| 2 | A restoration-promoting integrated floating bed and its experimental performance in eutrophication remediation显示文摘Numerous studies on eutrophication remediation have mainly focused on purifying water first, then restoring submerged macrophytes. A restoration-promoting integrated floating bed(RPIFB) was designed to combine the processes of water purification and macrophyte restoration simultaneously. Two outdoor experiments were conducted to evaluate the ecological functions of the RPIFB. Trial 1 was conducted to compare the eutrophication purification among floating bed, gradual-submerging bed(GSB) and RPIFB technologies. The results illustrated that RPIFB has the best purification capacity. Removal efficiencies of RPIFB for TN, TP, NH+ 4-N, NO-3-N, CODCr, Chlorophyll-a and turbidity were 74.45%, 98.31%, 74.71%, 88.81%, 71.42%, 90.17% and 85%, respectively. In trial 2, influences of depth of GSB and photic area in RPIFB on biota were investigated. When the depth of GSB decreased and the photic area of RPIFB grew, the height of Potamogeton crispus Linn. increased, but the biomass of Canna indica Linn. was reduced. The mortalities of Misgurnus anguillicaudatus and Bellamya aeruginosa in each group were all less than 7%. All results indicated that when the RPIFB was embedded into the eutrophic water, the regime shift from phytoplankton-dominated to macrophyte-dominated state could be promoted. Thus, the RPIFB is a promising remediation technology for eutrophication and submerged macrophyte restoration. | Yiming Guo Yunguo Liu Guangming Zeng Xinjiang Hu Xin Li Dawei Huang Yunqin Liu Yicheng Yin | 2014 | Journal of Environmental Sciences2014，26，5： | 18 |
| 3 | Therapeutic effect in patients with coronary heart disease based on information analysis from Traditional Chinese Medicine four diagnostic methods显示文摘OBJECTIVE:To study information gained by Traditional Chinese Medicine(TCM)four diagnostic methods and characteristics of syndrome development before and after treatment in patients with coronary heart disease,and to probe into assessment indexes of therapeutic effects with distinctive TCM features.METHODS:Information from the four diagnostic methods before and after treatment in 100 patients with coronary heart disease was collected using the TCM interrogation scale,a pulse condition instrument,a tongue-face diagnosis instrument,anda voice diagnosis information collection system.Changes in the four diagnostic method results from before and after treatment were analyzed with frequency analysis and t-test methods.RESULTS:Before treatment,deficiency syndrome complicated with hyperactivity of pathogenic factors was most common.After treatment,deficiency syndrome was most common.This change from complex syndromes to single syndromes indicates disease and syndrome alleviation.Frequencies of symptoms gained by interrogation after treatment for syndrome of deficiency of heart-Qi,syndrome of deficiency of heart-Yin,and turbid phlegm syndrome were all less severe than those before treatment.Parameters of face color,color on all sub-regions of tongue,color of tongue fur,septic and greasy fur,and lip color after treatment all had significant changes.After treatment,part of the voice diagnosis parameters in the deficiency of heart-Yin and turbid phlegm syndromes had significant changes,but no significant changes were found in the deficiency of heart-Qi syndrome.CONCLUSION:Use of the TCM four diagnostic methods can provide an effective basis forTCM syndrome diagnosis,observation of development of state of illness,and evaluation of clinical therapeutic effects. | Yiqin Wang Jin Xu Rui Guo Chaoxia Xu Yiming Hao Chunfeng Chen Yijian Hong Xiangqun Xiao Wenjie Xu Jing Hong Zhao Lei | 2014 | Journal of Traditional Chinese Medicine2014，34，1： | 12 |
