Drug delivery systems (DDS) have been developed as a new means of releasing drugs with accurate dosage and convenient administration.It will be promising in clinical application with high effectiveness and safety of drugs, and high compliance of patients.In this review, the status quo and progress of main non-injection routes (oral,trans-dermal and mucosal DDS) are summarized.The application of novel technologies such as targeting, cell micro-encapsulation and micro-fabrication in DDS is introduced.Finally, the problems and some strategy to resolve such problems are addressed.

An experimental investigation on oil air two phase flow through a straight horizontal plexiglass pipe within 40 mm inner diameter was conducted.The superficial velocity ranges of oil and air were 0 05—0 612 m·s -1 and 0 024—50 64 m·s -1 , respectively.The ambient temperature was maintained throughout the experiments.The frictional pressure drop multiplier of two phase flow was expressed using the Lockhart Martinelli parameter correlation in accordance with typical flow pattern, but the modification factor C in the correlations was defined afresh according to flow conditions.New predict correlations for pressure gradient in accordance with typical flow patterns were proposed and the mechanisms of pressure drop production were analyzed for each flow pattern.The proposed models gave good agreement with the experimental data.
