OBJECTIVE: To explore the applicability of integration between three-dimensional (3D) facial and dental data to evaluate the nasolabial morphology variation before and after the cross-arch fixed restoration of the maxillary implant-supported prostheses. METHODS: Twelve patients (4 women and 8 men), mean age (54.82±5.50) years (from 45 to 62 years) referred to the Department of Oral Implan-tology, Peking University School and Hospital of Stomatology, were selected and diagnosed with edentulous maxilla. For all the patients, 4 to 6 implants were inserted into the maxilla. Six months later, the final cross-arch fixed prostheses were delivered. The 3D facial images were collected before and after the final restoration. The 3D data of prostheses were also captured. All the 3D data were registered and measured in the same coordinate system. Then the displacement of all the landmarks [cheilion left (CHL), cheilion right (CHR), crista philtri left (CPHL), crista philtri right (CPHR), labrale supe-rius (LS), subnasale (SN), stomion (STO), upper incisor (UI), upper flange border of the prostheses (F-point, F)], and the variation of the distances between these landmarks (SN-LS, CPHR-CPHL, CHR-CHL, LS-STO) were analyzed and compared. RESULTS: The consistency test among three measurements of the length of F-SN indicated that the integration method of the dental prostheses and soft tissue had the good repetitiveness, ICC=0.983 (95%CI: 0.957-0.995). After wearing the final cross-arch maxillary implant-supported prostheses, all the landmarks on the soft tissue moved forward. The nasal base area changed minimally, and the shift of SN in the sagittal direction was only (0.61±0.44) mm. But the sagittal shift of LS was (3.12±1.38) mm. In the vertical direction, SN, LS, CPHL, and CPHR moved upward. But STO, CHL, and CHR moved downward a little. Except for the slight decrease of the length of philtrum (SN-LS), the length of CHL-CHR, CPHL-CPHR, and the height of upper lip were increased together (P < 0.01). In the direction of Z axis, the strong correlations were found not only between the movements of SN and F (r=0.904 3) but also between the movements of LS and UI (r=0.958 4). CONCLUSION The integration method of 3D facial and dental data showed good repetitiveness. And the strong correlations between the landmarks of prostheses and nasolabial soft tissue in the sagittal direction were found by this new method.

OBJECTIVE: To investigate the influence of demographic and clinical characteristics, stress, and coping style on disease self-management in children and adolescents with type 1 diabetes. METHODS: A cross-sectional survey was performed to select 149 children and adolescents with type 1 diabetes (aged 8-20 years). Related data were collected using the questionnaires and scales on general information, diabetes self-management, perceived stress, and coping style. RESULTS: Of the 149 children and adolescents, 37(24.8%) had high stress. Compared with the school-aged children, the adolescents had higher stress level and were more likely to present with negative coping style (P<0.05). The multiple linear regression analysis showed that the children whose mothers had an educational level at or above senior high school, who had a low stress level, and who adopted positive coping measures had a higher level of diabetes self-management (P<0.05). CONCLUSIONS Nearly a quarter of the children and adolescents with type 1 diabetes have a high stress level. When delivering the education on diabetes self-management to children and adolescents, healthcare workers should focus on the families whose mothers have an educational level at or below junior high school. Strategies should aim at reducing stress by encouraging positive coping styles.

Objective To investigate the effect of dopamine and acetylcholine on the expression of iNOS in rat primary glia stimulated with the bacterial endotoxin lipopolysaccharide (LPS). Methods We cultured the rat primary glia, pretreated by dopamine and acetylcholine for 30 min, then challenged by LPS for 12 h and 24 h, isolated total RNA for RTPCR , did cell immunohistochemisry, respectively to observe the change of iNOS at transcription and translation levels,measured nitrite in the culture medium using Griess method to assess endogenous synthesis of NO. Results Acetylcholine had no effect on the transcription of iNOS, otherwise dopamine could inhibit it, both of dopamine and acetylcholine could reduce the expression of iNOS protein and the production of NO. Conclusion dopamine and acetylcholine inhibited the expression of iNOS in primary glia challenged by LPS in different ways.

OBJECTIVETo evaluate the status of cell differentiation in nasal NK/T cell lymphomas.

METHODSThe clinical data of 88 cases of NK/T cell lymphomas were collected. Antibodies to the following antigens were used in the immunohistochemical study: T cell differentiation antigens (CD3epsilon, CD5 and CD1a); NK cell associated antigens (CD56, CD57) and antibodies of CD34 and CD38.

RESULTS(1) Clinicopathology: clinically, frequently involved sites were the nasal cavity and the pharynx. Ulceration and erosion of the mucosa were common signs. Pathologically, diffuse infiltration of the tumor cells was observed in 68 of 88 (70.45%) cases of nasal NK/T cell lymphomas. In 71 (80.68%) cases infiltrated cells were predominantly medium to large sized; (2) Differentiation status of tumor cells: the tumor cells expressed CD3epsilon in 78/88 (88.64%); CD5 in 56/88 (63.63%), CD56 in 25/88 (28.41%) and no positivity for CD1a, CD57, CD34 and CD38.

CONCLUSIONStatus of tumor cell differentiation in nasal NK/T cell lymphoma may have passed the stage of progenitor cell differentiation but not yet to the stage of mature T or NK cells.
