| 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 |
| 2 | PI3K/Akt/mTOR signaling orchestrates the phenotypic transition and chemo-resistance of small cell lung cancer显示文摘Small cell lung cancer(SCLC)is a phenotypically heterogeneous disease with an extremely poor prognosis,which is mainly attributed to the rapid development of resistance to chemotherapy.However,the relation between the growth phenotypes and chemo-resistance of SCLC remains largely unclear.Through comprehensive bioinformatic analyses,we found that the heterogeneity of SCLC phenotype was significantly associated with different sensitivity to chemotherapy.Adherent or semiadherent SCLC cells were enriched with activation of the PI3K/Akt/mTOR pathway and were highly chemoresistant.Mechanistically,activation of the PI3K/Akt/mTOR pathway promotes the phenotypic transition from suspension to adhesion growth pattern and confers SCLC cells with chemo-resistance.Such chemo-resistance could be largely overcome by combining chemotherapy with PI3K/Akt/mTOR pathway inhibitors.Our findings support that the PI3K/Akt/mTOR pathway plays an important role in SCLC phenotype transition and chemo-resistance,which holds important clinical implications for improving SCLC treatment. | Xuefeng Li Cheng Li Chenchen Guo Qiqi Zhao Jiayu Cao Hsin-Yi Huang Meiting Yue Yun Xue Yujuan Jin Liang Hu Hongbin Ji | 2021 | Journal of Genetics and Genomics2021，48，7： | 5 |

| 8 | Kinetically accelerated and high-mass loaded lithium storage enabled by atomic iron embedded carbon nanofibers显示文摘Carbonaceous materials represent the dominant choice of materials for anodic lithium storage in many energy storage devices.Nevertheless,the nonpolar carbonaceous materials offer weak adsorption toward Li+that largely denies the high-rate Li+storage.Herein,the atomic Fe sites decorated carbon nanofibers(AICNFs)facilely produced by electrospinning are reported for kinetically accelerated Li+storage.Theoretical calculation reveals that the atomic Fe sites possess coordination unsaturated electronic configuration,enabling suitable bonding energy and facilitated diffusion path of Li+.As a result,the optimal structure displays a high capacitive contribution up to 95.9%at a scan rate of 2.0 mV·s^(−1).In addition,ultrahigh capacity retention of 97%is afforded after 5,000 cycles at a current density of 3 A·g^(−1).Moreover,the interlaced fiber structure enabled by electrospinning benefits structural stability and improved conductivity even at thick electrodes,thus allowing a high areal capacity of 1.76 mAh·cm−2 at a loading of 8 mg·cm−2.Because of these structure and performance merits,the lithium-ion capacitor containing the AICNF-based anode delivers a high energy density and large power density. | Qian Xu Yanan Li Chenghao Wu Xitong Sun Qiang Li Huabin Zhang Le Yu Yuanyuan Pan Yujuan Wang Shiwei Guo Mengdi Zhang Han Hu Mingbo Wu | 2022 | Nano Research2022，15，7： | 0 |
| 9 | Oxidative stress-triggered Wnt signaling perturbation characterizes the tipping point of lung adeno-to-squamous transdifferentiation显示文摘Lkb1 deficiency confers the Kras-mutant lung cancer with strong plasticity and the potential for adeno-to-squamous transdifferentiation(AST).However,it remains largely unknown how Lkb1 deficiency dynamically regulates AST.Using the classical AST mouse model(Kras LSL-G12D/+;Lkb1flox/flox,KL),we here comprehensively analyze the temporal transcriptomic dynamics of lung tumors at different stages by dynamic network biomarker(DNB)and identify the tipping point at which the Wnt signaling is abruptly suppressed by the excessive accumulation of reactive oxygen species(ROS)through its downstream effector FOXO3A.Bidirectional genetic perturbation of the Wnt pathway using two different Ctnnb1 conditional knockout mouse strains confirms its essential role in the negative regulation of AST.Importantly,pharmacological activation of the Wnt pathway before but not after the tipping point inhibits squamous