1Cancer burden of major cancers in China:A need for sustainable actions显示文摘Cancer is still a major health problem in China although numerous efforts have been made for its prevention and control.Findings from this study showed that lung cancer remains the most common type of cancer diagnosed,and was attributed to nearly 30%of all cancer-related deaths.The incidence of the five most common cancers,in China,in 2015,including cancers of the lungs,stomach,colorectum,liver and breast,accounted for almost 60%of all cancers diagnosed.The high cancer burden in China highlights the need for further improvement in health education,professional training and the building up an anti-cancer network for introducing and implementing sustainable actions for cancer control.Maomao Cao He Li Dianqin Sun Wanqing Chen 2020Cancer Communications2020,40,5:140
2Cancer 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
3Cancer burden and trends in China:A review and comparison with Japan and South Korea显示文摘Objective:To summarize the cancer burden and trends in China,compare the differences among China,Japan,and South Korea and discuss possible causes of the disparities.Methods:Incidence and mortality data were extracted from the online cancer database including the GLOBOCAN 2018 and the Global Burden of Disease Study 2017.Trend analysis was conducted using the joinpoint analysis,and annual percent changes were calculated.Results:Cancers resulted in approximately 62.9 million disability-adjusted life years(DALYs)in China in 2017.Lung cancer had the greatest contribution,followed by liver cancer,stomach cancer,and esophageal cancer.The trajectory of progress in the reduction of liver and stomach cancers was observed in China.However,China still faced a heavy burden of lung cancer and a growing burden of cancers related to westernized lifestyle such as colorectal cancer,while Japan and South Korea have achieved reductions in colorectal cancer and lung cancer,respectively.Besides,China had a lower age-standardized cancer incidence rate but higher cancer mortality and DALY rates than Japan and South Korea.Conclusions:China is in the cancer transition stage with a rising burden of colorectal,prostate,and breast cancers along with a heavy burden of lung and upper digestive tract cancers.Taking into consideration the effectiveness of screening and tobacco control in Japan and South Korea,improvement in the current tobacco control policy and cancer screening systems may contribute to cancer control in China.Dianqin Sun Maomao Cao He Li Siyi He Wanqing Chen 2020Chinese Journal of Cancer Research2020,32,2:71
4Cancer burden in China:trends,risk factors and prevention显示文摘As the most populous country in the world,China has made strides in health promotion in the past few decades.With the aging population,the burden of cancer in China continues to grow.Changes in risk factors for cancer,especially diet,obesity,diabetes,and air pollution,continue to fuel the shift of cancer transition in China.The burden of upper gastrointestinal cancer in China is decreasing,but still heavy.The rising burden of colorectal,prostate,and breast cancers is also significant.Lung cancer became the top cause of cancer-related deaths,together with smoking as the most important contributor to cancer deaths.The Chinese government has taken several approaches to control cancer and cancer-related risk factors.Many achievements have been made,but some challenges remain.Health China 2030 is ambitious and depicts a bright vision of the future for cancer control in China.The decrease in the cancer burden in China will require cross-sector collaboration and coordinated efforts on primary and secondary preventions by governments,public health organizations,and individuals.In this review,we describe the trends of cancer burden and discuss cancer-related risk factors in China,identifying strategies to reduce the burden of cancer in China.Dianqin Sun He Li Maomao Cao Siyi He Lin Lei Ji Peng Wanqing Chen 2020Cancer Biology & Medicine2020,17,4:62
5Current 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
6Trends and risk factors of lung cancer in China显示文摘China is faced with heavy burdens caused by lung cancer,which has climbed to the top of both cancer incidence and mortality spectrums.The age-standardized rates of incidence and mortality have shown a trend of gradual uptrends in the last decades,while the crude rates rise much quickly due to the aging of population.Although the improvement in health care has contributed to better survival of lung cancer,its prognosis is still challenging.Apart from the common risk factors such as tobacco use,air pollution,and occupational hazards,some specific factors like Chinese-style cooking also have posed great threats to human health.In light of such national conditions,specific interventions should be conducted to curb the burden of lung cancer including smoking cessation,improvement of air quality,early detection and effective treatment of lung cancer.Siyi He He Li Maomao Cao Dianqin Sun Lin Lei Ni Li Ji Peng Wanqing Chen 2020Chinese Journal of Cancer Research2020,32,6:16
