Objective: The present study aimed to explore the feasibility and safety of robot-assisted total hysterectomy by transvaginal natural orifice transluminal endoscopic surgery (vNOTES). Methods: In this study, the clinical data of 37 patients who underwent da Vinci robot-assisted total hysterectomy by vNOTES between September 1, 2019 and March 31, 2022 at the Department of Gynecology, the First Affiliated Hospital of Zhengzhou University, China were retrospectively analyzed. Clinical characteristics, operative postoperative complications, surgical outcomes, and postoperative pain scores were collected and analyzed. Results: The average age of the patients included in the study was 47.43 ± 4.44 years. The body mass index (BMI) was calculated using the formula BMI = body weight (kg)/height2 (m2). The average BMI was 23.16 ± 2.72 kg/m2. Among the 37 patients, 30 patients underwent total hysterectomy and bilateral salpingectomy, of which 11 patients underwent ovarian cystectomy simultaneously. Among these 11 patients, three had bilateral ovarian cysts and eight had unilateral ovarian cysts, with the largest cyst diameter measuring 8 cm. The remaining seven patients underwent total hysterectomy and bilateral salpingo-oophorectomy. The average operative time was 86.19 ± 17.83 min, and the estimated intraoperative blood loss was 24.46 ± 15.40 mL, with no intraoperative complications reported. The time to the first postoperative exhaust was 18.51 ± 6.63 h, and the average postoperative length of hospital stay was 3.81 ± 1.05 days. The postoperative visual analog scale (VAS) pain scores were 5.30 ± 0.91 at 24 h after surgery, 3.30 ± 0.70 at 36 h after surgery, and 1.14 ± 0.92 at 48 h after surgery. Only one patient experienced a fever exceeding 38.5 °C, which resolved after receiving antibiotic treatment. Conclusion: The use of the da Vinci robot-assisted total hysterectomy by vNOTES demonstrated safety and offers several advantages. These include reduced surgical trauma, an aesthetic incision, decreased pain, and shorter duration of postoperative exhaust time and hospital stay. These benefits contribute to accelerated postoperative rehabilitation.

X-linked juvenile retinoschisis (XLRS), caused by the mutation of RS1 gene, is one of the most common causes of macular degeneration for male adolescents. The mutations and clinical manifestations of the disease are diverse. Neither the relationship between the genotypes and phenotypes, nor the radical treatment like gene therapy has been found by now. Retrospective studies have shown that carbonic anhydrase inhibitors can help reduce cysts. However, the specifically pharmacological mechanism remains unknown. Here, we culture induced pluripotent stem cells by drawing peripheral blood from a patient with XLRS, which are supposed to facilitate related researches.

X-linked juvenile retinoschisis (XLRS) is an inherited disease characterized by splitting within inner retinal layers and impaired vision, which begins in childhood and occurs mostly in males. Peripheral blood mononuclear cells (PBMCs) were isolated from a seven-year-old boy carrying a hemizygous mutation in RS1 gene, and were reprogrammed into human induced pluripotent stem cells (iPSCs) using non-integrative episomal vectors. The cell line, ZOCi003-A, had normal karyotype, expressed pluripotency markers, and could differentiate into three germ layers in vivo. This IPSC line may be used for studying the molecular basis of XLRS and selecting potential therapeutic targets and drugs.
