| 1 | First dark matter search results from the PandaX-Ⅰ experiment显示文摘We report on the first dark-matter(DM)search results from PandaX-I,a low threshold dual-phase xenon experiment operating at the China JinPing Underground Laboratory.In the 37-kg liquid xenon target with 17.4 live-days of exposure,no DM particle candidate event was found.This result sets a stringent limit for low-mass DM particles and disfavors the interpretation of previously-reported positive experimental results.The minimum upper limit,3.7×10-44cm2,for the spin-independent isoscalar DM-particle-nucleon scattering cross section is obtained at a DM-particle mass of 49 GeV/c2at 90%confidence level. | XIAO MengJiao XIAO Xiang ZHAO Li CAO XiGuang CHEN Xun CHEN YunHua CUI XiangYi FANG DeQing FU ChangBo GIBONI Karl L.

| 2 | Metal Sealing Performance of Subsea X-tree Wellhead Connector Sealer显示文摘The metal sealing performance of subsea X-tree wellhead connectors is crucial for the safety and reliability of subsea X-trees. In order to establish the theoretical relation between metal sealing ring's contact stress and its structural parameters and working pressure, a mechanical analysis method for double-cone sealing of high pressure vessels is applied in analyzing the metal sealing ring under the condition of preload and operation. As a result, the formula of the unit sealing load for the metal sealing ring under operation with residual preload is shown in this paper, which ensures that the metal sealing ring has an excellent sealing effect and can prevent the metal sealing ring from yielding. Besides, while analyzing the sealing process of the metal sealing ring, the change rule of contact stress and working pressure is concluded here, putting forward that the structural parameters of the metal sealing ring are the major factors affecting the change rule. Finally, the analytical solution through theoretical analysis is compared with the simulation result through finite element analysis in a force feedback experiment, and both are consistent with each other, which fully verifies for the design and calculation theory on metal sealing ring's contact stress and its structural parameters and working pressure deduced in this paper. The proposed research will be treated as an applicable theory guiding the design of metal seal for subsea X-tree wellhead connectors. | ZHAO Honglin CHEN Rui LUO Xiaolan DUAN Menglan LU Yinghui FU Guowei TIAN Hongping YE Daohui | 2015 | Chinese Journal of Mechanical Engineering2015，28，3： | 9 |

| 4 | Growth and wood properties of a 38-year-old Populus simonii 3 P.nigra plantation established with different densities in semi-arid areas of northeastern China显示文摘To characterize the effects of plantation densities on the growth characteristics(diameter at breast level,tree height and volume)and the common wood properties,38-year-old Populus simonii 9 P.nigra clones planted with four levels of spacing(2 m 92 m,3 m 93 m,4 m 94 m,and 5 m 95 m)in a semi-arid area in northeastern China were examined.The results of ANOVA showed significant differences(P\0.01)for all the investigated growth traits and wood properties under different plantation densities,except for the chemical composition of wood.The repeatability and phenotypic variations of all the traits varied from 0.34 to 0.99 and from 13.45 to 59.65%,respectively.Except for wood density,which was significantly negatively correlated with the growth traits,a positive correlation was observed between the growth traits and all the other wood mechanical properties.However,most of the correlations between the growth traits and the chemical composition of the wood were not significant.The path analysis for the wood mechanical characteristics and the growth in the prediction of volume were significant and ranged from 0.18 to 0.72 for wood density and diameter at breast height,respectively,while those for the chemical composition of wood ranged from 0.001 to 0.336,which showed a low impact on the volume.The highest stand volume(610 m3)per hectare was observed with the 2 m 92 m spacing,which consequently provided a high total price and income,while a high individual volume growth per tree was observed with the 5 m 95 m spacing.The results suggested that for the poplar trees younger than 40 years in a semi-arid area in China,2 m 92 m spacing is suitable for obtaining a high volume per hectare,while 5 m 95 m spacing is best for obtaining a high individual volume per tree. | Ammar Khalil Mohamed Ahmed Zhixiang Fu Changjun Ding Luping Jiang Xidong Han Aiguo Yang Yinghui Ma Xiyang Zhao | 2020 | Journal of Forestry Research2020，31，2： | 6 |
