Objective To explore relationship between antinucleosome antibody and desease activity of systemic lupus erythematosus(SLE). Methods Serum antinucleosome antibodies were measured by ELISA in the 88 patients with SLE. The relationship among antinucleosome antibodies, disease activity ( evaluated using SLEDAI), anti-dsDNA antibody and complements was analyzed. Results Antinucleosome antibody was positive in 70 patients with SLE (79.5%). There were correlations between the antinucleosome antibody and SLE disease activity, anti-dsDNA antibody, complement C3, erythrocyte sedimentation rate. Conclusion Antinucleosome antibody is a relatively sensitive marker in diagnosing SLE and evaluating SLE disease activity.

OBJECTIVETo investigate the changes in the expression of phospholipase C-gamma1tyr783 (PLC-γ1tyr783) in the condylar cartilage of a young rat during functional mandibular protraction. This work also explores the function of PLC-γ1tyr783 in the rat mandibular condylar cartilage bone remodeling, which could provide experimental evidence for clinical bone ortho- pedic work.

METHODSA total of 60 four-week-old male Sprague-Dawley (SD) rats were used in this study. The rats were divided equally and randomly into experimental group and control group. The functional appliances that were fitted to the upper incisors of the animals in the experimental group were worn 24 h a day after the rats were fed for 7 d with homemade pellet feed. The animals in the experimental group, along with their matched controls, were sacrificed after 1, 3, 7, 14, 21, and 28 d. The bilateral condylar was fixed, decalcified, dehyded, and then conventional paraffin embedded. Immunohisto- chemistry of PLC-γ1tyr783 was applied to observe its express distribution and variation.

RESULTSThe expression of PLC-γ1tyr783 decreased gradually in the control group, which showed age-related changes (P > 0.05). On the 14th day, PLC-γ1tyr783 expres- sion in the experimental group was significantly higher than that in the control group. PLC-γ1tyr783 expression began to appear statistically and significantly different between the two groups (P < 0.01).

CONCLUSIONPLC-γ1tyr783 is involved in the bone remodeling process of the rat condylar cartilage after functional mandibular-protraction.

OBJECTIVEThis study aims to survey the cognition and acceptance of implant dentures among Chengdu residents in 2005 and 2013 and to comparatively analyze the differences and influencing factors.

METHODSA questionnaire was designed for this study. Its main content included basic demographics of respondents (gender, age, cultural level, and income level), cognition level of implant dentures (concept and main characteristics of implant dentures), main concern of respondents regarding implant dentures and medical institutions, and acceptance level of the price of implant dentures, among others. The sampling survey was carried out among Chengdu residents in 2005 and 2013 using the designed questionnaire. The results were then statistically analyzed.

RESULTSUp to 908 valid questionnaires in 2005 and 905 valid questionnaires in 2013 were obtained. The level of cognition of implant dentures was higher in 2013 than in 2005, and the correlation between cognition and cultural level and that between cognition and income level were both positive. However, the correlation between cognition and age was negative. The success rate for implant dentures and medical treatment technology of medical institutions were the factors that the respondents were mainly concerned with. The main methods for disseminating information on implant dentures were the internet, television, newspapers, magazines, and introduction by friends.

CONCLUSIONWith the development of the society's economy and the improvement of culture and income level of Chengdu residents, the cognition and acceptance level of implant dentures have gradualy increased. Meanwhile, health education and medical technology still need to be strengthened.

Objective:To explore the relationship between wearing of functional appliance and systemic metabolism of PGE2 in the blood of growing rats.Methods:54 male Wistar rats aged 4-weeks were randomly divided into 3 groups(n =18):Daytime group,all-day group and control group.Self-guided functional appliance was made for mandible advancement of the rats in the 2 experimental groups.One week after appliance wearing,rats were sacrificed at the corresponding time points and blood in femoral artery was taken. PGE2 levels in the blood samples were measured,data were analysed by cosine equation.Results:Hypothesis was true in the control group(P ＜0.05),and was not true in both 2 experimental groups(P >0.05).Conclusion:PGE2 level in rat blood is circadian rhyth-mic,wearing of functional appliance made may disturb the rhythm.

