Objective To construct a lung cancer surgery-oriented disease-specific database covering the entire perioperative care pathway, thereby improving the quality and usability of key surgical data elements. Methods Real-world clinical data were extracted from a single-center thoracic surgery department. A standardized data model was established based on the open electronic health record (openEHR) standard. Large language model (LLM), optical character recognition (OCR), and artificial intelligence (AI)-driven techniques were employed to extract, structure, and perform quality control on unstructured clinical narratives, imaging reports, and radiological data, with a focus on capturing surgically relevant perioperative indicator. Results A multimodal database comprising 19 917 patients was established, including 7 930 males and 11 987 females, with ages ranging from 15 to 97 (61.7±9.7) years. The database includes 582 structured data variables, textual report data corresponding to 69 clinical indicators, 13 000 pulmonary function test PDF reports, and chest CT imaging data from 16 884 patients. This database comprehensively covers major information relevant to surgical diagnosis and treatment of lung cancer, significantly improving the completeness and granularity of surgical detail data. Large language models (LLMs) and optical character recognition (OCR) technologies enhanced the efficiency of converting unstructured data into structured formats, while a multi-level manual verification process ensured data accuracy and traceability. The database supports real-world research including comparisons of surgical procedures, prediction of postoperative complications, prognosis assessment, and multimodal data association analyses.

OBJECTIVE To investigate the mechanism of Qushi huoxue decoction in improving metabolic-associated fatty liver disease （MAFLD） based on the AMP-activated protein kinase/mammalian target of rapamycin/UNC-51-like kinase 1 （AMPK/mTOR/ULK1） autophagy signaling pathway.METHODS Male C57BL/6J mice were randomly divided into normal group， model group， and low-， medium-， and high-dose Qushi huoxue decoction groups [4.10， 8.20， 16.40 mg/（g·d）]， with 10 mice in each group. Except for the normal group， mice in the other groups were fed a high-fat diet for 12 weeks to establish the MAFLD model. Starting 24 hours after modeling， mice in each group were administered the drug solution or normal saline once daily for 6 consecutive weeks. Serum levels of total cholesterol （TC）， triglycerides （TG）， alanine transaminase （ALT）， aspartate transferase （AST）， low-density lipoprotein cholesterol （LDL-C）， and high-density lipoprotein cholesterol （HDL-C） were detected according to the kit instructions. Hematoxylin-eosin （HE） staining and oil red O staining were used to observe pathological changes in mouse liver tissue. Western blot and immunofluorescence staining were used to detect the expression and positive protein expression related to the AMPK/mTOR/ULK1 autophagy signaling pathway.RESULTS Compared with the normal group， the serum levels of TC， TG， ALT， AST， and LDL-C in the model group were significantly increased， while the HDL-C level was significantly decreased （ P ＜0.01）. HE staining showed obvious steatosis in hepatocytes of the model group， and oil red O staining showed a large amount of lipid droplet accumulation in liver tissue. Western blot and immunofluorescence staining results showed that the expression levels of p-mTOR/mTOR and p62 proteins， as well as the relative fluorescence intensities of p-mTOR and p62 proteins in liver tissue of the model group， were significantly increased/enhanced （ P ＜0.01）， while the expression levels of p-AMPK/AMPK， ULK1， and microtubule-associated protein 1 light chain 3Ⅱ （LC3Ⅱ） proteins， as well as the relative fluorescence intensities of p-AMPK and LC3 proteins， were significantly decreased/weakened （ P ＜0.01）. After intervention with Qushi huoxue decoction， the above pathological changes and abnormal indicators in liver tissue of mice in the low-， medium-， and high-dose groups were significantly reversed， with most indicators showing statistically significant differences （ P ＜0.05 or P ＜0.01）.CONCLUSIONS Qushi huoxue decoction can significantly improve liver pathology， blood lipid levels， and liver function in MAFLD model mice； this improvement may be achieved through the activation of the AMPK/mTOR/ULK1 autophagy signaling pathway.

