| 3 | Gastric adenocarcinoma of fundic gland type:Endoscopicand clinicopathological features显示文摘Gastric adenocarcinoma of fundic gland type(GA-FG) with chief cell differentiation was recently proposed as an extremely rare type of gastric adenocarcinoma. Here, we report 4 cases of GA-FG with chief cell differentiation. Endoscopic features included a submucosal tumor shape or a flat shape, whitish discoloration and dilated vessels on the surface. The tumors were located in the upper or middle third of the stomach. All cases were preoperatively diagnosed as GA-FG by biopsy, and endoscopic submucosal dissection was performed. Resected specimens revealed well-differentiated adenocarcinomas resembling chief cells. Tumor cells were diffusely positive for pepsinogen-Ⅰ, but partially positive for H+/K+-ATPase in scattered locations around the tumor margin. Despite the presence of minimal invasion of the carcinoma into the submucosal layer, which was observed in two cases, neither lymphatic nor venous invasion was detected in any of the cases. Finally, all cases showed less aggressive clinical behavior with low grade malignancy. | Gen Tohda Takeshi Osawa Yasuyuki Asada Masaki Dochin Shintarou Terahata | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，4： | 26 |
| 4 | Criteria 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 | 2013 | World Journal of Gastroenterology2013，19，35： | 24 |
| 5 | Useful detection of CD147 (EMMPRIN) for pathological diagnosis of early hepatocellular carcinoma in needle biopsy samples显示文摘AIM:To make clear whether CD147 (EMMPRIN) expression in pathological tumor samples with a fine-needle aspiration biopsy is useful for pathological diagnosis of early hepatocellular carcinoma (HCC). METHODS:Twenty-two patients (15 men and 7 women; median age 68 years,range 56-81 years) underwent a liver tissue biopsy in order to make a diagnosis of HCC. Paraffin-embedded liver biopsy tissue samples from 22 patients were stained with anti-CD147 antibody,murine monoclonal antibody 12C3 (MAb12C3) for immunohistochemical analysis. An immunohistochemical analysis of CD147 was performed and the degree of staining compared between tumor and non-tumor tissue. In addition,the degree of staining within tumor tissue was compared according to a number of clinicopathological variables. RESULTS:The degree of staining of CD147 was significantly higher in tumor tissues than non-tumor tissues,even in tumors less than 15 mm in diameter.The expression of this protein was significantly elevated in HCC tissue specimens from patients with a low value of serum AST and γ-GTP. | Satoshi Mamori Keisuke Nagatsuma Tomokazu Matsuura Kiyoshi Ohkawa Hiroshi Hano Masaharu Fukunaga Masato Matsushima Yoshifumi Masui Nao Fushiya Hiroshi Onoda Yasuyuki Searashi Ichiro Takagi Hisao Tajiri | 2007 | World Journal of Gastroenterology2007，13，21： | 20 |
| 6 | Glucose metabolism in gastric cancer:The cutting-edge显示文摘Glucose metabolism in gastric cancer cells differs from that of normal epithelial cells. Upregulated aerobic glycolysis(Warburg effect) in gastric cancer meeting the demands of cell proliferation is associated with genetic mutations, epigenetic modification and proteomic alteration. Understanding the mechanisms of aerobic glycolysis may contribute to our knowledge of gastric carcinogenesis. Metabolomic studies offer novel, convenient and practical tools in the search for new biomarkers for early detection, diagnosis, prognosis, and chemosensitivity prediction of gastric cancer. Interfering with the process of glycolysis in cancer cells may provide a new and promising therapeutic strategy for gastric cancer. In this article, we present a brief review of recent studies of glucose metabolism in gastric cancer, with primary focus on the clinical applications of new biomarkers and their potential therapeutic role in gastric cancer. | Lian-Wen Yuan Hiroharu Yamashita Yasuyuki Seto | 2016 | World Journal of Gastroenterology2016，22，6： | 18 |
| 7 | 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 |
