| 2 | Influence of dexamethasone on mesenteric lymph node of rats with severe acute pancreatitis显示文摘AIM: To study the influence and mechanisms of dexamethasone on mesenteric lymph node of rats with severe acute pancreatitis (SAP). METHODS: The SAP rats were assigned to model, treated or sham-operated groups. The mortality, pathological changes of mesenteric lymph nodes, expression levels of NF-kB, P-selectin, Bax, Bcl-2 and caspase-3 protein and changes in apoptotic indexes in lymph nodes were observed at 3, 6 and 12 h after operation. The blood levels of endotoxin, superoxide dismutase (SOD), malondialdehyde (MDA), and endothelin-1 (ET-1) in blood were determined. RESULTS: SOD content, expression of Bax protein and apoptotic index were significantly higher in the treated group than in the model group at different time points (P < 0.05 or P < 0.01). Other blood-detecting indexes and histopathological scores of mesenteric lymphnodes were lower in the treated than in the model group (P < 0.05, P < 0.01 or P < 0.01). NF-kB protein expression was negative in all groups. Comparing P-selectin and caspase-3 expression levels among all three groups, there was no marked difference between the model and treated group. CONCLUSION: Dexamethasone can protect mesen-teric lymph nodes. The mechanism may be by reducing the content of inflammatory mediators in the blood and inducing lymphocyte apoptosis. | Xi-Ping Zhang Hong-Miao Xu Yi-Yu Jiang Shuo Yu Yang Cai Bei Lu Qi Xie Tong-Fa Ju | 2008 | World Journal of Gastroenterology2008,14,22: | 14 |
| 3 | Autophagy-related proteins Beclin-1 and LC3 predict cetuximab efficacy in advanced colorectal cancer显示文摘AIM:To investigate the utility of Beclin-1 and LC3,two autophagy-related proteins,in predicting the cetuximab efficacy in advanced colorectal cancer(ACRC) . METHODS:The data of 85 patients with ACRC treated at the Sun Yat-sen University Cancer Center from March 1,2005 to December 31,2008 were studied,including 45 cases treated with cetuximab-containing chemotherapy and 40 cases treated with non-cetuximab-containing chemotherapy.Beclin-1 and LC3 expression was evaluated by immunohistochemistry,and KRAS status was evaluated by polymerase chain reaction. RESULTS:Beclin-1 and LC3 expression in ACRC wassignificantly correlated(r=0.44,P<0.01);however,LC3 was more highly expressed in cancerous tissues than in normal tissues(Z=-2.63,P<0.01) .In the cetuximab-containing chemotherapy group,patients with low LC3 expression had higher objective response rates(ORRs) than those with high LC3 expression(52.9%vs 17.9%,P=0.01) ,and patients with low Beclin-1 expression had a longer median progressionfree survival(PFS) than their counterparts with higher Beclin-1 expression(9.0 mo vs 3.0 mo,P=0.01) . However,neither of these predictive relationships was detected in the group treated with non-cetuximabcontaining chemotherapy.Patients with wild-type KRAS had higher ORRs(42.3%vs 9.1%,P=0.049) and disease control rates(DCRs)(73.1%vs 36.4%,P= 0.035) ,and longer median PFS(5.5 mo vs 2.5 mo,P= 0.02) than those with mutant KRAS in the cetuximabcontaining chemotherapy group.Neither Beclin-1(P= 0.52) nor LC3(P=0.32) expression was significantly correlated with KRAS status. CONCLUSION:Patients with low Beclin-1 expression had a longer PFS than those with high Beclin-1 expression,and patients with low LC3 expression had a higher ORR in ACRC patients treated with cetuximab-containing chemotherapy. | Gui-Fang Guo Wen-Qi Jiang Bei Zhang Yu-Chen Cai Rui-Hua Xu Xu-Xian Chen Fang Wang Liang-Ping Xia | 2011 | World Journal of Gastroenterology2011,17,43: | 14 |
