| 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 | FGF1^(△HBS) prevents diabetic cardiomyopathy by maintaining mitochondrial homeostasis and reducing oxidative stress via AMPK/Nur77 suppression显示文摘As a classically known mitogen,fibroblast growth factor 1(FGF1)has been found to exert other pleiotropic functions such as metabolic regulation and myocardial protection.Here,we show that serum levels of FGF1 were decreased and positively correlated with fraction shortening in diabetic cardiomyopathy(DCM)patients,indicating that FGF1 is a potential therapeutic target for DCM.We found that treatment with a FGF1 variant(FGF1^(△HBS))with reduced proliferative potency prevented diabetes-induced cardiac injury and remodeling and restored cardiac function.RNA-Seq results obtained from the cardiac tissues of db/db mice showed significant increase in the expression levels of anti-oxidative genes and decrease of Nur77 by FGF1AHBS treatment.Both in vivo and in vitro studies indicate that FGF1^(△HBS) exerted these beneficial effects by markedly reducing mitochondrial fragmentation,reactive oxygen species(ROS)generation and cytochrome c leakage and enhancing mitochondrial respiration rate and β-oxidation in a 5;AMP-activated protein kinase(AMPK)/Nur77-dependent manner,all of which were not observed in the AMPK null mice.The favorable metabolic activity and reduced proliferative properties of FGF1^(△HBS) testify to its promising potential for use in the treatment of DCM and other metabolic disorders. | Dezhong Wang Yuan Yin Shuyi Wang Tianyang Zhao Fanghua Gong Yushuo Zhao Beibei Wang Yuli Huang Zizhao Cheng Guanghui Zhu Zengshou Wang Yang Wang Jun Ren Guang Liang Xiaokun Li Zhifeng Huang | 2021 | Signal Transduction and Targeted Therapy2021，6，4： | 6 |
| 4 | Internal heat transfer coefficients in microporous media with rarefaction effects显示文摘The internal heat transfer of different gases in microporous media was investigated experimentally and numerically.The experimental test section had a sintered bronze porous media with average particle diameters from 11 μm to 225 μm.The Knudsen numbers at the average inlet and outlet pressures of each test section varied from 0.0006 to 0.13 with porosities from 0.16 to 0.38.The particle-to-fluid heat transfer coefficients of air,CO 2 and helium in the microporous media were determined experimentally.The results show that the Nusselt numbers for the internal heat transfer in the microporous media decrease with decreasing the particle diameter,d p,and increasing Knudsen number for the same Reynolds number.For Kn>0.01,the rarefaction affects the internal heat transfer in the microporous media.A Nusselt number correlation was developed that includes the influence of rarefaction.The computational fluid dynamics(CFD) numerical simulation was carried out to do the pore scale simulation of internal heat transfer in the microporous media considering the rarefaction effect.Pore scale three-dimensional numerical simulations were also used to predict the particle-to-fluid heat transfer coefficients.The numerical results without slip-flow and temperature jump effects for Kn<0.01 corresponded well with the experimental data.The numerical results with slip-flow and temperature jump effects for 0.01 | XU RuiNa HUANG YuLi JIANG PeiXue WANG BuXuan | 2012 | Science China(Technological Sciences)2012，55，10： | 4 |

| 6 | Systematic study on the mechanical and electric behaviors of the nonbuckling interconnect design of stretchable electronics显示文摘Recently, we developed a nonbuckling interconnect design that provides an effective approach to simultaneously achieving high elastic stretchability, easiness for encapsulation, and high electric performance for stretchable electronics. This paper aims to systematically study its mechanical and electric behaviors, including comparisons of the nonbuckling and buckling interconnect designs on stretchability, effects of the thickness on electric performance, and modeling and experimental investigations on the finite deformation mechanics. It is found that the results on stretchability depend on the layouts. Long straight segments and small arc radii for nonbuckling interconnects yield an enhancement of stretchability, which is much better than that of buckling designs. On the other hand, shorter straight segments or thicker interconnects are better to lower the resistances of interconnects.Therefore, optimization of the designs needs to balance the requirements of both the mechanical and electric performances. The finite deformation of interconnects during stretching is analyzed. The established analytic model is well validated by both the finite element modeling and experimental investigations. This work is key for providing the design guidelines for nonbucklingbased stretchable electronics. | Hao Liu RiYe Xue JianQiao Hu XueCheng Ping HuaPing Wu MingQi Huang Han Zhang Xu Guo Rui Li YuLi Chen YeWang Su | 2018 | Science China(Physics,Mechanics & Astronomy)2018，61，11： | 3 |
