BACKGROUND:The post space cleaning using ultrasonic file can improve the bonding strength of fiber postscemented with the self-adhesive resin cement, but the effect on apical sealing ability is stil unclear. OBJECTIVE:To evaluate the effect of the post space cleaning using ultrasonic file on apical microleakage fol owing treatment with two kinds of root canal sealers at two different residual lengths of root canal fil ing. METHODS:Eighty extracted human maxil ary anterior teeth with single-rooted canal were selected, and equivalently randomized into groups A and B (n=40 per group), fol owed by fil ed with Cortisomol or AH-plus, respectively. Groups A and B were randomly subdivided into four groups according to the residual length of root canal fil ing and with or without ultrasonic cleaning (n=10 per group):A1, B1 groups:residual 5 mm, no ultrasonic cleaning;A2, B2 groups:residual 5 mm, ultrasonic cleaning;A3, B3 groups:residual 3 mm, no ultrasonic cleaning;A4, B4 groups:residual 3 mm, ultrasonic cleaning. Subsequently, the apical microleakage was measured using dye method and transparent specimen technique under stereomicroscope. RESULTS AND CONCLUSION:The apical microleakage of each group was as fol ows:A1 (0.73±0.21) mm, A2 (1.37±0.55) mm, A3 (1.18±0.36) mm, A4 (2.05±0.62) mm, B1 (0.34±0.18) mm, B2 (0.47±0.14) mm, B3 (0.59±0.23) mm, B4 (1.39±0.50) mm. The three-factor analysis of variance revealed that the ultrasonic cleaning, root canal sealers and residual length of root canal fil ing al had a significant effects on the apical microleakage (P<0.05), and there were significant differences in the apical microleakage between groups A1 and A2, groups A3 and A4, groups B3 and B4, groups A2 and A4, groups B2 and B4 (P<0.05). These results indicate that the ultrasonic cleaning increases the apical microleakage fol owing the use of Cortisomol at 5 and 3 mm residual length, as wel as the use of AH-Plus at 3 mm residual length. Moreover, for the same root canal sealer, the longer residual length of root canal fil ing indicates, the less microleakage after ultrasonic cleaning.

Objective To analyze the clinical features of differentiated thyroid cancer diagnosed during pregnancy or one year after delivery.MethodsA total of 234 women with differentiated thyroid cancer were treated from January 2001 to January 2011.Cases were divided into three groups according to the time of tumor diagnosis( group 1,no pregnancy history; group 2,during pregnancy or in the first year after delivery;group 3,longer than 1 year after the delivery).ResultsThe thyroid nodule was asymptomatic and discovered on routine examination more often in group 2(78.7％ ) than other two groups (P =0.02).There were no significant difference among three groups in age,hospitalization time,operation time,operation method,tumor type,primary tumor stage and mortality. But more patients in group 2 were suffering from extrathyroid invasion ( P =0.024 ),multi-focal cancer ( P =0.023 ),larger cervical lymph node ( P =0.021 ),later regional lymph node stage (P =0.020 ) and higher local recurrence (P =0.001 ).By stepwise logistic regression analysis,pregnancy is one of the factors impacting on local recurrence rate ( P =0.045 ).ConclusionsPregnancy does not affect the mortality of the differentiated thyroid cancer,but the incidence of extrathyroid invasion,multi-focal cancer,cervical lymph node metastasis,local recurrence is higher in patients with differentiated thyroid cancer diagnosed during pregnancy.

