2Liver 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
3Cancer 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 2018Chinese Journal of Cancer Research2018,30,1:832
4Incidence and mortality of stomach cancer in China,2014显示文摘Objective: In this study,we aimed to estimate the updated incidence and mortality rate of stomach cancer based on the cancer registration data in 2014,collected by the National Central Cancer Registry of China(NCCRC).Methods: In 2017,339 registries' data were qualified based on the criteria of data quality control of the NCCRC.Cases of stomach cancer were retrieved from the national database.We estimated numbers of stomach cancer cases and deaths in China using age-specific rates and corresponding national population stratified by area,sex,agegroup(0,1–4,5–9,10–14,…,85+).Chinese standard population in 2000 and Segi's world population were applied for age-standardized incidence and mortality rates.Results: In 2014,410,400 new stomach cancer cases and 293,800 cancer-associated deaths were estimated to have occurred in China.The crude incidence rate of stomach cancer was 30.00/100,000,age-standardized incidence rates by Chinese standard population(ASIRC) and by world standard population(ASIRW) were 19.62/100,000 and19.51/100,000,respectively.The crude mortality rate of stomach cancer was 21.48/100,000,age-standardized mortality rates by Chinese(ASMRC) and by world standard population(ASMRW) were 13.44/100,000 and13.30/100,000,respectively.Incidence and mortality rates in rural areas were both higher than that in urban areas.Stomach cancer has a strong relationship with gender and age.The disease has occurred more frequently among men than women with a male to female ratio of 2.4 for ASIRC.After age group of 40-44 years,incidence rates are substantially higher in men than in women,same pattern was seen for age-specific mortality rates.Conclusions: There is still a heavy burden of stomach cancer in China.The incidence and mortality patterns of stomach cancer show substantial gender and regional disparities.Great effort is needed to provide more accessible health services,sufficient financial resources,and adequate cancer-care infrastructure for the Chinese population,especially for people living in rural areas.Lei Yang Rongshou Zheng Ning Wang Yannan Yuan Shuo Liu Huichao Li Siwei Zhang Hongmei Zeng Wanqing Chen 2018Chinese Journal of Cancer Research2018,30,3:114

8Early Oligocene anatexis in the Yardoi gneiss dome,southern Tibet and geological implications显示文摘The Yardoi gneiss dome is located to the easternmost of the North Himalayan Gneiss Dome (NHGD),southern Tibet. It consists of metapelite,garnet amphibolite,granite and leucogranite,and is a key subject to constrain the formation and tectonic evolution of NHGD. SHRIMP zircon U/Pb data on the leucogranite yield an age of 35.3±1.1 Ma,which is substantially older than that of the similar leu-cogranites to the west. Sr and Nd isotope systematics indicate that this leucogranite was derived from partial melting of the mixed garnet amphibolite and metapelite. Our data suggest that (1) during the early stage of Himalayan magmatism,amphibolite dehydration melting overwhelmed that of the metapelite; and (2) such a melting at middle-lower crust might be a major factor that initiated the movement along the Southern Tibetan Detachment System (STDS).ZENG LingSen LIU Jing GAO LiE XIE KeJia WEN Li 2009Chinese Science Bulletin2009,54,1:61

