1Cancer statistics in China and United States,2022:profiles,trends,and determinants显示文摘Background:The cancer burden in the United States of America(USA)has decreased gradually.However,China is experiencing a transition in its cancer profiles,with greater incidence of cancers that were previously more common in the USA.This study compared the latest cancer profiles,trends,and determinants between China and USA.Methods:This was a comparative study using open-source data.Cancer cases and deaths in 2022 were calculated using cancer estimates from GLOBOCAN 2020 and population estimates from the United Nations.Trends in cancer incidence and mortality rates in the USA used data from the Surveillance,Epidemiology,and End Results program and National Center for Health Statistics.Chinese data were obtained from cancer registry reports.Data from the Global Burden of Disease 2019 and a decomposition method were used to express cancer deaths as the product of four determinant factors.Results:In 2022,there will be approximately 4,820,000 and 2,370,000 new cancer cases,and 3,210,000 and 640,000 cancer deaths in China and the USA,respectively.The most common cancers are lung cancer in China and breast cancer in the USA,and lung cancer is the leading cause of cancer death in both.Age-standardized incidence and mortality rates for lung cancer and colorectal cancer in the USA have decreased significantly recently,but rates of liver cancer have increased slightly.Rates of stomach,liver,and esophageal cancer decreased gradually in China,but rates have increased for colorectal cancer in the whole population,prostate cancer in men,and other seven cancer types in women.Increases in adult population size and population aging were major determinants for incremental cancer deaths,and case-fatality rates contributed to reduced cancer deaths in both countries.Conclusions:The decreasing cancer burden in liver,stomach,and esophagus,and increasing burden in lung,colorectum,breast,and prostate,mean that cancer profiles in China and the USA are converging.Population aging is a growing determinant of incremental cancer burden.Progress in cancer prevention and care in the USA,and measures to actively respond to population aging,may help China to reduce the cancer burden.Changfa Xia Xuesi Dong He Li Maomao Cao Dianqin Sun Siyi He Fan Yang Xinxin Yan Shaoli Zhang Ni Li Wanqing Chen 2022Chinese Medical Journal2022,,5:827
2Current cancer burden in China: epidemiology, etiology, and prevention显示文摘Cancer has become the most common cause of death in China.Owing to rapid economic development,improved livelihood,and shifts in risk factors,cancer epidemiology has experienced substantial changes during the past several decades.In this review,we aim to describe the current cancer epidemiology of the main types of cancer in China,report major risk factors associated with cancer development,and summarize the contributions of the Chinese government to controlling the cancer burden.A total of 4,064,000 new cases were diagnosed in China in 2016.The most frequent types are lung cancer(828,100;20.4%),colorectal cancer(408,000;10.0%),and gastric cancer(396,500;9.8%).Lung(657,000;27.2%),liver(336,400,13.9%),and stomach(288,500;12.0%)cancers are the 3 most deadly cancers in the general population.The 5-year survival rate for cancer has dramatically increased in recent decades.However,liver and particularly pancreatic cancers still have the poorest prognosis.The main modifiable risk factors associated with cancer development include infectious agents,smoking,alcohol consumption,obesity,unhealthful dietary habits,and inadequate physical activity.The Chinese government has made unremitting efforts to decrease the cancer burden,including cancer education and investment in cancer screening programs.Maomao Cao He Li Dianqin Sun Siyi He Xinxin Yan Fan Yang Shaoli Zhang Changfa Xia Lin Lei Ji Peng Wanqing Chen 2022Cancer Biology & Medicine2022,19,8:33
