4Learning from berberine: Treating chronic diseases through multiple targets显示文摘Although advances have been made, chemotherapy for chronic, multifactorial diseases such as cancers, Alzheimer's disease, cardiovascular diseases and diabetes is far from satisfactory. Agents with different mechanisms of action are required. The botanic compound berberine(BBR) has been used as an over-the-counter antibacterial for diarrhea in China for many decades. Recent clinical studies have shown that BBR may be therapeutic in various types of chronic diseases. This review addresses BBR's molecular mechanisms of action and clinical efficacy and safety in patients with type 2 diabetes, hyperlipidemia, heart diseases, cancers and inflammation. One of the advantages of BBR is its multiple-target effects in each of these diseases. The therapeutic efficacy of BBR may reflect a synergistic regulation of these targets, resulting in a comprehensive effect against these various chronic disorders. The safety of BBR may be due to its harmonious distribution into those targets. Although the single-target concept is still the principle for drug discovery and research, this review emphasizes the concept of a multiple target strategy, which may be an important approach toward the successful treatment of multifactorial chronic diseases.YAO Jing KONG WeiJia JIANG JianDong 2015Science China(Life Sciences)2015,58,9:32

6The altered expression of inflammation-related microRNAs with microRNA-155 expression correlates with Th17 differentiation in patients with acute coronary syndrome显示文摘MicroRNAs(miRNAs)are a novel class of small,non-coding RNAs that play a significant role in both inflammatory and cardiovascular diseases.Immune cells,especially T helper(Th)cells,are critical in the development of atherosclerosis and the onset of acute coronary syndrome(ACS).To assess whether inflammation-related miRNAs(such as miR-155,146a,21,125a-5p,125b,31)are involved in the imbalance of Th cell subsets in patients with ACS,we measured the expression of related miRNAs in patients with acute myocardial infarction(AMI),unstable angina(UA),stable angina(SA)and chest pain syndrome(CPS);analyzed the relationship between miRNA expression and the frequency of Th cell subsets;and observed the co-expression of miR-155 and IL-17A in peripheral blood mononuclear cells(PBMCs)of patients with ACS.The results showed that the expression of miR-155 in the PBMCs of patients with ACS was decreased by approximately 60%,while the expression of both miR-21 and miR-146a was increased by approximately twofold.The expression patterns of miRNAs in plasma correlated with those in PBMCs,except for miR-21,which was increased by approximately sixfold in the AMI group and showed no significant difference between the UA group and the CPS group.We also found that the expression of miR-155 inversely correlated with the frequency of Th17 cells(r520.896,P,0.01)and that miR-155 was co-expressed with IL-17A in patients with ACS.In conclusion,our study revealed the expression patterns of inflammation-related miRNAs in patients with ACS and found that miR-155 may be associated with Th17 cell differentiation.Rui Yao Yulan Ma Youyou Du Mengyang Liao Huanhuan Li Wei Liang Jing Yuan Zhijun Ma Xian Yu Hong Xiao Yuhua Liao 2011Cellular & Molecular Immunology2011,8,6:32
