1烧结工艺使用气体燃料喷入技术减少CO_2排放显示文摘JFE钢铁公司开发了在烧结矿表面喷入含氢的气体燃料技术,可不增加焦粉配比,提高烧结矿质量。使用该技术,含氢气体可部分替代焦粉,使1200~1400℃的燃烧层变宽成为可能。通过X射线对多孔状的烧结饼进行CT检查与烧结锅试验,从理论到实践都证明了喷入燃料气体技术的使用效果。保持1200~1400℃的温度带,为生产高强度、高还原性的烧结矿至关重要,它能使合适的温度带变宽、液相率增加、提高1~5mm孔隙间的熔合并提升烧结矿强度。大于5mm的孔隙的烧结矿数量增多提高了料层的透气性,低温烧结工艺也抑制了铁矿石的自身熔化。而在未熔化的铁矿石中,小于1μm的微孔隙的存在也使烧结矿的还原性提高,从而改善烧结饼的孔隙结构,提高烧结矿质量。2009年1月,京浜1号烧结机应用了该技术,到目前为止工况稳定。结果,烧结工序的能源利用率大幅提升,减排CO2约6万t/a。Nobuyuki Oyama Yuji Iwami Satoshi Machida Takahide Higuchi Tetsuya Yamamoto Yushinori Watanabe Michitaka Sato Kanji Takeda Masakata Shimizu Koki Nishioka 何海良 2013世界钢铁2013,,1:11

3Comparison of PPIs and H_2-receptor antagonists plus prokinetics for dysmotility-like dyspepsia显示文摘AIM:To compare efficacy of proton pump inhibitors(PPIs)with H2-receptor antagonists(H2RAs)plus prokinetics(Proks)for dysmotility-like symptoms in functional dyspepsia(FD).METHODS:Subjects were randomized to receive openlabel treatment with either rabeprazole 10 mg od(n= 57)or famotidine 10 mg bid plus mosapride 5 mg tid(n=57)for 4 wk.The primary efficacy endpoint was change(%)from baseline in total dysmotility-like dyspepsia symptom score.The secondary efficacy endpoint was patient satisfaction with treatment.RESULTS:The improvement in dysmotility-like dyspep-sia symptom score on day 28 was significantly greater in the rabeprazole group(22.5%±29.2%of baseline) than the famotidine+mosapride group(53.2%± 58.6%of baseline,P<0.0001).The superior benefit of rabeprazole treatment after 28 d was consistent regardless of Helicobacter pylori status.Significantly more subjects in the rabeprazole group were satisfied or very satisfied with treatment on day 28 than in the famotidine+mosapride group(87.7%vs 59.6%,P= 0.0012).Rabeprazole therapy was the only significant predictor of treatment response(P<0.0001),defined as a total symptom score improvement≥50%.CONCLUSION:PPI monotherapy improves dysmotility-like symptoms significantly better than H2RAs plus Proks,and should be the treatment of first choice for Japanese FD.Masahiro Sakaguchi Miyuki Takao Yasuo Ohyama Hiroshi Oka Hiroshi Yamashita Takumi Fukuchi Kiyoshi Ashida Masahiro Murotani Masuyo Murotani Kazuo Majima Hiroshi Morikawa Takashi Hashimoto Keisuke Kiyota Hirohiko Esaki Kanji Amemoto Gouhei Isowa Fumiyuki Takao 2012World Journal of Gastroenterology2012,18,13:8
4Genetic polymorphisms in glutathione S-transferase T1 affect the surgical outcome of varicocelectomies in infertile patients显示文摘谷胱甘肽 S-transferases (GST ) , superoxide dismutase 2 (SOD2 ) 并且 NAD (P) H:quinone oxidoreductase (NQO1 ) 1 是抗氧化剂酶基因。GST, SOD2 和 NQO1 的多型性被报导了影响单个危险性到各种各样的疾病。在更早的研究,我们获得了有精索静脉曲张的谷胱甘肽 S-transferase T1 (GSTT1 )-wt 病人的一个子集可以展出的初步的调查结果对 varicocelectomy 的好反应。在这研究,我们扩大了更早的学习在不肥沃的人口决定每基因的遗传型的分发并且评估这些基因的多型性是否影响精索静脉曲张的外科的治疗的结果。我们分析了 72 个不肥沃的精索静脉曲张病人,没有精索静脉曲张的 202 个不肥沃的病人和 101 男控制。GST 的遗传型被聚合酶链反应(PCR ) 决定。SOD2 和 NQO1 的 Genotyping 用 PCR 限制碎片长度多型性(PCR-RFLP ) 被执行方法。对 varicocelectomy 的显著地更好的回答分别地与 GSTT1 空的遗传型(35.3%) 或 NQO1-Pro/Ser 遗传型(45.2%) 比在那些与 GSTT1-wt 遗传型(63.2%) 和 NQO1-Ser/Ser 遗传型(80.0%) 在病人被发现。谷胱甘肽 S-transferase M1/T1, SOD2 和 NQO1 遗传型的频率没在精索静脉曲张病人,自发的不肥沃的病人和男控制之中显著地不同。GSTT1 遗传型在 varicocelectomy 以后与精液参数的改进被联系。因为有 NQO1-Ser/Ser 遗传型的病人的数字不是足够的得出明确的结论,有 varicocelectomy 的 NQO1 遗传型的协会要求进一步的调查。Kentaro Ichioka Kanji Nagahama Kazutoshi Okubo Takeshi Soda Osamu Ogawa Hiroyuki Nishiyama 2009Asian Journal of Andrology2009,11,3:7
