2Diagnosis and management of insulinoma显示文摘Insulinomas,the most common cause of hypoglycemia related to endogenous hyperinsulinism,occur in 1-4 people per million of the general population.Common autonomic symptoms of insulinoma include diaphroresis,tremor,and palpitations,whereas neuroglycopenenic symptoms include confusion,behavioural changes,personality changes,visual disturbances,seizure,and coma.Diagnosis of suspected cases is based on standard endocrine tests,especially the prolonged fasting test.Non-invasive imaging procedures,such as computed tomography and magnetic resonance imaging,are used when a diagnosis of insulinoma has been made to localize the source of pathological insulin secretion.Invasive modalities,such as endoscopic ultrasonography and arterial stimulation venous sampling,are highly accurate in the preoperative localization of insulinomas and have frequently been shown to be superior to noninvasive localization techniques.The range of techniques available for the localization of insulinomas means thatblind resection can be avoided.Intraoperative manual palpation of the pancreas by an experienced surgeon and intraoperative ultrasonography are both sensitive methods with which to finalize the location of insulinomas.A high proportion of patients with insulinomas can be cured with surgery.In patients with malignant insulinomas,an aggressive medical approach,including extended pancreatic resection,liver resection,liver transplantation,chemoembolization,or radiofrequency ablation,is recommended to improve both survival and quality of life.In patients with unresectable or uncontrollable insulinomas,such as malignant insulinoma of the pancreas,several techniques should be considered,including administration of ocreotide and/or continuous glucose monitoring,to prevent hypoglycemic episodes and to improve quality of life.Takehiro Okabayashi Yasuo Shima Tatsuaki Sumiyoshi Akihito Kozuki Satoshi Ito Yasuhiro Ogawa Michiya Kobayashi Kazuhiro Hanazaki 2013World Journal of Gastroenterology2013,19,6:78
3Risk factors for bleeding after endoscopic submucosal dissection for gastric lesions显示文摘AIM:To assess risk factors for bleeding after gastric endoscopic submucosal dissection(ESD) and to develop preventive measures.METHODS:This retrospective study was performed in a tertiary referral center.A total of 328 patients underwent ESD for 398 gastric neoplasms between July 2007 and June 2009.The main outcome was association between post-ESD bleeding and the following:age;sex;comorbidities;daily use of medicine potentially related to gastric injury/bleeding;location,size,and histological depth of lesions;ulceration;experience of operator coagulating the ulcer floor,and duration of operation.We also determined the relationship between the location of post-ESD bleeding and risk factors for hemorrhage.RESULTS:Univariate analysis revealed significant risk factors:tumor location [odds ratio(OR),2.86;95% CI:1.21-6.79,P=0.024],coagulator experience(OR,4.29;95% CI:1.43-12.86,P=0.009),and medicine potentially related to gastric injury/bleeding(OR,2.80;95% CI:1.14-6.90,P=0.039).Multivariate logistic regression analysis confirmed significant,independent risk factors:tumor in lower third of stomach(OR,2.47;95% CI:1.02-5.96,P=0.044),beginner coagulator(OR,3.93;95% CI:1.29-11.9,P=0.016),and medicine(OR,2.76;95% CI:1.09-6.98,P=0.032).We classif ied cases of post-ESD bleeding into two groups(bleeding at the ulcer margin vs bleeding at the center) and found that bleeding at the margin occurred more frequently with beginner coagulators compared with experts(OR,16.00;95% CI:1.22-210.59,P=0.040).CONCLUSION:Beginner coagulators,tumor in the antrum,and medicines were significant risk factors for post-ESD bleeding.Bleeding at the ulcer margin frequently occurred with beginner operators.Yosuke Tsuji Ken Ohata Takafumi Ito Hideyuki Chiba Tomohiko Ohya Toshiaki Gunji Nobuyuki Matsuhashi 2010World Journal of Gastroenterology2010,16,23:60
