Objective To evaluate the clinical effects of magnetic attachments in complete overdenture. Methods Casting method was used to fabricate Coping-Keepers for remained roots, and the patients were followed up for 6 months to check the effects of the overdentures retained with Magfit EX attachments. In the experimental group, 21 complete overdentures were made with 33 Magfit EX magnetic attachments for 18 patients. Eleven patients treated with traditional complete overdentures were selected to act as control. The retention force, aspect and comfortableness were subjectively evaluated by the patients of the both groups. Abutment status was observed and compared before and after cementation of the magnetic attachments by measuring periodontal index, including gingival index (GI), sulcus bleeding index (SBI) and bleeding on probing (BOP), etc. Masticatory function of patients in the both groups was measured at 3 time points: immediate, 3 months and 6 months after cementation. Results Patients in experimental group were more satisfied with complete overdentures made up of magnetic attachments than those in control group, especially in retention force and masticatory efficiency and aspect. Magnetic attachments can provide enough retention force for patients and greatly improved the masticatory efficiency and the abutment condition. The masticatory function was to be perfect and stable after 3-6 months. Furthermore, the mobility and periodontal index of most abutments improved after 6 months. Conclusion It is proved that magnetic attachments are effective to improve the function of complete overdentures, worthy to be used widely. It is suggested that the residual root and loosened tooth should be preserved furthest as possible in clinic.

Objective:To study the mechanism on extracellular signal-regulate kinases ( ERK) signal transduction by calcium influx initiated by combination of estrogen with calcium channels or estrogen re-ceptor in endometrial cancer cell Ishikawa. Methods: Confocal test was used to determine the relative calcium mobilization by stimulation of estrodiol together with and without the inhibition of ICI182780 and nifedipine. Western-blotting was used to detect the protein expression of phosphorylated ERK1/2 (P-ERK1/2) in the same condition. Results:The transient calcium flux initiated by 17β-estrodiol (E2) and a membrane-impermeable conjugate of estrogen and bovine serum albumin ( E2-BSA ) , and the calcium mobilization could be inhibited by ICI182780 and nifedipine in 1 min. In Ishikawa cells, phosphorylation of ERK1/2 was stimulated by E2 , and the phosphorylation could not be inhibited by E2 after the combination with ICI182780 in 5 min and in 30 min. The phosphorylation also could not be in-hibited by E2-BSA after the combination with nifedipine in 5 min, but in 30 min the phosphorylation was decreased. The phosphorylation of ERK by E2-BSA was decreased by the combination with nifedipine in 30 min. Conclusion:The transient calcium flux initiated by estrogen has an effect on the activation of ERK signal pathway in endometrial carcinoma cells.
