1Portal 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 2014World Journal of Hepatology2014,6,2:38
2Matricellular proteins as possible biomarkers for early brain injury after aneurysmal subarachnoid hemorrhage显示文摘Aneurysmal subarachnoid hemorrhage remains devastating,and the most important determinant of poor outcome is early brain injury(EBI).In clinical settings,as a surrogate marker of EBI,loss of consciousness at ictus,poor initial clinical grades,and some radiographic findings are used,but these markers are somewhat subjective.Thus,it is imperative to find biomarkers of EBI that have beneficial prognostic and therapeutic implications.In our opinion,an ideal biomarker is a molecule that is implicated in the pathogenesis of both EBI and subsequently developing delayed cerebral ischemia(DCI),being a therapeutic target,and can be measured easily in the peripheral blood in an acute stage.A good candidate of such a biomarker is a matricellular protein,which is a secreted,inducible and multifunctional extracellular matrix protein.There are many kinds of matricellular proteins reported,but only tenascin-C,osteopontin,galectin-3 and periostin are reported relevant to EBI and DCI.Reliable biomarkers of EBI may stratify aneurysmal subarachnoid hemorrhage patients into categories of risk to develop DCI,and allow objective monitoring of the response to treatment for EBI and earlier diagnosis of DCI.This review emphasizes that further investigation of matricellular proteins as an avenue for biomarker discovery is warranted.Hidenori Suzuki Hirofumi Nishikawa Fumihiro Kawakita 2018Neural Regeneration Research2018,13,7:20
3Therapeutic efficacy of the Qing Dai in patients with intractable ulcerative colitis显示文摘Ulcerative colitis (UC) is a chronic inflammatory bowel disease that may become intractable when treated with conventional medications such as aminosalicylates, corticosteroids, and azathioprine. The herbal medicine Qing Dai has traditionally been used in Chinese medicine to treat UC patients, but there is a lack of published data on the efficacy of Qing Dai in UC treatment. We report several cases of patients with intractable UC who take Qing Dai in a retrospective observational study. Furthermore, we explore the mechanisms of action of Qing Dai. Nine patients with active UC who received conventional medications but wished to receive Qing Dai as an alternative medication were included in our analysis. The UC severity level was determined based on the clinical activity index (CAI). Additionally, 5 of the 9 patients were endoscopically evaluated according to the Matts grading system. Each patient received 2 g/d of Qing Dai orally and continued taking other medications for UC as prescribed. Electron spin resonance was applied to explore the mechanisms of action of Qing Dai. After 4 mo of treatment with Qing Dai, the CAI score decreased from 8.3 ± 2.4 to 2.4 ± 3.4 (mean ± SD; P < 0.001). Similarly, the endoscopic Matts grade decreased from 3.4 ± 0.5 to 2.2 ± 0.8 (P = 0.02). Six of 7 patients who were on prednisolone upon enrollment in the study were able to discontinue this corticosteroid. Electron spin resonance revealed that Qing Dai possesses strong hydroxyl radical scavenging activity. Qing Dai showed significant clinical and endoscopic efficacy in patients who failed to respond to conventional medications. Scavenging of hydroxyl radicals appears to be a potential mechanism through which Qing Dai acts, but the significance of the scavenging ability of Qing Dai with respect to the anti-inflammatory effect in UC patients warrants further investigation.Hideo Suzuki Tsuyoshi Kaneko Yuji Mizokami Toshiaki Narasaka Shinji Endo Hirofumi Matsui Akinori Yanaka Aki Hirayama Ichinosuke Hyodo 2013World Journal of Gastroenterology2013,19,17:19

