| 2 | Inhibiting effect of antisense oligonucleotides phosphorthioate on gene expression of TIMP-1 in rat liver fibrosis显示文摘AIM To observe the inhibition of antisenseoligonucleotides (asON) phosphorthioate to thetissue inhibitors metalloproteinase-1 (TIMP-1)gene and protein expression in the liver tissue ofimmunologically induced hepatic fibrosis rats.The possibility of reversing hepatic fibrosisthrough gene therapy was observed.METHODS Human serum albumin (HSA) wasused to attack rats, as hepatic fibrosis model, inwhich asONs were used to block the gene andprotein expressing TIMP-1. According to theanalysis of modulator, structure protein, codingseries of TIMP-1 genome, we designed fourdifferent asONs. These asONs were injected intothe hepatic fibrosis models through coccygealvein. The results was observed by RT-PCR formeasuring TIMP-1 mRNA expression,immunohistochemistry and in situ hybridizationfor collagen Ⅰ, Ⅲ, special staining of collagenfiber, and electron microscopic examination.RESULTS Hepatic fibrosis could last within 363days in our modified model. The expressinglevel of TIMP-1 was high during hepatic fibrosisprocess. It has been proved by theimmunohistochemical and the electronmicroscopic examination that the asONphosphorthioate of TIMP-1 could exactly expressin vivo. The effect of colchicine wasdemonstrated to inhibit the expressing level ofmRNA and the content of collagen Ⅰ, Ⅲ in theliver of experimental hepatic fibrosis rats.However, the electron microscopy research andthe pathologic grading of hepatic fibrosisshowed that there was no significant differencebetween the treatment group and the modelgroup (P>0.05).CONCLUSION The experimental rat model ofhepatic fibrosis is one of the preferable modelsto estimate the curative effect of anti-hepaticfibrosis drugs. The asON phosphorthioate ofTIMP-1 could block the gene and proteinexpression of TIMP-1 in the liver of experimentalhepatic fibrosis rats at the mRNA level. It ispossible to reverse hepatic fibrosis, and it isexpected to study a new drug of anti-hepaticfibrosis on the genetic level. Colchicine has verylimited therapeutic effect on hepatic fibrosis,furthermore, its toxicity and side effects areobvious. | Qing He Nie Yong Qian Cheng Yu Mei Xie Yong Xing Zhou Yi Zhan Cao The Center of Infectious Disease Diagnosis and Treatment of PLA,Tangdu Hospital,Forth Military Medical University,Xi’an 710038,Shaanxi Province,ChinaDr,Qing He Nie graduated from Qinghai Medical College as a doctor in 1983,got master degree at Beijing 302 Army Hospital in 1993,got doctor degree at the Third Military Medical University in 1998,engaged in postdoctoral research at the Fourth Military Medical University from 1998 to 2000,now an associate professor,specialized in clinical and experimental research of infectious diseases,had more than 90 papers published,coauthor of ten books,first author of one book. | 2001 | World Journal of Gastroenterology2001，7，3： | 73 |

| 5 | Early Serum HBsAg Kinetics as Predictor of HBsAg Loss in Patients with HBeAg-Negative Chronic Hepatitis B after Treatment with Pegylated Interferonα-2a显示文摘Hepatitis B surface antigen(HBsAg)loss is an ideal treatment endpoint for patients with chronic hepatitis B(CHB).We investigated the predictive value of on-treatment HBsAg levels for HBsAg loss in hepatitis B e antigen(HBe Ag)-negative CHB patients who received 120-week PEG-IFNα-2a treatment.Serum HBV DNA,HBsAg,and anti-HBs levels were assayed at baseline and every 3 months during the treatment.Of 81 patients,12 achieved HBsAg loss,20 achieved HBsAg\100 IU/mL,and 49 maintained HBs Ag C 100 IU/mL.HBsAg loss rate was only 3.7%at 48 weeks,while it reached to 11.1%and 14.8%after treatment of 96 weeks and 120 weeks.The cutoff HBs Ag levels at 12 weeks predicting HBsAg loss at 96 weeks and 120 weeks of treatment were 400 IU/mL and 750 IU/mL,with AUC 0.725 and 0.722,positive predictive value(PPV)29.41%and 30.56%,and negative predictive value(NPV)93.75%and 97.78%,respectively.The cutoff HBsAg levels at 24 weeks predicting HBsAg loss at 96 weeks and 120 weeks of treatment were 174 IU/m L and 236 IU/mL respectively,with AUC 0.925 and 0.922,PPV 40.0%and 46.15%,and both NPV 100%.The predictive ability of the cutoff HBsAg levels at 24 weeks was better than that at 12 weeks for HBs Ag loss at either 96 or 120 weeks(χ~2=3.880,P=0.049 andχ~2=4.412,P=0.036).These results indicate that extended therapy is critical to HBsAg loss in HBe Ag-negative CHB patients during PEG-IFN treatment,and the HBsAg level at 24 weeks can be used to predict HBsAg loss during tailoring PEG-IFN therapy. | Minghui Li Lu Zhang Yao Lu Qiqi Chen Huihui Lu Fangfang Sun Zhan Zeng Gang Wan Linqing Zhao Yao Xie | 2021 | Virologica Sinica2021，36，2： | 15 |
