| 1 | Apoptosis and non-alcoholic fatty liver diseases显示文摘The number of patients with nonalcoholic fatty liver diseases(NAFLD) including nonalcoholic steatohepatitis(NASH), has been increasing. NASH causes cirrhosis and hepatocellular carcinoma(HCC) and is one of the most serious health problems in the world. The mechanism through which NASH progresses is still largely unknown. Activation of caspases, Bcl-2 family proteins, and c-Jun N-terminal kinase-induced hepatocyte apoptosis plays a role in the activation of NAFLD/NASH. Apoptotic hepatocytes stimulate immune cells and hepatic stellate cells toward the progression of fibrosis in the liver through the production of inflammasomes and cytokines. Abnormalities in glucose and lipid metabolism as well as microbiota accelerate these processes. The production of reactive oxygen species, oxidative stress, and endoplasmic reticulum stress is also involved. Cell death, including apoptosis, seems very important in the progression of NAFLD and NASH. Recently, inhibitors of apoptosis have been developed as drugs for the treatment of NASH and may prevent cirrhosis and HCC. Increased hepatocyte apoptosis may distinguish NASH from NAFLD, and the improvement of apoptosis could play a role in controlling the development of NASH. In this review, the association between apoptosis and NAFLD/NASH are discussed. This review could provide their knowledge, which plays a role in seeing the patients with NAFLD/NASH in daily clinical practice. | Tatsuo Kanda Shunichi Matsuoka Motomi Yamazaki Toshikatsu Shibata Kazushige Nirei Hiroshi Takahashi Tomohiro Kaneko Mariko Fujisawa Teruhisa Higuchi Hitomi Nakamura Naoki Matsumoto Hiroaki Yamagami Masahiro Ogawa Hiroo Imazu Kazumichi Kuroda Mitsuhiko Moriyama | 2018 | World Journal of Gastroenterology2018，24，25： | 32 |
| 2 | Chemical characteristics of size-resolved aerosols in winter in Beijing显示文摘Size-resolved aerosols were continuously collected by a Nano Sampler for 13 days at an urban site in Beijing during winter 2012 to measure the chemical composition of ambient aerosol particles. Data collected by the Nano Sampler and an ACSM(Aerodyne Aerosol Chemical Speciation Monitor) were compared. Between the data sets,similar trends and strong correlations were observed,demonstrating the validity of the Nano Sampler. PM10 and PM2.5concentrations during the measurement were 150.5 ± 96.0 μg/m3(mean ± standard variation)and 106.9 ± 71.6 μg/m3,respectively. The PM2.5/PM10 ratio was 0.70 ± 0.10,indicating that PM2.5dominated PM10. The aerosol size distributions showed that three size bins of 0.5–1,1–2.5 and 2.5–10 μm contributed 21.8%,23.3% and 26.0% to the total mass concentration(TMC),respectively. OM(organic matter) and SIA(secondary ionic aerosol,mainly SO42-,NO3-and NH4+) were major components of PM2.5. Secondary compounds(SIA and secondary organic carbon) accounted for half of TMC(about 49.8%) in PM2.5,and suggested that secondary aerosols significantly contributed to the serious particulate matter pollution observed in winter. Coal burning,biomass combustion,vehicle emissions and SIA were found to be the main sources of PM2.5. Mass concentrations of water-soluble ions and undetected materials,as well as their fractions in TMC,strikingly increased with deteriorating particle pollution conditions,while OM and EC(elemental carbon) exhibited different variations,with mass concentrations slightly increasing but fractions in TMC decreasing. | Kang Sun Yu Qu Qiong Wu Tingting Han Jianwei Gu Jingjing Zhao Yele Sun Qi Jiang Ziqi Gao Min Hu Yuanhang Zhang Keding Lu Stephan Nordmann Yafang Cheng Li Hou Hui Ge Masami Furuuchi Mitsuhiko Hata Xingang Liu | 2014 | Journal of Environmental Sciences2014，26，8： | 9 |
