| 2 | Intraductal neoplasm of the intrahepatic bile duct: Clinicopathological study of 24 cases显示文摘AIM: To investigate the clinicopathological features of intraductal neoplasm of the intrahepatic bile duct (INihB). METHODS: Clinicopathological features of 24 cases of INihB, which were previously diagnosed as biliary papillomatosis or intraductal growth of intrahepatic biliary neoplasm, were reviewed. Mucin immunohistochemistry was performed for mucin (MUC)1, MUC2, MUC5AC and MUC6. Ki-67, P53 and β-catenin immunoreactivity were also examined. We categorized each tumor as adenoma (low grade), borderline (intermediate grade), and malignant (carcinoma in situ , high grade including tumors with microinvasion). RESULTS: Among 24 cases of INihB, we identified 24 tumors. Twenty of 24 tumors (83%) were composed of a papillary structure; the same feature observed in intraductal papillary neoplasm of the bile duct (IPNB). In contrast, the remaining four tumors (17%) showed both tubular and papillary structures. In three of the four tumors (75%), macroscopic mucin secretion was limited but microscopic intracellular mucin was evident. Histologically, 16 tumors (67%) were malignant, three (12%) were borderline, and five (21%) were adenoma. Microinvasion was found in four cases (17%). Immunohistochemical analysis revealed that MUC1 was not expressed in the borderline/adenoma group but was expressed only in malignant lesions (P = 0.0095). Ki-67 labeling index (LI) was significantly higher in the malignant group than in the borderline/adenoma group (22.2 ± 15.5 vs 7.5 ± 6.3, P < 0.01). In the 16 malignant cases, expression of MUC5AC showed borderline significant association with high Ki-67 LI (P = 0.0622). Nuclear expression of β-catenin was observed in two (8%) of the 24 tumors, and these two tumors also showed MUC1 expression. P53 was negative in all tumors. CONCLUSION: Some cases of INihB have a tubular structure, and are subcategorized as IPNB with tubular structure. MUC1 expression in INihB correlates positively with degree of malignancy. | Yoshiki Naito Hironori Kusano Osamu Nakashima Eiji Sadashima Satoshi Hattori Tomoki Taira Akihiko Kawahara Yoshinobu Okabe Kazuhide Shimamatsu Jun Taguchi Seiya Momosaki Koji Irie Rin Yamaguchi Hiroshi Yokomizo Michiko Nagamine Seiji Fukuda Shinichi Sugiyama Naoyo Nishida Koichi Higaki Munehiro Yoshitomi Masafumi Yasunaga Koji Okuda Hisafumi Kinoshita Masayoshi Kage Masamichi Nakayama Makiko Yasumoto Jun Akiba Hirohisa Yano | 2012 | World Journal of Gastroenterology2012，18，28： | 16 |
| 3 | 早胃的癌症用的程度的诊断灵活光谱成像颜色改进显示文摘 The demarcation line between the cancerous lesion and the surrounding area could be easily recognized with flexible spectral imaging color enhancement (FICE) system compared with conventional white light images. The characteristic f inding of depressed-type early gastric cancer (EGC) in most cases was revealed as reddish lesions distinct from the surrounding yellowish non-cancerous area without magnification. Conventional endoscopic images provide little information regarding depressed lesions located in the tangential line, but FICE produces higher color contrast of such cancers. Histological f indings in depressed area with reddish col- or changes show a high density of glandular structure and an apparently irregular microvessel in intervening parts between crypts, resulting in the higher color con- trast of FICE image between cancer and surrounding area. Some depressed cancers are shown as whitish lesion by conventional endoscopy. FICE also can pro- duce higher color contrast between whitish cancerous lesions and surrounding atrophic mucosa. For nearly flat cancer, FICE can produce an irregular structuralpattern of cancer distinct from that of the surrounding mucosa, leading to a clear demarcation. Most elevated-type EGCs are detected easily as yellowish