Objective:To compare the safety and efficacy of transarterial chemoembolization (TACE) combined with donafenib and programmed death protein 1 (PD-1) inhibitors and TACE combined with donafenib in the treatment of unresectable hepatocellular carcinoma (uHCC).Methods:Clinical data of 148 patients with uHCC treated at the First Affiliated Hospital of Zhengzhou University from December 2021 to December 2022 were retrospectively analyzed, including 127 males and 21 females, aged (56.6±9.9) years. Patients were divided into two groups: the TACE combined with donafenib and PD-1 inhibitors group (TACE+ DP, n=73) and TACE combined with single donafenib (TACE+ D, n=75). The overall survival (OS), progression-free survival (PFS), objective response rate (ORR), disease control rate (DCR), and the occurrence of treatment-related adverse events (TRAEs) of the two groups of patients were observed. Kaplan-Meier analysis was used for survival assessment, and the log-rank test was used for comparison. The related factors affecting the prognosis of patients were indentified and analyzed. Results:The median PFS of patients in the TACE+ D group and the TACE+ DP group were 7.2 months (95% CI: 5.7-8.3 months) and 10.5months (95% CI: 8.9-11.3 months), respectively. The median OS was 13.2 months (95% CI: 12.3-13.7 months) and 16.9 months (95% CI: 15.1-19.8 months), respectively. All these differences were statistically significant ( χ2=17.81, 26.92, respectively, both P<0.001). The ORR and DCR of TACE+ DP group were both higher than those in TACE+ D group [53.4% (39/73) vs 36.0% (27/75), χ2=4.55, P=0.031; and 90.4% (66/73) vs 77.3% (58/75), χ2=4.66, P=0.044]. No grade 4 or above adverse events occurred in either the TACE+ DP or the TACE+ D group. The most common treatment-related adverse events in TACE+ D and TACE+ DP group were hand-foot syndrome [46.7% (35/75) vs 49.3% (36/73)], hypertension [26.7% (20/75) vs 30.1% (22/73)], fatigue [22.7% (17/75) vs 24.7% (18/73)], diarrhea [26.7% (20/75) vs 28.8% (21/73)], and thrombocytopenia [25.3% (19/75) vs 28.8% (21/73)]. There was no significant difference in the incidence and severity of TRAEs between the groups ( χ2=0.08, P=0.774). TACE+ DP treatment was a favorable prognostic factor for PFS ( HR=0.33, 95% CI: 0.22-0.49, P<0.001) and OS ( HR=0.19, 95% CI: 0.11-0.33, P<0.001) of patients. Conclusion:Compared to TACE combined with donafenib, TACE combined with donafenib and PD-1 inhibitors, with good efficacy and safety, significantly improved the treatment response and survival in patients with uHCC.

Objective:To explore the structural equation model to explore the levels of work-related musculoskeletal disorders (WMSDs) and various risk factors in the feet and ankle of China's occupational population, providing scientific basis for for preventing WMSDs in feet and ankles.Methods:Data of 73497 national occupational epidemiological cases were selected from June 2018 to December 2023 used the Chinese version of the Electronic Questionnaire on Musculoskeletal Disorders. The adverse ergonomic factors and their source classification standard and confirmatory factor analysis were used to investigate foot and ankle WMSDs and their related risk factors (including individual factors, work organization, work posture, work type, fatigue, etc.) in key occupational groups in China, and structural equation model hypothesis, fitting, verification, and path and intermediary effect analysis were carried out. The model fit evaluation indexes included Chi-square specific degrees of freedom ( χ2/ df), gauge fit index (NFI), Tucker Lewis index (TLI), goodness of Fit index (GFI), adjusted Goodness of Fit index (AGFI) and approximate root mean square error (RMSEA) . Results:A total of 73497 occupational workers were surveyed, with local muscle fatigue and WMSDs incidence rates in the feet and ankles being 17.17% and 12.06%, respectively. The fitting index of the adjusted structural equation model basically meets the standard (GFI=1, AGFI=1, RMESA=0.042, NFI=0.716, TLI=0.663). The top three factors affecting feet and ankle WMSDs are feet and ankle muscle fatigue, work type, and work organization, with standardized path coefficients of 0.221, 0.105, and 0.095, respectively. The top two factors affecting feet and ankle muscle fatigue are work organization and work type, with standardized path coefficients of 0.548 and 0.383, respectively. Feet and ankle muscle fatigue, work type, work organization, and work posture have a direct effect on feet and ankle WMSDs, with effect values of 0.221, 0.105, 0.095, and 0.077, respectively. The organization and type of work can also have indirect effects through feet and ankle muscle fatigue, with effect values of 0.121 and 0.084, respectively.Conclusion:Feet and ankle muscle fatigue has a direct impact on WMSDs, and plays a mediating role between ankle and ankle WMSDs caused by work organization and work type. Feet and ankle muscle fatigue is an important pathway leading to feet and ankle WMSDs. It is recommended that employers and managers detect job fatigue early and take corresponding prevention and intervention measures, which can play a key role in preventing feet and ankle WMSDs.

