ObjectiveTo investigate the intervention effects and mechanisms of the flavonoid hyperoside (Hyp) on lipopolysaccharide (LPS)-induced inflammation in the zebrafish model. MethodsZebrafish larvae were either microinjected with 0.5 g·L-1 LPS or immersed in 1 g·L-1 LPS for the modeling of inflammation. The larvae were then treated with Hyp at 25, 50, and 100 mg·L-1 through immersion for four consecutive days. The inflammatory phenotypes were assessed by analyzing the mortality rate, malformation rate, body length, and yolk sac area ratio. Behavioral tests were conducted to evaluate the inflammatory stress responses, and macrophage migration was observed by fluorescence microscopy. Additionally, the mRNA levels of inflammation-related genes, including interleukin-1β (IL-1β), interleukin-6 (IL-6), chemokine C-C motif ligand 2 (CCL2), chemokine C-X3-C motif receptor 1 (CX3CR1), chemokine C-C motif receptor 2 (CCR2), and genes associated with the Toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88)/nuclear factor-kappa B (NF-κB) signaling pathway, were measured by Real-time quantitative polymerase chain reaction(Real-time PCR). ResultsCompared with the pure water injection group, the model group exhibited increased mortality, malformation rates and yolk sac area ratio (P0.01), reduced body length (P0.01), increased total swimming distance and high-speed swimming duration (P0.01), and up-regulated mRNA levels of TLR4, MyD88, NF-κB, IL-1β, IL-6, CCL2, CX3CR1, and CCR2 (P0.01). Hyp at low, medium and high doses, as well as aspirin, reduced the mortality and malformation rates (P0.05,P0.01), increased the body length (P0.05,P0.01), decreased the yolk sac area ratio (P0.01), reduced the high-speed swimming duration (P0.01), and down-regulated the mRNA levels of TLR4, MyD88, NF-κB, IL-1β, IL-6, CCL2, CX3CR1, and CCR2 (P0.05,P0.01) compared with the model group. ConclusionHyp may modulate the TLR4/MyD88/NF-κB pathway to ameliorate inflammatory phenotypes and alleviate stress conditions in zebrafish, thereby exerting the anti-inflammatory effect.

Hip fracture in the elderly is characterized by high incidence, high disability rate, and high mortality and has been recognized as a public health issue threatening their health. Surgery is the preferred choice for the treatment of elderly patients with hip fracture. However, lower extremity deep venous thrombosis (DVT) has an extremely high incidence rate during the perioperative period, and may significantly increase the risk of patients′ death once it progresses to pulmonary embolism. In response to this issue, the clinical guidelines and expert consensuses all emphasize active application of comprehensive preventive measures, including basic prevention, physical prevention, and pharmacological prevention. In this prevention system, basic prevention is the basis of physical and pharmacological prevention. However,there is a lack of unified and definite recommendations for basic preventive measures in clinical practice. To this end, the Orthopedic Nursing Professional Committee of the Chinese Nursing Association and Nursing Department of the Orthopedic Branch of the China International Exchange and Promotive Association for Medical and Health Care organized relevant nursing experts to formulate Expert consensus on perioperative basic prevention for lower extremity deep venous thrombosis in elderly patients with hip fracture ( version 2024) . A total of 10 recommendations were proposed, aiming to standardize the basic preventive measures for lower extremity DVT in elderly patients with hip fractures during the perioperative period and promote their subsequent rehabilitation.

BACKGROUND:Growth differentiation factor 5 is a member of the transforming growth factor superfamily and one of the earliest markers of joint development.Growth differentiation factor 5 has an important role in cartilage repair. OBJECTIVE:To explore the action mechanism of growth differentiation factor 5-induced chondrogenic differentiation of bone marrow mesenchymal stem cells. METHODS:Rabbit bone marrow mesenchymal stem cells were isolated and cultured.CCK-8 assay was used to detect the effect of different mass concentrations of growth differentiation factor 5 on the proliferation activity of bone marrow mesenchymal stem cells.RT-PCR was utilized to detect the expression of genes related to chondrogenic differentiation of bone marrow mesenchymal stem cells induced by different mass concentrations of growth differentiation factor 5.To further investigate the action mechanism of growth differentiation factor 5-induced chondrogenic differentiation of bone marrow mesenchymal stem cells,we added inhibitor XAV-939 and activator Laduviglusib of Wnt/β-catenin signaling pathways to induce cell culture for 14 days.RT-PCR and western blot assay were performed to detect the expression of cartilage-related genes and Wnt/β-catenin signaling pathway proteins. RESULTS AND CONCLUSION:(1)CCK-8 results showed no significant effect of growth differentiation factor 5 on the proliferation of bone marrow mesenchymal stem cells.(2)Growth differentiation factor 5 promoted the expression of cartilage-related genes type Ⅱ collagen,aggrecan and Sox9,among which growth differentiation factor 5 induced a significant upregulation of cartilage-related genes in the 50 ng/mL group.(3)Addition of Laduviglusib,an activator of Wnt/β-catenin signaling pathway,upregulated Sox9,β-catenin and type Ⅱ collagen expression(P<0.05).Addition of XAV939,an inhibitor of Wnt/β-catenin signaling pathway,down-regulated Sox9,β-catenin and type Ⅱ collagen expression(P<0.05).(4)Taken together,growth differentiation factor 5-induced chondrogenic differentiation of bone marrow mesenchymal stem cells may be associated with the activation of the Wnt/β-catenin signaling pathway.
