| 1 | Sodium oligomannate therapeutically remodels gut microbiota and suppresses gut bacterial amino acids-shaped neuroinflammation to inhibit Alzheimer's disease progression显示文摘Recently,increasing evidence has suggested the association between gut dysbiosis and Alzheimer's disease(AD)progression,yet the role of gut microbiota in AD pathogenesis remains obscure.Herein,we provide a potential mechanistic link between gut microbiota dysbiosis and neuroinflammation in AD progression.Using AD mouse models,we discovered that,during AD progression,the alteration of gut microbiota composition leads to the peripheral accumulation of phenylalanine and isoleucine,which stimulates the differentiation and proliferation of pro-inflammatory T helper 1(Thl)cells.The brain-infiltrated peripheral Th1 immune cells are associated with the Ml microglia aaivation,contributing to AD-associated neuroinflammation.Importantly,the elevation of phenylalanine and isoleucine concentrations and the increase of Th1 cell frequency in the blood were also observed in two small independent cohorts of patients with mild cognitive impairment(MCI)due to AD.Furthermore,GV-971,a sodium oligomannate that has demonstrated solid and consistent cognition improvement in a phase 3 clinical trial in China,suppresses gut dysbiosis and the associated phenylalanine/isoleucine accumulation,harnesses neuroinflammation and reverses the cognition impairment.Together,our findings highlight the role of gut dysbiosis-promoted neuroinflammation in AD progression and suggest a novel strategy for AD therapy by remodelling the gut microbiota. | Xinyi Wang Guangqiang Sun Teng Feng Jing Zhang Xun Huang Tao Wang Zuoquan Xie Xingkun Chu Jun Yang Huan Wang Shuaishuai Chang Yanxue Gong Lingfei Ruan Guanqun Zhang Siyuan Yan Wen Lian Chen Du Dabing Yang Qingli Zhang Feifei Lin Jia Liu Haiyan Zhang Changrong Ge Shifu Xiao Jian Ding Meiyu Geng | 2019 | Cell Research2019，29，10： | 192 |
| 2 | Artesunate synergizes with sorafenib to induce ferroptosis in hepatocellular carcinoma显示文摘Sorafenib is the first-line medication for advanced hepatocellular carcinoma(HCC),but it can only extend limited survival.It is imperative to find a combination strategy to increase sorafenib efficacy.Artesunate is such a preferred candidate,because artesunate is clinically well-tolerated and more importantly both drugs can induce ferroptosis through different mechanisms.In this study we investigated the combined effect of sorafenib and artesunate in inducing ferroptosis of HCC and elucidated the involved molecular mechanisms.We showed that artesunate greatly enhanced the anticancer effects of low dose of sorafenib against Huh7,SNU-449,and SNU-182 HCC cell lines in vitro and against Huh7 cell xenograft model in Balb/c nude mice.The combination index method confirmed that the combined effect of sorafenib and artesunate was synergistic.Compared with the treatment with artesunate or sorafenib alone,combined treatment induced significantly exacerbated lipid peroxidation and ferroptosis,which was blocked by N-acetyl cysteine and ferroptosis inhibitors liproxstatin-1 and deferoxamine mesylate,but not by inhibitors of other types of cell death(z-VAD,necrostatin-1 and belnacasan).In Huh7 cells,we demonstrated that the combined treatment induced oxidative stress and lysosome-mediated ferritinophagy,two essential aspects of ferroptosis.Sorafenib at low dose mainly caused oxidative stress through mitochondrial impairments and SLC7A11-invovled glutathione depletion.Artesunate-induced lysosome activation synergized with sorafenib-mediated pro-oxidative effects by promoting sequential reactions including lysosomal cathepsin B/L activation,ferritin degradation,lipid peroxidation,and consequent ferroptosis.Taken together,artesunate could be repurposed to sensitize sorafenib in HCC treatment.The combined treatment can be easily translated into clinical applications. | Zhong-jie Li Hui-qi Dai Xiao-wei Huang Ji Feng Jing-huan Deng Zi-xuan Wang Xiao-mei Yang Yu-jia Liu Yong Wu Pan-hong Chen Huan Shi Ji-gang Wang Jing Zhou Guo-dong Lu | 2021 | Acta Pharmacologica Sinica2021，42，2： | 31 |
