| 1 | Antimony(V) removal from water by iron-zirconium bimetal oxide: Performance and mechanism显示文摘A Fe-Zr binary oxide adsorbent has been successfully synthesized using a co-precipitation method. It showed a better performance for antimonate (Sb(V)) removal than zirconium oxide or amorphous ferric oxide. The experimental results showed that the Fe-Zr adsorbent has a capacity of 51 mg/g at an initial Sb(V) concentration of 10 mg/L at pH 7.0. Sb(V) adsorption on the Fe-Zr bimetal oxide is normally an endothermic reaction. Most of the Sb(V) adsorption took place within 3 hr and followed a pseudo second-order rate law. Co-existing anions such as SO42- , NO3- and Cl- had no considerable effects on the Sb(V) removal; PO34 had an inhibitory effect to some extent at high concentration; while CO32- and SiO44- showed significant inhibitory effects when they existed in high concentrations. The mechanism of Sb(V) adsorption on the adsorbent was investigated using a combination of zeta potential measurements, XPS, Raman, FT-IR observations and SO42- release determination. The ionic strength dependence and zeta potential measurements indicated that inner-sphere surface complexes were formed after Sb(V) adsorption. Raman and XPS observations demonstrated that both Fe-OH and Zr-OH sites at the surface of the Fe-Zr adsorbent play important roles in the Sb(V) adsorption. FT-IR characterization and SO42- release determination further demonstrated that the exchange of SO42- with Sb(V) also could promote the adsorption process. In conclusion, this adsorbent showed high potential for future application in Sb(V) removal from contaminated water. | Xuehua Li Xiaomin Dout Junqing Li | 2012 | Journal of Environmental Sciences2012，24，7： | 21 |

| 3 | Failure laws of narrow pillar and asymmetric control technique of gob-side entry driving in island coal face显示文摘In allusion to the problems of complex stress distribution in the surrounding rock and deformation failure laws, as well as the difficulty in roadway supporting of the gob-side entry driving in the island coal face, 2107 face in Chengjiao Colliery is researched as an engineering case. Through physical mechanical test of rock, theoretical and numerical simulation analyses of rock, the analysis model of the roadway overlying strata structure was established, and its parameters quantified. To reveal the deformation law of the surrounding rock, the stability of the overlying strata structure was studied before, during and after the roadway driving. According to the field conditions, the stress distribution in coal pillar was quantified, and the surrounding rock deformation feature studied with different widths of the pillars in gob-side entry driving. Finally, the pillar width of 4 m was considered as the most reasonable. The research results show that there is great difference in support conditions among roadway roof, entity coal side and narrow pillar side. Besides, the asymmetric control technique for support of the surrounding rock was proposed. The asymmetric control technique was proved to be reasonable by field monitoring, support by bolt-net, steel ladder and steel wire truss used in narrow pillar side. | Yang Jiping Cao Shenggen Li Xuehua | 2013 | International Journal of Mining Science and Technology2013，23，2： | 16 |
| 4 | CCL5 deficiency promotes liver repair by improving inflammation resolution and liver regeneration through M2 macrophage polarization显示文摘Despite the diverse etiologies of drug-induced liver injury(DILI),innate immunity activation is a common feature involved in DILI progression.However,the involvement of innate immunity regulation in inflammation resolution and liver regeneration in DILI remains obscure.Herein,we identified the chemokine CCL5 as a central mediator of innate immunity regulation in the pathogenesis of DILI.First,we showed that serum and hepatic CCL5 levels are elevated in both DILI patients and an APAP-induced liver injury(AILI)mouse model.Interestingly,both nonparenchymal cells and stressed hepatocytes are cell sources of CCL5 induction in response to liver injury.Functional experiments showed that CCL5 deficiency has no effect on the early phase of AILI but promotes liver repair in the late phase mainly by promoting inflammation resolution and liver regeneration,which are associated with an increased number of hepatic M2 macrophages.Mechanistically,CCL5 can directly activate M1 polarization and impede M2 polarization through the CCR1-and CCR5-mediated activation of the MAPK and NF-κB pathways.We then showed that CCL5 inhibition mediated by either a CCL5-neutralizing antibody or the antagonist Met-CCL5 can greatly alleviate liver injury and improve survival in an AILI mouse model.Our data demonstrate CCL5 induction during DILI,identify CCL5 as a novel innate immunity regulator in macrophage polarization,and suggest that CCL5 blockage is a promising therapeutic strategy for the treatment of DILI. | Meng Li Xuehua Sun Jie Zhao Lei Xia Jichang Li Min Xu Bingrui Wang Han Guo Chang Yu Yueqiu Gao Hailong Wu Xiaoni Kong Qiang Xia | 2020 | Cellular & Molecular Immunology2020，17，7： | 13 |
