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

3Transmission Dynamics of an Outbreak of the COVID-19 Delta Variant B.1.617.2——Guangdong Province,China,May-June 2021显示文摘On May 21,2021,a local case of coronavirus disease 2019(COVID-19)was confirmed in a 75-year-old woman(experienced onset of symptoms on May 18)in Liwan District,Guangzhou City,Guangdong Province,China.The number of infections has increased in the following 10 days and led to 5 generations of transmission.Meng Zhang Jianpeng Xiao Aiping Deng Yingtao Zhang Yali Zhuang Ting Hu Jiansen Li Hongwei Tu Bosheng Li Yan Zhou Jun Yuan Lei Luo Zimian Liang Youzhi Huang Guoqiang Ye Mingwei Cai Gongli Li Bo Yang Bin Xu Ximing Huang Yazun Cui Dongsheng Ren Yanping Zhang Min Kang Yan Li 2021China CDC weekly2021,3,27:51
4Distribution of Soil Organic Carbon Fractions Along the Altitudinal Gradient in Changbai Mountain,China显示文摘Understanding the responses of soil organic carbon(SOC) fractions to altitudinal gradient variation is important for understanding changes in the carbon balance of forest ecosystems.In our study the SOC and its fractions of readily oxidizable carbon(ROC),water-soluble carbon(WSC) and microbial biomass carbon(MBC) in the soil organic and mineral horizons were investigated for four typical forest types,including mixed coniferous broad-leaved forest(MCB),dark coniferous spruce-fir forest(DCSF),dark coniferous spruce forest(DCS),and Ermans birch forest(EB),along an altitudinal gradient in the Changbai Mountain Nature Reserve in Northeast China.The results showed that there was no obvious altitudinal pattern in the SOC.Similar variation trends of SOC with altitude were observed between the organic and mineral horizons.Significant differences in the contents of SOC,WSC,MBC and ROC were found among the four forest types and between horizons.The contents of ROC in the mineral horizon,WSC in the organic horizon and MBC in both horizons in the MCB and EB forests were significantly greater than those in either DCSF or DCS forest.The proportion of soil WSC to SOC was the lowest among the three main fractions.The contents of WSC,MBC and ROC were significantly correlated(P < 0.05) with SOC content.It can be concluded that vegetation types and climate were crucial factors in regulating the distribution of soil organic carbon fractions in Changbai Mountain.ZHANG Min ZHANG Xiao-Ke LIANG Wen-Ju JIANG Yong DAI Guan-Hua WANG Xu-Gao HAN Shi-Jie 2011Pedosphere2011,21,5:43
5Ganoderic acid hinders renal fibrosis via suppressing the TGF- β/Smad and MAPK signaling pathways显示文摘Renal fibrosis is considered as the pathway of almost all kinds of chronic kidney diseases(CKD)to the end stage of renal diseases(ESRD).Ganoderic acid(GA)is a group of lanostane triterpenes isolated from Ganoderma lucidum,which has shown a variety of pharmacological activities.In this study we investigated whether GA exerted antirenal fibrosis effect in a unilateral ureteral obstruction(UUO)mouse model.After UUO surgery,the mice were treated with GA(3.125,12.5,and 50 mg·kg^−1·d^−1,ip)for 7 or 14 days.Then the mice were sacrificed for collecting blood and kidneys.We showed that GA treatment dose-dependently attenuated UUO-induced tubular injury and renal fibrosis;GA(50 mg·kg^−1·d^−1)significantly ameliorated renal disfunction during fibrosis progression.We further revealed that GA treatment inhibited the extracellular matrix(ECM)deposition in the kidney by suppressing the expression of fibronectin,mainly through hindering the over activation of TGF-β/Smad signaling.On the other hand,GA treatment significantly decreased the expression of mesenchymal cell markers alpha-smooth muscle actin(α-SMA)and vimentin,and upregulated E-cadherin expression in the kidney,suggesting the suppression of tubular epithelial-mesenchymal transition(EMT)partially via inhibiting both TGF-β/Smad and MAPK(ERK,JNK,p38)signaling pathways.The inhibitory effects of GA on TGF-β/Smad and MAPK signaling pathways were confirmed in TGF-β1-stimulated HK-2 cell model.GA-A,a GA monomer,was identified as a potent inhibitor on renal fibrosis in vitro.These data demonstrate that GA or GA-A might be developed as a potential therapeutic agent in the treatment of renal fibrosis.Xiao-qiang Geng Ang Ma Jin-zhao He Liang Wang Ying-li Jia Guang-ying Shao Min Li Hong Zhou Shu-qian Lin Jian-hua Ran Bao-xue Yang 2020Acta Pharmacologica Sinica2020,41,5:43
