| 2 | Clinical significance of type V_I pit pattern subclassification in determining the depth of invasion of colorectal neoplasms显示文摘AIM: To clarify whether subclassification of the type VI pit pattern on the basis of magnifying colonoscopy findings is useful in determining the type and depth of invasion of colorectal neoplasms.METHODS: We retrospectively analyzed 272 colorectal neoplasms (117 dysplasias and 155 submucosal invasive carcinomas; 228 patients) with a type V pit pattern [type VI, n = 202; type VN, n = 70 (Kudo and Tsuruta classification system)]. We divided lesions with a type VI pit pattern into two subclasses, mildly irregular lesions and severely irregular lesions, according to the prominent and detailed magnifying colonoscopy findings. We examined the relation between these two subclasses and histology/invasion depth.RESULTS: One hundred and four lesions (51.5%) were judged to be mildly irregular, and 98 lesions (48.5%) were judged to be severely irregular. Ninety-seven (93.3%) mildly irregular lesions showed dysplasias or submucosal invasion of less than 1000 μm (SM < 1000 μm). Fifty-five (56.1%) severely irregular lesions showed submucosal invasion equal to or deeper than 1000 μm (SM ≥ 1000 μm). Mild irregularity was found significantly more often in dysplasias or lesions with SM < 1000 μm than in lesions with SM ≥ 1000 μm (P < 0.01).CONCLUSION: Subclassification of the type VI pit pattern is useful for identifying dysplasias or lesions with SM < 1000 μm. | Hiroyuki Kanao Shinji Tanaka Shiro Oka Iwao Kaneko Shigeto Yoshida Koji Arihiro Masaharu Yoshihara Kazuaki Chayama | 2008 | World Journal of Gastroenterology2008，14，2： | 15 |
| 3 | Effects of zincate treatment on adhesion of electroless Ni-P coating onto various aluminum alloys显示文摘The effects of alloying elements on zincate treatment and adhesion of electroless Ni-P coating onto various aluminum alloy substrates were examined.Surface morphology of zinc deposits in the 1st zincate treatment and its adhesion were changed depending on the alloying element.The zinc deposits in the 2nd zincate treatment became thinly uniform,and the adhesion between aluminum alloy substrate and Ni-P coating was improved irrespective of the alloying element.XPS analysis revealed the existence of zinc on the surface of each aluminum alloy substrate after the pickling in 5% nitric acid.This zinc on the surface should be an important factor influencing the morphology of zinc deposit at the 2nd zincate treatment and its adhesion. | Makoto HINO Koji MURAKAMI Yutaka MITO OKA Ken MURAOKA Teruto KANADANI | 2009 | 中国有色金属学会会刊:英文版2009，19，4： | 14 |
| 4 | Immunohistochemical molecular markers as predictors of curability of endoscopically resected submucosal colorectal cancer显示文摘AIM: To clarify the usefulness of immunohistochemical molecular markers in predicting lymph node metastasis of submucosal colorectal cancer. METHODS: We examined microvessel density, lymphatic vessel density, the Ki-67 labeling index, expression of MUC1 and Matrix metalloproteinase-7 (MMP-7) in tumor cells, and expression of cathepsin D in stromal cells at the invasive front by immunostaining of samples resected from 214 patients with submucosal colorectal cancer. Pathologic features were assessed on hematoxylin-eosin- stained samples. We evaluated the relations between clinicopathologic/immunohistochemical features and lymph node metastasis. RESULTS: Lesions of the superficial type, with an unfavorable histologic grade, budding, lymphatic involvement, high microvessel density (≥ 40), high lymphatic vessel density (≥ 9), high Ki-67 labeling index (≥ 42), and positivity of MUC1, cathepsin D, and MMP-7 showed a significantly high incidence of lymph node metastasis. Multivariate analysis revealed that high microvessel density, unfavorable histologic grade, cathepsin D positivity, high lymphatic vessel density, superficial type, budding, and MUC1 positivity were independent risk factors for lymph node metastasis.A combined examination with four independent immunohistochemical markers (microvessel density, cathepsin D, lymphatic vessel density, and MUC1) revealed that all lesions that were negative for all markers or positive for only one marker were negative for lymph node metastasis. CONCLUSION: Analysis of a combination of immuno- histochemical molecular markers in endoscopically resected specimens of submucosal colorectal cancer allows prediction of curability regardless of the pathologic features visible of hematoxylin-eosin-stained sections. | Iwao Kaneko Shinji Tanaka Shiro Oka Shigeto Yoshida Toru Hiyama Koji Arihiro Fumio Shimamoto Kazuaki Chayama | 2007 | World Journal of Gastroenterology2007，13，28： | 12 |
