Clinico-statistical and biometric evaluation of the effectiveness of the Fr?nkel method for the treatment of distal bite]

84 patients with distocclusion were treated with type I and type II function regulators for two years. Correlation analyses showed that the dental arch width and length as well as the apical base are positively influenced and the there are significant correlations between treatment expenditure and treatment duration, between treatment duration and the summary changes in measuring data, and between treatment expenditure and the changes in measuring data. Almost recurrence-free, positive therapeutical results were achieved. Fr?nkel's method is recommended for practice.     

One-Year Follow-up of Duodenal Ulcers after 1-Wk Triple Therapy for Helicobacter pylori

Objective : to study the ulcer recurrence rate of Helicobacter pylori-positive duodenal ulcers at 1 yr after eradication of the bacteria by triple therapy. Method : Patients with H. pylori-positive duodenal ulcers were randomized to receive either triple therapy for 1 wk plus omeprazole for 4 wk (THple+OMP) (n = 78), or omeprazole alone (OMP) for 4 wk (N = 77). Patients were followed up every 3 months for symptom enquiry. At 1 yr, all asymptomatic patients were invited to attend for gastroscopy. Results : At 8 wk, 16 patients in the OMP group and four in the Triple+OMP group had an ulcer. During the 1-yr period, 12 patients in the OMP group and no patient in the Triple+OMP group developed symptomatic ulcers. At follow-up endoscopy at 1 yr, another 10 ulcers were detected in the OMP group and two in the Triple+OMP group. Fifteen patients in the OMP group and 13 in the Triple+OMP group were lost to follow-up. In total, ulcers were de-tected in 39 of 61 (64%) assessahle patients in the OMP group, and in six of 65 (97o) assessahle patients in the Triple+OMP group after I yr (χ² test: p < 0.001). Of the patients whose H, pytori were successfully eradicated hy Triple+OMP at 8 wk, 90% remained H. pylori negative at 1 yr. Conclusion : Triple therapy for 1 wk eradicates H, pylori infection and significantly reduces duodenal ulcer relapses.     

Diagnosis and therapy of the distal bite]

Of all the malocclusions, distocclusion is most frequently associated with functional disorders. 60% of the patients suffered from diseases of the upper respiratory tract. A classification into 9 forms is suggested (fig.). Treatment with the Fr?nkel type I and type II function regulators is performed in the active phase of growth at the end of the period of deciduous dentition and during the early period of mixed dentition. The rectification of the morphological and functional disorders that is simultaneously achieved justifies the recommendation of this treatment for practice.     

重组腺病毒bcl-xs基因对人卵巢癌裸鼠移植瘤作用的研究

目的 观察重组腺病毒bcl-xs基因（adv-bcl-xs基因,简称bcl-xs基因）对人卵巢癌裸鼠移植瘤的生长抑制和荷瘤裸鼠生存率的影响。为卵巢癌的基因治疗提供实验基础。方法 采用以复制缺陷型腺病毒bcl-xs基础感染的人胚肾细胞,使bcl-xs基因对NUTU-19细胞的生长抑制作用并检测其病毒滴度后,将bxl-xs基因导入人卵巢癌裸鼠移植瘤中,观察bcl-xs基因对腹水的生长抑制作用,计算裸鼠的生存时间,并观察bcl-xs基因对裸鼠全身和局部的毒副作用。电镜观察bcl-xs基因的病毒颗粒,以免疫细胞化学染色测定bcl-xs基因表达情况。结果 bcl-xs基因可在人胚肾细胞内扩增,对NUTU-19细胞有抑制和杀伤作用。并在裸鼠体内呈过度表达,使裸鼠腹水形成的时间由5-10d延长至11-23d,裸鼠平均生存时间由24d延长至39d,bcl-xs基因对裸鼠全身和局部无明显毒副作用。结论 bcl-xs基因导入人卵巢癌裸鼠移植肿瘤,能延缓腹水形成,延长裸鼠的生存时间,为卵巢癌的基因治疗提供了一种新方法。
