ABSTRACT
Aim To investigate the possible mechanism of quercetin in promoting apoptosis of breast cancer cells. Methods Breast cancer cells MCF-7 were treated with quercetin. Cell viability was detected by MTT assay, cell proliferation and cloning ability were measured by plate colony formation assay, and cell apoptosis was examined by Annexin V-FITC/PI double staining assay. Meanwhile, MCF-7 cells were treated with quercetin (40, 80, 160 μmol · L
ABSTRACT
Glucagon-like peptide-1 (GLP-1) is an incretin hormone that is currently used clinically to control blood glucose in patients with type 2 diabetes mellitus.Recent studies have found that GLP-1 and its receptors are expressed in the human retina.Now GLP-1 and its analogues for the prevention and treatment of diabetic retinopathy has become a research focus,so this article will give a brief review on the recent advances in GLP-1 and its analogues for the treatment of DR.
ABSTRACT
Objective To explore the data accuracy acquired by the anesthesia information management system.Methods Totally 100 patients from two hospitals were selected randomly,whose anesthesia time was estimated more than 1 h.The vital signs data acquired by the system were compared with those by the monitor once every 5 min±30 s,and totally there were 12 times of comparison executed.SAS 9.2 software was used for statistical analysis.Results In FAS set the system had the total data accuracy being 100％,95％ credibility interval from 86.87％ to 97.30％ and the BMDL higher than 85％;in PPS set he total data accuracy was 100％,95％ credibility interval was from 92.89％ to 100％ and the BMDL was also higher than 85％.The system gained "Excellent" or "Good" grade in system response,stability,functional interface operability and the accuracy of special functions.Conclusion The system acquires and stores the vital signs data automatically and accurately,enhances anesthesia information in objectivity,authenticity and tractability,and has high values for enhancing anesthesia safety,medical safety and scientific research.