| 3 | Constipation, hard stools, fecal urgency, and incomplete evacuation, but not diarrhea is associated with diabetes and its related factors显示文摘AIM: To determine the bowel symptoms associated with diabetes and diabetes-related factors after excluding gastrointestinal(GI) organic diseases.METHODS: Participants were 4738(603 diabetic and 4135 non-diabetic) patients who underwent colonoscopy and completed a questionnaire. On the day of pre-colonoscopy, 9 symptoms(borborygmus, abdominal distension, increased flatus, constipation, diarrhea, loose stools, hard stools, fecal urgency, and incomplete evacuation) were prospectively evaluated on a 7-point Likert scale. The test-retest reliability of the bowel symptom scores from the baseline and second questionnaires was analyzed using kappa statistics. Associations between bowel symptom scores and diabetes or diabetes-related factors were analyzed by a rank-ordered logistic model adjusted for related confounders, and odds ratios(ORs) were estimated.RESULTS: In multivariate analysis, constipation [adjusted odds ratio(AOR) = 1.57, CI: 1.33-1.85, P < 0.01] and hard stools(AOR = 1.56, CI: 1.33-1.84, P < 0.01) were associated with diabetes, and fecal urgency(AOR = 1.16, CI: 0.99-1.37, P = 0.07) and incomplete evacuation(AOR = 1.16, CI: 1.00-1.36, P = 0.06) were marginally associated with diabetes. These symptoms remained associated even after excluding organic GI diseases on colonoscopy. Test-retest reliability of symptom score with a mean duration of 3.2 mo was good(mean kappa, 0.69). Associations of symptoms with diabetes-related factors were found; constipation with Hb A1 c ≥ 8.0%(AOR = 2.11, CI: 1.19-3.73), b o d y m a s s i n d e x( B M I) < 2 5( A O R = 2. 1 1, C I : 1.22-3.66), and insulin use(AOR = 1.90, CI: 1.08-3.36); hard stools with diabetes duration(AOR = 1.03, CI: 1.00-1.07); fecal urgency with BMI < 25(AOR = 1.73, CI: 1.00-2.98); and incomplete evacuation with BMI < 25(AOR = 2.60, CI: 1.52-4.43), serum creatinine level(AOR = 1.27, CI: 1.10-1.47), and insulin use(AOR = 1.92, CI: 1.09-3.38).CONCLUSION: Diabetes is associated with constipation, hard stools, fecal urgency, and incomplete evacuation, and poor glycemic control, duration, leanness, and nephropathy affect the risk of these symptoms. | Noriko Ihana-Sugiyama Naoyoshi Nagata Ritsuko Yamamoto-Honda Eiko Izawa Hiroshi Kajio Takuro Shimbo Masafumi Kakei Naomi Uemura Junichi Akiyama Mitsuhiko Noda | 2016 | World Journal of Gastroenterology2016，22，11： | 5 |
| 4 | Characteristics of nanoparticles emitted from burning of biomass fuels显示文摘The characteristics of the particles of the smoke that is emitted from the burning of biomass fuels were experimentally investigated using a laboratory-scale tube furnace and different types of biomass fuels:rubber wood,whole wood pellets and rice husks.Emitted amounts of particles,particle-bound polycyclic aromatic hydrocarbons(PAHs)and water-soluble organic carbon(WSOC)are discussed relative to the size of the emitted particles,ranging to as small as nano-size(<70 nm),and to the rate of heating rate during combustion.differential thermal analysis(DTA)and thermogravimetric analysis(TG)techniques were used to examine the effect of heating rate and biomass type on combustion behaviors relative to the characteristics of particle emissions.In the present study,more than 30%of the smoke particles from the burning of biomass fuel had a mass that fell within a range of<100 nm.Particles smaller than 0.43μm contributed greatly to the total levels of toxic PAHs and WSOC.The properties of these particles were influenced by the fuel component,the combustion conditions,and the particle size.Although TG–DTA results indicated that the heating rate in a range of 10–20°C did not show a significant effect on the combustion properties,there was a slight increase in the decomposition temperature as heating rate was increased.The nano-size particles had the smallest fraction of particle mass and particle-bound PAHs,but nonetheless these particles registered the largest fraction of particle-bound WSOC. | Mitsuhiko Hata Jiraporn Chomanee Thunyapat Thongyen Linfa Bao Surajit Tekasakul Perapong Tekasakul Yoshio Otani Masami Furuuchi | 2014 | Journal of Environmental Sciences2014，26，9： | 5 |