lesions with clearly contrasting demarcation. In some cases, a partially reddish change is accompanied on the tumor surface similar to depressed type cancer. In addition, the FICE system is quite useful for the detection of minute gastric cancer, even without magnif ication. These new contrasting images with the FICE system may have the potential to increase the rate of detection of gastric cancers and screen for them more effectively as well as to determine the extent of EGC. | Hiroyuki Osawa Hironori Yamamoto Yoshimasa Miura Mitsuyo Yoshizawa Keijiro Sunada Kiichi Satoh Kentaro Sugano | 2012 | World Journal of Gastrointestinal Endoscopy2012，4，8： | 11 |

| 5 | Elevation of the glycated albumin to glycated hemoglobin ratio during the progression of hepatitis C virus related liver fibrosis显示文摘AIM: To analyze the relationship between the glycated albumin (GA) to glycated hemoglobin (HbA1c) ratio and the histological grading of liver fibrosis.METHODS: The study retrospectively included consecutive hepatitis C virus positive chronic liver disease patients (n = 142) who had undergone percutaneous liver biopsy between January 2008 and March 2010 at our institution. The ratios of GA/HbA1c were calculated in all patients to investigate the relationship with the degree of the liver fibrosis. The values of the aspartate aminotransferase-to-platelet ratio index (APRI), an excellent marker for the evaluation of liver fibrosis, were also calculated. In addition, we combined the ratio of GA/HbA1c and the APRI in order to improve our ability to detect the presence of significant liver fibrosis. RESULTS: Sixty-one (43%) patients had either no fibrosis or minimal fibrosis (METAVIR score: F0-F1), while 25 (17%) had intermediate fibrosis (F2). Fifty-six (39%) patients had severe fibrosis (F3-F4) and 27 of them had cirrhosis (F4). The mean values of the GA/HbA1c increased with the progression of the fibrosis (F0-1: 2.83 ± 0.24, F2: 2.85 ± 0.24, F3: 2.92 ± 0.35, F4: 3.14 ± 0.54). There was a significant dif- ference between the F0-F1 vs F4, F2 vs F4, and F3 vs F4 groups (P < 0.01, P < 0.01, P < 0.01 and P < 0.05, respectively). The GA/HbA1c ratio was significantly higher in the patients with cirrhosis (F4) than in those without cirrhosis (F0-F3) (3.14 ± 0.54 vs 2.85 ± 0.28, P < 0.0001). The GA/HbA1c ratio was also significantly higher in the patients with severe fibrosis (F3-F4) than in those without severe liver fibrosis (F0-F2) (3.03 ± 0.41 vs 2.84 ± 0.24, P < 0.001). Furthermore, the GA/ HbA1c ratio was also significantly higher in the patients with significant fibrosis (F2-F4) than in those without significant liver fibrosis (F0-F1) (2.98 ± 0.41 vs 2.83 ± 0.24, P < 0.001). The diagnostic performance of the increased GA/HbA1c ratio (> 3.0) was as follows: its sensitivity and specificity for the detection of liver cirrhosis (F4) were 59.3% and 70.4%, respectively and its sensitivity and specificity for the detection of severe liver fibrosis (F3-F4) were 50.0% and 74.4%,respectively. With regard to the detection of significant fibrosis (F2-F4), its sensitivity was 44.4% and its specificity was 77.0%. Although even the excellent marker APRI shows low sensitivity (25.9%) for distinguishing patients with or without significant fibrosis, the combination of the APRI and GA/HbA1c ratio increased the sensitivity up to 42.0%, with only a modest decrease in the specificity (from 90.2% to 83.6%). CONCLUSION: The GA/HbA1c ratio increased in line with the histological severity of liver fibrosis, thus suggesting that this ratio is useful as a supportive index of liver fibrosis. | Nobuhiro Aizawa Hirayuki Enomoto Hiroyasu Imanishi Masaki Saito Yoshinori Iwata Hironori Tanaka Naoto Ikeda Yoshiyuki Sakai Tomoyuki Takashima Takashi Iwai Ei-ichiro Moriwaki Soji Shimomura Hiroko Iijima Hideji Nakamura Shuhei Nishiguchi | 2012 | World Journal of Hepatology2012，4，1： | 10 |

