Single-cell RNA sequencing reveals the mechanism of PI3K/AKT/mTOR signaling pathway activation in lung adenocarcinoma by KRAS mutation.

Background: Aberrant activation of the phosphatidlinositol 3-kinase (PI3K)/protein kinase B (AKT)/mammalian target of rapamycin (mTOR) signaling pathway has been shown to play an important role in lung adenocarcinoma (LUAD). The effect of KRAS mutations, one of the important signatures of LUAD, on the PI3K/AKT/mTOR pathway in LUAD remains unclear.

Methods: The Seurat package and principal component analysis were used for cell categorization of single-cell RNA sequencing data of LUAD.

Diagnosis and treatment of high-risk bilateral lung ground-glass opacity nodules.

In recent years, there has been a significant increase in the detection rate of Ground Glass Opacity (GGO) nodules through high-resolution computed tomography (HRCT). GGO is an imaging finding that encompasses various pathological types, some of which exhibit indolent growth, while others may represent early lung cancer or remain relatively stable, not significantly impacting the surgical treatment outcome. In clinical practice, patients often experience psychological anxiety when multiple pulmonary GGO nodules are present, and they may request simultaneous resection.

Analyzing robotic surgery impact on recovery quality & emotions.

Background: The objective of this study is to investigate the postoperative recovery quality and emotional status of patients with non-small cell lung cancer (NSCLC) who underwent robot-assisted and video-assisted thoracoscopic surgery using the 15-item Quality of Recovery (QoR-15) scale and to analyze the correlation.

Methods: We collected clinical data from 320 patients with NSCLC who underwent lobectomy using either robot-assisted thoracoscopic surgery (RATS) or video-assisted thoracoscopic surgery (VATS) at our center from January 2021 to December 2022. We compared perioperative parameters and followed up after the operation using the QoR-15 scale to objectively assess the quality of postoperative recovery and physical and emotional status.

miR-140-3p enhances the sensitivity of LUAD cells to antitumor agents by targeting the ADAM10/Notch pathway.

The Notch pathway, which is related to the drug-resistance of lung adenocarcinoma (LUAD) type of non-small cell lung cancer (NSCLC) cells, is activated by cleavage of Notch proteins mediated by ADAMs, ADAM10 or ADAM17. In the present study, our results demonstrated that of these two ADAMs, the expression of ADAM10 in clinical samples of the LUAD type of NSCLC was much higher than that of ADAM17, while miR-140-3p - an miRNA that could target ADAM10 - was identified by an online tool: miRDB (miRNA database). The detail function and mechanism of miR-140-3p in regulating the sensitivity of NSCLC cells to antitumor drugs was systematically explored and .

[Survival Analysis of Stage I Non-small Cell Lung Cancer Patients Treated with Da Vinci Robot-assisted Thoracic Surgery].

Background: Da Vinci robotic surgery system is widely used in department of thoracic surgery. The aim of this study is to investigate the treatment outcome of stage I non-small cell lung cancer (NSCLC) via da Vinci Surgical System.

Methods: Clinical date of 347 stage I NSCLC patients, who underwent lobectomy and systematic node dissection from Jan.

[A Paired Case Controlled Study Comparing the Short-term Outcomes of Da Vinci RATS and VATS Approach for Non-small Cell Lung Cancer].

Background: Da Vinci Surgical System is one of the greatest inventions of the 20th century, which represents the development direction of the precise minimally invasive surgical techniques, the aim of this study was to comparing the short-term outcomes between da Vinci robot-assisted lobectomy and video-assisted thoracic surgery (VATS) lobectomy for non-small cell lung cancer.

Methods: 45 pairs of non-small cell lung cancer patients underwent pulmonary lobectomy with da Vinci Robotic assisted thoracoscopic (RATS) and VATS approach during the same period from January 2014 to January 2017. The operative time, estimated blood loss (EBL), total number and total groups of dissected lymph nodes, postoperative duration of drainage, the first day volume of drainage, total volume of drainage were compared.

[A comparative study of Da Vinci robot system with video-assisted thoracoscopy in the surgical treatment of mediastinal lesions].

Background: In recent years, Da Vinci robot system applied in the treatment of intrathoracic surgery mediastinal diseases become more mature. The aim of this study is to summarize the clinical data about mediastinal lesions of General Hospital of Shenyang Military Region in the past 4 years, then to analyze the treatment effect and promising applications of da Vinci robot system in the surgical treatment of mediastinal lesions.

Methods: 203 cases of mediastinal lesions were collected from General Hospital of Shenyang Military Region between 2010 and 2013.

[Clinical experience of the treatment of solitary pulmonary nodules with Da Vinci surgical system].

Background: A solitary pulmonary nodule (SPN) is defined as a round intraparenchimal lung lesion less than 3 cm in size, not associated with atelectasis or adenopathy. The aim of this study is to learn clinical experience of the treatment of SPN with Da Vinci Surgical System.

Methods: A total of 9 patients with solitary pulmonary nodules (SPN) less than 3 cm in diameter was treated with Da Vinci Surgical System (Intuitive Surgical, California) in thoracic surgery department from General Hospital of Shenyang Militrary Region from November 2011 to March 2014.