| 5 | Contrast-enhanced ultrasonographic findings of serum amyloid A-positive hepatocellular neoplasm: Does hepatocellular adenoma arise in cirrhotic liver?显示文摘Hepatocellular adenoma(HCA) was recently classified into four pathological subtypes. There have been few studies describing the findings of contrast-enhanced ultrasonography(CEUS) of each type. Our case concerns a 78-year-old man who had undergone routine medical check-ups for hepatitis C for 11 years. Abdominal ultrasonography showed a 28 mm, hypo-echoic mass in the segment 4 of the liver. His integrating amount of drinking was 670 kg convert into ethanol. CEUS with Sonazoid demonstrated mild uniform hypo-enhancement with inflow of microbubbles from the periphery of the tumor in the arterial phase, and heterogeneously hypo-enhancement in the post vascular phase. Because the mass increased in size within 3 mo, a well differentiated hepatocellular carcinoma was suspected, and hepatic resection was performed. Microscopic findings showed homogeneous cell proliferation with low grade atypia, infiltration of inflammatory cells, ductular reactions, fatty deposit in part, and sinusoidal dilation. Immunohistochemistry revealed geographic positive for serum amyloid A(SAA), focal positive for glutaminesynthetase, diffuse and strong positive for C-reactive protein, and positive for liver-type fatty acid binding protein. These pathological features corresponded to that of an inflammatory HCA. However, we could not make a clear diagnosis, because HCAs were defined as not to arise in cirrhotic liver. Finally, this tumor was diagnosed as a SAA positive hepatocellular neoplasm. | Mariko Kumagawa Naoki Matsumoto Yukinobu Watanabe Midori Hirayama Takao Miura Hiroshi Nakagawara Masahiro Ogawa Shunichi Matsuoka Mitsuhiko Moriyama Tadatoshi Takayama Masahiko Sugitani | 2016 | World Journal of Hepatology2016，8，26： | 4 |
| 6 | 人工全膝关节中多孔钽金属型和骨水泥型胫骨假体周围骨矿物质密度比较显示文摘背景:多孔钽金属近年来用作全膝关节置换的金属植入材料。其多孔性、低弹性模量和高摩擦性能可保证良好的生理负荷传导并保留假体周围的骨储备。但就我们所知,这种小梁金属(TrabecularMetal)胫骨假体对周围骨矿物质密度的影响未见文献报道。本文的目的是对使用非骨水泥的小梁金属胫骨假体和骨水泥型胫骨假体关节周围骨矿物质密度进行比较。方法:对使用小梁金属胫骨假体和使用骨水泥固定的钴铬钼合金胫骨假体各28个膝分别在术前2周、术后2周、术后6、12、18和24个月进行双能x线吸收光谱扫描,以评价假体周围骨矿物质密度。所有手术均由一名医师操作并采用髌旁内侧入路。结果:术前两组股骨颈、腕关节、腰椎椎体或膝关节的骨密度均无明显差异。术后两组的胫骨骨密度均下降。但术后24个月的胫骨侧位x线片显示小梁金属胫骨假体周围的骨密度减低明显小于骨水泥型胫骨假体组(平均值±标准差,-6.7%±22.9%与-36.8%+24.2%;p=0.002)。两组患者的膝关节学会(Knee Society)评分、膝关节活动度和腰椎椎体骨密度在术后24个月无明显差异。假体微动和假体周围骨折在两组膝关节中均未见到。结论:全膝关节置换术使用小梁金属胫骨假体的胫骨外侧平台的骨密度降低小于使用骨水泥型胫骨假体的膝关节。确定多孔钽金属胫骨假体用于全膝关节置换的长期临床疗效尚待进一步研究。 | Yukihide Minoda Akio Kobayashi Hiroyoshi Iwaki Mitsuhiko Ikebuchi Fumiaki Inori Kunio Takaoka 赵建宁(译) 包倪荣(译) | 2010 | 中华骨科杂志2010，30，6： | 4 |
| 7 | A case of asymptomatic intraductal papillary neoplasm of the bile duct without hepatolithiasis显示文摘A 65-year-old woman was found to have dilatation of the intrahepatic bile duct in the right anterior segment during a general health. Laboratory data were within normal ranges and no solid mass was detected in her abdominal computer tomography (CT) or nuclear magnetic resonance imaging (MRI). However, endoscopic retrograde cholangiopancreatography (ERCP) demonstrated an obstruction of the right bile duct. Intraoperative cholangiography showed stenosis of the intrahepatic bile duct in the anterior inferior segment (B5) and narrowness of the intrahepatic bile duct in the anterior superior segment (B8), so that we strongly suspected intrahepatic cholangiocarcinoma (ICC). Histologically, surgically resected liver specimens, without tumor mass by macroscopic observation, showed intraductal papillary proliferation with fibrovascular cores and intraductal spreading of carcinoma in situ throughout a considerable area, especially in bile