| 1 | Continuous regional arterial infusion therapy with gabexate mesilate for severe acute pancreatitis显示文摘AIM: To evaluate the effi cacy of continuous regional arterial infusion therapy (CRAI) with gabexate mesilate and antibiotics for severe acute pancreatitis (SAP). METHODS: We conducted a prospective study on patients who developed SAP with or without CRAI. Out of 18 patients fulf illed clinical diagnostic criteria for SAP in Japan, 9 patients underwent CRAI, while 9 patients underwent conventional systemic protease inhibitor and antibiotics therapy (non-CRAI). CRAI was initiated within 72 h of the onset of pancreatitis. Gabexate mesilate (2400 mg/d) was continuously administered for 3 to 5 d. The clinical outcome including serum infl ammation-related parameters were examined. RESULTS: The duration of abdominal pain in the CRAI group was 1.9 ± 0.26 d, whereas that in the non-CRAI group was 4.3 ± 0.50. The duration of SIRS in the CRAI group was 2.2 ± 0.22 d, whereas that in the non- CRAI group was 3.2 ± 0.28. Abdominal pain and SIRS disappeared signifi cantly in a short period of time after the initiation of CRAI using gabexate mesilate. The average length of hospitalization signifi cantly differed between the CRAI and non-CRAI groups, 53.3 ± 7.9 d and 87.4 ± 13.9 d, respectively. During the first two weeks, levels of serum CRP and the IL6/IL10 ratio in the CRAI group tended to have a rapid decrease compared to those in the non-CRAI group. CONCLUSION: The present results suggest that CRAI using gabexate mesilate was effective against SAP. | Yoshifumi Ino Yoshiyuki Arita Tetsuro Akashi Toshinari Kimura Hisato Igarashi Takamasa Oono Masayuki Furukawa Ken Kawabe Keiichiro Ogoshi Jiro Ouchi Toshihiko Miyahara Ryoichi Takayanagi Tetsuhide Ito | 2008 | World Journal of Gastroenterology2008，14，41： | 20 |

| 3 | Herbal cardiotonic pills prevent gut ischemia/reperfusion-induced hepatic microvascular dysfunction in rats fed ethanol chronically显示文摘AIM: Cardiotonic Pill (CP), an oral herbal medicine that includes Danshen (Salviae Miltiorrhizae), Panax notoginseny and Dyroblanops aromatica gaertn, has been clinically used for vascular diseases such as occlusive vasculitis, coronary diseases, atherosclerosis, and cerebral infarction. The main component, SaMae Miltiorrhizae, has been reported to prevent cerebral and intestinal reperfusion injury. However, little is known about the effect of CP on hepatic microcirculation.Thus, this study aimed to determine whether CP could affect hepatic microvascular dysfunction elicited by gut ischemia/reperfusion (I/R) in rats fed ethanol chronically.METHODS: Male Wistar rats were pair-fed with a liquid diet containing ethanol or isocaloric control diet for 6 wk. After laparotomy, one lobe of the liver was examined through an inverted intravital microscope. The rats were exposed to 30 rain of gut ischemia followed by 60 rain of reperfusion.Rhodamine-6G-labeled leukocytes in the sinusoids were observed 90 rain after the onset of superior mesenteric artery ocdusion. Plasma tumor necrosis factor (TNF)-α and endotoxin levels were measured 1 h after the onset of reperfusion.Plasma alanine aminotransferase (ALT) activities were measured 6 h after the onset of reperfusion. In another set of experiments, CP (0.8 g/kg, intragastrically) was administered 1 and 24 h before the onset of ischemia.RESULTS: In control rats, gut I/R elicited increases in the number of stationary leukocytes, and plasma TNF-α and endotoxin levels and plasma ALT activities. These changes were mitigated by pretreatment with CP. In ethanol-fed rats,the gut I/R-induced increases in the number of stationary leukooltes, plasma endotoxin levels and ALT activities were enhanced. Pretreat^nent with CP attenuated the enhancement of gut I/R-induced responses by chronic ethanol consumption.CONCLUSION: These results suggest that CP prevents the gut I/R-induced hepatic microvascular dysfunction and hepatocellular injury. A reduction of inflammatory responses such as TNF-α production via reduction of blood endotoxin levels appears to be involved in the mechanisms. Chronic ethanol consumption enhances gut I/R-induced hepatic microvascular and hepatocellular injury. CP also attenuates an enhancement of gut I/R-induced responses by chronic ethanol consumption via the reduction of blood endotoxin levels. | Yoshinori Horie Shuka Mori Masahiro Konishi Mikio Kajihara Takehiko Kaneko Yoshiyuki Yamagishi Shinzo Kato Hiromasa Ishii Toshifumi Hibi | 2005 | World Journal of Gastroenterology2005，11，4： | 13 |
