| 2 | 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 |
| 3 | Analysis of in vivo patterns of caspase 3 gene expression in primary hepatocellular carcinoma and its relationship to p21^(WAF1) expression and hepatic apoptosis显示文摘AIM To detect the expression of caspase 3gene in primary human hepatocellular carcinoma(HCC)and investigate its relationship to p21WAF1gene expression and HCC apoptosis.METHODS In situ hybridization was employedto determine caspase 3 and p21WAF1expression inHCC.In situ end-labeling was used to detecthepatocytic apoptosis in HCC.RESULTS Twenty-one of 39(53.8%)cases ofHCC were found to express caspase 3transcripts,while 45.2% of HCC failed toexpress caspase 3.Non-cancerous adjacent livertissues showed more positive caspase 3(87.5%,7/8)as compared with HCC(P<0.05).The expression of caspase 3 is correlated withHCC differentiation,72.2%(13/18)ofmoderately to highly differentiated HCC showedcaspase 3 transcripts positive,while only 38.1%of poorly differentiated HCC harbored caspase 3transcripts(P<0.05).No relationship wasfound between caspase 3 expression and tumorsize or grade or metastasis,although 52.5%(5/8)of HCC with metastasis were caspase 3positive and a little higher than that with nometastasis(51.6%,P>0.05).Expression of caspase 3 alone did not affect the apoptosisindex(AI)of HCC.The AI was 7.12%o in caspase3-positive tumors(n=21),while in caspase 3-negative cases(n=18)6.59%0(P>0.05).Expression of caspase 3 clearly segregated withp21WAF1positive tumors as compared withp21WAF1-negative cases(16 of 23,69.6% versus5 of 16,31.3%)with statistical significance(P=0.017).In the cases with positive caspase 3and negative p21WAF1,the Al was found slightlyhigher,but with no statistical significance,thanthat with expression of p21WAF1and caspase 3(7.21‰ vs 6.98‰,P>0.05).CONCLUSION Loss of caspase 3 expressionmay contribute to HCC carcinogenesis,althoughthe expression of caspase 3 does not correlatewell with cell apoptosis in HCC.p21WAF1may bemerely one of the inhibitors which can reducecaspase 3 mediated cell apoptosis in HCCs. | Bao Hua Sun Jun Zhang Bao JǜWang Xi Ping Zhao You Kun Wang Zhi Qun Yu Dong Liang Yang Lian Jie Hao Department of Clinical Immunology,Tongji Hospital,Tongji Medical University,Wuhan 430030,Hubei Province,China | 2000 | World Journal of Gastroenterology2000,6,3: | 65 |

| 6 | Advanced treatment of dyeing wastewater towards reuse by the combined Fenton oxidation and membrane bioreactor process显示文摘The performance of combined Fenton oxidation and membrane bioreactor (MBR) process for the advanced treatment of an effluent from an integrated dyeing wastewater treatment plant was evaluated. The experimental results revealed that under the optimum Fenton oxidation conditions (initial pH 5, H 2 O 2 dosage 17 mmol/L, and Fe 2+ 1.7 mmol/L) the average total organic carbon (TOC) and color removal ratios were 39.3% and 69.5% after 35 min of reaction, respectively. Results from Zahn-Wallens Test also represented that Fenton process was effective to enhance the biodegradability of the test wastewater. As for the further purification of MBR process, TOC removal capacity was examined at different hydraulic retention times (HRT) of 10, 18 and 25 hr. Under the optimum HRT of 18 hr, the average TOC concentration and color of the final MBR effluent were 16.8 mg/L and 2 dilution time, respectively. The sludge yield coefficient was 0.13 g MLSS/g TOC and TOC degradation rate was 0.078 kg TOC/(m 3 ·day). The final effluent of MBR can meet the reuse criteria of urban recycling water-water quality standard for miscellaneous water consumption GBT18920-2002. | Fei Feng Zhenliang XU Xiaohuan Li Wenting You Yang Zhen | 2010 | Journal of Environmental Sciences2010,22,11: | 27 |

