| 1 | Compound Danshen injection improves endotoxin-induced microcirculatory disturbance in rat mesentery显示文摘AIM: To investigate the effect of compound Danshen injection on lipopolysaccharide (LPS)-induced rat mesenteric microcirculatory dysfunctions and the underlying possible mechanism by an inverted intravital microscope and high-speed video camera system. METHODS: LPS was continuously infused through the jugular artery of male Wistar rats at the dose of 2 mg/kg per hour. Changes in mesenteric microcirculation,such as diameters of arterioles and venules,velocity of RBCs in venules,leukocyte rolling,adhesion and emigration,free radicals released from post-capillary venules,FITC- albumin leakage and mast cell degranulation,were observed through an inverted intravital microscope assisted with CCD camera and SIT camera. Meanwhile,the expression of adhesion molecules CD11b/CD18 and the production of free radical in neutrophils,and the expression of intercellular adhesion molecule 1 (ICAM-1) in human umbilical vein endothelial cells (HUVECs) were quantified by flow cytometry (FACS) in vitro. RESULTS: The continuous infusion with LPS resulted in a number of responses in microcirculation,including a significant increase in the positive region of venulestained with Monastral blue B,rolling and adhesion of leukocytes,production of oxygen radical in venular wall,albumin efflux and enhanced mast cell degranulation in vivo,all of which,except for the leukocyte rolling,were attenuated by the treatment with compound Danshen injection. Experiments performed in vitro further revealed that the expression of CD11b/CD18 and the production of oxygen free radical in neutrophils,and the expression of ICAM-1 in HUVECs were increased by exposure to LPS,and they were attenuated by compound Danshen injection. CONCLUSION: These results suggest that compound Danshen injection is an efficient drug with multi-targeting potential for improving the microcirculatory disturbance. | Jing-Yan Han Yoshinori Horie Soichiro Miura, Yasutada Akiba Jun Guo Dan Li Jing-Yu Fan Yu-Ying Liu Bai-He Hu Li-Hua An Xin Chang Man Xu De-An Guo Kai Sun Ji-Ying Yang Shu-Ping Fang Ming-Ji Xian Masahiro Kizaki Hiroshi Nagata Toshifumi Hibi | 2007 | World Journal of Gastroenterology2007，13，26： | 26 |
| 2 | 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 |

| 5 | High expressions of caveolins on the proliferating bile ductules in primary biliary cirrhosis显示文摘AIM: An increase in bile ductular structures is observed in diverse human liver diseases, especially in primary biliary cirrhosis (PBC). These structures harbor the progenitor cell component of the liver. Caveolins are cholesterol-binding proteins involved in the regulation of several intracellular processes including cholesterol transport. This study aims to examine the role of caveolin in PBC.METHODS: Immunohistochemical and Western blottingstudies were performed on human liver specimens obtained from patients with PBC and normal liver samples. The expression of caveolin (CAV)-1 and -2 was determined using specific antibodies.RESULTS: In normal liver, scanty immunostaining for CAV1 and -2 was observed in bile ductules. In PBC liver samples, the expression levels of CAV-1 and -2 were increased on proliferating bile ductules especially in stage 3 cases, but was sparse on interlobular bile duct in stage 1 specimens. Especially, the regenerating bile ductules at the interface of portal tracts and necrotic areas were immunostained intensely for CAV-1 and -2. These phenomena were confirmed by Western blot.CONCLUSION: The present results demonstrate increased expression of caveolins in proliferating bile ductules in PBC, which may be related to the homeostasis of cholesterol transport in regenerating bile ductules in PBC liver. | Hiroaki Yokomori Masaya Oda Go Wakabayashi Masaki Kitajima Kazunori Yoshimura Masahiko Nomura Toshifumi Hibi | 2005 | World Journal of Gastroenterology2005，11，24： | 4 |