| 7 | Application of immune checkpoint targets in the anti-tumor novel drugs and traditional Chinese medicine development显示文摘Immune checkpoints are the crucial regulators of immune system and play essential roles in maintaining self-tolerance,preventing autoimmune responses,and minimizing tissue damage by regulating the duration and intensity of the immune response.Furthermore,immune checkpoints are usually overexpressed in cancer cells or noninvasive cells in tumor tissues and are capable of suppressing the antitumor response.Based on substantial physiological analyses as well as preclinical and clinical studies,checkpoint molecules have been evaluated as potential therapeutic targets for the treatment of multiple types of cancers.In the last few years,extensive evidence has supported the immunoregulatory effects of traditional Chinese medicines(TCMs).The main advantage of TCMs and natural medicine is that they usually contain multiple active components,which can act on multiple targets at the same time,resulting in additive or synergistic effects.The strong immune regulation function of traditional Chinese medicine on immune checkpoints has also been of great interest.For example,Astragalus membranaceus polysaccharides can induce anti-PD-1 antibody responses in animals,and these antibodies can overcome the exhaustion of immune cells under tumor immune evasion.Furthermore,many other TCM molecules could also be novel and effective drug candidates for the treatment of cancers.Therefore,it is essential to assess the application of immune checkpoints in the development of new drugs and TCMs.In this review,we focus on research progress in the field of immune checkpoints based on three topics:(1)immune checkpoint targets and pathways,(2)development of novel immune checkpoint-based drugs,and(3)application of immune checkpoints in the development of TCMs. | Yuli Wang Xingyan Zhang Yuyan Wang Wenjing Zhao Huling Li Lixing Zhang Xinping Li Tiejun Zhang Hongbing Zhang He Huang Changxiao Liu | 2021 | Acta Pharmaceutica Sinica B2021，11，10： | 3 |

| 9 | Problem-Based Cybersecurity Lab with Knowledge Graph as Guidance显示文摘Lecture-based teaching paired with laboratory-based exercises is mostly used in cybersecurity instruction.However,it focuses more on theories and models but fails to provide learners with practical problem-solving skills and opportunities to explore real-world cybersecurity challenges.Problem-based learning(PBL)has been identified as an efficient pedagogy for many disciplines,especially engineering education.It provides learners with real-world complex problem scenarios,which encourages learners to collaborate with classmates,ask questions,and develop a deeper understanding of the concepts while solving realworld cybersecurity problems.This article describes the application of the PBL methodology to enhance professional trainingbased cybersecurity education.The authors developed an online laboratory environment to apply PBL with Knowledge Graph(KG)-based guidance for hands-on labs in cybersecurity training.Learners are provided access to a virtual lab environment with KG guidance to simulated real-life cybersecurity scenarios.Thus,they are forced to think independently and apply their knowledge to create cyber attacks and defend approaches to solve problems provided to them in each lab.Our experimental study shows that learners tend to gain more enhanced learning outcomes by leveraging PBL with KG guidance,become more aware of cybersecurity and relevant concepts,and express interest in keep learning of cybersecurity using our system. | Yuli Deng Zhen Zeng Kritshekhar Jha Dijiang Huang | 2022 | Journal of Artificial Intelligence and Technology2022，2，2： | 1 |
