The spine is the most common site of skeletal metastasis in lung cancer, which frequently leads to severe complications such as pathological fracture and neurological compromise and is associated with poor prognosis. The development and progression of spinal metastasis from lung cancer are linked to the unique local microenvironment and tumor microenvironment (TME) of the vertebral column. During metastatic evolution, the dense vascular network of the spine and a plethora of signaling molecules, together with the complex cellular constituents and their intricate interactions within the TME, all cooperate to facilitate the tumor invasion and colonization of the vertebral compartment. Mechanistic studies delineating the role of the TME in spinal metastasis from lung cancer have markedly expanded, fostering the emergence of innovative therapeutic strategies—including nanomedicines, sono-photodynamic therapy, gene therapy, and combination regimens. These strategies demonstrate remarkably potential for clinical translation and offer new directions for the precision management of spinal metastasis from lung cancer.

ObjectiveTo establish a narrative nursing program for patients with advanced liver cancer based on the framework of Snyder’s hope theory， and verify its effectiveness. MethodsThe Johns Hopkins evidence-based nursing model and the Delphi method were employed to construct the narrative nursing program for patients with advanced liver cancer. Utilizing the convenience sampling method， 70 patients with advanced liver cancer hospitalized in the department of hepatobiliary surgery from May 2024 to May 2025 were selected and divided into the control group and the intervention group using the random number table method， with 35 patients in each group. The control group received routine nursing care， while the intervention group received the narrative nursing program based on Snyder’s hope theory for patients with advanced liver cancer. The Herth Hope Index， Connor-Davidson Resilience Scale （CD-RISC）， Self-Rating Anxiety Scale （SAS）， and Morisky Medication Adherence Scale-8 （MMAS-8） were used to compare the hope level， psychological resilience， anxiety， and medication adherence between the two groups before and after the intervention. Furthermore， nursing satisfaction was also compared. ResultsThe Delphi expert consultation results demonstrated high consistency among expert opinions， with an expert positive coefficient of 100%. Meanwhile， the authority coefficients （0.902， 0.912） and Kendall’s concordance coefficients （0.260， 0.283） were all satisfactory. Ultimately， a narrative nursing program was established， consisting of 3 primary indicators， 10 secondary indicators， and 19 tertiary indicators. Compared with the control group， the intervention group exhibited significant improvements in scores of the three dimensions regarding the hope level， the total score of psychological resilience， medication adherence， and nursing satisfaction after the intervention， and the anxiety score was markedly reduced. All differences were statistically significant （P<0.05）. ConclusionThe narrative nursing program for patients with advanced liver cancer developed in this study is scientific and reliable. Its clinical application can effectively improve the psychological status and treatment behaviors of patients with advanced liver cancer， profoundly reflect the ethical care for the humanistic needs of patients， and provide an evidence-based basis for optimizing the psychological support for this population.

BACKGROUND: Delayed platelet engraftment is a common complication after umbilical cord blood transplantation (UCBT), and there is no standard therapy. Avatrombopag (AVA) is a second-generation thrombopoietin (TPO) receptor agonist (TPO-RA) that has shown efficacy in immune thrombocytopenia (ITP). However, few reports have focused on its efficacy in patients diagnosed with thrombocytopenia after allogeneic hematopoietic stem cell transplantation (allo-HSCT). METHODS: We conducted a retrospective study at the First Affiliated Hospital of the University of Science and Technology of China to evaluate the efficacy of AVA as a first-line TPO-RA in 65 patients after UCBT; these patients were compared with 118 historical controls. Response rates, platelet counts, megakaryocyte counts in bone marrow, bleeding events, adverse events and survival rates were evaluated in this study. Platelet reconstitution differences were compared between different medication groups. Multivariable analysis was used to explore the independent beneficial factors for platelet implantation. RESULTS: Fifty-two patients were given AVA within 30 days post-UCBT, and the treatment was continued for more than 7 days to promote platelet engraftment (AVA group); the other 13 patients were given AVA for secondary failure of platelet recovery (SFPR group). The median time to platelet engraftment was shorter in the AVA group than in the historical control group (32.5 days vs . 38.0 days, Z  = 2.095, P  = 0.036). Among the 52 patients in the AVA group, 46 achieved an overall response (OR) (88.5%), and the cumulative incidence of OR was 91.9%. Patients treated with AVA only had a greater 60-day cumulative incidence of platelet engraftment than patients treated with recombinant human thrombopoietin (rhTPO) only or rhTPO combined with AVA (95.2% vs . 84.5% vs . 80.6%, P  <0.001). Patients suffering from SFPR had a slightly better cumulative incidence of OR (100%, P  = 0.104). Patients who initiated AVA treatment within 14 days post-UCBT had a better 60-day cumulative incidence of platelet engraftment than did those who received AVA after 14 days post-UCBT (96.6% vs . 73.9%, P  = 0.003). CONCLUSION Compared with those in the historical control group, our results indicate that AVA could effectively promote platelet engraftment and recovery after UCBT, especially when used in the early period (≤14 days post-UCBT).

