| 1 | Nonalcoholic fatty liver disease is a novel predictor of cardiovascular disease显示文摘AIM:To clarify whether nonalcoholic fatty liver disease(NAFLD)increases the risk of cardiovascular disease.METHODS:We carried out a prospective observational study with a total of 1637 apparently healthy Japanese men and women who were recruited from a health check-up program.NAFLD was diagnosed by abdominal ultrasonography.The metabolic syndrome(MS)was defined according to the modified National Cholesterol Education Program(NCEP)ATP Ⅲ criteria.Five years after the baseline evaluations,the incidence of cardiovascular disease was assessed by a self-administered questionnaire.RESULTS:Among 1221 participants available for outcome analyses,the incidence of cardiovascular disease was higher in 231 subjects with NAFLD at baseline(5 coronary heart disease,6 ischemic stroke,and 1 cerebral hemorrhage)than 990 subjects without NAFLD(3 coronary heart disease,6 ischemic stroke,and 1 cerebral hemorrhage).Multivariate analyses indicated that NAFLD was a predictor of cardiovascular disease independent of conventional risk factors(odds ratio 4.12,95% CI,1.58 to 10.75,P = 0.004).MS was alsoindependently associated with cardiovascular events.But simultaneous inclusion of NAFLD and MS in a multivariate model revealed that NAFLD but not MS retained a statistically significant correlation with cardiovascular disease.CONCLUSION:Although both of them were predictors of cardiovascular disease,NAFLD but not MS retained a statistically significant correlation with cardiovascular disease in a multivariate model.NAFLD is a strong predictor of cardiovascular disease and may play a central role in the cardiovascular risk of MS. | Masahide Hamaguchi Takao Kojima Noriyuki Takeda Chisato Nagata Jun Takeda Hiroshi Sarui Yutaka Kawahito Naohisa Yoshida Atsushi Suetsugu Takahiro Kato Junichi Okuda Kazunori Ida Toshikazu Yoshikawa | 2007 | World Journal of Gastroenterology2007,13,10: | 55 |

| 3 | Clinical features of gastroduodenal injury associated with long-term low-dose aspirin therapy显示文摘Low-dose aspirin(LDA) is clinically used for the prevention of cardiovascular and cerebrovascular events with the advent of an aging society.On the other hand,a very low dose of aspirin(10 mg daily) decreases the gastric mucosal prostaglandin levels and causes significant gastric mucosal damage.The incidence of LDAinduced gastrointestinal mucosal injury and bleeding has increased.It has been noticed that the incidence of LDA-induced gastrointestinal hemorrhage has increased more than that of non-aspirin non-steroidal anti-inflammatory drug(NSAID)-induced lesions.The pathogenesis related to inhibition of cyclooxygenase(COX)-1 includes reduced mucosal flow,reduced mucus and bicarbonate secretion,and impaired platelet aggregation.The pathogenesis related to inhibition of COX-2 involves reduced angiogenesis and increased leukocyte adherence.The pathogenic mechanisms related to direct epithelial damage are acid back diffusion and impaired platelet aggregation.The factors associated with an increased risk of upper gastrointestinal(GI) complications in subjects taking LDA are aspirin dose,history of ulcer or upper GI bleeding,age > 70 years,concomitant use of non-aspirin NSAIDs including COX-2-selective NSAIDs,and Helicobacter pylori(H.pylori) infection.Moreover,no significant differences have been found between ulcer and non-ulcer groups in the frequency and severity of symptoms such as nausea,acid regurgitation,heartburn,and bloating.It has been shown that the ratios of ulcers located in the body,fundus and cardia are significantly higher in bleeding patients than the ratio of gastroduodenal ulcers in patients taking LDA.Proton pump inhibitors reduce the risk of developing gastric and duodenal ulcers.In contrast to NSAIDinduced gastrointestinal ulcers,a well-tolerated histamine H2-receptor antagonist is reportedly effective in prevention of LDA-induced gastrointestinal ulcers.The eradication of H.pylori is equivalent to treatment with omeprazole in preventing recurrent bleeding.Continuous aspirin therapy for patients with gastrointestinal bleeding may increase the risk of recurrent bleeding but potentially reduces the mortality rates,as stopping aspirin therapy is associated with higher mortality rates.It is very important to prevent LDA-induced gastroduodenal ulcer complications including bleeding,and every effort should be exercised to prevent the bleeding complications. | Junichi Iwamoto Yoshifumi Saito Akira Honda Yasushi Matsuzaki | 2013 | World Journal of Gastroenterology2013,19,11: | 29 |