| 5 | Development of fractures in soft rock surrounding a roadway and their control显示文摘As the excavation of roadway,new fractures will be formed and the pre-existing fractures extend with the redistribution of stress in surrounding rocks.Eventually,fracture zone and bed separation are formed in rocks because of the developed fractures.Therefore,mastering the fracture evolution of surrounding rocks is very important to maintain the stability of roadway.The surrounding rocks of main haulage roadway in a certain coal mine is so broken and loose that the supporting is very difficult.Based on comprehensive analysis of the engineering geological conditions,a sight instrument was used to observe the fractures of internal surrounding rocks.Four indices,i.e.,the width of fracture zone W,the number of fractures n,the width of fractures d and rock fracture designation RFD,are put forward to evaluate the fracture development.According to the evolution rules of the soft rock roadway from this paper,control principles by stages and by regions are presented through the research.At the same time,the best time of grouting reinforcement is determined on the basis of fracture saturation.Field practice shows that the roadway can satisfy normal production during service periods by suitable first support and grouting reinforcement. | Li Xuehua Yao Qiangling Man Jiankang Chen Chaoqun He Lihui | 2011 | Mining Science and Technology2011，21，4： | 12 |
| 6 | Low-Level Temperature Inversions and Their Effect on Aerosol Condensation Nuclei Concentrations under Different Large-Scale Synoptic Circulations显示文摘Knowledge of the statistical characteristics of inversions and their effects on aerosols under different large-scale synoptic circulations is important for studying and modeling the diffusion of pollutants in the boundary layer. Based on results generated using the self-organizing map(SOM) weather classification method, this study compares the statistical characteristics of surface-based inversions(SBIs) and elevated inversions(EIs), and quantitatively evaluates the effect of SBIs on aerosol condensation nuclei(CN) concentrations and the relationship between temperature gradients and aerosols for six prevailing synoptic patterns over the the Southern Great Plains(SGP) site during 2001–10. Large-scale synoptic patterns strongly influence the statistical characteristics of inversions and the accumulation of aerosols in the low-level atmosphere. The activity,frequency, intensity, and vertical distribution of inversions are significantly different among these synoptic patterns. The vertical distribution of inversions varies diurnally and is significantly different among the different synoptic patterns. Anticyclonic patterns affect the accumulation of aerosols near the ground more strongly than cyclonic patterns. Mean aerosol CN concentrations increase during SBIs compared to no inversion cases by 16.1%, 22.6%, 24.5%, 58.7%, 29.8% and 23.7% for the six synoptic patterns. This study confirms that there is a positive correlation between temperature gradients and aerosol CN concentrations near the ground at night under similar large-scale synoptic patterns. The relationship is different for different synoptic patterns and can be described by linear functions. These findings suggest that large-scale synoptic patterns change the static stability of the atmosphere and inversions in the lower atmosphere, thereby influencing the diffusion of aerosols near the ground. | LI Jun CHEN Hongbin Zhanqing LI WANG Pucai Maureen CRIBB FAN Xuehua | 2015 | Advances in Atmospheric Sciences2015，32，7： | 12 |
| 7 | INTERFACIAL ADHESION AND MECHANICAL PROPERTIES OF PMMA-COATED CaCO_(3)NANOPARTICLE REINFORCED PVC COMPOSITES显示文摘Polymethyl methacrylate (PMMA)-coated nano-CaCO3 particles were prepared by in-situ emulsion po- lymerization. The mechanical properties of nano-CaCO3 particles-reinforced PVC were investigated using an AG-2000A universal testing machine and an XJU-2.75 izod impact tester; interfacial adhesion between CaCO3 nanoparticles and PVC matrix by SEM, and structure of PMMA coated on the surface of CaCO3 by FTIR and H-NMR. The results indicate 1 that the PMMA coated on the nano CaCO3 particles consists mainly of syndiotactic structure, and their three tacticity contents were rr 52.8%, mm 7.3% and mr 39.9%, respectively. The interfacial adhesion between CaCO3 nanoparticles and PVC matrix was significantly improved when the CaCO3 nanoparticles were coated with PMMA, which led to in- creased Young’s moduli and tensile strengths of the PMMA-coated CaCO3/PVC composites. The izod impact strengths of the composites were strongly affected by the PMMA coating thickness and increased significantly with increasing the volume fraction of CaCO3 filler in the composites. | Xuehua Chen Chunzhong Li Shoufang Xu Ling Zhang Wei Shao H.

