| 1 | Nonalcoholic fatty liver disease is a novel predictor of cardiovascular disease显示文摘AIM:To clarify whether nonalcoholic fatty liver disease(NAFLD)increases the risk of cardiovascular disease.METHODS:We carried out a prospective observational study with a total of 1637 apparently healthy Japanese men and women who were recruited from a health check-up program.NAFLD was diagnosed by abdominal ultrasonography.The metabolic syndrome(MS)was defined according to the modified National Cholesterol Education Program(NCEP)ATP Ⅲ criteria.Five years after the baseline evaluations,the incidence of cardiovascular disease was assessed by a self-administered questionnaire.RESULTS:Among 1221 participants available for outcome analyses,the incidence of cardiovascular disease was higher in 231 subjects with NAFLD at baseline(5 coronary heart disease,6 ischemic stroke,and 1 cerebral hemorrhage)than 990 subjects without NAFLD(3 coronary heart disease,6 ischemic stroke,and 1 cerebral hemorrhage).Multivariate analyses indicated that NAFLD was a predictor of cardiovascular disease independent of conventional risk factors(odds ratio 4.12,95% CI,1.58 to 10.75,P = 0.004).MS was alsoindependently associated with cardiovascular events.But simultaneous inclusion of NAFLD and MS in a multivariate model revealed that NAFLD but not MS retained a statistically significant correlation with cardiovascular disease.CONCLUSION:Although both of them were predictors of cardiovascular disease,NAFLD but not MS retained a statistically significant correlation with cardiovascular disease in a multivariate model.NAFLD is a strong predictor of cardiovascular disease and may play a central role in the cardiovascular risk of MS. | Masahide Hamaguchi Takao Kojima Noriyuki Takeda Chisato Nagata Jun Takeda Hiroshi Sarui Yutaka Kawahito Naohisa Yoshida Atsushi Suetsugu Takahiro Kato Junichi Okuda Kazunori Ida Toshikazu Yoshikawa | 2007 | World Journal of Gastroenterology2007，13，10： | 55 |
| 2 | Association of glypican-3 expression with growth signaling molecules in hepatocellular carcinoma显示文摘AIM:To clarify the association of glypican-3(GPC3)expression with Wnt and other growth signaling molecules in hepatocellular carcinoma(HCC). METHODS:Expression of GPC3,Wnt,matrix metalloproteinases(MMPs),sulfatase(SULF)1,SULF2,and other growth signaling molecules was analyzed in HCC cell lines and tissue samples by real-time reverse transcriptionpolymerase chain reaction,immunoblotting,and/or immunostaining.Expression of various genes in GPC3 siRNA-transfected HCC cells was analyzed. RESULTS:GPC3 was overexpressed in most HCCs at mRNA and protein levels and its serum levels weresignificantly higher in patients with HCC than in non- HCC subjects(P<0.05).Altered expressions of various MMPs and growth signaling molecules,some of which were correlated with GPC3 expression,were observed in HCCs.Down-regulation of GPC3 expression by siRNA in GPC3-overexpressing HCC cell lines resulted in a significant decrease in expressions of MMP2,MMP14,fibroblast growth factor receptor 1,insulin-like growth factor 1 receptor.GPC3 expression was significantly correlated with nuclear/cytoplasmic localization ofβ-catenin. CONCLUSION:These results suggest that GPC3,in conjunction with MMPs and growth signaling molecules, might play an important role in the progression of HCC. | Noriyuki Akutsu Hiroyuki Yamamoto Shigeru Sasaki Hiroaki Taniguchi Yoshiaki Arimura Kohzoh Imai Yasuhisa Shinomura | 2010 | World Journal of Gastroenterology2010，16，28： | 20 |
