Objective To determine the effect of baicalein on high glucose-induced cardiac fibro-blast pyroptosis based on the nucleotide-binding oligomerization domain-like receptor protein 3(NLRP3)/cysteinyl aspartate-specific proteinase-1(Caspase-1)/gasdermin D(GSDMD)pathway.Methods Rat cardiac fibroblasts were grouped into control,high glucose group,low-,medium-and high-dose baicalein(H-,M-and L-baicalein)groups,and H-baicalein+NLRP3 agonist(BMS-986299)group.Except for the control group,all other groups were cultured in DMEM medium containing 40 mmol/L glucose,then 12.5,25 and 50 μmol/L baicalein was added into the medium correspondingly,and 1 μmol/L BMS-986299 was used to treat the H-baicalein+NLRP3 agonist group.Lactate dehydrogenase(LDH)cytotoxicity assay were employed to detect cell cytotoxicity.qRT-PCR and Western blotting were performed to determine the expression of NLRP3,Caspase-1,and GSDMD at mRNA and protein levels.Results High glucose treatment induced more EdU positive cells,higher pyroptotic rate,stronger cytotoxicity,higher Col-Ⅰ and Col-Ⅲ contents,and enhanced mRNA and protein levels of NLRP3,Caspase-1 and GSDMD in comparison to the control group(P＜0.05).The H-baicalein+NLRP3 agonist group had more EdU positive cells(26.85±2.95 cells vs 15.43±1.82 cells,P＜0.05),higher pyroptotic rate[(33.45±4.02)％vs(17.34±2.15)％,P＜0.05],stronger cytotoxicity[(27.94±2.93)％vs(14.13±1.87)％,P＜0.05],and increased contents of Col-Ⅰ(107.58±13.39 ng/ml vs 58.73±8.36 ng/ml,P＜0.05)and Col-Ⅲ(118.43±13.95 ng/ml vs 68.74±8.57 ng/ml,P＜0.05),and enhanced expression of NLRP3,Caspase-1 and GSDMD at both mRNA and protein levels(P＜0.05)when compared with the H-baicalein group.Conclusion Baicalein inhibits high glucose-induced cardiac fibroblast pyroptosis by suppressing NLRP3/Caspase-1/GSDMD pathway.

Atherosclerosis(As)is a chronic inflammatory vascular disease and serves as the pathological basis for various cardiovascular diseases.Epigallocatechin-3-O-gallate(EGCG)is the most abundant and biologically active com-pound in green tea,possessing multiple pharmacological effects such as anti-inflammatory,antiviral,and antioxidative stress properties.In recent years,studies have found that EGCG can regulate lipid metabolism,improve vascular endo-thelial function,and enhance plaque stability,demonstrating its potential value in combating As.This article provides a systematic review of the mechanisms underlying EGCG's anti-As effects,aiming to offer multi-faceted theoretical support for its further research and clinical application in the prevention and treatment of As.

Objective:To systematically evaluate and integrate qualitative research from nurses on perceptions and feelings of elder self-neglect, with the aim of providing a reference for early identification, prevention, and intervention of elder self-neglect by nursing staff.Methods:Qualitative research of nurses' perceptions and feelings of elder self-neglect was systematically searched in the Cochrane Library, PubMed, Embase, Web of Science, China National Knowledge Infrastructure, WanFang Data, VIP, and China Biology Medicine disc by computer. The search period was from database establishment to March 31, 2024. The quality of the literature was evaluated according to the quality evaluation criteria for qualitative research of the Australia Joanna Briggs Institute Evidence-Based Health Care Center. The aggregate integration approach was used to integrate the findings of the study.Results:A total of eight papers were included to distill 30 findings, and similar findings were generalized and integrated to form 11 categories and synthesized into three integrated findings, including nurses' perception of elder self-neglect, manifestations of elder self-neglect from nurses' perspectives, and influencing factors of elder self-neglect from nurses' perspectives.Conclusions:Nurses should understand the manifestations and influencing factors of elder self-neglect, improve own professionalism, and help the elderly establish positive coping mechanisms to promote healthy aging.