4Association of Fusobacterium nucleatum with immunity andmolecular alterations in colorectal cancer显示文摘The human intestinal microbiome plays a major role in human health and diseases, including colorectal cancer. Colorectal carcinogenesis represents a heterogeneous process with a differing set of somatic molecular alterations, influenced by diet, environmental and microbial exposures, and host immunity. Fusobacterium species are part of the human oral and intestinal microbiota. Metagenomic analyses have shown an enrichment of Fusobacterium nucleatum(F. nucleatum) in colorectal carcinoma tissue. Using 511 colorectal carcinomas from Japanese patients, we assessed the presence of F. nucleatum. Our results showed that the frequency of F. nucleatum positivity in the Japanese colorectal cancer was 8.6%(44/511), which was lower than that in United States cohort studies(13%). Similar to the United States studies, F. nucleatum positivityin Japanese colorectal cancers was significantly associated with microsatellite instability(MSI)-high status. Regarding the immune response in colorectal cancer, high levels of infiltrating T-cell subsets(i.e., CD3+, CD8+, CD45RO+, and FOXP3+ cells) have been associated with better patient prognosis. There is also evidence to indicate that molecular features of colorectal cancer, especially MSI, influence T-cell-mediated adaptive immunity. Concerning the association between the gut microbiome and immunity, F. nucleatum has been shown to expand myeloid-derived immune cells, which inhibit T-cell proliferation and induce T-cell apoptosis in colorectal cancer. This finding indicates that F. nucleatum possesses immunosuppressive activities by inhibiting human T-cell responses. Certain micro RNAs are induced during the macrophage inflammatory response and have the ability to regulate host-cell responses to pathogens. Micro RNA-21 increases the levels of IL-10 and prostaglandin E2, which suppress antitumor T-cell-mediated adaptive immunity through the inhibition of the antigen-presenting capacities of dendritic cells and T-cell proliferation in colorectal cancer cells. Thus, emerging evidence may provide insights for strategies to target microbiota, immune cells and tumor molecular alterations for colorectal cancer prevention and treatment. Further investigation is needed to clarify the association of Fusobacterium with T-cells and micro RNA expressions in colorectal cancer.Katsuhiko Nosho Yasutaka Sukawa Yasushi Adachi Miki Ito Kei Mitsuhashi Hiroyoshi Kurihara Shinichi Kanno Itaru Yamamoto Keisuke Ishigami Hisayoshi Igarashi Reo Maruyama Kohzoh Imai Hiroyuki Yamamoto Yasuhisa Shinomura 2016World Journal of Gastroenterology2016,22,2:44

12Zircon SHRIMP U-Pb dating on plagiogranite from Kuerti ophiolite in Altay,North Xinjiang显示文摘Field observation, petrological and geochemical characteristics of plagiogranite from Kuerti ophiolite indicate a similar origin to those in shearing zones. It isderived from partial melting of amphibolite that is developed from gabbro within the ocean layer 3 shear zone by the low-angle shearing deformation during the oceanic crustmigrating process. Zircon SHRIMP age of 372±19 Ma for the plagioganite from Kuerti ophiolite indicates that thisophiolite formed in the Devonian period and it alsorepresented the time of extension of the Kuerti backarc basin that is relevant to the northwards subduction of thePaleo-Asian oceanic crust. Therefore, the northwardssubduction of the Paleo-Asian Ocean beneath the Siberian Plate began in the early stage of the Late Paleozoic era.ZHANG Haixiang NIU Hecai Kentaro Terada YU Xueyuan Hiroaki Sato Jun抜chi Ito 2003Chinese Science Bulletin2003,48,20:28
13Randomized controlled trial of pancreatic stenting to prevent pancreatitis after endoscopic retrograde cholangiopancreatography显示文摘AIM:To determine the effectiveness of pancreatic duct(PD) stent placement for the prevention of pancreatitis after endoscopic retrograde cholangiopancreatography(ERCP) in high risk patients.METHODS:Authors conducted a single-blind,randomized controlled trial to evaluate the effectiveness of a pancreatic spontaneous dislodgement stent against post-ERCP pancreatitis,including rates of spontaneous dislodgement and complications.Authors defined high risk patients as having any of the following:sphincter of Oddi dysfunction,difficult cannulation,prior history of post-ERCP pancreatitis,pre-cut sphincterotomy,pancreatic ductal biopsy,pancreatic sphincterotomy,intraductal ultrasonography,or a procedure time of more than 30 min.Patients were randomized to a stent group(n = 60) or to a non-stent group(n = 60).An abdominal radiograph was obtained daily to assessspontaneous stent dislodgement.Post-ERCP pancreatitis was diagnosed according to consensus criteria.RESULTS:The mean age(± standard deviation) was 67.4 ± 13.8 