| 1 | Ligustrazine monomer against cerebral ischemia/reperfusion injury显示文摘Ligustrazine(2,3,5,6-tetramethylpyrazine) is a major active ingredient of the Szechwan lovage rhizome and is extensively used in treatment of ischemic cerebrovascular disease.The mechanism of action of ligustrazine use against ischemic cerebrovascular diseases remains unclear at present.This study summarizes its protective effect,the optimum time window of administration,and the most effective mode of administration for clinical treatment of cerebral ischemia/reperfusion injury.We examine the effects of ligustrazine on suppressing excitatory amino acid release,promoting migration,differentiation and proliferation of endogenous neural stem cells.We also looked at its effects on angiogenesis and how it inhibits thrombosis,the inflammatory response,and apoptosis after cerebral ischemia.We consider that ligustrazine gives noticeable protection from cerebral ischemia/reperfusion injury.The time window of ligustrazine administration is limited.The protective effect and time window of a series of derivative monomers of ligustrazine such as 2-[(1,1-dimethylethyl)oxidoimino]methyl]-3,5,6-trimethylpyrazine,CXC137 and CXC195 after cerebral ischemia were better than ligustrazine. | Hai-jun Gao Peng-fei Liu Pei-wen Li Zhuo-yan Huang Feng-bo Yu Ting Lei Yong Chen Ye Cheng Qing-chun Mu Hai-yan Huang | 2015 | Neural Regeneration Research2015，10，5： | 48 |
| 2 | Attention mechanisms in computer vision:A survey显示文摘Humans can naturally and effectively find salient regions in complex scenes.Motivated by this observation,attention mechanisms were introduced into computer vision with the aim of imitating this aspect of the human visual system.Such an attention mechanism can be regarded as a dynamic weight adjustment process based on features of the input image.Attention mechanisms have achieved great success in many visual tasks,including image classification,object detection,semantic segmentation,video understanding,image generation,3D vision,multimodal tasks,and self-supervised learning.In this survey,we provide a comprehensive review of various attention mechanisms in computer vision and categorize them according to approach,such as channel attention,spatial attention,temporal attention,and branch attention;a related repository http://gffzz188fe103f8f1460as6v0no9cbvxxk6q69.ffgz.tsg.suse.edu.cn/MenghaoG uo/Awesome-Vision-Attentions is dedicated to collecting related work.We also suggest future directions for attention mechanism research. | Meng-Hao Guo Tian-Xing Xu Jiang-Jiang Liu Zheng-Ning Liu Peng-Tao Jiang Tai-Jiang Mu Song-Hai Zhang Ralph R.Martin Ming-Ming Cheng Shi-Min Hu | 2022 | Computational Visual Media2022，8，3： | 27 |

| 6 | Effect of blueberry on hepatic and immunological functions in mice显示文摘BACKGROUND:Conventional drugs used in the treatment and prevention of liver diseases often have side effects,therefore research into natural substances are of significance.This study examined the effects of blueberry on liver protection and cellular immune functions. METHODS:To determine the effects of blueberry on liver protective function,male mice were orally administered blueberry(0.6 g/10 g)or normal saline for 21 days.Hepatic RNA was extracted by Trizol reagent,and the expression of Nrf2,HO-1,and Nqo1 was determined by real-time RT- PCR.Superoxide dismutase(SOD)and malondialdehyde (MDA)in liver homogenate were determined,and liver index was measured.To assess the effects of blueberry on cellular immune function,male mice received blueberry(0.4,0.6,or 0.8 g/10 g)for 35 days,and the percentages of CD3 + ,CD4 + ,and CD8 + T lymphocyte subgroups in peripheral blood were detected by flow cytometry,the index of the thymus and spleen was measured,and lymphocyte proliferation in the spleen was determined by MTT assay. RESULTS:Blueberry treatment significantly increased the expression of Nrf2,HO-1,and Nqo1,the