6Stress changes on major faults caused by 2013 Lushan earthquake and its relationship with 2008 Wenchuan earthquake显示文摘On April 20, 2013, an Ms7.0 earthquake occurred in Ya'an-Lushan region, Sichuan Province, China, killing and injuring morethan one thousand people. Therefore, it is critical to outline the areas with potential aftershocks before reconstruction andre-settlement as to avoid future disasters. Based on the elastic dislocation theory and multi-layered lithospheric model, we calculate the co-and post-seismic stress changes caused by the Wenchuan and Lushan earthquakes to discuss the relationshipbetween Mw7.9 Wenchuan earthquake and Ms7.0 Lushan earthquake, the influences on the distribution of aftershock caused bythe Lushan earthquake, and the stress changes on major faults in this region. It is shown that the Coulomb failure stress increment on the hypocenter of Lushan earthquake caused by the Wenchuan earthquake is about 0.0037-0.0113 MPa. And the possible maximum value (0.0113 MPa) is larger than the threshold of stress triggering. Therefore, the occurrence of Lushanearthquake is probably effectively promoted by the Wenchuan earthquake. The aftershock distribution is well explained by theco-seismic stress changes of Lushan earthquake. By the two ends of the rupture of Lushan earthquake with increased Coulombfailure stress, a lack of aftershock recordings indicates the high seismic hazard. The stress accumulation and correspondingseismic hazard on the Kangding-Dafu segment of the Xinshuihe fault, the Beichuan-Yingxiu fault, the Pengxian-Guanxianfault, and the Ya'an fault are further increased by the Lushan earthquake and post-seismic process of Wenchuan earthquake.SHAN Bin XIONG Xiong ZHENG Yong JIN BiKai LIU ChengLi XIE ZhuJun HSU HouTze 2013Science China Earth Sciences2013,56,7:49
7Crustal and upper mantle structure and the deep seismogenic environment in the source regions of the Lushan earthquake and the Wenchuan earthquake显示文摘Following the M w 7.9 Wenchuan earthquake, the M w 6.6 Lushan earthquake is another devastating earthquake that struck the Longmenshan Fault Zone (LFZ) and caused severe damages. In this study, we collected continuous broadband ambient noise seismic data and earthquake event data from Chinese provincial digital seismic network, and then utilized ambient noise tomography method and receiver function method to obtain high resolution shear wave velocity structure, crustal thickness, and Poisson ratio in the earthquake source region and its surroundings. Based on the tomography images and the receiver function results, we further analyzed the deep seismogenic environment of the LFZ and its neighborhood. We reveal three main findings: (1) There is big contrast of the shear wave velocities across the LFZ. (2) Both the Lushan earthquake and the Wenchuan earthquake occurred in the regions where crustal shear wave velocity and crustal thickness change dramatically. The rupture faults and the aftershock zones are also concentrated in the areas where the lateral gradients of crustal seismic wave speed and crustal thickness change significantly, and the focal depths of the earthquakes are concentrated in the transitional depths where shear wave velocities change dramatically from laterally uniform to laterally non-uniform. (3) The Wenchuan earthquake and its aftershocks occurred in low Poisson ratio region, while the Lushan earthquake sequences are located in high Poisson ratio zone. We proposed that the effect of the dramatic lateral variation of shear wave velocity, and the gravity potential energy differences caused by the big contrast in the topography and the crustal thickness across the LFZ may constitute the seismogenic environment for the strong earthquakes in the LFZ, and the Poisson ratio difference between the rocks in the south and north segments of the Longmenshan Fault zone may explain the 5 years delay of the occurrence of the Lushan earthquake than the Wenchuan earthquake.ZHENG Yong GE Can XIE ZuJun YANG YingJie XIONG Xiong HSU HouTze 2013Science China Earth Sciences2013,56,7:37