| 4 | Glycer-AGEs-RAGE signaling enhances the angiogenic potential of hepatocellular carcinoma by upregulating VEGF expression显示文摘AIM:To investigate the effect of glyceraldehyde-derived advanced glycation end-products(Glycer-AGEs) on hepatocellular carcinoma(HCC)cells.METHODS:Two HCC cell lines(Hep3B and HepG2 cells)and human umbilical vein endothelial cells(HUVEC)were used.Cell viability was determined using the WST-8 assay.Western blotting,enzyme linked immunosorbent assay,and real-time reverse transcriptionpolymerase chain reactions were used to detect protein and mRNA.Angiogenesis was evaluated by assessing the proliferation,migration,and tube formation of HUVEC.RESULTS:The receptor for AGEs(RAGE)protein was detected in Hep3B and HepG2 cells.HepG2 cells werenot affected by the addition of Glycer-AGEs.GlycerAGEs markedly increased vascular endothelial growth factor(VEGF)mRNA and protein expression,which is one of the most potent angiogenic factors.Compared with the control unglycated bovine serum albumin(BSA) treatment,VEGF mRNA expression levels induced by the Glycer-AGEs treatment were 1.00±0.10 vs 1.92 ±0.09(P<0.01).Similarly,protein expression levels induced by the Glycer-AGEs treatment were 1.63±0.04 ng/mL vs 2.28±0.17 ng/mL for the 24 h treatment and 3.36±0.10 ng/mL vs 4.79±0.31 ng/mL for the 48 h treatment,respectively(P<0.01).Furthermore,compared with the effect of the control unglycated BSA-treated conditioned medium,the Glycer-AGEstreated conditioned medium significantly increased the proliferation,migration,and tube formation of HUVEC,with values of 122.4%±9.0%vs 144.5%±11.3%for cell viability,4.29±1.53 vs 6.78±1.84 for migration indices,and 71.0±7.5 vs 112.4±8.0 for the number of branching points,respectively(P<0.01).CONCLUSION:These results suggest that Glycer-AGEs-RAGE signaling enhances the angiogenic potential of HCC cells by upregulating VEGF expression. | Junichi Takino Shoichi Yamagishi Masayoshi Takeuchi | 2012 | World Journal of Gastroenterology2012,18,15: | 27 |
| 5 | Evaluation and treatment of malignant ascites secondary to gastric cancer显示文摘Malignant ascites affects approximately 10% of patients with gastric cancer(gC), and poses significant difficulties for both patients and clinicians. In addition to the dismal general condition of affected patients and the diversity of associated complications such as jaundice and ileus, problems in assessing scattered tumors have hampered the expansion of clinical trials for this condition. However, the accumulation of reported studies is starting to indicate that the weak response to treatment in g C patients with malignant ascites is more relevant to their poor prognosis rather than to the ascites volume at diagnosis. Therefore, precise assessment of initial state of ascites, repetitive evaluation of treatment efficacy, selection of suitable treatment, and swift transition to other treatment options as needed are paramount to maximizing patient benefit. Accurately determining ascites volume is the crucial first step in clinically treating a patient with malignant ascites. Ultrasonography is commonly used to identify the existence of ascites, and several methods have been proposed to estimate ascites volume. Reportedly, the sum of the depth of ascites at five points(named 'five-point method') on three panels of computed tomography images is well correlated to the actual ascites volume and/or abdominal girth. This method is already suited to repetitive assessment due to its convenience compared to the conventional volume rendering method. Meanwhile, a new concept, 'Clinical Benefit Response in g C(CBR-GC)', was recently introduced to