The consensus included the pathological diagnosis,recurrence risk classification evaluation, targeted agent therapy, surgery and principles of surveillance of GIST. | jian li yingjiang ye jian wang bo zhang shukui qin yingqiang shi yulong he xiaobo liang xiufeng liu ye zhou xin wu xinhua zhang ming wang zhidong gao tianlong lin hui cao lin shen | 2017 | Chinese Journal of Cancer Research2017，29，4： | 104 |
| 2 | Effects of AT1 receptor antagonist,Iosartan,on rat hepatic fibrosis induced by CCl_4显示文摘AIM To investigate effect of losartan,an AT1receptor antagonist,on hepatic fibrosis induced byCCl;and to determine whether or not AT1receptors are expressed on hepatic stellate cells,METHODS AND RESULTS Fifty male Sprague-Dawley rats,weighing(180±20)g,wererandomized into five groups(control group,modelgroup,and three losartan treated groups),inwhich all rats were given the subcutaneousinjection of 40% CCl4(every 3 days for 6 weeks)except for rats of control group.Rats of losartan-treated groups were treated with losartan(20 mg/kg,10 mg/kg,5 mg/kg,daily gavage),After 6weeks liver tissue and serum samples of all ratswere examined.Serum hyaluronic acid(HA),procollagen typeⅢ(PCⅢ)were detected byradioimmunoassays,van Giesion collagen stainingwas used to evaluate the extracellular matrix of ratswith liver fibrosis.The expression of AT1receptors,transforming growth factor-beta(TGF-β),and alpha-smooth muscle actin(a-SMA)inliver tissue were determined byimmunohistochemical techniques.Compared withmodel group,serum ALT and AST of losartan-treated groups were significantly reduced(t=4.20,P<0.01 and t=4.57,P<0.01).Serum HAand PCⅢalso had significant differences(t=3.53,P<0.01 and t=2.20,P<0.05).Thedegree of fibrosis was improved by losartan and correlated with the expressions of AT1 receptors,TGF-β,and α-SMA in liver tissue.CONCLUSION AT1 receptor antagonist,losartan,could limit the progression of the hepatic fibrosisinduced by CCl4.The mechanism may be related tothe decrease in the expression of AT1 receptorsand TGF-β,ameliorating the injury of hepatocytes;activation of local renin-angiotensin system mightrelate to hepatic fibrosis;and during progressionof fibrosis,activated hepatic stellate cells mightexpress AT1 receptors. | Hong Shan Wei Ding Guo Li Han Ming Lu Yu Tao Zhan Zhi Rong Wang Xin Huang Jing Zhang Ji Lin Cheng Qin Fang Xu Department of Gastroenterology,Xinhua Hospital,Shanghai Second Medical University,Shanghai 200092,China | 2000 | World Journal of Gastroenterology2000，6，4： | 42 |
| 3 | Prognostic value of systemic immune.inflammation index in patients with gastric cancer显示文摘Background:Inflammation-based indexes have been used to predict survival and recurrence in cancer patients.Systemic immune-inflammation index(Sll) was reported to be associated with prognosis in some malignant tumors.In the present study,we aimed to explore the association between Sll and the prognosis of patients with gastric cancer.Methods:We retrospectively analyzed data from 444 gastric cancer patients who underwent gastrectomy at the First Affiliated Hospital of Sun Yat-sen University between January 1994 and December 2005.Preoperative Sll was calculated.The Chi square test or Fisher's exact test was used to determine the relationship between preoperative Sll and clinicopathologic characteristics.Overall survival(OS) rates were estimated using the Kaplan-Meier method,and the effect of Sll on OS was analyzed using the Cox proportional hazards model.Receiver operating characteristic(ROC)curves were used to compare the predictive ability of Sll,NLR,and PLR.Results:Sll equal to or higher than 660 was significantly associated with old age,large tumor size,unfavorable Borrmann classification,advanced tumor invasion,lymph node metastasis,distant metastasis,advanced TNM stage,and high carcino-embryonic antigen level,high neutrophil-lymphocyte ratio,and high platelet-lymphocyte ratio(all P<0.05).High Sll was significantly associated with unfavorable prognosis(P<0.001) and Sll was an independent predictor for OS(P=0.015).Subgroups analysis further showed significant associations between high Sll and short OS in stage Ⅰ,Ⅱ,Ⅲ subgroups(all P<0.05).Sll was superior to NLR and PLR for predicting OS in patients with gastric cancer.Conclusion:Preoperative Sll level is an independent prognostic factor for OS in patients with gastric cancer. | Kang Wang Feiyu Diao Zhijun Ye Xinhua Zhang Ertao Zhai Hui Ren Tong Li Hui Wu Yulong He Shirong Cai Jianhui Chen | 2017 | Chinese Journal of Cancer2017，36，9： | 30 |