8Source parameters inversion of the 2013 Lushan earthquake by combining teleseismic waveforms and local seismograms显示文摘On April 20, 2013, a magnitude M s 7.0 earthquake occurred in Lushan, Sichuan Province, China, and caused heavy casualties and economic losses. Based on the local broadband waveforms in Sichuan and adjacent provinces regional networks and teleseismic broadband records from IRIS stations, the focal mechanism and the focal depth are determined by the CAP (Cut And Paste) and its upgraded methods, CAPtele and CAPjoint, respectively. The results show that the focal mechanisms and depth from different methods are steady, and the best double couple solution derived from the joint inversion is 210°, 44°, and 91° for strike, dip, and rake angles respectively for one nodal plane and 29°, 46°, and 89° for another with 16 km focal depth and M w 6.66 moment magnitude. In order to verify the reliability of the results, a number of tests are performed based on local seismograms with different velocity models. They indicate that there is about 10 degree's fluctuation in focal mechanisms and about 2 km variation in focal depth with a complex velocity structure. Furthermore, inverted by re-sampling the teleseismic waveforms on the basis of epicentral distance, the solutions are consistent with each other, which manifests that the teleseismic records are effective for constraining source parameters of the Lushan earthquake.XIE ZuJun JIN BiKai ZHENG Yong GE Can XIONG Xiong XIONG Cheng HSU HouTze 2013Science China Earth Sciences2013,56,7:35

10CYP2C19 polymorphism influences Helicobacter pylori eradication显示文摘The known factors that have contributed to the decline of Helicobacter pylori(H.pylori)eradication rate include antibiotic resistance,poor compliance,high gastric acidity,high bacterial load,and cytochrome P450 2C19(CYP2C19)polymorphism.Proton pump inhibitor(PPI)is important in the eradication regimen.The principal enzyme implicated in the metabolism of PPIs is CYP2C19.The effects of PPI depend on metabolic enzyme,cytochrome P450 enzymes,and CYP2C19 with genetic differences in the activity of this enzyme(the homozygous EM,heterozygous EM(Het EM),and poor metabolizer).The frequency of the CYP2C19 polymorphism is highly varied among different ethnic populations.The CYP2C19genotype is a cardinal factor of H.pylori eradication in patients taking omeprazole-based or lansoprazolebased triple therapies.In contrast,the CYP2C19 polymorphism has no significant effect on the rabeprazolebased or esomeprazole-based triple therapies.The efficacy of levofloxacin-based rescue triple therapy might be also affected by the CYP2C19 polymorphism,but CYP2C19 genotypes did not show obvious impact on other levofloxacin-based rescue therapies.Choice of different PPIs and/or increasing doses of PPIs should be individualized based on the pharmacogenetics background of each patient and pharmacological profile of each drug.Other possible factors influencing gastric acid secretion(e.g.,IL-1β-511 polymorphism)would be also under consideration.Chao-Hung Kuo Chien-Yu Lu Hsiang-Yao Shih Chung-Jung Liu Meng-Chieh Wu Huang-Ming Hu Wen-Hung Hsu Fang-Jung Yu Deng-Chyang Wu Fu-Chen Kuo 2014World Journal of Gastroenterology2014,20,43:33

12Reappraisal of endoscopic papillary balloon dilation for the management of common bile duct stones显示文摘Although endoscopic sphincterotomy(EST) is still considered as a gold standard treatment for common bile duct(CBD) stones in western guideline, endoscopic papillary balloon dilation(EPBD) is commonly used by the endoscopists in Asia as the first-line treatment for CBD stones. Besides the advantages of a technical easy procedure, endoscopic papillary large balloon dilation(EPLBD) can facilitate the removal of large CBD stones.The indication of EPBD is now extended from removal of the small stones by using traditional balloon, to removal of large stones and avoidance of lithotripsy by using large balloon alone or after EST. According to the reports of antegrade papillary balloon dilatation, balloon dilation itself is not the cause of pancreatitis. On the contrary, adequate dilation of papillary orifice can reduce the trauma to the papilla and pancreas by the basket or lithotripter during the procedure of stone extraction. EPLBD alone is as effective as EPLBD with limited EST. Longer ballooning time may be beneficial in EPLBD alone to achieve adequate loosening of papillary orifice. The longer ballooning time does not increase the risk of pancreatitis but may reduce the bleeding episodes in patients with coagulopathy. Slowly inflation of the balloon, but not exceed the diameter of bile duct and tolerance of the patients are important to prevent the complication of perforation. EPBLD alone or with EST are not the sphincter preserved procedures, regular follow up is necessary for early detection and management of CBD stones recurrence.Kwok-Hung Lai Hoi-Hung Chan Tzung-Jiun Tsai Jin-Shiung Cheng Ping-I Hsu 2015World Journal of Gastrointestinal Endoscopy2015,7,2:24
