Aging is an intricate pathophysiological phenotype. It is the result of the combined action of various inflammatory factors and cytokines. Aging is closely related to inflammation, apoptosis, tumors, and other diseases. Anthocyanins are a kind of natural flavonoid, mainly contained in plant fruits such as bilberry, grape, purple sweet potato, and so on. These flavonoids have antioxidation, antiaging, and anti‐inflammatory properties. It has been found that anthocyanins can effectively delay liver, ovary, and other organ aging. However, the biological mechanism by which anthocyanins alleviate aging phenotypes is still poorly understood. To simulate liver aging in mice, D‐galactose was injected daily at 800 mg/kg to accelerate aging, and anthocyanins at 20 or 40 mg/kg were given as intervention treatments. The antiaging effect of anthocyanins was evaluated by body weight, inflammatory markers, and aging markers. Serum ALT and AST levels were measured, and liver histology was assessed using hematoxylin–eosin staining. In addition, we explored the molecular mechanism of anthocyanins delaying liver aging by detecting the expression levels of NF‐κB/IKK signaling protein molecules. Our results indicate that anthocyanins can effectively delay mouse liver senescence induced by D‐galactose. Analyses by Western blot demonstrated that anthocyanins inhibited the NF‐κB/IKK signaling pathway, thereby inhibiting inflammation. In vitro, anthocyanins attenuate the D‐galactose (D‐gal)–induced aging in AML12 cells, as indicated by reduced aging‐associated p21 and p16. Anthocyanins can similarly inhibit the NF‐κB/IKK signal pathway in D‐gal–induced aging in AML12 cells. Based on these findings, anthocyanins reduce liver aging in mice by regulating the NF‐κB/IKK pathway.

Background Patients with knee osteoarthritis (KOA) often experience persistent pain and functional impairment after total knee arthroplasty (TKA), which presents challenges for pain management. Accurate preoperative assessment of pain characteristics is crucial for tailoring individualized treatment plans. The PainDETECT Questionnaire has been widely used to identify neuropathic components in chronic pain and has been validated for its reliability and validity across various cultural contexts. However, a culturally adapted version tailored to Chinese patients is currently lacking. This study aims to translate and culturally adapt PainDETECT for Chinese patients and evaluate its validity in TKA patients in China. Methods This study followed international guidelines to translate and adapt the PainDETECT Questionnaire (PDQ) into Chinese (PDQ-CV). A cohort of 241 knee osteoarthritis (KOA) patients completed the PDQ-CV, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), EuroQol-5 Dimensions-5 Levels (EQ-5D-5 L), and Central Sensitization Inventory Chinese Version (CSI-CV). We assessed internal consistency using Cronbach’s alpha and test-retest reliability via intraclass correlation coefficient (ICC). Construct and structural validity were evaluated through Pearson correlations and factor analyses. Results The PDQ-CV demonstrated good acceptability among KOA patients, with no floor or ceiling effects observed. Internal consistency was high (Cronbach’s α = 0.896), and test-retest reliability was excellent (ICC = 0.994; 95% CI: 0.943–1.045). The PDQ-CV total score showed significant positive correlations with WOMAC (r = 0.589, P < 0.01), EQ-5D-5 L (r = 0.533, P < 0.01), and CSI-CV (r = 0.776, P < 0.01). Exploratory factor analysis (EFA) extracted two primary factors, corresponding to the sensory dimension (52.1% variance) and the affective dimension (16.3% variance), explaining a total variance of 68.4%. Conclusion The PDQ-CV demonstrated good feasibility, reliability, and validity in Chinese KOA patients, supporting its use in clinical practice and providing a foundation for future research.

Background Colorectal cancer (CRC) exhibits a high incidence globally, with the liver being the most common site of distant metastasis. At the time of diagnosis, 20–30% of CRC patients already present with liver metastases. Colorectal liver metastasis (CRLM) is a major cause of mortality among CRC patients. The pathogenesis of CRLM involves complex molecular mechanisms and the hepatic immune microenvironment, but current clinical prevention and treatment are significantly limited. Recent studies have revealed that the major facilitator superfamily domain containing protein-2a (Mfsd2a) plays a pivotal role in the development and metastasis of various cancers. For instance, Mfsd2a inhibits gastric cancer initiation and progression and may impact angiogenesis. However, the mechanisms by which Mfsd2a influences CRC progression and liver metastasis remain unclear. Methods In this study, we conducted a survival analysis of Mfsd2a in colorectal cancer using data from the GEPIA and GEO databases, and examined the expression differences between primary tumor (PT) and liver metastasis (LM). We further assessed the clinical significance and prognostic relevance of Mfsd2a through immunohistochemical analysis of tissue samples from 70 CRLM patients. Moreover, Kaplan-Meier analysis was used to perform survival analysis on these patients. The biological function of Mfsd2a in CRLM was confirmed by a series of experiments conducted both in vitro and in vivo. Additionally, we investigated downstream molecular pathways using western blot, Co-immunoprecipitation, immunofluorescence, and mass spectrometry techniques. Results We observed that Mfsd2a expression is reduced in LM compared to PT, and higher Mfsd2a levels are associated with better prognosis in CRLM patients. Furthermore, function assays demonstrated that Mfsd2a suppresses CRC cells proliferation, migration, invasion, and EMT in vitro, while also delaying tumor growth and liver metastasis in vivo. Mechanistically, Mfsd2a interacts with S100A14, enhancing its expression and inhibiting phosphorylation of STAT3. In addition, the STAT3 activator colivelin partially reversed the inhibitory effect of Mfsd2a overexpression on the progression of colorectal cancer and liver metastasis. Conclusion In summary, Mfsd2a inhibits colorectal cancer progression and liver metastasis by interacting with S100A14, thereby suppressing the phosphorylation of STAT3. Mfsd2a functions as a tumor suppressor in CRLM and could be a promising therapeutic target for treating CRC patients with liver metastasis. Graphical abstract

