1Cancer Incidence and Mortality in China,2007显示文摘Objective:Cancer incidence and mortality data collected from population-based cancer registries were analyzed to present the overall cancer statistics in Chinese registration areas by age,sex and geographic area in 2007.Methods:In 2010,48 cancer registries reported cancer incidence and mortality data of 2007 to National Central Cancer Registry of China.Of them,38 registries' data met the national criteria.Incidence and mortality were calculated by cancer sites,age,gender,and area.Age-standardized rates were described by China and World population.Results:The crude incidence rate for all cancers was 276.16/100,000(305.22/100,000 for male and 246.46/100,000 for female;284.71/100,000 in urban and 251.07/100,000 in rural).Age-standardized incidence rates by China and World population were 145.39/100,000 and 189.46/100,000 respectively.The crude mortality rate for all cancers was 177.09/100,000(219.15/100,000 for male and 134.10/100,000 for female;173.55/100,000 in urban and 187.49/100,000 in rural).Age-standardized mortality rates by China and World population were 86.06/100,000 and 116.46/100,000,respectively.The top 10 most frequently common cancer sites were the lung,stomach,colon and rectum,liver,breast,esophagus,pancreas,bladder,brain and lymphoma,accounting for 76.12% of the total cancer cases.The top 10 causes of cancer death were cancers of the lung,liver,stomach,esophagus,colon and rectum,pancreas,breast,leukemia,brain and lymphoma,accounting for 84.37% of the total cancer deaths.Conclusion: Cancer remains a major disease threatening people's health in China. Prevention and control should be enhanced, especially for the main cancers.Wan-qing Chen Hong-mei Zeng Rong-shou Zheng Si-wei Zhang Jie He 2012Chinese Journal of Cancer Research2012,24,1:88
2The incidences and mortalities of major cancers in China, 2009显示文摘In 2012, the National Central Cancer Registry (NCCR) of China collected cancer registration information for the year 2009 from local cancer registries and analyzed it to describe the incidences and mortalities of cancers in China. Based on the data quality criteria from NCCR, data from 104 registries covering 85,470,522 people (57,489,009 in urban areas and 27,981,513 in rural areas) were checked and evaluated. The data from 72 registries were qualified and accepted for the cancer registry annual report in 2012. The total cancer incident cases and cancer deaths were 244,366 and 154,310, respectively. The morphologically verified cases accounted for 67.23%, and 3.14% of the incident cases only had information from death certifications. The crude incidence in the Chinese cancer registration areas was 285.91/ 100,000 (317.97/100,000 in males and 253.09/100,000 in females). The age-standardized rates for incidences based on the Chinese standard population (ASRIC) and the world standard population (ASRIW) were 146.87/100,000 and 191.72/100,000, respectively, with a cumulative incidence of 22.08%. The cancer mortality in the Chinese cancer registration areas was 180.54/100,000 (224.20/100,000 in males and 135.85/100,000 in females). The age-standardized rates for mortalities based on the Chinese standard population (ASRMC) and the world standard population (ASRMW) were 85.06/100,000 and 115.65/100,000, respectively, and the cumulative mortality was 12.94% . Lung cancer, gastric cancer, colorectal cancer, liver cancer, esophageal cancer, pancreatic cancer, encephaloma, lymphoma, female breast cancer, and cervical cancer were the most common cancers, accounting for 75% of all cancer cases. Lung cancer, gastric cancer, liver cancer, esophageal cancer, colorectal cancer, pancreatic cancer, breast cancer, encephaloma, leukemia, and lymphoma accounted for 80% of all cancer deaths. The cancer registration's population coverage has been increasing, and its data quality is improving. As the basis of the cancer control program, the cancer registry plays an important role in directing anticancer strategies in the medium and long term. Because cancer burdens are different in urban and rural areas in China, prevention and control efforts should be based on practical situations.Wanqing Chen Rongshou Zheng Siwei Zhang Ping Zhao Guanglin Li Lingyou Wu Jie He 2013Chinese Journal of Cancer2013,32,3:111