6Differential diagnosis of benign and malignant branch duct intraductal papillary mucinous neoplasm using contrastenhanced endoscopic ultrasonography显示文摘AIM: To elucidate the role of contrast-enhanced endoscopic ultrasonography(CE-EUS) in the diagnosis of branch duct intraductal papillary mucinous neoplasm(BD-IPMN).METHODS: A total of 50 patients diagnosed with BDIPMN by computed tomography(CT) and endoscopic ultrasonography(EUS) at our institute were included in this study. CE-EUS was performed when mural lesions were detected by EUS. The diagnostic accuracy for identifying mural nodules(MNs) was evaluated by CT, EUS, and EUS combined with CE-EUS. In the patients who underwent resection, the accuracy of measuring MN height with each imaging modality was compared. The cut-off values to diagnose malignant BD-IPMNs based on MN height for each imaging modality were determined using receiver operating characteristic curve analysis.RESULTS: Fifteen patients were diagnosed with BD-IPMN with MNs and underwent resection. The remaining 35 patients were diagnosed with BD-IPMN without MNs and underwent follow-up monitoring. The pathological findings revealed 14 cases with MNs and one case without. The accuracy for diagnosing MNs was 92% using CT and 72% using EUS; the diagnostic accuracy increased to 98% when EUS and CE-EUS were combined. The accuracy for measuring MN height significantly improved when using CE-EUS compared with using CT or EUS(median measurement error value, CT: 3.3 mm vs CE-EUS: 0.6 mm, P < 0.05; EUS: 2.1 mm vs CE-EUS: 0.6 mm, P < 0.01). A cut-off value of 8.8 mm for MN height as measured by CE-EUS improved the accuracy of diagnosing malignant BDIPMN to 93%. CONCLUSION: Using CE-EUS to measure MN height provides a highly accurate method for differentiating benign from malignant BD-IPMN.Hirofumi Harima Seiji Kaino Shuhei Shinoda Michitaka Kawano Shigeyuki Suenaga Isao Sakaida 2015World Journal of Gastroenterology2015,21,20:12

8Cytokines in adipose-derived mesenchymal stem cells promote the healing of liver disease显示文摘Adipose-derived mesenchymal stem cells(ADSCs) are a treatment cell source for patients with chronic liver injury. ADSCs are characterized by being harvested from the patient's own subcutaneous adipose tissue, a high cell yield(i.e., reduced immune rejection response), accumulation at a disease nidus, suppression of excessive immune response, production of various growth factors and cytokines, angiogenic effects, antiapoptotic effects, and control of immune cells via cellcell interaction. We previously showed that conditioned medium of ADSCs promoted hepatocyte proliferation and improved the liver function in a mouse model of acute liver failure. Furthermore, as found by many other groups, the administration of ADSCs improved liver tissue fibrosis in a mouse model of liver cirrhosis. A comprehensive protein expression analysis by liquid chromatography with tandem mass spectrometry showed that the various cytokines and chemokines produced by ADSCs promote the healing of liver disease. In this review, we examine the ability of expressed protein components of ADSCs to promote healing in cell therapy for liver disease. Previous studies demonstrated that ADSCs are a treatment cell source for patients with chronic liver injury. This review describes the various cytokines and chemokines produced by ADSCs that promote the healing of liver disease.Saifun Nahar Yoshiki Nakashima Chika Miyagi-Shiohira Takao Kinjo Zensei Toyoda Naoya Kobayashi Issei Saitoh Masami Watanabe Hirofumi Noguchi Jiro Fujita 2018World Journal of Stem Cells2018,10,11:11

