1Spatial Properties of Mismatch Negativity in Patients with Disorders of Consciousness显示文摘In recent decades, event-related potentials have been used for the clinical electrophysiological assessment of patients with disorders of consciousness(DOCs). In this paper, an oddball paradigm with two types of frequencydeviant stimulus(standard stimuli were pure tones of 1000 Hz; small deviant stimuli were pure tones of 1050 Hz; large deviant stimuli were pure tones of 1200 Hz) was applied to elicit mismatch negativity(MMN) in 30 patients with DOCs diagnosed using the JFK Coma Recovery ScaleRevised(CRS-R). The results showed that the peak amplitudes of MMN elicited by both large and small deviant stimuli were significantly different from baseline.In terms of the spatial properties of MMN, a significant interaction effect between conditions(small and large deviant stimuli) and electrode nodes was centered at the frontocentral area. Furthermore, correlation coefficients were calculated between MMN amplitudes and CRS-R scores for each electrode among all participants to generate topographic maps. Meanwhile, a significant negative correlation between the MMN amplitudes elicited by large deviant stimuli and the CRS-R scores was also found at the frontocentral area. In consequence, our results combine the above spatial properties of MMN in patients with DOCs,and provide a more precise location(frontocentral area) at which to evaluate the correlation between clinical electrophysiological assessment and the level of consciousness.Xiaoyu Wang Rao Fu Xiaoyu Xia Xueling Chen Han Wu Nicole LANDi Ken Pugh Jianghong He Fengyu Cong 2018Neuroscience Bulletin2018,34,4:9
2Prioritizing natural-selection signals from the deep-sequencing genomic data suggests multi-variant adaptation in Tibetan highlanders显示文摘Human genetic adaptation to high altitudes(>2500 m)has been extensively studied over the last few years,but few functional adaptive genetic variants have been identified,largely owing to the lack of deep-genome sequencing data available to previous studies.Here,w e build a list of putative adaptive variants,including 63 missense,7 loss-of-function;1,298 evolutionarily conserved variants and 509 expression quantitative traits loci.Notably,the top signal of selection is located in TMEM 247,a transmembrane protein-coding gene.The Tibetan version of TMEM 247 harbors one high-frequency(76.3%)missense variant,rsl 16983452(c.248C>T;p.Ala83Val);with the T allele derived from archaic ancestry and carried by>94%of Tibetans but absent or in low frequencies(<3%)in non-Tibetan populations.The rsl 16983452-T is strongly and positively correlated with altitude and significantly associated with reduced hemoglobin concentration(p=5.78×10^-5),red blood cell count(p=5.72×10^-7)and hematocrit(p=2.57×10^-6).In particular,TMEM247-rs 116983452 shows greater effect size and better predicts the phenotypic outcome than any E P A S1 variants in association with adaptive traits in Tibetans.Modeling the interaction between TM£M247-rsl 16983452 and EPAS1 variants indicates weak but statistically significant epistatic effects.Our results support that multiple variants may jointly deliver the fitness of the Tibetans on the plateau,where a complex model is needed to elucidate the adaptive evolution mechanism.Lian Deng Chao Zhang Kai Yuan Yang Gao Yuwen Pan Xueling Ge Yaoxi He Yuan Yuan Yan Lu Xiaoxi Zhang Hao Chen Haiyi Lou Xiaoji Wang Dongsheng Lu Jiaojiao Liu Lei Tian Qidi Feng Asifullah Khan Yajun Yang Zi-Bing Jin Jian Yang Fan Lu Jia Qu Longli Kang Bing Su Shuhua Xu 2019National Science Review2019,6,6:9
3Effects of Sini San used alone and in combination with fluoxetine on central and peripheral 5-HT levels in a rat model of depression显示文摘OBJECTIVE: To investigate the effects of Sini San and fluoxetine on the levels of central and peripheral 5-HT in a rat model of depression, and provide new insight into the treatment of depression with integrated Chinese-Western Medicine.METHODS: A rat model of depression was established by chronic mild stress(CMS). Model rats received either Sini San, fluoxetine, a combination of the two drugs, or no drug treatment. Healthy naive rats were used as controls. Open field and sucrose preference tests were used to assess depression-like behavior. ELISA and immunohistochemistry were used to determine central and peripheral levels of 5-HT.RESULTS: In the group with no drug treatment,central 5-HT expression decreased while peripheral5-HT concentrations increased as CMS continued.Four weeks after CMS, Sini San alone was less effective in reducing depression-like