1Towards 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

7Efficacy and safety of Xinfeng capsule in patients with rheumatoid arthritis:a multi-center parallel-group double-blind randomized controlled trial显示文摘OBJECTIVE:To evaluate the efficacy and safety of Xinfeng capsule in patients suffering rheumatoid arthritis(RA).METHODS:A multi-center parallel-group designed,double-blind,randomized,controlled trial was conducted.Totally 304 RA patients were assigned to two groups:one group was administered Xinfeng capsule(XFC) plus the placebo of leflunomide and the other given leflunomide(LEF) plus the placebo of XFC for twelve weeks.The clinical and laboratory parameters were compared at baseline and fourth,eighth,and twelfth weeks.RESULTS:After twelve-week treatment,patients in two groups all showed some trend of effectiveness when compared in terms of American Rheumatism Association(ACR) recommended 20%,50%,70%improvement criteria,but it was insignificant.The validity in ameliorate modified disease activity score(DAS28) and laboratory indexes as erythrocyte sedimentation rate(ESR),C-reactive protein(CRP),rheumatoid factor(RF) were also found no difference.The score of health assessment questionnaire(HAQ),self-rating anxiety scale(SAS),self-rating depression scale(SDS) and quality of life questionnaire with rheumatoid arthritis(RAQOL)both lower than the first week and the changes showed no difference.However,the score of SDS dropped more in XFC group than in the other.A total of 147 adverse reaction cases were reported,which shows no difference between the two groups.The most common adverse reactions were hepatic impairment,anemia,leukocytopenia,epigastric discomfort and phalacrosis.CONCLUSION:XFC demonstrated better improvement in the scores of SDS and compared with those of LEF group.Liu Jian Wang Yuan Huang Chuanbing Xu Jianhua Li Zhijun Xu Liang He Liyun Sun Yue Wang Yali Xu Shengqian Zhao Ping Mao Tongjun Tan Bin Zhu Fubing Zhang Pingheng Fang Li 2015Journal of Traditional Chinese Medicine2015,35,5:27
8EW-trending uplifts along the southern side of the central segment of the Altyn Tagh Fault, NW China: Insight into the rising mechanism of the Altyn Mountain during the Cenozoic显示文摘The Altyn Tagh Fault and the Altyn Mountain define respectively the tectonic and geographical northern edges of the Tibetan Plateau, and figure prominently in the growth and rising mechanism of the plateau. The rhombus-shaped Altyn Mountain has long been thought to have an intimate relation with the Altyn Tagh Fault; however, its formation mechanism remains unclear and debatable. In this paper, we focus on the EW-trending uplifts in the Altyn Mountain, and investigated three Cenozoic sedimentary sections in the vicinity of the EW-trending uplifts located along the southern side of the central segment of the Altyn Tagh Fault. Magnetostratigraphy and pollen analysis were used to constrain ages of the sediments. Clast composition of conglomerate and paleocurrents obtained from clast imbrications were applied to determine the provenance. We also established a geological section parallel to the Altyn Tagh Fault on sedimentary facies across the northwestern Qaidam Basin. The results indicate that these en-echelon EW-trending uplifts formed as early as ca. 36 Ma and were preferred to be under the control of basal shear of the Altyn Tagh Fault in the middle-lower crust, symbolizing the early uplift of the Altyn Mountain during the Cenozoic. Left-slip along the Altyn Tagh Fault occurring during the Miocene and afterwards displaced and altered these uplifts, shaping the Altyn Mountain to its present fabric.WU Lei XIAO AnCheng WANG LiQun MAO LiGuang WANG Liang DONG YouPu XU Bo 2012Science China Earth Sciences2012,55,6:21
9Current status of diagnosis and treatment of bladder cancer in China-Analyses of Chinese Bladder Cancer Consortium database显示文摘Objective:To investigate current status of diagnosis and treatment of bladder cancer in China.Methods:A database was generated by Chinese Bladder Cancer Consortium(CBCC).From January 2007 to December 2012,14,260 cases from 44 CBCC centers were included.Data of diagnosis,treatment and pathology were collected.Results:The average age was 63.5 year-old and most patients were male(84.3%).The most common histologic types were urothelial carcinoma(91.4%),adenocarcinoma(1.8%),and squamous carcinoma(1.9%).According to 1973 and 2004 WHO grading system,42.0%,41.0%,and 17.0% of patients were grade 1,2,and 3,and 16.0%,48.7%,and 35.3% of patients were papillary urothelial neoplasms of low malignant potential,low,and high grade,respectively.Non-muscle invasive bladder cancer(NMIBC)and muscle invasive bladder cancer(MIBC)were 25.2% and 74.1%,respectively(0.8% not