| 5 | Genetic contribution of foreign germplasm to elite Chinese soybean (Glycine max) cultivars revealed by SSR markers显示文摘Simple sequence repeats (SSR) marker analysis, combined with pedigree analysis, was car- ried out to trace the genetic constitutes of Suinong 14 and Hefeng 25 in assessing the contribution of for- eign germplasm to those elite cultivars. The overall goal is to accumulate information for further effective utilization of foreign germplasm in Chinese soybean breeding programs. SSR clustering results indicated that the genetic base of elite Chinese soybean culti- vars, including Suinong 14 and Hefeng 25, were broadened and enhanced via introduction of Amsoy from the U.S. and Shishengchangye from Japan. The pedigree analysis showed a very high coefficient of parentage between Shishengchangye and Hefeng 25, between Shishengchangye and Suinong 14, and between Amsoy and Suinong 14. The genetic simi- larity between Suinong 14 and Hefeng 25 was 60.58%. Among 20 linkage groups, more genomic regions were transferred from Hefeng 25 to Suinong 14 in linkage group (LG) I, L and C2 than other LGs. Among the unique alleles of foreign parents, five specific loci in Amsoy were transferred to Suinong 14, and three loci from Shishengchangye to Suinong 14. Some SSR loci were proved to be correlated with phenotypes: two loci for seed size introgressed from Shishengchangye to Suinong 14, and one locus forprotein content from Amsoy to Suinong 14. These results indicate that the two foreign parents might have important contributions in the development of Suinong 14 and Hefeng 25. | QIN Jun CHEN Weiyuan GUAN Rongxia JIANG Chengxi LI Yinghui FU Yashu LIU Zhangxiong ZHANG Mengchen CHANG Ruzhen QIU Lijuan | 2006 | Chinese Science Bulletin2006，51，9： | 4 |

| 7 | Drug target inference by mining transcriptional data using a novel graph convolutional network framework显示文摘A fundamental challenge that arises in biomedicine is the need to characterize compounds in a relevant cellular context in order to reveal potential on-target or offtarget effects.Recently,the fast accumulation of gene transcriptional profiling data provides us an unprecedented opportunity to explore the protein targets of chemical compounds from the perspective of cell transcriptomics and RNA biology.Here,we propose a novel Siamese spectral-based graph convolutional network(SSGCN)model for inferring the protein targets of chemical compounds from gene transcriptional profiles.Although the gene signature of a compound perturbation only provides indirect clues of the interacting targets,and the biological networks under different experiment conditions further complicate the situation,the SSGCN model was successfully trained to learn from known compound-target pairs by uncovering the hidden correlations between compound perturbation profiles and gene knockdown profiles.On a benchmark set and a large time-split validation dataset,the model achieved higher target inference accuracy as compared to previous methods such as Connectivity Map.Further experimental validations of prediction results highlight the practical usefulness of SSGCN in either inferring the interacting targets of compound,or reversely,in finding novel inhibitors of a given target of interest. | Feisheng Zhong Xiaolong Wu Ruirui Yang Xutong Li Dingyan Wang Zunyun Fu Xiaohong Liu XiaoZhe Wan Tianbiao Yang Zisheng Fan Yinghui Zhang Xiaomin Luo Kaixian Chen Sulin Zhang Hualiang Jiang Mingyue Zheng | 2022 | Protein & Cell2022，13，4： | 1 |
| 8 | Burdens Attributable to Intimate Partner Violence in Women Aged 15 Years or Older—China,1990–2019显示文摘Summary What is already known about this topic?Intimate partner violence(IPV)represents a significant global public health concern.What is added by this report?The burden of HIV/AIDS related to IPV demonstrated an upward trend from 1990 to 2019,exhibiting an annual growth of 4.66%in age-standardized death rates(ASDR)and 4.42%in age-standardized disabilityadjusted life years(DALYs)rates.Notably,the age groups 30–34 and 50–54 experienced a higher IPV burden compared to other age groups.What are the implications for public health practice?There is a pressing need for public health policymakers to develop efficacious interventions aimed at bolstering the surveillance and prevention of IPV targeted at women in China. | Leiwen Fu Tian Tian Zhen Lu Bingyi Wang Xinyi Li Weijie Zhang Yanxiao Gao Yinghui Sun Huachun Zou | 2023 | China CDC weekly2023，5，16： | 0 |
