We determined the GC global, regional, and national burden profiles and changes in incidence for 3 sequential 5-year intervals from 2003 to 2017.Methods: The latest incidence and mortality estimates of GC from 185 countries and regions were extracted from the GLOBOCAN 2022 database. The 5-year interval age-standardised incidence rates(ASIRs) were evaluated using cancer registry data from volumes X±XII of the Cancer Incidence in Five Continents(CI5). Correlation analysis was used to evaluate the relationship between ASIR or the age-standardised mortality rate(ASMR) and the Human Development Index(HDI).Results: There was an estimated global 968,000 new GC cases and 660,000 deaths in 2022, with male predominance. GC ASIRs and ASMRs were 9.2 and 6.1 per 100,000 persons, respectively. East Asia had the highest burden, with 53.8% of cases and 48.2% of deaths among all geographic regions. There was a significant correlation between ASIR and HDI. Over three 5-year intervals from 2003 to 2017, the incidence of GC notably decreased in most countries but peaked at 2008±2012 in New Zealand, Turkey, and South Africa. Several countries in Europe, Oceania, and America suggest an increasingly concerning trend among younger individuals, especially females.Conclusions: GC is a significant health issue, especially among males and in geographic regions with an HDI, such as eastern Asia. While the incidence of GC is decreasing in many countries due to prevention efforts and improved treatments, a rising trend persists among younger individuals. Comprehensive prevention strategies tailored to different age patterns are clearly needed.展开更多

This analysis investigated deaths and disability-adjusted life years(DALYs) with respect to etiologies and risk factors for liver cancer in China and worldwide.Methods: Global and China-specific data were collected on liver cancer deaths, DALYs, and age-standardized rates(ASRs) from the Global Burden of Disease Study 2019 database. Liver cancer etiologies were classified into five groups and risk factors were categorized into three levels. Each proportion of liver cancer burden was calculated in different geographic regions. The joinpoint regression model were used to assess the trends from 1990±2019.Results: Liver cancer accounted for 484,577 deaths worldwide in 2019 with an ASR of 5.9 per 100,000 population. China had an elevated liver cancer death ASR in 2019 and males had an ASR 1.7 times the global rate. The global ASR for DALYs peaked at 75±79 years of age but peaked earlier in China. Hepatitis B virus was the prominent etiology globally(39.5%) and in China(62.5%), followed by hepatitis C virus and alcohol consumption. In high sociodemographic index countries, non-alcoholic steatohepatitis has gained an increasing contribution as an etiologic factor. The liver cancer burden due to various etiologies has decreased globally in both genders. However, metabolic risk factors, particularly obesity, have had a growing contribution to the liver cancer burden, especially among males.Conclusions: Despite an overall decreasing trend in the liver cancer burden in China and worldwide, there has been a rising contribution from metabolic risk factors, highlighting the importance of implementing targeted prevention and control strategies that address regional and gender disparities.展开更多

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.展开更多

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.展开更多

文摘Objective:This study aimed to provide a comprehensive overview of the global burden of esophageal cancer(EC)and determine the temporal trends and factors influencing changes in the global burden.Methods:The latest incidence and mortality data for EC worldwide were obtained from GLOBALCAN 2022.The mortality and disability-adjusted life years(DALYs)rates for EC from 1990±2019 were sourced from the 2019 Global Burden of Diseases.Trends in EC mortality and DALYs attributable to 11 risk factors or clusters of risk were analyzed using the joinpoint regression model.The trends in age-related EC burden were assessed using a decomposition approach.Results:An estimated 511,054 new cases of EC were diagnosed in 2022 with 445,391 deaths worldwide.Approximately 75%of cases and deaths occurred in Asia.Nearly 50%of global EC deaths and DALYs were attributed to tobacco use in men in 2019,while 20%were attributed to high body mass index(BMI)in women.From 1990±2019,EC deaths and DALYs attributable to almost all risk factors had declining trends,while EC deaths and DALYs attributed to high BMI in men had upward trends.The age-related EC burden exhibited an upward trend driven by population growth and aging,which contributed to 307.4 thousand deaths and 7.2 million DALYs due to EC.Conclusions:The EC burden remains substantial worldwide.Effective tobacco and obesity control measures are critical for addressing the risk-attributable burden of EC.Population growth and aging pose challenges for EC prevention and control efforts.