years and the male:female ratio was 68:52.In the stent group,the mean age was 66 ± 13 years and the male:female ratio was 33:27,and in the non-stent group,the mean age was 68 ± 14 years and the male:female ratio was 35:25.There were no significant differences between groups with respect to age,gender,final diagnosis,or type of endoscopic intervention.The frequency of post-ERCP pancreatitis in PD stent and non-stent groups was 1.7%(1/60) and 13.3%(8/60),respectively.The severity of pancreatitis was mild in all cases.The frequency of post-ERCP pancreatitis in the stent group was significantly lower than in the non-stent group(P = 0.032,Fisher's exact test).The rate of hyperamylasemia were 30%(18/60) and 38.3%(23 of 60) in the stent and non-stent groups,respectively(P = 0.05,χ2 test).The placement of a PD stent was successful in all 60 patients.The rate of spontaneous dislodgement by the third day was 96.7%(58/60),and the median(range) time to dislodgement was 2.1(2-3) d.The rates of stent migration,hemorrhage,perforation,infection(cholangitis or cholecystitis) or other complicationss were 0%(0/60),0%(0/60),0%(0/60),0%(0/60),0%(0/60),respectively,in the stent group.Univariate analysis revealed no significant differences in high risk factors between the two groups.The pancreatic spontaneous dislodgement stent safely prevented post-ERCP pancreatitis in high risk patients.CONCLUSION:Pancreatic stent placement is a safe and effective technique to prevent post-ERCP pancreatitis.Therefore authors recommend pancreatic stent placement after ERCP in high risk patients.Yoshiaki Kawaguchi Masami Ogawa Fumio Omata Hiroyuki Ito Tooru Shimosegawa Tetsuya Mine 2012World Journal of Gastroenterology2012,18,14:25
14Criteria for the diagnosis and severity stratification of acute pancreatitis显示文摘Recent diagnostic and therapeutic progress for severe acute pancreatitis(SAP)remarkably decreased the casemortality rate.To further decrease the mortality rate of SAP,it is important to precisely evaluate the severity at an early stage,and initiate appropriate treatment as early as possible.Research Committee of Intractable Diseases of the Pancreas in Japan developed simpler criteria combining routinely available data with clinical signs.Severity can be evaluated by laboratory examinations or by clinical signs,reducing the defect values of the severity factors.Moreover,the severity criteria considered laboratory/clinical severity scores and contrastenhanced computed tomography(CE-CT)findings as independent risk factors.Thus,CE-CT scans are not necessarily required to evaluate the severity of acute pancreatitis.There was no fatal case in mild AP diagnosed by the CE-CT severity score,whereas case-mortality rate in those with SAP was 14.8%.Case-mortality of SAP that fulfilled both the laboratory/clinical and the CE-CT severity criteria was 30.8%.It is recommended,therefore,to perform CE-CT examination to clarify the prognosis in those patients who were diagnosed as SAP by laboratory/clinical severity criteria.Because the mortality rate of these patients with SAP is high,such patients should be transferred to advanced medical units.Makoto Otsuki Kazunori Takeda Seiki Matsuno Yasuyuki Kihara Masaru Koizumi Masahiko Hirota Tetsuhide Ito Keisho Kataoka Motoji Kitagawa Kazuo Inui Yoshifumi Takeyama 2013World Journal of Gastroenterology2013,19,35:24

18Continuous regional arterial infusion therapy with gabexate mesilate for severe acute pancreatitis显示文摘AIM: To evaluate the effi cacy of continuous regional arterial infusion therapy (CRAI) with gabexate mesilate and antibiotics for severe acute pancreatitis (SAP). METHODS: We conducted a prospective study on patients who developed SAP with or without CRAI. Out of 18 patients fulf illed clinical diagnostic criteria for SAP in Japan, 9 patients underwent CRAI, while 9 patients underwent conventional systemic protease inhibitor and antibiotics therapy (non-CRAI). CRAI was initiated within 72 h of the onset of pancreatitis. Gabexate mesilate (2400 mg/d) was continuously administered for 3 to 5 d. The clinical outcome including serum infl ammation-related parameters were examined. RESULTS: The duration of abdominal pain in the CRAI group was 1.9 ± 0.26 d, whereas that in the non-CRAI group was 4.3 ± 0.50. The duration of SIRS in the CRAI group was 2.2 ± 0.22 d, whereas that in the non- CRAI group was 3.2 ± 0.28. Abdominal pain