| 4 | Tissue-specific transcription reprogramming promotes liver metastasis of colorectal cancer显示文摘Metastasis,the development of secondary malignant growths at a distance from a primary tumor,is the cause of death for 90%of cancer patients,but little is known about how metastatic cancer cells adapt to and colonize new tissue environments.Here,using clinical samples,patient-derived xenograft(PDX)samples,PDX cells,and primary/metastatic cell lines,we discovered that liver metastatic colorectal cancer(CRC)cells lose their colon-specific gene transcription program yet gain a liver-specific gene transcription program.We showed that this transcription reprogramming is driven by a reshaped epigenetic landscape of both typical enhancers and super-enhancers.Further,we identified that the liver-specific transcription factors FOXA2 and HNF1A can bind to the gained enhancers and activate the liver-specific gene transcription,thereby driving CRC liver metastasis.Importantly,similar transcription reprogramming can be observed in multiple cancer types.Our data suggest that reprogrammed tissue-specific transcription promotes metastasis and should be targeted therapeutically. | Shuaishuai Teng Yang Eric Li Ming Yang Rui Qi Yiming Huang Qianyu Wang Yanmei Zhang Shanwen Chen Shasha Li Kequan Lin Yang Cao Qunsheng Ji Qingyang Gu Yujing Cheng Zai Chang Wei Guo Pengyuan Wang Ivan Garcia-Bassets Zhi John Lu Dong Wang | 2020 | Cell Research2020，30，1： | 11 |
| 5 | MdATG18a overexpression improves basal thermotolerance in transgenic apple by decreasing damage to chloroplasts显示文摘High temperature is an abiotic stress factor that threatens plant growth and development.Autophagy in response to heat stress involves the selective removal of heat-induced protein complexes.Previously,we showed that a crucial autophagy protein from apple,MdATG18a,has a positive effect on drought tolerance.In the present study,we treated transgenic apple(Malus domestica)plants overexpressing MdATG18a with high temperature and found that autophagy protected them from heat stress.Overexpression of MdATG18a in apple enhanced antioxidase activity and contributed to the production of increased beneficial antioxidants under heat stress.Transgenic apple plants exhibited higher photosynthetic capacity,as shown by the rate of CO_(2) assimilation,the maximum photochemical efficiency of photosystem II(PSII),the effective quantum yield,and the electron transport rates in photosystems I and II(PSI and PSII,respectively).We also detected elevated autophagic activity and reduced damage to chloroplasts in transgenic plants compared to WT plants.In addition,the transcriptional activities of several HSP genes were increased in transgenic apple plants.In summary,we propose that autophagy plays a critical role in basal thermotolerance in apple,primarily through a combination of enhanced antioxidant activity and reduced chloroplast damage. | Liuqing Huo Xun Sun Zijian Guo Xin Jia Runmin Che Yiming Sun Yanfei Zhu Ping Wang Xiaoqing Gong Fengwang Ma | 2020 | Horticulture Research2020，7，1： | 9 |
| 6 | Focal adhesion protein Kindlin-2 regulates bone homeostasis in mice显示文摘Our recent studies demonstrate that the focal adhesion protein Kindlin-2 is critical for chondrogenesis and early skeletal development. Here, we show that deleting Kindlin-2 from osteoblasts using the 2.3-kb mouse Col1 a1-Cre transgene minimally impacts bone mass in mice, but deleting Kindlin-2 using the 10-kb mouse Dmp1-Cre transgene, which targets osteocytes and mature osteoblasts, results in striking osteopenia in mice. Kindlin-2 loss reduces the osteoblastic population but increases the osteoclastic and adipocytic populations in the bone microenvironment. Kindlin-2 loss upregulates sclerostin in osteocytes,downregulates β-catenin in osteoblasts, and inhibits osteoblast formation and differentiation in vitro and in vivo. Upregulation ofβ-catenin in the mutant cells reverses the osteopenia induced by Kindlin-2 deficiency. Kindlin-2 loss additionally increases the expression of RANKL in