| 1 | Resistance of Helicobacter pylori to antibiotics from 2000 to 2009 in Shanghai显示文摘AIM: To investigate the resistance of Helicobacter pylori (H. pylori ) to 6 commonly used antibiotics from 2000 to 2009 in Shanghai. METHODS: A total of 293 H. pylori strains were collected from 2000 to 2009 in Shanghai and tested for their susceptibility to metronidazole, clarithromycin, amoxicillin, furazolidone, levofloxacin and tetracycline using agar dilution. RESULTS: The resistant rates of H. pylori to clarithromycin (8.6%, 9.0% and 20.7%) and levofloxacin (10.3%, 24.0% and 32.5%) increased from 2000 to 2009 in Shanghai. The resistant rate of H. pylori to metronidazole remained stable (40%-50%). Only one strain of H. pylori isolated in 2005 was resistant to tetracycline. All strains were sensitive to amoxicillin and furazolidone.The resistant rate of H. pylori to antibiotics was not related with the sex, age and clinical outcome of patients. CONCLUSION: Resistance of H. pylori to antibiotics plays an important role in making treatment strategies against H. pylori -associated diseases. | Qin-Juan Sun Xiao Liang Qing Zheng Wei-Qi Gu WenZhong Liu Shu-Dong Xiao Hong Lu | 2010 | World Journal of Gastroenterology2010，16，40： | 90 |

| 4 | Liver cancer stem cell markers: Progression and therapeutic implications显示文摘Cancer stem cells(CSCs) are a small subpopulation in cancer, have been proposed to be cancer-initiating cells, and have been shown to be responsible for chemotherapy resistance and cancer recurrence. The identification of CSC subpopulations inside a tumor presents a new understanding of cancer development because it implies that tumors can only be eradicated by targeting CSCs. Although advances in liver cancer detection and treatment have increased the possibility of curing the disease at early stages, unfortunately, most patients will relapse and succumb to their disease. Strategies aimed at efficiently targeting liver CSCs are becoming important for monitoring the progress of liver cancer therapy and for evaluating new therapeutic approaches. Herein, we provide a critical discussion of biological markers described in the literature regarding liver cancer stem cells and the potential of these markers to serve as therapeutic targets. | Jing-Hui Sun Qing Luo Ling-Ling Liu Guan-Bin Song | 2016 | World Journal of Gastroenterology2016，22，13： | 31 |
| 5 | Ablation of gut microbiota alleviates obesity-induced hepatic steatosis and glucose intolerance by modulating bile acid metabolism in hamsters显示文摘Since metabolic process differs between humans and mice, studies were performed in hamsters, which are generally considered to be a more appropriate animal model for studies of obesityrelated metabolic disorders. The modulation of gut microbiota, bile acids and the farnesoid X receptor(FXR) axis is correlated with obesity-induced insulin resistance and hepatic steatosis in mice. However,the interactions among the gut microbiota, bile acids and FXR in metabolic disorders remained largely unexplored in hamsters. In the current study, hamsters fed a 60% high-fat diet(HFD) were administeredvehicle or an antibiotic cocktail by gavage twice a week for four weeks. Antibiotic treatment alleviated HFD-induced glucose intolerance, hepatic steatosis and inflammation accompanied with decreased hepatic lipogenesis and elevated thermogenesis in subcutaneous white adipose tissue(sWAT). In the livers of antibiotic-treated hamsters, cytochrome P450 family 7 subfamily B member 1(CYP7 B1) in the alternative bile acid synthesis pathway was upregulated, contributing to a more hydrophilic bile acid profile with increased tauro-β-muricholic acid(TβMCA). The intestinal FXR signaling was suppressed but remained unchanged in the liver. This study is of potential translational significance in determining the role of gut microbiota-mediated bile acid metabolism in modulating diet-induced glucose intolerance and hepatic steatosis in the hamster. | Lulu Sun Yuanyuan Pang Xuemei Wang Qing Wu Huiying Liu Bo Liu George Liu Min Ye Wei Kong Changtao Jiang | 2019 | Acta Pharmaceutica Sinica B2019，9，4： | 29 |