measure the efficacy of chemotherapy for malignant ascites of g C. CBR-GC is a simple and reliable patient-oriented evaluation system based on changes in performance status and ascites, and is expected to become an important clinical endpoint in future clinical trials. The principal of treatment for g C patients with ascites is palliation and prevention of ascites-related symptoms. The treatment options are various, including a standard treatment based on the available guidelines, cytoreductive surgery with hyperthermic intraperitoneal chemotherapy(HIPEC), laparoscopic HIPEC alone, intravenous chemotherapy, intraperitoneal chemotherapy, and molecular targetingtherapy. Although each treatment option is valid,further research is imperative to establish the optima choice for each patient. | Hiromichi Maeda Michiya Kobayashi Junichi Sakamoto | 2015 | World Journal of Gastroenterology2015,21,39: | 23 |
| 6 | Cooperative function of antioxidant and redox systems against oxidative stress in male reproductive tissues显示文摘Reactive oxygen species (ROS) are produced under oxidative stress, such as high oxygen concentration and during the metabolic consumption of oxygen molecules. Male reproductive tissues appear to be continuously exposed to ROS produced by active metabolism. In addition, spermatozoa must pass through a high oxygen environ-ment during the mating process. Thus, to maintain viable reproductive ability, a protective mechanism against oxida-tive stress is of importance. Here, we overview our current understanding of the cooperative function of antioxidative and redox systems that are involved in male fertility. Superoxide dismutase and glutathione peroxidase are major enzymes that scavenge harmful ROS in male reproductive organs. In turn, glutathione and thioredoxin systems constitute the main redox systems that repair oxidized and damaged molecules and also play a role in regulating a variety of cellular functions. While glutathione functions as an antioxidant by donating electrons to glutathione peroxidase and thioredoxin donates electrons to peroxiredoxin as a counterpart of glutathione peroxidase. In addition,aldo-keto reductases, which detoxify carbonyl compounds produced by oxidative stress, are present at high levels in the epithelia of the genital tract and Sertoli cells of the testis. Since these systems are involved in cross-talk, a comprehensive understanding will be required to maintain the physiological functions of male reproductive system.( Asian J Andro12003 Sep; 5: 231-242) | Junichi Fujii Yoshihito Iuchi Shingo Matsuki Tatsuya Ishii | 2003 | Asian Journal of Andrology2003,5,3: | 19 |
| 7 | Predictive findings forHelicobacter pylori-uninfected, -infected and -eradicated gastric mucosa: Validation study显示文摘AIM:To validate the usefulness of screening endoscopy findings for predictingHelicobacter pylori (H. pylori) infection status. METHODS:H. pylori infection status was determined by histology, serology, and the urea breast test in 77 consecutive patients who underwent upper endoscopy. Based on the findings, patients were categorized as H. pylori -uninfected, -infected, or -eradicated cases. Using six photos of certain sites in the stomach per case, we determined the presence or absence of the following endoscopic findings:regular arrangement of collecting venules (RAC), linear erythema, hemorrhage, fundic gland polyp (FGP), atrophic change, rugal hyperplasia, edema, spotty erythema, exudate, xanthoma, and mottled patchy erythema (MPE). The diagnostic odds ratio (DOR) and inter-observer agreement (Kappa value) for these 11 endoscopic findings used in the determination of H. pylori infection status were calculated. RESULTS:Of the 77 patients [32 men and 45 women; mean age (SD), 39.7 (13.4) years] assessed, 28 were H. pylori uninfected, 28 were infected, and 21 were eradicated. DOR values were significantly high (< 0.05) for the following H. pylori cases:uninfected cases with RAC (11.5), linear erythema (24.5), hemorrhage (4.1), and FGP (34.5); for infected cases with atrophic change (8.67), rugal hyperplasia (15.8), edema (14.2), spotty erythema (11.5), and exudate (3.52); and for eradicated cases with atrophic change (32.4) and MPE (103.0). Kappa values were excellent for FGP (0.93), good for RAC (0.63), hemorrhage (0.79), atrophic change (0.74), and MPE (0.75), moderate for linear erythema (0.51), rugal hyperplasia (0.49), edema (0.58), spotty erythema (0.47), and exudate (0.46), and poor for xanthoma (0.19). CONCLUSION:The endoscopic findings of RAC, hemorrhage, FGP, atrophic change, and MPE will be useful for predicting H. pylori infection status. | Kazuhiro Watanabe Naoyoshi Nagata Ryo Nakashima Etsuko Furuhata Takuro Shimbo Masao Kobayakawa Toshiyuki Sakurai Koh Imbe Ryota Niikura Chizu Yokoi Junichi Akiyama Naomi Uemura | 2013 | World Journal of Gastroenterology2013,19,27: | 17 |
| 8 | Mutual interaction between oxidative stress and endoplasmic reticulum stress in the pathogenesis of diseases specifically focusing on non-alcoholic fatty liver disease显示文摘Reactive oxygen species(ROS) are produced during normal physiologic processes with the consumption of oxygen. While ROS play signaling roles, when they are produced in excess beyond normal antioxidative capacity this can cause pathogenic damage to cells. The majority of such oxidation occurs in polyunsaturated fatty acids and sulfhydryl group in proteins, resulting in lipid peroxidation and protein misfolding, respectively. The accumulation of misfolded proteins in the endoplasmic reticulum(ER) is enhanced under conditions of oxidative stress and results in ER stress, which, together, leads to the malfunction of cellular homeostasis. Multiple types of defensive machinery are activated in unfolded protein response under ER stress to resolve this unfavorable situation. ER stress triggers the malfunction of protein secretion and is associated with a variety of pathogenic conditions including defective insulin secretion from pancreatic β-cells and accelerated lipid droplet formation in hepatocytes. Herein we use nonalcoholic fatty liver disease(NAFLD) as an illustration of such pathological liver conditions that result from ER stress in association with oxidative stress. Protecting the ER by eliminating excessive ROS viathe administration of antioxidants or by enhancing lipidmetabolizing capacity via the activation of peroxisome proliferator-activated receptors represent promising therapeutics for NAFLD. | Junichi Fujii Takujiro Homma Sho Kobayashi Han Geuk Seo | 2018 | World Journal of Biological Chemistry2018,9,1: | 17 |

| 10 | Investigation and prediction of enteral nutrition problems after percutaneous endoscopic gastrostomy显示文摘AIM:To investigate and predict enteral nutrition problems after percutaneous endoscopic gastrostomy (PEG). METHODS:We retrospectively analyzed data for 252 out of 285 patients who underwent PEG at our hospital from 1999 to 2008.Enteral nutrition problems after PEG were defined as:(1)patients who required ≥1 mo after surgery to switch to complete enteral nutrition,or who required additional parenteral alimentation continuously;or(2)patients who abandoned switching to enteral nutrition using the gastrostoma and employed other nutritional methods. We attempted to identify the predictors of problem cases by using a logistic regression analysis that examined the patients’backgrounds and the specific causes that led to their problems. RESULTS:Mean age of the patients was 75 years,and in general,their body weight was low and their overall condition was markedly poor.Blood testing revealed that patients tended to be anemic and malnourished.A total of 44 patients(17.5%)were diagnosed as having enteral nutrition problems after PEG.Major causes ofthe problems included pneumonia,acute enterocolitis (often Clostridium difficile-related),paralytic ileus and biliary tract infection.A multivariate analysis identified the following independent predictors for problem cases:(1)enteral nutrition before gastrectomy(a risk reduction factor);(2)presence of esophageal hiatal hernia;(3)past history of paralytic ileus;and(4) presence of chronic renal dysfunction. CONCLUSION:Enteral nutrition problems after PEG occurred at a comparatively high rate.Patient background analysis elucidated four predictive factors for the problem cases. | Shiro Yokohama Masaru Aoshima Yukiomi Nakade Junya Shindo Junichi Maruyama Masashi Yoneda | 2009 | World Journal of Gastroenterology2009,15,11: | 14 |
