Biomechanical strength dependence on mammalian airway length.

Background: The trachea is the uppermost respiratory airway element connecting the larynx to the bronchi Airway reconstructions in humans are often developed from animal models but there is limited knowledge comparing tracheal biomechanics between species. We aimed to assess the structure and biomechanics of porcine, canine, caprine and human airways.

Methods: Tracheas from pigs (n=15), goats (n=9) and canines (n=9) were divided into three groups (4, 6 and 8-ringswhile human left principal brochi (n=12) were divided into two groups (3and-rings).

Aberrantly High Expression Of NOK/STYK1 Is Tightly Associated With The Activation Of The AKT/GSK3β/N-Cadherin Pathway In Non-Small Cell Lung Cancer.

Purpose: High metastasis is a leading risk factor for the survival of non-small cell lung cancer (NSCLC) and epithelial-mesenchymal transition (EMT) is a vital step of metastasis. The expression of novel oncogene with kinase domain (NOK) has been observed in some human malignancies, including non-small cell lung cancer (NSCLC); however, the biological function of NOK in NSCLC remains unclear. In the study, we explored the function of NOK in NSCLC, with an aim to elucidate the relevant underlying mechanisms.

Knockdown of MALAT1 expression inhibits HUVEC proliferation by upregulation of miR-320a and downregulation of FOXM1 expression.

Regulation of cancer angiogenesis could be a useful strategy in cancer therapy. Metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) is a long non-coding RNA (lncRNA), and can induce cancer cell proliferation, while lncRNAs, generally are able to act as microRNA (miRNA) sponges. The latter is a type of competitive endogenous RNA (ceRNA) that regulates expression of the targeting miRNAs and protein-coding genes.

A novel surgical method for acquired non-malignant complicated tracheoesophageal and bronchial-gastric stump fistula: the "double patch" technique.

Background: To manage the acquired benign complicated tracheoesophageal fistula (TEF) and bronchial-gastric stump fistula (BGSF) are clinical technical challenge. The purpose of this study is to retrospectively review a surgical "double patch" technique in treating nonmalignant complicated TEF and BGSF, and then clarify the long-term curative effect of the technique.

Methods: Clinical records of 30 patients with non-malignant complicated TEF and BGSF treated by "double patch" technique in Tangdu Hospital between August 2004 and August 2014, were analyzed and summarized retrospectively.

Effect of cauterizing esophageal mucosa in "double-patch" treatment for acquired benign tracheoesophageal fistula/bronchogastric stump fistula.

Background: The management of acquired benign tracheoesophageal fistula (TEF) and bronchogastric stump fistula (BGSF) is a challenge. This study aimed to assess the "double-patch" technique with or without esophageal mucosa in treating nonmalignant TEF and BGSF.

Materials And Methods: We established a dog model with TEF by incising the esophageal and tracheal membranes and suturing them together.

Inhibiting CREPT reduces the proliferation and migration of non-small cell lung cancer cells by down-regulating cell cycle related protein.

It has been reported that CREPT acts as a highly expressed oncogene in a variety of tumors, affecting cyclin D1 signal pathways. However, the distribution and clinical significance of CREPT in NSCLC remains poorly understood. Our study focused on the role of CREPT on the regulation ofnon-small cell lung cancer (NSCLC).

Clinicopathologic features and prognostic implications of Gankyrin protein expression in non-small cell lung cancer.

Purpose: The expression of Gankyrin, a liver cancer-related oncoprotein, has been observed in several human malignancies including non-small cell lung cancer (NSCLC). However, the clinic relevance of Gankyrin expression in NSCLC remains unclear.

Methods: Gankyrin expression was assessed using immunohistochemical (IHC) methods in 166 paired paraffin-embedded NSCLC specimens and adjacent normal tissues.

Effect of Intravascular Ultrasound-assisted Thoracic Endovascular Aortic Repair for "Complicated" Type B Aortic Dissection.

Background: Intravascular ultrasound (IVUS) examination can provide useful information during endovascular stent graft repair. However, its actual clinical utility in thoracic endovascular aortic repair (TEVAR) for type B aortic dissection (type B-AD) remains unclear, especially in complicated aortic dissection. We evaluated the effect of IVUS as a complementary tool during TEVAR.

Clinicopathologic features and prognostic implications of NOK/STYK1 protein expression in non-small cell lung cancer.

Background: The expression of novel oncogenic kinase (NOK), a member of the protein tyrosine kinase (PTK) family, has been observed in several human malignancies including non-small cell lung cancer (NSCLC). However, the clinic relevance of NOK expression in NSCLC remains unclear.

Methods: In this study, NOK expression in tumor cells was assessed using immunohistochemical methods in 191 patients with resected NSCLC.

Management of multiple type II endoleaks detected by duplex ultrasound after endovascular abdominal aneurysm repair.

We reported a case of multiple type II endoleaks detected by duplex ultrasound after endovascular abdominal aneurysm repair. The patient was undergoing warfarin therapy. Duplex ultrasound was applied as the sole surveillance method during follow-up and provided the concerned information for reintervention.

[Analysis of contrast medium induced pancreatitis].

Objective: To report the contrast medium induced pancreatitis after angiography or endovascular therapy, analyze the possible cause of this complication, the treatment specialty and the prognosis.

Method: The patients suffered from contrast medium induced pancreatitis after angiography or endovascular therapy during last 10 years were retrospectively analyzed. The patients' comorbidity, the onset time of the pancreatitis, the specialty of the pancreatitis, the treatment method and the prognosis were documented.

[Endovascular repair of descending thoracic aortic aneurysm: preliminary experience].

Objective: To report an initial experience with the endovascular repair of descending thoracic aortic aneurysm (DTAA).

Methods: Endoprostheses were placed into 41 patients with DTAA between January 2001 and July 2007 which were retrospectively analyzed. The preliminary right-left carotid and left carotid-subclavian bypass was performed in 4 cases in which the distances from the proximal aneurysm to the origin of the left common carotid artery were no longer than 15 mm.
