the causative identity of the emerging acute respiratory infection cases in Shanghai,China.This virus has also been identified in cases of infection in the neighboring area Hangzhou City in Zhejiang Province.In this study,epidemiologic,clinical,and virological data from three patients in Hangzhou who were confirmed to be infected by the novel H7N9 influenza A virus were collected and analyzed.Human respiratory specimens and chicken feces from a contacted free market were tested for influenza virus by real-time reverse transcription PCR(RT-PCR) and sequencing.The clinical features of the three cases were similar featured with high fever and severe respiratory symptoms;however,only one of the patients died.A certain degree of diversity was observed among the three Hangzhou viruses sequenced from human samples compared with other reported H7N9 influenza A viruses.The sequences of the novel avian-origin H7N9 influenza viruses from Hangzhou City contained important amino acid substitutions related to human adaptation.One of the Hangzhou viruses had gained a novel amino acid substitution(Q226I) in the receptor binding region of hemagglutinin.More importantly,the virus sequenced from the chicken feces had a 627E substitution in the PB2 protein instead of the mammalian-adapted 627K substitution that was found in the PB2 proteins from the Hangzhou viruses from the three patients.Therefore,the newly-emerging H7N9 virus might be under adaptation pressure that will help it 'jump' from avian to human hosts.The significance of these substitutions needs further exploration,with both laboratory experiments and extensive field surveillance. | LI Jun YU XinFen PU XiaoYing XIE Li SUN YongXiang XIAO HaiXia WANG FenJuan DIN Hua WU Ying LIU Di ZHAO GuoQiu LIU Jun PAN JingCao | 2013 | Science China(Life Sciences)2013，56，6： | 32 |

| 8 | Magnetic resonance diffusion tensor imaging following major ozonated autohemotherapy for treatment of acute cerebral infarction显示文摘Major ozonated autohemotherapy has been shown to promote recovery of upper limb motor function in patients with acute cerebral infarction,but whether major ozonated autohemotherapy affects remote injury remains poorly understood.Here,we assumed that major ozonated autohemotherapy contributes to recovery of clinical function,possibly by reducing remote injury after acute cerebral infarction.Sixty acute cerebral infarction patients aged 30–80 years were equally and randomly allocated to ozone treatment and control groups.Patients in the ozone treatment group received medical treatment and major ozonated autohemotherapy(47 mg/L,100 m L ozone) for 10 ± 2 days.Patients in the control group received medical treatment only.National Institutes of Health Stroke Scale score,modified Rankin scale score,and reduced degree of fractional anisotropy values of brain magnetic resonance diffusion tensor imaging were remarkably decreased,brain function improved,clinical efficiency significantly increased,and no obvious adverse reactions detected in the ozone treatment group compared with the control group.These findings suggest that major ozonated autohemotherapy promotes recovery of neurological function in acute cerebral infarction patients by reducing remote injury,and additionally,exhibits high safety. | Xiao-na Wu Tao Zhang Jun Wang Xiao-yan Liu Zhen-sheng Li Wei Xiang Wei-qing Du Hong-jun Yang Tie-gen Xiong Wen-ting Deng Kai-run Peng Su-yue Pan | 2016 | Neural Regeneration Research2016，11，7： | 32 |
| 9 | Caspase-11/4 and gasdermin D-mediated pyroptosis contributes to podocyte injury in mouse diabetic nephropathy显示文摘Diabetic nephropathy(DN)is characterized by sterile inflammation with continuous injury and loss of renal inherent parenchyma cells.Podocyte is an essential early injury target in DN.The injury and loss of podocytes are closely associated with proteinuria,the early symptom of renal injury in DN.However,the exact mechanism for podocyte injury and death in DN remains ambiguous.In this study we investigated whether pyroptosis,a newly discovered cell death pathway was involved in DN.Diabetic mice were generated by high-fat diet/STZ injections.We showed that the expression levels of caspase-11 and cleavage of gasdermin D(GSDMD-N)in podocytes were significantly elevated,accompanied by reduced expression of podocyte makers nephrin and podocin,loss and fusion in podocyte foot processes,increased inflammatory cytokines NF-κB,IL-1β,and IL-18,macrophage infiltration,glomerular