| 10 | An international Delphi consensus statement on metabolic dysfunction-associated fatty liver disease and risk of chronic kidney disease显示文摘Background:With the rising global prevalence of fatty liver disease related to metabolic dysfunction,the association of this common liver condition with chronic kidney disease(CKD)has become increasingly evident.In 2020,the more inclusive term metabolic dysfunction-associated fatty liver disease(MAFLD)was proposed to replace the term non-alcoholic fatty liver disease(NAFLD).The observed association between MAFLD and CKD and our understanding that CKD can be a consequence of underlying metabolic dysfunction support the notion that individuals with MAFLD are at higher risk of having and developing CKD compared with those without MAFLD.However,to date,there is no appropriate guidance on CKD in individuals with MAFLD.Furthermore,there has been little attention paid to the link between MAFLD and CKD in the Nephrology community.Methods and Results:Using a Delphi-based approach,a multidisciplinary panel of 50 international experts from 26 countries reached a consensus on some of the open research questions regarding the link between MAFLD and CKD.Conclusions:This Delphi-based consensus statement provided guidance on the epidemiology,mechanisms,management and treatment of MAFLD and CKD,as well as the relationship between the severity of MAFLD and risk of CKD,which establish a framework for the early prevention and management of these two common and interconnected diseases. | Dan-Qin Sun Giovanni Targher Christopher D.Byrne David C.Wheeler Vincent Wai-Sun Wong Jian-Gao Fan Herbert Tilg Wei-Jie Yuan Christoph Wanner Xin Gao Michelle T.Long Mehmet Kanbay Mindie H.Nguyen Sankar D.Navaneethan Yusuf Yilmaz Yuli Huang Rino A.Gani Pierluigi Marzuillo Jérôme Boursier Huijie Zhang Chan-Young Jung Jin Chai Luca Valenti George Papatheodoridis Giovanni Musso Yu-Jun Wong Mohamed El-Kassas Nahum Méndez-Sánchez Silvia Sookoian Michael Pavlides Ajay Duseja Adriaan G.Holleboom Junping Shi Wah-Kheong Chan Yasser Fouad Junwei Yang Sombat Treeprasertsuk Helena Cortez-Pinto Masahide Hamaguchi Manuel Romero-Gomez Mamun Al Mahtab Ponsiano Ocama Atsushi Nakajima Chunsun Dai Mohammed Eslam Lai Wei Jacob George Ming-Hua Zheng | 2023 | Hepatobiliary Surgery and Nutrition2023，12，3： | 1 |

| 13 | Milk-derived exosomes exhibit versatile effects for improved oral drug delivery显示文摘As endogenous courier vesicles,exosomes play crucial roles in macromolecule transmission and intercellular communication.Therefore,exosomes have drawn increasing attention as biomimetic drug-delivery vehicles over the past few years.However,few studies have investigated the encapsulation of peptide/protein drugs into exosomes for oral administration.Additionally,the mechanisms underlying their biomimetic properties as oral delivery vehicles remain unknown.Herein,insulin-loaded milk-derived exosomes(EXO@INS)were fabricated and the in vivo hypoglycemic effect was investigated on type I diabetic rats.Surprisingly,EXO@INS(50 and 30 IU/kg)elicited a more superior and more sustained hypoglycemic effect compared with that obtained with subcutaneously injected insulin.Further mechanism studies indicated that the origin of excellent oral-performance of milk-derived exosomes combined active multi-targeting uptake,pH adaptation during gastrointestinal transit,nutrient assimilation related ERK1/2 and p38 MAPK signal pathway activation and intestinal mucus penetration.This study provides the first demonstration that multifunctional milk-derived exosomes offer solutions to many of the challenges arising from oral drug delivery and thus provide new insights into developing naturally-equipped nanovehicles for oral drug administration. | Lei Wu Lingling Wang Xi Liu Yuli Bai Ruinan Wu Xiang Li Yutong Mao Ling Zhang Yongxiang Zheng Tao Gong Zhirong Zhang Yuan Huang | 2022 | Acta Pharmaceutica Sinica B2022，12，4： | 1 |
