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.

They were divided into 2 groups by random digits table method with 62 cases each. The observation group was given modern medical position pad nursing after operation, and the control group was given routine postoperative nursing. Postoperative 2 hours, 4 hours after operation, postoperative 1 day, 2 days, 3 days and before discharge pressure situation, children crushed area skin comfort, families of children with pain on pressure parts skin care satisfaction and turn the situation were analyzed and compared. Results The observation group postoperative 2 hours did not appear the skin red and bruised, there was no crushed in 4 hours, only 4 cases of skin red, no 1 case skin crushed before leaving hospital. Twelve cases of the control group in postoperative 2 hours appeared red skin pressure, 4 hour after crush skin in 4 cases, 6 cases of skin crushed before leaving hospital. The comfortable children for 56 cases, mild discomfort for 6 cases in the observation group,and 31, 23 cases in the control group. The satisfaction was 100.0%(62/62) in the observation group, and 93.5%(58/62) in the control group. The degree of turn the situation pain in the observation group was lower than that in the control group. Conclusions New medical position mat can effectively extend the pediatric orthopaedic congenital dislocation of the hip, pelvis fracture and femoral fracture with roll over time, reduce the stimulation of the skin, sweat for pressure parts effectively prevent the occurrence of pressure sores, improve the crushed area comfort children and families of children with satisfaction, greatly reduce the postoperative pain when rolled over, worth clinical promotion.

Objective To explore the practical new type of patient information sign on the application effect of pediatric surgical ward. Methods Divided 200 cases of patients in our department into the control group and the observation group according to random number table, there were 100 cases in each group. The control group and the observation group in A and B ward respectively, A ward (control group) used the traditional end of the bed, B ward (observation group) used the new information sign. The incidence rate of adverse events, patients′ families health mission efficiently, satisfaction of patients or medical staff were compared between the groups. Results The incidence rate of adverse events in the observation group was significantly lower than that of in the control group [1%(1/100) vs 8%(8/100),χ2=5.701, P < 0.05]. The effectiveness of health education, satisfaction of patients or medical staff and patients′families to health mission satisfaction in the observation group were significantly higher than that of in the control group [91% (91/100) vs 79% (79/100), 97% (97/100)vs 84% (84/100), 98% (98/100)vs 86% (86/100),the value of χ2 was 5.647,9.828 and 9.783 respectively, P < 0.05)].

Objective To evaluate the efficacy of long-term lamivudine therapy in patients with decompensated cirrhosis after HBV infection. Methods The clinical courses and outcomes of lamivudine therapy in 60 patients with decompensated cirrhosis were observed and the results were compared with those in historical control group who did not receive lamivudine therapy. Kaplan-Meier method was used to measure the survival rates of two groups. Results There was significant improvement of Child scores in the treatment group, which were 9.4±2.4 at the baseline and 8.3±1.8, 6.5±2.2, 6.3±0.7 at 12 months,24 months and 36 months of the therapy (P<0.01), respectively. Significant clinical improvements were observed in 20 patients in the treatment group, but no improvement was observed in the controls. The rates of serum HBV DNA clearance was 84.7% (50/59), 89.2% (50/56), 76.8% (40/52) and 72%(36/50) at 6 months, 12 months, 24 months and 36 months of the therapy. And the rates of YMDD mutant were 0, 7% (4/56), 17.3% (9/52) and 26% (13/50) at these time points. The survival rates for the treatment group were 77.7%, 50% and 46. 5% at 1 year, 2 year and 3 year, while those in the control group were 71.28%, 45% and 43.5%, the difference was of no statistical significance (P=0.12).Conclusion Lamivudine therapy can significantly improve the liver function in patients with decompensated cirrhosis, but it may not improve the survival of patients.