3Colorectal cancer burden,trends and risk factors in China:A review and comparison with the United States显示文摘Objective:China and the United States(the U.S.)have the heaviest colorectal cancer(CRC)burden with considerable variations in temporal trends.This study aims to analyze the temporal patterns of CRC burden and its risk factors in China and the U.S.across the past three decades.Methods:Data were extracted from the Global Burden of Disease(GBD)Study in 2019,including cases,deaths,disability-adjusted life-years(DALYs),age-standardized rate(ASR),and summary exposure value(SEV)of CRC in China and the U.S.between 1990 and 2019.Annual average percentage changes(AAPCs)of CRC burden were calculated using the Joinpoint regression model.The mortality in CRC attributable to potential risk factors was characterized by countries,gender,and age groups.Results:In 2019,there were 607,900 and 227,241 CRC cases,and 261,777 and 84,026 CRC deaths in China and the U.S.,respectively.The age-standardized incidence rate(ASIR)was 30.55 per 100,000 in China and 41.86 per100,000 in the U.S.,and the age-standardized mortality rate(ASMR)was 13.86 per 100,000 in China and 14.77 per100,000 in the U.S.CRC incidence,mortality,and DALY rate in the U.S.showed downward trends in the past three decades(AAPC=-0.47,-1.06,and-0.88,respectively),while upward trends were observed in China(AAPC=3.11,1.05,and 0.91,respectively).Among the cause of CRC,the leading risk factor contributing to CRC death was low milk in China and smoking in the U.S.,respectively.Conclusions:From 1990 to 2019,the burden of CRC in China increased dramatically,particularly for males and middle-aged and elderly people.The management of the major risk factors associated with the high burden of CRC should be enhanced.Qianru Li Hongliang Wu Maomao Cao He Li Siyi He Fan Yang Xinxin Yan Shaoli Zhang Yi Teng Changfa Xia Ji Peng Wanqing Chen 2022Chinese Journal of Cancer Research2022,34,5:6
4Stomach cancer burden in China: Epidemiology and prevention显示文摘In 2020, stomach cancer was the fifth most commonly diagnosed cancer and the fourth leading cause of cancer-related death worldwide. Due to the relatively huge population base and the poor survival rate, stomach cancer is still a threat in China, and accounts for nearly half of the cases worldwide. Fortunately, in China, the incidence and mortality rates of stomach cancer presented a declining trend owing to the change of individual life styles and the persistent efforts to prevent stomach cancer from the governments at all levels. Helicobacter pylori(H. pylori)infection, poor eating habits, smoking, history of gastrointestinal disorders, and family history of stomach cancer are the main risk factors for stomach cancer in China. As a result, by taking risk factors for stomach cancer into account, specific preventive measures, such as eradicating H. pylori and implementing stomach cancer screening projects, should be taken to better prevent and decrease the burden of stomach cancer.Xinxin Yan Lin Lei He Li Maomao Cao Fan Yang Siyi He Shaoli Zhang Yi Teng Qianru Li Changfa Xia Wanqing Chen 2023Chinese Journal of Cancer Research2023,35,2:2
5CALTPP:A general program to calculate thermophysical properties显示文摘A program CALTPP(CALculation of ThermoPhysical Properties)is developed in order to provide various thermophysical properties such as diffusion coefficient,interfacial energy,thermal conductivity,viscosity and molar volume mainly as function of temperature and composition.These thermophysical properties are very important inputs for microstructure simulations and mechanical property predictions.The general structure of CALTPP is briefly described,and the CALPHAD-type models for the description of these thermophysical properties are presented.The CALTPP program contains the input module,calculation and/or optimization modules and output module.A few case studies including(a)the calculation of diffusion coefficient and optimization of atomic mobility,(b)the calculation of solid/liquid,coherent solid/solid and liquid/liquid interfacial energies,(c)the calculation of thermal conductivity,(d)the calculation of viscosity,and(e)the establishment of molar volume database in binary and ternary alloys are demonstrated to show the features of CALTPP.It is expected that CALTPP will be an effective contribution in both scientific research and education.Yuling Liu Cong Zhang Changfa Du Yong Du Zhoushun Zheng Shuhong Liu Lei Huang Shiyi Wen Youliang Jin Huaqing Zhang Fan Zhang George Kaptay 2020Journal of Materials Science & Technology2020,42,7:2