Objective To explore the serial mediating roles of physical functional impairment and cognitive function between chronic comorbidity and depression in older adults.Methods Based on 5773 older adults with at least one chronic disease from the 2020 China Health and Retirement Longitudinal Survey as study subjects,Spearman correlation analysis was used to explore the correlation between chronic comorbidities,physical functional impairment,cognitive function,and depression in older adults,and serial mediating effects were analyzed using the model 6 in Process 3.3 of SPSS.Results 4465 older adults(77.34%)had chronic comorbidities,and the direct effect of chronic comorbidities on depression in older adults was significant,with an effect size of 1.737(95%CI:1.373-2.101),the separate mediating effect of physical functional impairment was significant,with an effect size of 0.535(95%CI:0.432-0.642);the separate mediating effect of cognitive function was not significant,with an effect size of-0.037(95%CI:-0.086 to 0.011);the serial mediating effect of physical functional impairment and cognitive function was significant,with an effect size of 0.027(95%CI:0.018 to 0.037).Conclusion Chronic comorbidity promotes the development of depression in older adults and indirectly influences the development of depression through physical functional impairment and poorer cognitive function.Therefore,in order to avoid the onset or exacerbation of depression in older adults with chronic diseases,it is important to enhance the ability of this group to care for themselves in daily life as well as to promote the recovery of cognitive function,especially in older adults with chronic comorbidities.

Objective To explore the serial mediating roles of social participation and cognitive function in the relationship between internet use and depression in older adults.Methods Based on 6356 older adults from the 2020 China Health and Retirement Longitudinal Survey(CHARLS),the Process 3.3 of SPSS was employed to analyze the serial mediation effects.Results 1650 older adults(25.96％)had used the internet in the past month.The direct effect of internet use on depression was not significant,with an effect value of 0.088(95％CI:-0.282 to 0.458).The separate mediating effect of social participation was significant,with an effect value of-0.228(95％CI:-0.299 to-0.163).The separate mediating effect of cognitive function was also significant,with an effect value of-0.207(95％CI:-0.271 to-0.147).The serial mediation effect of social participation and cognitive function was significant,with an effect value of-0.027(95％CI:-0.038 to-0.017).Conclusion Internet use indirectly reduces or mitigates depression in older adults by promoting social participation and enhancing cognitive function.Therefore,efforts should be made to address the digital divide among older adults,encourage the internet use for recreational activities,facilitate social participation,and enhance cognitive function to prevent the onset or worsening of depression and to build a society conducive to active aging.

