    <div><p>Purpose</p><p>To investigate the current status of diabetic self-management behavior and the factors influencing this behavior in Chengdu, a typical city in western China.</p><p>Methods</p><p>We performed stratified sampling in 6 urban districts of Chengdu. We used questionnaires concerning self-management knowledge, self-management beliefs, self-management efficacy, social support, and self-management behavior to investigate patients with T2DM from August to November 2011. All of the data were analyzed using the SPSS 17.0 statistical package.</p><p>Results</p><p>We enrolled a total of 364 patients in the present study. The median score of self-management behavior was 111.00, the interquartile range was 100.00–119.00, and the index score was 77.77. Self-management was described as “good” in 46%, “fair” in 45%, and “poor” in 6% of patients. A multiple-factor analysis identified age (OR, 0.43; 95% CI, 0.20–0.91; <i>P</i> = 0.026), education in “foot care” (OR, 0.42; 95% CI, 0.18–0.99; <i>P</i> = 0.048), self-management knowledge (OR, 0.86; 95% CI, 0.80–0.92; <i>P</i><0.001), self-management belief (OR, 0.92; 95% CI, 0.87–0.97; <i>P</i> = 0.002), self-efficacy (OR, 0.93; 95% CI, 0.90–0.96; <i>P</i><0.001), and social support (OR, 0.62; 95% CI, 0.41–0.94; <i>P</i> = 0.023) as positive factors. Negative factors included diabetes duration (5–9 years: OR, 14.82; 95% CI, 1.64–133.73; <i>P</i> = 0.016; and ≥10 years: OR, 10.28; 95% CI, 1.06–99.79; <i>P</i> = 0.045) and hospitalization experience (OR, 2.96; 95% CI, 1.64–5.36; <i>P</i><0.001).</p><p>Conclusion</p><p>We observed good self-management behavior in patients with T2DM in Chengdu. When self-management education is provided, age, education, knowledge, belief, self-efficacy, and social support should be considered to offer more appropriate intervention and to improve patients' behavior.</p></div

    Fluorinated liquid crystals and their mixtures giving polar phases with enhanced low-temperature stability

    No full text
    The fluid ferroelectrics, called ferroelectric nematics (NF), have recently become available by incorporating strong polarity into rod-shaped liquid crystal molecules. Its unprecedented electro-optic properties have created significant excitement in soft matter research. The further progression from the NF phase to the antiferroelectric smectic Z (SmZA) phase, and ultimately to the ferroelectric Smectic A (SmAF) phase, represents a remarkable journey in emerging polar liquid crystal states. Nevertheless, the limitation of NF liquid crystal materials remains one of the prominent obstacles to physical property optimization and optoelectronic device development. In this work, we synthesized a series of fluorinated liquid crystal molecules with large dipole moments and systematically investigated their phase behavior. We designed them with a similar fluorinated aromatic skeleton and varied the structures of the terminal group and bridging bond. We found that the dipole moment density and shape anisotropy significantly affect the phase behavior. Notably, diverse polar liquid crystal phases, including NF, SmZA, and SmAF were observed. Through a multi-component mixing strategy, we successfully achieved a much-expanded temperature window and improved low-temperature stability not only in the NF phase but also in the SmZA and SmAF phases.</p

    Development of Fluorinated Colorless Polyimides of Restricted Dihedral Rotation toward Flexible Substrates with Thermal Robustness

    No full text
    With the rapid expansion of product forms of flexible displays and electronics, the replacement of brittle glass-based substrates with transparent polymer materials is strongly demanded. Colorless polyimides (CPIs) are reckoned as the most promising transparent polymer substrate materials due to their inherent thermal stability, electrical insulation, high transparency, excellent foldability, and proven roll-to-roll processing capability. However, CPIs prepared based on current common strategies have obvious weakness of either transparency or/and thermal/mechanical stability, all of which cannot fulfill the harsh requirements of high-temperature device fabrication. Through great effort, we have developed a series of CPIs based on newly designed highly fluorinated aromatic diamines. The strong electron-withdrawing nature and high bond energy of Ar–F and Ar–CF3 enable a high level of optical transparency while retaining high thermal decomposition stability. This is realized importantly due to the restricted dihedral rotation effect in specific diamines, where multiple –F or –CF3 substitutions effectively restrict the free torsion of benzene rings and create the unique geometrical isomerism. This effect brings the advantages of high glass transition temperatures via increasing the chain rigidity and improved optical transparency due to the breaking of electron conjugation along the chain. Upon further copolymerization optimizations, an excellent synergy ascension in CPI films among high optical transparency, high thermal robustness, and mechanical strength, as well as low thermal expansion, has been achieved, making them promising candidates for new flexible electronics