Metabolic dysfunction-associated fatty liver disease （MAFLD） is a common chronic liver disease with the pathological feature of lipid accumulation in the liver， and it is closely associated with liver metabolic disorders. The latest research has shown that the pathogenesis of MAFLD is associated with the abnormal expression of specific genes， especially the fat mass and obesity-associated （FTO） gene. The abnormal activity of the FTO gene may lead to an imbalance in liver lipid metabolism， which manifests as the increase in fatty acid synthesis and the reduction in fatty acid oxidation， thereby promoting liver fat deposition and inflammatory response. Therefore， regulating the expression or activity of the FTO gene is considered one of the potential strategies for the treatment of MAFLD. At present， drug research targeting the function of the FTO gene has achieved preliminary results， and inhibition of the activity of the FTO gene can help to regulate liver lipid metabolism and alleviate liver inflammatory injury. This article reviews the mechanism of action of the FTO gene in the development and progression of MAFLD， summarizes the advances in drug research on the FTO gene and related metabolic pathways in recent years， and analyzes their application prospect in research and treatment.

Objective To analyze the elevated blood pressure status and its influencing factors among manufacturing workers in Foshan City. Methods A total of 565 795 manufacturing workers who underwent occupational medical examinations in Foshan City from 2017 to 2023 were included. Data of workers were obtained from the Guangdong Provincial Key Occupational Disease Monitoring and Management Platform. The influencing factors of elevated blood pressure were analyzed using descriptive epidemiological methods. Results A total of 89 526 cases of elevated blood pressure were detected among the 565 795 workers, with a detection rate of 15.82%. From 2017 to 2023, the annual detection rate of elevated blood pressure was 14.11%, 15.00%, 14.69%, 15.94%, 17.00%, 16.90%, and 16.68%, respectively, showing an overall upward trend (P<0.01). The top three industries with the highest detection rates of elevated blood pressure were instrument and meter manufacturing; wood processing and the manufacture of wood, bamboo, rattan, palm, and straw products; as well as agricultural and sideline food processing. Binary logistic regression analysis showed that male workers had a higher risk of elevated blood pressure than female workers (P<0.01). The risk of elevated blood pressure in workers increased with age, years of occupational hazard exposure, and duration of dust exposure (all P<0.05). Workers exposed to noise for more than three years had a higher risk of elevated blood pressure than those without noise exposure (P<0.05). The risk of elevated blood pressure among workers in Nanhai, Shunde, and Gaoming districts was higher than that in Chancheng District (all P<0.01). Workers originating from Northeast and Northwest China had a higher risk of elevated blood pressure than those from North China (all P<0.05). Workers from smaller-scale enterprises had higher risk of elevated blood pressure (all P<0.01). Conclusion Targeted blood pressure health interventions in Foshan City should be strengthened for male manufacturing workers who are older, have longer working years, and originate from Northeast and Northwest China. The development of exemplary health enterprises should be promoted, particularly among micro- and small-sized enterprises and key industries. Enhanced occupational health management is especially needed for positions with high intensity noise exposure and high concentration dust exposure.

Background::Hepatitis B poses a heavy burden for children in China, however, the national studies on the distributional characteristics and health care costs of children with severe hepatitis B is still lacking. This study aimed to analyze the disease characteristics, health economic effects, and medical cost for children with severe hepatitis B in China.Methods::Based on patient information in the Hospital Quality Monitoring System, cases with severe hepatitis B were divided into four groups according to age, and the etiology and symptoms of each group were quantified. The cost of hospitalization was calculated for cases with different disease processes, and severity of disease. The spatial aggregation of cases and the relationship with health economic factors were analyzed by Moran’s I analysis. Results::The total number of children discharged with hepatitis B from January 2016 to April 2022 was 1603, with an average age of 10.5 years. Liver failure cases accounted for 43.48% (697/1603) of total cases and cirrhosis cases accounted for 11.23% (180/1603). According to the grouping of disease progression, there were 1292 cases without associated complications, and the median hospitalization cost was $818.12. According to the spatial analysis, the aggregation of cases was statistically significant at the prefectural and provincial levels in 2019, 2020, and 2021 (all P <0.05). The number of severe cases was negatively correlated with gross domestic product (Moran’s I <0) and percentage of urban population (Moran’s I <0), and positively correlated with the number of pediatric beds per million population (Moran’s I >0). Conclusion::The number of severe hepatitis B cases is low in areas with high gross domestic product levels and high urban population ratios, and health care costs have been declining over the years.

