| 1 | Liver 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 | 2018 | Chinese Journal of Cancer Research2018，30，6： | 132 |
| 2 | Cancer 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 | 2018 | Chinese Journal of Cancer Research2018，30，1： | 832 |
| 3 | Breast cancer incidence and mortality in women in China: temporal trends and projections to 2030显示文摘Objective:Breast cancer was the most common cancer and the fifth cause of cancer deaths among women in China in 2015.The evaluation of the long-term incidence and mortality trends and the prediction of the future burden of breast cancer could provide valuable information for developing prevention and control strategies.Methods:The burden of breast cancer in China in 2015 was estimated by using qualified data from 368 cancer registries from the National Central Cancer Registry.Incident cases and deaths in 22 cancer registries were used to assess the time trends from 2000 to 2015.A Bayesian age-period-cohort model was used to project the burden of breast cancer to 2030.Results:Approximately 303,600 new cases of breast cancer(205,100 from urban areas and 98,500 from rural areas)and 70,400 breast cancer deaths(45,100 from urban areas and 24,500 from rural areas)occurred in China in 2015.Urban regions of China had the highest incidence and mortality rates.The most common histological subtype of breast cancer was invasive ductal carcinoma,followed by invasive lobular carcinoma.The age-standardized incidence and mortality rates increased by 3.3%and 1.0%per year during 2000–2015,and were projected to increase by more than 11%until 2030.Changes in risk and demographic factors between 2015 and 2030 in cases are predicted to increase by approximately 13.3%and 22.9%,whereas deaths are predicted to increase by 13.1%and 40.9%,respectively.Conclusions:The incidence and mortality of breast cancer continue to increase in China.There are no signs that this trend will stop by 2030,particularly in rural areas.Effective breast cancer prevention strategies are therefore urgently needed in China. | Shaoyuan Lei Rongshou Zheng Siwei Zhang Ru Chen Shaoming Wang Kexin Sun Hongmei Zeng Wenqiang Wei Jie He | 2021 | Cancer Biology & Medicine2021，18，3： | 53 |
| 4 | Global patterns of breast cancer incidence and mortality:A population-based cancer registry data analysis from 2000 to 2020显示文摘Background:Breast cancer is the most commonly diagnosed cancer and leading cause of cancer death among women worldwide but has patterns and trends which vary in different countries.This study aimed to evaluate the global patterns of breast cancer incidence and mortality and analyze its temporal trends for breast cancer prevention and control.Methods:Breast cancer incidence and mortality data in 2020 were obtained from the GLOBOCAN online database.Continued data from the Cancer Incidence in Five Continents Time Trends,the International Agency for Research on cancer mortality and China National Central Cancer Registry were used to analyze the time trends from 2000 to 2015 through Joinpoint regression,and annual average percent changes of breast cancer incidence and mortality were calculated.Association between Human Development Index and breast cancer incidence and mortality were estimated by linear regression.Results:There were approximately 2.3 million new breast cancer cases and 685,000 breast cancer deaths worldwide in 2020.Its incidence and mortality varied among countries,with the age-standardized incidence ranging from the highest of 112.3 per 100,000 population in Belgium to the lowest of 35.8 per 100,000 population in Iran,and the age-standardized mortality from the highest of 41.0 per 100,000 population in Fiji to the lowest of 6.4 per 100,000 population in South Korea.The peak age of breast cancer in some Asian and African countries were over 10 years earlier than in European or American countries.As for the trends of breast cancer,the age-standardized incidence rates significantly increased in China and South Korea but decreased in the United States of America(USA)during 2000-2012.Meanwhile,the age-standardized mortality rates significantly increased in China and South Korea but decreased in the United Kingdom,the USA,and Australia during 2000 and 2015.Conclusions:The global burden of breast cancer is rising fast and varies greatly among countries.The incidence and mortality rates of breast cancer increased rapidly in China and South Korea but decreased in the USA.Increased health awareness,effective prevention strategies,and improved access to medical treatment are extremely important to curb the snowballing breast cancer burden,especially in the most affected countries. | Shaoyuan Lei Rongshou Zheng Siwei Zhang Shaoming Wang Ru Chen Kexin Sun Hongmei Zeng Jiachen Zhou Wenqiang Wei | 2021 | Cancer Communications2021，41，11： | 55 |