| 4 | Chronic Hepatitis B Infection with Low Level Viremia Correlates with the Progression of the Liver Disease显示文摘Background and Aims:Currently,insufficient clinical data are available to address whether low-level viremia(LLV)observed during antiviral treatment will adversely affect the clinical outcome or whether treatment strategies should be altered if LLV occurs.This study compared the clinical out-comes of patients with a maintained virological response(MVR)and patients who experienced LLV and their treatment strategies.Methods:A retrospective cohort of 674 patients with chronic hepatitis B virus(HBV)infection who received antiviral treatment for more than 12 months was analyzed for the development of end-stage liver disease and treatment strategies during the follow-up period.End-stage liver disease included decompensated liver cirrhosis and hepatocellular carcinoma(HCC).Results:During a median 42-month follow-up,end-stage liver disease developed more frequently in patients who experienced LLV than in those who experienced MVR(7.73%and 15.85%vs.0.77%and 5.52%at 5 and 10 years,respectively;p=0.000).The trend was consistent after propensity score matching.In the high-risk group of four HCC risk models,LLV patients had a higher risk of HCC development(p<0.05).By Cox proportional hazard model analysis,LLV was an independent risk factor for end-stage liver disease and HCC(hazard ratio[HR]=6.280,confidence interval[CI]=2.081-18.951,p=0.001;HR=5.108,CI=1.392-18.737,respectively;p=0.014).Patients achieved a lower rate of end-stage liver disease by adjusting treatment compared to continuing the original treatment once LLV occurred(p<0.05).Conclusions:LLV is an independent risk factor for end-stage liver disease and HCC,and treatment adjustments can be considered. | Qian Zhang Hong Peng Xiaoqing Liu Huimin Wang Jinjie Du Xinhua Luo Hong Ren Peng Hu | 2021 | Journal of Clinical and Translational Hepatology2021，9，6： | 25 |
| 5 | The recommendations of Chinese Parkinson’s disease and movement disorder society consensus on therapeutic management of Parkinson’s disease显示文摘Background:Parkinson’s disease(PD)is a chronic,progressive and debilitating disease,which affects over 2.5 million people in China.PD is characterized clinically by resting tremor,muscular rigidity,bradykinesia and postural instability.As the disease progresses,additional complications can arise such as non-motor and neurobehavioral symptoms.Pharmacological treatment and surgical intervention for PD have been implemented in China.Until 10 years ago,there was lack of standardization for the management of PD in different regions and among different physicians,leading to different treatment levels in different regions and different physicians.Since then,the Chinese Parkinson’s Disease and Movement Disorder Society have published three versions of guidelines for the management of PD in China,in 2006,2009 and 2014,respectively.Correspondingly,the overall level of treatment for PD in China improved.Objectives:To update the treatment guidelines based on current foreign and domestic practice guidelines and clinical evidence,and to improve the treatment options available to physicians in the management of PD.Summary:A variety of treatment recommendations in the treatment guidelines have been proposed,including physical activity and disease-modifying medication,which should be initiated at the early-stage of the disease.The principles of dosage titration should be followed to avoid acute adverse reactions to the drugs,to achieve a satisfactory clinical effect with a low dose and to reduce the incidence of long-term motor complications.Moreover,different treatment strategies should be considered at different stages of the disease.Importantly,treatment guidelines and personalized treatments should be valued equally.A set of treatment recommendations has been developed to assist physicians to improve and optimize clinical outcomes for patients with PD in China. | Shengdi Chen Piu Chan Shenggang Sun Haibo Chen Baorong Zhang Weidong Le Chunfeng Liu Guoguang Peng Beisha Tang Lijuan Wang Yan Cheng Ming Shao Zhenguo Liu Zhenfu Wang Xiaochun Chen Mingwei Wang Xinhua Wan Huifang Shang Yiming Liu Pingyi Xu Jian Wang Tao Feng Xianwen Chen Xingyue Hu Anmu Xie Qin Xiao | 2016 | Translational Neurodegeneration2016，5，1： | 23 |