important antioxidant components in the liver.Hepatic SOD in the blueberry group was higher and MDA was lower than that in the control group (P<0.05).Blueberry also increased the index of the spleen and enhanced the proliferation of lymphocytes of the spleen (P<0.05).The percentages of the CD3 + and CD4 + T lymphocyte subsets and the CD4 + /CD8 + ratio were also increased by blueberry(P<0.05). CONCLUSIONS:Blueberry induces expression of Nrf2,HO-1,and Nqo1,which can protect hepatocytes from oxidative stress. In addition,blueberry can modulate T-cell function in mice. | Wang, Yu-Ping Cheng, Ming-Liang Zhang, Bao-Fang Mu, Mao Zhou, Ming-Yu Wu, Jun Li, Cheng-Xiu | 2010 | Hepatobiliary & Pancreatic Diseases International2010，9，2： | 15 |
| 7 | Hepatitis B surface antigen clearance in inactive hepatitis B surface antigen carriers treated with peginterferon alfa-2a显示文摘AIM: To examine the association between interferon(IFN) therapy and loss of hepatitis B surface antigen(HBs Ag) in inactive HBs Ag carriers. METHODS: This was a retrospective cohort study in inactive HBs Ag carriers, who were treatment-naive, with a serum HBs Ag level < 100 IU/m L and an undetectable hepatitis B virus(HBV) DNA level(< 100 IU/m L). All the 20 treated patients received subcutaneous PEG-IFN alfa-2a 180 μg/wk for 72 wk and were then followed for 24 wk. There were 40 untreated controls matched with 96 wk of observation. Serum HBs Ag, HBV DNA, and alanine aminotransferases were monitored every 3 mo in the treatment group and every 3-6 mo in the control group. RESULTS: Thirteen(65.0%) of 20 treated patients achieved HBs Ag loss, 12 of whom achieved HBs Ag seroconversion. Mean HBs Ag level in treated patients decreased to 6.69 ± 13.04 IU/m L after 24 wk of treatment from a baseline level of 26.22 ± 33.00 IU/m L. Serum HBV DNA level remained undetectable(< 100 IU/m L) in all treated patients during the study. HBs Ag level of the control group decreased from 25.72 ± 25.58 IU/m L at baseline to 17.11 ± 21.62 IU/m L at week 96(P = 0.108). In the control group, no patient experienced HBs Ag loss/seroconversion, and two(5.0%) developed HBV reactivation.CONCLUSION: IFN treatment results in HBs Ag loss and seroconversion in a considerable proportion of inactive HBs Ag carriers with low HBs Ag concentrations. | Ming-Hui Li Yao Xie Lu Zhang Yao Lu Ge Shen Shu-Ling Wu Min Chang Cai-Qin Mu Lei-Ping Hu Wen-Hao Hua Shu-Jing Song Shu-Feng Zhang Jun Cheng Dao-Zhen Xu | 2016 | World Journal of Hepatology2016，8，15： | 15 |
| 8 | Molecular Characterization of Drug-Resistant Beijing Family Isolates of Mycobacterium Tuberculosis from Tianjin,China显示文摘Objective Tuberculosis remains a severe public health issue,and the Beijing family of mycobacterium tuberculosis(M. tuberculosis) is widespread in East Asia,especially in some areas in China,like Beijing and Tianjin.This study aimed at determining the mutation patterns of drug-resistant Beijing strains of M.tuberculosis isolated from Tianjin,China.Methods A total of 822 M.tuberculosis isolates were screened for drug resistance by an absolute concentration method and the genotype was identified by PCR.169 drug-resistant isolates of the Beijing family were analyzed for the potential mutations in the rpoB, katG,inhA promoter region and in rpsL,rrs and embB genes,which are associated with resistance to rifampin(RFP),isoniazid (INH),streptomycin(SM) and ethambutol(EMB) respectively by PCR and DNA sequencing.Results Fifty-eight out of 63 RFP-resistant isolates were found to carry the mutations within the 81-bp RFP resistance determining region(RRDR) of the rpoB gene and the most frequent mutations occurred at codon 531(44.4%),526(28.6%),and 516(7.9%) respectively.16 mutation patterns affecting 12 different codons around the RRDR of rpoB were found.Of 116 INH-resistant isolates,56(48.3%) had the mutation of katG 315(AGC→ACC)(Ser→Thr),3(2.6%) carried S315N(AGC→AAC) and 27(16.0%) had