Rationale: Intrathoracic paragangliomas are typically found within the intricate posterior mediastinal region adjacent to the vertebrae, often presenting with substantial volume. Surgical excision of such tumors presents formidable challenges and is conventionally performed via open surgical procedures.

Patient Concerns: In this report, we present the case of a 53-year-old female patient who presented with the discovery of a left intrathoracic mass during a routine physical examination approximately 1 month prior.

Primary Pulmonary Meningioma With Associated Multiple Micronodules: A Case Report With Comprehensive Diagnostic Overview.

Background: Primary pulmonary meningioma (PPM) is an exceedingly rare neoplasm originating in the meninges within the lung. Despite sharing similarities with its central nervous system (CNS) counterparts, PPM presents unique diagnostic challenges and therapeutic considerations owing to its infrequent occurrence.

Case: This case report describes a 73-year-old male who underwent chest computed tomography (CT), which revealed a mass in the posterior basal segment of the right lower lobe, suggestive of a low-grade malignant tumor approximately 30-40 mm in size.

The interaction between DNA methylation and tumor immune microenvironment: from the laboratory to clinical applications.

DNA methylation is a pivotal epigenetic modification that affects gene expression. Tumor immune microenvironment (TIME) comprises diverse immune cells and stromal components, creating a complex landscape that can either promote or inhibit tumor progression. In the TIME, DNA methylation has been shown to play a critical role in influencing immune cell function and tumor immune evasion.

CircRNA hsa_circ_0000043 acts as a miR-4492 sponge to promote lung cancer progression via BDNF and STAT3 expression regulation in anti-benzo[a]pyrene-trans-7,8-dihydrodiol-9,10-epoxide-transformed 16HBE cells.

Increasing evidence shows that circular RNA (circRNA) plays an important role in the progression of lung cancer. In this study, we found that has_circ_0000043 was highly expressed in 16HBE-T human bronchial epithelial cells that were malignantly transformed by benzo[a]pyrene-trans-7,8-diol-9,10-epoxide via circRNA microarray. We verified that hsa_circ_0000043 was also significantly overexpressed in lung cancer cell lines and tissues.

Development and validation of a pulmonary complications prediction model based on the Yang's index.

Identification of and as Key Genes in Smoking-Related Non-Small-Cell Lung Cancer Through Bioinformatics and Functional Analyses.

Background: Lung cancer is the leading cause of cancer-related mortality worldwide. Although cigarette smoking is an established risk factor for lung cancer, few reliable smoking-related biomarkers for non-small-cell lung cancer (NSCLC) are available. An improved understanding of these biomarkers would further the development of new biomarker-targeted therapies and lead to improvements in overall patient survival.

Comprehensive landscape and interference of clonal haematopoiesis mutations for liquid biopsy: A Chinese pan-cancer cohort.

Tumour-derived DNA found in the plasma of cancer patients provides the probability to detect somatic mutations from circulating cell-free DNA (cfDNA) in plasma samples. However, clonal hematopoiesis (CH) mutations affect the accuracy of liquid biopsy for cancer diagnosis and treatment. Here, we integrated landscape of CH mutations in 11,725 pan-cancer patients of Chinese and explored effects of CH on liquid biopsies in real-world.

A genome-wide screen for differentially methylated long noncoding RNAs identified that lncAC007255.8 is regulated by promoter DNA methylation in Beas-2B cells malignantly transformed by NNK.

Tobacco exposure is well known to induce genetic and epigenetic changes that contribute to the pathogenesis of lung cancer. 4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) is a significant tobacco-specific carcinogen, but the oncogenic mechanisms of NNK have not been thoroughly elucidated. In this study we found that DNA methyltransferase 1 (DNMT1) was overexpressed in malignantly transformed human bronchial epithelial Beas-2B cells induced by NNK (2B-NNK cells), by treatment with NNK (400 μg/mL) for 7 days.

[Value of preoperative localization techniques for solitary pulmonary nodules in singleport thoracoscopic surgery].

To evaluate the value and clinical effect of different preoperative localization techniques for solitary pulmonary nodules (SPN) before single-port thoracoscopic surgery.From January 2018 to June 2019, 54 patients diagnosed with solitary pulmonary nodules received single-port thoracoscopic surgery in Thoracic Department of General Hospital of Southern Theater Command of PLA. Based on the location methods of the nodules, the patients were divided into group A (34 cases) with preoperative CT-guided Hook-wire (a common positioning needle usually using in mammary gland) positioning and group B (20 cases) with preoperative CT-guided methylene blue location.

The ideal methods for the management of rib fractures.

The clinical treatment choices for multiple rib fractures and flail chest are controversial. For example, among conservative treatment and surgical treatment, different studies have different conclusions and recommendations. Furthermore, early clinical research was mainly focused on the treatment of flail chest due to its severity.

Silencing of lncRNA AFAP1-AS1 suppressed lung cancer development by regulatory mechanism in and .

Although the long noncoding RNA AFAP1-AS1 has been shown to be involved in various types of cancer, its involvement in lung cancer remains poorly understood. In the current study, we found that AFAP1-AS1 was substantially over expressed in lung cancer tissues and cell lines. In addition, AFAP1-AS1 expression level was proven to be associated with the malignant features of lung cancer.

Biomarkers for early diagnosis, prognosis, prediction, and recurrence monitoring of non-small cell lung cancer.

Despite advances in the management of non-small cell lung cancer, it remains to be the leading cause of cancer-related deaths worldwide primarily because of diagnosis at a late stage with an overall 5-year survival rate of 17%. A reduction in mortality was achieved by low-dose computed tomography screening of high-risk patients. However, the benefit was later challenged by the high false positive rate, resulting in unnecessary follow-ups, thus entailing a burden on both the health care system and the individual.

Functional role of lncRNA DB327252 in lung cancer.

Background: Lung cancer becomes a concerning health issue and is considered one of the most deadly cancers in the worldwide. Most recently, long non-coding RNAs (lncRNAs) are newfound non-coding RNAs that are thought as one of the major players in a range of biological processes of human diseases. Although lncRNAs are involved in numerous cancer types, the precise understandings of lncRNAs' functional roles and mechanisms in lung cancer are limited.

A phosphoproteomic study reveals shp-1 cleavage reprograms LPS signaling via a PI-3K/NF-κB and mTORC1 related mechanism.

The reprogrammed lipopolysaccharide (LPS) pathway has been reported to render patients more susceptible to the development of post-traumatic multiple organ dysfunction syndrome (MODS). To facilitate thorough understanding of this mechanism, a phosphoproteomic study was utilized to screen the potential signaling molecules. Interestingly, a truncated form of Src homology 2-domain-containing tyrosine phosphatase 1 (shp-1) emerged in human THP-1 macrophages sequentially treated with H2O2 and LPS and not with either of the treatments alone.
