Malignant Priapism Due to Metastatic Papillary Renal Cell Carcinoma : A Case Report

A 70-year-old man presented in December, 2010 with priapism persistent for over a month. The patient had no history of medications for erectile dysfunction, penis trauma, or traumatic sexual activities. A blood gas measurement of the cavernosum was performed, but only fibrosis tissue was aspirated and no blood was obtained. Color-flow Doppler imaging of the penis revealed blood flow in the corpora cavernosa of the penis, suggesting the occurrence of nonischemic priapism. Enhanced chest and abdominal computed tomography revealed a left renal cyst, and the wall of the cyst showed contrast enhancement. No other obvious obstructive mass or tumor was detected in the pelvic cavity. Gradually, necrotic changes of the glans penis appeared, and total penectomy was performed. Histopathological examination of penectomy tissue specimens suggested papillary renal cell carcinoma metastases to the penis. Consequently, open left radical nephrectomy was performed. Pathological diagnosis revealed papillary renal cell carcinoma pT2, and the patient was diagnosed with stage IV (pT2N0M1) renal cell carcinoma. Treatment was provided by intravenous temsirolimus therapy that resulted in partial remission and stable disease, which in turn relieved cancer pain

The growth of Kandelia candel seedlings in mangrove habitats of the Zhangjiang Estuary in Fujian Province,China

通过福建漳江口红树林自然保护区内8个样方24个小样方人工种植600个秋茄胚轴,在3a时间内对秋茄胚轴建立、幼苗生长以及环境因子进行定期观测。研究结果表明:林缘空地的秋茄生长状况良好,白骨壤林内最不利于秋茄幼苗的生长。潮位、盐度、底质土壤理化因子不是造成该样地各样方间秋茄幼苗生长差异的主要原因。动物取食、光照状况以及种间竞争是限制秋茄生长的主要环境因子。秋茄胚轴在长根前易于随潮水漂走,底质土壤中白骨壤致密的根系抑制了秋茄胚轴的定植,导致白骨壤林内秋茄幼苗漂走的数量最多。昆虫和螃蟹等动物的取食是导致林内已经固着生长的秋茄幼苗大量死亡的最主要原因,而林外被取食的幼苗个体极少。此后秋茄幼苗能否继续成长,主要取决于幼苗所接受到的光照条件。3a后,在荫蔽的树冠下,秋茄幼苗无法存活;而在林外,秋茄幼苗已经长成幼树。在林外滩涂上迅速生长的互花米草,也将影响秋茄幼苗的更新和生长。 【英文摘要】 To evaluate the establishment and early growth of the mangrove species Kandelia candel in the intertidal zone,and to develop a better understanding of biotic and abiotic factors influencing the regeneration of its seedlings,we conducted a field experiment in Zhangjiang Estuary in Fujian.Different positions along the intertidal gradient were selected from 20 m to 120 m horizontal distance down the shore,including eight sampling sites in the mangrove areas.Equal numbers(75) numbers of mature propagules of K.c...国家自然科学基金资助项目(30200031);; 福建省自然科学基金资助项目(B0410001)~

Disaster Learning Programme for Elementary School Pupils Through Developing Tsunami Augmented Reality and its Demonstration in the School District

本稿は、泉大津市立浜小学校において、筆者らが実施し、同校の5年生が取り組んだ津波AR制作を通じた防災学習について述べるものである。まず、近年の防災教育が抱える課題について明らかにし、防災教育を3つに類型化した上で取り組むべき防災教育の方向性を示す。次に、浜小学校において2013年度から実施してきた防災教育について紹介し、2020年度に実施した津波AR制作に関する防災教育実践について詳述する。最後に、2020年度の防災教育に関して行った短期的な観点での評価結果についても紹介する