7Broadband diffusion of terahertz waves by multi-bit coding metasurfaces显示文摘The terahertz region is a special region of the electromagnetic spectrum that incorporates the advantages of both microwaves and infrared light waves.In the past decade,metamaterials with effective medium parameters or gradient phases have been studied to control terahertz waves and realize functional devices.Here,we present a new approach to manipulate terahertz waves by using coding metasurfaces that are composed of digital coding elements.We propose a general coding unit based on a Minkowski closed-loop particle that is capable of generating 1-bit coding(with two phase states of 0 and 180°),2-bit coding(with four phase states of 0,90°,180°,and 270°),and multi-bit coding elements in the terahertz frequencies by using different geometric scales.We show that multi-bit coding metasurfaces have strong abilities to control terahertz waves by designing-specific coding sequences.As an application,we demonstrate a new scattering strategy of terahertz waves—broadband and wide-angle diffusion—using a 2-bit coding metasurface with a special coding design and verify it by both numerical simulations and experiments.The presented method opens a new route to reducing the scattering of terahertz waves.Li-Hua Gao Qiang Cheng Jing Yang Shao-Jie Ma Jie Zhao Shuo Liu Hai-Bing Chen Qiong He Wei-Xiang Jiang Hui-Feng Ma Qi-Ye Wen Lan-Ju Liang Biao-Bing Jin Wei-Wei Liu Lei Zhou Jian-Quan Yao Pei-Heng Wu Tie-Jun Cui 2015Light(Science & Applications)2015,4,1:31
8Interleukin 17-Producing γδ T Cells Increased in Patients with Active Pulmonary Tuberculosis显示文摘Although it has been known that γδ T cells may play an important role in the immune response to infection of Mycobacterium tuberculosis (M. tb), the mechanisms by which the γδ T cells participate in the innate and/or acquired immunity to tuberculosis (TB) have not been full elucidated. In the present study, 27 patients with active pulmonary TB and 16 healthy donors (HD) were performed. We found that proportion of IL-17-producing cells among lymphocyte was similar between TB patients and HD, whereas the proportions of γδ T cells in IL-17-producing cells (59.2%) and IL-17-producing cells in γδ T cells (19.4%) in peripheral blood were markedly increased in TB patients when compared to those in HD (43.9% and 7.7%, respectively). In addition, the proportions of IFN-γ-producing γδ T cells in TB patients were obviously lower than that in HD. Upon re-stimulated with M. tb heat-treated antigen (M. tb-HAg) in vitro, fewer IL-17-producing γδ T cells were generated from HD and TB patients, whereas IFN-γ-producing γδ T cells were increased in TB patients compared to that in HD. Our findings in TB patients and healthy human were consistent with other murine investigation that the IL-17-producing γδ T cells were main source of IL-17 in mouse model of BCG infection, suggesting that γδ T cells might be involved in the formation of tubercular granuloma in pulmonary TB patients, but need further identification.Meiyu Peng Zhaohua Wang Chunyan Yao Lina Jiang Qili Jin Jing Wang Baiqing Li 2008Cellular & Molecular Immunology2008,5,3:28

10Sulforaphane protects liver injury induced by intestinal ischemia reperfusion through Nrf2-ARE pathway显示文摘AIM: To investigate the effect of sulforaphane (SFN) on regulation of NF-E2-related factor-2 (Nrf2)-antiox-idant response element (ARE) pathway in liver injury induced by intestinal ischemia/reperfusion (I/R). METHODS: Rats were divided randomly into four ex-perimental groups: control, SFN control, intestinal I/R and SFN pretreatment groups (n = 8 in each group). The intestinal I/R model was established by clamping the superior mesenteric artery for 1 h and 2 h reperfu-sion. In the SFN pretreatment group, surgery was performed as in the intestinal I/R group, with intraperitoneal administration of 3 mg/kg SFN 1 h before the op-eration. Intestine and liver histology was investigated. Serum levels of aspartate aminotransferase (AST), and alanine aminotransferase (ALT) were measured. Liver tissue superoxide dismutase (SOD), myeloperoxidase (MPO), glutathione (GSH) and glutathione peroxidase (GSH-Px) activity were assayed. The liver transcription factor Nrf2 and heme oxygenase-1 (HO-1) were determined by immunohistochemical analysis and Western blotting analysis.RESULTS: Intestinal