| 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 | 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up. | Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu | 2018 | Science Bulletin2018,63,23: | 54 |

| 6 | Survey of convex optimization for aerospace applications显示文摘Convex optimization is a class of mathematical programming problems with polynomial complexity for which state-of-the-art, highly efficient numerical algorithms with predeterminable computational bounds exist. Computational efficiency and tractability in aerospace engineering, especially in guidance, navigation, and control (GN&C), are of paramount importance. With theoretical guarantees on solutions and computational efficiency, convex optimization lends itself as a very appealing tool. Coinciding the strong drive toward autonomous operations of aerospace vehicles, convex optimization has seen rapidly increasing utility in solving aerospace GN&C problems with the potential for onboard real-time applications. This paper attempts to provide an overview on the problems to date in aerospace guidance, path planning, and control where convex optimization has been applied. Various convexification techniques are reviewed that have been used to convexify the originally nonconvex aerospace problems. Discussions on how to ensure the validity of the convexification process are provided. Some related implementation issues will be introduced as well. | Xinfu Liu Ping Lu Binfeng Pan | 2017 | Astrodynamics2017,1,1: | 32 |
| 7 | 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 |

| 9 | Comparison of the Δ^(12) fatty acid desaturase gene between high-oleic and normal-oleic peanut genotypes显示文摘Δ12 fatty acid desaturase gene has been targeted as a logical candidate controlling the high oleate trait in peanut seeds.By RT-PCR method,the full-length cDNAs of Δ12 fatty acid desaturase gene were isolated from peanut(Arachis hypogaea L.) genotypes with normal and high ratio of oleic to linoleic acid,which were designated AhFAD2B and AhFAD2B',respectively.Sequence alignment of their coding regions revealed that an extra A was inserted at the position +442 bp of AhFAD2B' sequence of high oleic acid genotypes,which resulted in the shift of open reading frame and a truncated protein AhFAD2B',with the loss of one histidine box involved in metal ion complex required for the reduction of oxygen.Analysis of transcript level showed that the expression of Δ12 fatty acid desaturase gene in high oleic acid genotype was slightly lower than that in normal genotype.The enzyme activity experiment of yeast(Saccharomyces cerevisiae) cell transformed with AhFAD2B or AhFAD2B' proved that only AhFAD2B gene product showed significant Δ12 fatty acid desaturase activity,but AhFAD2B' gene product did not.These results suggested that the change of AhFAD2B' gene sequence resulted in lower activity or deactivation of Δ12 fatty acid desaturase in high oleic acid genotype. | ShanlinYu Lijuan Pan Qingli Yang Ping Min Zengkai Ren Hongsheng Zhang | 2008 | Journal of Genetics and Genomics2008,35,11: | 23 |

| 11 | Identification,localization and morphology of APUD cells in gastroenteropancreatic system of stomach-containing teleosts显示文摘AIM To identify the type localization andmorphology of APUD endocrine cells in thegastroenteropancreatic(GEP)system ofstomach-containing teleosts,and study APUDendocrine system in the stomach,intestine andpancreas of fish species.METHODS Two kinds of immunocytochemical(ICC)techniques of the streptavidin biotin-peroxidase complex(SABC)and streptavidin-peroxidase(S-P)method were used.Theidentification,localization and morphology ofAPUD endocrine cells scattered in the mucosa ofdigestive tract,intermuscular nerve plexus andglandular body of northern snakehead(Channaargus),ricefield eel(Monopterus albus),yellow catfish(Pelteobagrus fulvidraco),mandarinfish(Siniperca chuatsi),largemouthbass(Micropterus salmoides),orientalsheatfish(Silurus asotus),freshwater pomfret(Colossoma brachypomum)and nile tilapia(Tilapia nilotica)were investigated with 8 kindsof antisera.RESULTS The positive reaction of 5-hydroxytryptamine(5-HT)immunoreactiveendocrine(IRE)cells was found in the digestive tract and glandular body of 8 fish species indifferent degree.Only