| 7 | Medical management of gastric cancer:A 2014 update显示文摘Gastric cancer represents a serious health problem on a global scale. It is the second leading cause of cancer-related death worldwide. Novel therapeutic targets are desperately needed because the meager improvement in the cure rate of about 10% realized by adjunctive treatments to surgery is unacceptable as > 50% patients with localized gastric cancer succumb to their disease. Either postoperative chemoradiotherapy(United States),pre-and post-operative chemotherapy(Europe),and adjuvant chemotherapy after a D2 resection(Asia) can all be regarded as standards of care in the localized gastric cancer management. In metastatic disease the addition of trastuzumab to chemotherapy is standard of care in Her2 positive disease. In the HER2 negative population,the treatments remain limited.In the first line setting,the standard of care is a combination of fluoropyrimidine and platinum containing chemotherapy,with or without epirubicin or docetaxel.The results of targeted therapy trials have by and large been disappointing,but none of these trials looked at an appropriately enriched population.Finally there is a meager overall survival benefit in treating patients with metastatic disease in the second line setting,with either irinotecan,docetaxel or ramucirumab however none of these drugs have been compared head to head in a well-powered randomized controlled trial. | Elena Elimova Hironori Shiozaki Roopma Wadhwa Kazuki Sudo Qiongrong Chen Jeannelyn S Estrella Mariela A Blum Brian Badgwell Prajnan Das Shumei Song Jaffer A Ajani | 2014 | World Journal of Gastroenterology2014，20，38： | 10 |
| 8 | Is hepatic arterial infusion chemotherapy effective treatment for advanced hepatocellular carcinoma resistant to transarterial chemoembolization?显示文摘AIM:To evaluate the effectiveness of hepatic arterial infusion chemotherapy(HAIC) for advanced hepatocellular carcinoma(HCC) resistant to transarterial chemoembolization(TACE).METHODS:This study was conducted on 42 patients who received HAIC for advanced HCC between 2001and 2010 at our hospital.5-fluorouracil(5-FU) was administered continuously for 24 h from day 1 to day 5 every 2-4 wk via an injection reservoir.Intra-arterial cisplatin or subcutaneous interferon was administered in combination with the 5-FU.The patients enrolled in this retrospective study were divided into two groups according to whether or not they fulfilled the criteria for resistance to TACE proposed by the Japan Society of Hepatology in 2010(written in Japanese);one group of patients who did not fulfill the criteria for TACE resistance(group A,n = 23),and another group who fulfilled the criteria for TACE resistance(group B,n = 19).We compared the outcomes in terms of the response and survival rates between the two groups.RESULTS:Both the response rate and tumor suppression rate following HAIC were significantly superior in group A than in group B(response rate:48% vs 16%,P = 0.028,tumor suppression rate:87% vs 53%,P = 0.014).Furthermore,both the progression-free survival rate and survival time were significantly superior in group A than in group B(3-,6-,12-,and 24-mo = 83%,70%,29% and 20% vs 63%,42%,16% and 0%,respectively,P = 0.040,and 9.8 mo vs 6.2 mo,P = 0.040).A multivariate analysis(Cox proportional hazards regression model) showed that resistance to TACE was an independent predictor of poor survival(P = 0.007).CONCLUSION:HAIC administrating 5-FU was not effective against advanced HCC resistant to TACE.Other tools for treatment,i.e.,molecular-targeting agents may be considered for these cases. | Hiroyuki Kirikoshi Masato Yoneda Hironori Mawatari Koji Fujita Kento Imajo Shingo Kato Kaori Suzuki Noritoshi Kobayashi Kensuke Kubota Shin Maeda Atsushi Nakajima Satoru Saito | 2012 | World Journal of Gastroenterology2012，18，16： | 9 |