I/R induced intestinal and liver injury, characterized by histological changes as well as a signif icant increase in serum AST and ALT levels (AST: 260.13 ± 40.17 U/L vs 186.00 ± 24.21 U/L, P < 0.01; ALT: 139.63 ± 11.35 U/L vs 48.38 ± 10.73 U/L, P < 0.01), all of which were reduced by pretreatment with SFN, respectively (AST: 260.13 ± 40.17 U/L vs 216.63 ± 22.65 U/L, P < 0.05; ALT: 139.63 ± 11.35 U/L vs 97.63 ± 15.56 U/L, P < 0.01). The activity of SOD in the liver tissue decreased after intestinal I/R (P < 0.01), which was enhanced by SFN pretreatment (P < 0.05). In ad-dition, compared with the control group, SFN markedly reduced liver tissue MPO activity (P < 0.05) and elevat-ed liver tissue GSH and GSH-Px activity (P < 0.05, P < 0.05), which was in parallel with the increased level of liver Nrf2 and HO-1 expression.CONCLUSION: SFN pretreatment attenuates liver injury induced by intestinal I/R in rats, attributable to the antioxidant effect through Nrf2-ARE pathway.Zhao, Hai-Dong Zhang, Feng Shen, Gang Li, Yu-Bing Li, Ying-Hua Jing, Hui-Rong Ma, Ling-Fei Yao, Ji-Hong Tian, Xiao-Feng 2010World Journal of Gastroenterology2010,16,24:23
11The TanSat mission: preliminary global observations显示文摘The Chinese global carbon dioxide monitoring satellite (Tan Sat) was launched successfully in December2016 and has completed its on-orbit tests and calibration. Tan Sat aims to measure the atmospheric column-averaged dry air mole fractions of carbon dioxide (XCO_2) with a precision of 4 ppm at the regional scale, and in addition, to derive global and regional CO2fluxes. Progress towards these objectives is reviewed and the first scientific results from Tan Sat measurements are presented. Tan Sat on-orbit tests indicate that the Atmospheric Carbon dioxide Grating Spectrometer is in normal working status and is beginning to produce L1B products. The preliminary Tan Sat XCO_2products have been retrieved by an algorithm and compared to NASA Orbiting Carbon Observatory-2 (OCO-2) measurements during an overlapping observation period. Furthermore, the XCO_2retrievals have been validated against eight groundsite measurement datasets from the Total Carbon Column Observing Network, for which the preliminary conclusion is that Tan Sat has met the precision design requirement, with an average bias of 2.11 ppm.The first scientific observations are presented, namely, the seasonal distributions of XCO_2over land on a global scale.Yi Liu Jing Wang Lu Yao Xi Chen Zhaonan Cai Dongxu Yang Zengshan Yin Songyan Gu Longfei Tian Naimeng Lu Daren Lyu 2018Science Bulletin2018,63,18:23
12A novel gene delivery system targeting cells expressing VEGF receptors显示文摘Two ligand oligopeptides GV1 and GV2 were designed according to the putative binding region of VEGF to its receptors. GV1, GV2 and endosome releasing oligopeptide HA20 were conjugated with poly-L-lysine or protamine and the resulting conjugates could interact with DNA in a noncovalent bond to form a complex. Using pSV2-β-galactosidase as a reporter gene, it has been demonstrated that exogenous gene was transferred into bovine aortic arch-derived endothelial cells (ABAE) andhuman malignant melanoma cell lines (A375) in vitro. In vivo experiments, exogenous gene was transferred into tumor vascular endothelial cells and tumor cells of subcutaneously transplanted human colon cancer LOVO, human malignant melanoma A375 and human hepatoma graft in nude mice. This system could also target gene to intrahepatically transplanted human hepatoma injected via portal vein in nude mice. These results are correlated with theGene delivery system targeting VEGF receptors relevant receptors (flt-1, flk-1/KDR) expression on the targeted cells and tissues.LI JUN MIN JUN SONG HAN YI HUANG PEI KUN TIAN SHU MIN QU MIN YAO HUI QIU JIANG DA FANG WAN JING CHU LUO CHENG XIAO GU JIAN REN GU( National Labomtory for Oncogenes and Related Genes, Shanghai Cancer Institute, Shanghai 200032,China)(National Laboratory of 1999Cell Research1999,9,1:22