| 6 | Dual therapy for third-line Helicobacter pylori eradication and urea breath test prediction显示文摘We evaluated the efficacy and tolerability of a dual therapy with rabeprazole and amoxicillin (AMX) as an empiric third-line rescue therapy. In patients with failure of first-line treatment with a proton pump inhibitor (PPI)- AMX-clarithromycin regimen and second-line treatment with the PPI-AMX-metronidazole regimen, a third-line eradication regimen with rabeprazole (10 mg q.i.d.) and AMX (500 mg q.i.d.) was prescribed for 2 wk. Eradication was confirmed by the results of the 13C-urea breath test (UBT) at 12 wk after the therapy. A total of 46 patients were included; however, two were lost to followup. The eradication rates as determined by per-protocol and intention-to-treat analyses were 65.9% and 63.0%,respectively. The pretreatment UBT results in the subjects showing eradication failure; those patients showing successful eradication comprised 32.9 ± 28.8 permil and 14.8 ± 12.8 permil, respectively. The pretreatment UBT results in the subjects with eradication failure were significantly higher than those in the patients with successful eradication (P = 0.019). A low pretreatment UBT result (≤ 28.5 permil) predicted the success of the eradication therapy with a positive predictive value of 81.3% and a sensitivity of 89.7%. Adverse effects were reported in 18.2% of the patients, mainly diarrhea and stomatitis. Dual therapy with rabeprazole and AMX appears to serve as a potential empirical third-line strategy for patients with low values on pretreatment UBT. | Toshihiro Nishizawa Hidekazu Suzuki Takama Maekawa Naohiko Harada Tatsuya Toyokawa Toshio Kuwai Masanori Ohara Takahiro Suzuki Masahiro Kawanishi Kenji Noguchi Toshiyuki Yoshio Shinji Katsushima Hideo Tsuruta Eiji Masuda Munehiro Tanaka Shunsuke Katayama Norio Kawamura Yuko Nishizawa Toshifumi Hibi Masahiko Takahashi | 2012 | World Journal of Gastroenterology2012，18，21： | 4 |
| 7 | Expression of adhesion molecules on mature cholangiocytes in canal of Hering and bile ductules in wedge biopsy samples of primary biliary cirrhosis显示文摘AIM: To examine the expression of intercellular adhesion molecule-1 (ICAM-1) and lymphocyte function-associated antigen-1 (LFA-1) expression on canals of Hering (CoH)and bile ductules associated with the autoimmune process of bile duct destruction in primary biliary cirrhosis (PBC).METHODS: Ten wedged liver biopsies of PBC (five cases each of stages 2 and 3) were studied. The liver specimens were processed for transmission electron microscopy.Immunohistochemistry was performed using anti-ICAM-1 and anti-LFA-1 mouse mAbs. In situ hybridization was done to examine the messenger RNA expression of ICAM-1 in formalin-fixed, paraffin-embedded sections using peptide nucleic acid probes and the catalyzed signal amplification (CSA) technique. Immunogold-silver staining for electron microscopy was performed using anti-ICAM and anti-LFA-1 mouse mAbs. The immunogold particles on epithelial cells of bile ductules and cholangiocytes of CoH cells were counted and analyzed semi-quantitatively.Western blotting was performed to confirm ICAM-1 protein expression.RESULTS: In liver tissues of PBC patients, immunohistochemistry showed aberrant ICAM-1 expression on the plasma membrane of epithelial cells lining bile ductules,and also on mature cholangiocytes but not on hepatocytes in CoH. LFA-1-positive lymphocytes were closely associated with epithelial cells in bile ductules. ICAM-1 expression at protein level was confirmed by Western blot. In situ hybridization demonstrated ICAM-1 mRNA expression in bile ductules and LFA-1 mRNA in lymphocytes infiltrating the bile ductules. By immunoelectron microscopy, ICAM-1 was demonstrated on the basal surface of epithelial cells in bile ductules and on the luminal surfaces of cholangiocytes in damaged CoH. Cells with intermediate morphology resembling progenitor cells in CoH were not labeled with ICAM-1 and LFA-1.CONCLUSION: De novo expression of ICAM-1 both on mature cholangiocytes in CoH and epithelial cells in bile ductules in PBC implies that lymphocyte-induced destruction through adhesion by ICAM-1 and binding of LFA-1-expressing activated lymphocytes takes place not only in bile ductules but also in the CoH. | Hiroaki Yokomori Masaya Oda Mariko Ogi Go Wakabayashi Shigeyuki Kawachi Kazunori Yoshimura Toshihiro Nagai Masaki Kitajima Masahiko Nomura Toshifumi Hibi | 2005 | World Journal of Gastroenterology2005，11，28： | 4 |
