OBJECTIVE To study the proteome of inferior colliculus and determinate the region-typical proteins which may be the candidate cause of the Central Auditory Processing Disorders. METHODS The telencephalon was taken as reference, and then identified and quantified the proteome of IC of adult rats with iTRAQ. Those with higher abundance in inferior colliculus than the other three regions were considered as IC-Region typical proteins,which may lead to functional specializations. RESULTS We identified 1937 cytomembrane proteins in total, among which there are 53 IC-Region typical proteins, which may lead to functional specializations of inferior colliculus.We used GO and KEGG pathway to analyze these proteins and then found that these proteins mainly take part in the regulation of neurons development and information integrations. CONCLUSION Our quantitative comparison of inferior colliculus has revealed two candidate proteins, including CaMKII and SV2A, which may play important roles in maintaining the balance of excitatory and inhibitory transmitters release. These proteins may be the candidate proteins for Central Auditory Processing Disorders.

Objective To investigate the effect of AP-2α on the chemoresistance to oxaliplatin of colorectal carcinoma cell and its related mechanism.Methods Plasmid of GV102-AP-2α-RNAi (experimental group) and control plasmid GV102-NC (negative control group) were transfected into HCT-116 using Lipofectamine 2000 respectively.The AP-2α expression levels of mRNA and protein of experimental group,control group and HCT-116 blank group were detected by qRT-PCR and Western blot.Cell proliferation assay was performed using the CCK-8 and the apoptosis assays were preformed with Annexin V-PE Apoptosis Kit.Results The AP-2α expression levels of mRNA and protein both decreased after transfection of AP-2α-RNAi plasmid,moreover,the effect produced by subsequence 1 was the most significant.After treatment by oxaliplatin,AP-2α protein levels increased with time while mRNA did not change significantly.Western blot results suggested that the level of AP-2α protein in experimental group which was maintained in oxaliplatin was lower than the negative control group.CCK-8 results suggested that cell proliferation ability was significantly higher for the experimental group maintained in oxaliplatin [(88±3) ％] than the negative control group maintained in oxaliplatin [(57±3) ％] and the blank group maintained in oxaliplatin [(73t4) ％].Flow cytometry showed that the apoptosis rate of the experimental group maintained in oxaliplatin [(15.07±1.20) ％] was lower than the control group maintained in oxaliplatin [(24.93±0.90) ％] and the blank group maintained in oxaliplatin [(23.71±1.32) ％].Conclusion AP-2α may be related to the sensitivity of colon cancer cells to oxaliplatin.

BACKGROUND: The study of tissue-engineered cartilage with predetermined shaping and regeneration has provided novel ideas and techniques for repair of laryngeal cartilage erosion; however, due to the special natures of the morphology, location and function of laryngeal cartilage, tissue engineering research has not, to date, exhibited its ful advantages in the reconstruction of laryngeal cartilage. OBJECTIVE:To explore the feasibility of building tissue-engineered larynx-shaped cartilage using poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHH) as a scaffold filed and encapsulated with pedicled myofascial flaps. METHODS:Porous PHBHH was prepared and formed into a holow like larynx-shape, and the cel PHBHH composites were cultured for 1 weekin vitro prior to implantationin vivo. The cel-PHBHH composite was filed and encapsulated with myofascial flaps with the pedicle forin situ implantation in nine rabbits as experimental group. PHBHH scaffold with no chondrocytes was implanted alone in three rabbits as control group. Cartilage regeneration was assessed at 6, 12 and 18 weeks after surgery through morphological observation, histological and immunohistochemical detection. RESULTS AND CONCLUSION: In the experimental group, the shape and porosity (> 90%) of the material were ideal, the cels exhibited good adhesion with the material and the blood supply within the myofascial flap with pedicle was rich for effective filing and encapsulation of the cel PHBHH composite. Tissue-engineered laryngeal cartilage with the holow, semi-trumpet shape was idealy formed at 6 weeks after the surgery. Further maturation of the cartilage was observed at 12 and 18 weeks after the surgery. However, there was no cartilage tissue in the control group. This study shows that PHBHH is a suitable material for the formation of a holow, semi-trumpet shape with good celular compatibility. Myofascial flap filing and encapsulating can be used to build tissue-engineered laryngeal cartilage with a holow, semi-trumpet shape.