behavior than fluoxetine alone or in combination with Sini San,but combined use was more effective than fluoxetine alone. Eight weeks after CMS, Sini San alone or in combination with fluoxetine was more effective in reducing depression-like behavior than fluoxetine alone. Furthermore Sini San and fluoxetine used alone or in combination notably increased central 5-HT expression and decreased peripheral 5-HT levels in the rat model.CONCLUSION:The results of the present study indicate that there is a synergistic action between the two medicines in the treatment of depression. Sini San exhibited a relatively long lag before its effects were observed; however, by eight weeks the Traditional Chinese Medicine appeared at least as effective as fluoxetine. We suggest that Sini San can replace fluoxetine in the later stages of depression treatment to minimize side effects observed with long-term fluoxetine administration.Yubo Li Yuxiu Sun Xueling Ma Xiaoxing Xue Wenting Zhang Zhiqian Wu Yulin Ouyang Jianxin Chen Weiming Wang Shuzhen Guo Wei Wang 2013Journal of Traditional Chinese Medicine2013,33,5:6
4The Relationship Between the Gut Microbiome and Neurodegen-erative Diseases显示文摘Many recent studies have shown that the gut microbiome plays important roles in human physiology and pathology.Also,microbiome-based therapies have been used to improve health status and treat diseases.In addition,aging and neurodegenerative diseases,including Alzheimer’s disease and Parkinson’s disease,have become topics of intense interest in biomedical research.Several researchers have explored the links between these topics to study the potential pathogenic or therapeutic effects of intestinal microbiota in disease.But the exact relationship between neurodegenerative diseases and gut microbiota remains unclear.As technology advances,new techniques for studying the microbiome will be developed and refined,and the relationship between diseases and gut microbiota will be revealed.This article summarizes the known interactions between the gut microbiome and neurodegenerative diseases,highlighting assay techniques for the gut microbiome,and we also discuss the potential therapeutic role of microbiome-based therapies in diseases.Xueling Zhu Bo Li Pengcheng Lou Tingting Dai Yang Chen Aoxiang Zhuge Yin Yuan Lanjuan Li 2021Neuroscience Bulletin2021,37,10:6
5Activin A maintains cerebral cortex neuronal survival and increases voltage-gated Na^+ neuronal current显示文摘Activin A,which was first described in 1986,has been shown to maintain hippocampal neuronal survival.Activin A increases intracellular free Ca2+ via L-type Ca2+ channels.Our previous study showed that activin A promotes neurite growth of dorsal root ganglia in embryonic chickens and inhibits nitric oxide secretion.The present study demonstrated for the first time that activin A could maintain cerebral cortex neuronal survival in vitro for a long period,and that activin A was shown to increase voltage-gated Na+ current(INa) in Neuro-2a cells,which was recorded by patch clamp technique.The present study revealed a novel mechanism for activin A,as well as the influence of activin A on neurons by regulating expressions of vasoactive intestine peptide and inducible nitric oxide synthase.Jingyan Ge Yinan Wang Haiyan Liu Fangfang Chen Xueling Cui Zhonghui Liu 2010Neural Regeneration Research2010,5,19:4
618beta-glycyrrhetinic acid induces ROS-mediated apoptosis to ameliorate hepatic fibrosis by targeting PRDX1/2 in activated HSCs显示文摘Hepatic stellate cells(HSCs)are essential drivers of fibrogenesis.Inducing activated-HSC apoptosis is a promising strategy for treating hepatic fibrosis.18beta-glycyrrhetinic acid(18b-GA)is a natural compound that exists widely in herbal medicines,such as Glycyrrhiza uralensis Fisch,which is used for treating multiple liver diseases,especially in Asia.In the present study,we demonstrated that 18b-GA decreased hepatic fibrosis by inducing the apoptosis in activated HSCs.18b-GA inhibited the expression of a-smooth muscle actin and collagen type Ⅰ alpha-1.Using a chemoproteomic approach derived from activity-based protein profiling,together with cellular thermal shift assay and surface plasmon resonance,we found that 18b-GA covalently targeted peroxiredoxin 1(PRDX1)and peroxiredoxin 2(PRDX2)proteins via binding to active cysteine residues and thereby inhibited their enzymatic activities.18b-GA induced the elevation of reactive oxygen species(ROS),resulting in the apoptosis of activated HSCs.PRDX1 knockdown also led to ROS-mediated apoptosis in activated HSCs.Collectively,our findings revealed the target proteins and molecular mechanisms of 18b-GA in ameliorating hepatic fibrosis,highlighting the future development of 18b-GA as a novel therapeutic drug for hepatic fibrosis.Qian Zhang Piao Luo Liuhai Zheng Jiayun Chen Junzhe Zhang Huan Tang Dandan Liu Xueling He Qiaoli Shi Liwei Gu Jiahao Li Qiuyan Guo Chuanbin Yang Yin Kwan Wong Fei Xia Jigang Wang 2022Journal of Pharmaceutical Analysis2022,12,4:3

