·AIM: To investigate the effect of vitamin A on the conjunctival goblet cells of rat after corneal transplantation.·METHODS: Rat graft rejection models of corneal transplantation were established. SD rats were receptor and Wistar rats were donors. After corneal allografts were performed, 48 SD rats were randomly divided into three groups, 16 rats in each group. Group A was blank control group; group B was treated by oculotect gel (containing vitamin A); group C was treated by 1g/L dexamethasone eyedrops. Besides, group D was normal unoperated eyes.Slit-lamp microscope was employed to record and compare rejection index (RI) of corneal transplantation. Through HE,PAS staining of conjunctival histological sections and image analysis system, the number and morphology of conjunctival goblet cells were observed and analyzed between operation group and normal group.·RESULTS: The HE, PAS staining detection showed that the number of conjunctival goblet cells in oculotect gel group,1g/L dexamethasone eyedrops group and control group is lower than that in normal group after surgery (P＜0.01). The number of conjunctival goblet cells in oculotect gel group and 1g/L dexamethasone eyedrops group is higher than that in control group (P＜0.05). The number of conjunctival goblet cells in 1g/L dexamethasone eyedrops group is higher than that in oculotect gel group (P＜0.05).·CONCLUSION: The results indicate that vitamin A may inhibit the decrease of conjunctival goblet cells after corneal allograft rejection in rats.

Objective To study the rehabilitation effects of the cochlear implants on prelingually deaf children with alba abnormality.Methods A retrospective analysis of the effects of CIs was conducted in the prelingually deaf children of 11 cases of the children with abnormal alba(the research group) and 18 cases of the children who had normal alba(the control group) at the First Affiliated Hospital of Fujian medical university.All the operations were completed by the same doctor.There were no obvious complications during and after the operation.The cochlear implants were turned on after one month and the prelingually deaf children with extremely severe bilateral sensorineural deafness were trained for speech at the rehabilitation centre.The assessment criteria of the categories of auditory performance(CAP) and speech intelligibility rate(SIR) were used.After six months and twelve months of the operation, the family members were followed who have direct contacts with the children.The evaluation of data between the research and the control groups was administered.Results In the research group, the average level of CAP after six months'' post-operation was 2.41±0.47.But in the control group, the average level was 3.28±0.45.In the research group, the average level of SIR after six months'' post-operation was 1.27±0.44.There were 3 children in the research group at level 2, but in the control group, the average level was 1.89±0.31.Two children in the control group were level 1 while the others were level 2.In the research group, the average level of CAP after twelve months'' post-operation was 4.00±0.43 while only one child at level 3.There was one child at level 5 in the research group, the rest were level 4.There was a statistically significant difference in the average level of the CAP after six months'' post-operation(t=4.983, P<0.05) and in the average level of the SIR after six months'' post-operation(t=4.371, P<0.05).There was no statistical difference in the average level of the CAP after twelve months'' post-operation(t=1.033, P>0.05) and in the average level of the SIR after twelve months'' post-operation(t=0.434, P>0.05).Conclusion There is no significant difference of the rehabilitation effects of post-operation between the prelingually deaf children with alba abnormality and those with normal alba.

Objective To investigate the antimicrobial activity of fosfomycin combined with other antibiotics against carbapenem-resistant enterobacteriaceae(CRE).Methods A total of 233 non-repititive CRE isolates were collected from January 2010 to December 2014 from 4 hospitals, including Second Affiliated Hospital of Zhejiang University School of Medicine, Hangzhou Traditional Chinese Medicine Hospital, Zhejiang Provincial People's Hospital and Second Hospital of Jiaxing.Antimicrobial susceptibility of fosfomycin, imipenem, meropenem, cefepime, ceftazidime, ceftriaxone, cefperazone-sulbactam, piperacillin-tazobactam, ciprofloxacin, amikacin, tobramycin, polymyxin B and tigecycline were determined by agar dilution method.Synergistic effect between fosfomycin and other antibiotics, including meropenem, cefepime, ceftazidime, cefperazone-sulbactam, ciprofloxacin, amikacin, tobramycin and tigecycline against 30 CRE isolates was determined by chequerboard assay.Chi-Square test was used for statistical analysis, and the difference was statistical significant when P<0.05.Results An overall 45.1%(105/233) of 233 CRE isolates were resistant to fosfomycin.Among which, Klebsiella spp.possessed the highest resistance rate (61.9%,73/118), followed by Enterobacter spp.(50%,15/30), Serratia marcescens (25%,7/28), and Escherichia coli (8.2%,4/49).Fosfomycin in combination with tigecyclin showed best activity against CRE isolates with a synergy rate of 76.7%(23/30).Fosfomycin and aminoglycosides also presented good activity against CRE isolates with synergy rate of 53.3%(16/30) to 70.0%(21/30).Synergism was observed only in 30%(9/30) of CRE isolates for the combination of fosfomycin and ciprofloxacin.As for the combination of fosfomycin and β-lactam antibiotics, even less synergism was observed ( 0%-3.3%) ( 1/30 ).No antagonism was demonstrates among all of the combinations.Conclusions Fosfomycin demonstrates certain in vitro activity against CRE isolates.A combination of fosfomycin and tigecyclin or aminoglycosides shows good activity, which suggests a new strategy in the campaign against serious infections caused by CRE.

Objective To identify the expression pattern of IGF-1 and IGF-1R in NK/T-cell lymphoma (NK/TCL) cell lines and to investigate the role of IGF-1/IGF-1R signaling in regulation of cell migration and invasion.Methods RT-PCR and immunofluorescence were performed to detect the expression of IGF-1 and IGF-1R.Transwell assay was applied to observe the effects of IGF-1/IGF-1R signaling and downstream kinases activities on cell migration and invasion.Concentrations of MMP-2 and MMP-9 were quantified by ELISA.Results Co-expression of IGF-1 and its receptor IGF-1R were identified in two NK/TCL cell lines,SNK-1 and SNK-6,while normal NK cells lack the IGF-1R expression.IGF-1R inhibitors significantly reduced SNK-1 and SNK-6 cells migration and invasion rates.Exogenous IGF-1 promoted both cell lines migration and invasion,but these effects were both blocked by IGF-1R inhibitors.Inhibition of AKT,p38 and JNK,the possible IGF-1R downstream kinases,reduced cell migration rates.Further more,exogenous IGF-1 significantly increased MMP-2 and MMP-9 secretion,while decreased secretion of MMP-2 and MMP-9 were observed when IGF-1R inhibitors were applied.Conclusion An autocrine IGF-1/IGF-1R signaling loop is aberrantly expressed on NK/TCL cells and the autocrine loop significantly promotes cell migration and invasion through activation of p38,PI3K and JNK signaling and enhances secretion of MMP-2 and MMP-9.