| 4 | An updated review of gastric cancer in the next-generation sequencing era:Insights from bench to bedside and vice versa显示文摘Gastric cancer(GC)is one of the most common malignancies and remains the second leading cause of cancer-related death worldwide.There is an increasing understanding of the roles that genetic and epigenetic alterations play in GCs.Recent studies using nextgeneration sequencing(NGS)have revealed a number of potential cancer-driving genes in GC.Whole-exome sequencing of GC has identified recurrent somatic mutations in the chromatin remodeling gene ARID1A and alterations in the cell adhesion gene FAT4,a member of the cadherin gene family.Mutations in chromatin remodeling genes(ARID1A,MLL3 and MLL)have been found in 47%of GCs.Whole-genome sequencing and whole-transcriptome sequencing analyses have also discovered novel alterations in GC.Recent studies of cancer epigenetics have revealed widespread alterations in genes involved in the epigenetic machinery,such as DNA methylation,histone modifications,nucleosome positioning,noncoding RNAs and microRNAs.Recent advances in molecular research on GC have resulted in the introduction of new diagnostic and therapeutic strategies into clinical settings.The antihuman epidermal growth receptor 2(HER2)antibody trastuzumab has led to an era of personalized therapy in GC.In addition,ramucirumab,a monoclonal antibody targeting vascular endothelial growth factor receptor(VEGFR)-2,is the first biological treatment that showed survival benefits as a single-agent therapy in patients with advanced GC who progressed after firstline chemotherapy.Using NGS to systematically identify gene alterations in GC is a promising approach with remarkable potential for investigating the pathogenesis of GC and identifying novel therapeutic targets,as well as useful biomarkers.In this review,we will summarize the recent advances in the understanding of the molecular pathogenesis of GC,focusing on the potential use of these genetic and epigenetic alterations as diagnostic biomarkers and novel therapeutic targets. | Hiroyuki Yamamoto Yoshiyuki Watanabe Tadateru Maehata Ryo Morita Yoshihito Yoshida Ritsuko Oikawa Shinya Ishigooka Shun-ichiro Ozawa Yasumasa Matsuo Kosuke Hosoya Masaki Yamashita Hiroaki Taniguchi Katsuhiko Nosho Hiromu Suzuki Hiroshi Yasuda Yasuhisa Shinomura Fumio Itoh | 2014 | World Journal of Gastroenterology2014，20，14： | 12 |
| 5 | Prevention of esophageal strictures after endoscopic submucosal dissection显示文摘Endoscopic mucosal resection(EMR) and endoscopic submucosal dissection(ESD) have recently been accepted as less invasive methods for treating patients with early esophageal cancers such as squamous cell carcinoma and dysplasia of Barrett's esophagus.However,the large defects in the esophageal mucosa often cause severe esophageal strictures,which dramatically reduce the patient's quality of life.Although preventive endoscopic balloon dilatation can reduce dysphagia and the frequency of dilatation,other approaches are necessary to prevent esophageal strictures after ESD.This review describes several strategies for preventing esophageal strictures after ESD,with a particular focus on anti-inflammatory and tissue engineering approaches.The local injection of triamcinolone acetonide and other systemic steroid therapies are frequently used to prevent esophageal strictures after ESD.Tissue engineering approaches for preventing esophageal strictures have recently been applied in basic research studies.Scaffolds with temporary stents have been applied in five cases,and this technique has been shown to be safe and is anticipated to prevent esophageal strictures.Fabricated autologous oral mucosal epithelial cell sheets to cover the defective mucosa similarly to how commercially available skin products fabricated from epidermal cells are used for skin defects or in cases of intractable ulcers.Fabricated autologous oralmucosal-epithelial cell sheets have already been shown to be safe. | Shinichiro Kobayashi Nobuo Kanai Takeshi Ohki Ryo Takagi Naoyuki Yamaguchi Hajime Isomoto Yoshiyuki Kasai Takahiro Hosoi Kazuhiko Nakao Susumu Eguchi Masakazu Yamamoto Masayuki Yamato Teruo Okano | 2014 | World Journal of Gastroenterology2014，20，41： | 12 |