| 6 | The prognostic value of preoperative serum levels of CEA,CA19-9 and CA72-4 in patients with colorectal cancer显示文摘INTRODUCTIONCarcinoembryonic antigen ( CEA) , originally described by Gold and Freedman [1] in 1965, is now an acknowledged member of immunoglobulin superfamily[2],with a role as an intracellular adhesion molecule[3].Carbohydrate antigen 19-9(CA19-9), obtained with a monoclonal antibody produced by immunizing a monoclonal antibody produced by immunizing a mouse with a colonic cancer cell line in 1979[4],is a ligand for E-selectin that plays an important role in the addhesion of cancer cells to endothelial cells [5,6]. | Chao Xu Zheng~1 Wen Hua Zhan~1 Ji Zong Zhao~2 Dong Zheng~3 Dong Ping Wang~1 Yu Long He~1 Zhang Qing Zheng~1 ~1Department of General Surgery,~2Laboratory of Surgery,~3Department of Medicine,First Affiliated Hospital,Sun Yat-Sen University of Medical Sciences,Guangzhou 510080,Guangdong Province,ChinaDr.Chao Xu Zheng now working as a surgeon and lecturer in the Department of General Surgery,First Affiliated Hospital,Sun Yat-Sen University of Medical Sciences,who is a Ph.D.student,having 7 papers published. | 2001 | World Journal of Gastroenterology2001，7，3： | 25 |
| 7 | Advanced landfill leachate treatment using a two-stage UASB-SBR system at low temperature显示文摘A two-stage upflow anaerobic sludge blanket(UASB) and sequencing batch reactor(SBR) system was introduced to treat landfill leachate for advanced removal of COD and nitrogen at low temperature.In order to improve the total nitrogen(TN) removal efficiency and to reduce the COD requirement for denitrification,the raw leachate with recycled SBR nitrification supernatant was pumped into the first-stage UASB(UASB1) to achieve simultaneous denitrification and methanogenesis.The results showed that UASB1 played an important role in COD removal and UASB2 and SBR further enhanced the nutrient removal efficiency.When the organic loading rates of UASB1,UASB2 and SBR were 11.95,1.63 and 1.29 kg COD/(m3·day),respectively,the total COD removal efficiency of the whole system reached 96.7%.The SBR acted as the real undertaker for NH4+-N removal due to aerobic nitrification.The system obtained about 99.7% of NH4+-N removal efficiency at relatively low temperature(14.9-10.9°C).More than 98.3% TN was removed through complete denitrification in UASB1 and SBR.In addition,temperature had a significant effiect on the rates of nitrification and denitrification rather than the removal of TN and NH4+-N once the complete nitrification and denitrification were achieved. | Hongwei Sun,Qing Yang,Yongzhen Peng,Xiaoning Shi,Shuying Wang,Shujun Zhang Key Laboratory of Beijing Water Quality Science and Water Envirocnnment Recovery Engineering,Beijing University of Technology,Beijing 100124,China | 2010 | Journal of Environmental Sciences2010，22，4： | 26 |
| 8 | Eco-toxicity of petroleum hydrocarbon contaminated soil显示文摘Total petroleum hydrocarbons (TPH) contaminated soil samples were collected from Shengli Oilfield of China. Toxicity analysis was carried out based on earthworm acute toxicity, plant growth experiment and luminescent bacteria test. The soil was contaminated by-petroleum hydrogcarbons with TPH concentration of 10.57%. With lethal and sub-lethal rate as endpoint, earthworm test showed that the LD 50 (lethal dose 50%) values in 4 and 7 days were 1.45% and 1.37% respectively, and the inhibition rate of earthworm body weight increased with higher oil concentration. TPH pollution in the soil inhibited seed germination in both wheat and maize experiment when the concentration of petroleum was higher than 0.1%. The EC 50 (effective concentration 50%) for germination is 3.04% and 2.86% in maize and wheat, respectively. While