| 1 | 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents显示文摘Syncope belongs to the transient loss of consciousness(TLOC), characterized by a rapid onset, short duration, and spontaneous complete recovery. It is common in children and adolescents, accounting for 1% to 2% of emergency department visits.Recurrent syncope can seriously affect children's physical and mental health, learning ability and quality of life and sometimes cardiac syncope even poses a risk of sudden death. The present guideline for the diagnosis and treatment of syncope in children and adolescents was developed for guiding a better clinical management of pediatric syncope. Based on the globally recent development and the evidence-based data in China, 2018 Chinese Pediatric Cardiology Society(CPCS) guideline for diagnosis and treatment of syncope in children and adolescents was jointly prepared by the Pediatric Cardiology Society, Chinese Pediatric Society, Chinese Medical Association(CMA)/Committee on Pediatric Syncope, Pediatricians Branch, Chinese Medical Doctor Association(CMDA)/Committee on Pediatric Cardiology, Chinese College of Cardiovascular Physicians, Chinese Medical Doctor Association(CMDA)/Pediatric Cardiology Society, Beijing Pediatric Society, Beijing Medical Association(BMA). The present guideline includes the underlying diseases of syncope in children and adolescents, the diagnostic procedures, methodology and clinical significance of standing test and headup tilt test, the clinical diagnosis vasovagal syncope, postural orthostatic tachycardia syndrome, orthostatic hypotension and orthostatic hypertension, and the treatment of syncope as well as follow-up. | Cheng Wang Yaqi Li Ying Liao Hong Tian Min Huang Xiangyu Dong Lin Shi Jinghui Sun Hongfang Jin Junbao Du Jindou An Jie Chen Mingwu Chen Qi Chen Sun Chen Yonghong Chen Zhi Chen Adolphus Kai-tung Chau Junbao Du Zhongdong Du Junkai Duan Hongyu Duan Xiangyu Dong Lin Feng Lijun Fu Fangqi Gong Yonghao Gui Ling Han Zhenhui Han Bing He Zhixu He Xiufen Hu Yimin Hua Guoying Huang Min Huang Ping Huang Yujuan Huang Hongfang Jin Mei Jin Bo Li Fen Li Tao Li Xiaohui Li Xiaoyan Liu Yan Li Haitao Lv Tiewei Lv Zipu Li Luyi Ma Silin Pan Yusheng Pang Hua Peng Yuming Qin Jie Shen Lin Shi Kun Sun Jinghui Sun Hong Tian Jie Tian Cheng Wang Hong Wang Lei Wang Jinju Wang Wendi Wang Yuli Wang Rongzhou Wu Tianhe Xia Yanyan Xiao Chunhong Xie Yanlin Xing Zhenyu Xiong Baoyuan Xu Yi Xu Hui Yan Shiwei Yang Qijian Yi Xia Yu Xianyi Yu Yue Yuan Hongyan Zhang Huili Zhang Li Zhang Qingyou Zhang Xi Zhang Yanmin Zhang Zhiwei Zhang Cuifen Zhao Bin Zhou Hua Zhu | 2018 | Science Bulletin2018，63，23： | 54 |

| 3 | Highly crystalline ReSe2 atomic layers synthesized by chemical vapor transport显示文摘Two-dimensional (2D) anisotropic rhenium diselenide (ReSe2) has attracted lots ofattention due to its promising applications in electronics and optoelectronics. However,controlled synthesis of high quality ultrathin ReSe2 remains as a challenge.Here we developed an approach for synthesizing high quality 2D ReSe2 flakes witha thickness down to monolayer by chemical vapor transport (CVT) through carefullytuning the growth kinetics. The atomic structures and anisotropy of theobtained ReSe2 flakes were intensively characterized with scanning transmissionelectron microscope and angle-resolved polarized Raman spectroscopy. Fieldeffecttransistors fabricated on the CVT-grown ReSe2 flakes showed n-typesemiconducting behavior with an on/off current ratio of 105 and a mobility up to5 cm2 V−1 s−1, which is comparable to mechanically exfoliated flakes and isobvious higher than the samples synthesized with other approaches. This study notonly make high quality 2D ReSe2 easily accessible for both fundamental and applicationexplorations but also sheds new lights on the chemical synthesis of otheranisotropic 2D materials. | Lei Xing Xingxu Yan Jingying Zheng Guanchen Xu Zhixing Lu Lina Liu Jinghui Wang Peng Wang Xiaoqing Pan Liying Jiao | 2019 | InfoMat2019，1，4： | 2 |
