This review described the potential health threats to the cardiovascular system from micro-nano plastics (MNPs) and their multifaceted toxicity mechanisms. The article reviewed the environmental distribution of MNPs, exposure pathways, and their toxic effects on the cardiovascular system, and summarized the specific mechanisms of MNPs involving oxidative stress, inflammatory response, mitochondrial damage, apoptosis, pyroptosis, and autophagy dysregulation. Meanwhile, the combined toxic effects of MNPs with other environmental pollutants (e.g., heavy metals and polycyclic aromatic hydrocarbons), including synergistic, antagonistic, and dual effects, were analyzed, and the potential risks of MNPs as carriers of microorganisms and toxic chemicals were pointed out. The widespread presence of MNPs and their complex toxicity mechanisms may make them important triggers for cardiovascular diseases, but current research still suffers from unbalanced studies across environmental systems, incomplete understanding of plastic properties, and limited knowledge of long-term biological effects. Future research should focus on the long-term effects of MNPs, the joint toxicity mechanisms with other pollutants, and the differential effects across population subgroups. It is suggested to accelerate plastic recycling technology innovation, promote biodegradable materials, and optimize waste treatment process to mitigate the potential threat of MNPs pollution to human health. Through multidisciplinary collaboration and in-depth research, combining innovative concepts from toxicology, public health policy, and environmental science, it is expected to provide new methods and approaches for the prevention and treatment of cardiovascular diseases associated with MNPs.

Objective:To explore the impact of the fear of disease progression on the return-to-work readiness of patients after percutaneous coronary intervention (PCI) , and the chain mediating effect of psychological consistency and disease acceptance between the two factors.Methods:A convenience sampling method was used to select 198 PCI patients at the Affiliated Hospital of Jining Medical University from February 2023 to May 2024. The General Information Survey, Return-To-Work Readiness Scale, Fear of Progression Questionnaire-Short Form, Acceptance Illness Scale, and Sense of Coherence-13 were used to investigate the patients.Results:A total of 198 questionnaires were distributed, with 178 valid questionnaires returned, yielding an effective response rate of 89.90%. Among the patients' return-to-work readiness, 42 patients were in the pre-intention stage, 60 patients in the intention stage, 36 patients in the action preparation-self-assessment stage, and 40 patients in the action preparation-behavior stage. The fear of disease progression significantly influenced the patients' return-to-work readiness. Psychological consistency and disease acceptance played significant chain mediation roles between the fear of disease progression and return-to-work readiness, with a total mediation effect value of -0.072, accounting for 41.38% of the total effect.Conclusions:Return-to-work readiness in PCI patients needs improvement. Psychological consistency and disease acceptance play a chain mediation role between the fear of disease progression and return-to-work readiness. Healthcare providers should develop personalized care strategies based on patients' specific conditions, improve their psychological state, and enhance their readiness to return to work.

Objective:To analyze the clinicopathological features and differential diagnosis of large B-cell lymphoma with IRF4 rearrangement, aiming enhance its recognition and prevent misdiagnosis.Methods:The clinicopathological features, immunophenotype, and fluorescence in situ hybridization (FISH) results of six cases diagnosed with IRF4 rearrangement-positive B-cell lymphoma at the Affiliated Hospital of Xuzhou Medical University from 2015 to 2023 were retrospectively analyzed. Additionally, a comprehensive review of the literature was conducted.Results:Six patients with IRF4 rearrangement-positive large B-cell lymphoma were included. Patients 1 to 5 included three males and two females with a median age of 19 years ranging from 11 to 34 years. Four patients presented with head and neck lesions, while the other one had a breast nodule; all were in clinical Ann Arbor stages I to Ⅱ. Morphologically, entirely diffuse pattern was present in two cases, purely follicular pattern in one case, and diffuse and follicular patterns in other two cases. The tumor cells, predominantly centroblasts mixed with some irregular centrocytes, were of medium to large size, with a starry sky appearance observed in two cases. Immunophenotyping revealed all cases were positive for bcl-6 and MUM1, with a Ki-67 index ranging from 70% to 90%, and CD10 was positive in two cases. IRF4 rearrangement was confirmed in all cases by FISH analysis, with dual IRF4/bcl-6 rearrangements identified in two cases, leading to a diagnosis of LBCL-IRF4. Case 6, a 39-year-old female with a tonsillar mass and classified as clinical Ann Arbor stage Ⅳ, displayed predominantly diffuse large B-cell lymphoma (DLBCL) morphology with 20% high-grade follicular lymphoma characteristics. Immunohistochemistry showed negative CD10 and positive bcl-6/MUM1, with a Ki-67 index of approximately 80%. Triple rearrangements of IRF4/bcl-2/bcl-6 were identified by FISH, leading to a diagnosis of DLBCL with 20% follicular lymphoma (FL). All six patients achieved complete remission after treatment, with no progression or relapse during a follow-up period of 31-100 months.Conclusions:Large B-cell lymphoma with IRF4 rearrangement is a rare entity with pathological features that overlap with those of FL and DLBCL. While IRF4 rearrangement is necessary for diagnosing LBCL-IRF4, it is not specific and requires differentiation from other aggressive B-cell lymphomas with IRF4 rearrangement.

