Minimally invasive thoracoscopic resection of a micronodular thymoma with lymphoid stroma via a subxiphoid single-incision approach: A case report.

Rationale: This study aims to present a novel surgical approach for the resection of anterior mediastinal tumors, specifically focusing on micronodular thymoma with lymphoid stroma (MNT), a rare and distinct variant of thymoma. The single subxiphoid incision technique, although reported in limited cases, offers a minimally invasive option with potential benefits. We report the case of a 76-year-old male who underwent this innovative procedure and was diagnosed with MNT, providing insight into the management and outcomes of this rare pathology.

Scapular dislocation following radical surgical excision of lung sarcomatoid carcinoma: A rare case report.

Rationale: Scapular prolapse is a rare complication of thoracotomy. Only a few cases of scapular prolapse after thoracotomy have been reported. Here, we report the case of a 52-year-old male patient who underwent standard posterior thoracotomy for lung sarcomatoid carcinoma invading the left upper chest wall.

Localization diagnosis of adrenocorticotrophic hormone-dependent Cushing's syndrome: two case reports and literature review.

Background: The common causes of adrenocorticotrophic hormone (ACTH)-dependent Cushing's syndrome (CS) include Cushing's disease (CD) and ectopic ACTH syndrome (EAS). The differential diagnosis and lesion location of CD and EAS often bring great difficulties to clinical diagnosis and treatment. This article reports the localization diagnosis, treatment, and follow-up results of two patients with ACTH-dependent CS with different causes and reviews the literature.

Clinical utility of cryptococcal antigen detection in transthoracic needle aspirate by lateral flow assay for diagnosing non-HIV pulmonary cryptococcosis: A multicenter retrospective study.

Lateral flow immunoassay (LFA) detection of cryptococcal capsular polysaccharide antigen (CrAg) is reported to be the most rapid and convenient laboratory method for diagnosing cryptococcosis. Its clinical diagnostic use, however, is not well studied. We retrospectively analyzed the data from 97 patients with suspected pulmonary cryptococcosis (PC) at 2 tertiary care centers.

Connexin 43 overexpression induces lung cancer angiogenesis following phosphorylation at Ser279 in its C-terminus.

Blocking angiogenesis can inhibit tumor growth and metastasis. However, the mechanism underlying regulation of lung cancer angiogenesis remains unclear. The gap junction protein connexin 43 (Cx43) is implicated in angiogenesis.

PM2.5 promotes NSCLC carcinogenesis through translationally and transcriptionally activating DLAT-mediated glycolysis reprograming.

Background: Airborne fine particulate matter (PM2.5) has been associated with lung cancer development and progression in never smokers. However, the molecular mechanisms underlying PM2.

Connexins and angiogenesis: Functional aspects, pathogenesis, and emerging therapies (Review).

Connexins (Cxs) play key roles in cellular communication. By facilitating metabolite exchange or interfering with distinct signaling pathways, Cxs affect cell homeostasis, proliferation, and differentiation. Variations in the activity and expression of Cxs have been linked to numerous clinical conditions including carcinomas, cardiac disorders, and wound healing.

Successful resolution of ectopic Cushing syndrome by minimally invasive thoracoscopic resection of the neuroendocrine tumor of the thymus: a rare case report.

Background: Ectopic Cushing syndrome (ECS) is a sporadic condition. Even uncommon is an ECS that derives from a carcinoid tumor of the thymus. These tumors may pose several diagnostic and therapeutic conundrums.

Expression of Connexin43 Stimulates Endothelial Angiogenesis Independently of Gap Junctional Communication In Vitro.

Connexins (Cx) form gap junctions (GJ) and allow for intercellular communication. However, these proteins also modulate gene expression, growth, and cell migration. The downregulation of Cx43 impairs endothelial cell migration and angiogenetic potential.

Primary pulmonary extranodal natural killer/T-cell lymphoma (ENKTL), nasal type: Two case reports and literature review.

Introduction: Extranodal natural killer/T-cell lymphoma (ENKTL) - nasal type is an aggressive form of malignant non-Hodgkin lymphoma with a very poor prognosis. Especially primary pulmonary ENKTL is a relatively rare form of non-Hodgkin lymphoma. Until now, the prevalence of primary pulmonary ENKTL is unknown.

SP1 induced long non-coding RNA LINC00958 overexpression facilitate cell proliferation, migration and invasion in lung adenocarcinoma via mediating miR-625-5p/CPSF7 axis.

Background: Increasing evidences have underlined the importance of long non-coding RNAs (lncRNAs) in human malignancies. LINC00958 has been found involved in some cancers. However, the underlying mechanical performance of LINC00958 in lung adenocarcinoma (LAD) has not been explored yet.

Surgical Treatment of Tracheal Lipoma after Multiple Bronchoscopy Interventions and Placements of a Tracheal Stent.

 The majority of adult primary tracheal tumors are malignant; however, as one type of benign tumors, lipoma is extremely uncommon.  We report a case where lipoma was first misdiagnosed as bronchial asthma, followed by sudden aggravation of dyspnea after trauma, and computed tomography (CT) examination of the neck and chest confirmed a tracheal tumor. Through multiple bronchoscopy interventions and placements of a tracheal stent, little therapeutic benefit was discovered, and resection of the tracheal tumor combined with tracheal end-to-end anastomosis was performed to ultimately achieve a cure.

Surgical treatment of the severe thoracic gastrocutaneous fistula by pedicled muscle flap filling and thoracoplasty after oesophagectomy for oesophageal squamous cell carcinoma: A case report.

Background: Thoracic anastomotic fistula (TAF) is a severe postoperative complication of oesophagectomy, and its occurrence coupled with a thoracic gastrocutaneous fistula (TGCF) and tracheostenosis is very unusual and may lead to a fatal consequence.

Case Presentation: We describe a case of an old female diagnosed with mid-oesophageal carcinoma, who presented with a TAF after oesophagectomy, which was healed by an effective treatment, while a severe TGCF and tracheostenosis appeared one month postoperation. The complications were detected by gastroscopy, barium oesophagogram and thoracic computed tomography (CT).

TGF-β1 induces human aortic vascular smooth muscle cell phenotype switch through PI3K/AKT/ID2 signaling.

The vascular smooth muscle cell (VSMC) phenotypic switch is considered to be the key pathophysiological change in various cardiovascular diseases, such as aortic dissection, atherosclerosis, and hypertension. The results in this study showed that TGF-β1 promotes the proliferation, migration and morphological changes of VSMC.TGF-β1 promoted the expressions of PI3K, P-PI3K, AKT, P-AKT, ID2, and OPN protein and suppressed the expressions of α-SMA and SM22α protein; the opposite results were observed for TGF-β1 inhibitor group, AKT inhibitor group and Combined inhibitors group.