6A novel integrated step-feed biofilm process for the treatment of decentralized domestic wastewater in rural areas of China显示文摘For wastewater treatment in rural areas, a novel three-stage step-feed wastewater treatment system, combined with a drop-aeration biofilm process, was tested in the laboratory to investigate its performance in removing suspended solids (SS), chemical oxygen demand (COD), NH4+-N, total nitrogen (TN), and total phosphorus (TP). The removal rates of SS, COD and NH4+-N were 90%, 80%, and 90% in efluent concentrations less than 10 mg/L, 50 mg/L and 8 mg/L, respectively. The TP removal rate was less satisfactory. The C/N ratio in the raw wastewater was often less than 3.5, and the removal efficiency of TN was therefore limited. A carbon-release batch experiment was carried out to measure the feasibility of enhancing denitrification at low influent C/N ratios. The result showed that the C/N could be over 9.0 in the supernatant. Polymerase chain reaction denaturing gradient gel electrophoresis technology was used to reveal the changes in the bacterial community during different stages of the integrated step-feed biofilm process. The results showed that banding patterns and the distribution of dominant bands for the same experimental period in different aerobic zones were similar. Phylogenetic analysis indicated that lanes 10, 11 and 12, which presented three aerobic zones at the same operation period, had the closest phylogenetic relationship among the lanes.Hanwen Liang, Min Gao, Junxin Liu, Yuansong Wei, Xuesong Guo Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences, Beijing 100085, China. 2010Journal of Environmental Sciences2010,22,3:28

9microRNAs, an active and versatile group in cancers显示文摘microRNAs (miRNAs) are a class of non-coding RNAs that function as endogenous triggers of the RNA interference pathway. Studies have shown that thousands of human protein-coding genes are regulated by miRNAs, indicating that miRNAs are master regulators of many important biological processes, such as cancer development. miRNAs frequently have deregulated expression in many types of human cancers, and play critical roles in tumorigenesis, which functions either as tumor suppressors or as oncogenes. Recent studies have shown that miRNAs are highly related with cancer progression, including initiating, growth, apoptosis, invasion, and metastasis. Furthermore, miRNAs are shown to be responsible for the cancer-related inflam- mation, anti-cancer drug resistance, and regulation of cancer stem cells. Therefore, miRNAs have generated great interest as a novel strategy in cancer diagnosis and therapy. Here we review the versatile roles of miRNAs in cancers and their potential applications for diagnosis, prognosis, and treatment as biomarkers.Jeffrey Liu Min Zheng Ya-ling Tang Xin-hua Liang Qin Yang 2011International Journal of Oral Science2011,3,4:23
10Charlson comorbidity index helps predict the risk of mortality for patients with type 2 diabetic nephropathy显示文摘研究目的:探讨Charlson合并症指数(CCI)对2型糖尿病肾病死亡率的预测作用。研究方法:建立2型糖尿病肾病研究队列,根据CCI评分将患者合并症的严重程度分为三度:轻度(CCI1–2分)、中度(CCI 3–4分)、重度(CCI≥5分)。将影响死亡率的因素及按CCI分层后的组间差异指标进行Logistic回归分析及方差分析(ANOVA)。Kaplan-Meier生存曲线分析CCI指数对生存时间及死亡率的影响。重要结论:533例2型糖尿病肾病患者纳入研究。所有患者的CCI评分均大于1,44.7%(238/533)的患者死亡。患者的死亡率随CCI评分增加而增加,CCI 1–2分患者的死亡率为21.0%(50/238),CCI 3–4分患者的死亡率为56.7%(135/238),CCI≥5分患者的死亡率为22.3%(53/238)。Logistic回归分析显示CCI评分、血红蛋白和血浆白蛋白水平是患者死亡率的预测因子(P<0.05)。方差分析结果显示,与CCI评分相对较低的患者相比,CCI评分越高的患者其血红蛋白水平较低,而血清肌酐较高,死亡率也更高。Kaplan-Meier生存曲线显示CCI评分越高的患者生存时间越短。CCI评分是一种简单易行且实用的评估疾病合并症的方法,可用于预测2型糖尿病肾病患者的死亡率。关注2型糖尿病肾病患者的合并症将有利于早期、有效治疗及改善预后。You-qun HUANG Rong GOU Yong-shu DIAO Qing-hua YIN Wen-xing FAN Ya-ping LIANG Yi CHEN Min WU Li ZANG Ling LI Jing ZANG Lu CHENG Ping FU Fang LIU 2014Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2014,15,1:23

14Genome and transcriptome analysis of the grapevine(Vitis vinifera L.) WRKY gene family显示文摘The plant WRKY gene family represents an ancient and complex class of zinc-finger transcription factors(TFs)that are involved in the regulation of various physiological processes,such as development and senescence,and in plant response to many biotic and abiotic stresses.Despite the growing number of studies on the genomic organisation of WRKY gene family in different species,little information is available about this family in grapevine(Vitis vinifera L.).In the present study,a total number of 59 putative grapevine WRKY transcription factors(VvWRKYs)were identified based on the analysis of various genomic and proteomic grapevine databases.According to their structural and phylogentic features,the identified grapevine WRKY transcription factors were classified