| 5 | Annual cost of illness of stomach and esophageal cancer patientsin urban and rural areas in China: A multi-center study显示文摘Objective: Stomach and esophageal cancer are imposing huge threats to the health of Chinese people whereas there were few studies on the financial burden of the two cancers.Methods: Costs per hospitalization of all patients with stomach or esophageal cancer discharged between September 2015 and August 2016 in seven cities/counties in China were collected, together with their demographic information and clinical details. Former patients in the same hospitals were sampled to collect information on annual direct non-medical cost, indirect costs and annual number of hospitalization. Annual direct medical cost was obtained by multiplying cost per hospitalization by annual number of hospitalization. Annual cost of illness(ACI)was obtained by adding the average value of annual direct medical cost, direct non-medical cost and indirect cost,stratified by sex, age, clinical stage, therapy and pathologic type in urban and rural areas. Costs per hospitalization were itemized into eight parts to calculate the proportion of each part. All costs were converted to 2016 US dollars(1 USD=6.6423 RMB).Results: Totally 19,986 cases were included, predominately male. Mean ages of stomach cancer and urban patients were lower than that of esophageal cancer and rural patients. ACI of stomach and esophageal cancer patients were $10,449 and $13,029 in urban areas, and $2,927 and $3,504 in rural areas, respectively. Greater ACI was associated with male, non-elderly patients as well as those who were in stage I and underwent surgeries.Western medicine fee took the largest proportion of cost per hospitalization.Conclusions: The ACI of stomach and esophageal cancer was tremendous and varied substantially among the population in China. Preferential policies of medical insurance should be designed to tackle with this burden and further reduce the health care inequalities. | Zhixun Yang Hongmei Zeng Ruyi Xia Qian Liu Kexin Sun Rongshou Zheng Siwei Zhang Changfa Xia He Li Shuzheng Liu Zhiyi Zhang Yuqin Liu Guizhou Guo Guohui Song Yigong Zhu Xianghong Wu Bingbing Song Xianzhen Liao Yanfang Chen Wenqiang Wei Guihua Zhuang Wanqing Chen | 2018 | Chinese Journal of Cancer Research2018，30，4： | 22 |
| 6 | Colorectal cancer burden and trends:Comparison between China and major burden countries in the world显示文摘Objective:To summarize the colorectal cancer(CRC)burden and trend in the world,and compare the difference of CRC burden between other countries and China.Methods:Incidence and mortality data were extracted from the GLOBOCAN2018 and Cancer Incidence in Five Continents.Age-specific incidence trend was conducted by Joinpoint analysis and average annual percent changes were calculated.Results:About 1.85 million new cases and 0.88 million deaths were expected in 2018 worldwide,including 0.52 million(28.20%)new cases and 0.25 million(28.11%)deaths in China.Hungary had the highest age-standardized incidence and mortality rates in the world,while for China,the incidence and mortality rates were only half of that.CRC incidence and mortality were highly correlated with human development index(HDI).Unlike the rapid increase in Republic of Korea and the downward trend in Canada and Australia,the age-standardized incidence rates by world standard population in China and Norway were rising gradually.The age-specific incidence rate in the age group of 50-59 years in China was increasing rapidly,while in Republic of Korea and Canada,the fastest growing age group was 30-39 years.Conclusions:The variations of CRC burden reflect the difference of risk factors,as well as levels of HDI and screening(early detection activities).The burden of CRC in China is high,and the incidence of CRC continues to increase,which may lead to a sustained increase in the burden of CRC in China in the future.Screening should be expanded to control CRC,and focused on young people in China. | Jiachen Zhou Rongshou Zheng Siwei Zhang Hongmei Zeng Shaoming Wang Ru Chen Kexin Sun Minjuan Li Jianhua Gu Guihua Zhuang Wenqiang Wei | 2021 | Chinese Journal of Cancer Research2021，33，1： | 16 |