| 3 | Transcriptional silencing of Dickkopf gene family by CpG island hypermethylation in human gastrointestinal cancer显示文摘AIM: To clarify alterations of Dickkopfs (Dkks) and Kremen2 (Krm2) in gastrointestinal cancer. METHODS: We investigated the expression profiles and epigenetic alterations of Dkks and Krm2 genes in gastrointestinal cancer using RT-PCR, tissue microarray analysis, and methylation specific PCR (MSP). Cancer cells were treated with the demethylating agent and/or histone deacetylase inhibitor. WST-8 assays and in vitro invasion assays after treatment with specific siRNA for those genes were performed. RESULTS: Dkks and Krm2 expression levels were reduced in a certain subset of the gastrointestinal cancer cell lines and cancer tissues. This was correlated with promoter hypermethylation. There were significant correlations between Dkks over-expression levels and beta-catenin over-expression in colorectal cancer. In colorectal cancers with beta-catenin over-expression, Dkk-1 expression levels were significantly lower in those with lymph node metastases than in those without. Down-regulation of Dkks expression by siRNA resulted in a significant increase in cancer cell growth and invasiveness in vitro.CONCLUSION: Down-regulation of the Dkks associated to promoter hypermethylation appears to be frequently involved in gastrointestinal tumorigenesis. | Tadateru Maehata Hiroaki Taniguchi Hiroyuki Yamamoto Katsuhiko Nosho Yasushi Adachi Nobuki Miyamoto Chie Miyamoto Noriyuki Akutsu Satoshi Yamaoka Fumio Itoh | 2008 | World Journal of Gastroenterology2008，14，17： | 19 |
| 4 | Aging is a risk factor of nonalcoholic fatty liver disease in premenopausal women显示文摘AIM: To clarify the relationship between age, menopause, and nonalcoholic fatty liver disease (NAFLD) in women. METHODS: We conducted a follow-up study on non-alcoholic fatty liver disease by using abdominal ultrasonography, and investigated the relationship of age and menopause with the development of NAFLD in women. We followed 1829 women and 2572 men (response rate, 86%) selected in 2001 to represent the non-institutionalized adult population of Gifu, Japan. Data collected included self-reported medical history, lifestyle factors, and menopausal status. The postmenopausal state was defined as beginning 1 year after the cessation of menses. We diagnosed NAFLD with the aid of abdominal ultrasonography by using diagnostic criteria describedRESULTS: The prevalence of NAFLD in women increases with age, but does not alter with age in men. Furthermore, the prevalence of NAFLD in premenopausal women (6%) was lower than that in men (24%) and in postmenopausal women (15%). The associations of the postmenopausal state and hormone replacement therapy with NAFLD were statistically significant in a univariate logistic regression model. At the follow-up examination, 67 women (5%) were newly diagnosed with NAFLD. The incidence of NAFLD was 3.5% (28/802) in premenopausal women, 7.5% (4/53) in menopausal women, 6.1% (24/392) in postmenopausal women, and 5.3% (11/206) in women receiving hormone replacement therapy. The weight gain in premenopausal women was equal to that in postmenopausal women. Metabolic syndrome and weight gain were independent risk factors for NAFLD in pre-and postmenopausal women, but age was an independent risk factor in premenopausal women only. CONCLUSION: Aging is a risk factor for NAFLD in premenopausal women, independent of weight gain or influence of metabolic syndrome. | Masahide Hamaguchi Takao Kojima Akihiro Ohbora Noriyuki Takeda Michiaki Fukui Takahiro Kato | 2012 | World Journal of Gastroenterology2012，18，3： | 19 |