BACKGROUND:The mechanism underlying orthodontic-induced external root resorption is not yet clear, and it differs individual y. Kidney deficiency has been proved to be related to bone diseases which mediated by different cytokines. Interleukin-17 is an important cytokine involved in external root resorption. So figuring out whether kidney deficiency and interleukin-17 are related to root resorption wil be helpful for etiological research.
OBJECTIVE:To explore the relationship between kidney deficiency physique, interleukin-17 and root resorption during orthodontic treatment in rats.
METHODS:Thirty-six Wistar rats were selected and equivalently randomized into two groups, fol owed by modeled into kidney deficiency (kidney deficiency group) or injected with normal saline (control group), respectively. Afterwards, the right maxil ary of each rat served as an orthodontic force model, and the left maxil ary as a non-orthodontic force model. Al rats were respectively sacrificed under general anesthesia at the 3, 7 and 14 days after given orthodontic force. Then, the mesial surface of the root of maxil ary first molars and the expression level of interleukin-17 were observed through hematoxylin-eosin staining and immunohistochemical method.
RESULTS AND CONCLUSION:Histological observation showed that significantly increasing root resorption in a time-dependent manner could be observed, and there were various absorbed lacunae of osteoclasts on the enamel in the kidney deficiency orthodontic force group. The alveolar bone resorption and widened periodontal membrane appeared in the control orthodontic force group. While no remarkable root and alveolar bone resorptions were found in the other two non-orthodontic force groups. The expression level of interleukin-17 in the kidney deficiency orthodontic force group was higher than that in the control orthodontic force group;the expression level of interleukin-17 in the kidney deficiency non-orthodontic force group was higher than that in the control non-orthodontic force group. In conclusion, kidney deficiency patients are easy to develop root resorption, the mechanism of which is maybe relevant to the upregulation of interleukin-17.

Aim To investigate the mechanism of the melanoma B16 F10 cells proliferation induced by Lico-chalcone A in vitro. Methods The proliferation of B16 F10 cells induced by Licochalcone A was deter-mined by SRB method. The morphological changes were observed using Giemsa staining under the phase contrast microscope equipped with a digital camera. The melanin level was assessed by colorimetric meth-od. The apoptotic rate was determined by Annexin V-FITC/PI assay. Cell cycle distribution was determined by flow cytometry. The mRNA expression levels of B cell lymphoma/lewkmia-2 ( Bcl-2 ) , Bcl-2 associated X protein ( Bax) , the cell cycle protein CyclinE2 and cyclin-dependent kinase-2 ( CDK2 ) CDK2 were detec-ted using Q-PCR analysis. Results The proliferation of B16 F10 cells treated with Licochalcone A was effec-tively inhibited in a concentration and time-dependent manner. A clear morphological change was observed with the increasing concentration of Licochalcone A in B16F10 cells, the dendrite-like projections changed to the narrowing ball shape, which was associated with the increasing melanin level. The low concentration of Licochalcone A could induce B16F10 differentiation, and the high concentration of Licochalcone A could in-duce B16F10 apoptosis, which was accompanied with the increasing G1 phase in cell cycle. The mRNA ex-pression levels of Bcl-2 /Bax, CyclinE2 and CDK2 were markedly reduced. Conclusion Licochalcone A can effectively inhibit the proliferation of B16 F10 cells, induced cell cycle arrest at G1 phase, and fur-ther induced differentiation and apoptosis.

Aim To evaluate the mechanism of apopto-sis induced by the isoliquiritigenin in A375 human ma-lignant melanoma cells. Methods Sulforhodamine B ( SRB) method was used to determine the A375 cell viability;acridine orange/ethidium bromide ( AO/EB) and Hoechst 33258 staining were used to observe the morphological changes of apoptotic cells; flow cytome-try was used to detect A375 cell apoptotic rate;DCFH-DA was applied to determine the changes of total intra-cellular ROS in A375 cells;JC-1 method was used to measure the changes of mitochondrial membrane poten-tial;the kits methods were used to determine the con-tent of ATP, lactic acid and glucose in A375 cell which was treated with different concentrations of isoliquiritigenin. Results Isoliquiritigenin could in-hibit A375 cell proliferation in a concentration-depend-ent manner; A375 cells showed obvious apoptosis charateristics after treatment by isoliquiritigenin, and the apoptosis rate increased with increasing concentra-tion of isoliquiritigenin. The level of total intracellular ROS in A375 cells increased obviously after dealing with different concentrations of isoliquiritigenin;in ad-dition, the mitochondrial membrane potential, the lev-els of intracellular ATP,lactic acid and the level of glu-cose uptake all declined. Conclusions These find-ings demonstrate that isoliquiritigenin can induce apop-tosis of A375 cells. The mechanism may be related to elevation of ROS level and reduction of aerobic glycoly-sis level.
