| 1 | Generation and characterization of stable pig pregastrulation epiblast stem cell lines显示文摘Pig epiblast-derived pluripotent stem cells are considered to have great potential and broad prospects for human therapeutic model developme nt and livestock breeding.Despite on going attempts since the 1990s,no stably defined pig epiblast-derived stem cell line has bee n established.Here,guided by in sights from a large-scale sin gle-cell tran scriptome an alysis of pig embryos from embryonic day(E)0 to E14,specifically,the tracing of pluripotency changes during epiblast development,we developed an in vitro culture medium for establishing and maintaining stable pluripotent stem cell lines from pig E10 pregastrulation epiblasts(pgEpiSCs).Enabled by chemical inhibition of WNT-related signaling in combination with growth factors in the FGF/ERK,JAK/STAT3,and Activin/Nodal pathways,pgEpiSCs maintain their pluripotency transcriptome features,similar to those of E10 epiblast cells,and normal karyotypes after more than 240 passages and have the potential to differentiate into three germ layers.Strikingly,ultradeep in situ Hi-C analysis revealed functional impacts of chromatin 3D-spatial associations on the transcriptional regulation of pluripote ncy marker genes in pgEpiSCs.I n practice,we con firmed that pgEpiSCs readily tolerate at least three rounds of successive gene editi ng and gene rated cloned gen e-edited live piglets.Our findings deliver on the long-a nticipated promise of pig pluripote nt stem cells and open new avenues for biological research,animal husbandry,and regenerative biomedicine. | Minglei Zhi Jinying Zhang Qianzi Tang Dawei Yu Shuai Gao Dengfeng Gao Pengliang Liu Jianxiong Guo Tang Hai Jie Gao Suying Cao Zimo Zhao Chongyang Li Xiaogang Weng Mengnan He Tianzhi Chen Yingjie Wang Keren Long Deling Jiao Guanglei Li Jiaman Zhang Yan Liu Yu Lin Daxin Pang Qianqian Zhu Naixin Chen Jingjing Huang Xinze Chen Yixuan Yao Jingcang Yang Zicong Xie Xianya Huang Mengxin Liu Ran Zhang Qiuyan Li Yiliang Miao Jianhui Tian Xingxu Huang Hongsheng Ouyang Bofeng Liu Wei Xie Qi Zhou Zhonghua Liu Caihong Zheng Mingzhou Li Jianyong Han | 2022 | Cell Research2022，32，4： | 3 |
| 2 | Ambulatory blood pressure profile and stroke recurrence显示文摘Objectives To establish a new ambulatory blood pressure(ABP)parameter(24-hour ABP profile)and evaluated its performance on stroke outcome in ischaemic stroke(IS)or transient ischaemic attack(TIA)patients.Methods The prospective cohort consisted of 1996 IS/TIA patients enrolled for ABP monitoring and a 3-month follow-up for stroke recurrence as outcome.Profile groups of systolic blood pressure(SBP)were identified via an advanced functional clustering method,and the associations of the profile groups and conventional ABP parameters with stroke recurrence were examined in a Cox proportional hazards model.Results Three discrete profile groups(n=604,781 and 611 in profiles 1,2 and 3,respectively)in 24-hour ambulatory SBP were identified.Profile 1 resembled most to the normal diurnal blood pressure pattern;profile 2 also dropped at night,but climbed earlier and with higher morning surge;while profile 3 had sustained higher nocturnal SBP without significant nocturnal SBP decline.The incidence of stroke recurrence was 2.9%,3.9%and 5.5%in profiles 1,2 and 3,respectively.After adjustment for covariates,profile 3 was significantly associated with higher risk of stroke recurrence with profile 1 as reference(HR 1.76,95%CI:1.00 to 3.09),while no significant difference was observed between profiles 2 and 1(HR 1.22,95%CI:0.66 to 2.25).None of conventional ABP parameters showed significant associations with the outcome.Conclusions Ambulatory 24-hour SBP profile is associated with short-term stroke recurrence.Profiles of ABP may help improve identification of stroke recurrence by capturing the additive effects of individual ABP parameters. | Jie Xu Fei Jiang Anxin Wang Hui Zhi Yuan Gao Junping Tian Jinglin Mo Zimo Chen An-Ding Xu Benyan Luo Bo Hu Yuqing Zhang Xingquan Zhao Yilong Wang Hao Li Haipeng Shen Yongjun Wang | 2021 | Stroke & Vascular Neurology2021，6，3： | 3 |
