4Does Helicobacter pylori infection play a role in iron deficiency anemia? A meta-analysis显示文摘AIM:To perform a meta-analysis of observational studies and randomized controlled trials(RCTs)on the association between Helicobacter pylori(H.pylori)and iron deficiency anemia(IDA).METHODS:A defined search strategy was used to search Medline,Embase,the Cochrane Library,Clinical Trials,Cochrane Central Register of Controlled Trials,Premedline and Healthstar.Odds ratio(OR)was used to evaluate observational epidemiology studies,and weighted mean difference(WMD)was used to demonstrate the difference between control and intervention groups.RESULTS:Fifteen observational studies and 5 RCTs were identified and used for calculation.The pooled OR for observational studies was 2.22(95%CI:1.52-3.24,P<0.0001).The WMD for hemoglobin(HB) was 4.06 g/L(95%CI:-2.57-10.69,P=0.01),and the WMD for serum ferritin(SF)was 9.47μg/L(95%CI:-0.50-19.43,P<0.0001).Results were heterogeneous for all comparisons.CONCLUSION:This meta-analysis on observational studies suggests an association between H.pylori and IDA.In RCTs,eradication of H.pylori can improve HB and SF levels but not significantly.Qu, Xin-Hua Huang, Xiao-Lu Xiong, Ping Zhu, Cui-Ying Huang, You-Liang Lu, Lun-Gen Sun, Xu Rong, Lan Zhong, Liang Sun, Da-Yu Lin, Hai Cai, Ming-Ci Chen, Zhi-Wei Hu, Bing Wu, Lian-Ming Jiang, Yi-Bin Yan, Wei-Li 2010World Journal of Gastroenterology2010,16,7:34
5Impact of postoperative omega-3 fatty acid-supplemented parenteral nutrition on clinical outcomes and immunomodulations in colorectal cancer patients显示文摘AIM: To investigate the effect of omega-3 fatty acid parenteral supplementation postoperatively on clinical outcomes and immunomodulation in colorectal cancer patients. METHODS: Forty-two patients undergoing radical colorectal cancer resection with an indication for total parenteral nutrition postoperatively were enrolled in this prospective, double-blind, randomized, controlled study. Patients received total parenteral nutrition supplemented with either soybean oil (LCT; Intralipid, Fresenius-Kabi, SO group, n = 21) or a combination of omega-3 fish oil and soybean oil (LCT:fish oil = 5:1, fish oil; Omegaven, Fresenius-Kabi, FO group, n = 21), up to a total of 1.2 g lipid/kg per day for 7 d postoperatively. A same volume calorie and nitrogen was administrated. Routine blood test, biochemistry, systemic levels of IL-6 and TNF-α, percentage of CD3+, CD4+, and CD8+ lymphocytes were evaluated preoperatively and on postoperative d 1 and 8. Patient outcome was evaluated considering mortality during the hospital stay, length of postoperative hospital stay, and occurrence of infectious complications. RESULTS: Both lipid regimens were well tolerated. No differences between the two groups were noticed in demographics, baseline blood test, biochemistry, serum levels of IL-6 and TNF-α, percentage of CD4+, CD8+ lymphocytes, and ratios of CD4+/CD8+. Compared with those on postoperative d 1, serum IL-6 levels onpostoperative d 8 were significantly depressed in the FO group than in the reference group (-44.43 ± 30.53 vs -8.39 ± 69.08, P = 0.039). Simultaneously, the ratios of CD4+/CD8+ were significantly increased in the FO group (0.92 ± 0.62 vs 0.25 ± 1.22, P = 0.035). In addition, depression of serum TNF-α levels (-0.82 ± 2.71 vs 0.27 ± 1.67, P = 0.125) and elevation of CD3+ and CD4+ lymphocyte percentage (12.85 ± 11.61 vs 3.84 ± 19.62, P = 0.081, 17.80 ± 10.86 vs 9.66 ± 17.55, P = 0.084, respectively) were higher in the FO group than in the reference group. Patients in the FO group trended to need a shorter postoperative hospital stay (17.45 ± 4.80 d vs 19.62 ± 5.59 d, P = 0.19). No statistically significant difference was found when stratified to mortality and occurrence of infectious complications. CONCLUSION: Postoperative supplementation of omega-3 fatty acids may have a favorable effect on the outcomes in colorectal cancer patients undergoing radical resection by lowering the magnitude of inflammatory responses and modulating the immune response.Bin Liang, Shan Wang, Ying-Jiang Ye, Xiao-Dong Yang, You-Li Wang, Jun Qu, Qi-Wei Xie, Mu-Jun Yin, Division of Surgical Oncology and Division of Gastroenterological Surgery, Peking University People’s Hospital, Beijing 100044, China Author contributions: Liang B and Wang S contributed equally to this work Liang B and Wang S designed the research Liang B, Ye YJ, Yang XD, Wang YL, Qu J, Xie QW, Yin MJ performed the research and collected the data Wang S and Ye YJ supervised the research Liang B and Ye YJ analyzed the data Liang B wrote the paper and revised the manuscript. 2008World Journal of Gastroenterology2008,14,15:31