| 7 | Cancer statistics in Chinese older people,2022:current burden,time trends,and comparisons with the US,Japan,and the Republic of Korea显示文摘Largely due to population ageing,the cancer burden from older people has been rising,which imposed considerable pressure on current Chinese healthcare system.We provide comprehensive information about cancer burden of Chinese older people based on the most recent data from National Central Cancer Registry of China.The logarithmic linear regression was used to project the current cancer burden in 2022,and Joinpoint regression was used for temporal trend analysis from 2000 to 2017.We also estimated cancer statistics of older people in the US,Japan and the Republic of Korea for comparisons.It is estimated that 2.79 million cases and 1.94 million deaths occur for Chinese older people,representing 55.8%and 68.2%of cases and deaths in all population in 2022.The overall cancer incidence rate gradually increased among older women,while the mortality rates declined for both sexes.Notably,approximately 10.0%of all cases and 17.7%of all deaths are from people aged over 80 years,and cancer incidence and mortality in this age group showed upward trends for women.Lung cancer and digestive cancers are the leading cancer types for Chinese older people.Compared with other countries,China has lower incidence rates but higher mortality rates for older people.The rapidly growing burden of prostate cancer,breast cancer,colorectal cancer,and declines in esophageal cancer,stomach cancer,and liver cancer among older people indicate the cancer pattern in China is being in a transition stage to that in developed countries.Our findings imply that it should be the national health priority to meet the growing demands for cancer diagnosis,treatment and care services from the older people as the rapid population ageing in next few decades. | Wen Ju Rongshou Zheng Siwei Zhang Hongmei Zeng Kexin Sun Shaoming Wang Ru Chen Li Li Wenqiang Wei Jie He | 2023 | Science China(Life Sciences)2023，66，5： | 15 |
| 8 | The epidemiology of colorectal cancer in China显示文摘Objective:Colorectal cancer(CRC)is one of the most common cancers and the major cause of cancer death in China.The aim of this study was to estimate the burden of CRC in China.Materials and methods:Data from the National Cancer Center(NCC)of China was used and stratified by area(urban/rural),sex(male/female)for analyzing the age-speci c incidence and mortality rates.Time trend of colorectal cancer was calculated based on the 22 high-quality cancer registries in China.National new cases and deaths of colorectal cancer were estimated using age-speci c rates multiplied by the corresponding national population in 2014.The Chinese population in 2000 and Segi’s world population were used to calculate age-standardized rates of colorectal cancer in China.Results:Overall,370,400 new colorectal cancer cases and 179,600 deaths were estimated in China in 2014,with about 214,100 new cases in men and 156,300 in women.Meanwhile,104,000 deaths cases of colorectal cancer were men and 75,600 deaths were women,which accounted for 9.74%and 7.82%of all cancer incidence and deaths in China,separately.Relatively higher incidence and mortality was observed in urban areas of China.And the Eastern areas of China showed the highest incidence and mortality.The age-standardized incidence and mortality rate of colorectal cancer has increased by about 1.9%per year for incidence and about 0.9%per year for mortality rate from 2000 to 2014.Conclusion:With gradually higher incidence and mortality rate in the past 15 years,colorectal cancer became a major challenge to China’s public health.E ective control strategies are needed in China. | Rongshou Zheng Hongmei Zeng Siwei Zhang Xiuying Gu Kexin Sun Changfa Xia Zhixun Yang He Li Wanqing Chen | 2018 | Global Health Journal2018，2，3： | 12 |
| 9 | The 2020/21 Extremely Cold Winter in China Influenced by the Synergistic Effect of La Niña and Warm Arctic显示文摘In the first half of winter 2020/21,China has experienced an extremely cold period across both northern and southern regions,with record-breaking low temperatures set in many stations of China.Meanwhile,a moderate La Niña event which exceeded both oceanic and atmospheric thresholds began in August 2020 and in a few months developed into its mature phase,just prior to the 2020/21 winter.In this report,the mid−high-latitude large-scale atmospheric circulation anomalies in the Northern Hemisphere,which were forced by the negative phase of Arctic Oscillation,a strengthened Siberian High,an intensified Ural High and a deepened East Asian Trough,are considered to be the direct reason for the frequent cold surges in winter 2020/21.At the same time,the synergistic effect of the warm Arctic and the cold tropical Pacific(La Niña)provided an indispensable background,at a hemispheric scale,to intensify the atmospheric circulation anomalies in middle-to-high latitudes.In the end,a most recent La Niña prediction is provided and the on-coming evolution of climate is discussed for the remaining part of the 2020/21 winter for the purpose of future decision-making and early warning. | Fei ZHENG Yuan YUAN Yihui DING Kexin LI Xianghui FANG Yuheng ZHAO Yue SUN Jiang ZHU Zongjian KE Ji WANG Xiaolong JIA | 2022 | Advances in Atmospheric Sciences2022，39，4： | 7 |