10Improvement of prognosis for unresectable biliary tract cancer显示文摘AIM:To evaluate the chemotherapeutic outcomes and confirm the recent improvement of prognosis for unresectable biliary tract cancer.METHODS:A total of 186 consecutive patients with unresectable biliary tract cancer,who had been treated with chemotherapy between 2000 and 2009 at five institutions in Japan,were retrospectively analyzed.These patients were divided into three groups based on the year beginning chemotherapy:Group A(2000-2003),Group B(2004-2006),and Group C(2007-2009).The data were fixed at the end of December 2011.Overall survival and time-to-progression were analyzed and compared chronologically.RESULTS:No patient characteristics were significantly different among the three groups.The gallbladder was involved in about half of the patients in each group,and metastatic biliary tract cancer was present in three quarters of the enrollees.In Group A,5-fluorouracilbased chemotherapies were primarily selected as firstline chemotherapy,and only 24% were treated with second-line chemotherapy.In Group B,gemcitabine or S-1 monotherapy was mainly introduced as firstline chemotherapy,and 51% of the patients who were refractory to first-line chemotherapy were treated with second-line chemotherapy mainly with monotherapy.In Group C,the combination therapy with gemcitabine and S-1 was mainly chosen as first-line chemotherapy,and 53% of the patients refractory to first-line chemotherapy were treated with second-line chemotherapy mainly with combination therapy.The median timeto-progressions were 4.4 mo,3.5 mo and 5.9 mo in Groups A,B and C,respectively(4.4 mo vs 3.5 mo vs 5.9 mo,P < 0.01).The median overall survivals were 7.1,7.3,and 11.7 mo in Groups A,B and C(7.1 mo vs 7.3 mo vs 11.7 mo,P = 0.03).Induction rates of all three drugs(gemcitabine,platinum analogs,and fluoropyrimidine) in Groups A,B and C were 4%,2% and 27%(4% vs 2% vs 27%,P < 0.01).CONCLUSION:The prognosis of unresectable biliary tract cancer has improved recently.Using three effective drugs(gemcitabine,platinum analogs,and fluoropyrimidine) may improve the prognosis of this cancer.Takashi Sasaki Hiroyuki Isayama Yousuke Nakai Naminatsu Takahara Naoki Sasahira Hirofumi Kogure Suguru Mizuno Hiroshi Yagioka Yukiko Ito Natsuyo Yamamoto Kenji Hirano Nobuo Toda Minoru Tada Masao Omata Kazuhiko Koike 2013World Journal of Gastroenterology2013,19,1:8
11Serum manganese superoxide dismutase and thioredoxin are potential prognostic markers for hepatitis C virus-related hepatocellular carcinoma显示文摘AIM:To evaluate the clinical significance of oxidative stress markers in patients with hepatitis C virus(HCV)related hepatocellular carcinoma(HCC).METHODS:Sixty-four consecutive patients who were admitted to Kagoshima University Medical and Dental Hospital were enrolled in this retrospective study.All patients had chronic liver disease(CLD) due to infection with HCV.Thirty patients with HCV-related HCC,34 with HCV-related CLD without HCC(non-HCC),and 20 healthy volunteers(HVs) were enrolled.Possible associations between serum manganese superoxide dismutase(MnSOD) and thioredoxin(TRX) levels and clinical parameters or patient prognosis were analyzed over a mean follow-up period of 31.7 mo.RESULTS:The serum MnSOD levels were significantly higher in patients with HCV-related HCC than in patients without HCC(P = 0.03) or HVs(P < 0.001).Similarly,serum TRX levels were also significantly higher in patients with HCV-related HCC than in patients without HCC(P = 0.04) or HVs(P < 0.01).However,serum levels of MnSOD and TRX were not correlated in patients with HCC.Among patients with HCC,the overall survival rate(OSR) was lower in patients with MnSOD levels ≥ 110 ng/mL than in patients with levels < 110 ng/mL(P = 0.01),and the OSR tended to be lower in patients with TRX levels < 80 ng/mL(P = 0.05).In addition,patient prognosis with HCC was poorest with serum MnSOD levels ≥ 110 ng/mL and serum TRX levels < 80 ng/mL.Furthermore,a multivariate analysis using a Cox proportional hazard model and serum levels of five factors(MnSOD,prothrombin time,serum albumin,serum α-fetoprotein(AFP),and serum des-γ-carboxy prothrombin) revealed that MnSOD levels ≥ 110 ng/mL(risk ratio:4.12,95% confidential interval:1.22-13.88,P = 0.02) and AFP levels ≥ 40 ng/mL(risk ratio:6.75;95% confidential interval:1.70-26.85,P < 0.01) were independent risk factors associated with a poor patient prognosis.CONCLUSION:Serum MnSOD and TRX levels are potential clinical biomarkers that predict patient prognosis in HCV-related HCC.Tsutomu Tamai Hirofumi Uto Yoichiro Takami Kouhei Oda Akiko Saishoji Masashi Hashiguchi Kotaro Kumagai Takeshi Kure Seiichi Mawatari Akihiro Moriuchi Makoto Oketani Akio Ido Hirohito Tsubouchi 2011World Journal of Gastroenterology2011,17,44:7

