研究了Nb—V—Ti微合金化钢中薄板坯（170mm厚）淬火压缩薄板坯工艺（CSP）中的凝固组织、奥氏体和析出物，发现二次枝晶臂间距和奥氏体晶粒尺寸稍大于用CSP生产的类似钢的薄板坯，这主要归功于板坯厚度增加后引起的较慢冷却速度。另一方面，凝固过程中形成的碳氮化物减小了二次枝晶臂间距，但固溶的TiN粒子和合金化元素可以抑制凝固和随后冷却过程中奥氏体晶粒的生长，在CSP薄板坯中除观察到亚枝晶、较大立方体和细小立方体析出物外，在CSP中薄板坯中也发现了枝晶析出物。

世界核心医学期刊文摘（皮肤病学分册） 2006年第11期2卷 46-47页

作者： Moroi y. y.sumoto S. K. Urabe 潘敏 Department of Dermatology Graduate School of Medical Sciences Kyushu University Maidashi 3-1-1 Higashiku Fukuoka 812-8582 Japan

Background: The insulin-like growth factor-1 (IGF-1) receptor (R)-induced phosphatidy.inositol 3-kinase (PI3K)/AKT and mitogen-activated protein kinase (MAPK)/ERK signal transduction cascade, which have critical roles in prevention of apoptosis and regulation of cell cy.le progression, play. an important role in tumorigenesis. The expression of IGF-1R, AKT and ERK1/2 has been described in some human malignancies, but not in extramammary.Paget’s disease (EMPD). Objectives: To study.the expression of IGF-1R, p-AKT and p-ERK1/2 in EMPD and to evaluate the relationships among them. Methods: Thirty.six tissue samples of 34 patients with primary.EMPD were subjected to immunohistochemical staining for IGF-1R, p-AKT and p-ERK1/2. Results: Of thirty.six EMPD tissue samples, 34, 34 and 28 were positive for IGFIR, p-AKT and p-ERK1/2 expression, respectively. 27, 23 and 17 of the 36 specimens stained positive for IGF-IR, p-AKT and p-ERK1/2 in more than half of Paget’s cells, respectively. There were significant correlations between the IGF-1R and p-AKT expression as well as between IGF-1R and p-ERK1/2 expression. Taken together, these results indicate that IGF-1R is overexpressed, and AKT and ERK1/2 are frequently.phosphory.ated in EMPD. Conclusions: Our study.shows that the expression of IGF-1R and the induction of p-AKT and the p-ERK1/2 pathway.ay.play.an important role in the pathogenesis of EMPD. The IGF-IR sy.tem might be a potential therapeutic target in EMPD.

Purpose. We evaluated the use of positron emission tomography.(PET) with fluorine- 18- labeled fluoro- 2- deoxy. d- glucose (FDG) in follow- up study.after radiation therapy.in patients with uterine cervical carcinoma. Materials and methods. Thirty. two studies in 25 patients were reviewed. Twenty.patients were treated with external beam irradiation and intracavitary.brachy.herapy. and five with irradiation following initial surgery. Time frominitial treatment to FDG- PET was 23.3 (5.2- 88.0) months. Rationale for FDG- PET was the presence of sy.ptoms in 6 patients, abnormal serum tumor marker values in 13, abnormal lesions on other diagnostic imaging modalities in 19, and patient request in 2. On visualization of a lesion, the maximum standardized uptake value (maxSUV) of the lesion was calculated, and values over 2.0 were classified as FDG- positive. Maximum tumor diameter and tumor volume in the corresponding disease were estimated by.computed tomography.(CT) or magnetic resonance imaging (MRI). Results. Sensitivity.and specificity.of FDG- PET in the detection of recurrent disease were 91.5% (43/47) and 57.1% (4/7), respectively. Four false negative findings were seen for small lung metastases having a volume less than 1 cm3. Three false- positive cases were a localized pneumonitis, a benign pubic bone fracture,and a fibrosis after interstitial brachy.herapy. Sensitivity.for extrapelvic ly.ph node metastases was extremely.high (100% ); in contrast, sensitivity.and specificity.for lung and bone lesions were 75.0% (12/16) and 33.3% (1/3), respectively. Regarding tumor volume measurement, good correlation between maxSUV on FDG- PET and tumor volume was obtained (lung metastases, P = 0.03; extrapelvic nodes, P y. all corresponding lesions over 1 cm3 showed a maxSUV value greater than 2.0. Conclusion. FDG- PET is a useful tool for the detection of extrapelvic lesions during the follow- up period after radiation therapy.for cervical cancer. T