transdifferentiation,highlighting the irreversibility of AST after crossing the tipping point.Through comparative transcriptomic analyses of mouse and human tumors,we find that the lineage-specific transcription factors(TFs)of adenocarcinoma and squamous cell carcinoma form a“Yin-Yang”counteracting network.Interestingly,inactivation of the Wnt pathway preferentially suppresses the adenomatous lineage TF network and thus disrupts the“Yin-Yang”homeostasis to lean towards the squamous lineage,whereas ectopic expression of NKX2-1,an adenomatous lineage TF,significantly dampens such phenotypic transition accelerated by the Wnt pathway inactivation.The negative correlation between the Wnt pathway and AST is further observed in a large cohort of human lung adenosquamous carcinoma.Collectively,our study identifies the tipping point of AST and highlights an essential role of the ROS-Wnt axis in dynamically orchestrating the homeostasis between adeno-and squamous-specific TF networks at the AST tipping point. | Zhaoyuan Fang Xiangkun Han Yueqing Chen Xinyuan Tong Yun Xue Shun Yao Shijie Tang Yunjian Pan Yihua Sun Xue Wang Yujuan Jin Haiquan Chen Liang Hu Lijian Hui Lin Li Luonan Chen Hongbin Ji | 2023 | Signal Transduction and Targeted Therapy2023，8，2： | 0 |
| 10 | Identification of TAZ as the essential molecular switch in orchestrating SCLC phenotypic transition and metastasis显示文摘Small-cell lung cancer(SCLC)is a recalcitrant cancer characterized by high metastasis.However,the exact cell type contributing to metastasis remains elusive.Using a Rb1^(L/L)/Trp53^(L/L) mouse model,we identify the NCAM^(hi)CD44^(lo/–) subpopulation as the SCLC metastasizing cell(SMC),which is progressively transitioned from the non-metastasizing NCAM^(lo)CD44^(hi) cell(non-SMC).Integrative chromatin accessibility and gene expression profiling studies reveal the important role of the SWI/SNF complex,and knockout of its central component,Brg1,significantly inhibits such phenotypic transition and metastasis.Mechanistically,TAZ is silenced by the SWI/SNF complex during SCLC malignant progression,and its knockdown promotes SMC transition and metastasis.Importantly,ectopic TAZ expression reversely drives SMC-to-non-SMC transition and alleviates metastasis.Single-cell RNA-sequencing analyses identify SMC as the dominant subpopulation in human SCLC metastasis,and immunostaining data show a positive correlation between TAZ and patient prognosis.These data uncover high SCLC plasticity and identify TAZ as the key molecular switch in orchestrating SCLC phenotypic transition and metastasis. | Yujuan Jin Qiqi Zhao Weikang Zhu Yan Feng Tian Xiao Peng Zhang Liyan Jiang Yingyong Hou Chenchen Guo Hsinyi Huang Yabin Chen Xinyuan Tong Jiayu Cao Fei Li Xueliang Zhu Jun Qin Dong Gao Xin-Yuan Liu Hua Zhang Luonan Chen Roman KThomas Kwok-Kin Wong Lei Zhang Yong Wang Liang Hu Hongbin Ji | 2022 | National Science Review2022，9，7： | 0 |
| 11 | Immunity-and-matrix-regulatory cells enhance cartilage regeneration for meniscus injuries: a phase I dose-escalation trial显示文摘Immunity-and-matrix-regulatory cells(IMRCs)derived from human embryonic stem cells have unique abilities in modulating immunity and regulating the extracellular matrix,which could be mass-produced with stable biological properties.Despite resemblance to mesenchymal stem cells(MSCs)in terms of self-renew and tri-lineage differentiation,the ability of IMRCs to repair the meniscus and the underlying mechanism remains undetermined.Here,we showed that IMRCs demonstrated stronger immunomodulatory and pro-regenerative potential than umbilical cord MSCs when stimulated by synovial fluid from patients with meniscus injury.Following injection into the knees of rabbits with meniscal injury,IMRCs enhanced endogenous fibrocartilage regeneration.In the dose-escalating phase I clinical trial(NCT03839238)with eighteen patients recruited,we found that intra-articular IMRCs injection in patients was safe over 12 months post-grafting.Furthermore,the