3Report of incidence and mortality in China cancer registries, 2009显示文摘Objective: The National Central Cancer Registry (NCCR) collected cancer registration data in 2009 from local cancer registries in 2012, and analyzed to describe cancer incidence and mortality in China. Methods: On basis of the criteria of data quality from NCCR, data submitted from 104 registries were checked and evaluated. There were 72 registries' data qualified and accepted for cancer registry annual report in 2012. Descriptive analysis included incidence and mortality stratified by area (urban/rural), sex, age group and cancer site. The top 10 common cancers in different groups, proportion and cumulative rates were also calculated. Chinese population census in 1982 and Segi's population were used for age-standardized incidence/mortality rates. Results: All 72 cancer registries covered a total of 85,470,522 population (57,489,009 in urban and 27,981,513 in rural areas). The total new cancer incident cases and cancer deaths were 244,366 and 154,310, respectively. The morphology verified cases accounted for 67.23%, and 3.14% of incident cases only had information from death certifications. The crude incidence rate in Chinese cancer registration areas was 285.91/100,000 (males 317.97/100,000, females 253.09/100,000), age-standardized incidence rates by Chinese standard population (ASIRC) and by world standard population (ASIRW) were 146.87/100,000 and 191.72/100,000 with the cumulative incidence rate (0-74 age years old) of 22.08%. The cancer incidence and ASIRC were 303.39/100,000 and 150.31/100,000 in urban areas whereas in rural areas, they were 249.98/100,000 and 139.68/100,000, respectively. The cancer mortality in Chinese cancer registration areas was 180.54/100,000 (224.20/100,000 in males and 135.85/100,000 in females), age-standardized mortality rates by Chinese standard population (ASMRC) and by world standard population (ASMRW) were 85.06/100,000 and 115.65/100,000, and the cumulative incidence rate (0-74 age years old) was 12.94%. The cancer mortality and ASMRC were 181.86/100,000 and 80.86/100,000 in urban areas, whereas in rural areas, they were 177.83/100,000 and 94.40/100,000 respectively. Lung cancer, gastric cancer, colorectal cancer, liver cancer, esophageal cancer, pancreas cancer, encephaloma, lymphoma, female breast cancer and cervical cancer, were the most common cancers, accounting for 75% of all cancer cases in urban and rural areas. Lung cancer, gastric cancer, liver cancer, esophageal cancer, colorectal cancer, pancreatic cancer, breast cancer, encephaloma, leukemia and lymphoma accounted for 80% of all cancer deaths. The cancer spectrum showed difference between urban and rural areas, males and females. The main cancers in rural areas were cancers of the stomach, followed by esophageal cancer, lung cancer, liver cancer and colorectal cancer, whereas the main cancer in urban areas was lung cancer, followed by liver cancer, gastric cancer and colorectal cancer. Conclusions: The coverage of cancer registration population has been increasing and data quality is improving. As the basis of cancer control program, cancer registry plays an important role in making anticancer strategy in medium and long term. As cancer burdens are different between urban and rural areas in China, prevention and control should be implemented based on practical situation.Wanqing Chen Rongshou Zheng Siwei Zhang Ping Zhao Guanglin Li Lingyou Wu Jie He 2013Chinese Journal of Cancer Research2013,25,1:202