文摘A good Ti-based joint implant should prevent stress shielding and achieve good bioactivity and anti-infection performance.To meet these requirements,the low-elastic-modulus alloy—Ti–35Nb–2Ta–3Zr—was used as the substrate,and functional coatings that contained bioceramics and Ag ions were prepared for coating on TiO_(2)nanotubes(diameter:(80±20)nm and(150±40)nm)using anodization,deposition,and spin-coating methods.The effects of the bioceramics(nano-β-tricalcium phosphate,microhydroxyapatite(micro-HA),and meso-CaSiO_(3))and Ag nanoparticles(size:(50±20)nm)on the antibacterial activity and the tribocorrosion,corrosion,and early in vitro osteogenic behaviors of the nanotubes were investigated.The tribocorrosion and corrosion results showed that the wear rate and corrosive rate were highly dependent on the features of the nanotube surface.Micro-HA showed great wear resistance with a wear rate of(1.26±0.06)×10^(−3)mm^(3)/(N·m)due to adhesive and abrasivewear.Meso-CaSiO_(3)showed enhanced cell adhesion,proliferation,and alkaline phosphatase activity.The coatings that contained nano-Ag exhibited good antibacterial activity with an antibacterial rate of≥89.5%against Escherichia coli.These findings indicate that hybrid coatings may have the potential to accelerate osteogenesis.

文摘Objective: The burden of gastric cancer(GC) across different age groups needs updating. We determined the GC global, regional, and national burden profiles and changes in incidence for 3 sequential 5-year intervals from 2003 to 2017.Methods: The latest incidence and mortality estimates of GC from 185 countries and regions were extracted from the GLOBOCAN 2022 database. The 5-year interval age-standardised incidence rates(ASIRs) were evaluated using cancer registry data from volumes X±XII of the Cancer Incidence in Five Continents(CI5). Correlation analysis was used to evaluate the relationship between ASIR or the age-standardised mortality rate(ASMR) and the Human Development Index(HDI).Results: There was an estimated global 968,000 new GC cases and 660,000 deaths in 2022, with male predominance. GC ASIRs and ASMRs were 9.2 and 6.1 per 100,000 persons, respectively. East Asia had the highest burden, with 53.8% of cases and 48.2% of deaths among all geographic regions. There was a significant correlation between ASIR and HDI. Over three 5-year intervals from 2003 to 2017, the incidence of GC notably decreased in most countries but peaked at 2008±2012 in New Zealand, Turkey, and South Africa. Several countries in Europe, Oceania, and America suggest an increasingly concerning trend among younger individuals, especially females.Conclusions: GC is a significant health issue, especially among males and in geographic regions with an HDI, such as eastern Asia. While the incidence of GC is decreasing in many countries due to prevention efforts and improved treatments, a rising trend persists among younger individuals. Comprehensive prevention strategies tailored to different age patterns are clearly needed.

文摘Objective: Liver cancer is a major health concern globally and in China. This analysis investigated deaths and disability-adjusted life years(DALYs) with respect to etiologies and risk factors for liver cancer in China and worldwide.Methods: Global and China-specific data were collected on liver cancer deaths, DALYs, and age-standardized rates(ASRs) from the Global Burden of Disease Study 2019 database. Liver cancer etiologies were classified into five groups and risk factors were categorized into three levels. Each proportion of liver cancer burden was calculated in different geographic regions. The joinpoint regression model were used to assess the trends from 1990±2019.Results: Liver cancer accounted for 484,577 deaths worldwide in 2019 with an ASR of 5.9 per 100,000 population. China had an elevated liver cancer death ASR in 2019 and males had an ASR 1.7 times the global rate. The global ASR for DALYs peaked at 75±79 years of age but peaked earlier in China. Hepatitis B virus was the prominent etiology globally(39.5%) and in China(62.5%), followed by hepatitis C virus and alcohol consumption. In high sociodemographic index countries, non-alcoholic steatohepatitis has gained an increasing contribution as an etiologic factor. The liver cancer burden due to various etiologies has decreased globally in both genders. However, metabolic risk factors, particularly obesity, have had a growing contribution to the liver cancer burden, especially among males.Conclusions: Despite an overall decreasing trend in the liver cancer burden in China and worldwide, there has been a rising contribution from metabolic risk factors, highlighting the importance of implementing targeted prevention and control strategies that address regional and gender disparities.

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.

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.