| 11 | Ghrelin and gastric acid secretion显示文摘Ghrelin, a novel growth hormone-releasing peptide, was originally isolated from rat and human stomach. Ghrelin has been known to increase the secretion of growth hormone (GH), food intake, and body weight gain when administered peripherally or centrally. Ghrelin is also known to stimulate the gastric motility and the secretion of gastric acid. In the previous studies, the action of ghrelin on acid secretion was shown to be as strong as that of histamine and gastrin in in-vivo experiment. In the studies, the mechanism for the action of ghrelin was also investigated. It was shown that vagotomy completely inhibited the action of ghrelin on the secretion of gastric acid suggesting that vagal nerve is involved in the mechanism for the action of ghrelin on acid secretion. As famotidine did not inhibit ghrelin-in-duced acid secretion in the study by Masuda et al, they concluded that histamine was not involved in the action of ghrelin on acid secretion. However, we have shown that famotidine completely inhibited ghrelin-induced acid secretion and histidine decarboxylase (HDC) mRNA was increased in gastric mucosa by ghrelin injection which is inhibited by vagotomy Our results indicate that histamine is involved in the action of ghrelin on acid secretion. Furthermore synergistic action of gastrin and ghrelin on gastric acid secretion was shown. Although gastrin has important roles in postprandial secretion of gastric acid, ghrelin may be related to acid secretion during fasting period or at night. However, further studies are needed to elucidate the physiological role of ghrelin in acid secretion. | Koji Yakabi Junichi Kawashima Shingo Kato | 2008 | World Journal of Gastroenterology2008,14,41: | 13 |
| 12 | Diagnostic efficacy of gadoxetic acid-enhanced MRI for hepatocellular carcinoma and dysplastic nodule显示文摘AIM:To evaluate the relationship between the signal intensity of hepatobiliary phase images on gadoxetic acid-enhanced magnetic resonance imaging(MRI)and histological grade.METHODS:Fifty-nine patients with 82 hepatocellular lesions were evaluated retrospectively.Hepatobiliary phase images on gadoxetic acid-enhanced MRI were classified into 3 groups:low,iso or high.Angiographyassisted computed tomography(CT)findings were also classified into 3 groups:CT during arterial portography,and CT hepatic arteriography:A:iso,iso or low;B:slightly low,iso or low;;and C:low,high.We correlated angiography-assisted CT,hepatobiliary phase findings during gadoxetic acid-enhanced MRI and histological grades.Furthermore,correlations between MRI findings and histological grade for each hemodynamic pattern were performed.Correlations among radiologicaland pathological findings were statistically evaluated using the chi-square test and Fisher's exact test.RESULTS:There was a significant correlation between histological grade and hemodynamic pattern(P<0.05).There was a significant correlation between histological grade and signal intensity in the hepatobiliary phase(P<0.05)in group A lesions.There was no significant correlation between histological grade and signal intensity in the hepatobiliary phase in group B or C lesions(P>0.05).CONCLUSION:Signal intensity in the hepatobiliary phase correlated with histological grade in the lesions that maintained portal blood flow,but did not correlate in lesions that showed decreased or defective portal blood flow. | Kazuhiro Saito Ryota Nishio Toru Saguchi Soichi Akata Koichi Tokuuye Fuminori Moriyasu Katsutoshi Sugimoto Junichi Taira Toshitaka Nagao | 2011 | World Journal of Gastroenterology2011,17,30: | 12 |