| 3 | Green and scalable electrochemical routes for cost‐effective mass production of MXenes for supercapacitor electrodes显示文摘One of the most unique properties of two-dimensional carbides and nitrides of transition metals(MXenes)is their excellent water dispersibility and yet possessing superior electrical conductivity but their industrial-scale application is limited by their costly chemical synthesis methods.In this work,the niche feature of MXenes was capitalized in the packed-bed electrochemical reactor to produce MXenes at an unprecedented reaction rate and yield with minimal chemical waste.A simple NH4F solution was employed as the green electrolyte,which could be used repeatedly without any loss in its efficacy.Surprisingly,both fluoride and ammonium were found to play critical roles in the electrochemical etching,functionalization,and expansion of the layered parent materials(MAXs)through which the liberation of ammonia gas was observed.The electrochemically produced MXenes with excellent conductivity,applied as supercapacitor electrodes,could deliver an ultrahigh volumetric capacity(1408 F cm^(−3))and a volumetric energy density(75.8 Wh L^(−1)).This revolutionary green,energy-efficient,and scalable electrochemical route will not only pave the way for industrial-scale production of MXenes but also open up a myriad of versatile electrochemical modifications for improved functional MXenes. | Zimo Huang Jiadong Qin Yuxuan Zhu Kelin He Hao Chen Hui Ying Hoh Munkhbayar Batmunkh Tania MBenedetti Qitao Zhang Chenliang Su Shanqing Zhang Yu Lin Zhong | 2023 | Carbon Energy2023，5，10： | 1 |
| 4 | Metagenomic insights into the variation of bacterial communities and potential pathogenic bacteria in drinking water treatment and distribution systems显示文摘High-throughput sequencing of 16S rRNA gene amplicons was conducted to characterize the changing patterns of bacterial community and potential pathogens in full-scale drinking water treatment and distribution systems.Results showed that Actinobacteria was the predominant phylum in source water,while Proteobacteria dominated after chlorine disinfection and its relative abundance increased from 40.88%±9.45%to 67.86%±27.10%.The genera Pseudarthrobacter,Arenimonas,and Limnohabitans were effectively removed by chlorination,while Phreatobacter,Undibacterium,Pseudomonas,and Sphingomonas within the Proteobacteria phylum were greatly enriched after chlorination.Metagenomic analyses revealed the occurrence of 56 species of potential pathogenic bacteria within 17 genera in drinking water,mainly including Pseudomonas fluorescens and five mycobacteria species,which were also persistent in tap water samples.The bacteria were found to be involved in various pathways,among which considerable groups were related to human diseases,including infectious diseases and even cancers. | Ruiming Jiang Zihan Li Qisheng Li Yunqi Liu Yuning Zhu Zimo Chen Peng Liu Shuyu Jia Hongqiang Ren Xu-Xiang Zhang | 2022 | National Science Open2022，1，2： | 1 |
| 5 | Exploring the Roles of Single Atom in Hydrogen Peroxide Photosynthesis显示文摘This comprehensive review provides a deep exploration of the unique roles of single atom catalysts(SACs)in photocatalytic hydrogen peroxide(H_(2)O_(2))production.SACs offer multiple benefits over traditional catalysts such as improved efficiency,selectivity,and flexibility due to their distinct electronic structure and unique properties.The review discusses the critical elements in the design of SACs,including the choice of metal atom,host material,and coordination environment,and how these elements impact the catalytic activity.The role of single atoms in photocatalytic H_(2)O_(2)production is also analysed,focusing on enhancing light absorption and charge generation,improving the migration and separation of charge carriers,and lowering the energy barrier of adsorption and activation of reactants.Despite these advantages,several challenges,including H_(2)O_(2)decomposition,stability of SACs,unclear mechanism,and low selectivity,need to be overcome.Looking towards the future,the review suggests promising research directions such as direct utilization of H_(2)O_(2),high-throughput synthesis and screening,the creation of dual active sites,and employing density functional theory for investigating the mechanisms of SACs in H_(2)O_(2)photosynthesis.This review provides valuable insights into the potential of single atom catalysts for advancing the field of photocatalytic H_(2)O_(2)production. | Kelin He Zimo Huang Chao Chen Chuntian Qiu Yu Lin Zhong Qitao Zhang | 2024 | Nano-Micro Letters2024，16，2： | 0 |