11High expression of ACE2 receptor of 2019-nCoV on the epithelial cells of oral mucosa显示文摘It has been reported that ACE2 is the main host cell receptor of 2019-nCoV and plays a crucial role in the entry of virus into the cell to cause the final infection. To investigate the potential route of 2019-n Cov infection on the mucosa of oral cavity, bulk RNA-seq profiles from two public databases including The Cancer Genome Atlas(TCGA) and Functional Annotation of The Mammalian Genome Cap Analysis of Gene Expression(FANTOM5 CAGE) dataset were collected. RNA-seq profiling data of 13 organ types with para-carcinoma normal tissues from TCGA and 14 organ types with normal tissues from FANTOM5 CAGE were analyzed in order to explore and validate the expression of ACE2 on the mucosa of oral cavity. Further, single-cell transcriptomes from an independent data generated in-house were used to identify and confirm the ACE2-expressing cell composition and proportion in oral cavity. The results demonstrated that the ACE2 expressed on the mucosa of oral cavity. Interestingly, this receptor was highly enriched in epithelial cells of tongue. Preliminarily, those findings have explained the basic mechanism that the oral cavity is a potentially high risk for 2019-nCoV infectious susceptibility and provided a piece of evidence for the future prevention strategy in dental clinical practice as well as daily life.Hao Xu Liang Zhong Jiaxin Deng Jiakuan Peng Hongxia Dan Xin Zeng Taiwen Li Qianming Chen 2020International Journal of Oral Science2020,12,1:69
12Black carbon aerosols and their radiative properties in the Pearl River Delta region显示文摘The climatic and environmental effects of atmospheric aerosols are a hot topic in global science community, and radiative properties of the aerosols are one of the important parameters in assessing climatic change. Here we studied the black carbon concentration and absorption coefficient measured with aethalometers, scattering coefficient measured with nephelometers, and single scattering albedo derived at an atmospheric composition watch station in Guangzhou from 2004 to 2007. Our main results are as follows. The data of black carbon concentration and absorption coefficients measured with instruments cannot be directly used until they are measured in parallel with internationally accepted instruments for comparison, calibration, and reduction. After evaluation of the data, the result shows that the monthly mean of BC concentration varies 3.1―14.8 μg·m-3 and the concentration decreases by about 1 μg·m-3 in average over the four years; It is higher in the dry season with a multi-year mean of 8.9 μg/m3 and lower in the rainy season with a multi-year mean of 8.0 μg·m-3; The extreme maximum of monthly mean concentration occurred in December 2004 and extreme minimum in July 2007, and a 4-year mean is 8.4 μg·m-3. It is also shown that monthly mean scattering coefficient derived varies 129 -565 Mm-1, monthly mean absorption coefficient 32-139 Mm-1, and monthly mean single scattering albedo 0.71-0.91, with annual mean values of 0.80, 0.82, 0.79 and 0.84 for 2004, 2005, 2006 and 2007, respectively. Three instruments were used to take simultaneous measurements of BC in PM10, PM2.5, and PM1 and the results showed that PM2.5 took up about 90% of PM10 and PM1 accounted for about 68% of PM2.5, and BC aerosols are mainly present in fine particulates. The variability of BC concentrations is quite consistent between the Nancun station (141 m above sea level) and the Panyu station (13 m above sea level), which are 8 km apart from each other. The concentration in higher altitude station (Panyu) is consistently lower than the lower altitude station (Nancun), and the difference of annual mean is about 4 μg·m-3.WU Dui MAO JieTai DENG XueJiao TIE XueXi ZHANG YuanHang ZENG LiMin LI Fei TAN HaoBo BI XueYan HUANG XiaoYing CHEN Jing DENG Tao 2009Science China Earth Sciences2009,52,8:58

17Heavy Metal Content in Chinese Vegetable Plantation Land Soils and Related Source Analysis显示文摘According to the previous literature published since 1989,statistical analysis for reported data on the heavy metals in Chinese vegetable plantation soils was carried out systematically in this article. The purpose of this investigation was to study the status of heavy metal content in vegetable land soils systematically through objective assessment to promote the development of vegetable production with high quality and efficiency. It is concluded that Zn,Cr,Cu had relatively high concentrations while the mean concentrations of toxic metals,As,Hg,Cd were 8.03,0.12,0.28 mg kg-1,respectively with comparatively low concentrations in Chinese vegetable land. Comparing to Chinese Soil Quality Criterion GB 15618-1995 (6.5 < pH < 7.5),about 24.1,10.3,and 9.2% of the total samples was contaminated by Cd,Hg,and As,respectively,and the descending order of heavy metals was Cd > Hg > As > Zn > Cu > Cr > Pb. When compared among different regions,the more serious heavy metal contamination was found in the vegetable land of eastern China and the main contamination elements were Cd,Hg,and Zn. In the mid region,vegetable plantation land soil was mainly polluted by As and Cd,as well as by Hg,Zn,and Cu,to some extent. In the west region of China,Cd and As contamination was also observed to some degree,along with few soil samples exceeding the grade II level of GB 15618-1995 (6.5 < pH < 7.5) for Cu,Cr,and Hg content. Compared to the five vegetable plantation land patterns,the highest concentration of As,Cd,Hg,and Zn occurred in the industrial/sewage irrigation vegetable land,especially for Hg with 2.36 mg kg-1 content averagely,which is 10.5-21.1 times higher than the other four types of vegetable lands. The highest concentration of Cu and Cr occurred in the greenhouse vegetable land soils,and urban vegetable land soil had the highest Pb content in comparison with the other types of vegetable plantation land patterns. By analyzing heavy metal content under different vegetable land patterns,it was found that soil in vegetable production base had relatively low heavy metal concentrations except for Pb with a slightly higher amount in the suburb area. The soil quality of common vegetable land was good with the lowest concentrations for most heavy metals. Under present utilization patterns of vegetable land,the soil quality in Chinese vegetable base land was good with comparatively low concentrations of heavy metals and mostly not exceeding the grade II level of Chinese Soil Quality Criterion GB 15618-1995 (6.5 < pH < 7.5). However,comparatively serious contamination was found in industrial/sewage irrigation and suburb vegetable land soils.ZENG Xi-bai LI Lian-fang MEI Xu-rong 2008Agricultural Sciences in China2008,7,9:46