| 8 | A comparative study on source apportionment of polycyclic aromatic hydrocarbons in sediments of the Daliao River,China:Positive matrix factorization and factor analysis with non-negative constraints显示文摘Two receptor models,positive matrix factorization (PMF) and factor analysis with non-negative constraints (FA-NNC),were applied for source apportionment of polycyclic aromatic hydrocarbons (PAHs) in sediments of the Daliao River,China.The source profiles and source contributions derived from the two receptor models were comparable.For PMF,PAHs mainly came from coal combustion (43.3%),followed by biomass burning (24.3%),traffic emissions (16.7%) and coke oven (15.7%).As for FA-NNC,coal combustion (50.4%) was dominant,followed by biomass burning (21.9%),traffic emission (15.7%) and coke oven (12.0%).The source apportionment results are consistent with the results from the specific PAH diagnostic ratios and emission inventory analysis.In addition,the source apportionment results are consistent with the structure of energy material usage in Liaoning Province of China. | LIU ChunHui TIAN FuLin CHEN JingWen LI XueHua QIAO XianLiang | 2010 | Chinese Science Bulletin2010，55，10： | 10 |
| 9 | Progress and perspectives of quantitative structure-activity relationships used for ecological risk assessment of toxic organic compounds显示文摘Structure-activity relationship (SAR) and quantitative structure-activity relationship (QSAR), collec- tively referred to as (Q)SARs, play an important role in ecological risk assessment (ERA) of organic chemicals. (Q)SARs can fill the data gap for physical-chemical, environmental behavioral and ecotoxicological parameters of organic compounds; they can decrease experimental expenses and reduce the extent of experimental testing (especially animal testing); they can also be used to assess the uncertainty of the experimental data. With the development for several decades, (Q)SARs in envi- ronmental sciences show three features: application orientation, multidisciplinary integration, and in- telligence. Progress of (Q)SAR technology for ERA of toxic organic compounds, including endpoint selection and mathematic methods for establishing simple, transparent, easily interpretable and portable (Q)SAR models, is reviewed. The recent development on defining application domains and diagnosing outliers is summarized. Model characterization with respect to goodness-of-fit, stability and predictive power is specially presented. The purpose of the review is to promote the development of (Q)SARs orientated to ERA of organic chemicals. | CHEN JingWen LI XueHua YU HaiYing | 2008 | Science China Chemistry2008，51，7： | 9 |

| 11 | Synthesis and catalytic performance of macroporous La1-xCexCoO3 perovskite oxide catalysts with high oxygen mobility for catalytic combustion of soot显示文摘The disordered macroporous-mesoporous La1-xCexCoO3 catalysts were prepared by complexcombustion method with ethylene glycol as complexing agent at relatively low calcination temperature.The samples were characterized by means of X-ray diffraction,N2 adsorption-ndash;desorption,Xray photoelectron spectroscopy,transmission electron microscopy,hydrogen temperature-programmed reduction and soot temperature-programmed reduction,and so on.The results show that the use of complexing agent and relatively low calcination temperature increase the specific surface area of the catalyst and have abundant pore structure.The Ce ions introduced into lattice of LaCoO3 mainly exist in the form of tetravalent.At the same time,Ce ions enhance the redox performance of the catalyst and the mobility of active oxygen species,which enhances the catalytic activity of the catalyst for soot combustion.The results of activity test show that La0.9Ce0.1CoO3 catalyst exhibits the highest activity in the absence of NO and NO2,and its T10,T50 and T90 are 371,444,and 497℃,respectively.At the same time,a possible reaction mechanism is proposed in this study based on the turnover frequency(TOF) calculated by isothermal anaerobic titrations,XPS and XRD results. | Jiachen Sun Zhen Zhao Yazhao Li Xuehua Yu Linlin Zhao Jianmei Li Yuechang Wei Jian Liu | 2020 | Journal of Rare Earths2020，38，6： | 8 |