| 10 | MOF-derived Co-MOF,O-doped carbon as trifunctional electrocatalysts to enable highly efficient Zn-air batteries and water-splitting显示文摘Development of high-efficiency non-noble electrocatalysts for oxygen reduction reaction(ORR),oxygen evolution reaction(OER)and hydrogen evolution reaction(HER)is urgently needed for high-performance Zn-air batteries and overall water splitting.Here,a facile strategy to synthesize novel Co-MOF,O-doped carbon(Co-MOF-T)based on Zn,Co-doped glucosamine and ZIF-8 by pyrolysis at temperature T was demonstrated.The prepared Co-MOF-800 showed a superior oxygen reduction reaction(ORR)activity comparable to that of commercial Pt/C catalyst.In addition,this catalyst shows great potential in the overall water splitting due to the excellent oxygen evolution reaction(OER)and hydrogen evolution reaction(HER)activities.Based on the trifunctional activity,the primary Zn-air batteries using a Co-MOF-800 air electrode achieved a high open-circuit voltage of 1.38 V,a specific capacity of 671.6 mAh g^(-1) Zn,and a prominent peak power density of 144 mW cm^(-2).Also,the rechargeable Zn-air batteries based on CoMOF-800 air electrode could be smoothly run for 510 cycles with a low voltage gap of 0.58 V.Finally,the trifunctional Co-MOF-800 catalyst was applied to boost the electrochemical water splitting,demonstrating its promising potential as a green energy material for practical applications. | Xinde Duan Na Pan Can Sun Kexin Zhang Xukun Zhu Mingdao Zhang Li Song Hegen Zheng | 2021 | Journal of Energy Chemistry2021，30，5： | 5 |
| 11 | ^(10)Be/~7Be implies the contribution of stratosphere-troposphere transport to the winter-spring surface O_3 variation observed on the Tibetan Plateau显示文摘10Be/7Be is a stratospheric sensitive tracer.In this paper,measurements of 10Be/7Be and surface O3 from October 2005 to May 2006 at Mt.Waliguan (hereafter WLG,100.898°E,39.287°N,3810 m,a.s.l.),China global atmospheric watch (GAW) observatory,are introduced and used to investigate the stratosphere-troposphere transport (STT) and its impact on surface O3 on the Tibetan Plateau.The results show that the magnitude of STT is weak in winter,followed by strengthening from the end of winter to the middle of spring (from mid February to mid April) with large increases in 10Be,7Be,10Be/7Be and surface O3.At the end of spring (from the end of April to mid May in this paper),the STT weakened,and the continuous increase of surface O3 at WLG is produced by tropospheric photochemistry reactions. | ZHENG XiangDong SHEN ChengDe WAN GuoJiang LIU KeXin TANG Jie XU XiaoBin | 2011 | Chinese Science Bulletin2011，56，1： | 5 |
| 12 | Trends in Incidence Rates,Mortality Rates,and Age-Period-Cohort Effects of Cervical Cancer—China,2003–2017显示文摘Introduction:This study reported the trends and analyzed the age-period-cohort effects on the incidence and mortality rates of cervical cancer in China.Methods:The age-standardized incidence rate(ASIR)and mortality rate(ASMR)by Segi’s world standard population were calculated using qualified consecutive data from 22 cancer registries from 2003 to 2017 in China.We performed joinpoint analysis to describe the trends and age-period-cohort analysis to estimate the independent effects of age,period and cohort on trends in incidence and mortality rates of cervical cancer.Results:The ASIR and ASMR for cervical cancer in females over 20 years old increased during 2003−2017.For females<50 years,a decreasing trend in ASIR and a stable trend in ASMR were observed in urban areas after 2009.But the ASIR and ASMR kept increasing in rural areas during the whole period.For females>50 years,the ASIR and ASMR increased both in urban and rural areas.Age-period-cohort analysis showed increasing period effects on cervical cancer incidence and mortality during the whole period.The cohort effects exhibited a downward-upwarddownward pattern for the incidence(1918–1938,1938–1963,1963–1993)and mortality rates(1918–1943,1943–1963,1963–1993)in urban areas,a fluctuating pattern for incidence rate and a continuing downward pattern for mortality rate(1918–1993)in rural areas.Conclusions:The increases in cervical cancer incidence and mortality rates can be mostly explained by period effects.We observed decreases in risk for cervical cancer incidence and mortality in young female generations,which were more obvious in urban areas. | Kexin Sun Rongshou Zheng Lin Lei Siwei Zhang Hongmei Zeng Shaoming Wang Li Li Ru Chen Bingfeng Han Ji Peng Wenqiang Wei Jie He | 2022 | China CDC weekly2022，4，48： | 4 |