clear).Carcinoma in situ was only 2.4%.Most patients were diagnosed by white-light cystoscopy with biopsy(74.3%).Fluorescence and narrow band imaging cystoscopy had additional detection rate of 1.0% and 4.0%,respectively.Diagnostic transurethral resection(TUR)provided detection rate of 16.9%.Most NMIBCs were treated with TUR(89.2%).After initial TUR,2.6%accepted second TUR,and 45.7%,69.9%,and 58.7% accepted immediate,induced,and maintenance chemotherapy instillation,respectively.Most MIBCs were treated with radical cystectomy(RC,59.7%).Laparoscopic RCs were 35.1%,while open RC 63.4%.Extended and standard pelvic lymph node dissection were 7% and 66%,respectively.Three most common urinary diversions were orthotopic neobladder(44%),ileal conduit(31%),and ureterocutaneostomy(23%).Only 2.3% of patients accepted neo-adjuvant chemotherapy and only 18%of T3 and T4 patients accepted adjuvant chemotherapy.Conclusion:Disease characteristics are similar to international reports,while differences of diagnosis and treatment exist.This study can provide evidences for revisions of the guideline on bladder cancer in China.Kaiwen Li Tianxin Lin Wei Xue Xin Mu Enci Xu Xu Yang Fubao Chen Guangyong Li Lulin Ma Guoliang Wang Chaozhao Liang Haoqiang Shi Ming Li Mao Tang Xueyi Xue Yisong Lv Yaoliang Deng Chengyang Li Zhiwen Chen Xiaozhou Zhou Fengshuo Jin Xudong Liu Jinxin Wei Lei Shi Xin Gou Weiyang He Liqun Zhou Lin Cai Baiye Jin Guanghou Fu Xiangbo Kong Hongyan Sun Ye Tian Lang Feng Tiejun Pan Yiyi Wu Dongwen Wang Hailong Hao Benkang Shi Yaofeng Zhu Qiang Wei Ping Han Changli Wu Dawei Tian Zhangqun Ye Zheng Liu Zhiping Wang Junqiang Tian Lin Qi Minfeng Chen Wei Li Jinchun Qi Gongxian Wang Longlong Fu Zhaolin Sun Guangheng Luo Zhoujun Shen Zhaowei Zhu Jinchun Xing Zhun Wu Dong Wei Xin Chen Yanqun Na Hongfeng Guo Chunxi Wang Zhihua Lu Chuize Kong Yang Liu Jin Yang Jianyun Hu Xin Gao Jielin Li Changjun Yin Pu Li Shan Chen Zhen Du Jiongming Li Yongji Yan Xu Zhang Shuang Huang Fangjian Zhou Zhiling Zhang Yinghao Sun Shuxiong Zeng Song Cen Jiaquan Zhou Hanzhong Li Jin Wen Jian Huang 2015Asian Journal of Urology2015,2,2:21
10Effects of plant species coexistence on soil enzyme activities and soil microbial community structure under Cd and Pb combined pollution显示文摘The relationship between plant species coexistence and soil microbial communities under heavy metal pollution has attracted much attention in ecology.However,whether plant species coexistence could offset the impacts of heavy metal combined pollution on soil microbial community structure and soil enzymes activities is not well studied.The modified ecological dose model and PCR-RAPD method were used to assess the effects of two plant species coexistence on soil microbial community and enzymes activities subjected to Cd and Pb combined stress.The results indicated that monoculture and mixed culture would increased microbe populations under Cd and Pb combined stress,and the order of sensitivity of microbial community responding to heavy metal stress was:actinomycetes > bacteria > fungi.The respirations were significantly higher in planted soil than that in unplanted soil.The plant species coexistence could enhance soil enzyme activities under Cd and Pb combined.Furthermore,planted soil would be helpful to enhance soil genetic polymorphisms,but Cd and Pb pollution would cause a decrease on soil genetic polymorphisms.Mixed culture would increase the ecological dose 50%(ED50) values,and the ED50 values for soil enzyme activities decreased with increasing culture time.The dehydrogenase was most sensitive to metal addition and easily loses activity under low dose of heavy metal.However,it was difficult to fully inhibit the phoshpatase activity,and urease responded similarly with phosphatase.Yang Gao Pei Zhou Liang Mao Yueer Zhi Chunhua Zhang Wanjun Shi 2010Journal of Environmental Sciences2010,22,7:19
11COVID-19 Outbreak Caused by Contaminated Packaging of Imported Cold-Chain Products—Liaoning Province,China,July 2020显示文摘Summary What is known about this topic?Few major outbreaks of coronavirus disease 2019(COVID-19)have occurred in China after major nonpharmaceutical interventions and vaccines have been deployed and implemented.However,sporadic outbreaks that had high possibility to be linked to cold chain products were reported in several cities of China..What is added by this report?In July 2020,a COVID-19 outbreak occurred in Dalian,China.The investigations of this outbreak strongly suggested that the infection source was from COVID-19 virus-contaminated packaging of frozen seafood during inbound unloading personnel contact.What are the implications for public health practice?Virus contaminated paper surfaces could maintain