| 9 | Cell-cycle length of medial ganglionic eminence progenitors contributes to interneuron fate显示文摘Dear Editor,GABAergic interneurons contribute to cortical function by regulating the balance of activity.Malfunction of inhibitory interneurons has been associated with neuropsychiatric disorders(Hashimoto et al.2003;Marín 2012).The most striking feature of GABAergic interneurons is their diversity of cell types.Although fate-mapping studies have demonstrated the presence of spatially and temporally distinct progenitor domains for interneuron subclasses within the embryonic ventral telencephalon(Butt et al.2005;Inan et al.2012),the mechanisms of interneuron subtype-determination during development remain poorly understood. | Ni Zong Min Wang Yinghui Fu Dan Shen Yong-Chun Yu | 2022 | Protein & Cell2022，13，2： | 0 |
| 10 | Correlation Analysis of Molecularly-Defined Cortical Interneuron Populations with Morpho-Electric Properties in Layer V of Mouse Neocortex显示文摘Cortical interneurons can be categorized into distinct populations based on multiple modalities,including molecular signatures and morpho-electrical(M/E)properties.Recently,many transcriptomic signatures based on single-cell RNA-seq have been identified in cortical interneurons.However,whether different interneuron populations defined by transcriptomic signature expressions correspond to distinct M/E subtypes is still unknown.Here,we applied the Patch-PCR approach to simultaneously obtain the M/E properties and messenger RNA(mRNA)expression of>600 interneurons in layer V of the mouse somatosensory cortex(S1).Subsequently,we identified 11 M/E subtypes,9 neurochemical cell populations(NCs),and 20 transcriptomic cell populations(TCs)in this cortical lamina.Further analysis revealed that cells in many NCs and TCs comprised several M/E types and were difficult to clearly distinguish morpho-electrically.A similar analysis of layer V interneurons of mouse primary visual cortex(V1)and motor cortex(M1)gave results largely comparable to S1.Comparison between S1,V1,and M1 suggested that,compared to V1,S1 interneurons were morpho-electrically more similar to M1.Our study reveals the presence of substantial M/E variations in cortical interneuron populations defined by molecular expression. | Jun-Wei Cao Xiao-Yi Mao Liang Zhu Zhi-Shuo Zhou Shao-Na Jiang Lin-Yun Liu Shu-Qing Zhang Yinghui Fu Wen-Dong Xu Yong-Chun Yu | 2023 | Neuroscience Bulletin2023，39，7： | 0 |
| 11 | Immediate and long-term outcomes after treat-all among people living with HIV in China:an interrupted time series analysis显示文摘Background In 2003,China implemented free antiretroviral therapy(ART)for people living with HIV(PLHIV),establishing an eligibility threshold of CD4<200 cells/μl.Subsequently,the entry criteria were revised in 2012(eligibility threshold:CD4≤350 cells/μl),2014(CD4≤500 cells/μl),and 2016(treat-all).However,the impact of treat-all policy on HIV care and treatment indicators in China is unknown.We aimed to elucidate the immediate and long-term impact of the implementation of treat-all policy in China.Methods Anonymized programmatic data on ART initiation and collection in PLHIV who newly started ART were retrieved between 1 January 2015 and 31 December 2019,from two provincial and municipal Centers for Disease Control and Prevention and ten major infectious disease hospitals specialized in HIV care in China.We used Poisson and quasi-Poisson segmented regression models to estimate the immediate and long-term impact of treat-all on three key indicators:monthly proportion of 30-day ART initiation,mean CD4 counts(cells/μl)at ART initiation,and mean estimated time from infection to diagnosis(year).We built separate models according to gender,age,route of transmission and region.Results Monthly data on ART initiation and collection were available for 75,516 individuals[gender:83.8%males;age:median 