| 13 | Hepatocellular carcinoma and intrahepatic cholangiocarcinoma incidence between 2006 and 2015 in China: estimates based on data from 188 population-based cancer registries显示文摘Background:Hepatocellular carcinoma(HCC)and intrahepatic cholangiocarcinoma(ICC)are the most common subtypes of primary liver cancer,but nationwide incidence of both liver cancer subtypes have never been reported in China.We aimed to estimate the most recent incidence of HCC and ICC and temporal trends in China based on the most updated data from high qualified population-based cancer registries(covering 13.1%of the national population),in comparison to those in the United States at the same period.Methods:We used data from 188 Chinese population-based cancer registries covering 180.6 million population of China to estimate the nationwide incidence of HCC and ICC in 2015.And 22 population-based cancer registries’data were used to estimate the trends of HCC and ICC incidence from 2006 to 2015.Multiple imputation by chained equations method was used to impute liver cancer cases with unknown subtype(50.8%).We used data from 18 population-based registries from the Surveillance,Epidemiology,and End Results program to analyze incidence of HCC and ICC in the United States.Results:In China,an estimated 301,500 and 61,900 newly diagnosed HCC and ICC occurred in 2015.The overall age-standardized rates(ASRs)of HCC incidence decreased by 3.9%per year.For ICC incidence,the overall ASR was relatively stable,but increased in the population of over 65 years old.Subgroup analysis by age showed that the ASR of HCC incidence had the sharpest decline in population who were less than 14 years old and received neonatally hepatitis B virus(HBV)vaccination.In the United States,though the incidence of HCC and ICC were lower than those in China,the overall HCC and ICC incidence increased by 3.3%and 9.2%per year.Conclusions:China still faces with a heavy burden of liver cancer incidence.Our results may further support the beneficial effect of Hepatitis B vaccination on reduction of HCC incidence.Both healthy lifestyle promotion and infection control are needed for future liver cancer control and prevention for China and the United States. | Lan An Rongshou Zheng Siwei Zhang Ru Chen Shaoming Wang Kexin Sun Lingeng Lu Xuehong Zhang Hong Zhao Hongmei Zeng Wenqiang Wei Jie He | 2023 | Hepatobiliary Surgery and Nutrition2023，12，1： | 4 |
| 14 | Visual detection of tropomyosin,a major shrimp allergenic protein using gold nanoparticles(AuNPs)-assisted colorimetric aptasensor显示文摘A gold nanoparticle-based label-free colorimetric assay was developed to detect the shrimp allergenic protein tropomyosin(TM),an important biomarker responsible for severe clinical reactivity to shellfish.In a gold nanoparticles(AuNPs)-tropomyosin-binding aptamer(TMBA)complex,the aptamer adsorbs onto the surface of AuNPs and dissociates in the presence of TM.In addition,AuNPs tend to aggregate in the presence of ionic salt,revealing a color change(i.e.,wine-red to purple/blue)with a shift in the maximum absorption peak from 520 nm.In the presence of specific binding TM,the aptamer folds into a tertiary structure where it more efficiently stabilizes AuNPs toward the salt-induced aggregation with a hypsochromic shift in the absorption spectra compared to the stabilized AuNPs by aptamer alone.Based on the aggregation and sensitive spectral transformation principle,the AuNPs-based colorimetric aptasensor was successfully applied to detect TM with a range of 10-200 nmol/L and a low detection limit of 40 nmol/L in water samples.The reliability,selectivity,and sensitivity of the aptasensor was then tested with food samples spiked with TM.The observed detection limit was as low as 70 nmol/L in shrimp,90 nmol/L in tofu,and 80 nmol/L in eggs,respectively.We anticipate the proposed AuNPs-based colorimetric aptasensor assay possesses a high potential for the easy and efficient visual colorimetric detection of TM. | Tushar Ramesh Pavase Hong Lin Maqsood Ahmed Soomro Hongwei Zheng Xiaxia Li Kexin Wang Zhenxing Li | 2021 | Marine Life Science & Technology2021，3，3： | 3 |
