Since partial differential equations were used to describe biological regulations and phenomena, many scholars and specialists have been paying more attention to PDE and many new subjects have been established which have more reality backgrounds, one of which is chemostat model.

自从偏微分方程被用来描述生物学中许多生物规律和现象以来，一直吸引着大量的专家和学者的注意力，并形成了许多具有很强实际背景的新模型，chemostat模型就是其中之一。

The one carbon unit transfer reaction involving in the tetrahydrofolate coenzymes has caused great interest which is very important in the living system and has played an important role in the designing and syntheses compounds (especially the anti-cancer and LCD materials). In our study it was found that benzimidazolium salt has the ability to transfer one or two one-carbon unit and is a kind of new tetrahydrofolate coenzymes model. This research provides new method for biomimetic synthesis.

Highly active, small-molecule furin inhibitors are attractive drug candidates to fend off bacterial exotoxins and viral infection. Based on the 22-residue, active Lys fragment of the mung bean trypsin inhibitor, a series of furin inhibitors were designed and synthesized, and their inhibitory activity toward furin and kexin was evaluated using enzyme kinetic analysis. The most potent inhibitor, containing 16 amino acid residues with a Ki value of 2.45×10~(-9) M for furin and of 5.60×10~(-7) M for kexin, was designed by three incremental approaches.