7A study protocol of population-based cancer screening cohort study on esophageal,stomach and liver cancer in rural China显示文摘Objective:National Health Commission of the People's Republic of China collaborated with many ministries and commissions government and initiated a population-based cancer screening program in high-risk area of rural China,targeting three types of cancer that are most prevalent in these areas,including esophageal,stomach and liver cancer.This study protocol was reported to show the design and evaluate the effectiveness of cancer screening and appropriate screening strategies of three cancers in rural China.Methods and analysis:A two-step design with cancer risk assessment based on questionnaire interview,Hepatitis B surface antigen(HBsAg)test strip and subsequent clinical intervention for high-risk populations was adopted&ee of charge at the local hospitals designated in the program.Ethic and dissemination:This study was approved by the Institutional Review Board of Cancer Hospital,Chinese Academy of Medical Sciences and Peking Union Medical College.The results will evaluate the effectiveness of cancer screening and appropriate screening strategies in rural China.Jiang Li He Li Hongmei Zeng Rongshou Zheng Maomao Cao Dianqin Sun Jiansong Ren Wanqing Chen Jie He 2020Chinese Journal of Cancer Research2020,32,4:10
8Association of cancer prevention awareness with esophageal cancer screening participation rates: Results from a population-based cancer screening program in rural China显示文摘Objective: : China have implemented population-based esophageal cancer(EC) screening programs, however,the participant rates were relatively low. This study was conducted to examine the association between cancer prevention knowledge and EC screening participation rates(PRs).Methods: : Data in the analyses were obtained from a population-based cancer screening program in four provinces in China since 2007. In the course of 2007-2016, participants who were evaluated as high risk for EC and subsequently recommended for endoscopy examination were included in the final analysis. One-way analysis of variance test, Chi-square test and logistic regression analysis were applied.Results: : A total of 28,543 individuals assessed as high-risk population for EC were included in this study, with13,036 males(45.67%) and 15,507 females(54.33%). The prevalence rates of current smoking and alcohol drinking were higher in males(58.25% and 44.22%, respectively) than in females(5.35% and 4.05%, respectively).Participants of females, and those who had older age, lower income, as well as higher education level and cancer prevention knowledge level were more likely to undergo endoscopy. Multivariable analysis showed that higher cancer prevention knowledge was associated with higher PR for endoscopic screening [adjusted odd ratio(aORQ4/Q1) =1.511, 95% confidence interval(95% CI): 1.398-1.632] among our study subjects. This association between cancer prevention knowledge and compliance with endoscopic screening also tends to be strong within subgroups of males, females, aged below 60 years, aged 60 years and above, and lower level of education(illiterate individuals and those with junior high education or less).Conclusions: : Our results displayed a positive relationship between cancer prevention knowledge and PRs for endoscopic screening, implying cancer prevention awareness being an independent influence factor for compliance with EC screening. Promoting public campaigns about comprehensive knowledge of cancer prevention seemed to be a reasonable and effective strategy to improve population PRs for EC screening.Shangchun Jia He Li Hongmei Zeng Rongshou Zheng Jiang Li Jufang Shi Zhixun Yang Maomao Cao Wanqing Chen 2019Chinese Journal of Cancer Research2019,31,4:10
9Preliminary analysis on the source properties and seismogenic structure of the 2017 M_s7.0 Jiuzhaigou earthquake显示文摘At GMT time 13:19, August 8, 2017, an Ms7.0 earthquake struck the Jiuzhaigou region in Sichuan Province, China,causing severe damages and casualties. To investigate the source properties, seismogenic structures, and seismic hazards, we systematically analyzed the tectonic environment, crustal velocity structure in the source region, source parameters and rupture process, Coulomb failure stress changes, and 3-D features of the rupture plane of the Jiuzhaigou earthquake. Our results indicate the following:(1) The Jiuzhaigou earthquake occurred on an unmarked fault belonging to the transition zone of the east Kunlun fault system and is located northwest of the Huya fault.(2) Both the mainshock and aftershock rupture zones are located in a region where crustal seismic velocity changes dramatically. Southeast to the source region, shear wave velocity at the middle to lower crust is significantly low, but it rapidly increases northeastward and lies close to the background velocity across the rupture fault.