| 8 | Pre-hepatectomy type Ⅳ collagen 7S predicts post-hepatectomy liver failure and recovery显示文摘BACKGROUND Liver resection is an effective treatment for benign and malignant liver tumors.However,a method for preoperative evaluation of hepatic reserve has not yet been established.Previously reported assessments of preoperative hepatic reserve focused only on liver failure in the early postoperative period and did not consider the long-term recovery of hepatic reserve.When determining eligibility for hepatectomy,the underlying pathophysiology needs to be considered to determine if the functional hepatic reserve can withstand both surgery and any postoperative therapy.AIM To identify pre-hepatectomy factors associated with both early postoperative liver failure and long-term postoperative liver function recovery.METHODS This study was a retrospective cohort study.We retrospectively investigated 215 patients who underwent hepatectomy at our hospital between May 2013 and December 2016.Early post-hepatectomy liver failure(PHLF)was defined using the International Study Group of Liver Surgery’s definition of PHLF.Long-term postoperative recovery of liver function was defined as the time taken for serum total bilirubin and albumin levels to return to levels of<2 mg/dL and>2.8 g/dL,respectively,and the time taken for Child-Pugh score to return to Child-Pugh class A.RESULTS Preoperative type IV collagen 7S was identified as a significant independent factor associated with both PHLF and postoperative long-term recovery of liver function.Further analysis revealed that the time taken for the recovery of Child-Pugh scores and serum total bilirubin and albumin levels was significantly shorter in patients with type IV collagen 7S≤6 ng/mL than in those with type IV collagen 7S>6 ng/mL.In additional analyses,similar results were observed in patients without chronic viral hepatitis associated with fibrosis.CONCLUSION Preoperative type IV collagen 7S is a preoperative predictor of PHLF and longterm postoperative liver function recovery.It can also be used in patients without chronic hepatitis virus. | Masatsugu Ishii Osamu Itano Masahiro Shinoda Minoru Kitago Yuta Abe Taizo Hibi Hiroshi Yagi Ayano Takeuchi Hanako Tsujikawa Tokiya Abe Yuko Kitagawa | 2020 | World Journal of Gastroenterology2020，26，7： | 3 |

| 11 | An antioxidant resveratrol significantly enhanced replication of hepatitis C virus显示文摘AIM:To elucidate the effect of antioxidants,resveratrol (RVT)and astaxanthin(AXN),on hepatitis C virus(HCV) replication. METHODS:We investigated the effect of recent popular antioxidant supplements on replication of the HCV replicon system OR6.RVT is a strong antioxidant and a kind of polyphenol that inhibits replication of various viruses.AXN is also a strong antioxidant.The replication of HCV RNA was assessed by the luciferase reporter assay.An additive effect of antioxidants on antiviral effects of interferon(IFN)and ribavirin(RBV) was investigated.RESULTS:This is the first report to investigate the effect of RVT and AXN on HCV replication.In contrast to other reported viruses,RVT significantly enhanced HCV RNA replication.Vitamin E also enhanced HCV RNA replication as reported previously,although AXN didnot affect replication.IFN and RBV significantly reduced HCV RNA replication,but these effects were dose-dependently hampered and attenuated by the addition of RVT.AXN didnot affect antiviral effects of IFN or RBV. CONCLUSION:These results suggested that RVT is not suitable as an antioxidant therapy for chronic hepatitis C. | Mitsuyasu Nakamura Masanori Ikeda Ryota Hokari Nobuyuki Kato Toshifumi Hibi Soichiro Miura | 2010 | World Journal of Gastroenterology2010，16，2： | 3 |