ductules around the peripheral small portal area. Furthermore, the immunohistochemical profile of the tumor (MUC5AC+/CK7+) was compatible with an intraductal papillary neoplasm of the bile duct (IPN-B). Consequently, this case was diagnosed as IPN-B with spreading CIS, stageⅠ(pT1, pN0, P0, H1, M0). We report a case of IPN-B with interesting histopathologicalfindings and emphasize that cholangiography is especially helpful for the diagnosis of bile duct dilatation due to infiltration of carcinoma cells. | Junpei Hayashi Shyun-ichi Matsuoka Makiko Inami Shu Ohshiro Akiyasu Ishigami Hirotoshi Fujikawa Masahide Miyagawa Kenji Mimatsu Youichi Kuboi Hisao Kanou Takatsugu Oida Makiko Inami Shu Ohshiro Mitsuhiko Moriyama | 2008 | World Journal of Gastroenterology2008，14，10： | 4 |
| 8 | Study on Targeting and in vitro Anti-oxidation of Baicalin Solid Lipid Nanoparticles显示文摘Objective To prepare liver-targeted baicalin solid lipid nanoparticles(BSLNs) and to study their in vitro anti-oxidative activity.Methods BSLNs were prepared by emulsification ultrasonic dispersion method and characterized by transmission electron microscopy and laser particle size distribution;The tissue in vivo distribution was detected by pharmacokinetics;In vitro anti-superoxide dismutase(SOD) activity and reduction capacity of BSLNs were determined;The ability of removing hydroxyl radical was determined by phenanthroline-Fe2+ oxidation.Results The best prescription was baicalin-soybean lecithin-glyceryl monostearate-poloxamer 188(1:5:15:30);The encapsulation efficiency and drug loading were 84.7% and 5.65%,respectively,mean size of particles was(68.6 ± 8) nm,Zeta potential was 22.13 mV;The in vitro anti-oxidant results showed that BSLNs had a significant inhibitory effect on SOD and a strong reducing capacity as well as a removing hydroxide radical ability.The targeting rate of BSLNs was 6.931 for liver.Conclusion The results demonstrate that BSLNs could enhance the liver targeting ability and in vitro anti-oxidative activity significantly. | MIYAMURA Mitsuhiko YOKOTA Junko YOSHIOKA Saburo | 2012 | Chinese Herbal Medicines2012，4，4： | 4 |
| 9 | ApoE isoforms,treatment of diabetes and the risk of coronary heart disease显示文摘AIM:To analyze the risk of coronary heart disease in patients with type 2 diabetes mellitus(T2DM)receiving standard medical treatment.METHODS:We performed a retrospective chart analysis of 269 middle-aged patients(age 45-64 years,mean age,53.9±5.5 years)with T2DM and without atherosclerotic cardiovascular events who underwent typing to determine their apolipoprotein E(apoE)isoforms.The apoE isoforms were determined using isoelectric focusing,followed by immunoblotting.We retrospectively evaluated the charts of the 269 patients,recorded between their first visit to the hospital(the study's start point,between 1987 and 1992)and the occurrence of an atherosclerotic cardiovascular event(the study's endpoint)or January 2004,whichever came first.The age-adjusted mean values and the prevalences of covariates were calculated to compare the laboratory data among the apoE phenotypes.To investigate the association of risk factors with the incidence of coronary heart disease during the follow-up period,monovariate and multivariate Cox regression models were used.RESULTS:At enrollment,the mean serum low density lipoprotein(LDL)cholesterol levels were lowest(2.92± 0.89 mmol/L)among the subjects with apoE2(apoE2/2 or apoE2/3)and highest(3.52±0.77 mmol/L)among the subjects with apoE4(apoE3/4 or apoE4/4).No significant differences in mean age or the percentage of smokers were observed among the three groups.Furthermore,no significant differences were observed in the systolic and diastolic blood pressures,body mass index,HbA1c level or serum triglyceride levels among the three groups.There were 47 cases of coronary heart disease over 3285 person-years of follow-up.An