4Annual report on status of cancer in China,2010显示文摘Objective:Population-based cancer registration data in 2010 were collected,evaluated and analyzed by the National Central Cancer Registry(NCCR) of China.Cancer incident new cases and cancer deaths were estimated.Methods:There were 219 cancer registries submitted cancer incidence and death data in 2010.All data were checked and evaluated on basis of the criteria of data quality from NCCR.Total 145 registries' data were qualified and accepted for cancer statistics in 2010.Pooled data were stratified by urban/rural,area,sex,age group and cancer site.Cancer incident cases and deaths were estimated using age-specific rates and national population.The top ten common cancers in different groups,proportion and cumulative rate were also calculated.Chinese census in 2000 and Segi's population were used for age-standardized incidence/ mortality rates.Results:All 145 cancer registries(63 in urban and 82 in rural) covered a total of 158,403,248 population(92,433,739 in urban and 65,969,509 in rural areas).The estimates of new cancer incident cases and cancer deaths were 3,093,039 and 1,956,622 in 2010,respectively.The morphology verified cases(MV%) accounted for 67.11% and 2.99% of incident cases were identified through death certifications only(DCO%) with mortality to incidence ratio(M/I) of 0.61.The crude incidence rate was 235.23/100,000(268.65/100,000 in males,200.21/100,000 in females),age-standardized incidence rates by Chinese standard population(ASIRC,2000) and by world standard population(ASIRW) were 184.58/100,000 and 181.49/100,000 with the cumulative incidence rate(0-74 years old) of 21.11%.The cancer incidence and ASIRC were 256.41/100,000 and 187.53/100,000 in urban areas whereas in rural areas,they were 213.71/100,000 and 181.10/100,000,respectively.The crude cancer mortality in China was 148.81/100,000(186.37/100,000 in males and 109.42/100,000 in females),age-standardized incidence rates by Chinese standard population(ASMRC,2000) and by world standard population(ASMRW) were 113.92/100,000 and 112.86/100,000,and the cumulative incidence rate(0-74 years old) was 12.78%.The cancer mortality and ASMRC were 156.14/100,000 and 109.21/100,000 in urban areas,whereas in rural areas,they were 141.35/100,000 and 119.00/100,000 respectively.Lung cancer,gastric cancer,colorectal cancer,liver cancer,esophageal cancer,pancreas cancer,encephaloma,lymphoma,female breast cancer and cervical cancer,were the most common cancers,accounting for 75% of all cancer cases in urban and rural areas.Lung cancer,gastric cancer,liver cancer,esophageal cancer,colorectal cancer,pancreatic cancer,breast cancer,encephaloma,leukemia and lymphoma accounted for 80% of all cancer deaths.Conclusions:The coverage of cancer registration population had a rapid increase and could reflect cancer burden in each area and population.As the basis of cancer control program,cancer registry plays an irreplaceable role in cancer epidemic surveillance,evaluation of cancer control programs and making anticancer strategy.China is facing serious cancer burden and prevention and control should be enhanced.Wanqing Chen Rongshou Zheng Siwei Zhang Ping Zhao Hongmei Zeng Xiaonong Zou Jie He 2014Chinese Journal of Cancer Research2014,26,1:198
5Liver cancer incidence and mortality in China: Temporal trends and projections to 2030显示文摘Objective: Liver cancer is one of the most common cancers and major cause of cancer deaths in China,which accounts for over 50% of new cases and deaths worldwide.The systematic liver cancer statistics including of projection through 2030 could provide valuable information for prevention and control strategies in China,and experience for other countries.Methods: The burden of liver cancer in China in 2014 was estimated using 339 cancer registries' data selected from Chinese National Cancer Center(NCC).Incident cases of 22 cancer registries were applied for temporal trends from 2000 to 2014.The burden of liver cancer through 2030 was projected using age-period-cohort model.Results: About 364,800 new cases of liver