| 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 |
| 3 | Spatio-temporal rupture process of the 2008 great Wenchuan earthquake显示文摘Focal mechanism and dynamic rupture process of the Wenchaun Ms8.0 earthquake in Sichuan province on 12 May 2008 were obtained by inverting long period seismic data from the Global Seismic Network (GSN), and characteristics of the co-seismic displacement field near the fault were quantitatively ana-lyzed based on the inverted results to investigate the mechanism causing disaster. A finite fault model with given focal mechanism and vertical components of the long period P-waves from 21 stations with evenly azimuthal coverage were adopted in the inversion. From the inverted results as well as after-shock distribution, the causative fault of the great Wenchuan earthquake was confirmed to be a fault of strike 225°/dip 39°/rake 120°, indicating that the earthquake was mainly a thrust event with right-lateral strike-slip component. The released scalar seismic moment was estimated to be about 9.4×1020―2.0×1021 Nm, yielding moment magnitude of Mw7.9―8.1. The great Wenchuan earthquake occurred on a fault more than 300 km long, and had a complicated rupture process of about 90 s duration time. The slip distribution was highly inhomogeneous with the average slip of about 2.4 m. Four slip-patches broke the ground surface. Two of them were underneath the regions of Wenchuan-Yingxiu and Beichuan, respectively, with the first being around the hypocenter (rupture initiation point), where the largest slip was about 7.3 m, and the second being underneath Beichuan and extending to Pingwu, where the largest slip was about 5.6 m. The other two slip-patches had smaller sizes, one having the maximum slip of 1.8 m and lying underneath the north of Kangding, and the other having the maximum slip of 0.7 m and lying underneath the northeast of Qingchuan. Average and maximum stress drops over the whole fault plane were estimated to be 18 MPa and 53 MPa, respectively. In addition, the co-seismic displacement field near the fault was analyzed. The results indicate that the features of the co-seismic displacement field were coincident with those of the intensity distribution in the meizo-seismal area, implying that the large-scale, large-amplitude and surface-broken thrust dislocation should be responsible for the serious disaster in the near fault area. | ZHANG Yong FENG WanPeng XU LiSheng ZHOU ChengHu CHEN YunTai | 2009 | Science China Earth Sciences2009,52,2: | 68 |
| 4 | Standard triple therapy for Helicobacter pylori infection in China: A meta-analysis显示文摘AIM:To assess the efficacy and safety of standard triple therapy compared with other pre-existing and new therapies in China.METHODS:Literature searches were conducted in the following databases:PubMed,EMBASE,the Cochrane Central Register of Controlled Trials,the VIP database,the China National Knowledge Infrastructure database,and the Chinese Biomedical Database.A meta-analysis of all randomized controlled trials(RCTs)comparing standard triple therapy for the eradication of Helicobacter pylori with pre-existing and new therapies in China was performed using Comprehensive Meta-Analysis 2.0.There were 49 studies that met our criteria and the qualities of these studies were assessed using the Jadad scale.The Mantel-Haenszel method was used for pooling dichotomous data.We also conducted subgroupanalyses according to age,duration of treatment and drug type.Sensitivity analyses and a cumulative metaanalysis were also performed with CMA 2.0.Publication bias was evaluated using Egger’s test,Begg’s test or a funnel plot.RESULTS:A total of 49 RCTs including 8332 patients were assessed.This meta-analysis showed that standard triple therapy with proton pump inhibitors(PPIs),amoxicillin(AMO)and clarithromycin(CLA)was inferior to sequential therapy[relative risk(RR)=0.863;95%confidence interval(CI):0.824-0.904],but was not superior to quadruple therapy(RR=1.073;95%CI:0.849-1.357)or other triple therapies(RR=1.01;95%CI:0.936-1.089).The meta-analysis also suggested that standard triple therapy is slightly more effective than dual therapy(RR=1.14;95%CI:0.99-1.31).However,the differences were not statistically significant.We removed the only trial with a regimen lasting14 d by sensitivity analysis and found that 7-d standard triple therapy was superior to 7-d dual therapy(RR=1.222;95%CI:1.021-1.461).Moreover,a sub-analysis based on the duration of quadruple therapy indicated that the 7-d and 10-d standard triple therapies were inferior to sequential therapy(RR=0.790;95%CI:0.718-0.868;RR=0.917;95%CI:0.839-1.002,respectively).Additionally,there were no significant differences in cure rate or adverse events among standard triple therapy,quadruple therapy,and other triple therapies(RR=0.940;95%CI:0.825-1.072;RR=1.081;95%CI:0.848-1.378,respectively).Standard triple therapy had a higher occurrence of side effects than sequential therapy(RR=1.283;95%CI:1.066-1.544).CONCLUSION:The eradication rates with a standard triple therapy consisting of PPI,AMO,and CLA are suboptimal in China,and new treatment agents need to be developed. | Ben Wang Zhi-Fa Lv You-Hua Wang Hui Wang Xiao-Qun Liu Yong Xie Xiao-Jiang Zhou | 2014 | World Journal of Gastroenterology2014,20,40: | 46 |

| 7 | Active Tectonics and Erosional Unloading at the Eastern Margin of the Tibetan Plateau显示文摘The eastern margin of the Tibetan Plateau is marked by an extremely steep mountain front with relief of over 5 km. This topography,coupled with abundant Mesozoic thrusts within the margin,explains why tectonic maps of the India-Asia collision typically show the eastern margin as a major thrust zone. Actually,it does not like that. Field observations suggest that the margin is better characterized as a zone of NNE-directed dextral shear with extensive strike-slip faulting and secondary thrusting. The high relief and steep gradients are partially explained by erosional unloading of an elastic lithosphere;the pre-erosion inherited topography may be the inherited Mesozoic thrust belt landscape modified by a component of Cenozoic tectonic shortening. | Alexander L.

