| 4 | Impact 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. | 2008 | World Journal of Gastroenterology2008,14,15: | 31 |

| 7 | Structure and function of aggrecan显示文摘Aggrecan is the major proteoglycan in the articular cartilage. This molecule is important in the proper functioning of articular cartilage because it provides a hydrated gel structure (via its interaction with hyaluronan and link protein) that endows the cartilage with load-bearing properties. It is also crucial in chondroskeletal morphogenesis during development. Aggrecan is a multimodular molecule expressed by chondrocytes. Its core protein is composed of three globular domains (G1, G2, and G3) and a large extended region (CS) between G2 and G3 for glycosaminoglycan chain attachment. G1 comprises the amino terminus of the core protein. This domain has the same structural motif as link protein. Functionally, the G1 domain interacts with hyaluronan acid and link protein, forming stable ternary complexes in the extracellular matrix. G2 is homologous to the tandem repeats of G1 and of link protein and is involved in product processing. G3 makes up the carboxyl terminus of the core protein. It enhances glycosaminoglycan modification and product secretion. Aggrecan plays an important role in mediating chondrocyte-chondrocyte and chondrocyte-matrix interactions through its ability to bind hyaluronan. | CHRIS KIANI, LIWEN CHEN, YAO JIONG WU, ALBERT J YEE, BURTON B YANG, Sunnybrook and Women’s College Health Sciences Centre and Department of Laboratory Medicine and Patobiology, 2 Department of Surgeny, Faculty of Medicine, University of Toronto, Canada | 2002 | Cell Research2002,12,1: | 27 |

| 10 | Changed clinical aspects of primary liver cancer in China during the past 30 years显示文摘BACKGROUND: Primary liver cancer (PLC) is one of the most frequently seen tumors in China. Thirty years ago, patients with PLC were often detected at relatively late stage, with a palpable mass or marked clinical symptoms and poor prognosis. In the past 30 years, the diagnosis and treatment of PLC have been greatly improved with better prognosis. METHODS: In order to study the changes of PLC during the 30 years, the clinical data of 3250 patients with PLC from 10 medical institutions of China were collected, ana- lyzed , and compared with those of 3254 PLC patients be- fore the 30 years. RESULTS: In the 3250 patients aged 1-80 years, with an average age of 49.1 years, the male to female ratio (2.3:1) was lower than that before the 30 years. 73.5% of the 3250 patients sought medical advice within 3 months after the onset of the disease in contrast to 63.8% before the 30 years. Compared with those patients before the 30 years the symptoms and signs were alleviated generally. The HBsAg positive rate was 81.0%, but the HCV-Ab positive rate was 13.2%. The AFP level in 75% of patients was elevated, but in the remaining 25% was normal. 1912 patients (58.8%) were confirmed pathologically. Among them 1755 patients (91.8%) had hepatocellular carcinoma. The overall resec- tion rate was 46.3%. Those who had early, middle, late stage carcinoma accounted for 29.9%, 51.5%, and 18.6%respectively in contrast to 0.4%, 47.0%, and 52.6% repor- ted before the 30 years. The 1-, 3-, 5-year survival rates of the patients were 66.1%, 39.7%, and 32.5% respectively, whereas 93.5%, 70.1%, and 59.1% for the early stage pa- tients, and 65.3%, 30.5%, and 23.5% for the middle stage patients. The half and 1-year survival rates of the late stage patients were 52.5%, and 14.7%, respectively. CONCLUSION: Comparison with the clinical data before and after the 30 years show that PLC can be diagnosed ear- ly. More PLC patients tend to undergo resection while re- ceiving a better conservative treatment, which ensures a prognosis. | Bing-Hui Yang, Jing-Lin Xia, Li-Wen Huang, Zhao-You Tang, Ming-Shan Chen, Jin-Qing Li, An-Min Liang, Qin-Guo Mo, Hui-Shan Lu, Chao-Liu Dai, Lu-Nan Yan, Zhi-Jian Yu, Rong-Sheng Rao, Le-Qun Li, Zhi-Xiong Su, Zhuang-Wei Fang Shanghai, China Liver