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。     

匹格列酮激活过氧化物酶体增生物激活受体(PPAR-γ)提高伴有主要心血管危险因素的非糖尿病病人内皮依赖舒张功能

研究背景:伴有心血管危险因素的患者有内皮功能障碍,是导致动脉粥样硬化发病机制的关键因素之一, 在糖尿病患者中应用四氢噻唑产生了多种抗动脉粥样硬化的作用,本研究证实匹格列酮在伴有心血管危险因素的非糖尿病病人中提高内皮功能的假设。方法和结果:研究采用随机,双盲,安慰剂对照,交叉设计。入选80 名同时伴有高血压和高胆固醇血症的患者。胰岛素敏感性用定量胰岛素敏感检测指数(QUICK)评价。进一步将患者分为胰岛素敏感和胰岛素抵抗,在每个治疗阶段,患者每天服用匹格列酮45 mg或安慰剂共八周,在每8 周末,进行实验室检查。应用匹格列酮组血浆胰岛素水平显著下降,QUICK胰岛素敏感指数升高,HDL升高,甘油三酯、自由脂肪酸,和C-反应蛋白水平降低。匹格列酮治疗显著提高缓激肽的内皮依赖性舒张功能而不影响对硝普钠的反应。多变量分析显示:只有总胆固醇的变化预示匹格列酮提高内皮活性。结论:伴有心血管危险因素的非糖尿病病人中,匹格列酮治疗提高胰岛素敏感性,降低C-反应蛋白,提高内皮血管扩张功能。这些结果并不密切相关,提示匹格列酮对血管的有益作用独立于其对胰岛素敏感性和炎性的作用。     

2 121例老年急性冠脉综合征患者血清脂类浓度的分析

目的分析60岁以上老年人血清脂类水平的参考值,并探讨急性冠脉综合征与血脂指标的相关性.方法将3 766例健康成人分为≤60岁和＞60岁的两个年龄段,采用生物化学的方法测量他们的血脂水平,找出60岁以上老年人的脂类参考值.同时分析2 121例老年急性冠脉综合征病人的脂类指标.结果 60岁以上老年人血脂参考值为:TC 4.65±1.96×1.05mmol/L;TG 1.02±1.96×0.45mmol/L;HDL-C 1.47±1.96×0.40mmol/L;LDL-C 2.98±1.96×0.56mmol/L;ApoA1 1.32±1.96×0.25g/L;ApoB 0.99±1.96×0.35g/L,并且急性心肌梗死和不稳定性心绞痛病人血清脂类各项指标之间没有显著性差异.结论血清LDL-C/HDL-C＞5和TG ≥1.9mmol/L这两项联合指标比其他单独指标与老年人急性冠脉综合征关系更密切.     

Non-invasive Assessment of Coronary Flow Velocity Reserve: A New Method Using Transthoracic Doppler Echocardiography

Coronary flow reserve (CFR) has been used toassess coronary microcirculation and epicardial coro-nary stenoses[1— 3 ] . CFR is defined as the ratio ofcoronary flow under maximal coronary vasodilatationto coronary flow under resting conditions[4 ] .Whenthe cross- sectional area of epicardial coronary arteriesis constant,coronary flow velocity (CFV) ratios areequal to volume flow ratios.The most common method used clinically formeasuring CFVR is intracoronary Doppler flow(ICD) analysis re…     

胸膜腔造影和注射粘连剂对难治性气胸的诊治

目的：为更清晰地显示顽固性气胸的漏气部位和性质，为不能耐受手术者摸索一种新的治疗手段。方法：选择１８例患者，先用７６％泛影葡胺行胸膜腔造影，而后在局部注入少量粘连剂。结果：造影后发现多发性肺大泡８例，单发性肺大泡６例，肺大泡伴粘连带４例。病变分别位于左上肺，右上肺，中下肺野及叶间裂。注射粘连剂后，１５例一次成功，３例第二次成功。随防６～１８个月，未见复发。结论：该方法易掌握，无明显副作用。病变显示明显，易被患者接受，具有明显的临床效果和推广价值