| 6 | Diagnostic evaluation of acute pancreatitis in two patients with hypertriglyceridemia显示文摘We present two diagnostically challenging cases of acute pancreatitis with hypertriglyceridemia accompanied with chylomicronemia caused with a deficiency of lipoprotein lipase and with the presence of type V hyperlipidemia.Both cases suffered from acute abdomen following the ingestion of fatty food and revealed the increase in parameters of inflammation without significant elevation of serum amylase levels. The imaging examination of ultrasonography could not detect significant findings of acute pancreatitis and a computer tomography scan eventually confirmed the findings of acute pancreatitis. Both cases responded to a low fat diet and administration of a cholecystokinin receptor antagonist, exhibiting a relief of abdominal symptoms. As in the present cases with acute abdomen following the ingestion of fatty food, the identification of serum hypertriglyceridemia and an abdominal computer tomography scan might be useful in establishing the diagnosis of acute pancreatitis and in developing the therapeutic regimen, when hypertriglyceridemia interferes with the evaluation of pancreatic enzyme activities and ultrasound examination provides poor pancreatic visualization. | Yoshifumi Okura KozoHayashi TetsujiShingu GoroKajiyama Yoshiyuki Nakashima Keijiro Saku | 2004 | World Journal of Gastroenterology2004，10，24： | 12 |
| 7 | Real-time in situ three-dimensional integral videography and surgical navigation using augmented reality: a pilot study显示文摘To evaluate the feasibility and accuracy of a three-dimensional augmented reality system incorporating integral videography for imaging oral and maxillofacial regions, based on preoperative computed tomography data. Three-dimensional surface models of the jawbones, based on the computed tomography data, were used to create the integral videography images of a subject's maxillofacial area. The three-dimensional augmented reality system (integral videography display, computed tomography, a position tracker and a computer) was used to generate a three-dimensional overlay that was projected on the surgical site via a half-silvered mirror. Thereafter, a feasibility study was performed on a volunteer. The accuracy of this system was verified on a solid model while simulating bone resection. Positional registration was attained by identifying and tracking the patient/surgical instrument's position. Thus, integral videography images of jawbones, teeth and the surgical tool were superimposed in the correct position. Stereoscopic images viewed from various angles were accurately displayed. Change in the viewing angle did not negatively affect the surgeon's ability to simultaneously observe the three-dimensional images and the patient, without special glasses. The difference in three-dimensional position of each measuring point on the solid model and augmented reality navigation was almost negligible (<1 mm); this indicates that the system was highly accurate. This augmented reality system was highly accurate and effective for surgical navigation and for overlaying a three-dimensional computed tomography image on a patient's surgical area, enabling the surgeon to understand the positional relationship between the preoperative image and the actual surgical site, with the naked eye. | Hideyuki Suenaga Huy Hoang Tran Hongen Liao Ken Masamune Takeyoshi Dohi Kazuto Hoshi Yoshiyuki Mori Tsuyoshi Takato | 2013 | International Journal of Oral Science2013，5，2： | 11 |

| 9 | Evaluation of magnifying colonoscopy in the diagnosis of serrated polyps显示文摘AIM:To elucidate the colonoscopic features of serrated lesions of the colorectum using magnifying colonoscopy.METHODS:Broad division of serrated lesions of the colorectum into hyperplastic polyps(HPs),traditional serrated adenomas(TSAs),and sessile serrated adenomas/polyps(SSA/Ps) has been proposed on the basis of recent molecular biological studies.However,few reports have examined the colonoscopic features of these divisions,including magnified colonoscopic findings.This study examined 118 lesions excised in our hospital as suspected serrated lesions after magnified observation between January 2008 and September 2011.Patient characteristics(sex,age),conventional colonoscopic findings(location,size,morphology,color,mucin) and magnified colonoscopic findings(pit pattern diagnosis) were interpreted by five colonoscopists with experience in over 1000 