OBJECTIVE To investigate the effects of jaceosidin on osteoarthritis (OA) of rats by regulating adenosine monophosphate-activated protein kinase (AMPK)/NOD-like receptor protein 3 (NLRP3) pathway. METHODS Rats were randomly separated into OA group, jaceosidin group (33.33 mg/kg), AMPK inhibitor (Compound C, 20 mg/kg) group, jaceosidin (33.33 mg/kg)+Compound C (20 mg/kg) group, and sham operation group, with 12 rats in each group. Except for the sham operation group, the OA model was induced with modified Hulth method in all other groups. After successful modeling, they were given a relevant dose of jaceosidin or normal saline intragastrically, and Compound C or normal saline intraperitoneally, once a day, for consecutive 8 weeks. Twenty-four h after the last medication, the degree of knee joint swelling in rats from each group was measured. The pathological changes of the articular cartilage tissue in the knee joints, and the Mankin score were assessed. The levels of tumor necrosis factor-α (TNF-α), interleukin-18 (IL-18), and IL-6, as well as the protein expressions of collagen Ⅱ, aggrecan (ACAN), and a disintegrin and metalloproteinase with thrombospondin 5 (ADAMTS5), phosphorylated AMPK (p-AMPK), AMPK, NLRP3, cleaved-caspase-1, and cleaved-IL-1β were detected in the articular cartilage tissue of rats’ knees. RESULTS Compared with OA group, the cartilage tissue defect of jaceosidin group was relieved, the cartilage matrix staining was deepened, and the number of chondrocytes was increased. Knee swelling, Mankin score, the levels of TNF- α, IL-18 and IL-6, and protein expressions of ADAMTS5, NLRP3, cleaved-caspase-1 and cleaved-IL-1β in knee cartilage were significantly decreased or down-regulated. Protein expressions of collagen Ⅱ, ACAN and phosphorylation level of AMPK were significantly increased or up-regulated (P<0.05). Compound C significantly reversed the improvement effects of jaceosidin on the above indexes of OA rats (P<0.05). CONCLUSIONS Jaceosidin may inhibit inflammation and extracellular matrix degradation in OA rats by regulating the AMPK/NLRP3 signaling pathway.

Osteoarthritis (OA) is one of the most prevalent joint disorders, with aging considered a primary, irreversible factor contributing to its progression. Telomere-related cellular senescence may be a crucial factor influencing the OA process, yet biomarkers for OA based on telomere-related genes have not been clearly identified. The datasets GSE51588, GSE12021, and GSE55457 were retrieved from the Gene Expression Omnibus database. Initially, R software was utilized to identify differentially expressed genes between OA and normal samples. Subsequently, differentially expressed telomere-related genes (DETMRGs) were obtained, and their functional enrichment was analyzed. Feature genes for OA diagnosis were selected from DETMRGs using a combination of least absolute shrinkage and selection operator, support vector machine-recursive feature elimination, and Random Forest algorithms. The diagnostic value of these feature genes was then validated through receiver operating characteristic (ROC) curves and decision curve analysis. Additionally, CIBERSORT and xCell were employed to assess the infiltration of immune cells in OA tissues.Finally, potential drugs targeting candidate genes were predicted. Three telomererelated genes, PGD, SLC7A5, and TKT, have been identified as biomarkers for OA diagnosis and were confirmed through ROC diagnostic tests. The immune infiltration of mast cells, neutrophils, common lymphoid precursors, and eosinophils associated with PGD, SLC7A5, and TKT was reduced. Recognizing telomere-related genes PGD, SLC7A5, and TKT as potential diagnostic biomarkers for OA is significant, as it offers valuable insights into the role of telomere-related genes in OA. This discovery also provides valuable information for the diagnosis and treatment of OA.

With the rapid development of social economy and the continuous improvement of human living standard, the incidence, fatality and recurrence rates of cardiovascular disease (CVD) are increasing year by year, which seriously affects people's life and health. Conventional therapeutic drugs have limited improvement on the disability rate, so the search for new therapeutic drugs and action targets has become one of the hotspots of current research. In recent years, the therapeutic role of the natural compound rosmarinic acid (RA) in CVD has attracted much attention, which is capable of preventing CVD by modulating multiple signalling pathways and exerting physiological activities such as antioxidant, anti-apoptotic, anti-inflammatory, anti-platelet aggregation, as well as anti-coagulation and endothelial function protection. In this paper, the role of RA in the prevention of CVD is systematically sorted out, and its mechanism of action is summarised and analysed, with a view to providing a scientific basis and important support for the in-depth exploration of the prevention value of RA in CVD and its further development as a prevention drug.