cancer(268,900 males and 95,900 females) occurred in China,and about 318,800 liver cancer deaths(233,500 males and 85,300 females) in 2014.Western regions of China had the highest incidence and mortality rates.Incidence and mortality rates decreased by about 2.3% and 2.6% per year during the period of 2000-2014,respectively,and would decrease by more than 44% between 2014 and 2030 in China.The young generation,particularly for those aged under 40 years,showed a faster down trend.Conclusions: Based on the analysis,incidence and mortality rates of liver cancer are expected to decrease through 2030,but the burden of liver cancer is still serious in China,especially in rural and western areas.Most cases of liver cancer in China can be prevented through vaccination and more prevention efforts should be focused on high risk groups.Rongshou Zheng Chunfeng Qu Siwei Zhang Hongmei Zeng Kexin Sun Xiuying Gu Changfa Xia Zhixun Yang He Li Wenqiang Wei Wanqing Chen Jie He 2018Chinese Journal of Cancer Research2018,30,6:132
6Annual report on status of cancer in China, 2011显示文摘Objective: The National Central Cancer Registry(NCCR) collected population-based cancer registration data in 2011 from all cancer registries. National cancer incidence and mortality were compiled and cancer incident new cases and cancer deaths were estimated.Methods: In 2014, there were 234 cancer registries submitted cancer incidence and deaths occurred in 2011. All datasets were checked and evaluated based on the criteria of data quality from NCCR. Total 177 registries' data were qualified and compiled for cancer statistics in 2011. The pooled data were stratified by area(urban/rural), gender, age group(0, 1-4, 5-9, 10-14…85+) and cancer type. Cancer incident cases and deaths were estimated using age-specific rates and national population in 2011. All incidence and death rates are age-standardized to the 2000 Chinese standard population and Segi's population expressed per 100,000 persons.Results: All 177 cancer registries(77 in urban and 100 in rural areas) covered 175,310,169 populations(98,341,507 in urban and 76,968,662 in rural areas). The morphology verified cases(MV%) accounting for 70.14% and 2.44% of incident cases were identified through death certifications only(DCO%) with mortality to incidence ratio of 0.63. The estimates of new cancer incident cases and cancer deaths were 3,372,175 and 2,113,048 in 2011, respectively. The incidence rate was 250.28/100,000(males 277.77/100,000, females 221.37/100,000), and the age-standardized incidence rates by Chinese standard population(ASIRC) and by world standard population(ASIRW) were 186.34/100,000 and 182.76/100,000 with the cumulative incidence rate(0-74 years old) of 21.20%. The cancer incidence and ASIRC in urban areas were 261.38/100,000 and 189.89/100,000 compared to 238.60/100,000 and 182.10/100,000 in rural areas, respectively. The cancer mortality was 156.83/100,000(194.88/100,000 in males and 116.81/100,000 in females), the age-standardized mortality rates by Chinese standard population(ASMRC) and by world standard population(ASMRW) were 112.88/100,000 and 111.82/100,000, and the cumulative mortality rate(0-74 years old) was 12.69%. The cancer mortality and ASMRC were 154.37/100,000 and 108.20/100,000 in urban areas, and 159.42/100,000 and 117.97/100,000 in rural areas, respectively. Cancers of lung, female breast, stomach, liver, colon and rectum, esophageal, cervix, uterus, prostate and ovary were the most common cancers, accounting for about 75% of all cancer new cases. Lung cancer, liver cancer, stomach cancer, esophageal cancer, colorectal cancer, female breast cancer, pancreatic cancer, brain tumor, cervical cancer and leukemia were the leading causes of cancer death, accounting for about 80% of all cancer deaths. The cancer incidence, mortality and spectrum showed difference between urban and rural areas, males and females.Conclusions: The coverage of cancer registration population had a greater increase than that in the last year. The data quality and representativeness are gradually improved. As the basic work of cancer prevention and control, cancer registry is playing an irreplaceable role. The disease burden of cancer is increasing, and the health department has to take effective measures to contain the increased cancer burden in China.Wanqing Chen Rongshou Zheng Hongmei Zeng Siwei Zhang Jie He 2015Chinese Journal of Cancer Research2015,27,1:431
