| 2 | Portal vein thrombosis in liver cirrhosis显示文摘Portal vein thrombosis(PVT) is considered to be a frequent complication of liver cirrhosis. However, unlike PVT in patients without cirrhosis, very few data are available on the natural history and management of PVT in cirrhosis, despite its association with potentially life-threatening conditions, such as gastroesophageal bleeding and acute intestinal ischemia. Moreover, no consensus regarding PVT in cirrhosis exists. Suggested causes of PVT in cirrhosis include reduced portal blood flow velocity, multiple congenital or acquired thrombophilic factors, inherited or acquired conditions, and derangement of liver architecture. However, the understanding of PVT in cirrhosis is incomplete. In addition, information on the management of PVT in cirrhosis is inadequate. The aims of this review are to:(1) assemble data on the physiopathological mechanism, clinical findings, diagnosis and management of PVT in cirrhosis;(2) describe the principal factors most frequently involved in PVT development; and(3) summarize the recent knowledge concerning diagnostic and therapeutic procedures. | Nao Kinjo Hirofumi Kawanaka Tomohiko Akahoshi Yoshi-hiro Matsumoto Masahiro Kamori Yoshihiro Nagao Naotaka Hashimoto Hideo Uehara Morimasa Tomikawa Ken Shirabe Yoshihiko Maehara | 2014 | World Journal of Hepatology2014,6,2: | 38 |

| 4 | Depletion of CD25^+CD4^+T cells (Tregs) enhances the HBV-specific CD8^+ T cell response primed by DNA immunization显示文摘AIM: Persistent hepatitis B virus (HBV) infection is characterized by a weak CD8+ T cell response to HBV. Immunotherapeutic strategies that overcome tolerance and boost these suboptimal responses may facilitate viral clearance in chronically infected individuals. Therefore, we examined whether CD25+CD4+ regulatory T (Treg) cells might be involved in a inhibition of CD8+T cell priming or in the modulation of the magnitude of the'peak' antiviral CD8+ T cell response primed by DNA immunization. METHODS: B10.D2 mice were immunized once with plasmid pCMV-S. Mice received 500 μg of anti-CD25 mAb injected intraperitoneally 3 d before DNA immunization to deplete CD25+ cells. Induction of HBV-specific CD8+ T ceils in peripheral blood mononuclear cells (PBMCs) was measured by S28-39 peptide loaded DimerX staining and their function was analyzed by intracellular IFN-γ staining.RESULTS: DNA immunization induced HBV-specific CD8+ T cells. At the peak T cell response (d 10), 7.1±2.0% of CD8+ T cells were HBV-specific after DNA immunization, whereas 12.7±3.2% of CD8+ T cells were HBV-specific in Treg-depleted mice, suggesting that DNA immunization induced more antigen-specific CD8+ T cells in the absence of CD25+ Treg cells (n = 6, P<0.05). Similarly, fewer HBVspecific memory T cells were detected in the presence of these cells (1.3±0.4%) in comparison to Treg-depleted mice (2.6±0.9%) on d 30 after DNA immunization (n = 6, P<0.01). Both IFN-γ production and the avidity of the HBV-specific CD8+ T cell response to antigen were higher in HBV-specific CD8+ T cells induced in the absence of Treg cells.CONCLUSION: CD25+ Treg cells suppress priming and/or expansion of antigen-specific CD8+ T cells during DNA immunization and the peak CD8+ T cell response is enhanced by depleting this cell population. Furthermore, Treg cells appear to be involved in the contraction phase of the CD8+ T ceil response and may affect the quality of memory T cell pools. The elimination of Treg cells or their inhibition may be important in immunotherapeutic strategies to control HBV infection by inducing virus-specific cytotoxic T lymphocyte responses in chronically infected subjects. | Yoshihiro Furuichi Hirotake Tokuyama Satoshi Ueha Makoto Kurachi Fuminori Moriyasu Kazuhiro Kakimi | 2005 | World Journal of Gastroenterology2005,11,24: | 30 |
