1Prevalence of Autism Spectrum Disorder in China:A Nationwide Multi-center Population-based Study Among Children Aged 6 to 12 Years显示文摘This study aimed to obtain the first national estimate of the prevalence of autism spectrum disorder(ASD) in Chinese children.We targeted the population of 6 to 12-year-old children for this prevalence study by multistage convenient cluster sampling.The Modified Chinese Autism Spectrum Rating Scale was used for the screening process.Of the target population of 142,086 children,88.5%(n=125,806) participated in the study.A total of 363 children were confirmed as having ASD.The observed ASD prevalence rate was 0.29%(95% CI:0.26%-0.32%) for the overall population.After adjustment for response rates,the estimated number of ASD cases was867 in the target population sample,thereby achieving an estimated prevalence of 0.70%(95% CI:0.64%-0.74%).The prevalence was significantly higher in boys than in girls(0.95%;95% CI:0.87%-1.02% versus 0.30%;95%CI:0.26%-0.34%;P <0.001).Of the 363 confirmed ASD cases,43.3% were newly diagnosed,and most of those(90.4%) were attending regular schools,and 68.8% of the children with ASD had at least one neuropsychiatric comorbidity.Our findings provide reliable data on the estimated ASD prevalence and comorbidities in Chinese children.Hao Zhou Xiu Xu Weili Yan Xiaobing Zou Lijie Wu Xuerong Luo Tingyu Li Yi Huang Hongyan Guan Xiang Chen Meng Mao Kun Xia Lan Zhang Erzhen Li Xiaoling Ge Lili Zhang Chunpei Li Xudong Zhang Yuanfeng Zhou Ding Ding Andy Shih Eric Fombonne Yi Zheng Jisheng Han Zhongsheng Sun Yong-hui Jiang Yi Wang LATENT-NHC Study Team 2020Neuroscience Bulletin2020,36,9:158

3Androgen receptor: structure, role in prostate cancer and drug discovery显示文摘Androgens and androgen receptors (AR) play a pivotal role in expression of the male phenotype. Several diseases, such as androgen insensitivity syndrome (AIS) and prostate cancer, are associated with alterations in AR functions. Indeed, androgen blockade by drugs that prevent the production of androgens and/or block the action of the AR inhibits prostate cancer growth. However, resistance to these drugs often occurs after 2-3 years as the patients develop castration-resistant prostate cancer (CRPC). In CRPC, a functional AR remains a key regulator. Early studies focused on the functional domains of the AR and its crucial role in the pathology. The elucidation of the structures of the AR DNA binding domain (DBD) and ligand binding domain (LBD) provides a new framework for understanding the functions of this receptor and leads to the development of rational drug design for the treatment of prostate cancer. An overview of androgen receptor structure and activity, its actions in prostate cancer, and how structural information and high-throughput screening have been or can be used for drug discovery are provided herein.MH Eileen TAN Jun LI H Eric XU Karsten MELCHER Eu-leong YONG 2015Acta Pharmacologica Sinica2015,36,1:39

7Reflective chiral meta-holography: multiplexing holograms for circularly polarized waves显示文摘By allowing almost arbitrary distributions of amplitude and phase of electromagnetic waves to be generated by a layer of sub-wavelength-size unit cells,metasurfaces have given rise to the field of meta-holography.However,holography with circularly polarized waves remains complicated as the achiral building blocks of existing meta-holograms inevitably contribute to holographic images generated by both left-handed and right-handed waves.Here we demonstrate how planar chirality enables the fully independent realization of high-efficiency meta-holograms for one circular polarization or the other.Such circular-polarization-selective meta-holograms are based on chiral building blocks that reflect either left-handed or right-handed circularly polarized waves with an orientation-dependent phase.Using terahertz waves,we experimentally demonstrate that this allows the straightforward design of reflective phase meta-holograms,where the use of alternating structures of opposite handedness yields independent holographic images for circularly polarized waves of opposite handedness with negligible polarization cross-talk.Qiu Wang Eric Plum Quanlong Yang Xueqian Zhang Quan Xu Yuehong Xu Jiaguang Han Weili Zhang 2018Light(Science & Applications)2018,7,1:15
