Objective :
To observe the clearance of smear layer on the root canal wall in different action time by scanning electron microscope (SEM), and to determine the optimal amount of time using sonically activated irrigation to wash root canal in clinic.
Methods:
Fifty-six ex vivo human anterior teeth with single straight root canal were selected. After routine mechanical preparation, they were divided into two experimental groups according to different irrigating agents: saline group and EDTA group. Each group was assisted by VDW sonic activation EDDY. The saline group was divided into three subgroups according to the irrigating time: 5 s, 30 s and 50 s; EDTA group was divided into six subgroups according to the irrigating time: 5 s, 10 s, 20 s, 30 s, 40 s and 50 s. The control group did not undergo root canal irrigation. After irrigation, the root was cut longitudinally. The smear layer of crown, middle and apical of root canal wall was observed by SEM.
Results:
After irrigating for 30 seconds, there was a significant difference between the normal saline group and the control group and the 5 second group (P<0.05), and there was no difference in the middle and apical part (P>0.05). After 50 seconds, there was a significant difference in the score of the smear layer between the apical area and the other groups (P<0.05). After irrigating for 5 seconds or 10 seconds in EDTA group, there was a significant difference between the scores of the crown and middle area of the root canal and the control group (P<0.05), and there was no significant difference in the apical area (P>0.05). There was a significant difference between the 20-40 second group and the first two groups (P<0.05). There was a significant difference between the 50 second group and the other groups (P<0.05). Comparing the cleaning effect on the smear layer after 50 seconds of irrigating between the two experimental groups, the whole root canal showed significant statistical difference (P<0.05).
Conclusion
The EDTA-assisted sonic activated device used for 50 seconds has the best cleaning effect.

OBJECTIVETo detect expression of p-glycoprotein (P-gp), multidrug resistance-associated protein (MRP), and glutathione S-transferase (GST-pi), and to evaluate its clinical significance in neuroblastoma (NB).
METHODSSP immunohistochemical technique was used to investigate expression of P-gp, MRP, and GST-pi in 70 cases of NB.
RESULTSThe frequency of expression of P-gp, MRP, and GST-pi was 61.4%, 38.6%, and 51.4%, respectively. The coexpression rate of P-gp and MRP, P-gp and GST-pi, MRP and GST-pi, P-gp, MRP and GST-pi was 32.9%, 35.7%, 27.1%, and 24.3%, respectively. Significant positive correlation was observed between P-gp and MRP expression (P = 0.001), and between MRP and GST-pi expression (P = 0.012), but no correlation was found between P-gp and GST-pi expression. The expression of P-gp and MRP was higher in tumors from patients over 1 year old compared with those less than 1 year old at diagnosis (P = 0.01, 0.018, respectively). MRP expression was higher in tumors from the metastatic than the non metastatic groups (P = 0.015). All tested proteins showed significant relationship to the differentiation of the tumor (P = 0.006, 0.000, 0.019, respectively), but no correlation was found to the stage of NB or sex of the patients. MRP expression was significantly related to the reduction of both median survival time and the two-year cumulative survival (P = 0.02). In contrast, P-gp and GST-pi expression had no correlation with survival.
CONCLUSIONSThe intrinsic multidrug resistance of NB involves the combined effects of P-gp, MRP, and GST-pi. MRP expression may be an important parameter in predicting the prognosis of patients with NB.

Objective: To investigate the ethical decision-making process of breaking confidentiality when counselors dealing with self-inflicted injury and suicide issues in college situation. Methods: A semi-structural interview was addressed to 10 counselors from 7 college counseling centers in Beijing, among whom with (10 ± 8) years of experience on average in this field. Content analysis method was used to transcription of the interviewing data. Results: Totally 8 counselors had received ethical training more or less, and attached great importance to ethical codes. There were still some conflicts between school regulations and confidentiality rules in 7 university counseling centers. Different counselors varied greatly in decision-making on breaking confidentiality when facing college students' self-inflicted injury and suicide. Faced with conflicts between college demands and confidentiality principles, counselors could take the professional standpoint and consider more of the interests of students. Conclusion: The decision-making process on self-inflicted injury and suicide confidentiality breakthrough needs to be standardized. College's attention and support to the counseling work should be strengthen and enhance ethical awareness.