| 14 | Evaluation of Tear Malate Dehydrogenase 2 in Mild Dry Eye Disease显示文摘Purpose: To evaluate the effect of tear malate dehydrogenase2 on monitoring ocular surface injury in mild dry eye(DE)disease.Methods: A total of 15 DE patients(30 eyes) with mild subjective symptoms but no ocular surface fluorescein staining signs were enrolled in this study.(DE group)..The control group was 15 healthy age- and sex-matched volunteers(30eyes)..All subjects were asked to fill out a DE symptoms questionnaire and take different tests including tear MDH and MDH2 activities evaluation,..tear breakup time.(TBUT),Schirmer I,.and slit-lamp examination of the ocular surface.We investigated different changes in tear MDH and MDH2 activities in the DE group and control group,.discussed the association between tear MDH2 activity and DE symptoms, and the relationship between tear MDH2 activity and diagnostic tests(Schirmer I and TBUT). We also analyzed the changes in tear MDH2 activities after the treatment with artificial tears.Results:.Tear MDH activities in the DE group and control group were 288 ±102 U / L and 259 ±112 U / L,.respectively,and this difference was not statistically significant(P >0.05).The tear MDH2 activities in DE group were significantly increased compared with control group. Tear MDH2 was significantly and negatively correlated with the Schirmer's value(r=-0.733,P<0.01) and the TBUT value(r=-0.841,P<0.01)..MDH2 also had a significant positive correlation with soreness symptoms(r=0.687, P < 0.01). Treatment with artificial tears relieved or eliminated all discomfort symptoms, together with a considerable decrease in MDH2 activities(P <0.01),.but no significant changes in the Schirmer and the TBUT tests were observed.Conclusion: Tear MDH2 activity can indicate ocular surfaceinjury in mild DE patients and may be used to monitor the response to therapy. | Qing Guo Houbin Huang Yuli Pi Hancheng Zhang | 2014 | Eye Science2014，29，4： | 1 |

| 17 | Deep learning quantified mucus-tumor ratio predicting survival of patients with colorectal cancer using whole-slide images显示文摘Background:In colorectal cancer(CRC),mucinous adenocarcinoma differs from other adenocarcinomas in gene-phenotype,morphology,and prognosis.However,mucinous components are present in a large number of adenocarcinomas,and the prognostic value of mucus proportion has not been investigated.Artificial intelligence provides a way to quantify mucus proportion on whole-slide images(WSIs)accurately.We aimed to quantify mucus proportion by deep learning and further investigate its prognostic value in two CRC patient cohorts.Methods:Deep learning was used to segment WSIs stained with hematoxylin and eosin.Mucus-tumor ratio(MTR)was defined as the proportion of mucinous component in the tumor area.A training cohort(N=419)and a validation cohort(N=315)were used to evaluate the prognostic value of MTR.Survival analysis was performed using the Cox proportional hazard model.Result:Patients were stratified tomucus-low andmucus-high groups,with 24.1%as the threshold.In the training cohort,patients with mucus-high had unfavorable outcomes(hazard ratio for high vs.low 1.88,95%confidence interval 1.18–2.99,P=0.008),with 5-year overall survival rates of 54.8%and 73.7%in mucus-high and mucus-lowgroups,respectively.The resultswere confirmed in the validation cohort(2.09,1.21–3.60,0.008;62.8%vs.79.8%).The prognostic value of MTR was maintained in multivariate analysis for both cohorts.Conclusion:The deep learning quantified MTR was an independent prognostic factor in CRC.With the advantages of advanced efficiency and high consistency,our method is suitable for clinical application and promotes precision medicine development. | Ke Zhao Lin Wu Yanqi Huang Su Yao Zeyan Xu Huan Lin Huihui Wang Yanting Liang Yao Xu Xin Chen Minning Zhao Jiaming Peng Yuli Huang Changhong Liang Zhenhui Li Yong Li Zaiyi Liu | 2021 | Precision Clinical Medicine2021，4，1： | 0 |
| 18 | Atomic-scale characterization of two-dimensional magnets and their heterostructures显示文摘The realization of long-range magnetic ordering in two-dimensional(2D)van der Waals systems significantly expands the scope of the 2D family as well as their possible spin-related phenomena and device applications.The atomically thin nature of 2D materials makes their magnetically ordered states sensitive to local environments,and this necessitates advanced characterization at the atomic scale.Here,we briefly review several representative 2D magnetic systems,namely,iron chalcogenides,chromium chalcogenides,chromium trihalides,and their het-erostructures.With powerful scanning-probe microscopy,atomically resolved characterization of their crystalline configurations,electronic structures,and magnetization distributions has been achieved,and novel phenomena such as giant tunneling magnetoresistance and topological superconductivity have been observed.Finally,we discuss the challenges and new perspectives in this flourishing field. | Yuli Huang Mingyue Sun Yihe Wang Andrew Thye Shen Wee Wei Chen | 2023 | ChemPhysMater2023，2，4： | 0 |
