Research Interests
Design and development of targeting drug delivery system and novel drug preparations and dosage forms. Of particular interest are three areas namely, i) water-soluble polymer-drug conjugates for targeted cancer therapy, ii) Duodenum-specifec drug delivery system and iii) Study of protein- loaded nanoparticles for oral drug delivery.

1. Tumor-targeting HPMA copolymer-anticancer conjugates
The purpose of this study is to investigate the potential of HPMA copolymer-drug conjugates for enhancing the targeting efficiency to tumor. Here we investigate the synthesis of N- (2-hydroxypropyl) methacrylamide copolymer-anticancer drug conjugates (HPMA–D), characterization of their physicochemical properties, stability in vitro. Based on above results, cytotoxicity and subcellular fate of copolymer in in vitro tumor cells, biodistribution in vivo, tumor targeting efficiency and pharmacokinetics in tumor-bearing animals are furtherly investigated.This research will potentially enhance efficacy of anti-cancer drug and minimize their toxicity, also will provide new method for cancer chemotheropy.
The research is supported by National Natural Science Foundation (30500636) of the People’s Republic of China.
2. Duodenum-specifec drug delivery system
The duodenal ulcer is quite prevalent among duodenal diseases. It takes a long time to be treated using common formulations or by administration routes, but the results are still in low efficiency, which is due to the specific structure and physiological characteristics of the duodenum. In this study, the drug-loaded microspheres are prepared using thiolated-chitosan as carrier material which is mucoadhensive in the acidic environment. A pH-sensitive polymer (2.9-4.0) as coating material is used based on the differences of the pH values between the pathological region and the other areas of G.I tract. A multiple targeting oral microspheres system for the duodenal ulcer’s treatment is constructed based bioadhensive and pH-sensitive mechanisms. The in vitro drug release, antibacterial mechanism, biodistribution in GI tract, pharmacokinetics, pharmacodynamics and toxicity are systematically investigated to explore the feasibility of this multiple targeting system and its deficiencies. The duodenum-specific drug delivery system with prolongation of the residence time of the drug in the ulcer region may be of great help for the segmental treatment of gastrointestinal diseases and the absorption studies of drugs. The duodenum-specific drug delivery system has not been reported elsewhere.
The research was supported by National Natural Science Foundation (30772667) of the People’s Republic of China.
3. Study of protein-loaded nanoparticles for oral drug delivery, supported by National key Tech project.
