| 1 | Ore-forming event and geodynamic setting of molybdenum deposit at Wenquan in Gansu Province,Western Qinling显示文摘The Wenquan molybdenum deposit is associated with a Triassic granite in this area.The Wenquan granite is enriched in LILE and LREE,poor in HFSE,and has significantly higher contents of alkali(K2O+Na2O) and Sr,Ba than those of the island arc volcanic rocks.These geochemical characteristics are similar to post-collisional granites in high K calc-alkaline series.Studies of major elements,trace elements,REEs and chronology of the Wenquan pluton show that,in the geodynamic transition stage of continent-continent convergence to extension,the partial melting of the enriched lithospheric mantle generated the basaltic magma and triggered the partial melting of the thickened lower crust which produceded the acidic magma,and the Wenquan pluton was formed by mixing of the two magmas.Molybdenite Re-Os isotopic dating gave Os model ages of 212.7±2.6 Ma to 215.1±2.6 Ma with a weighted mean of 214.1±1.1 Ma,and an Re-Os isochron age of 214.4±7.1 Ma.These ages are close to K-Ar ages(223 to 226 Ma) and a SHRIMP zircon U-Pb age(223±7 Ma) for the Wenquan granite within the error range,but relatively younger.This implies that the Mo mineralization occurred in a late stage of the magmatic intrusion,and the metallogenesis took place in the transition stage from syn-collision to post-collision in the tectonic setting of the Qinling Orogenic Belt(QOB) after continental collision be-tween the North China Block(NCB) and the South China Block(SCB).This process is also corre-sponding to the geological events of metamorphism and deformation in South Qinling,closure of the Mian-Lue oceanic basin,and exhumation of the Dabie-Sulu ultrahigh-pressure metamorphic rocks.The large-scale continent-continent collision between NCB and SCB in the middle Triassic triggered sig-nificant crustal thickening and exhumation of subducted slab.In the late Triassic,the tectonic setting was transformed to the transition stage from collision to extension.Materials from the asthenospheric mantle would ascend into the root of the lower crust,which could induce partial melting of the lower crust and generate Mo-enriched granitic magma.The ore-forming elements enriched in the fluid derived from the condensation and fraction of the magma resulted in the Mo mineralization.The Mo deposits in the QOB are mainly formed in two episodes,namely 220± Ma and 140± Ma.The two episodes of metal-logenesis were developed in the tectonic transition settings from compression to extension,but they were in the different stages of the tectonic evolution.The occurrence of the Wenquan Mo-bearing plu-ton indicates that the Triassic tectonic-magmatic belt of Western Qinling is another favorable region for Mo mineralization in the QOB.Therefore,it is significant to pay more attention to evaluation of the ore-forming potentiality in the Triassic granites in Western Qinling. | ZHU LaiMin DING ZhenJu YAO ShuZhen ZHANG GuoWei SONG ShiGang QU WenJun GUO Bo LEE Ben | 2009 | Chinese Science Bulletin2009，54，13： | 12 |
| 2 | Water regime-nitrogen fertilizer incorporation interaction:Field study on methane and nitrous oxide emissions from a rice agroecosystem in Harbin, China显示文摘Water regime and nitrogen(N) fertilizer are two important factors impacting greenhouse gases(GHG) emission from paddy field, whereas their effects have not been well studied in cold region. In this study, we conducted a two-year field experiment to study the impacts of water regime and N fertilizer on rice yields and GHG emissions in Harbin, China, a cold region located in high latitudes. Our results showed that intermittent irrigation significantly decreased methane(CH_4) emission compared with continuous flooding, however,the decrement was far lower than the global average level. The N_2O emissions were very small when flooded but peaked at the beginning of the disappearance of