AIM： to determine the efficacy of an interferon alpha and ribavirin combination treatment for Japanese patients infected with hepatitis C virus （HCV） of genotype 2, a multi-center study was retrospectively analyzed. MEtHODS： In total, 173 patients with HCV genotype 2 started to receive interferon-alpha subcutaneously thrice a week and 600-800 mg of ribavirin daily for 24 wk. RESULtS： the overall sustained virological response （SVR）, defined as undetectable HCV RNA in serum, 24 wk after the end of treatment, was remarkably high by 84.4%, （146/173） by an intention-to-treat analysis. A significant difference in SVR was found between patients with and without the discontinuation of ribavirin （46.9% vs 92.9 %）, but no difference was found between those with and without a dose reduction of ribavirin. A significant difference in SVR was also found between patients with less than 16 wk and patients with 16 or more weeks of ribavirin treatment （34.8 % vs 92.0 %）. CONCLUSION： the 24-wk interferon and ribavirin treatment is highly effective for Japanese patients with HCV genotype 2. the significant predictor of SVR is continuation of the ribavirin treatment for up to 16

Introduction: the purposes were to clarify the magnetic resonance imaging (MRI) findings of malignant ovarian lesions arising from endometriomas, and to compare the lesions’ histopathology and MRI characteristics. Materials and Methods: Between May 2004 and December 2012, 140 patients, all of whom were diagnosed as having an endometrioma by using MR imaging, underwent surgery. We compared the MR characteristics including size and signal intensity of the tumor and mural nodules, the thickness of the septum, and the thickness of the wall with the pathological diagnoses. the attached angles of the mural nodules to the cyst wall were also evaluated. Results: Among the 179 lesions, preoperative MR imaging diagnosed 153 benign and 26 malignant. Based on the pathological results, 169 were diagnosed as benign and 10 were diagnosed as malignant. Finally, preoperative MR imaging correctly diagnosed 152 benign (group 1) and nine malignant (group 2), misdiagnosed 17 benign as malignant (group 3) and misdiagnosed one malignant as benign (group 4). As for mural nodules, there was a significant difference between groups 1 and 2 in the mean maximum diameter of the mural nodules. An acute attached angle was shown in 1 of 7 in group 1, in 11 of 16 in group 2, and in 14 of 22 in group 3. We also compared benign group with malignant group on the final pathological findings. As for mural nodules, there was a significant difference between groups 1 + 3 and group 2 in the mean maximum diameter of the mural nodules. On dynamic study, there were 22 enhanced mural nodules (75.9%) on group 1 + 3. Conclusion: Most of endometriomas preoperatively diagnosed as benign were pathological benign lesions. Endometriomas that contain many enhanced mural nodules with papillary shape, larger size, showing hypointense on t1WI, hyperintense on t2WI and showing an acute attached angle may have malignant potential.

为了应对能源安全危机和全球环境变化,汽车发动机需要提高燃油经济性并且适应各个国家更加严格的尾气排放法规。为了使发动机在具有低油耗的同时获得高性能,对其基本内部设计如缸体、缸盖都进行了改进,燃烧速度也有较大的提高。同时,对行程缸径比和气门布局方案也进行了优化。同时,进气道的流量系数和进气滚流比也通过采用激光堆焊气门座而得以提高。另外,也采用了众多先进技术。使用新型电动可变气门正时的阿特金森循环和采用新型多孔式直接喷射喷油器的新燃烧技术提高了发动机功率、燃油经济性,并降低了排放。采用电动水泵和开关阀的可变冷却系统,通过缩短暖机时间和降低机械损失提高了燃油经济性。同时,新开发的可变机油泵极大地降低了摩擦损失。通过采用此类先进技术,新款2.5 L自然吸气发动机的热效率超过了40%,功率超过了150 kW。发动机匹配8速自动变速器,油耗降低达16%以上。

近年来在日本，人们逐渐认识到一种常常是可逆的，原因不明的脑炎，多见于年轻女性且后果严重。这种脑炎被称为急性播散性淋巴细胞脑炎、急性可逆性边缘叶脑炎、急性青年女性非疱疹脑炎、青年急性非疱疹脑炎等。目前尚不能证明该种脑炎与感染、肿瘤或非特异性自体免疫相关。研究人员发现这种脑炎与卵巢畸胎瘤相关脑炎的临床表现类似，而后者被认为是相关性副肿瘤综合征，并与N-甲基-D-天冬氨酸（NMDA）受体的NR1／NR2亚基抗体存在有关。