age-adjusted multivariate Cox proportional model identified diabetic retinopathy(hazard ratio,2.38,95% CI:1.28-4.43,P=0.006),a high systolic blood pressure(hazard ratio,1.04,95%CI:1.02-1.06,P<0.001) and high HbA1c values(hazard ratio,1.19,95%CI:1.02-1.38,P=0.0029),but not the LDL cholesterol value at enrollment(hazard ratio,1.01,95%CI:0.97-1.05,P=0.77)nor the specific apoE isoform,as significant predictors of coronary heart disease.CONCLUSION:Under standard medical treatment of diabetes,including the control of LDL cholesterol levels,the apoE4 isoform was not associated with coronary heart disease among T2DM patients. | Hideki Ehara Ritsuko Yamamoto-Honda Hiroji Kitazato Yoshihiko Takahashi Shoji Kawazu Yasuo Akanuma Mitsuhiko Noda | 2012 | World Journal of Diabetes2012，3，3： | 3 |
| 10 | Direct-acting antiviral agents against hepatitis C virus and lipid metabolism显示文摘Hepatitis C virus(HCV) infection induces steatosis and is accompanied by multiple metabolic alterations including hyperuricemia, reversible hypocholesterolemia and insulin resistance. Total cholesterol, low-density lipoprotein-cholesterol and triglyceride levels are increased by peginterferon and ribavirin combination therapy when a sustained virologic response(SVR) is achieved in patients with HCV. Steatosis is significantly more common in patients with HCV genotype 3 but interferon-free regimens are not always effective for treating HCV genotype 3 infections. HCV infection increases fatty acid synthase levels, resulting in the accumulation of fatty acids in hepatocytes. Of note, low-density lipoprotein receptor, scavenger receptor class B type Ⅰ and Niemann-Pick C1-like 1 proteins are candidate receptors that may be involved in HCV. They are also required for the uptake of cholesterol from the external environment of hepatocytes. Among HCV-infected patients with or without human immunodeficiency virus infection, changes in serum lipid profiles are observed during interferon-free treatment and after the achievement of an SVR. It is evident that HCV affects cholesterol metabolism during interferon-free regimens. Although higher SVR rates were achieved with interferon-free treatment of HCV, special attention must also be paid to unexpected adverse events based on host metabolic changes including hyperlipidemia. | tatsuo kanda mitsuhiko moriyama | 2017 | World Journal of Gastroenterology2017，23，31： | 3 |
| 11 | Histopathology of type C liver disease for determining hepatocellular carcinoma risk factors显示文摘AIM:To evaluate the histopathological findings of type C liver disease to determine risk factors for development of hepatocellular carcinoma(HCC).METHODS:We studied 232 patients,who underwent liver biopsy for type C chronic liver disease between 1992 and 2009,with sustained virological response(SVR)after interferon therapy.The patients were divided into two groups according to the F stage 0+1+2 group(n = 182)and F3+4 group(n = 50).We prospectively observed and compared the incidence of HCC of the patients with SVR in the F0+1+2 and F3+4 groups.Then,the background factors and liver histopathological findings,including the degree of fibrosis,F stage,inflammation,necrosis,bile duct obstruction,fat deposition,and degree of irregular regeneration(IR)of hepatocytes,were correlated with the risk of developing HCC.RESULTS:HCC developed in three of 182(1.6%)patients in the F0+1+2 group,and four of 50(8.0%)in the F3+4 group.The cumulative incidence of HCC in the former group was found to be significantly lower than in the F3+4 group(log rank test P = 0.0224).The presence of atypical hepatocytes among IR of hepatocytes in the F3+4 group resulted in a higher cumulative incidence of HCC,and was significantly correlated with risk of HCC development(RR = 20.748,95%CI:1.335-322.5,P = 0.0303).CONCLUSION:Atypical hepatocytes among the histopathological findings of type C liver disease may be an important risk factor for HCC development along with progression of liver fibrosis. | Hiroshi Matsumura Kazushige Nirei Hitomi Nakamura Teruhisa Higuchi Yasuo Arakawa Masahiro Ogawa Naohide Tanaka Mitsuhiko Moriyama | 2013 | World Journal of Gastroenterology2013，19，30： | 3 |