| 7 | A review of ecological restoration techniques in fluvial rivers显示文摘Rivers play an important role in people's living and agricultural production,however,intense human activities have broken the original ecological balance,and affected structures and functions of the river ecosystem.To restore the damaged river ecosystem back to a healthy status,effective ecological restoration measures need to be implemented.The main problems that the damaged rivers face are either the locally altered hydrological processes affected by construction of hydraulic facilities,or the deterioration of water quality resulted from pollution emissions,or both.In this study,ecological restoration techniques of the rivers affected by engineering control or pollution are reviewed respectively.In addition,three kinds of methods,i.e.physical,chemical and biological-ecological methods are introduced in details for the rivers affected by water pollution.At present,the development of river restoration techniques shows the following trends:1) the scale of ecological restoration is becoming larger;2) ecological restoration measures are required to meet multiple objectives;and 3) the management of water environment is changing from water quality management to aquatic ecosystem management. | Baozhu Pan Jianping Yuan Xinhua Zhang Zhaoyin Wang Jiao Chen Jinyou Lu Wenjun Yang Zhiwei Li Na Zhao Mengzhen Xu | 2016 | International Journal of Sediment Research2016，31，2： | 18 |
| 8 | Bi_(2)S_(3) Nanostructures: A New Photocatalyst显示文摘Uniform colloidal Bi_(2)S_(3) nanodots and nanorods with different sizes have been prepared in a controllable manner via a hot injection method. X-ray diffraction (XRD) results show that the resulting nanocrystals have an orthorhombic structure. Both the diameter and length of the nanorods increase with increasing concentration of the precursors. All of the prepared Bi_(2)S_(3) nanostructures show high efficiency in the photodegradation of rhodamine B, especially in the case of small sized nanodots-which is possibly due to their high surface area. The dynamics of the photocatalysis is also discussed. | Tong Wu Xinggui Zhou Hua Zhang Xinhua Zhong | 2010 | Nano Research2010，3，5： | 18 |

| 12 | An Estimation of Internal Soliton Forces on a Pile in the Ocean显示文摘Internal soliton forces on oil-platform piles in the ocean are estimated with the Morison Formula. Different from sur- face wave forces, which change only in magnitude along a pile, internal soliton forces can be distributed over the entire pile in the water and they change not only in magnitude but also in direction with depth. Our calculations show that the maximum total force caused by a soliton with its associated current of 2.1 m s-1 is nearly equal to the maximum total force exerted by a surface wave with a wavelength of 300 m and a wave-height of 18 m. The total internal soliton force is large enough to affect the operations of marine oil platforms and other facilities. Therefore, the influence of internal solitons should not be neglected in the design of oil platforms. | DU Tao SUN Li ZHANG Yijun BAO Xianwen FANG Xinhua | 2007 | Journal of Ocean University of China2007，6，2： | 12 |

| 15 | Direction of arrival estimation and signal recovery based on single snapshot compressed sensing in frequency domain显示文摘Direction of arrival(DOA) estimation and signal recovery is the base of the underwater target localization,tracking and recognition.Based on the compressed sensing theory,a method for DOA estimation and source signal recovery is proposed using the single snapshot processing of the received array signal in frequency domain.The received array signal are transformed to frequency domain,and the single snapshot data in frequency domain are regarded as the measured data of the compressed sensing.According to the frequency,searching orientation and array manifold,the overcomplete array manifold is constructed as the sensing matrix of the compressed sensing.Both the target signal and power of the searching orientation are estimated by the basis pursuit method to complete DOA estimation and signal recovery.Simulation results show that the proposed method has a number of advantages over the minimum variance distortionless response(MVDR) method,including improved robustness to noise,fewer requirement in number of sensors and snapshots.And the correlation coefficient of the signal reaches up to 0.89.Experiment results in real environments verify that the proposed method performs more effectively in the detection of weak targets than the MVDR method and can be applied to real sonar system. | KANG Chunyu LI Qianyan ZHANG Xinhua LI Jun | 2016 | Chinese Journal of Acoustics2016，35，2： | 10 |