Objective To observe the value of artificial intelligence iterative reconstruction(AIIR)for abdominal and pelvic CT examination after total hip arthroplasty(THA).Methods Totally 64 patients after THA who underwent abdominal and pelvic CT examinations were retrospectively collected,including 31 patients received routine CT scanning and 33 patients received dual-energy CT scanning.AIIR and hybrid iterative reconstruction(HIR)algorithms were used to obtain AIIR and HIR images based on conventional CT images,respectively,while 70-140 keV(interval of 5 keV)virtual monoenergetic images(VMI)were reconstructed based on dual-energy CT images.VMI with the best comprehensive imaging qualities were selected for analysis.Subjective scores and objective evaluation results of imaging quality were compared among different kinds of images.Results The subjective scores of artifacts,bones,diagnostic confidence,as well as displaying of pelvic organs and blood vessels on both AIIR images and VMI were all higher than those of HIR images(all P＜0.001),while no significant difference was found between AIIR images and VMI(all P＞0.017).Pairwise comparison of high-density artifact fraction and skeletal artifact fraction on AIIR,HIR images and VMI showed significant differences(all P＜0.001).No significant difference of low density artifact fraction nor high density noise fraction was detected between AIIR image and VMI(both P＞0.017),and the objective evaluation results were different from those of HIR images(both P＜0.017).The low density noise fraction of AIIR images was lower than that of HIR images(P＜0.017),while no significant difference was found between AIIR or HIR images and VMI(both P＞0.017).The bone noise fraction of AIIR and HIR images were both higher than that of VMI(both P＜0.017),while no significant difference was found between these two kinds of images(P＞0.017).Conclusion AIIR could reduce artifacts and image noise of abdominal and pelvic CT examination after THA and improve imaging quality.

Objective:To investigate the occurrence of work-related musculoskeletal disorders (WMSDs) among underground coal mine workers, identify the risk factors for WMSDs, and provide a scientific evidence for the prevention and treatment of WMSDs.Methods:In March 2024, through cluster sampling, the on-the-job workers who underwent questionnaire surveys and health examinations at a certain coal mine from July to August 2018 were selected as the research subjects. Basic information of employees, ergonomics-related characteristics, and the occurrence status of WMSDs in each part were collected, and multivariate logistic regression was used for analysis.Results:The incidence rate of WMSDs in at least one site among underground coal mine workers within the past year was 62.22% (219/352). The top three sites in sequence were the lower back (44.32%, 156/352), neck (26.14%, 92/352), and knee (26.14%, 92/352). Multivariate logistic regression analysis showed that frequently exerting great force with arms or hands during work ( OR=2.223, 95% CI: 1.022-4.836), prolonged static forward bending ( OR=1.544, 95% CI: 1.305-1.972), and frequently exerting great effort to operate tools or machines ( OR=2.206, 95% CI: 1.011-4.813), absence of external support systems ( OR=1.589, 95% CI: 1.349-1.996), and repetitive full-body twisting ( OR=1.523, 95% CI: 1.298-1.916) were all risk factors for the occurrence of WMSDs in the lower back ( P<0.05). Both night shift work ( OR=1.564, 95% CI: 1.339-1.939) and frequent forward neck flexion ( OR=1.532, 95% CI: 1.312-1.907) were all risk factors for the occurrence of WMSDs in the neck ( P<0.05). Lifting heavy objects above the shoulder ( OR=1.333, 95% CI: 1.142-1.782), uncomfortable posture and inability to exert force ( OR=1.873, 95% CI: 1.104-2.712), the use of vibration tools ( OR=2.958, 95% CI: 1.255-6.972), and length of service >10 years ( OR=1.525, 95% CI: 1.105-1.967) were all risk factors for the occurrence of WMSDs in the knee ( P<0.05) . Conclusion:The incidence of WMSDs among underground coal miners is relatively high, mainly concentrated in the lower back, neck and knee, and is related to factors such as poor working postures, and work organization. Coal mining enterprises should strengthen work organization, provide appropriate working equipment, and ensure reasonable distribution of workloads.