a few gastrin(GAS)-IREcells were seen in C.argus,M.albus and P.fulvidraco.Glucagon(GLU)-IRE cells were notfound in the digestive tract and glandular bodybut existed in pancreatic island of most fishspecies.The positive reaction of growthhormone(GH)-IRE cells was found only inpancreatic island of S.Chuatsi and S.Asotus,no positive reaction in the other 6 fish species.Somatostatin(SOM)-,calcitonin(CAL)-,neurofilament(NF)-and insulin(INS)-IRE cellsin the stomach,intestine and pancreas of 8 kindsof fish were different in distribution and types.The distribution of all 8 APUD cells was the mostin gastrointestinal epithelium mucosa and then indigestive glands.The positive reaction of SOM-and 5-HT-IRE cells was found in intermuscularnerve plexus of intestine of P.fulvidraco andS.chuatsi.Only GH-IRE cells were denselyscattered in the pancreatic islands of S.chuatsiand S.asotus,and odd distribution in thepancreas of S.asotus,SOM-IRE cells weredistributed in the pancreatic islands of S.asotus,C.Brachypomum and T.nilotica.There were INS-IRE cells in the pancreaticislands of S.chuatsi and S.asolus.Eightkinds of APUD cells had longer cell body andcytoplasmic process when they were located inthe gastrointestinal epithelium,and had shortercell body and cytoplasmic process in the gastricgland,and irregular shape in the esophagus andpancreatic island.CONCLUSION Eight kinds of IRE cells were identified in the GEP system of stomach-containing teleosts. These endocrine cells were scattered in gastrointestinal mucosa, intermuscular nerve plexus, gland body, pancreatic gland and islands under APUD system. CAL- and GH-IRE cells in the pancreatic islands of fishes showed functional diversity for these two hormones. Their morphological feature provides evidence of endocrine-paracrine and endocrine-exocrine acting mode. This research can morphologically prove that the GEP endocrine system of fish ( the lowest vertebrate) is almost the same as of mammal and human. | Qian Sheng Pan Zhi Ping Fang Feng Jie Huang | 2000 | World Journal of Gastroenterology2000,6,6: | 20 |

| 13 | Ubiquitination of Rheb governs growth factor-induced mTORC1 activation显示文摘Mechanistic target of rapamycin mTOR complex 1 (mTORC1)plays a key role in the integration of various environmental signals to regulate cell growth and metabolism,mTORC1 is recruited to the lysosome where it is activated by its interaction with GTP-bound Rheb GTPase.However,the regulatory mechanism of Rheb activity remains largely unknown.Here,we show that ubiquitination governs the nucleotide-bound status of Rheb.Lysosome-anchored E3 ligase RNF152 catalyzes Rheb ubiquitination and promotes its binding to the TSC complex.EGF enhances the deubiquitination of Rheb through AKT-dependent USP4 phosphorylation,leading to the release of Rheb from the TSC complex.Functionally,ubiquitination of Rheb is linked to mTORC1-mediated signaling and consequently regulates tumor growth.Thus,we propose a mechanistic model whereby Rheb-mediated mTORC1 activation is dictated by a dynamic opposing act between Rheb ubiquitination and deubiquitination that are catalyzed by RNF152 and USP4 respectively. | Lu Deng Lei Chen Linlin Zhao Yan Xu Xiaoping Peng Xinbo Wang Lin Ding Jiali Jin Hongqi Teng Yanming Wang Weijuan Pan Fei Yu Lujian Liao Li Li Xin Ge Ping Wang | 2019 | Cell Research2019,29,2: | 16 |
| 14 | Full robot-assisted gastrectomy with intracorporeal robot-sewn anastomosis produces satisfying outcomes显示文摘AIM:To evaluate the feasibility and safety of full robotassisted gastrectomy with intracorporeal robot handsewn anastomosis in the treatment of gastric cancer.METHODS:From September 2011 to March 2013,110consecutive patients with gastric cancer at the authors’institution were enrolled for robotic gastrectomies.According to tumor location,total gastrectomy,distal or proximal subtotal gastrectomy with D2 lymphadenectomy was fully performed by the da Vinci Robotic Surgical System.All construction,including Roux-en-Y jejunal limb,esophagojejunal,gastroduodenal and gastrojejunal anastomoses were fully carried out by the intracorporeal robot-sewn method.At the end of surgery,the specimen was removed through a 3-4 cm incision at the umbilicus trocar point.The details of the surgical technique are well