| 8 | Safety and effectiveness of propofol sedation during and after outpatient colonoscopy显示文摘AIM:To study the safety and effectiveness of propofol sedation for outpatient colonoscopy.METHODS:Propofol was given by bolus injection with an age-adjusted standard protocol consisting of 60 mg for patients < 70 years old,40 mg for patients age 70-89 years,and 20 mg for those ≥ 90 years,and additional injections of 20 mg propofol were given up to a maximum of 200 mg.The principal parameters were the occurrence of adverse events within 24 h after colonoscopy and overall satisfaction for this procedure.Secondary parameters included successful procedure,respiratory depression,and other complications.RESULTS:Consecutive patients were entered prospectively and all 2101 entered successfully completed outpatient colonoscopy.The mean dose of propofol used was 96.4 mg(range 40-200 mg).Younger patients required higher doses of propofol than older patients(20-40 years vs ≥ 61 years:115.3 ± 32 mg vs 89.7 ± 21 mg,P < 0.001).Transient supplemental oxygen supply was needed by five patients(0.2%);no other complications occurred.The questionnaires were completed by 1820(87%) of 2101 patients and most rated their overall satisfaction as excellent(80%) or good(17%).The majority(65%) of patients drove home or to their office after their colonoscopy.Most(99%) were willing to repeat the same procedure.No incidents occurred within 24 h after colonoscopy.CONCLUSION:Propofol sedation using a dose < 200 mg proved both safe and practical for outpatient colonoscopy. | Akira Horiuchi Yoshiko Nakayama Masashi Kajiyama Naoyuki Kato Tetsuya Kamijima Yasuyuki Ichise Naoki Tanaka | 2012 | World Journal of Gastroenterology2012，18，26： | 15 |

| 10 | A rare case of hyaline-type Castleman disease in the liver显示文摘Castleman disease often develops in the neck, mediastinum and pulmonary hilum. Its onset in the peritoneal cavity is very rare. The patient, a woman in her 70s, was referred to our department for a detailed examination of an abdominal mass. On abdominal ultrasonography, computed tomography scan, magnetic resonance imaging and positron emission tomography, a mass approximately 15 mm in diameter was noted in the hepatic S6. We attempted radical treatment and conducted a laparoscope-assisted right lobectomy. On the basis of histopathological findings, the patient was diagnosed as having hyaline type Castleman disease in the liver, a very rare condition. | Hisaaki Miyoshi Shima Mimura Takako Nomura Joji Tani Asahiro Morishita Hideki Kobara Hirohito Mori Hirohito Yoneyama Akihiro Deguchi Takashi Himoto Naoki Yamamoto Keiichi Okano Yasuyuki Suzuki Tsutomu Masaki | 2013 | World Journal of Hepatology2013，5，7： | 14 |

| 13 | ^(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 |
| 14 | Eight-year survival after advanced gastric cancer treated with S-1 followed by surgery显示文摘We report a case of advanced gastric cancer, with cervical, axillary, and abdominal paraaortic lymph node metastases, that was successfully treated with chemotherapy and surgery. The disease was initially considered unresectable, and the patient was treated with orally administered S-1. Chemotherapy was effective, and all lymph node metastases disappeared after 6 courses. After 27 mo of chemotherapy, the patient underwent curative surgery, with subtotal gastrectomy and lymph node dissection. Histopathological examination revealed many viable poorly differentiated adenocarcinoma cells in the stomach, but no cancer cells in the lymph nodes. The patient is alive, without recurrence, 8 years later. This, therefore, is a case report of an 8-year survivor of advanced gastric cancer with distant lymph node metastasis. | Susumu Hijioka Keisho Chin Yasuyuki Seto Noriko Yamamoto Kiyohiko Hatake | 2010 | World Journal of Gastroenterology2010，16，22： | 10 |
| 15 | Numerical analysis of cavitation cloud shedding in a submerged water jet显示文摘Focused on the unsteady behavior of high-speed water jets with intensive cavitation a numerical analysis is performed by applying a practical compressible mixture flow bubble cavitation model with a simplified estimation of bubble radius. The mean flow of two-phase mixture is calculated by unsteady Reynolds averaged Navier-Stokes(URANS) for compressible flow and the intensity of cavitation in a local field is evaluated by the volume fraction of gas bubbles whose radius is estimated with a simplified RayleighPlesset equation according to pressure variation of the mean flow field. High-speed submerged water jet issuing from a sheathed sharp-edge orifice nozzle is treated. The periodically shedding of cavitation clouds is captured in a certain reliability compared to experiment data of visualization observation and the capability to capture the unsteadily shedding of cavitation clouds is demonstrated. The results demonstrate that cavitation takes place near the entrance of nozzle throat and cavitation cloud expands consequentially while flowing downstream. Developed bubble clouds break up near the nozzle exit and shed downstream periodically along the shear layer. Under the effect of cavitation bubbles the decay of core velocity is delayed compared to the case of no-cavitation jet. | Guoyi PENG 杨从新 Yasuyuki OGUMA Seiji SHIMIZU | 2016 | Journal of Hydrodynamics2016，28，6： | 10 |
