| 1 | Portal vein thrombosis in liver cirrhosis显示文摘Portal vein thrombosis(PVT) is considered to be a frequent complication of liver cirrhosis. However, unlike PVT in patients without cirrhosis, very few data are available on the natural history and management of PVT in cirrhosis, despite its association with potentially life-threatening conditions, such as gastroesophageal bleeding and acute intestinal ischemia. Moreover, no consensus regarding PVT in cirrhosis exists. Suggested causes of PVT in cirrhosis include reduced portal blood flow velocity, multiple congenital or acquired thrombophilic factors, inherited or acquired conditions, and derangement of liver architecture. However, the understanding of PVT in cirrhosis is incomplete. In addition, information on the management of PVT in cirrhosis is inadequate. The aims of this review are to:(1) assemble data on the physiopathological mechanism, clinical findings, diagnosis and management of PVT in cirrhosis;(2) describe the principal factors most frequently involved in PVT development; and(3) summarize the recent knowledge concerning diagnostic and therapeutic procedures. | Nao Kinjo Hirofumi Kawanaka Tomohiko Akahoshi Yoshi-hiro Matsumoto Masahiro Kamori Yoshihiro Nagao Naotaka Hashimoto Hideo Uehara Morimasa Tomikawa Ken Shirabe Yoshihiko Maehara | 2014 | World Journal of Hepatology2014，6，2： | 38 |
| 2 | Anti-inflammatory activity of probiotic Bifidobacterium: Enhancement of IL-10 production in peripheral blood mononuclear cells from ulcerative colitis patients and inhibition of IL-8 secretion in HT-29 cells显示文摘AIM: To determine the anti-inflammatory activity of probiotic Bifidobacteria in Bifidobacteria-fermented milk (BFM) which is effective against active ulcerative colitis (UC) and exacerbations of UC, and to explore the immunoregulatory mechanisms. METHODS: Peripheral blood mononuclear cells (PBMNC) from UC patients or HT-29 cells were co-cultured with heat-killed probiotic bacteria or culture supernatant of Bifidobacterium breve strain Yakult (BbrY) or Bifidobacterium bifidum strain Yakult (BbiY) to estimate the amount of IL-10 or IL-8 secreted. RESULTS: Both strains of probiotic Bifidobacteria contained in the BFM induced IL-10 production in PBMNC from UC patients, though BbrY was more effective than BbiY. Conditioned medium (CM) and DNA of both strains inhibited IL-8 secretion in HT-29 cells stimulated with TNF-α, whereas no such effect was observed with heat- killed bacteria. The inhibitory effect of CM derived from BbiY was greater than that of CM derived from BbrY. DNAs of the two strains had a comparable inhibitory activity against the secretion of IL-8. CM of BbiY induced a repression of IL-8 gene expression with a higher expression of IκB-ζ mRNA 4 h after culture of HT-29 cells compared to that in the absence of CM.CONCLUSION: Probiotic Bifidobacterium strains in BFM enhance IL-10 production in PBMNC and inhibit IL-8 secretion in intestinal epithelial cells, suggesting that BFM has anti-inflammatory effects against ulcerative colitis. | Akemi Imaoka Tatsuichiro Shima Kimitoshi Kato Shigeaki Mizuno Toshiki Uehara Satoshi Matsumoto Hiromi Setoyama Taeko Hara Yoshinori Umesaki | 2008 | World Journal of Gastroenterology2008，14，16： | 37 |
| 3 | High-density lipoprotein and atherosclerosis: Roles of lipid transporters显示文摘Various previous studies have found a negative cor-relation between the risk of cardiovascular events and serum high-density lipoprotein(HDL) cholesterol levels. The reverse cholesterol transport, a pathway of choles-terol from peripheral tissue to liver which has several potent antiatherogenic properties. For instance, the particles of HDL mediate to transport cholesterol from cells in arterial tissues, particularly from atherosclerotic plaques, to the liver. Both ATP-binding cassette trans-porters(ABC) A1 and ABCG1 are membrane cholesterol transporters and have been implicated in mediating cholesterol effluxes from cells in the presence of HDL and apolipoprotein A-I, a major protein constituent of HDL. Previous studies demonstrated that ABCA1 and ABCG1 or the interaction between ABCA1 and ABCG1 exerted antiatherosclerotic effects. As a therapeutic approach for increasing HDL cholesterol levels, much focus has been placed on increasing HDL cholesterol levels as well as enhancing HDL biochemical functions. HDL