| 1 | Liver metastasis is the only independent prognostic factor in AFP-producing gastric cancer显示文摘AIM:To investigate differences between common gastric cancer andα-fetoprotein(AFP)-producing gastric cancer according to the presence or absence of liver metastasis.METHODS:Between 1997 and 2011,1299 patients underwent gastrectomy for gastric cancer(GC)at our institute and their hospital records were reviewed retrospectively.Patients were immunohistochemically divided into two groups:23 patients(1.8%)with AFPproducing GC and 1276 patients(98.2%)without it.RESULTS:AFP-producing GC patients had a significantly higher incidence of deeper tumors,venous invasion,lymphatic invasion,lymph node metastasis,and liver metastasis and a poorer prognosis(P<0.005)than those without AFP-producing GC.However,multi-variate analysis revealed that AFP-positivity was not an independent prognostic factor.The prognosis of AFPproducing GC was similar to that of AFP-non producing GC according to the presence or absence of liver metastasis.Concerning recurrence,47.8%of patients(11/23)with AFP-producing GC and 20.0%of patients(256/1276)without AFP-producing GC exhibited recurrence.Liver metastasis[90.9%(10/11)]was the most prevalent in AFP-producing GC patients.Multivariate analysis revealed that liver metastasis was the only independent prognostic factor in AFP-producing GC(HR=17.6,95%CI:2.1-147.1;P=0.0081).CONCLUSION:AFP-producing GC is similar to common GC without liver metastasis,which should be specifically targeted in an effort to improve the prognosis of AFP-producing GC patients. | Shoji Hirajima Shuhei Komatsu Daisuke Ichikawa Takeshi Kubota Kazuma Okamoto Atsushi Shiozaki Hitoshi Fujiwara Hirotaka Konishi Hisashi Ikoma Eigo Otsuji | 2013 | World Journal of Gastroenterology2013，19，36： | 33 |

| 3 | Progression of remnant gastric cancer is associated with duration of follow-up following distal gastrectomy显示文摘AIM: To re-evaluate the recent clinicopathological features of remnant gastric cancer (RGC) and to develop desirable surveillance programs. METHODS: Between 1997 and 2008, 1149 patients underwent gastrectomy for gastric cancer at the Department of Digestive Surgery, Kyoto Prefectural University of Medicine, Japan. Of these, 33 patients underwent gastrectomy with lymphadenectomy for RGC. Regarding the initial gastric disease, there were 19 patients with benign disease and 14 patients with gastric cancer. The hospital records of these patients were reviewed retrospectively. RESULTS: Concerning the initial gastric disease, the RGC group following gastric cancer had a shorter interval [P < 0.05; gastric cancer vs benign disease: 12 (2-22) vs 30 (4-51) years] and were more frequently reconstructed by Billroth-Ⅰ procedure than those following benign lesions (P < 0.001). Regarding reconstruction, RGC following Billroth-Ⅱ reconstruction showed a longer interval between surgical procedures [P < 0.001; Billroth-Ⅱ vs Billroth-Ⅰ: 32 (5-51) vs 12 (2-36) years] and tumors were more frequently associated with benign disease (P < 0.001) than those following Billroth-Ⅰ reconstruction. In tumor location of RGC, after Billroth-Ⅰ reconstruction, RGC occurred more frequently near the suture line and remnant gastric wall. After Billroth-Ⅱ reconstruction, RGC occurred more frequently at the anastomotic site. The duration of follow-up was significantly associated with the stage of RGC (P < 0.05). Patients diagnosed with early stage RGC such as stage Ⅰ-Ⅱ tended to have been followed up almost every second year. CONCLUSION: Meticulous follow-up examination and early detection of RGC might lead to a better prognosis. Based on the initial gastric disease and the procedure of reconstruction, an appropriate follow-up interval and programs might enable early detection of RGC. | Shuhei Komatsu Daisuke Ichikawa Kazuma Okamoto Daito Ikoma Masahiro Tsujiura Yukihisa Nishimura Yasutoshi Murayama Atsushi Shiozaki Hisashi Ikoma Yoshiaki Kuriu Masayoshi Nakanishi Hitoshi Fujiwara Toshiya Ochiai Yukihito Kokuba Eigo Otsuji | 2012 | World Journal of Gastroenterology2012，18，22： | 25 |
