Objective To analyze the disease burden of early-onset colorectal cancer (EOCRC) at the global, regional, and national levels from 1990 to 2021, and to predict the disease burden trend from 2022 to 2026. Methods Based on the Global Burden of Disease (GBD) database, the incidence, mortality, and disability-adjusted life year (DALY) rate of EOCRC across 204 countries and regions from 1990 to 2021 were obtained. The time trends of these indicators were assessed by calculating the estimated annual percentage change (EAPC), and the contributions of ten risk factors to the EOCRC burden were analyzed. The autoregressive integrated moving average (ARIMA) model was used to predict the disease burden from 2022 to 2026. Results From 1990 to 2021, the number of new global EOCRC cases increased from 107 310 to 211 890, with the incidence rising from 3.96 to 5.37 per 100 000 people. In 2021, global EOCRC incidence, mortality, and DALY rate increased with age; males had higher rates than females in terms of incidence, mortality, and DALY rate in all age groups. In 2021, East Asia had the highest number of new cases, deaths, and DALY. From 1990 to 2021, the global EAPC for incidence rate was 0.96%, and death rate was –0.38%. ARIMA model indicated that from 2022 to 2026, the global incidence of EOCRC would continue to rise, while mortality and DALY rate would be expected to decline. Conclusions The disease burden of EOCRC has significantly increased globally from 1990 to 2021, with notable regional, age, and sex differences. By 2026, the mortality and DALY rate of EOCRC will decline, while the incidence is expected to further increase, highlighting the urgency of taking active measures to address the growing trend of EOCRC.

ChuanWu (CW), the dried mother root of Aconitum carmichaelii Debx., is a well-known traditional Chinese medicine (TCM) recognized for its potent efficacy but inherent toxicity, primarily due to its alkaloid content. Traditional and modern detoxification methods for CW include proper processing, rational compatibility, and specialized decoction techniques, among which honey-boiled CW is particularly distinctive. However, research on the detoxification mechanism of honey-boiled CW remains limited. This study investigated this mechanism by analyzing alkaloid transformation and supramolecular aggregation. Honey-boiled and water-boiled CW preparations were compared. Ultra-high-performance liquid chromatography-tandem mass spectrometry was used to analyze CW alkaloids, specifically diester alkaloids (DDAs), monoester alkaloids (MDAs), and non-esterified diterpenoid alkaloids (NDAs). Transmission electron microscopy was employed to observe and identify supramolecular aggregates in the honey-boiled CW decoction. In vivo absorption of water-boiled, honey-boiled, and NADES-boiled CW was compared. Median lethal dose (LD50) tests assessed toxicity, including hepatotoxicity and nephrotoxicity. In vitro experiments evaluated the safety, anti-inflammatory, and analgesic effects of CW-medicated serum on RAW264.7 cells, with in vivo validation in mice. Results showed that honey promoted the conversion of highly toxic DDAs to less toxic MDAs and prevented MDAs from hydrolyzing into NDAs. Honey-boiled CW formed approximately 250 nm supramolecular aggregates that encapsulated MDAs, inhibiting their conversion to NDAs. These encapsulated MDAs acted as a stable delivery system with higher bioavailability than free benzoylmesaconine. Subsequent mouse experiments confirmed that honey-boiled CW significantly increased the LD50 of CW while reducing hepatotoxicity and nephrotoxicity. Additionally, honey-boiled CW significantly improved cell safety and enhanced anti-inflammatory and analgesic effects. Our findings reveal that honey-boiled CW exhibits a potent detoxification mechanism by influencing alkaloid transformation and facilitating the formation of supramolecular aggregates. This study lays the groundwork for developing detoxification or synergistic strategies within honey-boiled TCM.