Objective To evaluate the safety and application value of stripping operation for the treatment of liver cavernous hemangioma. Methods Clinical data of 56 patients with liver cavernous hemangioma who underwent stripping operation in Hepatic Surgery Center, Tongji Hospital, Tongji Medical college, Huazhong University of Science and Technology from May 2008 to May 2012 were analyzed retrospectively. There were 21 males and 35 females with age ranging from 23 to 65 years old and the median age of 44 years old. The informed consents of all patients were obtained and the ethical committee approval was received. The patients received combined intravenous and endotracheal anesthesia. Occluding stripes were preset at the first porta and infrahepatic inferior vena cava, and the proper hepatic artery was dissected and clamped. Liver cavernous hemangioma was sharply dissected along its surface when the tumor got soft and shrunken. And the vessels in and out of the tumor were ligated. Pringle maneuver and infrahepatic inferior vena cava interruption (interruption length: 5-15 min) were performed in case of uncontrolled bleeding during the stripping operation. Results All the liver cavernous hemangiomas were enucleated successfully. The mean intraoperative blood loss of the patients was (437±135)ml, and no case received blood transfusion. Rupture of right hepatic vein was observed in 4 cases and rupture of middle hepatic vein in 2 cases during the operations, and they were successfully repaired with Prolene sutures. No death was observed during the perioperative period. Right-sided pleural effusion and peritoneal effusion were observed in 7 cases and bile leakage at the cut surface of liver in 1 case after the operations, and all were cured by drainage and symptomatic treatment. Conclusion Stripping operation is a safe and effective surgical procedure for liver cavernous hemangioma.

BACKGROUND AND OBJECTIVEIt has been proven that telomerase activation correlates with the carcinogenesis, aggressiveness and turnover of lung cancer. Telomerase is one of the improtant molecular biomarkers for diagnosis and targeting therapy in lung cancer. The aim of this study is to investigate the diagnostic value of the combined determination of telomerase activity in induced sputum, pleural effusion and fiberobronchoscopic biopsy in lung cancer patients.
METHODSThe technique of TRAP (telomeric repeat amplification protocal)-PCR-ELISA was employed to detect telomease levels of induced sputum, pleural effusion and fiberobronchoscopic biopsy in 80 lung cancer patients with pleural effusion and 50 benign pulmonary disease patients with pleural effusion.
RESULTSTelomemse levels of induced sputum, pleural effusion and fiberobronchoscopic biopsy were all significantly higher in patients with lung cancer than those with benign pulmonary disease (P < 0.001). There was no significant difference in the level of telomerase activity between different pathologic types (P > 0.05). The sensitivity of induced sputum, pleural effusion and fiberobronchoscopic biopsy were 62.5% (50/80), 46.3% (37/80) and 60.0% (48/80), respectively. The specificity were 72.0% (36/50), 66.0% (33/50) and 70.0% (35/50), respectively. The overall accuracy were 66.2% (86/130), 53.8% (70/130) and 63.8% (83/130), respectively. The sensitivity, specificity and overall accuracy of combined induced sputum, pleural effusion and fiberobronchoscopic biopsy were 85.0% (68/80), 78.0% (39/50) and 82.3% (107/130), respectively. The sensitivity of telomease level in combined detection for diagnosis of lung cancer was much higher than that in single sample detection (P < 0.01).
CONCLUSIONThe sensitivity of telomease activity in combined three samples was the highest. It can further improve the accuracy for the diagnosis of lung cancer with pleural effusion.