39 years,interquartile range(IQR):28-53;region:18.5%Northern China,10.9%Northeastern China,17.5%Southern China,49.2%Southwestern China].In the first month of treat-all,compared with the contemporaneous counterfactual,there was a significant increase in proportion of 30-day ART initiation[+12.6%,incidence rate ratio(IRR)=1.126,95%CI:1.033-1.229;P=0.007]and mean estimated time from infection to diagnosis(+7.0%,IRR=1.070,95%CI:1.021-1.120;P=0.004),while there was no significant change in mean CD4 at ART initiation(IRR=0.990,95%CI:0.956-1.026;P=0.585).By December 2019,the three outcomes were not significantly different from expected levels.In the stratified analysis,compared with the contemporaneous counterfactual,mean CD4 at ART initiation showed significant increases in Northern China(+3.3%,IRR=1.033,95%CI:1.001-1.065;P=0.041)and Northeastern China(+8.0%,IRR=1.080,95%CI:1.003-1.164;P=0.042)in the first month of treat-all;mean estimated time from infection to diagnosis showed significant increases in male(+5.6%,IRR=1.056,95%CI:1.010-1.104;P=0.016),female(+14.8%,IRR=1.148,95%CI:1.062-1.240;P<0.001),aged 26-35(+5.3%,IRR=1.053,95%CI:1.001-1.109;P=0.048)and>50(+7.8%,IRR=1.078,95%CI:1.000-1.161;P=0.046),heterosexual transmission(+12.4%,IRR=1.124,95%CI:1.042-1.213;P=0.002)and Southwestern China(+12.9%,IRR=1.129,95%CI:1.055-1.208;P<0.001)in the first month of treat-all.Conclusions The implementation of treat-all policy in China was associated with a positive effect on HIV care and treatment outcomes.To advance the work of rapid ART,efforts should be made to streamline the testing and ART initiation process,provide comprehensive support services,and address the issue of uneven distribution of medical resources. | Xinsheng Wu Guohui Wu Ping Ma Rugang Wang Linghua Li Yinghui Sun Junjie Xu Yuwei Li Tong Zhang Quanmin Li Yuecheng Yang Lijing Wang Xiaoli Xin Ying Qiao Bingxue Fang Zhen Lu Xinyi Zhou Yuanyi Chen Qi Liu Gengfeng Fu Hongxia Wei Xiaojie Huang Bin Su Hui Wang Huachun Zou | 2023 | Infectious Diseases of Poverty2023，12，4： | 0 |

| 13 | Design of A Novel Wheel-Legged Robot with Rim Shape Changeable Wheels显示文摘The wheel-legged hybrid structure has been utilized by ground mobile platforms in recent years to achieve good mobility on both flat surfaces and rough terrain.However,most of the wheel-legged robots only have one-directional obstacle-crossing ability.During the motion,most of the wheel-legged robots’centroid fluctuates violently,which damages the stability of the load.What’s more,many designs of the obstacle-crossing part and transformation-driving part of this structure are highly coupled,which limits its optimal performance in both aspects.This paper presents a novel wheel-legged robot with a rim-shaped changeable wheel,which has a bi-directional and smooth obstacle-crossing ability.Based on the kinematic model,the geometric parameters of the wheel structure and the design variables of the driving four-bar mechanism are optimized separately.The kinetostatics model of the mobile platform when climbing stairs is established to determine the body length and angular velocity of the driving wheels.A pro-totype is made according to the optimal parameters.Experiments show that the prototype installed with the novel transformable wheels can overcome steps with a height of 1.52 times of its wheel radius with less fluctuation of its centroid and performs good locomotion capabilities in different environments. | Ze Fu Hao Xu Yinghui Li Weizhong Guo | 2023 | Chinese Journal of Mechanical Engineering2023，36，6： | 0 |
| 14 | Effect of New Dayuan powder on methicillin-resistant Staphylococcus aureus biofilms in vitro显示文摘OBJECTIVE:To observe the effects of New Dayuan powder(NDYP)on Methicillin-resistant Staphylococcus aureus(MRSA)biofilms and the embedded bacteria in vitro.METHODS:2,3-Bis-(2-methoxy-4-nitro-5-sulfophenyl)-2 H-tetrazolium-5-carboxanilide(XTT)assays were used to study the effects of NDYP on developing MRSA biofilms:100μL of bacterial culture and100μL drug solution were added to wells of96-well plates.After 24 h of incubation,the plates were washed and XTT-phenazine methyl sulfate(PMS)was added to enable counting of the number of live bacteria in biofilms using a microplate reader.XTT assays were also used to explore the effects of NDYP on mature MRSA