Background: The public’s cognition of stroke and responses to stroke symptoms are important to prevent complications and decrease the mortality when stroke occurs. The aim of study was to develop and validate the Chinese version of the Stroke Action Test (C-STAT) in a Chinese population.Methods: This study was rigorously implemented with the published guideline for the translation, adaptation and validation of instruments for the cross-cultural use in healthcare care research. A cross-sectional study was performed among 328 stroke patients and family members in the Department of Neurology in the Second Hospital of Lanzhou University, Gansu province, China in 2014.Results: The Chinese version of the instrument showed favorable content equivalence with the source version. Values of Cronbach’s alpha and test-retest reliability of the C-STAT were 0.88 and 0.86, respectively. Principal component analysis supported four-factor solutions of the C-STAT. Criterion-related validity showed that the C-STAT was a significant predictor of the 7-item stroke symptom scores (R = 0.77; t = 21.74, P< 0.001).Conclusion: The C-STAT is an intelligible and brief psychometrical tool to assess individuals’ knowledge of the appropriate responses to stroke symptoms in Chinese populations. It could also be used by health care providers to assess educational programs on stroke prevention.

Cobalt and manganese oxides ((Co, Mn)3O4) nanowires freely standing on nickel foam are prepared by a simple template-free growth process and heat treatment. The results show that the (Co, Mn)3O4 composite forms a uniform film and densely covers the nickel foam substrate. The film is composed of nanowires with a diameter up to around 30-40 nm. The electrochemical capacitance behavior of the self-supported binderless nanowires electrode is investigated by cyclic voltammetry, galvanostatic charge/discharge test and electrochemical impedance spectroscopy. The (Co, Mn)3O4/Ni-foam electrode exhibits a high specific capacitance of 611 F g-1 at a charge/discharge current density of 2.38 A g-1 in 6.0 mol dm-3 KOH electrolyte. Furthermore, the (Co, Mn)3O4/Ni-foam electrode delivers a high energy density 13.6 Wh kg-1, and even a high power density of 5.68 kW kg-1. More importantly, the specific capacitance retention is 95% after 2000 charge/discharge cycles at 2.38 A g-1 and with columbic efficiency higher than 98%. This work suggests that the as-prepared (Co, Mn)3O4/Ni-foam electrode has potential application in electrochemical capacitors. [ABSTRACT FROM AUTHOR]