| 4 | Current role of ultrasound for the management of hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC)has a decisive influence on the prognosis of cirrhotic patients.Although α-fetoprotein(AFP)is a known and specific tumor maker for HCC,it is not suitable for the screening and surveillance of HCC because of its poor predictive value and low sensitivity.The use of imaging modalities is essential for the screening,diagnosis and treatment of HCC.Ultrasound(US)plays a major role among them,because it provides realtime and non-invasive observation by a simple and easy technique.In addition, US-guided needle puncture methods are frequently required for the diagnosis and/or treatment process of HCC.The development of digital technology has led to the detection of blood flow by color Doppler US, and the sensitivity for detecting tumor vascularity has shown remarkable improvement with the introduction of microbubble contrast agents.Moreover,near real- time 3-dimensional US images are now available.As for the treatment of HCC,high intensity focused ultrasound (HIFU)was developed as a novel technology that provides a transcutaneous ablation effect without needle puncture.These advancements in the US field have led to rapid progress in HCC management,and continuing advances are expected.This article reviews the current application of US for HCC in clinical practice. | Hitoshi Maruyama Masaharu Yoshikawa Osamu Yokosuka | 2008 | World Journal of Gastroenterology2008，14，11： | 24 |

| 6 | Portal hypertensive colopathy in patients with liver cirrhosis显示文摘AIM: In patients with liver cirrhosis and porlal hypertension, portal hypertensive colopathy is thought to be an important cause of lower gastrointestinal hemorrhage. In this study, we evaluated the prevalence of colonic mucosal changes in patients with liver cirrhosis and its clinical significance. METHODS: We evaluated the colonoscopic findings and liver function of 47 patients with liver cirrhosis over a 6-year period. The main cause of liver cirrhosis was post-viral hepatitis (68%) related to hepatitis B (6%) or C (62%)infection. All patients underwent upper gastrointestinal endoscopy to examine the presence of esophageal varices, cardiac varices, and congestive gastropathy, as well as a full colonoscopy to observe changes in colonic mucosa. Portal hypertensive colopathy was defined endoscopically in patients with vascular ectasia, redness, and blue vein. Vascular ectasia was classified into two types: type 1, solitary vascular ectasia; and type 2, diffuse vascular ectasia.RESULTS: Overall portal hypertensive colopathy was present in 31 patients (66%), including solitary vascular ectasia in 17 patients (36%), diffuse vascular ectasia in 20 patients (42%), redness in 10 patients (21%) and blue vein in 6 patients (12%). As the Child-Pugh class increased in severity, the prevalence of portal hypertensive colopathy rose. Child-Pugh class B and C were significantly associated with portal hypertensive colopathy. Portal hypertensive gastropathy, esophageal varices, ascites and hepatocellular carcinoma were not related to occurrence of portal hypertensive colopathy. Platelet count was significantly associated with portal hypertensive colopathy, but prothrombin time, serum albumin level, total bilirubin level and serum ALT level were not related to occurrence of portal hypertensive colopathy. CONCLUSION: As the Child-Pugh class worsens and platelet count decreases, the prevalence of portal hypertensive colopathy increases in patients with liver cirrhosis. A colonoscopic examination in patients with liver cirrhosis is indicated, especially those with worsening Child-Pugh class and/or decreasing platelet count, to prevent complications such as lower gastrointestinal bleeding. | Keiichi Ito Katsuya Shiraki Takahisa Sakai Hitoshi Yoshimura Takeshi Nakano | 2005 | World Journal of Gastroenterology2005，11，20： | 19 |