13Overexpression of cyclooxygenase-2 in human HepG2, Bel-7402 and SMMC-7721 hepatoma cell lines and mechanism of cyclooxygenase-2 selective inhibitor celecoxib-induced cell growth inhibition and apoptosis显示文摘AIM: To investigate the cyclooxygenase-2 (COX-2)expression level in human HepG2, Bel-7402 and SMMC-7721hepatoma cell lines and the molecular mechanism of COX-2 selective inhibitor celecoxib-induced cell growth inhibition and cell apoptosis.METHODS: Hepatoma cells were cultured and treated with celecoxib. Cell in situ hybridization (ISH) and immunocytochemistry were used to detect COX-2 mRNA and protein expression. Proliferating cell nuclear antigen and phosphorylated Akt were also detected by immunocytochemistry assay. Cell growth rates were assessed by 3-(4, 5-dimethylthiazol-2-yl-2, 5-diphenyltetrazolium (MTT) bromide colorimetric assay. Celecoxibinduced cell apoptosis was measured by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) and flow cytometry (FCM). The phosphorylated Akt and activated fragments of caspase-9, caspase-3 were examined by Western blotting analysis.RESULTS: Increased COX-2 mRNA and protein expression were detected in all three hepatoma cell lines. Celecoxib could significantly inhibit cell growth and the inhibitory effect was in a dose- and time-dependent manner evidenced by MTr assays and morphological changes.The apoptotic index measured by TUNEL increased correspondingly with the increased concentration of celecoxib and the reaction time. With 50 μmol/L celecoxib treatment for 24 h, the apoptotic index of HepG2, BEL-7402and SMMC-7721 cells was 25.01±3.08%, 26.40±3.05%,and 30.60±2.89%, respectively. Western blotting analysis showed remarkable activation of caspase-9, caspase-3and dephosphorylation of Akt (Thr308). Immunocytochemistry also showed the reduction of PCNA expression and phosphorylation Akt (Thr308) after treatment with celecoxib.CONCLUSION: COX-2 mRNA and protein overexpression in HepG2, Bel-7402 and SMMC-7721 cell lines correlate with the increased cell growth rate. Celecoxib can inhibit proliferation and induce apoptosis of hepatoma cell strains in a dose- and time-dependent manner.Ning-Bo Liu Tao Peng Chao Pan Yu-Yu Yao Bo Shen Jing Leng 2005World Journal of Gastroenterology2005,11,40:20

15Immunogenicity noninferiority study of 2 doses and 3 doses of an Escherichia coli-produced HPV bivalent vaccine in girls vs.3 doses in young women显示文摘A new HPV-16/18 bivalent vaccine expressed by the Escherichia coli has been proven to be efficacious in adult women.A randomized,immunogenicity noninferiority study of this candidate vaccine was conducted in December 2015 in China.Girls aged 9–14 years were randomized to receive 2 doses at months 0 and 6(n=301)or 3 doses at months 0,1 and 6(n=304).Girls aged 15–17 years(n=149)and women aged 18–26 years(n=225)received 3 doses.The objectives included noninferiority analysis of the IgG geometric mean concentration(GMC)ratio(95%CI,lower bound>0.5)to HPV-16 and HPV-18 at month 7 in girls compared with women.In the per-protocol set,the GMC ratio of IgG was noninferior for girls aged 9–17 years receiving 3 doses compared with women(1.76(95%CI,1.56,1.99)for HPV-16 and 1.93(95%CI,1.69,2.21)for HPV-18)and noninferior for girls aged 9–14 years receiving 2 doses compared with women(1.45(95%CI,1.25,1.62)for HPV-16 and 1.17(95%CI,1.02,1.33)for HPV-18).Noninferiority was also demonstrated for neutralizing antibodies.The immunogenicity of the HPV vaccine in girls receiving 3 or 2 doses was noninferior compared with that in young adult women.Yue-Mei Hu Meng Guo Chang-Gui Li Kai Chu Wen-Gang He Jing Zhang Jian-Xiang Gu Juan Li Hui Zhao Xiang-Hong Wu Bi-Zhen Lin Zhi-Jie Lin Xing-Mei Yao Ya-Fei Li Fei-Xue Wei Yue Huang Ying-Ying Su Feng-Cai Zhu Shou-Jie Huang Hui-Rong Pan Ting Wu Jun Zhang Ning-Shao Xia 2020Science China(Life Sciences)2020,63,4:19