Objective: To evaluate the clinical efficacy of digitally guided precision crown lengthening in secondary aesthetic rehabilitation cases, and to provide a clinical reference for digitally guided crown lengthening procedures and secondary aesthetic restorations. Methods: We present a case of a patient with tetracycline-stained teeth, partial detachment of anterior resin veneers, and gingival margin discrepancies. The patient underwent digitally guided precision crown lengthening followed by secondary aesthetic rehabilitation. Multimodal data, including intraoral, facial, and CBCT scans, were integrated to construct a four-dimensional virtual patient model (incorporating teeth, face, bone, and occlusion) for surgical planning and 3D-printed guide fabrication. Secondary aesthetic restoration was performed after achieving stable post-surgical outcomes. Based on this case, we conducted a detailed analysis and reviewed relevant literature on crown lengthening in secondary aesthetic rehabilitation. Results: The gingival contour of the anterior teeth exhibited significant improvement, with enhanced symmetry and stable gingival margin positioning that closely matched the preoperative design. The crown lengthening procedure demonstrated high precision, and the final outcome was aesthetic and functional. Literature review indicated that secondary restorations frequently present challenges such as gingival contour discrepancies and inflammation. Aesthetic crown lengthening in the anterior region should optimize both soft and hard tissue morphology to meet aesthetic standards, with digital technology improving procedural accuracy. Conclusion Precision crown lengthening effectively addresses gingival margin discrepancies in secondary aesthetic rehabilitation, ensuring stable gingival positioning and superior aesthetic outcomes. This approach is particularly suitable for cases with high aesthetic demands.

Objective:To explore the risk factors of delayed extubation after expanded thymectomy in patients with myasthenia gravis.Methods:Patients with myasthenia gravis who underwent expanded thymectomy from May 2021 to January 2024 and were admitted to Intensive Care Unit (ICU) after surgery were retrospectively analyzed. Patients were divided in to the delayed extubation and successful extubation according to the length of mechanical ventilation whether exceeding than 48 hours. Multivariable logistics regression was used to explore the risk factors for delayed extubation after expanded thymectomy in patients with myasthenia gravis.Results:A total of 95 patients were included.15 (15.8%) of whom were delayed extubation. Compared with the successful extubation patients, the length of mechanical ventilation (94.0 h vs. 15.5 h, P<0.001), ICU station (7.1 days vs. 1.7 days, P<0.001), and hospitalization station (16.0 days vs. 9.1 days, P<0.001) were significantly prolonged in the delayed extubation patients. Adjusted for age,gender, BMI, clinical classification, pathological classification of thymoma, dose of pyridostigmine preoperative, perioperative pneumonia, preoperative pulmonary dysfunction, SBT passing for the first time, neck lift time greater than 20 seconds, the multivariable logistic regression shown, the risk of delayed extubation increased by 29% ( OR=1.290, 95% CI 1.090-1.714), 1% ( OR=1.009, 95% CI 1.002-1.034), 3.9-fold ( OR=4.977, 95% CI 1.486-10.939), and 64% ( OR=1.635, 95% CI 1.396-2.682) for every 60 mg/day increase in preoperative dose of pyridostigmine, pathological classification of thymoma, perioperative pneumonia, and preoperative pulmonary dysfunction, respectively. Neck lift time greater than 20 seconds can reduce the risk of delayed extubation 48% ( OR=0.524, 95% CI 0.322-0.794). Conclusion:Preoperative administration of a large dose of pyridostigmine, pulmonary dysfunction, pathological classification of thymoma, and perioperative pneumonia were risk factors for delayed extubation after thymectomy in these patients. And neck lift time greater than 20 seconds decreased the risk of delayed extubation. In the clinical practice,for high risk of MG patients with delayed extubation, the neck lifting test may be used to assess muscle strength and reduce the occurance of tracheal reintubation and its advise effects.
