12018 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 2018Science Bulletin2018,63,23:54

3The Human Microbiota in Health and Disease显示文摘Trillions of microbes have evolved with and continue to live on and within human beings. A variety of environmental factors can affect intestinal microbial imbalance, which has a close relationship with human health and disease. Here, we focus on the interactions between the human microbiota and the host in order to provide an overview of the microbial role in basic biological processes and in the development and progression of major human diseases such as infectious diseases, liver diseases, gastrointestinal cancers, metabolic diseases, respiratory diseases, mental or psychological diseases, and autoimmune diseases. We also review important advances in techniques associated with microbial research, such as DNA sequencing, metabonomics, and proteomics combined with computation-based bioinformatics.Current research on the human microbiota has become much more sophisticated and more comprehensive.Therefore, we propose that research should focus on the host-microbe interaction and on causeeffect mechanisms, which could pave the way to an understanding of the role of gut microbiota in health and disease, and provide new therapeutic targets and treatment approaches in clinical practice.Baohong Wang Mingfei Yao Longxian Lv Zongxin Ling Lanjuan Li 2017Engineering2017,3,1:24
4Polymorphisms in genes involved in folate metabolism as maternal risk factors for Down syndrome in China显示文摘Objective: To explore the relationship between genetic polymorphisms in methylenetetrahydrofolate reductase (MTHFR), methionine synthase reductase (MTRR), the central enzymes in folate metabolism that affects DNA methylation and synthesis, and the risk of Down syndrome in China. Methods: Genomic DNA was isolated from the peripheral lymphocytes of 64 mothers of children with Down syndrome and 70 age matched control subjects. Polymerase chain reaction and restriction fragment length polymorphism were used to examine the polymorphisms of MTHFR 677C→T, MTRR 66A→G and the relationship between these genotypes and the risk of Down syndrome was analyzed. Results: The results show that the MTHFR 677C→T polymorphism is more prevalent among mothers of children with Down syndrome than among control mothers, with an odds ratio of 3.78 (95% confidence interval (CI), 1.78~8.47). In addition, the homozygous MTRR 66A→G polymorphism was independently associated with a 5.2-fold increase in estimated risk (95% CI, 1.90~14.22). The combined presence of both polymorphisms was associated with a greater risk of Down syndrome than the presence of either alone, with an odds ratio of 6.0 (95% CI, 2.058~17.496). The two polymorphisms appear to act without a multiplicative interaction. Conclusion: MTHFR and MTRR gene mutation alleles are related to Down syndrome, and CT, TT and GG gene mutation types increase the risk of Down syndrome.Shao-shuai WANG Fu-yuan QIAO Ling FENG Juan-juan LV 2008Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2008,9,2:16
5Chromosomal level assembly and population sequencing of the Chinese tree shrew genome显示文摘Chinese tree shrews (Tupaia belangeri chinensis) have become an increasingly important experimental animal in biomedical research due to their close relationship to primates. An accurately sequenced and assembled genome is essential for understanding the genetic features and biology of this animal. In this study, we used long-read single-molecule sequencing and high-throughput chromosome conformation capture (Hi-C) technology to obtain a high-qualitychromosome-scale scaffolding of the Chinese tree shrew genome. The new reference genome (KIZ version 2: TS_2.0) resolved problems in presently available tree shrew genomes and enabled accurate identification of large and complex repeat regions, gene structures, and species-specific genomic structural variants. In addition, by sequencing the genomes of six Chinese tree shrew individuals, we produced a comprehensive map of 12.8 M single nucleotide polymorphisms and confirmed that the major histocompatibility complex (MHC) loci and immunoglobulin gene family exhibited high nucleotide diversity in the tree shrew genome. We updated the tree shrew genome database (TreeshrewDB v2.0: http://gffzzb70c77447da74c53hqwvpoxn6kfcb66kx.ffgz.tsg.suse.edu.cn) to include the genome annotation information and genetic variations. The new high-quality reference genome of the Chinese tree shrew and the updated TreeshrewDB will facilitate the use of this animal in many different fields of research.Yu Fan Mao-Sen Ye Jin-Yan Zhang Ling Xu Dan-Dan Yu Tian-Le Gu Yu-Lin Yao Jia-Qi Chen Long-Bao Lv Ping Zheng Dong-Dong Wu Guo-Jie Zhang Yong-Gang Yao 2019Zoological Research2019,40,6:15
