The imaging features of intracranial melanoma are similar to those of other intracranial tumors, and a definite diagnosis often cannot be made solely based on imaging examinations. Although molecular pathology can detect gene mutations and protein markers of intracranial melanoma, its diagnostic specificity is limited due to the cross-expression of markers. Studies have shown that the combined application of imaging and molecular pathology can obviously improve the diagnosis sensitivity and specificity of intracranial melanoma, and by integrating the morphological and molecular characteristics of the melanoma, this combined application can optimize individualized treatment strategies and play important roles in surgical planning, targeted therapy selection, and therapeutic efficacy detection. This article reviews the research progress on the synergistic role of imaging and molecular pathology in the diagnosis and targeted therapy of intracranial melanoma, with the aim of providing a reference for diagnosis and treatment of intracranial melanoma.

Objective To investigate the safety of endoscopic inflatable thyroid surgery on elderly patients by comparing the clinical characteristics and incidence of postoperative complications between elderly and non-elderly patients.Methods A retrospective analysis of clinical data was conducted on 204 patients who underwent endoscopic inflatable thyroid surgery at The Second Affiliated Hospital of Xi'an Jiaotong University from May 2021 to August 2024.Based on propensity score matching(PSM),a total of 54 elderly patients(age ≥60 years)and 150 middle-aged and young patients(18-59 years)were selected for comparison of clinical data,surgical-related indicators,and postoperative outcomes between the two groups.Results After matching,baseline data in both groups exhibited no statistically significant differences(P＞0.05).There were no statistically significant variances(P＞0.05)in intraoperative blood loss,surgical time,postoperative drainage volume,Faces Pain Scale-Revised(FPS-R),hoarseness,or hypoparathyroidism between the two groups.Although the two groups differed significantly in the Charlson Comorbidity Index(CCI)and age-adjusted Charlson Comorbidity Index(aCCI)(P＜0.05),there were no significant differences in the postoperative delirium,acute cardiocerebrovascular events,hospitalization costs,or postoperative length of stay(P＞0.05).One patient in the elderly group had postoperative delirium and but recovered 5 days after surgery.Conclusion Although elderly patients have more chronic complications than non-elderly,endoscopic thyroid surgery in elderly patients with thyroid tumors remains safe and effective,which makes it deserve clinical application.

Objective:To explore the value of the vesical imaging-reporting and data system (VI-RADS) score based on multiparametric MRI (mpMRI) combined with quantitative tumor MRI parameters in assessing the muscle invasion of bladder cancer.Methods:The study was a case-control study. The data of 87 bladder cancer patients confirmed by pathology who underwent mpMRI of the bladder were retrospectively collected from the First Medical Center of Chinese PLA General Hospital between January 2019 and April 2023 The pathological findings were used as the gold standard to categorize them into the muscle invasive bladder cancer (MIBC) group (29 cases) and non-muscle invasive bladder cancer (NMIBC) group (58 cases). Quantitative parameters were measured based on preoperative mpMRI images, including the length of tumor bladder wall contact, the perpendicular distance between the bladder tumor and the tangent of the bladder wall, the maximal diameter of the bladder tumor, and the volume of the bladder tumor. Bladder cancer was classified according to the VI-RADS scoring criteria. The Mann-Whitney U test was used for intergroup comparisons. Multivariate logistic regression analysis was performed to obtain the independent risk factors related to muscle invasion of bladder cancer and to establish the model. The receiver operating characteristic curves were analyzed for MRI quantitative parameters and logistic regression models, and area under the curve (AUC) comparisons were performed using the DeLong test. Results:The differences in tumor bladder wall contact length, perpendicular distance from the tumor to the tangent line of the bladder wall, maximum diameter, bladder tumor volume, and the VI-RADS scores were statistically significant between the MIBC group and the NMIBC group ( P<0.05). Multifactorial logistic regression analysis showed that tumor bladder wall contact length ( OR=21.07, 95% CI 3.56-124.89, P=0.001) and VI-RADS score ( OR=11.90, 95% CI 3.53-40.12, P<0.001) were the independent risk factors for evaluating the muscle invasion of bladder cancer. The difference between the VI-RADS score and the tumor bladder wall contact length for assessing muscular infiltration of bladder cancer had AUCs of 0.802 (95% CI 0.704-0.899) and 0.759 (95% CI 0.652-0.865). The combined model of VI-RADS score combined with tumor bladder wall contact length had an AUC of 0.891 (95% CI 0.812-0.970), which was higher than the diagnostic efficacy of applying tumor bladder wall contact length or VI-RADS score alone ( Z=3.05, 2.37, P=0.002, 0.018). Conclusion:Tumor contact length with the bladder wall is an independent risk factor for assessing muscle invasion of bladder cancer and the combination of VI-RADS score may enhances diagnostic accuracy.