| 16 | Temperature evolution from the δ ^(18)O record of Hani peat, Northeast China, in the last 14000 years显示文摘From the last deglaciation to the Holocene, the Greenland Ice Core (GISP2) δ 18O records as well as the records of ice-rafted debris on the surface of the North Atlantic have revealed a succession of sudden cooling events on the centennial to millennial scales. However, the temperature proxy records are rarely studied systematically and directly to ensure that this air temperature cooling pattern simultaneously existed in the East Asian Region, in addition to the repeated pattern occurring in the Greater Atlantic Region. A peat cellulose δ 18O temperature proxy record proximately existing for 14000 years was picked up from the Hani peat in Jilin Province, China. It suggests by comparison that the sudden cooling events, such as the Older Dryas, Inter-Allerφd, Younger Dryas, and nine ice-rafted debris events of the North Atlantic, are almost entirely reiterated in the temperature signals of Hani peat cellulose δ 18O. These cooling events show that the repeatedly occurring temperature cooling pattern not only appeared in the North Atlantic Region in the high latitudes, but also in the Northwest Pacific Region in the middle latitudes. The climate change events marking the start of the Holocene Epoch, the Holocene Megathermal, the '8.2 kyr' event, the '4.2 kyr' event, the Medieval Warm Period, and the Little Ice Age are further discussed. The sensitivity response of Hani peat cellulose δ 18O to the land surface temperature and the reason for the age accuracy of peat cellulose 14C are also discussed based on the characteristics of the peat bog environment. | Shibata YASUYUKI | 2009 | Science China Earth Sciences2009，52，7： | 9 |
| 17 | Serum anti-Helicobacter pylori antibody titer and its association with gastric nodularity,atrophy,and age:A cross-sectional study显示文摘AIM To clarify the role of serum anti-Helicobacter pylori(H. pylori) antibody titers in gastric cancer.METHODS In this cross-sectional study, the effect of patients' baseline characteristics and endoscopic findings on their serum antibody titers were assessed. We evaluated consecutive patients who underwent esophagogastroduodenoscopy and their first evaluation for H. pylori infection using a serum antibody test. We excluded patients with a history of eradication therapy. The participants were divided into four groups according to their E-plate serum antibody titer. Patients with serum antibody titers < 3, 3-9.9, 10-49.9, and ≥ 50 U/m L were classified into groups A, B, C, and D, respectively. RESULTS In total, 874 participants were analyzed with 70%, 16%, 8.7%, and 5.1% of them in the groups A, B, C, and D, respectively. Patients in group C were older than patients in groups A and B. Gastric open-type atrophy, intestinal metaplasia, enlarged folds, diffuse redness, and duodenal ulcers were associated with a high titer. Regular arrangements of collecting venules, fundic gland polyps, superficial gastritis, and gastroesophageal reflux disease were related to a low titer. Multivariate analysis revealed that nodularity(P = 0.0094), atrophy(P = 0.0076), and age 40-59 years(vs age ≥ 60 years, P = 0.0090) were correlated with a high serum antibody titer in H. pylori-infected patients. Intestinal metaplasia and atrophy were related to age ≥ 60 years in group C and D.CONCLUSION Serum antibody titer changes with age, reflects gastric mucosal inflammation, and is useful in predicting the risk of gastric cancer. | Osamu Toyoshima Toshihiro Nishizawa Kosuke Sakitani Tadahiro Yamakawa Yoshiyuki Takahashi Nobutake Yamamichi Keisuke Hata Yasuyuki Seto Kazuhiko Koike Hidenobu Watanabe Hidekazu Suzuki | 2018 | World Journal of Gastroenterology2018，24，35： | 9 |
| 18 | Prognostic factors of T4 gastric cancer patients undergoing potentially curative resection显示文摘AIM:To investigate the prognostic factors of T4 gastric cancer patients without distant metastasis who could undergo potentially curative resection. METHODS:We retrospectively analyzed the clinical data of 71 consecutive patients diagnosed with T4 gastric cancer and who underwent curative gastrectomy at our institutions.The clinicopathological factors that could be associated with overall survival were evaluated.The cumulative survival was determined by the Kaplan-Meier method,and univariate comparisons between the groups were performed using the log-rank test.Multivariate analysis was performed using the Cox proportional hazard model and a step-wise procedure. RESULTS:The study patients comprised 53 men (74.6%)and 18 women(25.4%)aged 39-89 years (mean,68.9 years).Nineteen patients(26.8%)had postoperative morbidity:pancreatic fistula developed in 6 patients(8.5%)and was the most frequent complication,followed by anastomosis stricture in 5 patients (7.0%).During the follow-up