| 7 | Usefulness of noninvasive transient elastography for assessment of liver fibrosis stage in chronic hepatitis C显示文摘AIM:To evaluate the method of noninvasive transient elastography for assessment of histological stage of liver fibrosis in patients with chronic hepatitis C (CHC). METHODS: Two hundred and thirty-seven patients with CHC were included in this study. Liver biopsy was performed under ultrasonography on 217 of the patients, excluding twenty with clear clinical evidence of liver cirrhosis. Fifty subjects without liver disease were enrolled as a control group (stage 0). Twenty- five patients with sustained virological response (SVR) to interferon (IFN) therapy were also enrolled. These patients underwent liver biopsy before IFN therapy. Examination of liver stiffness (LS) was performed by elastography. RESULTS: Medians (50% levels) of LS were 4.1 (3.5-4.9), 6.3 (4.8-8.5), 8.8 (6.8-12.0), 14.6 (10.5-18.6), and 22.2 (15.4-28.0), respectively, in the fibrosis stages 0-4 (P < 0.001). LS was significantly correlated with four serum fibrosis markers. LS values in patients with SVR were 3.8 (3.5-5.6), 5.2 (4.4-6.8), 6.8 (6.1-7.6), and 6.1 (3.6-7.9), respectively, in the fibrosis stages 1-4. In all stages, LS for patients with SVR was significantly lower than that for patients who did not undergo IFN therapy. LS was significantly correlated with serum concentrations of hyaluronic acid, type Ⅳ collagen, type Ⅳ collagen 7S, and type Ⅲ procollagen N peptide. CONCLUSION: LS correlated well with the histologicalstage of fibrosis. Changes in liver fibrosis stage may thus be estimated noninvasively using transient elastography. | Tadashi Takeda Takahiro Yasuda Yuji Nakayama Mika Nakaya Megumi Kimura Mariko Yamashita Ayumi Sawada Koji Abo Setsuko Takeda Hiroki Sakaguchi Susumu Shiomi Hitoshi Asai Shuichi Seki | 2006 | World Journal of Gastroenterology2006，12，48： | 16 |

| 9 | Metabolism and Long-distance Translocationof Cytokinins显示文摘During plant development, distantly-located organs must communicate in order to adapt morphological and physiological features in response to environmental inputs. Among the recognized signaling molecules, a class of phytohormones known as the cytokinins functions as both local and long-distance regulatory signals for the coordination of plant development. This cytokinin-dependent communication system consists of orchestrated regulation of the metabolism, translocation, and signal transduction of this phytohormone class. Here, to gain insight into this elaborate signaling system, we summarize current models of biosynthesis, transmembrane transport, and long-distance translocation of cytokinins in higher plants. | Toru Kudo Takatoshi Kiba Hitoshi Sakakibara | 2010 | Journal of Integrative Plant Biology2010，52，1： | 16 |

| 11 | Deep-learning classifier with ultrawide-field fundus ophthalmoscopy for detecting branch retinal vein occlusion显示文摘AIM: To investigate and compare the efficacy of two machine-learning technologies with deep-learning(DL) and support vector machine(SVM) for the detection of branch retinal vein occlusion(BRVO) using ultrawide-field fundus images. METHODS: This study included 237 images from 236 patients with BRVO with a mean±standard deviation of age 66.3±10.6 y and 229 images from 176 non-BRVO healthy subjects with a mean age of 64.9±9.4 y. Training was conducted using a deep convolutional neural network using ultrawide-field fundus images to construct the DL model. The sensitivity, specificity, positive predictive value(PPV), negative predictive value(NPV) and area under the curve(AUC) were calculated to compare the