4The incidences and mortalities of major cancers in China, 2009显示文摘In 2012, the National Central Cancer Registry (NCCR) of China collected cancer registration information for the year 2009 from local cancer registries and analyzed it to describe the incidences and mortalities of cancers in China. Based on the data quality criteria from NCCR, data from 104 registries covering 85,470,522 people (57,489,009 in urban areas and 27,981,513 in rural areas) were checked and evaluated. The data from 72 registries were qualified and accepted for the cancer registry annual report in 2012. The total cancer incident cases and cancer deaths were 244,366 and 154,310, respectively. The morphologically verified cases accounted for 67.23%, and 3.14% of the incident cases only had information from death certifications. The crude incidence in the Chinese cancer registration areas was 285.91/ 100,000 (317.97/100,000 in males and 253.09/100,000 in females). The age-standardized rates for incidences based on the Chinese standard population (ASRIC) and the world standard population (ASRIW) were 146.87/100,000 and 191.72/100,000, respectively, with a cumulative incidence of 22.08%. The cancer mortality in the Chinese cancer registration areas was 180.54/100,000 (224.20/100,000 in males and 135.85/100,000 in females). The age-standardized rates for mortalities based on the Chinese standard population (ASRMC) and the world standard population (ASRMW) were 85.06/100,000 and 115.65/100,000, respectively, and the cumulative mortality was 12.94% . Lung cancer, gastric cancer, colorectal cancer, liver cancer, esophageal cancer, pancreatic cancer, encephaloma, lymphoma, female breast cancer, and cervical cancer were the most common cancers, accounting for 75% of all cancer cases. Lung cancer, gastric cancer, liver cancer, esophageal cancer, colorectal cancer, pancreatic cancer, breast cancer, encephaloma, leukemia, and lymphoma accounted for 80% of all cancer deaths. The cancer registration's population coverage has been increasing, and its data quality is improving. As the basis of the cancer control program, the cancer registry plays an important role in directing anticancer strategies in the medium and long term. Because cancer burdens are different in urban and rural areas in China, prevention and control efforts should be based on practical situations.Wanqing Chen Rongshou Zheng Siwei Zhang Ping Zhao Guanglin Li Lingyou Wu Jie He 2013Chinese Journal of Cancer2013,32,3:111
5Report of incidence and mortality in China cancer registries, 2009显示文摘Objective: The National Central Cancer Registry (NCCR) collected cancer registration data in 2009 from local cancer registries in 2012, and analyzed to describe cancer incidence and mortality in China. Methods: On basis of the criteria of data quality from NCCR, data submitted from 104 registries were checked and evaluated. There were 72 registries' data qualified and accepted for cancer registry annual report in 2012. Descriptive analysis included incidence and mortality stratified by area (urban/rural), sex, age group and cancer site. The top 10 common cancers in different groups, proportion and cumulative rates were also calculated. Chinese population census in 1982 and Segi's population were used for age-standardized incidence/mortality rates. Results: All 72 cancer registries covered a total of 85,470,522 population (57,489,009 in urban and 27,981,513 in rural areas). The total new cancer incident cases and cancer deaths were 244,366 and 154,310, respectively. The morphology verified cases accounted for 67.23%, and 3.14% of incident cases only had information from death certifications. The crude incidence rate in Chinese cancer registration areas was 285.91/100,000 (males 317.97/100,000, females 253.09/100,000), age-standardized incidence rates by Chinese standard population (ASIRC) and by world standard population (ASIRW) were 146.87/100,000 and 191.72/100,000 with the cumulative incidence rate (0-74 age years old) of 22.08%. The cancer incidence and ASIRC were 303.39/100,000 and 150.31/100,000 in urban areas whereas in rural areas, they were 249.98/100,000 and 139.68/100,000, respectively. The cancer mortality in Chinese cancer registration areas was 180.54/100,000 (224.20/100,000 in males and 135.85/100,000 in females), age-standardized mortality rates by Chinese standard population (ASMRC) and by world standard population (ASMRW) were 85.06/100,000 and 115.65/100,000, and the cumulative incidence rate (0-74 age years old) was 12.94%. The cancer mortality