| 16 | Estimation of inbreeding and identification of regions under heavy selection based on runs of homozygosity in a Large White pig population显示文摘Background: Runs of homozygosity(ROHs) are homozygous segments of the genome where the two haplotypes inherited from the parents are identical. The current availability of genotypes for a very large number of single nucleotide polymorphisms(SNPs) is leading to more accurate characterization of ROHs in the whole genome. Here,we investigated the occurrence and distribution of ROHs in 3,692 Large White pigs and compared estimates of inbreeding coefficients calculated based on ROHs(FROH), homozygosity(FHOM), genomic relationship matrix(FGRM)and pedigree(FPED). Furthermore, we identified genomic regions with high ROH frequencies and annotated their candidate genes.Results: In total, 176,182 ROHs were identified from 3,569 animals, and all individuals displayed at least one ROH longer than 1 Mb. The ROHs identified were unevenly distributed on the autosomes. The highest and lowest coverages of Sus scrofa chromosomes(SSC) by ROH were on SSC14 and SSC13, respectively. The highest pairwise correlation among the different inbreeding coefficient estimates was 0.95 between FROH_totaland FHOM, while the lowest was-0.083 between FGRMand FPED. The correlations between FPEDand FROHusing four classes of ROH lengths ranged from 0.18 to 0.37 and increased with increasing ROH length, except for ROH > 10 Mb. Twelve ROH islands were located on four chromosomes(SSC1, 4, 6 and 14). These ROH islands harboured genes associated with reproduction, muscular development, fat deposition and adaptation, such as SIRT1, MYPN, SETDB1 and PSMD4.Conclusion: FROHcan be used to accurately assess individual inbreeding levels compared to other inbreeding coefficient estimators. In the absence of pedigree records, FROHcan provide an alternative to inbreeding estimates.Our findings can be used not only to effectively increase the response to selection by appropriately managing the rate of inbreeding and minimizing the negative effects of inbreeding depression but also to help detect genomic regions with an effect on traits under selection. | Liangyu Shi Ligang Wang Jiaxin Liu Tianyu Deng Hua Yan Longchao Zhang Xin Liu Hongmei Gao Xinhua Hou Lixian Wang Fuping Zhao | 2020 | Journal of Animal Science and Biotechnology2020，11，4： | 10 |
| 17 | Deformation of freezing water droplets on a cold copper surface显示文摘Freezing processes of water and peanut oil droplets on a cold surface are investigated in this paper. We observed during our experiments that the base surface of a water droplet that is in direct contact with the cold surface keeps its original shape, but the other part of the droplet shows an obvious growth along the direction normal to the base surface. One small protrusion appears on the top of the water droplet at the end of the freezing process. The experimental observations also show that no obvious shape change happens during the freezing of peanut oil droplets. It is postulated that the effects of sur- face tension and volume dilatation resulted from liquid-to-solid phase change cause the shape change and protrusions formation. Based on this postulation, a physical and mathematical model is developed. The results of the model of a water droplet’s freezing process correspond with our experimental observations. The observed phenomenon that frost-growth speed on the protrusion is higher than that on the other part of the water droplet is also analyzed. | WANG Jieteng LIU Zhongliang GOU Yujun ZHANG Xinhua CHENG Shuiyuan | 2006 | Science China(Technological Sciences)2006，49，5： | 9 |
| 18 | Comparison of sentinel lymph node detection performances using blue dye in conjunction with indocyanine green or radioisotope in breast cancer patients: a prospective singlecenter randomized study显示文摘Objective:This randomized study aimed to compare the clinical efficacy between the novel dual tracer composed of indocyanine green(ICG)and blue dye(BD)and the conventional dual tracer composed of radioisotope and BD for sentinel lymph node(SLN)mapping in patients with breast cancer.Methods:This study enrolled 471 clinically lymph node-negative patients with primary breast cancer.All patients underwent mastectomy,and those undergoing sentinel lymph node biopsy(SLNB)were randomized to receive blue dye plus radioisotope(RB group)or BD plus ICG(IB group).The detection performances on SLN identification rate,positive SLN counts,detection sensitivity,and