Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.

Saponins associated with Panax notoginseng (P. notoginseng) demonstrate significant therapeutic efficacy across multiple diseases. However, certain high-yield saponins face limited clinical applications due to their reduced pharmacological efficacy. This study synthesized and evaluated 36 saponin-1,2,3-triazole derivatives of ginsenosides Rg1/Rb1 and notoginsenoside R1 for anti-adipogenesis activity in vitro. The research revealed that the ginsenosides Rg1-1,2,3-triazole derivative a17 demonstrates superior adipogenesis inhibitory effects. Structure-activity relationships (SARs) analysis indicates that incorporating an amidyl-substituted 1,2,3-triazole into the saponin side chain via Click reaction enhances anti-adipogenesis activity. Additionally, several other derivatives exhibit general adipogenesis inhibition. Compound a17 demonstrated enhanced potency compared to the parent ginsenoside Rg1. Mechanistic investigations revealed that a17 exhibits dose-dependent inhibition of adipogenesis in vitro, accompanied by decreased expression of preadipocytes. Peroxisome proliferator-activated receptor γ (PPARγ), fatty acid synthase (FAS), and fatty acid binding protein 4 (FABP4) adipogenesis regulators. These findings establish the ginsenoside Rg1-1,2,3-triazole derivative a17 as a promising adipocyte differentiation inhibitor and potential therapeutic agent for obesity and associated metabolic disorders. This research provides a foundation for developing effective therapeutic approaches for various metabolic syndromes.

Objective: To explore the facilitating and hindering factors of mental health promotion activities in junior and senior high schools from teachers perspectives, as well as coping strategies, so as to provide evidence for implementing teacher led mental health promotion programs. Methods: From September 2023 to September 2024, by using purposive sampling method, 5 junior high schools, 5 regular high schools, 2 vocational high schools in four provinces and municipalities (Tianjin, Shanxi, Shandong, and Jiangxi) were selected. A total of 92 teachers (78 homeroom teachers and 14 full time or part time psychological counselors) were interviewed using semi structured focus group discussions (one session per school, totaling 12 sessions). Thematic analysis was applied to code and analyze the interview transcripts. Results: The implementation of mental health promotion activities in middle schools was influenced by three levels: teachers, schools and society. Specifically, teachers exhibited a high support low capability phenomenon (81 participants supported conducting such activities, but 71 felt lacking in professional capacity); activity effectiveness and support systems were imbalanced (42 mentioned significant effects, while 78 reported insufficient support); there was a mismatch between student demand and activity content (9 mentioned students had psychological needs, but 11 indicated existing activities failed to meet these needs); administrative support and sustainability showed disparities (14 believed sufficient administrative support existed, while 37 noted sustainability issues); parental awareness and participation remained inadequate (11 highlighted parents need for mental health knowledge, and 37 perceived insufficient understanding of psychological issues among parents). Effective strategies included enhancing teachers effectiveness, providing essential skill training, focusing on the needs of teenagers,enhancing program sustainability, and eliminating misconceptions about mental health among parents. Conclusion Mental health promotion activities in junior and senior high schools should focus on enhancing teachers skills, improving activity sustainability, reducing stigma among parents, and establishing a collaborative network for school based mental health promotion.

ObjectiveTo investigate the role of the Wnt1/β-catenin signaling pathway in the intervention of medicated serum of Buyang Huanwutang （BYHWT） in endothelial-to-mesenchymal transition （EndMT） of human pulmonary artery endothelial cells （HPAECs） as well as its related mechanisms. MethodMedicated serum of BYHWT was prepared by gavage to New Zealand rabbits with a dosage of 53.36 g·kg^-1·d^-1 after decocting the medicine as usual. In addition， the same volume of normal saline was used to prepare blank serum. The HPAECs were cultured in vitro， and then induced by the transforming growth factor-β₁ （TGF-β₁） to establish the EndMT model. Five groups were established： blank group （10% blank serum）， model group （TGF-β₁+10% blank serum）， low-dose BYHWT group （TGF-β₁+2.5% medicated serum+7.5% blank serum）， medium-dose BYHWT group （TGF-β₁+5% medicated serum+5% blank serum） and high-dose BYHWT group （TGF-β₁+10% medicated serum）. Through Western blot， the expressions of Wnt1， β-catenin， and glycogen synthase kinase-3β （GSK-3β） were detected. In order to further clarify the mechanism of the Wnt1/β-catenin signaling pathway in the intervention of the medicated serum of BYHWT in inhibiting EndMT， the overexpression of β-catenin was confirmed by polymerase chain reaction after plasmid of overexpression β-catenin was constructed and transfected into the HPAECs. The HPAECs were intervened by 10% medicated serum with the optimal effect in previous studies. Then， they were divided into another five groups： the blank group （10% blank serum）， the model group （TGF-β₁+10% blank serum）， the BYHWT group （TGF-β₁+10% medicated serum）， the BYHWT+overexpression plasmid control group （TGF-β₁+10% medicated serum+blank plasmid） and the BYHWT+β-catenin overexpression plasmid group （TGF-β₁+10% medicated serum+β-catenin）. Apart from that， cell proliferation ability was detected by the methyl thiazolyl tetrazolium （MTT） method and cell migration ability by scratch assay and Transwell assay together. Immunofluorescence was adopted to detect the expressions of platelet endothelial cell adhesion molecule （PECAM-1/CD31）， vascular endothelial cadherin （VE-cadherin）， fibroblast-specific protein 1 （FSP1）， and α-smooth muscle actin （α-SMA）. ResultIn comparison to the blank group， the expressions of Wnt1 and β-catenin were significantly increased （P<0.01） while the expression of GSK-3β significantly decreased （P<0.01） in the model group. In comparison to the model group， the expressions of Wnt1 and β-catenin were significantly decreased （P<0.01） while the expression of GSK-3β was significantly increased （P<0.01） in the high-dose BYHWT group. The expression of β-catenin was significantly decreased （P<0.01） while the expression of GSK-3β was significantly increased （P<0.01） in the medium-dose BYHWT group. There was no significant difference in these indexes of the low-dose BYHWT group. In comparison to the blank group， proliferation and migration abilities were remarkably increased （P<0.01） and the immunofluorescence intensities of CD31 and VE-cadherin were decreased， while those of FSP1 and α-SMA were increased in the model group. In comparison to the model group， proliferation and migration abilities were significantly decreased （P<0.01） and the immunofluorescence intensities of CD31 and VE-cadherin were increased， while those of FSP1 and α-SMA diminished in the BYHWT group. Beyond that， the change trend of those indexes in the BYHWT+β-catenin overexpression plasmid group was consistent with that in the model group. In comparison to the BYHWT+overexpression plasmid control group， proliferation and migration abilities were significantly increased （P<0.01） and the immunofluorescence intensities of CD31 and VE-cadherin were decreased， while those of FSP1 and α-SMA were increased in the BYHWT+β-catenin overexpression plasmid group. ConclusionMedicated serum of BYHWT can inhibit EndMT of HPAECs by the Wnt1/β-catenin signaling pathway.