matrix expansion and increased urinary albumin to creatinine ratio(UACR).All these changes in diabetic mice were blunted by knockout of caspase-11 or GSDMD.Cultured human and mouse podocytes were treated with high glucose(30 mM),which significantly increased the expression levels of caspase-11 or caspase-4(the homolog of caspase-11 in human),GSDMD-N,NF-κB,IL-1β,and IL-18,and decreased the expression of nephrin and podocin.Either caspase-4 or GSDMD knockdown by siRNA significantly blunted these changes.In summary,our results demonstrate that caspase-11/4 and GSDMD-mediated pyroptosis is activated and involved in podocyte loss under hyperglycemia condition and the development of DN. | Qian Cheng Jing Pan Zhuan-li Zhou Fan Yin Hong-yan Xie Pan-pan Chen Jing-yao Li Pei-qing Zheng Li Zhou Wei Zhang Jun Liu Li-min Lu | 2021 | Acta Pharmacologica Sinica2021，42，6： | 33 |
| 10 | 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 |
| 11 | Isolation and Identification of Cancer Stem-Like Cells from Murine Melanoma Cell Lines显示文摘In current study,cancer stem-like cells in the murine melanoma B16F10 cells were investigated.CD phenotypes of the B16F10 cells were analyzed by flow cytometry,and the specific CD phenotype cells from the B16F10 cells were isolated by MACS.Then we used colony formation assay in soft agar media,the cell growth assay in serum-free culture media as well as the tumorigenicity investigation of the specific CD phenotype cells in C57BL/6 mice, respectively,to identify cancer stem-like cells in the B16F10 cells.The results showed that the B16F10 cells could form spherical clones in serum-free culture media,and the rate of clonegenesis of CD133 + ,CD44 + and CD44 + CD133 + cells was higher than that of CD133 - ,CD44 - and CD44 + CD133 - cells in soft agar media,respectively. The tumorigenic potential of CD133 + ,CD44 + ,CD44 + CD133 + cells and CD44 + CD133 + CD24 + cells was stronger than that of CD133 - ,CD44 - ,CD44 + CD133 - cells and CD44 + CD133 + CD24 - cells in mice,respectively.In conclusion,the CD44 + CD133 + CD24 + cells have some biological properties of cancer stem-like cells or are highly similar to the characteristics of cancer stem cells(CSC).These results provide an important method for identifying cancer stem-like cells in B16F10 cells and for further cancer target therapy. | Jun Dou Meng Pan Ping Wen Yating Li Quan Tang Lili Chu Fengshu Zhao Chuilian Jiang Weihua Hu Kai Hu Ning Gu | 2007 | Cellular & Molecular Immunology2007，4，6： | 25 |
| 12 | Single-photon computational 3D imaging at 45 km显示文摘Single-photon light detection and ranging(lidar)offers single-photon sensitivity and picosecond timing resolution,which is desirable for high-precision three-dimensional(3 D)imaging over long distances.Despite important progress,further extending the imaging range presents enormous challenges because only a few echo photons return and are mixed with strong noise.Here,we tackled these challenges by constructing a high-efficiency,low-noise coaxial single-photon lidar system and developing a long-range-tailored computational algorithm that provides high photon efficiency and good noise tolerance.Using this technique,we experimentally demonstrated active single-photon 3 D imaging at a distance of up to 45 km in an urban environment,with a low return-signal level of^1 photon per pixel.Our system is feasible for imaging at a few hundreds of kilometers by refining the setup,and thus represents a step towards low-power and high-resolution lidar over extra-long ranges. | ZHENG-PING LI XIN HUANG YUAN CAO BIN WANG YU-HUAI LI WEIJIE JIN CHAO YU JUN ZHANG QIANG ZHANG CHENG-ZHI PENG FEIHU XU AND JIAN-WEI PAN | 2020 | Photonics Research2020，8，9： | 24 |

| 14 | Efficacy and safety of gemcitabine-oxaliplatin combined with huachansu in patients with advanced gallbladder carcinoma显示文摘AIM: To evaluate the efficacy and safety of gemcitabine-oxaliplatin (GEMOX) combined with huachansu (cinobufagin) injection treatment in patients with locally advanced or metastatic gallbladder carcinoma (GBC), and to assess the quality of life (QOL) of such patients. METHODS: Twenty-fi ve patients with locally advanced or metastatic GBC were treated with intravenous gemcitabine (1000 mg/m2) over 30 min on days 1 and 8, 2 h infusion of oxaliplatin (120 mg/m2) on day 1, and 2-3 h infusion of huachansu (20 mL/m2) on days -3-11, every 3-4 wk. Treatment was continued until occurrence of unacceptable toxicity or disease