biofilms:100μL of bacterial culture were added to wells of 96-well plates.Bacteria were cultured in the plates for 24 h,and then drug solution was added.The plates were cultured for another 24 h,and then XTT-PMS was added to detect the number of live bacteria in the biofilms.Scanning electron microscopy(SEM)was used to observe the effects of NDYP on mature MRSA biofilms:washed and sterilized glass coverslips were added to 24-well plates.Bacterial culture was added.After 24 h of incubation,drug solution was added.After another 24 h of incubation,the samples were observed by SEM.RESULTS:XTT assays showed that the number of live bacteria in both developing and mature MRSA biofilms decreased significantly(P<0.01)after the administration of NDYP.SEM images showed that NDYP could destroy the structure of the bacteria and resulted in uneven thickness of MRSA biofilms.CONCLUSION:In vitro,NDYP has obvious inhibitory effects on the formation of MRSA biofilms and on mature biofilms. | Zhu Li Liu Chang Zuo Xue Fu Zheng Wang Yinghui Wang Yi Qi Wensheng | 2019 | Journal of Traditional Chinese Medicine2019，39，6： | 0 |
| 15 | mvPPT:A Highly Efficient and Sensitive Pathogenicity Prediction Tool for Missense Variants显示文摘Next-generation sequencing technologies both boost the discovery of variants in the human genome and exacerbate the challenges of pathogenic variant identification.In this study,we developed Pathogenicity Prediction Tool for missense variants(mvPPT),a highly sensitive and accurate missense variant classifier based on gradient boosting.mvPPT adopts high-confidence training sets with a wide spectrum of variant profiles,and extracts three categories of features,including scores from existing prediction tools,frequencies(allele frequencies,amino acid frequencies,and genotype frequencies),and genomic context.Compared with established predictors,mvPPT achieves superior performance in all test sets,regardless of data source.In addition,our study also provides guidance for training set and feature selection strategies,as well as reveals highly relevant features,which may further provide biological insights into variant pathogenicity. | Shi-Yuan Tong Ke Fan Zai-Wei Zhou Lin-Yun Liu Shu-Qing Zhang Yinghui Fu Guang-Zhong Wang Ying Zhu Yong-Chun Yu | 2023 | Genomics, Proteomics & Bioinformatics2023，21，2： | 0 |
| 16 | Sexual Risk Behavior and Satisfaction Among Men Who Have Sex With Men Living With Detectable HIV Viral Loads:A Nationwide Online Survey in China显示文摘Little is known about sexual behavior and satisfaction among men who have sex with men(MSM)with detectable HIV viral loads(VL)in China.This study aims to investigate sexual risk behavior and sexual satisfaction among MSM living with HIV in China,as well as poten-tial predictors.This cross-sectional study was conducted in February 2021 using an anonymous online survey based on WeChat.Data were collected on sociodemographics,sexual behavior,HIV clinical information,sexual satisfaction and mental health.Descriptive sta-tistics,logistic regression and multivariable logistic regression were performed.MSM with detectable HIV VL(VL+)or VL not sure were more likely to report inconsistent condom use,even with HIV-negative/unknown-status regular male partners.Having an HIV-positive regular partner and recreational drug use were positively associated with inconsistent condom use during anal sex among MSM with undetectable VL(VL-).Alcohol use before or during sexual activities was positively associated with inconsistent condom use during anal sex among VL+or VL not sure MSM.A total of 58.3%of participants reported being sexually satisfied.MSM living with HIV who were currently employed,had experienced anal sex in the prior 6 months,had VL-HIV status,or had more frequent ejaculation during sex/masturbation were more likely to report sexual satisfaction.The development of targeted education and interventions to minimize sexual risk behavior among MSM living with HIV is in dire need.Treating sexual dysfunction and developing a reasonable antiretroviral therapy regimen to achieve viral suppression can help promote sexual satisfaction in MSM living with HIV. | Leiwen Fu Bingyi Wang Tian Tian Xinyi Zhou Zhen Lu Yinghui Sun Weiran Zheng Yanxiao Gao Yi-Fan Lin Hui Li Huachun Zou | 2023 | Infectious Microbes & Diseases2023，5，3： | 0 |