osteocytes and increases osteoclast formation and bone resorption. Kindlin-2 deletion in osteocytes promotes osteoclast formation in osteocyte/bone marrow monocyte cocultures, which is significantly blocked by an anti-RANKLneutralizing antibody. Finally, Kindlin-2 loss increases osteocyte apoptosis and impairs osteocyte spreading and dendrite formation.Thus, we demonstrate an important role of Kindlin-2 in the regulation of bone homeostasis and provide a potential target for the treatment of metabolic bone diseases. | Huiling Cao Qinnan Yan Dong Wang Yumei Lai Bo Zhou Qi Zhang Wenfei Jin Simin Lin Yiming Lei Liting Ma Yuxi Guo Yishu Wang Yilin Wang Xiaochun Bai Chuanju Liu Jian QFeng Chuanyue Wu Di Chen Xu Cao Guozhi Xiao | 2020 | Bone Research2020，8，1： | 8 |
| 7 | Electro-mechanically controlled assembly of reconfigurable 3D mesostructures and electronic devices based on dielectric elastomer platforms显示文摘The manufacture of 3D mesostructures is receiving rapidly increasing attention,because of the fundamental significance and practical applications across wide-ranging areas.The recently developed approach of buckling-guided assembly allows deterministic formation of complex 3D mesostructures in a broad set of functional materials;with feature sizes spanning nanoscale to centimeter-scale.Previous studies mostly exploited mechanically controlled assembly platforms using elastomer substrates;which limits the capabilities to achieve on-demand local assembly;and to reshape assembled mesostructures into distinct 3D configurations.This work introduces a set of design concepts and assembly strategies to utilize dielectric elastomer actuators as powerful platforms for the electro-mechanically controlled 3D assembly.Capabilities of sequential-local loading with desired strain distributions allow access to precisely tailored 3D mesostructures that can be reshaped into distinct geometries,as demonstrated by experimental and theoretical studies of?30 examples.A reconfigurable inductive-capacitive radio-frequency circuit consisting of morphable 3D capacitors serves as an application example. | Wenbo Pang Xu Cheng Haojie Zhao Xiaogang Guo Ziyao Ji Guorui Li Yiming Liang Zhaoguo Xue Honglie Song Fan Zhang Zheng Xu Lei Sang Wen Huang Tiefeng Li Yihui Zhang | 2020 | National Science Review2020，7，2： | 8 |
| 8 | Identification of novel cis-elements bound by BplMYB46 involved in abiotic stress responses and secondary wall deposition显示文摘Transcription factors(TFs)play vital roles in various biological processes by binding to cis-acting elements to control expressions of their target genes.The MYB TF BplMYB46,from Betula platyphylla,is involved in abiotic stress responses and secondary wall deposition.In the present study,we used a TF-centered yeast onehybrid technology(TF-centered Y1H)to identify the cisacting elements bound by BplMYB46.We screened a shortinsert random library and identified three cis-elements bound by BplMYB46:an E-box(CA(A/T/C)(A/G/C)TG)and two novel motifs,a TC-box(T(G/A)TCG(C/G))and a GT-box(A(G/T)T(A/C)GT(T/G)C).Chromatin immunoprecipitation(ChIP)and effector-reporter coexpression assays in Nicotiana tabacum confirmed binding of BplMYB46 to the TC-box,GT-box,and E-box motifs in the promoters of the phenylalanine ammonia lyase(PAL),peroxidase(POD),and superoxide dismutase(SOD)genes,which function in abiotic stress tolerance and secondary wall biosynthesis.This finding improves our understanding of potential regulatory mechanisms in the response to abiotic stress and secondary wall deposition of BplMYB46 in B.platyphylla. | Huiyan Guo Liuqiang Wang Chuanping Yang Yiming Zhang Chunrui Zhang Chao Wang | 2018 | Journal of Integrative Plant Biology2018，60，10： | 7 |