Purpose Patient-reported outcome measures (PROMs) are being used more frequently in total knee arthroplasty (TKA). By utilizing high-quality scales, surgeons can achieve a more comprehensive and accurate evaluation of the effectiveness of TKA surgery. Currently, there is no widely accepted conceptual model for TKA PROMs. The objective of this study is to fill this gap by developing a conceptual model and preliminary content for a PROM that is specifically designed for TKA patients in mainland China. Methods The study design consisted of three stages: (1) a targeted literature review followed by the formation of a conceptual model pool; (2) qualitative data collection involving experts and patients, leading to the development of the preliminary Chinese TKA PROM (CTP); and (3) review of the CTP by experts using the Delphi method, along with cognitive debriefing interviews with patients. Results 64 patients and 28 experts took part in this study. The conceptual model focused on six key concepts: pain, symptom, function, quality of life, expectation, and satisfaction. To match the model, the authors developed a total of 35 items. Conclusion A conceptual model and preliminary content for CTP was developed with substantial participation from patients and a multidisciplinary group of experts. The integration of patient and clinical perspectives ensured a comprehensive representation of all relevant disease experiences and the focus of clinical practice. With further refinement through psychometric testing, the CTP is positioned to provide a standardized, comprehensive measure for research specific to Chinese TKA patients.

Background Sodium-glucose cotransporter 2 (SGLT2) inhibition is recognized for its evident renoprotective benefits in diabetic renal disease. Recent data suggest that SGLT2 inhibition also slows down kidney disease progression and reduces the risk of acute kidney injury, regardless of whether the patient has diabetes or not, but the mechanism behind these observed effects remains elusive. The objective of this study is to utilize a mendelian randomization (MR) methodology to comprehensively examine the influence of metabolites in circulation regarding the impact of SGLT2 inhibition on kidney function. Methods We used a MR study to obtain associations between genetic proxies for SGLT2 inhibition and kidney function. We retrieved the most recent and comprehensive summary statistics from genome-wide association studies (GWAS) that have been previously published and involved kidney function parameters such as estimated glomerular filtration rate (eGFR), urine albumin-to-creatinine ratio (UACR), and albuminuria. Additionally, we included blood metabolite data from 249 biomarkers in the UK Biobank for a more comprehensive analysis. We performed MR analyses to explore the causal relationships between SGLT2 inhibition and kidney function and two-step MR to discover potential mediating metabolites. Results The study found that a decrease in HbA1c levels by one standard deviation, which is genetically expected to result in SGLT2 inhibition, was linked to a decreased likelihood of developing type 2 diabetes mellitus (T2DM) (odds ratio [OR] = 0.55 [95% CI 0.35, 0.85], P = 0.007). Meanwhile, SGLT2 inhibition also protects eGFR (β = 0.05 [95% CI 0.03, 0.08], P = 2.45 × 10− 5) and decreased UACR (-0.18 [95% CI -0.33, -0.02], P = 0.025) and albuminuria (-1.07 [95% CI -1.58, -0.57], P = 3.60 × 10− 5). Furthermore, the study found that of the 249 metabolites present in the blood, only one metabolite, specifically the concentration of small high-density lipoprotein (HDL) particles, was significantly correlated with both SGLT2 inhibition and kidney function. This metabolite was found to play a crucial role in mediating the improvement of renal function through the use of SGLT2 inhibition (β = 0.01 [95% CI 0.005, 0.018], P = 0.001), with a mediated proportion of 13.33% (95% CI [5.71%, 26.67%], P = 0.020). Conclusions The findings of this investigation provide evidence in favor of a genetically anticipated biological linkage between the inhibition of SGLT2, the presence of circulating metabolites, and renal function. The findings demonstrate that the protective effect of SGLT2 inhibition on renal function is mostly mediated by HDL particle concentrations in circulating metabolites. These results offer significant theoretical support for both the preservation of renal function and a better comprehension of the mechanisms underlying SGLT2 inhibition.