Cancer Institute & Zhongshan Hospital, Fudan University, Shanghai 200032, China Tumor Hospital, Zhongshan University, Guangzhou 510000, China Tumor Hospital, Guangxi Medical Universi- ty, Nanning 530000, China Xiehe Hospital, Fujian Medical University, Fuzhou 350000, China Second Hos- pital, Chinese Medical University, Shenyang 110000, China Huaxi Hospital, Sichuan University, Chengdu 610041, China Hospital Affiliated to Nantong Medical University, Nantong 226000 , China Second Hospital, Jiangxi Medical University, Nanchang 330000 , China First Hospital Affiliated to Guangxi Medical University, Nanning 530000 , China People’s Hospital of Hainan Province, Haikou 570000, China | 2004 | Hepatobiliary & Pancreatic Diseases International2004,3,2: | 20 |
| 11 | Ten-year survival of hepatocellular carcinoma patients undergoing radiofrequency ablation as a first-line treatment显示文摘AIM: To investigate the long-term survival and prognostic factors in hepatocellular carcinoma(HCC) patients undergoing radiofrequency ablation(RFA) as a first-line treatment.METHODS: From 2000 to 2013, 316 consecutivepatients with 404 HCC(1.0-5.0 cm; mean: 3.2 ± 1.1 cm) underwent ultrasonography-guided percutaneous RFA as a first-line treatment. There were 250 males and 66 females with an average age of 60.1 ± 10.8 years(24-87 years). Patients were followed for 1 year to > 10 years after RFA(234, 181, 136, and 71 for 3, 5, 7, and 10 years, respectively). Overall local response rates and long-term survival rates were assessed. Survival results were generated using Kaplan-Meier estimates, and multivariate analysis was performed using the Cox regression model. RESULTS: In total, 548 RFA sessions were performed and major complications occurred in 10 sessions(1.8%). Local tumor progression and/or new tumor development were observed in 43.3%(132/305) of the patients during the follow-up period. Overall 5-and 10-year survival rates were 49.7% and 28.4%, respectively. Based on multivariate analysis, three factors were identified as independent prognostic factors for overall survival: Child-Pugh classification(HR = 4.054, P < 0.001), portal vein hypertension(HR = 2.743, P = 0.002), and tumor number(HR = 2.693, P = 0.003). The local progression-free 5- and 10-year survival rates were 42.7% and 19.5%. In addition to the Child-Pugh classification and the number of tumors, the number of RFA sessions(HR = 1.550, P = 0.002) was associated with local progression-free survival.CONCLUSION: RFA can achieve acceptable outcomes for HCC patients as a first-line treatment, especially for patients with Child-Pugh class A, patients with a single tumor and patients without portal vein hypertension. | Wei Yang Kun Yan S Nahum Goldberg Muneeb Ahmed Jung-Chieh Lee Wei Wu Zhong-Yi Zhang Song Wang Min-Hua Chen | 2016 | World Journal of Gastroenterology2016,22,10: | 20 |

| 13 | Extraction and purification of TGFβ and its effect on the induction of apoptosis of hepatocytes显示文摘AIM To extract and purify the transforming growth factor β (TGF β), and to demonstrate its biological activity in vivo and induction of apoptosis of hepatocytes in vitro.METHODS TGF β was isolated from fresh bovine platelets by acid/ethanol extraction method and purified with ion exchange and gel chromatography. The extracted TGF β was injected subcutaneously to mice, and its biological activity in vivo was observed 72 hfs post-injection by HE staining. The morphological changes were observed by HE staining and the occurrence of apoptosis was detected by TUNEL method after the human normal hepatic cell line QZG was treated with 8 μg@L 1 TGFβ for 12 hrs in vitro.RESULTS The molecular mass 25 ku TGF β protein was successfully extracted. It was able to induce localized granulation tissue formation in vivo. TGF β-treated hepatocytes showed obvious apoptotic morphological changes, including the pyknosis and dense-stained nuclei and cytoplasm, the fragmentary, annular or crescent nuclei, and the 'bubbling' cytoplasm. Moreover, its apoptotic rate was significantly higher than that of the control group (P<0.05).CONCLUSION Biological active TGF β protein is extracted and purified successfully from bovine platelets, and it is able to induce the apoptosis of hepatocytes. | Xiao-Hui Si Lian-Jun Yang Research Institute of Stomatology,the Ninth People’s Hospital,Shanghai Second Medical University,Shanghai 200011,ChinaDepartment of Pathology,Fourth Military Medical University,Xi’an 710033,Shaanxi Province,China | 2001 | World Journal of Gastroenterology2001,7,4: | 15 |