colonoscopies,and were compared with histopathological diagnoses.The pit patterns were categorized according to Kudo's classification,but a more detailed investigation was also performed using the subclassification [type Ⅱ-Open(type Ⅱ-O),type Ⅱ-Long(type Ⅱ-L),or type Ⅳ-Serrated(type Ⅳ-S)] proposed by Kimura T and Yamano H.RESULTS:Lesions comprised 23 HPs(23/118:19.5%),39 TSAs(39/118:33.1%:with cancer in one case),50 SSA/Ps(50/118:42.4%:complicated with cancer in three cases),and six others(6/118:5.1%).We excluded six others,including three regular adenomas,one hamartoma,one inflammatory polyp,and one juvenile polyp for further analysis.Conventional colonoscopy showed that SSA/Ps were characterized as larger in diameter than TSAs and HPs(SSA/P vs HP,13.62 ± 8.62 mm vs 7.74 ± 3.24 mm,P < 0.001;SSA/Ps vs TSA,13.62 ± 8.62 mm vs 9.89 ± 5.73 mm,P < 0.01);common in the right side of the colon [HPs,30.4%(7/23):TSAs,20.5%(8/39):SSA/P,84.0%(42/50),P < 0.001];flat-elevated lesion [HPs,30.4%(7/23):TSAs,5.1%(2/39):SSA/Ps,90.0%(45/50),P < 0.001];normal-colored or pale imucosa [HPs,34.8%(8/23):TSAs,10.3%(4/39):SSA/Ps,80%(40/50),P < 0.001];and with large amounts of mucin [HPs,21.7%(5/23):TSAs,17.9%(7/39):SSA/Ps,72.0%(36/50),P < 0.001].In magnified colonoscopic findings,17 lesions showed either type Ⅱ pit pattern alone or partial type Ⅱ pit pattern as the basic architecture,with 14 HPs(14/17,70.0%) and 3 SSA/Ps.Magnified colonoscopy showed the type Ⅱ-O pit pattern as characteristic of SSA/Ps [sensitivity 83.7%(41/49),specificity 85.7%(54/63)].Cancer was also present in three lesions,in all of which a type Ⅵ pit pattern was also present within the same lesion.There were four HPs and four TSAs each.The type Ⅳ-S pit pattern was characteristic of TSAs [sensitivity 96.7%(30/31),specificity 89.9%(72/81)].Cancer was present in one lesion,in which a type Ⅵ pit pattern was also present within the same lesion.In our study,serrated lesions of the colorectum also possessed the features described in previous reports of conventional colonoscopic findings.The pit pattern diagnosis using magnifying colonoscopy,particularly magnified colonoscopic findings using subclassifications of surface architecture,reflected the pathological characteristics of SSA/Ps and TSAs,and will be useful for colonoscopic diagnosis.CONCLUSION:We suggest that this system could be a good diagnostic tool for SSA/Ps using magnifying colonoscopy. | Shinya Ishigooka Masahito Nomoto Nobuyuki Obinata Yoshichika Oishi Yoshinori Sato Satoko Nakatsu Midori Suzuki Yoshiko Ikeda Tadateru Maehata Tomoaki Kimura Yoshiyuki Watanabe Takashi Nakajima Hiro-o Yamano Hiroshi Yasuda Fumio Itoh | 2012 | World Journal of Gastroenterology2012，18，32： | 11 |

They were three men and two woman, aged 36-56 years. Tumors located in the cardia were completely enucleated endoscopically without any serious complication. The largest diameter of removed tumors ranged from 1.2 to 2.5 cm. Histopathological diagnosis was GIST with low risk of malignancy (mitotic index < 5/50 high power field) in all cases. The patients were disease-free for 10.5-42.2 mo after endoscopic enucleation. | Toshio Katoh Yoshiyuki Itoh Tomomi Mohri Hiroshi Suzuki | 2008 | World Journal of Gastroenterology2008，14，16： | 11 |
| 11 | Antioxidant Defense Mechanisms of Salinity Tolerance in Rice Genotypes显示文摘In order to elucidate the role of antioxidant responses in salinity tolerance in rice genotypes under salt stress, experiments were conducted using four rice varieties, including salt-sensitive BRRI dhan 28 and three salt-tolerant varieties BRRI dhan 47, BINA dhan 8 and BINA dhan 10. Thirty-day-old rice seedlings were transplanted into pots. At the active tillering stage(35 d after transplanting), plants were exposed to different salinity levels(0, 20, 40 and 60 mmol/L NaCl). Salt stress caused a significant reduction in growth for all the rice genotypes. Growth reduction was higher in the salt-sensitive genotype than in the salt-tolerant ones, and BINA dhan 10 showed higher salt tolerance in all measured physiological parameters. The reduction in shoot and root biomass was found to be minimal in BINA dhan 10. Chlorophyll content significantly decreased under salt stress except for BINA dhan 10. Proline content significantly increased in salt-tolerant rice genotypes with increased salt concentration, and the highest proline content was obtained from BINA dhan 10 under salt