| 12 | Enhanced plasma ghrelin levels in Helicobacter py/ori-colonized, interleukin-1-receptortype 1-homozygous knockout (IL-1R1-/-) mice显示文摘AIM: Ghrelin is an endogenous ligand for the growth hormone secretagogue receptor, and it plays a role in stimulating the growth hormone secretion, food intake, body weight gain and gastric motility. Eradication of Helicobacterpylori (H pylori) was shown to be associated with increase of the body weight. On the other hand, H pylori infection evokes the release of gastric IL-lp. The present study was designed to investigate the involvement of the gastric IL-1 signal in the ghrelin dynamics in Hpylori-colonized mice. METHODS: Twelve-week-old female IL-1-receptor type 1-homozygous-knockout mice (IL-1R1-/-') and their wild-type littermates (WT) were orally inoculated with H pylori (Hp group), while other cohorts received oral inoculation of culture medium (Cont group). Thirteen weeks after the inoculation, the mice were examined. The plasma and stomach ghrelin levels and the gastric preproghrelin mRNA were measured. RESULTS: Although the WT mice with H pylori infection showed a significantly decreased body weight as compared with that of the animals without H pylori infection, H pylori infection did not influence the body weight of the IL-1R1-knockout (IL-1R1-/-) mice. In the H pylori-infected IL-1R1-/-mice, the total and active ghrelin levels in the plasma were significantly increased, and the gastric ghrelin level was decreased. No significant differences were noted in the gastric preproghrelin mRNA expression. CONCLUSION: Ghrelin secretion triggered by H pylori infection might be suppressed by IL-1β, the release of which is also induced by the infection, resulting in the body weight loss of mice with H pylori infection. | Yuka Abiko Hidekazu Suzuki Tatsuhiro Masaoka Sachiko Nomura Kumiko Kurabayashi Hiroshi Hosoda Kenji Kangawa Toshifumi Hibi | 2005 | World Journal of Gastroenterology2005，11，27： | 3 |

| 14 | Percutaneous endoscopic gastrostomy under steadypressure automatically controlled endoscopy:First clinicalseries显示文摘AIM: To elucidate the safety of percutaneous endoscopic gastrostomy(PEG) under steady pressure automatically controlled endoscopy(SPACE) using carbon dioxide(CO_2).METHODS: Nine patients underwent PEG with a modified introducer method under conscious sedation. A T-tube was attached to the channel of an endoscope connected to an automatic surgical insufflator. The stomach was inflated under the SPACE system. The intragastric pressure was kept between 4-8 mmH g with a flow of CO_2 at 35 L/min. Median procedure time, intragastric pressure, median systolic blood pressure, partial pressure of CO_2, abdominal girth before and immediately after PEG, and free gas and small intestinal gas on abdominal X-ray before and after PEG were recorded. RESULTS: PEG was completed under stable pneumostomach in all patients, with a median procedural time of 22 min. Median intragastric pressure was 6.9 mmH g and median arterial CO_2 pressure before and after PEG was 42.1 and 45.5 Torr(NS). The median abdominal girth before and after PEG was 68.1 and 69.6 cm(NS). A mild free gas image after PEG was observed in two patients, and faint abdominal gas in the downstream bowel was documented in two patients.CONCLUSION: SPACE might enable standardized pneumostomach and modified introducer procedure of PEG. | Hiroyuki Imaeda Kiyokazu Nakajima Naoki Hosoe Masanori Nakahara Shinichiro Zushi Motohiko Kato Kazuhiro Kashiwagi Yasushi Matsumoto Kayoko Kimura Rieko Nakamura Norihito Wada Masahiko Tsujii Naohisa Yahagi Toshifumi Hibi Takanori Kanai Tetsuo Takehara Haruhiko Ogata | 2016 | World Journal of Gastrointestinal Endoscopy2016，8，3： | 2 |