| 9 | A single center investigation of bare-metal or drug-eluting stent restenosis from 1633 consecutive Chinese Han ethnic patients显示文摘Background Stents are widely used in China but the clinical impression is somehow that restenosis is less common because of the lower prevalence of coronary artery disease (CAD) and associated risk factors in Chinese populations. However, no large-sample published studies are available on angiographic stent restenosis including those of bare-metal stent (BMS) or drug-eluting stent (DES) in Chinese Han ethnic population. Mothods A total of 1633 consecutive patients with CAD who had undergone coronary stenting, quantitative coronary angiography (QCA) were retrospectively studied. At the time of stent implantation and at 7 months post-stenting 675 patients had a follow-up angiography. Statistical analysis was made with the chi-square test for categorical variables, unpaired t test for continuous variables, univariate or multivariate regression for baseline and angiographic characteristics and the Kaplan-Meier method for rate of target lesion revascularization (TLR). Results Stent restenosis was defined as ≥50% diameter stenosis in the dilated segment. A total of 675 patients with 1074 lesions were subjected to angiographic follow-up for 7 months on average. Of these lesions, 448 were implanted with BMS whereas 626 lesions with DES. At 7 months, bare-metal in-stent restenosis occured in 148 lesions (33.0%), and bare metal in-segment restenosis in 155 lesions (34.6%) in contrast to drug-eluting in-stent restenosis in 48 lesions (7.7%) and drug-eluting in-segment restenosis in 73 lesions (11.7%) (P<0.001 compared with BMS respectively). Late loss in both in-stent and in segment was higher in BMS than in DES groups [(1.00±0.69) vs (0.28±0.52); (0.78±0.71) vs (0.21±0.52), P<0.001 respectively]. Angulated lesion, lesion length, pre-procedural minimal luminal diameter (MLD), and BMS were independent predictors for TLR, (P<0.01 respectively), whereas current smoker, ostial lesion, and stent overlapping, post-procedure in-stent MLD, lesion length, and stent types were independent predictors for in-segment restenosis (P<0.01 respectively). Standard coronary risk factors such as hypertension, hyperlipidemia, diabetes, and history of CAD were not associated with a higher rate of restenosis caused by BMS or DES implantation in our Chinese Han ethnic population. Conclusions Coronary stenting including BMS or DES implantation in Chinese Han ethnic patients is associated with a restenosis rate comparable to that demonstrated in previous studies from the western countries, and predictors of stent restenosis are somehow different from those in the western population. | XU Bo LI Jian-jun YANG Yue-jin MA Wei-hua CHEN Ji-lin QIAO Shu-bin QIN Xue-wen YAO Min LIU Hai-bo WU Yong-jian YUAN Jin-qing CHEN Jue YOU Shi-jie DAI Jun XIA Ran GAO Run-lin | 2006 | Chinese Medical Journal2006,,7: | 23 |
| 10 | Blood Lipid Profile and Prevalence of Dyslipidemia in Chinese Adults显示文摘Objective To investigate the plasma lipid levels in a national representative sample of subjects and to determine the prevalence of dyslipidemia in the Chinese population.Methods Plasma lipid profile was analyzed using the data obtained during the Chinese national nutrition and health survey(CNHS)in 2002 which involved 14 252 participants at the age of 18 years or older.Results The mean levels of total cholesterol(TC),triglyceride(TG)and high density lipoprotein cholesterol(HDL-C)in the participants were 3.81 mmol/L,1.10 mmol/L,and 1.30 mmol/L,respectively.In the groups of participants at the age of 18-44 years,45-59 years,and over 60 years the mean TC level was 3.70 mmol/L,4.09 mmol/L and 4.21 mmol/L,respectively,and the mean TG level was 07 mmol/L,1.21 mmol/L,1.20 mmol/L,1.29 mmol/L,1.33 mmol/L,and 1.33 mmol/L,respectively.The prevalence of dyslipidemia in Chinese adults was 18.6% and 22.2% in males and 15.9% in females.Dyslipidemia prevalence was higher in urban districts than in rural areas(21.0% vs.17.7%).The prevalence of hypercholesterolemia,hypertriglyceridemia,and low HDL cholesterol was 2.9%,11.9%,and 7.4% respectively among the participants.Conclusion Dyslipidemia has become one of the important health risk factors in the Chinese population.There is no significantly difference in the prevalence of dyslipidemia between the groups of participants at the age of 45-59 years and over 60 years.This study provides important lipid profile data for policy making and guideline development for the prevention of dyslipidemia in the Chinese population. | WEN-HUA ZHAO JIAN ZHANG YI ZHAI YUE YOU QING-QING MAN CHUN-RONG WANG HONG LI YING LI XIAO-GUANG YANG | 2007 | Biomedical and Environmental Sciences2007,20,4: | 22 |

