Objective:To develop and validate the reliability and validity of the care giver assessment via observation (CGAO) in general hospital .Methods:From July 4, 2022 to June 24, 2023, a total of 120 adult inpatients with somatic diseases in Peking Union Medical College Hospital were selected by cluster sampling. All patients completed the CGAO, union physio-psycho-social assessment questionnaire (UPPSAQ-70) and patient health questionnaire-9 item (PHQ-9) assessment simultaneously. Exploratory factor analysis and item response theory analysis were used to explore the structural validity of CGAO by SPSS 26.0 software.The symptoms items and suicide risk assessed by UPPSAQ-70 and PHQ-9 were used as criteria to verify criterion validity.Results:Through exploratory factor analysis, a single-factor model could be constructed. The analysis based on item response theory suggested that it had a good fit with the single-factor stepwise response model ( χ2/ df=1.307, RMSEA=0.051, CFI=0.986, TLI=0.983). The CGAO total score was significantly positively correlated with the total scores of PHQ-9 and UPPSAQ-70 ( r=0.639, 0.518, both P<0.001). The Cronbach's α coefficient of the CGAO full scale was 0.735. Conclusion:CGAO has good reliability and validity in evaluating mental behavior of patients, and is suitable for early recognition of mental behavior abnormalities of inpatients in general hospitals.

Zinc oxide nanowires were hydrothermally synthesized on the surface of an Au cylindrical spiral formed by manually spiraling an Au fiber around an optical fiber core, glucose oxidase was immobilized on these nanowires by physical adsorption, and then a spirally hierarchical structure-based glucose enzymatic electrode was obtained. The surface morphologies of the spirally hierarchical structures and corresponding enzymatic electrodes were extracted, and the electrochemical performances of the enzymatic electrodes were characterized. It was concluded that the synthesizing parameters of zinc oxide nanowires significantly affected the surface morphologies and glucose oxidase immobilization on the spirally hierarchical structures, and further the performances of related glucose sensors. With Zn2﹢concentration of the growth solution set at 25 mmol/L, the roughness of surface morphology was determined to be 0. 10 μm and correlation length 0. 29 μm, resulting in a better immobilization of glucose oxidase upon zinc oxide nanowires. In this case the sensitivity of the glucose sensor was determined to be 2. 15 μA/(mmol/L·cm2), the linear range was 0-4. 50 mmol/L, the low detection limit was 9. 20 μmol/L and Michaelis-Menten constant was 3. 68 mmol/L. The results not only benefit the batch production of the spirally hierarchical structure-based enzymatic electrodes, but also significantly improve the performances of the glucose sensors.