| 9 | Structure and function of ALG-2,a penta-EF-hand calcium-dependent adaptor protein显示文摘ALG-2(a gene product of PDCD6) is a 22-kD protein containing five serially repetitive EF-hand structures and belongs to the penta-EF-hand(PEF) family,including the subunits of typical calpains.ALG-2 is the most conserved protein among the PEF family members and its homologs are widely found in eukaryotes.X-ray crystal structures of various PEF proteins including ALG-2 have common features:presence of eightα-helices and dimer formation via paired EF5s that are positioned in anti-parallel orientation.ALG-2 forms a homodimer and a heterodimer with its closest paralog peflin.Like calmodulin,a well-known four-EF-hand protein,ALG-2 interacts with various proteins in a Ca2+-dependent fashion,but the binding motifs are completely different.With some exceptions,ALG-2-interacting proteins commonly contain Pro-rich regions,and ALG-2 recognizes at least two distinct Pro-containing motifs:PPYP(X) nYP(X,variable;n=4 in ALIX and PLSCR3) and PXPGF(represented by Sec31A) .A shorter alternatively spliced isoform,lacking two residues and designated ALG-2 GF122,does not bind ALIX but maintains binding capacity to Sec31A.X-ray crystal structural analyses have revealed that binding of calcium ions induces the configuration of the side chain of R125 so that it opens Pocket 1,which accepts PPYP,but Pocket 1 remains closed in the case of ALG-2 GF122.ALG-2 dimer has two ligand-binding sites,each in a monomer molecule,and appears to function as a Ca2+-dependent adaptor protein to either stabilize a preformed complex or to bridge two proteins on scaffolds in systems of the endosomal sorting complex required for transport(ESCRT) and ER-to-Golgi transport. | Masatoshi MAKI Hironori SUZUKI Hideki SHIBATA | 2011 | Science China(Life Sciences)2011，54，8： | 9 |
| 10 | Evolution of gastric surgery techniques and outcomes显示文摘Surgical management of gastric cancer improves survival.However,for some time,surgeons have had diverse opinions about the extent of gastrectomy.Researchers have conducted many clinical studies,making slow but steady progress in determining the optimal surgical approach.The extent of lymph node dissection has been one of the major issues in surgery for gastric cancer.Many trials demonstrated that D2 dissection resulted in greater morbidity and mortality than D1 dissection.However,long-term outcomes demonstrated that D2 dissection resulted in longer survival than D1 dissection.In 2004,the Japan Clinical Oncology Group reported a pivotal trial which was performed to determine whether para-aortic lymph node dissection combined with D2 dissection was superior to D2 dissection alone and found no benefit of the additional surgery.Gastrectomy with pancreatectomy,splenectomy,and bursectomy was initially recommended as part of the D2 dissection.Now,pancreas-preserving total gastrectomy with D2 dissection is standard,and ongoing trials are addressing the role of splenectomy.Furthermore,the feasibility and safety of laparoscopic gastrectomy are well established.Survival and quality of life are increasingly recognized as the most important endpoints.In this review,we present perspectives on surgical techniques and important trials of these techniques in gastric cancer patients. | Hironori Shiozaki Yusuke Shimodaira Elena Elimova Roopma Wadhwa Kazuki Sudo Kazuto Harada Jeannelyn S.Estrella Prajnan Das Brian Badgwell Jaffer A.Ajani | 2016 | Chinese Journal of Cancer2016，35，8： | 9 |

