Background: Testicular atrophy is recurrent after orchidopexy for intra-abdominal cryptorchidism due to damage to vessels. Fowlers-Stephens and Shehata methods proposed staged orchidopexy, but are still associated to a rate of atrophy greater than 10%. Purpose: We set out to present a new technique that preserves testicular vessels. Our study is aimed at investigating testicular vitality after surgery. Patients and Method: We reviewed files of boys who underwent orchidopexy for 2 years in our department. Those who have been operated for intra-abdominal cryptorchidism with the new technique and aged between 6 months and 14 years old were included in our study. We excluded boys who have been operated before 6 months and after 14 years old and those who did not respect their follow-up plane. Ultrasound (US) outcomes were used to measure testicular volumes and blood flow at each postoperative visit. The Sample population was divided into group A and group B representing testes that were followed respectively for 12 and 24 months. Results: 22 boys with 25 testes were included in our study;11 testes in group A and 14 testes in group B. In each group, we noted a significant difference of UDT volumes from the third month after surgery with respective P-values 0.05. There was no statistical difference between UDT and contra lateral testes volumes 12 months after surgery in group A and 24 months in group B with respective P-values of 0.07 and 0.72. All volume differential indexes were Conclusion: This method offers a new perspective in performing safe orchidopexy for intra abdominal undescended testes.

研究源-汇系统对于理解岩石风化、河流输砂、泥砂沉积以及陆地和海洋沉积过程具有重要意义。我国江苏省东海岸具有丰富的沉积物供应,在某些沿海地段形成了一系列沙脊,是进行沉积物源-汇过程研究的理想沉积记录之一。但目前对其物源区来自哪里还未达成共识。我们利用已发表的碎屑锆石U-Pb年龄和钾长石Pb同位素数据,结合江苏沙脊及其周缘区域的数据结果,详细厘定江苏沙脊的物源区,并运用蒙特卡罗反演模型定量评估江苏沙脊潜在物源区对其物质贡献率。结果表明江苏沙脊北部的碎屑物质主要受大别山(45%)和鲁中山区(24%)的共同影响;黄河(29%)、古黄河(27%)和长江(25%)的碎屑物质对江苏沙脊中部的物质组成起重要影响。江苏沙脊南部的物源主要来自长江(68%)。江苏沙脊的出现得益于黄河和长江这样的大陆尺度的大河搬运了丰富的碎屑物质到下游,南黄海西海岸的平坦地貌有利于保存这些碎屑物质,末次冰期后东亚陆架海动力过程(潮汐、海浪和沿岸流等)持续对其改造,这体现了河流-海洋在塑造河口-海岸地貌中的交互作用。

陆地和海洋热容量差异会引起风向和降水发生季节性反转形成季风气候。亚洲是世界上季风气候最典型的区域,同时也有最多的受季风气候影响的人口。季风带来的强降水容易诱发多种次生灾害,严重影响着区域内人类社会生产、居住的安全,因而认识亚洲季风的形成过程至关重要。利用将古论今的地学思想,文章旨在阐述亚洲季风的组成,列举影响亚洲季风形成、演化的主要因素,总结亚洲关键地点的沉积记录显示的南亚季风和东亚季风的演化期次。结果表明,在古近纪,印度板块与亚洲大陆南缘发生碰撞,改变了亚洲的海陆分布,导致青藏高原发生初始隆升,南亚和东亚均出现季风性气候。但此时的东亚地区依然主要受行星风系的控制,东亚季风处于孕育阶段,仅呈条带状局部分布在华南板块的南缘,而南亚季风的覆盖面积相对广泛。这可能主要是因为东亚地区的边缘海打开时间明显要晚于南亚地区海陆分布出现的时间。但随着青藏高原在中新世整体隆升并接近现今的海拔高度,亚洲季风全面进入增强阶段,强烈影响区域内的地质演化过程。自中新世中期以来,由于受控于青藏高原隆升、南北极冰盖的发育,亚洲季风经历了多期次的稳定发展阶段。研究成果为科学合理利用季风开展亚洲系统地球科学研究提供了参考。

A rapid and energy-efficient method was presented for preparing CuO-TiO2 nanotube arrays. TiO2 nanotube arrays were first prepared by anodic oxidation using titanium anode and platinum cathode. Then, the formed TiO2 nanotube arrays and Pt were used as cathode and anode, respectively, for subsequent formation of CuO-TiO2 nanotube arrays, through an electro- chemical process in a solution of 0.1 mol/L CuSO4. The morphology and composition of the CuO-TiO2 nanotube arrays were characterized using field-emission scanning electron microscopy, X-ray photoelectron spectroscopy （XPS）, X-ray diffraction （XRD）, and UV-Vis diffusion reflection spectroscopy （UV-Vis DRS）. XPS and XRD analyses suggested that the Cu element in the nanotubes existed in CuO form, and its content changed along with the voltage during the second electrochemical process. The photocatalytic activities of the CuO-TiO2 nanotube arrays were evaluated by the degradation of a model dye, rhodamine B. The results showed that Cu incorporation aroused wide visible-light adsorption and improved the photocatalytic efficiency of TiO2 nanotube arrays significantly under visible-light irradiation. The stability of the CuO-TiO2 nanotube arrays was also detected.