5Anterolateral rotatory instability in vivo correlates tunnel position after anterior cruciate ligament reconstruction using bone-patellar tendon-bone graft显示文摘AIM To quantitatively assess rotatory and anterior-posterior instability in vivo after anterior cruciate ligament(ACL) reconstruction using bone-patellar tendon-bone(BTB) autografts, and to clarify the influence of tunnel positions on the knee stability.METHODS Single-bundle ACL reconstruction with BTB autograft was performed on 50 patients with a mean age of 28 years using the trans-tibial(TT)(n = 20) and trans-portal(TP)(n = 30) techniques. Femoral and tibial tunnel positions were identified from the high-resolution 3 D-CT bone models two weeks after surgery. Anterolateral rotatory translation was examined using a Slocum anterolateral rotatory instability test in open magnetic resonance imaging(MRI) 1.0-1.5 years after surgery, by measuring anterior tibial translation at the medial and lateral compartments on its sagittal images. Anterior-posterior stability was evaluated with a Kneelax3 arthrometer.RESULTS A total of 40 patients(80%) were finally followed up. Femoral tunnel positions were shallower(P < 0.01) and higher(P < 0.001), and tibial tunnel positions were more posterior(P < 0.05) in the TT group compared with the TP group. Anterolateral rotatory translations in reconstructed knees were significantly correlated with the shallow femoral tunnel positions(R = 0.42, P < 0.01), and the rotatory translations were greater in the TT group(3.2 ± 1.6 mm) than in the TP group(2.0 ± 1.8 mm)(P < 0.05). Side-to-side differences of Kneelax3 arthrometer were 1.5 ± 1.3 mm in the TT, and 1.7 ± 1.6 mm in the TP group(N.S.). Lysholm scores, KOOS subscales and reinjury rate showed no difference between the two groups.CONCLUSION Anterolateral rotatory instability significantly correlated shallow femoral tunnel positions after ACL reconstruction using BTB autografts. Clinical outcomes, rotatory and anterior-posterior stability were overall satisfactory in both techniques, but the TT technique located femoral tunnels in shallower and higher positions, and tibial tunnels in more posterior positions than the TP technique, thus increased the anterolateral rotation. Anatomic ACL reconstruction with BTB autografts may restore knee function and stability.Yasutaka Tashiro Ken Okazaki Koji Murakami Hirokazu Matsubara Kanji Osaki Yukihide Iwamoto Yasuharu Nakashima 2017World Journal of Orthopedics2017,8,12:5
6Factors associated with the overall survival of elderly patients with hepatocellular carcinoma显示文摘AIM:To identify the factors associated with overall survival of elderly patients with hepatocellular carcinoma(HCC).METHODS:A total of 286 patients with HCC(male/female:178/108,age:46-100 years),who were diagnosed and treated by appropriate therapeutic procedures between January 2000 and December 2010,were enrolled in this study.Patients were stratified into two groups on the basis of age:Elderly(≥ 75 years old) and non-elderly(< 75 years old).Baseline clinical characteristics as well as cumulative survival rates were then compared between the two groups.Univariate and multivariate analyses were used to identify the factors associated with prolonged overall survival of patients in each group.Cumulative survival rates in the two groups were calculated separately for each modified Japan Integrated Stage score(mJIS score) category by the Kaplan-Meier method.In addition,we compared the cumulative survival rates of elderly and non-elderly patients with good hepatic reserve capacity(≤ 2 points as per mJIS).RESULTS:In the elderly group,the proportion of female patients,patients with absence of hepatitis B or hepatitis C viral infection,and patients with coexisting extrahepatic comorbid illness was higher(56.8% vs 31.1%,P < 0.001;27.0% vs 16.0%,P = 0.038;33.8% vs 22.2%,P = 0.047;respectively) than that in the nonelderly group.In the non-elderly group,the proportion of hepatitis B virus(HBV)-infected patients was higher than that in the elderly group(9.4% vs 0%,P = 0.006).The cumulative survival rates in the elderly group were 53.7% at 3 years and 32.9% at 5 years,which were equivalent to those in the non-elderly