| 5 | Initial management for acute lower gastrointestinal bleeding显示文摘Acute lower gastrointestinal bleeding(LGIB) is a common indication for hospital admission. Patients with LGIB often experience persistent or recurrent bleeding and require blood transfusions and interventions, such as colonoscopic,radiological, and surgical treatments. Appropriate decision-making is needed to initially manage acute LGIB, including emergency hospitalization, timing of colonoscopy, and medication use. In this literature review, we summarize the evidence for initial management of acute LGIB. Assessing various clinical factors,including comorbidities, medication use, presenting symptoms, vital signs, and laboratory data is useful for risk stratification of severe LGIB, and for discriminating upper gastrointestinal bleeding. Early timing of colonoscopy had the possibility of improving identification of the bleeding source, and the rate of endoscopic intervention, compared with elective colonoscopy. Contrast-enhanced computed tomography before colonoscopy may help identify stigmata of recent hemorrhage on colonoscopy, particularly in patients who can be examined immediately after the last hematochezia. How to deal with nonsteroidal antiinflammatory drugs(NSAIDs) and antithrombotic agents after hemostasis should be carefully considered because of the risk of rebleeding and thromboembolic events. In general, aspirin as primary prophylaxis for cardiovascular events and NSAIDs were suggested to be discontinued after LGIB. Managing acute LGIB based on this information would improve clinical outcomes. Further investigations are needed to distinguish patients with LGIB who require early colonoscopy and hemostatic intervention. | Tomonori Aoki Yoshihiro Hirata Atsuo Yamada Kazuhiko Koike | 2019 | World Journal of Gastroenterology2019,25,1: | 28 |

| 7 | Risk factors for bleeding after endoscopic mucosal resection显示文摘AIM: To clarify the risk factors for bleeding after endoscopic mucosal resection (EMR).METHODS: A total of 297 consecutive patients who underwent EMR were enrolled. Some of the patients had multiple lesions. Bleeding requiring endoscopic treatment was defined as bleeding after EMR. Odds ratios (OR) with 95% confidence intervals (CI), calculated by logistic regression with multivariate adjustments for covariates,were the measures of association.RESULTS: Of the 297 patients, 57 (19.2%) patients with bleeding after EMR were confirmed. With multivariate adjustment, the cutting method of ENR, diameter, and endoscopic pattern of the tumor were associated with the risk of bleeding after ENR. The multivariate-adjusted OR for bleeding after EMR using endoscopic aspiration mucosectomy was 3.07 (95%CI, 1.59-5.92) compared with strip biopsy. The multiple-adjusted OR for bleeding after EMR for the highest quartile (16-50 mm) of tumor diameter was 5.63 (95%CI, 1.84-17.23) compared with that for the lowest (4-7 mm). The multiple-adjusted OR for bleeding after EM R for depressed type of tumor was 4.21 (95%CI, 1.75-10.10) compared with elevated type.CONCLUSION: It is important to take tumor characteristics (tumor size and endoscopic pattern) and cutting method of EMR into consideration in predicting bleeding after ENR. | Masatsugu Shiba Kazuhide Higuchi Kaori Kadouchi Ai Montani Kazuki Yamamori Hirotoshi Okazaki Makiko Taguchi Tomoko Wada Atsushi Itani Toshio Watanabe Kazunari Tominaga Yoshihiro Fujiwara Tomoshige Hayashi Kei Tsumura Tetsuo Arakawa | 2005 | World Journal of Gastroenterology2005,11,46: | 25 |
| 8 | Characteristics and predictors of gastric cancer after Helicobacter pylori eradication显示文摘Helicobacter pylori(H. pylori) eradication can reduce gastric cancer. However, gastric cancer still develops after eradication, and cases who received eradication therapy are increasing. In this study, we have reviewed the characteristics and predictors of primary gastric cancer developing after H. pylori eradication. In terms of the characteristics, endoscopic, histologic, and molecular characteristics are reported. Endoscopically, gastric cancer after eradication is often depressedtype and shows a gastritis-like appearance, which sometimes makes the diagnosis difficult. Histologically, most gastric cancer after eradication