Background Blepharitis is an induce factor for multiple ocular surface diseases.Research showed that bacteria play an important role in the pathogenesis of blepharitis.To make sure the pathogenic bacteria and effective antimicrobial agents are of clinical significance for the prevention and treatment of blepharitis.Objective The purpose of this study was 1o investigate the bacterial isolates of conjunctival sac secretion and meibomian secretion in the patients with blepharitis and study their in vitro antimicrobial susceptibility.Methods Forty-five patients with anterior blepharitis and 45 cases with posterior blepharitis were included in Beijing Chaoyang Hospital from December 2006 to December 2012,and 45 patients for laser in situ keratomileusis were enrolled in the same period as control group.The secretions of the conjunctival sac and meibomian were collected with sterile cotton swab,and bacterial isolates were cultured in bouillon culture-medium.The number of eyes with different bacteria was examined and calculated.Then the bacteria were switched to blood agar plates,and antimicrobial susceptibility test to erythromycin,gentamicin,tobramycin,rifampin,levofloxacin were performed by M ueller Hinton (M-H) medium paper method.Results The total germiculture positive rates were 81.1％,76.1％ and 65.0％ in the anterior blepharitis group,posterior blepharitis group and the control group,showing a significant difference among them (x2 =12.80,P=0.00).The germiculture positive rates in meibomian secretion were 84.4％ and 78.8％ in the anterior blepharitis group and the posterior blepharitis group,which were significantly higher than 67.8％ in the control group (x2=7.30,P =0.03).There was no statistically significant difference in the germiculture positive rate of conjunctival sac section among the three groups (77.8％,73.3％ and 62.2％) (x2 =5.60,P=0.06).The main bacteria in conjunctival sac secretion and meibomian secretion were staphylococcus epidermidis,staphylococcus aureus and corynebacterium in all the subjects,but streptococcus pneumoniae and gram-negative bacillus were not detected in the control group.Staphylococcus showed the highest susceptibility to gentamicin,tobramycin and rifampicin,with the sensitive rate ＞70％.Corynebacterium was susceptible to various drugs.Streptococcus pneumoniae had susceptibility to erythromycin and tobramycin.However,Gram-negative bacillus was not susceptible to all the drugs above.Conclusions Bacteria participate in the pathogenesis of blepharitis,but the germiculture positive rate,bacterial species and drug susceptibility of bacteria are obviously different between patients with blepharitis and normal population.Reasonable application of antimicrobial agents is important to blepharitis.

Nuclear magnetic resonance (NMR) spectroscopy can be used to both identify and quantify chemicals from complex mixtures. Over the last several decades, significant technical and experimental advances have made quantitative nuclear magnetic resonance (qNMR) a valuable analytical tool for quantitative measurements of a wide variety of samples. This particular approach is now being exploited to characterize the metabolomes of many different biological samples and is called quantitative metabolomics or targeted metabolic profiling. In this review, some of the strengths, limitations of NMR-based quantitative metabolomics will be discussed as well as the practical considerations necessary for acquisition with an emphasis on their use for bioanalysis. Recent examples of the application of this particular approach to metabolomics studies will be also presented.

This study was aimed to investigate the mechanism of CO-releasing molecules (CORM-2) induced apoptosis and the intervention effect of Xingnaojing (XNJ) Injection in neuronal cells of rats. Optical microscope was applied to observe morphologic changes of neuronal cells. MTT assay was performed to assess the survival rates of CORM-2 on neuronal cells. Apoptosis was examined by flow cytometric analysis and the expression of relative proteins was measured by western blotting analysis. At the same time the morphologic changes, survival rates and expression of relative proteins of neuronal cells were also checked after XNJ treatment. The results showed that CORM-2 can influence survival rates in a time- and concentration-dependent manner. Survival rates decreased gradually after the cultures subjected to 24 h with 100 μmol·L-1, 200 μmol·L-1, 400 μmol·L-1 and 800 μmol·L-1 of CORM-2. It can induce neuronal apoptosis and activate Caspase-3, Caspase-9 and Cytochrome C in a concentration-dependent manner. The neuronal cells were treated with 200 μmol·L-1 of CORM-2 and then incubated with 10 mL·L-1 and 20 mL·L-1 XNJ injection for 20 h. It turned out early neuronal apoptosis decreased and the expression of Caspase-3, Caspase-9 and Cytochrome C also decreased. To sum up, CORM-2 may induce neuronal apoptosis through Caspase-dependent mitochondrial pathway, which can be intervened by XNJ Injection through inhibiting Caspase-dependent mitochondrial pathway.

Objective To study the relationship between uric acid and various cognitive functions in Alzheimer's disease (AD).Methods A total of 46 patients with AD and 50 people without cognitive disorder were selected.Plasma uric acid,MOCA,and ADL were measured.Results The mean level of plasma uric acid was (217.93 ± 67.91 )μmol/L in ADs,and (337.02 ± 59.70) μmol/L in controls.The mean level of uric acid was significantly lower in the blood of patients with AD than control with a statistically significant difference ( t =9.142,P ＜0.01 ).Multiple regression analysis revealed that low uric acid,age,educated years,and hypertension were related to cognitive function( P ＜0.01,P ＜0.05 ).Partial correlation analysis revealed uric acid was significantly related to memory ( r =0.457,P =0.002),and attention ( r =0.398,P =0.008).Conclusions Low levels of uric acid may have influence on the occurrence and development of cognitive function impairment in AD.Uric acid may have more influence on the memory and attention in patients with AD.
