阿连期奥斯堡层(厚0～80米)是北海北部中侏罗统布伦特组的一套重要的储集层单元,分多个砂质吉尔伯特型三角洲层序组。在中小尺寸(1.5～10米)上,伽玛射线向上变细单元,与单个三角洲层序组相匹配,主要从倾角测井的陡向上倾的趋势中识别出来。在每个层序中,高角度前积层是薄层层状砂岩相(滑塌碎屑流)的典型代表,而低角度前积层、趾积层、底积层形成于块状砂岩相中(砂质碎屑流)。对中等尺寸(大于40米)来说,伽玛射线显示了叠加三角洲层序组中的向上变细趋势或向上变粗趋势,按照相对海平面升高时加积或退积速率为代表来解释这些井间趋势。砂质碎屑流沉积的相对丰度反映三角洲的前积斜坡上部的明显周期性不稳定性,也许这期间三角洲前缘水体深度增加了。然而,单个吉尔伯特型层序组的正常海进沿水下同一海拔深度进行,这期间海水深度有一点或没有变化。这种已被我们观察到的长期变化产生的垂直叠加的三角洲层序组是普通的相对海平面上升的一部分。海平面上升模式按步进方式解释为顶积层的变化。奥斯堡层下覆的霍达地台上准克层向东削蚀的推进暗示陆块向上抬升,前奥斯堡三角洲为海平面低水位。因此奥斯堡层被认为是海平面上升和沉积物相对大量供给时发育起来的低水位楔。在最新的阿连洪泛面,隆起被认为是上覆诺兰其层的基底。倾角测井,综合岩心资料及其他测井数据,是正确解释储集层内部结构的关键。斜坡调整模式预测奥斯堡型叠加的块状储集砂岩的沉积发生在局部的高沉降区或是同生断层发育区,或是有断崖存在的背流深水区。

Pneumoscrotum: A rare manifestation of perforation associated with therapeutic colonoscopy

World Journal of Gastroenterology 2005年第32期11卷 5061-5063页

Pneumoscrotum is uncommon and also rarely reported as a complication associated with colonic perforation. A case of colonic perforation in delayed fashion associated with EMR, revealed by pneumoscrotum, is reported and the associated literatures are reviewed. A 52-year-old male received piecemeal EMR for a laterally spreading tumor 35 mm in size in our hospital. He complained of enlargement of the scrotum and revisited our hospital the day after the procedure. A diagnosis of pneumoscrotum was made, and as most such cases have been reported to be associated with pneumoperitoneum, colonic perforation was suspected. Free air but no fluid collection was found by abdominal computed tomography, and delayed colonic perforation was diagnosed. However, as there were no clinical signs of peritoneal irritation,conservative treatment was administered and the patient recovered uneventfully. Pneumoscrotum could be a sign of colonic perforation after EMR, and treatment should be carefully chosen.

Successful Combination Therapy of Nivolumab and Radiation for Massive Mucosal Melanoma in Patient with Autoimmune-Myasthenia Gravis, Systemic Lupus Erythematosus and Rheumatoid Arthritis

A 58-year-old woman complicated with autoimmune diseases of myasthenia gravis (MG), rheumatoid arthritis, and systemic lupus erythematosus noticed an irregular black macule on her bilateral major labia, which was diagnosed as malignant melanoma. The melanoma lesion involving the vagina, uterus, and ventral side of rectum was not operable and was treated with nivolumab and concurrent radiotherapy with good control of the MG. This resulted in remarkable tumor shrinkage, possibly due to synergistic effects of both treatments. To our knowledge, few reports have described the effectiveness of combination therapy with nivolumab and radiation for malignant melanoma. The present case showed an enhanced anti-tumor effect with combination therapy.

电子纸(EPD)技术有一些瑕疵,缺乏市场成熟性。电子纸用户是少数,围绕EPD的生态体系和下层基础构建还在发展中。比如LCD显示器拥有众多的标准驱动电路支持,但可以设想,EPD的瑕疵会随着市场的发展而淡化。EPD的其它缺陷还包括有电压要求:即高压驱动(>10V),尽管驱动电流非常低。随着时间推移EPD比其它显示媒介缩短了响应时间。当然,尽管存在这些缺点,但都会在将来得到改正,EPD为各种创新应用提供了独到的方案。分段式EPD凭据其超薄、不规整性、柔韧性能,可为各种类型的显示器提供高对比显示。通过运用低功耗电子系统来匹配低功耗图形显示,设计师可以实现产品便携和长寿电池的双重性能。

Huge Sacrococcygeal Teratoma in an Adult Female: A Case Report

引用

Journal of Cancer Therapy 2019年第3期10卷 197-202页

作者： Yasutake Uchima Naoki Aomatsu Takuma Okada Hironari Miyamoto Gen Tsujio shigeaki Kurihara Toshiki Hirakawa Takehiko Iwauchi Junya Morimoto Kazuhiro Takeuchi Department of Surgery Fuchu Hospital Izumi Osaka Japan

Background: Teratomas are a type of germ cell tumor, which are mostly benign, and dominative in adult females. Sacococcygeal teratomas are usually found in newborns or children, and can be detected prenatally;they are exceedingly rare in adults. We reported a case of a sacrococcygeal teratoma in adult female. Case presentation: A 26-year-old female was diagnosed with a presacral tumor 6 years ago. Pelvic computed tomography (CT) demonstrated a presacral heterogeneous tumor, containing multi-located cystic area and enhanced solid component with calcification. Magnetic resonance imaging (MRI) showed a presacral non-enhanced cystic lesion with solid component, 128 mm × 104 mm × 102 mm, which was suspected of having invaded the rectal wall, fifth sacral vertebra (S5), and coccyx. She underwent abdomino-sacral total excision of tumor with coccygectomy. Histopathological examination revealed a tumor with intricate admixture of ectodermal (epidermis, sebaceous glands and squamous), mesenchymal (cartilage, adipose tissue, blood vessels, nerves and skeletal muscle) and endodermal components (respiratory epithelium and intestinal epithelium) respectively. After 24 months of follow-up the patient was both clinically and radiologically disease free. Conclusions: Early complete excision was the preferred definitive modality of treatment for sacrococcygeal teratoma, and multi-staged excision and reconstruction resulted in successful and safe treatment in our case.

Association of Renal Volume with the Degree of Aortic Contrast Enhancement in Abdominal CT

引用

Advances in Computed Tomography 2013年第2期2卷 55-62页

作者： Natalia S. muto Tamotsu Kamishima Tsukasa Sasaki Satoshi Terae Khin Khin Tha Hiroki Shirato Kyongtae T. Bae Department of Clinical Support for Medical Practice Hokkaido University Hospital Sapporo Japan Department of Diagnostic Radiology Hokkaido University Hospital Sapporo Japan Department of Radiation Medicine Hokkaido University Graduate School of Medicine Sapporo Japan Department of Radiology University of Pittsburgh School of Medicine Pittsburgh USA Faculty of Health Science Hokkaido University Sapporo Japan

To assess the correlation of renal volume measured on CT with aortic contrast enhancement on the hepatic arterial phase of dynamic CT, 64 consecutive patients (34 men, 30 women) were retrospectively examined. Renal volumes were measured on CT. The aortic contrast enhancement was inversely correlated with renal medullary volume (r = -0.52, p 0.0001), and renal cortical volume (r = -0.3, p = 0.02). Renal volume may have inverse correlation with aortic contrast enhancement on the hepatic arterial phase of dynamic CT. This might call for adjustment of contrast material dose based in part on renal volume in the future.