floodwater. The N fertilizer treatments increased CH_4 emissions at low level(75 kg N/ha). But both CH_4 and N_2O emissions were uninfluenced at the levels of 150 kg N/ha and 225 kg N/ha. Rice yields increased under intermittent irrigation and were highest at the level of 150 kg N/ha. From our results, we recommended that the intermittent irrigation and 150 kg N/ha as the ideal water regime-nitrogen fertilizer incorporation for this area to achieve low GHG emissions without impacting rice yields. | Wenjun Dong Jia Guo Lijun Xu Zhifeng Song Jun Zhang Ao Tang Xijuan Zhang Chunxu Leng Youhong Liu Lianmin Wang Lizhi Wang Yang Yu Zhongliang Yang Yilei Yu Ying Meng Yongcai Lai | 2018 | Journal of Environmental Sciences2018，30，2： | 12 |
| 3 | Recent Advances in Tumor Microenvironment Hydrogen Peroxide-Responsive Materials for Cancer Photodynamic Therapy显示文摘Photodynamic therapy(PDT),as one of the noninvasive clinical cancer phototherapies,suffers from the key drawback associated with hypoxia at the tumor microenvironment(TME),which plays an important role in protecting tumor cells from damage caused by common treatments.High concentration of hydrogen peroxide(H2O2),one of the hallmarks of TME,has been recognized as a double-edged sword,posing both challenges,and opportunities for cancer therapy.The promising perspectives,strategies,and approaches for enhanced tumor therapies,including PDT,have been developed based on the fast advances in H2O2-enabled theranostic nanomedicine.In this review,we outline the latest advances in H2O2-responsive materials,including organic and inorganic materials for enhanced PDT.Finally,the challenges and opportunities for further research on H2O2-responsive anticancer agents are envisioned. | Nan Yang Wanyue Xiao Xuejiao Song Wenjun Wang Xiaochen Dong | 2020 | Nano-Micro Letters2020，12，1： | 11 |
| 4 | Reducing oxidative stress and hepatoprotective effect of water extracts from Pu-erh tea on rats with high-fat diet显示文摘Reducing oxidative stress and hepatoprotective effect of Pu-erh tea water extracts on rats fed with high-fat diet were researched for explaining health care of Pu-erh tea.Fifty SD rats were divided into five groups.The body weight was measured once a day.The malondialdehyde(MDA)and glucose(Glu)levels and the activities of alanine aminotransferase(ALT),aspartate aminotransferase(AST),nitric oxide synthase(NOS),and pyruvate kinase(PK)in serum were determined.Furthermore,the hepatic glycogen level(HGL)and the activities of hepatic total superoxide dismutase(T-SOD),catalase(CAT),and glutathione peroxidase(GSH-Px)were also measured after continuous administration for 12 weeks.The result demonstrated that Pu-erh extract caused the decreases in body weight,fat index,MDA and NOS levels,and the increases in hepatic T-SOD,CAT and GSH-Px activities,indicating that the extract may be due to inhibiting the increases of body weight and fat index,reducing oxidant stress state and inhibiting lipid peroxidation,thus decreasing the activities of ALT and AST,and protecting the liver in rat.Meanwhile,the extracts could increase the production of hepatic glycogen and the activity of PK,and reduce glucose level,protecting the liver from the diseases associated with type II diabetes. | Jingjing Su Xueqing Wang Wenjun Song Xiaoli Bai Changwen Li | 2016 | Food Science and Human Wellness2016，5，4： | 9 |