| 15 | MOFs fertilized transition-metallic single-atom electrocatalysts for highly-efficient oxygen reduction: Spreading the synthesis strategies and advanced identification显示文摘Metal-organic frameworks(MOFs) have been widely used in oxygen reduction reaction(ORR) of fuel cells and metal-air batteries, attributed to their unique structures and compositions. Recently, the preparation of transition-metallic single-atom electrocatalysts(TM-SACs) using MOFs as precursors or templates has made great progress. Herein, the development history of SACs prepared based on MOFs and their characterization are overviewed firstly, and then several strategies are summarized for preparing TM-SACs using MOFs and further modification. Finally, the challenges and opportunities confronted by TM-SACs are fully discussed. Consequently, our work can guide the realization of TM-SACs abundant with high activity, high loading and high stability. | Kexin Song Yu Feng Wei Zhang Weitao Zheng | 2022 | Journal of Energy Chemistry2022，31，4： | 2 |
| 16 | METTL3-mediated m^(6)A RNA methylation regulates dorsal lingual epithelium homeostasis显示文摘The dorsal lingual epithelium,which is composed of taste buds and keratinocytes differentiated from K14^(+)basal cells,discriminates taste compounds and maintains the epithelial barrier.N6-methyladenosine(m^(6)A)is the most abundant mRNA modification in eukaryotic cells.How METTL3-mediated m^(6)A modification regulates K14^(+)basal cell fate during dorsal lingual epithelium formation and regeneration remains unclear.Here we show knockout of Mettl3 in K14^(+)cells reduced the taste buds and enhanced keratinocytes.Deletion of Mettl3 led to increased basal cell proliferation and decreased cell division in taste buds.Conditional Mettl3 knock-in mice showed little impact on taste buds or keratinization,but displayed increased proliferation of cells around taste buds in a protective manner during post-irradiation recovery.Mechanically,we revealed that the most frequent m^(6)A modifications were enriched in Hippo and Wnt signaling,and specific peaks were observed near the stop codons of Lats1 and FZD7.Our study elucidates that METTL3 is essential for taste bud formation and could promote the quantity recovery of taste bud after radiation. | Qiuchan Xiong Caojie Liu Xin Zheng Xinyi Zhou Kexin Lei Xiaohan Zhang Qian Wang Weimin Lin Ruizhan Tong Ruoshi Xu Quan Yuan | 2022 | International Journal of Oral Science2022，14，3： | 2 |
| 17 | More Detailed Disturbance Measurement and Active Disturbance Rejection Altitude Control for a Flapping Wing Robot Under Internal and External Disturbances显示文摘With the goal of designing a biologically inspired robot that can hold a stable hover under internal and external disturbances.We designed a tailless Flapping-wing Micro Aerial Vehicle(FMAV)with onboard 3D velocity perception.In this way,the wind disturbance caused by the relative motion of the FMAV can be quantified in real time based on the established altitudinal dynamics model.For the rest of the total disturbance,an active disturbance rejection controller is proposed to estimate and suppress those disturbances.In comparison with the traditional PID controller,this proposed approach has been validated.The results show that,in the hovering flight with the internal unmodeled dynamics,the root-mean-square of height controlled is only 2.53 cm.Even with the different weights of loads mounting on the FMAV,the ascending trajectory of flights remains impressively consistent.In the forward flight with the external disturbance,the root-mean-square error of height controlled is 2.78 cm.When the FMAV flies over a ladder introducing an abrupt external disturbance,the maximum overshoot is only half of that controlled by the PID controller.To our best knowledge,this is the first demonstration of FMAVs with the capability of sensing motion-generated wind disturbance onboard and handling the internal and external disturbances in hover flight. | Jiawang Mou Weiping Zhang Kexin Zheng Yao Wang Chaofeng Wu | 2022 | Journal of Bionic Engineering2022，19，6： | 2 |