| 12 | Association of primary biliary cirrhosis with idiopathic thrombocytopenic purpura显示文摘Although both primary biliary cirrhosis (PBC) and idiopathic thrombocytopenic purpura (ITP) are autoimmune diseases, the association of the 2 diseases is rare. Here, we report a case of ITP that developed during the follow-up of PBC in a 74-year- old man. The patient had been diagnosed with PBC 12 years previously, and had received treatment with ursodeoxycholic acid. The platelet count decreased from approximately 60 × 109/L to 8 × 109/L, and the association of decompensated liver cirrhosis (PBC) with ITP was diagnosed. Steroid and immune gamma globulin therapy were successful in increasing the platelet count. Interestingly, human leukocyte antigen genotyping detected the alleles DQB10601 and DRB10803, which are related to both PBC and ITP in Japanese patients. This case suggests common immunogenetic factors might be involved in the development of PBC and ITP. | Nobuyuki Toshikuni Ryumei Yamato Haruhiko Kobashi Ken Nishino Nobu Inada Ritsuko Sakanoue Mitsuhiko Suehiro Yoshinori Fujimura Gotaro Yamada | 2008 | World Journal of Gastroenterology2008，14，15： | 2 |

| 14 | STAT3 deficiency prevents hepatocarcinogenesis and promotes biliary proliferation in thioacetamide-induced liver injury显示文摘AIM To elucidate the role of STAT3 in hepatocarcinogenesis and biliary ductular proliferation following chronic liver injury. METHODS We investigated thioacetamide(TAA)-induced liver injury, compensatory hepatocyte proliferation, and hepatocellular carcinoma(HCC) development in hepatic STAT3-deficient mice. In addition, we evaluated TAAinduced biliary ductular proliferation and analyzed the activation of sex determining region Y-box9(SOX9) and Yes-associated protein(YAP), which regulate the transdifferentiation of hepatocytes to cholangiocytes.RESULTS Both compensatory hepatocyte proliferation and HCC formation were significantly decreased in hepatic STAT3-deficient mice as compared with control mice. STAT3 deficiency resulted in augmentation of hepatic necrosis and fibrosis. On the other hand, biliary ductular proliferation increased in hepatic STAT3-deficient livers as compared with control livers. SOX9 and YAP were upregulated in hepatic STAT3-deficient hepatocytes.CONCLUSION STAT3 may regulate hepatocyte proliferation as well as transdifferentiation into cholangiocytes and serve as a therapeutic target for HCC inhibition and biliary regeneration. | Mitsuhiko Abe Takafumi Yoshida Jun Akiba Yu Ikezono Fumitaka Wada Atsutaka Masuda Takahiko Sakaue Toshimitsu Tanaka Hideki Iwamoto Toru Nakamura Michio Sata Hironori Koga Akihiko Yoshimura Takuji Torimura | 2017 | World Journal of Gastroenterology2017，23，37： | 2 |
| 15 | Endoscopic resection for residual lesion of metastatic gastric cancer:A case report显示文摘BACKGROUND Chemotherapy is a standard strategy for stage IV gastric cancer patients.However, some cases cannot undergo conversion surgery because of their frailty,even if the patients had response to chemotherapy. For these patients, local tumor progression is a problem. We report here the case of a patient whose residual gastric cancer was resected through endoscopic submucosal dissection(ESD)after concomitant chemotherapy for metastatic gastric cancer.CASE SUMMARY An 85-year-old male complained of difficulty swallowing, and examination revealed gastric cancer with multiple liver metastases. Although he received concomitant chemotherapy, a residual tumor was observed in the primary lesion while the metastatic lesions disappeared completely. Conversion surgery was considered