stress. Catalase and ascorbate peroxidase activities significantly decreased in salt-sensitive genotype whereas significantly increased in salt-tolerant ones with increasing salt concentration. However, salt stress significantly decreased guaiacol peroxidase activity in all the rice genotypes irrespective of salt tolerance. K^+/Na^+ ratio also significantly decreased in shoots and roots of all the rice genotypes. The salt-tolerant genotype BINA dhan 10 maintained higher levels of chlorophyll and proline contents as well as catalase and ascorbate peroxidase activities under salt stress, thus, this might be the underlying mechanism for salt tolerance. | Mohammad Golam KIBRIA Mahmud HOSSAIN Yoshiyuki MURATA Md.Anamul HOQUE | 2017 | Rice science2017，24，3： | 10 |
| 12 | 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 |
| 13 | Prognostic value of postoperative complication for early recurrence after curative resection of hepatocellular carcinoma显示文摘Background: Postoperative complications may adversely affect oncological outcomes. The aim of this study was to evaluate the impact of postoperative complications on early-phase recurrence after curative resection for hepatocellular carcinoma(HCC).Methods: We included 145 HCC patients who underwent initial and curative resection between January2004 and December 2013. Postoperative complications of grade III or higher based on Clavien–Dindo classification were defined as clinically relevant postoperative complications. Recurrence within two years after hepatectomy was defined as early-phase recurrence.Results: Thirty-eight patients(26%) developed postoperative complications. The only predictive factor for postoperative complication was longer operative duration(P = 0.037). The disease-specific survival rate of patients with complication was lower than that of patients without complications(P = 0.015). Earlyphase recurrence was observed in 20/38(53%) patients who suffered postoperative complications and36/107(34%) patients with no complications, which was statistically significant(P = 0.039). Multivariate analysis identified four factors contributing to early-phase recurrence: high serum AFP level(P = 0.042),multiple tumors(P < 0.001), poor differentiation(P = 0.036) and presence of postoperative complication(P = 0.039).Conclusions: Postoperative complication is an independent prognostic factor for early-phase recurrence after curative resection of HCC. Close observation of patients with postoperative complications may be a necessary treatment strategy for HCC. | Masataka Amisaki Hiroaki Saito Naruo Tokuyasu Teruhisa Sakamoto Soichiro Honjo Yoshiyuki Fujiwara | 2018 | Hepatobiliary & Pancreatic Diseases International2018，17，4： | 10 |
| 14 | Meropenem as an Alternative Antibiotic Agent for Suppression of Agrobacterium in Genetic Transformation of Orchid显示文摘A case of Meropenem as a novel antibacterial agent to suppress and eliminate Agrobacterium tumefaciens in the Agrobacterium-mediated transformation of orchid protocorm-like bodies (PLBs) has been reported in this article. The in vitro activities of meropenem and four comparator antibacterial agents against three Agrobacterium tumefaciens strains, LBA4404, EHA101, and GV3101, were assessed. In addition, the effect of meropenem on the growth of Dendrobium phalaenopsis PLBs was determined. Compared with other commonly used antibiotics (including ampicillin, carbenicillin, cefotaxime, and cefoperazone), meropenem showed the highest activity in suppressing all tested A. tumefaciens strains (minimum inhibitory concentration [MIC] < 0.5 mg L-1, which is equal to minimum bactericidal concentration [MBC]). Meropenem, at all tested concentrations, except for 10 mg L-1 concentration, had little negative effect on the growth of orchid tissues. The A. tumefaciens strain EHA101 in genetic transformation with vector pIG121Hm in infected PLBs of the orchid was visually undetectable after a two-month subculture in 1/2 MS medium with 50 mg L-1 meropenem and 25 mg L-1 hygromacin. The expression and incorporation of the transgenes were confirmed by GUS histochemical assay and PCR analysis. Meropenem may be an alternative antibiotic for the effective suppression of A. tumefaciens in genetic transformation. | CAO Ying Niimi Yoshiyuki HU Shang-lian | 2006 | Agricultural Sciences in China2006，5，11： | 9 |
| 15 | 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 |
