Objective:To evaluate the feasibility of transjugular transcatheter tricuspid valve replacement (TTVR) using the LuX-Valve Plus system (Ningbo Jenscare Scientific, China) for the treatment of severe tricuspid regurgitation in real-world clinical settings.Methods:This prospective study enrolled 81 patients with severe ricuspid regurgitation (≥3+) who underwent TTVR with the LuX-Valve Plus system at the Department of Cardiology, West China Hospital of Sichuan University between May 2022 and March 2024. Among them, 44 patients were from a compassionate-use study, and 37 were from two premarket clinical trials. Baseline clinical data, preprocedural imaging, procedural outcomes, and postprocedural follow-up data were collected. The primary endpoint events included device success, procedural success, and 30 d composite adverse events.Results:The age of the cohort was (74.5±7.8) years, with 54 females (67%). Device success and procedural success rates were both 90% (73/81). Post-procedural tricuspid regurgitation improved, with a 6% (5/81) incidence of moderate-to-severe paravalvular leakage. The rate of permanent pacemaker implantation was 12% (10/81), of which 5% (4/81) had pre-existing indications for pacemaker implantation. Major bleeding events occurred in 10% (8/81) of patients, and the 30 d composite endpoint rate was 25% (20/81).Conclusion:TTVR using the LuX-Valve Plus system demonstrates promising feasibility for high-risk surgical patients with severe tricuspid regurgitation, effectively reducing or eliminating regurgitation with acceptable safety. However, challenges remain in reducing risks of major adverse events, including permanent pacemaker implantation and severe bleeding.

Objectives:To investigate the feasibility of using bedside echocardiography on the evaluation of potential donors with different causes of brain death for adult heart transplantation. Methods:Bedside echocardiographic and clinical data of consecutive potential donors for adult heart transplantation evaluated by the team of our institution from February 2018 to December 2020 were retrospectively analyzed.Based on different causes of brain death,the potential donors were divided into stroke(ischemic or hemorrhagic,n=398)and non-stroke(head trauma,brain tumor,anoxia,n=272)groups.The clinical and echocardiographic features were compared between the two groups.A total of 350 donors were assigned to our hospital by the China Organ Transplant Response System and met the inclusion criteria for donor selection.There were 195 cases in the stroke group and 155 in the non-stroke group.Retrieval operations were performed and the retrieval rate of hearts for transplantation in stroke donors was compared to that in non-stroke donors. Results:(1)Among the 670 potential heart donors,compared with the non-stroke group,donors in the stroke group were significantly older,had higher body mass index,larger left ventricular end-diastolic diameter,thicker interventricular septum,higher rates of echocardiographic abnormalities,higher prevalence of hypertension(all P<0.001).Among the 670 potential heart donors,17.5%(117 cases)did not meet the echo selection criteria,the common causes were left ventricular hypertrophy(59 cases,50.4%),left ventricular ejection fraction<50%(27 cases,23.1%),wall motion abnormalities(21 cases,17.9%),and left ventricular dilation(14 cases,12.0%).(2)Among the 350 donors who had met the selection criteria and assigned to our hospital by the China Organ Transplant Response System and underwent retrieval operation,70.3%(246 cases)were successfully procured,110 cases(44.7%)in the stroke group and 136 cases(55.3%)in the non-stroke group.The retrieval rate of stroke donors(110/195,56.4%)was lower compared with that of non-stroke(136/155,87.7%,P<0.001),104 cases(29.7%)were not retrieved,and the leading cause of unsuccessful organ retrieval was the occlusion of at least one major coronary artery(91 cases,87.5%). Conclusions:Bedside echocardiography is of great value as a screening tool for cardiac donors.Cardiac structures of the potential donor with stroke as the cause of brain death were different from those with non-stroke causes.The retrieval rate of stroke donors was lower than that of non-stroke donors,even if the initial criteria for donor selection were fulfilled.

Robotic surgery is known as the"third technological revolution"in the field of surgery,and is an important milestone in the development of modern surgery.However,our country's innovative surgical robot industry is still in its early stages,and it is only being utilized in certain surgical fields.To explore the effectiveness of the application of do-mestic surgical robot in oral and maxillofacial surgery,the author successfully completed a case of benign parotid tumor resection with the assistance of a domestic autonomous robot.The operation was successful,facial nerve function was preserved,and postoperative wound healing was good.

Diabetes mellitus(DM)is a major metabolic disease endangering global health,with diabetic ne-phropathy(DN)as a primary complication lacking curative therapy.Sporoderm-broken spores of Ganoderma lucidum(GLP),an herbal medicine,has been used for the treatment of metabolic disorders.In this study,DN was induced in Sprague-Dawley rats using streptozotocin(STZ)and a high-fat diet(HFD),and the protective mechanisms of GLP were investigated through transcriptomic,metabolomic,and network pharmacology(NP)analyses.0ur results demonstrated that GLP intervention ameliorated renal damage and inflammation levels in DN rats.Integrative metabolomic and transcriptomic analysis revealed that GLP treatment modulated glucose and cellular energy metabolisms by regulating relevant genes.GLP significantly suppressed the inflammations by impacting glucose and energy metabolism-related gene expression(Igfbp1 and Angptl4)and enhanced metabolic biomarkers of 4-Aminocatechol.In addition,NP analysis further indicated that GLP may efficiently alleviate DN via immune-related pathways.In conclusion,this study provides supportive evidence of the anti-inflammatory effects of GLP supplements,highlighting their potential for promising clinical applications in treating DN.

