The authors have recently proposed a degradative solvent extraction method to upgrade and fractionate various types of lowrank coals into several fractions at around 350 °C. The low-molecular-weight fraction which was recovered as solid(termed soluble) was free from ash and moisture, had yield of 23.5 – 61.0 wt% on carbon basis, molecular weight of around 300, carbon content of as high as 81.5 – 84.8 wt% and oxygen content of as low as 6.5 – 12.1 wt%. In this work the combination of the proposed extraction method and liquefaction of the soluble under mild condition as a two-stage treatment method to produce liquid fuel was initially investigated. A lignite(LY) was extracted by the proposed extraction method. The solubles obtained were then liquefied at 380 and 400 oC by using FeO OH/sulfur as catalyst under the H2 pressure of as low as 2 MPa(at room temperature). The results showed that as high as 27.3 % of carbon in the LY was converted as soluble by the extraction. 55.4 wt% of LY soluble was then converted as liquid fraction(oil) excluding H2 O by liquefaction. It is worth noting that much more oxygen was removed as H2 O rather than CO2 during the two-stage treatment compared with the direct liquefaction of the raw material. Most of the CO2 and H2 O from the two-stage treatment were formed at extraction stage, and the yields of soluble liquefaction were much smaller than those of the direct liquefaction of raw materials. The oxygen content of the oil from LY soluble liquefaction was 3.9 wt%, much lower than that from the direct liquefaction of the raw material. Also, the chemical composition of the oil from soluble liquefaction was significantly different with the oil from the direct liquefaction of raw material. It was found that the CO2 emission and H2 consumption of the two-stage treatment were significantly less than those of the direct liquefaction of raw material. Also, the mass transfer of soluble liquefaction was much easier than that of the direct liquefa

教材是文化传承、意识渗透的物质载体。教材建设是国家事权,更是提升教育质量的基本保障。从日本现行教材管理体系而言,权责明确的教材管理主体、具有研究性质的教材保障协会、分学段开发的众多教材出版公司并存的维稳格局,确保当前日本教材发展的科学高效、稳定持续。同时,日本教材建设也面临因成本巨大、出生率低等社会倾向而出现的教材发行供应公司和教材代售店大量倒闭的困境。对此,日本教材建设在坚持原则、深化发展和勇于创新的基础上,衍生出教材免费供给、低价提供、增加页数、完全供给、无障碍化教材和数字化教材等六大发展趋势,并与社会责任传递、社会公益发展、个性化成长、教材质量提升、人文关怀塑造、智能时代适应等相融合。

作者： Yasushi Yoshimatsu Akihiro Yamada ryuichi Furukawa Koji Sono Aisaku Osamura Kentaro Nakamura Hiroshi Aoki Yukiko Tsuda Nobuo Hosoe Nobuo Takada Yasuo Suzuki Department of Internal Medicine Faculty of MedicineToho University Toho University Sakura Medical Center

AIM: to evaluate the effectiveness of probiotic therapy for suppressing relapse in patients with inactive ulcerative colitis(UC).METHODS: Bio-Three tablets, each containing 2 mg of lactomin(Streptococcus faecalis T-110), 10 mg of Clostridium butyricum TO-A, and 10 mg of Bacillus mesentericus TO-A, were used as probiotic *** outpatients with UC in remission were randomly assigned to receive 9 Bio-Three tablets/day(BioThree group) or 9 placebo tablets/day(placebo group)for 12 mo in addition to their ongoing *** symptoms were evaluated monthly or on the exacerbation of symptoms or need for additional medication. Fecal samples were collected to analyze bacterial DNA at baseline and 3-mo intervals. Terminal restriction fragment length polymorphism and cluster analyses were done to examine bacterial components of the fecal ***: Forty-six patients, 23 in each group,completed the study, and 14 were excluded. The relapse rates in the Bio-Three and placebo groups were respectively 0.0% vs 17.4% at 3 mo(P = 0.036), 8.7%vs 26.1% at 6 mo(P = 0.119), and 21.7% vs 34.8%(P = 0.326) at 9 mo. At 12 mo, the remission rate was 69.5% in the Bio-Three group and 56.6% in the placebo group(P = 0.248). On cluster analysis of fecal flora, 7 patients belonged to cluster Ⅰ, 32 to cluster Ⅱ,and 7 to cluster Ⅲ.CONCLUSION: Probiotics may be effective formaintaining clinical remission in patients with quiescent UC, especially those who belong to cluster Ⅰ on fecal bacterial analysis.

Interferon augments the anti-fibrotic activity of an angiotensin-converting enzyme inhibitor in patients with refractory chronic hepatitis C

引用

World Journal of Gastroenterology 2006年第42期12卷 6786-6791页

作者： Hitoshi Yoshiji ryuichi Noguchi Hideyuki Kojima Yasuhide Ikenaka Mitsuteru Kitade Kosuke Kaji Masahito Uemura Junichi Yamao Masao Fujimoto Masaharu Yamazaki Masahisa Toyohara Akira Mitoro Hiroshi Fukui Third Department of Internal Medicine Nara Medical University Nara Japan

AIM: To evaluate the effect of combination treatment with the interferon (IFN) and angiotensin-converting enzyme inhibitor (ACE-Ⅰ) on several fibrotic indices in patients with refractory chronic hepatitis C (CHC). METHODS: Perindopril (an ACE-Ⅰ; 4 mg/d) and/or natural IFN (3 MU/L; 3 times a week) were administered for 12 mo to refractory CHC patients, and several indices of serum fibrosis markers were analyzed. RESULTS: ACE-Ⅰdecreased the serum fibrosis markers, whereas single treatment with IFN did not exert these inhibitory effects. However, IFN significantly augmented the effects of ACE-Ⅰ, and the combination treatment exerted the most potent inhibitory effects. The serum levels of alanine transaminase and HCV-RNA were not significantly different between the groups, whereas the plasma level of transforming growth factor-b was significantly attenuated almost in parallel with suppression of the serum fibrosis markers. CONCLUSION: The combination therapy of an ACE- Ⅰand IFN may have a diverse effect on disease progression in patients with CHC refractory to IFN therapy through its anti-fibrotic effect.