therapies that use injections of reconstituted HDL, apoA-I mimetics, or full-length apoA-I have shown dramatic effectiveness. In particular, a novel apoA-I mi-metic peptide, Fukuoka University ApoA-I Mimetic Pep-tide, effectively removes cholesterol via specific ABCA1 and other transporters, such as ABCG1, and has an an-tiatherosclerotic effect by enhancing the biological func-tions of HDL without changing circulating HDL choles-terol levels. Thus, HDL-targeting therapy has significant atheroprotective potential, as it uses lipid transporter-targeting agents, and may prove to be a therapeutic tool for atherosclerotic cardiovascular diseases. | Yoshinari Uehara Keijiro Saku | 2014 | World Journal of Cardiology2014，6，10： | 10 |

| 5 | Advanced hepatocellular carcinoma responds to MK615, a compound extract from the Japanese apricot “Prunus mume ”显示文摘MK615, a compound extracted from the Japanese apricot 'Prunus mume ' has been reported to have in vitro anti-tumor activities against several cancer cell lines,including hepatocellular carcinoma(HCC). However, the clinical effects and feasibility of administering MK615for patients with HCC were unknown. We experienced a case with advanced HCC for which MK615 was effective against both lymph node and pulmonary metastases. A 60-year-old female underwent surgical resection of a 9 cm HCC in the right lobe. The pathological diagnosis was moderately differentiated HCC with vascular invasion. The HCC recurred in the liver 8 mo after the surgery. Radiofrequency ablation and transarterial infusion chemotherapy were performed, but the recurrence was not controlled. One year after the intrahepatic recurrence, pulmonary and lymph metastasis appeared.Sorafenib was administered, but was not effective.Then, MK615 was administered as a final alternative therapy after informed consent was obtained from the patient. Three months later, her alpha-fetoprotein level decrease and both the lymph node and pulmonary metastases decreased in size. The patient has survived for more than 17 mo after the MK615 administration, and was in good condition. Although further investigations are necessary to clarify its safety and efficacy in humans, MK615 may be useful for the treatment of HCC,without serious adverse effects. | Takashi Hoshino Hitoshi Takagi Atsushi Naganuma Eri Koitabashi Sanae Uehara Naomi Sakamoto Tomohiro Kudo Ken Sato Satoru Kakizaki | 2013 | World Journal of Hepatology2013，5，10： | 7 |

| 7 | Immunological effect of local ablation combined with immunotherapy on solid malignancies显示文摘Recent comprehensive investigations clarified that immune microenvironment surrounding tumor cells are deeply involved in tumor progression,metastasis,and response to treatment.Furthermore,several immunotherapeutic trials have achieved successful results,and the immunotherapeutic agents are available in clinical practice.To enhance their demonstrated efficacy,combination of immunotherapy and ablation has begun to emerge.Local ablations have considerable advantages as an alternative therapeutic option,especially its minimal invasiveness.In addition,local ablations have shown immune-regulatory effect in preclinical and clinical studies.Although the corresponding mechanisms are still unclear,the local ablations combined with immunotherapy have been suggested in the treatment of several solid malignancies.This article aims to review the published data on the immune-regulatory effects of local ablations including stereotactic body radiotherapy,cryoablation,radiofrequency ablation,and high-intensityfocused ultrasound.We also discuss the value of local ablations combined with immunotherapy.Local ablations have the potential to improve future patient outcomes;however,the effectiveness and safety of local ablations combined with immunotherapy should be further investigated. | Yusuke Takahashi Noriyuki Matsutani Takashi Nakayama Hitoshi Dejima Hirofumi Uehara Masafumi Kawamura | 2017 | Chinese Journal of Cancer2017，36，6： | 6 |