BACKGROUND: Twin-block appliance has been confirmed to efficiently change hard tissue and the profile of soft tissue.Whether a linear relationship exists between soft tissue and hard tissue changes remains unclear.OBJECTIVE: To evaluate the face convexity changes of soft and hard tissues after Twin-block appliance therapy and compare with controls.METHODS: Thirty-one class Ⅱ division 1 malocclusion subjects with hand-wrist radiographs in FG-G stage were selected.Among the 31 patients,17 received Twin-block appliance therapy,serving as experimental group,and the remaining 14 subjects abandoned treatment,serving as control group.Cephalometric radiographs of each included subject were taken prior to and after treatment or observation.Face convexity of soft and hard tissues,as well as the face convexity changes,was compared between the experimental and control groups.Linear regression equation was employed to analyze the linear association between soft-and hard-tissue changes.Regression equations of experimental and control groups were compared.RESULTS AND CONCLUSION: Prior to and after Twin-block appliance therapy,a significant correlation existed between the position changes of superior and inferior alveolar sockets relative to the nose and mandible,and the position changes of upper and lower lip pits relative to the nose and mandible,i.e.,there was a linear correlation between A-E change and Ss-E change,and between B-E change and Si-E change.The largest Pearson's correlation coefficient(0.839)appeared between Si-E change and B-E change,indicating the best correlativity between these two changes.Statistical analysis revealed that the linear equations of face convexity changes of soft and hard tissues after Twin-block appliance therapy were Si-E=0.745 B-E,Ss-E=0.276 A-E.These linear equations would be helpful to explain mandible growth and face convexity change after Twin-block appliance therapy and predict the prognosis of face convexity change.

AIM:To explore the distance from the labrale superius and inferius of the soft tissue profile in early permanent dentition with normal occlusion to the esthetic line (E line) and the proportion among each section of E plane. METHODS: Thirty Han teenagers with normal occlusion including 15 males and 15 females with the average age of 11.5 years were selected from January 2000 to December 2005. They were examined cephalometrially to measure the distance between labrale superius (Ls) and E, labrale inferius (Li) and E, and the mean values and standard deviation of prenasale (Prn)-Ls/distance between Prn and pogonion (Pg') of soft tissue, Ls-Li/distance between Prn and Pg' and Li-Pg'/distance between Prn and Pg'. RESULTS: ①Distance of Ls-E and Li-E: Ls-E and Li-E of normal occlusion were (0.083 3?0.920 8) mm and (0.621 7?1.124 6) mm. ②Proportion of each segment to the distance of Prn and Pg': Prn-Ls/Prn-Pg', Ls-Li/Prn-Pg' and Li-Pg'/Prn-Pg' were 0.413 8?0.022 3, 0.200 9?0.023 1, 0.385 7?0.022 8, respectively. CONCLUSION: E plane analysis is a convenient and effective method in the diagnosis of soft tissue in clinic. The Ls and Li are exactly on the E plane in normal occlusion and the ratio of three sections is 2∶1∶2.

Objective This study simulated clinical implant surgery using squeeze technique by establishing a rational animal model.We investigated the microscope image in order to observe the agglutination of the cancellous bone after being compressed.Methods The cancellous bone in condyles of dog femur had been chosen as the experimental position,the implant holes were prepared using squeeze technique according to different compressing extent(0,0.6,1.2,2.0mm),and then the corresponding implants were inserted into them.After different healing periods(1 week,2 weeks,4 weeks,12 weeks),the mongerl dogs were sacrificed and the hard tissue slices were made,then the architecture of the cancellous bone was observed using microscope.Results The architecture of the cancellous bone was changed obviously by squeeze technique in 1 week,2 weeks and 4 weeks hard tissue slices.After being compressed,the bone trabecula around implants was compact.Conclusion The clinical implant surgery using squeeze technique helps improve peri-implant bone density,which is good for obtaining primary stabilities of implants.