6Histones released by NETosis enhance the infectivity of SARS-CoV-2 by bridging the spike protein subunit 2 and sialic acid on host cells显示文摘Neutrophil extracellular traps(NETs)can capture and kill viruses,such as influenza viruses,human immunodeficiency virus(HIV),and respiratory syncytial virus(RSV),thus contributing to host defense.Contrary to our expectation,we show here that the histones released by NETosis enhance the infectivity of SARS-CoV-2,as found by using live SARS-CoV-2 and two pseudovirus systems as well as a mouse model.The histone H3 or H4 selectively binds to subunit 2 of the spike(S)protein,as shown by a biochemical binding assay,surface plasmon resonance and binding energy calculation as well as the construction of a mutant S protein by replacing four acidic amino acids.Sialic acid on the host cell surface is the key molecule to which histones bridge subunit 2 of the S protein.Moreover,histones enhance cell-cell fusion.Finally,treatment with an inhibitor of NETosis,histone H3 or H4,or sialic acid notably affected the levels of sgRNA copies and the number of apoptotic cells in a mouse model.These findings suggest that SARS-CoV-2 could hijack histones from neutrophil NETosis to promote its host cell attachment and entry process and may be important in exploring pathogenesis and possible strategies to develop new effective therapies for COVID-19.Weiqi Hong Jingyun Yang Jun Zou Zhenfei Bi Cai He Hong Lei Xuemei He Xue Li Aqu Alu Wenyan Ren Zeng Wang Xiaohua Jiang Kunhong Zhong Guowen Jia Yun Yang Wenhai Yu Qing Huang Mengli Yang Yanan Zhou Yuan Zhao Dexuan Kuang Junbin Wang Haixuan Wang Siyuan Chen Min Luo Ziqi Zhang Tiangi Lu Li Chen Haiying Que Zhiyao He Qiu Sun Wei Wang Guobo Shen Guangwen Lu Zhiwei Zhao Li Yang Jinliang Yang Zhenling Wang Jiong Li Xiangrong Song Lunzhi Dai Chong Chen Jia Geng Maling Gou Lu Chen Haohao Dong Yong Peng Canhua Huang Zhiyong Qian Wei Cheng Changfa Fan Yuquan Wei Zhaoming Su Aiping Tong Shuaiyao Lu Xiaozhong Peng Xiawei Wei 2022Cellular & Molecular Immunology2022,19,5:2
7Burden of liver cancer:From epidemiology to prevention显示文摘In this review,we offer a concise overview of liver cancer epidemiology in China and worldwide from the official databases of GLOBOCAN 2020 and the National Cancer Registry in China.We also summarized the evidence for the main risk factors associated with liver cancer risk and discuss strategies implemented in China to control the liver cancer burden.Overall,liver cancer was the sixth most commonly diagnosed cancer and the third leading cause of cancer-related death worldwide in 2020.Although China contributed to nearly half of cases across the world alone,the incidence and mortality rates of liver cancer presented a declining trend owing to the persistent efforts from the governments at all levels.The current liver cancer burden in China still faces an arduous challenge due to the relatively large population base as well as the substantially low survival rate(12.1%).To better control the liver cancer burden with the lowest cost,specific measures should be conducted by reducing exposure to established risk factors such as hepatitis B infection and aflatoxin.The promotion of surveillance is also an important method to prolong the survival of liver cancer.This review will provide basic information for future direction on the control of liver cancer burden.Qianru Li Maomao Cao Lin Lei Fan Yang He Li Xinxin Yan Siyi He Shaoli Zhang Yi Teng Changfa Xia Wanqing Chen 2022Chinese Journal of Cancer Research2022,34,6:2
8Cancer profiles in China and comparisons with the USA:a comprehensive analysis in the incidence,mortality,survival,staging,and attribution to risk factors显示文摘China faces a disproportionate cancer burden to the population size and is undergoing a transition in the cancer spectrum.We extracted data in five aspects of cancer incidence,mortality,survival,staging distributions,and attribution to risk factors in China,the USA and worldwide from open-source databases.We conducted a comprehensive secondary analysis of cancer profiles in China in the above aspects,and compared cancer statistics between China and the USA.A total of 4,546,400 new cancer cases and 2,992,600 deaths occurred in China in 2020,accounting for 25.1%and 30.2%of global cases,respectively.Lifestyle-related cancers including lung cancer,colorectal cancer,and breast cancer showed an upward trend and have been the leading cancer types in China.41.6%of new cancer cases and 49.3%of cancer deaths occurred in digestive-system cancers in China,and the cancers of esophagus,nasopharynx,liver,and stomach in China accounted for over 40%of global cases.Infection-related cancers showed the highest population-attributable fractions among Chinese adults,and most cancers could be attributed to behavioral and metabolic factors.The proportions of stage I for most cancer types were much higher in the USA than in China,except for esophageal cancer(78.2%vs.41.1%).The 5-year relative survival rates in China have improved substantially during 2000–2014,whereas survival for most cancer types in the USA was significantly higher than in China,except for upper gastrointestinal cancers.Our findings suggest that although substantial progress has been made in cancer control,especially in digestive system cancers in China,there was still a considerable disparity in cancer burden between China and the USA.More robust policies on risk factors and standardized screening practices are urgently warranted to curb the cancer growth and improve the prognosis for cancer patients.Siyi He Changfa Xia He Li Maomao Cao Fan Yang Xinxin Yan Shaoli Zhang Yi Teng Qianru Li Wanqing Chen 2024Science China(Life Sciences)2024,67,1:2

