BACKGROUND Robotic surgery has been used successfully in many branches of surgery; but there is little evidence in the literature on its use in rectal cancer (RC). We conducted this meta-analysis that included randomized controlled trials and nonrandomized controlled trials of robotic total mesorectal excision (RTME) versus laparoscopic total mesorectal(More)
In order to study the relationships between trace element concentrations of hair and internal body burdens, a radiochemical NAA technique has been used for determination of the elements As, Cd, and Hg in autopsy samples of liver, kidney-cortex, lung, and hair from 24 male persons who died by accident. High significant positive correlations were observed(More)
AIMS To assess the efficacy and safety of neoadjuvant chemotherapy (NAC) for advanced gastric cancer (AGC). METHODS By searching electronic databases (PubMed, Embase, Cochrane Library) and ASCO proceedings from 1990 to 2012, all randomized controlled trials (RCTs) which compared the effect of NAC-combined surgery versus surgery alone in AGC were included.(More)
AIMS The standard surgical procedure for elderly (≥ 70 years) patients with clinical stage I non-small cell lung cancer (NSCLC) was investigated. METHODS A non-randomized prospective controlled study was conducted to compare lobectomy with segmental resection for the treatment of elderly clinical stage I lung cancer patients under different pulmonary(More)
The correlations of essential element Se between human hair and kidney-cortex, liver, and lung from the same subjects were investigated by instrumental neutron activation analysis, using the reaction 76Se (n, gamma) 77mSe, for 24 Chinese autopsies. The concentration of Se is higher in kidney-cortex (2.04-5.36 mg/kg) than in liver (0.73-2.29), lung(More)
BACKGROUND Fourier-transform infrared spectroscopy (FT-IR) is a powerful tool for study of the secondary conformation of intact protein in biological tissues and for diagnosis of disease states. The purpose of this study is to utilize FT-IR as a diagnostic tool to estimate the secondary structure of amide I in normal and cancer tissue of human colon. (More)