8A long-term Global LAnd Surface Satellite(GLASS)data-set for environmental studies显示文摘Recently,five Global LAnd Surface Satellite(GLASS)products have been released:leaf area index(LAI),shortwave broadband albedo,longwave broadband emissivity,incident short radiation,and photosynthetically active radiation(PAR).The first three products cover the years 19822012(LAI)and 19812010(albedo and emissivity)at 15 km and 8-day resolutions,and the last two radiation products span the period 20082010 at 5 km and 3-h resolutions.These products have been evaluated and validated,and the preliminary results indicate that they are of higher quality and accuracy than the existing products.In particular,the first three products have much longer time series,and are therefore highly suitable for various environmental studies.This paper outlines the algorithms,product characteristics,preliminary validation results,potential applications and some examples of initial analysis of these products.Shunlin Liang Xiang Zhao Suhong Liu Wenping Yuan Xiao Cheng Zhiqiang Xiao Xiaotong Zhang Qiang Liu Jie Cheng Hairong Tang Yonghua Qu Yancheng Bo Ying Qu Huazhong Ren Kai Yu John Townshend 2013International Journal of Digital Earth2013,6,S01:16
9Method for enhancing visibility of hazy images based on polarimetric imaging显示文摘A novel polarimetric dehazing method is proposed based on three linear polarization images(0°,45°,and 90°).The polarization orientation angle of the light scattered by the haze particles is introduced in the algorithm.No additional image-processing algorithm is needed in the postprocessing.It is found that the dehazed image suffers from little noise and the details of the objects close to the observer can be preserved well.In addition,this algorithm is also proved to be useful for preserving image colors.Experimental results demonstrate that such an algorithm has some universality in handling all kinds of haze.We think that this robust algorithm might be very suitable for real-time dehazing.Jian Liang Liyong Ren Enshi Qu Bingliang Hu Yingli Wang 2014Photonics Research2014,2,1:15
10Quercetin alleviates high glucose-induced Schwann cell damage by autophagy显示文摘Quercetin can reverse high glucose-induced inhibition of neural cell proliferation, and therefore may have a neuroprotective effect in diabetic peripheral neuropathy. It is difficult to obtain primary Schwann cells and RSC96 cells could replace primary Schwann cells in studies of the role of autophagy in the mechanism underlying diabetic peripheral neuropathy. Here, we show that under high glucose conditions, there are fewer autophagosomes in immortalized rat RSC96 cells and primary rat Schwann cells than under control conditions, the proliferative activity of both cell types is significantly impaired, and the expression of Beclin-1 and LC3, the molecular markers for autophagy, is significantly lower. After intervention with quercetin, the autophagic and proliferative activity of both cell types is rescued. These results suggest that quercetin can alleviate high glucose-induced damage to Schwann cells by autophagy.Ling Qu Xiaochun Liang Bei Gu Wei Liu 2014Neural Regeneration Research2014,9,12:14
