Background Refractive surgery has propelled itself forward to become widely performed surgical procedure nowadays.After the surgery,corneal biomechanics decreases lead to keratoconus and corneal ectasia.Doctors pay more attention to biomechanics changes after refractive surgeries.Objective This clinical study was to investigate the influence of different laser refractive surgeries on corneal biomechanics.Methods A prospective nonrandomized and controlled clinical study was designed.One hundred and sixty-four eyes of 82 patients with moderate myopia were enrolled.The patients were divided into sub-Bowman keratomileusis (SBK) group (60 eyes of 30 patients),laser in situ keratomileusis (LASIK) group (54 eyes of 27 patients) and laser subepithelial keratomileusis (LASEK) group (50 eyes of 25 patients),with the matched demography among the three groups.Corneal hysteresis (CH) and corneal resistance factor (CRF) were detected by ocular response analyzer (ORA) before and 1 week,5 months after refractive surgery.The correlations between stromal ablation depth and postoperative changing values of CH or CRF were analyzed.Results Significant differences were found in CH and CRF at different time points in the three groups (Ftime =41.90,P =0.00;Ftime =49.65,P =0.00),and the CH and CRF values were significantly lower 1 week and 5 months after surgery than those before surgery (all at P =0.00).However,no significant difference of CH or CRF was seen at all time points among the three groups (Fgroup =2.17,P =0.08;Fsroup =2.67,P =0.07).No correlation was found between corneal ablation depth and CH in 1 week and 5 months after surgery (both at R2 =0.000),however,weaker correlations were seen between corneal ablation depth and CRF 1 week and5 months after surgery (Y=3.253+ 0.010X,R2=0.007;Y=1.073+0.021 X,R2=0.004).Conclusions SBK,LASIK and LASEK lead to the change of corneal biomechanics by altering CH and CRF,they play the same influence on cornea.CRF appears to be an useful indicator in evaluating corneal biomechanical changes after laser refractive surgery.

Objective To examine the prevalence of plasmid mediated quinolone resistance (PMQR) genes and their correlation with the genes encoding β-lactamases in E.coli isolates.Methods A total of 200 levofloxacin-and/or ciprofloxacin-resistant E.coli isolates were collected from Fujian Medical University Union Hospital during the period from July to December 2013.PCR method was used to screen these E.coli isolates for the presence of qnrA,qnrB,qnrC,qnrD,qnrS,aac(6')-Ib-cr,qepA,oqxAB genes,and the blaTEM,blasnv and blacTx-M genes in the PMQR positive strains.Agar dilution method was utilized to measure the antimicrobial susceptibility of PMQR-positive strains.Phylogenetic analysis was conducted by triplex PCR.Enterobacterial repetitive intergenic consensus-polymerase chain reaction (ERIC-PCR) was used to evaluate the genetic similarity between the PMQR-positive isolates.Results Of the 200 clinical isolates of E.coli,58 (29.0％)were PMQR-positive.And qnr,aac(6')-Ib-cr,oqxAB,and qepA genes were positive in 11 (5.5％),41 (20.5％),16 (8.0％),1 (0.5％) strains,respectively.The genes encoding CTX-M-1,CTX-M-9 and TEM type enzymes was positive in 32 (55.2％),17 (29.3％),and 1 (1.7％) of the PMQR-positive strains,respectively.The blasHv gene was not identified in any isolate.PMQR-positive strains were multi-drug resistant.Phylogenetic analysis indicated that 21 (36.2％),17 (29.3％),11 (19.0％),and 9 (15.5％) of the PMQR-positive strains belonged to group A,group D,group B2 and group B 1,respectively.ERIC-PCR suggested the PMQR-positive isolates belonged to 50 different types.Only one strain was non-typeable.Conclusions Most of the PMQR-related genes in E.coli are aac(6')-Ib-cr,qnr,and oqxAB in our hospital,which are highly relevant to β-1actamase genes.PMQR-positive strains may spread by way of non-clonal dissemination in our hospital.