effective results of magnetic resonance imaging(MRI)of meniscus repair and knee functional scores suggested that 5×107 cells are optimal for meniscus injury treatment.In summary,we present the first report of a phase I clinical trial using IMRCs to treat meniscus injury.Our results demonstrated that intra-articular injection of IMRCs is a safe and effective therapy by providing a permissive niche for cartilage regeneration. | Liangjiang Huang Song Zhang Jun Wu Baojie Guo Tingting Gao Sayed Zulfiqar Ali Shah Bo Huang Yajie Li Bo Zhu Jiaqi Fan Liu Wang Yani Xiao Wenjing Liu Yao Tian Zhengyu Fang Yingying Lv Lingfeng Xie Sheng Yao Gaotan Ke Xiaolin Huang Ying Huang Yujuan Li Yi Jia Zhongwen Li Guihai Feng Yan Huo Wei Li Qi Zhou Jie Hao Baoyang Hu Hong Chen | 2023 | Signal Transduction and Targeted Therapy2023，8，12： | 0 |
| 12 | Non-escaping frost tolerant QTL linked genetic loci at reproductive stage in six wheat DH populations显示文摘Reproductive stage frost poses a major constraint for wheat production in countries such as Australia.However,little progress has been made in identifying key genes to overcome the constraint.In the present study,a severe frost event hit two large-scale field trials consisting of six doubled haploid(DH)wheat populations at reproductive stage(young microspore stage)in Western Australia,leading to the identification of 30 robust frost QTL on 17 chromosomes.The major 18 QTL with the phenotype variation over 9.5%were located on 13 chromosomes including 2 A,2 B,2 D,3 A,4 A,4 B,4 D,5 A,5 D,6 D,7 A,7 B and7 D.Most frost QTL were closely linked to the QTL of anthesis,maturity,Zadok stages as well as linked to anthesis related genes.Out of those,six QTL were repetitively detected on the homologous regions on 2 B,4 B,4 D,5 A,5 D,7 A in more than two populations.Results showed that the frost damage is associated with alleles of Vrn-A1 a,Vrn-D1 a,Rht-B1 b,Rht-D1 b,and the high copy number of Ppd-B1.However,anthesis QTL and anthesis related genes of Vrn-B1 a and Ta FT3-1 B on chromosomes 5 B and 1 B did not lead to frost damage,indicating that these early-flowering phenotype related genes are compatible with frost tolerance and thus can be utilised in breeding.Our results also indicate that wild-type alleles Rht-B1 a and Rht-D1 a can be used when breeding for frost-tolerant varieties without delaying flowering time. | Jingjuan Zhang MD Shahidul Islam Yun Zhao Masood Anwar Zaid Alhabbar Maoyun She Rongchang Yang Angela Juhasz Guixiang Tang Jiansheng Chen Hang Liu Yanjie Jiang Shengnan Zhai Xin Hu Junkang Rong Yingquan Zhang Yebo Qin Qier Liu Zitong Yu Yujuan Zhang Sadegh Balotf Mirza Dowla Sonia Afrin Nandita Roy Md Resad Mallik Md Atik Us Saieed Shanjida Rahman Nigarin Sultana Sarah Al-Sheikh Ahmed Chris Florides Kefei Chen Darshan Sharma Nathan Height Ben Biddulph Meiqin Lu Jorge EMayer Wujun Ma | 2022 | The Crop Journal2022，10，1： | 0 |

| 15 | Association of SOST gene polymorphisms with peak bone mineral density in Chinese nuclear families with male-offspring显示文摘Peak bone mineral density(BMD)achieved during early adulthood is a highly heritable trait and a strong determinant of subsequent osteoporotic fracture risk.Evidence has already suggested that 50–80% of the variance in peak BMD is genetically determined [1].Human SOST gene comprises three exons and two introns,mapping to chromosomal region 17q12–q21.It inhibits osteoblastic bone formation by inhibiting the Wnt signaling pathway,which is critically important for the development and function of osteoblasts [2].Our previous study in large samples of postmenopausal Chinese women showed that the polymorphisms in the SOST gene are associated with BMD of the lumbar spine [3],but little is known in men.Thus,the objective of this study was to investigate whether polymorphisms in the SOST gene are associated with variations of peak BMD in Chinese nuclear families with male-offspring. | Luyue Qi Shoukui Xiang Li Li Jinwei He Wenzhen Fu Yujuan Liu Yunqiu Hu Zhenlin Zhang | 2019 | Acta Biochimica et Biophysica Sinica2019，51，3： | 0 |