diagnostic abilities of the DL and SVM models. RESULTS: For the DL model, the sensitivity, specificity, PPV, NPV and AUC for diagnosing BRVO was 94.0%(95%CI: 93.8%-98.8%), 97.0%(95%CI: 89.7%-96.4%), 96.5%(95%CI: 94.3%-98.7%), 93.2%(95%CI: 90.5%-96.0%) and 0.976(95%CI: 0.960-0.993), respectively. In contrast, for the SVM model, these values were 80.5%(95%CI: 77.8%-87.9%), 84.3%(95%CI: 75.8%-86.1%), 83.5%(95%CI: 78.4%-88.6%), 75.2%(95%CI: 72.1%-78.3%) and 0.857(95%CI: 0.811-0.903), respectively. The DL model outperformed the SVM model in all the aforementioned parameters(P<0.001). CONCLUSION: These results indicate that the combination of the DL model and ultrawide-field fundus ophthalmoscopy may distinguish between healthy and BRVO eyes with a high level of accuracy. The proposed combination may be used for automatically diagnosing BRVO in patients residing in remote areas lacking access to an ophthalmic medical center. | Daisuke Nagasato Hitoshi Tabuchi Hideharu Ohsugi Hiroki Masumoto Hiroki Enno Naofumi Ishitobi Tomoaki Sonobe Masahiro Kameoka Masanori Niki Yoshinori Mitamura | 2019 | International Journal of Ophthalmology(English edition)2019，12，1： | 16 |

| 13 | Optimal duration of the early and late recurrence of hepatocellular carcinoma after hepatectomy显示文摘AIM: To determine the best cut-off value between the early and late recurrence periods after the initial recurrence of hepatocellular carcinoma(HCC).METHODS: The clinical records of 404 patients who underwent macroscopic curative hepatectomy for HCC between 1980 and 2010 were retrospectively examined. We divided the 252 patients experienced a recurrence of HCC into two groups, the early and late recurrence groups using the 'minimum P-value' approach. Factors for early recurrence were investigated using all 404 patients, and factors related to late recurrence were investigated in the patients who were confirmed to be recurrence free at the end of the early recurrence period.RESULTS: For the 252 patients who experienced a recurrence, the optimal cut-off value for differentiating early and late recurrence based on the overall survival after initial recurrence was 17 mo(5-year overall survival after initial recurrence: 15.4% vs 36.3%, P = 0.000018). Cox proportional hazard analysis identified early recurrence(P = 0.003) as one of the independent prognostic factors associated with overall survival after initial recurrence. A logistic regression model showed that an alpha-fetoprotein level > 100 ng/m L(P < 0.001), multiple HCC(P < 0.001), serosal invasion(P = 0.031), and microvascular invasion(P = 0.012) were independent factors associated with early recurrence, whereas the only independent factor related to late recurrence was liver cirrhosis(P = 0.002).CONCLUSION: Seventeen months after hepatectomy is a useful cut-off value between early and late recurrence of HCC based on the prognosis and different etiologies. | Yusuke Yamamoto Hisashi Ikoma Ryo Morimura Hirotaka Konishi Yasutoshi Murayama Shuhei Komatsu Atsushi Shiozaki Yoshiaki Kuriu Takeshi Kubota Masayoshi Nakanishi Daisuke Ichikawa Hitoshi Fujiwara Kazuma Okamoto Chouhei Sakakura Toshiya Ochiai Eigo Otsuji | 2015 | World Journal of Gastroenterology2015，21，4： | 14 |
| 14 | Rifaximin ameliorates hepatic encephalopathy and endotoxemia without affecting the gut microbiome diversity显示文摘AIM To determine the efficacy of rifaximin for hepatic encephalopathy(HE) with the linkage of gut microbiome in decompensated cirrhotic patients.METHODS Twenty patients(12 men and 8 women; median age, 66.8 years; range, 46-81 years) with decompensated cirrhosis(Child-pugh score > 7) underwent cognitive neuropsychological testing, endotoxin analysis, and fecal microbiome assessment at baseline and after 4 wk of treatment with rifaximin 400 mg thrice a day. HE was determined by serum ammonia level and number connection