| 4 | Mitogen activated protein kinase signaling pathways participate in the active principle region of Buyang Huanwu decoction-induced differentiation of bone marrow mesenchymal stem cells显示文摘Our preliminary studies confirmed that an active principle region of Buyang Huanwu decoction, comprising alkaloid, polysaccharide, aglycon, glucoside and volatile oil, can induce bone marrow mesenchymal stem cell differentiation into neurons. Mitogen-activated protein kinase signaling was identified as one of the key pathways underlying this differentiation process. The present study shows phosphorylated extracellular signal-regulated protein kinase and phosphorylated p38 protein expression was increased after differentiation. Cellular signaling pathway blocking agents, PD98059 and SB203580, inhibited extracellular signal-regulated protein kinase and p38 in mitogen-activated protein kinase signaling pathways respectively. mRNA and protein expression of the neuronal marker, neuron specific enolase, and neural stem cell marker, nestin, were decreased in bone marrow mesenchymal stem cells after treatment with the active principle region of Buyang Huanwu decoction. Experimental findings indicate that, extracellular signal-regulated protein kinase and p38 in mitogen-activated protein kinase signaling pathways participate in bone marrow mesenchymal stem cell differentiation into neuron-like cells, induced by the active principle region of Buyang Huanwu decoction. | Jinghui Zheng Jian Liang Xin Deng Xiaofeng Chen Fasheng Wu Xiaofang Zhao Yuan Luo Lei Fu Zuling Jiang | 2012 | Neural Regeneration Research2012，7，18： | 2 |
| 5 | FOXO3-engineered human mesenchymal progenitor cells efficiently promote cardiac repair after myocardial infarction显示文摘Dear Editor,Myocardial infarction(MI)is the irreversible cardiomyocyte death resulting from prolonged oxygen deprivation due to obstructed blood supply(ischemia),leading to contractile dysfunction and cardiac remodeling.In recent decades,stem cell transplantation has been extensively investigated for the repair of injured heart in animal studies and clinical trials(Kanelidis et al.,2017;Gyongyosi et al.,2018). | Jinghui Lei Si Wang Wang Kang Qun Chu Zunpeng Liu Liang Sun Yun Ji Concepcion Rodriguez Esteban Yan Yao Juan Carlos Izpisua Belmonte Piu Chan Guang-Hui Liu Weiqi Zhang Moshi Song Jing Qu | 2021 | Protein & Cell2021，12，2： | 1 |
| 6 | Exosomes from antler stem cells alleviate mesenchymal stem cell senescence and osteoarthritis显示文摘Dear Editor,Stem cell therapy holds enormous and revolutionary promise to treat various age-related diseases,such as diabetes,heart failure,and Parkinson’s disease.However,low retention and survival rate of delivered stem cells,partially due to immunological rejection,constitute major hurdles for the clinical implementation of stem cell therapy(Lei et al.,2021a).Since mounting evidence showed that several types of stem cells mainly exert their therapeutic effects through the secretion of paracrine effects,exosomes,which are released by stem cells and execute most paracrine functions,have begun to draw attention in the field(Tran and Damaser,2015).Exosomes are membrane-enclosed vesicles with an average diameter of∼100 nanometers secreted by the cells,containing cytokines. | Jinghui Lei Xiaoyu Jiang Wei Li Jie Ren Datao Wang Zhejun Ji Zeming Wu Fang Cheng Yusheng Cai Zheng-Rong Yu Juan Carlos Izpisua Belmonte Chunyi Li Guang-Hui Liu Weiqi Zhang Jing Qu Si Wang | 2022 | Protein & Cell2022，13，3： | 1 |

| 9 | Single nucleotide polymorphisms in the human corticosteroid-binding globulin promoter alter transcriptional activity显示文摘Corticosteroid-binding globulin(CBG) is a high-affinity plasma protein that transports glucocorticoids and progesterone.Others and we have reported non-synonymous single nucleotide polymorphisms(SNPs) that influence CBG production or steroid-binding activity.However,no promoter polymorphisms affecting the transcription of human CBG gene(Cbg) have been reported.In the present study we investigated function implications of six promoter SNPs,including 26 C/G,54 C/T,144 G/C,161 A/G,205 C/A,and 443/444 AG/,five of which are located within the first 205 base pairs of 5'-flanking region and close to the highly conserved footprinted elements,TATA-box,or CCAAT-box.Luciferase reporter assays demonstrated