| 8 | Dissection of genetic overlap of salt tolerance QTLs at the seedling and tillering stages using backcross introgression lines in rice显示文摘QTLs for salt-tolerance(ST)related traits at the seedling and tillering stages were identified using 99 BC2F8 introgression lines(IL)derived from a cross between IR64(indica)as a recurrent parent and Binam(japonica)from Iran as the donor parent.Thirteen QTLs affecting survival days of seedlings(SDS), score of salt toxicity of leaves(SST),shoot K + concentration(SKC)and shoot Na + concentration(SNC) at the seedling stage and 22 QTLs underlying fresh weight of shoots(FW),tiller number per plant(TN) and plant height(PH)at the tillering stage were identified.Most QTLs detected at the tillering stage showed obvious differential expression to salt stress and were classified into three types based on their differential behaviors.Type I included 11 QTLs which were expressed only under the non-stress condition.Type II included five QTLs expressed in the control and the salt stress conditions,and three of them(QPh5,QPh8 and QTn9)had similar quantity and the same direction of gene effect,suggesting their expression was less influenced by salt stress.Type III included six QTLs which were detectable only under salt stress,suggesting that these QTLs were apparently induced by the stress.Thirteen QTLs affecting trait difference or trait stability of ILs between the stress and non-stress conditions were identified and the Binam alleles at all loci except QPh4,QTn2 and QFw2a decreased trait difference.The three QTLs less influenced by the stress and 13 QTLs affecting trait stability were considered as ST QTLs which contributed to ST.Comparing the distribution of QTLs detected at the seedling and tillering stages,most(69%)of them were genetically independent.Only four were the same or adjacent regions on chromosomes 1,2,8 and 11 harboring ST QTLs detected at the two stages,suggesting that partial genetic overlap of ST across the two stages occurs.It is likely,therefore,to develop ST rice variety for both stages by pyramiding of ST QTLs of different stages or selection against the overlapping QTLs between the two stages via marker-assisted selection(MAS). | ZANG JinPing 1 ,SUN Yong 1 ,WANG Yun 1 ,YANG Jing 1 ,LI Fang 1 ,ZHOU YongLi 1 ,ZHU LingHua 1 , Reys JESSICA2,Fotokian MOHAMMADHOSEIN 2,XU JianLong 1&LI ZhiKang 1,2 1Institute of Crop Sciences/National Key Facility for Crop Gene Resources&Genetic Improvement,Chinese Academy of Agricul- tural Sciences,Beijing 100081,China 2International Rice Research Institute,DAPO Box 7777,Metro Manila,Philippines | 2008 | Science China(Life Sciences)2008,51,7: | 32 |
| 9 | Artesunate synergizes with sorafenib to induce ferroptosis in hepatocellular carcinoma显示文摘Sorafenib is the first-line medication for advanced hepatocellular carcinoma(HCC),but it can only extend limited survival.It is imperative to find a combination strategy to increase sorafenib efficacy.Artesunate is such a preferred candidate,because artesunate is clinically well-tolerated and more importantly both drugs can induce ferroptosis through different mechanisms.In this study we investigated the combined effect of sorafenib and artesunate in inducing ferroptosis of HCC and elucidated the involved molecular mechanisms.We showed that artesunate greatly enhanced the anticancer effects of low dose of sorafenib against Huh7,SNU-449,and SNU-182 HCC cell lines in vitro and against Huh7 cell xenograft model in Balb/c nude mice.The combination index method confirmed that the combined effect of sorafenib and artesunate was synergistic.Compared with the treatment with artesunate or sorafenib alone,combined treatment induced significantly exacerbated lipid peroxidation and ferroptosis,which was blocked by N-acetyl cysteine and ferroptosis inhibitors liproxstatin-1 and deferoxamine mesylate,but not by inhibitors of other types of cell death(z-VAD,necrostatin-1 and belnacasan).In Huh7 cells,we demonstrated that the combined treatment induced oxidative stress and lysosome-mediated ferritinophagy,two essential aspects of ferroptosis.Sorafenib at low dose mainly caused oxidative stress through mitochondrial impairments and SLC7A11-invovled glutathione depletion.Artesunate-induced lysosome activation synergized with sorafenib-mediated pro-oxidative effects by promoting sequential reactions including lysosomal cathepsin B/L activation,ferritin degradation,lipid peroxidation,and consequent ferroptosis.Taken together,artesunate could be repurposed to sensitize sorafenib in HCC treatment.The combined treatment can be easily translated into clinical applications. | Zhong-jie Li Hui-qi Dai Xiao-wei Huang Ji Feng Jing-huan Deng Zi-xuan Wang Xiao-mei Yang Yu-jia Liu Yong Wu Pan-hong Chen Huan Shi Ji-gang Wang Jing Zhou Guo-dong Lu | 2021 | Acta Pharmacologica Sinica2021,42,2: | 31 |

