No clear consensus has been reached on the XPA gene rs1800975 polymorphism and lung cancer risk. We performed a meta-analysis in an effort to systematically explore the possible association. We conducted a computer retrieval of PubMed, Embase, Wanfang, China National Knowledge Infrastructure Platform, and VIP databases prior to November 2013. References of(More)
OBJECTIVE To evaluate the efficacy and safety of icotinib hydrochloride in patients with advanced non-small cell lung cancer (NSCLC). METHODS A total of 89 patients with stage IIIB or IV NSCLC received icotinib at a dose of 125 mg administered 3 times a day. Icotinib treatment was continued until disease progression or development of unacceptable(More)
INTRODUCTION Early prediction of the efficacy of a combination of an antiangiogenic drug with cytotoxic chemotherapy is a significant challenge. In that regard, circulating endothelial cells (CECs) and cytokeratins (CKs) seem to reflect their roles in both tumor angiogenesis and tumor cell death. METHODS Patients with advanced, previously untreated(More)
The molecular mechanism underlying activation of matrix metallopeptidase 9 (MMP9) in non-small cell lung cancer (NSCLC) cells, which controls cancer invasiveness and metastasis, remains elusive. Here, we reported a strong correlation of epidermal growth factor receptor (EGFR) and MMP9 levels in NSCLC patients. Thus, we used a human NSCLC line, A549, to(More)
Surface engineering of crystals at nanoscale level by precisely and rationally exposing specific facets proved to be highly effective in enhancing the performance of inorganic functional nanocrystals. To do so, a comprehensive understanding of the growth mechanism was of great importance. By using hematite (α-Fe2O3) as an example, in this paper we(More)
Assessment tools and body-composition measurements are useful in diagnosing malnutrition. Which one is better for lung disease patients is unclear. The objectives of the present study are: to assess relationships between different methods of nutritional measurements in lung diseases patients; to determine which one is better in diagnosing malnutrition for(More)
The influence of metal vapour on the arc behaviour during the arc-splitting process in the quenching chamber of a low-voltage circuit breaker is investigated numerically. A three-dimensional magnetohydrodynamic model of air arc plasma, taking into account the production of metal vapour from erosion of an iron splitter plate, is developed. An equation(More)