6Breviscapine reduces neuronal injury caused by traumatic brain injury insult:partly associated with suppression of interleukin-6 expression显示文摘Breviscapine,extracted from the herb Erigeron breviscapus,is widely used for the treatment of cardiovascular diseases,cerebral infarct,and stroke,but its mechanism of action remains unclear.This study established a rat model of traumatic brain injury induced by controlled cortical impact,and injected 75 μg breviscapine via the right lateral ventricle.We found that breviscapine significantly improved neurobehavioral dysfunction at 6 and 9 days after injection.Meanwhile,interleukin-6 expression was markedly down-regulated following breviscapine treatment.Our results suggest that breviscapine is effective in promoting neurological behavior after traumatic brain injury and the underlying molecular mechanism may be associated with the suppression of interleukin-6.Ling Jiang Yue Hu Xiang He Qiang Lv Ting-hua Wang Qing-jie Xia 2017Neural Regeneration Research2017,12,1:14
7Recent progress and challenges in screening and characterization of UGT1A1 inhibitors显示文摘Uridine-diphosphate glucuronosyltransferase 1 A1(UGT1 A1) is an important conjugative enzyme in mammals that is responsible for the conjugation and detoxification of both endogenous and xenobiotic compounds. Strong inhibition of UGT1 A1 may trigger adverse drug/herb–drug interactions, or result in metabolic disorders of endobiotic metabolism. Therefore, both the US Food and Drug Administration(FDA)and the European Medicines Agency(EMA) have recommended assaying the inhibitory potential of drugs under development on the human UGT1 A1 prior to approval. This review focuses on the significance,progress and challenges in discovery and characterization of UGT1 A1 inhibitors. Recent advances in the development of UGT1 A1 probes and their application for screening UGT1 A1 inhibitors are summarized and discussed in this review for the first time. Furthermore, a long list of UGT1 A1 inhibitors, including information on their inhibition potency, inhibition mode, and affinity, has been prepared and analyzed. Challenges and future directions in this field are highlighted in the final section. The information and knowledge that are presented in this review provide guidance for rational use of drugs/herbs in order to avoid the occurrence of adverse effects via UGT1 A1 inhibition, as well as presenting methods for rapid screening and characterization of UGT1 A1 inhibitors and for facilitating investigations on UGT1 A1–ligand interactions.Xia Lv Yangliu Xia Moshe Finel Jingjing Wu Guangbo Ge Ling Yang 2019Acta Pharmaceutica Sinica B2019,9,2:14

11Subtyping Animal Influenza Virus with General Multiplex RT-PCR and Liquichip High Throughput (GMPLex)显示文摘This study developed a multiplex RT-PCR integrated with luminex technology to rapidly subtype simultaneously multiple influenza viruses. Primers and probes were designed to amplify NS and M genes of influenza A viruses HA gene of H1, H3, H5, H7, H9 subtypes, and NA gene of the N1 and N2 subtypes. Universal super primers were introduced to establish a multiplex RT-PCR (GM RT-PCR). It included three stages of RT-PCR amplification, and then the RT-PCR products were further tested by LiquiChip probe, combined to give an influenza virus (IV) rapid high throughput subtyping test, designated as GMPLex. The IV GMPLex rapid high throughput subtyping test presents the following features: high throughput, able to determine the subtypes of 9 target genes in H1, H3, H5, H7, H9, N1, and N2 subtypes of the influenza A virus at one time; rapid, completing the influenza subtyping within 6 hours; high specificity, ensured the specificity of the different