| 18 | Will the Historic Southeasterly Wind over the Equatorial Pacific in March 2022 Trigger a Third-year La Niña Event?显示文摘Based on the updates of the Climate Prediction Center and International Research Institute for Climate and Society(CPC/IRI)and the China Multi-Model Ensemble(CMME)El Niño-Southern Oscillation(ENSO)Outlook issued in April 2022,La Niña is favored to continue through the boreal summer and fall,indicating a high possibility of a three-year La Niña(2020-23).It would be the first three-year La Niña since the 1998-2001 event,which is the only observed three-year La Niña event since 1980.By examining the status of air-sea fields over the tropical Pacific in March 2022,it can be seen that while the thermocline depths were near average,the southeasterly wind stress was at its strongest since 1980.Here,based on a quaternary linear regression model that includes various relevant air-sea variables over the equatorial Pacific in March,we argue that the historic southeasterly winds over the equatorial Pacific are favorable for the emergence of the third-year La Niña,and both the anomalous easterly and southerly wind stress components are important and contribute~50%of the third-year La Niña growth,respectively.Additionally,the possible global climate impacts of this event are discussed. | Xianghui FANG Fei ZHENG Kexin LI Zeng-Zhen HU Hongli REN Jie WU Xingrong CHEN Weiren LAN Yuan YUAN Licheng FENG Qifa CAI Jiang ZHU | 2023 | Advances in Atmospheric Sciences2023，40，1： | 2 |
| 19 | National Cancer Data Linkage Platform of China:Design,Methods,and Application显示文摘Background:The National Cancer Center(NCC)and China CDC cooperatively designed a National Cancer Data Linkage(NCDL)Platform to fulfill the task of sharing cancer outcome data through an automatic web-based system.Methods:NCC and China CDC established a web-based NCDL Platform to link death information from China CDC with the cancer database from NCC.Overall,76,708 cancer patients’data were analyzed to assess the feasibility and match rate of the NCDL Platform for 7 major cancers.Results:The function of the platform includes a data application and approval system,data linkage module,and results visualization system.Through the platform,38.9%cases were identified as deaths cases from the NCDL Platform in the first 3 years after cancer diagnosis.The linkage rate was highest in liver cancer and lowest in breast cancer.Conclusions:The NCDL Platform provides a powerful and efficient way to link national vital statistics with national cancer programs’data.Expanding cancer outcome data linkage may not only improve data collection efficiency,but also improve data use. | Hongmei Zeng Yunning Liu Lijun Wang Peng Yin Baohua Wang Ruiying Fu Xianhui Ran Rongshou Zheng Siwei Zhang Jiangmei Liu Jinling You Kexin Sun Shaoming Wang Li Li Ru Chen Wenqiang Wei Maigeng Zhou Jing Wu Jie He | 2022 | China CDC weekly2022，4，13： | 1 |
| 20 | Trends in Incidence Rates,Mortality Rates,and Age-Period-Cohort Effects of Female Breast Cancer—China,2003-2017显示文摘Introduction:This study reported the trends in female breast cancer incidence and mortality rates in China,and analyzed the corresponding age-periodcohort effects.Methods:Data from 22 population-based cancer registries in China between 2003 and 2017 were analyzed.Age-standardized incidence rates(ASIR)and mortality rates(ASMR)were calculated using Segi’s world standard population.Joinpoint regression was employed to evaluate trends,and age-period-cohort effects were examined using the intrinsic estimator method.Results:The ASIR for female breast cancer exhibited a more rapid increase in rural areas compared to urban areas across all age groups.The most substantial increase was observed in the 20-34 age group in rural areas[annual percent change(APC)=9.0%,95%confidence interval(CI):7.0%-11.0%,P<0.001].The ASMR for females under 50 years old remained stable from 2003 to 2017 in both urban and rural areas.However,the ASMR for females over 50 in rural areas and those over 65 in urban areas demonstrated a significant increase,with the most pronounced increase observed among females over 65 in rural areas(APC=4.9%,95%CI:2.8%-7.0%,P<0.001).Age-period-cohort analysis revealed increasing period effects and decreasing cohort effects for female breast cancer incidence and mortality rates in both urban and rural settings.Notably,the cohort effect for incidence displayed a slight upward trend for females born between 1983 and 1992 in rural areas.Conclusions:Our study revealed a rapid increase in breast cancer incidence among younger generations and an accelerated mortality rate in older populations residing in rural areas.To effectively address the growing burden of female breast cancer in China,it is essential to develop and implement targeted intervention strategies. | Kexin Sun Lin Lei Rongshou Zheng Siwei Zhang Hongmei Zeng Shaoming Wang Li Li Ru Chen Bingfeng Han Ji Peng Wenqiang Wei Jie He | 2023 | China CDC weekly2023，5，15： | 1 |