optional treatment; however, he could not undergo that because of advanced age and comorbidities. Thus, we performed ESD to treat the residual tumor. As a result, we resected the residual lesion completely. The patient has been alive for 29 mo since ESD, without recurrence.CONCLUSION We achieved local control using ESD, and these findings may provide therapeutic improvements both in local control and patient survival outcomes. | Kaori Hayashi Sho Suzuki Hisatomo Ikehara Hiroaki Okuno Akira Irie Mitsuru Esaki Chika Kusano Takuji Gotoda Mitsuhiko Moriyama | 2019 | World Journal of Clinical Cases2019，7，4： | 2 |
| 16 | Hepatitis C virus-associated hepatocellular carcinoma after sustained virologic response显示文摘The introduction of a direct-acting antiviral(DAA) for patients with hepatitis C virus(HCV) infection, could lead to higher sustained virologic response(SVR)rates with fewer adverse events, and it could shorten the treatment duration relative to the interferon era. Although most recent clinical studies have demonstrated that the occurrence rates of hepatocellular carcinoma(HCC) are decreased by SVR with both interferon-based and interferon-free-regimens, there are several reports about the unexpected observation of high rates of early tumor occurrence and recurrence in patients with HCV-related HCC undergoing interferon-free therapy despite SVR. Several mechanisms of HCC occurrence and rapid immunological changes, including cytokines and chemokines during and after DAA treatment, have also been reported. We focused on the possibilities that HCC occurs or recurs during and after DAA treatment, based on the reported clinical and basic studies. Further studies and observations will be needed to determine the short-term and long-term effects on hepatocarcinogenesis caused by the eradication of HCV with DAAs. New serum biomarkers and a follow-up system for HCV-patients with SVR should be established. | Reina Sasaki Tatsuo Kanda Naoya Kato Osamu Yokosuka Mitsuhiko Moriyama | 2018 | World Journal of Hepatology2018，10，12： | 2 |

| 19 | Emissions of particulate matter and associated polycyclic aromatic hydrocarbons from agricultural diesel engine fueled with degummed,deacidified mixed crude palm oil blends显示文摘Mixed crude palm oil(MCPO),the mixture of palm fiber oil and palm kernel oil,has become of great interest as a renewable energy source.It can be easily extracted from whole dried palm fruits.In the present work,the degummed,deacidified MCPO was blended in petroleum diesel at portions of 30% and 40% by volume and then tested in agricultural diesel engines for long term usage.The particulates from the exhaust of the engines were collected every 500 hr using a four-stage cascade air sampler.The 50% cut-off aerodynamic diameters for the first three stages were 10,2.5 and 1μm,while the last stage collected all particles smaller than 1μm.Sixteen particle bounded polycyclic aromatic hydrocarbons(PAHs) were analyzed using a high performance liquid chromatography.The results indicated that the size distribution of particulate matter was in the accumulation mode and the pattern of total PAHs associated with fine-particles(< 1μm) showed a dominance of larger molecular weight PAHs(4-6 aromatic rings),especially pyrene.The mass median diameter,PM and total PAH concentrations decreased when increasing the palm oil content,but increased when the running hours of the engine were increased.In addition,Commercial petroleum diesel(PB0) gave the highest value of carcinogenic potency equivalent(BaP eq) for all particle size ranges.As the palm oil was increased,the BaP eq decreased gradually.Therefore the degummed-deacidified MCPO blends are recommended for diesel substitute. | Khamphe Phoungthong Surajit Tekasakul Perapong Tekasakul Gumpon Prateepchaikul Naret Jindapetch Masami Furuuchi Mitsuhiko Hata | 2013 | Journal of Environmental Sciences2013，25，4： | 2 |
