BACKGROUND:Self-assembling peptide scaffolds have attracted much more attention among three dimensional biomaterials due to its biocompatibility, biodegradation, and tailor-made properties.
OBJECTIVE:To review the structure and design of functionalized self-assembling RADA peptide, and the recent advances in the use of RADA self-assembling peptide for three-dimensional cel culture in cel therapy applications.
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.

Objective To analyze the difference of Young's modulus between cirrhotic patients with different etiologies.Methods There were 1 99 patients with decompensated cirrhosis enrolled in this study, all of them had been diagnosed clinically.There were 139 cases of hepatitis B patients with cirrhosis,26 cases of hepatitis C patients with liver cirrhosis,34 cases of patients with alcoholic cirrhosis,and selected 50 healthy volunteers as control group in the same period.All subj ects underwent liver shear wave elastography examination,measured and recorded the Young's modulus,and compared the difference between each groups.Results The Young's modulus of liver in the healthy control group was (4.81±0.9)kPa,which was lowest in all groups.The Young's modulus of hepatitis B cirrhosis,hepatitis C cirrhosis,alcoholic cirrhosis increased successively,which was (16.3±8.9)kPa,(17.8±4.8)kPa,(30.6±12.3)kPa,respectively,and the difference between the groups was statistically significant(F =27.95,P <0.01).Conclusions There were some differences of the Young's modulus of cirrhotic patients with different etiologies by real-time shear wave elastography.

Background and purpose:PTEN mutation has been found in 20%-40% of malignant gliomas.The common mutant epidermal growth factor receptor(EGFR vⅢ)was reported to coexpress in PTEN-deficient EGFR-expressing tumor.PTEN has been shown to interact directly with FAK and reduce its tyrosine phosphorylation levels to inhibit cell invasion.The invasion of glioma cells with EGFRvⅢ expression and PTEN deficiency is increased.This study was to observe whether PTEN inhibits glioma cell invasion even in the presence of strong pro-invasive signals provided by constitutive EGFR activity.Methods:U87?EGFR cells were transfected with pcDNA3.1 constructs encoding PTEN and the cells invasion levels were detected by transwell invasion assay.The expression of FAK was detected by immunoblotting.FAK expression vector was transfected into U87?EGFR-wtPTEN cells and the change of cells invasion was documented.Results:PTEN and PTEN(G129E)could inhibit cell invasion induced by EGFRvⅢ.PTEN and PTEN(G129E)could decrease the FAK phosphorylation at Tyr397.Over expression of FAK in U87?EGFR-PTEN abrogated PTEN-induced down-regulation of the phosphorylation status of FAK and rescued cell invasion.Conclusions:PTEN could inhibit cell invasion induced by EGFRvⅢ by dephosphorylating FAK.

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.