| 5 | 中国新疆马鹿亚种头骨形态的地理变化(英文)显示文摘新疆马鹿(Cervus elaphus)有3个亚种(塔里木亚种C. e . yarkandensis、天山亚种C. e . songaricus和阿勒泰亚种C. e . sibiricus)。本文报道新疆马鹿3个亚种头骨形态学特征描述和14项形态学指标测定。被测定的指标主要有颅全长(GLC)、颜面长(FL)、鼻骨全长(GLN)、前头长( MFL)、眼窝长(OFW)、基底全长(CBL)、口盖最大幅(GPB)、前臼齿间距离(Pm-P)、眼间最小幅(ZB)、筋突起高(CH)、关筋突起高(LH)、牙齿间隙裂高(DH)、前下颚骨高(HMP2)、后下颚骨高(HMM3) ,采用主成分分析并在这3个亚种之间进行了比较。结果表明: 1)阿勒泰亚种的头骨长度和高度值比塔里木亚种大,宽度值比塔里木亚种小; 2)天山亚种的头骨大小一般处在塔里木亚种和阿勒泰亚种的中间,但三者之间没有显著性差异; 3)阿勒泰亚种和天山亚种的头骨形态测量数据比较接近,塔里木亚种的头骨形态比较特殊(塔里木亚种的头骨短而宽,明显区别于其他两亚种的特征)。在新疆导致马鹿3个亚种头骨形态差异的主要因素有栖息地环境和气候因素的差异。阿勒泰亚种和天山亚种栖息在大陆性气候寒冷区的针叶林中,冬天气候比较寒冷;塔里木亚种栖息在大陆性气候温热区的塔里木河流域胡杨林中,气候干旱炎热。因此,阿勒泰和天山亚种在适应寒冷的气候并适应生软食物的食性过程中头骨变成长细,而塔里木亚种长期适应干旱炎热并适应生硬食物的食性使头骨变的短而宽。 | 马合木提.哈力克 艾尼瓦尔.吐米尔 吾玛尔.阿不力孜 Noriyuki Ohtaishi | 2005 | 兽类学报2005，25，4： | 14 |
| 6 | Identification of individuals with non-alcoholic fatty liver disease by the diagnostic criteria for the metabolic syndrome显示文摘AIM:To clarify the efficiency of the criterion of metabolic syndrome to detecting non-alcoholic fatty liver disease(NAFLD).METHODS:Authors performed a cross-sectional study involving participants of a medical health checkup program including abdominal ultrasonography.This study involved 11 714 apparently healthy Japanese men and women,18 to 83 years of age.NAFLD was defined by abdominal ultrasonography without an alcohol intake of more than 20 g/d,known liver disease,or current use of medication.The revised criteria of the National Cholesterol Education Program Adult Treatment PanelⅢ were used to characterize the metabolic syndrome.RESULTS:NAFLD was detected in 32.2%(95%CI:31.0%-33.5%)of men(n=1874 of 5811)and in 8.7%(95%CI:8.0%-9.5%)of women(n=514 of 5903).Among obese people,the prevalence of NAFLD was as high as 67.3%(95%CI:64.8%-69.7%)in men and 45.8%(95%CI:41.7%-50.0%)in women.Although NAFLD was thought of as being the liver phenotype of metabolic syndrome,the prevalence of the metabolic syndrome among subjects with NAFLD was low both in men and women.66.8%of men and 70.4%of women with NAFLD were not diagnosed with the metabolic syndrome.48.2%of men with NAFLD and 49.8%of women with NAFLD weren't overweight[body mass index(BMI)≥25 kg/m2].In the same way,68.6%of men with NAFLD and 37.9%of women with NAFLD weren't satisfied with abdominal classification(≥90 cm for men and≥80 cm for women).Next,authors defined it as positive at screening for NAFLD when participants satisfied at least one criterion of metabolic syndrome.The sensitivity of the definition'at least 1 criterion'was as good as 84.8%in men and 86.6%in women.Separating subjects by BMI,the sensitivity was higher in obese men and women than in non-obese men and women(92.3%vs 76.8%in men,96.1%vs 77.0%in women,respectively).CONCLUSION:Authors could determine NAFLD effectively in epidemiological study by modifying the usage of the criteria for metabolic syndrome. | Masahide Hamaguchi Noriyuki Takeda Takao Kojima Akihiro Ohbora Takahiro Kato Hiroshi Sarui Michiaki Fukui Chisato Nagata Jun Takeda | 2012 | World Journal of Gastroenterology2012，18，13： | 13 |
| 7 | Protective effect of alcohol consumption for fatty liver but not metabolic syndrome显示文摘AIM:To investigate the effect of alcohol on the metabolic syndrome (MS) and fatty liver in Japanese men and women.METHODS:A cross-sectional study was conducted in a medical health checkup program at a general hospital.This study involved 18 571 Japanese men and women,18-88 years of age,with a mean body mass index of 22.6 kg/m 2.A standardized questionnaire was administered.The total amount of alcohol consumed per week was calculated,and categorized into four grades.Fatty liver was examined by ultrasound modified criteria of the revised National Cholesterol Educa-tion Program Adult Treatment Panel Ⅲ and the new International Diabetes