| 16 | The enhanced X-ray Timing and Polarimetry mission—eXTP显示文摘In this paper we present the enhanced X-ray Timing and Polarimetry mission—eXTP. eXTP is a space science mission designed to study fundamental physics under extreme conditions of density, gravity and magnetism. The mission aims at determining the equation of state of matter at supra-nuclear density, measuring effects of QED, and understanding the dynamics of matter in strong-field gravity. In addition to investigating fundamental physics, eXTP will be a very powerful observatory for astrophysics that will provide observations of unprecedented quality on a variety of galactic and extragalactic objects. In particular, its wide field monitoring capabilities will be highly instrumental to detect the electro-magnetic counterparts of gravitational wave sources.The paper provides a detailed description of:(1) the technological and technical aspects, and the expected performance of the instruments of the scientific payload;(2) the elements and functions of the mission, from the spacecraft to the ground segment. | ShuangNan Zhang Andrea Santangelo Marco Feroci YuPeng Xu FangJun Lu Yong Chen Hua Feng Shu Zhang Sφren Brandt Margarita Hernanz Luca Baldini Enrico Bozzo Riccardo Campana Alessandra De Rosa YongWei Dong Yuri Evangelista Vladimir Karas Norbert Meidinger Aline Meuris Kirpal Nandra Teng Pan Giovanni Pareschi Piotr Orleanski QiuShi Huang Stephane Schanne Giorgia Sironi Daniele Spiga Jiri Svoboda Gianpiero Tagliaferri Christoph Tenzer Andrea Vacchi Silvia Zane Dave Walton ZhanShan Wang Berend Winter Xin Wu Jean J.M.in't Zand Mahdi Ahangarianabhari Giovanni Ambrosi Filippo Ambrosino Marco Barbera Stefano Basso Jörg Bayer Ronaldo Bellazzini Pierluigi Bellutti Bruna Bertucci Giuseppe Bertuccio Giacomo Borghi XueLei Cao Franck Cadoux Francesco Ceraudo TianXiang Chen Yu Peng Chen Jerome Chevenez Marta Civitani Wei Cui WeiWei Cui Thomas Dauser Ettore Del Monte Sergio Di Cosimo Sebastian Diebold Victor Doroshenko Michal Dovciak YuanYuan Du Lorenzo Ducci QingMei Fan Yannick Favre Fabio Fuschino JoséLuis Ga'lvez Min Gao MingYu Ge Olivier Gevin Marco Grassi QuanYing Gu YuDong Gu DaWei Han Bin Hong Wei Hu Long Ji ShuMei Jia WeiChun Jiang Thomas Kennedy Ingo Kreykenbohm Irfan Kuvvetli Claudio Labanti Luca Latronico Gang Li MaoShun Li Xian Li Wei Li ZhengWei Li Olivier Limousin HongWei Liu XiaoJing Liu Bo Lu Tao Luo Daniele Macera Piero Malcovati Adrian Martindale Malgorzata Michalska Bin Meng Massimo Minuti Alfredo Morbidini Fabio Muleri Stephane Paltani Emanuele Perinati Antonino Picciotto Claudio Piemonte JinLu Qu Alexandre Rachevski Irina Rashevskaya Jerome Rodriguez Thomas Schanz ZhengXiang Shen LiZhi Sheng JiangBo Song LiMing Song Carmelo Sgro Liang Sun Ying Tan Phil Uttley Bo Wang DianLong Wang GuoFeng Wang Juan Wang LangPing Wang YuSa Wang Anna L.Watts XiangYang Wen Jörn Wilms ShaoLin Xiong JiaWei Yang Sheng Yang YanJi Yang Nian Yu WenDa Zhang Gianluigi Zampa Nicola Zampa Andrzej A.Zdziarski AiMei Zhang ChengMo Zhang Fan Zhang Long Zhang Tong Zhang Yi Zhang XiaoLi Zhang ZiLiang Zhang BaoSheng Zhao ShiJie Zheng Yu Peng Zhou Nicola Zorzi J.Frans Zwart | 2019 | Science China(Physics,Mechanics & Astronomy)2019,62,2: | 11 |