| 15 | Boron neutron capture therapy for vulvar melanoma and genital extramammary Paget’s disease with curative responses显示文摘Background:Although the most commonly recommended treatment for melanoma and extramammary Paget’s disease(EMPD)of the genital region is wide surgical excision of the lesion,the procedure is highly invasive and can lead to functional and sexual problems.Alternative treatments have been used for local control when wide local exci-sion was not feasible.Here,we describe four patients with genital malignancies who were treated with boron neutron capture therapy(BNCT).Methods:The four patients included one patient with vulvar melanoma(VM)and three with genital EMPD.They underwent BNCT at the Kyoto University Research Reactor between 2005 and 2014 using para-boronophenylalanine as the boron delivery agent.They were irradiated with an epithermal neutron beam between the curative tumor dose and the tolerable skin/mucosal doses.Results:All patients showed similar tumor and normal tissue responses following BNCT and achieved complete responses within 6 months.The most severe normal tissue response was moderate skin erosion during the first 2 months,which diminished gradually thereafter.Dysuria or contact pain persisted for 2 months and resolved com-pletely by 4 months.Conclusions:Treating VM and EMPD with BNCT resulted in complete local tumor control.Based on our clinical expe-rience,we conclude that BNCT is a promising treatment for primary VM and EMPD of the genital region. | Junichi Hiratsuka Nobuhiko Kamitani Ryo Tanaka Eisaku Yoden Ryuji Tokiya Minoru Suzuki Rolf F.Barth Koji Ono | 2018 | Cancer Communications2018,38,1: | 10 |
| 16 | Small-bowel mucosal injuries in low-dose aspirin users with obscure gastrointestinal bleeding显示文摘AIM: To investigate the clinical differences between small intestinal injuries in low-dose aspirin(LDA) users and in non-steroidal anti-inflammatory drug(NSAID) users who were examined by capsule endoscopy(CE) for obscure gastrointestinal bleeding(OGIB). METHODS: A total of 181 patients who underwent CE for OGIB were included in this study. Based on clinical records, laboratory data such as hemoglobin levels, major symptoms, underlying diseases, the types and duration of LDA and NSAID use, and endoscopic characteristics of CE were reviewed.RESULTS: Out of a total of 45 cases of erosive lesions, 27 cases were taking LDA or NSAIDs(7 were on NSAIDs, 9 were on LDA alone, 9 were on LDA and thienopyridine, and 2 were on LDA and warfarin).The prevalence of ulcers or erosion during chronic use of LDA, LDA and the anti-platelet drug thienopyridine (clopidogrel or ticlopidine), and NSAIDs were 64.3%, 80.0%, and 75.0%, respectively. Erosive lesions were observed predominantly in chronic LDA users, while ulcerative lesions were detected mainly in NSAID users. However, concomitant use of thienopyridine such as clopidogrel with LDA increased the proportion of ulcers. The erosive lesions were located in the whole of the small intestine(jejunum and ileum), whereas ulcerative lesions were mainly observed in the ileum(P < 0.05). CONCLUSION: Our CE findings indicate that chronic LDA users and NSAID users show different types and locations of small-bowel mucosal injuries. The concomitant use of anti-platelet drugs with LDA tends to exacerbate the injuries from LDA-type to NSAID-type injuries. | Junichi Iwamoto Yuji Mizokami Yoshifumi Saito Koichi Shimokobe Akira Honda Tadashi Ikegami Yasushi Matsuzaki | 2014 | World Journal of Gastroenterology2014,20,36: | 9 |
| 17 | Crosstalk between angiogenesis, cytokeratin-18, and insulin resistance in the progression of non-alcoholic steatohepatitis显示文摘AIM: To elucidate the possible crosstalk between angiogenesis, cytokeratin-18 (CK-18), and insulin resistance (IR) especially in patients with non-alcoholic steatohepatitis (NASH).METHODS: Twenty-eight patients with NASH and 11 with simple fatty liver disease (FL) were enrolled in this study and underwent clinicopathological examination. The measures of angiogenesis, CK-18, and IR employed were CD34-immunopositive vessels, CK-18immunopositive cells, and homeostasis model assessment of IR (HOMA-IR), respectively. The correlations of these factors with NASH were elucidated.RESULTS: Significant development of hepatic neovascularization was observed only in NASH, whereas almost no neovascularization could be observed in FL and