test(NCT)-A. Changes in whole blood endotoxin activity(EA) was analyzed by endotoxinactivity assay. Fecal microbiome was assessed by 16 S ribosome RNA(rR NA) gene sequencing.RESULTS Treatment with rifaximin for 4 wk improved hyperammonemia(from 90.6 ± 23.9 μg/d L to 73.1 ± 33.1 μg/dL; P < 0.05) and time required for NCT(from 68.2 ± 17.4 s to 54.9 ± 20.3 s; P < 0.05) in patients who had higher levels at baseline. Endotoxin activity was reduced(from 0.43 ± 0.03 to 0.32 ± 0.09; P < 0.05) in direct correlation with decrease in serum ammonia levels(r = 0.5886, P < 0.05). No statistically significant differences were observed in the diversity estimator(Shannon diversity index) and major components of the gut microbiome between the baseline and after treatment groups(3.948 ± 0.548 at baseline vs 3.980 ± 0.968 after treatment; P = 0.544), but the relative abundances of genus Veillonella and Streptococcus were lowered.CONCLUSION Rifaximin significantly improved cognition and reduced endotoxin activity without significantly affecting the composition of the gut microbiome in patients with decompensated cirrhosis. | Kosuke Kaji Hiroaki Takaya Soichiro Saikawa Masanori Furukawa Shinya Sato Hideto Kawaratani Mitsuteru Kitade Kei Moriya Tadashi Namisaki Takemi Akahane Akira Mitoro Hitoshi Yoshiji | 2017 | World Journal of Gastroenterology2017，23，47： | 14 |
| 15 | Genistein inhibits invasive potential of human hepatocellular carcinoma by altering cell cycle, apoptosis, and angiogenesis显示文摘AIM: To study the in vitro and in vivo inhibitory effects of genistein on invasive potential of Bel 7402 hepatocellular carcinoma (HCC) cells and to explore the underlying mechanism.METHODS: Bel 7402 HCC cells were exposed to genistein. The invasive activity of tumor cells was assayed in transwell cell culture chamber. p125FAK expression and cell cycle were evaluated by a functional assay. Cell apoptosis analysis was performed with TUNEL method. In addition, bilateral subrenal capsule xenograft transplantation of HCC was performed in 10 nude mice.Genistein was injected and the invasion of HCC into the renal parenchyma was observed. Microvessels with immunohistochemical staining were detected.RESULTS: Genistein significantly inhibited the growth of Bel 7402 cells, the inhibitory rate of tumor cells was 26 -42%. The invasive potential of Bel 7402 cells in vitro was significantly inhibited, the inhibitory rate was 11-28%. Genistein caused G2/M cell cycle arrest, S phase decreased significantly. The occurrence of apoptosis in genistein group increased significantly. The expression of p125FAK in 5 μg/mL genistein group (15.26±0.16%)and 10 μg/mL genistein group (12.89±0.36%) was significantly lower than that in the control group (19.75± 1.12%,P<0.05). Tumor growth in genistein-treated nude mice was significantly retarded in comparison to control mice, the inhibitory rate of tumor growth was about 20%. Genistein also significantly inhibited the invasion of Bel 7402 cells into the renal parenchyma of nude mice with xenograft transplant. The positive unit value of microvessels in genistein-treated group (10.422±0.807)was significantly lower than that in control group (22.330 ± 5.696, P< 0.01).CONCLUSION: Genistein can effectively inhibit the invasive potential of Bel 7402 HCC cells by altering cell cycle, apoptosis and angiogenesis, inhibition of focal adhesion kinase may play a significant role in this process. | Yan Gu Chen-Fang Zhu Hitoshi Iwamoto Ji-Sheng Chen | 2005 | World Journal of Gastroenterology2005，11，41： | 13 |