| 12 | Scattered and rapid intrahepatic recurrences after radio frequency ablation for hepatocellular carcinoma显示文摘AIM: To evaluate a series of patients with hepatocellular carcinoma (HCC) treated with several different protocols and devices.METHODS: We treated 138 patients [chronic hepatitis/liver cirrhosis (Child-Pugh A/B/C), 3/135 (107/25/3)]with two different devices and protocols: cool-tip needle [initial ablation at 60 W (standard method) (n=37)or at 40 W (modified method) (n = 28)] or; ablation with a LeVeen needle using a standard single-step, full expansion (single-step) method (n = 39) or a multi-step,incremental expansion (multi-step) method.RESULTS: Eleven patients experienced rapid and scattered recurrences 1 to 7 mo after the ablation. Nine patients were treated by the cool-tip original protocol (60 W) (9/37=24%) and the other two by the LeVeen single-step method (2/39=5%). The location of the recurrence was surrounding and limited to the site of ablation segment in three cases, and spread over one lobule or both lobules in the other eight cases. There was no recurrence in the patients treated with the modified cool-tip modified method (40 W) or the LeVeen multi-step method.CONCLUSION: There is a risk of rapid and scattered recurrence after RFA, especially when the standard cooltip procedure is used. Because such recurrence would worsen the prognosis, we recommend that modified protocols for the cool-tip and LeVeen needle methods should be used in clinical practice. | Kazuhiro Kotoh Munechika Enjoji Eiichirou Arimura Shusuke Morizono Motoyuki Kohjima Hironori Sakai Makoto Nakamuta | 2005 | World Journal of Gastroenterology2005，11，43： | 7 |

| 14 | Complete response to preoperative chemoradiotherapy in highly advanced gastric adenocarcinoma显示文摘This report presents a case of highly advanced gastric cancer that achieved a histologically complete response (CR) to preoperative chemoradiotherapy with S-1 plus low-dose Cisplatin. A 60-year-old male patient underwent FDG positron emission tomography (PET) during a routine health examination. The patient was found to have swollen paraaortic lymph nodes. Shortly thereafter, he was diagnosed with gastric carcinoma with a type 2 tumor in the antrum with paraaortic lymph node metastases based on FDG-PET, endoscopic examination and abdominal computed tomography. After the completion of chemoradiation therapy (CRT), the tumor and the paraaortic lymph node metastases disappeared. The patient underwent surgery 5 wk after the completion of CRT, including a subtotal gastrectomy with Rouxen-Y reconstruction, D3 lymph node dissection and a left adrenalectomy. No cancer cells were detected in the resected specimen either in the primary lesion or lymph nodes, thus confirming a pathologically CR to CRT (CR grade 3). The patient has been stable and well without any evidence of recurrence for 48 mo after surgery. Such a preoperative CRT regimen might therefore be very effective for treatment of some advanced gastric cancers. | Hironori Shigeoka Haruhiko Imamoto Yasumasa Nishimura Taro Shimono Hiroshi Furukawa Hiroshi Imamura Takushi Yasuda Hitoshi Shiozaki | 2010 | World Journal of Gastrointestinal Oncology2010，2，6： | 6 |
| 15 | Clinical outcomes of enteroscopy using the double-balloon method for strictures of the small intestine显示文摘AIM: To evaluate the clinical outcome of enteroscopy, using the double-balloon method, focusing on the involvement of neoplasms in strictures of the small intestine.METHODS: Enteroscopy, using the double-balloon method, was performed between December 1999 and December 2002 at Jichi Medical School Hospital, Japan and strictures of the small intestine were found in 17 out of 62 patients. These 17 consecutive patients were subjected to analysis.RESULTS: The double-balloon enteroscopy contributed to the diagnosis of small intestinal neoplasms found in 3out of 17 patients by direct observation of the strictures as well as biopsy sampling. Surgical procedures were chosen for these three patients, while balloon dilation was chosen for the strictures in four patients diagnosed with inflammation without involvement of neoplasm.CONCLUSION: Double-balloon enteroscopy is a useful method for the diagnosis and treatment of strictures in the small bowel. | Keijiro Sunada Hironori Yamamoto Hiroto Kita Tomonori Yano Hiroyuki Sato Yoshikazu Hayashi Tomohiko Miyata Yutaka Sekine Akiko Kuno Michiko Iwamoto Hirohide Ohnishi Kenichi Ido Kentaro Sugano | 2005 | World Journal of Gastroenterology2005，11，7： | 6 |