progression. QOL of patients was assessed by the EORTC QLQ-C30 at baseline, at the end of the fi rst, third and sixth chemotherapy cycles, and 1 mo after the treatment. RESULTS: Among the 25 patients with a median age of 64 years (range 42-78 years), 23 were evaluable in the study. A total of 137 cycles of therapy were performed and the median cycle was 5 (range 1-8) per patient. Out of the 23 patients whose response couldbe evaluated, 8 partial responses (PR) were observed (34.8%), while 7 patients (30.4%) demonstrated a stable disease (SD). The disease control rate was 65.2%. Progression of cancer was observed in 8 (34.8%) patients. The median progression-free and overall survival time was 5.8 mo (95% CI: 4.5-7.1 mo) and 10.5 mo, respectively. The therapy was well tolerated, with moderate myelosuppression as the main toxicity. Anemia grade 2 was seen in 16.0%, neutropenia grade 3 in 8.0% and thrombocytopenia grade 3 in 24.0% of patients, respectively. Non-hematologic toxicity ranged from mild to moderate. No death occurred due to toxicity. The QOL of patients was improved after chemotherapy, and the scores of QOL were increased by 10 to 20 points. CONCLUSION: GEMOX combined with huachansu (cinobufagin) injection is well tolerated, effective, thus improving the QOL of patients with advanced GBC. | Tian-Jie Qin Xin-Han Zhao Jun Yun Ling-Xiao Zhang Zhi-Ping Ruan Bo-Rong Pan | 2008 | World Journal of Gastroenterology2008，14，33： | 22 |
| 15 | Accelerated Degradation Reliability Modeling and Test Data Statistical Analysis of Aerospace Electrical Connector显示文摘As few or no failures occur during accelerated life test,it is difficult to assess reliability for long-life products with traditional life tests.Reliability assessment using degradation data of product performance over time becomes a significant approach.Aerospace electrical connector is researched in this paper.Through the analysis of failure mechanism,the performance degradation law is obtained and the statistical model for degradation failure is set up;according to the research on statistical analysis methods for degradation data,accelerated life test theory and method for aerospace electrical connector based on performance degradation is proposed by improving time series analysis method,and the storage reliability is assessed for Y11X series of aerospace electrical connector with degradation data from accelerated degradation test.The result obtained is basically consistent with that obtained from accelerated life test based on failure data,and the two estimates of product's characteristic life only have a difference of 8.7%,but the test time shortens about a half.As a result,a systemic approach is proposed for reliability assessment of highly reliable and long-life aerospace product. | CHEN Wenhua LIU Juan GAO Liang PAN Jun ZHOU Shengjun | 2011 | Chinese Journal of Mechanical Engineering2011，24，6： | 22 |
| 16 | Secukinumab demonstrates high efficacy and a favorable safety profile over 52 weeks in Chinese patients with moderate to severe plaque psoriasis显示文摘Background:Psoriasis is a chronic inflammatory skin disease,affecting about 0.6%of the Chinese population.Many patients are not well controlled by conventional treatments,thus there is need for new treatment regimens.In this study,we assessed the efficacy and safety of secukinumab in Chinese patients with moderate to severe plaque psoriasis.Methods:This study was a 52-week,multicentre,randomized,double-blind,placebo-controlled,parallel-group,Phase 3 trial.A sub-population of study participants(≥18 years)of Chinese ethnicity were randomized to receive subcutaneous injections of 300 or 150 mg secukinumab,or placebo.The co-primary endpoints were psoriasis area severity index(PASI)75 and Investigator’s Global Assessment(IGA)0/1 at Week 12.Results:A total of 441 Chinese patients were enrolled in this study.Co-primary outcomes were achieved;300 and 150 mg secukinumab were superior to placebo as shown in the proportion of patients that achieved PASI 75(97.7%and 87.2%vs.3.7%,respectively;P<0.001),and IGA 0/1(82.3%and 69.7%vs.2.7%;P<0.001)at Week 12.Treatment efficacy was maintained until Week 52.There was no increase in overall adverse events with secukinumab relative to placebo throughout the 52-week period.Conclusion:Secukinumab is highly effective and well tolerated in Chinese patients with moderate to severe plaque psoriasis. | Lin Cai Jian-Zhong Zhang Xu Yao Jun Gu Quan-Zhong Liu Min Zheng Shi-Fa Zhang Jin-Hua Xu Cheng-Xin Li Hao Cheng Qing Guo Wei-Li Pan Shen-Qiu Li Ruo-Yu Li Zai-Pei Guo Zhi-Qi Song Shan-Shan Li Xiu-Qin Dong Linda Wang Rong Fu Pascaline Regnault Pascal Charef Ratal Mazur Manmath Patekar | 2020 | Chinese Medical Journal2020，，22： | 21 |