| 16 | Risk factors to predict severe postoperative pancreatic fistula following gastrectomy for gastric cancer显示文摘AIM:To allow the identification of high-risk postoperative pancreatic fistula(POPF)patients with special reference to the International Study Group on Pancreatic Fistula(ISGPF)classification.METHODS:Between 1997 and 2010,1341 consecutive patients underwent gastrectomy for gastric cancer at the Department of Digestive Surgery,Kyoto Prefectural University of Medicine,Japan.Based on the preoperative diagnosis,total or distal gastrectomy and sufficient lymphadenectomy was performed,mainly according to the Japanese guidelines for the treatment of gastric cancer.Of these,35 patients(2.6%)were diagnosed with Grade B or C POPF according to the ISGPF classification and were treated intensively.The hospital records of these patients were reviewed retrospectively.RESULTS:Of 35 patients with severe POPF,17(49%)and 18(51%)patients were classified as Grade B and C POPF,respectively.From several clinical factors,the severity of POPF according to the ISGPF classification was significantly correlated with the duration of intensive POPF treatments(P=0.035).Regarding the clinical factors to distinguish extremely severe POPF,older patients(P=0.035,65 years≤vs<65 years old)and those with lower lymphocyte counts at the diagnosis of POPF(P=0.007,<1400/mm3vs 1400/mm3≤)were significantly correlated with Grade C POPF,and a low lymphocyte count was an independent risk factor by multivariate analysis[P=0.045,OR=10.45(95%CI:1.050-104.1)].CONCLUSION:Caution and intensive care are required for older POPF patients and those with lower lymphocyte counts at the diagnosis of POPF. | Shuhei Komatsu Daisuke Ichikawa Kingo Kashimoto Takeshi Kubota Kazuma Okamoto Hirotaka Konishi Atsushi Shiozaki Hitoshi Fujiwara Eigo Otsuji | 2013 | World Journal of Gastroenterology2013，19，46： | 13 |

| 18 | Dietary polyphenols and colorectal cancer risk:The Fukuoka colorectal cancer study显示文摘AIM:To investigate the associations between dietary intake of polyphenols and colorectal cancer. METHODS:The study subjects were derived from the Fukuoka colorectal cancer study, a community-based case-control study. The study subjects were 816 cases of colorectal cancer and 815 community-based controls. The consumption of 148 food items was assessed by a computer-assisted interview. We used the consumption of 97 food items to estimate dietary intakes of total, tea and coffee polyphenols. The Phenol-Explorer database was used for 92 food items. Of the 5 foods which were not listed in the Phenol-Explorer Database, polyphenol contents of 3 foods (sweet potatoes, satoimo and daikon) were based on a Japanese study and 2 foods (soybeans and fried potatoes) were estimated by ORAC-based polyphenol contents in the United States Department of Agriculture Database. Odds ratios (OR) and 95%CI of colorectal cancer risk according to quintile categories of intake were obtained by using logistic regression models with adjustment for age, sex, residential area, parental history of colorectal cancer, smoking, alcohol consumption, body mass index 10 years before, type of job, leisure-time physical activity and dietary intakes of calcium and n-3 polyunsaturated fatty acids.RESULTS:There was no measurable difference in total or tea polyphenol intake between cases and controls, but intake of coffee polyphenols was lower in cases than in controls. The multivariate-adjusted OR of colorectal cancer according to quintile categories of coffee polyphenols (from the first to top quintile) were 1.00 (referent), 0.81 (95%CI:0.60-1.10), 0.65 (95%CI:0.47-0.89), 0.65 (95%CI:0.46-0.89) and 0.82 (95%CI:0.60-1.10), respectively (P trend = 0.07). Similar, but less pronounced, decreases in the OR were also noted for the third and fourth quintiles of total polyphenol intake. Tea polyphenols and non-coffee polyphenols showed no association with colorectal cancer risk. The sitespecific analysis, based on 463 colon cancer cases and 340 rectal cancer cases, showed an inverse association between coffee polyphenols and colon cancer. The multivariate-adjusted OR of colon cancer for the first to top quintiles of coffee polyphenols were 1.00 (referent), 0.92 (95%CI:0.64-1.31), 0.75 (95%CI:0.52-1.08), 0.69 (95%CI:0.47-1.01), and 0.68 (95%CI:0.46-1.00), respectively (P trend = 0.02). Distal colon cancer showed a more evident inverse association with coffee polyphenols than proximal colon cancer. The association between coffee polyphenols and rectal cancer risk was U -shaped, with significant decreases in the OR at the second to fourth quintile categories. There was also a tendency that the OR of colon and rectal cancer decreased in the intermediate categories of total polyphenols. The decrease in the OR in the intermediate categories of total polyphenols was most pronounced for distal colon cancer. Intake of tea polyphenols was not associated with either colon or rectal cancer. The associations of coffee consumption with colorectal, colon and rectal cancers were almost the same as observed for coffee polyphenols. The trend of the association between coffee consumption and colorectal cancer was statistically significant. CONCLUSION:The present findings suggest a decreased risk of colorectal cancer associated with coffee consumption. | Zhen-Jie Wang Keizo Ohnaka Makiko Morita Kengo Toyomura Suminori Kono Takashi Ueki Masao Tanaka Yoshihiro Kakeji Yoshihiko Maehara Takeshi Okamura Koji Ikejiri Kitaroh Futami Takafumi Maekawa Yohichi Yasunami Kenji Takenaka Hitoshi Ichimiya Reiji Terasaka | 2013 | World Journal of Gastroenterology2013，19，17： | 12 |
| 19 | Spontaneous regression of hepatic inflammatory pseudotumor with primary biliary cirrhosis:Case report and literature review显示文摘肝的煽动性的假肿瘤(IPT ) 是煽动性的房间渗入的增殖的纤维组织描绘的稀罕良性的非肿瘤的损害。IPT 的准确病原学仍然保持不清楚。尽管有全身的煽动性的混乱的 IPT 的协会很好被建立了,有胆管炎的一种特殊关系是显然稀罕的。我们与主要胆汁性肝硬变(PBC ) 报导肝的 IPT 的自发的回归的一个案例。迄今为止,仅仅有 PBC 的 IPT 的二个案例被报导了。在我们的情况中,然而, IPT 在有效治疗导致的 PBC 的胆管炎的改进的功课期间发展了,不同于二个以前报导的案例。我们的案例显示 IPT 的发展也不联系到胆管炎或亢奋的 gamma-globulinemia 的活动,自从我们的案例被证实当胆汁的酶和免疫球蛋白比承认上的相应价值高得多时,没有 IPT 的放射线学的联盟者。我们有二个以前报导的案例的案例的比较建议与 PBC 发生的 IPT 不代表一样的疾病实体或是为 PBC 的一个旁观者。 | Hiroshi Koide Ken Sato Toshio Fukusato Kenji Kashiwabara Noriaki Sunaga Takafumi Tsuchiya Saeko Morino Naondo Sohara Satoru Kakizaki Hitoshi Takagi Masatomo Mori | 2006 | World Journal of Gastroenterology2006，12，10： | 12 |
| 20 | Decreased phagocytic activity of Kupffer cells in a rat nonalcoholic steatohepatitis model显示文摘AIM: To investigate Kupffer cell dynamics and phagocytic activity,using a rat nonalcoholic steatohepatitis (NASH) model. METHODS: Male F344 rats were fed either a control diet or a choline-deficient L-amino acid-defined (CDAA) diet,followed by contrast enhanced ultrasonography (CEUS) using Levovist. The uptake of latex beads by the Kupffer cells was determined by fluorescent microscopy. The status of the Kupffer cells was compared between the two groups,using the immunohistochemical staining technique. RESULTS: After 4 or more wk of the CDAA diet,CEUS examination revealed a decrease in the signal intensity,20 min after intravenous Levovist. Fluorescent microscopic examination showed that the uptake of latex beads by the Kupffer cells was reduced at week 1 and 2 in the study group,compared with the controls,with no further reduction after 3 wk. Immunohistochemical staining revealed no significant difference in the Kupffer cell counts between the control group and the CDAA group. CONCLUSION: CEUS examination using Levovist demonstrated reduced contrast effect and phagocytic activity in the liver parenchymal phase,although the Kupffer cell numbers were unchanged,indicating reduced phagocytic function of the Kupffer cells in the rat NASH model. We believe that CEUS examination using Levovist is a useful screening modality,which can detect NASH in fatty liver patients. | Tatsuhiro Tsujimoto Hideto Kawaratani Toshiyuki Kitazawa Toshiko Hirai Hajime Ohishi Mitsuteru Kitade Hitoshi Yoshiji Masahito Uemura Hiroshi Fukui | 2008 | World Journal of Gastroenterology2008，14，39： | 12 |