Federation.RESULTS:The prevalence of fatty liver decreased in men and women with light to moderate alcohol consumption,whereas the prevalence of MS was not so changed.The prevalence of fatty liver of any grade in men was lower than that in those with no or minimal alcohol consumption.In women with light to moderate alcohol consumption,prevalence of fatty liver was lower than that in women with no or minimal alcohol consumption.By logistic regression analysis,the odds ratio (OR) for MS in women with light alcohol consumption was decreased to < 1.0,but this change was not clear in men.The OR for fatty liver was clearly < 1.0 in men with any level of alcohol consumption and in women with light to moderate consumption.CONCLUSION:Light to moderate alcohol consumption has a favorable effect for fatty liver,but not for MS in Japanese men and women. | Masahide Hamaguchi Takao Kojima Akihiro Ohbora Noriyuki Takeda Michiaki Fukui Takahiro Kato | 2012 | World Journal of Gastroenterology2012，18，2： | 12 |
| 8 | Hepatic clearance measured with ^(99m)Tc-GSA single-photon emission computed tomography to estimate liver fibrosis显示文摘AIM: To evaluate the clinical utility of hepatic clearance(HC) measured with technetium-99m-diethylenetriaminepenta-acetic acid-galactosyl human serum albumin(99mTc-GSA) single-photon emission computed tomography(SPECT) to estimate the degree of liver fibrosis.METHODS:Seventy-eight consecutive patients who underwent initial hepatectomy due to hepatocellular carcinoma were enrolled in this study.Indocyanine green clearance(ICG R15),quantitative indices estimated by 99mTc-GSA[the receptor index(LHL15 and HH15)and HC via SPECT analysis],and conventional liver function tests were performed before hepatectomy.Correlations among the quantitative indices for liver functional reserve,conventional liver function tests,andthe degree of liver fibrosis were evaluated.RESULTS:The degree of liver fibrosis was correlated with ICG R15,HH15,LHL15,and HC.HC showed the best correlation with conventional liver function tests.According to multivariate analysis,HC and LHL15 were significant independent predictors of severe fibrosis.HC was the most valuable index for predicting severe fibrosis.CONCLUSION:HC measured with 99mTc-GSA SPECT is a reliable index for assessing liver fibrosis before hepatectomy. | Masahiko Taniguchi Atsutaka Okizaki Kenji Watanabe Koji Imai Koichiro Uchida Takahiro Einama Noriyuki Shuke Naoyuki Miyokawa Hiroyuki Furukawa | 2014 | World Journal of Gastroenterology2014，20，44： | 11 |
| 9 | Long-term outcomes and prognostic factors of patients with obstructive colorectal cancer: A multicenter retrospective cohort study显示文摘AIM: To investigate the long-term oncologic outcomes and prognostic factors in patients with obstructive colorectal cancer(CRC) at multiple Japanese institutions.METHODS: We identified 362 patients diagnosed with obstructive colorectal cancer from January 1, 2002 to December 31, 2012 in Yokohama Clinical Oncology Group's department of gastroenterological surgery. Among them, 234 patients with stage Ⅱ/Ⅲ disease who had undergone surgical resection of their primary lesions were analyzed, retrospectively. We report the long-term outcomes, the risk factors for recurrence, and the prognostic factors.RESULTS: The five-year disease free survival and cancer-specific survival were 50.6% and 80.3%, respectively. A multivariate analysis showed the ASAPS(HR = 2.23, P = 0.026), serum Albumin ≤ 4.0 g/d L(HR = 2.96, P = 0.007), T4 tumor(HR = 2.73, P = 0.002) and R1 resection(HR = 6.56, P = 0.02) to be independent risk factors for recurrence. Furthermore, poorly differentiated