illustrated.The benefits in terms of surgical and oncologic outcomes are well documented,as well as the failure rate and postoperative complications.RESULTS:From a total of 110 enrolled patients,radical gastrectomy could not be performed in 2 patients due to late stage disease;1 patient was converted to laparotomy because of uncontrollable hemorrhage,and1 obese patient was converted due to difficult exposure;2 patients underwent extra-corporeal anastomosis by minilaparotomy to ensure adequate tumor margin.Robot-sewn anastomoses were successfully performed for 12 proximal,38 distal and 54 total gastrectomies.The average surgical time was 272.52±53.91 min and the average amount of bleeding was 80.78±32.37 mL.The average number of harvested lymph nodes was 23.1±5.3.All specimens showed adequate surgical margin.With regard to tumor staging,26,32 and 46 patients were staged asⅠ,ⅡandⅢ,respectively.The average hospitalization time after surgery was 6.2 d.One patient experienced a duodenal stump anastomotic leak,which was mild and treated conservatively.One patient was readmitted for intra-abdominal infection and was treated conservatively.Jejunal afferent loop obstruction occurred in 1 patient,who underwent re-operation and recovered quickly.CONCLUSION:This technique is feasible and can produce satisfying postoperative outcomes.It is also convenience and reliable for anastomoses in gastrectomy.Full robotic hand-sewn anastomosis may be a minimally invasive technique for gastrectomy surgery. | Xin-Xin Liu Zhi-Wei Jiang Ping Chen Yan Zhao Hua-Feng Pan Jie-Shou Li | 2013 | World Journal of Gastroenterology2013,19,38: | 15 |

| 16 | Laparoscopic cystogastrostomy for the treatment of pancreatic pseudocysts: A case report显示文摘Pancreatic pseudocysts(PPs) are collections o pancreatic secretions that are lined by fibrous tissue and may contain necrotic debris or blood. The interventions including percutaneous, endoscopic o surgical approaches are based on the size, location symptoms and complications of a pseudocyst With the availability of advanced imaging system and cameras, better hemostatic equipments and excellent laparoscopic techniques, most pseudocyst can be found and managed by laparoscopy. We describe a case of a 30-year-old male patient with a pancreatic pseudocyst amenable to laparoscopi cystogastrostomy. An incision was made through the anterior gastric wall to expose the posterior gastri wall in close contact with the pseudocyst using an ultrasonically activated scalpel. Then, another incision was made for cystogastrostomy to obtain complete and unobstructed drainage. The patient recovered well after operation and was symptom-free during a 6-mo follow-up, suggesting that laparoscopi cystogastrostomy is a safe and effective alternative to open cystogastrostomy for minimally invasive management of PPs. | Qin-song Sheng Da-Zhi Chen Ren Lang Zhong-Kui Jin Dong-Dong Han Li-Xin Li Yong-Jiu Yang Ping Li Fei Pan Dong Zhang Zhao-Wei Qu Qiang He | 2008 | World Journal of Gastroenterology2008,14,30: | 15 |
| 17 | Liver Enzymes Concentrations Are Closely Related to Pre-diabetes:Findings of the Shanghai Diabetes Study Ⅱ (SHDS Ⅱ)显示文摘Objective To investigate the relationship of liver enzymes with hyperglycemia in a large population in Shanghai and identify the association between liver enzymes and insulin resistance.Methods A total of 3 756 participants were enrolled.Each participant underwent an oral glucose tolerance test and completed a questionnaire.Anthropometric indices were recorded and serum samples were collected for measurement.Results Liver enzymes concentrations were independently associated with i-IGT,IFG+IGT,and diabetes.With the increase of ALT and GGT concentrations,ORs for i-IGT,IFG+IGT,and diabetes increased gradually.By comparing patients in the highest quartile of GGT concentrations or ALT concentrations with those in the lowest quartile (Q1),ORs for i-IGT,IFG+IGT,or diabetes was significant after adjustment.Both ALT and GGT concentrations were linearly correlated with HOMA-IR and independently associated with HOMA-IR [ALT OR (95% CI):2.56 (1.51-4.34) P=0.00;GGT OR (95% CI):2.66 (1.53-4.65) P=0.00].Conclusion Serum ALT and GGT concentrations were closely related to pre-diabetes and diabetes in the Shanghai population and positively associated with insulin resistance. | GAO Fei PAN Jie Min HOU Xu Hong FANG Qi Chen LU Hui Juan TANG Jun Ling GU Hui Lin PAN Zhi Jian YAO You Hua SHEN Wei Zhen JIA Wei Ping | 2012 | Biomedical and Environmental Sciences2012,25,1: | 15 |