and ASMRC were 181.86/100,000 and 80.86/100,000 in urban areas, whereas in rural areas, they were 177.83/100,000 and 94.40/100,000 respectively. Lung cancer, gastric cancer, colorectal cancer, liver cancer, esophageal cancer, pancreas cancer, encephaloma, lymphoma, female breast cancer and cervical cancer, were the most common cancers, accounting for 75% of all cancer cases in urban and rural areas. Lung cancer, gastric cancer, liver cancer, esophageal cancer, colorectal cancer, pancreatic cancer, breast cancer, encephaloma, leukemia and lymphoma accounted for 80% of all cancer deaths. The cancer spectrum showed difference between urban and rural areas, males and females. The main cancers in rural areas were cancers of the stomach, followed by esophageal cancer, lung cancer, liver cancer and colorectal cancer, whereas the main cancer in urban areas was lung cancer, followed by liver cancer, gastric cancer and colorectal cancer. Conclusions: The coverage of cancer registration population has been increasing and data quality is improving. As the basis of cancer control program, cancer registry plays an important role in making anticancer strategy in medium and long term. As cancer burdens are different between urban and rural areas in China, prevention and control should be implemented based on practical situation.Wanqing Chen Rongshou Zheng Siwei Zhang Ping Zhao Guanglin Li Lingyou Wu Jie He 2013Chinese Journal of Cancer Research2013,25,1:202
6Modeling study of regional severe hazes over mid-eastern China in January 2013 and its implications on pollution prevention and control显示文摘The Nested Air Quality Prediction Model System(NAQPMS)was used to investigate the temporal and spatial variations of PM2.5over tropospheric central eastern China in January 2013.The impact of regional transport and its implications on pollution prevention and control were also examined.Comparison between simulated and observed PM2.5showed NAQPMS was able to reproduce the evolution of PM2.5during heavy haze episodes.The results indicated that regional transport of PM2.5played an important role in regional haze episodes in the city cluster including Hebei,Beijing and Tianjin(HBT).The cross-city clusters transport outside HBT and transport among cities inside HBT contributed 20%–35%and 26%–35%of PM2.5as compared with local emission,in HBT respectively.To meet the Air Quality Standards for Grade II,90%,90%and65%of emissions would have to be cut down in Hebei,Tianjin and Beijing,if non-control strategy was taken in the surrounding city clusters of HBT.This implicated that control of emissions in one city cluster is not sufficient to reduce regional haze events,and joint efforts among city clusters are essential.Besides regional transports,two-way feedback between boundary-layer evolution and PM2.5also significantly contributed to the formation of heavy hazes,which contributed 30%of monthly average PM2.5concentration in HBT.WANG ZiFa LI Jie WANG Zhe YANG WenYi TANG Xiao GE BaoZhu YAN PinZhong ZHU LiLi CHEN XueShun CHEN HuanSheng WAND Wei LI JianJun LIU Bing WANG XiaoYan WAND Wei ZHAO YiLin LU Ning SU DeBin 2014Science China Earth Sciences2014,57,1:106
7Liver cancer incidence and mortality in China: Temporal trends and projections to 2030显示文摘Objective: Liver cancer is one of the most common cancers and major cause of cancer deaths in China,which accounts for over 50% of new cases and deaths worldwide.The systematic liver cancer statistics including of projection through 2030 could provide valuable information for prevention and control strategies in China,and experience for other countries.Methods: The burden of liver cancer in China in 2014 was estimated using 339 cancer registries' data selected from Chinese National Cancer Center(NCC).Incident cases of 22 cancer registries were applied for temporal trends from 2000 to 2014.The burden of liver cancer through 2030 was projected using age-period-cohort model.Results: About 364,800 new cases of liver cancer(268,900 males and 95,900 females) occurred in China,and about 318,800 liver cancer deaths(233,500 males and 85,300 females) in 2014.Western regions of China had the highest incidence and mortality rates.Incidence and mortality rates decreased by about 2.3% and 2.6% per year during the period of 2000-2014,respectively,and would decrease by more than 44% between 2014 and 2030 in China.The young generation,particularly for those aged under 40 years,showed a faster down trend.Conclusions: Based on the analysis,incidence and mortality rates of liver cancer are expected to decrease through 2030,but the burden of liver cancer is still serious in China,especially in rural and western areas.Most cases of liver cancer in China can be prevented through vaccination and more prevention efforts should be focused on high risk groups.Rongshou Zheng Chunfeng Qu Siwei Zhang Hongmei Zeng Kexin Sun Xiuying Gu Changfa Xia Zhixun Yang He Li Wenqiang Wei Wanqing Chen Jie He 2018Chinese Journal of Cancer Research2018,30,6:132