Objective To evaluate the effectiveness of training management applying character color theory in patients with peritoneal dialysis on the compliance and dialysis effect. Methods Of 95 patients undergoing catherization for peritoneal dialysis from January 2013 to May 2014 in the peritoneal dialysis center,72 patients accepted character color psychological questionnaire designed by Le Jia for character color analysis.72 patients were divided into matched control group and experimental group according to their choice with red, yellow, blue, green character color, 36 cases in each group. The control group adopted the traditional training way of accepting 7 days′training course teached by the professional nursers,one follow- up management each month. According to the difference of character color,the experimental group were given different education training courses, interactive learning, and follow- up time. After 6 months′follow- up, the two groups adopted peritoneal dialysis self management behavior questionnaire designed by Liu Pengfeng and self- efficacy scale designed by education research center for chronic disease in Amercian Stanford University. The score of self management ability and self- efficacy and the change of load capacity, blood pressure, dialysis adequacy and biochemical indicators of the two groups were analyzed. Results In the control group and experimental group,the score of self management ability and self- efficacy and the level of dialysis adequacy were statistically significant, respectively, (5.64±1.57) points vs. (6.75±1.32) points;(5.22±1.48) points vs. (6.69±1.43) points; 1.64±1.64 vs 1.85±0.13.Z and P values were respectively -2.969, -3.828, -6.361, and 0.003, 0.000, 0.000.Edema happened in the control group was 24 cases, and 11 cases in the experimental group. P and χ2 values were 0.013 and 10.017.Systolic blood pressure and di-astolic blood pressure were respectively (147.78±15.69) mmHg (1 mmHg=0.133 kPa) vs.(135.39±9.01) mmHg,(95.86±7.50) mmHg vs. (83.94±7.46) mmHg in the two groups. Z and P values were respectively -3.843, -5.666, and 0.000, 0.000.There was significant difference between the experimental group and control group. Conclusion The education and training applying character color feature in patients with peri-toneal dialysis can mobilize the initiative of self management, improve the patients' self- care competency and self-efficacy, enhance patients′compliance, that can improve the effect of peritoneal dialysis.

BACKGROUND:A great development has been achieved in essential research on tissue engineered cartilage. However, its real application in otolaryngology has been rarely reported. It is faced with the topic to explore the simple and convenient method of repairing laryngeal cartilage by tissue engineering technique. OBJECTIVE:To compare the effect of porous spongy poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) seeded with chondrocytes or using senior tissue engineered cartilage in repairing al ogenic thyroid cartilage defects.METHODS:Chondrocytes at passage 3 were harvested from infant rabbits within 3 days. Porous spongy poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) seeded with chondrocytes composites were made by tissue engineering technique. The chondrocyte-poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) composites were co-cultured in vitro to form junior tissue engineered cartilage. And then respectively used for repairing the thyroid cartilage defects and directly transplanted with junior tissue engineered cartilage (experimental group A, n=5), or firstly the junior tissue engineered cartilage to be implanted subcutaneously for a period of time to further maturity for relative senior tissue engineered cartilage and secondly to be transplanted (experimental group B, n=5) into adult New Zealand white rabbits. Simple poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) sponge scaffold (control group A, n=4) and chondrocyte suspensions(control group B, n=4) were used as reparative materials in defect areas as control groups. Final y, the reparative effect was respectively studied grossly and histological y at 4 weeks (experimental group B) and 8 weeks (experimental group A, control group A and control group B) after transplantation. RESULTS AND CONCLUSION:The cartilage defects were wel repaired in the experimental groups. It was smooth between the reparative area and original cartilage without dents and defects. Both were similar grossly. But few chondrocytes at interfacial region between the reparative area and original cartilage and poor matrices were observed in the experimental group A. A Few chondrocytes and more matrices were observed in the experimental group B. Inflammatory cellinfiltration was not obvious in two experimental groups. Control groups showed soft tissue of dark-red color accompanied with local concave in gross specimens. Histological examination and special staining showed there were no cartilage-like structure and secretion of matrix components. The results showed that it is possible to repair thyroid cartilage defect using junior tissue engineered cartilage directly or junior tissue engineered cartilage after in vitro implantation in al ograft rabbits with immunity, and the immunoreaction is not obvious;in the same period, the repairing effect of mature tissue engineered cartilage is better than that of junior tissue engineered cartilage. However, application of junior tissue engineered cartilage directly can save time, costs, workload and operational link, and avoid the pain from secondary skin surgery, which is one of the more practical approaches.
