Methods Exotoxin A gene was amplified from the recombinant plasmid pSK/PEA-T vector and subcloned into the pMAL-P2X vector. Then the recombinant plasmid pMAL- PEA was transformed to E.coli BL21. After induction with IPTG, the expressed protein was analyzed by SDS-PAGE and purified with affinity chromatography. Results The recombinants expressed the fusion protein at a level of about 20% of total cell proteins, and 80% of the fusion protein was secreted into the supernatant. Conclusion Successful expression and purification of PEA are of significance for in-depth study of the pathogenic mechanism of Pseudomonas aeruginosa and preparing immunotoxin.

ObjectiveTo explore the causes and countermeasures for extravasation of intravenous fluids in children. Methods726 cases of intravenous infusion in pediatric surgery department from May to December 2011 in our hospital were observed. ResultsThere were 30 cases with extravasation of intravenous infusion in the 726 cases,the leakage rate was 4.13％.The specific causes of fluid extravasation included:younger age of children,not cooperating with the infusion in 18 cases,accounting for 60.00％,followed by non standardized fixation methods in 5 cases,accounting for 16.67％,and accompanying family members refused to be disturbed accounted for 13.33％,Nursing visits to owe in a timely manner accounted for 6.67％.The rate of younger age of children and lack of cooperation leading to fluid extravasation were significantly higher than other causes,the difference was statistically significant. ConclusionsChildren age,fixation method,cooperation of family members,inspections and other factors can be controlled.Along with the continuous improvement of medical standards and a variety of active and effective implementation of the measures,these factors can be controlled effectively.Strengthening the training of nurses and vocational skills to enhance their own sense of responsibility,to give standardized infusion operation and fixation,and give predictable observation and treatment,can effectively prevent the occurrence of extravasation of intravenous fluids.

Objective To investigate the effect of rosiglitazone on the epithelial-mesenchymal transition process of renal tubular epithelial cell induced by transforming growth factor-β(TGF-β). Methods The human renal tubular epithelial cell line HK-2 was cultured in vitro and treated with TGF-β at the presence or absence of rosiglitazone, and the morphological changes of HK-2 cells were observed. Then PPARγ,SMAD family number 2/ 3,E-cadherin and Vimentin were detected by western blot, and the mRNA expression of PPARγ, E-cadherin, Vimentin, zinc finger transcription factor Snail and Slug were measured by realtime quantitative PCR. Finally,dual luciferase reporter assay was performed to detect the effect of TGF-β and rosiglitazone on the tran-scription activity of E-cadherin promoter. Results TGF-β could induce the EMT process of HK-2, including morphological changes such as longer pseudopod and broader cell space. TGF-β also activated the SMAD2/ 3 signaling pathway, with expression changes of E-cadherin and Vimentin. Rosiglitazone reversed the morphological changes of HK-2 cells induced by TGF-β, with shor-ter pseudopod and narrower cell space. Rosiglitazone also inhibited the mRNA and protein expressions of Vimentin, and restored the mRNA and protein expression of E-cadherin by up-regulating PPARγ. The activity of E-cadherin promoter was enhanced under the treatment of rosiglitazone. Conclusion Rosiglitazone can antagonize the EMT process of renal tubular epithelial cell induced by TGF-β, through the activation of PPARγ and stimulating transcription and protein expression of E-cadherin.

Objective Development of eyeball is visually regulated by messengers that released from the retina, and research demonstrated that retinoic acid (RA) is the only extrinsic biochemical candidate that could act as a growth controller. Present study was designed to evaluate the RA system in retina of guinea pig eye with experimental form deprivation myopia. Methods The form deprivation myopia models were monocularly established in the 24 2-week-old guinea pigs by occluding the lateral eyes using white translucent hemispheres for two weeks, and the fellow eyes were as normal control. Refraction diopter was detected with streak retinoscopy after cycloplegia, and axial length and vitreous depth were calculated with Cinescan A/B ultrasonography before and 2 weeks after experiment. All animals were sacrificed and retina was dissected 2 weeks after experiment. The RA level in retina was delected by High Performance Liquid Chromatography (HPLC). The expressions of RA-binding proteins Ⅰ(CRABP-Ⅰ) and RA receptor-β(RAR-β) protein and mRNA were assayed by Western-blotting and Real-time PCR, respectively. The experiment and use of animals followed the Standard of Association for Research in Vision and Ophthalmology. Results The spherical equivalent refraction was (+ 3. 00 ± 0. 75) D in the model group and (+ 2. 88 ± 0. 67) D in control eyes (t= 0. 672, P ＞ 0. 05), the ocular axial length was (7. 822 ± 0. 083) mm in model group and (7. 791 ±0.073) mm in control eyes before experiment (t = 0. 346, P ＞ 0. 05). In 2 weeks after experiment, the spherical equivalent refraction was (- 3. 82 ± 0. 13) D versus (1. 99 ± 0. 58) D and axial length was (8. 346 ± 0. 047) mm versus (7. 888 ± 0. 042) mm between model eyes and control eyes (t = 8. 376, P ＜ 0. 001; t = 3. 343, P ＜0. 05). No significant difference in the level of RA in retina before and after experiment (1. 394 ±0. 079 μg/g vs 1. 295 ±0. 023 μg/g) (t =0. 897, P ＞0. 05) but obviously elevated after experiment in model eyes compared with control eyes (2. 356 ± 0.098 μg/g vs 1.499 ±0.035 μg/g) (t =4. 934, P ＜0. 01). The expression of CRABP-Ⅰ and RAR-β mirrored these directional changes. Conclusion The RA system in retina is upregulated in the eye of guinea pig with form deprivation myopia. This findings suggests that RA may act as a messenger in the development of experimental myopia.