| 5 | Novel risk markers for gastric cancer screening: Present status and future prospects显示文摘Initial identification of populations at high risk of gastric cancer (GC) is important for endoscopic screening of GC. As serum pepsinogen (PG) test-positive subjects with progression of chronic atrophic gastritis (CAG) show a high likelihood of future cancer development, this population warrants careful follow-up observation as a high-risk GC group. By combining the PG test with Helicobacter pylori (HP) antibody titers, the HP-related chronic gastritis stage can be classified, thus identifying not only a GC high-risk group but also a low-risk group. Among PG test-negative patients without CAG, those with high serum PG Ⅱ levels and HP antibody titers are thought to have severe gastric mucosal inflammation and the risk of diffuse-type GC is also high. Meanwhile, in gastric mucosae obtained by endoscopic biopsy, HP infection induces aberrant DNA methylation in CpG islands in multiple gene regions and the extent of methylation clearly correlates with GC risk. By quantifying aberrant DNA methylation in suitable gene markers, we can determine the extent of the epigenetic field for cancerization. These novel concepts and risk markers will have many clinical applications in gastrointestinal endoscopy, including more efficient endoscopic GC screening and a strategic approach to metachronous multiple GCs after endoscopic treatment. | Shotaro Enomoto Takao Maekita Hiroshi Ohata Kimihiko Yanaoka Masashi Oka Masao Ichinose | 2010 | World Journal of Gastrointestinal Endoscopy2010，2，12： | 10 |
| 6 | BRIEF ARTICLE New reduced volume preparation regimen in colon capsule endoscopy显示文摘AIM:To evaluate the effectiveness of our proposed bowel preparation method for colon capsule endoscopy.METHODS:A pilot,multicenter,randomized controlled trial compared our proposed 'reduced volume method'(group A) with the 'conventional volume method'(group B) preparation regimens.Group A did not drink polyethylene glycol electrolyte lavage solution(PEGELS) the day before the capsule procedure,while group B drank 2 L.During the procedure day,groups A and B drank 2 L and 1 L of PEG-ELS,respectively,and swallowed the colon capsule(PillCam COLON capsule).Two hours later the first booster of 100 g magnesium citrate mixed with 900 mL water was administered to both groups,and the second booster was administered six hours post capsule ingestion as long as the capsule had not been excreted by that time.Capsule videos were reviewed for grading of cleansing level,RESULTS:Sixty-four subjects were enrolled,with results from 60 analyzed.Groups A and B included 31 and 29 subjects,respectively.Twenty-nine(94%) subjects in group A and 25(86%) subjects in group B had adequate bowel preparation(ns).Twenty-two(71%) of the 31 subjects in group A excreted the capsule within its battery life compared to 16(55%) of the 29 subjects in group B(ns).Of the remaining 22 subjects whose capsules were not excreted within the battery life,all of the capsules reached the left side colon before they stopped functioning.A single adverse event was reported in one subject who had mild symptoms of nausea and vomiting one hour after starting to drink PEG-ELS,due to ingesting the PEG-ELS faster than recommended.CONCLUSION:Our proposed reduced volume bowel preparation method for colon capsule without PEG-ELS during the days before the procedure was as effective as the conventional volume method. | Yasuo Kakugawa Yutaka Saito Shoichi Saito Kenji Watanabe Naoki Ohmiya Mitsuyuki Murano Shiro Oka Tetsuo Arakawa Hidemi Goto Kazuhide Higuchi Shinji Tanaka Hideki Ishikawa Hisao Tajiri | 2012 | World Journal of Gastroenterology2012，18，17： | 8 |