group(55.9% and 39.4%,respectively),as shown by a log-rank test(P = 0.601).In multivariate analysis,prolonged survival was significantly associated with the extent of liver damage and stage(P < 0.001 and P < 0.001,respectively),but was not associated with patient age.However,on individual evaluation of factors in both groups,stage was significantly(P < 0.001) associated with prolonged survival.Regarding mJIS scores of ≤ 2,the rate of female patients with this score was higher in the elderly group when compared to that in the non-elderly group(P = 0.012) and patients ≥ 80 years of age tended to demonstrate shortened survival.CONCLUSION:Survival of elderly HCC patients was associated with liver damage and stage,but not age,except for patients ≥ 80 years with mJIS score ≤ 2.Hideki Fujii Yoshito Itoh Naoki Ohnishi Masafumi Sakamoto Tohru Ohkawara Yoshihiko Sawa Koichi Nishida Yasuo Ohkawara Kanji Yamaguchi Masahito Minami Takeshi Okanoue 2012World Journal of Gastroenterology2012,18,16:4

9Triple pelvic osteotomy: Report of our mid-term results and review of literature显示文摘A wide variety of pelvic osteotomies have been developed for the treatment of developmental dysplasia of the hip(DDH). In the present paper, we present a detailed review of previous studies of triple osteotomy as an alternative treatment for DDH. We also report our experience treating 6 adult cases of DDH by triple osteotomy in order to highlight the various aspects of this procedure.The mean age of our patients was 31.2 years with a mean follow-up period of 6 years. We assessed range of motion, center-edge angle, acetabular index angle, Sharp angle, acetabulum head index, head lateralization index, Japanese Orthopedic Association score, Harris hip score, patient satisfaction, and the difference between lower limb lengths before and after the procedure. At final follow-up, clinical scores were significantly improved and radiographic parameters also showed good correction of acetabulum.Tomohiro Mimura Kanji Mori Taku Kawasaki Shinji Imai Yoshitaka Matsusue 2014World Journal of Orthopedics2014,5,1:4
10Evaluation of prognostic factors and scoring system in colonic perforation显示文摘AIM: To study the significance of scoring systems assessing severity and prognostic factors in patients with colonic perforation. METHODS: A total of 26 patients (9 men, 17 women; mean age 72.7 ± 11.6 years) underwent emergency operation for colorectal perforation in our institution between 1993 and 2005. Several clinical factors were measured preoperatively and 24 h postoperatively. Acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ), Mannheim peritonitis index (MPI) and peritonitis index of Altona (PIA Ⅱ) scores were calculated preoperatively. RESULTS: Overall postoperative mortality rate was 23.1% (6 patients). Compared with survivors, non- survivors displayed low blood pressure, low serum protein and high serum creatinine preoperatively, and low blood pressure, low white blood cell count, low pH, low PaO2/FiO2, and high serum creatinine postoperatively. APACHE Ⅱ score was significantly lower in survivors than in non-survivors (10.4 ± 3.84 vs 19.3 ± 2.87, P = 0.00003). Non-survivors tended to display high MPI score and low PIA Ⅱ score, but no signif icant difference was identif ied. CONCLUSION: Pre- and postoperative blood pressure and serum creatinine level appear related to prognosis of colonic perforation. APACHE Ⅱ score is most associated with prognosis and scores ≥ 20 are associated with signif icantly increased mortality rate.Atsushi Horiuchi Yuji Watanabe Takashi Doi Kouichi Sato Syungo Yukumi Motohira Yoshida Yuji Yamamoto Hiroki Sugishita Kanji Kawachi 2007World Journal of Gastroenterology2007,13,23:4