Objective:To explore the structural relationship between WMSDs in the upper limbs and various risk factors in the occupational population in China, based on a large sample epidemiological survey and structural equation analysis, and to establish a structural equation model, so as to lay a foundation for the prevention and control of such diseases.Methods:The Chinese version of the Musculoskeletal Disorders Electronic Questionnaire was used to conduct a nationwide survey on the prevalence of WMSDs in the upper extremity. Six factors related to WMSDs in the upper extremity were extracted by the classification standard of adverse ergonomic factors and their source and confirmatory factor analysis, including work organization, work type, upper extremity work posture, individual factors, upper extremity fatigue and upper extremity WMSDs. The structural equation analysis was carried out and the structural equation model was established.Results:The incidence of WMSDs and fatigue in the upper limbs was 24.44% and 43.76%, respectively. The adjusted structural equation model fitting indicators were generally up to the standard (GFI=1.000, AGFI=1.000, RMSEA=0.043, NFI=0.808, TLI=0.784) . The four exogenous latent variables of work organization, work type, upper limb work posture and individual factors were correlated. There was a strong positive correlation between job type and upper limb work posture ( r=0.865) , a moderate positive correlation between work organization and job type and upper limb work posture ( r=0.570, 0.490) , and a weak negative correlation between individual factors and the other three exogenous latent variables. Upper limb work posture and individual factors had direct effects on upper limb WMSDs, and the effect coefficients were 0.10 and 0.06, respectively. Upper limb fatigue played a mediating role between work organization, work type, upper limb work posture and upper limb WMSDs. The effect coefficient was 0.46, and the composition ratios of indirect effects were 100.0%, 100.0%, and 38.3%, respectively. The direct path effect of upper limb work posture, individual factors and upper limb WMSDs was weaker than the mediating path through upper limb fatigue. Conclusion:When carrying out the prevention and control of upper limbWMSDs, it is necessary to comprehensively consider the pathogenesis path of upper limb muscle fatigue and upper limb WMSDs caused by work organization, work type, and upper limb work posture, so as to provide theoretical reference for improving the prevention and control level of such diseases.

Ketosis is an energy metabolism disorder occurring frequently in periparturient dairy cows,primarily attributed to elevated non-esterified fatty acid(NEFA)levels resulting from nega-tive energy balance(NEB).Excessive NEFA will be incompletely oxidated into large amounts of ketone bodies or be re-esterified and deposit in the liver as a consequence of hepatic limited oxida-tive capacity,ultimately leading to ketosis and fatty liver.Hypoxic microenvironments are com-monly found during the progression of various liver diseases.Hypoxia inducible factor-2 alpha(HIF-2 alpha)has been identified as a crucial regulator of lipid metabolism.However,it is still un-clear the association between HIF-2α and disrupted lipid metabolism in the livers of in ketotic cows.This study aims to investigate the effect of high concentrations of NEFA on HIF-2α expres-sion and cellular oxygen homeostasis through bovine liver tissue and primary hepatocytes.In vivo,hepatic triglyceride(TAG)content was assessed to determine the extent of hepatic lipid accumula-tion,and HIF-2α protein and mRNA levels were analyzed by immunohistochemistry staining,Western blot and qRT-PCR assay in liver tissue samples from dairy cows;in vitro,bovine primary hepatocytes were treated with different concentrations of NEFA.Oil Red O staining and TAG con-tent assay were performed to determine hepatocellular steatosis extent,and immunofluorescence staining.Western blot,and qRT-PCR were performed to analyze HIF-2α expression,in addition,lu-minescent oxygen sensor[Ru(dpp)3]Cl2 was added to indicate intracellular oxygen levels.These results showed a significant increase in TAG content and elevated HIF-2α expression in the liver tissue of ketotic cows,and high concentrations of NEFA induced lipid accumulation,upregulation of HIF-2α expression,and intracellular hypoxia in bovine primary hepatocytes.These findings sug-gested that HIF-2α was significantly"activated"in the liver of ketotic cows and high concentration of NEFA-induced bovine primary hepatocytes,and that high concentrations of NEFA induced in-tracellular hypoxia in vitro.This study provides a potential molecular target for further investiga-tion of the mechanism underlying hepatic lipid metabolism disorders in ketotic cows.

