The incidence of colorectal cancer (CRC) in young patients (≤ 50 years of age) appears to be increasing. However, their clinicopathological characteristics and survival are controversial. Likewise, the biomarkers are unclear. We used the West China (2008-2013, China), Surveillance, Epidemiology, and End Results program (1973-2011, United States) and(More)
As one strategy of power management, microgrid has the special superiorities on not only improving power quality but also relieving the pressure on energy and environment. To carry out experiment and research, a small laboratory-scale microgrid system with energy storage device, single phase and three-phase photovoltaic devices and wind power devices are(More)
The present study aimed to assess the efficacy of surgery and adjuvant therapy in older patients (age≥70 years) with colorectal cancer (CRC). Older CRC patients are under-represented in available clinical trials, and therefore their outcomes after receiving surgery and adjuvant therapy are unclear. From two prospective Swedish databases, we assessed a(More)
INTRODUCTION K-ras gene mutations were common in colorectal patients, but their relationship with prognosis was unclear. OBJECTIVE Verify prognostic differences between patient with and without mutant K-ras genes by reviewing the published evidence. METHOD Systematic reviews and data bases were searched for cohort/case-control studies of prognosis of(More)
OBJECTIVE There is increasing evidence to indicate that MMP-7 plays a more important role in tumor progression than other MMPs. The aim of this study was to detect MMP-7 expression in human rectal cancer and normal rectal tissue and to determine whether it is correlated with invasion and metastasis of human rectal cancer. METHODS Eighty-six paired samples(More)
The lymph node ratio (LNR) (i.e. the number of metastatic lymph nodes divided by the number of totally resected lymph nodes) has recently emerged as an important prognostic factor in colorectal cancer (CRC). However, the tumor node metastasis (TNM) staging system for colorectal cancer does not consider it as a prognostic parameter. Therefore, we conducted a(More)
The present study aimed to assess the efficacy of surgery and adjuvant therapy in older patients (age !70 years) with colorectal cancer (CRC). Older CRC patients are under-represented in available clinical trials, and therefore their outcomes after receiving surgery and adjuvant therapy are unclear.