cancers(HR = 6.28, P = 0.009), a T4 tumor(HR = 3.46, P = 0.011) and R1 resection(HR = 6.16, P = 0.006) were independent prognostic factors in patients with obstructive CRC.CONCLUSION: The outcomes of patients with obstructive CRC was poor. T4 tumor and R1 resection were found to be independent prognostic factors for both recurrence and survival in patients with obstructive CRC. | Ishibe Atsushi Ota Mitsuyoshi Yamaguchi Kazuya Kaida Syuhei Kamiya Noriyuki Momiyama Masashi Watanabe Akira Sekizawa Kentaro Kamimukai Nobuyuki Sugimasa Natsuko Watanabe Jun Ichikawa Yasushi Kunisaki Chikara Endo Itaru | 2016 | World Journal of Gastroenterology2016，22，22： | 9 |
| 10 | Hybrid Rubisco with Complete Replacement of Rice Rubisco Small Subunits by Sorghum Counterparts Confers C4 Plant-like High Catalytic Activity显示文摘Photosynthetic rate at the present atmospheric condition is limited by the CO2-fixing enzyme ribulose-1,5-bisphosphate carboxylase/oxygenase(Rubisco)because of its extremely low catalytic rate(kcat)and poor affinity for C02(Kc)and specificity for CO2(Sc/O).Rubisco in C4 plants generally shows higher k cat than that in C3 plants.Rubisco consists of eight large subunits and eight small subunits(RbcS).Previously,the chimeric incorporation of sorghum C4-type RbcS significantly increased the k cat of Rubisco in a C3 plant,rice.In this study,we knocked out rice RbcS multigene family using the CRISPR-Cas9 technology and completely replaced rice RbcS with sorghum RbcS in rice Rubisco.Obtained hybrid Rubisco showed almost C4 plant-like catalytic properties,i.e.,higher kcai,higher Kc,and lower Sc/O.Transgenic lines expressing the hybrid Rubisco accumulated reduced levels of Rubisco,whereas they showed slightly but significantly higher photosynthetic capacity and similar biomass production under high C 02 condition compared with wild-type rice.High-resolution crystal structural analysis of the wild-type Rubisco and hybrid Rubisco revealed the structural differences around the central pore of Rubisco and the pC-pD hairpin in RbcS.We propose that such differences,particularly in the pC-pD hairpin,may impact the flexibility of Rubisco catalytic site and change its catalytic properties. | Hiroyoshi Matsumura Keita Shiomi Akito Yamamoto Yuri Taketani Noriyuki Kobayashi Takuya Yoshizawa Shun-ichi Tanaka Hiroki Yoshikawa Masaki Endo Hiroshi Fukayama | 2020 | Molecular Plant2020，13，11： | 8 |

| 12 | 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 |

| 14 | Life prognosis of sentinel node navigation surgery for early-stage gastric cancer:Outcome of lymphatic basin dissection显示文摘BACKGROUND Lymphatic basin dissection is a sentinel node biopsy method that is specific for gastric cancer.In this method,the dyed lymphatic system is dissected en bloc,and sentinel nodes are identified at the back table(ex vivo).Even with lymphatic basin dissection,blood flow to the residual stomach can be preserved,and functionpreserving curative gastrectomy can be performed.The oncological safety of function-preserving curative gastrectomy combined with lymphatic basin dissection has not yet been fully investigated.We hypothesized that the oncological safety of sentinel node navigation surgery(SNNS)is not inferior to that of the guidelines.AIM To investigate the life prognosis of SNNS for gastric cancer in comparison with guidelines surgery.METHODS This was a retrospective cohort study.Patients were selected from gastric cancer patients who underwent sentinel node biopsy from April 1999 to March 2016.Patients from April 1999 to August 2008 were from the Department of Surgery II,Kanazawa University Hospital,and patients from