Objective:To investigate and summarize the imaging and pathological features of non-acute occlusion following flow diverter (FD) implantation in animal models.Methods:Four experimental pigs (experimental group) that experienced non-acute occlusion (occlusion time exceeding 24 hours) within the FD stent implanted in the common carotid artery, and 19 pigs (control group) that did not experience stent occlusion during the same period were involved. Using an interventional approach under digital subtraction angiography (DSA), the 4 occluded FD lumens were mechanically opened. Optical coherence tomography (OCT), intravascular ultrasound (IVUS) and histopathological examinations were performed to evaluate the intraluminal composition and characteristics of the occlusive tissues. These findings were compared with non-occluded FD stents to summarize the imaging and pathological changes within the occluded FD lumen.Results:The occlusion times of the FD stents in the 4 experimental pigs were 16 weeks, 20 weeks, 20 weeks, and 24 weeks postoperatively. All occluded stents were successfully recanalized under DSA, with a technical success rate of 4/4. Among the 19 non-occluded FD stents, OCT and IVUS revealed uniform (16 stents) or non-uniform (3 stents) neointimal coverage of the stent struts, presenting as homogeneous high/slightly high signal intensity or medium echogenicity. Histopathological examination indicated that the neointima was primarily composed of smooth muscle cells and a small amount of fibrous connective tissues. In contrast, the 4 occluded FD stents demonstrated excessive neointimal proliferation and plaque formation, leading to luminal loss, as shown by OCT and IVUS. The occlusion tissues predominantly presented as homogeneous high signal intensity with weak attenuation (fibrous plaques) on OCT, with some regions showing blurred low signal intensity and strong attenuation (lipid plaques). IVUS presented homogeneous echogenicity (fibrous plaques) and hypoechogenic zones (lipid plaques). Histopathological examination showed that the occlusion tissues mainly consisted of smooth muscle cells, fibrous connective tissues, and lipids, accompanied by numerous foam cells and a minor presence of inflammatory cells.Conclusions:Histopathological examinations confirm that non-acute occlusion of FD is mainly caused by excessive hyperplasia of intima along with the formation of fibrous plaques and lipid plaques. OCT and IVUS have typical finding in imaging that can assist in determining the cause of stent occlusion as well as the lesion's nature, thereby providing crucial guidance for subsequent clinical treatment and drug selection.

Acute symptomatic osteoporotic thoracolumbar compression fracture (ASOTLF) can lead to chronic low back pain, kyphosis deformity, pulmonary dysfunction, loss of mobility, and even life-threatening complications. Vertebral augmentation is currently the mainstream treatment method for this condition. In 2019, the Editorial Board of Chinese Journal of Trauma and the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association collaboratively led the development of Clinical guideline for vertebral augmentation for acute symptomatic osteoporotic thoracolumbar compression fractures. Six years later, with advances in clinical diagnosis and treatment techniques as well as accumulating evidence in related fields, the 2019 guideline requires updating. To this end, the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association, the Spinal Health Professional Committee of China Human Health Science and Technology Promotion Association, and the Minimally Invasive Orthopedics Professional Committee of Shaanxi Medical Doctor Association have organized experts in the field to develop the Clinical guideline for vertebral augmentation of acute symptomatic osteoporotic thoracolumbar compression fractures ( version 2025) , based on the latest evidence-based medical researches. This guideline incorporates 3 recommendations retained from the 2019 version with updated strength of evidence, along with 12 new recommendations. It provides recommendations from six aspects of diagnosis, pain management, treatment option selection, prevention of postoperative complications, anti-osteoporosis therapy, and postoperative rehabilitation, aiming to provide a reference for standard treatment of vertebral augmentation for ASOTLF in hospitals at all levels.