| 7 | Successful initial ablation therapy contributes to survival in patients with hepatocellular carcinoma显示文摘AIM: To evaluate the outcome predictors of percu- taneous ablation therapy in patients with unresectable hepatocellular carcinoma (HCC), especially to identify whether the initial treatment response contributes to the survival of the patients. METHODS: The study cohort included 153 patients with single (102) and two or three (51) HCC nodules 5 cm or less in maximum diameter. As an initial treatment, 110 patients received radiofrequency ablation and 43 patients received percutaneous ethanol injection. RESULTS: The Kaplan-Meier estimates of overall 3- and 5-year survival rates were 75% and 59%, respectively. The log-rank test revealed statistically significant differences in the overall survivals according to Child- Pugh class (P = 0.0275), tumor size (P = 0.0130), serum albumin level (P = 0.0060), serum protein induced by vitamin K absence or antagonist Ⅱ level (P = 0.0486), and initial treatment response (P = 0.0130). The independent predictors of survival were serum albumin level (risk ratio, 3.216; 95% CI, 1.407-7.353; P = 0.0056) and initial treatment response (risk ratio, 2.474; 95% CI, 1.076-5.692; P = 0.0330) based on the Cox proportional hazards regression models. The patients had a serum albumin level 3.5 g/dL and the 3- and 5-year survival rates of 86% and 82%. CONCLUSION: In HCC patients treated with percutaneous ablation therapy, serum albumin level and initial treatment response are the independent outcome predictors. | Manabu Morimoto Kazushi Numata Kazuya Sugimori Kazuhito Shirato Atsushi Kokawa Hiroyuki Oka Kingo Hirasawa Ryonho Koh Hiromi Nihommatsu Katsuaki Tanaka | 2007 | World Journal of Gastroenterology2007，13，7： | 8 |
| 8 | Comparison of PPIs and H_2-receptor antagonists plus prokinetics for dysmotility-like dyspepsia显示文摘AIM:To compare efficacy of proton pump inhibitors(PPIs)with H2-receptor antagonists(H2RAs)plus prokinetics(Proks)for dysmotility-like symptoms in functional dyspepsia(FD).METHODS:Subjects were randomized to receive openlabel treatment with either rabeprazole 10 mg od(n= 57)or famotidine 10 mg bid plus mosapride 5 mg tid(n=57)for 4 wk.The primary efficacy endpoint was change(%)from baseline in total dysmotility-like dyspepsia symptom score.The secondary efficacy endpoint was patient satisfaction with treatment.RESULTS:The improvement in dysmotility-like dyspep-sia symptom score on day 28 was significantly greater in the rabeprazole group(22.5%±29.2%of baseline) than the famotidine+mosapride group(53.2%± 58.6%of baseline,P<0.0001).The superior benefit of rabeprazole treatment after 28 d was consistent regardless of Helicobacter pylori status.Significantly more subjects in the rabeprazole group were satisfied or very satisfied with treatment on day 28 than in the famotidine+mosapride group(87.7%vs 59.6%,P= 0.0012).Rabeprazole therapy was the only significant predictor of treatment response(P<0.0001),defined as a total symptom score improvement≥50%.CONCLUSION:PPI monotherapy improves dysmotility-like symptoms significantly better than H2RAs plus Proks,and should be the treatment of first choice for Japanese FD. | Masahiro Sakaguchi Miyuki Takao Yasuo Ohyama Hiroshi Oka Hiroshi Yamashita Takumi Fukuchi Kiyoshi Ashida Masahiro Murotani Masuyo Murotani Kazuo Majima Hiroshi Morikawa Takashi Hashimoto Keisuke Kiyota Hirohiko Esaki Kanji Amemoto Gouhei Isowa Fumiyuki Takao | 2012 | World Journal of Gastroenterology2012，18，13： | 8 |