into three main groups.In order to shed light into their regulatory roles in growth and development as well as in response to biotic and abiotic stress in grapevine,the VvWRKYs expression profiles were examined in publicly available microarray data.Bioinformatics analysis of these data revealed distinct temporal and spatial expression patterns of VvWRKYs in various tissues,organs and developmental stages,as well as in response to biotic and abiotic stresses.To also extend our analysis to situations not covered by the arrays and to validate our results,the expression profiles of selected VvWRKYs in response to drought stress,Erysiphe necator(powdery mildew)infection,and hormone treatments(salicilic acid and ethylene),were investigated by quantitative real-time reverse transcription PCR(qRT-PCR).The present study provides a foundation for further comparative genomics and functional studies of this important class of transcriptional regulators in grapevine.Min Wang Alessandro Vannozzi Gang Wang Ying-Hai Liang Giovanni Battista Tornielli Sara Zenoni Erika Cavallini Mario Pezzotti Zong-Ming(Max)Cheng 2014Horticulture Research2014,1,1:19
15Prevention and treatment of hepatic artery thrombosis after liver transplantation显示文摘BACKGROUND: Hepatic artery thrombosis (HAT) which is a serious complication after orthotopic liver transplanta- tion (OLT) remains a significant cause of graft loss. The purpose of this study was to sum up our experiences in the prevention, diagnosis and management of HAT after liver transplantation. METHODS: From April 1993 to September 2003, a total of 198 patients underwent OLT at our hospital. The hepatic artery was anastomosed using 7/0 prolane with running continuous suture in 96 patients (group 1) and with inter- rupted suture in 102 (group 2). Ultrasonography was per- formed every day in two weeks after operation and selec- tively afterwards. RESULTS: HAT occurred in 6 patients (6.3%, 6/96) of group 1, and in 1 (1%, 1/102) of group 2 (x2=4.027, P= 0.045). Six patients received emergency thrombectomy, and 1 conservative therapy but died from tumor recurrence eventually. Biliary complication developed in 3 patients af- ter thrombectomy of whom 2 died of liver failure and one waited for retransplantation. In the other 3 patients after thrombectomy, 1 died of renal failure, and 2 survived. The mortality of patients with HAT was 57.1% (4/7). CONCLUSIONS: The technique of hepatic arterial anasto- mosis is the key factor for the prevention of HAT. Routine ultrasonography is very important in early detection of HAT after OLT. Biliary complication is a severe outcome secondary to HAT.Shu-Sen Zheng, Zhi-Yong Yu, Ting-Bo Liang, Wei-Lin Wang, Yan Shen, Min Zhang, Xiao Xu and Jian Wu Hangzhou, China Centre of Organ Transplantation and Department o Hepatobiliary and Pancreatic Surgery, First Affiliated Hospital of Medica College, Zhcjiang University, Hangzhou 310003, China 2004Hepatobiliary & Pancreatic Diseases International2004,3,1:18
16N6-Methyladenine DNA Methylation in Japonica and Indica Rice Genomes and Its Association with Gene Expression,Plant Development, and Stress Responses显示文摘N6-Methyladenine (6mA)DNA methylation has recently been implicated as a potential new epigenetic marker in eukaryotes,including the dioot modelArabidopsis thaliana.However,the conservation and divergence of 6mA distribution patterns and functions in plants remain elusive.Here we report high-quality 6mA methylomes at single-nucleotide resolution in rice based on substantially improved genome sequences of two rice cultivars,Nipponbare (Nip;Japonica)and 93-11 (Indica).Analysis of 6mA genomic distribution and its association with transcription suggest that 6mA distribution and function is rather conserved between rice and Arabidopsis.We found that 6mA levels are positively correlated with the expression of key stressrelated genes,which may be responsible for the difference in stress tolerance between Nip and 93-11. Moreover,we showed that mutations in DDM1 cause defects in plant growth and decreased 6mA level. Our results reveal that 6mA is a conserved DNA modification that is positively associated with gene expression and contributes to key agronomic traits in plants.Qian Zhang Zhe Liang Xuean Cui Changmian Ji Yun Li Pingxian Zhang Jingrong Liu Adeel Riaz Pu Yao Min Liu Yunpeng Wang Tiegang Lu Hao Yu Donglei Yang Hongkun Zheng Xiaofeng Gu 2018Molecular Plant2018,11,12:18