| 6 | Comprehensive treatments for hepatocellular carcinoma with tumor thrombus in major portal vein显示文摘AIM: To evaluate the efficacy of transcatheter arterial chemoembolisation(TACE) compared with surgical intervention and sorafenib for treatment of hepatocellular carcinoma(HCC) in patients with tumor thrombus extending to the main portal vein.METHODS: From 2009 to 2013, a total of 418 HCC patients with tumor thrombus extending to the main portal vein were enrolled in this study and divided into four groups. These groups underwent different treatments as follows: TACE(n = 307), surgical intervention(n = 54), sorafenib(n = 15) and palliativetreatment(n = 42). Overall survival rates were determined by Kaplan-Meier method, and differences between the groups were identified through log-rank analysis. Cox's proportional hazard model was used to identify the risk factors for survival.RESULTS: The mean survival periods for patients in the TACE, surgical intervention, sorafenib and palliative treatment groups were 10.39, 4.13, 5.54 and 2.82 mo, respectively. For the TACE group, the 3-, 6-, 12-and 24-mo survival rates were 94.1%, 85.9%, 51.5% and 0.0%, respectively. The corresponding rates were 60.3%, 22.2%, 0.0% and 0.0% for the surgical intervention group and 50.9%, 29.5%, 0.0% and 0.0% for the sorafenib group. Evidently, the results in the TACE group were significantly higher than those in the other groups(P < 0.0001). Furthermore, no significant difference among survival rates was observed between TACE with/without sorafenib(10.22 mo vs 10.52 mo, P = 0.615). No significant difference in survival rates was also found among the surgical intervention, sorafenib and palliative treatment groups(P > 0.05). These values significantly increased after TACE with/without sorafenib compared with other treatments(P < 0.05).CONCLUSION: For HCC patients with tumor thrombus extending to the main portal vein, TACE can yield a higher survival rate than surgical intervention or sorafenib treatment. | Hai-Hong Ye Jia-Zhou Ye Zhi-Bo Xie Yu-Chong Peng Jie Chen Liang Ma Tao Bai Jun-Ze Chen Zhan Lu Hong-Gui Qin Bang-De Xiang Le-Qun Li | 2016 | World Journal of Gastroenterology2016，22，13： | 14 |
| 7 | Hangzhou criteria as downstaging criteria in hepatocellular ca显示文摘Background:The downstaging of hepatocellular carcinoma(HCC)has been confirmed to benefit liver transplantation(LT)patients whose tumors are beyond the transplantation criteria.Milan criteria(MC),a tumor size and number-based assessment,is currently used as the endpoint in these patients.However,many studies believe that tumor biological behavior should be added to the evaluation criteria for downstaging efficacy.Hence,this study aimed to explore the feasibility of Hangzhou criteria(HC),which introduced tumor grading and alpha-fetoprotein in addition to tumor size and number,as an endpoint of downstaging.Methods:We performed a multicenter and retrospective study of 206 patients accepted locoregional therapy(LRT)as downstaging/bridge treatment prior to LT in three centers of China.Results:Recipients were divided into four groups:failed downstaging to the HC(group A,n=46),successful downstaging to the HC(group B,n=30),remained within the HC all the time(group C,n=113),and tumor progressed(group D,n=17).The 3-year HCC recurrence probabilities of groups B and C were not significantly different(10.3%vs.11.6%,P=0.87).The HCC recurrent rate was significantly higher in group A(52.3%)compared with that in group B/C(P<0.05).Seven patients(7/76,9.2%)whose tumor exceeded the the HC were successfully downstaged to the MC,and 39.5%(30/76)to the the HC.In group B,23 patients remained beyond the MC and their survivals were as well as those of patients within the MC.Conclusions:Compared to the MC,HC downstaging criteria can give more HCC patients access to LT and furthermore,the outcome of these patients is the same as those matching MC downstaging criteria.Hangzhou downstaging criteria therefore is applicable in clinical practice. | Qi-Fan Zhan Sun-Bin Ling Yi-Nan Deng Qiao-Nan Shan Qian-Wei Ye Sheng-Jun Xu Guang-Jiang Jiang Di Lu Xu-Yong Wei Li Zhuang Wu Zhang Tian Shen Bei-Ni Cen Hai-Yang Xie Ji-Min Liu Jian Wu Shu-Sen Zheng Yang Yang Xiao Xu | 2020 | Hepatobiliary & Pancreatic Diseases International2020，19，4： | 11 |