lower value of EC 50 for root elongation was to be 1.11% and 1.64% in maize and wheat, respectively, suggesting higher sensitivity of root elongation on petroleum contamination in the soil. The EC 50 value in luminescent bacteria test was 0.47% for petroleum in the contaminated soil. From the experiment result, it was concluded that TPH content of 1.5% is considered to be a critical value for plant growth and living of earthworm and 0.5% will affect the activity of luminescent bacteria. | Jingchun Tang Min Wang Fei Wang Qing Sun Qixing Zhou | 2011 | Journal of Environmental Sciences2011，23，5： | 26 |
| 9 | Human umbilical cord mesenchymal stem cells promote peripheral nerve repair via paracrine mechanisms显示文摘Human umbilical cord-derived mesenchymal stem cells(h UCMSCs) represent a promising young-state stem cell source for cell-based therapy. h UCMSC transplantation into the transected sciatic nerve promotes axonal regeneration and functional recovery. To further clarify the paracrine effects of h UCMSCs on nerve regeneration, we performed human cytokine antibody array analysis, which revealed that h UCMSCs express 14 important neurotrophic factors. Enzyme-linked immunosorbent assay and immunohistochemistry showed that brain-derived neurotrophic factor, glial-derived neurotrophic factor, hepatocyte growth factor, neurotrophin-3, basic fibroblast growth factor, type I collagen, fibronectin and laminin were highly expressed. Treatment with h UCMSC-conditioned medium enhanced Schwann cell viability and proliferation, increased nerve growth factor and brain-derived neurotrophic factor expression in Schwann cells, and enhanced neurite growth from dorsal root ganglion explants. These findings suggest that paracrine action may be a key mechanism underlying the effects of h UCMSCs in peripheral nerve repair. | Zhi-yuan Guo Xun Sun Xiao-long Xu Qing Zhao Jiang Peng Yu Wang | 2015 | Neural Regeneration Research2015，10，4： | 26 |
| 10 | Arctic Sea Ice and Eurasian Climate:A Review显示文摘The Arctic plays a fundamental role in the climate system and has shown significant climate change in recent decades,including the Arctic warming and decline of Arctic sea-ice extent and thickness. In contrast to the Arctic warming and reduction of Arctic sea ice, Europe, East Asia and North America have experienced anomalously cold conditions, with record snowfall during recent years. In this paper, we review current understanding of the sea-ice impacts on the Eurasian climate.Paleo, observational and modelling studies are covered to summarize several major themes, including: the variability of Arctic sea ice and its controls; the likely causes and apparent impacts of the Arctic sea-ice decline during the satellite era,as well as past and projected future impacts and trends; the links and feedback mechanisms between the Arctic sea ice and the Arctic Oscillation/North Atlantic Oscillation, the recent Eurasian cooling, winter atmospheric circulation, summer precipitation in East Asia, spring snowfall over Eurasia, East Asian winter monsoon, and midlatitude extreme weather; and the remote climate response(e.g., atmospheric circulation, air temperature) to changes in Arctic sea ice. We conclude with a brief summary and suggestions for future research. | GAO Yongqi SUN Jianqi LI Fei HE Shengping Stein SANDVEN YAN Qing ZHANG Zhongshi Katja LOHMANN Noel KEENLYSIDE Tore FUREVIK SUO Lingling | 2015 | Advances in Atmospheric Sciences2015，32，1： | 21 |