11Neutrophil-mediated liver injury during hepatic ischemia-reperfusion in rats显示文摘BACKGROUND: Neutrophil plays an important role in hepatic ischemia-reperfusion injury. We investigated neutrophil infiltration in liver tissue, Kupffer cells’ role in neutrophil accumulation, and apoptosis and regeneration of hepatocytes in liver ischemia-reperfusion injury. METHODS: Vascular microclamps were placed across the pedicles of the median and left lateral lobes for 90 minutes after 30% hepatectomy with the resection of caudate, right lateral and quadrate lobes and papillary process. Gadolinium chloride (GdCl3) was used to destroy Kupffer cells. Neutrophil activity was inhibited with Urge-8, a monoclonal antibody against neutrophil produced in our laboratory. GdCl3 (10 mg/kg) and Urge-8 (50 mg/kg) were given intravenously in respective groups. Ischemia control, GdCl3 and Urge-8 groups were compared. RESULTS: Following hepatic reperfusion, serum interleukin-8 (IL-8) levels and hepatic neutrophil counts peaked at 3 hours, and peak concentrations of alanine aminotransferase (ALT) occurred at 6 hours. Animals of the control group showed increases in neutrophil infiltration in liver tissue, liver enzyme levels, and apoptosis index of hepatocytes and decreases in overall survival rate and proliferating cell nuclear antigen (PCNA) expression of hepatocytes. The survival rates and PCNA proportion of hepatocytes were higher and the levels of hepatic neutrophil infiltration, liver enzymes, and hepatocyte apoptosis after reperfusion were lower in the GdCl3 and Urge-8 groups than those in the ischemia control group. CONCLUSIONS: Blockades of Kupffer cells’ activity and neutrophil infiltration by GdCl3 and Urge-8 eliminate neutrophil-mediated hepatic injury and enhance subsequent hepatic regeneration during liver ischemiareperfusion.Motomichi Sato Kanji Kawachi Yuji Abe 2006Hepatobiliary & Pancreatic Diseases International2006,5,3:4
12Real-world efficacy of daclatasvir and asunaprevir with respect to resistance-associated substitutions显示文摘AIM To investigate daclatasvir(DCV) and asunaprevir(ASV) efficacy in hepatitis C(HCV) patients, with respect to resistance-associated substitutions(RASs).METHODS A total of 392 HCV-infected patients from multiple centers were included in this study. We evaluated their clinical courses and sustained virologic responses(SVR) according to pretreatment factors(gender, age, history of interferon-based regimens, platelet counts, level of viremia, pretreatment NA5A:L31, and Y93 substitutions). We also analyzed the pretreatment and post-treatment major RASs of NS3:D168, NS5A:L31 and Y93 substitutions using a direct-sequencing method in 17 patients who were unable to achieve SVR at 12 wk after treatment completion(SVR12).RESULTS The overall SVR12 rate was 88.3%. Thirty-one patients discontinued treatment before 24 wk because of adverse events, 23 of whom achieved SVR12. There were no significant differences in SVR12 rates with respect to gender, age, history of interferon-based regimens, and platelet counts. The SVR12 rate in patients with viral loads of ≥ 6.0 log IU/m L was significantly lower than those with viral loads of < 6.0 log IU/m L(P < 0.001). The SVR12 rate in patients with Y93 substitution-positive was significantly lower than those with Y93 substitution-negative(P < 0.001). The L31 substitution-positive group showed a lower SVR12 rate than the L31 substitution-negative group, but the difference was not statistically significant. Seventeen patients who did not achieve SVR12 and had available pretreatment and post-treatment sera had additional RASs in NS3:D168, NS5:L31, and Y93 substitution at treatment failure.CONCLUSION Combination of DCV and ASV is associated with a high SVR rate. Baseline RASs should be thoroughly assessed to avoid additional RASs after treatment failure.Hideki Fujii Atsushi Umemura Taichiro Nishikawa Kanji Yamaguchi Michihisa Moriguchi Hideki Nakamura Kohichiroh Yasui Masahito Minami Saiyu Tanaka Hiroki Ishikawa Hiroyuki Kimura Shiro Takami Yasuyuki Nagao Toshihide Shima Yoshito Itoh 2017World Journal of Hepatology2017,9,25:3