that basal activity of the promoter carrying 54 T or 161 G was significantly enhanced.The first three polymorphisms,26 C/G,54 C/T,and 144 G/C located close to the putative hepatic nuclear factor(HNF) 1 binding elements,altered the transactivation effect of HNF1.We also found a negative promoter response to dexamethasone-activated glucocorticoid receptor(GR),although none of the SNPs affected its transrepression function.Our results suggest that human Cbg 26 C/G,54 C/T,144 G/C,and 161 A/G promoter polymorphisms alter transcriptional activity,and further studies are awaited to explore their association with physiological and pathological conditions. | LI Yue WU Liang LEI JingHui ZHU Cheng WANG HongMei YU XiaoGuang LIN HaiYan | 2012 | Science China(Life Sciences)2012，55，8： | 1 |
| 10 | Study on Deactivation by Sulfur and Regeneration of Pd/C Catalyst in Hydrogenation of N-(3-nitro-4-methoxyphenyl) Acetamide显示文摘Deactivation of Pd/C catalyst often occurs in liquid hydrogenation using industrial materials. For in-stance, the Pd/C catalyst is deactivated severely in the hydrogenation of N-(3-nitro-4-methoxyphenyl) acetamide. In this study, the chemisorption of sulfur on the surface of deactivated Pd/C was detected by energy dispersive spec-trometer and X-ray photoelectron spectroscopy. Sulfur compounds poison the Pd/C catalyst and increase the forma-tion of azo deposit, reducing the activity of catalyst. We report a mild method to regenerate the Pd/C catalyst: wash the deposit by N,N-dimethylformamide and oxidize the chemisorbed sulfur by hot air. The regenerated Pd/C cata-lyst can be reused at least ten runs with stable activity. | ZHANG Qunfeng LU Jinghui MA Lei LU Chunshan HIU Wei LI Xiaonian | 2013 | Chinese Journal of Chemical Engineering2013，21，6： | 1 |
| 11 | The enhanced genomic 6mA metabolism contributes to the proliferation and migration of TSCC cells显示文摘In contrast to the well-established genomic 5-methylcytosine(5mC),the existence of N^(6)-methyladenine(6 mA)in eukaryotic genomes was discovered only recently.Initial studies found that it was actively regulated in cancer cells,suggesting its involvement in the process of carcinogenesis.However,the contribution of 6 mA in tongue squamous cell carcinoma(TSCC)still remains uncharacterized.In this study,a pan-cancer type analysis was first performed,which revealed enhanced 6mA metabolism in diverse cancer types.The study was then focused on the regulation of 6 mA metabolism,as well as its effects on TSCC cells.To these aspects,genome 6mA level was found greatly increased in TSCC tissues and cultured cells.By knocking down 6mA methylases N6AMT1 and METTL4,the level of genomic 6mA was decreased in TSCC cells.This led to suppressed colony formation and cell migration.By contrast,knockdown of 6mA demethylase ALKBH1 resulted in an increased 6 mA level,enhanced colony formation,and cell migration.Further study suggested that regulation of the NF-κB pathway might contribute to the enhanced migration of TSCC cells.Therefore,in the case of TSCC,we have shown that genomic 6mA modification is involved in the proliferation and migration of cancer cells. | Lei Xi Ying Yang Ying Xu Fangming Zhang Jinghui Li Xiyang Liu Zhenxi Zhang Quan Du | 2022 | International Journal of Oral Science2022，14，1： | 0 |

| 14 | CRL2^(APPBP2)-mediated TSPYL2 degradation counteracts human mesenchymal stem cell senescence显示文摘Cullin-RING E3 ubiquitin ligases(CRLs),the largest family of multi-subunit E3 ubiquitin ligases in eukaryotic cells,represent core cellular machinery for executing protein degradation and maintaining proteostasis.Here,we asked what roles Cullin proteins play in human mesenchymal stem cell(hMSC)homeostasis and senescence.To this end,we conducted a comparative aging phenotype analysis by individually knocking down Cullin members in three senescence models:replicative senescent hMSCs,Hutchinson-Gilford Progeria Syndrome hMSCs,and Werner syndrome hMSCs.Among all family members,we found that CUL2 deficiency rendered hMSCs the most susceptible to senescence.To investigate CUL2-specific underlying mechanisms,we then applied CRISPR/Cas9-mediated gene editing technology to