Chinese Journal of Tissue Engineering Research 2010;14(3):496-499
BACKGROUND: Ceramic crown porcelain fracture is wide in clinic. The method of repairing single crown porcelain fracture is simple and effective, but it is difficult for ceramic fixed bridge, especially individual teeth porcelain fracture on the long bridge. There is no report concerning prosthesis of partial crown with aperture of neighboring surface. OBJECTIVE: To lessen suffering and economic burden of the patient with cracking of porcelain on the fixed bridge, to decrease the chanciness and manufacture procedure of removing the porcelain fixed bridge, to discuss the feasibility of prosthesis of partial crown with aperture of neighouring surface.METHODS: By preparing tooth at damaged pontic or retainer of the porcelain fixed bridge in oral, shaping "core" retention form which analogy "keyway" form at both of retainers, and then make the porcelain partial crown with aperture of neighboring surface. RESULTS AND CONCLUSION: We followed up 27 patients that porcelain-fused-to-metal (PFM) with cracking of porcelain using partial crown with aperture of neighboring surface to repairing for 2-3 years. The prosthesis was strong; the edge of prosthesis was close together, without exposing metal or cracking of porcelain, gingival had no redness at the edge of crown and pontic. Patients feel good, chewing was normal. These suggested that the prosthesis of partial crown with aperture of neighboring surface is an effective method for restoring the fixed bridge with cracking of porcelain, with less risk, low cost and simple operation.

Objective To investigate the influencing factors related to the complications of esophageal foreign body in children. Methods Data of 150 children with esophageal foreign bodies admitted to Xi'an Children' s Hospital from January 2012 to June 2015 were included in the retrospective analysis. Related clinical variables ( gender, age, location, time, size, sharpness, quality, and severity of complications) were statistically analyzed. Results Spearman correlation analysis showed that the age of children was negatively correlated with esophageal foreign body complications (r=-0. 187, P=0. 022), incarceration time ( r=0. 456, P<0. 001) , sharpness ( r=0. 384, P<0. 001) and quality ( r=0. 234, P=0. 004) was positively correlated with the incidence of complications. Non?conditional Logistic regression analysis for polytomous ordinal response showed that incarceration longer than 8 h yielded complication risks 9. 507 times as much as that less than 8 h ( 95%CI:2. 982?30. 309) . Obtuse or sharp foreign body yielded risk 142. 751 times as smooth foreign body did (95%CI:13. 736?1483. 562). Conclusion Incidence and severity of complications of esophageal foreign body in children are closely related to the age of the children, incarceration time and the degree of sharpness. For patients of less than 1 year old, incarceration for more than 8 hours, with an obtuse or sharp foreign body, early diagnosis and treatment is essential.

Objective To detect the expression of T cell immunoglobulin mucin 3 (Tim-3) and its relationship with Th17/Treg cytokine isolated from peripheral blood mononuclear cells (PBMCs) and broncho-alveolar lavage fluids (BALF) cells in the asthmatic murine model and to investigate the role of Tim-3 in the occurrence and development of the asthmatic inflammation. Methods The asthmatic murine model was established by the method of ovalbumin (OVA) injection and inhalation. The mice were randomly divided into 2 groups: the normal control and the asthma group. PBMCs and BALF cells in each group were collected. Expression of Tim-3 mRNA was detected by the real-time PCR assay. Levels of CD4+IL-17+ and CD4+CD25+FoxP3+, reflecting expressions of Th17 and Treg respectively , were detected by flow cytometry. The correlationbetween Tim-3 and Th17/Treg level was analyzed. Results Contrast with the normal control group, the expression of Tim-3 mRNA in PBMCs and BALF cells in the asthma group increased significantly (P < 0.01). OVA sensitization and challenges resulted in the increased CD4+IL-17 production and the decreased CD4+CD25+Foxp3+in PBMCs and BALF cells compared with those in the normal control group (both P < 0.05). The ratio of Th17/Treg significantly increased in asthma group (P < 0.05). Tim-3 mRNA expression in PBMCs and BALF cells was positively correlated with CD4+IL-17+ level and Th17/Treg ratio , respectively , and was negatively correlated with CD4+CD25+Foxp3+ level. Conclusions Tim-3 mRNA level in PBMCs and BALF cells in the asthma group was increased , indicating that Tim-3 might take part in the occurrence and development of asthmatic inflammation and has a very close relationship with the Th17/Treg imbalance.