13Distribution of HBV genotypes among HBV carriers in Benin:phylogenetic analysis and virological characteristics of HBV genotype E显示文摘AIM: To determine the distribution of Hepatitis B virus (HBV) genotypes in Benin, and to clarify the virological characteristics of the dominant genotype.METHODS: Among 500 blood donors in Benin, 21 HBsAg-positive donors were enrolled in the study. HBV genotypes were determined by enzyme immunoassay and restriction fragment length polymorphism. Complete genome sequences were determined by PCR and direct sequencing.RESULTS: HBV genotype E (HBV/E) was detected in 20/21 (95.2%), and HBV/A in 1/21 (4.8%). From the age-specific prevalence of HBeAg to anti-HBe seroconversion (SC) in 19 HBV/E subjects, SC was estimated to occur frequently in late teens in HBV/E.The comparison of four complete HBV/E genomes from HBeAg-positive subjects in this study and five HBV/E sequences recruited from the database revealed that HBV/E was distributed throughout West Africa with very low genetic divers ity (nucleotide homology 96.7-99.2%).Based on the sequences in the basic core promoter (BCP)to precore region of the nine HBV/E isolates compared to those of the other genotypes, a nucleotide substitution in the BCP, G1757A, was observed in HBV/E.CONCLUSION: HBV/E is predominant in the Republic of Benin, and SC is estimated to occur in late teens in HBV/E. The specific nucleotide substitution G1757A in BCP, which might influence the virological characteristics,is observed in HBV/E.Kei Fujiwara Yasuhito Tanaka Etsuro Orito Tomoyoshi Ohno Takanobu Kato Kanji Sugihara Izumi Hasegawa Mayumi Sakurai Kiyoaki Ito Atsushi Ozasa Yuko Sakamoto Isao Arita Ahmed El-Gohary Agossou Benoit Sophie I Ogoundele-Akplogan Namiko Yoshihara Ryuzo Ueda Masashi Mizokami 2005World Journal of Gastroenterology2005,11,41:3

15New model for cardiomyocyte sheet transplantation using a virus-cell fusion technique显示文摘AIM: To facilitate close contacts between transplanted cardiomyocytes and host skeletal muscle using cell fusion mediated by hemagglutinating virus of Japan envelope(HVJ-E) and tissue maceration. METHODS: Cardiomyocytes(1.5 × 106) from fetal rats were first cultured. After proliferation, some cells were used for fusion with adult muscle fibers using HVJ-E. Other cells were used to create cardiomyocyte sheets(area: about 3.5 cm2 including 2.1 × 106 cells), which were then treated with Nile blue, separated, and transplanted between the latissimus dorsi and intercostal muscles of adult rats with four combinations of HVJ-E and/or Na OH maceration: G1: HVJ-E(+), Na OH(+), Cardiomyocytes(+); G2: HVJ-E(-), NaO H(+), Cardiomyocytes(+); G3: HVJ-E(+),Na OH(-), Cardiomyocytes(+); G4: HVJ-E(-), Na OH(-), Cardiomyocytes(-). At 1 and 2 wk after transplantation, the four groups were compared by detection of beating domains, motion images using moving target analysis software, action potentials, gene expression of MLC-2v and Mesp1 by reverse transcription-polymerase chain reaction, hematoxylin-eosin staining, and immunostaining for cardiac troponin and skeletal myosin.RESULTS: In vitro cardiomyocytes were fused with skeletal muscle fibers using HVJ-E. Cardiomyocyte sheets remained in the primary transplanted sites for 2 wk. Although beating domains were detected in G1, G2, and G3 rats, G1 rats prevailed in the number, size, motion image amplitudes, and action potential compared with G2 and G3 rats. Close contacts were only found in G1 rats. At 1 wk after transplantation, the cardiomyocyte