Metformin was widely recommended as a first‐line drug for patients with type 2 diabetes mellitus(T2DM ). However ,studies have shown that patients who start metformin as monotherapy often required additional agents to maintain glycaemic control with the natural progression of T 2DM. Anti‐diabetic agents may be used in combination with metformin ,including sulfonylureas ,glinides , thiazolidinediones(TZDs) ,α‐glucosidase inhibitor (AGDI) ,dipeptidyl peptidase‐4 inhibitor (DPP‐4) and glucagon‐like peptide‐1 (GLP‐1 ) or insulin. This paper mainly reviews the recent studies about the therapeutic effect of metformin in combination with other anti‐diabetic agents.

To study the effect of hyperbaric oxygen (HBO) on the activity of superoxygen dismutase (SOD) and catalase (CAT) in spinal cord tissue, a rat spinal cord injury (SCI) model was established. The results showed that the activity of SOD and CAT in the spinal cord decreased significantly after injury, bat recovered after the treatment with 0 25MPa HBO and 0 25MPa HBO+hormone. These results suggest that HBO can increase the activity of anti oxidase in spinal cord,and prevent or relieve the injury by free radicals. Thus it can recover the function of spinal cord.

To study the mechanism of hyperbaric oxygen (HBO) on spinal cord injury (SCI), we duplicated a SCI model and determined the concentrations of excitatory amino acids [EAA, including aspartic acid (Asp) and glutamic acid (Glu)] in spinal cord tissue after treated with 0 1 MPa HBO, 0 25 MPa HBO, 0 25 MPa N 2 O 2 and hormone, respectively. The results showed that the concentration of EAA (Glu) in the spinal cord significantly increased after injury, whereas after treatment it decreased in all but the N 2 O 2 group. It decreased most significantly in 0 25MPa HBO and 0 25MPa HBO+hormone groups. There were significant differences between 0 25MPa HBO group and 0 1MPa HBO group, 0 25MPa HBO+hormone group and pure hormone group ( P

Objective: To evaluate effect of the morphology of simulated S-shaped root canals with Reciproc or Mtwo instruments on root canal irrigation. Methods: A total of 40 simulated S-shaped resin blocks were randomly divided into 2 groups (n=20), which was prepared by Reciproc or Mtwo. Blue ink was injected with constant speed and volume into the canals using 30G lateral opening syringe. hTe distance from needle tip to apex and vapor lock length were measured. A type of 25# 0.04 gutta-percha point was used to stir and remove the vapor lock. hTe time for removal of the vapor lock was recorded. Another syringe was used to inject saline into the canals and to measure the length of stagnant water. Results: hTe distance from needle tip to apex in the Reciproc group was signiifcantly longer than that in the Mtwo group [(4.276 ± 0.221) mm vs (3.459 ± 0.205) mm,P<0.05]. The vapor lock length in the Reciproc group was signiifcantly longer than that in the Mtwo group [(4.472 ± 0.230) mm vs (3.668±0.217) mm,P<0.05]. hTe time to remove vapor lock was signiifcantly shorter in the Reciproc group than that in the Mtwo group [(10.13 ± 1.79) s vs (15.29 ± 2.15) s,P<0.05]. The length of stagnant water was also shorter in the Reciproc group than that in the Mtwo group[(1.351 ± 0.142) mm vs (2.245 ± 0.206) mm,P<0.05]. Conclusion: hTe morphology of S-shaped root canal affects the root canal irrigation. hTe effect of root canal irrigated by Reciproc is better than that by Mtwo.

Objective A close relationship between atherosclerosis and plasma levels of advanced oxidation protein products (AOPP) has been demonstrated in patients with chronic renal failure. The present study was performed to investigate the effect of AOPP on human endothelial cells. Methods Human umbilical vein endothelial cell line ECV304 was incubated with different concentrations of AOPP-BSA, which prepared by combining BSA with HOCl at different molar ratios. Cell viability was measured by MTT assay. Intracellular production of reactive oxygen species (ROS) was evaluated kinetically using VICTOR Wallac 1420 mutilabel counter. Results AOPP-BSA decreased endothelial cell viability, which was dependent on the molar ratio of BSA/HOCl and the concentration of AOPP-BSA. AOPP-BSA also enhanced the intracellular ROS production in ECV304. AOPP-induced ROS production was correlated with the molar ratio of BSA/HOCl and the concentration of AOPP-BSA. Pretreatment of cells with a small molecular glutathione peroxidase mimic (ebselen) reduced AOPP-induced ROS production by 53% with preservation of cell viability. Conclusion AOPP decreased endothelial cell viability via induction of oxidative stress.
