IL-33 and its receptor ST2 play crucial roles in tissue repair and homeostasis. However, their involvement in optic neuropathy due to trauma and glaucoma remains unclear. Here, we report that IL-33 and ST2 were highly expressed in the mouse optic nerve and retina. Deletion of IL-33 or ST2 exacerbated retinal ganglion cell (RGC) loss, retinal thinning, and nerve fiber degeneration following optic nerve (ON) injury. This heightened retinal neurodegeneration correlated with increased neurotoxic astrocytes in Il33-/- mice. In vitro, rIL-33 mitigated the neurotoxic astrocyte phenotype and reduced the expression of pro-inflammatory factors, thereby alleviating the RGC death induced by neurotoxic astrocyte-conditioned medium in retinal explants. Exogenous IL-33 treatment improved RGC survival in Il33-/- and WT mice after ON injury, but not in ST2-/- mice. Our findings highlight the role of the IL-33/ST2 axis in modulating reactive astrocyte function and providing neuroprotection for RGCs following ON injury.

In the context of medical insurance payment reform,the sample hospital has implemented performance management optimization to effectively address the challenges posed by diagnosis-intervention packet(DIP)payment.Reform measures focused on disease quality,rational diagnosis and treatment,operational management,medical technological value,and policy orientation,and they have significantly optimized service ability and performance evaluation indexes of the hospital.Main achievements included a reduction in the cost consumption index and an increase in the clinical performance index,with the overall DIP payment rate increasing from 88.86%to 103.23%and a marked improvement in operational management.The quality control and operational efficiency of the hospital have been effectively enhanced by choosing proper DIP payment evaluation indexes and improving performance management,and provided strong support for the high-quality development of the hospital.

Probiotics have shown excellent application prospects in preventing and treating many diseases. However, their sensitivity to the harsh environment in vivo always leads to a massive loss of viability and insufficient therapeutic effect. Fortunately, modified probiotics have emerged and provide multiple possibilities for their use in various diseases. Modification not only endows probiotics with extra capacity to resist severe environments but also gives them exogenous characteristics, such as prolonged retention time and improved therapeutic effects. Modified probiotics could combine with other therapies, which has opened up new avenues to enhance the efficacy of probiotic-based therapy. In this review, we have summarized the current physicochemical and biological modification strategies of probiotics. In addition, the progress of research on probiotic-based combination therapy has also been extensively reviewed, which contributes to the enhanced delivery of probiotics or other active constituents and provides new ideas for disease treatment, bioimaging, and diagnosis.

OBJECTIVES:
To evaluate the early clinical efficacy and safety of trans-catheter aortic valve replacement (TAVR) for patients with severe pure native aortic regurgitation (PNAR) who are not suitable for conventional surgical aortic valve replace-ment.
METHODS:
A retrospective analysis was conducted on 48 patients with PNAR who underwent TAVR at the Department of Cardiac Surgery, the First Affiliated Hospital of Sun Yat-sen University between March 2019 and February 2025. These included 25 cases with transfemoral approach (TF-TAVR group) and 23 cases with transapical approach (TA-TAVR group). Efficacy and safety were assessed by analyzing baseline characteristics, all-cause mortality, and procedure-related complications.
RESULTS:
Compared with the TA-TAVR group, the TF-TAVR group exhibited significantly smaller aortic annulus circumference and diameter, left ventricular outflow tract circumference and diameter, diameters of the left, right, and non-coronary sinuses, and sinotubular junction (STJ) diameter, along with a shorter distance from the STJ to the aortic annular plane ring plane, a smaller annulus angle (all P<0.05). Additionally, the TF-TAVR group showed a deeper prosthesis implantation depth relative to the aortic annular plane (P<0.01). The overall technical success rate was 91.67%, and the device success rate was 83.33%. Post-TAVR, both groups demonstrated significant improvement in left ventricular end-diastolic diameter (both P<0.05), while only the TA-TAVR group showed significant reduction in left ventricular end-systolic diameter (P<0.05). For primary outcomes, in-hospital mortality occurred in 2 patients (4.17%). No additional deaths were reported at 60 or 90 d after surgery. During 90-180 d after surgery, one patient in the TF-TAVR group died of sudden cardiac death, and one in the TA-TAVR group died of gastroin-testinal bleeding. During 180 d-1 year after surgery, one patient in the TF-TAVR group died of low cardiac output syndrome. No statistically significant differences were observed in 1-year Kaplan-Meier survival curves between the two groups (P>0.05). No conduction block events occurred in TA-TAVR group during hospitalization or 1-year follow-up, while high-grade atrioventricular block, left bundle branch block, permanent pacemaker implantation occurred in TF-TAVR group during hospitalization (12.00%, 4.00%, and 12.00%, respectively).
CONCLUSIONS
TAVR demonstrates high feasibility and acceptable safety for severe PNAR patients who are not suitable for conventional SAVR. Both TF-TAVR and TA-TAVR show comparable early postoperative efficacy and safety profiles.
