ABSTRACT
The graphene prepared by chemical vapor deposition onto copper foils was transferred onto a poly(ethylene terephthalate) (PET) soft substrate by the aid of poly-methyl methacrylate (PMMA).The soft G/AuNPs/GOD composite electrode based on PET substrate was fabricated using a protocol in which the uniform distribution of Au nanoparticles (AuNPs) was firstly obtained by controlling the evaporation of gold sol on a graphene surface, then thioglycolic acid (TGA) was modified on the AuNPs through Au-S bond, and finally glucose oxidase (GOD) was immobilized on the surface of AuNPs through acylation reaction between TGA and the GOD.Glucose was detected in the linear range from 0.05 to 10.55 mmol/L with a linear correlation coefficient (r) of 0.9955.The detection was performed in phosphate buffer solution (pH 7) at 25℃ with a working potential of 0.6 V (vs.SCE electrode), and the detection limit was 1 μmol/L (3σ).The G/AuNPs/GOD flexible electrode based on PET substrate provided a new pathway to detect glucose in special environments using wearable equipment, which enlarged the applied field of glucose detection.
ABSTRACT
Objective To investigate the application of extended nursing in patients with esophageal carcinoma . Methods 70 cases of patients with esophageal cancer from March 2015 to June 2016 in our hospital as the research object , according to the different nursing methods , 70 patients were randomly divided into control group and observation group , and the control group was given routine nursing , the observation group based on routine on the increase of nursing continuing nurs -ing care, nursing intervention after 6 months, compared two groups of patients with clinical effect .Results The patients in the observation group were better than the control group on health knowledge ;The complication rate of observation group was 34.3%, and the control group and the complication rate was 80%.The complication rate of the observation group was less than the control group;The observation group self care ability is better than the control group;The observation group satisfac-tion 94.3%;The control group satisfaction 65.7%, and the nursing satisfaction in the observation group are better than the control group;Two groups had significant differences , with statistical significance (P<0.05).Conclusion The continuous nursing intervention can effectively improve patients with esophageal carcinoma after discharge of quality of life , improve the self nursing ability of patients , reduce the incidence of complications , improve nursing satisfaction , which is conducive to the rehabilitation of patients , and is worthy of clinical application .