11Multiple hypointense vessels on susceptibility-weighted imaging predict early neurological deterioration in acute ischaemic stroke patients with severe intracranial large artery stenosis or occlusion receiving intravenous thrombolysis显示文摘background and purpose Early neurological deterioration(END)is a common feature in patients with acute ischaemic stroke(AIS)receiving thrombolysis.This study aimed to investigate whether the presence of multiple hypointense vessels(MHVs)on susceptibility-weighted imaging(SWI)could predict END in patients with the anterior circulation AIS treated with recombinant tissue plasminogen activator(r-tPA).Methods This was a retrospective study focusing on AIS patients suffering from symptomatic stenosis or occlusion of the middle cerebral artery or internal carotid artery with r-tPA treatment.We collected clinical variables and initial haematological and neuroimaging findings.MHVs were measured on SWI performed after intravenous thrombosis and were defined as the presence of a greater number of veins or veins of a larger diameter with greater signal loss on SWI than those of the contralesional haemisphere.The degree of hyperintensity of MHVs was classified into four grades:none,subtle,moderate and extensive.END was defined as an increase in the National Institutes of Health Stroke Scale score by 2 points during the first 48 hours after the onset of symptoms.Multivariate logistic regressions were conducted to investigate the predictors of END.results The study included 61 patients(51 males and 10 females)with a mean age of 62.4±12.6 years.Thirty-five(57.4%)patients presented with MHVs:8(13.1%)were graded as subtle MHVs,while 23(37.7%)and 4(6.6%)were graded as moderate or extensive MHVs,respectively.Twenty patients(32.8%)presented with END.Logistic regression analysis showed that compared with patients without MHVs,moderate MHVs(adjusted OR 5.446,95%CI 1.360 to 21.800;p=0.017)and extensive MHVs(adjusted OR 15.240,95%CI 1.200 to 193.544;p=0.036)were significantly associated with END.Conclusions MHVs might be a useful predictor of END in AIS patients with symptomatic large artery stenosis or occlusion after r-tPA treatment.Yong-Lin Liu Han-Peng Yin Dong-Hai Qiu Jian-Feng Qu Huo-Hua Zhong Zhi-Hao Lu Fang Wang Man-Qiu Liang Yang-Kun Chen 2020Stroke & Vascular Neurology2020,5,4:14
12Chemical screen identifies a geroprotective role of quercetin in premature aging显示文摘Aging increases the risk of various diseases. The main goal of aging research is to find therapies that attenuate aging and alleviate aging-related diseases. In this study, we screened a natural product library for geroprotective compounds using Werner syndrome (WS) human mesenchymal stem cells (hMSCs), a premature aging model that we recently established. Ten candidate compounds were identified and quercetin was investigated in detail due to its leading effects. Mechanistic studies revealed that quercetin alleviated senescence via the enhancement of cell proliferation and restoration of heterochromatin architecture in WS hMSCs. RNA-sequencing analysis revealed the transcriptional commonalities and differences in the geroprotective effects by quercetin and Vitamin C. Besides WS hMSCs, quercetin also attenuated cellular senescence in Hutchinson-Gilford progeria syndrome (HGPS) and physiological-aging hMSCs. Taken together, our study identifies quercetin as a geroprotective agent against accelerated and natural aging in hMSCs, providing a potential therapeutic intervention for treating age-associated disorders.Lingling Geng Zunpeng Liu Weiqi Zhang Wei Li Zeming Wu Wei Wang Ruotong Ren Yao Su Peichang Wang Liang Sun Zhenyu Ju Piu Chan Moshi Song Jing Qu Guang-Hui Liu 2019Protein & Cell2019,10,6:13
13In vivo theranostics with near-infraredemitting carbon dots—highly efficient photothermal therapy based on passive targeting after intravenous administration显示文摘Carbon dots that exhibit near-infrared fluorescence(NIR CDs)are considered emerging nanomaterials for advanced biomedical applications with low toxicity and superior photostability and targeting compared to currently used photoluminescence agents.Despite progress in the synthesis of NIR CDs,there remains a key obstacle to using them as an in vivo theranostic agent.This work demonstrates that the newly developed sulfur and nitrogen codoped NIR CDs are highly efficient in photothermal therapy(PTT)in mouse models(conversion efficiency of 59%)and can be readily visualized by photoluminescence and