Ayant adopté une position pro-maoïste pendant les années 1970, Philippe Sollers part en Chine pendant 3 semaines en 1974 pour témoigner du grand succès de la Révolution culturelle (1966-1976). Selon l’écrivain, directeur de la revue Tel Quel, la révolution doit passer par l’écriture et par la théorie. Néanmoins, la Chine qu’il découvre durant le séjour semble s’éloigner de la Chine rêvée avant le départ… En s’appuyant sur des articles publiés par Tel Quel, notre étude cherche à montrer comment la Chine de Mao, idéalisée par un discours idéologique, se transforme en un réel théâtralisé que le peuple chinois est obligé de mettre en scène devant les touristes qui sont autorisés à visiter la Chine. Having adopted a pro-Maoist position during the 1970s, Philippe Sollers went to China for three weeks in 1974 to witness the great success of the Cultural Revolution (1966-1976). According to the writer, director of the magazine Tel Quel, the revolution must be achieved through writing and theory. Nevertheless, the China he discovered during his stay seemed to be far from the China he had dreamt of before his departure... Based on articles published by Tel Quel, the paper seeks to show how Mao's China, idealized in ideological discourse, is transformed into a dramatized reality that the Chinese people are obliged to stage in front of the tourists allowed to visit China.

This paper presents the design and development of a multiple-inputmultiple-output (MIMO) compact antenna with coplanar waveguide (CPW) feed for 5G millimeter-wave applications. It can be operated in the C (4-8 GHz), Ku (12-18 GHz), K (18-26.5 GHz), and Ka (27-40 GHz) with full coverage of the millimeter wave 5G New Radio (NR) n257/n258/n261 bands.The proposed antenna is designed with planar geometry with an element size of 14 mm×19 mm, which makes it compact and achieves a wide operating bandwidth. By the arrangement of orthogonal rotation, the 4-port structure is formed to realize good polarization diversity. The result shows that the MIMO antenna has a stable radiation pattern at the low-frequency band and offers an ultra-wide bandwidth (UWB) of 5-39 GHz (154.5%), isolation of more than 19 dB, and a total footprint of 40 mm×40 mm.

Background: Left paraduodenal hernia (PDH) is a mesenterico-parietal hernia with retroperitoneal retrocolic herniation of the small bowel into a sac formed by a peritoneal fold located near the fourth portion of the duodenum. It’s a rare cause of hydronephrosis by compressed the upper left ureter. Traditionally, PDH are treated by laparotomy.Case presentation: An 8-year-old boy’s primary purpose was the treatment of cryptorchidism. But hydronephrosis was detected and it was induced by left paraduodenal hernia. Diagnostic laparoscopic exploration confirmed the diagnosis left paraduodenal hernia secondary hydronephrosis. Cryptorchidism was the primary purpose of treatment. The patient was treated with laparoscopic surgery, fixed left paraduodenal hernia, released the ureteropelvic junction obstruction (UPJO) and treated hydronephrosis.Conclusion: Secondary surgery for treating cryptorchidism would be performed and the long-term follow up was necessary.This case suggests us a rare cause of hydronephrosis in children. Every why has a wherefore. We must pay much attention to any unusual details in our medical work even though these details aren’t related to our primary objects.

Objective: To evaluate safety and efficacy of a novel method of bilateral patent processus vaginalis ligation in transumbilical single-site multiport laparoscopic orchiopexy for children. Methods: A retrospective study was carried out comparing the novel ligation and conventional ligation performed by a single surgeon between July, 2017-July, 2018. The patients were divided into the novel group (42 cases) and the conventional group (59 cases). In the novel group, transumbilical single-site multiport laparoscopic orchiopexy was performed and the bilateral internal rings was stitched with "8" pattern suture. In the conventional group, the conventional TriPort laparoscopic orchiopexy was performed and purse string suture was used to fix the internal rings. The parameters of operative duration time, postoperative hospital stay; postoperative complications were compared between 2 groups. Results: All operations were successful. No Perioperative period complications were found and all patients were discharged within 4-6 days after operation. There is no statistic difference in the surgery time and hospitalization day. However, there is significant difference in the Pain face scale scores after day 2(1.60±0.73 VS 2.02±0.86). And there is no scar and the satisfactory cosmetic could be seen in scrotum and inguinal area in the novel group. Conclusion: The novel ligation was safety and efficacy. It is relatively easy to perform with smaller scar and less pain. We propose the novel ligation as a more viable treatment option for pediatric cryptorchidism with bilateral patent processus vaginalis.