| 12 | Reworking effects in the Holocene Zhuye Lake sediments:A case study by pollen concentrates AMS ^(14)C dating显示文摘Transported by wind and water,the relatively old sediments can deposit in the terminal lake of an inland drainage basin.The reworking effect can affect the lake sediments 14 C dating and explanations for proxies.The Zhuye Lake is the terminal lake of the Shiyang River Basin.Previous studies indicated that sediments in different locations of the lake basin showed different climatic change patterns.And then,some radiocarbon dates were inverted for some Late Pleistocene sections.Whether this phenomenon is related with the reworking effect? The pollen concentrates 14 C dating can avoid the reservoir effect,which is an ideal method for studying the reworking effect.In this study,we used the pollen concentrates as dating materials and dated five Holocene sections in the Zhuye Lake Basin.Based on the 14 C dates comparison between the pollen concentrates,organic matter,and shells,the pollen concentrates dates are relatively older than other dating materials.Based on the result,the reworking effect worked in the Zhuye Lake Basin during the Holocene;however,in different locations of the lake basin the reworking effects were in different levels.Furthermore,the Holocene lacustrine deposits were formed mostly during the early and middle Holocene.This study provided clues for reworking effect studies of other lakes in arid China. | LIYu WANG NaiAng LI ZhuoLun ZHANG ChengQi ZHOU XueHua | 2012 | Science China Earth Sciences2012，55，10： | 7 |
| 13 | Cytotoxicity of the soluble and insoluble fractions of atmospheric fine particulate matter显示文摘Inhaled atmospheric fine particulate matter(PM2.5)includes soluble and insoluble fractions,and each fraction can interact with cells and cause adverse effects.PM2.5 samples were collected in Jinan,China,and the soluble and insoluble fractions were separated.According to physiochemical characterization,the soluble fraction mainly contains watersoluble ions and organic acids,and the insoluble fraction mainly contains kaolinite,calcium carbonate and some organic carbon.The interaction between PM2.5 and model cell membranes was examined with a quartz crystal microbalance with dissipation(QCM-D)to quantify PM2.5 attachment on membranes and membrane disruption.The cytotoxicity of the total PM2.5 and the soluble and insoluble fractions,was investigated.Negatively charged PM2.5 can adhere to the positively charged membranes and disrupt them.PM2.5also adheres to negatively charged membranes but does not cause membrane rupture.Therefore,electrostatic repulsion does not prevent PM2.5 attachment,but electrostatic attraction induces remarkable membrane rupture.The human lung epithelial cell line A549 was used for cytotoxicity assessment.The detected membrane leakage,cellular swelling and blebbing indicated a cell necrosis process.Moreover,the insoluble PM2.5 fraction caused a higher cell mortality and more serious cell membrane damage than the soluble fraction.The levels of reactive oxygen species(ROS)enhanced by the two fractions were not significantly different.The findings provide more information to better understand the mechanism of PM2.5 cytotoxicity and the effect of PM2.5 solubility on cytotoxicity. | Ling Liu Qiuhua Zhou Xuezhi Yang Gang Li Jingzhu Zhang Xuehua Zhou Wei Jiang | 2020 | Journal of Environmental Sciences2020，32，5： | 4 |
| 14 | Time-domain characteristics of overlying strata failure under condition of longwall ascending mining显示文摘Ascending mining is one of the most effective ways to solve problems of water inrush, gas outburst and rock burst in coal seams mining. In order to reveal the law of motion and spatiotemporal relationship of overlaying strata, field measurement has been done in a mine. Long distance drillings were constructed from 4# coal seam to 6# coal seam at several certain typical positions, and movement and failure law of overlying strata after mining was analyzed by drilling video and observing the fluid leakage. Besides, we also analyzed the spatiotemporal development law of overlying strata failure with different mining heights