Background Neglected congenital clubfoot (NCCF) is a birth deformity that remains untreated until the child begins to walk. Irrespective of the treatment protocols employed, children with NCCF face an elevated risk of recurrence following the initial correction. Predicting this recurrence could enable early intervention for high-risk children, ultimately diminishing the likelihood of invasive surgery. Methods From January 2006 to January 2022, a total of 33 unilateral NCCF patients were enrolled in this study at Xijing Hospital. Pedobarographic tests were performed at three distinct time points: after the initial Ponseti treatment, before recurrence treatment, and after recurrence treatment. Four derivative parameters were developed for predicting recurrence, namely the difference of the contact time% (DCT%), difference of the contact area% (DCA%), difference of the peak pressure (DPP), and difference of the pressure-time integral (DPTI) between the two feet. ROC curves, Kaplan-Meier survival analysis, and Cox regression were employed to identify potential prognostic factors. Results Out of the 33 unilateral NCCF patients, recurrence occurred in 8 individuals, with an average follow-up period of 109.8 months. The predictive parameter for recurrence is the midfoot (MF) zone's DCT% (MF-DCT%). When the contact time (CT)% of the affected side was 20.69% higher than that of the unaffected side, the hazard ratio (HR) of recurrence increased by 7.404 times. Another predictive plantar pressure parameter is the DPP in the MF zone (MF-DPP). If the PP of the affected side was 159% higher than that of the unaffected side, the HR of recurrence increased by 9.229 times. The MF-DCT% and MF-DPP of recurrence patients were assessed at three time points for comparisons, further validating their predictive ability for recurrence. Conclusion Although satisfactory clinical outcomes were achieved in patients with unilateral NCCF after the initial Ponseti treatment, the plantar pressure distribution does not return to normal levels, which may indicate future recurrence. DCT% and DPP in the MF zone can be used as plantar pressure predictors of recurrence in patients with NCCF.

Background In recent decades, there have been notable advancements in the field of analgesia and total knee arthroplasty (TKA). This study aims to employ bibliometric analysis to elucidate the prevailing research focal points and trends within analgesia and TKA from 1990 to 2022. Material and methods Relevant publications were retrieved from the Web of Science Core Collection. CiteSpace, VOSviewer, and Scimago Graphica were used for visualization and bibliometric analysis of countries, institutions, authors, journals, references, and keywords. Results A total of 2776 publications on analgesia and TKA were identified, with the United States having the highest number of publications. The University of Copenhagen was the most productive institution, and Kehlet, Henrik was the most prolific author. The Journal of Arthroplasty had the most publications and citations. The most common keywords were “TKA,” “pain management,” “postoperative pain,” “Total hip arthroplasty (THA),” and “postoperative management.” Keyword burst detection demonstrated that adductor canal block (ACB) was a recent research hotspot. Conclusion Our study revealed a sharp increase in global publications on analgesia and TKA, and this trend is expected to continue. Further research is necessary to determine the optimal regimen for multimodal analgesia, the ideal location and volume of ACB, and their clinical significance.

Background Liver cancer due to hepatitis C (LCDHC) is one of the leading causes of cancer-related deaths worldwide, and the burden of LCDHC is increasing. We aimed to report the burden of LCDHC at the global, regional, and national levels in 204 countries from 1990 to 2019, stratified by etiology, sex, age, and Sociodemographic Index. Methods Data on LCDHC were available from the Global Burden of Disease, Injuries, and Risk Factors (GBD) study 2019. Numbers and age-standardized mortality, incidence, and disability-adjusted life year (DALY) rates per 100,000 population were estimated through a systematic analysis of modeled data from the GBD 2019 study. The trends in the LCDHC burden were assessed using the annual percentage change. Results Globally, in 2019, there were 152,225 new cases, 141,810 deaths, and 2,878,024 DALYs due to LCDHC. From 1990 to 2019, the number of incidences, mortality, and DALY cases increased by 80.68%, 67.50%, and 37.20%, respectively. However, the age-standardized incidence, mortality, and DALY rate had a decreasing trend during this period. In 2019, the highest age-standardized incidence rates (ASIRs) of LCDHC were found in high-income Asia Pacific, North Africa and the Middle East, and Central Asia. At the regional level, Mongolia, Egypt, and Japan had the three highest ASIRs in 2019. The incidence rates of LCDHC were higher in men and increased with age, with a peak incidence in the 95+ age group for women and the 85–89 age group for men in 2019. A nonlinear association was found between the age-standardized rates of LCDHC and sociodemographic index values at the regional and national levels. Conclusions Although the age-standardized rates of LCDHC have decreased, the absolute numbers of incident cases, deaths, and DALYs have increased, indicating that LCDHC remains a significant global burden. In addition, the burden of LCDHC varies geographically. Male and older adult/s individuals have a higher burden of LCDHC. Our findings provide insight into the global burden trend of LCDHC. Policymakers should establish appropriate methods to achieve the HCV elimination target by 2030 and reducing the burden of LCDHC.