| 3 | Epidemiology, causes, clinical manifestation and diagnosis, prevention and control of coronavirus disease (COVID-19) during the early outbreak period: a scoping review显示文摘Background:The coronavirus disease(COVID-19)has been identified as the cause of an outbreak of respiratory illness in Wuhan,Hubei Province,China beginning in December 2019.As of 31 January 2020,this epidemic had spread to 19 countries with 11791 confirmed cases,including 213 deaths.The World Health Organization has declared it a Public Health Emergency of International Concern.Methods:A scoping review was conducted following the methodological framework suggested by Arksey and O'Malley.In this scoping review,65 research articles published before 31 January 2020 were analyzed and discussed to better understand the epidemiology,causes,clinical diagnosis,prevention and control of this virus.The research domains,dates of publication,journal language,authors'affiliations,and methodological characteristics were included in the analysis.All the findings and statements in this review regarding the outbreak are based on published information as listed in the references.Results:Most of the publications were written using the English language(89.2%).The largest proportion of published articles were related to causes(38.5%)and a majority(67.7%)were published by Chinese scholars.Research articles initially focused on causes,but over time there was an increase of the articles related to prevention and control.Studies thus far have shown that the virus7 origination is in connection to a seafood market in Wuhan,but specific animal associations have not been confirmed.Reported symptoms include fever,cough,fatigue,pneumonia,headache,diarrhea,hemoptysis,and dyspnea.Preventive measures such as masks,hand hygiene practices,avoidance of public contact,case detection,contact tracing,and quarantines have been discussed as ways to reduce transmission.To date,no specific antiviral treatment has proven effective;hence,infected people primarily rely on symptomatic treatment and supportive care.Conclusions:There has been a rapid surge in research in response to the outbreak of COVID-19.During this early period,published research primarily explored the epidemiology,causes,clinical manifestation and diagnosis,as well as prevention and control of the novel coronavirus.Although these studies are relevant to control the current public emergency,more high-quality research is needed to provide valid and reliable ways to manage this kind of public health emergency in both the short-and long-term. | Sasmita Poudel Adhikari Sha Meng Yu-Ju Wu Yu-Ping Mao Rui-Xue Ye Qing-Zhi Wang Chang Sun Sean Sylvia Scott Rozelle Hein Raat Huan Zhou | 2020 | Infectious Diseases of Poverty2020，9，2： | 28 |

| 5 | Activation of SIRT1 ameliorates LPS-induced lung injury in mice via decreasing endothelial tight junction permeability显示文摘The integrity of the endothelial barrier is a determinant of the prognosis of lipopolysaccharide (LPS)-induced acute lung injury (ALI). In this study, we investigated whether and how Sirtuin 1 (SIRT1) maintained the vascular integrity during ALI. An experimental model of ALI was established in mice through intratracheal administration of LPS (10 mg/kg). LPS stimulation significantly increased the pulmonary permeability and decreased the expression of SIRT1 and tight junction proteins (TJs), including occludin, claudin-5, tight junction protein 1 and tight junction protein 2. Morphological studies showed that LPS induced obvious lung injury with inammatory cell infiltration in the interstitial and alveolar space, hemorrhage, edema, and the thickened alveolar wall compared to the control mice. Intratracheal administration of the selective SIRT1 activator SRT1720 (6.25 mg/kg) significantly attenuated LPS- induced lung injury, lung hyper-permeability and increased TJs expression, whereas intratracheal administration of the selective SIRT1 inhibitor EX527 (6.25 mg/kg) aggravated LPS-induced ALI. Similar protective effects of SIRT1 on pulmonary cellular permeability were observed in primary human pulmonary microvascular endothelial cells treated with LPS (2 mg/mL) in vitro. We further demonstrated that the RhoA/ROCK signaling pathway was activated in SIRT1 regulation of tight junction permeability. The RhoA/ROCK inhibitor Y-27632 (10 μM) increased the expression of TJs and reversed LPS- or EX527-induced hyper-permeability. In conclusion, SIRT1 ameliorates LPS-induced lung injury via decreasing endothelial tight junction permeability, possibly via RhoA/ ROCK signaling pathway. This finding may contribute to the development of new therapeutic approaches for lung injury. | Cui-ping Fu Sheng-yu Hao Xiao-bo Xu Jian Zhou Zi-long Liu Huan Lu Li-min Wang Wei-zhong Jin Shan-qun Li | 2019 | Acta Pharmacologica Sinica2019，40，5： | 22 |
