Objective To explore the feasibility of magnetic compression technique (MCR) in the treatment of severe single mid-ureteral stricture in a rabbit model. Methods After 10 female New Zealand rabbits were selected, the distal end of the right ureter was ligated with silk thread. Two weeks after the operation, when the right ureter was dilated, the mid-ureter was ligated again with silk thread to create a severe single mid-ureteral stricture animal model. Longitudinal incisions were made at the upper and lower ends of the ligation site, and cylindrical NdFeB magnets with central holes (sub-magnets and main magnets) were placed to anastomose and recanalize the mid-ureteral stricture. The magnets were adjusted to the appropriate position to automatically align and attract each other. The longitudinal incision sites of the ureter were sutured with 6-0 Prolene thread, and the abdominal cavity was closed layer by layer. The operation time was recorded. X-ray films were taken every two days to confirm the position of the magnets and record the time of magnet detachment. Three weeks after the operation, the anastomotic specimens were obtained, and the formation of the anastomosis was evaluated with gross observation and histological staining. Results Two weeks after ligation, all experimental rabbits showed obvious dilation of the right ureter. The mid-ureteral ligation and placement of the male and female magnets were successfully completed in all 10 experimental rabbits, with an operation time of (24.00±5.15)minutes. The male and female magnets attracted each other well. X-ray examination showed that the magnets detached and entered the distal ureter (14.0±1.9) days after magnetic compression. The recanalization of the severe single mid-ureteral stricture was successfully achieved. The gross specimens and histological examination of the anastomosis showed that the anastomosis remained patent and the mucosal healing was good. All experimental rabbits survived well after the operation without serious complications. Conclusion MCT provides a new idea and novel method for the treatment of mid-ureteral stricture. This study confirmed the feasibility of this technique in treating severe single mid-ureteral stricture in a rabbit model. The operation is relatively simple and has potential for clinical application.

[Objective] To explore the clinical features of IgG4-related urinary diseases so as to provide reference for the diagnosis and treatment of such diseases. [Methods] The clinical data of 4 cases of IgG4-related urinary system diseases diagnosed and treated in Xijing Hospital of Air Force Medical University during Aug.2019 and Dec.2023 were retrospectively collected.Here, we report on the diagnosis and treatment of these patients, analysing their symptoms, serology, imaging and pathology as well as their treatment and outcomes. [Results] The patients included 2 male and 2 female.The lesions were involved with the retroperitoneum and urinary system.Three patients had symptoms of lumbar pain.The imaging manifestations were complex, including retroperitoneal mass involving urinary system organs in 2 cases, tabdense shadow of the right kidney in 1 case, and simple cystic mass of kidney in 1 case.Serum IgG4 value was not detected before surgery.All patients underwent radical surgical treatment.Postoperative pathology showed fibrous tissue hyperplasia with a large number of plasma cells, lymphocytes, a few neutrophil infiltrates, and lymphoid follicles and obliterated vasculitis in some specimens.The number of IgG4⁺ plasma cells was more than 10 in all tissues under high power microscope.After surgery, 3 patients had symptoms improved, and serum IgG4 value was within the normal range; 1 patient (patem 3) had elevated IgG4 value during follow-up, received subsequent hormone therapy, and the serum IgG 4 level remained stable. [Conclusion] The symptoms of IgG4-related diseases involving the urinary system are non-specific, and the imaging findings are various, easily confused with other diseases.Early detection of serum IgG4 and biopsy pathology can help clinicians make correct diagnosis in the early stage.

OBJECTIVE To evaluate the efficacy， safety and cost-effectiveness of dupilumab in the treatment of severe asthma with rapid health technology assessment （HTA）， and to provide evidence-based evidence for clinical treatment. METHODS Retrieved from PubMed，Cochrane Library，CNKI，Wanfang， VIP database， and other related websites of HTA. HTA reports， systematic review/meta-analysis， and economic studies of dupilumab in the treatment of severe asthma were collected. Researchers independently identified literature， extracted data， and assessed the quality of included studies. Qualitative description was performed. RESULTS A total of 15 pieces of literature were included， involving 9 systematic reviews/meta-analyses and 6 economic studies. In terms of effectiveness， dupilumab was significantly better than placebo. Compared with other biological drugs， in the patients with severe asthma aged 12 years and above， for those with eosinophil （EOS） ≥300 cells/μL， dupilumab ranked first in improving forced expiratory volume in one second （FEV1）， outperforming tezepelumab， benralizumab， and mepolizumab. It ranked second in reducing acute exacerbations， surpassed only by tezepelumab， while its effect on improving asthma control questionnaire score was relatively lower， being better only than benralizumab. For those with 150 cells/μL ≤EOS＜300 cells/μL， dupilumab was superior to mepolizumab in reducing asthma exacerbation， while the effect on FEV1 was weaker than benralizumab and mepolizumab. In terms of safety， there was no significant difference in the incidence of adverse events and serious adverse events between dupilumab and placebo or other biological drugs， while the incidence of injection site reactions of dupilumab was significantly higher than placebo. In terms of cost-effectiveness， the research results of different countries were not consistent， and there was a lack of research data from China. CONCLUSIONS Dupilumab is an effective and safe choice in the treatment of severe asthma， and its cost-effectiveness requires further research based on China’s medical environment to be determined.