infectivity for at least 17–24 days at-25℃.Exposure to COVID-19 virus-contaminated surfaces is a potential route for introducing the virus to a susceptible population.Countries with no domestic transmission of COVID-19 should consider introducing prevention strategies for both inbound travellers and imported goods.Several measures to prevent the introduction of the virus via cold-chain goods can be implemented.Huilai Ma1 Jianqun Zhang Ji Wang Ying Qin Cao Chen Yang Song Liang Wang Jun Meng Lingling Mao Fengqin Li Ning Li Jian Cai Yong Zhang Dayan Wang Yunting Xia Hong Wang Shaofeng Jiang Xiang Zhao Peihua Niu Wenjie Tan Tao Ma Yecheng Yao Naiying Mao Zhen Zhu Tianjiao Ji Qian Yang Baoying Huang Li Zhao Jianxing Yu Li Bai Shuangli Zhu Dongyan Wang Yan Zhang Yingwei Sun Mingchun Luan Yanhai Wang Haibo Sun Shihong Yang Zhijian Bo Xiang Ren Zhongjie Li George Fu Gao Wei Yao Wenqing Yao Zijian Feng Wenbo Xu 2021China CDC weekly2021,3,21:16
12Plant diversity reduces the effect of multiple heavy metal pollution on soil enzyme activities and microbial community structure显示文摘It is unclear whether certain plant species and plant diversity could reduce the impacts of multiple heavy metal pollution on soil microbial structure and soil enzyme activities. Random amplified polymorphic DNA (RAPD) was used to analyze the genetic diversity and microbial similarity in planted and unplanted soil under combined cadmium (Cd) and lead (Pb) pollution. A metal hyper- accumulator, Brassica juncea, and a common plant, Festuca arundinacea Schreb, were used in this research. The results showed that microorganism quantity in planted soil significantly increased, compared with that in unplanted soil with Cd and Pb pollution. The order of microbial community sensitivity in response to Cd and Pb stress was as follows: actinomycetes 〉 bacteria 〉 fungi. Respiration, phosphatase, urease and dehydrogenase activity were significantly inhibited due to Cd and Pb stress. Compared with unplanted soil, planted soils have frequently been reported to have higher rates of microbial activity due to the presence of additional surfaces for microbial colonization and organic compounds released by the plant roots. Two coexisting plants could increase microbe population and the activity of phosphatases, dehydrogenases and, in particular, ureases. Soil enzyme activity was higher in B. juncea phytoremediated soil than in F. arundinacea planted soil in this study. Heavy metal pollution decreased the richness of the soil microbial community, but plant diversity increased DNA sequence diversity and maintained DNA sequence diversity at highlevels. The genetic polymorphism under heavy metal stress was higher in B. juncea phytoremediated soil than in F. arundinacea planted soil.Yang GAO Chiyuan MIAO Jun XIA Liang MAO Yafeng WANG Pei ZHOU 2012Frontiers of Environmental Science & Engineering2012,6,2:14

14Roux-en-Y gastric bypass for Chinese type 2 diabetes mellitus patients with a BMI,28kg/m^2:a multi-institutional study显示文摘Roux-en-Y gastric bypass surgery(RYGB) has been demonstrated to be successful for treating type-II diabetes2mellitus(T2DM) patients with a body mass index(BMI),30 kg/m,but reports of RYGB for T2 DM patients with22 a BMI,28 kg/mare lacking.T2 DM patients with a BMI,28 kg/mwere prospectively recruited to participate in this study in four hospitals.The endpoint was T2 DM remission(defined by fasting blood glucose(FBG) level,110 mg/d L and hemoglobin(Hb)A1c level,6.0% at 12 months postoperatively).Predictors of remission were investigated by univariate and multivariate analyses.Eighty-six patients were assessed.Eighty-five patients underwent RYGB,with one conversion to open surgery.We compared the values of various variables before and after2 surgery.The mean BMI decreased from 24.68±2.12 to 21.72±2.43 kg/m(P,0.001).Fifty-eight(67.4%) patients were not treated by drugs or insulin after surgery,and 20 patients(23.3%) had complete remission of T2 DM at12 months after surgery with an acceptable number of complications.The mean Hb A1 c level in the remission group was significantly lower than that in the non-remission group.Patients with a higher weight,lower Hb A1 c level,higher C-peptide level,and higher FBG level were more likely to have T2 DM remission in multivariate2 analyses.In conclusion,RYGB was effective and safe for treating T2 DM patients with a BMI,28 kg/m.Complete remission can be predicted by cases having a higher weight,lower Hb A1 c level,higher C-peptide level,and higher FBG level.Hui Liang Wei Guan Yanling Yang Zhongqi Mao Yijun Mei Huan Liu Yi Miao 2015The Journal of Biomedical Research2015,29,2:13