is intestinal type, and non-neoplastic epithelium, also called epithelium with low-grade atypia, is frequently seen over the tumor, which is presumably the cause of the endoscopic gastritis-like appearance. As for molecular characteristics, some markers, such as Ki67, MUC2, and Wnt5a expression, are lower in cancer from patients in whom H. pylori has been eradicated. In terms of predictors, several Japanese studies have reported that severe endoscopic atrophy at eradication is a risk factor for gastric cancer development. Histologic intestinal metaplasia, especially in the corpus, and long-term use of proton pump inhibitors, are also reported as risk factors for gastric cancer after H. pylori eradication. These studies on the characteristics and predictors of gastric cancer development will become the cornerstone for establishing a novel surveillance program based on the gastric cancer risk stratification specific to H. pylori-eradicated patients. | Satoki Shichijo Yoshihiro Hirata | 2018 | World Journal of Gastroenterology2018,24,20: | 25 |
| 9 | Water isotope variations in the snow pack and summer precipitation at July 1 Glacier, Qilian Mountains in northwest China显示文摘This paper presents the stable isotope data of the snow pack and summer precipitation collected at the July 1 Glacier, Qilian Mountains in northwest China and analyses their relationships with meteorologi- cal factors. On an event scale, there is no temperature effect on the δ 18O values in the summer pre- cipitation, whereas the amount effect is shown to be clear. By tracing the moisture transport history and comparing the precipitation with its isotopic composition, it is shown that this amount effect not only reflects the change in moisture trajectory, which is related to the monsoon activities, but is also associated with the cooling degree of vapor in the cloud, the evaporation of falling raindrops and the isotopic exchange between the falling drops and the atmospheric vapor. As very little precipitation occurs in winter, the snow pack profile mainly represents the precipitation in the other three seasons. There are low precipitation δ 18O ratios in summer and high ratios in spring and autumn. The Meteoric Water Line (MLW) for the summer precipitation is δ D = 7.6 δ 18O + 13.3, which is similar to that at Delingha, located in the south rim of the Qilian Mountains. The MWL for the snow pack is δ D = 10.4 δ 18O + 41.4, showing a large slope and intercept. The deuterium excess (d) of the snow pack is positively correlated with δ 18O, indicating that both d and δ 18O decrease from spring to summer and increase from early autumn to early spring. This then results in the high slope and intercept of the MWL. Sea- sonal fluctuations of d in the snow pack indicate the change of moisture source and trajectory. During spring and autumn, the moisture originates from continental recycling or rapid evaporation over rela- tively warm water bodies like Black, Caspian and Aral Seas when the dry westerly air masses pass over them, hence very high d values in precipitation are formed. During summer, the monsoon is responsi- ble for the low d values. This indicates that the monsoon can reach the western part of the Qilian Mountains. | ZHOU ShiQiao NAKAWO Masayoshi SAKAI Akiko MATSUDA Yoshihiro DUAN KeQin PU JianChen | 2007 | Chinese Science Bulletin2007,52,21: | 21 |

| 12 | Role of 18F-fluorodeoxyglucose positron emission tomography imaging in surgery for pancreatic cancer显示文摘AIM: To evaluate the role of positron emission tomo-graphy using 18F-fluorodeoxyglucose (FDG-PET) in the surgical management of patients with pancreatic cancer, including the diagnosis, staging, and selection of patients for the subsequent surgical treatment.METHODS: This study involved 53 patients with proven primary pancreatic cancer. The sensitivity of diagnosing the primary cancer was examined for FDG-PET, CT, cytological examination of the bile or pancreatic juice, and the serum levels of carcinoembrionic antigens (CEA) and carbohydrate antigen 