Cornea is the major refractive components of the eye. As a viscoelastic tissue, cornea exhibits complicated biomechanical properties: non - linear elasticity, anisotropy and viscoelasticity. The biomechanical properties play an important role in keeping the normal structureand function. Changes in biomechanical properties are always earlier than the clinical symptoms. So quantitative measurement of the biomechanical properties benefits the early diagnosis and treatment of diseases. Different methods to measure the biomechanical properties of cornea were reviewed in detail, including classic ex vivo destructive tests, commercially available in vivo measuring methods and other emerging methods with the potential for clinical application but not validated for in vivo measurement. The operating principles, advantages as well as limitations of these methods were also described.

Objective To investigate the effects of sevoflurane preconditioning on renal ischemia-reperfusion(I/R)injury in rats.Methods Twenty-four adult male SD rats weighing 250-300 g were randomly divided into 3 groups(n=8 each):sham operation group (group S);I/R group; sevoflurane preconditioning group (group SP). After the rats underwent right nephrectomy, renal I/R was produced by occlusion of left renal artery for 45 min followed by reperfusion in I/R and SP groups.In group SP, the rats inhaled 2.2% sevoflurane for 1 h, then the inhalation was stopped and renal ischemia was performed 10 min later. Venous blood samples were collected at 2 h of reperfusion to determine the concentrations of serum creatinine(Cr), urea nitrogen (BUN), cystatin C (Cys C) . The renal tissues were obtained for microscopic examination, and Paller's score was recorded. Results Compared with group S, there was no significant difference in the serum Cr and BUN concentrations (P>0.05), while the serum Cys C concentration and Paller's score for acute renal tubular injury were significantly increased in group I/R(P<0.05). The serum Cys C concentration and Paller's score were significantly lower in group SP than in group I/R(P<0.05).I/R-induced renal injury was significantly reduced in group SP compared with group I/R. Conclusion Preconditioning with sevoflurane can provide significant protection against renal I/R injury.

Lipase from Burkholderia cepacia complex is one of the most versatile biocatalyst and is used widely in many biotechnological application fields including detergent additives, the resolution of racemic compounds, etc. Based on the known whole genomic information of B. cepacia, both ampicillin and kanamycin were added to the TB-T media, the traditional selective media, to screen B. cepacia complex strains from rhizosphere soil samples. The single colonies on the plates with the modified TB-T media were then qualitatively determined the ability to produced the extracellular lipase in the rhodamine B-olive oil agar plates. Thirty-five strains of lipolytic pseudo-B. cepacia complex were isolated and the positive rate of lipolytic bacteria was 65%. Among them, 15 pseudo-B. cepacia complex strains with the tolerance to benzene, n-hexane and n-heptane at the concentration of 10% (V/V) were selected and identified by the recA gene sequence. All of the 15 lipolytic bacteria belonged to the B. cepacia complex.
