METHODS:Total 224 literatures related to self-assembling peptide and tissue engineering from PubMed, Web of Science and CNKI databases were screened out for this review. The keywords were“self-assembly peptide, tissue engineering”in English and Chinese, respectively. Final y 48 of 224 articles about the design, fictionalization, and three-dimensional cel culture of peptide scaffolds were included in this review.
RESULTS AND CONCLUSION:Self-assembling peptide could undergo spontaneous assembly into wel-ordered interwoven nanofibers in water and rapidly form hydrogel, which physical y mimics the architecture of natural extracel ular matrix to ensure a real three-dimensional microenvironment for cel s. In terms of bio-function, this material can be tailor-made with various bioactive short peptide motifs to promote cel adhesion, proliferation, and differentiation.

Objective To observe the effect of Huangqi Danshen Drop Pill(HDDP) on pituitary (Pit) induced acute myocardium ischemia. Methods Acute myocardium ischemia rat model was established by sublingual venous injection of Pit(0. 35U/kg). The changes of the T wave ( II channel ECG) and serum contents of lactate dehydrogenase (LDH), CK, superoxide dismutase (SOD) and malondialdehyde (MDA) were observed in various times after Pit injection. Results HDDP could significantly lower the height of T waves, increase SOD activity and decrease MDA content. Conclusion HDDP can improve acute myocardium ischemia induced by Pit.

Purpose To propose a novel compression method for region of interest (ROI) based on Curvelet transform and SPIHT algorithm. Materials and Methods The ROI was firstly extracted without compression, and Curvelet transform was applied for the background regions. The Curvelet coefifcients were coded using SPIHT algorithm. Then the images after compression are obtained by inverse Curvelet transform. The ROI and the background were ifnally overlapped to get the full compressed image. Effect of ROI compression and overall compression were compared, as well as the Curvelet transform and wavelet transform, based on peak signal noise ratio. Results The ROI compression highlighted the region of interest and the visual effect was superior to the overall compression. The peak signal to noise of Curvelet transform was higher than that of wavelet transforms, and the compressed images were more clear for the same proportion. Conclusion ROI compression based on Curvelet transform and SPIHT algorithm can achieve efficient compression images without losing important diagnostic information, which complies with the requirement of high precision and high quality of medical image compression.