generate CUL2-deficient human embryonic stem cells(hESCs).When we differentiated these into h MSCs,we found that CUL2 deletion markedly accelerates hMSC senescence.Importantly,we identified that CUL2 targets and promotes ubiquitin proteasome-mediated degradation of TSPYL2(a known negative regulator of proliferation)through the substrate receptor protein APPBP2,which in turn downregulates one of the canonical aging marker-P21^(waf1/cip1),and thereby delays senescence.Our work provides important insights into how CRL2^(APPBP2)-mediated TSPYL2 degradation counteracts hMSC senescence,providing a molecular basis for directing intervention strategies against aging and aging-related diseases. | Daoyuan Huang Qian Zhao Kuan Yang Jinghui Lei Ying Jing Hongyu Li Chen Zhang Shuai Ma Shuhui Sun Yusheng Cai Guibin Wang Jing Qu Weiqi Zhang Si Wang Guang-Hui Liu | 2024 | Science China(Life Sciences)2024，67，3： | 0 |

| 17 | Clinical Epidemiology,Illness Profiles,and the Implication of COVID-19 Before and After the Nationwide Omicron Outbreak During the Winter of 2022显示文摘China.In this study,we aimed to investigate the clinical characteristics and outcomes of patients with coronavirus disease 2019(COVID-19)in the Beijing region.Methods:In this retrospective study,we enrolled inpatients admitted for COVID-19 in the Fifth Medical Center of Chinese PLA General Hospital in Beijing between November 10,2022,and January 30,2023.Demographic and clinical features and treatment outcomeswere comprehensively analyzed.We used logistic regression and linear regression analyses to explore the risk factors associated with disease severity and time of nucleic acid conversion,respectively.Results:A total of 1010 hospitalized patients with COVID-19 were enrolled.The median age was 43.0 years(interquartile range,28.0–63.0),and patients aged<60 years and≥60 years comprised 71.2%and 28.8%of total included patients,respectively.The clinical classification of mild(74.6%,753/1010),moderate(21.0%,212/1010),severe(2.7%,27/1010),and unidentified(1.8%,18/1010)was separately recorded;1005 patients were discharged,and 5 patients died in the hospital.The outbreak of the emerging epidemic witnessed an evident increase in the proportion of moderate(42.9%vs.16.4%)and severe(10.3%vs.1.1%)cases after December 7,2022.Patients with a moderate/severe classification had higher levels of procalcitonin,IL-6,serum ferritin,C-reactive protein,lactic dehydrogenase,serum urea nitrogen,and D-dimer and lower counts of CD4+T,CD8+T,and B cells(all P<0.001).Multivariable regression analysis revealed that increased odds of disease severity were associated with the following factors:age≥60 years,IL-6>7 pg/mL,lactic dehydrogenase level>245 U/L,cough,and fever at admission.Age≥80 years and chronic lung diseasewere independent risk factors in the nonmild group in elderly patients.In addition,the duration for nucleic acid to turn negativewas approximately 5.0 d(interquartile range,3.0–7.0).Prolonged time of nucleic acid conversion was associated with age≥60 years,serum urea nitrogen level>8.2 mmol/L,neutrophil count>7×10^(9)/L,and the presence of a chronic lung disease or carcinoma.Finally,unvaccinated patients accounted for 37.3%of enrolled patients;children and the elder people accounted for approximately half of that.The univariable analysis found that booster doses reduced disease severity and shortened the time of nucleic acid conversion in elderly patients.Conclusions:The outbreak ofOmicron rapidly increased the number of patientswith COVID-19 in Beijing.In elderly patients,booster doses may reduce disease severity and shorten the time of nucleic acid conversion.Healthcare systems should be optimized before an emerging epidemic outbreak. | Yuming Guo Zhe Xu Wen-Xin Wang Cheng Zhen Jinhua Hu Jinsong Mu Chengcheng Ji Xin Yuan Ruonan Xu Lei Huang Lei Shi Fanping Meng Junliang Fu Shuangnan Zhou Siyu Wang Fengyi Li Bo Tu Dawei Zhang Huihuang Huang Yufeng Mao Wen Xu Chao Zhang Xiuying Mu Jun Zhao Bo Jin Haibin Su Yinying Lu Yongqian Cheng Dong Ji Shaoli You Jinghui Dong Changchun Liu Mengmeng Zhang Yuanyuan Li Tianjun Jiang Yonggang Li Fu-Sheng Wang | 2023 | Infectious Diseases & Immunity2023，3，4： | 0 |