| 6 | Effects of glucagon-like peptide-1 receptor agonists on non-alcoholic fatty liver disease and inflammation显示文摘Glucagon-like peptide1(GLP-1)is secreted from Langerhans cells in response to oral nutrient intake.Glucagon-like peptide-1 receptor agonists(GLP-1RAs)are a new class of incretin-based anti-diabetic drugs.They function to stimulate insulin secretion while suppressing glucagon secretion.GLP-1-based therapies are now well established in the management of type 2 diabetes mellitus(T2DM),and recent literature has suggested potential applications of these drugs in the treatment of obesity and for protection against cardiovascular and neurological diseases.As we know,along with change in lifestyles,the prevalence of non-alcoholic fatty liver disease(NAFLD)in China is rising more than that of viral hepatitis and alcoholic fatty liver disease,and NAFLD has become the most common chronic liver disease in recent years.Recent studies further suggest that GLP-1RAs can reduce transaminase levels to improve NAFLD by improving blood lipid levels,cutting down the fatcontent to promote fat redistribution,directly decreasing fatty degeneration of the liver,reducing the degree of liver fibrosis and improving inflammation.This review shows the NAFLD-associated effects of GLP-1RAs in animal models and in patients with T2DM or obesity who are participants in clinical trials. | Xing-Chun Wang Aaron M Gusdon Huan Liu Shen Qu | 2014 | World Journal of Gastroenterology2014，20，40： | 23 |

| 9 | Soil pH impact on microbial tetraether lipids and terrestrial input index (BIT) in China显示文摘The distributions of microbial tetraether lipids i.e. glycerol dialkyl glycerol tetraethers (GDGTs) were investigated in a variety of Chinese soils featured by a wide range of pH values in different climate zones. The bacterial branched GDGTs and archaeal isoprenoid GDGTs were found to be widely distributed in Chinese soils and their relative abundance was controlled primarily by soil pH. The bacterial bGDGTs usually dominate over archaeal iGDGTs in abundance when the soil pH is below 8.0. However archaeal iGDGTs become dominant and the abundance of halophilic archaea characterized by GDGT V without cyclopentyl ring increases dramatically in the alkaline soil with pH greater than 8.0. The relative abundance of archaeal iGDGTs to bacterial bGDGTs was defined here as RAI index. The RAI index decreases with elevated soil pH and a linear correlation is found between them indicating that the relative abundance of archaeal iGDGTs to bacterial bGDGTs increases with increased pH. The RAI index thus could be a novel proxy of the pH values of paleosol. The terrestrial input index BIT (Branched and Isoprenoid Tetraethers Index) decreases with increased soil pH suggesting that soil pH should be taken into consideration when the terrestrial contribution to marine sediments is estimated by BIT index. Moreover the TEX86 index cannot be used to reconstruct sea surface temperature in the sediments featured by a large terrestrial input. | YANG Huan DING WeiHua WANG JinXiang JIN ChengSheng HE GangQiang QIN YangMin XIE ShuCheng | 2012 | Science China Earth Sciences2012，55，2： | 19 |