| 9 | Scalable microfabrication of three-dimensional porous interconnected graphene scaffolds with carbon spheres for high-performance all carbon-based micro-supercapacitors显示文摘As one of the most important micro energy storage devices(MESDs),graphene-based micro-supercapacitors(G-MSCs)possess the advantages of excellent flexibility,long cycle life,affordability and high reliability.In most cases,constructing three-dimensional(3D)graphene networks is widely utilized to promote the permeation of electrolyte and enhance the utilization of active materials.In this work,conventional freeze-drying process is utilized in the fabrication of G-MSCs to constitute 3D interconnected networks micro-electrodes,and further by regulating the composition of inks,carbon spheres(CSs)at different mass loadings are introduced into the graphene scaffolds to further increase the active sites of the micro-electrodes.The fabricated all carbon-based MSC with the optimal mass loading of CSs(0.406 mg cm^(-2))exhibits a high specific areal capacitance of 17.01mF cm^(-2)at the scan rate of 10mV s^(-1)and a capacitance retention of 93.14%after 10000 cycles at the scan rate of 500 mV s^(-1).The proposed microfabrication process is facile and fully compatible with modern microtechnologies and will be highly suitable for large-scale production and integration. | Yiming Chen Minghao Guo Liang He Wei Yang Lin Xu Jiashen Meng Xiaocong Tian Xinyu Ma Qiang Yu Kaichun Yang Xufeng Hong Liqiang Mai | 2019 | Journal of Materiomics2019，5，2： | 6 |

| 11 | A Joint Learning Framework for the CCKS-2020 Financial Event Extraction Task显示文摘This paper presents a winning solution for the CCKS-2020 financial event extraction task, where the goal is to identify event types, triggers and arguments in sentences across multiple event types. In this task, we focus on resolving two challenging problems(i.e., low resources and element overlapping) by proposing a joint learning framework, named SaltyFishes. We first formulate the event extraction task as a joint probability model. By sharing parameters in the model across different types, we can learn to adapt to low-resource events based on high-resource events. We further address the element overlapping problems by a mechanism of Conditional Layer Normalization, achieving even better extraction accuracy. The overall approach achieves an F1-score of 87.8% which ranks the first place in the competition. | Jiawei Sheng Qian Li Yiming Hei Shu Guo Bowen Yu Lihong Wang Min He Tingwen Liu Hongbo Xu | 2021 | Data Intelligence2021，3，3： | 4 |
| 12 | Effects of antioxidants on homocysteine thiolactone-induced apoptosis in human umbilical vein endothelial cells显示文摘Background and objectives Hyperhomocysteinemia is an independent risk factor for cardiovascular disease. Homocysteine thiolactone (HcyT), one of the homocysteine metabolites in vivo, is toxic both in vivo and in vitro. The aim of this study was to investigate the effect of HcyT on apoptotic damage in human umbilical vein endothelial cells (HUVECs) and the role of antioxidants in the reduction of HcyT-induced apoptosis. Methods HUVECs were cultured in DMEM supplemented with 20% heat inactivated fetal bovine serum cell cultures were maintained in a humidified 5% CO2 atmosphere at 37 ℃. Cytotoxicity was determined by MTT assay,which consists of hypodiploid cells with propidium iodide labeling and intracellular reactive oxygen species levels using 2',7'-dichlorofluorescein diacetate as the probe by flow cytometry. Results HcyT (250-2000μM) induced HUVECs apoptosis in a time- and concentration-dependent manner. Reactive oxygen species levels rose in response to increasing HcyT concentrations at 24-h incubation.The reduction of cell apoptosis by N-acetylcysteine, vitamin E, or pyrrolidine dithiocarbamate, occurred simultaneously with a significant decrease in intracellular reactive oxygen species levels. Conclusion HcyT exerts its cytotoxic effects on endothelial cells through an apoptotic mechanism involving cellular reactive oxygen species production. The capacity of N-acetylcysteine, vitamin E, and pyrrolidine dithiocarbamate to scavenge HcyT-induced cellular reactive oxygen species correlates well with their efficiency to protect against HcyT-promoted apoptotic damage. The protective effect of pyrrolidine dithiocarbamate on cell apoptosis indicates HcyT-generated hydrogen peroxide may provoke cell apoptosis via activating nuclear factor-kappa binding protein. | Weijun GU Juming LU Guoqing YANG Qinghua GUO Baoan WANG Yiming MU Changyu PAN | 2006 | Journal of Geriatric Cardiology2006，3，2： | 3 |