| 18 | Risk factors for sporadic colorectal cancer in southern Chinese显示文摘AIM:To investigate the role of smoking, alcohol drinking, family history of cancer, and body mass index(BMI) in sporadic colorectal cancer in southern Chinese.METHODS:A hospital-based case-control study was conducted from July 2002 to December 2008.There were 706 cases and 723 controls with their sex and age(within 5 years) matched.An unconditional logistic regression model was used to analyze the association between smoking, alcohol drinking, family history of cancer, BMI and sporadic colorectal cancer.RESULTS:No positive association was observed between smoking status and sporadic colorectal cancer risk.Compared with the non alcohol drinkers, the current and former alcohol drinkers had an increased risk of developing sporadic colorectal cancer(CRC)(adjusted OR = 8.61 and 95% CI = 6.15-12.05;adjusted OR = 2.30, 95% CI = 1.27-4.17).Moreover, the increased risk of developing sporadic CRC was significant in those with a positive family history of cancer(adjusted OR = 1.62, 95% CI = 1.12-3.34) and in those with their BMI ≥ 24.0 kg/m2(adjusted OR = 1.39, 95% CI = 1.10-1.75).Stratification analysis showed that the risk of developing both colon and rectal cancers was increased in current alcohol drinkers(adjusted OR = 7.60 and 95% CI = 5.13-11.25;adjusted OR = 7.52 and 95% CI = 5.13-11.01) and in those with their BMI ≥ 24.0 kg/m2(adjusted OR = 1.38 and 95% CI = 1.04-1.83;adjusted OR = 1.35 and 95% CI = 1.02-1.79).The risk of developing colon cancer, but not rectal cancer, was found in former alcohol drinkers and in those with a positive family history of cancer(adjusted OR = 2.51 and 95% CI = 1.24-5.07;adjusted OR = 1.82 and 95% CI = 1.17-2.82).CONCLUSION:Alcohol drinking, high BMI(≥ 24.0 kg/m2) and positive family history of cancer are the independent risk factors for colorectal cancer in southern Chinese. | Yi-Sheng Wei Jia-Chun Lu Lei Wang Ping Lan Hong-Jun Zhao Zhi-Zhong Pan Jun Huang Jian-Ping Wang | 2009 | World Journal of Gastroenterology2009,15,20: | 11 |
| 19 | Spatial distribution and deposition history of nonylphenol and bisphenol A in sediments from the Changjiang River(Yangtze River) Estuary and its adjacent East China Sea显示文摘Nonylphenol(NP) and bisphenol A(BPA) are endocrine disruptors causing harmful effects including feminization and carcinogenesis to various organisms,and consequently,their contamination in natural environment has received wide concerns.This study reports the distribution characteristics of NP and BPA in surface sediments and their deposition history based on a dated sediment core in the Changjiang River(Yangtze River) Estuary and its adjacent East China Sea.The contents of NP and BPA in surface sediments ranged from 1.56-35.8 and 0.72-13.2 ng/g(dry mass),respectively,with high values recorded in the two mud zones,the Changjiang River Estuarine Mud Zone and the Zhejiang Coastal Mud Zone.High values in the Zhejiang Coastal Mud Zone suggest the possibility of long distance transport of both contaminants through the Changjiang riverine plume.The contents were not correlated with the distance from the pollution source,indicating other factors including particle deposition rate and sediment grain size obviously affecting the distribution pattern.NP was also detected in a sediment core at layers deposited from the year of 1971 to 2001 with contents of up to 20.9 ng/g(dry mass).The deposition fluxes of NP varied from 0.68 to 17.9 ng/(cm2 · a) with peaks and valleys reflecting the traces of economic development history in China during the previous three decades.BPA was detected at sediment layers deposited from 1973 to 2001 with contents of up to 3.66 ng/g.The fluxes of BPA varied from 0.62 to 3.13 ng/(cm2 · a) showing a similar pattern as NP.The contents of NP and BPA also indicated potential risks on benthic organisms in the study area. | BIAN Haiyan LI Zhengyan LIU Ping PAN Jinfen | 2010 | Acta Oceanologica Sinica2010,29,5: | 10 |