| 10 | Effect of herbal medicine Juzentaihoto on hepatic and intestinal heat shock gene expression requires intestinal microflora in mouse显示文摘AIM: To evaluate the role of intestinal microflora in the effects of multi-herbal medicine on gene expression in the gut and liver. METHODS: The multi-herbal medicine Juzentaihoto (JTX) was administered to five germ-free mice and regular mice for 2 wk. Among the results of the comprehensive gene chip analysis of the intestine and liver, we featured heat shock proteins (HSPs) 70 and 105 because their gene expression changed only in the presence of microflora. Real-time RT-PCR was performed to confirm the expression levels of these HSP genes. To determine whether JTX acts directly on the HSP genes, sodium arsenite (SA) was used to induce the heat shock proteins directly. To examine the change of the intestinal microflora with administration of JTX, the terminal restriction fragment polymorphism (T-RFLP) method was used. To identify the changed bacteria, DNA sequencing was performed. RESULTS: Heat shock protein gene expression,documented by gene chip and real-time RT-PCR, changed with the administration of JTX in the regular mice but not in the germ-free mice. JTX did not suppress the direct induction of the HSPs by SA. T-RFLP suggested that JTX decreased unculturable bacteria and increased Lactobacillus johnsoni. These data suggested that JTX changed the intestinal microflora which, in turn, changed HSP gene expression. CONCLUSION: Intestinal microflora affects multi-herbal product JTX on the gene expression in the gut and liver. | Miho Kato Atsushi Ishige Naoko Anjiki Masahiro Yamamoto Yoshifumi Irie Mitsue Taniyama Ryoko Kibe Junichiro Oka Yoshimi Benno Kenji Watanabe | 2007 | World Journal of Gastroenterology2007，13，16： | 5 |

| 15 | Serum testosterone and prostate-specific antigen levels are major risk factors for prostatic volume increase among benign prostatic hyperplasia patients显示文摘Objective:Benign prostatic hyperplasia(BPH)is one of the most common diseases found among elderly men.Even though multiple risk factors of BPH have been identified in the past,the risk factors which have a direct impact on prostate volume have not been identified.In this study,we aim to determine the most significant contributing risk factors to prostate volume enlargement by analyzing possible associated risk factors previously studied.Methods:This is a quantitative study with an analytical observational design,performed using a retrospective cohort approach.Total sampling was performed on 83 patients who underwent transurethral resection of the prostate(TURP)in Sanglah General Hospital from January to February 2019.Bivariate analysis is performed to examine each variable's association with prostate volume followed by a multivariate analysis.All variables were reassessed with path analysis to measure the direct effects,indirect effects,and total effects on prostate volume.Results:Bivariate analysis shows that serum testosterone(R=0.208;p=0.059)and prostate-specific antigen(PSA)level(R=0.626;p=0.001)have a significant association with prostate volume.Multivariate analysis shows that serum PSA(B=1.4;p=0.001;95%confidence interval[95%CI]=1.039-1.770)and testosterone(B=0.024;p=0.005;95%CI=0.008-0.041)levels are significant among all the analyzed risk factors.There is a significant and strong effect of PSA to prostate volume(c=0.636;p=0.001)whereas testosterone has a significant albeit weak effect to prostate volume(c=0.246;p=0.009)based on the total effect of the path analysis.Conclusion:Serum testosterone and PSA levels are significantly associated with prostatic volume increase among BPH patients. | Gede Wirya Kusuma Duarsa Yudit Anastasia Sari Anak Agung Gde Oka Kadek Budi Santosa I Wayan Yudiana Pande Made Wisnu Tirtayasa Ida Bagus Putra Pramana Yudhistira Pradnyan Kloping | 2021 | Asian Journal of Urology2021，8，3： | 3 |
