| 1 | Correlation between hepatic blood flow and liver function in alcoholic liver cirrhosis显示文摘AIM:To elucidate the correlation between hepatic blood flow and liver function in alcoholic liver cirrhosis(AL-LC).METHODS:The subjects included 35 patients with ALLC(34 men,1 woman;mean age,58.9±10.7 years;median age,61 years;range:37-76 years).All patientswere enrolled in this study after obtaining written informed consent.Liver function was measured with tests measuring albumin(Alb),prothrombin time(PT),brain natriuretic peptide(BNP),branched amino acid and tyrosine ratio(BTR),branched chain amino acid(BCAA),tyrosine,ammonia(NH3),cholinesterase(Ch E),immunoreactive insulin(IRI),total bile acid(TBA),and the retention rate of indocyanine green 15 min after administration(ICG R15).Hepatic blood flow,hepatic arterial tissue blood flow(HATBF),portal venous tissue blood flow(PVTBF),and total hepatic tissue blood flow(THTBF)were simultaneously calculated using xenon computed tomography.RESULTS:PVTBF,HATBF and THTBF were 30.2±10.4,20.0±10.7,and 50.3±14.9 m L/100 m L/min,respectively.Alb,PT,BNP,BTR,BCAA,tyrosine,NH3,Ch E,IRI,TBA,and ICG R15 were 3.50±0.50 g/d L,72.0%±11.5%,63.2±56.7 pg/m L,4.06±1.24,437.5±89.4μmol/L,117.7±32.8μmol/L,59.4±22.7μg/d L,161.0±70.8 IU/L,12.8±5.0μg/d L,68.0±51.8μmol/L,and 28.6%±13.5%,respectively.PVTBF showed a significant negative correlation with ICG R15(r=-0.468,P<0.01).No significant correlation was seen between ICG 15R,HATBF and THTBF.There was a significant correlation between PVTBF and Alb(r=0.2499,P<0.05),and NH3 tended to have an inverse correlation with PVTBF(r=-0.2428,P=0.0894).There were also many significant correlations between ICG R15 and liver function parameters,including Alb,NH3,PT,BNP,TBA,BCAA,and tyrosine(r=-0.2156,P<0.05;r=0.4318,P<0.01;r=0.4140,P<0.01;r=0.3610,P<0.05;r=0.5085,P<0.001;r=0.4496,P<0.01;and r=0.4740,P<0.05,respectively).CONCLUSION:Our investigation showed that there is a close correlation between liver function and hepatic blood flow. | Hideaki Takahashi Ryuta Shigefuku Yoshihito Yoshida Hiroki Ikeda Kotaro Matsunaga Nobuyuki Matsumoto Chiaki Okuse Shigeru Sase Fumio Itoh Michihiro Suzuki | 2014 | World Journal of Gastroenterology2014，20，45： | 14 |
| 2 | Prospective postsurgical capsule endoscopy in patients with Crohn's disease显示文摘AIM: To clarify the usefulness of postsurgical capsule endoscopy(CE) in the diagnosis of recurrent small bowel lesions of Crohn's disease(CD). METHODS: This prospective study included 19 patients who underwent ileocolectomy or partial ileal resection for CD. CE was performed 2-3 wk after surgery to check for the presence/absence and severity of lesions remaining in the small bowel, and for any recurrence at the anastomosed area. CE was repeated 6-8 mo after surgery and the findings were compared with those obtained shortly after surgery. The Lewis score (LS) was used to evaluate any inflammatory changes of the small bowel. RESULTS: One patient was excluded from analysis because of insufficient endoscopy data at the initial CE. The total LS shortly after surgery was 428.3 on average(median, 174; range, 8-4264), and was ≥ 135(active stage) in 78%(14 of 18) of the patients. When the remaining unresected small bowel was divided into 3 equal portions according to the transition time(proximal, middle, and distal tertiles), the mean LS was 286.6, 83.0, and 146.7, respectively, without any significant difference. Ulcerous lesions in the anastomosed area were observed in 83% of all patients. In 38% of the 13 patients who could undergo CE again after 6-8 mo, the total LS was higher by ≥ 100 than that recorded shortly after surgery, thus indicating a diagnosis of endoscopic progressive recurrence. CONCLUSION: Our pilot study suggests that CE can be used to objectively evaluate the postoperative recurrence of small bowel lesions after surgery for CD. | Tomoaki Kono Nobuyuki Hida Koji Nogami Masaki Iimuro Yoshio Ohda Yoko Yokoyama Koji Kamikozuru Katsuyuki Tozawa Mikio Kawai Tomohiro Ogawa Kazutoshi Hori Hiroki Ikeuchi Hiroto Miwa Shiro Nakamura Takayuki Matsumoto | 2014 | World Journal of Gastrointestinal Endoscopy2014，6，3： | 7 |
| 3 | Crowned dens syndrome developed after an endoscopic retrograde cholangiopancreatography procedure显示文摘We present a unique case of crowned dens syndrome(CDS) that developed after endoscopic retrograde cholangiopancreatography(ERCP) in a patient who presented with fever and neck pain. Administration of non-steroidal anti-inflammatory drugs was extremely effective for relieving fever and neck pain, and in the improvement of inflammatory markers. To the best of our knowledge, this is the first case report of CDS caused by an ERCP procedure. In a patient with fever and neck pain after an ERCP procedure, CDS should be considered in the differential diagnosis. | Hiroyasu Nakano Kazunari Nakahara Yosuke Michikawa Keigo Suetani Ryo Morita Nobuyuki Matsumoto Fumio Itoh | 2016 | World Journal of Gastroenterology2016，22，39： | 5 |