10Cancer incidence and mortality in China, 2014显示文摘Background: National Central Cancer Registry of China(NCCRC) updated nationwide cancer statistics using population-based cancer registry data in 2014 collected from all available cancer registries.Methods: In 2017, 449 cancer registries submitted cancer registry data in 2014, among which 339 registries' data met the criteria of quality control and were included in analysis. These cancer registries covered 288,243,347 population, accounting for about 21.07% of the national population in 2014. Numbers of nationwide new cancer cases and deaths were estimated using calculated incidence and mortality rates and corresponding national population stratified by area, sex, age group and cancer type. The world Segi's population was applied for agestandardized rates.Results: A total of 3,804,000 new cancer cases were diagnosed, the crude incidence rate was 278.07/100,000(301.67/100,000 in males, 253.29/100,000 in females) and the age-standardized incidence rate by world standard population(ASIRW) was 186.53/100,000. Calculated age-standardized incidence rate was higher in urban areas than in rural areas(191.6/100,000 vs. 179.2/100,000). South China had the highest cancer incidence rate while Southwest China had the lowest incidence rate. Cancer incidence rate was higher in female for population between20 to 54 years but was higher in male for population younger than 20 years or over 54 years. A total of 2,296,000 cancer deaths were reported, the crude mortality rate was 167.89/100,000(207.24/100,000 in males,126.54/100,000 in females) and the age-standardized mortality rate by world standard population(ASMRW) was106.09/100,000. Calculated age-standardized mortality rate was higher in rural areas than in urban areas(110.3/100,000 vs. 102.5/100,000). East China had the highest cancer mortality rate while North China had the lowest mortality rate. The mortality rate in male was higher than that in female. Common cancer types and major causes of cancer death differed between age group and sex.Conclusions: Heavy cancer burden and its disparities between area, sex and age group pose a major challenge to public health in China. Nationwide cancer registry plays a crucial role in cancer prevention and control.Wanqing Chen Kexin Sun Rongshou Zheng Hongmei Zeng Siwei Zhang Changfa Xia Zhixun Yang He Li Xiaonong Zou Jie He 2018Chinese Journal of Cancer Research2018,30,1:832

12Identification of a novel coronavirus causing severe pneumonia in human:a descriptive study显示文摘Background:Human infections with zoonotic coronaviruses(CoVs),including severe acute respiratory syndrome(SARS)-CoV and Middle East respiratory syndrome(MERS)-CoV,have raised great public health concern globally.Here,we report a novel batorigin CoV causing severe and fatal pneumonia in humans.Methods:We collected clinical data and bronchoalveolar lavage(BAL)specimens from five patients with severe pneumonia from Wuhan Jinyintan Hospital,Hubei province,China.Nucleic acids of the BAL were extracted and subjected to next-generation sequencing.Virus isolation was carried out,and maximum-likelihood phylogenetic trees were constructed.Results:Five patients hospitalized from December 18 to December 29,2019 presented with fever,cough,and dyspnea accompanied by complications of acute respiratory distress syndrome.Chest radiography revealed diffuse opacities and consolidation.One of these patients died.Sequence results revealed the presence of a previously unknownβ-CoV strain in all five patients,with 99.8%to 99.9%nucleotide identities among the isolates.These isolates showed 79.0%nucleotide identity with the sequence of SARS-CoV(GenBank NC_004718)and 51.8%identity with the sequence of MERS-CoV(GenBank NC_019843).The virus is phylogenetically closest to a bat SARS-like CoV(SL-ZC45,GenBank MG772933)with 87.6%to 87.7%nucleotide identity,but is in a separate clade.Moreover,these viruses have a single intact open reading frame gene 8,as a further indicator of bat-origin CoVs.However,the amino acid sequence of the tentative receptor-binding domain resembles that of SARS-CoV,indicating that these viruses might use the same receptor.Conclusion:A novel bat-borne CoV was identified that is associated with severe and fatal respiratory disease in humans.Li-Li Ren Ye-Ming Wang Zhi-Qiang Wu Zi-Chun Xiang Li Guo Teng Xu Yong-Zhong Jiang Yan Xiong Yong-Jun Li Xing-Wang Li Hui Li Guo-Hui Fan Xiao-Ying Gu Yan Xiao Hong Gao Jiu-Yang Xu Fan Yang Xin-Ming Wang Chao Wu Lan Chen Yi-Wei Liu Bo Liu Jian Yang Xiao-Rui Wang Jie Dong Li Li Chao-Lin Huang Jian-Ping Zhao Yi Hu Zhen-Shun Cheng Un-Lin Liu Zhao-Hui Qian Chuan Qin Qi Jin Bin Cao Jian-Wei Wang 2020Chinese Medical Journal2020,,9:99