| 16 | Diagnostic value of antigenemia assay for cytomegalovirus gastrointestinal disease in immunocompromised patients显示文摘AIM:To investigate the utility of the cytomegalovirus(CMV)antigenemia assay for the diagnosis of CMV gastrointestinal disease(GID). METHODS:One hundred and thirty immunocompromised patients were enrolled in this study.Patients with a history of anti-CMV treatment and who had not undergone examination using the antigenemia assay were excluded.CMV-GID was defined as the detection of large cells with intranuclear inclusions alone or associated with granular cytoplasmic inclusions by biopsy.Biopsy sections were stained with hematoxylin and eosin and immunohistochemically stained with anti-CMV.We evaluated the association between CMV-GID and patient characteristics(symptoms,underlying disease,medication,leukocyte counts,and antigenemia assay).All patients were checked with an human immunodeficiency virus(HIV)antibody test before endoscopic examination.White blood cell(WBC)counts were obtained from medical records within 1 wk of endoscopy.Leukopenia was defined as a total WBC count<5000 cells/mm 3 . For HIV patients,we also checked CD4+counts from medical records. RESULTS:A total of 99 patients were retrospectively selected for analysis.Of the immunocompromised patients,19 had malignant disease,18 had autoimmune disease,19 had disorders of biochemical homeostasis, three had undergone transplantation,and 45 had HIV infection.A total of 50 patients had received immunosuppressive therapy.No patients had inflammatory bowel disease.Fifty-five patients were diagnosed as having CMV-GID.Univariate analysis indicated an association between HIV infection,leukopenia,and positive antigenemia and CMV-GID(P<0.05).Multivariate analysis using logistic regression revealed that HIV infection and positive antigenemia were the only independent factors related to CMV-GID(P<0.01).The sensitivity,specificity,positive predictive value,and negative predictive value of antigenemia for CMV-GID were 65.4%,93.6%, 91.9%,and 71.0%,respectively.In a subgroup analy-sis,patients with leukopenia displayed low sensitivity and high specificity.Minimal differences in accuracy were seen among patients with or without leukopenia. HIV-infected patients displayed low sensitivity and high specificity.Accuracy barely differed between HIV-positive and-negative patients.In HIV-infected patients, CD4 count<50 cells/μL resulted in low sensitivity and high specificity.Differences in accuracy among patients were minor,regardless of CD4 count.In patients who had undergone both quantitative real-time polymerase chain reaction(PCR)and antigenemia assay,real-time PCR was slightly more accurate in terms of sensitivity than the antigenemia assay;however,this difference was not statistically significant(P=0.312). CONCLUSION:If the antigenemia test is positive,endoscopic lesions are acceptable for the diagnosis of CMVGID without biopsy.The accuracy is not affected by HIV infection and leukopenia.Either PCR or the antigenemia assay are valid. | Naoyoshi Nagata Masao Kobayakawa Takuro Shimbo Kazufusa Hoshimoto Tomoyuki Yada Takuji Gotoda Junichi Akiyama Shinichi Oka Naomi Uemura | 2011 | World Journal of Gastroenterology2011，17，9： | 3 |
| 17 | Laparoscopic right hemicolectomy for ascending colon cancer with persistent mesocolon显示文摘Persistent ascending or descending mesocolon is an embryological anomaly that occurs during the final process of intestinal development in organogenesis.Specifically,the primitive dorsal mesocolon fails to fuse with the parietal peritoneum in the fifth month of gestation.Herein,we describe a case of ascending colon cancer with persistent ascending and descending mesocolon treated by laparoscopic right hemicolectomy.Preoperative computed tomography imaging of the abdomen demonstrated that the descending colon shifted at the midline of the abdomen and the sigmoid colon was located under the ascending colon.The detailed preoperative imaging examination revealed malpositioning of the large intestine and aided in the procedural planning.Because persistent mesocolon may result in the formation of abnormal adhesions,an accurate preoperative diagnosis is essential.We propose that it is important to consider this anomaly when making the preoperative imaging diagnosis to ensure a safe operation. | Atsushi Tsuruta Akimasa Kawai Yasuo Oka Hideo Okumura Hideo Matsumoto Toshihiro Hirai Masafumi Nakamura | 2014 | World Journal of Gastroenterology2014，20，18： | 3 |