August 2009 to March 2016 were from the Department of Surgical Oncology,Kanazawa Medical University Hospital.Patients who were diagnosed with gastric cancer,which was preoperatively diagnosed as superficial type(type 0),5 cm or less in length,clinical T1-2 and node negative,and underwent various gastrectomies guided by sentinel node navigation were retrospectively collected.The overall survival(OS)and relapsefree survival(RFS)of these patients(SNNS group)were investigated.Patients with gastric cancer of the same stage and who underwent guidelines gastrectomy with standard nodal dissection were also selected as the control group.RESULTS A total of 239 patients in the SNNS group and 423 patients in the control group were included.Pathological nodal metastasis was observed in 10.5%and 10.4%of the SNNS and control groups,respectively.The diagnostic abilities of sentinel node biopsy were 84%and 98.6%for sensitivity and accuracy,respectively.In the SNNS group,81.6%of patients underwent modified gastrectomy or functionpreserving curative gastrectomy with lymphatic basin dissection,in which the extent of nodal dissection was further reduced compared to the guidelines.The OS rate in the SNNS group was 96.8%at 5 years and was significantly better than 91.3%in the control group(P=0.0014).The RFS rates were equal in both groups.After propensity score matching,there were 231 patients in both groups,and the cumulative recurrence rate was 0.43%at 5 years in the SNNS group and 1.30%in the control group,which was not statistically different.CONCLUSION The oncological safety of patients who undergo gastrectomy guided by sentinel node navigation is not inferior to that of the guidelines surgery. | Shinichi Kinami Naohiko Nakamura Tomoharu Miyashita Hidekazu Kitakata Sachio Fushida Takashi Fujimura Yasuo Iida Noriyuki Inaki Toru Ito Hiroyuki Takamura | 2021 | World Journal of Gastroenterology2021，27，46： | 5 |
| 15 | Endocytoscopic narrow-band imaging efficiency for evaluation of inflammatory activity in ulcerative colitis显示文摘AIM:To assess the efficacy of endocytoscopic narrowband imaging(EC-NBI)for evaluating the severity of inflammation in ulcerative colitis(UC).METHODS:This retrospective study was conducted at a single tertiary care referral center.We included UC patients who underwent colonoscopy with endocytoscopy from July 2010 to December 2013.ECNBI was performed,and the images were evaluated by assessing visibility,increased vascularization,and the increased calibers of capillaries and were classified as Obscure,Visible or Dilated.Obscure was indicative of inactive disease,while Visible and Dilated were indicative of acute inflammation.This study received Institutional Review Board approval.The primary outcome measures included the diagnostic ability of EC-NBI to distinguish between active and inactive UC on the basis of histological activity.The conventional endoscopic images were classified according to the Mayo endoscopic score.A score of 0 or 1 indicated inactive disease,whereas a score of 2 indicated active disease.RESULTS:Fifty-two patients were enrolled.There was a strong correlation between the EC-NBI findings and the histological assessment(r=0.871,P<0.01).The sensitivity,specificity,positive predictive value,negative predictive value,and accuracy of EC-NBI for diagnosing acute inflammation were 84.0%,100%,87.1%,100%,and 92.3%,respectively,while those for the Mayo endoscopic score were 100%,40.7%,100%,61.0%,and 69.2%,respectively.Compared with conventional endoscopy,EC-NBI was superior in diagnostic specificity,negative predictive value,and accuracy(P<0.001,P=0.001 and P=0.047,respectively).CONCLUSION:The EC-NBI finding of capillaries in the rectal mucosa was strongly correlated with histological inflammation and aided in the differential diagnosis between active and inactive UC. | Yasuharu Maeda Kazuo Ohtsuka Shin-ei Kudo Kunihiko Wakamura Yuichi Mori Noriyuki Ogata Yoshiki Wada Masashi Misawa Akihiro Yamauchi Seiko Hayashi Toyoki Kudo Takemasa Hayashi Hideyuki Miyachi Fuyuhiko Yamamura Fumio Ishida Haruhiro Inoue Shigeharu Hamatani | 2015 | World Journal of Gastroenterology2015，21，7： | 4 |
