Comparison of the efficacy of vocal training and vocal microsurgery in patients with early vocal fold polyp

IntroductionVocal fold polyp is a benign proliferative disease in the superficial lamina propria of the vocal fold, and vocal microsurgery can improve the voice quality of patients with vocal fold polyp. In preliminary studies, we found that vocal training could improve the vocal quality of patients with early vocal fold polyp.ObjectiveThis study aimed to compare the efficacies of vocal training and vocal microsurgery in patients with early vocal fold polyp.MethodsA total of 38 patients with early vocal fold polyp underwent 3 months of vocal training (VT group); another 31 patients with early vocal fold polyp underwent vocal microsurgery (VM group). All subjects were assessed using laryngostroboscopy, voice handicap index, and dysphonia severity index, and the efficacies of vocal training and vocal microsurgery were compared.ResultsThe cure rates of vocal training and vocal microsurgery were 31.6% (12/38) and 100% (31/31), respectively. The intragroup paired-sample t-test showed that the post treatment vocal handicap index, maximum phonation time, highest frequency (F0-high), lowest intensity (I-low), and dysphonia severity index in both the VT and VM groups were better than those before treatment, except for the jitter value. The intergroup independent-sample t-test revealed that the emotional values of vocal handicap index (t = ? 2.22, p = 0.03), maximum phonation time (t = 2.54, p = 0.013), jitter (t = ? 2.11, p = 0.03), and dysphonia severity index (t = 3.24, p = 0.002) in the VT group were better than those in the VM group.ConclusionsBoth, vocal training and vocal microsurgery could improve the voice quality of patients with early vocal fold polyp, and these methods present different advantages.     

CT立体定向脑组织活检90例分析

目的：采用CT引导立体定向术对脑内病变进行活检，为诊断与治疗及其预后的评估提供组织学依据。材料与方法：使用CJF-I型脑立体定向系统和SOMATOMCR或SOMATOMPlus-4CT机，对90例脑肿瘤和非肿瘤性病变实施立体定向脑活检。结果：82例获得明确的病理诊断，占91．1％，无严重手术并发症和死亡。结论：CT立体定向脑活检术是安全的，具有很高的确诊价值。作者就手术操作技巧进行了详细探讨。     

Ca(OH)2预防再植牙根吸收的实验研究

目的：探讨Ca(OH)2预防再植牙根吸收的作用及机理。方法：选择健康家犬15只，每只犬选择6颗上颌前牙进行研究。6颗上前牙，口腔外自然干燥1小时，行牙再植术，2周后实验组用Ca(OH)2，对照组用氧化锌及牙胶尖进行根管充填，6个月后处死动物光镜观察比较2组的根吸收情况。结果：实验组根吸收为17．8％，对照组为46．7％。两组存在显著差异（P＜0．01）。结论：Ca(OH)2具有减少和预防再植牙根吸收的作用。     

薄层色谱中最佳展开剂配比的预测

本文根据薄层色谱中样品保留值,样品斑点展宽与多元流动相组成间的关系以及经修改了的复合形和改良单纯形寻优算法,初步建立了一套用计算机寻求最佳展开剂配比的方法体系,并运用本文建立的寻优方法确定了分离中成药戊己丸中有效成分的最佳展开剂配比。

组织工程韧带应用于前交叉韧带重建术的研究与进展

目的:总结和分析组织工程韧带代替自体和/或异体韧带(肌腱)重建前交叉韧带的实验研究进展。资料来源:应用计算机检索PubMed 1985-01/2005-12关于组织工程韧带重建前交叉韧带的文章,检索词“tissueengineering,anterior cruciate ligament”并限定文章的语种类为English。资料选择:对资料进行初审,纳入标准:组织工程韧带代替自体和/或异体韧带(肌腱)重建前交叉韧带研究的相关资料。排除标准:重复性研究。资料提炼:共收集到符合标准的文献30篇。资料综合:韧带的组织工程需要结构支架提供细胞生长的环境和基质;具有分化潜力的干细胞分布于支架,在生物和机械调制因子的作用下,增殖分化塑形为支架样,最后替代支架;组织工程特性生物材料在生长因子、细胞因子和营养成分的促进和生物力学因子的刺激下,干细胞能根据支架的性质改变细胞外的环境。结论:组织工程韧带重建前交叉韧带处于研究探索阶段,尚未进入到临床阶段。未来研究的目标是确证理想的培养媒体、机械刺激的力度、细胞种群和数量的选择,以及诱导组织工程韧带血管化的新技术。