8Receiver function analysis for seismic structure of the crust and uppermost mantle in the Liupanshan area, China显示文摘A portable broadband seismic array was deployed from the northeast Tibetan Plateau to the southwest Ordos block, China. The seismic structure of the crust and uppermost mantle of the Liupanshan area is obtained using receiver function analysis of teleseismic body waves. The crustal thickness and Poisson's ratios are estimated by stacking the weighted amplitudes of receiver functions. Our results reveal complex seismic phases in the Liupanshan area, implying intense deformation at the boundary between the Tibetan Plateau and the Ordos block. The average crustal thickness is 51.5 km in the northeast Tibetan Plateau, 53.5 km in the Liupan Mountain and 50 km in the southwest Ordos block, resulting in a concave Moho beneath the Liupan Mountain. The Poisson's ratio of the Liupanshan area varies between 0.27-0.29, higher than the value of 0.25-0.26 to the east and west of the Liupan Mountain, suggesting partial melting in the lower crust. The variance in Poisson's ratio across the Liupan Mountain indicates notable changes in the crustal composition and mechanical properties, which may be formed by the northeastward flow of the Tibetan lower crust during the India-Eurasia collision.TONG WeiWei WANG LiangShu MI Ning XU MingJie LI Hua YU DaYong LI Cheng LIU ShaoWen LIU Mian Eric SanDvol 2007Science China Earth Sciences2007,50,z2:9
9Oncogenic AURKA-enhanced N6-methyladenosine modification increases DROSHA mRNA stability to transactivate STC1 in breast cancer stem-like cells显示文摘RNase III DROSHA is upregulated in multiple cancers and contributes to tumor progression by hitherto unclear mechanisms.Here,we demonstrate that DROSHA interacts withβ-Catenin to transactivate STC1 in an RNA cleavage-independent manner,contributing to breast cancer stem-like cell(BCSC)properties.DROSHA mRNA stability is enhanced by N6-methyladenosine(m^(6)A)modification which is activated by AURKA in BCSCs.AURKA stabilizes METTL14 by inhibiting its ubiquitylation and degradation to promote DROSHA mRNA methylation.Moreover,binding of AURKA to DROSHA transcript further strengthens the binding of the m^(6)A reader IGF2BP2 to stabilize m^(6)A-modified DROSHA.In addition,wild-type DROSHA,but not an m^(6)A methylation-deficient mutant,enhances BCSC stemness maintenance,while inhibition of DROSHA m^(6)A modification attenuates BCSC traits.Our study unveils the AURKA-induced oncogenic m^(6)A modification as a key regulator of DROSHA in breast cancer and identifies a novel DROSHA transcriptional function in promoting the BCSC phenotype.Fei Peng Jie Xu Bai Cui Qilan Liang Sai Zeng Bin He Hong Zou Manman Li Huan Zhao Yuting Meng Jin Chen Bing Liu Shasha Lv Peng Chu Fan An Zifeng Wang Junxiu Huang Yajing Zhan Yuwei Liao Jinxin Lu Lingzhi Xu Jin Zhang Zhaolin Su Zhiguang Li Fangjun Wang Eric W-FLam Quentin Liu 2021Cell Research2021,31,3:9

11Modifying the Autism Spectrum Rating Scale(6–18 years)to a Chinese Context:An Exploratory Factor Analysis显示文摘The purpose of this study was to explore the psychometric properties of the Chinese version of the autism spectrum rating scale(ASRS). We recruited 1,625community-based children and 211 autism spectrum disorder(ASD) cases from 4 sites, and the parents of all participants completed the Chinese version of the ASRS. A robust weighted least squares means and variance adjusted estimator was used for exploratory factor analysis. The3-factor structure included 59 items suitable for the current sample. The item reliability for the modi?ed Chinese version of the ASRS(MC-ASRS) was excellent. Moreover,with 60 as the cut-off point, receiver operating characteristic analysis showed that the MC-ASRS had excellent discriminate validity, comparable to that of the unmodi?ed Chinese version(UC-ASRS), with area under the curve values of 0.952(95% CI: 0.936–0.967) and 0.948(95% CI:0.930–0.965), respectively. Meanwhile, the con?rm factor analysis revealed that MC-ASRS had a better construct validity than UC-ASRS based on the above factor solution in another children sample. In conclusion, the MC-ASRS shows better ef?cacy in epidemiological screening for ASD in Chinese children.Hao Zhou Lili Zhang Xuerong Luo Lijie Wu Xiaobing Zou Kun Xia Yimin Wang Xiu Xu Xiaoling Ge Yong-Hui Jiang Eric Fombonne Weili Yan Yi Wang 2017Neuroscience Bulletin2017,33,2:8