and SIRS disappeared signifi cantly in a short period of time after the initiation of CRAI using gabexate mesilate. The average length of hospitalization signifi cantly differed between the CRAI and non-CRAI groups, 53.3 ± 7.9 d and 87.4 ± 13.9 d, respectively. During the first two weeks, levels of serum CRP and the IL6/IL10 ratio in the CRAI group tended to have a rapid decrease compared to those in the non-CRAI group. CONCLUSION: The present results suggest that CRAI using gabexate mesilate was effective against SAP.Yoshifumi Ino Yoshiyuki Arita Tetsuro Akashi Toshinari Kimura Hisato Igarashi Takamasa Oono Masayuki Furukawa Ken Kawabe Keiichiro Ogoshi Jiro Ouchi Toshihiko Miyahara Ryoichi Takayanagi Tetsuhide Ito 2008World Journal of Gastroenterology2008,14,41:20
19Management of hepatitis B virus infection during treatment for hepatitis B virus-related hepatocellular carcinoma显示文摘Although liver resection is considered the most effective treatment for hepatocellular carcinoma(HCC), treatment outcomes are unsatisfactory because of the high rate of HCC recurrence. Since we reported hepatitis B e-antigen positivity and high serum hepatitis B virus(HBV) DNA concentrations are strong risk factors for HCC recurrence after curative resection of HBV-related HCC in the early 2000 s, many investigators have demonstrated the effects of viral status on HCC recurrence and post-treatment outcomes. These findings suggest controlling viral status is important to prevent HCC recurrence and improve survival after curative treatment for HBV-related HCC. Antiviral therapy after curative treatment aims to improve prognosis by preventing HCC recurrence and maintaining liver function. Therapy with interferon and nucleos(t)ide analogs may be useful for preventing HCC recurrence and improving overall survival in patients who have undergone curative resection for HBV-related HCC. In addition, reactivation of viral replication can occur after liver resection for HBV-related HCC. Antiviral therapy can be recommended for patients to prevent HBV reactivation. Nevertheless, further studies are required to establish treatment guidelines for patients with HBVrelated HCC.Shoji Kubo Shigekazu Takemura Shogo Tanaka Hiroji Shinkawa Takayoshi Nishioka Akinori Nozawa Masahiko Kinoshita Genya Hamano Tokuji Ito Yorihisa Urata 2015World Journal of Gastroenterology2015,21,27:19
20Evolving concepts in bone infection: redefining “biofilm”,“acute vs. chronic osteomyelitis”, “the immune proteome” and “local antibiotic therapy”显示文摘Osteomyelitis is a devastating disease caused by microbial infection of bone. While the frequency of infection following elective orthopedic surgery is low, rates of reinfection are disturbingly high. Staphylococcus aureus is responsible for the majority of chronic osteomyelitis cases and is often considered to be incurable due to bacterial persistence deep within bone. Unfortunately, there is no consensus on clinical classifications of osteomyelitis and the ensuing treatment algorithm. Given the high patient morbidity,mortality, and economic burden caused by osteomyelitis, it is important to elucidate mechanisms of bone infection to inform novel strategies for prevention and curative treatment. Recent discoveries in this field have identified three distinct reservoirs of bacterial biofilm including: Staphylococcal abscess communities in the local soft tissue and bone marrow, glycocalyx formation on implant hardware and necrotic tissue, and colonization of the osteocyte-lacuno canalicular network(OLCN) of cortical bone. In contrast, S.aureus intracellular persistence in bone cells has not been substantiated in vivo, which challenges this mode of chronic osteomyelitis. There have also been major advances in our understanding of the immune proteome against S. aureus, from clinical studies of serum antibodies and media enriched for newly synthesized antibodies(MENSA), which may provide new opportunities for osteomyelitis diagnosis, prognosis, and vaccine development. Finally, novel therapies such as antimicrobial implant coatings and antibiotic impregnated 3D-printed scaffolds represent promising strategies for preventing and managing this devastating disease. Here, we review these recent advances and highlight translational opportunities towards a cure.Elysia A. Masters Ryan P. Trombetta Karen L. de Mesy Bentley Brendan F Boyce Ann Lindley Gill Steven R.