| 13 | The Discovery of Magnesioferrite from Au (Fe, Cu) Magnesian Skarn Deposits and Study of the Magnesioferrite-Magnesiomagnetite Series显示文摘Magnesioferrite, a rare metasomatic mineral, was discovered for the first time in China from the Qinlou Au (Fe, Cu) magnesian skarn deposit, Sanpu, Huaibei, Auhui Province, and the Mulonggou Fe (Mo, Cu) magnesian skarn deposit, Luonan County, Shaanxi Province. In this paper, the geological setting, mineral associations, chemical composition, some physical properties, X-ray powder diffraction data and infrared spectroscopy of magnesioferrite and magnesiomagnetite are discussed. Magnesioferrite contains 17.66%-13.48% of MgO. Its main associated minerals are clinohumite, chondrodite, serpentine,, calcite and magnesiomagnetite. The density of magnesioferrite is 4.537-4.720, reflectances in percent are: 17.8-18.1, hardness is 838-900 kg/mm2, and the cell parameter a0 = 8.371-8.379 A. A systematic study of the magnesioferrite-magnesiomagnetite-magnetite series suggests that along with the increase of magnesioferrite molecules in the mineral, the density, reflectances and cell parameters decrease | ZHAO Yiming ZHANG Yinan BI Chengsi GUO Lihe | 1998 | Acta Geologica Sinica(English Edition)1998，72，4： | 3 |

| 15 | Cyanobacteria-based self-oxygenated photodynamic therapy for anaerobic infection treatment and tissue repair显示文摘Photodynamic therapy(PDT)is an important technique to deal with drug-resistant bacterial infections in the post-antibiotic era.However,the hypoxic environment in intractable infections such as refractory keratitis and periodontitis,makes PDT more difficult.In this work,spontaneous oxygen-producing cyanobacteria were used as the carrier of photosensitizer(Ce6),and ultrasmall Cu_(5.4)O nanoparticles(Cu_(5.4)O USNPs)with catalase activity for infection and inflammation elimination and rapid tissue repair(CeCycn-Cu_(5.4)O).The loading of Ce6 and Cu_(5.4)O USNPs onto cyanobacteria surface were confirmed by transmission electron microscopy,nano particle size analyzer,scanning electron microscopy.In vitro sterilization and biofilm removal experiments demonstrated that the restriction of hypoxic environment to PDT was significantly alleviated due to the oxygen production of cyanobacteria.Under laser irradiation,the close transfer of energy photons to oxygen produced by cyanobacteria reduced more than 90% of Ce6 dosages(660 nm,200 mW/cm^(2),2 min).It is worth mentioning that both rapid sterilization through PDT and long-term oxidized free radicals elimination were achieved by adjusting the ratio of Ce6 and Cu_(5.4)O USNPs.Both periodontitis and refractory keratitis animal models proved the excellent self-oxygenation enhanced antibacterial property and promotion of tissue repair. | Bailiang Wang Liyang Zhou Yishun Guo Hanwen Guo Yiming Zhong Xiaomin Huang Yifan Ge Qingying Wang Xiaoying Chu Yingying Jin Kaiyue Lan Mei Yang Jia Qu | 2022 | Bioactive Materials2022，7，6： | 3 |
