1Genomic evidence of lung carcinogenesis associated with coal smoke in Xuanwei area, China显示文摘Xuanwei area, in southwestern China,harbors the highest female lung cancer rate in the country(Supplementary Table 1) [1]. Epidemiological studies have shown that lung cancer incidence in Xuanwei area is associated with the use of different types of local coal for household cooking and heating [2]. The genomic landscape of Xuanwei female adenocarcinoma(XWFA), the most distinctive feature of lung cancer in Xuanwei, has yet to be elucidated systematically. Here,we provide the fundamental resource of genomic datasets for further exploration of XWFA molecular mechanisms and development of targetable therapy.Honglei Zhang Chao Liu Li Li Xu Feng Qing Wang Jihua Li Shaobin Xu Shuting Wang Qianlu Yang Zhenghai Shen Jinhua Su Xiaosan Su Ruifen Sun Xuhong Zhou Junliang Wang Yongchun Zhou Baowei Jiao Wanbao Ding Xianbao Cao Yue Wang Yunchao Huang Lianhua Ye 2021National Science Review2021,8,12:2

3Distribution Assessment and Source Identification Using Multivariate Statistical Analyses and Artificial Neutral Networks for Trace Elements in Agricultural Soils in Xinzhou of Shanxi Province, China显示文摘Multivariate statistical analyses were used to assess the contents and distributions of trace elements in agricultural soils in Xinzhou of Shanxi Province, China, and to identify their sources. Samples with high levels of trace elements were concentrated in eastern Xinzhou, with contents declining from the east to west. Principal component and redundancy analyses revealed strong correlations among Co, Cu, Mn, Ni, Se, V, and Zn contents, suggesting that these elements were derived from similar parent materials. There were also strong correlations between the contents of these elements and soil properties. Contents of Cd and Pb were significantly higher in the agricultural soil samples than in the background soil samples(P < 0.05), and were higher in areas with higher levels of gross domestic product but decreased with distance to the nearest road. Therefore, human activities appear to have a strong influence on the Cd and Pb distribution patterns. A novel artificial neural network(ANN) model, using environmental input data, was used to predict the soil Cd and Pb contents of specified test dates. The performances of the ANN model and a traditional multilinear model were compared. The ANN model could successfully predict Cd and Pb content distributions, projecting that soil Cd and Pb contents will increase by 128% and 25%, respectively, by 2020. The results thus indicated that the economic condition of an area has a greater effect on trace element contents and distributions in the soil than the scale of the economy itself.SHANGGUAN Yuxian CHENG Bin ZHAO Long HOU Hong MA Jin SUN Zaijin XU Yafei ZHAO Ruifen ZHANG Yigong HUA Xiaozan HUO Xiaolan ZHAO Xiufeng 2018Pedosphere2018,28,3:1
4Photon Dose Calculation Method Based on Monte Carlo Finite-Size Pencil Beam Model in Accurate Radiotherapy显示文摘This study mainly focused on the key technologies,the photon dose calculation based on the Monte Carlo Finite-Size Pencil Beam(MCFSPB)model in the Accurate Radiotherapy System(ARTS).In the MCFSPB model,the acquisition of pencil beam kernel is one of the most important technologies.In this study,by analyzing the demerits of the clinical pencil beam dose calculation methods,a new pencil beam kernel model was developed based on the Monte Carlo(MC)simulation and the technology of medical accelerator energy spectrum reconstruction.which greatly improved the accuracy of calculated result.According to the axial symmetry principle,only part of simulation results was used for the data of pencil beam kernel,which greatly reduced the data quantity of the pencil beam and reduced calculated time.Based on the above studies,the MCFSPB method was designed and implemented by the Visual C++development tool.With several tests including the comparisons among the American Association of Physicists in Medicine(AAPM)No.55 Report sample and the ion chamber measurement of lung-simulating inhomogeneous phantom in clinical treatment plan,the results showed that the maximum error of most calculated point was less than 0.5%in the homogeneous phantom and less than 3%in the heterogeneous phantom.This method met the clinical criteria,and would be expected to be used as a fast and accurate dose engine for clinic TPS.Huaqing Zheng Guangyao Sun Gui Li Ruifen Cao Xi Pei Liqin Hu Gang Song Yican Wu 2013Communications in Computational Physics2013,14,10:0