17Surgical therapy and prognosis of sarcomatoid carcinoma of the gallbladder显示文摘BACKGROUND:Sarcomatoid carcinoma of the gallbladder is rare and its characteristics are poorly understood.This study aimed to understand the behavior and prognosis of sarcomatoid carcinoma of the gallbladder as well as its clinical manifestations and survival rate of patients after radical or palliative surgery,and to review the reported data worldwide and our 10 patients. METHODS:From 2004 to 2009,ten patients were pathologically diagnosed with sarcomatoid carcinoma of the gallbladder and underwent operation at our center.These characteristics,clinical presentations,tumor-node-metastasis(TNM)staging,surgical modes,and prognosis were reviewed,retrospectively.We collected the data of 46 patients reported in the English-language literature worldwide and analyzed the survival with ours.The survival rate was estimated using the Kaplan-Meier method,and was compared using the log-rank test. RESULTS:The median age of the 10 patients was 67 years (inter-quartile range 59-74 years),and the size of tumor inter- quartile ranged from 3.1 to 7.9 cm.In this series,9 patients received radical surgery,and one undewent palliative surgery. There was no surgical mortality,and one patient underwent a second operation because of liver metastasis.The median survival time of the patients was 9 months(inter-quartile range 6-12 months),with 3 patients still being alive until follow-up;however,two patients had tumor recurrence.The data from the 56 patients(10 patients in our series and 46 reported elsewhere)statistically indicated that the median age was 66 years(inter-quartile range 61-74.5 years)and the overall median survival was 5.5 months(inter-quartile range 2.5-10 months).The survival time in the patients undergoing radical surgery(n=42)was significantly longer than that in the patients undergoing palliative surgery(n=14)(P=0.031). CONCLUSIONS:The survival of the patients with sarcomatoid carcinoma of the gallbladder is poor.Some patients may die shortly after the surgery because of recurrence or metastasis. However,radical surgery is still necessary if possible.Hu, Zhen-Hua Li, Zhi-Wei Shen, Liang Zhang, Min Zheng, Shu-Sen 2010Hepatobiliary & Pancreatic Diseases International2010,9,2:16
18Coinfection with influenza A virus enhances SARS-CoV-2 infectivity显示文摘The upcoming flu season in the Northern Hemisphere merging with the current COVID-19 pandemic raises a potentially severe threat to public health.Through experimental coinfection with influenza A virus(IAV)and either pseudotyped or live SARS-CoV-2 virus,we found that IAV preinfection significantly promoted the infectivity of SARS-CoV-2 in a broad range of cell types.Remarkably,in vivo,increased SARS-CoV-2 viral load and more severe lung damage were observed in mice coinfected with IAV.Moreover,such enhancement of SARS-CoV-2 infectivity was not observed with several other respiratory viruses,likely due to a unique feature of IAV to elevate ACE2 expression.This study illustrates that IAV has a unique ability to aggravate SARS-CoV-2 infection,and thus,prevention of IAV infection is of great significance during the COVID-19 pandemic.Lei Bai Yongliang Zhao Jiazhen Dong Simeng Liang Ming Guo Xinjin Liu Xin Wang Zhixiang Huang Xiaoyi Sun Zhen Zhang Lianghui Dong Qianyun Liu Yucheng Zheng Danping Niu Min Xiang Kun Song Jiajie Ye Wenchao Zheng Zhidong Tang Mingliang Tang Yu Zhou Chao Shen Li Zhou Yu Chen Huan Yan Ke Lan Ke Xu 2021Cell Research2021,31,4:16

20Advanced oxidation protein products decrease expression of nephrin and podocin in podocytes via ROS-dependent activation of p38 MAPK显示文摘Accumulation of plasma advanced oxidation protein products(AOPPs) promotes progression of proteinuria and glomerulo-sclerosis.To investigate the molecular basis of AOPPs-induced proteinuria,normal Sprague-Dawley rats were treated with AOPPs-modified rat serum albumin.The expression of glomerular podocyte slit diaphragm(PSD)-associated proteins,nephrin and podocin,was significantly decreased coincident with the onset of albuminuria in rats treated with AOPPs.Chronic inhibi-tion of NADPH oxidase by apocynin prevented down-regulation of nephrin and podocin and decreased albuminuria in AOPPs-challenged rats.This suggested that accumulation of AOPPs promotes proteinuria,possibly via down-regulating the expression of PSD-associated proteins.YANG Li,LIANG Min,ZHOU QiuGen,XIE Di,LOU AiJu,ZHANG Xun & HOU FanFan Key Laboratory for Organ Failure Research,Division of Nephrology,Nanfang Hospital,Southern Medical University,Guangzhou 510515,China. 2010Science China(Life Sciences)2010,53,1:14
