Development and evaluation of short-form version of the Constitution in Chinese Medicine Questionnaire: study a new and best brief instrument of Chinese medicine for health management.

Background: More efficient instruments for body constitution identification are needed for clinical practice. We aimed to develop the short-form version of the Constitution in Chinese Medicine Questionnaire (CCMQ) and evaluate for health management.

Methods: First, the short forms were developed through expert survey, classical test theory (CTT), and modern item response (IRT) based on the CCMQ.

Preparation of Amine-Modified Polyacrylonitrile Fibers: Copper Removalin Aqueous Solution.

In this study, Polyacrylonitrile (PAN) fibers were prepared by a simple and effective electrospinning method. Subsequently, the PAN fibers were modified by diethylenetriamine (DETA) to produce aminated polyacrylonitrile (APAN) fibers. Finally, the adsorbability of copper ions on the surface of the fibers was examined in an aqueous solution.
