1Expenditure of hospital care on cancer in China, from 2011 to 2015显示文摘Objective: A solid understanding of levels and trends of spending on cancer is important to evaluate whether our healthcare resources were wisely spent and to prioritize future resources for cancer treatment and prevention.However, studies on economic burden of cancers in China are scant and the results are inconsistent.Methods: The Chinese hospital information database and nearly 350 million inpatient medical record data were used. As the ratios of cancer inpatient payments to total inpatient payments were mainly influenced by the grades and sites of hospitals, the estimates of payments of cancer inpatients in this study were stratified by hospital grades and provinces. Only the payments of cancer inpatients happened in grade 2, grade 3 and specialized cancer hospitals were included in the analyses. The total medical payments of cancers in China were estimated based on the ratios of outpatient payments to inpatient payments in specialized cancer hospitals.Results: From 2011 to 2015, the payments of cancer inpatients in China have increased by 84.1% and the total inpatient payments reached 177.1 billion RMB in 2015, accounting for 4.3% of the total health expenditure in China. Based on the ratio of outpatient payments to inpatient payments, the total payments on cancer treatments in China were estimated to be 221.4 billion RMB in 2015. Among different cancer types, the highest payments were the treatment of trachea, bronchus and lung cancer. The major cancer inpatient payments(67.1% in 2015) spent in grade 3 general hospitals and this ratio increased continually from 2011 to 2015. The expenditure of cancer treatments also varies by region with the major expenditure in the eastern region of China.Conclusions: This study estimated the total payments of cancer treatments in China and analyzed how the money was spent on cancer treatments in the recent 5 years, which would provide information for decision makings on the allocation of resources to service provisioning, prevention strategies, research funding, and assessing whether the economic burden of cancer is affordable to the governments.Yue Cai Ming Xue Wanqing Chen Maogui Hu Zhiwen Miao Lan Lan Rongshou Zheng Qun Meng 2017Chinese Journal of Cancer Research2017,29,3:81
2Applications of LA-ICP-MS in the elemental analyses of geological samples显示文摘Laser ablation-inductively coupled plasma-mass spectrometry(LA-ICP-MS),which is a rapidly developing analytical technique for the analyses of trace elements and isotopes,plays an important role in advancing the study of Earth science,especially with respect to micro-geochemistry.This article reviews the application of LA-ICP-MS in the elemental analysis of solid geological samples.Although LA-ICP-MS has been widely used in the spatial resolution analysis of element compositions and rapid bulk analysis of whole-rock and soil samples,the analysis accuracy is restricted by numerous factors,including the instrumental conditions,the elemental fractionation and matrix effects,the lack of sufficient matrix-matched reference materials,and the strategies for quantitative calibration and sensitivity drift correction.According to the type of samples and the analyte elements,the analysis accuracy can be improved through the optimization of instrument conditions and the adoption of suitable correction strategies and reference materials.LIU YongSheng HU ZhaoChu LI Ming GAO Shan 2013Chinese Science Bulletin2013,58,32:42

9Palaeogeothermal response and record of the effusing of Emeishan basalts in the Sichuan basin显示文摘Thermal history of the Sichuan basin is reconstructed based on vitrinite reflectance from boreholes in the basin using a paleo-heat flow method.The results show that the Sichuan basin experienced a relatively low heat flow period in the Early Paleozoic,and an elevated paleo-heat flow,ranging 60-80 mW/m2 with a maximum as high as 100 mW/m2 around 259 Ma,from the beginning of the Late Paleozoic to the end of the early Permian,and a decreased paleo-heat flow from the late Permian to the late Triassic,and then maintained nearly stable to the present.The Late Paleozoic paleo-heat flow was quite high where there were extensive Emeishan flood basalts or concealed basalts which erupted between the early and the late Permian,such as the southwestern and northeastern areas of the Sichuan basin.According to the distribution of paleo-heat flow,it can be inferred that,the northeastern Sichuan basin was also influenced by the Emeishan magmatic activity during the Dongwu movement though there was lack of Emeishan flood basalts.In addition,the results of thermal history reconstruction of the Sichuan basin provide paleogeothermal evidence for the existence and onset of the Emaishan mantle plume.ZHU ChuanQing XU Ming YUAN YuSon ZHAO YongQing SHAN JingNan HE ZhiGuo TIAN YunTao HU ShengBiao 2010Chinese Science Bulletin2010,55,10:30