subtypes by using two nested degenerate primers and one probe, no cross reaction occurring between the subtypes, no non-specific reactions with other pathogens and high sensitivity. When used separately to detect the product of single GM RT-PCR for single H5 or N1 gene, the GMPLex test showed a sensitivity of 10-5(= 280ELD50) forboth tests and the Luminex qualitative ratio results were 3.08 and 3.12, respectively. When used to detect the product of GM RT-PCR for H5N1 strain at the same time, both showed a sensitivity of 10-4(=2800 ELD50). The GMPLex rapid high throughput subtyping test can satisfy the needs of influenza rapid testing.Zhi-feng Qin Jie Sun Ti-kang Lu Shao-ling Zeng Qun-yi Hua Qing-yan Ling Shu-kun Chen Jian-qiang Lv Cai-hong Zhang Bing Cheng Zhou-xi Ruan Ying-zuo Bi Joseph J Giambrone Hong-zhuan Wu 2012Virologica Sinica2012,27,2:8
12Nanostructured lipid carrier based topical gel of Ganoderma Triterpenoids for frostbite treatment显示文摘The objective of this study was to prepare nanostructured lipid carrier(NLC)-based topical gel of Ganoderma Triterpenoids(GTs) and evaluate their effects on frostbite treatment. GT-NLCs was prepared by the high pressure homogenization method and then characterized by morphology and analyses of particle size, zeta potential, entrapment efficiency(EE), and drug loading(DL). The NLCs was suitably gelled for skin permeation studies in vitro and pharmacodynamic evaluation in vivo, compared with the GT emulgel. The GT-NLC remained within the colloidal range and was uniformly dispersed after suitably gelled by carbopol preparation. Transmission electron microscopy(TEM) study showed GT-NLCs was spherical in shape. The EE(%) and DL(%) could reach up to(81.84 ± 0.60)% and(2.13 ± 0.12)%, respectively. The result of X-ray diffractograms(XRD) showed that GTs were in an amorphous state in the NLC-gel. In vitro permeation studies through rat skin indicated that the amount of GTs permeated through skin of GT-NLCs after 24 h was higher than that of GT emulsion, and GT-NLCs increased the accumulative amounts of GTs in epidermis 7.76 times greater than GT emulsion. GT-NLC-gel was found to possess superior therapeutic effect for frostbite, compared with the GT emulgel. The NLC based topical gel of GTs could improve-their therapeutic effect for frostbite.SHEN Cheng-Ying DAI Ling SHEN Bao-De ZHOU Xu BAI Jin-Xia XU He LV Qing-Yuan HAN Jin YUAN Hai-Long 2015Chinese Journal of Natural Medicines2015,13,6:6
13Garlic-derived compound S-allylmercaptocysteine inhibits hepatocarcinogenesis through targeting LRP6/Wnt pathway显示文摘Whether and how garlic-derived S-allylmercaptocysteine(SAMC) inhibits hepatocellular carcinoma(HCC) is largely unknown. In the current study, the role of low-density lipoprotein receptor(LDLR)-related protein 6(LRP6) in HCC progression and the anti-HCC mechanism of SAMC was examined in clinical sample, cell model and xenograft/orthotopic mouse models. We demonstrated that SAMC inhibited cell proliferation and tumorigenesis, while induced apoptosis of human HCC cells without influencing normal hepatocytes. SAMC directly interacted with Wnt-pathway co-receptor LRP6 on the cell membrane. LRP6 was frequently over-expressed in the tumor tissue of human HCC patients(66.7% of 48 patients) and its overexpression only correlated with the over-expression of β-catenin, but not with age, gender, tumor size, stage and metastasis. Deficiency or over-expression of LRP6 in hepatoma cells could partly mimic or counteract the anti-tumor properties of SAMC, respectively. In vivo administration of SAMC significantly suppressed the growth of Huh-7 xenograft/orthotopic HCC tumor without causing undesirable side effects. In addition, stable down-regulation of LRP6 in Huh-7 facilitated the anti-HCC effects of SAMC. In conclusion, LRP6 can be a potential therapeutic target of HCC. SAMC is a promising specific anti-tumor agent for treating HCC subtypes with Wnt activation at the hepatoma cell surface.Jia Xiao Feiyue Xing Yingxia Liu Yi Lv Xiaogang Wang Ming-Tat Ling Hao Gao Songying Ouyang Min Yang Jiang Zhu Yu Xia Kwok-Fai So George L.Tipoe 2018Acta Pharmaceutica Sinica B2018,8,4:6