| 8 | Evaluation of a multiplex PCR assay for detection of cytomegalovirus in stool samples from patients with ulcerative colitis显示文摘AIM: To evaluate a multiplex PCR assay for the detection of bacterial and viral enteropathogens in stool samples from patients with ulcerative colitis(UC). METHODS: We prospectively analyzed 300 individuals, including immunocompetent patients, immunocompromised patients, and patients with UC. Stool samples were collected from the recto-sigmoid region of the colon by endoscopy. The samples were qualitatively analyzed for bacterial and viral enteropathogens with a multiplex PCR assay using a Seeplex® Kit. Additional clinical and laboratory data were collected from the medical records. RESULTS: A multiplex PCR assay detected 397 pathogens(191 bacteria and 206 viruses) in 215 samples(71.7%). The most frequently detected bacteria were Escherichia coli H7, 85(28.3%); followed by Aeromonas spp., 43(14.3%); and Clostridium perfringens, 36(12.0%) samples. The most prevalent viruses were Epstein-Barr virus(EBV), 90(30.0%); followed by human herpes virus-6(HHV-6), 53(17.7%); and cytomegalovirus(CMV), 37(12.3%) samples. The prevalence rate of CMV infection was significantly higher in the immunocompromised group than in the immunocompetent group(P < 0.01). CMV infection was more common in patients with UC(26/71; 36.6%)than in the immunocompetent patients excluding UC(6/188; 3.2%)(P < 0.01). CMV infection was more prevalent in UC active patients(25/58; 43.1%) than in UC inactive patients(1/13; 7.7%)(P < 0.05). Among 4 groups which defined by the UC activity and immunosuppressive drugs, the prevalence rate of CMV infection was highest in the UC active patients with immunosuppressive drugs(19/34; 55.8%). EpsteinBarr virus(EBV) infection was more common in the immunocompromised patients excluding UC(18/41; 43.9%) than in the immunocompetent patients excluding UC(47/188; 25.0%)(P < 0.05). The simultaneous presence of CMV and EBV and/or HHV6 in UC active patients(14/58; 24.1%) was greater than in immunocompromised patients excluding UC(5/41; 12.2%)(P < 0.05). CONCLUSION: The multiplex PCR assay that was used to analyze the stool samples in this study may serve as a non-invasive approach that can be used to exclude the possibility of CMV infection in patients with active UC who are treated with immunosuppressive therapy. | Saifun Nahar Atsushi Iraha Akira Hokama Ayako Uehara Gretchen Parrott Tetsuya Ohira Masatoshi Kaida Tetsu Kinjo Takeshi Kinjo Tetsuo Hirata Nagisa Kinjo Jiro Fujita | 2015 | World Journal of Gastroenterology2015，21，44： | 4 |

| 13 | The leaf extract of Mallotus japonicus and its major active constituent, rutin,suppressed on melanin production in murine B16F1 melanoma显示文摘Objective: To find anti-melanogenesis materials used in whitening cosmetics.Methods: The ethanolic leaf extract of Mallotus japonicus(M. japonicus) having an anti-melanogenesis activity was separated by a sephadex LH-20 chromatography. Each fraction was measured for its tyrosinase inhibitory activity together with its polyphenol content using the Folin–Ciocalteu method. The anti-melanogenesis activity of the active fractions was determined by the melanin content in the murine B16F1 melanoma. The active fractions were put together due to similar constituents, and then separated by high performance liquid chromatography using a C-18 ODS column. The major antimelanogenesis compound was identified using1 H and13C-NMR and liquid chromatography-mass spectrometry.Results: The ethanolic leaf extract of M. japonicus showed an anti-tyrosinase activity with a high polyphenol content, resulting in suppression of melanin production in the B16F1 melanoma. The extract was separated and the active compound was identical as rutin based on the1 H,13C-NMR and liquid chromatography-mass spectrometry analysis data. In addition, the rutin treatment with cells reduced the melanin content in a concentration dependent manner without any cell toxicity. The leaf extract of M. japonicus containing rutin would be useful in whitening cosmetics for protection from UV-light exposure to be limiting the accumulation of melanin in skin.Conclusions: The leaf extract of M. japonicus and/or rutin isolated from the extract as a key whitening agent would be useful as a whitening cosmetic material for protecting against disorder skin due to melanin accumulation. | Junsei Taira Eito Tsuchida Masatsugu Uehara Natsuko Ohhama Wakana Ohmine Takayuki Ogi | 2015 | Asian Pacific Journal of Tropical Biomedicine2015，5，10： | 2 |