| 9 | Temperature effect on aerobic denitrification and nitrification显示文摘Nitrogen loss without organic removal in biofilter was observed and its possible reason was explained. A lower hydraulic loading could improve aerobic denitrification rate. Aerobic denitrification was seriously affected by low temperature(below 10℃). However, nitrification rate remained high when the temperature dropped from 15℃ to 5℃. It seemed the autotrophic biofilm in BAF could alleviate the adverse effect of low temperature. | XIE Shu guang *, ZHANG Xiao jian, WANG Zhan sheng (Department of Environmental Science and Technology, Tsinghua University, Beijing 100084, China. ) | 2003 | Journal of Environmental Sciences2003，15，5： | 11 |

| 11 | E2F-1 overexpression inhibits human gastric cancer MGC-803 cell growth in vivo显示文摘AIM: To evaluate the influence of E2F-1 on the growth of human gastric cancer(GC) cells in vivo and the mechanism involved. METHODS: E2F-1 recombinant lentiviral vectors were injected into xenograft tumors of MGC-803 cells in nude mice, and then tumor growth was investigated. Overexpression of transcription factor E2F-1 was assessed by reverse transcription-polymerase chain reaction(RT-PCR) and Western blotting analysis. Apoptosis rates were determined using a terminal deoxynucleotidyl transferase-mediated d UTP-biotin nick end labeling(TUNEL) assay. Expression levels of certain cell cycle regulators and apoptosis-related proteins, such as Bax, survivin, Bcl-2, cyclin D1, S-phase kinaseassociated protein 2, and c-Myc were examined by Western blotting and RT-PCR. RESULTS: Xenograft tumors of MGC-803 cells in nude mice injected with E2F-1 recombinant lentiviral vectors stably overexpressed the E2F-1 gene as measured by semi-quantitative RT-PCR(relative m RNA expression: 0.10 ± 0.02 vs 0.05 ± 0.02 for control vector and 0.06 ± 0.03 for no infection; both P < 0.01) and Western blotting(relative protein expression: 1.90 ± 0.05 vs 1.10 ± 0.03 in control vector infected and 1.11 ± 0.02 for no infection; both P < 0.01). The growth-curve of tumor volumes revealed that infection with E2F-1 recombinant lentiviral vectors significantly inhibited the growth of human GC xenografts(2.81 ± 1.02 vs 6.18 ± 1.15 in control vector infected and 5.87 ± 1.23 with no infection; both P < 0.05) at 15 d after treatment. TUNEL analysis demonstrated that E2F-1 overexpression promoted tumor cell apoptosis(18.6% ± 2.3% vs 6.7% ± 1.2% in control vector infected 6.3% ± 1.2% for no infection; both P < 0.05). Furthermore, lentiviral vector-mediated E2F-1 overexpression increased theexpression of Bax and suppressed survivin, Bcl-2, cyclin D1, Skp2, and c-Myc expression in tumor tissue.CONCLUSION: E2F-1 inhibits growth of GC cells via regulating multiple signaling pathways, and may play an important role in targeted therapy for GC. | Wei-Yuan Wei Lin-Hai Yan Xiao-Tong Wang Lei Li Wen-Long Cao Xiao-Shi Zhang Ze-Xu Zhan Han Yu Yu-Bo Xie Qiang Xiao | 2015 | World Journal of Gastroenterology2015，21，2： | 10 |

| 14 | Comparison of ground truth location of earthquake from InSAR and from ambient seismic noise: A case study of the 1998 Zhangbei earthquake显示文摘Because ambient seismic noise provides estimated Green's function (EGF) between two sites with high accuracy, Rayleigh wave propagation along the path connecting the two sites is well resolved. Therefore, earthquakes which are close to one seismic station can be well located with calibration extracting from EGF. We test two algorithms in locating the 1998 Zhangbei earthquake, one algorithm is waveform-based, and the other is traveltime-based. We first compute EGF between station ZHB (a station about 40 km away from the epicenter) and five IC/IRIS stations. With the waveform-based approach, we calculate 1D synthetic single-force