Idiopathic pulmonary fibrosis (IPF) is a chronic interstitial lung disease characterized by dyspnea and progressive deterioration of lung function, which significantly impacts patients' quality of life and imposes a major burden on society. Although modern medicine has increasingly enriched the treatment options for pulmonary fibrosis, unfavorable factors such as high costs and significant side effects contribute to the persistently low survival rate of patients. Studies have shown that the occurrence and development of pulmonary fibrosis are closely related to abnormalities in multiple pathways. Among these, Rho/Rho-associated coiled-coil protein kinase (ROCK) plays a key role in the disease progression of IPF by regulating the cytoskeleton. This pathway not only transmits biochemical molecular signals that promote the progress of fibrosis but also responds to the biomechanical environment, such as the increased lung tissue stiffness caused by the deposition of extracellular matrix (ECM) during the process of pulmonary fibrosis. Therefore, research on this pathway is of great significance for the prevention and treatment of IPF. In recent years, traditional Chinese medicine (TCM) has shown remarkable effects in preventing and treating IPF. Many TCM compounds and active components can reduce the production of α-smooth muscle actin (α-SMA), CollagenⅠ (ColⅠ), ColⅢ, and inflammatory factors in lung tissue by regulating the Rho/ROCK signaling pathway. These compounds inhibit the transformation of fibroblasts (FBs) into myofibroblasts (MyoFBs), intervening in the process of pulmonary fibrosis. Based on this, the article briefly reviews relevant research from recent years, discusses the key role of the Rho/ROCK pathway in pulmonary fibrosis from an interdisciplinary perspective, and summarizes the mechanisms through which TCM regulates Rho/ROCK to prevent and treat IPF, based on resources from PubMed, CNKI, and other databases, in order to provide important references for the broader clinical application of TCM in the prevention and treatment of IPF.

Objective To compare the differences in stress on maxillary anterior implants and labial cortical bone under varying thicknesses of palatal bone plates through three-dimensional finite element analysis.Methods Using CBCT scan data and finite ele-ment software,a three-dimensional finite element model of maxillary central incisor implant restoration was constructed.The thickness of the palatal bone plate at the cervical region of the implant was set to 0,0.5,1.0 mm,respectively.The effects of different palatal bone plate thicknesses on the equivalent stress of the implant and the minimum principal stress(compressive stress)of the labial corti-cal bone under normal occlusal conditions were simulated.Results Under normal occlusion,when the palatal cervical bone plate thickness was 0,0.5,1.0 mm,the maximum equivalent stress of the implant was consistently located at the midline of the labial cervi-cal region at the implant-abutment interface,with values of 106.8,103.5,99.71 MPa,respectively.Meanwhile,the minimum princi-pal stress of the cortical bone appeared at the alveolar crest at the junction of the implant-abutment and labial alveolar bone,measuring 107.8,103.2,95.55 MPa,respectively.The results indicated that as the palatal cervical bone plate thickness decreased,both the maximum equivalent stress of the implant and the minimum principal stress of the labial cortical bone exhibited an increasing trend,though they remained below their respective yield strengths.Conclusion From a biomechanical perspective,maxillary anterior implant restoration remains feasible even when the thickness of the palatal bone plate at the cervical region of the implant is 0 mm.

Objective To explore the roles of transcription factor E26 transformation-specific 1(ETS1)and F-box protein 45(FBXO45)in invasion and metastasis in hepatocellular carcinoma cells and the potential molecular mechanism.Methods Jaspar,hTFtarget and Cistrome transcription factor database prediction websites were used to predict the transcription factors of FBXO45.According to the intersection of the predicted results of each database,the expression of FBXO45 was detected after the candidate transcription factors were knockdown in HCCLM3 and Huh7 liver cancer cells,respectively.The most significant influence on FBXO45 expression was selected for further analysis,and chromatin immunoprecipitation assay(ChIP)was used to verify the binding to the FBXO45 promoter.Finally,the potential transcription factor of FBXO45 was identified.The effect of ETS1 overexpression on invasion and migration in HCCLM3 and Huh7 cells was detected by Transwell assay,and the expression levels of epithelial-mesenchymal transition(EMT)pathway proteins were detected by Western blot assay.The effects of FBXO45 knockdown on the invasion and migration under the condition of overexpression of ETS1 were also studied.Results Intersection of FBXO45 transcription factors identified 3 candidate transcription factors,ETS1,SPI1 and YY1.When the 3 transcription factors were knocked down in HCCLM3 and Huh7 cells,respectively,ETS1 knockdown significantly reduced the expression of FBXO45.According to the analysis of The Cancer Genome Atlas(TCGA)data and the Gene Expression Omnibus(GEO)data,the expression levels of ETS1 and FBXO45 were significantly positively correlated(R=0.31,P<0.000 1;R=0.40,P=0.021 9).ChIP suggested that ETS1 could specifically bind to FBXO45 promoter sequence to regulate its expression,confirming that ETS1 was a potential transcription factor of FBXO45.After overexpression of ETS1 in HCCLM3 and Huh7 cells,the invasion and migration abilities of cells were significantly enhanced,and the expression of N-cadherin and Snail was up-regulated(P<0.01).In addition,in the case of ETS1 overexpression,FBXO45 knockdown significantly inhibited the invasion and migration(P<0.01).Conclusion ETS1 activates the transcription of FBXO45 and leads its high expression,which enhances the invasion and migration of HCC cells via EMT pathway and promotes the progression of hepatocellular carcinoma.

Cancer represents a major worldwide disease burden marked by escalating incidence and mortality. While therapeutic advances persist, developing safer and precisely targeted modalities remains imperative. Nanomedicines emerges as a transformative paradigm leveraging distinctive physicochemical properties to achieve tumor-specific drug delivery, controlled release, and tumor microenvironment modulation. By synergizing passive enhanced permeation and retention effect-driven accumulation and active ligand-mediated targeting, nanoplatforms enhance pharmacokinetics, promote tumor microenvironment enrichment, and improve cellular internalization while mitigating systemic toxicity. Despite revolutionizing cancer therapy through enhanced treatment efficacy and reduced adverse effects, translational challenges persist in manufacturing scalability, longterm biosafety, and cost-efficiency. This review systematically analyzes cutting-edge nanoplatforms, including polymeric, lipidic, biomimetic, albumin-based, peptide engineered, DNA origami, and inorganic nanocarriers, while evaluating their strategic advantages and technical limitations across three therapeutic domains: immunotherapy, chemotherapy, and radiotherapy. By assessing structure-function correlations and clinical translation barriers, this work establishes mechanistic and translational references to advance oncological nanomedicine development.