11Improving bubble-particle attachment during the flotation of low rank coal by surface modification显示文摘Based on the problems caused by many oxygen-containing functional groups and poor floatability on the surface of low rank coal,the characteristics of low rank coal were analyzed systematically by means of scanning electron microscopy(SEM),X-ray diffraction(XRD)and X-Ray photoelectron spectroscopy(XPS)techniques.The bubble-particle induction time was used to determine the characterization of the bubble-particle attachment,and the bubble-particle attachment of low rank coal modified by soaking the coal samples in an acid or alkaline solution was analyzed.The floatability of the modified coal surface was verified by flotation tests.The results show that the particle size of 0.125–0.074 mm of the coal sample exhibited better bubble-particle attachment characteristics.The small bubble,the larger approach velocity of bubble and the larger bubble deformation were more helpful to enhance the bubbleparticle attachment.For an acid solution,the smaller the p H was and the longer the soaking time was,the better the floatability of the coal sample and the higher the combustible material recovery were.The combustible material recovery of low rank coal was increased to 78.79%by soaking the sample in an acid solution of pH=0 for 180 min.On the contrary there was a best concentration for the alkaline solution.Haishan Hu Ming Li Lulu Li Xiuxiang Tao 2020International Journal of Mining Science and Technology2020,30,2:27

13Implications of the immunoregulatory functions of mesenchymal stem cells in the treatment of human liver diseases显示文摘Transplantation of mesenchymal stem cells(MSCs)has been recently studied in animal models,and in clinical trials of patients with fulminant hepatic failure,end-stage liver diseases and inherited metabolic disorders.Modulatory cytokines produced by MSCs can inhibit immunocyte proliferation and migration to the liver,thereby attenuating inflammatory injury and reducing hepatocyte apoptosis.In addition,MSCs play an important role in regressing liver fibrosis and in supporting the function,proliferation and differentiation of endogenous hepatocytes under appropriate conditions.Although remarkable progress has been achieved in basic and clinical MSC studies,optimal therapeutic regimens for the clinical application of MSCs,such as optimal doses,transplantation routine and interval period for transplantation,need to be elucidated in detail.Furthermore,the long-term safety and therapeutic efficacy of MSC transplantation should be evaluated in future clinical trials.This review summarizes our current understanding of the immunomodulatory effects of MSC therapies on human liver diseases.Hu Lin Ruonan Xu Zheng Zhang Liming Chen Ming Shi Fu-Sheng Wang 2011Cellular & Molecular Immunology2011,8,1:26

15Report on Childhood Obesity in China (9): Sugar-sweetened Beverages Consumption and Obesity显示文摘Objective To explore the associations between sugar-sweetened beverage (SSB) consumption and obesity as well as obesity-related cardiometabolic disorders among children in China. Methods A total of 6974 (boys 3558, girls 3412) children aged 6-13 years participated in the study. Each participant's height, weight, waist circumference, fasting glucose, triglycerides, total cholesterol, high- density lipoprotein cholesterol, and low-density lipoprotein cholesterol were measured. The type of beverage consumption was determined using a self-administered questionnaire. Results SSBs were consumed regularly by 46.1% of the children. The prevalence [adjusted odds ratio (95% confidence internal (CI)] of obesity was 7.6% [as the reference group (ref.)], 10.1% [1.36(1.07, 1.74)], and 11.6% [1.46(1.21, 1.75)], among children who regularly drank milk, other beverages and SSBs, respectively. Regularly drinking SSBs elevated the likelihood of abdominal obesity [adjusted odds ratio (95% CI): 1.36 (1.17, 1.59)]. The prevalence [adjusted odds ratio (95% CI)] of obesity among children who regularly drank sports/caloric beverages, carbonated beverages, sweet tea, and plant protein beverages was 16.8% [2.00(1.31, 3.07)], 12.7% [1.52(1.23, 1.88)], 11.5% [1.52(1.18, 1.95)], and 10.4% [1.41(1.03, 1.94)], respectively, which was higher than that of regular milk drinkers [7.6 % (ref.)]. The prevalence [adjusted odds ratio (95% CI)] of abdominal obesity among children who regularly drank sweet tea, fruit/vegetable juices, and carbonated beverages was 17.7% [1.55(1.26, 1.90)], 16.2% [1.36(1.09, 1.70)], and 15.3% [1.24(1.03, 1.50)], respectively, which was much higher than that of regular milk drinkers [12.8% (ref.)]. Conclusions Regular SSB consumption was positively related to obesity and abdominal obesity. This relationship should be investigated further using a longitudinal study design.SHANG Xian Wen LIU Ai Ling ZHANG Qian HU Xiao Qi DU Song Ming MA Jun XU Gui Fa LI Ying GUO Hong Wei DU Lin LI Ting Yu MA Guan Sheng 2012Biomedical and Environmental Sciences2012,25,2:23