| 12 | Expert consensus on the use of human serum albumin in critically ill patients显示文摘Introduction Human serum albumin(HSA)is a non-glycosylated,negatively charged,single-chain polypeptide composed of 585 amino acid residues with a relative molecular mass of 66.438 kD.It is synthesized by the liver at a rate of approximately 200 mg·kg^(-1)·day^(-1),with a half-life of 21 days,and subjected to catabolism in the muscles,liver,and kidneys at a rate of 4%per day.[1]Albumin,accounting for 60%of the total plasma protein,has various physiological functions,[2]such as maintaining 70%to 80%of effective plasma colloid osmotic pressure,coordinating vascular endothelial integrity,anti-oxidant and anti-inflammatory activities,maintaining the acidbase balance,and participating in the transport,distribution,and metabolism of a variety of endogenous and exogenous substances. | Yue-Tian Yu Jiao Liu Bo Hu Rui-Lan Wang Xiang-Hong Yang Xiu-Ling Shang Gang Wang Chang-Song Wang Bai-Ling Li Ye Gong Sheng Zhang Xin Li Lu Wang Min Shao Mei Meng Feng Zhu You Shang Qiang-Hong Xu Zhi-Xiong Wu De-Chang Chen | 2021 | Chinese Medical Journal2021,,14: | 22 |
| 13 | Early screening and diagnosis strategies of pancreatic cancer:a comprehensive review显示文摘Pancreatic cancer is a highly malignant digestive system tumor with a poor prognosis.Most pancreatic cancer patients are diagnosed at an advanced stage or even metastasis due to its highly aggressive characteristics and lack of typical early symptoms.Thus,an early diagnosis of pancreatic cancer is crucial for improving its prognosis.Currently,screening is often applied in high-risk individuals to achieve the early diagnosis of pancreatic cancer.Fully understanding the risk factors of pancreatic cancer and pathogenesis could help us identify the high-risk population and achieve early diagnosis and timely treatment of pancreatic cancer.Notably,accumulating studies have been undertaken to improve the detection rate of different imaging methods and the diagnostic accuracy of endoscopic ultrasound-guided fine-needle aspiration(EUS-FNA)which is the golden standard for pancreatic cancer diagnosis.In addition,there are currently no biomarkers with sufficient sensitivity and specificity for the diagnosis ofpancreatic cancer to be applied in the clinic. As the only serum biomarkerapproved by the United States Food and Drug Administration, carbohydrateantigen 19-9 (CA19-9) is not recommended to be used in the early screeningof pancreatic cancer because of its limited specificity. Recently, increasingnumbers of studies focused on the discovering of novel serum biomarkersand exploring their combination with CA19-9 in the detection of pancreaticcancer. Besides, the application of liquid biopsy involving circulating tumor cells(CTCs), circulating tumor DNA (ctDNA), microRNAs (miRNAs), and exosomesin blood and biomarkers in urine, and saliva in pancreatic cancer diagnosis aredrawing more and more attention. Furthermore, many innovative technologiessuch as artificial intelligence, computer-aided diagnosis system, metabolomicstechnology, ion mobility spectrometry (IMS) associated technologies, and novelnanomaterials have been tested for the early diagnosis of pancreatic cancer andhave shown promising prospects. Hence, this review aims to summarize therecent progress in the development of early screening and diagnostic methods,including imaging, pathological examination, serological examination, liquidbiopsy, as well as other potential diagnostic strategies for pancreatic cancer. | Jinshou Yang Ruiyuan Xu Chengcheng Wang Jiangdong Qiu Bo Ren Lei You | 2021 | Cancer Communications2021,41,12: | 23 |
| 14 | Screening for gastric cancer in China:Advances,challenges and visions显示文摘Gastric cancer(GC)is one of the major cancers in China and all over the world.Most GCs are diagnosed at an advanced stage with unfavorable prognosis.Along with some other countries,China has developed the government-funded national screening programs for GC and other major cancers.GC screening has been shown to effectively decrease the incidence of and mortality from GC in countries adopting nationwide screening programs(Japan and Korea)and in studies based on selected Chinese populations.The screening of GC relies mostly on gastroendoscopy,the accuracy,reliability and safety of which have been indicated by previous studies.However,considering its invasive screening approach,requirements on skilled endoscopists and pathologists,and a high cost,developing noninvasive methods to amend endoscopic