| 4 | Factors predisposing to severe acute pancreatitis:evaluation and prevention显示文摘AIM: To analyze factors predisposing to the infections associated with severe acute pancreatitis (SAP) and to work out ways for its prevention.METHODS: Total 208 cases of SAP treated in this hospital from Jan. 1980 to Dec. 2001 were retrospectively analyzed.RESULTS: Statistical difference in the incidence of the aforementioned infections was found between the following pairs: between the groups of bloody or non-bloody ascites,paralytic ileus lasting shorter or longer than 5 days, Ranson scores lower or higher than 5, hematocrit lower or higher than 45 %, CT Balthazar scores lower or higher than 7 and between 1980.1-1992.6 or 1992.7-2001.12 admissions (χ2>3.84, P<0.05), while no statistical difference was established between the groups of biliogenic and nonbiliogenic pancreatitis, serum amylase <200 U/L and ≥200U/L, serum calcium <2 mmol/L and ≥ 2 mmol/L or groups of total parenteral nutrition shorter or longer than 7 days (χ2<3.84, P>0.05).CONCLUSION: Occurrence of infection in patients with SAP is closely related with bloody ascites, paralytic ileus ≥5 days, Ranson scores ≥5, hematocrit ≥45 % and CT Balthazar Scores ≥7, but not with pathogens, serum calcium and total parenteral nutrition (TPN). Comprehensive prevention of pancreatic infection and practice of individualized therapy contribute to reducing the incidence of infection. | Bei Sun Ha-Li Li Yue Gao Jun Xu Hong-Chi Jiang Department of General Surgery,First Clinical Hospital,Harbin Medical University,Harbin 150001,China | 2003 | World Journal of Gastroenterology2003,9,5: | 14 |
| 5 | Factors Associated with Thrombolysis Outcome in Ischemic Stroke Patients with Atrial Fibrillation显示文摘The outcome of early intravenous thrombolysis for ischemic stroke in patients with atrial fibrillation(AF)is worse than that without thrombosis. How to increase the efficacy of intravenous thrombolysis for AF-related ischemic stroke remains largely unknown. In this study, we investigated factors that influence the effect of intravenous thrombolysis in these patients. Our results showed that thrombolysis was independently associated with a favorable outcome(P \ 0.001) and did not influence the mortality of AF-related ischemic stroke, although it increased the risk of hemorrhage within 24 h after treatment. Risk factors for a poor outcome at admission were:heart failure(P = 0.045); high systolic pressure(P = 0.039); high blood glucose(P = 0.030); and a high National Institutes of Health Stroke Scale(NIHSS) score(P \ 0.001). Moreover, high systolic pressure at admission(P = 0.007), high blood glucose(P = 0.027), and a high NIHSS score(P \ 0.001) were independent risk factors for mortality at 3 months. Besides thrombolysis, a high NIHSS score(P = 0.006) and warfarin taken within 48 h before stroke onset(P = 0.032) were also independent risk factors for symptomatic hemorrhage within 24 h after treatment. Ischemic stroke patients with AF benefited from intravenous thrombolysis with recombinant tissue plasminogen activator within 4.5 h after stroke. | Qiuyun Zhao Xiaobo Li Wanli Dong Min Ye Yongjun Cao Meijuan Zhang Qiantao Cheng Junshan Zhou Guofang Chen Ming Yu Shanshan Hong Xiue Wei Bei Wang Guiyun Cui Peng Zhang Hong Ding Rongzhen Xu Yan Chen Yun Xu | 2016 | Neuroscience Bulletin2016,32,2: | 13 |
| 6 | Dynamic mechanical characteristics and application of constant resistance energy-absorbing supporting material显示文摘In deep underground engineering,rock burst and other dynamic disasters are prone to occur due to stress concentration and energy accumulation in surrounding rock.The control of dynamic disasters requires bolts and cables with high strength,high elongation,and high energy-absorbing capacity.Therefore,a constant resistance energy-absorbing(CREA)material is developed.In this study,the dynamic characteristics of the new material are obtained via the drop hammer tests and the Split Hopkinson Pressure Bar(SHPB)tests of the new material and two common bolt(CB)materials widely used in the field.The test results of drop hammer test and SHPB test show that the percentage elongation of CREA material is more than 2.64 and 3.22 times those of the CB material,and the total impact energy acting on CREA material is more than 18.50 and 21.84 times,respectively,indicating that the new material has high elongation and high energy-absorbing capacity.Subsequently,the CREA bolts and cables using the new material are developed,which are applied in roadways with high stress and strong dynamic disturbance.The field monitoring results show that CREA bolts and cables can effectively control the surrounding rock deformation and ensure engineering safety. | Qi Wang Shuo Xu Manchao He Bei Jiang Huayong Wei Yue Wang | 2022 | International Journal of Mining Science and Technology2022,32,3: | 9 |
