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)
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)
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)
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)
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)
This paper investigates a three-stage supply chain scheduling problem in the application area of aluminium production. Particularly, the first and the third stages involve two factories, i.e., the extrusion factory of the supplier and the aging factory of the manufacturer, where serial batching machine and parallel batching machine respectively process jobs(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)
This paper investigates the scheduling problems of a single serial-batching machine with independent setup time and deteriorating job processing times. With the assumption of deteriorating jobs, the job processing times are described by an increasing function of their starting times. All the jobs are first partitioned into serial batches and then processed(More)
