ABSTRACT
Objective:To compare the fit of Co-Cr basal crowns fabricated by three kinds of technology. Methods:18 laser cured resin dies were divided into A, B and C groups(n=6) randomly. Co-Cr basal crowns of group A, B and C were made by traditional casting technology, CAD/CAM cutting metal technology and direct metal laser sintering technology( DMLS) respectively. The crowns were cemented to the corresponding dies and the basal crowns and dies were embedded in methyl acrylic. The thickness of the cement layer of the samples was measured under a stero microscope. Data were analyzed with SPSS13. 0 statistical software. Results:Marginal gap of group A, B and C was (66.08 ±3.90) μm, (29.21 ±3.31) μm and (24.96 ±2.99) μm respectively(P0. 05). Conclusion:DMLS technology may make the best marginal fit, CAD/CAM and DMLS technology may pro-duce better internal fit. The marginal fit and the internal fit of the crowns prepared by the 3 methods can meet the clinical requirements.
ABSTRACT
Objective To discuss the influence of special nursing intervention for the quality of life of outpatients with chronic pelvic inflammatory disease. Methods Divided 80 patients into the observation group and the control group randomly, there were 40 cases in each group. Routine nursing, treatment and disease-related lecture were used in both the groups, while the combined therapy of Chinese and Western medicine was used in the observation group in addition. Evaluated the quality of life and the effects of treatment by the World Health Organization′s quality of surviving chart between the two groups after 3-month intertention and 6-month follow-up. Results The scores of quality of environment field, physiology field ,psychological field, sociological field, independence field and mental field in the observation group was (70.33+16.85 ) (70.38+18.80), (71.43+18.28),(70.13+19.08), (73.10+17.70) and (75.38+7.30) respectively, while in the control group was (61.38+16.17), (56.70+17.69), (43.13+19.77), (55.00+19.08), (53.75+16.45) and (49.80+17.26) respectively, the difference between the two groups was significant, the t values were 2.424-8.631, P < 0.05. The effective rate of treatment in the observation group was 95.00%(38/40), while in the control group was 82.5%(33/40), the difference was significant, U=2.507, P < 0.05. Conclusions Special nursing intervention can promote the quality of life ,effects of treatment and the satisfaction of treatment in outpatients with chronic pelvic inflammatory disease, improve their psychological state and the compliance.
ABSTRACT
<p><b>OBJECTIVE</b>To compare the difference of the clinical efficacy in treatment of nervous tinnitus of kidney deficiency between the combined therapy of Zhuang medicine at Qineihuan point combined with the conventional acupuncture and simple conventional acupancture.</p><p><b>METHODS</b>Sixty patients were randomized into an observation group and a control group, 30 cases in each one. In the control group, the conventional acupuncture was applied to Taixi (KI 3), Zhaohai (KI 6), Tinggong (SI 19) and Waiguan (TE 5), etc. and the needles were retained for 30 min. In the observation group, on the basic treatment as the control group, Zhuang medicine acupuncture at Qineihuan point was added. The treatment was given once every day, 10 treatments made one session and there were 2 days of interval between the sessions. In 3 sessions of treatment, the changes of tinnitus were observed and the clinical efficacy was evaluated.</p><p><b>RESULTS</b>After treatment, tinnitus score and tinnitus grade were all improved as compared with those before treatment in the two groups (all P<0. 05) and the results in the observation group were better than those in the control group (all P<0. 05). The curative and remarkably effective rate was 63. 3% (19/30) and the total effective rate was 93. 3% (28/30) in the observation group, better than 30. 0% (9/30) and 73. 3% (22/30) in the control group (both P<0. 05).</p><p><b>CONCLUSION</b>The combined therapy of Zhuang medicine at Qineihuan point and conventional acupuncture achieves the better efficacy on nervous tinnitus of kidney deficiency as compared with the simple conventional acupuncture.</p>