13Pancreatic islet transplantation显示文摘Type 1 diabetes mellitus is an autoimmune disease,which results in the permanent destruction of β-cells of the pancreatic islets of Langerhans.While exogenous insulin therapy has dramatically improved the quality of life,chronic diabetic complications develop in a substantial proportion of subjects and these complications generally progress and worsen over time.Although intensive insulin therapy has proven effective to delay and sometimes prevent the progression of complications such as nephropathy,neuropathy or retinopathy,it is difficult to achieve and maintain long term in most subjects.Reasons for this diff iculty include compliance issues and the increased risk of severe hypoglycemic episodes,which are generally associated with intensification of exogenous insulin therapy.Clinical studies have shown that transplantation of pancreas or purified pancreatic islets can support glucose homeostasis in type 1 diabetic patients.Islet transplantation carries the special advantages of being less invasive and resulting in fewer complications compared with the traditional pancreas or pancreas-kidney transplantation.However,islet transplantation efforts have limitations including the short supply of donor pancreata,the paucity of experienced islet isolation teams,side effects of immunosuppressants and poor long-term results.The purpose of this article is to review recent progress in clinical islet transplantation for the treatment of diabetes.Hirofumi Noguchi 2009World Journal of Gastrointestinal Surgery2009,1,1:7

15Significance of functional hepatic resection rate calculated using 3D CT/^(99m)Tc-galactosyl human serum albumin singlephoton emission computed tomography fusion imaging显示文摘AIM: To evaluate the usefulness of the functional hepatic resection rate(FHRR) calculated using 3D computed tomography(CT)/^(99m)Tc-galactosyl-human serum albumin(GSA) single-photon emission computed tomography(SPECT) fusion imaging for surgical decision making. METHODS: We enrolled 57 patients who underwent bi- or trisectionectomy at our institution between October 2013 and March 2015. Of these, 26 patients presented with hepatocellular carcinoma, 12 with hilar cholangiocarcinoma, six with intrahepatic cholangiocarcinoma, four with liver metastasis, and nine with other diseases. All patients preoperatively underwent three-phase dynamic multidetector CT and ^(99m)Tc-GSA scintigraphy. We compared the parenchymal hepatic resection rate(PHRR) with the FHRR, which was defined as the resection volume counts per total liver volume counts on 3D CT/^(99m)Tc-GSA SPECT fusion images.RESULTS: In total, 50 patients underwent bisectionectomy and seven underwent trisectionectomy.Biliary reconstruction was performed in 15 patients, including hepatopancreatoduodenectomy in two. FHRR and PHRR were 38.6 ± 19.9 and 44.5 ± 16.0, respectively; FHRR was strongly correlated with PHRR. The regression coefficient for FHRR on PHRR was 1.16(P < 0.0001). The ratio of FHRR to PHRR for patients with preoperative therapies(transcatheter arterial chemoembolization, radiation, radiofrequency ablation, etc.), large tumors with a volume of > 1000 m L, and/or macroscopic vascular invasion was significantly smaller than that for patients without these factors(0.73 ± 0.19 vs 0.82 ± 0.18, P < 0.05). Postoperative hyperbilirubinemia was observed in six patients. Major morbidities(Clavien-Dindo grade ≥ 3) occurred in 17 patients(29.8%). There was no case of surgeryrelated death.CONCLUSION: Our results suggest that FHRR is an important deciding factor for major hepatectomy, because FHRR and PHRR may be discrepant owing to insufficient hepatic inflow and congestion in patients with preoperative therapies, macroscopic vascular invasion, and/or a tumor volume of > 1000 m L.Yosuke Tsuruga Toshiya Kamiyama Hirofumi Kamachi Shingo Shimada Kenji Wakayama Tatsuya Orimo Tatsuhiko Kakisaka Hideki Yokoo Akinobu Taketomi 2016World Journal of Gastroenterology2016,22,17:6