| 7 | Neoproterozoic sedimentary facies and glacial periods in the southwest of Tarim Block显示文摘Based on the analysis of sedimentary facies and chemical index of alteration(CIA) in Nanhua and Ediacaran Systems in the southwest of Tarim Block,some features of glacial records in Neoproterozoic become more clear.Six sedimentary facies have been divided in the study area,including alluvial fan facies,lacustrine facies,glacial facies,littoral facies,neritic facies,and lagoonal facies,showing that this area underwent a process from continent to marine,with mainly littoral and neritic sedimentation.Two cold events have been recognized by analysis of CIA values in the study area,called Bolong and Yutang glaciation,respectively.They present as thick-layer tillite deposition in the Bolong Formation and thin-layer tillite deposition in the Yutang Formation,respectively.The Bolong glacial period in the study area can be correlated to the Yulmeinak glacial period in Aksu area,Tereeken glacial period in Qurugtagh area,and the Nantuo glacial period in South China,which is equivalent to the universally acknowledged Marinoan glacial period.The Yutang glacial period can be correlated to the Hankalchough glacial period in Qurugtagh,which is equivalent to Gaskers glaciation in Newfoundland. | TONG QinLong WEI Wei XU Bei | 2013 | Science China Earth Sciences2013,56,6: | 9 |
| 8 | Geometry,kinematics and evolution of the Tongbai orogenic belt显示文摘The Tongbai orogenic belt (TOB) is composed of six tectonic units. From south to north these units are: Tongbai gneiss rise (TGR); Hongyihe-Luozhuang eclogite belt (HLE); Ma- opo-Hujiazhai igneous rock belt (MHI); Zhoujiawan flysch belt (ZFB); Yangzhuang greenschist belt (YGB); and Dongjiazhuang marble belt (DMB).The geometry and kinematic images of the TOB in- clude: the antiformal structures caused by a later uplift process, the top-to-north ductile shear struc- ture that related to a process that the ultrahigh pressure rocks are brought to surface, the top-to-south ductile shear thrust and the sinistrial shear structures related to a south-north direction compression, and the east-west direction fold structures in the upper crust. In the view of the multistage subduc- tion-collision orogenic belt, according to the characters of petrology and its distribution, geometry, kinematics and structural chronology in these tectonic units, tectonic evolution of the TOB can be divided into four stages: oceanic crust subduction during 400―300 Ma, continental collision during 270―250 Ma, continental deep subduction and uplift during 250―205 Ma and doming deformation during 200―185 Ma. | HUANG Shaoying XU Bei WANG Changqiu ZHAN Sheng DENG Rongjing | 2006 | Science China Earth Sciences2006,49,8: | 9 |
| 9 | An investigation of cellular distribution of manganese in hyperaccumlator plant Phytolacca acinosa Roxb. using SRXRF analysis显示文摘Phytolacca acinosa Roxb. (P. acinosa) is a recently discovered mangane se hyperaccumulator plant from southern China. It is a good candidate for phytor emediation of manganese(Mn) polluted soil for its high biomass and fast growth. Knowledge of the tissue localization and identification of heavy metals can prov ide essential information on metal toxicity and bioaccumulation mechanisms. Sync hrotron radiation X-ray fluorescence spectroscopy (SRXRF) microprobe was used in this study to investigate the cellular distributions of Mn and other elements i n root, stem, leaf, petiole and midrib of P. acinosa. The highest Mn content was found in the vascular tissues of root, stem, petiole and midrib. Cortex in root played a key role in Mn absorption and Mn was limited in the vascular bundle du ring the process of transportation in stem. Moreover, Mn content in leaf epiderm is was higher than that in mesophyll, which suggested that the sequestration of Mn in leaf epidermis might be one of the detoxification mechanisms of P. acinosa . The significance of other elemental (such as P, S, K, Ca, Fe, Zn and Cu) distr ibution patterns and the correlation with Mn were also discussed. | XU Xiang-hua SHI Ji-yan CHEN Ying-xu XUE Sheng-guo WU Bei HUANG Yu-ying | 2006 | Journal of Environmental Sciences2006,18,4: | 9 |

