With the rapid development of science and technology, and the improvement of production safety and management standards, the use of expert system to bridge crane operator teaching simulation to train high quality personnel has become a pressing need. But it is hard to evaluate the train result. This paper aims at developing a bridge crane training system(More)
BACKGROUND Little is known about the outcomes of endoscopic submucosal dissection in elderly patients with superficial squamous esophageal neoplasms. OBJECTIVE To assess the efficacy and safety of endoscopic submucosal dissection for superficial squamous esophageal neoplasms in elderly patients (≥65 years) compared with non-elderly patients. METHODS All(More)
Recently, several studies have shown that piperlongumine (PL) can selectively kill cancer cells by targeting reactive oxygen species (ROS). However, the potential therapeutic effects and detailed mechanism of PL in gastric cancer are still not clear. In the current report, we found that PL significantly suppressed gastric cancer both in vitro and in vivo.(More)
In the liver, the signal and function of tumor necrosis factor-like weak inducer of apoptosis (TWEAK) have mainly been assessed in association with liver regeneration. However, the effects of TWEAK on liver fibrosis have not been fully elucidated. To investigate the effects of TWEAK on human hepatic stellate cells (HSCs) and to explore the relevant(More)
Snail, a family of zinc finger transcription factors, plays an important role in morphogenesis and embryogenesis. Snail zinc finger family 2 (SNAI2 or Slug) has been demonstrated to regulate carcinogenesis of several human cancers including breast, prostate, head, neck, pancreas and endometrial carcinomas (Zhang et al., 2011; Markiewicz et al., 2012;(More)
In order to train high quality overhead crane operating personnel, overhead crane operator training system based on virtual reality is imperative and in great demand. This paper aims at developing an Overhead crane training system based on virtual reality technology. The article points out that the application of virtual reality technology will be trend in(More)
Mupirocin is the first-line topical antibacterial drug for treating skin infections caused primarily by meticillin-resistant Staphylococcus aureus (MRSA). Its widespread use since its introduction more than 30 years ago has resulted in the global emergence of mupirocin-resistant strains of MRSA. Antimicrobial peptides (AMPs) are a promising class of(More)
The purpose of this study is to compare the clinicopathological characteristics and outcomes of esophageal foreign body (FB) ingestion in adults between weekdays and holidays. This is a retrospective study including 1058 patients with esophageal FB ingestion from 2012 to 2016. Patient characteristics, the types and locations of FB, and clinical outcomes(More)
The effect of proton pump inhibitor (PPI) on cancer risk has received much attention recently. In this study, we investigated the mechanism underlying multidrug resistance and the effect of a PPI pantoprazole using an adriamycin-resistant gastric cancer cell model (SGC7901/ADR). Compared with the parental cell line, SGC7901/ADR cells showed reduced(More)