| 5 | Clarifying the roles of grain boundary and grain orientation on the corrosion and discharge processes of α-Mg based Mg-Li alloys for primary Mg-air batteries显示文摘The corrosion behavior at open circuit potential(OCP)and discharge properties under applied anodic currents of twoα-Mg based Mg-Li alloys,i.e.,LAZ131 and LAZ531,with different microstructural features for primary Mg-air batteries are investigated.The results show that the grain boundaries contribute equally to the corrosion and discharge processes,which are attacked preferentially than the grain interiors and accelerate the dissolution processes ofα-Mg based Mg-Li alloys.The(10-10)/(11-20)orientated grains are attacked preferentially than the(0002)orientated grains on the corrosion and discharge process.The increased corrosion rate and improved discharge properties are attributed to the refinement of grain size,decreased content of(0002)orientated grains and increased content of(10-10)/(11-20)orientated grains.Of those,the LAZ531 alloy possesses high and steady discharge voltage at small discharge current density for long time,with the values of 1.4801 V at 2.5 mA cm^(-2)and 1.3742 V at 10 mA cm^(-2). | Huabao Yang Liang Wu Bin Jiang Wenjun Liu Jiangfeng Song Guangsheng Huang Dingfei Zhang Fusheng Pan | 2021 | Journal of Materials Science & Technology2021，，3： | 9 |
| 6 | Tree-ring-based annual precipitation reconstruction in Kalaqin, Inner Mongolia for the last 238 years显示文摘A tree-ring-width chronology of Pinus tabulaeformis from Kalaqin, Inner Mongolia was developed using modern dendroc hronological techniques. Based on the results of correlation function analysis, the total precipitation from the previous August to current July was reconstructed for 1771-2008 AD with an explained variance of 49.3%. The reconstruction correlated well with the dryness/wetness series derived from historical documents, as well as the precipitation reconstruction of the Chifeng-Weichang region. There were eight intervals with greater precipitation than the average (associated with the strong East Asian summer monsoon) and seven intervals lower than the average (weak monsoon). A power spectrum analysis showed that there were 120 a, 80 a, 8 a and 2 a periodicities. | LIU Yu WANG CaiYong HAO WenJun SONG HuiMing CAI QiuFang TIAN Hua SUN Bo Hans W.

| 7 | Whole genome sequencing of 10K patients with acute ischaemic stroke or transient ischaemic attack: design, methods and baseline patient characteristics显示文摘Background and purpose Stroke is the second leading cause of death worldwide and the leading cause of mortality and long-term disability in China,but its underlying risk genes and pathways are far from being comprehensively understood.We here describe the design and methods of whole genome sequencing(WGS)for 10914 patients with acute ischaemic stroke or transient ischaemic attack from the Third China National Stroke Registry(CNSR-III).Methods Baseline clinical characteristics of the included patients in this study were reported.DNA was extracted from white blood cells of participants.Libraries are constructed using qualified DNA,and WGS is conducted on BGISEQ-500 platform.The average depth is intended to be greater than 30×for each subject.Afterwards,Sentieon software is applied to process the sequencing data under the Genome Analysis Toolkit best practice guidance to call genotypes of single nucleotide variants(SNVs)and insertion-deletions.For each included subject,21 fingerprint SNVs are genotyped by MassARRAY assays to verify that DNA sample and sequencing data originate from the same individual.The copy number variations and structural variations are also called for each patient.All of the genetic variants are annotated and predicted by bioinformatics software or by reviewing public databases.Results The average age of the included 10914 patients was 62.2±11.3 years,and 31.4%patients were women.Most of the baseline clinical characteristics of the 10914 and the excluded patients were balanced.Conclusions The WGS data together with abundant clinical and imaging data of CNSR-III could provide opportunity to elucidate the molecular mechanisms and discover novel therapeutic targets for stroke. | Si Cheng Zhe Xu Yang Liu Jinxi Lin Yong Jiang Yilong Wang Xia Meng Anxin Wang Xinying Huang Zhimin Wang Guohua Chen Songdi Wu Zhengchang Jia Yongming Chen Xuerong Qiu Jun Wu Binbin Song Weizhong Ji Zhongping An Wenjun Xue Lili Zhao Yu Geng Hongyan Li Hao Li Yongjun Wang | 2021 | Stroke & Vascular Neurology2021，6，2： | 8 |