This study aims to investigate the relationship between serum vitamin A(VA)and mar-bling grade and the effect of different levels of serum VA on slaughter performance and fatty acid composition and related gene expression in the longissimus dorsi muscle of Woking black cattle and Angus cattle.Thirty Woking black cattle and seventeen Angus cattle aged 30 months were ran-domly selected and analyzed for the linear relationship between serum VA and marbling grade af-ter slaughter.The cattle were divided into three groups:the low VA group,medium VA group and high VA group,ranked in order of VA value in both Woking black cattle and Angus cattle.Statisti-cal analysis of the effects of different types and levels of VA on marbling grade,slaughter performance,fatty acid composition,and the effects of different levels of VA on the expression of genes related to intramuscular fat deposition and other genes in Woking black cattle or Angus cat-tle were also analyzed.The results showed that the marbling grade of Woking black cattle increased numerically with increasing serum VA at slaughter(P=0.203),whereas Angus cattle showed a numerical decrease(P=0.139).Analyses of subsequent subgroups showed that Woking black cat-tle had significantly higher marbling grade and oleic acid,monounsaturated/saturated fatty acids ratio in the longissimus dorsi muscle compared to Angus cattle(P＜0.05).As serum VA levels in-creased,DHA was significantly higher and n-6/n-3 fatty acid ratio significantly lower in the longis-simus dorsi muscle of Woking black cattle(P＜0.05).Whereas VA was elevated in Angus cattle,a significant decrease in DHA and a significant increase in n-6/n-3 fatty acids(P＜0.05)were found.Furthermore,a notable up-or down-regulation(P＜0.05)of LPL,FABP4,PPARγ,C APZA2 and Villin 2 was observed in Woking black or Angus cattle,respectively,as VA levels increased.Based on these results,it was suggested that Woking black cattle require an appropriate increase in dieta-ry VA during the late fattening stage,which was found to produce a higher marbling grade and a higher percentage of beneficial fatty acids for human health when serum VA reached 80.7 IU/dL.Whereas Angus cattle still need to be restricted in ration VA content in the late fattening stage,when serum VA is elevated to 73.6 IU/dL,they produce beef that not only has a lower marbling grade but also has a corresponding reduction in fatty acids beneficial to human health.

Objective:To analyze the influencing factors of skull base reconstruction failure after endoscopic endonasal skull base surgery (EESBS).Methods:A retrospective analysis was performed on 228 EESBS cases at the Affiliated Hospital of Qingdao University from 2018 to 2023. The clinical features associated with skull base reconstruction and postoperative cerebrospinal fluid leakage were collected and analyzed. Lasso regression was initially used for exploratory analysis, and risk factors for reconstruction failure were subsequently evaluated using multifactorial logistic regression.Results:A total of 157 cases of EESBS were included, with an overall reconstruction failure rate of 11.5% (18/157). No patients who underwent second-stage reconstruction with a tipped mucosal flap or multilayered free mucosal and fascial repair experienced further postoperative cerebrospinal fluid leakage. Variables identified through Lasso regression included history of surgery, history of radiotherapy, and site of leakage. Multifactorial logistic analysis showed that history of radiotherapy ( OR=5.96, P=0.021) and site of leakage in the posterior skull base ( OR=8.70, P=0.003) were significant risk factors for failure of skull base reconstruction. Conclusion:In cases with a history of radiotherapy and/or posterior skull base lesions in the operative area, reconstruction strategies should be strengthened to improve the success rate of one-stage repair, in particular, when intraoperative cerebrospinal fluid leakage occurs.
