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.

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 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.

Objective To investigate the efficacy and influence factors of hysteroscopic guiding endometrial resection on dysfunctional uterine bleeding.Methods One hundred and eighty women with dysfunctional uterine bleeding were selected as our subjects in Maternal and Child Health Hospital of Qinhuangdao from Jan.2009 to Jan.2011.One hundred and fifty which meet with operation indications underwent hysteroscopic guiding endometrial resection.Operation periods,blood loss,adverse effects rate were recorded.Serum follicle stimulating hormone (FSH),luteinizing hormone (LH),estradiol (E2) and progesterone (P) hormone levels were detected at preoperative and postoperative.The efficacy was recorded at 6 and 12 months after the procedure.Results The average operation time and amount of bleeding were (31.2 ± 11.0)min and (32.3 ± 10.5) ml,and no blood transfusion performed during the operation.All cases got the succeed operation.There were no significant difference in terms of serum FSH,LH,E2 and P concentrations before and after treatment(P ＞0.05).At 6 months after treatment,improvement rate was 64.0％ (96/150),and effective rate was 32.0％ (48/150).The total effective rate was 96.0％ (144/150).At 12 months after treatment,the improvement rate was 58.0％ (87/150),effective rate was 36.0％ (54/150).The total effective rate was 94.0％(141/150).There was significant different in terms of total effective rate between 6 months and 12 months after treatment(x2 =113.6,P ＞ 0.05).Postoperative complications occurred in 2 cases,including 1 cases of abdominal pain,and 1 cases of dysmenorrhea.Uterine cavity depth,age and disease duration were the main factors affect the clinical efficacy.(OR(95 ％ CI):-1.14 (-1.17 to-1.07),1.60 (1.31 to 2.08),-1.02(-1.14 to-1.08),P ＜ 0.05).Conclusion Treatment of hysteroscopic guiding endometrial resection on dysfunctional uterine bleeding is proved to be efficacy due to the less adverse reaction.

Objective To investigate the relationship between serum CC10 protein and lung injury induced by mechanical ventilation.Methods Forty healthy Wistar rats of both sexes weighing 200-250 g were randomly divided into 5 groups(n=8 each):group Ⅰ control;group Ⅱ mild lung injury[VT=7 ml/kg,duration of mechanical ventilation(t):2 h];group Ⅲ moderate lung injury(VT=7 ml/kg,t=4 h);group Ⅳ severe lung injury(VT=40 ml/kg,t=2 h);group Ⅴ extremely severe lung injury(VT=40 ml/kg,t=4 h).The animals were anesthetized with intraperitoneal 10% chloral hyrdrate 3.5 ml/kg and tracheostomized.Group Ⅰ received no mechanical ventilation.The animals in group Ⅱ-Ⅴ were mechanically ventilated with air(FiO2=21%,RR=40 bpm,I:E=1:2).The animals were sacrificed at the end of mechanical ventilation.The lungs were immediately removed for microscopic examination and determination of W/D lung weight ratio.The left lung was lavaged.The CC10 protein level in broncho-alveolar lavage fluid(BALF)and serum were determined by Western blotting.The Clara cells in the bronchiolar epithelium were examined by immno-histochemistry.Results The level of CC10 protein in BALF was significantly lower in group Ⅳ and Ⅴ while the serum CC10 protein level was significantly higher in group Ⅱ-Ⅴ than in group Ⅰ.The serum CC10 protein level was positively correlated while the CC10 protein level in BALF was negatively correlated with the severity of lung injury and W/D ratio.Conclusion The serum CC10 protein is closely related to the severity of lung injury induced by mechanical ventilation.

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.
