Sequential Therapy Based on Evolvement of Patterns: A New Model for Treatment of Alzheimer’s Disease

In order to solve the problem of long-term (>9 months) efficacy in the treatment of Alzheimer''s disease (AD) by conventional therapy (CT), a staged and multiply-targeted sequential therapy based on the evolvement of patterns (STEP) was developed. Its main innovations include: (1) the time order of evolution of patterns defined by Chinese medicine (CM) in AD was found, that is, "the orderly pattern evolution starting from Shen (Kidney) deficiency, progressing to phlegm, stasis and fire, and worsening to severe toxin as well as functional collapse"; (2) the cascade hypothesis of Shen deficiency in AD and its sequential therapy based on Shen-reinforcing was proposed, that is, "reinforcing Shen in the early stage and throughout the whole process, resolving phlegm, activating blood and purging fire in the middle stage, detoxifying and replenishing vitality to stop the collapse in the advanced stage", and through meta-analysis, clinical drug use was optimized, thus the leap from "inferential selection" to "evidence-based selection" was realized; (3) the STEP regimen combined with CT maintained cognitive and behavioral stability in AD patients for at least 12 months, with cognitive enhancement and behavioral synergy after 9 months, and cognitive benefit was superior to CT at 9, 12, 15, 18, 21, and 24 months, respectively. The 2-year cognitive improvement rate was increased by 25.64% (P=0.020) and the cognitive deterioration rate was decreased by 48.71% (P=0.000). Among them, the cognitive and functional benefits of Shen-reinforcing therapy for very early AD (350 cases) for 1 year were better than the placebo (P<0.001), and the dementia conversion rate was reduced by 8.85% (P=0.002). The behavioral symptomatic relief of patients with vascular dementia received fire-purging therapy (540 cases) was superior to those received CT (P=0.016). These data suggested that the STEP regimen has synergistic effects on CTs at least in terms of cognitive benefit, and the earlier the use, the greater the benefit will have. Therefore, the STEP regimen should be considered as one of the clinical options, particularly for the dearth of effective pharmaceutical or immunological interventions that are currently available for AD.     

白芷酒炖前后挥发性成分的HS-SPME-GC-MS分析

目的探讨白芷酒炖前后对挥发性成分的影响。方法采用顶空固相微萃取技术(HS-SPME)结合气相色谱-质谱法(GC-MS)对白芷酒炖前后挥发性成分及其相对百分含量进行对比分析。结果从白芷生品中初步检测出53个峰,鉴定出36个成分;从白芷酒炖中检测出32个峰,鉴定出26个成分;与生品成分比较,酒炖白芷中有22种成分未测到,但新增了12种成分,表明酒炖白芷中的挥发性成分的组成和含量均发生了变化。结论白芷酒炖后由于受热及辅料黄酒的作用使挥发性成分的种类及含量发生了明显变化,并存在成分转化,本研究为白芷酒炖的炮制机理及其在都梁丸中应用的物质基础研究提供了科学依据。

员工援助计划服务对心内科护士职业认同感、职业价值观、职业压力的影响

目的 探讨员工援助计划服务对心内科护士职业认同感、职业价值观、职业压力的影响。 方法 选择2018年1-3月我院心内科护理人员58名,为其实施员工援助计划服务,评价实施前后心内科护士的职业认同感、职业价值观、职业压力感知、职业压力反应。 结果 实施后,心内科护士工作压力源各维度评分、压力感知与压力反应各维度得分均较实施前下降(P＜0.05);职业价值观各维度及职业认同感各维度评分均较实施前显著提高(P＜0.001)。 结论 员工援助计划可提高心内科护士职业认同感、职业价值观,缓解其职业压力感知以及职业压力反应。