7National cancer incidence and mortality in China, 2012显示文摘Background: Population-based cancer registration data in 2012 from all available cancer registries were collected by the National Central Cancer Registry(NCCR). NCCR estimated the numbers of new cancer cases and cancer deaths in China with compiled cancer incidence and mortality rates.Methods: In 2015, there were 261 cancer registries submitted cancer incidence and deaths occurred in 2012. All the data were checked and evaluated based on the NCCR criteria of data quality. Qualified data from 193 registries were used for cancer statistics analysis as national estimation. The pooled data were stratified by area(urban/rural), gender, age group [0, 1–4, 5–9, 10–14, …, 85+] and cancer type. New cancer cases and deaths were estimated using age-specific rates and corresponding national population in 2012. The Chinese census data in 2000 and Segi's population were applied for age-standardized rates. All the rates were expressed per 100,000 person-year.Results: Qualified 193 cancer registries(74 urban and 119 rural registries) covered 198,060,406 populations(100,450,109 in urban and 97,610,297 in rural areas). The percentage of cases morphologically verified(MV%) and death certificate-only cases(DCO%) were 69.13% and 2.38%, respectively, and the mortality to incidence rate ratio(M/I) was 0.62. A total of 3,586,200 new cancer cases and 2,186,600 cancer deaths were estimated in China in 2012. The incidence rate was 264.85/100,000(289.30/100,000 in males, 239.15/100,000 in females), the age-standardized incidence rates by Chinese standard population(ASIRC) and by world standard population(ASIRW) were 191.89/100,000 and 187.83/100,000 with the cumulative incidence rate(0–74 age years old) of 21.82%. The cancer incidence, ASIRC and ASIRW in urban areas were 277.17/100,000, 195.56/100,000 and 190.88/100,000 compared to 251.20/100,000, 187.10/100,000 and 183.91/100,000 in rural areas, respectively. The cancer mortality was 161.49/100,000(198.99/100,000 in males, 122.06/100,000 in females), the age-standardized mortality rates by Chinese standard population(ASMRC) and by world standard population(ASMRW) were 112.34/100,000 and 111.25/100,000, and the cumulative mortality rate(0–74 years old) was 12.61%. The cancer mortality, ASMRC and ASMRW were 159.00/100,000, 107.231/100,000 and 106.13/100,000 in urban areas, 164.24/100,000, 118.22/100,000 and 117.06/100,000 in rural areas, respectively. Cancers of lung, stomach, liver, colorectum, esophagus, female breast, thyroid cervix, brain tumor and pancreas were the most common cancers, accounting for about 77.4% of all cancer new cases. Lung cancer, liver cancer, stomach cancer, esophageal cancer, colorectal cancer, pancreatic cancer, female breast cancer, brain tumor, leukemia and lymphoma were the leading causes of cancer death, accounting for about 84.5% of all cancer deaths. The cancer spectrum showed difference between urban and rural, males and females both in incidence and mortality rates.Conclusions: Cancer surveillance information in China is making great progress with the increasing number of cancer registries, population coverage and the improving data quality. Cancer registration plays a fundamental role in cancer control by providing basic information on population-based cancer incidence, mortality, survival and time trend. The disease burden of cancer is serious in China, so that, cancer prevention and control, including health education, health promotion, cancer screening and cancer care services in China, should be enhanced.Wanqing Chen Rongshou Zheng Tingting Zuo Hongmei Zeng Siwei Zhang Jie He 2016Chinese Journal of Cancer Research2016,28,1:238