Green's functions between ZHB and other four stations, and obtain traveltime corrections by correlating synthetic Green's functions with EGFs in period band of 10-30 s. Then we locate the earthquake by minimizing the differential travel times between observed earthquake waveform and the 1D synthetic earthquake waveforms computed with focal mechanism provided by Global CMT after traveltime correction from EGFs. This waveform-based approach yields a location which error is about 13 km away from the location observed with InSAR. With the traveltime-based approach, we begin with measuring group velocity from EGFs as well as group arrival time on observed earthquake waveforms, and then locate the earthquake by minimizing the difference between observed group arrival time and arrival time measured on EGFs. This traveltime-based approach yields accuracy of 3 km, Therefore it is feasible to achieve GT5 (ground truth location with accuracy 5 km) with ambient seismic noises. The less accuracy of the waveform-based approach was mainly caused by uncertainty of focal mechanism. | Jun Xie Xiangfang Zeng Weiwen Chen Zhongwen Zhan | 2011 | Earthquake Science2011，24，2： | 7 |

| 17 | Silencing MYH9 blocks HBx-induced GSK3βubiquitination and degradation to inhibit tumor stemness in hepatocellular carcinoma显示文摘MYH9 has dual functions in tumors.However,its role in inducing tumor stemness in hepatocellular carcinoma(HCC)is not yet determined.Here,we found that MYH9 is an effective promoter of tumor stemness that facilitates hepatocellular carcinoma pathogenesis.Importantly,targeting MYH9 remarkably improved the survival of hepatocellular carcinoma-bearing mice and promoted sorafenib sensitivity of hepatocellular carcinoma cells in vivo.Mechanistic analysis suggested that MYH9 interacted with GSK3βand reduced its protein expression by ubiquitin-mediated degradation,which therefore dysregulated theβ-catenin destruction complex and induced the downstream tumor stemness phenotype,epithelial–mesenchymal transition,and c-Jun signaling in HCC.C-Jun transcriptionally stimulated MYH9 expression and formed an MYH9/GSK3β/β-catenin/c-Jun feedback loop.X protein is a hepatitis B virus(HBV)-encoded key oncogenic protein that promotes HCC pathogenesis.Interestingly,we observed that HBV X protein(HBX)interacted with MYH9 and induced its expression by modulating GSK3β/β-catenin/c-Jun signaling.Targeting MYH9 blocked HBX-induced GSK3βubiquitination to activate theβ-catenin destruction complex and suppressed cancer stemness and EMT.Based on TCGA database analysis,MYH9 was found to be elevated and conferred poor prognosis for hepatocellular carcinoma patients.In clinical samples,high MYH9 expression levels predicted poor prognosis of hepatocellular carcinoma patients.These findings identify the suppression of MYH9 as an alternative approach for the effective eradication of CSC properties to inhibit cancer migration,invasion,growth,and sorafenib resistance in HCC patients.Our study demonstrated that MYH9 is a crucial therapeutic target in HCC. | Xian Lin Ai-min Li Yong-Hao Li Rong-Cheng Luo Yu-Jiao Zou Yi-Yi Liu Chen Liu Ying-Ying Xie Shi Zuo Zhan Liu Zhen Liu Wei-Yi Fang | 2020 | Signal Transduction and Targeted Therapy2020，5，1： | 6 |
| 18 | Problems, challenges and future of plant disease management: from an ecological point of view显示文摘Plant disease management faces ever-growing challenges due to:(i)increasing demands for total,safe and diverse foods to support the booming global population and its improving living standards;(ii)reducing production potential in agriculture due to competition for land in fertile areas and exhaustion of marginal arable lands;(iii)deteriorating ecology of agro-ecosystems and depletion of natural resources;and(iv)increased risk of disease epidemics resulting from agricultural intensification and monocultures.Future plant disease management should aim to strengthen food security for a stable society while simultaneously safeguarding the health of associated ecosystems and reducing dependency on natural resources.To achieve these multiple functionalities,sustainable plant disease management should place emphases on rational adaptation of resistance,avoidance,elimination and remediation strategies individually and collectively,guided by traits of specific host-pathogen associations using evolutionary ecology principles to create environmental(biotic and abiotic)conditions favorable for host growth and development while adverse to pathogen reproduction and evolution. | HE Dun-chun ZHAN Jia-sui XIE Lian-hui | 2016 | Journal of Integrative Agriculture2016，15，4： | 6 |
