BACKGROUND Ovarian tumors are common gynecological diseases in children, and the most commonly seen ovarian tumors are germ cell tumors. Robotic surgery is the new access for children ovarian *** SUMMARY From June to October 2017, 4 children with ovarian tumors were admitted and treated in the Department of Pediatric Surgery of People’s Liberation Army General Hospital. The mean age, height, and weight of these patients were 7.5(1-13) years old, 123.75(71-164) cm, and 36.8(8.5-69.5) kg, respectively. Roboticassisted resection of ovarian tumors was performed for all 4 patients. The 3-port approach was used for robotic manipulation. The surgical procedures were as follows. After creation of the pneumoperitoneum, the robotic scope was placed to explore and find the left ovarian tumor. The trocars for robotic arms 1 and 2 were placed at the sites to the lower right and left of the port of the scope. The tumor capsule in the fallopian tube was incised, and the tumor was completely stripped by an electric hook along the junction of the tumor and the capsule. The resected tumor was completely removed using an endobag. The average docking time of the robotic system was 18.5 min, the average operative time was 120 min, and the average blood loss was 20 m L. No drainage tube was placed except in one patient with a mucinous tumor of the ovary. No fever, pelvic fluid, or intestinal obstruction was reported after surgery. No antibiotics were used during the perioperative period, and the average length of hospital stay after surgery was 3 *** Robotic-assisted resection of ovarian tumors is a simple, safe, and effective surgical procedure for selected patients.

在两种介质分界面上引入相位梯度形成相位梯度界面,这将使该界面的出射光和入射光之间产生相移.因此,与普通分界面不同,该界面对光的传播行为有着重大影响.为深入认识梯度相位界面的光学特性,本文研究了光在该类界面上的一般性传播规律.从费马原理出发,采用稳态相位法推导了基于相位梯度界面条件下的二维和三维广义反射和折射定律,该定律表明分界面也会成为影响光传播行为的重要因素,可以作为新的波前调制工具.利用广义反射和折射定律讨论了相位梯度对光传播行为的影响规律,得出了二维和三维情形下的临界条件(全反射和全透射条件),阐明了反射角不等于入射角、异常反射和折射、非平面反射和折射等一些新颖光学现象出现的原因;提出了以相位梯度界面为光学变换核心单元,依据广义反射和折射定律进行光学设计的思路,并以平面透镜和平面轴锥镜为例进行了详细说明与实验验证,实验结果和理论值符合较好,可为拓展广义定律在平面光学设计、自由曲面光学设计以及复杂光束控制中的应用提供参考.

Observation of topological charge transformations in acoustic vortex using passive periodic systems

Science China(Physics,Mechanics & Astronomy) 2025年第1期Mechanics & Astronomy) .卷 140-147页

作者： Di-Chao Chen xie Liu Changqing Xu Da-Jian Wu Ying Cheng xiao-Jun Liu School of Physics and Technology Nanjing Normal University Key Laboratory of Modern Acoustics School of Physics Nanjing University

Vortex transmutation utilizes a periodic system, which not only enables the alteration of the topological charge(TC) of unstable input vortices but also facilitates their transformation into stable structures. This approach is crucial for investigating the characteristics of vortices in various wave systems. Here, we achieve acoustic vortex TC transmutation by employing a welldesigned dual-structured plate external system(DPES). The interactions between the acoustic vortex and the finite-order discrete rotational symmetry lead to the transformation of its topological charge when complete rotational symmetry is broken to Nthorder discrete symmetry. Our results experimentally demonstrate the acoustic vortex TC transmutation based on passive artificial structures, enabling numerous applications in particle manipulation and information multiplexing as well as advancing our understanding and control over free-space acoustic vortices.

Dear Editor, Liver transplantation(LT) is the only curative therapy for patients with endstage liver disease(He et al., 2023; Ling et al., 2022). Post-transplant hypertriglyceridemia(PTHT), which has an incidence of up to 32.8% in 6 months after LT, is one of the major post-transplant complications(Toshima et al., 2020).