| 7 | Efficacy of MK615 for the treatment of patients with liver disorders显示文摘AIM:To investigate the hepatoprotective effect of MK615,a Japanese apricot extract,in an animal model,and its clinical therapeutic effect.METHODS:Wistar rats were administered physiological saline(4 mL/kg) or MK615 solution(4 mL/kg) for 7 d.On the sixth d,acute hepatic injury was induced by administering a single intraperitoneal injection(ip) of D-galactosamine hydrochloride(D-GalN)(600 mg/kg).Plasma levels of alanine aminotransferase(ALT) and aspartate aminotransferase(AST) were determined,and liver tissues were used for histopathological analysis.Fifty-eight patients with liver disorders [hepatitis C(n = 40),non-alcoholic fatty liver disease(n = 15),and autoimmune liver disease(n = 3)] were orally administered commercially available Misatol ME-containing MK615(13 g/d) daily for 12 wk.Blood and urine were sampled immediately before and 6 wk,12 wk,and 16 wk after the start of intake to measure various biochemical parameters.The percentage change in ALT and AST levels after 12 wk from the pre-intake baseline served as a primary endpoint.RESULTS:D-GalN effectively induced acute hepatic injury in the rats.At 48 h after the ip injection of D-GalN,the plasma levels of ALT(475.6 ± 191.5 IU/L vs 225.3 ± 194.2 IU/L,P < 0.05) and AST(1253.9 ± 223.4 IU/L vs 621.9 ± 478.2 IU/L,P < 0.05) in the MK615 group were significantly lower than the control group.Scattered single cell necrosis,loss of hepatocytes,and extensive inflammatory cell infiltration were observed in hepatic tissue samples collected from the control group.However,these findings were less pronounced in the group receiving MK615.At the end of the clinical study,serum ALT and AST levels were significantly decreased compared with pre-intake baseline levels from 103.5 ± 58.8 IU/L to 71.8 ± 39.3 IU/L(P < 0.05) and from 93.5 ± 55.6 IU/L to 65.5 ± 34.8 IU/L(P < 0.05),respectively.A reduction of ≥ 30% from the pre-study baseline ALT level was observed in 26(45%) of the 58 patients,while 25(43%) patients exhibited similar AST level reductions.The chronic hepatitis C group exhibited significant ALT and AST level reductions from 93.4 ± 51.1 IU/L to 64.6 ± 35.1 IU/L(P < 0.05) and from 94.2 ± 55.5 IU/L to 67.2 ± 35.6 IU/L(P < 0.05),respectively.A reduction of ≥ 30% from the pre-study baseline ALT level was observed in 20(50%) of the 40 patients.ALT levels in both the combined ursodeoxycholic acid(UDCA) treatment and the UDCA uncombined groups were significantly lower after Misatol ME administration.MK615 protected hepatocytes from D-GalN-induced cytotoxicity in rats.Misatol ME decreased elevated ALT and AST levels in patients with liver disorders.CONCLUSION:These results suggest that MK615 and Misatol ME are promising hepatoprotective agents for patients with liver disorders. | Atsushi Hokari Tomohisa Ishikawa Hisao Tajiri Takahide Matsuda Osamu Ishii Nobuyuki Matsumoto Chiaki Okuse Hideaki Takahashi Takeshi Kurihara Ko-ichi Kawahara Ikuro Maruyama Mikio Zeniya | 2012 | World Journal of Gastroenterology2012，18，31： | 2 |

| 16 | Enteral metallic stenting by balloon enteroscopy for obstruction of surgically reconstructed intestine显示文摘We present three cases of self-expandable metallic stent(SEMS) placement using a balloon enteroscope(BE) and its overtube(OT) for malignant obstruction of surgically reconstructed intestine. A BE is effective for the insertion of an endoscope into the deep bowel. However, SEMS placement is impossible through the working channel, because the working channel of BE is too small and too long for the stent device. Therefore, we used a technique in which the BE is inserted as far as the stenotic area; thereafter, the BE is removed, leaving only the OT, and then the stent is placed by inserting the stent device through the OT. In the present three cases, a modification of this technique resulted in the successful placement of the SEMS for obstruction of surgically reconstructed intestine, and the procedures were performed without serious complications. We consider that the present procedure is extremely effective as a palliative treatment for distal bowel stenosis, such as in the surgically reconstructed intestine. | Kazunari Nakahara Chiaki Okuse Nobuyuki Matsumoto Keigo Suetani Ryo Morita Yosuke Michikawa Shun-ichiro Ozawa Kosuke Hosoya Shinjiro Kobayashi Takehito Otsubo Fumio Itoh | 2015 | World Journal of Gastroenterology2015，21，24： | 1 |