19-9 (CA19-9). Next, the accuracy of staging was compared between FDG-PET and CT. Finally, FDG-PET was analyzed semiquantitatively using the standard uptake value (SUV). The impact of the SUV on patient management was evaluated by examining the correlations between the SUV and the histological findings of cancer.RESULTS: The sensitivity of FDG-PET, CT, cytological examination of the bile or pancreatic juice, and the serum levels of CEA and CA19-9 were 92.5%, 88.7%, 46.4%, 37.7% and 69.8%, respectively. In staging, FDG-PET was superior to CT only in diagnosing distant disease (bone metastasis). For local staging, the sensitivity of CT was better than that of FDG-PET. The SUV did not correlate with the pTNM stage, grades, invasions to the vessels and nerve, or with the size of the tumor. However, there was a statistically significant difference (4.6 ± 2.9 vs 7.8 ± 4.5, P = 0.024) in the SUV between patients with respectable and unresectable disease.CONCLUSION: FDG-PET is thus considered to be useful in the diagnosis of pancreatic cancer. However, regarding the staging of the disease, FDG-PET is not considered to be a sufficiently accurate diagnostic modality. Although the SUV does not correlate with the patho-histological prognostic factors, it may be useful in selecting patients who should undergo subsequent surgical treatment. | Hisao Wakabayashi Yoshihiro Nishiyama Tsuyoshi Otani Takanori Sano Shinichi Yachida Keiichi Okano Kunihiko Izuishi Yasuyuki Suzuki | 2008 | World Journal of Gastroenterology2008,14,1: | 16 |
| 13 | Controversies regarding and perspectives on clinical utility of biomarkers in hepatocellular carcinoma显示文摘The prevalence of hepatocellular carcinoma(HCC)worldwide parallels that of persistent infection with the hepatitis B virus(HBV)and/or hepatitis C virus(HCV).According to recommendations by the World Health Organization guidelines for HBV/HCV,alpha-fetoprotein(AFP)testing and abdominal ultrasound should be performed in routine surveillance of HCC every 6 mo for high-risk patients.These examinations have also been recommended worldwide by many other HCC guidelines over the past few decades.In recent years,however,the role of AFP in HCC surveillance and diagnosis has diminished due to advances in imaging modalities.AFP was excluded from the surveillance and/or diagnostic criteria in the HCC guidelines published by the American Association for the Study of Liver Diseases in 2010,the European Association for the Study of the Liver in 2012,and the National Comprehensive Cancer Network in 2014.Other biomarkers,including the Lens culinaris agglutinin-reactive fraction of AFP(AFP-L3),des-γ-carboxyprothrombin,Dickkopf-1,midkine,and micro RNA,are being studied in this regard.Furthermore,increasing attention has focused on the clinical utility of biomarkers as pre-treatment predictors for tumor recurrence and as post-treatment monitors.Serum and tissue-based biomarkers and genomics may aid in the diagnosis of HCC,determination of patient prognosis,and selection of appropriate treatment.However,further studies are needed to better characterize the accuracy and potential role of these approaches in clinical practice. | Pei-Pei Song Ju-Feng Xia Yoshinori Inagaki Kiyoshi Hasegawa Yoshihiro Sakamoto Norihiro Kokudo Wei Tang | 2016 | World Journal of Gastroenterology2016,22,1: | 15 |

| 15 | Dietary polyphenols and colorectal cancer risk:The Fukuoka colorectal cancer study显示文摘AIM:To investigate the associations between dietary intake of polyphenols and colorectal cancer. METHODS:The study subjects were derived from the Fukuoka colorectal cancer study, a community-based case-control study. The study subjects were 816 cases of colorectal cancer and 815 community-based controls. The consumption of 148 food items was assessed by a computer-assisted interview. We used the consumption of 97 food items to estimate dietary intakes of total, tea and coffee polyphenols. The Phenol-Explorer database was used for 92 food items. Of the 5 foods which were not listed in the Phenol-Explorer