Efficacy and safety of herbal medicines for idiopathic Parkinson's disease: a systematic review.

The objective of this study is to assess the efficacy and safety of herbal medicines (HMs), as a monotherapy or adjunct therapy, compared to placebo or conventional approaches in the treatment of idiopathic Parkinson's disease (PD). We conducted a systematic review of randomized controlled trials from both conventional and alternative medicine sources. Outcome measures were overall improvement, quality of life, reduction of levodopa dose, and adverse events. Nine studies were included, each testing a different HM. Six of the trials had limited internal validity due to major flaws in design, including the lack of proper randomization; insufficient blinding; unclear inclusive criteria in terms of diagnostic criteria, baseline staging, and duration of disease; lack of proper sample size calculation; and insufficient data analysis. Imbalances in gender and ethnicity among the patients in the included trials were observed. No major adverse events emerged, and no specific pattern was detected from the trials describing such data. In addition to major methodological defects, heterogeneity in (1) HM tested, (2) control treatment, and (3) outcome measure hindered in-depth data analysis and synthesis. Current evidence is insufficient to evaluate the efficacy and safety of various HMs. Further studies with improved trial design and reporting, with assessment on cost-effectiveness, quality of life, and qualitative data are warranted.     

护理本科生创造性思维培训

[目的]对护理本科生实施创造性思维训练,并评估该训练方案的有效性。[方法]对20名护理本科生实施为期3个月的创造性思维培训,并与24名不接受培训者进行对照。采用《创造性思维练习》量表对培训前后学生的创造性思维进行测定。[结果]培训后实验组较对照组的创造性思维总分及流畅性得分有显著提高(P<0.05);变通性和独创性得分无统计学意义(P>0.05)。[结论]创造性思维培训对提高护理本科生创造性思维总体有效,其中对提高创造性思维的流畅性效果显著。     

急性冠脉综合征脑钠肽及N-末端脑钠素原水平变化及意义

心脏具有重要的内分泌功能,它能感受心房和心室的压力,通过分泌多种利钠肽作用于肾脏、血管、心肌,并调节其他内分泌功能,在左室功能不全(LVD)的早期可减慢疾病的进展。近年来研究表明,氧化低密度脂蛋白自身抗体(OLAB)、脑钠肽(BNP)、高敏C-反应蛋白(CRP)在急性心肌梗死(AMI)、不稳定型心绞痛(UAP)的发病过程中可能是导致局部炎症反应和血栓形成的重要因素[1]。关于BNP检测在充血性心衰的早期诊断、不明原因呼吸困难的鉴别诊断、心衰的预后判断和治疗监测中的意义已有大量报道,许多临床试验证明了BNP也能为急性冠脉综合征(ACS)…     

大鼠静脉窦高压致硬膜血管变化的研究

目的探讨大鼠静脉窦高压后硬膜血管变化及其静脉窦高压在硬脑膜动静脉瘘形成中的作用。方法体重200～250g的SD雄性大鼠110只,随机分为静脉窦高压组(85只)和假手术组(25只),将静脉窦高压组85只大鼠闭塞左侧横窦和上矢状窦前1／3,并吻合右侧颈总动脉和颈外静脉,制成静脉窦高压模型。假手术组大鼠单纯解剖相应的颈部血管和硬脑膜窦,但不行吻合或闭塞。术后90d,随机取7只静脉窦高压组大鼠和5只假手术组大鼠,行硬脑膜血管明胶墨汁灌注,观察硬膜血管的状况。结果术后90d静脉窦高压组和假手术组大鼠的硬膜血管数分别为(10.7±1.5)条／mm,(10.3±0.6)条／mm,差异无显著性。在静脉窦高压组中1只大鼠有硬脑膜动静脉瘘,其形态和结构与生理性动静脉短路类似。结论大鼠静脉窦高压一段时间后,颅内硬膜血管无明显增生。颅内硬脑膜动静脉瘘的形成很可能是由动静脉间的短路发展而来。

张继泽主任医师逆转萎缩性胃炎经验举隅

慢性萎缩性胃炎是以胃黏膜上皮和腺体萎缩、黏膜变薄为特征的慢性疾病。属中医胃脘痛、胃痞等范畴。其病因病机较为复杂,多与饮食不调、情志不畅有关,尤其是饮酒、过食刺激之品,致使脾胃受损,阳气郁遏不振,纳运失司,化源不足,气血阴液亏乏;或中焦运化无力,湿邪滞塞,郁而化热;或     

Reproducibility of ultrasound pachymetry using the Sonogage Corneo-Gage Plus 2.

PURPOSE: The aim of this study was to determine the reproducibility of measurements made using the Sonogage Corneo-Gage Plus 2 (Cleveland, Ohio) ultrasound pachymeter of total corneal and corneal epithelial thickness in 5 different regions of the cornea. METHODS: Twenty-seven subjects at the New England College of Optometry (NECO) and 20 subjects at the Southern College of Optometry (SCO) were enrolled in this study. Measurements were taken of the central cornea as well as the nasal and temporal regions of the midperipheral and peripheral regions of the right cornea of each subject. Identical measurements were again taken in these subjects 1 week later at approximately the same time of day. Within-subject variations were then assessed using paired t tests. RESULTS: The only significant measurement differences that were found between visits were for full corneal thickness at both the nasal and temporal midperipheral locations. The mean differences for these locations were 13.5 microm and 13.7 microm, respectively. CONCLUSIONS: Epithelial corneal thickness and central and peripheral total corneal thickness measurements using the Corneo-Gage Plus 2 pachymeter were reproducible; however, midperipheral total corneal thickness measurements showed poor reproducibility.     

180篇创伤骨科论文临床疗效研究方法的评估