| 11 | Type 1 CD8^+ T Cells are Superior to Type 2 CD8^+ T Cells in Tumor Immunotherapy due to Their Efficient Cytotoxicity,Prolonged Survival and Type 1 Immune Modulation显示文摘CD8+ cytotoxic T(Tc) cells play a crucial role in host immune responses to cancer,and in this context,adoptive CD8+ Tc cell therapy has been studied in numerous animal tumor models. Its antitumor efficacy is,to a large extent,determined by the ability of Tc cells to survive and infiltrate tumors. In clinical trials,such in vitro-activated T cells often die within hours to days,and this greatly limits their therapeutic efficacy. CD8+ Tc cells fall into two subpopulations based upon their differential cytokine secretion. In this study,we in vitro generated that ovalbumin(OVA) -pulsed dendritic cell(DCOVA) -activated CD8+ type 1 Tc(Tc1) cells secreting IFN-γ,and CD8+ type 2 Tc(Tc2) cells secreting IL-4,IL-5 and IL-10,which were derived from OVA-specific T cell receptor(TCR) transgenic OT I mice. We then systemically investigated the in vitro and in vivo effector function and survival of Tc1 and Tc2 cells,and then assessed their survival kinetics after adoptively transferred into C57BL/6 mice,respectively. We demonstrated that,when compared to CD8+ Tc2,Tc1 cells were significantly more effective in perforin-mediated cytotoxicity to tumor cells,had a significantly higher capacity for in vivo survival after the adoptive T cell transfer,and had a significantly stronger therapeutic effect on eradication of well-established tumors expressing OVA in animal models. In addition,CD8+ Tc1 and Tc2 cells skewed the phenotype of CD4+ T cells toward Th1 and Th2 type,respectively. Therefore,the information regarding the differential effector function,survival and immune modulation of CD8+ Tc1 and Tc2 cells may provide useful information when preparing in vitro DC-activated CD8+ T cells for adoptive T cell therapy of cancer. | Zhenmin Ye Chaoke Tang Shulin Xu Bei Zhang Xueshu Zhang Terence Moyana Jicheng Yang Jim Xiang | 2007 | Cellular & Molecular Immunology2007,4,4: | 8 |
| 12 | Hierarchically nanostructured porous TiO_2(B) with superior photocatalytic CO_2 reduction activity显示文摘Hierarchically nanostructured, porous TiO_2(B) microspheres were synthesized by a microwave-assisted solvothermal method combined with subsequent heat treatment in air. The materials were carefully characterized by scanning and transmission electron microscopy, X-ray diffraction, CO_2 adsorption, and a range of spectroscopies, including Raman, infrared, X-ray photoelectron and UV-Vis spectroscopy. The hierarchical TiO_2(B) particles are constructed by ultrathin nanosheets and possess large specific surface area, which provided many active sites for CO_2 adsorption as well as CO_2 conversion. The TiO_2(B)nanostructures exhibited marked photocatalytic activity for CO_2 reduction to methane and methanol. Anatase TiO_2 and P25 were used as the reference photocatalysts. Transient photocurrent measurement also proved the higher photoactivity of TiO_2(B) than that of anatase TiO_2. In-situ infrared spectrum was measured to identify the intermediates and deduce the conversion process of CO_2 under illumination over TiO_2(B) photocatalyst. | Tingmin Di Jinfeng Zhang Bei Cheng Jiaguo Yu Jingsan Xu | 2018 | Science China Chemistry2018,61,3: | 8 |

