| 1 | Assessment of duodenogastric reflux by combined continuous intragastric pH and bilirubin monitoring显示文摘AIM: To assess the diagnostic value of a combination of continuous intragastric pH and bilirubin monitoring in the detection of duodenogastric reflux (DGR), and the effects of diet on the bilirubin absorbance.METHODS: 30 healthy volunteers were divided into twogroups: standard diet group (Group 1) 18 cases, free diet group (Group 2) 12 cases. Each subjects were subjected to simultaneous 24 hour intragastric pH and spectrophotometric bilirubin concentration monitoring (Bilitec 2000).RESULTS: There was no difference of preprandial phasebilirubin absorbance between two groups. The absorbanceof postprandial phase was significantly increased in group 2than group 1. There was no difference between preprandialphase and postprandial phase absorbance in group 1.Postprandial phase absorbance was significantly higher ingroup 2. In a comparison of bile reflux with intragastric pHduring night time, there were 4 types of reflux:Simultaneous increase in absorbance and pH in only 19.6%, increase in bilirubin with unchanged pH 33. 3 %, pHincrease with unchanged absorbance 36. 3 %, and bothunchanged in 10. 8 %. Linear regression analysis showed nocorrelation between percertage total time of pH < 4 aridpercentage total time of absortance > 0. 14, r=0.068, P<0.05.CONCLUSION: Because of the dietary effect, highabsorbance fluids or foods should be avoided in detection.Intrsgastric pH and bilirubin monitoring separately predictthe presence of duodenal (and/or pancreatic) reflux and bilereflux. They can not substitute for each other. The detectionof DGR is improved if the two parameters are combinedsimultanoously. | Fei Dai Jun Gong Ru Zhang Jin-Yan Luo You-Ling Zhu Xue-Qin Wang,Department of Gastroenterology,Second Hospital of Xi’ an Jiaotong University,Xi’an 710004,Shaanxi Province,China | 2002 | World Journal of Gastroenterology2002，8，2： | 30 |
| 2 | Process mineralogy of Weishan rare earth ore by MLA显示文摘Mineral liberation analyser(MLA) was applied to quantitatively analyze the rare earth ore from Weishan in Shandong. Mineralogy parameters, such as mineral composition, occurrence states of rare earth elements(REEs) and valuable elements, mineral embedded grain size distribution, mineral association and liberation, are obtained. Results show that the contents of REEs and other valuable elements mainly contained in the ore were La 1.02 wt%, Ce 4.29 wt%, Pr 0.34 wt%, Nd 0.84 wt%, Sr 3.4 wt%and Ba 26.53 wt%, respectively. The REEs mainly occur in bastnaesite and carbocernaite in the form of independent mineral and the contents of bastnaesite and carbocernaite in the ore were 5.96 wt% and12.30 wt%, respectively. 67.34% of strontium occurs in carbocernaite and the rest occurs in celestobarite and strontianite mineral. 92.71% of barium occurs in barite. Liberation of main rare-earth minerals such as bastnaesite and carbocernaite is more than 80% when the grinding fineness is78.42% passing 74 μm. The research results could be employed to provide detailed basic theoretical data for further improvement of the beneficiation process flow and the processing index of rare earth ore, the recycling of other valuable minerals and the comprehensive utilization of tailings. | Caili Xu Chengbin Zhong Renliang Lyu Yaoyang Ruan Zhenyue Zhang Ru'an Chi | 2019 | Journal of Rare Earths2019，37，3： | 12 |
| 3 | Local concentration of middle and heavy rare earth elements in the col on the weathered crust elution-deposited rare earth ores显示文摘This present study focused on investigating the content and relative enrichment multiple of rare earth elements(REEs) in different terrain of weathered ore body, and the value of light rare earth elements/middle and heavy rare earth elements(LREEs/HREEs), in order to understand the mobilization and redistribution of HREEs, Furthermore, the abrasion pH was investigated as well, The results show that the average contents of HREEs in the knap, ridge and col are 37.26, 61.71, and 271.3 μg/g, respectively. The value of LREEs/HREEs is decreased from 16.78 to 7.914 between knap and col and the relative enrichment multiple of HREEs is as follows: C_(Col-HREEs) > C_(Ridge-HREEs) > 0. It is indicated the HREEs is concentrated in the col and the enrichment degree of HREEs is stronger than the ridge and the knap. Rare earth elements fractionation is exhibited in the different terrain of weathered ore body. Based on this study, the finding that HREEs concentrate in the lower terrain of weathered crust elution-deposited rare earth ores, such as in the col, would become a marker or indicator to search for middle and heavy rare earth enriched zone. | Zhenyue Zhang Ningjie Sun Zhengyan He Ru'an Chi | 2018 | Journal of Rare Earths2018，36，5： | 10 |
| 4 | Enhancing mineral liberation of a Canadian rare earth are with microwave pretreatment显示文摘Liberation. as an attribute of mineralogy characteristic. whose impacts on finely disseminated Canadian rare earth ore was studied with microwave pretreatment. Samples of a light rare earth ore along with mostly ankerite and biotite as dominant gangue minerals as well as bastnaesite, strontianite and goethite as dominated minerals were exposed to further comminution by ball mill and microwave pretreatment fragmentation. Mineralogical characteristics were analyzed by using a mineral liberation analyzer(MLA).The results indicated that tight association mutually penetrates among dominated minerals in the range size of -300 + 212 μm and 212 + 150 μm and gangue minerals in the form of adjacent type. fine vein type. shell type and packing type. Temperature in the ore