| 11 | Coinfection with influenza A virus enhances SARS-CoV-2 infectivity显示文摘The upcoming flu season in the Northern Hemisphere merging with the current COVID-19 pandemic raises a potentially severe threat to public health.Through experimental coinfection with influenza A virus(IAV)and either pseudotyped or live SARS-CoV-2 virus,we found that IAV preinfection significantly promoted the infectivity of SARS-CoV-2 in a broad range of cell types.Remarkably,in vivo,increased SARS-CoV-2 viral load and more severe lung damage were observed in mice coinfected with IAV.Moreover,such enhancement of SARS-CoV-2 infectivity was not observed with several other respiratory viruses,likely due to a unique feature of IAV to elevate ACE2 expression.This study illustrates that IAV has a unique ability to aggravate SARS-CoV-2 infection,and thus,prevention of IAV infection is of great significance during the COVID-19 pandemic. | Lei Bai Yongliang Zhao Jiazhen Dong Simeng Liang Ming Guo Xinjin Liu Xin Wang Zhixiang Huang Xiaoyi Sun Zhen Zhang Lianghui Dong Qianyun Liu Yucheng Zheng Danping Niu Min Xiang Kun Song Jiajie Ye Wenchao Zheng Zhidong Tang Mingliang Tang Yu Zhou Chao Shen Li Zhou Yu Chen Huan Yan Ke Lan Ke Xu | 2021 | Cell Research2021，31，4： | 16 |
| 12 | Evidence for a mouse origin of the SARS-CoV-2 Omicron variant显示文摘The rapid accumulation of mutations in the SARS-CoV-2 Omicron variant that enabled its outbreak raises questions as to whether its proximal origin occurred in humans or another mammalian host. Here, we identified 45 point mutations that Omicron acquired since divergence from the B.1.1 lineage. We found that the Omicron spike protein sequence was subjected to stronger positive selection than that of any reported SARS-CoV-2 variants known to evolve persistently in human hosts, suggesting a possibility of hostjumping. The molecular spectrum of mutations(i.e., the relative frequency of the 12 types of base substitutions) acquired by the progenitor of Omicron was significantly different from the spectrum for viruses that evolved in human patients but resembled the spectra associated with virus evolution in a mouse cellular environment. Furthermore, mutations in the Omicron spike protein significantly overlapped with SARS-CoV-2 mutations known to promote adaptation to mouse hosts, particularly through enhanced spike protein binding affinity for the mouse cell entry receptor. Collectively, our results suggest that the progenitor of Omicron jumped from humans to mice, rapidly accumulated mutations conducive to infecting that host,then jumped back into humans, indicating an inter-species evolutionary trajectory for the Omicron outbreak. | Changshuo Wei Ke-Jia Shan Weiguang Wang Shuya Zhang Qing Huan Wenfeng Qian | 2021 | Journal of Genetics and Genomics2021，48，12： | 16 |
| 13 | Plasmacytoid Dendritic Cells Act as the Most Competent Cell Type in Linking Antiviral Innate and Adaptive Immune Responses显示文摘Appropriate in vivo control of plasmacytoid dendritic cell (pDC) recruitment and activation is a fundamental requirement for defense against viral infection. During this process, a pivotal event that influences the outcome of viral infection is the production of high levels of type I interferon by pDCs. In particular, recent research findings showed that pDCs not only shape the nature of innate resistance, but are also responsible for the successful transition from innate to adaptive immunity for viral resistance. In addition, pDCs can differentiate into antigen presenting cells that may regulate tolerance to a given pathogen. Importantly, in a series of recent clinical studies,pDCs appeared to be defective in number and function in conditions of chronic viral diseases such as infected with HIV-1, HBV or HCV. pDC-associated clinical antiviral therapy is also emerging. This review describes research findings exanining the functional and antiviral properties of in vivo pDC plasticity. | Zheng Zhang~1 Fu-Sheng Wang~(1,2) ~1Research Center of Biological Therapy,Beijing 302 Hospital,Beijing 100039,China ~2Research Centre of Biological Therapy,Beijing Institute of Infectious Diseases,Beijing 302 Hospital,100 Xi Si Huan Middle Road,Beijing 100039,China. | 2005 | Cellular & Molecular Immunology2005，2，6： | 16 |