ObjectiveTo investigate the target proteins directly bound by neochlorogenic acid (NA) and the molecular mechanisms that ameliorate the proliferation and inflammatory response of psoriatic keratinocytes. MethodsM5-induced HaCaT cells were used as a psoriatic keratinocyte proliferation and inflammatory cell model. The synthesized NA probe (NA-P) and NA prodrug were first evaluated for cell viability using a cell proliferation/cell counting kit-8(CCK-8). The potency of NA and NA-P was evaluated in the safe concentration range, and the effects of 0-100 μmol·L-1 NA and probe on M5-induced proliferation of HaCaT cells were detected using CCK-8. The effects of 20, 40, 80 μmol·L-1 NA and 80 μmol·L-1 NA-P on the expression of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), interleukin-23 (IL-23), and interleukin-17A (IL-17A) inflammatory factors were detected by enzyme-linked immunosorbent assay (ELISA), and real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to measure the effects of NA on the mRNA expression of keratin 16 (K16) in HaCaT cells, S100 calcium-binding protein A9 (S100A9), S100 calcium-binding protein A7 (S100A7), IL-6, IL-17A, and chemokine 1 (CXCL1). In vitro fluorescence labeling and competition experiments using NA-P were performed, and target protein angling and analysis using pull-down experiments combined with liquid chromatography-mass spectrometry (Pull-down/LC-MS/MS) were conducted. Target validation was performed using pull-down experiments combined with protein immunoblotting (Pull down-WB), cellular heat transfer analysis combined with protein immunoblot (CETSA-WB) experiments, and molecular docking. Finally, Real-time PCR was utilized to detect the effects of 20, 40, 80 μmol·L-1 NA and 80 μmol·L-1 NA-P on the mRNA expression of IL-1β, nucleotide-binding oligomeric structural domain-like receptor protein 3 (NLRP3), apoptosis-associated speckled-like protein (ASC), and cysteine protease-1 (Caspase-1) in HaCaT cells. Protein immunoblot (Western blot) was used to detect the effects of phosphorylated p65 (p-p65), p65, phosphorylated human nuclear factor-κB inhibitory protein α (p-IκBα), human nuclear factor κB inhibitory protein α (IκBα), and heat shock protein 90 (HSP90) expression. ResultsIn the 200 μmol·L-1 safe concentration range, HaCaT cell proliferation, increased expression of TNF-α, IL-1β, IL-23, and IL-17A inflammatory factors, and increased mRNA expression of K16, S100A9, S100A7, IL-6, IL-17A, and CXCL1 were observed in the M5 group compared with the blank group. Cell proliferation in 5-100 μmol·L-1 NA and NA-P groups was inhibited, and the expression of TNF-α, IL-1β, IL-23, and IL-17A inflammatory factors was decreased in the NA-L, NA-M, NA-H, and NA-P-H groups. The mRNA expression of K16, S100A9, S100A7, IL-6, IL-17A, and CXCL1 was decreased (P<0.05). High-confidence targets were screened for HSP90 protein by Pull-down/LC-MS/MS using 200 μmol·L-1 NA competing with 100 μmol·L-1 NA-P. Compared with that in the blank group, the mRNA expression of NLRP3, IL-1β, ASC, and Caspase-1, as well as the expression of p-p65/p65, p-IκBα/IκBα, and HSP90 protein, were increased in HaCaT cells in the M5 group (P<0.05). Compared with that in the M5 group, the mRNA expression of NLRP3, IL-1β, ASC, and Caspase-1 of cells in the NA-L group, the NA-M group, the NA-H group, and the NA-P-H group was decreased (P<0.05). p-p65/p65 and p-IκBα/IκBα were decreased in the NA-M and NA-H groups (P<0.05), and there was no change in HSP90 protein. Pull down-WB showed that NA could directly target HSP90 protein, and NA binding to HSP90 protein enhanced its thermal stability. Molecular docking of NA with HSP90 family proteins HSP90AA1, HSP90B1, and HSP90AB1 all resulted in highly stable binding. ConclusionNA can inhibit the proliferation and inflammatory response of psoriatic keratinocytes by a mechanism that may be achieved by targeting HSP90 to modulate the NF-κB/NLRP3 signaling pathway.