14Chinese Norms for the Autism Spectrum Rating Scale显示文摘This study aimed to establish norms for the modi?ed Chinese version of the Autism Spectrum Rating Scale(ASRS). Participants were recruited from Shanghai,Harbin, Guangzhou, and Changsha, China, and their parents and teachers were invited to complete the Chinese Parent version and the Teacher version of the ASRS. In both versions, boys had signi?cantly higher sub-scale scores and total score(T-score) by 1–3 and 4–5 points respectively, than girls(both P \ 0.001). Age had weak correlations with some sub-scores and the T-score(r ranged from-0.1859 to 0.0738), and some reached signi?cance(P \ 0.03). The correlations appeared stronger and were more common in females. The T-score based on Chinese norms ideally correlated with the score based on the United States norms in boys and girls for both versions.Norms for the Chinese version of the ASRS for children aged 6–12 years are proposed and may be helpful for screening individuals with autism spectrum disorders from the general population of children.Hao Zhou Lili Zhang Xiaobing Zou Xuerong Luo Kun Xia Lijie Wu Yimin Wang Xiu Xu Xiaoling Ge Yong-Hui Jiang Eric Fombonne Weili Yan Yi Wang 2017Neuroscience Bulletin2017,33,2:5
15Assessing the Accuracy of the Modified Chinese Autism Spectrum Rating Scale and Social Responsiveness Scale for Screening Autism Spectrum Disorder in Chinese Children显示文摘The reported prevalence of autism spectrum disorder(ASD) has been increasing rapidly in many parts of the world. However, data on its prevalence in China are largely missing. Here, we assessed the suitability of the modi?ed Chinese version of a newly-developed ASD screening tool, the Modi?ed Chinese Autism Spectrum Rating Scales(MC-ASRS) in screening for ASD in Chi nese children aged 6–12 years, through comparison with the Social Responsiveness Scale(SRS) that has been widely used for ASD screening. We recruited the par ents/caregivers of 1588 typically-developing children and190 children with ASD aged 6–12 years to complete the MC-ASRS and SRS, and evaluated the validity of both scales in discriminating children with ASD from those developing typically. The results showed that MC-ASRSperformed as well as SRS in sensitivity, speci?city, and area-under-the-curve(both [0.95) in receiver operating characteristic analysis, with a fair false-negative rate.These results suggest that MC-ASRS is a promising tool for screening for children with ASD in the general Chinese population.Bingrui Zhou Hao Zhou Lijie Wu Xiaobing Zou Xuerong Luo Eric Fombonne Yi Wang Weili Yan Xiu Xu 2017Neuroscience Bulletin2017,33,2:5
16Mesenchymal stem cell treatment improves outcome of COVID-19 patients via multiple immunomodulatory mechanisms显示文摘The infusion of coronavirus disease 2019(COVID-19)patients with mesenchymal stem cells(MSCs)potentially improves clinical symptoms,but the underlying mechanism remains unclear.We conducted a randomized,single-blind,placebo-controlled(29 patients/group)phase II clinical trial to validate previous findings and explore the potential mechanisms.Patients treated with umbilical cord-derived MSCs exhibited a shorter hospital stay(P=0.0198)and less time required for symptoms remission(P=0.0194)than those who received placebo.Based on chest images,both severe and critical patients treated with MSCs showed improvement by day 7(P=0.0099)and day 21(P=0.0084).MSC-treated patients had fewer adverse events.MSC infusion reduced the levels of C-reactive protein,proinflammatory cytokines,and neutrophil extracellular traps(NETs)and promoted the maintenance of SARS-CoV-2-specific antibodies.To explore how MSCs modulate the immune system,we employed single-cell RNA sequencing analysis on peripheral blood.Our analysis identified a novel subpopulation of VNN2+hematopoietic stem/progenitorlike(HSPC-like)cells expressing CSF3R and PTPRE that were mobilized following MSC infusion.Genes encoding chemotaxis factors—CX3CR1 and L-selectin—were upregulated in various immune cells.MSC treatment also regulated B cell subsets and increased the expression of costimulatory CD28 in T cells in vivo and in vitro.In addition,an in vivo mouse study confirmed that MSCs suppressed NET release and reduced venous thrombosis by upregulating kindlin-3 signaling.Together,our results underscore the role of MSCs in improving COVID-19 patient outcomes via maintenance of immune homeostasis.Rongjia Zhu Tingdong Yan Yingmei Feng Yan Liu Hongcui Cao Gongxin Peng Yanlei Yang Zhen Xu Jingqi Liu Wei Hou Xiaoyue Wang Zhe Li Luchan Deng Shihua Wang Jing Li Qin Han Hongling Li Guangliang Shan Yinghao Cao Xingyan An Jianshe Yan Zhonghui Zhang Huafei Li Xuebin Qu Jiaqi Zhu Shumin Zhou Jiao Wang Fengchun Zhang Jinming Gao Ronghua Jin Dayong Xu Yan-Qing Ma Tao Huang Shuang Peng Zhi Zheng Ilia Stambler Eric Gilson Lee Wei Lim Alexey Moskalev Antonio Cano Sasanka Chakrabarti Brun Ulfhake Huanxing Su Haoying Xu Sihuan Xu Feng Wei Holly MBrown-Borg Kyung-Jin Min Georgina Ellison-Hughes Calogero Caruso Kunlin Jin Robert Chunhua Zhao 2021Cell Research2021,31,12:5