the mutation of inhA-15A→T.84 out of 122 SM-resistant isolates(68.9%) displayed mutations at the codons 43 or 88 with AAG→AGG(Lys→Arg) of the rpsL gene and 22(18.0%) with the mutations at positions 513A→C,516C→T or 905 A→G in the rrs gene.Of 34 EMB-resistant isolates,6 had mutation with M306V(ATG→GTG),3 with M306I(ATG→ATT),1 with M306I(ATG→ATA),1 with D328Y(GAT→TAT),1 with V348L(GTC→CTC),and 1 with G406S(GGC→AGC) in the embB gene.Conclusion These novel findings extended our understanding of resistance-related mutations in the Beijing strains of M.tuberculosis and may provide a scientific basis for development of new strategies for diagnosis and control of tuberculosis in China and other countries where Beijing strains are prevalent. | GUI-LIAN LI DE-FU ZHAO TONG XIE HAN-FANG JU CHENG MU HUI ZHAO XIE-XIU WANG | 2010 | Biomedical and Environmental Sciences2010，23，3： | 14 |

| 11 | Effect of Danshao Huaxian capsule on Gremlin and bone morphogenetic protein-7 expression in hepatic fibrosis in rats显示文摘AIM:To observe the effect of Danshao Huaxian capsule(DHC)on the expression of Gremlin and bone morphogenetic protein-7(BMP-7)in the liver of hepatic fibrosis rats.METHODS:A total of 75 male Wistar rats were randomly divided into a normal control group(A),a CCl4-induced hepatic fibrosis model group(B),a natural recovery group(C),a low-dose DHC-treated group(D),and a high-dose DHC-treated group(E),with 15 rats in each group.Liver fibrosis was induced by subcutaneous injections of carbon tetrachloride(CCl4)and a highlipid/low-protein diet for 8 wk,except for the rats in group A.Then,the rats in the two DHC-treated groups were administered 0.5 and 1.0 g/kg DHC by gastrogavage once per day for 8 successive weeks,respectively.By the end of the experiment,the level of transforming growth factorβ1(TGF-β1)in the liver homogenate was determined by an enzyme-linked immunosorbent assay.The mRNA and protein expression of Gremlin and BMP-7 in the liver tissue was determined by reversetranscription polymerase chain reaction,an immunohistochemical assay,and Western blot analysis.RESULTS:Compared with group A,the level of TGF-β1and the mRNA and protein expression of Gremlin were significantly higher in group B(TGF-β1:736.30±24.40μg/g vs 284.20±18.32μg/g,P<0.01;mRNA of Gremlin:80.40±5.46 vs 49.83±4.20,P<0.01;positive protein expression rate of Gremlin:38.46%±1.70%vs 3.83%±0.88%,P<0.01;relative protein expression of Gremlin:2.81±0.24 vs 0.24±0.06,P<0.01),and the mRNA and protein expression of BMP-7was significantly lower in group B(mRNA:54.00±4.34vs 93.99±7.03,P<0.01;positive protein expression rate:28.97%±3.14%vs 58.29%±6.02,P<0.01;relative protein expression:0.48±0.31 vs 1.05±0.12,P<0.01).Compared with groups B and C,the degree of hepatic fibrosis was significantly improved,and the level of TGF-β1 and the mRNA and protein expression of Gremlin were significantly lowered in the two DHCtreated groups(TGF-β1:523.14±21.29μg/g,441.86±23.18μg/g vs 736.30±24.40μg/g,651.13±15.75μg/g,P<0.01;mRNA of Gremlin:64.86±2.83,55.82±5.39 vs 80.40±5.46,70.37±4.01,P<0.01;positive protein expression rate of Gremlin:20.78%±1.60%,17.43%±2.02%vs 38.46%±1.70%,29.50%±2.64%,P<0.01;relative protein expression of Gremlin:1.95±0.26,1.65±0.20 vs 2.81±0.24,2.22±0.63,P<0.01),and the mRNA and protein expression of BMP-7 was higher in the two DHC-treated groups(mRNA:73.52±4.56,81.78±5.38 vs 54.00±4.34,62.28±4.51,P<0.01;positive protein expression rate:41.44%±4.77%,47.49%±4.59%vs28.97%±3.14%,35.85%±3.50%,P<0.01;relative protein expression:0.71±0.06,0.81±0.07 vs 0.48±CONCLUSION:The therapeutic mechanism of DHC forhepatic fibrosis in rats may be associated with inhibitionof the expression of Gremlin and up-regulation of the expression of BMP-7. | Xue-Ke Zhao Ming-Liang Cheng Rong-Min Wu Yu-Mei Yao Mao Mu Juan-Juan Zhu Bao-Fang Zhang Ming-Yu Zhou | 2014 | World Journal of Gastroenterology2014，20，40： | 11 |