and time intervals in the lower coal seam. The results show that: ascending mining is significantly affected by time-domain characteristics of overlaying strata failure after the lower coal seam's mining, height equations of caving zone and fractured zone are given in this paper, and the feasibility of ascending mining was compartmentalized concretely according to the spatiotemporal relationship. Research methods and conclusions of this paper have certain referential significance for the study of ascending mining, mining under water, mining under building, mining under railway and stress-relief mining. | Liang Shun Li Xuehua Mao Yanxin Li Chengjun | 2013 | International Journal of Mining Science and Technology2013，23，2： | 4 |
| 15 | Moment tensor analysis of transversely isotropic shale based on the discrete element method显示文摘In this study,the moment tensor of transversely isotropic shale was analyzed using a discrete element method-acoustic emission model(DEM-AE model).Firstly,the failure modes of the shale obtained from the acoustic emission(AE) events and physical experiments were compared.Secondly,the relationships between AE events and seismic magnitudes,and AE events and the resulting cracks were analyzed.Finally,a moment tensor T-k chart describing the seismic source was introduced to demonstrate the differences in the transversely isotropic shale.The results showed that,for different anisotropy angles,a linear logarithmic relationship existed between the cumulative AE events and the seismic magnitude in the concentration area of the AE events.A normal distribution was observed for the number of AE events as the seismic magnitude changed from small to large.The moment tensor T-k chart indicated that the number and proportion of linear tension cracks in the shale were highest.When θ = 30°,the peak seismic magnitude was at a minimum.The average seismic magnitude in the concentration area of the AE events was also relatively small.Points close to the U=-1/3V line and the number of cracks included in a single AE event were at a minimum,and the corresponding peak stress also reached its lowest level.In contrast,when θ=90°,all related parameters were contrary to the above θ = 30° case.The DEM-AE model and the moment tensor T-k chart are suitable for analyzing the distribution of shale cracks appearing during the loading process.This study can provide constructive references for future research on the fracturing treatment of shale. | Chong Zhaohui Li Xuehua Hou Peng Chen Xiangyu Wu Yuechao | 2017 | International Journal of Mining Science and Technology2017，27，3： | 3 |
| 16 | Development and assessment of quantitative structure-activity relationship models for bioconcentration factors of organic pollutants显示文摘Bioconcentration factors (BCFs) are of great importance for ecological risk assessment of organic chemicals. In this study, a quantitative structure-activity relationship (QSAR) model for fish BCFs of 8 groups of compounds was developed employing partial least squares (PLS) regression, based on linear solvation energy relationship (LSER) theory and theoretical molecular structural descriptors. The guidelines for development and validation of QSAR models proposed by the Organization for Economic Cooperation and Development (OECD) were followed. The model results show that the main factors governing logBCF are Connolly molecular area (CMA), average molecular polarizability (α) and molecular weight (MW). Thus molecular size plays a critical role in affecting the bioconcentration of organic pollutants in fish. For the established model, the multiple correlation coefficient square (RY2) = 0.868, the root mean square error (RMSE) = 0.553 log units, and the leave-many-out cross-validated Q2CUM = 0.860, indicating its good goodness-of-fit and robustness. The model predictivity was evaluated by external validation, with the external explained variance (QE2XT) = 0.755 and RMSE = 0.647 log units. Moreover, the applicability domain of the developed model was assessed and visualized by the Williams plot. The developed QSAR model can be used to predict fish logBCF for organic chemicals within the application domain. | QIN Hong CHEN JingWen WANG Ying WANG Bin LI XueHua LI Fei WANG YaNan | 2009 | Chinese Science Bulletin2009，54，4： | 3 |
