PURPOSE: To improve the clinical effects of complete denture use and simplify its clinical application, a digital complete denture restoration workflow (Functional Suitable Digital Complete Denture System, FSD) was proposed and preliminary clinical evaluation was done. MATERIALS AND METHODS Forty edentulous patients were enrolled, of which half were treated by a prosthodontic chief physician, and the others were treated by a postgraduate student. Based on the primary impression and jaw relation obtained at the first visit, diagnostic denture was designed and printed to create a definitive impression, jaw relation, and esthetic confirmation at the second visit. A redesigned complete denture was printed as a mold to fabricate final denture that was delivered at the third visit.To evaluate accuracy of impression made by diagnostic denture, the final denture was used as a tray to make impression, and 3D comparison was used to analyze their difference. To evaluate the clinical effect of FSD, visual analogue scores (VAS) were determined by both dentists and patients. RESULTS: Two visits were reduced before denture delivery. The RMS values of 3D comparison between the impression made via diagnostic dentures and the final dentures were 0.165 ± 0.033 mm in the upper jaw and 0.139 ± 0.031 mm in the lower jaw. VAS ratings were between 8.5 and 9.6 in the chief physician group, while 7.7 and 9.5 in the student group; there was no statistical difference between the two groups. CONCLUSION FSD can simplify the complete denture restoration process and reduce the number of visits. The accuracy of impressions made by diagnostic dentures was acceptable in clinic. The VASs of both dentists and patients were satisfied.

Objective To establish A1E3 and B1C4 monoclonal antibody-based ELISA for detecting circulating antigen of Schistosoma japonicum and explore its application value in the field. Methods The characteristics of A1E3 and B1C4 monoclonal antibodies were analyzed by SDS-PAGE and Western blotting. The SEA-based ELISA was used to evaluate the titers of A1E3 and B1C4. The orthogonal test was used to determine the best concentration of coating antibody B1C4 and optimal working concentra-tion of A1E3-HRP. Under the optimal conditions,the serum samples of 20 acute schistosomiasis cases,46 chronic schistosomiasis cases,and 20 control sera were tested to evaluate its detection sensitivity and specificity. Seventy-two antibody positive serum sam-ples from Jiangling County of Hubei Province were detected and compared to a commercially available ELISA kit,to evaluate the detection effects of this method. Results The results of SDS-PAGE demonstrated that the purified A1E3 and B1C4 contained a clear heavy chain with molecular weight of 88 000 and 52 000 respectively and had the same light chain with molecular weight of 20 000;while Western blotting demonstrated that A1E3 and B1C4 could be recognized by SEA and serum samples of acute schis-tosomiasis cases. The SEA-based ELISA demonstrated the titers of B1C4 and A1E3 were 1∶105 and 1∶30 000,respectively. The serum samples from all the acute cases and 86.9% of the chronic cases showed a positive reaction. All of the control sera from healthy persons gave a negative response. The positive rates of the double monoclonal antibody ELISA and commercial ELISA for detecting the circulating antigen were 45.8%and 43.1%respectively,and there was no significant difference between the results of the two methods. Conclusion A1E3 and B1C4 monoclonal antibody-based ELISA is established successfully. It exhibits a high sensitivity and specificity in detecting circulating antigen of Schistosoma japonicum.

Objective:To investigate the relationship between thyroid iodine uptake rate, 99Tc m imaging and treatment of Graves' hyperthyroidism with 131I. Methods:132 patients with Graves' hyperthyroidism were analyzed retrospectively. According to the difference of thyroid 24-hour iodine uptake rate, they were divided into group A (≤50%), group B (50%-80%) and group C (≥80%). According to the trend of iodine uptake rate curve, they were divided into peak advance group (6 h/24 h iodine uptake rate ratio >1) and non-peak advance group (6 h/24 h iodine uptake rate ratio≤1). Thyroid 99Tc m imaging was divided into three groups according to quality, including group 1 (≤30 g), group 2 (30-60 g) and group 3 (≥60 g). The therapeutic effects of 131I in different types of patients were compared. Results:132 patients were followed up for 6 months after the first 131I treatment. The total effective rate, total cure rate and uncured rate were 88.6%(117/132), 78.0%(103/132), 22.0%(29/132), respectively. The serum thyroxine levels of patients with different 24-h iodine uptake rates in the three groups after treatment were significantly lower than those before treatment ( P<0.05). The lower the 24-h iodine uptake rate of thyroid, the more significantly the serum total triiodothyronine (TT3), total triiodothyronine (TT4), free triiodothyronine (FT3) and free thyroxine (FT4) levels decreased after treatment, the more obvious the increase of thyroid stimulating hormone (TSH), and the more obvious the treatment effect ( P<0.05). The cure rate (13/29, 44.8%) in the peak advance group was significantly lower than that in the non peak advance group (90/103, 87.4%), with statistically significant difference (χ 2=23.899, P<0.001). There was significant difference in the cure rate among the three groups with different thyroid 99Tc m imaging quality (χ 2=15.502, P<0.001). Conclusions:With the increase of thyroid mass, the higher the 24-h iodine intake rate, the more obvious the peak shift, the lower the cure rate, the higher the non-healing rate, and the lower the incidence of hypothyroidism.