8Glycomolecules in Echinococcus granulosus cyst fluid inhibit TLR4-mediated inflammatory responses via c-Raf显示文摘Cystic echinococcosis,which is caused by larval infection of Echinococcus granulosus(E.granulosus)sensu lato,is a widespread chronic cyst-forming helminthic disease that affects up to 3 million people.1 E.granulosus can actively divert the host immune response towards anergy and anti-inflammatory pathways.2 Previous studies have shown that E.granulosus can escape host immunosurveillance by modulating the maturation of dendritic cells(DCs).3,4 Nevertheless,how E.granulosus,an extracellular pathogen,modulates the inflammatory response in DCs remains poorly understood.In this study,we investigated the effects of E.granulosus cyst fluid(EgCF)on bone marrow-derived DCs(BMDCs)exposed to LPS,an inflammatory stimulus,and the mechanisms involved in the EgCF–DCs immune modulation.Jun Hou Linlin Li Dan Dong Lianghai Wang Xian Wang Kun Yang Xiaodan Xu Congzhe Chen Xiangwei Wu Xueling Chen 2020Cellular & Molecular Immunology2020,17,4:3

12Single-cell transcriptome analysis reveals the regulatory effects of artesunate on splenic immune cells in polymicrobial sepsis显示文摘Sepsis is characterized by a severe and life-threatening host immune response to polymicrobial infection accompanied by organ dysfunction.Studies on the therapeutic effect and mechanism of immunomodulatory drugs on the sepsis-induced hyperinflammatory or immunosuppression states of various immune cells remain limited.This study aimed to investigate the protective effects and underlying mechanism of artesunate(ART)on the splenic microenvironment of cecal ligation and puncture-induced sepsis model mice using single-cell RNA sequencing(scRNA-seq)and experimental validations.The scRNA-seq analysis revealed that ART inhibited the activation of pro-inflammatory macrophages recruited during sepsis.ART could restore neutrophils’chemotaxis and immune function in the septic spleen.It inhibited the activation of T regulatory cells but promoted the cytotoxic function of natural killer cells during sepsis.ART also promoted the differentiation and activity of splenic B cells in mice with sepsis.These results indicated that ART could alleviate the inflammatory and/or immunosuppressive states of various immune cells involved in sepsis to balance the immune homeostasis within the host.Overall,this study provided a comprehensive investigation of the regulatory effect of ART on the splenic microenvironment in sepsis,thus contributing to the application of ART as adjunctive therapy for the clinical treatment of sepsis.Jiayun Chen Xueling He Yunmeng Bai Jing Liu Yin Kwan Wong Lulin Xie Qian Zhang Piao Luo Peng Gao Liwei Gu Qiuyan Guo Guangqing Cheng Chen Wang Jigang Wang 2023Journal of Pharmaceutical Analysis2023,13,7:1

19Ion flux dropout observed near dipolarization front显示文摘An ion flux dropout near the dipolarization front(DF) at around XGSM=-11 REin the Earth's plasma sheet was observed by Time History of Events and Macroscale Interaction during substorms(THEMIS) on March31, 2009. The ion differential energy fluxes at energies from 450 e V to 150 ke V measured by the ESA and SST instruments from THC began to decrease about 2 s before the detection of the DF and reached a local minimum 6 s later. Then, the ion fluxes gradually increased to form a dropout around the DF. The spatial extent of the dropout was about 4,000 km. For energies above 20 ke V, the ion fluxes after the dropout are greater than those before it,contrary to the fluxes at energies below 20 ke V. The associated ion density variation indicates that the ion flux dropout coincides with the ion density dropout. Taking advantage of multipoint observations, THD, THC, and THE detected the same DF consecutively. Only THC detected an obvious ion flux dropout; THD observed an indistinct one about 2 s before THC; no high-energy(E [ 30 ke V) ion flux dropout was observed by THE. Our study suggests that the ion flux dropout may evolve withthe earthward-propagating DF, and its properties can depend on locations relative to the DF.Xueling Shi Tao Chen Lingqian Zhang Suping Duan Jiang Liu Zhaohai He 2014Chinese Science Bulletin2014,59,34:1