8Cancer incidence and mortality in China in 2013:an analysis based on urbanization level显示文摘Objective: To explore the cancer patterns in areas with different urbanization rates(URR) in China with data from 255 population-based cancer registries in 2013, collected by the National Central Cancer Registry(NCCR).Methods: There were 347 cancer registries submitted cancer incidence and deaths occurred in 2013 to NCCR.All those data were checked and evaluated based on the NCCR criteria of data quality, and qualified data from 255 registries were used for this analysis. According to the proportion of non-agricultural population, we divided cities/counties into 3 levels: high level, with URR equal to 70% and higher; median level, with URR between 30%and 70%; and low level, with URR equal to 30% and less. Cancer incidences and mortalities were calculated,stratified by gender and age groups in different areas. The national population of Fifth Census in 2000 and Segi's population were applied for age-standardized rates.Results: Qualified 255 cancer registries covered 226,494,490 populations. The percentage of cases morphologically verified(MV%) and death certificate-only cases(DCO%) were 68.04% and 1.74%, respectively,and the mortality to incidence rate ratio(M/I) was 0.62. A total of 644,487 new cancer cases and 399,275 cancer deaths from the 255 cancer registries were submitted to NCCR in 2013. The incidence rate was 284.55/100,000(314.06/100,000 in males, 254.19/100,000 in females), and the age-standardized incidence rates by Chinese standard population(ASIRC) and by world standard population(ASIRW) were 190.10/100,000 and 186.24/100,000 with the cumulative incidence rate(0–74 age years old) of 21.60%. The cancer mortality was 176.28/100,000(219.03/100,000 in males, 132.30/100,000 in females), and the age-standardized mortality rates by Chinese standard population(ASMRC) and by world standard population(ASMRW) were 110.91/100,000 and 109.92/100,000, and the cumulative mortality rate(0–74 age years old) was 12.43%. Low urbanization areas were high in crude cancer incidence and mortality rates, middle urbanization areas came next to it followed by high urbanization areas. After adjusted by age, there was a U-shaped association between age-standardized incidence(ASIRC and ASIRW) and the urbanized ratio with the middle urbanization areas having the lowest ASIRC and ASIRW. Unlike with the agestandardized incidence, the sort order of age-standardized mortality(ASMRC and ASMRW) among three urbanization areas was reversed completely from the crude mortality. Lung cancer was the most common cancer in all areas of 255 cancer registries, followed by stomach cancer, liver cancer, colorectal cancer and esophageal cancer with new cases of 130,700, 76,200, 63,800, 60,900 and 50,200 respectively. Lung cancer was also the leading cause of cancer death in all areas of 255 cancer registries for both males and females with the number of deaths of 72,200 and 34,100, respectively. Other cancer types with high mortality in males were liver cancer, stomach cancer,esophageal cancer and colorectal cancer. In females, stomach cancer was the second cause of cancer death, followed by liver cancer, colorectal cancer and breast cancer.Conclusions: Along with the development of socioeconomics associated with urbanization, as well as the agingpopulation, the incidence and mortality keep increasing in China. Cancer burden and patterns are different in each urbanization level. Cancer control strategies should be implemented referring to local urbanization status.Wanqing Chen Rongshou Zheng Siwei Zhang Hongmei Zeng Tingting Zuo Changfa Xia Zhixun Yang Jie He 2017Chinese Journal of Cancer Research2017,29,1:305
9Cancer 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.