| 12 | Single-Atom Catalysts for Electrochemical Hydrogen Evolution Reaction: Recent Advances and Future Perspectives显示文摘Hydrogen,a renewable and outstanding energy carrier with zero carbon dioxide emission,is regarded as the best alternative to fossil fuels.The most preferred route to large-scale production of hydrogen is by water electrolysis from the intermittent sources(e.g.,wind,solar,hydro,and tidal energy).However,the efficiency of water electrolysis is very much dependent on the activity of electrocatalysts.Thus,designing high-effective,stable,and cheap materials for hydrogen evolution reaction(HER)could have a substantial impact on renewable energy technologies.Recently,single-atom catalysts(SACs)have emerged as a new frontier in catalysis science,because SACs have maximum atom-utilization efficiency and excellent catalytic reaction activity.Various synthesis methods and analytical techniques have been adopted to prepare and characterize these SACs.In this review,we discuss recent progress on SACs synthesis,characterization methods,and their catalytic applications.Particularly,we highlight their unique electrochemical characteristics toward HER.Finally,the current key challenges in SACs for HER are pointed out and some potential directions are proposed as well. | Zonghua Pu Ibrahim Saana Amiinu Ruilin Cheng Pengyan Wang Chengtian Zhang Shichun Mu Weiyue Zhao Fengmei Su Gaixia Zhang Shijun Liao Shuhui Sun | 2020 | Nano-Micro Letters2020，12，2： | 10 |
| 13 | Yiguanjian decoction enhances fetal liver stem/progenitor cell-mediated repair of liver cirrhosis through regulation of macrophage activation state显示文摘AIM To investigate whether Yiguanjian decoction(YGJ) has an anti-liver cirrhotic effect and whether it regulates hepatic stem cell differentiation.METHODS A rat model of liver cirrhosis was established via subcutaneous injection of carbon tetrachloride(CCl4) for8 wk. From the beginning of the ninth week, the rats received 2-acetylaminofluorene(2-AAF) by oral gavage and a DLK-1+ fetal liver stem/progenitor cell(FLSPC)transplant or an FLSPC transplant in combination with YGJ treatment for 4 wk. In vitro, lipopolysaccharide(LPS)-activated macrophages were co-cultured with WB-F344 cells, and the differentiation of WB-F344 cells was observed in the presence and absence of YGJ treatment.RESULTS FLSPC transplantation improved liver function and histopathology, and inhibited the activation of the noncanonical Wnt signaling pathway, while activating the canonical Wnt signaling pathway. YGJ enhanced the therapeutic effects of FLSPCs and also promoted the liver regeneration differentiation of FLSPCs into hepatocytes.In vitro, LPS-activated macrophages promoted the differentiation of WB-F344 cells into myofibroblasts, and the canonical Wnt signaling was inhibited while the noncanonical Wnt signaling was activated in WB-F344 cells.YGJ suppressed the activation of macrophages and then inhibited non-canonical Wnt signaling and promoted canonical Wnt signaling.CONCLUSION YGJ enhances FLSPC-mediated repair of liver cirrhosis through regulation of macrophage activation state, and YGJ in combination with stem cell transplantation may be a suitable treatment for end-stage liver cirrhosis. | Ying Xu Wei-Wei Fan Wen Xu Shi-Li Jiang Gao-Feng Chen Cheng Liu Jia-Mei Chen Hua Zhang Ping Liu Yong-Ping Mu | 2018 | World Journal of Gastroenterology2018，24，42： | 10 |