photoacoustic imaging.The real theranostic potential of NIR CDs is enhanced by their unique biodistribution and targeting.Contrary to all other nanomaterials that have been tested in biomedicine,they are excreted through the body’s renal filtration system.Moreover,after intravenous injection,NIR CDs are accumulated in tumor tissue via passive targeting,without any active species such as antibodies.Due to their accumulation in tumor tissue without the need for intratumor injection,high photothermal conversion,excellent optical and photoacoustic imaging performance,and renal excretion,the developed CDs are suitable for transfer to clinical biomedical practice.Xin Bao Ye Yuan Jingqin Chen Bohan Zhang Di Li Ding Zhou Pengtao Jing Guiying Xu Yingli Wang Kateřina Holá Dezhen Shen Changfeng Wu Liang Song Chengbo Liu Radek Zbořil Songnan Qu 2018Light(Science & Applications)2018,7,1:13
14Antimony oxidation and adsorption by in-situ formed biogenic Mn oxide and Fe–Mn oxides显示文摘Antimony(Sb), which can be toxic at relatively low concentrations, may co-exist with Mn(Ⅱ)and/or Fe(Ⅱ) in some groundwater and surface water bodies. Here we investigated the potential oxidation and adsorption pathways of Sb(Ⅲ and V) species in the presence of Mn(Ⅱ) and Mn-oxidizing bacteria, with or without Fe(Ⅱ). Batch experiments were conducted to determine the oxidation and adsorption characteristics of Sb species in the presence of biogenic Mn oxides(BMOs), which were formed in-situ via the oxidation of Mn(Ⅱ) by a Mn-oxidizing bacterium(Pseudomonas sp. QJX-1). Results indicated that Sb(Ⅲ) ions could be oxidized to Sb(V) ions by BMO, but only Sb(V) originating from Sb(Ⅲ) oxidation was adsorbed effectively by BMO. Introduced Fe(Ⅱ) was chemically oxidized to Fe OOH, the precipitates of which mixed with BMO to form a new compound, biogenic Fe–Mn oxides(BFMO). The BMO part of the BFMO mainly oxidized and the Fe OOH of the BFMO mainly adsorbed the Sb species. In aquatic solutions containing both As(Ⅲ) and Sb(Ⅲ), the BFMO that formed in-situ preferentially oxidized Sb over As but adsorbed As more efficiently. Chemical analysis and reverse transcription real-time polymerase chain reaction revealed that the presence of Fe(Ⅱ), As(Ⅲ) and Sb(Ⅲ) accelerated the oxidation of Mn(Ⅱ) but inhibited the activity of Mn-oxidizing bacteria. These results provide significant insights into the biogeochemical pathways of Sb, Mn(Ⅱ) in aquatic ecosystems, with or without Fe(Ⅱ).Yaohui Bai William A.Jefferson Jinsong Liang Tingting Yang Jiuhui Qu 2017Journal of Environmental Sciences2017,29,4:12
15Insight-HXMT observations of the first binary neutron star merger GW170817显示文摘Finding the electromagnetic(EM) counterpart of binary compact star merger, especially the binary neutron star(BNS) merger,is critically important for gravitational wave(GW) astronomy, cosmology and fundamental physics. On Aug. 17, 2017,Advanced LIGO and Fermi/GBM independently triggered the first BNS merger, GW170817, and its high energy EM counterpart,GRB 170817 A, respectively, resulting in a global observation campaign covering gamma-ray, X-ray, UV, optical, IR, radio as well as neutrinos. The High Energy X-ray telescope(HE) onboard Insight-HXMT(Hard X-ray Modulation Telescope) is the unique high-energy gamma-ray telescope that monitored the entire GW localization area and especially the optical counterpart(SSS17 a/AT2017 gfo) with very large collection area(~1000 cm^2) and microsecond time resolution in 0.2-5 MeV. In addition,Insight-HXMT quickly implemented a Target of Opportunity(ToO) observation to scan the GW localization area for potential X-ray emission from the GW source. Although Insight-HXMT did not detect any significant high energy(0.2-5 MeV) radiation from GW170817, its observation helped to confirm the unexpected weak and soft nature of GRB 170817 A. Meanwhile,Insight-HXMT/HE provides one of the most stringent constraints(~10^(-7) to 10^(-6) erg/cm^2/s) for both GRB170817 A and any other possible precursor or extended emissions in 0.2-5 MeV, which help us to better understand the properties of EM radiation from this BNS merger. Therefore