| 16 | Non-steroidal anti-inflammatory drug-induced small bowel injuries identified by double-balloon endoscopy显示文摘AIM: To clarify clinical features of the NSAID-induced small bowel lesions using a new method of endoscopy.METHODS: This is a retrospective study and we analyzed seven patients with small bowel lesions while taking NSAIDs among 61 patients who had undergone doubleballoon endoscopy because of gastro-intestinal bleeding or anemia between September 2000 and March 2004, at Jichi Medical School Hospital in Japan. Neither conventional EGD nor colonoscopy revealed any lesions of potential bleeding sources including ulcerations. Double-balloon endoscopy was carried out from oral approach in three patients, from anal approach in three patients, and from both approaches in one patient.RESULTS: Ulcers or erosions were observed in the ileum in six patients and in the jejunum in one patient, respectively.The ulcers were multiple in all the patients with different features from tiny punched out ulcers to deep ulcerations with oozing hemorrhage or scar. All the patients recovered uneventfully and had full resolution of symptoms after suspension of the drug.CONCLUSION: NSAIDs can induce injuries in the small bowel even in patients without any lesions in both the stomach and colon. | Yoshikazu Hayashi Hironori Yamamoto Hiroto Kita Keijiro Sunada Hiroyuki Sato Tomonori Yano Michiko Iwamoto Yutaka Sekine Tomohiko Miyata Akiko Kuno Takaaki Iwaki Yoshiyuki Kawamura Hironari Ajibe Kenichi Ido Kentaro Sugano | 2005 | World Journal of Gastroenterology2005，11，31： | 6 |
| 17 | MicroRNA-31 expression in colorectal serrated pathway progression显示文摘MicroRNAs have been increasingly recognized as useful biomarkers for colorectal cancers(CRC).We have recently observed that microRNA-31(miR-31)expression is associated with BRAF mutation and prognosis in CRC.Moreover,high miR-31 expression is frequently detected in sessile serrated adenomas compared with hyperplastic polyps(HPs).These results suggest that miR-31 may contribute to the progression of serrated lesions.At a follow-up colonoscopy,we observed the case of a 75-year-old man with a 7-mm flat-elevated lesion in the cecum and diagnosed the lesion as an early invasive carcinoma with serrated features.Tissue specimens were obtained from the representative areas to compare the molecular alterations in the carcinoma component with those in the HP component.Higher miR-31 expression was observed in the carcinoma component(57-fold increase)and the HP component(8-fold increase)compared with the paired normal mucosa,suggesting that miR-31 may be one of the key molecules in serrated pathway progression. | Hironori Aoki Katsuhiko Nosho Hisayoshi Igarashi Miki Ito Kei Mitsuhashi Takafumi Naito Eiichiro Yamamoto Tokuma Tanuma Masafumi Nomura Hiroyuki Maguchi Toshiya Shinohara Hiromu Suzuki Hiroyuki Yamamoto Yasuhisa Shinomura | 2014 | World Journal of Gastroenterology2014，20，34： | 5 |