10Acquisition of taxane resistance by p53 inactivation in ovarian cancer cells显示文摘Ovarian cancer is one of the most common gynecologic malignancies in women and has a poor prognosis.Taxanes are a class of standard first-line chemotherapeutic agents for the treatment of ovarian cancer.However,tumor-intrinsic and acquired resistance to taxanes poses major challenges to improving clinical outcomes.Hence,there is an urgent clinical need to understand the mechanisms of resistance in order to discover potential biomarkers and therapeutic strategies to increase taxane sensitivity in ovarian cancer.Here,we report the identification of an association between the TP53 status and taxane sensitivity in ovarian cancer cells through complementary experimental and informatics approaches.We found that TP53 inactivation is associated with taxane resistance in ovarian cancer cells,supported by the evidence from(i)drug sensitivity profiling with bioinformatic analysis of large-scale cancer therapeutic response and genomic datasets and(ii)gene signature identification based on experimental isogenic cell line models.Further,our studies revealed TP53-dependent gene expression patterns,such as overexpression of ACSM3,as potential predictive biomarkers of taxane resistance in ovarian cancer.The TP53-dependent hyperactivation of the WNT/β-catenin pathway discovered herein revealed a potential vulnerability to exploit in developing combination therapeutic strategies.Identification of this genotype-phenotype relationship between the TP53 status and taxane sensitivity sheds light on TP53-directed patient stratification and therapeutic discoveries for ovarian cancer treatment.Changfa Shu Xi Zheng Alafate Wuhafu Danielle Cicka Sean Doyle Qiankun Niu Dacheng Fan Kun Qian Andrey AIvanov Yuhong Du Xiulei Mo Haian Fu 2022Acta Pharmacologica Sinica2022,43,9:1
11Animal models for COVID-19:advances,gaps and perspectives显示文摘COVID-19,caused by SARS-CoV-2,is the most consequential pandemic of this century.Since the outbreak in late 2019,animal models have been playing crucial roles in aiding the rapid development of vaccines/drugs for prevention and therapy,as well as understanding the pathogenesis of SARS-CoV-2 infection and immune responses of hosts.However,the current animal models have some deficits and there is an urgent need for novel models to evaluate the virulence of variants of concerns(VOC),antibodydependent enhancement(ADE),and various comorbidities of COVID-19.This review summarizes the clinical features of COVID-19 in different populations,and the characteristics of the major animal models of SARS-CoV-2,including those naturally susceptible animals,such as non-human primates,Syrian hamster,ferret,minks,poultry,livestock,and mouse models sensitized by genetically modified,AAV/adenoviral transduced,mouse-adapted strain of SARS-CoV-2,and by engraftment of human tissues or cells.Since understanding the host receptors and proteases is essential for designing advanced genetically modified animal models,successful studies on receptors and proteases are also reviewed.Several improved alternatives for future mouse models are proposed,including the reselection of alternative receptor genes or multiple gene combinations,the use of transgenic or knock-in method,and different strains for establishing the next generation of genetically modified mice.Changfa Fan Yong Wu Xiong Rui Yuansong Yang Chen Ling Susu Liu Shunan Liu Youchun Wang 2022Signal Transduction and Targeted Therapy2022,7,8:0
12A mouse model for SARS-CoV-2-induced acute respiratory distress syndrome显示文摘Dear Editor,The COVID-19 pandemic has covered more than 200 countries and regions around the world since its outbreak in January 2020.To date,the SARS-CoV-2 virus has caused>1.2 million deaths.The mortality rate of COVID-19 is closely concerned with the clinical symptoms of the patients from mild-to-severe disease.Notably,in its most severe form,COVID-19 leads to life-threatening pneumonia and acute respiratory distress syndrome(ARDS),which is mostly accom-panied by a hyperactive immune response called'cytokine storm'and has high death rates from 40 to 50%.Weiqi Hong Jingyun Yang Zhenfei Bi Cai He Hong Lei Wenhai Yu Yun Yang Changfa Fan Shuaiyao Lu Xiaozhong Peng Xiawei Wei 2021Signal Transduction and Targeted Therapy2021,6,2:0