14Methodologies on estimating the energy requirements for maintenance and determining the net energy contents of feed ingredients in swine:a review of recent work显示文摘In the past two decades, a considerable amount of research has focused on the determination of the digestible(DE) and metabolizable energy(ME) contents of feed ingredients fed to swine. Compared with the DE and ME systems, the net energy(NE) system is assumed to be the most accurate estimate of the energy actually available to the animal. However, published data pertaining to the measured NE content of ingredients fed to growing pigs are limited. Therefore, the Feed Data Group at the Ministry of Agricultural Feed Industry Centre(MAFIC) located at China Agricultural University has evaluated the NE content of many ingredients using indirect calorimetry. The present review summarizes the NE research works conducted at MAFIC and compares these results with those from other research groups on methodological aspect. These research projects mainly focus on estimating the energy requirements for maintenance and its impact on the determination, prediction, and validation of the NE content of several ingredients fed to swine. The estimation of maintenance energy is affected by methodology, growth stage,and previous feeding level. The fasting heat production method and the curvilinear regression method were used in MAFIC to estimate the NE requirement for maintenance. The NE contents of different feedstuffs were determined using indirect calorimetry through standard experimental procedure in MAFIC. Previously generated NE equations can also be used to predict NE in situations where calorimeters are not available. Although popular, the caloric efficiency is not a generally accepted method to validate the energy content of individual feedstuffs. In the future,more accurate and dynamic NE prediction equations aiming at specific ingredients should be established, and more practical validation approaches need to be developed.Zhongchao Li Hu Liu akui Li Zhiqian Lv Ling Liu Changhua Lai Junjun Wang Fenglai Wang Defa Li Shuai Zhang 2018Journal of Animal Science and Biotechnology2018,9,3:6
15Polymorphism-Dependent Dynamic Ultralong Organic Phosphorescence显示文摘Developing ultralong organic phosphorescence(UOP)materials with smart response to external stimuli is of great interest in photonics applications,whereas the manipulation of molecular stacking on tuning such dynamic UOP is still a formidable challenge.Herein,we have reported two polymorphs with distinct photoactivated dynamic UOP behavior based on a pyridine derivative for the first time.Our experiment revealed that the dynamic UOP behavior including photoactivation and deactivation feature is highly dependent on irradiation intensity and environmental atmosphere.Additionally,given the unique dynamic UOP feature,these phosphors have been successfully applied to phosphorescence-dependent molecular logic gate and timing data storage.This result not only paves a way to design smart functional materials but also expands the scope of the applications on organic phosphorescence materials.Mingxing Gu Huifang Shi Kun Ling Anqi Lv Kaiwei Huang Manjeet Singh He Wang Long Gu Wei Yao Zhongfu An Huili Ma Wei Huang 2020Research2020,,1:5
16Comprehensive annotation of the Chinese tree shrew genome by large-scale RNA sequencing and long-read isoform sequencing显示文摘The Chinese tree shrew(Tupaia belangeri chinensis)is emerging as an important experimental animal in multiple fields of biomedical research.Comprehensive reference genome annotation for both mRNA and long non-coding RNA(lncRNA)is crucial for developing animal models using this species.In the current study,we collected a total of 234 high-quality RNA sequencing(RNA-seq)datasets and two long-read isoform sequencing(ISO-seq)datasets and improved the annotation of our previously assembled high-quality chromosomelevel tree shrew genome.We obtained a total of 3514 newly annotated coding genes and 50576 lncRNA genes.We also characterized the tissuespecific expression patterns and alternative splicing patterns of mRNAs and lncRNAs and mapped the orthologous relationships among 11 mammalian species using the current annotated genome.We identified 144 tree shrew-specific gene families,including interleukin 6(IL6)and STT3 oligosaccharyltransferase complex