13Towards 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
14On the origin and continuing evolution of SARS-CoV-2显示文摘The SARS-Co V-2 epidemic started in late December 2019 in Wuhan, China, and has since impacted a large portion of China and raised major global concern. Herein, we investigated the extent of molecular divergence between SARS-CoV-2 and other related coronaviruses. Although we found only 4% variability in genomic nucleotides between SARS-CoV-2 and a bat SARS-related coronavirus(SARSr-CoV;Ra TG13), the difference at neutral sites was 17%, suggesting the divergence between the two viruses is much larger than previously estimated. Our results suggest that the development of new variations in functional sites in the receptor-binding domain(RBD) of the spike seen in SARS-Co V-2 and viruses from pangolin SARSr-Co Vs are likely caused by natural selection besides recombination. Population genetic analyses of 103 SARS-CoV-2 genomes indicated that these viruses had two major lineages(designated L and S), that are well defined by two different SNPs that show nearly complete linkage across the viral strains sequenced to date. We found that L lineage was more prevalent than the S lineage within the limited patient samples we examined. The implication of these evolutionary changes on disease etiology remains unclear.These findings strongly underscores the urgent need for further comprehensive studies that combine viral genomic data, with epidemiological studies of coronavirus disease 2019(COVID-19).Xiaolu Tang Changcheng Wu Xiang Li Yuhe Song Xinmin Yao Xinkai Wu Yuange Duan Hong Zhang Yirong Wang Zhaohui Qian Jie Cui Jian Lu 2020National Science Review2020,7,6:67
15Inflammatory mediators and microcirculatory disturbance in acute pancreatitis显示文摘BACKGROUND:Inflammatory mediators are not only initiation factors of acute pancreatitis(AP)but also key factors causing pancreatic hemorrhage and necrosis,which damage important organs such as the heart,brain,liver, kidney and lung.Microcirculatory disturbance in AP has attracted widespread attention.In order to provide a theoretical basis for clinical therapy of AP,it is very important to explore the effect of inflammatory mediators on microcirculatory disturbance in this disease. DATA SOURCES:In this review,the impact of inflammatory mediators on microcirculatory disturbance in AP was reviewed according to the literature,especially the articles indexed in PubMed and books published in China and reports from websites. RESULTS:At present,inflammatory mediation and micro- circulatory disturbance are the two major hypotheses to explain the development of AP.Although experimental studies have shown that inflammatory mediators induce or aggravate microcirculatory disturbance,the clinical application of these findings is still difficult because the inflammatory mediators are diverse and their research is not comprehensive and thorough. CONCLUSION:It is very important to explore the influence of inflammatory mediators on microcirculatory disturbance in AP.Zhang, Xi-Ping Li, Zhi-Jun Zhang, Jie 2009Hepatobiliary & Pancreatic Diseases International2009,8,4:60

192018 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 2018Science Bulletin2018,63,23:54
20A Rare Allele of GS2 Enhances Grain Size anc Grain Yield in Rice显示文摘谷物尺寸决定谷物重量并且影响谷物质量。调整谷物尺寸的几主要量的特点 loci (QTL ) 被克隆;然而,我们调整米饭谷物的尺寸的内在的机制的理解仍然保持碎片。这里,我们报导克隆和主导的 QTL 的描述,染色体 2 上的谷物尺寸(GS2 ) 编码调整生长的因素 4,一个 transcriptional 管理者。GS2 本地化到原子核并且可以充当抄写使活跃之物。影响 microRNA 的有约束力的地点的 GS2 的一个稀罕变化, OsmiR396c,原因提高了 GS2/OsGRF4 的表示。GS2 表示的增加导致更大的房间和房间的增加的数字,它因此提高谷物重量和产量。进米饭栽培变种的 GS2/OsGRF4 的这稀罕等位基因的介绍能显著地提高谷物重量和增加谷物产量,用在引起产量很高的米饭变化的可能的应用。Jiang Hu Yuexing Wang Yunxia Fang Longjun Zeng Jie Xu Haiping Yu Zhenyuan Shi Jiangjie Pan Dong Zhang Shujing Kang Li Zhu Guojun Dong Longbiao Guo Dali Zeng Guangheng Zhang Lihong Xie Guosheng Xiong Jiayang Li Qian Qian 2015Molecular Plant2015,8,10:57