| 14 | A Facile Strategy for Non-fluorinated Intrinsic Low-k and Low-loss Dielectric Polymers: Valid Exploitation of Secondary Relaxation Behaviors显示文摘High-performance low-k and low-loss circuit materials are urgently needed in the field of microelectronics due to the upcoming FifthGeneration Mobile Communications Technology(5 G Technology).Herein,a facile design strategy for non-fluorinated intrinsic low-k and low-loss polyimides is reported by fully considering the secondary relaxation behaviors of the polymer chains.A new amorphous non-fluorinated polymer(TmBPPA)with a k value of 2.23 and a loss tangent lower than 3.94×10^-3 at 104 Hz has been designed and synthesized,which to the best of our knowledge is the lowest value amongst the non-fluorinated and non-porous polymers reported in literature.Meanwhile,TmBPPA exhibits excellent overall properties,such as excellent thermostability,good mechanical properties,low moisture absorption,and high bonding strength.As high-performance flexible circuit materials,all these characteristics are highly expected to meet the present and future demands for high density,high speed,and high frequency electronic circuit used in 5 G wireless networks. | Chao Qian Zhen-Guo Fan Wei-Wen Zheng Run-Xin Bei Tian-Wen Zhu Si-Wei Liu Zhen-Guo Chi Matthew P.Aldred Xu-Dong Chen Yi Zhang Jia-Rui Xu | 2020 | Chinese Journal of Polymer Science2020,38,3: | 7 |

| 17 | Tissue microarrays in pathological examination of apoptotic acinar cells induced by dexamethasone in the pancreas of rats with severe acute pancreatitis显示文摘BACKGROUND:The good therapeutic effects of large dose of dexamethasone on severe acute pancreatitis(SAP) patients have been proved.This study was designed to investigate the influence of dexamethasone on apoptosis of acinar cells in the pancreas of rats with SAP and the protein expression of the apoptosis-regulating genes Bax and Bcl-2. METHODS:Ninety Sprague-Dawley rats with SAP were randomly divided into a model group and a dexamethasone treated group(45 rats in each group),and another 45 rats formed the sham operation group.Survival rates were calculated and gross pathological changes in the pancreas of each group were observed under a light microscope 3,6 and 12 hours after operation.Tissue microarray technology was applied to prepare pancreatic tissue sections.The changes in Bax and Bcl-2 protein expression levels of pancreatic tissues from each group were assessed by immunohistochemical staining,and TUNEL staining was used to evaluate changes in apoptosis index. RESULTS:The model and treated groups did not differ in mortality at each time point.The pathological score for the pancreas in the treated group was significantly lower than that in the model group at 3 and 6 hours.The positive rates of Bax protein expression in the head and tail of the pancreas in the treated group at all time points were all markedly higher than those of the model group. The positive rate of Bcl-2 protein expression in the head of the pancreas in the treated group was significantly higher than that of the model group at 3 hours.TUNEL staining showed that the pancreas head and tail apoptosis indices of the treated group were markedly higher than those of the model group after 6 hours. CONCLUSIONS:Apoptosis may be a protective response to pancreatic cell injury.The mechanism of action of dexamethasone in treating SAP may be related to the apoptosis of acinar cells in the pancreas induced by apoptosis-regulating genes such as Bax and Bcl-2. The advantages of tissue microarrays in pathological examination of the pancreas include saving of time and energy,efficiency and highly representative. | Zhang, Xi-Ping Tian, Hua Lu, Bei Chen, Li Xu, Ru-Jun Wang, Ke-Yi Wang, Zhi-Wei Cheng, Qi-Hui Shen, Hai-Ping | 2007 | Hepatobiliary & Pancreatic Diseases International2007,6,5: | 7 |
| 18 | C-isotope composition and correlation of the Upper Neoproterozoic in Keping area, Xinjiang显示文摘C-isotope analysis of the carbonates in the Upper Neoproterozoic in Keping, Xinjiang indicates that the Qigebrak Formation and the Upper Sugaitbrak Formation mainly record positive C-isotope values, and a distinct positive excursion occurs in the lower part of the Qigebrak Formation. There are three negative excursions in the boundary between the Qigebrak Formation and the Cambrian, the uppermost and lowermost Upper Sugaitbrak Formation. These characters resemble those of the Upper Neoproterozoic in the Three-Gorge area, which suggests that the Upper Sugaitbrak Formation and Qigebrak Formation can be correlated with the middle and upper