Objective To investigate the prevalence and risk factors of work-related musculoskeletal disorders (WMSDs) among construction workers. Methods A total of 5 783 workers were selected as participants from 12 construction companies in Guangdong Province, Guangxi Zhuang Autonomous Region and Zhejiang Province using a convenient sampling method. The revised Musculoskeletal Disorders Questionnaire was used to investigate the prevalence and influencing factors of WMSDs. Results The prevalence of WMSDs was 27.4% among the construction workers. The prevalence of WMSDs in shoulder, neck, waist/lower back and hand/wrist was 10.6%, 9.5%, 9.5% and 9.4% respectively, which was higher than that in other body parts. Bianry logistic regression analysis showed that the risk of WMSDs in construction workers with junior high school education and below was higher than that of high school/ college and above (P<0.05). The risk of WMSDs was higher in drinkers than that in non-drinkers (P<0.01). The worse the health status of construction workers, the higher the risk of WMSDs (P<0.01). The risk of WMSDs in those who exercised once or twice a month was lower than that in those who did not exercise (P<0.05). The risk of WMSDs was higher in construction workers with longer working hours in uncomfortable postures and greater back bending amplitude at work (all P<0.01). The risk of WMSDs in construction workers with hands holding above the shoulder was higher than that with hands below the shoulder (P<0.05). Construction workers who repeated the same work daily, involved in high-temperature work, often worked overtime, had insufficient rest time, and had a shortage of department personnel had a relatively high risk of WMSDs (all P<0.01). Conclusion The prevalence of WMSDs among the construction workers was relatively high, and the most common WMSDs occurred in shoulder, neck, waist/lower back and hand/wrist. Individual characteristic, work type, work posture and work organization are the influencing factors of WMSDs. Comprehensive measures, especially ergonomic measures based on personal and occupational characteristics should be taken to reduce the risk of WMSDs among construction workers.

AIM:To investigate the impact of platycodin D(PD)on the viability,migration,invasion,apop-tosis and cell cycle of osteosarcoma cells in vitro,along with its underlying mechanisms.METHODS:Human osteosarco-ma cells MG63 and U2OS were divided into control group(0 μmol/L)and PD treatment group(6.25,12.5,25,50 and 100 μmol/L,respectively).Human osteosarcoma cells MG63 and U2OS were categorized into control groups(0 μmol/L PD)and PD treatment groups(6.25,12.5,25,50 and 100 μmol/L).The CCK-8 assay determined cell viability and identified effective treatment concentrations.MG63(15 μmol/L PD)and U2OS(25 μmol/L PD)were specifically ana-lyzed.Cell scratch and Transwell assays assessed migration and invasion.Hoechst 33342 staining examined nuclear mor-phological changes.Flow cytometry analyzed cell cycle distribution and apoptosis rate.Western blot measured protein ex-pression levels:cleaved caspase-3,cleaved PARP,c-Jun N-terminal kinase(JNK),p-JNK,B-cell lymphoma-2(Bcl-2),Bcl-2-ssociated X protein(BAX),matrix metalloproteinase 2(MMP-2),MMP-9,cyclin-dependent kinase 4(CDK4),cyclin D1,CDK1,cyclin B1,extracellular signal-regulated kinase(ERK)and p-ERK.Proteome sequencing of MG63 cells was performed.RESULTS:PD treatment significantly decreased cell survival,scratch healing rate,and invasive cell numbers,while increasing apoptosis rates(P<0.05).Morphological changes such as nuclear hyperchroma-tism and fragmentation were observed in PD-treated cells.PD induced G2/M phase arrest in MG63 and G0/G1 phase arrest in U2OS cells.PD treatment upregulated BAX,cleaved caspase-3,cleaved PARP,and p-JNK/JNK,while downregulat-ing Bcl-2,MMP-2,MMP-9,CDK4,cyclin D1,CDK1,cyclin B1,and p-ERK/ERK(P<0.05).Proteome sequencing re-vealed PD's involvement in cell division,cell cycle regulation,focal adhesion,apoptosis,and the MAPK signaling path-way.CONCLUSION:PD inhibits cell viability,migration,and invasion of osteosarcoma cells in vitro,while promoting apoptosis and inducing cell cycle arrest.These effects are likely mediated through modulation of the MAPK signaling path-way.