10Towards 6G wireless communication networks:vision,enabling technologies,and new paradigm shifts显示文摘The fifth generation(5G)wireless communication networks are being deployed worldwide from 2020 and more capabilities are in the process of being standardized,such as mass connectivity,ultra-reliability,and guaranteed low latency.However,5G will not meet all requirements of the future in 2030 and beyond,and sixth generation(6G)wireless communication networks are expected to provide global coverage,enhanced spectral/energy/cost efficiency,better intelligence level and security,etc.To meet these requirements,6G networks will rely on new enabling technologies,i.e.,air interface and transmission technologies and novel network architecture,such as waveform design,multiple access,channel coding schemes,multi-antenna technologies,network slicing,cell-free architecture,and cloud/fog/edge computing.Our vision on 6G is that it will have four new paradigm shifts.First,to satisfy the requirement of global coverage,6G will not be limited to terrestrial communication networks,which will need to be complemented with non-terrestrial networks such as satellite and unmanned aerial vehicle(UAV)communication networks,thus achieving a space-airground-sea integrated communication network.Second,all spectra will be fully explored to further increase data rates and connection density,including the sub-6GHz,millimeter wave(mmWave),terahertz(THz),and optical frequency bands.Third,facing the big datasets generated by the use of extremely heterogeneous networks,diverse communication scenarios,large numbers of antennas,wide bandwidths,and new service requirements,6G networks will enable a new range of smart applications with the aid of artificial intelligence(AI)and big data technologies.Fourth,network security will have to be strengthened when developing 6G networks.This article provides a comprehensive survey of recent advances and future trends in these four aspects.Clearly,6G with additional technical requirements beyond those of 5G will enable faster and further communications to the extent that the boundary between physical and cyber worlds disappears.Xiaohu YOU Cheng-Xiang WANG Jie HUANG Xiqi GAO Zaichen ZHANG Mao WANG Yongming HUANG Chuan ZHANG Yanxiang JIANG Jiaheng WANG Min ZHU Bin SHENG Dongming WANG Zhiwen PAN Pengcheng ZHU Yang YANG Zening LIU Ping ZHANG Xiaofeng TAO Shaoqian LI Zhi CHEN Xinying MA Chih-Lin I Shuangfeng HAN Ke LI Chengkang PAN Zhimin ZHENG Lajos HANZO Xuemin(Sherman)SHEN Yingjie Jay GUO Zhiguo DING Harald HAAS Wen TONG Peiying ZHU Ganghua YANG Jun WANG Erik GLARSSON Hien Quoc NGO Wei HONG Haiming WANG Debin HOU Jixin CHEN Zhe CHEN Zhangcheng HAO Geoffrey Ye LI Rahim TAFAZOLLI Yue GAO HVincent POOR Gerhard P.FETTWEIS Ying-Chang LIANG 2021Science China(Information Sciences)2021,64,1:122
11Breast 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 2021Cancer Biology & Medicine2021,18,3:53

13Report of Incidence and Mortality in China Cancer Registries,2008显示文摘Objective: Annual cancer incidence and mortality in 2008 were provided by National Central Cancer Registry in China, which data were collected from population‐based cancer registries in 2011. Methods: There were 56 registries submitted their data in 2008. After checking and evaluating the data quality, total 41 registries' data were accepted and pooled for analysis. Incidence and mortality rates by area (urban or rural areas) were assessed, as well as the age‐ and sex‐specific rates, age‐standardized rates, proportions and cumulative rate. Results: The coverage population of the 41 registries was 66,138,784 with 52,158,495 in urban areas and 13,980,289 in rural areas. There were 197,833 new cancer cases and 122,136 deaths in cancer with mortality to incidence ratio of 0.62. The morphological verified rate was 69.33%, and 2.23% of cases were identified by death certificate only. The crude cancer incidence rate in all areas was 299.12/100,000 (330.16/100,000 in male and 267.56/100,000 in female) and the age‐standardized incidence rates by Chinese standard population (ASIRC) and world standard population (ASIRW) were 148.75/100,000 and 194.99/100,000, respectively. The cumulative incidence rate (0-74 years old) was of 22.27%. The crude incidence rate in urban areas was higher than that in rural areas. However, after adjusted by age, the incidence rate in urban was lower than that in rural. The crude cancer mortality was 184.67/100,000 (228.14/100,000 in male and 140.48/100,000 in female), and the