| 18 | Nomograms for colorectal cancer:A systematic review显示文摘AIM: To assist in the selection of suitable nomograms for obtaining desired predictions in daily clinicalpractice.METHODS: We conducted electronic searches for journal articles on colorectal cancer(CRC)-associated nomograms using the search terms colon/rectal/colorectal/nomogram. Of 174 articles initially found, we retrieved 28 studies in which a nomogram for CRC was developed.RESULTS: We discuss the currently available CRCassociated nomograms, including those that predict the oncological prognosis, the short-term outcome of treatments, such as surgery or neoadjuvant chemoradiotherapy, and the future development of CRC. Developing nomograms always presents a dilemma. On the one hand, the desire to cover as wide a patient range as possible tends to produce nomograms that are too complex and yet have C-indexes that are not sufficiently high. Conversely, confining the target patients might impair the clinical applicability of constructed nomograms.CONCLUSION: The information provided in this review should be of use in selecting a nomogram suitable for obtaining desired predictions in daily clinical practice. | Kazushige Kawai Eiji Sunami Hironori Yamaguchi Soichiro Ishihara Shinsuke Kazama Hiroaki Nozawa Keisuke Hata Tomomichi Kiyomatsu Junichiro Tanaka Toshiaki Tanaka Takeshi Nishikawa Joji Kitayama Toshiaki Watanabe | 2015 | World Journal of Gastroenterology2015，21，41： | 5 |
| 19 | Lysophosphatidic acid transactivates both c-Met and epidermal growth factor receptor, and induces cyclooxygenase-2 expression in human colon cancer LoVo cells显示文摘AIM: To examine whether lysophosphatidic acid (LPA)induces phosphorylation of c-Met and epidermal growth factor receptor (EGFR), both of which have been proposed as prognostic markers of colorectal cancer, and whether LPA induces cyclooxygenase-2 (COX-2) expression in human colon cancer cells.METHODS: Using a human colon cancer cell line, LoVo cells, we performed immunoprecipitation analysis,followed by Western blot analysis. We also examined whether LPA induced COX-2 expression, by Western blot analysis.RESULTS: Immunoprecipitation analysis revealed that 10 μmol/L LPA induced tyrosine phosphorylation of c-Met and EGFR in LoVo cells within a few minutes. We found that c-Met tyrosine phosphorylation induced by LPA was not attenuated by pertussis toxin or a matrix metalloproteinase inhibitor, in marked contrast to the results for EGFR. In addition, 0.2-40 μmol/L LPA induced COX-2 expression in a dose-dependent manner.CONCLUSION: Our results suggest that LPA acts upstream of various receptor tyrosine kinases (RTKs) and COX-2,and thus may act as a potent stimulator of colorectal cancer. | Joji Kitayama Hironori Yamaguchi Hiroharu Yamashita Ken Mori Toshiaki Watanabe Hirokazu Nagawa | 2005 | World Journal of Gastroenterology2005，11，36： | 5 |
| 20 | Dysbiotic infection in the stomach显示文摘Microbiota in human alimentary tract plays important roles for homeostatic maintenance of the body. Compositional difference of gut microbiota is tightly associated with susceptibility of many diseases,including inflammatory diseases,obesity,diabetes mellitus,cancer,and atherosclerosis. 'Dysbiosis' refers to a state of imbalance among the colonies of microorganisms within the body,which brings abnormal increase of specific minor components and decrease in the normally dominant species. Since stomach secrets strong acid for its digestive role,this organ has long been thought a sterile organ. However,the discovery of Helicobacter pylori(H. pylori) has changed the concept. This bacterium has proven to cause gastritis,peptic ulcer,and gastric cancer. However,recent cross-sectional studies revealed that H. pylori carriers had a decreased risk of developing immunological diseases,such as asthma. H. pylori coinfection also suppresses inflammatory bowel diseases. This review describes human gastric microbiota by discussing its mutual interaction and pathogenic enrollment. Gastric 'dysbiosis' may affect host inflammatory response and play important role for gastric pathogenesis. We will topically discuss enrollment of dysbiosis for genesis of gastric cancer as well as for disruption of immunological homeostasis affecting oncogenic resistance. | Hisashi Iizasa Shyunji Ishihara Timmy Richardo Yuichi Kanehiro Hironori Yoshiyama | 2015 | World Journal of Gastroenterology2015，21，40： | 5 |