| 17 | Hepatitis C virus infection down-regulates the expression of peroxisome proliferator-activated receptor a and carnitine palmitoyl acyl-CoA transferase 1A显示文摘AIM: To elucidate the role of the peroxisome proliferator-activated receptor α (PPARα) and its target gene carnitine palmitoyl acyl-CoA transferase 1A (CPT1A)in the pathogenesis of hepatitis C virus (HCV) infection.METHODS: Liver samples were collected from the patients with chronic HCV infection and controls. HepG2cells were transfected with vector pEF352neo carrying.Two independent clones (clone N3 and N4) stably expressing HCV core protein were analyzed. Total RNA was extracted from cells and liver tissues. PPARα and CPT1A mRNAs were quantified by real-time polymerase chain reaction (PCR) using SYBR Green Master. Total extracted proteins were separated by polyacrylamide gel electrophoresis, and electroblotted. Membranes were incubated with the anti-PPARα antibody, then with a swine anti-rabbit IgG conjugated to horseradish peroxidase for PPARα. Protein bands were revealed by an enhanced chemiluminescence reaction for PPARα. For immunohistochemical staining of PPARα, sections were incubated with the primary goat polyclonal antibody directed against PPARα at room temperature.RESULTS: Real-time PCR indicated that the PPARα level and expression level of CPT1A gene in hepatitis C patients lowered significantly as compared with the controls (1.8±2.8 vs 13±3.4, P = 0.0002; 1.1±1.5 vs 7.4+1, ,P = 0.004). Western blot results showed that the level of PPARα protein in the livers of hepatitis C patients was lower than that in controls (2.3±0.3 vs 3.6±0.2,P = 0.009). The immunohistochemical staining results in chronic hepatitis C patients indicated a decrease in PPARα staining in hepatocytes compared with those in the control livers. The in vitro studies found that in the N3 and N4 colon stably expressing HCV core protein, the PPARα mRNA levels were significantly lower than that in the controls.CONCLUSION: The impaired intrahepatic PPARα expression is associated with the pathogenic mechanism in hepatic injury during chronic HCV infection. HCV infection reduced the expression of PPARα and CPT1A at the level of not only mRNAs but also proteins. PPARα plays an important role in the pathogenesis of chronic HCV infection, but the impaired function of this nuclear receptor in HCV infection needs further studies. | Yang Cheng Sébastien Dharancy Mathilde Malapel Pierre Desreumaux | 2005 | World Journal of Gastroenterology2005,11,48: | 11 |
| 18 | Metformin does not improve survival in patients with hepatocellular carcinoma显示文摘AIM:To assess whether metformin,which has a chemopreventive effect in chronic liver disease,has any chemotherapeutic effect in hepatocellular carcinoma.METHODS:This was a retrospective study of 701 patients with newly diagnosed hepatocellular carcinoma(HCC)seen between January 2005 and June 2011 at Mayo Clinic,Rochester,Minnesota.This patient cohort was a part of the global HCC BRIDGE study,which is a large longitudinal study of HCC determining the realworld experience of HCC characteristics,management and patient outcomes.We defined significant metformin exposure as continuation of this agent at least 90d beyond diagnosis of HCC,and compared survival of diabetic patients on metformin to diabetic patients not on metformin and non-diabetics.RESULTS:Our cohort was 72.9%male,with a mean±SD age of 62.6±12.3 years.The most common etiologies of liver disease were hepatitis C(34%),alcoholic liver disease(29%),fatty liver disease(15%)and hepatitis B(9%).By univariate analysis,using diabetics not on metformin as the reference group,diabetic patients with HCC on metformin had no survival advantage,with a HR(95%CI)of 1.0(0.8-1.3).Non-diabetic HCC patients also did not appear to have a survival advantage as compared to diabetic HCC patients not on metformin,as demonstrated by a HR(95%CI)of1.1(0.7-1.7).Diabetics on metformin beyond 90 d after HCC diagnosis had a longer median survival at 34.2 mo,as compared to 25.5 mo among diabetic patients who were not on metformin or had discontinued metformin within 90 d after HCC diagnosis.This finding was likely due to potential survival bias among those who lived long enough to receive metformin.CONCLUSION:Although the literature suggests a chemotherapeutic effect in other malignancies,our study demonstrates no survival benefit to the use of metformin in diabetic patients with HCC. | Mamatha Bhat Roongruedee Chaiteerakij William S Harmsen Cathy D Schleck Ju Dong Yang Nasra H Giama Terry M Therneau Gregory J Gores Lewis R Roberts | 2014 | World Journal of Gastroenterology2014,20,42: | 11 |