16An elastic-viscous-plastic model for overconsolidated clays显示文摘The influences of time on clays are discussed first,and the concept of the instant normal compression line is proposed by analyzing the existing theories and experimental results.Based on the creep law,the relationship between the aging time and the overconsolidation parameter is built.With the reloading equation of the UH model(unified hardening model for overconsolidated clays) used to calculate the instant compression deformation,a one-dimensional stress-strain-time relationship is proposed.Furthermore,the evolution of this relationship is analyzed,and the characteristic rate that is a function of the overconsolidation parameter is defined.Then a three-dimensional elastic-viscous-plastic constitutive model is suggested by incorporating equivalent time into the current yield function of the UH model.The new model can describe not only creep,rate effect and other viscous phenomena,but also shear dilatancy,strain softening and other behaviors of overconsolidated clays.Besides,compared with the modified Cam-clay model it requires only one additional parameter(the coefficient of secondary compression) to consider the creep law.Finally,because the proposed model can be changed into the UH model under instantaneous loading,the elastic-plastic and elastic-viscous-plastic frameworks are unified.YAO YangPing KONG LingMing HU Jing 2013Science China(Technological Sciences)2013,56,2:19
17Combined acoustic radiation force impulse, aminotransferase to platelet ratio index and Forns index assessment for hepatic fibrosis grading in hepatitis B显示文摘AIM: To investigate the combined diagnostic accuracy of acoustic radiation force impulse(ARFI), aspartate aminotransferase to platelet ratio index(APRI) and Forns index for a non-invasive assessment of liver fibrosis in patients with chronic hepatitis B(CHB). METHODS: In this prospective study, 206 patients had CHB with liver fibrosis stages F0-F4 classified by METAVIR and 40 were healthy volunteers were measured by ARFI, APRI and Forns index separately or combined as indicated. RESULTS: ARFI, APRI or Forns index demonstrated a significant correlation with the histological stage(all P < 0.001). According to the AUROC of ARFI and APRI for evaluating fibrotic stages more than F2, ARFI showed an enhanced diagnostic accuracy than APRI(P < 0.05). The combined measurement of ARFI and APRI exhibited better accuracy than ARFI alone when evaluating ≥ F2 fibrotic stage(Z = 2.77, P = 0.006). Combination of ARFI, APRI and Forns index did not obviously improve the diagnostic accuracy compared to the combination of ARFI and APRI(Z = 0.958, P = 0.338). CONCLUSION: ARFI + APRI showed enhanced diagnostic accuracy than ARFI or APRI alone for significant liver fibrosis and ARFI + APRI + Forns index shows the same effect with ARFI + APRI.Chang-Feng Dong Jia Xiao Ling-Bo Shan Han-Ying Li Yong-Jia Xiong Gui-Lin Yang Jing Liu Si-Min Yao Sha-Xi Li Xiao-Hua Le Jing Yuan Bo-Ping Zhou George L Tipoe Ying-Xia Liu 2016World Journal of Hepatology2016,8,14:18
18Nutrients concentration and changes in decade-scale in the central Bohai Sea显示文摘The nutrients contents and distributions are discussed briefly, based on the data obtained in 1998~1999. Besides explanation of the results,a 20 a time series data of nutrients and biological parameters for central Bohai Sea are reviewed. It is found that both concentration and relative content of nutrients have been changed dramatically. The increase of nitrogen and decrease of phosphate and silicate led to the dramatically increase of N/P ratio and the decrease of Si/N ratio. The situation of nitrogen limiting