OBJECTIVEThis study aimed to investigate the effects of different tooth preparations on the fracture strength and pattern of failure of teeth with severe wedge-shaped defect restored with post and core crowns.
METHODSAccording to whether the teeth above the wedge-shaped defect was removed (represented by B) or not (represented by A), the ferrule next to the wedge-shaped defect was prepared (represented by D) or not (represented by C), the cast post-and-core was chosen (represented by E) or glass-fiber post and resin core was chosen (represented by F). A total of 64 human mandibular premolar teeth were randomly divided into 8 groups: A1-1 (A + C + E), A1-2 (A + C + F), A2-1 (A + D + E), A2-2 (A + D + F), B1-1 (B + C + E), B1-2 (B + C + F), B2-1 (B + D + E), B2-2 (B + D + F), each group 8 teeth. All the teeth were prepared and restored accordingly and then mounted on an electronic pressure universal testing machine. The maximum fracture strength and the patterns of failure were recorded.
RESULTS1) The fracture strength of Group A1-1 > that of Group B1-1, Group A1-2 > Group B1-2, Group B2-1 > Group B1-1, and Group B2-1 > Group B2-2 with significant differences (P < 0.05). 2) The patterns of repairable fracture in Group A1-2 and B1-2 were both 37.5%, and that of the other groups were 0. Furthermore, the difference was significant, and Group A1-2 and B1-2 were higher than other groups.
CONCLUSIONThe maintenance of the overhang above the severe wedge-shaped defect aid in the improvement of the fracture strength of the tooth restored with post and core crown. The ferrule of the wedge-shaped defect is not recommended to be prepared. Furthermore, the glass-fiber post and resin core is favorable for the re-repair of the teeth than the cast post and core.

Bursting is an important firing mode of neurons. To propose a stochastic model of bursting spike train, the interspike interval (ISI) characteristics of single-spiking train and bursting spike train were analyzed and compared. In contrast with the exponential distribution of ISI in single-spiking train, normal distribution is supposed to be the ISI model of bursting spike train. Simulated neural spike trains were produced to investigate the spectrum features of the ISI model. The results showed that: (1) bursting spike train with normally distributed ISI held a low-pass spectrum while the spectrum of single-spiking train was flat; (2) the coefficient of variation of ISI in bursting train decided the bandwidth of its low-pass spectrum. Then neural activities from anesthetized rodent were used to check the validity of the model. 10 simultaneously recorded bursting spike trains and 10 single-spiking trains were selected during anesthesia and after pure-oxygen-washout period respectively. The spectrograms of these neural spike trains were analyzed and the results were matched with our mathematical model. It is believed that the bursting spike train model established in this paper will help to theoretically study the statistical characters of neural spike train and to add mathematical foundation in neural coding schemes.

[Objective]To analyze the prognostic factors of resectable acral melanoma patients ,then develop a novel prognostic model and examined its prognostic value.[Methods]The study retrospectively analyzed clinicopathological characteristics and inflam?matory markers of 232 acral melanoma patients who underwent radical surgical resection between 2000 and 2011 at the Sun Yat-sen University Cancer Center. Kaplan-Meier curves were plotted to estimate overall survival. Significantly predictive factors were identified by multivariate Cox regression analyses and a prognostic model based on these variables was constructed to predict survival.[Results]Cox regression analysis revealed that age,lactic dehydrogenase(LDH),stage,globulin(GLB)and C-reactive protein (CRP)were independently related to survival. After computing these scores ,patients were classified into three risk groups. The new prognostic model identified three categories of patients with different prognoses(P<0.001)and significantly stratify patient prognosis in different tumor stages. The 5-year survival rate was 42.9%,25.7%,and 3.7%in groups 1,2,and 3,respectively. The AUC of new prognostic model is 0.664(95%CI:0.599-0.724).[Conclusion]Age,LDH,stage,GLB and CRP were independently related to survival in our study population,and the prognostic model is useful to stratify patients into different risk groups and it is a useful complement to AJCC staging for Asian patients with acral melanoma.