| 6 | Low LDL-C level and intracranial haemorrhage risk after ischaemic stroke:a prospective cohort study显示文摘Background and purpose The Treat Stroke to Target trial has confirmed the benefit of targeting low-density lipoprotein cholesterol(LDL-C)of<1.8 mmol/L in patients who had an ischaemic stroke(IS).However,haemorrhagic risk brought by this target level(<1.8 mmol/L)or even lower level(<1.4 mmol/L)of LDL-C should also be concerned.In this study,we aimed to demonstrate whether low LDL-C could increase the intracranial haemorrhage risk following IS.Methods Patients who had an IS from China Stroke Center Alliance programme with complete baseline information were prospectively enrolled.793572 patients who had an IS were categorised into 6 groups according to LDL-C level(<1.40 mmol/L,1.40-1.79 mmol/L,1.80-2.59 mmol/L,2.60-2.99 mmol/L,3.00-4.89 mmol/L,≥4.90 mmol/L).The study outcome was defined as intracranial haemorrhage identified during hospitalisation.Logistic regression model was used to examine the association between different LDL-C levels and risk of intracranial haemorrhage.Results Compared with patients of LDL-C=1.80-2.59 mmol/L,both subgroups of LDL-C<1.40 mmol/L and LDL-C=1.40-1.79 mmol/L showed significantly higher risk of intracranial haemorrhage(OR=1.26,95%CI=1.18 to 1.35;OR=1.22,95%CI=1.14 to 1.30,respectively).Interaction effect was found to exist between the subgroups of intravenous thrombolytic therapy(p=0.04),rather than the subgroups of age,sex and body mass index.Moreover,the sensitivity analyses indicated that even patients who had an IS with minor stroke still suffered from the increased intracranial haemorrhage risk related to low LDL-C level.Conclusions Among patients who had an IS,the low LDL-C level(<1.4 mmol/L or<1.8 mmol/L)at baseline is associated with increased risk of intracranial haemorrhage during acute stage.While actively lowering LDL-C level for patients who had an IS,clinicians should also concern about the haemorrhagic risk associated with low LDL-C level. | Jie Xu Zimo Chen Meng Wang Jinglin Mo Jing Jing Gulbahram Yalkun Liye Dai Xia Meng Hao Li Zixiao Li Yongjun Wang | 2023 | Stroke & Vascular Neurology2023，8，2： | 0 |
| 7 | Cumulative burden of lipid profiles predict future incidence of ischaemic stroke and residual risk显示文摘Objectives Incident ischaemic stroke(IS)risk may increase not only with lipids concentration but also with longer duration of exposure.This study aimed to investigate the impact of cumulative burden of lipid profiles on risk of incident IS.Methods A total of 43836 participants were enrolled who participated in four surveys during 2006-2013.Individual cumulative lipid burden was calculated as number of years(2006-2013)multiplied by the levels of low-density lipoprotein cholesterol(LDL-C),total cholesterol(TC),high-density lipoprotein cholesterol(HDL-C),non-HDL C and triglyceride(TG),respectively.The primary outcome was defined as the incident IS during 2012-2017.Results During 4.67 years(±0.70 years)follow-up on average,we identified 1023(2.33%)incident IS.Compared with respective reference groups,the HRs(95%CIs)of the upper tertile in cumulative TG burden,cumulative LDL-C burden,cumulative TC burden and cumulative non-HDL C burden were 1.26 mmol/L(1.02-1.55 mmol/L),1.47 mmol/L(1.25-1.73 mmol/L),1.33 mmol/L(1.12-1.57 mmol/L)and 1.51 mmol/L(1.28-1.80 mmol/L)for incidence of IS,respectively.However,this association was not significant in cumulative HDL-C burden and IS(HR:1.09;95%CI:0.79 to 1.52),after adjustment for confounding variables.Among 16600 participants with low cumulative LDL-C burden,HRs(95%CI)for TC,TG,non-HDL C and HDL-C with IS were 1.63 mmol/L(1.03-2.57 mmol/L),1.65 mmol/L(1.19-2.31 mmol/L),1.57 mmol/L(1.06-2.32 mmol/L)and 0.98 mmol/L(0.56-1.72 mmol/L),respectively.Conclusions We observed the correlation between cumulative burden of lipid profiles,except for cumulative burden of HDL-C,with the risk of incident IS.Cumulative burden of TC,TG and non-HDL C may still predict IS in patients with low cumulative LDL-C burden.Trial registration number ChiCTR-TNRC 11001489. | Liye Dai Jie Xu Yijun Zhang Anxin Wang Zimo Chen Jinglin Mo Hao Li Xia Meng Shouling Wu Yongjun Wang | 2021 | Stroke & Vascular Neurology2021，6，4： | 0 |
| 8 | Developing potent BTK^(C481S)PROTACs for ibrutinib-resistant malignant lymphoma显示文摘Ibrutinib is a first-line treatment drug for B-cell malignancies.However,resistance to ibrutinib has been reported due to BTKC481Smutation.Although PROTAC strategy is expected to overcome this clinical resistance,it has limitations such as large molecular weight and moderate bioactivity,which restrict its potential clinical application.Herein,we report a new type of potent BTKC481S-targeting PROTAC degrader.Through design,computer-assisted optimization and SAR studies,we have developed a representative BTKC481Sdegrader L6 with a much smaller molecular weight and improved solubility.Notably,L6 demonstrates better BTK degrading activity and lower IC50value in ibrutinib-resistant cell line than the first-generation BTK degrader P13I.Optimization strategy of L6 provides a general approach in the development of PROTACs targeting BTK and other proteins for future study. | Yonghui Sun Xin Luo Zimo Yang Wenxing Lv Lixia Chen Hua Li Yu Rao | 2023 | Chinese Chemical Letters2023，34，6： | 0 |