13A new look at anti-Helicobacter pylori therapy显示文摘With the rising prevalence of antimicrobial resistance,the treatment success of standard triple therapy has recently declined to unacceptable levels (i.e.,80% or less) in most countries.Therefore,several treatment regimens have emerged to cure Helicobacter pylori (H.pylori) infection.Novel first-line anti-H.pylori therapies in 2011 include sequential therapy,concomitant quadruple therapy,hybrid (dual-concomitant) therapy and bismuth-containing quadruple therapy.After the failure of standard triple therapy,a bismuth-containing quadruple therapy comprising a proton pump inhibitor (PPI),bismuth,tetracycline and metronidazole can be employed as rescue treatment.Recently,triple therapy combining a PPI,levofloxacin and amoxicillin has been proposed as an alternative to the standard rescue therapy.This salvage regimen can achieve a higher eradication rate than bismuth-containing quadruple therapy in some regions and has less adverse effects.The best second-line therapy for patients who fail to eradicate H.pylori with first-line therapies containing clarithromycin,amoxicillin and metronidazole is unclear.However,a levofloxacin-based triple therapy is an accepted rescue treatment.Most guidelines suggest that patients requiring third-line therapy should be referred to a medical center and treated according to the antibiotic susceptibility test.Nonetheless,an empirical therapy (such as levofloxacin-based or furazolidone-based therapies) can be employed to terminate H.pylori infection if antimicrobial sensitivity data are unavailable.Seng-Kee Chuah Feng-Woei Tsay Ping-I Hsu Deng-Chyang Wu 2011World Journal of Gastroenterology2011,17,35:22
14Timing of mortality in severe acute pancreatitis:Experience from 643 patients显示文摘AIM: To determine the timing of mortality after onset of severe acute pancreatitis (SAP) and the course of the disease in a large series of patients. METHODS: From July 1996 to June 2005, all patients diagnosed with acute pancreatitis at Chang Gung Memorial Hospital, Taipei, Taiwan were retrospectively studied. Three thousand two hundred and fifty episodes of acute pancreatitis were recorded in 2248 patients (1431 males and 817 females; median age, 55.6 years; range, 18-97 years). Mortality was divided into two groups: early death (≤ 14 d after admission), and late death (> 14 d after admission). The clinical features of patients in these two groups were compared. RESULTS: Although the overall mortality rate of acute pancreatitis was 3.8% (123/3250), mortality rate of SAP was as high as 16.3% (105/643). Of those 105 SAP mortalities, 44 (41.9%) deaths occurred within the first 14 d after admission and 61 (58.1%) occurred after14 d. Incidence of early death did not significantly differ from that of late death. The co-morbidities did not contribute to the timing of death. Early deaths mainly resulted from multiple organ failure. Late deaths were mainly caused by secondary complication of infected necrosis. Intra- abdominal bleeding significantly caused higher mortality in late death. CONCLUSION: Approximately half (42%) of SAP deaths occur within 14 d and most were due to multiple organ failure. The late deaths of SAP were mostly due to infected necrosis.Chih-Yuan Fu Chun-Nan Yeh Jun-Te Hsu Yi-Yin Jan Tsann- Long Hwang 2007World Journal of Gastroenterology2007,13,13:21