Database, polyphenol contents of 3 foods (sweet potatoes, satoimo and daikon) were based on a Japanese study and 2 foods (soybeans and fried potatoes) were estimated by ORAC-based polyphenol contents in the United States Department of Agriculture Database. Odds ratios (OR) and 95%CI of colorectal cancer risk according to quintile categories of intake were obtained by using logistic regression models with adjustment for age, sex, residential area, parental history of colorectal cancer, smoking, alcohol consumption, body mass index 10 years before, type of job, leisure-time physical activity and dietary intakes of calcium and n-3 polyunsaturated fatty acids.RESULTS:There was no measurable difference in total or tea polyphenol intake between cases and controls, but intake of coffee polyphenols was lower in cases than in controls. The multivariate-adjusted OR of colorectal cancer according to quintile categories of coffee polyphenols (from the first to top quintile) were 1.00 (referent), 0.81 (95%CI:0.60-1.10), 0.65 (95%CI:0.47-0.89), 0.65 (95%CI:0.46-0.89) and 0.82 (95%CI:0.60-1.10), respectively (P trend = 0.07). Similar, but less pronounced, decreases in the OR were also noted for the third and fourth quintiles of total polyphenol intake. Tea polyphenols and non-coffee polyphenols showed no association with colorectal cancer risk. The sitespecific analysis, based on 463 colon cancer cases and 340 rectal cancer cases, showed an inverse association between coffee polyphenols and colon cancer. The multivariate-adjusted OR of colon cancer for the first to top quintiles of coffee polyphenols were 1.00 (referent), 0.92 (95%CI:0.64-1.31), 0.75 (95%CI:0.52-1.08), 0.69 (95%CI:0.47-1.01), and 0.68 (95%CI:0.46-1.00), respectively (P trend = 0.02). Distal colon cancer showed a more evident inverse association with coffee polyphenols than proximal colon cancer. The association between coffee polyphenols and rectal cancer risk was U -shaped, with significant decreases in the OR at the second to fourth quintile categories. There was also a tendency that the OR of colon and rectal cancer decreased in the intermediate categories of total polyphenols. The decrease in the OR in the intermediate categories of total polyphenols was most pronounced for distal colon cancer. Intake of tea polyphenols was not associated with either colon or rectal cancer. The associations of coffee consumption with colorectal, colon and rectal cancers were almost the same as observed for coffee polyphenols. The trend of the association between coffee consumption and colorectal cancer was statistically significant. CONCLUSION:The present findings suggest a decreased risk of colorectal cancer associated with coffee consumption. | Zhen-Jie Wang Keizo Ohnaka Makiko Morita Kengo Toyomura Suminori Kono Takashi Ueki Masao Tanaka Yoshihiro Kakeji Yoshihiko Maehara Takeshi Okamura Koji Ikejiri Kitaroh Futami Takafumi Maekawa Yohichi Yasunami Kenji Takenaka Hitoshi Ichimiya Reiji Terasaka | 2013 | World Journal of Gastroenterology2013,19,17: | 12 |
| 16 | NF-κB and ERK-signaling pathways contribute to the gene expression induced by cag PAI-positive-Helicobacter pylori infection显示文摘AIM: To elucidate the sequential gene expression profile in AGS cells co-cultured with wild-type Hellcobacter pylori (Hpylon) as a model of H pylori-infected gastric epithelium, and to further examine the contribution of cag-pathogenicity islands (cagPAI)-coding type Ⅳ secretion system and the two pathways, nuclear factor kappa B (NF-κB) and extracellular signal-regulated kinases (ERK) on wild-type H pylori-induced gene expression. METHODS: Gene expression profiles induced by H pylori were evaluated in AGS gastric epithelial cells using cDNA microarray, which were present in the 4 600 independent clones picked up from the human gastric tissue. We also analyzed the contribution of NF-κB and ERK signaling on H pylori-induced gene expression by using inhibitors of specific signal pathways. The isogenic mutant with disrupted capE (△cagE) was used to