sheets showed adhesion at various points to the myoblast layer in the latissimus dorsi muscle. At 2 wk after transplantation, close contacts were seen over a broad area. Part of the skeletal muscle sarcoplasma seemed to project into the myocardiocyte plasma and some nuclei appeared to share both sarcoplasmas.CONCLUSION: The present results show that close contacts were acquired and facilitated the beating function, thereby providing a new cellular transplantation method using HVJ-E and NaO H maceration.Yuto Takahashi Daihachiro Tomotsune Sakiko Takizawa Fengming Yue Mika Nagai Tadayuki Yokoyama Kanji Hirashima Katsunori Sasaki 2015World Journal of Stem Cells2015,7,5:3
16Case of autoimmune hepatitis with markedly enlarged hepatoduodenal ligament lymph nodes显示文摘Autoimmune hepatitis(AIH) is a necroinflammatory liver disease of unknown etiology.The disease is characterized histologically by interface hepatitis,biochemically by increased aspartate aminotransferase and alanine aminotransferase levels,and serologically by increased autoantibodies and immunoglobulin G levels.Here we discuss AIH in a previously healthy 37-year-old male with highly elevated serum levels of soluble interleukin-2 receptor and markedly enlarged hepatoduodenal ligament lymph nodes(HLLNs,diameter,50 mm).Based on these observations,the differential diagnoses were AIH,lymphoma,or Castleman's disease.Liver biopsy revealed the features of interface hepatitis without bridging fibrosis along with plasma cell infiltration which is the typical characteristics of acute AIH.Lymph node biopsy revealed lymphoid follicles with inflammatory lymphocytic infiltration;immunohistochemical examination excluded the presence of lymphoma cells.Thereafter,he was administered corticosteroid therapy:after 2 mo,the enlarged liver reached an almost normal size and the enlarged HLLNs reduced in size.We could not find AIH cases with such enlarged lymph nodes(diameter,50 mm) in our literature review.Hence,we speculate that markedly enlarged lymph nodes observed in our patient may be caused by a highly activated,humoral immune response in AIH.Hideki Fujii Naoki Ohnishi Kazuho Shimura Masafumi Sakamoto Tohru Ohkawara Yoshihiko Sawa Koichi Nishida Yasuo Ohkawara Tatsuro Kobata Kanji Yamaguchi Yoshito Itoh 2013World Journal of Gastroenterology2013,19,11:3

18Performance analysis for power generating system by using matrix method显示文摘We verified that the matrix method, a process analysis method used mainly for life cycle inventory analysis, has several advantages in the analysis of power systems, which have recently become more complex to enhance efficiency and to reduce CO 2 emissions. While designing a conceptual thermodynamic model of a complex power system, the matrix method provides a definite procedure and facilitates calculations, even if there is a recursive loop between the upstream and downstream processes. Similarly, in the case of partial modification to the constructed model, the matrix method can potentially reduce the time and effort required to calculate the thermodynamic balances, even if the constructed model is designed by others. In this study, we obtained mass flow and energy balances of example model power systems by the matrix method from the common thermodynamic conditions including temperatures and pressures which are set on the basis of an existing industrial steam power system. While analyzing the environmental impact of complex multiproduct power systems, such as carbon emissions, the matrix method can be used to easily derive the environmental impact of each final product. We could verify the efficacy of the matrix method in accurately deriving that of an example model power system.Kanji OSHIMA Yohji UCHIYAMA 2011Science China(Technological Sciences)2011,54,7:2