catalytic subunit B(STT3B),which underwent significant changes in size.Comparison of the overall expression patterns in tissues and pathways across four species(human,rhesus monkey,tree shrew,and mouse)indicated that tree shrews are more similar to primates than to mice at the tissue-transcriptome level.Notably,the newly annotated purine rich element binding protein A(PURA)gene and the STT3B gene family showed dysregulation upon viral infection.The updated version of the tree shrew genome annotation(KIZ version 3:TS_3.0)is available at http://gffzzb70c77447da74c53hqwvpoxn6kfcb66kx.ffgz.tsg.suse.edu.cn and provides an essential reference for basic and biomedical studies using tree shrew animal models.Mao-Sen Ye Jin-Yan Zhang Dan-Dan Yu Min Xu Ling Xu Long-Bao Lv Qi-Yun Zhu Yu Fan Yong-Gang Yao 2021Zoological Research2021,42,6:5
17Multimodal therapy strategies based on hydrogels for the repair of spinal cord injury显示文摘Spinal cord injury(SCI)is a serious traumatic disease of the central nervous system,which can give rise to the loss of motor and sensory function.Due to its complex pathological mechanism,the treatment of this disease still faces a huge challenge.Hydrogels with good biocompatibility and biodegradability can well imitate the extracellular matrix in the microenvironment of spinal cord.Hydrogels have been regarded as promising SCI repair material in recent years and continuous studies have confirmed that hydrogel-based therapy can effectively eliminate inflammation and promote spinal cord repair and regeneration to improve SCI.In this review,hydrogel-based multimodal therapeutic strategies to repair SCI are provided,and a combination of hydrogel scaffolds and other therapeutic modalities are discussed,with particular emphasis on the repair mechanism of SCI.Yan Wang Hong-Qian Lv Xuan Chao Wen-Xin Xu Yun Liu Gui-Xia Ling Peng Zhang 2022Military Medical Research2022,9,5:5

19Sheng-jiang powder ameliorates obesity-induced pancreatic inflammatory injury via stimulating activation of the AMPK signalling pathway in rats显示文摘AIM To investigate the mechanisms by which Sheng-jiang powder(SJP) ameliorates obesity-induced pancreatic inflammatory injury.METHODS Sprague-Dawley rats were randomized into three groups: normal group(NG), obese group(HLG), or SJP treatment group(HSG). Obesity was induced by feeding a high-fat diet in the HLG and HSG, while the NG received standard chow. Rats were euthanized after 12 wk, and blood and pancreatic tissues were collected for histopathological analyses. Nuclear factor kappa-light-chain-enhancer of activated B cells(NF-κB) and transforming growth factor beta(TGF-β) expression, serum triglyceride and adiponectin levels, and apoptosis in pancreatic acinar cells were assessed. A high-fat AR42 J acinar cell injury model was established using very low-density lipoprotein(VLDL). AR42 J acinar cell culture supernatant, treated with different interventions, was applied to seven groups of pancreatic stellate cells(PSCs). The proliferation of PSCs and the expression of fibronectin and type I collagenase were assessed.RESULTS Compared with the NG, we found higher pathological scores for pancreatic tissues, lower serum adiponectin levels, higher expression levels of NF-κB in pancreatic tissues and TGF-β in pancreatic inflammatory cells, and increased apoptosis among pancreatic acinar cells for the HLG(P < 0.05). Compared with the HLG, we found reduced body weight, Lee's index scores, serum triglyceride levels, and pathological scores for pancreatic tissues; higher serum adiponectin levels; and lower expression levels of NF-κB, in pancreatic tissue and TGF-β in pancreatic inflammatory cells for the HSG(P < 0.05). The in vitro studies showed enhanced PSC activation and increased expression levels of fibronectin and type I collagenase after SJP treatment. An adenosine 5‘-monophosphate-activated protein kinase(AMPK) inhibitor inhibited PSC activation.CONCLUSION SJP may ameliorate obesity-induced pancreatic inflammatory injury in rats by regulating key molecules of the adiponectin-AMPK signalling pathway.Yi-Fan Miao Juan Li Yu-Mei Zhang Lv Zhu Huan Chen Ling Yuan Jing Hu Xiao-Lin Yi Qiu-Ting Wu Mei-Hua Wan Wen-Fu Tang 2018World Journal of Gastroenterology2018,24,39:4