| 12 | Different histological subtypes of parotid gland tumors: CT findings and diagnostic strategy显示文摘AIM:To present computed tomography(CT) findings of different histological subtypes of parotid gland masses in detail and to establish diagnostic strategy.METHODS:From January 2009 to November 2011,56 patients were collected through the histopathology and Picture Archiving and Communication Systems records,which revealed 5 basal cell adenoma(BCA),16 pleomorphic adenoma(PA),25 Warthin's tumor(War-T),3 Kimura's disease(KD) and 7 parotid carcinoma(PCa) cases.All the CT images were retrospectively analyzed by two radiologists in consensus,based on their description of morphology(location,number,size,margin and fibrous capsule) and enhancement patterns of masses.In addition,the diagnostic efficiency of diagnostic strategy is tested.RESULTS:War-T and BCA patients' mean age was 59.9 ± 12.6 years and 58.4 ± 18.2 years;the significant difference was seen in War-T vs PA and BCA vs PA.About 40% of War-Ts presented with bilateral multifocal lesions,a higher ratio than others.Seventy two percent of War-Ts were limited to the superficial lobe,followed by BCA 60% and PA 40%.Vessel facing sign and enlarged lymph nodes were both frequent in War-T,which respectively accounts for 84% and 76% of cases.Rapid contrast enhancement and decreases were unique for War-T.BCA and PA showed obvious delayed enhancement.The diagnostic strategy of parotid gland tumor had a good diagnostic efficiency,with high accuracy,sensitivity and specificity.CONCLUSION:Determination of the histological subtypes of parotid gland masses might be possible based on CT findings and clinical data.A diagnostic strategy with high diagnostic efficiency was established. | Zhi-Feng Xu Fang Yong Tian Yu Ying-Yu Chen Qiang Gao Tao Zhou Ai-Zhen Pan Ren-Hua Wu | 2013 | World Journal of Radiology2013,5,8: | 25 |
| 13 | Impact of hypoxic preconditioning on apoptosis and its possible mechanism in orthotopic liver autotransplantation in rats显示文摘BACKGROUND:Hepatocyte apoptosis is a severe form of cell death after hepatic ischemia-reperfusion injury(HIRI), and its relief is an important issue in liver transplantation. Hypoxic preconditioning(HP)is considered to have protective effects on HIRI.This study was designed to explore the impact of HP on apoptosis and its possible mechanism during orthotopic liver autotransplantation. METHODS:A modified orthotopic liver autotransplantation model was used to simulate HIRI.Sprague-Dawley rats were randomly divided into normal control,autotransplantation (AT)and HP groups.The HP group was subjected to an 8%oxygen atmosphere for 90 minutes before surgery.At 1,6 and 24 hours after surgery,the rats were killed and their liver tissue was sampled to assess the expression of Bcl-2 protein.The samples were subjected to blood chemistry study,morphological study under a light or transmission electron microscope,and quantitative study of mitochondria. RESULTS:The serum levels of ALT and AST in the HP group were lower than those in the AT group at 1,6 and 24 hours after orthotopic liver autotransplantation(P<0.05).Bcl-2 protein expression was increased in the HP group at each measurement point(P<0.05).Light microscopy showed that hepatic injury in the AT group was much more severe than in the HP group.Hepatocytes in the AT group showed typical apoptosis signs under a transmission electron microscope.The ultrastructural appearance of hepatocytes in the HP group was much better than in the AT group,and the area,perimeter and diameter of the mitochondria were smaller in the HP group than in the AT group(P<0.05). CONCLUSIONS:Hepatocytes sense and respond to decreased tissue oxygenation.Stimulation by HP relieves apoptosis by upregulating expression of Bcl-2 protein and its protection of mitochondria after orthotopic liver autotransplantation. | Jin, Cheng Zhang, Pei-Jian Wu, Xiao-Min Zhou, Bin Li, Yong Liu, Xin-Yan Feng, Min Tao, Li-De | 2009 | Hepatobiliary & Pancreatic Diseases International2009,8,1: | 26 |