parts of the Doushantuo Formation and Dengying Formation, respectively. The negative excursion at the top of the Upper Sugaitbrak Formation corresponds to that at the top of the Doushantuo Formation, while the negative excursion at the bottom of the Sugaitbrak Formation can be correlated with that at the middle part of the Doushantuo Formation in the Three-Gorge area and that at the top of the Hangelchaok diamictites in the Quruqtagh area. | HE XiuBin, XU Bei & YUAN ZhiYun The Key Laboratory of Orogenic Belts and Crustal Evolution, Peking University Ministry of Education of China School of Earth and Space Sciences, Peking University, Beijing 100871, China | 2007 | Chinese Science Bulletin2007,52,4: | 7 |
| 19 | Easily manageable prognostic factors in 152 Chinese elderly acute myeloid leukemia patients:a single-center retrospective study显示文摘We retrospectively investigated the prognostic factors of acute myeloid leukemia(AML) in 152 Chinese patients with de novo AML who were older than 60 years of age and who received treatment at our hospital.Log-rank test showed that 6 parameters including older age,higher white blood cell(WBC) counts,lactate dehydrogenase(LDH)and bone marrow(BM) blasts at diagnosis,unfavorable risk cytogenetics,and non-mutated CEBPα were significant adverse prognostic factors of overall survival(OS) for elderly AML patients(P = 0.0013,0.0358,0.0132,0.0242,0.0236 and 0.0130,respectively).Moreover,older age and higher LDH were significant adverse predictors for relapse-free survival(RFS)(P = 0.0447 and 0.0470,respectively).Univariate analysis revealed similar results for OS to those of the log-rank test and only higher LDH at diagnosis was a significant adverse predictor for RFS(P = 0.028,HR:1.979,95%CI:1.075-3.644).In multivariate analysis,we identified 2 trends towards independent prognostic factors for OS,including BM blasts at diagnosis(P = 0.057,HR:1.676,95%CI:0.984-2.854)and mutation status of CEBPα(P = 0.064,HR:4.173,95%CI:0.918-18.966).Our data indicated that older age,gender and a previous history of hematologic diseases resulted in lower complete remission rate(P = 0.012,0.051 and 0.086,respectively).We further developed an easy scoring system for predicting prognosis and response to induction therapy in older AML patients.Patients who had lower scores showed significantly longer OS and RFS(P = 0.0006 and 0.1001,respectively) and higher CR rate(P = 0.014).Our research is limited by its retrospective nature and the results from our study need to be further validated by prospective randomized clinical trials. | Jiadai Xu Tingmei Chen Yun Liu Huayuan Zhu Wei Wu WenYi Shen Bei Xu Sixuan Qian Jianyong Li Peng Liu | 2014 | The Journal of Biomedical Research2014,28,5: | 7 |
| 20 | Rhizosheath formation and involvement in foxtail millet(Setaria italica) root growth under drought stress显示文摘The rhizosheath, a layer of soil particles that adheres firmly to the root surface by a combination of root hairs and mucilage, may improve tolerance to drought stress. Setaria italica(L.) P. Beauv.(foxtail millet), a member of the Poaceae family, is an important food and fodder crop in arid regions and forms a larger rhizosheath under drought conditions. Rhizosheath formation under drought conditions has been studied, but the regulation of root hair growth and rhizosheath size in response to soil moisture remains unclear. To address this question, in this study we monitored root hair growth and rhizosheath development in response to a gradual decline in soil moisture. Here, we determined that a soil moisture level of 10%–14%(w/w)stimulated greater rhizosheath production compared to other soil moisture levels. Root hair density and length also increased at this soil moisture level, which was validated by measurement of the expression of root hair-related genes.These findings contribute to our understanding of rhizosheath formation in response to soil water stress. | Tie-Yuan Liu Nenghui Ye Tao Song Yunying Cao Bei Gao Di Zhang Fuyuan Zhu Moxian Chen Yingjiao Zhang Weifeng Xu Jianhua Zhang | 2019 | Journal of Integrative Plant Biology2019,61,4: | 6 |
