BackgroundPterygia is a clinical common disease.A lot of surgical methods are developed to decrease the recurrence rate.Resent years,the application of fibrin glue is receiving more and more attention.Objective This study was to explore the effects of fibrin glue in decreasing inflammatory irritation and its mechanism. Methods Pterygia models were created in 12 clean rabbits by exsection of limbal tissue and topical administration of 1.25% diluted hydrochloric acid,and then the conjunctival autograft surgery was performed in the experimental rabbits.The conjunctival flap was sutured in the left eyes,and the conjunctival wound was closed using fibrin glue in the right eyes.The operation duration for each group was documented and compared.The irritation sign was examined under the slit lamp in all the rabbits 1 week and 4 weeks respectively.The expressions of vascular endothelial growth factor (VFGF) and basic fibroblast growth factor (bFGF) proteins in the conjunctiva tissue were detected by immunochemistry,and the expressions of VFGF mRNA and bFGF mRNA in the conjunctival tissue were determined by reverse transcription polymerase chain reaction (RT-PCR).Results The operative duration was (21.3±0.2) minutes in suture group and( 10.1 ±0.1 )minutes in the fibrin glue group with a significant difference between two groups( t =102.242,P<0.05 ).From 1 week through 4 weeks,the hyperemiain degree was obviously slight in fibrin glue group compared with suture group.Immunochemistry showed that VEGF and bFGF proteins were expressed mainly in the cytoplasm of conjunctival epithelium layer.The positive response intensity was weaker in the fibrin glue group than in suture group 1 week and 4 weeks after operation.RT-PCR revealed that the expression level of VEGF mRNA was significantly lower in fibrin glue group than in suture group,and the VEGF mRNA was gradually decreased with the time lapse ( Fgroup =174.443,P =0.000 ; Ftime =231.459,P =0.000 ).The similar outcomes were found in the expression of bFGF mRNA(Fgroup=41.727,P=0.000;Ftime=55.417,P=0.000). ConclusionsThe use of fibringluecanshortentheoperationdurationandreducepostoperationinflammatoryreaction.The downregulation of VEGF and bFGF in tissue is the possible mechanism of remitting irritation sign,which allows a reduce of the recurrence rate of pterygia.

To explore the application value of low-dose CT in lung cancer after operation in a short-term review by comparing conventional and low-dose CT. Methods:In 83 cases of lung cancer during the immediate postoperative period review, 50 cases (group A) underwent conventional CT scanning, whereas 33 cases (group B) underwent low-dose CT scanning. All CT scans were scored on the basis of image quality and clinical needs. The radiation dose indexes CTDIvol and DLP were recorded for each case. A comparison of the score and radiation dose between the two groups helped determine the existence of significant differences. Results:The average image quality scores of the two groups were 3.705±0.314 and 3.311±0.442, those for clinical demand were 2.670±0.373 and 2.561±0.410, those for CTDIvol were (19.248±1.532) mGy and (10.138±1.113) mGy, and those for DLP were (170.180±19.259) mGy*cm and (99.061±14.504) mGy*cm. The two groups exhibited significant differences in image quality, CTDIvol, and DLP but revealed no significant dissimilarity in clinical demand. Conclusion:Low-dose CT completely meets the clinical requirements for short-term follow-up after resection of lung cancer and significant reduction in radiation dose.