16Trabecular-like Ti-6Al-4V scaffolds for orthopedic: fabrication by selective laser melting and in vitro biocompatibility显示文摘Porous metal scaffolds play an important role in the orthopedic field, due to their wide applications in prostheses implantation. Some previous studies showed that the scaffolds with trabecular bone structure reconstructed via computed tomography had satisfactory biocompatibility. However, the reverse modeling scaffolds were inflexible for customized design. Therefore, a top-down designing biomimetic bone scaffold with favorable mechanical performances and cytocompatibility is urgently demanded for orthopedic implants. An emerging additive manufacturing technique, selective laser melting, was employed to fabricate the trabecular-like porous Ti-6Al-4 V scaffolds with varying irregularities(0.05-0.5) and porosities(48.83%–74.28%) designed through a novel Voronoi-Tessellation based method. Micro-computed tomography and scanning electron microscopy were used to characterize the scaffolds’ morphology.Quasi-static compression tests were performed to evaluate the scaffolds’ mechanical properties. The MG63 cells culture in vitro experiments, including adhesion, proliferation, and differentiation, were conducted to study the cytocompatibility of scaffolds. Compressive tests of scaffolds revealed an apparent elastic modulus range of 1.93–5.24 GPa and an ultimate strength ranging within 44.9–237.5 MPa, which were influenced by irregularity and porosity, and improved by heat treatment. Furthermore, the in vitro assay suggested that the original surface of the SLM-fabricated scaffolds was favorable for osteoblasts adhesion and migration because of micro scale pores and ravines. The trabecular-like porous scaffolds with full irregularity and higher porosity exhibited enhanced cells proliferation and osteoblast differentiation at earlier time, due to their preferable combination of small and large pores with various shapes. This study suggested that selective laser melting-derived Ti-6Al-4 V scaffold with the trabecular-like porous structure designed through Voronoi-Tessellation method, favorable mechanical performance, and good cytocompatibility was a potential biomaterial for orthopedic implants.Huixin Liang Youwen Yang Deqiao Xie Lan Li Ning Mao Changjiang Wang Zongjun Tian Qing jiang Lida Shen 2019Journal of Materials Science & Technology2019,35,7:12

18Pure Mucinous Carcinoma of the Breast:a Clinicopathologic Analysis with 56 Patients显示文摘Objective To assess recent trends and prognostic features in the treatment of pure mucinous carcinoma(PMC) of the breast.Methods Fifty-six patients diagnosed with PMC of the breast in our hospital from December 1982 to June 2008 were included.We evaluated the general information and tumor characteristics of the patients,examined the relationship between these factors and prognosis.Fisher's exact test was applied to analyze tumor characteristics.Results The mean age of the patients was 53.7 years.The majority of the patients presented with early stage disease.Tumor size was found not a significant prognostic factor in this study.Mean follow-up period was 39 months and no breast cancer-related deaths were identified in the patient cohort.Conclusions PMC of the breast has a favorable prognosis.Tumor size does not appear to significantly impact survival.Li Peng Qiang Sun Zhi-yong Liang Yi-dong Zhou Feng Mao Jing-hong Guan 2010Chinese Medical Sciences Journal2010,25,2:11
19Aerodynamic Interactions Between Contralateral Wings and Between Wings and Body of a Model Insect at Hovering and Small Speed Motions显示文摘In this paper, we study the aerodynamic interactions between the contralateral wings and between the body and wings of a model insect, when the insect is hovering and has various translational and rotational motions, using the method numerically solving the Navier-Stokes equations over moving overset grids. The aerodynamic interactional effects are identified by compar-ing the results of a complete model insect, the corresponding wing pair, single wing and body without the wings. Horizontal, vertical and lateral translations and roll, pitch and yaw rotations at small speeds are considered. The results indicate that for the motions considered, both the interaction between the contralateral wings and the interaction between the body and wings are weak. The changes in the forces and moments of a wing due to the contralateral wing interaction, of the wings due to the pres-ence of the body, and of the body due to the presence of the wings are generally less than 4.5%. Results show that aerodynamic forces of wings and body can be measured or computed separately in the analysis of flight stability and control of hovering in-sects.LIANG Bin SUN Mao 2011Chinese Journal of Aeronautics2011,24,4:11