Objective: To investigate the effects of traditional Chinese medicine Xuebijing injection (血必净注射液) on tissue tumor necrosis factor-?(TNF-?) expression and blood coagulation parameters in septic rats.Methods: Wistar rats were subjected to sepsis induced by cecal ligation and puncture(CLP).Ninety-six healthy rats were randomly divided into four groups: normal group,sham operation group,CLP model group,and Xuebijing-treated group.The two latter groups were given respectively intravenous injection of normal saline or Xuebijing injection with the dose of 4 ml/kg at 0.5,12,24,36,48 and 60 hours after the establishment of CLP model.Eight rats were sacrificed at 2,8,24,48 and 72 hours postCLP in the two latter groups.Prothrombin time(PT),activated partial thromboplastin time (APTT),and fibrinogen(Fbg) levels were determined.Tissue TNF-? protein levels in liver and lung tissues were also measured at various intervals.Results: TNF-? protein levels in liver and lung tissues were significantly increased at 2 hours after establishment of CLP model compared with those of the normal group(both P

Objective Single voxel proton spectroscopy technique (1H-MRS)was performed in the healthy newborn brain tissue to investigate the metabolic ratio in the right basal ganglia and the right frontal lobe changes with gestational age, and to improve the understanding of the neonatal brain development. Methods In this study, 69 newborns were selected, including twenty-five premature and forty-four term neonates. By using the Gesell developmental scale to evaluate brain development , they all had normal neurologic outcomes at 12-months corrected age. A point-resolved spectroscopy sequence was used to study the metabolic data obtained from each region of interest. Results N-acetylaspartate: creatine and N-acetylaspartate:choline were positively correlated with gestational age (the right basal ganglia r = 0.27, 0.63, the right frontal lobe r = 0.44, 0.64 respectively, P < 0.05) and choline:creatine was negative (the right basal ganglia r = -0.51,the right frontal lobe r = -0.41, P < 0.05), with a linear regression relationship among variables. In the same gestational age group , the N-acetylaspartate: choline of the right basal ganglia was higher than that of the right frontal lobe , and the metabolic ratios among the anatomic locations were significantly different (P < 0.05). Conclusion Neonatal brain metabolite levels are associated with gestational age , and MRS can monitor newborn brain maturation quantitatively.

Objective To investigate the expression and clinical significance of neutrophil S100A8/A9 in induced sputum in children with bronchial asthma. Methods A total of 108 cases of bronchial asthma patients in the FourthAffiliated Hospital of Nanchang University were involved in the study form October 2014 to October 2015. According to the severity of the disease, the patients were divided into mild group (n=40), moderate group (n=36) and severe group (n=32). Twenty health children were taken as control group at the same period. All the patients were treated with budesonide aerosol for three months, and the control group was received aerosol inhalation for normal saline (NS). The ratio of forced expiratory volume in one second and forced vital capacity (FEV1/FVC, FEV1%) were used to evaluate the pulmonary function in two groups. The asthma control questionnaire (AcQ-5) score was used to estimate the asthma control effects. The expression level of neutrophil S100A8/A9 mRNA in induced sputum was detected by real-time PCR. The correlation of S100A8/A9 mRNA, AcQ-5 score and FEV1%was analyzed. Results Before the treatment, the FEV1%decreased, while the AcQ-5 score and express level of S100A8/A9 mRNA significantly increased with the severity of disease (all P<0.01). Three months after treatment, asthma was completely controlled in 60 patients, partial controlled in 31 cases and uncontrolled in 17 cases. With the improvement of the therapeutic efficacy, the FEV1%significantly decreased, while the express level of S100A8/A9 mRNA significantly increased (all P < 0.01). The express level of S100A8/A9 mRNA in induced sputum neutrophils was negatively correlated with FEV1%(r=-0.327 and-0.406 respectively, P<0.05), which was positively correlated with ACQ-5 score (r=0.704 and 0.817, P<0.05). Conclusion The level of S100A8/A9 expression in induced sputum neutrophil is positively correlated with the severity of asthma, which can be used as clinical indicators of the severity and the efficacy of asthma.
