| 1 | 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 |
| 2 | Evaluation of the reliability of twin variant analysis in Mg alloys by in situ EBSD technique显示文摘Electron backscatter diffraction(EBSD)is an orientation mapping technique,which has been widely used to study texture evolution and twinning behavior.This work aims to study the variant of{10¯12}twins during tensile deformation of AZ31 Mg alloys.An in-situ tensile stage was used,and coupled with EBSD technique,the variants of twins can be analyzed without releasing the tensile stress.Based on the EBSD maps,the first and second smallest misorientation angles(M_(1)and M 2)between each active twin and respective potential variants were calculated,and the distribution of M_(1)values with tensile strain was obtained.The results indicated that{10¯12}twins were deviated from their ideal orientations with strain increased.The criteria of M_(1)<4°and M 2−M_(1)>2°were suggested to be applied to select the data points for reliable variant identification.Moreover,it confirmed that the deviation of twin relationship was ascribed to the profuse basal glide in matrices and/or twins. | Feiya Liu Changfa Guo Renlong Xin Guilin Wu Qing Liu | 2019 | Journal of Magnesium and Alloys2019，7，2： | 2 |

| 4 | Aortic reoperation in a patient with Loeys-Dietz syndrome显示文摘Loeys-Dietz syndrome (LDS,OMIM #609192) is a recently recognized connective tissue disorder with clinical characteristics similar to Marfan syndrome.Aggressive aortic pathologies in LDS makes timely diagnosis and surgical intervention crucial compared to other genetic syndromes.We report a young man with LDS confirmed by genetic testing who twice underwent surgical operations to repair aortic aneurysm. In August 2000,a 14-year-old boy was admitted to our institute with significant aortic regurgitation.Preoperative echocardiogram revealed an aortic root aneurysm 5 cm in diameter and severe aortic insufficiency.He underwent composite graft replacement (Bentall procedure) with a 27 mm Medtronic Hall valved conduit (Medtronic,Inc.,Minneapolis,MN,USA).He had an uneventful postoperative course and was discharged after nine days. | Wang Chunsheng Li Jun Lai Hao Sun Yongxin Guo Changfa Yin Kanhua Zhu Kai | 2014 | Chinese Medical Journal2014，，12： | 1 |
| 5 | STUDY ON THE DESALINATION BEHAVIORS OF PA/PSF THIN FILM COMPOSITE显示文摘A polypiperazine amide (PA)/polysulfone (PSF) thin film composite (TFC) was prepared by interfacial polymerization (IP) using a trimesoyl chloride hexane solution as the oil phase and a piperazine aqueous solution as the water phase on a porous polysulfone hollow fiber substrate. Its separating behaviors were investigated systematically to various salts such as NaCl, KCl, Na2SO4, MgCl2, CaCl2 and MgSO4, showing the highest rejection rate to Na2SO4, the second to MgSO4, the third to MgCl2 and CaCl2, and the lowest to KCl, NaCl, being 99%, 98%, 70%, 60%, 15% and 10% respectively. Under an increasing pressure or with time, the rejection rate of the TFC rises to a plateau. To various concentration of the feed, the rejection rate reduced gradually with the higher concentration. | TIAN Guojun ZHANG Yufeng ZHANG Yan DU Qiyun XIAO Changfa GUO Hao | 2006 | Chinese Journal of Reactive Polymers2006，15，2： | 1 |
