BACKGROUND/AIMS Elderly patients with gastrointestinal stromal tumors (GISTs) synchronous with other digestive tract malignancies have been rarely reported. In this study, clinicopathological characteristics were evaluated among elderly patients with GISTs with or without coexisting digestive tract malignancies. METHODS A total of 161 patients (≥65 years)(More)
Increasing evidence suggests that hsa-miR-126 (miR-126) is down-regulated in non-small cell lung cancer (NSCLC) cell lines and the restoration of miR-126 impairs tumor cell proliferation, migration, invasion, and survival by targeting specific molecules. Here, we reported for the first time that miR-126 was involved in regulating the response of NSCLC cells(More)
We investigate the problem of minimizing spectrum resource consumption for a set of connection requests in a flexible bandwidth optical network under the constraint that the failure probability of each connection must be below a specified threshold. To optimize the total frequency slots consumed, three schemes are proposed and evaluated: the rescaled(More)
Reactive oxygen species (ROS)-driven oxidative stress has been recognized as a critical inducer of cancer cell death in response to therapeutic agents. Our previous studies have demonstrated that zinc finger protein (ZNF)32 is key to cell survival upon oxidant stimulation. However, the mechanisms by which ZNF32 mediates cell death remain unclear. Here, we(More)
Endoscopic resection has been performed to treat small gastric neoplasms. However, this technique for small gastric gastrointestinal stromal tumors (GISTs) remains controversial. This study aims to compare the safety and surgical outcomes of endoscopic versus open resection of small gastric GISTs.The medical records of 54 consecutive gastric GISTs patients(More)
Immune cells contribute to determining the prognosis of gastric cancer. However, their exact role is less clear. We determined the prognostic significance of different immune cells in intratumoral tissue (T), stromal tissue (S), and adjacent normal tissue (N) of 166 gastric cancer cases and their interactions, including CD3+, CD4+, CD8, CD57+, CD68+,(More)
BACKGROUND Gastric neuroendocrine neoplasms (G-NENs) are uncommon, and data on their management is limited. We here investigated the clinicopathological characteristics, surgical and survival outcomes in G-NENs among Chinese. Moreover, we will discuss their prognostic value. METHODS From existing databases of the West China Hospital, we retrospectively(More)
In this paper, an efficient scheduling algorithm based on critical path suitable for dependent tasks (DAG scheduling) in grid computing has been presented. With the object to shorten the makespan greatly, a new approach for constructing the task list has been developed, and an efficient processor selection procedure has also been developed.
Glutathione S-transferases (GSTs) are a large family of phase II detoxification enzymes that are expressed in many tissues and play critical roles in protecting hosts against cancer. The association of glutathione S-transferase M1 (GSTM1) polymorphism with susceptibility to colorectal cancer in Asians has not been well established. We performed a(More)
OBJECTIVES Despite its rising popularity, reports on the use of preoperative imatinib mesylate (IM) in patients with advanced gastrointestinal stromal tumor (GIST) are limited. This study aims to explore the clinical efficacy of preoperative IM in patients with primarily unresectable or metastatic/recurrent GIST. METHODS Between September 2009 and(More)
