| 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 | Progress and significance in research on the early Middle Cambrian Kaili Biota, Guizhou Province, China显示文摘Important progress in research on the Kaili Biota has been made recently. Many interesting components from Chengjiang Biota and Burgess Shale Biota have been discovered, e.g. Microdictyon of lobopodia; Ottoia, Palaeoscolex of worms; Naraoia, Marrella of Trilobitioidea, Mollisonia, anamalocarids and other non-trilobite arthropods; and new sorts of echinoder-mas, macroalage fossils and so on. Recent work on the Kaili Biota has resulted in the following developments: (i) an increase in the number of animal genera, up to more than 100 genera in total, so that the Kaili Biota has become the third most diverse of the Burgess Shale-type Biota after the Burgess Shale and Chengjiang Biotas; and (ii) the most noteworthy fossils in the Kaili Biota are echinoderms, non-trilobite arthropods and soft-bodied medusiform fossils, especially the most diverse echinoderms. The progress provides envidence for the biodiversity of marine organisms presented after the 'Cambrian Explosion' and serves as a link between the earlist Cambrian Chengjiang Biota and late early Middle Cambrian Burgess Shale Biota. It is of great significance in the reconstruction of the Cambrian palaeoplate, palaeongeography and in research on taphonomy. | ZHAO Yuanlong, YUAN Jinliang, ZHU Maoyan, YANG Ruidong, GUO Qingjun, PENG Jin and YANG Xinglian(1.

| 3 | Improved esophageal squamous cell carcinoma screening effectiveness by risk-stratified endoscopic screening:evidence from high-risk areas in China显示文摘Background:Risk-stratified endoscopic screening(RSES),which offers endoscopy to those with a high risk of esophageal cancer,has the potential to increase effectiveness and reduce endoscopic demands compared with the universal screening strategy(i.e.,endoscopic screening for all targets without risk prediction).Evidence of RSES in high-risk areas of China is limited.This study aimed to estimate whether RSES based on a 22-score esophageal squamous cell carcinoma(ESCC)risk prediction model could optimize the universal endoscopic screening strategy for ESCC screening in high-risk areas of China.Methods:Eight epidemiological variables in the ESCC risk prediction model were collected retrospectively from 26,618 individuals aged 40-69 from three high-risk areas of China who underwent endoscopic screening betweenMay 2015 and July 2017.The model’s performance was estimated using the area under the curve(AUC).Participants were categorized into a high-risk group and a low-risk group with a cutoff score having sensitivities of both ESCC and severe dysplasia and above(SDA)at more than 90.0%.Results:The ESCC risk prediction model had an AUC of 0.80(95% confidence interval:0.75-0.84)in this external population.We found that a score of 8(ranging from 0 to 22)had a sensitivity of 94.2% for ESCC and 92.5% for SDA.The RSES strategy using this threshold score would allow 50.6% of endoscopies to be avoided and save approximately US$0.59 million compared to universal endoscopic screening among 26,618 participants.In addition,a higher prevalence of SDA(1.7%vs.0.9%),a lower number need to screen(60 vs.111),and a lower average cost per detected SDA(US$3.22 thousand vs.US$5.45 thousand)could have been obtained by the RSES strategy.Conclusions:The RSES strategy based on individual risk has the potential to optimize the universal endoscopic screening strategy in ESCC high-risk areas of China. | He Li Chao Ding Hongmei Zeng Rongshou Zheng Maomao Cao Jiansong Ren Jufang Shi Dianqin Sun Siyi He Zhixun Yang Yiwen Yu Zhe Zhang Xibin Sun Guizhou Guo Guohui Song Wenqiang Wei Wanqing Chen Jie He | 2021 | Cancer Communications2021，41，8： | 3 |

| 5 | Study on the Electrical Conductivity of 0.025 mol NaCl Solution at 0.25-3.75 GPa and 20-370℃显示文摘The electrical conductance of 0.025 mol NaCl solution was measured at0.25-3.75 GPa and 20-370℃. As shown by the results, the conductance increases with temper-ature, and there is a liner relation between the reciprocal of temperature and the logarithm ofthe conductance but their slopes are different at different pressures. The relations between theconductance and pressure is rather complex and there are some discontinuities: in the range of2.25-3.75 GPa, the conductance increases with the pressure; in the range of 1.25-2.0 GPa, theconductance is not related to the pressure; and at a pressure of 0.75 GPa, the conductance ishigher than that at the pressures nearby. This reflects that the NaCl solution has rather differentproperties of electronic chemistry at various pressures, and probably is an important cause forthe existence of the layers with high electrical conductance and low velocity in the Earth’s crustand mantle. | Zheng Haifei Xie Hongsen Xu Yousheng Song Maoshuang Guo Jie and Zhang Yueming Earth’s Interior Material Laboratory,Institute of Geochemistry,Chinese Academy of Sciences,Guiyang,Guizhou | 1997 | Acta Geologica Sinica(English Edition)1997，71，3： | 1 |
| 6 | Hydrothermal sedimentaion of Wengfu phosphorite deposit显示文摘THE Wengfu phosphorite deposit, a superlarge ore deposit, is located in the counties of Weng an andFuquan, Central Guizhou, China. The deposit has been considered as typical sedimentary one since itwas found, but our new approach suggests that its formation be related to contemporaneous submarine hydrothermal activity. The Wengfu phospohorite deposit, belonging to Doushantuo stage of Late Sinian (Latest Precambrian), was divided into two ore layers intercalated by dolomites and siliceous rocks. In the phosphoritesthere exist abundant fossils, including newly found 'Weng an Biota' which contain the fossils of multicellular thallophytes as well as animal embryos and sponges. Besides the common sedimentary structures, the phosphorites and the coexisting siliceous rocks alsopossess obvious hydrothermal sedimentation features, which are presented as the following: (i) The coexisting cherts are, lenticular in distribution and with high SiO2 purity and high homogeneous temperatures (up to 150℃) of the inclusions, characterized by hydrothermal sedimentation. (ii) The special 'pellets' or 'pisolites' formed by hydrothermal eruption are common in the phos- | YANG Weidong~1, CHEN Nansheng~1, WANG Xingli~1, GAO Liping~1, ZHAO Yuanlong~2 and GUO Qingjun~2 1.