| 18 | A single-nucleus transcriptomic atlas of primate testicular aging reveals exhaustion of the spermatogonial stem cell reservoir and loss of Sertoli cell homeostasis显示文摘The testis is pivotal for male reproduction,and its progressive functional decline in aging is associated with infertility.However,the regulatory mechanism underlying primate testicular aging remains largely elusive.Here,we resolve the aging-related cellular and molecular alterations of primate testicular aging by establishing a single-nucleus transcriptomic atlas.Gene-expression patterns along the spermatogenesis trajectory revealed molecular programs associated with attrition of spermatogonial stem cell reservoir,disturbed meiosis and impaired spermiogenesis along the sequential continuum.Remarkably,Sertoli cell was identified as the cell type most susceptible to aging,given its deeply perturbed age-associated transcriptional profiles.Concomitantly,downregulation of the transcription factor Wilms'Tumor 1(WTi),essential for Sertoli cell homeostasis,was associated with accelerated cellular senescence,disrupted tight junctions,and a compromised cell identity signature,which altogether may help create a hostile microenvironment for spermatogenesis.Collectively,our study depicts in-depth transcriptomic traits of non-human primate(NHP)testicular aging at single-cell resolution,providing potential diagnostic biomarkers and targets for therapeutic interventions against testicular aging and age-related male reproductive diseases. | Daoyuan Huang Yuesheng Zuo Chen Zhang Guoqiang Sun Ying Jing Jinghui Lei Shuai Ma Shuhui Sun Huifen Lu Yusheng Cai Weiqi Zhang Fei Gao Andy Peng Xiang Juan Carlos Izpisua Belmonte Guang-Hui Liu Jing Qu Si Wang | 2023 | Protein & Cell2023，14，12： | 0 |
| 19 | 植物功能群在调控气候和土壤因子对蒙古高原草原群落物种丰富度和生物量影响中的作用显示文摘植物功能群组成主要受环境因素驱动,同时植物功能群组成也是影响草地生物多样性和生产力的主要因素之一。因此,理解植物功能群在调控环境因素对生态系统功能和生物多样性影响中可能发挥的作用至关重要。通过对蒙古高原草原65个样点的植物生物量和物种丰富度的调查,将157种多年生草本植物分为两种植物功能群(即禾草和杂类草)。通过随机森林模型和普通最小二乘回归,确定与植物功能群物种丰富度和地上生物量显著相关的环境因素(即干燥度、土壤总氮和pH),并利用结构方程模型探讨筛选出的环境因素与群落物种丰富度和生物量间的关系,以及植物功能群在驱动这种关系中发挥的作用。干燥度与禾草、杂类草以及整个群落的地上生物量和物种丰富度均呈显著的单峰关系。所有的物种丰富度和生物量指标均与土壤总氮和pH值显著相关。禾草在维持蒙古高原草原生态系统群落生物量中起着关键作用,并受气候因素的直接影响。而杂类草物种丰富度决定了群落总丰富度,并受到土壤因素直接的调控。因此,群落组成在调控环境因素对群落生物量和植物多样性的影响中起着关键作用。 | Zijing Li Maowei Liang Zhiyong Li Pierre Mariotte Xuze Tong Jinghui Zhang Lei Dong Ying Zheng Wenhong Ma Liqing Zhao Lixin Wang Lu Wen Indree Tuvshintogtokh Elise S.Gornish Zhenhua Dang Cunzhu Liang Frank Yonghong Li | 2021 | Journal of Plant Ecology2021，14，4： | 0 |
| 20 | Human EsC-derived vascular cells promote vascular regeneration in a HIF-1a dependent manner显示文摘Hypoxia-inducible factor(HIF-1α),a core transcription factor responding to changes in cellular oxygen levels,is closely associated with a wide range of physiological and pathological conditions.However,its differential impacts on vascular cell types and molecular programs modulating human vascular homeostasis and regeneration remain largely elusive.Here,we applied CRISPR/Cas9-mediated gene editing of human embryonic stem cells and directed differentiation to generate HIF-ia-deficient human vascular cells including vascular endothelial cells,vascular smooth muscle cells,and mesenchymal stem cells(MsCs),as a platform for discovering cell type-specific hypox-ia-induced response mechanisms.Through comparative molecular profiling across cell types under normoxic and hypoxic conditions,we provide insight into the indispensable role of HIF-1αin the promotion of ischemic vascular regeneration.We found human MSCs to be the vascular cell type most susceptible to HIF-1a deficiency,and that transcriptional inactivation of ANKZF1,an effector of HIF-1a,impaired pro-angiogenic processes.Altogether,our findings deepen the understanding of HIF-ia in human angiogenesis and support further explorations of novel therapeutic strategies of vascular regeneration against ischemic damage. | Jinghui Lei Xiaoyu Jiang Daoyuan Huang Ying Jing Shanshan Yang Lingling Geng Yupeng Yan Fangshuo Zheng Fang Cheng Weiqi Zhang Juan Carlos Izpisua Belmonte Guang-Hui Liu Si Wang Jing Qu | 2024 | Protein & Cell2024，15，1： | 0 |