age‐standardized mortality rates by Chinese standard population (ASMRC) and by world population were 84.36/100,000 and 114.32/100,000, respectively. The cumulative mortality rate (0-74 years old) was of 12.89%. Age‐adjusted mortality rates in urban areas were lower than that in rural areas. The most common cancer sites were lung, stomach, colon‐rectum, liver, esophagus, pancreas, brain, lymphoma, breast and cervix which accounted for 75% of all cancer incidence. Lung cancer was the leading cause of cancer death, followed by gastric cancer, liver cancer, esophageal cancer, colorectal cancer and pancreas cancer, which accounted for 80% of all cancer deaths. The cancer spectrum varied by areas and sex in rural areas, cancers from digestive system were more common, such as esophageal cancer, gastric cancer and liver cancer, while incidence rates of lung cancer and colorectal cancer were much higher in urban areas. In addition, breast cancer was the most common cancer in urban women followed by liver cancer, gastric cancer and colorectal cancer. Conclusion: Lung cancer, gastric cancer, colorectal cancer, liver cancer, esophageal cancer and female breast cancer contributed to the increased incidence of cancer, which should be paid more attention to in further national cancer prevention and control program. Different cancer control strategies should be carried out due to the varied cancer spectrum in different groups.Wan-qing C hen Rong-shou Zheng Si-wei Zhang Ni Li Ping Zhao Guang-lin Li Liang-you Wu Jie He 2012Chinese Journal of Cancer Research2012,24,3:45

15Where Does AlphaGo Go: From Church-Turing Thesis to AlphaGo Thesis and Beyond显示文摘An investigation on the impact and significance of the Alpha Go vs. Lee Sedol Go match is conducted, and concludes with a conjecture of the Alpha Go Thesis and its extension in accordance with the Church-Turing Thesis in the history of computing. It is postulated that the architecture and method utilized by the Alpha Go program provide an engineering solution for tackling issues in complexity and intelligence. Specifically,the Alpha Go Thesis implies that any effective procedure for hard decision problems such as NP-hard can be implemented with Alpha Go-like approach. Deep rule-based networks are proposed in attempt to establish an understandable structure for deep neural networks in deep learning. The success of Alpha Go and corresponding thesis ensure the technical soundness of the parallel intelligence approach for intelligent control and management of complex systems and knowledge automation.Fei-Yue Wang Jun Jason Zhang Xinhu Zheng Xiao Wang Yong Yuan Xiaoxiao Dai Jie Zhang Liuqing Yang 2016IEEE/CAA Journal of Automatica Sinica2016,3,2:44
16Solid state fermentation of rapeseed cake with Aspergillus niger for degrading glucosinolates and upgrading nutritional value显示文摘Background:Rapeseed cake is a good source of protein for animal feed but its utilization is limited due to the presence of anti-nutritional substances,such as glucosinolates(GIs),phytic acid,tannins etc.In the present study,a solid state fermentation(SSF) using Aspergillus niger was carried out with the purpose of degrading glucosinolates and improving the nutritional quality of rapeseed cake(RSC).The effects of medium composition and incubation conditions on the GIs content in fermented rapeseed cake(FRSC) were investigated,and chemical composition and amino acid in vitro digestibility of RSC substrate fermented under optimal conditions were determined.Results:After 72 h of incubation at 34℃,a 76.89%decrease in GIs of RSC was obtained in solid medium containing 70%RSC,30%wheat bran at optimal moisture content 60%(w/w).Compared to unfermented RSC,trichloroacetic acid soluble protein(TCA-SP),crude protein and ether extract contents of the FRSC were increased(P< 0.05) 103.71,23.02 and 23.54%,respectively.As expected,the contents of NDF and phytic acid declined(P< 0.05) by 9.12 and 44.60%,respectively.Total amino acids(TAA) and essential amino acids(EAA) contents as well as AA in vitro digestibility of FRSC were improved significantly(P< 0.05).Moreover,the enzyme activity of endoglucanase,xylanase,acid protease and phytase were increased(P<0.05) during SSF.Conclusions:Our results indicate that the solid state fermentation offers an effective approach to improving the quality of proteins sources such as rapeseed cake.Changyou Shi Jun He Jie Yu Bing Yu Zhiqing Huang Xiangbing Mao Ping Zheng Daiwen Chen 2015Journal of Animal Science and Biotechnology2015,6,3:32
