Chinese Journal of Tissue Engineering Research 2014;(12):1907-1913
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. 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 establish animal model on the basis of the autoimmune etiology for a subset of cases of Tourette syndrome.Methods:Blood samples were drawn from patients with TS(by DSM-IV)and were sent for further enzyme-linked immunosorbent assays(ELISA)to a laboratory.Eight serum samples with the highest concentration of anti-neural antibody were selected for TS model group,and 8 serum sampled with the lowest concentration of anti-neural antibody were selected for the control group.Osmotic mini pump filled with undiluted TS or control serum were microinfused into the rat striatum at a rate of 0.5 μl /h for 72 h.Stereotypic movements were recorded at 1 d,7 d,14 d and 21 d after microinfusion.Several categories of stereotypy including bites(teeth touching the cage,wood chips,vacuous chewing or other objects except the body),taffy pulling(raises of the forepaw to the mouth and face),self-gnawing,licking not associated with grooming,grooming,head shaking,paw shaking,rearing and episodic utterances(EU)were recorded.Results:The anti-neural antibody serum concentration used for TS model was(0.29±0.06) U/L,and that used in control group was (0.10±0.04) U/L.After infusion of TS sera,stereotypic behaviors in rats was increased significantly[(37.2±7.1) vs.(106.3±11.7),P=0.000].Significant difference were observed in stereotypies scores of TS rats compared to control rats after microinfusion[(106.3±11.7) vs.(31.2±6.2),P=0.000].Conclusion:Stereotypic behaviors are increased in rats after intrastriatal microinfusion of Tourette Syndrome sera under noninflammatory conditions.

Objective To evaluate the clinical effect and safety of intravenous administration of phloroglucinol combined with delivery of ball-assisted free position in parturient women during labor.Methods One hundred and fifty-two primiparous women who were treated by vaginal delivery from June 2015 to August 2016 in Beijing Navy General Hospital were selected as the study subjects.They were given 80 mg of phloroglucinol diluted in saline injection intravenous injection.Observation group were treated with childbirth.Control group treated with traditional supine or lateral body.Results The rate of descending of the observed group was longer than that of the control group((1.09±0.22) cm/h vs.(0.83±0.15) cm/h),the first labor time,the second labor time and the total labor time of the observation group were shorter than the control group((9.57±1.71) h vs.(12.13±2.64) h,(35.75±8.68) min vs.(61.21±10.03) min,(11.34±1.96) h vs.(14.66±2.70) h),the difference between the two groups was statistically significant(t=3.611,4.204,3.307,3.456,P<0.05).While the third labor time of the control group and the observation group were (8.43±1.12) min and (7.92±0.96) min,the difference between the two groups was not statistically significant(t=1.005,P>0.05).The percentage of vaginal delivery in the observation group was 89.47%(68/76),significantly higher than that in the control group(73.68%(56/76)),the difference was statistically significant(χ2=4.514,P<0.05).The incidence of vaginal midwifery was 1.32%(1/76) and that of cesarean section was 9.21%(7/76) of observation group,significantly lower than that in control group(5.26%(4/76),21.05% (16/76)),the difference was statistically significant(χ2=5.323,4.376,P<0.05).Observation group 24 h postpartum hemorrhage was (273.12±58.23) ml,significantly less than the control group((385.42±70.13) ml),the difference between the two groups was statistically significant(t=3.744,P<0.05).The observation group had postpartum hemorrhage of 1.32%(1/76),urinary retention of 2.63%(2/76),and the percentage of neonatal asphyxia of 2.63%(2/76),were lower than that of the control group(5.26%(4/76),10.53%(8/76),9.21%(7/76)),the difference between the two groups was statistically significant(χ2=4.103,4.925,4.421,P<0.05).Conclusion The delivery of ball-assisted free-body delivery in active stage of delivery can promote natural childbirth.The medical staff should update the concept of delivery and raise awareness to encourage the use of phloroglucinol combined with free-body delivery.

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.

Objective To explore the application effects of PDCA circulation on behavior management in discharged patients with first cerebral infarction. Methods Patients with first attack of cerebral infarction were enrolled from the department of neurology of the First Hospital of Anhui Medical University from April 2013 to March 2015. According to their admission numbers, patients were divided into the observation group (94 cases) and the control group (80 cases). Besides of the regular personalized secondary prevention, the observation group was also applied for the PDCA cycle for nine months. Stroke Behavior Change Inventory was used to evaluate the changes of their lifestyle and medication compliance one year after discharge for two groups. Results After the observed patients were discharged one year, the changed extent of these five behaviors including quitting smoking, regular monitoring blood pressure and sugar, appropriate exercise, pressure control in the observation group were 0.00 (0.00, 3.00), 1.68 (1.00, 3.00), 1.00 (0.00, 2.00), 1.20 (0.75, 2.00), 1.00 (0.00, 1.00) points, and these in the control group were 0.00 (0.00, 1.0)0, 1.00 (0.00, 2.00), 0.00 (0.00, 1.00), 1.00 (1.00, 2.00), 0.00(0.00, 1.00) points. The observation group in these parameters had significantly higher than the control group (Z=-3.166--2.419, P < 0.05). The changed extent of these behaviors in the medication compliance such as reducing blood glucose, blood pressure, atrial fibrillation, cardiovascular disease, and stroke prevention in the observed group were 0.00 (0.00, 0.00), 0.00 (0.00, 2.00), 0.00 (0.00, 0.00), 0.00 (0.00, 0.00), 3.00 (3.00, 3.00) points, and these in the control group were 0.00 (0.00, 0.00), 0.00 (0.00, 0.79), 0.00 (0.00, 0.00), 0.00 (0.00, 0.80), 0.00 (0.00, 1.50) points. The observation group in these parameters had significantly higher the above parameters than the control group (Z=-8.081--2.595, P<0.05). Conclusions Application of the PDCA circulation in the patients with first attack of cerebral infarction after their discharge can help them correct lifestyle and increase their medical treatment compliance, which is beneficial for secondary prevention of cerebral infarction.