| 8 | Super stable CsPbBr3@SiO2 tumor imaging reagent by stress-response encapsulation显示文摘Great photoelectric properties can herald the high potentials of CsPbBr3 nanocrystals(NCs)to function as the fluorescent probes for early tumor diagnosis.However,the intrinsic water vulnerability of CsPbBr3 NCs highly restricts their biomedical applications.To conquer this challenge,we herein introduce a nature inspired'stress-response'method to tightly encapsulate CsPbBr3 into SiO2 nano-shells that can dramatically improve the water stability of CsPbBr3@SiO2 nanoparticles for over 48 h.We further highlighted the advantageous features of CsPbBr3@SiO2 by using them as the fluorescent probes for CT26 tumor cell imaging with their high water stability,biocompatibility,and low cytotoxicity.Our work for the first time exhibited the potential of lead halide perovskite NCs for tumor diagnosis,and can highly anticipate the further in vivo biomedical applications that light up live cells. | Wentao Song Yiming Wang Bing Wang Yingfang Yao Wenguang Wang Jinhui Wu Qing Shen Wenjun Luo Zhigang Zou | 2020 | Nano Research2020，13，3： | 7 |

| 10 | Interference-Free Pilot Design and Channel Estimation Using ZCZ Sequences for MIMO-OFDM-Based C-V2X Communications显示文摘Cellular vehicle-to-everything(C-V2X) communications is regarded as a promising and feasible solution for 5G-enabled vehicular communications and networking. In this paper, we investigate the pilot design and channel estimation problem in MIMO-OFDM-based C-V2X systems with severe co-channel interference due to spectrum reusing among different V2X communication links. By using zero-correlation zone(ZCZ) sequences, we provide an interference-free pilot design scheme and a corresponding time-domain(TD) correlation-based channel estimation(TD-CCE) method. We employ the ZCZ sequences from the same family set to be designed as the TD pilot symbols and guarantee the pilot sequeneces for neighboring V2X communication links are code-division multiplexing(CDM). The co-channel pilot interference of the deisgned pilot symbols can be effectively eliminated by exploiting the provided TD-CCE method. Simulation results indicate that the accuracy of channel estimation can be effectively improved by the proposed scheme, whose performance is close to that of the non-interference situation. | Haibin Chen Rongqing Zhang Wenjun Zhai Xiaoli Liang Guojuan Song | 2018 | China Communications2018，15，7： | 5 |
| 11 | Tensile and fracture properties of Ti-62A alloy plate with different microstructures显示文摘Ti-62A alloy plates with three different types of microstructure, fully equiaxed, bimodal, and Widmanst tten, were obtained by various heat treatments to investigate the effects of microstructure on the tensile and fracture properties at room temperature. The results reveal that Widmanst tten microstructure exhibits good damage tolerance behavior considering strength, fracture toughness, and fatigue crack growth behavior, while the bimodal microstructure shows good comprehensive properties considering the plasticity synthetically. Optical microscopy (OM) and scanning electron microscopy (SEM) microstructure analyses on fracture and fatigue crack path demonstrate that the dependence of mechanical properties and fatigue crack growth behavior on microstructural feature are attributed to the α lamellae width and the α colony size. | LIU Rui HUI Songxiao YE Wenjun YU Yang FU Yanyan SONG Xiaoyun DENG Xiguang | 2012 | Rare Metals2012，31，5： | 5 |

