BackgroundAlong with three years implementation of health reform in China, this study aimed at providing the up-to-date evidence about the accessibility of essential public health services (EPHS) among adults with chronic diseases (CDs) in both urban and rural areas, as well as determinants in access to EPHS.MethodsThe data were collected from a cross-sectional survey conducted in 2013, which used a multistage stratified random sampling method to select 54 urban communities and 54 rural villages. Hypertension patients and diabetes patients were the target population who are the main beneficiaries of EPHS. Single factor analysis of influencing factors on difference access to EPHS was performed by Chi-Square analysis. Logistic regression analysis was used to determine the predictors of effective management and effective control.ResultsPatients with hypertension or diabetes were predominantly middle-aged or older persons and had a mean age of 65.26 year. People with CDs in China have a higher basic accessibility rate in EPHS with more than 90% of them having experience in receiving EPHS. And those who are willing to receive services from doctors have the most positive influence on effective management and control in blood pressure or blood glucose. But unsatisfied quality and equity of EPHS still exist in primary health system. 90% of participants could receive EPHS, but just 44% of them could control their diseases effectively. And participants from cities had the higher rates in effective management (urban: rural = 57%: 50.6%) and effective control (urban: rural = 39.5%: 27.8%).ConclusionPeople with CDs have a high level in geography and economic accessibility to EPHS, but the effectiveness of health management also needs to be improved, especially for those living in rural areas. Our study highlights the continuing need for improving ability to provide EPHS and the equality among regions. Meanwhile, strengthen health education and promotion for patients with CDs to improve their willingness to receive EPHS is also highlighted.

Blend films were prepared by blending 7 wt % konjac glucomannan (KGM) aqueous solution with 2 wt % chitosan (CH) in acetate solution and dried at 40°C for 4 h to obtain the transparent films. Their structure and properties were studied by infrared (IR), wide-angle X-ray diffraction (WAXD), scanning electron microscopy (SEM), thermogravimetric analysis (TGA), and differential thermal analysis (DTA). Crystallinities of the blend films decreased with the increase of konjac glucomannan. The thermostability, tensile strength, and breaking elongation of the blend films in dry state were obviously higher than those of both konjac glucomannan and chitosan films. Tensile strength of the dry blend film achieved 73.0MPa when the weight ratio of chitosan to konjac glucomannan was 7:3. The structure analysis indicated that there is a strong interaction between konjac glucomannan and chitosan resulted from intermolecular hydrogen bonds. The water solubility of the blend films was improved by blending with konjac glucomannan, so they have promising applications to soluble antiseptic coating of pills.

The transformation of PVDF from α-phase to β-phase makes PVDF more polar and decreases the crystallinity of PVDF.