| 17 | Comparison of seed germination of four Artemisia species (Asteraceae) in northeastern Inner Mongolia,China显示文摘Two psammophile-dominated Artemisia semi-shrubs (A.wudanica and A.halodendron) and two annual Artemisia forbs (A.sieversiana and A.scoparia) bear significant ecological functions in Horqin Sandy Land,but systematical information on their achenes' germination is very limited.A set of studies were conducted to evaluate seed germination responses to storage periods and methods,different temperatures,lights conditions and sand burial depths,in order to determine inter-specific germination variation in the same genus and to explain how the species adapt to its microhabitat.Fresh achenes of A.wudanica,A.halodendron and A.sieversiana showed high germination capacities,but those of A.scoparia had obvious innate dormancy,which could be broken by chilling and dry storage,especially long-term dry storage.Achene germination of the two semi-shrubs preferred lower temperature fluctuation (10 to 22oC) and was not sensitive to light.But the two annuals preferred higher temperature fluctuation (34 to 22oC) and strong light for their achene germination.These four Artemisia species showed similar responses to sand burial,i.e.soil surface was most favorable for seedling emergence,and the deeper the sand burial,the fewer the seedling emergence.For the two semi-shrubs,their microhabitats are sand dunes with high temperature and intense light,which are not favorable for germination and seedling survival.Only rainfall contributes to temporary decrease of temperature and then triggers germination.We deduced that germination is not the main but a supplementary reproductive mode for the two semi-shrubs in sand dunes.For the two annuals,achene germination is the only reproductive mode,but different responses have been developed for microhabitat adaptation.For A.sieversiana,high germination capacities in wide temperature ranges and all light conditions could improve its competition and advancement in the wettest microhabitats.For A.scoparia,obvious innate dormancy of fresh achenes and germination inhabitation under unfavorable conditions are important adaptation to environmental disturbances. | XueHua LI DeMing JIANG Alamusa QuanLai ZHOU Toshio OSHIDA | 2012 | Journal of Arid Land2012，4，1： | 3 |
| 18 | The return and loss of litter phosphorus in different types of sand dunes in Horqin Sandy Land,northeastern China显示文摘Litter phosphorus(P) return is important to maintain the P cycle and balance in the sandy land of arid areas.In this study,we determined the loss and return of litter P in sand dune areas and elucidated their relationship.We investigated litter production and litter P amount,and simulated leaf litter moving dynamics to understand the relationships between the loss of litter P and the total litter P,and between the return of litter P and the total litter P in active(AD),semi-stabilized(SSD) and stabilized(SD) dunes in Inner Mongolia,northeastern China.The vegetation litter P was 12.6,94.5,and 201.6 mg P/m2 in AD,SSD,and SD,respectively.A significant movement and loss of leaf litter P with time occurred on the three types of sand dunes.As a result,the loss of P was 7.4,46.9,and 69.8 mg P/m2 and the return of P was 5.5,47.6,and 131.8 mg P/m2 in AD,SSD,and SD,respectively.The relationship between both loss and return of P and total litter P in AD,SSD,and SD was revealed by linear regression.The slope of the regression line indicated the rate of loss or return of litter P.From AD to SD,the loss rate showed a declining slope(0.52,0.32,and 0.17 for AD,SSD,and SD,respectively),and the return rate showed a rising slope(0.48,0.67,and 0.83 for AD,SSD,and SD,respectively).The loss of litter P should be regarded in the local management of vegetation and land in sand dune areas.Improved vegetation restoration measures are necessary to decrease litter P loss to maintain the stability of ecosystems in sand dune areas. | QuanLai ZHOU DeMing JIANG ZhiMin LIU Alamusa XueHua LI YongMing LUO HongMei WANG | 2012 | Journal of Arid Land2012，4，4： | 3 |
