Variation of nanoparticles in pickering emulsion optimize the physical, control-release and sustained antioxidant properties of hydroxypropyl methylcellulose based microporous film.

The proper encapsulation of liposoluble tea polyphenols (LTP) is expected to better protect oil system. Chitosan hydrochloride-carboxymethyl starch (CHC-CMS) nanoparticles-based Pickering emulsions and hydroxypropyl methylcellulose/sodium citrate (HPMC/SC) microporous film were combined to embed and control-release LTP. With the CHC:CMS ratio varied from 1:0.

Introduction of Curdlan Optimizes the Comprehensive Properties of Methyl Cellulose Films.

The good oxygen barrier and hydrophobic properties of curdlan (CL) film might be suitable complements for MC film, and its similar glucose unit and thermal-gel character might endow the methyl cellulose (MC)/CL blended system with compatibility and good comprehensive properties. Thus, MC/CL blended films were developed. The effects of MC/CL blend ratios on the microstructures and physical properties of the blends were characterized by using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), oxygen and water vapor permeability testing, dynamic mechanical analysis (DMA), light transmittance testing, tensile testing, hydrophilic property testing, and water solubility testing.

[Clinical efficacy and mechanism of total glucosides from white paeony for radioactive liver damage].

To discuss the effects of total glucosides from white paeony on preventing and treating radioactive liver damage, and explore its possible mechanisms. Thirty-six patients with primary hepatic carcinoma from 105th Hospital of Chinese PLA were treated with 3-dimensional conformal radiotherapy and randomly divided into simple irradiation group, total glucosides from white paeony group, and control group. The levels of AST, ALT, HA, LN, PCⅢ, CIV and TGF-β1 in serum of various groups were determined by using ELISA method.