| 17 | Advances in InGaAs/InP single-photon detector systems for quantum communication显示文摘Single-photon detectors(SPDs)are the most sensitive instruments for light detection.In the near-infrared range,SPDs based on III–V compound semiconductor avalanche photodiodes have been extensively used during the past two decades for diverse applications due to their advantages in practicality including small size,low cost and easy operation.In the past decade,the rapid developments and increasing demands in quantum information science have served as key drivers to improve the device performance of single-photon avalanche diodes and to invent new avalanche quenching techniques.This Review aims to introduce the technology advances of InGaAs/InP single-photon detector systems in the telecom wavelengths and the relevant quantum communication applications,and particularly to highlight recent emerging techniques such as high-frequency gating at GHz rates and free-running operation using negative-feedback avalanche diodes.Future perspectives of both the devices and quenching techniques are summarized. | Jun Zhang Mark A Itzler Hugo Zbinden Jian-Wei Pan | 2015 | Light(Science & Applications)2015，4，1： | 21 |

| 19 | Synthesis of novel nanomaterials and their application in efficient removal of radionuclides显示文摘With the development of nuclear energy, large amounts of radionuclides are inevitably released into the natural environment. It is necessary to eliminate radionuclides from wastewater for the protection of environment. Nanomaterials have been considered as the potential candidates for the effective and selective removal of radionuclides from aqueous solutions under complicated conditions because of their high specific surface area, large amounts of binding sites, abundant functional groups, pore-size controllable and easily surface modification. This review mainly summarized the recent studies for the synthesis, fabrication and surface modification of novel nanomaterials and their applications in the efficient elimination and solidification of radionuclides,and discussed the interaction mechanisms from batch experiments, spectroscopy analysis and theoretical calculations. The sorption capacities with other materials, advantages and disadvantages of different nanomaterials are compared, and at last the perspective of the novel nanomaterials is summarized. | Xiangxue Wang Long Chen Lin Wang Qiaohui Fan Duoqiang Pan Jiaxing Li Fangting Chi Yi Xie Shujun Yu Chengliang Xiao Feng Luo Jun Wang Xiaolin Wang Changlun Chen Wangsuo Wu Weiqun Shi Shuao Wang Xiangke Wang | 2019 | Science China Chemistry2019，62，8： | 20 |
| 20 | Adsorption of Cr(Ⅲ) from acidic solutions by crop straw derived biochars显示文摘Cr(III) adsorption by biochars generated from peanut, soybean, canola and rice straws is investigated with batch methods. Adsorption of Cr(III) increased as pH rose from 2.5 to 5.0. Adsorption of Cr(III) led to peak position shifts in the FTIR-PAS spectra of the biochars and made zeta potential values less negative, suggesting the formation of surface complexes between Cr3+and functional groups on the biochars. The adsorption capacity of Cr(III) followed the order: peanut straw char > soybean straw char > canola straw char > rice straw char, which was consistent with the content of acidic functional groups on the biochars. The increase in Cr3+hydrolysis as the pH rose was one of the main reasons for the increased adsorption of Cr(III) by the biochars at higher pH values. Cr(III) can be adsorbed by the biochars through electrostatic attraction between negative surfaces and Cr3+, but the relative contribution of electrostatic adsorption was less than 5%. Therefore, Cr(III) was mainly adsorbed by the biochars through specific adsorption. The Langumir and Freundlich equations fitted the adsorption isotherms well and can therefore be used to describe the adsorption behavior of Cr(III) by the crop straw biochars. The crop straw biochars have great adsorption capacities for Cr(III) under acidic conditions and can be used as adsorbents to remove Cr(III) from acidic wastewaters. | Jingjian Pan Jun Jiang Renkou Xu | 2013 | Journal of Environmental Sciences2013，25，10： | 19 |