in central Bohai Sea is gradually changing to that of relative lack of phosphate and silicate. The decrease of the Huanghe River input to the Bohai Sea may be responsible for this change. These in turn may limit the growth of diatom and thus promote the development of pyrrophyta if other conditions (e.g. temperature and hydrodynamics) are suitable. We conclude that this may be the major inducement factor of pyrrophyta red tide in the Bohai Sea.Yu Zhigang 1,Mi Tiezhu 1,Yao Qingzhen 1,Xie Baodong 1,Zhang Jing 11 .CollegeofChemistryandChemicalEngineering ,OceanUniversityofQingdao ,Qingdao 2 6 6 0 0 3 ,China 2001Acta Oceanologica Sinica2001,20,1:18
19Human monoclonal antibodies block the binding of SARS-CoV-2 spike protein to angiotensin converting enzyme 2 receptor显示文摘According to the World Health Organization(WHO)newly updated situation report on March 18th,2020,the coronavirus disease 2019(COVID-19)pandemic has confirmed 191,127 cases and claimed 7807 deaths worldwide.1 The etiological agent of COVID-19 has been identified as a novel coronavirus,the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),belonging to Sarbecovirus subgenus(genus Betacoronavirus,family Coronaviridae)and showing 79.6 and 96.2%sequence identity in nucleotide to SARS-CoV and a bat coronavirus(BatCoV RaTG13),respectively.2–4 Like SARS-CoV infection,a substantial fraction of COVID-19 patients exhibits severe respiratory symptoms and has to be hospitalized in intensive care unit.5–8 Although the mortality rate of COVID-19 is significantly lower than that of SARS-CoV infection,SARS-CoV-2 shows much higher human-to-human transmission rate,rapidly leading to a global pandemic declared by WHO on March 11th,2020.Xiangyu Chen Ren Li Zhiwei Pan Chunfang Qian Yang Yang Renrong You Jing Zhao Pinghuang Liu Leiqiong Gao Zhirong Li Qizhao Huang Lifan Xu Jianfang Tang Qin Tian Wei Yao Li Hu Xiaofeng Yan Xinyuan Zhou Yuzhang Wu Kai Deng Zheng Zhang Zhaohui Qian Yaokai Chen Lilin Ye 2020Cellular & Molecular Immunology2020,17,6:17
20Microwave Exposure Impairs Synaptic Plasticity in the Rat Hippocampus and PC12 Cells through Over-activation of the NMDA Receptor Signaling Pathway显示文摘Objective The aim of this study is to investigate whether microwave exposure would affect the N-methyl-D-aspartate receptor(NMDAR) signaling pathway to establish whether this plays a role in synaptic plasticity impairment. Methods 48 male Wistar rats were exposed to 30 m W/cm2 microwave for 10 min every other day for three times. Hippocampal structure was observed through H&E staining and transmission electron microscope. PC12 cells were exposed to 30 m W/cm2 microwave for 5 min and the synapse morphology was visualized with scanning electron microscope and atomic force microscope. The release of amino acid neurotransmitters and calcium influx were detected. The expressions of several key NMDAR signaling molecules were evaluated. Results Microwave exposure caused injury in rat hippocampal structure and PC12 cells, especially the structure and quantity of synapses. The ratio of glutamic acid and gamma-aminobutyric acid neurotransmitters was increased and the intracellular calcium level was elevated in PC12 cells. A significant change in NMDAR subunits(NR1, NR2 A, and NR2B) and related signaling molecules(Ca2+/calmodulin-dependent kinase II gamma and phosphorylated c AMP-response element binding protein) were examined. Conclusion 30 m W/cm2 microwave exposure resulted in alterations of synaptic structure, amino acid neurotransmitter release and calcium influx. NMDAR signaling molecules were closely associated with impaired synaptic plasticity.XIONG Lu SUN Cheng Feng ZHANG Jing GAO Ya Bing WANG Li Feng ZUO Hong Yan WANG Shui Ming ZHOU Hong Mei XU Xin Ping DONG Ji YAO Bin Wei ZHAO Li PENG Rui Yun 2015Biomedical and Environmental Sciences2015,28,1:16