| 16 | Redevelopment of urban brownfield sites in China:Motivation,history,policies and improved management显示文摘Rapid urbanisation in China has resulted in an increased demand for land in towns and cities.To upgrade and modernise,China has also moved many major industries from urban centres to less populated areas.With the high economic value of urban land,the transformation and utilisation of brownfield areas have become important economically and socially.The Chinese government has recognised the need for strong frameworks to safeguard soil and groundwater quality,with brownfield sites a key category for management.Strong scientific,regulatory and decision-making frameworks are needed and being adopted to ensure practical,careful and wise use of central and localised government resources,to manage the reuse and regeneration of these brownfield sites.This paper reviews the context,policies and management procedures of developing brownfield sites in countries with a history of brownfield management and discusses China’s current situation and priorities for brownfield governance and redevelopment.These include(1)clarification of brownfield site soil contamination risk control standards and risk assessment procedures,(2)the responsibilities of different national and local agencies,(3)the establishment of a national expert committee to advise on best practices,policy and process,(4)the use of registered brownfield databases at national,provincial,municipal and county levels,and(5)the set up of soil pollution prevention fund at the provincial level. | Yiming Sun Hong Li Shuo Lei Kirk TSemple Frederic Coulon Qing Hu Jingyang Gao Guanlin Guo Qingbao Gu Kevin C.Jones | 2022 | Eco-Environment & Health2022，1，2： | 2 |
| 17 | Treated dentin matrix induces odontogenic differentiation of dental pulp stem cells via regulation of Wnt/β-catenin signaling显示文摘Treated dentin matrix(TDM)is an ideal scaffold material containing multiple extracellular matrix factors.The canonical Wnt signaling pathway is necessary for tooth regeneration.Thus,this study investigated whether the TDM can promote the odontogenic differentiation of human dental pulp stem cells(hDPSCs)and determined the potential role of Wnt/β-catenin signaling in this process.Different concentrations of TDM promoted the dental differentiation of the hDPSCs and meanwhile,the expression of GSK3βwas decreased.Of note,the expression of the Wnt/β-catenin pathway-related genes changed significantly in the context of TDM induction,as per RNA sequencing(RNA seq)data.In addition,the experiment showed that new dentin was visible in rat mandible cultured with TDM,and the thickness was significantly thicker than that of the control group.In addition,immunohistochemical staining showed lower GSK3βexpression in new dentin.Consistently,the GSK3βknockdown hDPSCs performed enhanced odotogenesis compared with the control groups.However,GSK3βoverexpressing could decrease odotogenesis of TDM-induced hDPSCs.These results were confirmed in immunodeficient mice and Wistar rats.These suggest that TDM promotes odontogenic differentiation of hDPSCs by directly targeting GSK3βand activating the canonical Wnt/β-catenin signaling pathway and provide a theoretical basis for tooth regeneration engineering. | Sirui Liu Jingjing Sun Shuai Yuan Yanyu Yang Yuping Gong Ying Wang Runying Guo Xue Zhang Yiming Liu Hongyan Mi Meiyue Wang Mengzhe Liu Rui Li | 2022 | Bioactive Materials2022，7，1： | 2 |

| 19 | Neutrophil extracellular traps contribute to myofibroblast differentiation and scar hyperplasia through the Toll-like receptor 9/nuclear factor Kappa-B/interleukin-6 pathway显示文摘Background:Inflammation is an important factor in pathological scarring.The role of neutrophils,one of the most important inflammatory cells,in scar hyperplasia remains unclear.The purpose of this article is to study the correlation between neutrophil extracellular traps(NETs)and scar hyperplasia and identify a new target for inhibiting scar hyperplasia.Methods:Neutrophils were isolated from human peripheral blood by magnetic-bead sorting.NETs in plasma and scars were detected by enzyme-linked immunosorbent assays(ELISAs),immunofluorescence and flow cytometry.Immunohistochemistry was used to assess neutrophil(CD66B)infiltration in hypertrophic scars.To observe the entry of NETs into fibroblasts we used immunofluorescence and flow cytometry.Results:We