Background: A keloid is a specific skin lesion that expands bey.nd the boundaries of the original injury.as it heals. Histologically. it is characterized by.the excessive accumulation of collagen. However, the reasons for the expansion and the invasive nature of keloids remain unknown. Objectives: We evaluated collagen degradation and migration by.cultured keloid fibroblasts based on the assumption that these variables were of functional relevance to the expanding and invasive nature of keloid lesions. Methods: Collagen production was investigated by.the detection of ty.e 1 collagen (procollagen ty.e1C peptide: P1P). Matrix metalloproteinase (MMP)-1 (interstitial collagenase) and MMP-2 (gelatinase-A),were investigated as elements of the collagen degradation sy.tem. Enzy.e immunoassay. were performed to measure the production of P1P, MMP-1, MMP-2, and tissue inhibitor of metalloproteinase (TIMP)-1. To assess the production of MMP-2 its gelatinoly.ic activity.was measured by.zy.ography.using gelatin-containing gels. The participation of transforming growth factor-β1 (TGF-β1) in the production and degradation of collagen was also investigated. Finally. the migratory.activity.of keloid fibroblasts was evaluated using a colony.dispersion assay. Results: The production of ty.e 1 collagen, MMP-1, MMP-2, and TIMP-1 by.keloid fibroblasts was 3-fold, 6-fold, 2-4-fold, and 2-fold greater than that of normal dermal fibroblasts, respectively. Production of P1P was increased when TGF-β1 was added to cultures of keloid fibroblasts, while it was decreased when anti-TGF-β1 antibody.was added to the cultures. In contrast, the production of MMP-1 was decreased by.the addition of TGF-β1 to cultured keloid fibroblasts, while it was increased when anti-TGF-β1 antibody.was added to the cultures. The production of MMP-2 increased after treatment with TGF-β1, but did not change significantly.when anti-TGF-β1 antibody.was added to the cultures. Production of TIMP-1 did not change significant

2004年12月26日苏门答腊-安达曼地震(Mw=9)强烈地激发了低频地震简正模式,为改善极低地震简正模式频率及阻尼测量提供了难得的机会。为改进地球一维密度模型,需对低于1mHz的地震简正模式的频率分裂进行精确估算。本次地震中,首次在超导重力仪和地震波记录无叠加的情况下观测到2S1。本文报告来自11个观测台测得的超导重力仪数据的分析。单个观测台的超导重力仪记录频谱清晰地显示了0S2分裂成5个完全可分辨的单线,0S3分裂成7个单线。给出的结果表明超导重力仪可为低频地震模式的精确分析提供高质量数据。

In healthy.subjects, the rate of acid reflux during transient lower esophageal sphincter relaxations (TLESRs) is more frequent at the proximal margin of the L ES. In this study. we investigated the hy.othesis that the rate of acid reflux a t the proximal margin of LES during TLESRs is similar in reflux disease to that in healthy.subjects. Concurrent esophageal manometry.and pH monitoring were perf ormed in the sitting position for 3 hr after a standard meal in 10 patients with reflux disease and 10 agematched healthy.controls. The rate of TLESRs in patien ts with reflux disease (5.0/hr [3.3-6.7]; median [interquartile range])-was si milar to that of controls (4.5/hr [3.7-5.7]). The incidence of acid reflux 7 cm above the LES during TLESRs in patients (48.1%[27.2-71.4%])was significantly.higher than that in controls (10.9%[0.0-18.8%]) but there was no difference 2 cm above the LES (75.0 [69.2-87.5] vs. 74.3 [55.5-90.0%]). The rate of TLES Rs and the incidence of acid reflux during TLESRs are not increased in reflux disease. These findings, therefore, indicat e that reflux disease is not a disorder of TLESRs and relates more to the proxim al extent of the refluxate.
