[Study on preparation and characterization of resveratrol solid lipid nanoparticles and its anticancer effects in vitro].

Objective: To prepare resveratrol solid lipid nanoparticles (Res-SLN) and investigate its physical and chemical speciality and anticancer effects in vitro.

Methods: Res-SLN was prepared by the solvent emulsification-evaporation method. Its morphology, particle size and zata potential were examined by transmission electron microscope and laser granularity equipment.

[The application of palynology in forensic medicine].

Palynology, one science of plant's pollen and spores, has been proven to be a new frontier discipline. Because of the characteristics of pollen and spores, such as small size, light weight, large amount, and difficult to be found, they can leave physical evidence and provide new clues to solve a case. Therefore palynology has a good prospect for practical application in forensic medicine.

[Preparation of alpha-hydrocycholic-beta-cyclodextrin inclusion compound].

Objective: To study the preparation of alpha-Hydrocycholic-beta-Cyclodextrin inclusion compound.

Methods: It was studied with orthogonal design to analysis three factors of inclusion rate such as the weight ratio between HDCA and beta-Cyclodextrin, the temperature and the reaction time. Fourier transform infrared spectroscopy, scanning electron microscopy, taste and solubility test were used to identify the inclusion compound.