16TANDEM and GMAW Twin Wire Welding of Q690 Steel Used in Hydraulic Support显示文摘Compared with using semi-automatic gas shielded arc welding, using automatic TANDEM twin wire welding and twin wire gas metal arc welding (GMAW) to weld Q690 steel, a low-alloy high-strength structural steel used in the hydraulic support in the fully-mechanized mining face, the welding speed, deposition rate, production environment and welding quality can be obviously improved. Compared with GMAW twin wire welding, a refined microstructure in the weld and heat-affected zone (HAZ), narrow HAZ and improved joint strength were achieved with TANDEM on Q690. Also, due to the push-pull pulsed way in TANDEM welding, the droplet transfer, distribution on heat flow and interaction between two arcs were completely different from those in GMAW twin wire system. The heat input of TANDEM is only about 76.6% of GMAW, and correspondingly, the welding speed and welding seam can be obviously improved. The complete oscillation caused by TANDEM pulsed current occurred in the welding pool, which refined the grains in the microstructure. The results show that TANDEM twin wire welding is very suitable in the welding of Q690 used in the hydraulic support.FANG Chen-fu MENG Xiao-hui HU Qing-xian WANG Feng-jiang REN He WANG Hai-song GUO Yu MAO Ming 2012Journal of Iron and Steel Research(International)2012,19,5:22
17Ten cities cross-sectional questionnaire survey of children asthma and other allergies in China显示文摘Asthma,rhinitis and eczema(allergic or non-allergic)have increased throughout the world during the last decades,especially among children.Changes in the indoor environment are suspected to be important causes.China has experienced a dramatic change in indoor environmental exposures during the past two decades.However,such changes and their associations with children’s asthma and other health aspects have not been thoroughly studied.China,Children,Homes,Health(CCHH),Phase I,was a cross-sectional questionnaire survey of 48219 children 1–8 years old in 10 Chinese cities during 2010–2012.The questionnaire includes the International Study of Asthma and Allergies in Childhood(ISAAC)core health questions and additional questions regarding housing,life habits and outdoor environment.In health analyses,children aged 3–6 years old were included.The prevalences of doctor diagnosed asthma varied from 1.7%to 9.8%(mean 6.8%),a large increase from 0.91%in 1999 and 1.50%in2000.The prevalence of wheeze,rhinitis and atopic eczema(last 12 months)varied from 13.9%to 23.7%,24.0%to 50.8%and4.8%to 15.8%,respectively.Taiyuan had the lowest prevalences of all illnesses and Shanghai the highest,except for wheezewhere the highest value was for Urumqi.We found(1)no obvious association between disease prevalences and ambient PM10concentrations and(2)higher prevalences of disease in humid climates with hot summers and cold winters,but with no centrally heated buildings.Associations between the diseases and economic status as indexed by Gross Domestic Product(GDP)requires further study.ZHANG YinPing LI BaiZhan HUANG Chen YANG Xu QIAN Hua DENG QiHong ZHAO ZhuoHui LI AnGui ZHAO JiaNing ZHANG Xin QU Fang HU Yu YANG Qin WANG Juan ZHANG Ming WANG Fang ZHENG XiaoHong LU Chan LIU ZhiJian SUN YueXia MO JinHan ZHAO YiLi LIU Wei WANG TingTing NORBCK Dan BORNEHAG Carl-Gustaf SUNDELL Jan 2013Chinese Science Bulletin2013,58,34:22
18In-situ U-Pb dating of uraninite by fs-LA-ICP-MS显示文摘In this study,the Pb/U fractionation between zircon and uraninite during femtosecond Laser Ablation Inductively Coupled Plasma Mass Spectrometry(fs-LA-ICP-MS)analysis was studied in detail.The results show significant Pb/U fractionation between zircon and uraninite during fs-LA-ICP-MS analysis that when calibrated against the zircon standard M257,the obtained U-Pb age of the Chinese national uraninite standard GBW04420 is 17%older than the recommended value.Thus,the accurate in-situ U-Pb dating of uraninite by LA-ICP-MS requires matrix-matched external standards for calibration.Uraninite in thin sections of two U-mineralized leucogranite from the Gaudeanmus in Namibia was analyzed by a fs-LA-ICP-MS equipped with a Signal Smooth Device(SSD),using laser spot and frequency of 10μm and 1 Hz,respectively.When calibrated using GBW04420 as the external standard,two samples give weighted mean 206Pb/238U ages of 504±3 Ma(2σ,n=21)and503±3 Ma(2σ,n=22),and only one of two samples yields a concordia U-Pb age of 507±1 Ma(2σ,n=21).These results are consistent with ID-TIMS U-Pb ages of 509±1 and 508±12 Ma and are also indistinguishable from zircon U-Pb upper intercept ages of 506±33 Ma(2σ,n=29)and 501±51 Ma(2σ,n=29).The present study shows that in-situ U-Pb dating of uraninite can deliver more reliable formation ages of the deposit than dating coeval high-U zircon because the latter commonly suffer significant Pb loss after formation.Our results confirm that GBW04420 is an ideal matrix matching standard for in-situ U-Pb dating of uraninite.ZONG KeQing CHEN JinYong HU ZhaoChu LIU YongSheng LI Ming FAN HongHai MENG YanNing 2015Science China Earth Sciences2015,58,10:22
