Effects of Ultrasonic Surface Rolling Processing and Subsequent Recovery Treatment on the Wear Resistance of AZ91D Mg Alloy.

AZ91D Mg alloy was treated by ultrasonic surface rolling processing (USRP) and subsequent recovery treatment at different temperatures. The dry sliding friction test was performed to investigate the effects of USRP and subsequent recovery treatment on the wear resistance of AZ91D Mg alloy by a ball-on-plate tribometer. The microstructure, properties of plastic deformation layer and worn morphology were observed by optical microscope (OM), scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray diffraction (XRD) analysis and microhardness tester.

Esophageal cancer patients of heavier weight have more nutritional risk of inadequate calorie intake immediately after esophagectomy: a retrospective study.

Background: Perioperative malnutrition is common in patients undergoing esophagectomy, and nutritional support is critical for postoperative recovery in these patients. But few studies reported which characteristics of these patients were associated with post-esophagectomy inadequate calorie intake. This study aimed to explore which patients were more likely to have inadequate calories immediately after esophagectomy and the impact on clinical outcomes.

Application of Modified Tailed Microcoil in Preoperative Localization of Small Pulmonary Nodules: A Retrospective Study.

Background: The localization of small pulmonary nodules (SPNs) during video-assisted thoracoscopic surgery (VATS) is challenging thoracic surgeon, especially in patients with severe pleural adhesion or visceral pleura pigmentation due to low success rate and future conversion to thoracotomy. This study aims to compare the efficacy and safety between modified microcoil and methylene blue in preoperative localization of small nodules, particularly patients with severe pleural adhesion or visceral pleura pigmentation.

Materials And Methods: From January 2018 to February 2019 in our institute, 342 patients who underwent computed tomography-guided localization of SPN were recruited in this retrospective cohort study and divided into the modified microcoil group ( = 239) and the methylene blue group ( = 103) according to the localization method.

Efficacy of 4 wk of home enteral feeding supplementation after esophagectomy on immune function: A randomized controlled trial.

Objectives: In recent years, home enteral nutrition (HEN) has been adopted as a feasible and safe form of nutrition for patients undergoing esophagectomy. The aim of this study was to compare the effects of 4 wk of HEN with standard enteral nutrition (SEN) on immune function, nutritional status, and survival in patients undergoing esophagectomy.

Methods: A parallel-group, randomized, single-blind, clinical trial was conducted between April 1 and August 1, 2017.

Synaptotagmin 12 (SYT12) Gene Expression Promotes Cell Proliferation and Progression of Lung Adenocarcinoma and Involves the Phosphoinositide 3-Kinase (PI3K)/AKT/Mammalian Target of Rapamycin (mTOR) Pathway.

BACKGROUND This study aimed to use bioinformatics analysis to compare data from tissue microarrays from patients with lung adenocarcinoma (LUAD) and normal lung tissue, and human lung adenocarcinoma cells with normal lung epithelial cells in vitro to investigate the role of synaptotagmin 12 (SYT12) gene expression in LUAD. MATERIAL AND METHODS Human lung adenocarcinoma cell lines (A549, SPC-A-1, H1299, H1975, and PC9) and the normal HBE cell line were compared, and tumor xenografts were developed in mice. The Cancer Genome Atlas (TCGA) tissue microarray data were used to compare SYT12 expression and overall survival (OS).

Effect of different therapeutic strategies on the clinical outcome of asymptomatic intralobar pulmonary sequestration.

Objectives: Pulmonary sequestration is a rare congenital pulmonary malformation. The aim of this study was to explore the effect of different therapeutic strategies on the clinical outcome of asymptomatic intralobar pulmonary sequestration.

Methods: We retrospectively reviewed the clinical data of 37 patients diagnosed with intralobar sequestration.

FAM111B, a direct target of p53, promotes the malignant process of lung adenocarcinoma.

Lung adenocarcinoma (LUAD) is a main subtype of lung cancer, which is the leading cause of cancer-related deaths. The five-year survival rates of lung cancer patients are still comparatively low. Therefore, potential therapeutic targets are urgently needed to improve the survival of lung cancer patients.

PITX2 enhances progression of lung adenocarcinoma by transcriptionally regulating WNT3A and activating Wnt/β-catenin signaling pathway.

Background: The homeodomain transcription factor, PITX2 is associated with tumorigenesis of multiple cancers. In this research, we aimed to study the expression, function and mechanism of PITX2 in lung adenocarcinoma (LUAD).

Methods: The TCGA dataset was used to analyze the expression and clinical significance of PITX2 in LUAD.

DMBX1 promotes tumor proliferation and regulates cell cycle progression via repressing OTX2-mediated transcription of p21 in lung adenocarcinoma cell.

Lung adenocarcinoma (LUAD) was the predominant histological subtype of lung cancer, with poor prognosis. By analyzing the TCGA dataset, we found that DMBX1 (diencephalon/mesencephalon homeobox 1), a member of the bicoid sub-family of homeodomain-containing transcription factors, was overexpressed in LUAD and correlated with poorer prognosis and more advanced clinicopathological features of LUAD patients. Silencing of DMBX1 inhibited proliferation of LUAD and induced G1/S cell cycle arrest, whereas ectopic expression of DMBX1 enhanced tumor growth of LUAD and promoted G1/S cell cycle exit.

C-reactive protein to albumin ratio is a key indicator in a predictive model for anastomosis leakage after esophagectomy: Application of classification and regression tree analysis.

Background: Anastomotic leakage (AL), a serious complication after esophagectomy, might impair patient quality of life, prolong hospital stay, and even lead to surgery-related death. The aim of this study was to show a novel decision model based on classification and regression tree (CART) analysis for the prediction of postoperative AL among patients who have undergone esophagectomy.

Methods: A total of 450 patients (training set: 356; test set: 94) with perioperative information were included.

Baicalin suppresses proliferation, migration, and invasion in human glioblastoma cells via Ca-dependent pathway.

Objective: Baicalin, a kind of flavonoid extracted from the dry root of Scutellaria, possesses potent anticancer bioactivities in various tumor cell lines. Accumulating evidences show that baicalin induces autophagy and apoptosis to suppress the cancer growth. Moreover, the antineoplastic role of baicalin in human glioblastoma cells remains to be uncovered.