screening would be highly needed.Numerous studies have examined biomarkers for GC screening and the combination of biomarkers involving pepsinogen,gastrin,and Helicobacter pylori antibodies has been proposed for risk stratification,seeking to narrow down the high-risk populations for further endoscopy.Despite all the achievements of endoscopic screening,evidence on appropriate screening age,intervals for repeated screening,novel biomarkers promoting precision prevention,and health economics need to be accumulated to inform policymakers on endoscopic screening in China.With the guide of Health China 2030 Planning Outline,we have golden opportunities to promote prevention and control of GC.In this review,we summarize the characteristics of screening programs in China and other East Asian countries and introduce the past and current approaches and strategies for GC screening,aiming for featuring the latest advances and key challenges,and illustrating future visions of GC screening. | Xiaohan Fan Xiangxiang Qin Yang Zhang Zhexuan Li Tong Zhou Jingying Zhang Weicheng You Wenqing Li Kaifeng Pan | 2021 | Chinese Journal of Cancer Research2021,33,2: | 21 |

| 18 | How Could Agricultural Land Systems Contribute to Raise Food Production Under Global Change?显示文摘To feed the increasing world population,more food needs to be produced from agricultural land systems.Solutions to produce more food with fewer resources while minimizing adverse environmental and ecological consequences require sustainable agricultural land use practices as supplementary to advanced biotechnology and agronomy.This review paper,from a land system perspective,systematically proposed and analyzed three interactive strategies that could possibly raise future food production under global change.By reviewing the current literatures,we suggest that cropland expansion is less possible amid fierce land competition,and it is likely to do less in increasing food production.Moreover,properly allocating crops in space and time is a practical way to ensure food production.Climate change,dietary shifts,and other socio-economic drivers,which would shape the demand and supply side of food systems,should be taken into consideration during the decision-making on rational land management in respect of sustainable crop choice and allocation.And finally,crop-specific agricultural intensification would play a bigger role in raising future food production either by increasing the yield per unit area of individual crops or by increasing the number of crops sown on a particular area of land.Yet,only when it is done sustainably is this a much more effective strategy to maximize food production by closing yield and harvest gaps. | WU Wen-bin YU Qiang-yi Verburg H Peter YOU Liang-zhi YANG Peng TANG Hua-jun | 2014 | Journal of Integrative Agriculture2014,13,7: | 19 |

0.05 ) 。Immunofluorescence 证明有在正常脉管的 endothelial 的 SR-PSOX 的低表示并且在感染的容器的每层提高了表示,当从 endothelial 传播到包围感染变得更坏的纸巾时。共焦的显微镜学证明 SR-PSOX 的表示在肝肝硬化在渗入的淋巴细胞被提高,并且表示铺平,这对在门 hepatis 和叶的发炎的度相称。结论:在外部血的单核白血球的 CXCL16/SR-PSOX 的表达式比在控制在交流病人是显著地更高的。CXCL16/SR-PSOX-mediated 发炎可以贡献交流的致病,并且 CXCL16 可以在致病和发展起一个重要作用是在人。 | YANG Hui-ling XU Yang-yan DU Li-fen LIU Chang-hui ZHAO Qiang WEI Wu-jie YOU Yong QUAN Zhi-hua | 2008 | Chinese Medical Journal2008,,2: | 17 |
| 20 | Angiographic prevalence of myocardial bridging in a defined very large number of Chinese patients with chest pain显示文摘背景:心肌内冠的动脉被称为的 epicardial 分割的肌纤维 overlying 心肌的衔接(MB ) 。MB 的可变流行与小、大的样品尺寸研究在尸体和 angiographic 系列被描述了。另外,没有类似的学习在中国人口被报导。这研究的目的是调查 MB 的 angiographic 流行在连续有从我们的中心的胸痛的 37,106 个中国病人。方法:我们进行了观察研究在经历的病人之中与 MB 评估连续案例选择冠的血管造影术,并且在很大的样品尺寸的这研究分析了 angiograhic 流行和 MB 的临床的特征。结果:在有胸痛的 37 105 个病人之中,我们以一种回顾的方式与 1011 MB 发现了 1002 个案例,并且全面流行是 2.70% 。尽管(991/1002 ) 超过 99% 病人有单个桥牌, 8 个案例被发现有超过二 MB (七与二,和一与三) 。没有动脉粥样硬化患者损害,总的来说 54.39% 案例(545/1002 ) 有 MB,并且(973/1011 )96.24% 在左前面的下降冠的动脉(男孩) 衔接定位了,主要在男孩的中间(792/1011, 78.33%) 。根据诺贝尔分类,单个桥(n=991 ) ,阻塞的 <50% 是占优势的(471/991, 47.52%) 。完全, 50%-69% 占了 34.81%(345/991 ) ,阻塞的 >70% 是 17.65%(175/991 ) 。结论:这些数据证明在有胸痛的中国病人的 angiographically 可检测的 MB 的流行类似于以前的研究的那些,与在这种很大的样品尺寸的 2.7% 流行。 | LI Jian-jun SHANG Zheng-lu YAO Min LI Jie YANG Yue-jin CHEN Ji-lin QIAO Shu-bin MA Wei-hua QIN Xue-wen LIU Hai-bo WU Yong-jian YUAN Jin-qing CHEN Jue YOU Shi-jie DAI Jun XU Bo XIA Ran GAO Run-lin | 2008 | Chinese Medical Journal2008,,5: | 17 |