16Effect of high-pressure homogenization on stability of emulsions containing zein and pectin显示文摘The aim of this study was to investigate the effect of high-pressure homogenization on the droplet size and physical stability of different formulations of pectin–zein stabilized rice bran oil emulsions. The obtained emulsions, both before and after passing through highpressure homogenizer, were subjected to stability test under environmental stress conditions,that is, temperature cycling at 4 °C/40 °C for 6 cycles and centrifugal test at 3000 rpm for 10 min. Applying high-pressure homogenization after mechanical homogenization caused only a small additional decrease in emulsion droplet size. The droplet size of emulsions was influenced by the type of pectin used;emulsions using high methoxy pectin(HMP) were smaller than that using low methoxy pectin(LMP). This is due to a greater emulsifying property of HMP than LMP. The emulsions stabilized by HMP–zein showed good physical stability with lower percent creaming index than those using LMP, both before and after passing through high-pressure homogenizer. The stability of emulsions after passing through high-pressure homogenizer was slightly higher when using higher zein concentration, resulting from stronger pectin–zein complexes that could rearrange and adsorb onto the emulsion droplets.Maneerat Juttulapa Suchada Piriyaprasarth Hirofumi Takeuchi Pornsak Sriamornsak 2017Asian Journal of Pharmaceutical Sciences2017,12,1:6
17Immunological 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 2017Chinese Journal of Cancer2017,36,6:6
18Retrocaval liver lifting maneuver and modifications of total hepatic vascular exclusion for liver tumor resection显示文摘AIM: To evaluate the efficacy of technical modifications of total hepatic vascular exclusion(THVE) for hepatectomy involving inferior vena cava(IVC).METHODS: Of 301 patients who underwent hepatectomy during the immediate previous 5-year period, 8(2.7%) required THVE or modified methods of IVC cross-clamping for resection of liver tumors with massive involvement of the IVC. Seven of the patients had diagnosis of colorectal liver metastases and 1 had diagnosis of hepatocellular carcinoma. All tumors involved the IVC, and THVE was unavoidable for combined resection of the IVC in all 8 of the patients. Technical modifications of THVE were applied to minimize the extent and duration of vascular occlusion, thereby reducing the risk of damage.RESULTS: Broad dissection of the space behind the IVC coupled with lifting up of the liver from the retrocaval space was effective for controlling bleeding around the IVC before and during THVE. The procedures facilitate modification of the positioning of the cranial IVC cross-clamp. Switching the cranial IVC cross-clamp from supra- to retrohepatic IVC or to the confluence of hepatic vein decreased duration of the THVE while restoring hepatic blood flow or systemic circulation via the IVC. Oblique cranial IVC cross-clamping avoided ischemia of the remnant hemi-liver. With these technicalmodifications, the mean duration of THVE was 13.4 ± 8.4 min, which was extremely shorter than that previously reported in the literature. Recovery of liver function was smooth and uneventful for all 8 patients. There was no case of mortality, re-operation, or severe complication(i.e., Clavien-Dindo grade of Ⅲ or more).CONCLUSION: The retrocaval liver lifting maneuver and modifications of cranial cross-clamping were useful for minimizing duration of THVE.Saiho Ko Yuuki Kirihatayfa Yayoi Matsumoto Tadataka Takagi Masanori Matsusaka Tomohide Mukogawa Hirofumi Ishikawa Akihiko Watanabe 2016World Journal of Hepatology2016,8,8:5
