Skin has excellent capacity to regenerate, however, in the event of a large injury or burn skin grafts are required to aid wound healing. The regenerative capacity further declines with increasing age and can be further exacerbated with bacterial infection leading to a chronic wound. Engineered skin substitutes can be used to provide a temporary template for the damaged tissue, to prevent/combat bacterial infection and promote healing.

An electrospinning technique was used to produce three-dimensional (3D) bioactive glass fibrous scaffolds, in the SiO-CaO sol-gel system, for wound healing applications. Previously, it was thought that 3D cotton wool-like structures could only be produced from sol-gel when the sol contained calcium nitrate, implying that the Ca and its electronic charge had a significant effect on the structure produced. Here, fibres with a 3D appearance were also electrospun from compositions containing only silica.

In this study, we investigated the expression patterns and functional roles of microRNA 127 (miR-127) and its target gene Formin-Like 3 (FMNL3) in human esophageal squamous cell carcinoma (ESCC). Quantitative RT-PCR (qRT-PCR) was used to compare miR-127 expression between ESCC cell lines and normal esophageal epithelium cell line, as well as paired ESCC tumors and adjacent normal esophageal tissues in 33 patients. We found miR-127 was aberrantly downregulated in both ESCC cell lines and human ESCC tumors.

In recent years, thoracoscopic lobectomy has been rapidly developing and applied in China with an ever growing list of indications as the resectable range has been evolving from the peripheral type to the central type, from a diameter less than 3 cm to greater than 5 cm, and from lobectomy to pneumonectomy and segmental lung resection. This technique has become a routine option in our department. This video shows one case of thoracoscopic lobectomy with lymph node dissection for upper right lung cancer of 6 cm in diameter.

Purpose: To investigate the prevalence of phosphatidylinositol 3-kinase (PIK3CA) gene amplification in lung cancer, and to explore its prognostic value.

Methods: A total of 647 lung tumor samples from 290 patients were included in the study. The ratio of PIK3CA signals/centromere 3 signals in cancer cells was estimated by fluorescence in situ hybridization (FISH7rpar; analysis.

N-Myc downstream-regulated gene 2 (NDRG2) has been demonstrated to influence the metastatic potential of hepatocellular carcinoma and breast cancer cells by regulating CD24 expression. The aim of this study was to investigate the roles of NDRG2 and CD24 in the clinical pathology of lung adenocarcinoma and to explore whether the expression of these two markers can be used as independent factors for the prediction of prognosis in patients with this tumor. NDRG2 and CD24 expression in paraffin-embedded specimens gathered from 166 patients with lung adenocarcinoma was detected by immunohistochemical method.