(3) The aftershock zone is narrow and distributes along the northwest-southeast trend, and most aftershocks occur within a depth range of 5–20 km.(4) The focal mechanism of the Jiuzhaigou earthquake indicates a left-lateral strike-slip fault, with strike, dip, and rake angles of 152°, 74° and 8°, respectively. The hypocenter depth measures 20 km, whereas the centroid depth is about 6 km. The co-seismic rupture mainly concentrates at depths of 3–13 km, with a moment magnitude(M_w) of 6.5.(5) The co-seismic rupture also strengthens the Coulomb failure stress at the two ends of the rupture fault and the east segment of the Tazang fault. Aftershocks relocation results together with geological surveys indicate that the causative fault is a near vertical fault with notable spatial variations: dip angle varies within 66°–89° from northwest to southeast and the average dip angle measures ~84°. The results of this work are of fundamental importance for further studies on the source characteristics, tectonic environment, and seismic hazard evaluation of the Jiuzhaigou earthquake.Zujun XIE Yong ZHENG Huajian YAO Lihua FANG Yong ZHANG Chengli LIU Maomao WANG Bin SHAN Huiping ZHANG Junjie REN Lingyun JI Meiqin SONG 2018Science China Earth Sciences2018,61,3:8
10No expenditure difference among patients with liver cancer at stageⅠ-ⅣV:Findings from a multicenter cross-sectional study in China显示文摘Objective:The number of liver cancer patients in China accounts for more than half of the world.However,China currently lacks national,multicenter economic burden data,and meanwhile,measuring the differences among different subgroups will be informative to formulate corresponding policies in liver cancer control.Thus,the aim of the study was to measure the economic burden of liver cancer by various subgroups.Methods:A hospital-based,multicenter and cross-sectional survey was conducted during 2012・2014,covering 39 hospitals and 21 project sites in 13 provinces across China.The questionnaire covers clinical information,sociology,expenditure,and related variables.All expenditure data were reported in Chinese Yuan(CNY)using 2014 values.Results:A total of 2,223 liver cancer patients were enrolled,of whom 59.61%were late-stage cases(III-IV),and 53.8%were hepatocellular carcinoma.The average total expenditure per liver cancer patient was estimated as 53,220 CNY,including 48,612 CNY of medical expenditures(91.3%)and 4,608 CNY of non-medical expenditures(8.7%).The average total expenditures in stage I,H,m and stage IV were 52,817 CNY,50,877 CNY,50,678 CNY and 54,089 CNY(P>0.05),respectively.Non-medical expenditures including additional meals,additional nutrition care,transportation,accommodation and hired informal nursing were 1,453 CNY,839 CNY,946 CNY,679 CNY and 200 CNY,respectively.The one-year out-of-pocket expenditure of a newly diagnosed patient was 24,953 CNY,and 77.2%of the patients suffered an unmanageable financial burden.Multivariate analysis showed that overall expenditure differed in almost all subgroups(P<0.05),except for sex,clinical stage,and pathologic type.Conclusions:There was no difference in treatment expenditure for liver cancer patients at different clinical stages,which suggests that maintaining efforts on treatment efficacy improvement is important but not enough.To fiirtherly reduce the overall economic burden from liver cancer,more effort should be given to primary and secondary prevention strategies.Haike Lei Lin Lei Jufang Shi Yongzhong Wu Ling Liang Huiyao Huang Mei He Fangzhou Bai Maomao Cao Hui Qiu Yuting Wang Chengcheng Liu Jia Du Hong Wang Yan Zhang Mengdi Cao Ji Peng Ni Li Chunfeng Qu Min Dai Wanqing Chen Jie He 2020Chinese Journal of Cancer Research2020,32,4:7
11Colorectal 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
12The Risk and Prevention of Novel Coronavirus Pneumonia Infections Among Inpatients in Psychiatric Hospitals显示文摘Dear Editor,Since the middle of December 2019,human-to-human transmission of novel coronavirus pneumonia(NCP,also called COVID-19)has occurred among close contacts[1].After the outbreak on January 21,2020,it was swiftly included among the Class B infectious diseases stipulated in the Law of the People’s Republic of China on the Prevention and Control of Infectious Diseases,and measures for prevention and control of Class A infectious diseases were adopted.At 21:27 on February 12,2020,the China News Network updated information to include epidemic data from the National Health Commission and official channels in Hong Kong,Macao,and Taiwan regions:the highest death rate was in Wuhan City(Table 1).Overload of inpatients at hospitals may play a negative role in the overall therapeutic effect and contribute to the death rate.Yuncheng Zhu Liangliang Chen Haifeng Ji Maomao Xi Yiru Fang Yi Li 2020Neuroscience Bulletin2020,36,3:6