| 14 | Bone marrow stromal cells as a therapeutic treatment for ischemic stroke显示文摘Cerebral ischemia remains the most frequent cause of death and quality-of-life impairments due to neurological deficits, and accounts for the majority of total healthcare costs. However, treatments for cerebral ischemia are limited. Over the last decade, bone marrow stromal cell(BMSC) therapy has emerged as a particularly appealing option, as it is possible to help patients even when initiated days or even weeks after the ischemic insult. BMSCs are a class of multipotent, self-renewing cells that give rise to differentiated progeny when implanted into appropriate tissues. Therapeutic effects of BMSC treatment for ischemic stroke, including sensory and motor recovery, have been reported in pre-clinical studies and clinical trials. In this article, we review the recent progress in BMSC-based therapy for ischemic stroke, focusing on the route of delivery and pre-processing of BMSCs. Selecting an optimal delivery route is of particular importance. The ideal approach, as well as the least risky, for translational applications still requires further identification. Appropriate preprocessing of BMSCs or combination therapy has the benefit of achieving the maximum possible restoration. Further pre-clinical studies are required to determine the time-window for transplantation and the appropriate dosage of cells. | Zizhen Yang Lei Zhu Fangqin Li Jing Wang Huan Wan Yujun Pan | 2014 | Neuroscience Bulletin2014，30，3： | 16 |

| 16 | Behavior of Mold Slag Used for 20Mn23Al Nonmagnetic Steel During Casting显示文摘Because of the addition of significant quantities of aluminum and manganese,the great challenge of casting 20Mn23Al nonmagnetic steel is to design a mold slag that is chemically compatible with this steel composition.A new mold slag with low melting point and low basicity was proposed.The initial slag(the base mold slag)and two corresponding mold slags sampled after 8 min and 15 min were investigated,and the changes of mold slag composition and properties of molten slag were discussed.The results showed that the slag quickly changed in chemical composition to a slag that contained a small quantity of silica and a larger quantity of alumina,and the basicity increased obviously;the heat flux density through the slag film decreased slightly compared with the slag film at 0 min,8 min and 15 min;the mold slag used for nonmagnetic steel was precipitated as CaF2 crystals.The casting experiment shows that the slab has good surface quality without longitudinal face cracks and slag inclusions;the Al2O3 content in the molten slag pool increased with time at the beginning stage,and it can approach equilibrium state after about 600 s. | YU Xiong WEN Guang-hua TANG Ping MA Fan-jun WANG Huan | 2011 | Journal of Iron and Steel Research(International)2011，18，1： | 15 |
| 17 | Electroacupuncture activates enteric glial cells and protects the gut barrier in hemorrhaged rats显示文摘AIM:To investigate whether electroacupuncture ST36 activates enteric glial cells,and alleviates gut inflammation and barrier dysfunction following hemorrhagic shock.METHODS:Sprague-Dawley rats were subjected to approximately 45% total blood loss and randomly divided into seven groups:(1) sham:cannulation,but no hemorrhage;(2) subjected to hemorrhagic shock(HS);(3) electroacupuncture(EA) ST36 after hemorrhage;(4) vagotomy(VGX)/EA:VGX before hemorrhage,then EA ST36;(5) VGX:VGX before hemorrhage;(6) a-bungarotoxin(BGT)/EA:intraperitoneal injection of a-BGT before hemorrhage,then EA ST36; and(7) a-BGT group:a-BGT injection before hemorrhage.Morphological changes in enteric glial cells(EGCs) were observed by immunofluorescence,and glial fibrillary acidic protein(GFAP; a protein marker of enteric glial activation) was evaluated using reverse transcriptase polymerase chain reaction and western blot analysis.Intestinal cytokine levels,gut permeability to 4-k Da fluorescein isothiocyanate(FITC)-dextran,and the expression and distribution of tight junction protein zona occludens(ZO)-1 were also determined.RESULTS:EGCs were distorted following hemorrhage and showed morphological abnormalities.EA ST36 attenuated the morphological changes in EGCs at 6 h,as compared with the VGX,a-BGT and HS groups.EA ST36 increased GFAP expression to a greater degree than in the other groups.EA ST36 decreased intestinal permeability to FITC-dextran(760.5 ± 96.43 ng/m L vs 2466.7 ± 131.60 ng/m L,P < 0.05) and preserved ZO-1 protein