| 18 | Human β-defensin-3 induction in H pylori-infected gastric mucosal tissues显示文摘AIM: To examine human β-defensin-3 (hBD-3) expression in inflamed gastric mucosal tissues or MKN45 gastric cancer cells with or without H pylori infection for better understanding the innate immune response to H pylori. METHODS: We used reverse transcription-polymerase chain reactions and immunohistochemistry to examine hBD-3 expression in inflamed gastric mucosal tissues or MKN45 gastric cancer cells with or without H pylori. Effects of hBD-3 against H pylori were also evaluated. RESULTS: The mean mRNA expression of hBD-3 in H pylori -positive specimens was significantly higher than that in H pylori-negative specimens (P = 0.0002, Mann-Whitney). In addition, unlike uninfected samples, 8 of 15 (53.33%) infected mucosal samples expressed hBD-3 protein. H pylori dose-dependently induced mRNA expression of hBD-3 in MKN45 cells, an effect inhibited by adding anti-toll-like receptor (TLR)-4 antibody. HBD-3 protein completely inhibited H pylori growth. CONCLUSION: Our results suggest that like hBD-2, hBD-3 may be involved in the pathophysiology of H pylori-induced gastritis. | K Kawauchi A Yagihashi N Tsuji N Uehara D Furuya D Kobayashi N Watanabe | 2006 | World Journal of Gastroenterology2006，12，36： | 2 |
| 19 | Synchronous rectal and esophageal cancer treated with chemotherapy followed by two-stage resection显示文摘We report a case of 61-year-old male who had synchronous advanced rectal cancer involving the urinary bladder massively associated with multiple liver metastases, and esophageal cancer successfully treated by neoadjuvant chemotherapy followed by two-stage resection. Although complete resection of each of the lesions was considered possible by performing anterior pelvic exenteration, liver resection, and esophagectomy, it might be impossible for the patient to endure the stress of all of these operative procedures at once. Therefore, we planned to perform staged treatment with prioritizing consideration. First, we instituted chemotherapy with the FOLFOX(oxaliplatin + fluorouracil + leucovorin) plus cetuximab regimen, which could adequately control both rectal and esophageal cancer. After 6 cycles of chemotherapy, high anterior resection combined with cystoprostatectomy and lateral segmentectomy plus partial hepatectomy was performed followed by staged esophagectomy with three-field lymph node dissection. It was possible to use oxaliplatin and cetuximab safely as neoadjuvant therapy not only for advanced rectal cancer but for esophageal cancer, and it was effective. | Setsuo Utsunomiya Keisuke Uehara Takuya Kurimoto Ken Hirose Masahide Fukaya Yu Takahashi Yoshiro Taguchi Keita Itatsu Masato Nagino | 2013 | World Journal of Clinical Cases2013，1，2： | 2 |
| 20 | Non-invasive prediction of non-alcoholic steatohepatitis in Japanese patients with morbid obesity by artificial intelligence using rule extraction technology显示文摘AIM To construct a non-invasive prediction algorithm for predicting non-alcoholic steatohepatitis(NASH), we investigated Japanese morbidly obese patients using artificial intelligence with rule extraction technology.METHODS Consecutive patients who required bariatric surgery underwent a liver biopsy during the operation. Standard clinical, anthropometric, biochemical measurements were used as parameters to predict NASH and were analyzed using rule extraction technology. One hundred and two patients, including 79 NASH and 23 non-NASH patients were analyzed in order to create the predictionmodel, another cohort with 77 patients including 65 NASH and 12 non-NASH patients were analyzed to validate the algorithm.RESULTS Alanine aminotransferase, C-reactive protein, homeostasis model assessment insulin resistance, albumin were extracted as predictors of NASH using a recursive-rule extraction algorithm. When we adopted the extracted rules for the validation cohort using a highly accurate rule extraction algorithm, the predictive accuracy was 79.2%. The positive predictive value, negative predictive value,sensitivity and specificity were 88.9%, 35.7%, 86.2% and 41.7%, respectively.CONCLUSION We successfully generated a useful model for predicting NASH in Japanese morbidly obese patients based on their biochemical profile using a rule extraction algorithm. | Daisuke Uehara Yoichi Hayashi Yosuke Seki Satoru Kakizaki Norio Horiguchi Hiroki Tojima Yuichi Yamazaki Ken Sato Kazuki Yasuda Masanobu Yamada Toshio Uraoka Kazunori Kasama | 2018 | World Journal of Hepatology2018，10，12： | 2 |