| 11 | BMAL1 knockout macaque monkeys display reduced sleep and psychiatric disorders显示文摘Circadian disruption is a risk factor for metabolic, psychiatric and age-related disorders, and non-human primate models could help to develop therapeutic treatments. Here, we report the generation of BMAL1 knockout cynomolgus monkeys for circadian-related disorders by CRISPR/Cas9 editing of monkey embryos. These monkeys showed higher nocturnal locomotion and reduced sleep, which was further exacerbated by a constant light regimen. Physiological circadian disruption was reflected by the markedly dampened and arrhythmic blood hormonal levels. Furthermore, BMAL1-deficient monkeys exhibited anxiety and depression, consistent with their stably elevated blood cortisol, and defective sensory processing in auditory oddball tests found in schizophrenia patients. Ablation of BMAL1 up-regulated transcriptional programs toward inflammatory and stress responses, with transcription networks associated with human sleep deprivation, major depressive disorders, and aging. Thus, BMAL1 knockout monkeys are potentially useful for studying the physiological consequences of circadian disturbance, and for developing therapies for circadian and psychiatric disorders. | Peiyuan Qiu Jian Jiang Zhen Liu Yijun Cai Tao Huang Yan Wang Qiming Liu Yanhong Nie Fang Liu Jiumu Cheng Qing Li Yun-Chi Tang Mu-ming Poo Qiang Sun Hung-Chun Chang | 2019 | National Science Review2019，6，1： | 21 |

| 13 | Surface Active Sites on Co_(3)O_(4) Nanobelt and Nanocube Model Catalysts for CO Oxidation显示文摘CO oxidation has been performed on Co_(3)O_(4) nanobelts and nanocubes as model catalysts.The Co_(3)O_(4) nanobelts which have a predominance of exposed{011}planes are more active than Co_(3)O_(4) nanocubes with exposed{001}planes.Temperature programmed reduction of CO shows that Co_(3)O_(4) nanobelts have stronger reducing properties than Co_(3)O_(4) nanocubes.The essence of shape and crystal plane effect is revealed by the fact that turnover frequency of Co3+sites of{011}planes on Co_(3)O_(4) nanobelts is far higher than that of{001}planes on Co_(3)O_(4) nanocubes. | Linhua Hu Keqiang Sun Qing Peng Boqing Xu Yadong Li | 2010 | Nano Research2010，3，5： | 21 |
| 14 | Impaired balance of T helper 17/T regulatory cells in carbon tetrachloride-induced liver fibrosis in mice显示文摘AIM:To investigate the effect of T helper(Th)17/T regulatory(Treg)cells on hepatic fibrosis in mice and its possible mechanism.METHODS:Hepatic fibrosis was induced by intraperitoneal injection of carbon tetrachloride.Hepatic pathological changes were observed by hematoxylin and eosin staining;the protein levels of interleukin(IL)-6,transforming growth factor(TGF)-βandα-smooth muscle actin(SMA)in liver tissue were determined by Western blotting;and the frequency of Th17 and Treg cells in the liver was estimated by flow cytometry.In addition,hepatic stellate cells were isolated from healthy mouse liver and co-cultured with Th17 or Treg cells.Immunofluorescence staining and Western blotting were performed to determine the change in HSC activation.RESULTS:In the model group,there were different degrees of fibroplasia,degeneration and necrosis.The protein levels of IL-6,TGF-βandα-SMA in liver tissue were significantly higher than those in the control group at 12 wk(P<0.05).Compared with the control group,the frequency of Th17 cells in the model group was increased but the frequency of Treg cells decreased gradually.Furthermore,at 4,8 and 12 wk,there were significant differences in the number of Th17 cells(0.52%±0.16%,1.46%±0.24%,and2.60%±0.41%,respectively,P<0.05)and Treg cells(2.99%±0.40%,2.16%±0.50%,and 1.49%±0.34%,respectively,P<0.05).In vitro,Th17 cells promoted,whereas Treg cells inhibited the expression ofα-SMA,both in a dose-dependent manner,compared with the control group.CONCLUSION:Th17/Treg imbalance exists in mice with liver fibrosis,which potentially promotes liver fibrosis via HSC activation. | Xiao-Fei Sun Lei Gu Wen-Sheng Deng Qing Xu | 2014 | World Journal of Gastroenterology2014，20，8： | 20 |