13The Infection and Pathogenicity of SARS-CoV-2 Variant B.1.351 in hACE2 Mice显示文摘Dear Editor,Since the outbreak of COVID-19 at the end of 2019,its causative agent SARS-Co V-2 has been spreading around the world for one and half a year.During the long global circulation of SARS-Co V-2,mutations in the viral genome gradually emerged and accumulated。Qi Chen Xing-Yao Huang Ying Tian Changfa Fan Mengxu Sun Chao Zhou Ruiting Li Rong-Rong Zhang Guizhen Wu Cheng-Feng Qin 2021Virologica Sinica2021,36,5:0
14Lung cancer burden and trends from 2000 to 2018 in China:Comparison between China and the United States显示文摘Objective: This study aims to provide an analysis of the current status and trends of lung cancer incidence and mortality rates in China, comparing trends with those in the United States(U.S.).Methods: Data on lung cancer incidence and mortality rates spanning 2000 to 2018 were extracted from the China Cancer Registry Annual Report and the Surveillance, Epidemiology, and End Results database for China and the U.S., respectively. Crude incidence and mortality rates were calculated by sex and age, with age-standardized incidence rates(ASIR) and mortality rates(ASMR) calculated using the Segi-Doll world standard population.Trend analyses employed Joinpoint regression models to determine average annual percentage change(AAPC).The study also assessed the proportion of new cases and deaths by sex and age.Results: In 2018, the ASIR of lung cancer for males in China was 50.72 per 100,000 and the ASMR was 39.69 per 100,000, the ASIR for females was 26.25 per 100,000 and the ASMR was 15.24 per 100,000. Both ASIR and ASMR were higher in males and the highest in the population aged 65 years and older, with the lowest among those aged 20-49 years. In China, female ASIR demonstrated an increasing trend(AAPC: 1.16%), while ASMR decreased in both sexes(AAPCs:-0.48% for males,-1.00% for females). The U.S. exhibited decreasing trends in both ASIR and ASMR across sexes and age groups.Conclusions: The study identified an increasing trend in lung cancer incidence among females and a decreasing mortality trend in both sexes in China. These trends are likely linked to factors such as smoking prevalence,advancements in cancer screening, and improved medical care. The findings underscore the need for tailored lung cancer prevention measures in China, particularly the reinforcement of anti-smoking policies.Yi Teng Changfa Xia Maomao Cao Fan Yang Xinxin Yan Siyi He Mengdi Cao Shaoli Zhang Qianru Li Nuopei Tan Jiachen Wang Wanqing Chen 2023Chinese Journal of Cancer Research2023,35,6:0
15Cancer statistics for young adults aged 20 to 49 years in China from 2000 to 2017:a population-based registry study显示文摘An increasing cancer incidence among adults younger than 50 years has been reported for several types of cancer in multiple countries.We aimed to report cancer profiles and trends among young adults in China.Data from the China Cancer Registry Annual Report were used to estimate incidence and mortality among young adults(ages 20–49 years)in China in 2017,and an age-period-cohort model was employed to estimate the average annual percent change(AAPC)in incidence and mortality from 2000 to 2017.All 25 cancer types were grouped into obesity-or overweight-associated cancers(12 cancer types)and additional cancers(13 cancer types).In 2017,there were 681,178new cases and 214,591 cancer deaths among young adults in China.Among young adults,the most common cancers were thyroid,breast,cervical,liver,lung,and colorectal cancer,and the leading causes of cancer deaths were liver,lung,cervical,stomach,breast,and colorectal cancer.From 2000 to 2017,the cancer incidence increased for all cancers combined among young adults,with the highest AAPC(1.46%)for adults aged 20–24 years,while cancer mortality decreased,with the highest AAPC(-1.63%)for those aged 35–39 years.In conclusion,the cancer incidence in China has increased among young adults,while cancer mortality has decreased for nearly all ages.Cancer control measures,such as obesity control and appropriate screening,may contribute to reducing the increasing cancer burden among young adults.Yi Teng Changfa Xia He Li Maomao Cao Fan Yang Xinxin Yan Siyi He Mengdi Cao Shaoli Zhang Qianru Li Wanqing Chen 2024Science China(Life Sciences)2024,67,4:0
