| 1 | 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 |
| 2 | A Hu sheep genome with the first ovine Y chromosome reveal introgression history after sheep domestication显示文摘The Y chromosome plays key roles in male fertility and reflects the evolutionary history of paternal lineages.Here,we present a de novo genome assembly of the Hu sheep with the first draft assembly of ovine Y chromosome(o MSY),using nanopore sequencing and Hi-C technologies.The o MSY that we generated spans 10.6 Mb from which 775 Y-SNPs were identified by applying a large panel of whole genome sequences from worldwide sheep and wild Iranian mouflons.Three major paternal lineages(HY1a,HY1b and HY2)were defined across domestic sheep,of which HY2 was newly detected.Surprisingly,HY2 forms a monophyletic clade with the Iranian mouflons and is highly divergent from both HY1a and HY1b.Demographic analysis of Y chromosomes,mitochondrial and nuclear genomes confirmed that HY2 and the maternal counterpart of lineage C represented a distinct wild mouflon population in Iran that diverge from the direct ancestor of domestic sheep,the wild mouflons in Southeastern Anatolia.Our results suggest that wild Iranian mouflons had introgressed into domestic sheep and thereby introduced this Iranian mouflon specific lineage carrying HY2 to both East Asian and Africa sheep populations. | Ran Li Peng Yang Ming Li Wenwen Fang Xiangpeng Yue Hojjat Asadollahpour Nanaei Shangquan Gan Duo Du Yudong Cai Xuelei Dai Qimeng Yang Chunna Cao Weidong Deng Sangang He Wenrong Li Runlin Ma Mingjun Liu Yu Jiang | 2021 | Science China(Life Sciences)2021，64，7： | 1 |
| 3 | Estimation of Lightning-Generated NO_(x) in the Mainland of China Based on Cloud-to-Ground Lightning Location Data显示文摘Lightning-generated nitrogen oxides(LNO_(x))have a major influence on the atmosphere and global climate change.Therefore,it is of great importance to obtain a more accurate estimation of LNO_(x).The aim of this study is to provide a reference for the accurate estimation of the total LNO_(x) in the mainland of China based on cloud-to-ground lightning(CG)location data from 2014 to 2018.The energy of each CG flash was based on the number of return strokes per CG flash,the peak current of each return stroke,and the assumed CG breakdown voltage.The energy of intracloud lightning(IC)was based on the estimated frequencies of IC and the assumed energy of each IC flash.Combining the energy of lightning and the number of nitric oxide(NO)molecules produced by unit energy(ρno),the total LNO_(x) production in the mainland of China was determined.The LNO_(x) in the mainland of China estimated in this study is in the range(0.157-0.321)×10^(9) kg per year[Tg(N)yr-1],which is on the high end of other scholars’works.Negative cloud-to-ground lightning(NCG)flashes produce the most moles of NO_(x),while positive cloud-to-ground lightning(PCG)flashes produce the least total moles of NO_(x).The breakdown voltage of PCG is greater than that of IC or NCG,while the latter has a greater output of LNO_(x). | Qi LI Fengxia GUO Xiaoyu JU Ze LIU Mingjun GAN Kun ZHANG Binbin CAI | 2023 | Advances in Atmospheric Sciences2023，40，1： | 0 |