Traditional open head and neck surgery often leaves permanent scars,significantly affecting appearance.The emergence of surgical robots has introduced a new era for minimally invasive surgery.However,the complex anatomy of the head and neck region,particularly the oral and maxillofacial areas,combined with the high costs associated with established systems such as the da Vinci,has limited the widespread adoption of surgical robots in this field.Recently,surgical robotic platform in China has developed rapidly,exemplified by the promise shown by the KangDuo Surgical Robot(KD-SR).Although the KD-SR has achieved some results comparable to the da Vinci surgical robot in urology and colorectal surgery,its performance in complex head and neck regions remains untested.This study evaluated the feasibility,effectiveness,and safety of the newly developed KD-SR-01,comparing it with standard endoscopic systems in head and neck procedures on porcine models.We performed parotidectomy,submandibular gland resection,and neck dissection,collected baseline characteristics,perioperative data,and specifically assessed cognitive workload using the NASA-TLX.None of the robotic procedures were converted to endoscopic or open surgery.The results showed no significant difference in operation time between the two groups(P=0.126),better intraoperative bleeding control(P=0.001),and a significant reduction in cognitive workload(P<0.001)in the robotic group.In conclusion,the KD-SR-01 is feasible,effective,and safe for head and neck surgery.Further investigation through well-designed clinical trials with long-term follow-up is necessary to establish the full potential of this emerging robotic platform.

Objective:To evaluate the efficacy and impacts of air tamponadein treating rhegmatogenous retinal detachments (RRD) including inferior breaks after 25G pars plana vitrectomy (PPV).Methods:A prospective non-randomized study. From November 2016 to December 2018, 110 RRD patients receiving PPV in the Ophthalmology Department of Affiliated Hospital of Nantong University were included in the study. All the patients choose the operation mode voluntarily after fully understand the condition and operation mode. There were 90 eyes in the air filling group and 20 eyes in the silicone oil filling group. There was no difference of age ( t=-0.082), sex ratio ( χ2=1.538), left or right eye ( χ2=0.839), average course of disease ( Z=-0.276), intraocular pressure ( t=3.669), axial length ( t=0.765), grade of proliferative vitreous retinopathy ( Z=-2.101), high myopia ( χ2=0.013), lens state ( χ2=1.275), logMAR BCVA ( t=-0.681), the scope of retinal detachment ( t=0.970), the site ( χ2=0.108) and numbers ( t=0.158) of the retinal holes, whether involving macula ( χ2=1.791) between the two groups ( P>0.05). At 1, 3, and 6 months after surgery, the first retinal reduction rate, BCVA increase rate, visual recovery rate, intraocular pressure, fovea retinal thickness (CFT), ellipsoid and cross sectional area, and the occurrence of postoperative complications in the two groups were observed and compared. Independent sample t test and Chi-squared test, Mann-Whitney U test, and ANOVA were used for data comparision. Results:After the first operation, retinal reattachmnents were achieved in 87 eyes (96.6%) in the air group and 19 eyes (95.0%) in the silicone oil group ( χ2=0.130, P>0.05). In the air group and the silicone oil group, there were 7 and 2 eyes with subretinal holes, whose retinal reattachmnents were achieved. At 6 months after surgery, logMAR BCVA of the eyes in the air group and the silicone oil group were 0.23±0.23 and 0.37±0.23, respectively. All of them were higher than that before operation ( t=-2.410, P<0.001). BCVA in the air group was superior to that in the silicone oil group ( P<0.05). The increase rate of BCVA of the eyes in the air group and the silicone oil group were 0.69±0.28 and 0.48±0.30 logMAR units, respectively ( t=-3.225, P<0.05). The CFT of the eyes in the air group and the silicone oil group were 226.87±42.30 μm and 234.83±36.10 μm, respectively ( t=-0.448, P=0.657). In the air group and silicone oil group, posterior cataract was observed in 15 and 4 eyes, subretinal residual fluid in 1 and 2 eyes, and visual object deformation in 3 eyes respectively. In the air group and silicone oil group, posterior cataract was observed in 15 and 4 eyes, subretinal residual fluid in 1 and 2 eyes, and visual object deformation in 3 eyes respectively. Conclusions:Air filling combined with PPV can effectively treat RRD, which is suitable for both superior and inferior holes. The visual acuity recovered well and the complication is less. The time of retinal detachment (especially the time of macular detachment) is an important factor affecting the prognosis.
