Objective: This study aims to evaluate the clinical benefits of the integrated optical and magnetic surgical navigation system in assisting transforaminal endoscopic lumbar discectomy (TELD) for the treatment of lumbar disc herniation (LDH). Methods: A retrospective analysis was conducted on patients who underwent TELD for LDH at Beijing Chaoyang Hospital, Capital Medical University from November 2022 to December 2023. Patients treated with the integrated optical and magnetic surgical navigation system were defined as the navigation-guided TELD (Ng-TELD) group (30 cases), while those treated with the conventional x-ray fluoroscopy method were defined as the control group (31 cases). Record and compare baseline characteristics, surgical parameters, efficacy indicators, and adverse events between the 2 patient groups. Results: The average follow-up duration for the 61 patients was 11.8 months. Postoperatively, both groups exhibited significant relief from back and leg pain, which continued to improve over time. At the final follow-up, patients’ lumbar function and quality of life had significantly improved compared to preoperative levels (p < 0.05). The Ng-TELD group had significantly shorter total operation time (58.43 ± 12.37 minutes vs. 83.23 ± 25.90 minutes), catheter placement time (5.83 ± 1.09 minutes vs. 15.94 ± 3.00 minutes), decompression time (47.17 ± 11.98 minutes vs. 67.29 ± 24.23 minutes), and fewer intraoperative fluoroscopies (3.20 ± 1.45 vs. 16.58 ± 4.25) compared to the control group (p < 0.05). There were no significant differences between the groups in terms of efficacy evaluation indicators and hospital stay. At the final follow-up, the excellent and good rate of surgical outcomes assessed by the MacNab criteria was 98.4%, and the overall adverse event rate was 8.2%, with no statistically significant differences between the groups (p > 0.05). Conclusion This study demonstrates that the integrated optical and magnetic surgical navigation system can reduce the complexity of TELD, shorten operation time, and minimize radiation exposure for the surgeon, highlighting its promising clinical potential.

AIM To prepare curcumin-loaded poly (D,L-lactide-co-glycolide) acid (PLGA) nanoparticles,and to investigate their effects on promoting wound healing.METHODS Phacoemulsification method was adopted in the preparation of PLGA nanoparticles.With lactic acid-glycolic acid ratio,surfactant type and concentration and PLGA consumption as influencing factors,encapsulation efficiency,drug loading,particle size and PDI as evaluation indices,the preparation process was optimized by single factor test.The morphology was observed under transmission electron microscopy,after which the in vitro drug release was determined by dialysis bag method,the optical properties were investigated by fluorescence spectroscopy,and the effects on promoting wound healing of mouse skin.RESULTS The optimal conditions were determined to be 50∶50 for lactic acid-glycolic acid ratio,60 mg for PLGA consumption,and 3％ for surfactant (PVA) concentration.The obtained PLGA nanoparticles with spherical core-shell structure demonstrated the average particle size,PDI,Zeta potential and accumulative release rate within 168 h of (149.70±7.27) nm,0.28±0.04 and (-10.18±1.00) mV and (39.21±1.44)％,respectively,which displayed typical aggregation-induced emission property,excitation wavelength-dependent property and optical stability.Compared with the PBS group,PBS+illumination group,curcumin+illumination group and preparation group,the preparation+illumination group exhibited increased wound healing rate (P<0.05,P<0.01) and reduced wound epidermal thickness (P<0.05,P<0.01).CONCLUSION Curcumin-loaded PLGA nanoparticles show good optical properties,which can promote the wound healing of mouse skin when combined with photodynamic therapy.

AIM To investigate the effects of aloperine on the pulmonary expressions of TREM-1 and TREM-2 in septic rats.METHODS The rats were randomly divided into the control group,the model group and the low,medium and high dose aloperine groups ( 25,50 and 100 mg/kg ).The corresponding intraperitoneal aloperine injection was administered 0.5 h before modeling,and the rats'Penh,Cdyn and EF50 were detected 24 hrs after modeling.The rats had their pathological injury of the lung tissue observed by HE staining;their pulmonary mRNA expressions of TREM-1,TREM-2,TNF-α,IL-1β and IL-10 detected by RT-qPCR method;and their pulmonary protein expressions of TREM-1,TREM-2,TNF-α,IL-1β,IL-10,p-p65,p-PI3K and p-Akt detected by Western blot.RESULTS Compared with the control group,the model group displayed increased Penh (P<0.01),decreased Cdyn and EF50 ( P<0.01);destroyed lung tissue structure and thickened alveolar septum,increased mRNA and protein expressions of TREM-1,TNF-αand IL-1β( P<0.05,P<0.01);decreased mRNA and protein expressions of TREM-2 and IL-10 ( P<0.05,P<0.01);and increased protein expressions of p-p65,p-PI3K and p-Akt (P<0.01).Compared with the model group,the aloperine groups shared decreased Penh ( P<0.01);increased Cdyn and EF50 ( P<0.01);improved pulmonary structure and thinner alveolar wall,decreased mRNA and protein expressions of TREM-1,TNF-α and IL-1β( P<0.05,P<0.01 );increased mRNA and protein expressions of TREM-2 and IL-10 ( P<0.05,P<0.01);and decreased protein expressions of p-p65,p-PI3K and p-Akt (P<0.05,P<0.01).CONCLUSION Aloperine can alleviate the inflammatory response of septic rats by down-regulating TREM-1 expression and up-regulating TREM-2 expression,which may be related to the inhibited activation of PI3K signaling pathway.

Objective To explore the safety and efficacy of radiofrequency catheter ablation(RCFA)in patients with persistent atrial fibrillation(AF)/atrial flutter(AFL)and heart failure(HF)with left ventricular ejection fraction≤35％.Methods This study is a retrospective study.Patients with persistent AF/AFL and HF with left ventricular ejection fraction≤ 35％admitted to Beijing Anzhen Hospital from January 2018 to March 2024 were enrolled.The perioperative characteristics and complications changes in echocardiographic parameters,and follow-up outcomes were analyzed.Results A total of 45 patients were enrolled with a mean age of(56±13)years and a mean LVEF of(28±4)％.The ablation strategy was circumferential pulmonary vein isolation and empirical linear ablation.The operation time and fluoroscopy time were 120(120,163)min and 5(4,10)min respectively.The patients mainly underwent linear ablation including circumferential pulmonary vein isolation(38,84.4％),cavotricuspid isthmus(37,82.2％),roofline(34,75.6％),mitral isthmus(34,75.6％).21(46.7％)patients underwent ehtanol infusion into the vein of Marshall.24(53.3％)patients underwent electrocardioversion.All patients restored sinus rhythm immediately after RFCA and had no perioperative complications.After a median follow-up of 22.9(7.8,31.0)months,2 patients died of cardiovascular disease,1 patient underwent heart transplantation,14(33.3％)patients were readmitted for cardiovascular disease,and 10 patients(23.8％)had recurrence of AF.The mean LVEF of the 28 patients who obtained LVEF at the last follow-up increased from(28±4)％to(51±14)％,and the average improvement of LVEF was(23±13)％(P＜0.0001).15 of these patients had complete recovery of left ventricular systolic function(LVEF≥ 50％).Conclusions RFCA is safe and effective for patients with persistent AF/AFL and HF with LVEF ≤ 35％,and can improve patient's cardiac function and significantly increase LVEF.