| 16 | Effects of Huangzhou Radish Powder on the Quality of Silver Carp Surimi Products显示文摘[Objectives]This study was conducted to improve the quality of frozen silver carp surimi products.[Methods]Huangzhou radish powder and silver carp surimi were used as raw materials to analyze the effects of different amounts(1%,2%,3%,4%,5%)of Huangzhou radish powder on the water-holding capacity,cooking loss rate,whiteness value,TPA,gel strength and sensory quality of surimi products.[Results]When the addition amount of Huangzhou radish powder was 1%,water-holding capacity,hardness,chewiness and the gel strength of the surimi product reached their maximum values,which were 86.86%,3470.36 g,2628.50 g and 707.48 g·mm,respectively.Meanwhile,the cooking loss rate was reduced to a minimum value(13.66%),and the sensory quality reached the best.The whiteness of surimi products showed a decreasing trend with the increase of the addition amount of Huangzhou radish powder.However,the whiteness of the surimi product was not significantly affected when the addition amount of Huangzhou radish powder was 1%.Therefore,when the addition amount of Huangzhou radish powder was 1%,the quality of surimi products could be improved.[Conclusions]This study provides a new idea for the development and utilization of Huangzhou radish. | Qi YANG Xiaohong LIU Xinghui TIAN Yujuan JIN Yanyu YANG Fa QIU Siyao MA Peng WU Ting HU | 2023 | Agricultural Biotechnology2023，12，2： | 0 |
| 17 | Understanding SCLC heterogeneity and plasticity in cancer metastasis and chemotherapy resistance显示文摘Small cell lung cancer(SCLC)accounts for approximately 15%of all lung cancer cases and features a strong predilection for early metastasis and extremely poor prognosis.Despite being highly sensitive to chemotherapy and/or radiotherapy initially,most SCLC patients develop therapeutic resistance within one year and die of distant metastases.Multiple studies have revealed the high heterogeneity and strong plasticity of SCLC associated with frequent metastases and early development of therapeutic resistance as well as poor clinical outcome.Importantly,different SCLC subtypes are associated with different therapeutic vulnerabilities,and the inflamed subtype tends to have the best response to immunotherapy,which highlights the importance of precision medicine in the clinic.Here,we review recent advances in ScLc heterogeneity and plasticity and their link to distant metastases and chemotherapy resistance.We hope that a better understanding of the molecular mechanisms underlying SCLC malignant progression will help to develop better intervention strategies for this deadly disease. | Yujuan Jin Yanxu Chen Zhen Qin Liang Hu Chenchen Guo Hongbin Ji | 2023 | Acta Biochimica et Biophysica Sinica2023，55，6： | 0 |
| 18 | Targeting HSPA1A in ARID2-deficient lung adenocarcinoma显示文摘Somatic mutations of the chromatin remodeling gene ARID2 are observed in~7%of human lung adenocarcinomas(LUADs).However,the role of ARID2 in the pathogenesis of LUADs remains largely unknown.Here we find that ARID2 expression is decreased during the malignant progression of both human and mice LUADs.Using two Kras^(G12D)-based genetically engineered murine models,we demonstrate that ARID2 knockout significantly promotes lung cancer malignant progression and shortens overall survival.Consistently,ARID2 knockdown significantly promotes cell proliferation in human and mice lung cancer cells.Through integrative analyses of Ch IP-Seq and RNA-Seq data,we find that Hspa1 a is up-regulated by Arid2 loss.Knockdown of Hspa1 a specifically inhibits malignant progression of Arid2-deficient but not Arid2-wt lung cancers in both cell lines as well as animal models.Treatment with an HSPA1 A inhibitor could significantly inhibit the malignant progression of lung cancer with ARID2 deficiency.Together,our findings establish ARID2 as an important tumor suppressor in LUADs with novel mechanistic insights,and further identify HSPA1 A as a potential therapeutic target in ARID2-deficient LUADs. | Xue Wang Yuetong Wang Zhaoyuan Fang Hua Wang Jian Zhang Longfu Zhang Hsinyi Huang Zhonglin Jiang Yujuan Jin Xiangkun Han Shenda Hou Bin Zhou Feilong Meng Luonan Chen Kwok-Kin Wong Jinfeng Liu Zhiqi Zhang Xin Zhang Haiquan Chen Yihua Sun Liang Hu Hongbin Ji | 2021 | National Science Review2021，8，10： | 0 |