| 16 | Post-operative albumin-bilirubin grade predicts long-term outcomes among Child–Pugh grade A patients with hepatocellular carcinoma after curative resection显示文摘Background: Although Child–Pugh grade A patients with hepatocellular carcinoma(HCC) are candidates for curative resection, some may have a poor prognosis. The albumin-bilirubin(ALBI) grade, a measure of liver function based on albumin and bilirubin, has the potential to detect Child–Pugh grade A HCC patients with poor prognosis. Because components of the ALBI grade can be measured easily even after surgery, we explored the predictive values of ALBI in patient prognosis after HCC resection. Methods: In this retrospective case-control study, we included 136 HCC patients who underwent curative resection between January 2004 and December 2013 at our hospital. ALBI grade was calculated from laboratory data recorded the day before surgery and at post-operative day 5. Results: Pre-and post-operative ALBI grade predicted patients' long-term outcomes( P = 0.020 and P < 0.001, respectively, for overall survival, and P = 0.012 and P = 0.015, respectively, for recurrence-free survival). Post-operative ALBI grade was associated with patients' surgical factors of repeated hepatic resection( P = 0.012), intra-operative bleeding( P = 0.006), and surgery duration( P = 0.033). Furthermore, post-operative ALBI grade, rather than pre-operative ALBI grade, was an independent predictive factor of long-term outcome of Child–Pugh grade A patients with HCC. Conclusions: Post-operative ALBI grade is useful to predict the prognosis in patients after HCC resection. | Masataka Amisaki Ei Uchinaka Masaki Morimoto Naruo Tokuyasu Teruhisa Sakamoto Soichiro Honjo Hiroaki Saito Yoshiyuki Fujiwara | 2018 | Hepatobiliary & Pancreatic Diseases International2018，17，6： | 9 |
| 17 | The influence of asymptomatic inflammatory prostatitis on the onset and progression of lower urinary tract symptoms in men with histologic benign prostatic hyperplasia显示文摘Benign prostatic hyperplasia(BPH)is a condition that greatly affects the quality of life of middle-aged and elderly men.Histopathologically,hyperplastic changes frequently occur in the prostate tissue of elderly men,the incidence of which has been reported to reach approximately 80% in men in their 70s.In clinical practice,approximately 25% of men with histologic BPH are assumed to experience lower urinary tract symptoms(LUTS)and receive some kind of treatment.In other words,there are some men with histologic BPH who do not exhibit LUTS.For that reason,many factors,such as the change in hormonal environment,the immune or autoimmune response,the alteration of gene expression,and so on,are thought to affect the onset and progression of LUTS in men with histologic BPH.One such factor that has long drawn attention is the presence of asymptomatic histological inflammation,which very often accompanies symptomatic BPH.Recent studies have suggested that asymptomatic histological inflammation causes repeated destruction,healing,and regeneration of the prostate tissue,leading to the enlargement of prostatic nodules,while at the same time causing stromal tissuepredominant remodeling of the prostate tissue,which can increase urination resistance and result in the condition changing from asymptomatic BPH to symptomatic BPH.In future,the biomolecular clarification of the significance of asymptomatic histological inflammation in the prostate tissue could help develop new treatment strategies for BPH accompanied by LUTS. | Rikiya Taoka Yoshiyuki Kakehi | 2017 | Asian Journal of Urology2017，4，3： | 9 |
| 18 | Making continental crust:The sanukitoid connection显示文摘The average continental crust possesses intermediate compositions that typify arc magmatism and as a result it is believed to have been created at ancient convergent plate boundaries. One possible mechanism for intermediate continental crust formation is the direct production of andesitic melts in the upper mantle. Sanukitoids, which characterize the Setouchi volcanic belt, SW Japan, include un-usually high-Mg andesites (HMA). They were generated by slab melting and subsequent melt-mantle interactions under unusual tectonic settings such as where warm lithosphere subducts into hot upper mantle. Such conditions would have existed in the Archean. Hydrous HMA magmas are likely to have solidified within the crust to form HMA plutons, which were then remelted to produce