| 1 | A review of cadmium sorption mechanisms on soil mineral surfaces revealed from synchrotron-based X-ray absorption fine structure spectroscopy:Implications for soil remediation显示文摘The sorption of cadmium(Cd) is one of the most important chemical processes in soil, affecting its fate and mobility in both soil and water and ultimately controlling its bioavailability. In order to fundamentally understand the sorption/desorption of Cd in soil systems, X-ray absorption fine structure spectroscopy(XAFS) has been applied in numerous studies to provide molecular-level information that can be used to characterize the surface adsorption and precipitation reactions that Cd can undergo. This information greatly improves our current knowledge of the possible chemical reactions of Cd in soil. This paper critically reviews the mechanisms of Cd sorption/desorption at the mineral-water interface based on XAFS studies performed over the past twenty years. An introduction to the basic concepts of sorption processes is provided, followed by a detailed interpretation of XAFS theory and experimental data collection and processing,ending finally with a discussion of the atomic/molecular-scale Cd sorption mechanisms that occur at the soil mineral-water interface. Particular emphasis is placed on literature that discusses Cd adsorption and speciation when associated with iron, manganese, and aluminum oxides and aluminosilicate minerals.Multiple sorption mechanisms by which Cd is sorbed by these minerals have been found, spanning from outer-sphere to inner-sphere to surface precipitation,depending on mineral type, surface loading, and pH. In addition, the application of complementary techniques(e.g.,113 Cd nuclear magnetic resonance(NMR) and molecular dynamics simulation) for probing Cd sorption mechanisms is discussed. This review can help to develop appropriate strategies for the environmental remediation of Cd-contaminated soils. | Xinxin MO Matthew G.SIEBECKER Wenxian GOU Ling LI Wei LI | 2021 | Pedosphere2021，31，1： | 5 |

| 3 | Roles of Tet2 in meiosis, fertility and reproductive aging显示文摘Dear Editor,Ten-eleven translocation(Tet)enzymes play important roles in DNA demethylation involved in various biological processes including stem cell pluripotency and differentiation,and tumorigenesis(Dawlaty et al.,2013;Wu and Zhang,2017).Tet2 deficiency or mutation leads to severe hematopoietic defects or myeloid malignancies in mice(Delhommeau et al.,2009;Ko et al.,2010;Moran-Crusio et al.,2011).Restoration of TET2 blocks aberrant self-renewal and leukemia progression in patients possessing TET2 mutations(Cimmino et al.,2017). | Huasong Wang Linlin Liu Mo Gou Guian Huang Chenglei Tian Jiao Yang Haiying Wang Qin Xu Guo_Liang Xu Lin Liu | 2021 | Protein & Cell2021，12，7： | 0 |

| 5 | Correlation between Combined Urinary Metal Exposure and Grip Strength under Three Statistical Models:A Cross-sectional Study in Rural Guangxi显示文摘Objective This study aimed to investigate the potential relationship between urinary metals copper(Cu),arsenic(As),strontium(Sr),barium(Ba),iron(Fe),lead(Pb)and manganese(Mn)and grip strength.Methods We used linear regression models,quantile g-computation and Bayesian kernel machine regression(BKMR)to assess the relationship between metals and grip strength.Results In the multimetal linear regression,Cu(β=−2.119),As(β=−1.318),Sr(β=−2.480),Ba(β=0.781),Fe(β=1.130)and Mn(β=−0.404)were significantly correlated with grip strength(P<0.05).The results of the quantile g-computation showed that the risk of occurrence of grip strength reduction was−1.007(95%confidence interval:−1.362,−0.652;P<0.001)when each quartile of the mixture of the seven metals was increased.Bayesian kernel function regression model analysis showed that mixtures of the seven metals had a negative overall effect on grip strength,with Cu,As and Sr being negatively associated with grip strength levels.In the total population,potential interactions were observed between As and Mn and between Cu and Mn(P_(interactions) of 0.003 and 0.018,respectively).Conclusion In summary,this study suggests that combined exposure to metal mixtures is negatively associated with grip strength.Cu,Sr and As were negatively correlated with grip strength levels,and there were potential interactions between As and Mn and between Cu and Mn. | LIANG Yu Jian RONG Jia Hui WANG Xue Xiu CAI Jian Sheng QIN Li Dong LIU Qiu Mei TANG Xu MO Xiao Ting WEI Yan Fei LIN Yin Xia HUANG Shen Xiang LUO Ting Yu GOU Ruo Yu CAO Jie Jing HUANG Chu Wu LU Yu Fu QIN Jian ZHANG Zhi Yong | 2024 | Biomedical and Environmental Sciences2024，37，1： | 0 |
| 6 | RCT Meta-analysis on Buyang Huanwu Decoction Combined with Acupuncture and Buyang Huanwu Decoction Alone in the Treatment of Apoplectic Hemiplegia显示文摘[Objectives] To evaluate the efficacy and safety of two different treatment regimens( Buyang Huanwu Decoction combined with acupuncture and Buyang Huanwu Decoction alone) in the treatment of apoplectic hemiplegia. [Methods]Electronic databases: China Knowledge Infrastructure( CNKI),Wanfang database( Wan Fang Data),VIP database( VIP),China Biomedical Literature Database( CBM),MEDLINE,The Cochrane Library,Pubmed,Chinese Journal of Integrative Medicine,and Journal of Traditional Chinese Medicine were searched. The published randomized controlled trials( RCT) of Buyang Huanwu Decoction combined with acupuncture and Buyang Huanwu Decoction alone in the treatment of apoplectic hemiplegia were screened. The Jadad scale was used to evaluate the methodological quality of the included literature. The data was extracted and the meta-analysis was carried out with reference to the Systematic Evaluation,Meta-analysis Design and Implementation Method. [Results]A total of 8 articles were included,a total of 765 patients,and there were 8 articles with Jadad scores lower than 4 points. Meta-analysis results indicate that The experimental group of Buyang Huanwu Decoction combined with acupuncture treatment improved the comprehensive clinical efficacy OR = 3. 89,95% CI[2. 58,5. 86]( P < 0. 000 01),BI score SMD = 2. 35,95% CI[2. 04,2. 66]( P <0. 000 01) was better than the control group. [Conclusions]The treatment regimen of Buyang Huanwu Decoction combined with acupuncture can improve the daily activities of patients with apoplectic hemiplegia and improve the clinical efficacy. It is better than the treatment regimen of Buyang Huanwu Decoction alone. | Yao GOU Jingui WU Xueni MO Luxing QIN | 2019 | Medicinal Plant2019，10，3： | 0 |