| 18 | Sini powder ameliorates the inflammatory response in rats with stress-induced non-alcoholic fatty liver disease by inhibiting the nuclear factor kappa-B/pyrin domain-containing protein 3 pathway显示文摘OBJECTIVE: To evaluate the effectiveness of Sini powder for the treatment of non-alcoholic fatty liver disease(NAFLD) in rats and the molecular mechanisms involved.METHODS: A rat model of stress-induced NAFLD was established by a combination of long-term tethering and feeding of a high-fat, high-calorie diet. These rats were then intragastrically administered with either simvastatin, Sini powder, or vehicle for 1 week. The body mass and field test scores for each group were recorded weekly. Serum aspartate aminotransferase and alanine aminotransferase activities, and triglyceride, total cholesterol,and free fatty acid concentrations were measured.Liver tissue histopathology was examined on hematoxylin and eosin-stained paraffin sections and oil red O-stained frozen sections. The hepatic m RNA expression of nuclear factor kappa-B(NF-κB),NOD-, LRR-, and pyrin domain-containing protein 3(NLRP3), apoptosis-associated speck-like protein containing CARD(ASC), and caspase-1 were measured by reverse transcription-polymerase chain reaction(RT-PCR). The hepatic protein concentrations of NF-κB and NLRP3, ASC, caspase-1, interleukin-1β(IL-1β), interleukin-6(IL-6), and the serum concentrations of IL-1β and IL-6 were measured by enzyme-linked immunosorbent assay.RESULTS: Compared with the Blank group, rats in the Compound model group showed significant pathologic manifestations of NAFLD, and the expression of NF-κB, NLRP3, ASC, caspase-1, IL-1βand IL-6 were significantly higher(all P < 0.01). Both simvastatin and Sini powder significantly ameliorated the NAFLD pathology and the abnormal expression of NF-κB, NLRP3, ASC, caspase-1, IL-1β, and IL-6(all P < 0.01).CONCLUSION: Sini powder inhibits the inflamma-tory response in rats with NAFLD, which is mediated by NF-κB/NLRP3, IL-1β, and IL-6, reduces the effects of psychological stress, and improves lipid metabolism. Therefore, Sini powder may be effective for the treatment of stress-related NAFLD through multiple mechanisms. | Mu Jie Cheng Fafeng Wang Qingguo Wang Xueqian Zhu Wenxiang Ma Chongyang Yin Xiangjun Ren Beida Lian Yajun Du Xin Zhang Haixia Liu Shuling Zhang Shuang | 2020 | Journal of Traditional Chinese Medicine2020，40，2： | 9 |
| 19 | Defects enriched hollow porous Co-N-doped carbons embedded with ultrafine CoFe/Co nanoparticles as bifunctional oxygen electrocatalyst for rechargeable flexible solid zinc-air batteries显示文摘The construction and design of highly efficient and inexpensive bifunctional oxygen electrocatalysts substitute for noble-metal-based catalysts is highly desirable for the development of rechargeable Zn-air battery(ZAB).In this work,a bifunctional oxygen electrocatalysts of based on ultrafine CoFe alloy(4-5 nm)dispersed in defects enriched hollow porous Co-N-doped carbons,made by annealing SiO2 coated zeolitic imidazolate framework-67(ZIF-67)encapsulated Fe ions.The hollow porous structure not only exposed the active sites inside ZIF-67,but also provided efficient charge and mass transfer.The strong synergetic coupling among high-density CoFe alloys and Co-N_(x) sites in Co,N-doped carbon species ensures high oxygen reduction reaction(ORR)and oxygen evolution reaction(OER)activity.First-principles simulations reveal that the synergistic promotion effect between CoFe alloy and Co-N site effectively reduced the formation energy of from O^(*)to OH^(*).The optimized CoFe-Co@PNC exhibits outstanding electrocatalytic stability and activity with the overpotential of only 320 mV for OER at 10 mA·cm^(−2) and the half-wave potential of 0.887 V for ORR,outperforming that of most recent reported bifunctional electrocatalysts.A rechargeable ZAB constructed with CoFe-Co@PNC as the air cathode displays long-term cyclability for over 200 h and high power density(152.8 mW·cm^(−2)).Flexible solid-state ZAB with our CoFe-Co@PNC as the air cathode possesses a high open circuit potential(OCP)up to 1.46 V as well as good bending flexibility.This universal structure design provides an attractive and instructive model for the application of nanomaterials derived from MOF in the field of sustainable flexible energy applications device. | Zhao Lei Yangyang Tan Zeyi Zhang Wei Wu Niancai Cheng Runzhe Chen Shichun Mu Xueliang Sun | 2021 | Nano Research2021，14，3： | 9 |
