Abstract
Non-small-cell lung cancer (NSCLC) is a frequent malignancy and has a high global incidence. Long noncoding RNAs (lncRNAs) are implicated in carcinogenesis and tumor progression. LncRNA testis developmental related gene 1 (TDRG1) plays a pivotal role in many cancers. This study researched the biological regulatory mechanisms of TDRG1 in NSCLC. Gene expression was assessed by reverse transcriptase quantitative polymerase chain reaction (RT-qPCR). Changes in the NSCLC cell phenotypes were examined using 5-ethynyl-2'-deoxyuridine (EdU), cell counting kit-8 (CCK-8), wound healing, flow cytometry, and Transwell assays. The binding capacity between TDRG1, microRNA-214-5p (miR‑214-5p), and Krüppel-like factor 5 (KLF5) was tested using luciferase reporter and RNA immunoprecipitation (RIP) assays. In this study, we found that TDRG1 was upregulated in NSCLC samples. Functionally, TDRG1 depletion inhibited NSCLC cell growth, migration, and invasion and accelerated apoptosis. In addition, TDRG1 interacted with miR-214-5p, and miR-214-5p directly targeted KLF5. The suppressive effect of TDRG1 knockdown on NSCLC cellular processes was abolished by KLF5 overexpression. Overall, TDRG1 exerts carcinogenic effects in NSCLC by regulating the miR-214-5p/KLF5 axis.

Abstract
The incidence and mortality of lung cancer ranks first among all malignant tumors in the world. Because it is relatively asymptomatic at early stages, most patients do not become aware of the disease until it has progressed to an advanced stage. Advanced lung cancer metastasis results
in systemic cachexia and effective treatment becomes challenging, leading to poor response and outcome. Therefore, the development of new drugs for the treatment of lung cancer is paramount. In this study, A549 cells were treated with different concentrations of red raspberry extract and the
proliferation, migration, and invasion of cells were evaluated. The results indicated that red raspberry extract reduced the proliferation, migration, and invasion of A549 cells. Western blot analysis was used to detect the expression of the cyclin D1, N-cadherin, vimentin, E-cadherin, EGFR,
and STAT3 proteins. Treatment with red raspberry extract reduced the expression of cyclin D1, N-cadherin, vimentin, EGFR, and STAT3, whereas the expression of E-cadherin increased. Following transfection of an EGFR overexpression vector into A549 cells, we observed a reduced inhibitory effect
of the red raspberry extract on the proliferation, migration, and invasion of A549 cells. In addition, EGFR overexpression abrogated the increased expression of cyclin D1, N-cadherin, vimentin, EGFR, and STAT3 protein expression in A549 cells following extract treatment. In contrast, E-cadherin
protein expression was decreased under these treatment conditions. Overall, this study suggests that red raspberry extract may reduce the proliferation, migration, invasion, and epithelialmesenchymal transition of A549 lung cancer cells by inhibiting the activation of the EGFR/STAT3 signaling
pathway. These findings may lead to the development of new strategies to treat advanced lung cancer.

Abstract
THIS special article is the 4th in an annual series for the Journal of Cardiothoracic and Vascular Anesthesia. The authors thank the editor-in-chief, Dr. Kaplan; the associate editor-in-chief, Dr. Augoustides; and the editorial board for the opportunity to expand this series, the research highlights of the year that specifically pertain to the specialty of thoracic anesthesia. The major themes selected for 2019 are outlined in this introduction, and each highlight is reviewed in detail in the main body of the article. The literature highlights in this specialty for 2019 include updates in the preoperative assessment and optimization of patients undergoing lung resection and esophagectomy, updates in one lung ventilation (OLV) and protective ventilation during OLV, a review of recent meta-analyses comparing truncal blocks with paravertebral catheters and the introduction of a new truncal block, meta-analyses comparing nonintubated video-assisted thoracoscopic surgery (VATS) with those performed using endotracheal intubation, a review of the Society of Thoracic Surgeons (STS) recent composite score rating for pulmonary resection of lung cancer, and an update of the Enhanced Recovery After Surgery (ERAS) guidelines for both lung and esophageal surgery.