18Liver metastasis from hepatoid adenocarcinoma of the stomach mimicking hepatocellular carcinoma: Dynamic computed tomography findings显示文摘AIM: To evaluate the dynamic computed tomography(CT) findings of liver metastasis from hepatoid adenocarcinoma of the stomach(HAS) and compared them with hepatocellular carcinoma(HCC).METHODS: Between January 2000 and January 2015, 8 patients with pathologically proven HAS and liver metastases were enrolled. Basic tumor status was evaluated for the primary tumor location and metastatic sites. The CT findings of the liver metastases were analyzed for tumor number and size, presence of tumor necrosis, hemorrhage, venous tumor thrombosis, and dynamic enhancing pattern.RESULTS: The body and antrum were the most common site for primary HAS(n = 7), and observed metastatic sites included the liver(n = 8), lymph nodes(n = 7), peritoneum(n = 4), and lung(n = 2). Most of the liver metastases exhibited tumor necrosis regardless of tumor size. By contrast, tumor hemorrhage was observed only in liver lesions larger than 5 cm(n = 4). Three patterns of venous tumor thrombosis were identified: direct venous invasion by the primary HAS(n = 1), direct venous invasion by the liver metastases(n = 7), and isolated portal vein tumor thrombosis(n = 2). Dynamic CT revealed arterial hyperattenuation and late phase washout in all the liver metastases.CONCLUSION: On dynamic CT, liver metastasis from HAS shared many imaging similarities with HCC. For liver nodules, the presence of isolated portal vein tumor thrombosis and a tendency for tumor necrosis are imaging clues that suggest the diagnosis of HAS.Yang-Yu Lin Chien-Ming Chen Yu-Hsiu Huang Cheng-Yu Lin Sung-Yu Chu Ming-Yi Hsu Kuang-Tse Pan Jeng-Hwei Tseng 2015World Journal of Gastroenterology2015,21,48:17
19Antioxidant and antiglycation properties of different solvent extracts from Chinese olive(Canarium album L.) fruit显示文摘Objective:To evaluate the antioxidant activity,antiglycation property,and bioactivc components content of different solvent extracts from Chinese olive(Canarium album L.) fruit.Methods:The dry powder of Chinese olive fruit was extracted with different solvents,i.e.,water,water/ethanol(1/1,v/v),ethanol,methanol,acetone and ethyl acetate.The total phenolic,total flavonoids and total triterpenoids contents of various extracts were determined by spectrophotometric methods.Phenolic compounds were identified by high performance liquid chromatography.The assayed antioxidant activity was determined in vitro models such as antioxidant capacity by radical scavenging activity using 2,2'-azino-bLs(3-ethylbenzthiazoline-6-sulfonic acid)(ABTS),l,l-diphenyl-2-picryl- hydrazyl(DPPH) and nitrite oxide methods,chelating activity on metal ions,lipid and protein peroxidation methods.In vitro glucosebovine serum albumin assay was used to evaluate the antiglycation of various extracts.Results:The water/ethanol extracts of Chinese olive fruit exerted significant scavenging effects on free radicals and strong inhibitory effects on advanced glycation end products formation.The Chinese olive fruit extracts were rich in phenolic compounds and triterpenoids.Gallic acid,ferulic acid and rutin were identified from the water/ethanol extracts.Correlation analysis indicated that there was a linear relationship between the antioxidant potency,free radical scavenging ability and phenolic compounds content of the Chinese olive fruit extracts.Conclusions:Chinese olive fruit could be a natural candidate for studies of dietary complement to diabetes treatment since it combines antioxidant and antiglycation activities.Chiung-Tsun Kuo Tzu-Hao Liu Tai-Hao Hsu Fang-Yi Lin Hui-Yin Chen 2015Asian Pacific Journal of Tropical Medicine2015,8,12:17
20Mechanisms inactivating the gene for E-cadherin in sporadic gastric carcinomas显示文摘瞄准:为了学习 CDH1/E-cadherin (电子恶棍) 的角色,基因改变介绍在胃的癌(GC ) 在激活在 CDH1 的机制包括变化,杂合现象(LOH ) 的损失,倡导者多型性和 hypermethylation。方法:标本与 GC 从 70 个病人通过手术被收集。Allelotyping PCR 和定序的 LOH,使中毒的高压力液相色谱法和 DNA 的察觉,限制碎片长度多型性分析,甲基化 specific PCR,和免疫组织化学的染色被使用。结果:倡导者多型性不是在激活的电子恶棍的主要机制。仅仅一截断变化在一个弥漫的类型肿瘤(3%) 被发现。LOH 和倡导者 hypermethylation 是在激活的电子恶棍的主要机制,但是有趣地,在 CDH1 的肿瘤和 hypermethylation 在突变而产生之遗传的损失(LOH ) 的部分之间有一个否定协会。因此 LOH 和 hypermethylation 是涉及 GC 的二条不同致瘤的小径。结论:给体细胞突变是极其低的,在 LOH 和 hypermethylation 之间的关系是反的调查结果,这三个因素的任何二联合不能在激活完成 CDH1 的古典二点击的假设。因此,在 transcriptional 水平或在 translational 以后水平操作的另外的机制可能被要求在激活导致 E-cadherin。Yao-Chi Liu Chen-Yang Shen Hurng-Sheng Wu Tsai-Yuan Hsieh De-Chuan Chan Cheng-Jueng Chen Jyh-Cherng Yu Cheng-Ping Yu Horng-Jyh Harn Peng-Jen Chen Chung-Bao Hsieh Teng-Wei Chen Huan-Mieng Hsu 2006World Journal of Gastroenterology2006,12,14:16
