The objective of this study is to investigate the effect of the ultrasound-microbubble technique in nuclear factor kappa B(NF-κB) decoy oligodeoxynucleotide(ODN) transfection in the gingival tissue in mice. The 6-FAM-labeled scrambled decoy ODN with microbubbles was applied to the periodontal tissue in 8-week-old male C57BL/6J mice by ultrasound radiation at low(LUM-Sc) and high(HUM-Sc) intensities to optimize the transfection condition of the ultrasound-microbubble *** inspections were performed two hours after transfection to compare the expression with that in the sham-operated group without ultrasound radiation(A-Sc). Then, an NF-κB decoy was transfected into the periodontal tissue using the highintensity ultrasound-microbubble(HUM-NF) technique to examine the anti-inflammatory effects of the decoy ODN. Western blot analysis was performed to investigate the expression of interleukin(IL)-1β, IL-6 and intercellular adhesion molecule-1(ICAM-1)in the gingival tissues in the HUM-Sc, the HUM-NF and control groups. The fluorescence microscopy results showed that the fluorescent intensity in the periodontal tissues in the LUM-Sc and HUM-Sc groups was significantly higher than that in the A-Sc and the control groups. The fluorescent intensity in the HUM-Sc group, especially in the gingival connective tissue,was the highest of all groups. Western blot analysis indicated that the protein expression levels of IL-1β, IL-6 and ICAM-1 in the HUM-NF group were significantly lower than those in the HUM-Sc and the control groups. These findings suggest that the high-intensity ultrasound-microbubble technique is an effective tool for decoy transfection into the periodontal tissue.

The goal of this study was to assess the effect of the intermittent combination of an antiresorptive agent （calcitonin） and an anabolic agent （vitamin D3） on treating the detrimental effects of Type 1 diabetes mellitus （DM） on mandibular bone formation and growth. Forty 3-week-old male Wistar rats were divided into four groups： the control group （normal rats）, the control C＋D group （normal rats injected with calcitonin and vitamin D3）, the diabetic C＋D group （diabetic rats injected with calcitonin and vitamin D3） and the diabetic group （uncontrolled diabetic rats）. An experimental DM condition was induced in the male Wistar rats in the diabetic and diabetic C＋ D groups using a single dose of 60 ***-1 body weight of streptozotocin. Calcitonin and vitamin D3 were simultaneously injected in the rats of the control C＋D and diabetic C＋D groups. All rats were killed after 4 weeks, and the right mandibles were evaluated by micro-computed tomography and histomorphometric analysis. Diabetic rats showed a significant deterioration in bone quality and bone formation （diabetic group）. By contrast, with the injection of calcitonin and vitamin D3, both bone parameters and bone formation significantly improved （diabetic C＋ D group）（P 〈 0.05）. These findings suggest that these two hormones might potentially improve various bone properties.

目的研究下颌逐步前伸过程中上气道形状的变化规律,了解藉改变颌位而改善通气的疗法的机制。方法对14例无鼾成年男性,使用特制口腔装置将下颌依次前伸,从初始咬合位0(F0),前伸50%(F50)、75%(F75),至前伸最大量100%(F100)。在此4个位置上行上气道磁共振扫描。测量和分析上气道各段轴截面矢向径/横向径的比值、矢向径和横向径相对于初始位置的改变百分率。结果随下颌逐步前伸,上气道轴截面矢向径/横向径的比值依次减小(P=00001),横向径变化率逐步增加(P=00023),而矢向径变化率的变化无统计学意义。结论在下颌逐步前伸过程中,上气道形状有更加横向扁圆的倾向,说明下颌前伸主要横向扩张上气道。
