Comparison of lobectomy performed through Toumai surgical robot and da Vinci surgical robot in early-stage non-small cell lung cancer: a retrospective study of early perioperative results.

Background: Robotic-assisted thoracic surgery (RATS) is a safe and efficient minimally invasive thoracic approach compared to thoracotomy. Today, almost all thoracic procedures can be performed by RATS. In recent years, the Chinese government has issued some policies to support the development of domestic surgical robots, leading to the development of the Toumai surgical robot system.

[Crucial Techniques for Chest Tube Placement and Postoperative Management].

Postoperative management of thoracic surgery with an indwelling chest tube is common, and knowledge about it is essential. A postoperative chest tube has four roles:1) to reinflate the lung, 2) to observe the condition of the thoracic cavity and acquire information regarding the outcomes, 3) to prevent complications, and 4) to treat pulmonary air leaks and empyema (chemical pleurodesis et ct). Although postoperative complications have decreased in recent years following advances in video-assisted thoracoscopic surgery( VATS) and devices such as stapling devices and vascular sealing systems (VSS), postoperative chest tube placement is still common.

Experimental and histological evaluation of different clamp technique for pulmonary artery.

Objectives: The double-loop technique has been used in our clinical settings for pulmonary arterioplasty and/or injured artery repair during thoracoscopic anatomical lung resection. We evaluated the pressure resistance capacity and intimal load to determine the effectiveness and safety of the double-loop technique.

Methods: The double-loop technique, DeBakey clamp, Fogarty clamp, endovascular clips and vessel loop technique were evaluated.

Highly sensitive detection of a HER2 12-base pair duplicated insertion mutation in lung cancer using the Eprobe-PCR method.

Somatic mutation in human epidermal growth factor receptor-related 2 gene (HER2) is one of the driver mutations in lung cancer. HER2 mutations are found in about 2% of lung adenocarcinomas (ADCs). Previous reports have been based mainly on diagnostic screening by Sanger sequencing or next-generation sequencing (NGS); however, these methods are time-consuming and complicated.

Prognostic potential of the MDM2 309T>G polymorphism in stage I lung adenocarcinoma.

The MDM2 protein plays an important role in the regulation of cell proliferation and apoptosis via ubiquitination and proteasome-mediated degradation of p53. The genetic polymorphism rs2279744 (c.309T>G) of the MDM2 gene is reportedly associated with susceptibility and/or prognosis in various cancers.

Eprobe-mediated screening system for somatic mutations in the KRAS locus.

Activating mutations in the Kirsten rat sarcoma viral oncogene homolog (KRAS) loci are largely predictive of resistance to epidermal growth factor receptor (EGFR) therapy in colorectal cancer (CRC). A highly sensitive detection system for the KRAS gene mutations is urgently needed; however, conventional methods have issues with feasibility and cost performance. Here, we describe a novel detection system using a fluorescence 'Eprobe' capable of detecting low level KRAS gene mutations, via real-time PCR, with high sensitivity and simple usability.

Single-nucleotide polymorphism (c.309T>G) in the gene and lung cancer risk.

Murine double minute 2 (MDM2) is a negative regulator of p53. A single-nucleotide polymorphism (SNP) (rs2279744: c.309T>G) in the promoter region of the gene has been shown to result in higher levels of MDM2 RNA and protein.
