Results indicated that expression of serum sFas, TNF - a and IL - 2 before treatment was significantly higher than those of the control group (P0. 05), and the IL-2 level still was higher than the normal (P

Objective To evaluate the alteration of labial bone mass one year after immediate implant or delayed implant placement in esthetic zone.Methods From June 2009 to June 2012,22 patients with 11 immediate implant and 11 delayed implant in the maxillary anterior region were followed up.CBCT images were obtained immediately after surgery and one year after implant placement,the horizontal and vertical alterations of the labial bone were evaluated by image analysis software.Results The 1-year vertical reduction of labial bone after immediate implant placement was statistically significant (P＜0.05),and no significant difference in delayed implant (P＞0.05).The 1-year horizontal reduction of labial bone was statistically significant at coronal and middle of implant,without significant difference at apical of implant.Conclusions Immediate implant can not stop the physical absorption of labial alveolar ridge,and the study can provide reference to achieve esthetics in the anterior region.

Objective To investigate the status of research and research utilization in practice among nurses of hospital of Traditional Chinese Medicine.Methods Two hundred and sixty nurses of hospital of Traditional Chinese Medicine were selected to fill out the questionnaire.Results The rates of involvement of research activities and research utilization among nurses of hospital of Traditional Chinese Medicine were low.The score of every factor ranged from the higher to the lower were communication,organization,research and nurse.Conclusions Involvements of research activities and research utilization among nurses of hospital of Traditional Chinese Medicine are insufficient.Most factors associated with nurses' low extent of research utilization are objective factors.It is pivotal for nursing managers to construct supportive professional environment,improve nurses' research and information skills and the capacity of the research utilization.

BACKGROUND:As the rapid development of oral implantation and restoration techniques, as wel as the increasing enlargement of indications, angulated abutments have been widely used. Posterior teeth region, as the weight-loading region of occlusion, can bear great force from the implants, the assessment of angulated abutments in posterior teeth region has clinical value.
OBJECTIVE:To evaluate the short-term clinical efficacy of angulated abutments on the implant denture in posterior teeth region.
METHODS:From January 2008 to January 2013, 114 patients with 175 ITI implants in the posterior teeth region were included in this study and they al underwent single-crown restoration. The involved patients were divided into angulated abutment group and straight abutment group. Periodontal probing depth, modified plaque index, modified sulcus bleeding index and peri-implant crestal bone loss in two groups were recorded at 6 months and 2 years after restoration. Cumulative survival rate of the implant denture was calculated by life-table analysis.
RESULTS AND CONCLUSION:There was no significant difference in periodontal probing depth, modified plaque index, and modified sulcus bleeding index between two groups (P>0.05). The annual crestal bone loss showed no significant difference between two groups (P>0.05). Moreover, the 5-year cumulative survival rate with 15° and 20° abutments was 95.6%, and that with straight abutment was 96.4%. The angle of abutments has no correlation with peri-implant soft tissue and peri-implant crestal bone loss, implant restorations with 15° and 20° angulated abutments may be successful y used in the posterior region, whereas the long-term effects need further research.

Objective To examine the expression of CD8+CD28- T cells in the peripheral blood and explore their roles in the pathogenesis of AS. Methods The expression of CD8+CD28- T cells obtained from 50 AS patients and 21 healthy controls were assayed by flow cytometry. CRP was also measured. Results The percentage of peripheral blood CD8+CD28- T cells in patients with AS was significantly increased compared to normal individuals [(18±6)% vs (14±5)%, P=0.020], while the percentage of peripheral blood CD3+,CD8+ CD28+ T cells in patients with AS was significantly decreased[ (65±9)% vs (69±8)%, P=0.039]; [ (15±5)% vs(18±4)%, P=0.038]. No difference was found in CD8+ T cells between patients with AS and normal individuals(P＞0.05). Conclusion The percentage of peripheral blood CD8+CD28- T cells in patients with AS is significantly increased comparing to normal individuals. This suggests that CD8+CD28- T cells may play an important role in the pathogenesis of AS.

Objective To explore the possible correlation between periodontal disease and carotid arteries atherosclerosis in old people,and to study the diagnostic value for periodontal disease using three-dimensional (3D) reconstruction technique of multi-slice spiral CT (MSCT).Methods Patients underwent multi-detector row CT angiography with carotid arteries atherosclerosis (control group) and without carotid arteries atherosclerosis (case group) were evaluated with the stereoscopic configuration of teeth,and the number of decayed teeth and lost teeth were recorded.Results Bythe 3D reconstruction technique,the number of decayed teeth and lost teeth between two groups were significantly different (P＜0.05).The number of dental integrity patients was higher in control group (19 cases) than in case group(7 cases).The mean of dental caries was higher in control group(7.3±3.0) than in case group(6.0±2.1).The mean of hypodontia was higher in control group(45 cases) than in case group(39 cases) (P＜0.05).Conclusions The 3D reconstruction technique of MSCT is a new method to display the stereoscopic configuration of teeth.The periodontal disease is significantly related with carotid arteries atherosclerosis in old people.