13Attributable deaths of liver cancer in China显示文摘Objective:There is little information about contributions of the well-known risk factors to the liver cancer burden.We conducted a comparative study to estimate the liver cancer burden attributable to major risk factors.Methods:Liver cancer deaths for adults were estimated from 978 county-level surveillance points in China in2014.Risk factors were identified from the International Agency for Research on Cancer and the World Cancer Research Fund International.Population attributable fraction(PAF)by age,sex,and province was calculated using multiple formulas.Results:In total,72.4%of liver cancer deaths could be attributable to the studied risk factors.Hepatitis B virus(HBV)was responsible for the largest fraction of liver cancer burden in both genders(PAF=55.6%in males,PAF=46.5%in females).PAFs for liver cancer burden attributable to smoking(15.7%vs.4.8%),and alcohol drinking(10.3%vs.1.6%)were significantly higher in males than in females.The burden of HBV-attributable deaths was the highest in Qinghai province.Conclusions:HBV still contributes to the majority of liver cancer burden than any other risk factors.Targeted preventive measures should be implemented based on the degree of contributions of risk factors to liver cancer deaths.Maomao Cao Chao Ding Changfa Xia He Li Dianqin Sun Siyi He Wanqing Chen 2021Chinese Journal of Cancer Research2021,33,4:6
14Classifying risk level of gastric cancer: Evaluation of questionnaire-based prediction model显示文摘Objective: This study aimed at evaluating the efficacy of the questionnaire-based prediction model in an independent prospective cohort.Methods: A cluster-randomized controlled trial was conducted in Changsha, Harbin, Luoshan, and Sheyang in eastern China in 2015-2017. A total of 182 villages/communities were regarded as clusters, and allocated to screening arm or control arm randomly. Face-to-face interview through a questionnaire interview, including of relevant risk factors of gastric cancer, was administered for each subject. Participants were further classified into high-risk or low-risk groups based on their exposure to risk factors. All participants were followed up until December 31, 2019. Cumulative incidence rates from gastric cancer between high-risk and low-risk groups were calculated and compared using the log-rank test. Cox proportional hazard regression models were applied to estimate hazard ratio(HR) and 95% confidence interval(95% CI).Results: Totally, 89,914 residents were recruited with a mean follow-up of 3.47 years. And 42,015(46.73%)individuals were classified into high-risk group and 47,899(53.27%) subjects were categorized into low-risk group.Gastric cancer was diagnosed in 131 participants, of which 91 were in high-risk group. Compared with the low-risk participants, high-risk individuals were more likely to develop gastric cancer(adjusted HR=2.15, 95% CI,1.23-3.76). The sensitivity of the questionnaire-based model was estimated at 61.82%(95% CI, 47.71-74.28) in a general population.Conclusions: Our questionnaire-based model is effective at identifying high-risk individuals for gastric cancer.Maomao Cao He Li Dianqin Sun Lin Lei Jiansong Ren Jufang Shi Ni Li Ji Peng Wanqing Chen 2020Chinese Journal of Cancer Research2020,32,5:5
15Improved esophageal squamous cell carcinoma screening effectiveness by risk-stratified endoscopic screening:evidence from high-risk areas in China显示文摘Background:Risk-stratified endoscopic screening(RSES),which offers endoscopy to those with a high risk of esophageal cancer,has the potential to increase effectiveness and reduce endoscopic demands compared with the universal screening strategy(i.e.,endoscopic screening for all targets without risk prediction).Evidence of RSES in high-risk areas of China is limited.This study aimed to estimate whether RSES based on a 22-score esophageal squamous cell carcinoma(ESCC)risk prediction model could optimize the universal endoscopic screening strategy for ESCC screening in high-risk areas of China.Methods:Eight epidemiological variables in the ESCC risk prediction model were collected retrospectively from 26,618 individuals aged 40-69 from three high-risk areas of China who underwent endoscopic screening betweenMay 2015 and July 2017.The model’s performance was estimated using the area under the curve(AUC).Participants were categorized into a high-risk group and a low-risk group with a cutoff score having sensitivities of both ESCC and severe dysplasia and above(SDA)at more than 90.0%.Results:The ESCC risk prediction model had an AUC of 0.80(95% confidence interval:0.75-0.84)in this external population.We found that a score of 8(ranging from 0 to 22)had a sensitivity of 94.2% for ESCC and 92.5% for SDA.The RSES strategy using this threshold score would allow 50.6% of endoscopies to be avoided and save approximately US$0.59 million compared to universal endoscopic screening among 26,618 participants.In addition,a higher prevalence of SDA(1.7%vs.0.9%),a lower number need to screen(60 vs.111),and a lower average cost per detected SDA(US$3.22 thousand vs.US$5.45 thousand)could have been obtained by the RSES strategy.Conclusions:The RSES strategy based on individual risk has the potential to optimize the universal endoscopic screening strategy in ESCC high-risk areas of China.He Li Chao Ding Hongmei Zeng Rongshou Zheng Maomao Cao Jiansong Ren Jufang Shi Dianqin Sun Siyi He Zhixun Yang Yiwen Yu Zhe Zhang Xibin Sun Guizhou Guo Guohui Song Wenqiang Wei Wanqing Chen Jie He 2021Cancer Communications2021,41,8:3