| 19 | A new long-side-chain sulfonated poly(2,6-dimethyl-1,4-phenylene oxide)(PPO)/polybenzimidazole(PBI)amphoteric membrane for vanadium redox flow battery显示文摘A new amphoteric membrane was prepared by blending long-side-chain sulfonated poly(2,6-dimethyl-1,4-phenylene oxide)(S-L-PPO)and polybenzimidazole(PBI)for vanadium redox flow battery(VRFB)application.An acid-base pair structure formed between the imidazole of PBI and sulfonic acid of S-L-PPO resulted in lowered swelling ratio.It favors to reduce the vanadium permeation.While,the increased sulfonic acid concentration ensured that proton conductivity was still at a high level.As a result,a better balance between the vanadium ion permeation(6.1×10^-9 cm^2·s^-1)and proton conductivity(50.8 m S·cm^-1)in the S-L-PPO/PBI-10%membrane was achieved.The VRFB performance with S-L-PPO/PBI-10%membrane exhibited an EE of 82.7%,which was higher than those of pristine S-L-PPO(81.8%)and Nafion 212(78.0%)at 120 m A·cm^-2.In addition,the S-LPPO/PBI-10%membrane had a much longer self-discharge duration time(142 h)than that of Nafion 212(23 h). | Bowen Jiang Lei Hu Xiaoming Yan Jiahui Sun Li Gao Yan Dai Xuehua Ruan Gaohong He | 2020 | Chinese Journal of Chemical Engineering2020，28，7： | 3 |
| 20 | The role of personality,social economic and prevention strategy effects on health-related quality of life among people living with HIV/AIDS显示文摘Background::HIV/AIDS has transformed into a chronic controllable but not yet curable infectious disease as other chronic diseases to some extent.The additional of so called fourth 90%that included the improved health-related quality of life(HRQoL)for people living with HIV(PLWHIV)required solutions beyond antiretroviral therapy and viral load suppression.This study will explore the role of personality,social economic and prevention strategy effection on HRQoL among people living with HIV/AIDS.Methods::A cross-sectional study was conducted among PLWHIV aged more than 16 years old in the 10 municipalities in Yunnan Province,China from October 2019 to May 2020,enrolling total 1997 participants.Individual-level HRQoL data were measured by 12-item Short Form Health Survey(SF-12)and EuroQol Five Dimensions Questionnaire(EQ-5D-5L).We assembled municipal-level data about social economic from Yunnan Statistical Yearbook in 2020 and strategy practice information from the self-evaluation system.We used the principal component analysis to build the social economic and strategy effect on each area respectively and one-way ANOVA was used to perform univariate analysis to identify the predictors with significant differences.Finally we used multi-level model(MLM)to explore the personality,social economic and strategy effects in health-related quality of life among PLWHIV.Results::The global score for quality of life measured using EQ-5D-5L had an estimated mean score(standard deviation,SD)of 0.901±0.146.The HRQoL score measured using PCS-12 had an estimated mean score(SD)of 46.62±8.55.The mean MCS-12 score(SD)was estimated to be 47.80±9.71.The area-level predictors explained a proportion of 13.6-17.2%for the between-area variation of the HRQoL scores,regardless of the total HRQoL,physical component and mental component.The impacts of stigma(P<0.01),social support(P<0.001),anxiety(P<0.001),depression(P<0.05)and social economic status(P<0.05)on HRQoL at the individual-level were significantly different.The plots visualized the impact of individual-level factors on a respondent’s HRQoL was modified by the area-level characteristics.Conclusions::The study identified the possible strategy determinant of individual HRQoL of PLWHIV and also the area effect on HRQoL.Stigma,social support,anxiety,depression and social economic status were the individual-level determinants on HRQoL.These could be a valuable resource for evaluating the overall health of the areas and help improve local decision making. | Xiaowen Wang Hongbing Luo Enlong Yao RenhaiTang Wenbin Dong Fuyong Liu Jun Liang Huilan Li Minyang Xiao Zuyang Zhang Jin Niu Lijun Song Liru Fu Xuehua Li Shicong Qian Qing Guo Zhizhong Song | 2021 | Infectious Diseases of Poverty2021，10，4： | 3 |