| 13 | Use of rare earth elements in single-atom site catalysis:A critical review——Commemorating the 100th anniversary of the birth of Academician Guangxian Xu显示文摘Rare earth metals are strategic resources with potential applications in optics,metallurgy and catalysis.In recent years,single-atom site catalysts(SASCs) have attracted increasing attention owing to their 100%atom efficiency and unique catalytic performances.Over the past decade,rare earth elements,including rare earth metals and their oxides,have shown great potential in SASCs.However,systematic analyses of data are still handful.In this mini-review,the use of rare earth metals and their oxides in SASCs was summarized and the results are discussed.A particular focus was paid to the synthetic strategies,characterization of rare earth-containing SASCs,and applications as catalysis supports,promoters and active sites.Current issues faced by rare-earth metals and their oxides in SASCs,as well as future prospects were also provided. | Ningqiang Zhang Han Yan Lingcong Li Rui Wu Liyun Song Guizhen Zhang Wenjun Liang Hong He | 2021 | Journal of Rare Earths2021，39，3： | 4 |
| 14 | Martensitic transformation of Ti-18Nb(at.%) alloy with zirconium显示文摘The addition of 3%~9% Zr on the martensitic transformation of Ti-18Nb(at.%) alloy was investigated. The results of microstructure and X-ray diffraction (XRD) analysis show that the phase constitution of as-quenched Ti-18Nb-9Zr(at.%) alloy consists of the retained matrix and martensite, while that of the other three alloys is single martensite. No trace of athermal phase was found in any of the as-quenched alloys. Unlike the effect of Nb addition on the martensitic transformation start temperature Ms of Ti-18Nb(at.%) alloy, Ms de-creased nonlinearly as increasing the Zr addition from 3% to 9% and Ms decreased much more sharply as increasing the Zr addition. The Ms of as-quenched Ti-18Nb-9Zr alloy was around room temperature. The effect of Zr addition on the phase stabilizing in the Ti-18Nb(at.%) alloy was briefly discussed. | Ye, Wenjun Mi, Xujun Song, Xiaoyun | 2012 | Rare Metals2012，31，3： | 4 |
| 15 | MRI and Transvaginal Ultrasound Findings of Atypical Polypoid Adenomyoma: A Case Report显示文摘Atypical polypoid adenomyoma(APA)is an uncommon type of polypoid characterized by fibroid stroma and endometrial glands.It occurs mostly in premenopausal women and rarely in postmenopausal women with irregular vaginal bleeding.In our current case,a 76-year-old woman presented with irregular vaginal bleeding.The final pathological diagnosis of the mass was APA.APA is not easy to diagnose before surgery.On the one hand,there was no obvious particularity in imaging features and clinical features,especially for uncomfortably identifying endometrial cancer.On the other hand,APA has a pedicle,attaching to any part of the uterine cavity,which can cause pseudocoel between the mass with the uterine cavity wall.So,when it comes to getting the pathological tissue in the absence of hysteroscopy,it is easy to access to the pseudocoel and obtain endometrial tissue rather than the pathological tissue of the mass.Therefore,preoperative imaging examination is of great significance diagnosis way of thinking to clinicians for APA.In the meantime,pathological tissue of APA can be obtained by hysteroscopy in visual conditions. | Ya Tan Xue Hu Xin Song Wenjun Zhang | 2022 | Chinese Medical Sciences Journal2022，37，1： | 3 |
| 16 | High-temperature mechanical properties of as-extruded AZ80 magnesium alloy at different strain rates显示文摘The mechanical properties of as-extruded AZ80 magnesium alloy at temperatures of 450-525℃ and strain rates of 3.0 s^(−1)and 0.15 s^(−1)were investigated by tensile tests.Zero ductility of alloy appeared at 500℃ with a strain rate of 0.15 s^(−1),while the zero strength and zero ductility of the alloy were obtained nearly simultaneously at 525℃ with a strain rate of 3.0 s^(−1).The results indicated that the lower strain rate accelerated the arrival of zero ductility.As the temperature increased,the failure mode of the alloy developed from trans-granular fracture to cleavage fracture and then to inter-granular fracture with the feature of sugar-like grains and fusion traces.The existence of the low-melting composite ofβ-Mg_(17)Al_(12) and Al_(8)Mn_(5) particles segregated near the Mg_(17)Al_(12) phase along grain boundaries were demonstrated to be the reason for the brittle fracturing of the AZ80 alloy at high temperatures.Furthermore,microstructural evolution at temperatures approaching the solidus temperature was discussed to clarify magnesium alloy’s high temperature deformation mechanism. | Wenjun Liu Bin Jiang Hongchen Xiang Qing Ye Shengqi Xia Siqiang Chen Jiangfeng Song Yanlong Ma Mingbo Yang | 2022 | International Journal of Minerals,Metallurgy and Materials2022，29，7： | 3 |