| 19 | Arsenic trioxide promotes mitochondrial DNA mutation and cell apoptosis in primary APL cells and NB4 cell lines显示文摘This study aimed to investigate the effects of arsenic trioxide(As2O3) on the mitochondrial DNA(mtDNA) of acute promyelocytic leukemia(APL) cells.The NB4 cell line was treated with 2.0 μmol/L As2O3 in vitro,and the primary APL cells were treated with 2.0 μmol/L As2O3 in vitro and 0.16 mg kg-1 d-1 As2O3 in vivo.The mitochondrial DNA of all the cells above was amplified by PCR,directly sequenced and analyzed by Sequence Navigatore and Factura software.The apoptosis rates were assayed by flow cytometry.Mitochondrial DNA mutation in the D-loop region was found in NB4 and APL cells before As2O3 use,but the mutation spots were remarkably increased after As2O3 treatment,which was positively correlated to the rates of cellular apoptosis,the correlation coefficient:rNB4-As2O3=0.973818,and rAPL-As2O3=0.934703.The mutation types include transition,transversion,codon insertion or deletion,and the mutation spots in all samples were not constant and regular.It is revealed that As2O3 aggravates mtDNA mutation in the D-loop region of acute promyelocytic leukemia cells both in vitro and in vivo.Mitochondrial DNA might be one of the targets of As2O3 in APL treatment. | MENG Ran1,ZHOU Jin2,SUI Meng3,LI ZhiYong4,FENG GuoSheng1 & YANG BaoFeng2 1 Division of Neurology,the Ninth Clinical Medical College of Beijing University(Shijitan Hospital),Beijing 100038,China 2 The First Hospital of Harbin Medical University,Harbin 150001,China 3 Management Information System,University of International Business and Economics,Beijing 100029,China 4 Department of Radiology,Cambridge University Hospitals NHS Foundation Trust Box 219 Level 5,Addenbrooke’s Hospital Cambridge CB2 0QQ,UK | 2010 | Science China(Life Sciences)2010,53,1: | 10 |
| 20 | Current status of intravenous tissue plasminogen activator dosage for acute ischaemic stroke:an updated systematic review显示文摘The optimal dose of recombinant tissue plasminogen activator(rtPA)for acute ischaemic stroke(AIS)remains controversial,especially in Asian countries.We aimed to update the evidence regarding the use of low-dose versus standard-dose rtPA.We performed a systematic literature search across MEDLINE,Embase,Cochrane Central Register of Controlled Trials(CENTRAL),PsycINFO and Cumulative Index to Nursing and Allied Health Literature(CINAHL)from inception to 22 August 2016 to identify all related studies.The outcomes were death or disability(defined by modified Rankin Scale 2-6),death,and symptomatic intracerebral haemorrhage(sICH).Where possible,data were pooled for meta-analysis with ORs and corresponding 95% CIs by means of random-effects or fixed-effects meta-analysis.We included 26 observational studies and 1 randomised controlled trial with a total of 23210 patients.Variable doses of rtPA were used for thrombolysis of AIS in Asia.Meta-analysis shows that low-dose rtPA was not associated with increased risk of death or disability(OR 1.13,95% CI 0.95 to 1.33),or death(OR 0.86,95% CI 0.74 to 1.01),or decreased risk of sICH(OR 1.06,95% CI 0.65 to 1.72).The results remained consistent when sensitivity analyses were performed including only low-dose and standard-dose rtPA or only Asian studies.Our review shows small difference between the outcomes or the risk profile in the studies using low-dose and/or standard-dose rtPA for AIS.Low-dose rtPA was not associated with lower risk of death or disability,death alone,or sICH. | Xia Wang Shoujiang You Shoichiro Sato Jie Yang Cheryl Carcel Danni Zheng Sohei Yoshimura Craig S Anderson Else Charlotte Sandset Thompson Robinson John Chalmers Vijay K Sharma | 2018 | Stroke & Vascular Neurology2018,3,1: | 10 |
