Objective To explore the effects of proteasome inhibitor bortezomib alone and in combination with chemotherapeutic agents in acute leukemia cell line HEL. Methods Tumor cell growth inhibition and apoptosis was measured by MTT assay and FACS analysis, respectively. Apoptosis- and cell cycle-associatd protein expression levels were measured by Western blotting assay. Results Bortezomib induced the suppression of tumor cell growth and apoptosis in a dose-dependent manner with an inhibitor concentration IC50 values 7.15 nmol/L in acute leukemia cell line HEL. Further combination treatment with doxorubicin or cytarabine increased tumor cell growth suppression in acute leukemia cell line, as compared to single drug treatment alone. Bortezomib caused an increase in G2/M in a time-dependent manner. Bortezomib alone and in combination with chemotherapeutic agents treatment increased the bax and p27 expression and decreased the bcl-2 expression even without influencing p53 expression levels. Conclusion Bortezomib may be an effective therapeutic drug for patients with acute leukemia. Combining bortezomib with doxorubicin might be more effective for displaying tumor cell growth inhibitor effects in acute leukemia cells through regulation of bcl-2, bax and p27 proteins and independent of p53 status.

Objective To study the influence of different kinds of disinfection methods on antibacterial activity of TiO2 nanotubes. Methods TiO2 nanotubes were fabricated with 0.5%wt HF on pure titanium to acid-etching combined with an? odization as experimental group. The pure Ti was control group. They were disinfected by three kinds of disinfection meth?ods, which were alcohol immersion, autoclaving and UV irradiation. The bacterial adhesion ability was evaluated by observ?ing the morphology of samples, measuring the roughness and contracting angle. The film contact method was used to evaluate the antibacterial activity of samples with Staphylococcus aureus (Sa) after different infection treatment. The bacterial morphol?ogy was observed by field emission scanning electron microscope (FE-SEM). Results The treatment group has higher sur?face roughness. The bacterial adhesion ability of experimental group was stronger compared with that of control group. The contracting angle of samples exposed to UV irradiation was smaller than that of alcohol immersion and autoclaving treatment group. The viable count and FE-SEM showed that there were more bacteria and more complete morphology on the sample surface after alcohol immersion. The viable count was less and bacterial morphology suffered some damage on the sample sur?face after high pressure steam sterilization. The least viable count and the most complete destruction of bacterial morphology were found after ultraviolet (UV) germicidal irradiation. Conclusion UV irradiation shows the best antibacterial activity, the second is autoclaving and the worst is alcohol immersion.

BACKGROUND: Root canal files fracture is a kind of common oral clinical complications. Therefore, it is of clinical importance to study the cyclic fatigue of different types of stainless steel root canal files.OBJECTIVE: To explore the effect of the bending angle and cross-sectional area of root canal instruments on cyclic fatigue of stainless steel files.METHODS: Thirty 25# stainless steel K files (25 mm in length) were selected, the same to 30# and 35#. And these three kinds of files were respectively randomized into three groups (n=10 per subgroup). In the nine subgroups, the files were placed into self-made root canals at the bending angle of 45°, 60°, 90°, and driven by a 16:1 reducer (350 r/min).Fracture time in each subgroup was recorded and converted into the number of rotations. The microstructure of the fracture end of the files was observed under scanning electron microscope. Fractured files were collected and the crack tip length was measured by an electronic caliper.RESULTS AND CONCLUSION: At the same bending angle, the number of rotations resulting in file fracture was significantly reduced with the increasing of the cross-sectional area of the files (P < 0.05). When the type and cross-sectional area were same, the number of rotations resulting in file fracture was significantly reduced with the increasing of the bending angle of the root canals (P < 0.05), indicating a reduction in the cyclic fatigue performance of the files. Toughness fracture occurred in all the files, and circular or oval roughness nests with different sizes and microcavities formed on the fracture surface. In addition, brittle surfaces could be detective between the roughness nests. The diameter of roughness nests was gradually increased with the increasing of the bending angle of the root canals. For 30# and 35# files, the number of brittle surfaces was gradually increased with the increasing of the bending angle of the root canals. For 25# files, the crack tip length was gradually decreased with the increasing of the bending angle of the root canals, but there was no significant difference (P > 0.05). For 30# and 35# files, the crack tip length was significantly shortened with the increasing of the bending angle of the root canals (P < 0.05). But there were no significant changes in the 35#-60° and 35#-90° groups (P=0.095). At the same bending angle, there were no regular changes in the crack tip length in the different types of files. In conclusion, with the increasing of the cross-sectional area, the cyclic fatigue performance of the files with the same length and taper is reduced and the files become easy to be fractured; with the increasing of the bending angle of the root canals, the files with the same types are apt to be fractured near the root tip, indicating the shorter length of the crack tip indicates the more difficulty in the removal of the broken files.
