关于症状自评量表合成常模与元分析的讨论

以症状自评量表为工具,以Stata SE12.0和SPSS19.0为主要统计工具,模拟合成量表常模的过程,并进行同质性检验、亚组分析、回归分析和发表偏倚分析。结果表明有4个因子拒绝同质假设,元分析的同质性检验结果拒绝同质性假设,亚组分析和回归分析无法解释其异质性来源,发表偏倚检验结果表明所列文献无发表偏倚。进而得出结论:1.以文献上的二手数据为基础合成的大学生SCL-90常模在统计上极有可能是无效的,从程序上讲也是不可靠的;2.已有的元分析报告中,SCL-90各因子得分与常模比较得出的效应量在统计上是无效的。     

大袋蛾核型多角体病毒,病状及毒力的生物测定

报道了对大袋蛾核型多角体病毒、病状的观察。林间因感染大袋蛾核型多角体病毒而死亡的幼虫可分为两类：一类为纯病毒感染，另一类为病毒和细菌混合染。用不同浓度的大袋蛾核型多角体病毒感染大袋蛾卵，得多角体浓度与死亡率的直线回归方程：ｙ＝０．７８＋０．８２３ｘ，ＬＣ５０为１．１８×１０＾５ＰＩＢ／ｍＬ。用１０＾５，５×１０＾５，１０＾６ ＰＩＢ／ｍＬ感染卵，得感染时间与死亡率的关系和ＬＴ５０，分别为：ｙ＝６．

The impact of long-term botulinum toxin injections on symptom severity in patients with spasmodic dysphonia

Injection of botulinum toxin (BT) into the muscles of the larynx is an effective treatment for the symptoms of spasmodic dysphonia (SD). To date, however, there have been no studies that have used blinded raters to assess the efficacy of BT injections on overall symptom severity in a cohort of SD patients followed over a prolonged period. In this study, 102 subjects with SD were treated with serial BT injections for up to 2 years. Voice recordings were obtained at several time points during treatment and were played to a panel of expert and novice listeners who rated them based on overall symptom severity in a single-blind fashion. Subjects demonstrated significant improvement over baseline at all time points. In addition, patients showed a sustained responsiveness to therapy over time. These results provide support for the efficacy of serial BT injections for SD and suggest that successful treatment may depend, in part, on patients' early recognition of returning symptoms.

The effects of premenstrual syndrome (PMS) on the female singer

A review of the medical literature concerning the psychological, physical, and vocal effects of premenstrual syndrome reveals a wide range of significant effects for the female singer and a larger number of proposed treatments. A survey was conducted to evaluate the frequency and severity of 67 general physical and psychological symptoms and 20 vocal symptoms experienced by 104 female singers. The variables of age, menstrual history, voice type, and performing experience were examined. The average number of general symptoms was 33 and the average number of vocal symptoms three. The most frequently reported general symptom was abdominal bloating, while the most frequently reported vocal symptom was difficulty in singing high notes. The subjects reported that symptoms occurred with moderate regularity and severity. At age 35 symptoms decreased in number and severity.