| 19 | A mesenchymal-like subpopulation in non-neuroendocrine SCLC contributes to metastasis显示文摘Small cell lung cancer(SCLC)is the most aggressive lung cancer with high heterogeneity.Mouse SCLC cells derived from the Rb1L/L/Trp53L/L(RP)autochthonous mouse model grew as adhesion or suspension in cell culture,and the adhesion cells are defined as non-neuroendocrine(non-NE)SCLC cells.Here,we uncover the heterogenous subpopulations within the non-NE cells and referred to them as mesenchymallike(Mes)and epithelial-like(Epi)SCLC cells.The Mes cells have increased capability to form colonies in soft agar and harbored stronger metastatic capability in vivo when compared with the Epi cells.Gene Set Enrichment Analysis reveals that the transforming growth factor(TGF)-βsignaling is enriched in the Mes cells.Importantly,inhibition of the TGF-βsignaling through ectopic expression of dominant-negative Tgfbr2(Tgfbr2-DN)or treatment with Tgfbr1 inhibitor SD-208 consistently abrogates tumor metastasis in nude mouse allograft assays.Moreover,genetic deletion of Tgfbr2 or Smad4,the key components of the TGF-βsignaling pathway,dramatically attenuates SCLC metastasis in the RP autochthonous mouse model.Collectively,our results uncover the high heterogeneity in non-NE SCLC cells and highlight an important role of TGF-βsignaling in promoting SCLC metastasis. | Yujuan Jin Tian Xiao Yan Feng Jinhua Yang Chenchen Guo Liang Hu Hongbin Ji | 2021 | Journal of Genetics and Genomics2021，48，7： | 0 |
| 20 | High-density genetic mapping identified a major locus for environmental sex expression in pumpkin(Cucurbita moschata Duch.)显示文摘Long-day length and high temperature inhibit sex expression in pumpkin(Cucurbita moschata Duch.),and therefore directly impact the production potential.In this study,female flowering patterns in photoperiod-insensitive(PPIS)and photoperiod-sensitive(PPS)germplasms differed significantly in a moderately long day and high temperature environment.However,both germplasms exhibited a similar response in short day with either low temperature or high temperature environment.Photoperiod sensitivity led to this difference in sex expression between the germplasms.For the traits of 1st female flowering node(FFFN)and number of female flowers(NFF),high-density linkage map construction and quantitative trait locus(QTL)mapping were performed using SLAF-seq technology and 162 F_(2) individuals generated from PPIS and PPS.In total,4655 SLAFs were selected and mapped on 20 linkage groups(LGs).The total map length was 2502.01 cM with an average interval distance of 0.75 cM.Major QTLs for both FFFN and NFF were detected on LG6 with intervals of 7.89 and 17.67 cM and PVE values of 30.5%and 22.9%,respectively.Further analyses of the major locus for FFFN revealed 73 protein-coding genes.Among them,4 were related to sex expression,photoperiod flowering,and hormone response.An InDel(insertion and deletion)marker partially correlated with FFFN of the F_(2) population was also developed.Our study identified the QTL for the sex expression response to environmental factors using the high-density linkage map.The identified candidate genes and markers will provide useful information about the molecular interaction between the environment and sex expression and for marker-assisted selection of pumpkin environment-insensitive resources. | Hafiz Muhammad Khalid Abbas Hexun Huang Tingquan Wu Rui Wang Hu Du Sen Lu Shudan Xue Chunpeng Yao Qingmin Jin Yujuan Zhong | 2022 | Horticultural Plant Journal2022，8，5： | 0 |