BACKGROUND: The primary limitation to kidney transplantation is organ shortage. Recent progress in gene editing and immunosuppressive regimens has made xenotransplantation with porcine organs a possibility. However, evidence in pig-to-human xenotransplantation remains scarce, and antibody-mediated rejection (AMR) is a major obstacle to clinical applications of xenotransplantation. METHODS: We conducted a kidney xenotransplantation in a brain-dead human recipient using a porcine kidney with five gene edits (5GE) on March 25, 2024 at Xijing Hospital, China. Clinical-grade immunosuppressive regimens were employed, and the observation period lasted 22 days. We collected and analyzed the xenograft function, ultrasound findings, sequential protocol biopsies, and immune surveillance of the recipient during the observation. RESULTS: The combination of 5GE in the porcine kidney and clinical-grade immunosuppressive regimens prevented hyperacute rejection. The xenograft kidney underwent delayed graft function in the first week, but urine output increased later and the single xenograft kidney maintained electrolyte and pH homeostasis from postoperative day (POD) 12 to 19. We observed AMR at 24 h post-transplantation, due to the presence of pre-existing anti-porcine antibodies and cytotoxicity before transplantation; this AMR persisted throughout the observation period. Plasma exchange and intravenous immunoglobulin treatment mitigated the AMR. We observed activation of latent porcine cytomegalovirus toward the end of the study, which might have contributed to coagulation disorder in the recipient. CONCLUSIONS 5GE and clinical-grade immunosuppressive regimens were sufficient to prevent hyperacute rejection during pig-to-human kidney xenotransplantation. Pre-existing anti-porcine antibodies predisposed the xenograft to AMR. Plasma exchange and intravenous immunoglobulin were safe and effective in the treatment of AMR after kidney xenotransplantation.

Objective To investigate the impact of two different surgical methods, orthotopic kidney transplantation and abdominal heterotopic kidney transplantation, on the surgical outcomes of pig-to-pig kidney transplantation and the short-term survival of recipient pigs after surgery. Methods Twenty-four Bama miniature pigs were divided into two groups, with 12 pigs in each group, and underwent orthotopic kidney transplantation and abdominal heterotopic kidney transplantation, respectively. The perioperative indicators of the recipient pigs, renal blood perfusion, the overall incidence rate of complications and survival rate were compared between the two surgical methods. Results The total surgical time, renal artery anastomosis time, renal vein anastomosis time, cold ischemia time and total ischemia time were all shorter in the abdominal heterotopic kidney transplantation group than in the orthotopic kidney transplantation group, with statistically significant differences (all P<0.05). The number of satisfactory renal perfusion cases was higher in the abdominal heterotopic kidney transplantation group than in the orthotopic kidney transplantation group (83% vs. 75%), but the difference was not statistically significant (P>0.05). The total incidence of postoperative complications was 33% in the heterotopic kidney transplantation group, with a survival rate of 92%, and the cause of death was rupture of the vascular anastomosis. The total incidence of postoperative complications was 50% in the orthotopic kidney transplantation group, with a survival rate of 83%, and the causes of death were renal vein thrombosis and renal artery thrombosis. There were no statistically significant differences in the total incidence of postoperative complications and survival rates between the two groups (all P>0.05). Conclusions Compared with orthotopic kidney transplantation, abdominal heterotopic kidney transplantation showes better surgical outcomes in pig-to-pig kidney transplantation and is more beneficial for the short-term survival of recipient pigs after surgery. This provides experience for improving the stability of pig-to-non-human primate kidney xenotransplantation models in the future.