| 19 | An efficient and safe strategy for germ cell-specific automatic excision of foreign DNA in F1 hybrid transgenic silkworms显示文摘The safety of transgenic technology is a major obstacle in the popularization and use of transgenic silkworms and their products.In sericulture,only the first filial generation(F1)hybrid eggs produced by cross-breeding Japanese and Chinese original strains are usually used for the large-scale breeding of silkworms,but this may result in uncontrolled transgene dispersal during the popularization and application of the F1 hybrid transgenic eggs.To address this issue,we developed a safe and efficient strategy using the GAL4/Upstream activating sequence(UAS)system,the FLP/flippase recognition target(FRT)system,and the gonad-specific expression gene promoters(RSHP1p and Nanosp)for the germ cell-specific automatic excision of foreign DNA in the F1 hybrid transgenic silkworms.We established 2 types of activator strains,R1p::GAL4-Gr and Nsp::GAL4-Gr,containing the testis-specific GAL4 gene expression cassettes driven by RSHP1p or Nanosp,respectively,and 1 type of effector strain,UAS::FLP-Rg,containing the UAS-linked FLP gene expression cassette.The FLP recombinase-mediated sperm-specific complete excision of FRT-flanked target DNA in the F1 double-transgenic silkworms resulting from the hybridization of R1p::GAL4-Gr and UAS::FLP-Rg was 100%,whereas the complete excision efficiency resulting from the hybridization of Nsp::GAL4-Gr and UAS::FLP-Rg ranged from 13.73%to 80.3%.Additionally,we identified a gene,sw11114,that is expressed in both testis and ovary of Bombyx mori,and can be used to establish novel gonad-specific expression systems in transgenic silkworms.This strategy has the potential to fundamentally solve the safety issue in the production of F1 transgenic silkworm eggs and provides an important reference for the safety of transgenic technology in other insect species. | Dingpei Long Rongpeng Liu Yang Huang Anyao Fu Yuli Zhang Zhanzhang Hao Qiang Li Hanfu Xu Zhonghuai Xiang Aichun Zhao | 2024 | Insect Science2024，31，1： | 0 |
| 20 | Alterations in nutrient digestibility and performance of heat-stressed dairy cows by dietary L-theanine supplementation显示文摘The purpose of this study was to investigate the effects of dietary L-theanine supplementation on apparent nutrient digestibility,milk yield,milk composition,and blood biochemical indices of dairy cows under heat stress.Thirty Chinese Holstein cows(19.84±2.42 kg milk/d,192.36±40.77 d in milk and2±0.93 parities)were divided into 3 groups of 10 animals each.The control group was fed a basal total mixed ration(TMR)diet,while treatment 1(LTA16)and treatment 2(LTA32)groups were fed a basal TMR diet supplemented with L-theanine at 16 and 32 g/cow per day,respectively.The results showed that feeding the dairy cows with LTA16 treatment decreased(P<0.05)their rectal temperature,whereas feeding with LTA32 treatment decreased(P<0.05)their rumen fluid ammonia nitrogen content.In comparison to the control group,the supplementation of L-theanine had no significant effect(P>0.05)on the dry matter intake,nutrient digestibility,total volatile fatty acid(TVFA)concentration and molar proportion of volatile fatty acid,milk yield,milk composition,feed efficiency and antioxidant capacity of the dairy cows.The triglyceride(TG)content of the LTA32 group was significantly greater(P=0.014)than that of the control group.With the increase in L-theanine dosage,the serum cholesterol(CHOL)content significantly increased(P=0.013).The serum albumin(ALB;P=0.067),low-density lipoprotein cholesterol(LDL-C;P=0.053),and high-density lipoprotein cholesterol(HDL-C;P=0.067)contents showed an upward trend as L-theanine dosage increased.Ultimately,the results of this study show that supplementing dairy cow diet with L-theanine could decrease dairy cow rectal temperature,affect lipid metabolism,and potentially relieve the heat stress of dairy cows to some extent. | Lingyuan Yang Lingmei Zhang Peihua Zhang Yuli Zhou Xingguo Huang Qiongxian Yan Zhiliang Tan Shaoxun Tang Fachun Wan | 2022 | Animal Nutrition2022，，4： | 0 |