healthy liver. The degree of angiogenesis was almost parallel to liver fibrosis development, and both parameters were positively correlated. Similarly, CK-18expression and HOMA-R were signifi cantly increased in NASH as compared with FL and healthy liver. Furthermore, CK-18 and HOMA-IR were also positively correlated with the degree of neovascularization. CONCLUSION: These results indicate that the crosstalk between angiogenesis, CK-18, and IR may play an important role in the onset and progression of NASH. | Mitsuteru Kitade Hitoshi Yoshiji Ryuichi Noguchi Yasuhide Ikenaka Kosuke Kaji Yusaku Shirai Masaharu Yamazaki Masahito Uemura Junichi Yamao Masao Fujimoto Akira Mitoro Masahisa Toyohara Masayoshi Sawai Motoyuki Yoshida Chie Morioka Tatsuhiro Tsujimoto Hideto Kawaratani Hiroshi Fukui | 2009 | World Journal of Gastroenterology2009,15,41: | 9 |
| 18 | Quality of life in gastric cancer显示文摘AIM: To summarize the empirical research on assessing quality of life (QOL) in patients with gastric carcinoma. METHODS: Literature searches were conducted in MedLine from 1966 to February 2004. RESULTS: Twenty-six studies were identified. QOL was used as an outcome measure in virtually all identified studies, such as those examining the effects of gastric cancer and various medical or surgical treatments in the patients. QOL was assessed mainly with generic measures; the social dimensions of QOL were largely neglected. The lack of gastric cancer-specific QOL measures hampers QOL research up to now. The gastric cancer-specific EORTCQLQ-STO22 and the FACT-Ga are important additions to the arsenal of disease-specific QOL measures. In most of the studies, the label QOL is used for questionnaires, which only assess symptoms or performance status, or are physician-reported rather than patient-reported outcomes. CONCLUSION: QOL in patients with gastric cancer deserves more systematic studies, especially as one of the outcome measures in randomized clinical trials. Results of studies that include QOL in patients with gastric cancer should be applied in clinical care, which aims at improving QOL of these patients. | Ad A.Kaptein Satoshi Morita Junichi Sakamoto | 2005 | World Journal of Gastroenterology2005,11,21: | 8 |
| 19 | Oxidative stress as a potential causal factor for autoimmune hemolytic anemia and systemic lupus erythematosus显示文摘The kidneys and the blood system mutually exert influence in maintaining homeostasis in the body. Because the kidneys control erythropoiesis by producing erythropoietin and by supporting hematopoiesis, anemia is associated with kidney diseases. Anemia is the most prevalent genetic disorder, and it is caused by a deficiency of glucose 6-phosphate dehydrogenase(G6PD), for which sulfhydryl oxidation due to an insufficient supply of NADPH is a likely direct cause. Elevated reactive oxygen species(ROS) result in the sulfhydryl oxidation and hence are another potential cause for anemia. ROS are elevated in red blood cells(RBCs) under superoxide dismutase(SOD1) deficiency in C57BL/6 mice. SOD1 deficient mice exhibit characteristics similar to autoimmune hemolytic anemia(AIHA) and systemic lupus erythematosus(SLE) at the gerontic stage. An examination of AIHA-prone New Zealand Black(NZB) mice, which have normal SOD1 and G6 PD genes, indicated that ROS levels in RBCs are originally high and further elevated during aging. Transgenic overexpression of human SOD1 in erythroid cells effectively suppresses ROS elevation and ameliorates AIHA symptoms such as elevated anti-RBC antibodies and premature death in NZB mice. These results support the hypothesis that names oxidative stress as a risk factor for AIHA and other autoimmune diseases such as SLE. Herein we discuss the association between oxidative stress and SLE pathogenesis based mainly on the genetic and phenotypic characteristics of NZB and New Zealand white mice and provide insight into the mechanism of SLE pathogenesis. | Junichi Fujii Toshihiro Kurahashi Tasuku Konno Takujiro Homma Yoshihito Iuchi | 2015 | World Journal of Nephrology2015,4,2: | 7 |
| 20 | 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 |