Objective:To analyze the association between daily physical activity patterns and dyslipidemia among people receiving physical examination aged 40-65 years.Methods:This cross-sectional study consecutively enrolled 864 participants aged 40-65 years and met the inclusion and exclusion criteria who underwent health check-ups at the Physical Examination Center of Fuquan First People′s Hospital from March to November in 2022. The data of general characteristics, physical activity, physical examination findings, and lipid profiles were collected. The daily physical activity patterns were identified using K-means clustering analysis. The unconditional binary logistic regression was employed to explore the associations between these activity patterns and dyslipidemia, followed by subgroup analyses.Results:The physical activity of the 864 study participants (517 males and 347 females) included in the analysis was divided into 4 patterns (G1: low physical activity; G2: active commuting; G3: housework; G4: leisure exercise). Using G1 as a reference, after adjusting for confounders, G4 was negatively associated with low high density lipoprotein cholesterol (HDL-C) ( OR=0.37, 95% CI: 0.14-1.00) ( P=0.05). In the male, G3 was negatively associated with dyslipidemia ( OR=0.44, 95% CI: 0.21-0.93) and low HDL-C ( OR=0.25, 95% CI: 0.10-0.68) (both P<0.05). In the subjects aged 50 years and above, G2 was negatively associated with dyslipidemia ( OR=0.52, 95% CI: 0.30-0.90), hypertriglyceridemia ( OR=0.50, 95% CI: 0.28-0.90) and low HDL-C ( OR=0.47, 95% CI: 0.24-0.91) (all P<0.05). In those who never or occasionally stayed up late, G2 was negatively associated with hypertriglyceridemia ( OR=0.31, 95% CI: 0.13-0.75) ( P<0.05); in those who stayed up late often, G4 was negatively associated with dyslipidemia ( OR=0.33, 95% CI: 0.13-0.85) and low HDL-C ( OR=0.19, 95% CI: 0.04-0.84) (both P<0.05). In the centrally obese population, G2 was negatively associated with dyslipidemia ( OR=0.55, 95% CI: 0.35-0.88) and hypertriglyceridemia ( OR=0.54, 95% CI: 0.33-0.86) (both P<0.05). Conclusions:Association between different physical activity patterns and dyslipidemia varied among adults aged 40-65 years undergoing health check-ups. Leisure-time exercise is associated with a reduced risk of dyslipidemia, while household activities also emerges as a beneficial factor linked to lower dyslipidemia risk particularly in the male population.

Objective To investigate the entrance surface dose (ESD) of dental radiological diagnosis and treatment devices in Nanping City of Fujian Province, China, assess the radiation risk differences between cone beam computed tomography (CBCT) and conventional oral panoramic tomography (COPT), and compare the output dose levels between domestic and imported devices and between public and private medical institutions, and to provide evidence for optimizing radiation protection strategies. Methods A cross-sectional survey was conducted on 38 extraoral dental X-ray devices from 38 dental institutions in Nanping City. Measurements of ESD for different exposure types (adult/child COPT and CBCT) were performed using an adult head-and-neck phantom and thermoluminescent dosimeters. A statistical analysis (Mann-Whitney U test) was applied to compare dose differences by device type and institution type. Results The median tooth-region doses for adult/child CBCT (8.97/6.80 mGy) were significantly higher than those of adult/child COPT (0.33/0.24 mGy), with the 75th percentile values (12.44/8.18 mGy) exceeding the national guideline level of 7 mGy. Domestically manufactured devices demonstrated higher median doses and greater dose variability compared to imported devices (P < 0.05). Private institutions exhibited inferior dose control stability relative to public institutions (P < 0.001). CBCT delivered substantially higher radiation exposure to the thyroid and ocular lenses, with child lens dose reaching 5.9 times that of COPT. Conclusion Dental CBCT radiation doses in Nanping City exceed the guideline level. Enhanced protection for sensitive organs, restriction of unnecessary pediatric examinations, technological upgrades for domestic devices, and strengthened regulation and operational standardization of private institutions are critical to achieve precise radiation protection and improved medical quality.

Objective:To evaluate the safety and effectiveness of robot-assisted coronary artery bypass(RACAB).Methods:We retrospectively analyzed the clinical outcomes from 252 consecutive patients who underwent RACAB in our center between April 2021 and August 2023. The internal mammary artery(IMA) was harvested using the skeletonized technique with the assistance of the robotic system. Then, graft-to-target vessel anastomoses were performed via a 4-6 cm left fifth intercostal thoracotomy. Coronary angiography or coronary CTA was routinely performed before discharge.Results:149 patients(59.1%) underwent multi-vessel coronary bypass. 140 patients(55.6%) underwent total arterial bypass grafting, with 131 patients(52.0%) undergoing RACAB with in situ bilateral IMA. IMA harvesting failed in 6 patients(1.6%). One patient(0.4%) was assisted by extracorporeal circulation, and 5 patients(2.0%) underwent re-thoracotomy postoperatively. The patency rate of grafts was 96.6%(449/465). The 12-month and 24-month survival rate were 97.8% and 96.5% respectively; The 12-month and 24-month MACCE-free survival rate were 95.2% and 92.6%, respectively.Conclusion:RACAB is safe and feasible. With the assistance of the robotic system, in situ bilateral IMA can be obtained and bypassed to all target vessels territory. Extended follow-up is warranted.

Objective:To elucidate the effects of different morphologies and sizes of micro/nanomaterial on luminescence properties.Methods:Lu2O3:Eu3+micro-/nanocrystals with different morphologies were synthesized hydrothermally,and the effects of precursor concentration,reaction time,pH,and alkali source on morphology and photoluminescence were investigated.Products were calcined and then characterized for morphology and photoluminescence.Spectra were collected with 250 nm excitation,focusing on the O2-→Eu3+charge-transfer band(CTB)and Eu3+f-f transitions.Results:The use of NaOH,aqueous ammonia,or triethylamine yielded monodisperse square nanosheets after calcination,while the use of urea produced monodisperse and uniform nanospheres.Fluorescence measurements showed a strong CTB near 250 nm.Under 250 nm excitation,the emission comprised multiple peaks,with the the strongest being the 5D?→7F2 hypersensitive transition at 614 nm.Conclusions:In the hydrothermal system,alkali source and reaction parameters provide significant control over the morphology and size of Lu2O3:Eu3+micro-/nanocrystals.The morphology-dependent emission is dominated by red light at 614 nm(5D?→7F).