expression and localization at 6 h afterhemorrhage compared with the HS group.However,abdominal VGX and a-BGT treatment weakened or eliminated the effects of EA ST36.EA ST36 reduced tumor necrosis factor-a levels in intestinal homogenates after blood loss,while vagotomy or intraperitoneal injection of a-BGT before EA ST36 abolished its antiinflammatory effects.CONCLUSION:EA ST36 attenuates hemorrhageinduced intestinal inflammatory insult,and protects the intestinal barrier integrity,partly via activation of EGCs. | Sen Hu Zeng-Kai Zhao Rui Liu Hai-Bin Wang Chun-Yu Gu Hong-Min Luo Huan Wang Ming-Hua Du Yi Lv Xian Shi | 2015 | World Journal of Gastroenterology2015，21，5： | 15 |
| 18 | Human placenta-derived mesenchymal stem cells loaded on linear ordered collagen scaffold improves functional recovery after completely transected spinal cord injury in canine显示文摘Traumatic spinal cord injury(SCI) is a major challenge in the clinic. In this study, we sought to examine the synergistic effects of linear ordered collagen scaffold(LOCS) and human placenta-derived mesenchymal stem cells(hPMSCs) when transplanted into completely transected beagle dogs. After 36 weeks observation, we found that LOCS+hPMSCs implants promoted better hindlimb locomotor recovery than was observed in the non-treatment(control) group and LOCS group. Histological analysis showed that the regenerated tissue after treatment was well integrated with the host tissue, and dramatically reduced the volume of cystic and chondroitin sulfate proteoglycans(CSPGs) expression. Furthermore, the LOCS+hPMSCs group also showed more neuron-specific βIII-tubulin(Tuj-1)-and NeuN-positive neurons in the lesion area, as well as axonal regeneration, remyelination and synapse formation in the lesion site. Additionally, dogs in the LOCS+hPMSCs group experienced enhanced sprouting of both ascending(CGRP-positive) sensory fibers and descending(5-HT-and TH-positive) motor fibers at the lesion area. All these data together suggested that the combined treatment had beneficial effects on neuronal regeneration and functional improvement in a canine complete transection model. Therefore, LOCS+hPMSCs implantation holds a great promise for bridging the nerve defect and may be clinically useful in the near future. | Sufang Han Zhifeng Xiao Xing Li Huan Zhao Bin Wang Zhixue Qiu Zhi Li Xin Mei Bai Xu Caixia Fan Bing Chen Jin Han Yanzheng Gu Huilin Yang Qin Shi Jianwu Dai | 2018 | Science China(Life Sciences)2018，61，1： | 15 |
| 19 | Evolution of boundary layer ozone in Shijiazhuang,a suburban site on the North China Plain显示文摘The structure of the boundary layer affects the evolution of ozone(O3), and research into this structure will provide important insights for understanding photochemical pollution.In this study, we conducted a one-month observation(from June 15 to July 14, 2016) of the boundary layer meteorological factors as well as O3 and its precursors in Luancheng County,Shijiazhuang(37°53′N, 114°38′E). Our research showed that photochemical pollution in Shijiazhuang is serious, and the mean hourly maximum and mean 8-hr maximum O3 concentrations are 97.9 ± 26.1 and 84.4 ± 22.4 ppbV, respectively. Meteorological factors play a significant role in the formation of O3. High temperatures and southeasterly winds lead to elevated O3 values, and at moderate relative humidity(40%–50%) and medium boundary layer heights(1200–1500 m), O3 production sensitivity occurred in the transitional region between volatile organic compounds(VOC) and nitrogen oxides(NOx) limitations,and the O3 concentration was the highest. The vertical profiles of O3 were also measured by a tethered balloon. The results showed that a large amount of O3 was stored in the residual layer, and the concentration was positively correlated with the O3 concentration measured the previous day. During the daytime of the following day, the contribution of O3 stored in the residual layer to the boundary layer reached 27%± 7% on average. | Wei Zhao Guiqian Tang Huan Yu Yang Yang Yinghong Wang Lili Wang Junlin An Wenkang Gao Bo Hu Mengtian Cheng Xingqin An Xin Li Yuesi Wang | 2019 | Journal of Environmental Sciences2019，31，9： | 15 |