differentiated sanukitoids. At present, generation and differentiation of HMA magmas may be taking place in the Izu-Bonin-Mariana arc-trench system (IBM), because (1) HMA magmatism characterizes the initial stages of the IBM evolution and (2) the IBM middle crust exhibits Vp identical to that of the bulk conti-nental crust. Vp estimates for plutonic rocks with HMA compositions support this. However tonalitic composition for middle-crust-forming rocks cannot be ruled out, suggesting an alternative possibility that the continental crust has been created by differentiation of mantle-derived basaltic magmas. | Yoshiyuki TATSUMI | 2008 | Chinese Science Bulletin2008，53，11： | 8 |
| 19 | Hepatitis C virus enhances incidence of idiopathic pulmonary fibrosis显示文摘AIM: To investigate the cumulative development incidence and predictive factors for idiopathic pulmonary fibrosis in hepatitis C virus (HCV) positive patients. METHODS: We studied 6150 HCV infected patients who were between 40-70 years old (HCV-group). Another 2050 patients with hepatitis B virus (HBV) were selected as control (HBV-group). The mean observation period was 8.0 ± 5.9 years in HCV-group and 6.3 ± 5.5 years in HBV-group. The primary goal is the development of idiopathic pulmonary fibrosis (IPF) in both groups. The cumulative appearance rate of IPF and independent factors associated with the incidence rate of IPF were calculated using the Kaplan- Meier method and the Cox proportional hazard model. All of the studies were performed retrospectively by collecting and analyzing data from the patient records in our hospital. RESULTS: Fifteen patients in HCV-group developedIPF. On the other hand, none of the patients developed IPF in HBV-group. In HCV-group, the cumulative rates of IPF development were 0.3% at 10th year and 0.9% at 20th year. The IPF development rate in HCV-group was higher than that in HBV-group (P = 0.021). The IPF development rate in patients with HCV or HBV was high with statistical significance in the following cases: (1) patients ≥ 55 years (P < 0.001); (2) patients who had smoking index (package per day × year) of ≥ 20 (P = 0.002); (3) patients with liver cirrhosis (P = 0.042). CONCLUSION: Our results indicate that age, smoking and liver cirrhosis enhance the development of IPF in HCV positive patients. | Yasuji Arase Fumitaka Suzuki Yoshiyuki Suzuki Norio Akuta Masahiro Kobayashi Yusuke Kawamura Hiromi Yatsuji Hitomi Sezaki Tetsuya Hosaka Miharu Hirakawa Satoshi Saito Kenji Ikeda Hiromitsu Kumada | 2008 | World Journal of Gastroenterology2008，14，38： | 8 |
| 20 | Drag-reduction of a nonionic surfactant aqueous solution and its rheological characteristics显示文摘In order to develop turbulent drag-reducing technology by using an environmentally friendly additive in a water-transporting system,the drag reducing characteristics in a non-ionic surfactant(Oleyldimethylamineoxide,ODMAO) dilute aqueous solution flowing in a circular pipe of 5 mm diameter have been experimentally investigated with an air-driven fluid resistance test device.The rheological characteristics of the solution have also been examined by a rheometer with a cone-plate flow cell.The results show that the ODMAO solutions are drag-reducing when concentration is 400 ppm or higher,that the critical Reynolds number corresponding to the maximum drag reduction rate increases with both concentration and temperature,and that the maximum drag reduction rate can reach up to 70% in the straight pipe.At low shear rates,the shear viscosity of ODMAO solutions with a relatively high drag-reduction behaves similarly to Newtonian fluids;at above a certain critical shear rate,it is firstly shear-thickening,then shear-thinning.Such shear-rate-dependent characteristics of the shear viscosity are attributed to the different transitions of micellar network structure induced by different shear rates.Relaxation of shear stress after removing an applied constant shear rate at which the solution is in the SIS(shear-induced structure) state is found to be well expressed by a 2-step Maxwell model with a tail relaxation time much shorter than that for a drag-reducing cationic surfactant,which indicates that for the ODMAO solution,a viscoelasticity as strong as a drag-reducing cationic surfactant is not needed to realize turbulent drag-reduction. | CAI ShuPeng SUZUKI Hiroshi KOMODA Yoshiyuki | 2012 | Science China(Technological Sciences)2012，55，3： | 7 |