samples pre-treated by microwave can rapidly rise to 250 ℃ with microwave power of 0-1.5 kW and microwave time of 0-2 min. Applying the microwave pretreatment merely reduces the hardness of the ore causing the fracture of rare earth ore, but this does not transform or change the original mineralogy characteristics of the ore samples. On the basis of above study. the liberation value of bastnaesite, strontianite and goethite with microwave pretreatment is greater than with conventional comminution when the liberation class is above 75%. The distribution of particle size of rare earth ore samples is better with microwave pretreatment than with conventional comminution for particle size of 7.4 × 10^(-5) m. With microwave pretreatment, the theoretical grade-recovery of bastnaesite. strontianite and goethite in the rare earth ore attains better results than with conventional comminution at a given grade. | Chengbin Zhong Caili Xu Renliang Lyu Zhenyue Zhang Xiaoyan Wu Ru'an Chi | 2018 | Journal of Rare Earths2018，36，2： | 10 |

| 6 | Partitioning properties of rare earth ores in China显示文摘The properties of rare earth partitioning in Chinese industrial rare earth ores were analyzed. Rare earth ores canbe divided into the single-mineral type ore with bastnaesite, the multi-mineral type ore with bastnaesite and monazite, andthe weathering crust type. Both the Bayan Obo rare earth ore and the Zhushan rare earth ore are a kind of mixed ore, con-sisting of bastnaesite and monazite. Their rare earth partitionings are strongly enriched in light rare earths, where CeO2 is50% and the light rare earth partitioning is totally over 95%. The Mianning rare earth ore as well as the Weishan rare earthis a kind of rare earth ore only having bastnaesite. Their rare earth partitionings are also strongly enriched in light rare earths,in which CeO2 is 47% and the light rare earth partitioning is totally over 94%. For the weathering crust type rare earth ore,there are the Longnan rare earth ore, the Xunwu rare earth ore, and the middle yttrium and rich europium ore. In the Long-nan rare earth ore, which is strongly enriched in heavy rare earths, Y2O3 is 64.83%, and the heavy and light rare earthpartitionings are 89.40% and 10.53%, respectively. In the Xunwu rare earth ore, which is strongly enriched in light rareearths, CeO2 is 47.16%, and the light rare earth partitioning is totally 93.25%. Y and Eu are enriched in the middle yttriumand rich europium ore. Its middle rare earth partitioning is totally over 10%, and Eu2O3 and Y2O3 are over 0.5% and 20%,respectively, which are mainly industrial resources of the middle and the heavy rare earths. | CHI Ru 'an LI Zhongjun PENG Cui ZHU Guocai XU Shengming | 2005 | Rare Metals2005，24，3： | 8 |

| 14 | Urban-rural disparities in mild cognitive impairment and its functional subtypes among community- dwelling older residents in central China显示文摘background Substantial variations in the prevalence of mild cognitive impairment(MCI)and its subtypes have been reported,although mostly in geographically defined developed countries and regions.Less is known about MCI and its subtypes in rural areas of less developed central China.Aims The study aimed to compare the prevalence of MCI and its subtypes in residents aged 65 years or older in urban and rural areas of Hubei Province,China.Methods Participants aged 65 years or older were recruited between 2018 and 2019.Inperson structured interviews and clinical and neuropsychological assessments were performed at city health community centres and township hospitals.results Among 2644 participants without dementia,735 had MCI,resulting in a prevalence of 27.8%for total MCI,20.9%for amnestic MCI(aMCI)and 6.9%for non-amnestic MCI(naMCI).The prevalence of MCI in urban and rural areas was 20.2%and 44.1%,respectively.After adjusting for demographic factors,the prevalence of total MCI,aMCI and naMCI differed significantly between rural and urban areas(adjusted odds ratio(OR)2.10,1.44 and 3.76,respectively).Subgroup analysis revealed an association between rural socioeconomic and lifestyle disadvantage and MCI and its subtypes.Conclusions Our findings suggest that the prevalence of MCI among urban residents in central China is consistent with that in other metropolis areas,such as Shanghai,but the prevalence in rural areas is twice that in urban areas.Prospective studies and dementia prevention in China should focus on rural areas. | Dan Liu Lin Li Lina An Guirong Cheng Cong Chen Mingjun Zou Bo Zhang Xuguang Gan Lang Xu Yangming Ou Qingming Wu Ru Wang Yan Zeng | 2021 | General Psychiatry2021，34，5： | 3 |
| 15 | Low power and high uniformity of HfO_x-based RRAM via tip-enhanced electric fields显示文摘In this paper, the HfO_x-based resistive random access memory(RRAM) devices with sub-100 nm pyramid-type electrodes were fabricated. With the help of tip-enhanced electric field around the pyramid-type electrodes, it was experimentally demonstrated that the novel devices have better cycle-to-cycle variation control, lower forming/set voltage(1.97/0.7V) and faster switching speed(≤30 ns under 0.9V pulse) as well as better endurance reliability than conventional flat electrode resistive memory devices. In addition,the novel RRAM is experimentally demonstrated with independence of electrode number for the first time to present great potential in scaling down. This novel structure metal-oxide based RRAM will be suitable for the future low-power non-volatile memory application. | Xiaokang LI Baotong ZHANG Bowen WANG Xiaoyan XU Yuancheng YANG Shuang SUN Qifeng CAI Shijie HU Xia AN Ming LI Ru HUANG | 2019 | Science China(Information Sciences)2019，62，10： | 3 |