Objective:To identify risk factors influencing the incidence of hypertension among steelworkers (Homo sapiens) and establish an effective and easily implementable hypertension prediction model.Methods:In September 2023, 2214 steelworkers (Homo sapiens) were selected as study subjects. Basic demographic information, lifestyle, and occupational exposure data were collected, along with physiological measurements such as height, weight, and blood pressure. Multivariate unconditional logistic regression analysis was employed based on relevant literature to determine influencing factors for hypertension among steelworkers (Homo sapiens). Python 3.9 software was used to construct and compare logistic regression, support vector machine (SVM), random forest, extreme gradient boosting tree (XGBoost), and LGBM models. Model performance was evaluated using metrics such as receiver operating characteristic (ROC) curves, accuracy, calibration curves, and F1 scores. The Shapley Additive Explanations (SHAP) model was introduced for feature importance analysis to enhance the interpretability of the prediction model.Results:A total of 432 cases of hypertension were detected among 2214 study subjects, with a detection rate of 19.51%. Age, smoking status, salt intake, use of cooling equipment, carbon monoxide exposure, family history of hypertension, fasting blood glucose, triglycerides, and hemoglobin were identified as independent risk factors for hypertension ( P<0.05). A comparison of the five models revealed the following performance metrics: logistic regression achieved an accuracy of 0.853, F1 score of 0.680, Brier score of 0.108, and AUC of 0.907; SVM demonstrated an accuracy of 0.863, F1 score of 0.687, Brier score of 0.081, and AUC of 0.910; random forest showed an accuracy of 0.857, F1 score of 0.603, Brier score of 0.105, and AUC of 0.861; XGBoost yielded an accuracy of 0.850, F1 score of 0.684, Brier score of 0.117, and AUC of 0.899; and the LGBM model exhibited an accuracy of 0.838, F1 score of 0.625, Brier score of 0.112, and AUC of 0.870. Conclusion:The SVM model demonstrated strong predictive performance, effectively assessing the risk of hypertension among steelworkers (Homo sapiens) and facilitating targeted health management interventions.

Objective To compare the safety and efficacy of vancomycin in obese patients guided by trough concentration and AUC24h/MIC,and to provide data for individualized administration of vancomycin in obese patients.Methods We retrospectively collected the data of obese adult patients(BMI 30 kg/m2)who had severe infection caused by gram-positive cocci and treated with vancomycin intravenously in two Grade A tertiary hospitals in Shanghai from 2012 to 2024.The patients were assigned to trough concentration monitoring group or AUC24h/MIC monitoring group according to the therapeutic drug monitoring(TDM)method at the time of admission.Nephrotoxicity and efficacy were compared between the two groups of patients.Results A total of 22 obese patients were included in this study,including 12 in the trough concentration monitoring group and 10 in the AUC24h/MIC monitoring group.No significant difference was found between the two groups in gender,age,BMI,creatinine clearance before treatment,underlying disease,site of infection,pathogen type,or concomitant medications.The proportion of ICU admission was higher in AUC24h/MIC monitoring group.The length of ICU stay,vancomycin treatment duration,bacterial clearance rate and comprehensive efficacy rate did not show significant difference between the two groups.The average daily dose of vancomycin in trough concentration monitoring group was significantly lower than that in A UC24h/MIC monitoring group[(1.63±0.59)g vs(2.29±0.72)g,P=0.026].The average treatment duration was not significantly different between the two groups[(15.33±10.28)d vs(14.90±6.92)d,P=0.911].Compared with the trough concentration monitoring group,the initial peak concentration[(30.99±16.22)mg/L vs(19.41±5.42)mg/L,P=0.025]and overall peak concentration[(33.67±16.53)mg/L vs(22.08±3.96)mg/L,P=0.045]of vancomycin were lower in theAUC24h/MIC monitoring group,but the initial trough concentration[(11.03±8.66)mg/L vs(6.33±4.45)mg/L,P=0.139]and overall trough concentration[(13.75±9.74)mg/L vs(9.74±4.24)mg/L,P=0.218]were similar in the two groups.Vancomycin-associated nephrotoxicity did not occur in any group,but 41.7％of the patients in the trough concentration monitoring group reached the threshold of renal toxicity,i.e.trough concentration ≥15 mg/L.Conclusions Vancomycin treatment with conventional dosing regimen still have good clinical efficacy in obese adult patients.Vancomycin therapy guided by A UC24h/MIC can achieve the target value at lower concentration or exposure,which is promising for reducing vancomycin-associated nephrotoxicity.