16Planning and Design of Settlement Based on Rural Landscapes:A Case Study of Fenshui Village, Dazhou City of China显示文摘Landscape planning and design of settlements in Fenshui Village, Dazhu County, Dazhou City of Sichuan Province was taken for example, specifically, Tudibao Settlement, Gouyaonaoke Settlement and Bianyaqi Settlement, to analyze their location advantages and restrictions. On this basis, planning support for rural areas in east Sichuan Province was proposed, integrality of the settlement, landscape diversity, landscape integration and sharing were highlighted. It was proposed that local landscape planning should follow the principle of 'human- land coordination', protect and inherit folk cultures of east Sichuan, pay attention to physical and spiritual needs of the locals. Core contents of rural landscape planning and design in east Sichuan were summarized, utilization of natural landscapes in the ecological design and sustainable development of landscapes were stressed.ZHOU Yunting YANG Maomao SHI Jin'an 2012Journal of Landscape Research2012,4,8:3
17Development of an ANN-based building energy model for information-poor buildings using transfer learning显示文摘Accurate building energy prediction is vital to develop optimal control strategies to enhance building energy efficiency and energy flexibility.In recent years,the data-driven approach based on machine learning algorithms has been widely adopted for building energy prediction due to the availability of massive data in building automation systems(BASs),which automatically collect and store real-time building operational data.For new buildings and most existing buildings without installing advanced BASs,there is a lack of sufficient data to train data-driven predictive models.Transfer learning is a promising method to develop accurate and reliable data-driven building energy prediction models with limited training data by taking advantage of the rich data/knowledge obtained from other buildings.Few studies focused on the influences of source building datasets,pre-training data volume,and training data volume on the performance of the transfer learning method.The present study aims to develop a transfer learning-based ANN model for one-hour ahead building energy prediction to fill this research gap.Around 400 non-residential buildings’data from the open-source Building Genome Project are used to test the proposed method.Extensive analysis demonstrates that transfer learning can effectively improve the accuracy of BPNN-based building energy models for information-poor buildings with very limited training data.The most influential building features which influence the effectiveness of transfer learning are found to be building usage and industry.The research outcomes can provide guidance for implementation of transfer learning,especially in selecting appropriate source buildings and datasets for developing accurate building energy prediction models.Ao Li Fu Xiao Cheng Fan Maomao Hu 2021Building Simulation2021,14,1:3
18Stomach 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
19Phase Transformation Strengthening of Hot Extruded Inconel 625 under High-temperature Load Environment显示文摘Microstructure evolution and properties of hot-extruded Inconel 625 alloy were investigated at different creep temperatures, aging time and strain rates. The experimental results indicate that the Inconel 625 alloy exhibits an excellent creep resistance at 700 ℃ and below. When the creep temperature rises to 750 ℃, the creep resistance falls drastically due to the failure of phase transformation strengthening and the precipitation of a large amount of δ phase and σ phase at the grain boundary. The special temperature-sensitive characteristics of Inconel 625 alloy play a very important role in its fracture. When the strain rate is 8.33×10^-3s^-1, the strength of the specimen is higher than that of other parameters attributed to the effect of phase transformation strengthening. With the increase of Ni3(Al, Ti), the phase transformation strengthening inhibits thickening of the stacking faults into twins and improves the overall mechanical properties of the alloy. With the increase of the aging time, the granular Cr-rich M23C6 carbides continue to precipitate at the grain boundary, which hinders the movement of the dislocations and obviously increases the strength of the samples. Especially, the yield strength increases several times.刘德学 CUI Maomao 王文旭 NAN Hongqiang CAI Haopeng XUE Hongdi JIA Zhi LI Qinglin 2019Journal of Wuhan University of Technology(Materials Science)2019,34,6:2
20Burden 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