文摘Oil dispersible suspension concentrates are safe,green,and environmentally friendly formulations.Problems such as layering,pasting,and bottoming are frequently encountered during the production,storage,and transportation process.Polyisobutylene succinimide functions as a dispersant and exhibits great potential to improve the physical stability of the oil dispersible suspension concentrate.From a microscopic perspective,the sorption characteristics of the polyisobutylene succinimide dispersant T151 on penoxsulam particle surfaces were comprehensively evaluated with XPS,FTIR,and SEM.The T151 adsorption procedure complied with a pseudo-second-order kinetic adsorption model,and it was a kind of physical sorption with an Ea of 22.57 kJ⋅mol^(−1).The T151 sorption model was consistent with the Langmuir isotherm.The adsorption process was spontaneous and followed by an entropy increase.TheΔH^(θ)of dispersant T151 on the surface of penoxsulam particles was 31.59 kJ⋅mol^(−1).The adsorption procedure was endothermic,and the primary force was hydrogen bonding.The XPS results showed that the F and S electronic peaks at the penoxsulam interface decreased,and that the C electronic peak increased significantly after the adsorption of dispersant T151,indicating the adsorption on the surface of penoxsulam particles.The results of this study provide a vital theoretical basis for the application of polyisobutylene succinimide dispersants in oil dispersible suspension systems.

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.

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.

文摘Objective:Population-level economic burden is essential for prioritizing healthcare resources and healthcare budget making in the future.However,little is known about the economic burden of lung cancer in China.Methods:A prevalence-based approach was adopted to estimate the economic burden of lung cancer,including direct expenditure(medical and non-medical)and indirect cost(disability and premature death).Data on direct expenditure and work-loss days per patient in each year post-diagnosis were obtained from two primary surveys.Other parameters were obtained from literatures and official reports.Projections were conducted based on varying parameters.All expenditure data were reported in United States dollars(USD)using 2017 value(exchange rate:1 USD=6.760 CNY),with the discount rate of 3%.Results:The total economic burden of lung cancer was estimated to be 25,069 million USD in China in 2017(0.121%of gross domestic productivity,GDP).The estimated direct expenditure was 11,098 million USD,up to1.43%of total healthcare expenditure for China,covering 10,303 million USD and 795 million USD for medical and non-medical expenditure,respectively.The estimated indirect cost was 13,971 million,including 1,517 million USD due to disability and 12,454 million USD due to premature death.Under current assumptions,the projected total economic burden would increase to 30.1 billion USD,40.4 billion USD,and 53.4 billion USD in 2020,2025,and 2030,accounting for 0.121%,0.131%,and 0.146%of China's GDP,respectively.However,if China meets the United Nation sustainable development goal of reducing premature death from non-communicable diseases by one-third by 2030,the total economic burden in 2030 would be 31.9 billion USD,0.087%of China's GDP.Conclusions:The economic burden of lung cancer in China in 2017 is substantial and more likely to increase significantly in the future.Policy makers need to take urgent actions in budget making for health systems.The economic burden could be alleviated by reducing the disease burden of lung cancer via effective control and prevention actions.

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.

文摘Interfacial magnetic field structures induced by transverse electron-scale shear instability(mushroom instability)are found to be strongly associated with electron and ion dynamics,which in turn will influence the development of the instability itself.We find that high-frequency electron oscillations are excited normal to the shear interface.Also,on a larger time scale,the bulk of the ions are gradually separated under the influence of local magnetic fields,eventually reaching an equilibrium related to the initial shear conditions.Wepresent a theoretical model of this behavior.Such separation on the scale of the electron skin depth will prevent different ions from mixing and will thereafter restrain the growth of higher-order instabilities.We also analyze the role of electron thermal motion in the generation of the magnetic field,and we find an increase in the instability growth rate with increasing plasma temperature.These results have potential for providing a more realistic description of relativistic plasma flows.

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.

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.

文摘Background:The potential impact of pre-existing coronary artery stenosis(CAS)on acute pulmonary embolism(PE)episodes remains underexplored.This study aimed to investigate the association between pre-existing CAS and the elevation of high-sensitivity cardiac troponin I(hs-cTnI)levels in patients with PE.Methods:In this multicenter,prospective case-control study,88 cases and 163 controls matched for age,sex,and study center were enrolled.Cases were patients with PE with elevated hs-cTnI.Controls were patients with PE with normal hs-cTnI.Coronary artery assessment utilized coronary computed tomographic angiography or invasive coronary angiography.CAS was defined as≥50%stenosis of the lumen diameter in any coronary vessel>2.0 mm in diameter.Conditional logistic regression was used to evaluate the association between CAS and hs-cTnI elevation.Results:The percentage of CAS was higher in the case group compared to the control group(44.3%[39/88]vs.30.1%[49/163];P=0.024).In multivariable conditional logistic regression model 1,CAS(adjusted odds ratio[OR],2.680;95%confidence interval[CI],1.243-5.779),heart rate>75 beats/min(OR,2.306;95%CI,1.056-5.036)and N-terminal pro-B type natriuretic peptide(NT-proBNP)>420 pg/mL(OR,12.169;95%CI,4.792-30.900)were independently associated with elevated hs-cTnI.In model 2,right CAS(OR,3.615;95%CI,1.467-8.909)and NT-proBNP>420 pg/mL(OR,13.890;95%CI,5.288-36.484)were independently associated with elevated hs-cTnI.Conclusions:CAS was independently associated with myocardial injury in patients with PE.Vigilance towards CAS is warranted in patients with PE with elevated cardiac troponin levels.

