Objective To observe the effects of a novel HLA-derived peptide, RDP1258, on the human peripheral blood mononuclear cell (PBMC) proliferation to ConA and MLR, and to investigate the mechanisms. Methods Peptide RDP1258 was chemically synthesized. The effects of the peptide on alloreactive cytotoxic activities of human PBMCs were observed using 3HTdR incorporation method. RDP1258, HLA-B2702.75-84, and control peptide were administrated respectively in every experiment. The activity of heme oxygenase-1 (HO-1) was analyzed by the enzymochemical method. Results The results showed that the synthetic HLA-derived peptide could obviously inhibit the proliferation of human PBMCs and inhibited HO activity in a dose-dependent manner in vitro. Conclusion HO-1 might participate in the inhibitory effect of RDP1258 on the proliferation of human PBMCs induced by mitogen and isoantigen.

Pulse-taking, as one of the four diagnostic methods of inspection, auscultation and olfaction, inquiry and pulse-taking, can fully embodies the characteristics of traditional Chinese medicine. Pulse-taking is the teaching key point for the international students. However, because the pulsetheory and literature is quite profound and abstract and there is a long distance between the class teaching and clinical practice, the teaching of pulse-taking is also the difficult point for the international students. Therefore, the pulse-taking teaching should focus on the interesting teaching, the culture of traditional Chinese medicine of pulse, image teaching and practice training.