| 18 | Walking-friendly built environments and objectively measured physical function in older adults显示文摘Background:Few studies have examined the associations between urban design attributes and older adults’physical function.Especially,it is not well known how built-environment attributes may influence physical function in Asian cities.The aim of this study was to examine associations between objectively measured environmental attributes of walkability and objectively assessed physical function in a sample of Japanese older adults.Methods:Cross-sectional data collected in 2013 from 314 older residents(aged 65-84 years)living in Japan were used.Physical function was estimated from objectively measured upper-and lower-body function,mobility,and balance by a trained research team member.A comprehensive list of built-environment attributes,including population density,availability of destinations,intersection density,and distance to the nearest public transport station,were objectively calculated.Walk Score as a composite measure of neighborhood walkability was also obtained.Results:Among men,higher population density,availability of destinations,and intersection density were significantly associated with better physical function performance(1-legged stance with eyes open).Higher Walk Score was also marginally associated with better physical function performance(1-legged stance with eyes open).None of the environmental attributes were associated with physical function in elderly women.Conclusion:Our findings indicate that environmental attributes of walkability are associated with the physical function of elderly men in the context of Asia.Walking-friendly neighborhoods can not only promote older adults’active behaviors but can also support their physical function. | Mohammad Javad Koohsari Gavin R.McCormack Tomoki Nakaya Ai Shibata Kaori Ishii Akitomo Yasunaga Yung Liao Koichiro Oka | 2020 | Journal of Sport and Health Science2020，9，6： | 3 |

| 20 | Endoscopic appearance of AIDS-related gastrointestinal lymphoma with c-MYC rearrangements: Case report and literature review显示文摘Acquired immune deficiency syndrome (AIDS)-related lymphoma (ARL) remains the main cause of AIDS-related deaths in the highly active anti-retroviral therapy (HAART) era. Recently, rearrangement of MYC is associated with poor prognosis in patients with diffuse large B-cell lymphoma. Here, we report a rare case of gastrointestinal (GI)-ARL with MYC rearrangements and coinfected with Epstein-Barr virus (EBV) infection presenting with various endoscopic findings. A 38-yearold homosexual man who presented with anemia and was diagnosed with an human immunodeficiency virus infection for the first time. GI endoscopy revealed multiple dish-like lesions, ulcerations, bloody spots, nodular masses with active bleeding in the stomach, erythematous flat lesions in the duodenum, and multiple nodular masses in the colon and rectum. Magnified endoscopy with narrow band imaging showed a honeycomb-like pattern without irregular microvessels in the dish-like lesions of the stomach. Biopsy specimens from the stomach, duodenum, colon, and rectum revealed diffuse large B-cell lymphoma concomitant with EBV infection that was detected by high tissue EBV-polymerase chain reaction levels and Epstein-Barr virus small RNAs in situ hybridization. Fluorescence in situ hybridization analysis revealed a fusion between the immunoglobulin heavy chain (IgH) and c-MYC genes, but not between the IgH and BCL2 loci. After 1-mo of treatment with HAART and R-CHOP, endoscopic appearance improved remarkably, and the histological features of the biopsy specimens revealed no evidence of lymphoma. However, he died from multiple organ failure on the 139 th day after diagnosis. The cause of his poor outcome may be related to MYC rearrangement. The GI tract involvement in ARL is rarely reported, and its endoscopic findings are various and may be different from those in non-AIDS GI lymphoma; thus, we also conducted a literature review of GI-ARL cases. | Shohei Tanaka Naoyoshi Nagata Sohtaro Mine Toru Igari Taiichiro Kobayashi Jun Sugihara Haruhito Honda Katsuji Teruya Yoshimi Kikuchi Shinichi Oka Naomi Uemura | 2013 | World Journal of Gastroenterology2013，19，29： | 3 |