elucidate the role of capPAI-encoding type Ⅳ secretion system in the gene expression profile. RESULTS: According to the expression profile, the genes were classified into four clusters. Among them, the clusters characterized by continuous upregulation were most conspicuous, and it contained many signal transducer activity-associated genes. The role of cagPAI on cultured cells was also investigated using isogenic mutant cagE, which carries non-functional cagPAI. Then the upregulation of more than 80% of the induced genes (476/566) was found to depend on cagPAI. Signal transducer pathway through NF-κB or ERK are the major pathways which are known to be activated by cagPAI-positive H pylori. The role of these pathways in the whole signal activation by cagPAI- positive H pylori was analyzed. The specific inhibitors against NF-κB or ERK pathway blocked the activation of gene expression in 65% (367/566) or 76% (429/566) of the genes whose activation appealed to depend on cagPAI. CONCLUSION: These results suggest that more than half of the genes induced by cagPAI-positive H pylori depend on NF-κB and ERK signaling activation, and these pathways may play a role in the gene expression induced by host-bacterial interaction which may associate with H pylori-related gastro-duodenal diseases. | Wataru Shibata Yoshihiro Hirata Haruhiko Yoshida Motoyuki Otsuka Yujin Hoshida Keiji Ogura Shin Maeda Tomoya Ohmae Ayako Yanai Yuzo Mitsuno Naohiko Seki Takao Kawabe Masao Omata | 2005 | World Journal of Gastroenterology2005,11,39: | 12 |
| 17 | ^(18)F-fluorodeoxyglucose positron emission tomography in the diagnosis of small pancreatic cancer显示文摘AIM:To investigate the role of 18 F-fluorodeoxyglucose positron emission tomography(FDG-PET) in the diagnosis of small pancreatic cancer. METHODS:This study involved 31 patients with proven invasive ductal cancer of the pancreas.The patients were divided into 3 groups according to the maximum diameter of the tumor:TS1(maximum tumor size≤2.0 cm) ,TS2(>2.0 cm and≤4.0 cm) or TS3-4(>4.0 cm) .The relationships between the TS and various diagnostic tools,including FDG-PET with dual time point evaluation,were analyzed. RESULTS:The tumors ranged from 1.3 to 11.0 cm in diameter.Thirty of the 31 patients(97%) had a positive FDG-PET study.There were 5 patients classified as TS1,15 as TS2 and 11 as TS3-4.The sensitivity of FDG-PET,computed tomography(CT) and magnetic resonanceimaging(MRI) were 100%,40%,0%in TS1,93%,93%,89%in TS2 and 100%,100%,100%in TS3-4. The sensitivity of FDG-PET was significantly higher in comparison to CT and MRI in patients with TS1(P< 0.032) .The mean standardized uptake values(SUVs) did not show a significant difference in relation to the TS(TS1:5.8±4.5,TS2:5.7±2.2,TS3-4:8.2±3.9) ,respectively.All the TS1 tumors(from 13 to 20 mm) showed higher SUVs in FDG-PET with dual time point evaluation in the delayed phase compared with the early phase,which suggested the lesions were malignant. CONCLUSION:These results indicate that FDG-PET with dual time point evaluation is a useful modality for the detection of small pancreatic cancers with a diameter of less than 20 mm. | Keiichi Okano Keitaro Kakinoki Shintaro Akamoto Masanobu Hagiike Hisashi Usuki Yuka Yamamoto Yoshihiro Nishiyama Yasuyuki Suzuki | 2011 | World Journal of Gastroenterology2011,17,2: | 12 |

RESULTS:The sensitivity and specificity for abnormal branch pancreatic ducts determined by two reviewers were respectively 55%-63% and 75%-83% in the head, 57%-64% and 82%-83% in the body, and 44%-44% and 72%-76% in the tail of the pancreas. The sensitivity and specificity for mild chronic pancreatitis were 56%-63% and 92%-92%, respectively. Interobserver agreement (κ statistics) concerning the diagnosis of an abnormal branch pancreatic duct and of mild chronic pancreatitis was good to excellent. CONCLUSION:Secretin injection-MRCP might be useful for the diagnosis of mild chronic pancreatitis. | Masafumi Suyama Yoshihiro Kubokawa Sumio Watanabe | 2008 | World Journal of Gastroenterology2008,14,8: | 11 |