| 16 | 均匀充量柴油燃烧的优化控制方法的研究显示文摘作为降低柴油机废气排放的一种方法,对均匀充量柴油燃烧技术(HCDC)进行了试验,将一部分燃油喷入进气道以形成均匀预混合气,这样,在直接喷入气缸的柴油着火之前,这种均匀预混合气从进气道进入气缸。试验结果显示,能显著降低NO_x和排烟。如果柴油预先与空气混合,预混合气会过早地自燃,从而难以保持在上止点附近着火定时,从而限制了柴油机的运行工况。虽然,降低排放的主要目标是实现高负荷工况下的稳定低排放燃烧,但是柴油机实际运行大多包括部分负荷工况。因此,即使在部分负荷运行范围内,如果HCDC能够实现低排放燃烧,则能够大大降低柴油机废气排放。因此在本研究中,在低负荷和中等负荷运行范围内,试图通过直喷燃油喷油定时的控制和EGR来改善燃烧和降低排放。对于全负荷工况,力求通过燃用高抗爆震性能的含氧化合物的柴油来优化HCDC。试验结果表明,在油门半开和低预混合燃油比的条件下,通过延迟(优化)直喷燃油喷油定时,能大大降低NO_x,而不增加排烟。这与在高预混合燃油比条件下所获得的效果是相同的。还发现通过优化预混合燃油比和EGR率,能降低NO_x排放,而不增加排烟。此外,能够确认,经在柴油中混入MTBE(甲基特丁基醚),当HCDC在柴油机整个运行范围起作用时,NO_x和排烟都能得到降低。通过延迟直喷燃油喷油定时,NO_x和排烟还能得到进一步降低。 | Matsuo Odaka Hisakazu Suzuki Noriyuki Koike 马玲 | 2001 | 国外内燃机2001，33，5： | 4 |

| 18 | Efficacy of long-term rifaximin treatment for hepatic encephalopathy in the Japanese显示文摘BACKGROUND Hepatic encephalopathy(HE)is a complication of liver cirrhosis and can result in neuropsychological and neuromuscular dysfunctions in patients.Rifaximin,an antibiotic,has been reported to decrease the occurrence of overt HE and also improve cognitive function in studies from Europe and the United States of America.There is not enough evidence of the relationship between the long-term use of rifaximin and its clinical effects in the Japanese.AIM To determine the clinical effects of long-term rifaximin therapy in decompensated liver cirrhosis patients,with overt HE or hyperammonemia.METHODS In this single-center retrospective observational cohort study,we reviewed the data of 38 patients who had taken rifaximin at the dose of 1200 mg/d for more than 24 wk.The primary outcome measured was the efficacy of long-term rifaximin use,and secondary outcome measured was the safety of its long-term use as determined by its influence on portosystemic shunts as well as Escherichia coli-related infections.Moreover,we compared the prognosis between the rifaximin group and control cases,matched for hepatic elasticity assessed by magnetic resonance ela-stography,age,and Child-Pugh classification.RESULTS Of the 38 patients included in the study,12(31.6%)had overt HE,27(71.1%)had complications of esophageal varices,and 9(23.7%)had hepatocellular carcinoma(HCC).The control group was matched for age,Child-Pugh classification,liver stiffness,and presence of HCC.The median of serum ammonia level before treatment was 104μg/dL(59-297),and 2 wk after treatment,it significantly decreased to 85μg/dL(34-153)(P=0.002).A significantly low value of 80.5μg/dL(44-150)was maintained 24 wk after treatment.The long-term use of rifaximin did not cause a decline in liver function.Diarrhea occurred in 2 patients,who improved with the administration of probiotics,and there were no cases of aborted rifaximin therapy owing to adverse events.In patients with Child C,the survival was short,but there was no significant difference compared with that of the control group.CONCLUSION Rifaximin therapy improves overt HE.The long-term use of rifaximin in the Japanese is effective and safe. | Shinya Nishida Koichi Hamada Noriyuki Nishino Daizo Fukushima Ryota Koyanagi Yoshinori Horikawa Yoshiki Shiwa Satoshi Saitoh | 2019 | World Journal of Hepatology2019，11，6： | 3 |