AIM: To compare the changes in axial length of myopic patients of different ages after wearing orthokeratology lenses with increased compression factor(ICF)or conventional compression factor(CCF)for 2 a.METHODS: Retrospective study. A total of 141 myopia patients(141 right eyes)aged 8 to 15 years who fitted with orthokeratology lenses in the General Hospital of Foshan Aier Eye Hospital from July 2020 to July 2021 were continuously included. They were divided into the CCF group(70 cases, 70 eyes)and the ICF group(71 cases, 71 eyes). The patients in the CCF group were fitted with orthokeratology lens of 0.75 DS CCF, while patients in the ICF group were fitted with orthokeratology lens of 1.25 D ICF. Taking 12 years old as a boundary, these two groups were divided into 8-11 years old and 12-15 years old group. The uncorrected visual acuity(UCVA), horizontal corneal curvature(K1)and corneal staining were recorded for all subjects after wearing lenses for 1 d, 1 wk, 1, 6 mo, 1 and 2 a. The axial length(AL)was recorded after wearing lenses for 6 mo, 1 and 2 a, and the complication and corneal epithelial staining were observed during lens wearing.RESULTS:The improvement of UCVA in the ICF group was faster than that in the CCF group, which were statistical significant after wearing lenses for 1 d, 1 wk and 1 mo, respectively(all P<0.001); however, there was no statistical significance between the two groups after 6 mo, 1 and 2 a(all P>0.05); K1 of the ICF group decreased faster than that of the CCF group, and there were statistical significance at 1 d, 1 wk, and 1 mo after wearing lenses(all P<0.05); there was no statistical significance at 6 mo, 1 and 2 a(all P>0.05). The axial length growth of patients aged 8-11 years old in the ICF group and CCF group was 0.35±0.17 and 0.48±0.26 mm, respectively(P=0.010), after wearing lenses for 2 a, and the axial length growth of patients aged 12-15 years old in the ICF group and CCF group was 0.16±0.15 and 0.31±0.29 mm, respectively(P=0.011). During the follow-up period, corneal spotting occurred in 6 eyes(8.5%)in the ICF group, and 7 eyes(10%)in the CCF group(P>0.05), all of which were grade 1 spotting.CONCLUSION:Wearing ICF orthokeratology lens is more effective than wearing CCF lenses in controlling the growth of axial length, with faster shaping and more obvious improvement in UCVA, especially for the prevention of high myopia in children under 12 years. Therefore, young children can give priority to wearing lenses that increase the compression factor, and for children over 12 years old, the compression factor of the lens can be selectively increased according to the wearer's eye habits, health status of ocular surface and visual function.

BACKGROUND:Osteoporosis is often accompanied by sarcopenia and an increased risk of fractures from falls.Recent studies have indicated a close relationship between lipid metabolism and sarcopenia.Abnormal lipid metabolism may directly impact muscle physiological function and metabolism. OBJECTIVE:To investigate the relationship between lipid metabolism and sarcopenia and evaluate their causal relationship using Mendelian randomization. METHODS:Mendelian randomization was used to explore the causal relationship between low-density lipoprotein cholesterol,high-density lipoprotein cholesterol,triglycerides,and muscle mass.Research data from genome-wide association studies were used and a sensitivity analysis was conducted to verify the reliability of the results.Approximate indicators of muscle mass,including trunk lean mass and appendicular lean mass,were used as outcome measures. RESULTS AND CONCLUSION:The study found a negative correlation of low-density lipoprotein cholesterol and triglycerides with muscle mass,while no correlation was observed between high-density lipoprotein cholesterol and muscle mass.The results of the sensitivity analysis indicated a robust causal relationship.Using Mendelian randomization,this study provides evidence of a causal relationship between low-density lipoprotein cholesterol and triglycerides and muscle mass.This finding deepens our understanding of the effects of lipids on sarcopenia and has important clinical implications for the prevention and treatment of sarcopenia and osteoporosis.