| 14 | Three-dimensional finite element analysis of weakened roots restored with different cements in combination with titanium alloy posts显示文摘Background It is very difficult and relatively unpredictable to preserve and restore severely weakened pulpless roots. To provide much needed benefit basis for clinical practice, this study was carried out to analyze the stress distribution in weakened roots restored with different cements in combination with titanium alloy posts. Finite element analysis (FEA) was employed in the study. Methods A pseudo three-dimensional model of a maxillary central incisor with flared root canal, theoretically restored with titanium alloy posts in combination with different cements, was established. The analysis was performed by use of ANSYS software. The tooth was assumed to be isotropic, homogenous and elastic. A load of 100 N at an angle of 45°to the longitudinal axis was applied at the palatal surface of the crown. The distributions of stresses in weakened roots filled with cements of different elastic modulus were analyzed by the three-dimensional FEA model. Results Several stress trends were observed when the stress cloud atlas obtained in the study was analyzed. With the increase of the elastic modulus of cements from 1.8 GPa to 22.4 GPa, the stress values in dentin decreased from 39.58 MPa to 31.43 MPa and from 24.51 MPa to 20.76 MPa (respectively, for maximum principle stress values and Von Mises stress values). When Panavia F and zinc phosphate cement were used, the stress peak values in dentin were very small with no significant difference observed, and the Von Mises stress values were 20.87 MPa and 20.76 MPa respectively. On the other hand, maximum principle stress value and Von Mises stress value in cement layer increased with the increase of the elastic modulus of cements. Conclusions The result of this study demonstrated that elastic modulus was indeed one of the important parameters to evaluate property of the cements. Our three-dimensional FEA model study also found that the cement with elastic modulus similar to that of dentin could reinforce weakened root and reduce the stress in dentin. Thus, it may be a better choice for the restoration of weakened roots in clinical practice. | LI Li-li WANG Zhong-yi BAI Zhong-cheng MAO Yong GAO Bo XIN Hai-tao ZHOU Bing ZHANG Yong LIU Bing | 2006 | Chinese Medical Journal2006,,4: | 26 |

| 16 | Furazolidone-based triple and quadruple eradication therapy for Helicobacter pylori infection显示文摘AIM: To evaluate the efficacy of furazolidone-based triple and quadruple therapy in eradicating Helicobacter pylori(H. pylori) in a multi-center randomized controlled trial.METHODS: A total of 720 H. pylori positive patients with duodenal ulcer disease were enrolled at 10 different hospitals in Jiangxi province in China. The patients were randomly assigned to four treatment groups as follows: patients in Groups 1 and 3 received rabeprazole(10 mg), amoxicillin(1000 mg) and furazolidone(100 mg) twice daily for 7 and 10 d, respectively; patients in Groups 2 and 4 received rabeprazole(10 mg), bismuth(220 mg), amoxicillin(1000 mg) and furazolidone(100 mg) twice daily for 7 and 10 d, respectively. The primary outcome measure was H. pylori eradication rate 4 wk after treatment by intention-to-treat and per protocol analysis, while the secondary outcome measures were symptom and sign changes at the end of treatment and 4 wk after the end of treatment, as well as the proportion of patients who developed adverse events.RESULTS: The demographic data of the four groups were not significantly different. Overall, 666 patients completed the scheme and were re-assessed with the 13C-urea breath test. The intention-to-treat analysis of the H. pylori eradication rates in Groups 1, 2, 3 and 4 were 74.44%, 82.78%, 78.89% and 86.11%, respectively. The H. pylori eradication rate in Group 4 was significantly higher than that in Group 1. According tothe per protocol analysis, the H. pylori eradication rates in Groups 1, 2, 3 and 4 were 81.21%, 89.22%, 85.54% and 92.26%, respectively. The H. pylori eradication rate in Group 4 was significantly higher than that in Group 1.
