Exploring the functional network during the interaction between emotion and cognition is an important way to reveal the underlying neural connections in the brain. Sparse Bayesian network (SBN) has been used to analyze causal characteristics of brain regions and has gradually been applied to the research of brain network. In this study, we got theta band and alpha band from emotion electroencephalogram (EEG) of 22 subjects, constructed effective networks of different arousal, and analyzed measurements of complex network including degree, average clustering coefficient and characteristic path length. We found that: (1) compared with EEG signal of low arousal, left middle temporal extensively interacted with other regions in high arousal, while right superior frontal interacted less; (2) average clustering coefficient was higher in high arousal and characteristic path length was shorter in low arousal.

BACKGROUND:The fiber-reinforced composite resin adhesion fixed bridge produced by everStick fibre reinforced composites is a kind of minimaly invasive fixed prosthesis technology in recent years, which is wel thought of patients and clinicians because of its smal tooth preparation, high success rate of bonding, good esthetic effects, strong mechanical properties and easy to intraoral repair. OBJECTIVE:To investigate the advantage of everStick fibre reinforced composites on too smal anterior edentulous space restoration. METHODS:A total of 23 patients with maxilary lateral incisor missing and with smal edentulous space were colected and renovated with everStick fibre reinforced composites produced by StickTech in Finland. RESULTS AND CONCLUSION:everStick fibre reinforced composites for repair of too smal anterior edentulous space with adhesion fixed bridge could not only avoid the overclosed occlusion on adjacent teeth like fixed denture, but also avoid the usage of clasp and uncomfortableness such as removable denture. During the folow-up of 6-30 months, 23 patients had no signs of loosening, debonding, fracture, excessive wear, secondary caries, margin dying of restoration and exhibited good margins and composite luting-cement interface, unchanged color, good esthetic effects. The patients were very satisfied with the restoration. The results indicate that everStick fibre reinforced composites for restoration of too smal anterior edentulous space can achieve good abrasion resistance and high mechanical strength, unchanged color, have little damage to abutment and have good esthetic effects.

Objective To investigate clinical value of the emergency endoscopic sclerotherapy and tissue adhesives embolization on patients with gastroesophageal varices bleeding. Methods A retrospective analysis of 52 cases of esophageal variceal bleeding in patients with clinical data was performed. Of which,22 patients were given conservative treatment alone and they were served as conservative treatment group. Another 30 patients were given the emergency endoscopic sclerotherapy and/ or tissue adhesive embolization besides the basis of conservative treatment,and they served as endoscopic treatment group. The data of hospitalization and mortality,rebleeding rates were recorded during hospitalized time and 1 year off hospitalization. Results The indices of hospitalized periods in endoscopic treatment group was( 16. 2 ± 1. 5)d,shorter than that in conservative treatment group((17. 6 ± 2. 1)d,P = 0. 53). The mortality and rebleeding rate in endoscopic treatment group in followed up periods were 3. 3% and 6. 6%,lower than those in conservative treatment group (9. 1%,13. 6%),and the comparison of relative risk RR of two groups of mortality and rebleeding rate were 2. 76 and 2. 06. Conclusion The therapy of emergency endoscopic sclerotherapy and tissue adhesives embolization of bleeding esophageal varices shows a good effect and it is worth recommending.

Objective:To observe the occlusal changes of patients with chronic periodontitis(CP)after initial periodontal therapy an-alysed by T-scan Ш occlusal analysis system.Methods:26 patients with CP were included.The patients were treated by initial perio-dontal therapy,including scaling,subgingival curettage,root planning and oral hygiene instruction.The occlusion time(OT),disoclu-sion time(DT),center of force trajectory(COFT),the percentage of bite force for maximum movie force at maximum area frame (MABF /MMF)and the bite force distribution balance between the left and right sides (BFDB)were measured by T-scan III occlusal analysis system before and six weeks after the treatment.All the data were statistically analyzed.Results:After initial periodontal treatment,the OT and DT extended for (0.20 ±0.14)s and (0.11 ±0.08)s respectively(P <0.05),the COFT increased by (0.81 ±1.19)mm(P <0.05).Moreover,the MABF /MMF and BFDB decreased by(7.20 ±4.41)% and (8.90 ±7.71)% respectively (P <0.05).Conclusion:Initial periodontal treatment may improve the occlusion of patients with chronic periodontitis.

BACKGROUND:As a kind of fiber composite resin adopt the technology of fibre reinforcement composites, the everStick high-strength fiber composite resin has been applied in the field of dentistry prosthodontic treatment restoration.
OBJECTIVE:To summarize the research condition about the material performance and clinical application of the everStick high-strength fiber composite resin
METHODS:We searched the Medline, CNKI, and WanFang database in computer (from January 2000 to August 2013) using the keywords of“everStick high-strength fiber composite resin, material performance, clinical application”in English and Chinese.
RESULTS AND CONCLUSION:The everStick high-strength fiber composite resin has the unique structure of IPN, and has the characteristics of simple operation, minimal y invasive, higher strength, strong cohesive force and reversibility. Because of the minimal y invasive, the everStick high-strength fiber composite resin can retain the healthy tissue of tooth with whole hog and provide the possibility for other therapeutic method because of the reversibility. At the present time, the everStick high-strength fiber composite resin has already been extended in the fields of post core, periodontal splint, orthodontic retainer, ful crown, adhesive fixed bridge, fixed bridge, inlay fixed partial dentures, dental implant restoration and the base in removable partial denture. But whether the material can be made into resin veneer and be used in color front teeth, for instance, the dental fluorosis, tooth discoloration after root canal therapy, tetracycline pigmentation teeth and hypoplasia of enamel, there is lack of comprehensive studies.
