OBJECTIVE: To investigate the effect and mechanism of Sanqi(Radix Notoginseng) in treating periodontitis. METHODS: The active components and periodontitis targets were analyzed through network pharmacology and molecular docking. A rat model of periodontitis was established and rats were treated by continuous intragastric administration of Sanqi(Radix Notoginseng) at different doses for 30 d. The alveolar bone structure was observed by micro-CT, the periodontal tissue structure was observed by hematoxylin-eosin staining, and the related proteins changes was detected by immunohistochemical staining. RESULTS: Sanqi(Radix Notoginseng) and periodontitis had a total of 96 coincident targets that were significantly enriched in the interleukin 17(IL-17), tumor necrosis factor(TNF), and advanced glycation endproducts and the receptor of advanced glycation endproducts signaling pathways. The active compound quercetin had good binding activity with interleukin 6(IL-6), vascular endothelial growth factor A(VEGFA), matrix metallopeptidase 9(MMP9), tumor necrosis factor α(TNF-α), Jun proto-oncogene(JUN), and C-X-C motif chemokine ligand 8(CXCL8) in periodontitis. Compared with normal group, the distance from the cementoenamel junction(CEJ) to the alveolar bone(AB) was increased, alveolar bone absorption was obvious, the periodontal tissue structure was disorganized, and IL-6 and TNF-α were upregulated in periodontitis group; meanwhile, the distance from CEJ to AB was significantly decreased, alveolar bone resorption was reduced, periodontal tissue structure was improved, the expression of IL-6, TNF-α, IL-17 and retinoid-ralated orphan receptor γt(RORγt) were decreased, Forkhead Box P3(FOXP3) and IL-10 were increased after Sanqi(Radix Notoginseng) treatment. CONCLUSIONS: Sanqi(Radix Notoginseng) improves the structure of alveolar bone and gum, and reduces inflammation; the mechanism involve in inhibiting IL-17 signaling pathway to suppress Th17 and promote Treg cells differentiati

Immunotherapy offers significant potential but is often hampered by the immunosuppressive environment in oral squamous cell carcinoma(OSCC).To address this,we propose an enhanced immunotherapeutic strategy that revitalizes the tumor immune microenvironment(TIME)in OSCC by integrating upconversion-based photodynamic therapy(PDT)with *** a red blood cell membraneinspired biomimetic nanoplatform,our approach concurrently delivers chlorin e6@upconversion nanoparticles(Ce6@UCNP)and doxorubicin(DOX).By leveraging fluorescence resonance energy transfer(FRET)for 980 nm to 660 nm upconversion excitation,we address challenges such as limited tissue penetration and tissue damage,as well as nanoplatform issues including immunogenicity and targeting inaccuracy Our integrated approach enhances PDT and chemotherapy with the goal of transforming immunologically“cold”tumors into“hot”ones through a cascaded therapy,thereby revitalizing the tumor immune microenvironment in OSCC.

Neuronal growth, extension, branching, and formation of neural networks are markedly influenced by the extracellular matrix—a complex network composed of proteins and carbohydrates secreted by cells. In addition to providing physical support for cells, the extracellular matrix also conveys critical mechanical stiffness cues. During the development of the nervous system, extracellular matrix stiffness plays a central role in guiding neuronal growth, particularly in the context of axonal extension, which is crucial for the formation of neural networks. In neural tissue engineering, manipulation of biomaterial stiffness is a promising strategy to provide a permissive environment for the repair and regeneration of injured nervous tissue. Recent research has fine-tuned synthetic biomaterials to fabricate scaffolds that closely replicate the stiffness profiles observed in the nervous system. In this review, we highlight the molecular mechanisms by which extracellular matrix stiffness regulates axonal growth and regeneration. We highlight the progress made in the development of stiffness-tunable biomaterials to emulate in vivo extracellular matrix environments, with an emphasis on their application in neural repair and regeneration, along with a discussion of the current limitations and future prospects. The exploration and optimization of the stiffness-tunable biomaterials has the potential to markedly advance the development of neural tissue engineering.

Diabetic wound healing is often complicated due to bacterial infections that intensify inflammation. Employing hydrogel dressings with inherent antibacterial properties can significantly reduce reliance on antibiotics for treating infected wounds in diabetics. Traditional hydrogels typically rely on the infiltration of bacteria into their porous structure to manifest antibacterial effects. However, this infiltration process is not only prolonged but can also exacerbate inflammation, further delaying the healing of the ***, promptly capturing and eliminating bacteria is crucial for enhancing the antibacterial efficiency of the hydrogel. In this context, we present a multifunctional hydrogel dressing, termed SIP, designed to tackle drug-resistant bacterial infections in diabetic wounds. This dressing integrates ionic liquid functional groups into a sericin-based matrix: phenylboronic acid for the immobilization of bacteria and imidazole for their subsequent annihilation. Expectedly, the SIP system demonstrates potent antibacterial activity against methicillin-resistant Staphylococcus aureus, verified through in vitro and in vivo experiments. As a result, SIP emerges as a promising candidate in the realm of hydrogel dressings with innate antibacterial properties, showcasing considerable potential for addressing diabetic wounds plagued by drug-resistant bacterial infections.

The extracellular vesicles show great potential as a noninvasive biomarker for the early detection of cancer. Hence, there is an urgent requirement to create biosensors that are time-saving, simple, and easily scalable in order to accomplish rapid, sensitive, and quantitative detection of extracellular vesicles. In this study, we present a self-propelled DNA walker powered by endonuclease *** CI, which enables the development of a “signal on” sensing platform for the rapid and highly sensitive detection of extracellular vesicles. The DNA motor employed tracks made of streptavidin magnetic beads, which consisted of substrate strands labeled with fluorescein and motor strands locked by aptamers. The aptamer recognition of the target protein on extracellular vesicles unlocked the motor strand, initiating the DNA motor process. After replacing the optimal buffer solution containing the endonuclease *** I, the motor strands autonomously moved along the streptavidin magnetic beads track, continuously releasing fluorescent molecules and producing detectable fluorescence signals. Under optimal conditions, the detection range was from 2×10～4particles/mL to 2×10～9particles/mL, with a detection limit of 2.9×10～3particles/mL,demonstrating excellent selectivity. This method has demonstrated good selectivity in different tumorderived extracellular vesicles and performs well in complex biological samples. The ability to effectively analyze surface proteins of extracellular vesicles in a short period of time gives our DNA walker a tremendous potential for developing simple and cost-effective clinical diagnostic devices.