period,28 patients(39.4%)died because of gastric cancer recurrence,and 3(4.2%) died because of another disease or accident.For all patients,the estimated overall survival was 34.1%at 5 years.Univariate analyses identified the following statistically significant prognostic factors in T4 gastric cancer patients who underwent potentially curative resection: peritoneal washing cytology(P<0.01),number of metastatic lymph nodes(P<0.05),and venous invasion(P <0.05).In multivariate analyses,only peritoneal washing cytology was identified as an independent prognostic factor(HR=3.62,95%CI=1.37-9.57)for longterm survival. CONCLUSION:Positive peritoneal washing cytology was the only independent poor prognostic factor for T4 gastric cancer patients who could be treated with potentially curative resection. | Naoto Fukuda Yasuyuki Sugiyama Joji Wada | 2011 | World Journal of Gastroenterology2011，17，9： | 8 |
| 19 | Usefulness of urinary trypsinogen-2 and trypsinogen activation peptide in acute pancreatitis:A multicenter study in Japan显示文摘BACKGROUND Rapid urinary trypsinogen-2 dipstick test and levels of urinary trypsinogen-2 and trypsinogen activation peptide(TAP) concentration have been reported as prognostic markers for the diagnosis of acute pancreatitis.AIM To reconfirm the validity of all these markers in the diagnosis of acute pancreatitis by undertaking a multi-center study in Japan.METHODS Patients with acute abdominal pain were recruited from 17 medical institutions in Japan from April 2009 to December 2012. Urinary and serum samples were collected twice, at enrollment and on the following day for measuring target markers. The diagnosis and severity assessment of acute pancreatitis were assessed based on prognostic factors and computed tomography(CT) Grade of the Japanese Ministry of Health, Labour, and Welfare criteria.RESULTS A total of 94 patients were enrolled during the study period. The trypsinogen-2 dipstick test was positive in 57 of 78 patients with acute pancreatitis(sensitivity,73.1%) and in 6 of 16 patients with abdominal pain but without any evidence of acute pancreatitis(specificity, 62.5%). The area under the curve(AUC) score of urinary trypsinogen-2 according to prognostic factors was 0.704, which was highest in all parameter. The AUC scores of urinary trypsinogen-2 and TAP according to CT Grade were 0.701 and 0.692, respectively, which shows higher than other pancreatic enzymes. The levels of urinary trypsinogen-2 and TAP were significantly higher in patients with extended extra-pancreatic inflammation as evaluated by CT Grade.CONCLUSION We reconfirmed urinary trypsinogen-2 dipstick test is useful as a marker for the diagnosis of acute pancreatitis. Urinary trypsinogen-2 and TAP may be considered as useful markers to determine extra-pancreatic inflammation in acute pancreatitis. | Hiroaki Yasuda Keisho Kataoka Yoshifumi Takeyama Kazunori Takeda Tetsuhide Ito Toshihiko Mayumi Shuji Isaji Tetsuya Mine Motoji Kitagawa Seiki Kiriyama Junichi Sakagami Atsushi Masamune Kazuo Inui Kenji Hirano Ryukichi Akashi Masamichi Yokoe Yoshio Sogame Kazuichi Okazaki Chie Morioka Yasuyuki Kihara Shigeyuki Kawa Masao Tanaka Akira Andoh Wataru Kimura Isao Nishimori Junji Furuse Isao Yokota Tooru Shimosegawa | 2019 | World Journal of Gastroenterology2019，25，1： | 7 |
| 20 | Rectal perforations and fistulae secondary to a glycerin enema:Closure by over-the-scope-clip显示文摘Rectal perforations due to glycerin enemas(GE) typically occur when the patient is in a seated or lordotic standing position.Once the perforation occurs and peritonitis results,death is usually inevitable.We describe two cases of rectal perforation and fistula caused by a GE.An 88-year-old woman presented with a large rectal perforation and a fistula just after receiving a GE.Her case was further complicated by an abscess in the right rectal wall.The second patient was a 78-year-old woman who suffered from a rectovesical fistula after a GE.In both cases,we performed direct endoscopic abscess lavage with a saline solution and closed the fistula using an over-the-scope-clip(OTSC) procedure.These procedures resulted in dramatic improvement in both patients.Direct endoscopic lavage and OTSC closure are very useful for pararectal abscess lavage and fistula closure,respectively,in elderly patients who are in poor general condition.Our two cases are the first reports of the successful endoscopic closure of fistulae using double OTSCs after endoscopic lavage of the debris and an abscess of the rectum secondary to a GE. | Hirohito Mori Hideki Kobara Shintaro Fujihara Noriko Nishiyama Mitsuyoshi Kobayashi Tsutomu Masaki Kunihiko Izuishi Yasuyuki Suzuki | 2012 | World Journal of Gastroenterology2012，18，24： | 6 |