| 17 | Ginsenoside Rb1 Reduces D-GalN/LPS-induced Acute Liver Injury by Regulating TLR4/NF-κB Signaling and NLRP3 Inflammasome显示文摘Background and Aims:The effect of ginsenoside Rb1 on D-galactosamine(D-GalN)/lipopolysaccharide(LPS)-induced acute liver injury(ALI)is unknown.The aim of this study was to evaluate the effect of ginsenoside Rb1 on ALI and its underlying mechanisms.Methods:Mice were pretreated with ginsenoside Rb1 by intraperitoneal injection for 3 days before D-GalN/LPS treatment,to induce ALI.The survival rate was monitored every hour for 24 h,and serum biochemical parameters,hepatic index and histopathological analysis were evaluated to measure the degree of liver injury.ELISA was used to detect oxidative stress and inflammatory cytokines in hepatic tissue and serum.Immunohistochemistry staining,RT-PCR and western blotting were performed to evaluate the expression of toll-like receptor 4(TLR4),nuclear factorkappa B(NF-κB),and NLR family,pyrin domain-containing 3 protein(NLRP3)in liver tissue and Kupffer cells(KCs).Results:Ginsenoside Rb1 improved survival with D-GalN/LPS-induced ALI by up to 80%,significantly ameliorated the increased alanine and aspartate transaminase,restored the hepatic pathological changes and reduced the levels of oxidative stress and inflammatory cytokines altered by D-GalN/LPS.Compared to the control group,the KCs were increased in the D-GalN/LPS groups but did not increase significantly with Rb1 pretreatment.D-GalN/LPS could upregulate while Rb1 pretreatment could downregulate the expression of interleukin(IL)-1β,IL-18,NLRP3,apoptosis associated specklike protein containing CARD(ASC)and caspase-1 in isolated KCs.Furthermore,ginsenoside Rb1 inhibited activation of the TLR4/NF-κB signaling pathway and NLRP3 inflammasome induced by D-GalN/LPS administration.Conclusions:Ginsenoside Rb1 protects mice against D-GalN/LPS-induced ALI by attenuating oxidative stress and the inflammatory response through the TLR4/NF-κB signaling pathway and NLRP3 inflammasome activation. | Yimei Liu Ninghua Liu Yujing Liu Hongyu He Zhe Luo Wenjun Liu Nan Song Minjie Ju | 2022 | Journal of Clinical and Translational Hepatology2022，10，3： | 2 |
| 18 | Endothelial METRNL determines circulating METRNL level and maintains endothelial function against atherosclerosis显示文摘METRNL is a recently identified secreted protein with emerging functions.This study is to find major cellular source of circulating METRNL and to determine METRNL novel function.Here,we show METRNL is abundant in human and mouse vascular endothelium and released by endothelial cells using endoplasmic reticulum-Golgi apparatus pathway.By creating endothelial cell-specific Metrnl knockout mice,combined with bone marrow transplantation to produce bone marrow-specific deletion of Metrnl,we demonstrate that most of circulating METRNL(approximately 75%)originates from the endothelial cells.Both endothelial and circulating METRNL decrease in atherosclerosis mice and patients.By generating endothelial cell-specific Metrnl knockout in apolipoprotein E-deficient mice,combined with bone marrow-specific deletion of Metrnl in apolipoprotein E-deficient mice,we further demonstrate that endothelial METRNL deficiency accelerates atherosclerosis.Mechanically,endothelial METRNL deficiency causes vascular endothelial dysfunction including vasodilation impairment via reducing eNOS phosphorylation at Ser1177 and inflammation activation via enhancing NFκB pathway,which promotes the susceptibility of atherosclerosis.Exogenous METRNL rescues METRNL deficiency induced endothelial dysfunction.These findings reveal that METRNL is a new endothelial substance not only determining the circulating METRNL level but also regulating endothelial function for vascular health and disease.METRNL is a therapeutic target against endothelial dysfunction and atherosclerosis. | Sili Zheng Zhiyong Li Jie Song Pin Wang Jian Xu Wenjun Hu Yi Shi Qi Qi Zhuwei Miao Yunfeng Guan Chaoyu Miao | 2023 | Acta Pharmaceutica Sinica B2023，13，4： | 2 |