found that peripheral blood neutrophils in patients with hypertrophic scars were more likely to form NETs(p<0.05).Hypertrophic scars showed greater infiltration with neutrophils and NETs(p<0.05).NETs activate fibroblasts in vitro to promote their differentiation and migration.Inhibition of NETs with cytochalasin in wounds reduced the hyperplasia of scars in mice.We induced neutrophils to generate NETs with different stimuli in vitro and detected the proteins carried by NETs.We did not find an increase in the expression of common scarring factors[interleukin(IL)-17 and transforming growth factor-β(TGF-β),p>0.05].However,inhibiting the production of NETs or degrading DNA reduced the differentiation of fibroblasts intomyofibroblasts.In vitro,NETs were found to be mediated by Toll-like receptor 9(TLR-9)in fibroblasts and further phosphorylated nuclear factor Kappa-B(NF-κB).We found that IL-6,which is downstream of NF-κB,was increased in fibroblasts.Additionally,IL-6 uses autocrine and paracrine signaling to promote differentiation and secretion.Conclusions:Our experiments found that NETs activate fibroblasts through the TLR-9/NF-κB/IL-6 pathway,thereby providing a new target for regulating hypertrophic scars. | Yiming Shao Zaiwen Guo Yunxi Yang Lu Liu Jiamin Huang Yi Chen Linbin Li Bingwei Sun | 2022 | Burns & Trauma2022，10，1： | 2 |
| 20 | Shugan Huoxue Huayu Fang(疏肝活血化瘀方)attenuates carbon tetrachloride-induced hepatic fibrosis in rats by inhibiting transforming growth factor-β1/Smad signaling显示文摘OBJECTIVE:To investigate the potential mechanism by which Shugan Huoxue Huayu Fang(疏肝活血化瘀方,SGHXHYF)ameliorates liver fibrosis.METHODS:Liver fibrosis was induced in rats by intraperitoneal injection of carbon tetrachloride(CCl_(4))in peanut oil solution(40%,3 m L/kg body weight)twice a week for 8 weeks.A normal control group received the same volume of peanut oil alone.During weeks 5-8,the CCl_(4)-injected rat groups were administered saline(vehicle control),colchicine(0.1 mg/mL,1 mg/kg,positive control),or SGHXHYF(0.1 mg/mL;0.3,0.6 and 1.2 mg/kg)once daily by oral gavage.Rats were sacrificed 24 h after the last treatment.Blood samples were collected for measurement of serum alanine aminotransferase(ALT),aspartate aminotransferase(AST),alkaline phosphatase(ALP),albumin(ALB),collagenⅠ,and collagenⅢlevels.Liver samples were analyzed by histopathological staining,Masson's staining of extracellular matrix proteins,and immune-ohistochemical staining ofα-smooth muscle actin(α-SMA).TGF-β1/Smad protein and mRNA levels were analyzed by Western blot and quantitative reverse transcription-polymerase chain reaction analysis,respectively.In vitro experiments were also performed using rat hepatic stellate cells(HSCs).RESULTS:Compared with the control animals,CCl_(4)-exposed rats exhibited elevated serum levels of ALT,AST,ALP,collagenⅠ,and collagenⅢ;reduced serum levels of ALB;and increased collagen deposition andα-SMA expression in liver sections,reflecting liver fibrosis.CCl_(4) also increased expression of TGF-β1 and the activated(phosphorylated)forms of Smad2 and Smad3 but reduced expression of the negative regulator Smad7 in the liver.Notably,concomitant administration of SGHXHYF to CCl_(4)-exposed rats was found to significantly reverse or abolish the pro-fibrotic effects of CCl_(4) in the liver and reduced serum transferase levels.Analysis of HSCs in vitro confirmed that,mechanistically,SGHXHYF inhibited activation of the TGF-β1/Smad signaling pathway by downregulating phosphorylated Smad2 and Smad3 and upregulating Smad7 levels.CONCLUSION:SGHXHYF ameliorated CCl_(4)-induced liver fibrosis by inhibiting the TGF-β1/Smad signaling pathway.These findings suggest that SGHXHYF may have clinical utility for the treatment or prevention of liver fibrosis. | LIU Lei GUO Hanbin SHAO Cuiping WANG Lin XU Youqing ZHOU Yiming | 2022 | Journal of Traditional Chinese Medicine2022，42，1： | 2 |