false-negative rate were compared between the two groups.Results:In the IB group,97%(194/200)of the patients who underwent the ICG and BD dual tracer injection showed fluorescentpositive lymphatic vessels within 2–5 min.The identification rate of SLNs was comparable between the IB group(99.0%,198/200)and the RB group(99.6%,270/271)(P=0.79).No significant differences were observed in the identification rate of metastatic SLNs(22.5%vs.22.9%,P>0.05,RB group vs.IB group,the same below),positive SLN counts(3.72±2.28 vs.3.91±2.13,P>0.05),positive metastatic SLN counts(0.38±0.84 vs.0.34±0.78,P>0.05),SLNB detection sensitivity(94.4%vs.92.5%,P>0.05),or false-negative rate(5.6%vs.7.5%,P>0.05)between the two groups.Conclusions:ICG can be used as a promising alternative tracer for radioisotope in SLN mapping,and when it is combined with BD in lymphangiography,it offers comparable detection sensitivity compared to the conventional lymphatic mapping strategies that are widely used in clinical practice. | Long Yuan Xiaowei Qi Yi Zhang Xinhua Yang Fan Zhang Linjun Fan Li Chen Kongyong Zhang Ling Zhong Yanling Li Sijie Gan Wenying Fu Jun Jiang | 2018 | Cancer Biology & Medicine2018，15，4： | 9 |
| 19 | Biodegradable Zn-Sr alloy for bone regeneration in rat femoral condyle defect model: In vitro and in vivo studies显示文摘Bone defects are commonly caused by severe trauma,malignant tumors,or congenital diseases and remain among the toughest clinical problems faced by orthopedic surgeons,especially when of critical size.Biodegradable zinc-based metals have recently gained popularity for their desirable biocompatibility,suitable degradation rate,and favorable osteogenesis-promoting properties.The biphasic activity of Sr promotes osteogenesis and inhibits osteoclastogenesis,which imparts Zn-Sr alloys with the ideal theoretical osteogenic properties.Herein,a biodegradable Zn-Sr binary alloy system was fabricated.The cytocompatibility and osteogenesis of the Zn-Sr alloys were significantly better than those of pure Zn in MC3T3-E1 cells.RNA-sequencing illustrated that the Zn-0.8Sr alloy promoted osteogenesis by activating the wnt/β-catenin,PI3K/Akt,and MAPK/Erk signaling pathways.Furthermore,rat femoral condyle defects were repaired using Zn-0.8Sr alloy scaffolds,with pure Ti as a control.The scaffold-bone integration and bone ingrowth confirmed the favorable in vivo repair properties of the Zn-Sr alloy,which was verified to offer satisfactory biosafety based on the hematoxylin-eosin(H&E)staining and ion concentration testing of important organs.The Zn-0.8Sr alloy was identified as an ideal bone repair material candidate,especially for application in critical-sized defects on load-bearing sites due to its favorable biocompatibility and osteogenic properties in vitro and in vivo. | Bo Jia Hongtao Yang Zechuan Zhang Xinhua Qu Xiufeng Jia Qiang Wu Yu Han Yufeng Zheng Kerong Dai | 2021 | Bioactive Materials2021，6，6： | 9 |
| 20 | Effects of High-temperature Char Layer and Pyrolysis Gas on NOx Reduction in a Typical Decoupling Combustion Coal-fired Stove显示文摘The suppression of nitrogen oxides(NO_x) is the key to reducing pollutant emission of a domestic coal-fired stove due to the limitation of technology condition and economic cost. The decoupling combustion(DC) technology invented by Institute of Process Engineering(IPE), Chinese Academy of Sciences(CAS) is characterized by that a traditional stove is separated into a pyrolysis and a combustion chamber as well as a bottom passage between them. In this study, the combustion of briquette from bituminous coal in different operation modes in a typical decoupling stove is tested and simulated to validate the advantage of DC technology over so-called reverse combustion. The smokeless and high-efficiency combustion of bituminous briquette with low emissions of NO_x and CO can be implemented by utilizing low NO_x combustion under low temperature and reduction atmosphere in the pyrolysis chamber as well as after-combustion of char and pyrolysis gas under high temperature and oxidation atmosphere in the combustion chamber. The effects of the main reducing components in pyrolysis gas as well as char on NO_x reduction were numerically investigated in this study, which shows that the reducing ability increases gradually from CH_4, CO to char, but the combined reducing ability of them cannot be determined by a simple addition. | LI Honglin HAN Jian ZHANG Nan LIU Xinhua HE Jingdong DU Wei | 2019 | Journal of Thermal Science2019，28，1： | 8 |