| 19 | Phycocyanin attenuates X-ray-induced pulmonary inflammation via the TLR2-MyD88-NF-κB signaling pathway显示文摘Phycocyanin (PC), a natural algal protein, is reported for having anti-oxidant and antiinfl ammatory properties. We investigated its ability to attenuate lung infl ammation in mice subjected to X-ray radiation. Male C57BL/6 mice were assigned to the control, total body irradiation, PC pretreatment, and PC treatment groups. Mice in the PC pretreatment group were gavaged with 200 mg/kg PC for 7 consecutive days before irradiation, and those in the PC treatment group were gavaged with 200 mg/kg PC for 7 consecutive days after irradiation. Lungs were collected on Day 7 after irradiation exposure. Hematoxylin and eosin staining of mouse lung sections showed considerable infl ammation damage 7 days after irradiation compared with the control lung but a reduction in pathological injury in the PC treatment group. Pretreatment or treatment with PC signifi cantly decreased levels of interleukin-6 and tumor necrosis factor-α in the lung, and also increased the relative mRNA expression of superoxide dismutase and glutathione. In vivo, PC signifi cantly reduced the expression of Toll-like receptor TLR2, myeloid diff erentiation primary response Myd88, and nuclear factor NF-κB, at both the transcriptional and translation level. Taken together, these data indicated that PC attenuated lung infl ammatory damage induced by radiation by blocking the TLR2- MyD88-NF-κB signaling pathway. Therefore, PC could be a protective agent against radiation-induced infl ammatory damage in normal tissues. | LIU Qi LI Wenjun LU Lina LIU Bin DU Zhenning QIN Song | 2019 | Journal of Oceanology and Limnology2019，37，5： | 2 |
| 20 | Tall gastrodis tuber combined with antiepileptic drugs repairs abnormal perfusion foci in focal epilepsy显示文摘One hundred patients with focal epilepsy were recruited for the present study and their seizures controlled with antiepileptic drugs. The patients then orally received a capsule of tall gastrodis tuber powder, a traditional Chinese drug, and underwent single photon emission computed tomography, long-term electroencephalogram, and CT/MRI. Blood drug levels were monitored throughout the study. Before treatment with tall gastrodis tuber, 35 of the 100 cases had abnormal CT/MRI scans; 79 cases had abnormal single photon emission computed tomography images; 86 cases had abnormal electroencephalogram; and a total of 146 abnormal perfusion foci were observed across the 100 subjects. After treatment, the number of patients with normal single photon emission computed tomography images increased by 12; normal electroencephalogram was observed in an additional 27 cases and the number of patients with epileptiform discharge decreased by 29 (34% of 86); the total number of abnormal perfusion foci decreased by 52 (36%) and changes in abnormal foci were visible in 65 patients. These changes indicate that the administration of tall gastrodis tuber in combination with antiepileptic drugs repairs abnormal perfusion foci in patients with focal epilepsy. Our results demonstrate that traditional Chinese drugs can repair abnormal perfusion foci and, as such, are a promising new pathway in the treatment of focal epilepsy. | Weimin Wang Zhenyu Fan Yongqin Zhang Yuxia Yang Yaqing Liu Xiaoli Dang Wenjun Song Yinping Wu Jiang Ye | 2013 | Neural Regeneration Research2013，8，3： | 2 |