the observation of Insight-HXMT constitutes an important chapter in the full context of multi-wavelength and multi-messenger observation of this historical GW event.TiPei Li ShaoLin Xiong ShuangNan Zhang FangJun Lu LiMing Song XueLei Cao Zhi Chang Gang Chen Li Chen TianXiang Chen Yong Chen YiBao Chen YuPeng Chen Wei Cui WeiWei Cui JingKang Deng YongWei Dong YuanYuan Du MinXue Fu GuanHua Gao He Gao Min Gao MingYu Ge YuDong Gu Ju Guan ChengCheng Guo DaWei Han Wei Hu Yue Huang Jia Huo ShuMei Jia LuHua Jiang WeiChun Jiang Jing Jin YongJie Jin Bing Li ChengKui Li Gang Li MaoShun Li Wei Li Xian Li XiaoBo Li XuFang Li YanGuo Li ZiJian Li ZhengWei Li XiaoHua Liang JinYuan Liao CongZhan Liu GuoQing Liu HongWei Liu ShaoZhen Liu XiaoJing Liu Yuan Liu YiNong Liu Bo Lu XueFeng Lu Tao Luo Xiang Ma Bin Meng Yi Nang JianYin Nie Ge OU JinLu Qu Na Sai Liang Sun Yin Tan Lian Tao WenHui Tao YouLi Tuo GuoFeng Wang HuanYu Wang Juan Wang WenShuai Wang YuSa Wang XiangYang Wen BoBing WU Mei Wu GuangCheng Xiao He Xu YuPeng Xu LinLi Yan JiaWei Yang Sheng Yang YanJi Yang AiMei Zhang ChunLei Zhang ChengMo Zhang Fan Zhang HongMei Zhang Juan Zhang Qiang Zhang Shu Zhang Tong Zhang Wei Zhang WanChang Zhang WenZhao Zhang Yi Zhang Yue Zhang YiFei Zhang YongJie Zhang Zhao Zhang ZiLiang Zhang HaiSheng Zhao JianLing Zhao XiaoFan Zhao ShiJie Zheng Yue Zhu YuXuan Zhu ChangLin Zou 2018Science China(Physics,Mechanics & Astronomy)2018,61,3:12
16Low-dose quercetin positively regulates mouse healthspan显示文摘Dear Editor,Aging is the leading risk factor for many chronic diseases,accounting for almost 60%of all deaths worldwide.How to achieve healthy aging,alleviate aging-related diseases,and extend healthspan has become a main topic of biomedical research(He et al.,2019).Geroprotective compounds,such as metformin and rapamycin,have been shown to improve both healthspan and lifespan in mice(Martin-Montalvo et al.,2013;Bitto et al.,2016),whereas nicotinamide partially improves healthspan in mice(Mitchell et al.,2018).Lingling Geng Zunpeng Liu Si Wang Shuhui Sun Shuai Ma Xiaoqian Liu Piu Chan Liang Sun Moshi Song Weiqi Zhang Guang-Hui Liu Jing Qu 2019Protein & Cell2019,10,10:12

20Combination of Quercetin, Cinnamaldehyde and Hirudin Protects Rat Dorsal Root Ganglion Neurons against High Glucose-Induced Injury through Nrf-2/HO-1 Activation and NF-κB Inhibition显示文摘Objective: To examine the effects of the combination of quercetin(Q), cinnamaldehyde(C) and hirudin(H), a Chinese medicine formula on high glucose(HG)-induced apoptosis of cultured dorsal root ganglion(DRG) neurons. Methods: DRG neurons exposed to HG(45 mmol/L) for 24 h were employed as an in vitro model of diabetic neuropathy. Cell viability, reactive oxygen species(ROS) level and apoptosis were determined. The expression of nuclear factor of Kappa B(NF-κB), inhibitory kappa Bα(IκBα), phosphorylated IκBα and Nf-E2 related factor 2(Nrf2) were examined using reverse transcription-polymerase chain reaction(RT-PCR) and Western blot assay. The expression of hemeoxygenase-1(HO-1), interleukin-6(IL-6), tumor necrosis factor(TNF-α) and caspase-3 were also examined by RT-PCR and Western blot assay. Results: HG treatment markedly increased DRG neuron apoptosis via increasing intracellular ROS level and activating the NF-κB signaling pathway(P<0.05). Co-treatment with Q, C, H and their combination decreased HG-induced caspase-3 activation and apoptosis(P<0.05 or P<0.01). The expressions of NF-κB, IL-6 and TNF-α were downregulated, and Nrf2/HO-1 expression was up-regulated(P<0.05 or P<0.01). QCH has better effect in scavenging ROS, activating Nrf-2/HO-1, and down-regulating the NF-κB pathway than other treatment group. Conclusions: DRG neurons' apoptosis was increased in diabetic conditions, which was reduced by QCH formula treatment. The possible reason could be activating Nrf-2/HO-1 pathway, scavenging ROS, and inhibition of NF-κB activation. The effect of QCH combination was better than each monomer or the combination of the two monomers.SHI Yue LIANG Xiao-chun ZHANG Hong SUN Qing WU Qun-li QU Ling 2017Chinese Journal of Integrative Medicine2017,23,9:11