| 15 | Outcomes and possible risk factors associated with axis alignment and rotational stability after implantation of the Toric implantable collamer lens for high myopic astigmatism显示文摘·AIM:To assess the visual outcomes and possible risk factors associated with axis alignment and rotational stability after implantation of Toric implantable collamer lens (TICL) for the correction of high myopic astigmatism. ·METHODS:In this prospective, nonrandomized clinical study, 54 consecutive eyes of 29 patients with high myopic astigmatism received TICL implantation. To evaluate postoperative axis deviation from the intended axis, a digital anterior segment photograph was taken. The ultrasound biomicroscopy(UBM) was used to observe footplate-position. ·RESULTS:After mean follow-up of 8.6 months, mean manifest refractive cylinder (MRC) decreased 79.3% from (-1.88±1.49)D preoperatively to (0.39±0.61)D postoperatively. MRC within 1.00D occurred in 68.5% (37/54) of eyes, whereas 48.1% (26/54) had MRC within 0.50D. Mean manifest refraction spherical equivalent (MRSE) changed from (-12.08±4.22)D preoperatively to (-0.41±0.61)D postoperatively. Uncorrected binocular vision of 20/20 or better occurred in 72.2%(39/54) of patients compared with binocular best-corrected visual acuity (BCVA) of 20/20 or better in 44.4% (24/54) preoperatively. The mean difference between intended and achieved TICL axes was (6.96±8.37)°. Footplates of TICLs were in the ciliary sulcus in 22 eyes (46.3%), below the ciliary sulcus in 32 eyes (53.7%). The angle of TICL rotation had significant correlation with the footplates-position (t =2.127; P =0.045) and the postoperative TICL vaulting (r =-0.516; P =0.000). ·CONCLUSION:The results of our study further support the safety, efficacy and predictability of TICL for the correct high myopic astigmatism. The footplate-position of TICL and vault value should be taken into consideration as two possible risks factors for TICL rotation. | Xun-Lun Sheng, De-Jun Zhu | 2012 | International Journal of Ophthalmology(English edition)2012，5，4： | 19 |

| 20 | Comprehensive metabolomics expands precision medicine for triple-negative breast cancer显示文摘Metabolic reprogramming is a hallmark of cancer.However,systematic characterizations of metabolites in triple-negative breast cancer(TNBC)are still lacking.Our study profiled the polar metabolome and lipidome in 330 TNBC samples and 149 paired normal breast tissues to construct a large metabolomic atlas of TNBC.Combining with previously established transcriptomic and genomic data of the same cohort,we conducted a comprehensive analysis linking TNBC metabolome to genomics.Our study classified TNBCs into three distinct metabolomic subgroups:C1,characterized by the enrichment of ceramides and fatty acids;C2,featured with the upregulation of metabolites related to oxidation reaction and glycosyl transfer;and C3,having the lowest level of metabolic dysregulation.Based on this newly developed metabolomic dataset,we refined previous TNBC transcriptomic subtypes and identified some crucial subtype-specific metabolites as potential therapeutic targets.The transcriptomic luminal androgen receptor(LAR)subtype overlapped with metabolomic C1 subtype.Experiments on patient-derived organoid and xenograft models indicate that targeting sphingosine-1-phosphate(S1P),an intermediate of the ceramide pathway,is a promising therapy for LAR tumors.Moreover,the transcriptomic basal-like immune-suppressed(BLIS)subtype contained two prognostic metabolomic subgroups(C2 and C3),which could be distinguished through machine-learning methods.We show that N-acetyl-aspartyl-glutamate is a crucial tumor-promoting metabolite and potential therapeutic target for high-risk BLIS tumors.Together,our study reveals the clinical significance of TNBC metabolomics,which can not only optimize the transcriptomic subtyping system,but also suggest novel therapeutic targets.This metabolomic dataset can serve as a useful public resource to promote precision treatment of TNBC. | Yi Xiao Ding Ma Yun-Song Yang Fan Yang Jia-Han Ding Yue Gong Lin Jiang Li-Ping Ge Song-Yang Wu Qiang Yu Qing Zhang François Bertucci Qiuzhuang Sun Xin Hu Da-Qiang Li Zhi-Ming Shao Yi-Zhou Jiang | 2022 | Cell Research2022，32，5： | 18 |