| 19 | Aescin-induced reactive oxygen species play a pro-survival role in human cancer cells via ATM/AMPK/ULK1-mediated autophagy显示文摘Aescin, a natural mixture of triterpene saponins, has been reported to exert anticancer effect. Recent studies show that aescin increases intracellular reactive oxygen species (ROS) levels. However, whether the increased ROS play a role in the anticancer action of aescin remains to be explored. In this study, we demonstrated that aescin (20-80 μg/mL) dose-dependently induced apoptosis and activated mammalian target of rapamycin (mTOR)-independent autophagy in human hepatocellular carcinoma HepG2 cells and colon carcinoma HCT 116 cells. The activation of autophagy favored cancer cell survival in response to aescin, as suppression of autophagy with ATG5 siRNAs or 3-methyladenine (3-MA), a selective inhibitor of autophagy, promoted aescin-induced apoptosis in vitro, and significantly enhanced the anticancer effect of aescin in vivo. Meanwhile, aescin dose-dependently elevated intracellular ROS levels and activated Ataxia-telangiectasia mutated kinase/AMP-activated protein kinase/UNC-51-like kinase-1 (ATM/AMPK/ULK1) pathway. The ROS and ATM/AMPK/ULK1 pathway were upstream modulators of the aescin-induced autophagy, as N-acetyl-L-cysteine (NAC) or ATM kinase inhibitor (KU-55933) remarkably suppressed aescin-induced autophagy and consequently promoted aescin-induced apoptosis, whereas overexpression of ATG5 partly attenuated NAC-induced enhancement in aescin-induced apoptosis. In conclusion, this study provides new insights into the roles of aescin-mediated oxidative stress and autophagy in cancer cell survival. Our results suggest that combined administration of the antioxidants or autophagic inhibitors with aescin might be a potential strategy to enhance the anticancer effect of aescin. | Bin Li Guo-liang Wu Wei Dai Gang Wang Hao-yuan Su Xue-ping Shen Rui Zhan Jia-ming Xie Zhong Wang Zheng-hong Qin Quan-gen Gao Gen-hai Shen | 2018 | Acta Pharmacologica Sinica2018，39，12： | 5 |
| 20 | Early Permian Sunidyouqi suprasubduction-zone ophiolites in the central Solonker suture zone(Inner Mongolia, China)显示文摘Different final closing ages have been proposed for the evolution of the Paleo-Asian Ocean(PAO),including Late Silurian, pre-Late Devonian, Early Permian, Late-Permian and Late Permian-Early Triassic.Ophiolites represent fragments of ancient oceanic crust and play an important role in identifying the suture zone and unveiling the evolutionary history of fossil oceans. Our detailed geological, geochemical and geochronological investigations argue for the existence of Early Permian(297 Ma) SSZ type ophiolites in the Sunidyouqi area of central Inner Mongolia, China. The gabbros and basalts show LREE depleted REE patterns and left-leaning primitive mantle-normalized spider diagrams with variable negative Nb-Ta anomalies(Nb~*= 0.24-1.28 and 0.29-0.55, respectively). The Sunidyouqi ophiolites were generated in a mature back-arc basin. The Sunidyouqi ophiolites share the same petrological,geochemical and geochronological characteristics with the other ophiolites along the Solonker suture zone, delineating a Late Paleozoic ocean and arc-trench system. This Late Paleozoic ocean and arc-trench system coincides with a Permian paleobiogeographical boundary, i.e. the boundary between the northern cold climate(Boreal faunal-Angaraland floral realm), and a southern warm climate(Tethys faunal-Cathaysian floral realm). A tectonic scenario was proposed at last for the closure of the SE PAO involving(1) Late Ordovician to Middle Permian continuous southward subduction beneath the northern margin of North China;(2) Carboniferous to Middle Permian continuous northward subduction the forming the Northern Accretionary Orogen;(3) Late Permian final closure of the SE PAO. | Guo Xu Huichuan Liu Yinglei Li Zhan Xu Yan Xie | 2019 | Geoscience Frontiers2019，10，3： | 5 |