文摘Cancer is a major public health problem and represents substantial disparities worldwide.This study reported estimates for 36 cancers across 185 countries by incidence,mortality,5-year prevalence,mortality-toprevalence ratio(MPR),and mortality-to-incidence ratio(MIR)to examine its association with human development index(HDI)and gross national income(GNI).Data were collected from the GLOBOCAN 2020.MPR and MIR were calculated by sex,age group,country,and cancer type and then summarized into totals.Segi’s population and global cancer spectrum were used to calculate age-and type-standardized ratios.Correlation analyses were conducted to assess associations.Results showed that breast cancer was the most diagnosed cancer globally.Low-and middle-income countries had high MPR and MIR.Cancers of esophagus,pancreas,and liver had the highest ratios.Males and the older population had the highest ratios.HDI and GNI were positively correlated with incidence and mortality but negatively correlated with MPR/MIR.Substantial disparities in cancer burden were observed among 36 cancer types across 185 countries.Socioeconomic development may contribute to narrowing these disparities,and tailored strategies are crucial for regional-and country-specific cancer control.

文摘Almost all the neutralizing antibodies targeting the receptor-binding domain(RBD)of spike(S)protein show weakened or lost efficacy against severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)emerged or emerging variants,such as Omicron and its sub-variants.This suggests that highly conserved epitopes are crucial for the development of neutralizing antibodies.Here,we present one nanobody,N235,displaying broad neutralization against the SARS-CoV-2 prototype and multiple variants,including the newly emerged Omicron and its sub-variants.Cryo-electron microscopy demonstrates N235 binds a novel,conserved,cryptic epitope in the N-terminal domain(NTD)of the S protein,which interferes with the RBD in the neighboring S protein.The neutralization mechanism interpreted via flow cytometry and Western blot shows that N235 appears to induce the S1 subunit shedding from the trimeric S complex.Furthermore,a nano-IgM construct(MN235),engineered by fusing N235 with the human IgM Fc region,displays prevention via inducing S1 shedding and cross-linking virus particles.Compared to N235,MN235 exhibits varied enhancement in neutralization against pseudotyped and authentic viruses in vitro.The intranasal administration of MN235 in low doses can effectively prevent the infection of Omicron sub-variant BA.1 and XBB in vivo,suggesting that it can be developed as a promising prophylactic antibody to cope with the ongoing and future infection.

文摘Background:Large disparities exist in liver cancer burden trends across countries but are poorly understood.We aimed to investigate the global trajectories of liver cancer burden,explore the driving forces,and predict future trends.Methods:Data on the liver cancer burden in 204 countries and territories from 1990 to 2019 were extracted from the Global Burden of Disease Study.The age-standardized incidence rate(ASIR)and age-standardized mortality rate(ASMR)trajectories were defined using growth mixture models.Five major risk factors contributing to changes in the ASIR or ASMR and socioeconomic determinants were explored using the identified trajectories.A Bayesian age-period-cohort model was used to predict future trends through 2035.Results:Three trajectories of liver cancer burden were identified:increasing,stable,and decreasing groups.Almost half of the American countries were classified in the decreasing group(48.6%for ASIR and ASMR),and the increasing group was the most common in the European region(ASIR,49.1%;ASMR,37.7%).In the decreasing group,the decrease of liver cancer due to hepatitis B contributed 63.4%and 60.4%of the total decreases in ASIR and ASMR,respectively.The increase of liver cancer due to alcohol use,hepatitis C,and hepatitis B contributed the most to the increase in the increasing group(30.8%,31.1%,and 24.2%for ASIR;33.7%,30.2%,and 22.2%for ASMR,respectively).The increasing group was associated with a higher sociodemographic index,gross domestic product per capita,health expenditure per capita,and universal health coverage(all P<0.05).Significant variations in disease burden are predicted to continue through 2035,with a disproportionate burden in the decreasing group.Conclusion:Global disparities were observed in liver cancer burden trajectories.Hepatitis B,alcohol use,and hepatitis C were identified as driving forces in different regions.

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.
