自适应反馈电针系统工作时,患者反馈的肌电信号(EMG)具有悬浮地平面、幅值微弱和信噪比低等缺点,造成信号采集及特征提取困难。为准确提取患者生理特征和耐针特性,本文对EMG信号产生的机理进行了研究,并建立数学模型,分析EMG信号特征。... 自适应反馈电针系统工作时,患者反馈的肌电信号(EMG)具有悬浮地平面、幅值微弱和信噪比低等缺点,造成信号采集及特征提取困难。为准确提取患者生理特征和耐针特性,本文对EMG信号产生的机理进行了研究,并建立数学模型,分析EMG信号特征。本研究设计了高精度EMG信号采集电路,采用小波变换提取EMG特征,能够为电针系统提供准确的反馈信息,保证闭环系统工作的实时准确性。 展开更多

Objective:To evaluate the clinical efficacy of acupuncture in the treatment of anxiety state in patients with primary insomnia(PI).Methods:Randomized controlled trials of acupuncture treatment for PI patients with an anxiety state in Web of Science,Cochrane Library,PubMed,Excerpta Medica Database(EMBASE),China National Knowledge Infrastructure(CNKI),Wanfang Data Knowledge Service Platform(Wanfang),and Chongqing VIP Database(VIP)were retrieved by computer.The retrieval time was from each database’s inception to December 30,2022.Data extraction and evaluation were performed for the included studies.The Cochrane risk of bias assessment tool was used to assess the risk of bias in each article.Meta-analysis of valid data was performed using the RevMan 5.4 software.If the outcome indicator was a categorical variable,relative risk(RR)was used as the effect size.If it was a continuous variable,mean difference(MD)was used to calculate the effect size.Each effect size was expressed as a 95%confidence interval(CI).P<0.05 was considered to indicate a statistically significant difference.Results:A total of 18 studies were included,comprising a total of 1198 patients.The findings of the meta-analysis showed that electroacupuncture had a significant advantage in improving the Hamilton anxiety scale(HAMA)score than benzodiazepines[MD=-1.61,95%CI(-2.17,-1.06),P<0.001].Acupuncture was superior to sham acupuncture[MD=-14.90,95%CI(-20.39,-9.41),P<0.001]and benzodiazepines[MD=-3.39,95%CI(-4.67,-2.12),P<0.001]in reducing the self-rating anxiety scale(SAS)score.Acupuncture was superior to sham acupuncture in reducing the insomnia severity index(ISI)score[MD=-5.61,95%CI(-6.63,-4.89),P<0.001].Acupuncture was superior to benzodiazepines[MD=0.84,95%CI(-1.42,-0.25),P=0.005]and sham acupuncture[MD=-8.39,95%CI(-8.39,-7.86),P<0.001]in improving the Pittsburgh sleep quality index(PSQI)score.Acupuncture had a better effective rate than benzodiazepines[RR=1.16,95%CI(1.08,1.25),P<0.001]and sham acupuncture[RR=8.94,95%CI(4.63,17.25),P<0.001]in treating PI.Conclusion:Acupuncture or electroacupuncture has certain therapeutic advantages over benzodiazepines and sham acupuncture in the treatment of anxiety in PI patients.However,more high-quality randomized controlled trials are needed for further verification. 展开更多

目的:观察电针对急性手术创伤大鼠术后苏醒质量和下丘脑、海马促肾上腺皮质激素释放因子(CRF)表达的影响,探讨大鼠下丘脑与海马CRF表达的相关性在针刺调节急性手术创伤所导致的下丘脑-垂体-肾上腺(HPA)轴功能异常中的作用。方法:雄性SD... 目的:观察电针对急性手术创伤大鼠术后苏醒质量和下丘脑、海马促肾上腺皮质激素释放因子(CRF)表达的影响,探讨大鼠下丘脑与海马CRF表达的相关性在针刺调节急性手术创伤所导致的下丘脑-垂体-肾上腺(HPA)轴功能异常中的作用。方法:雄性SD大鼠20只,随机分为正常组、模型组、假电针组和电针组。肝叶切除术建立急性创伤模型。电针组电针右侧"足三里"和"三阴交",假电针组仅针刺"足三里"和"三阴交",不接电针,于造模前24h及造模后各治疗1次。观察各组大鼠麻醉苏醒时间及翻正反射情况。应用Western blot方法检测各组动物下丘脑和海马CRF的表达。结果:电针组大鼠麻醉苏醒时间显著缩短,翻正反射迅速恢复,和模型组、假电针组相比差异有统计学意义(P<0.001,P<0.01)。苏醒时间与翻正反射有相关性(r=0.646,P<0.05)。模型组大鼠下丘脑CRF表达升高,和正常组相比差异有统计学意义(P<0.05),电针组大鼠下丘脑CRF表达降低,和模型组、假电针组相比差异有统计学意义(P<0.05)。模型组大鼠海马CRF表达降低,和正常组相比差异有统计学意义(P<0.05),电针组大鼠海马CRF表达升高,和假电针组、模型组相比差异有统计学意义(P<0.05)。术后大鼠下丘脑CRF表达与海马CRF表达呈负相关(P<0.001),与翻正反射呈正相关(P<0.01),即Y下丘脑=0.452-0.546X海马+0.200X翻正反射。海马CRF表达与刺激方式呈负相关(P<0.001),与电针干预呈正相关(P<0.01),该表达式为Y海马=0.773-0.129X刺激方式+0.120X电针。结论:电针可缩短手术大鼠术后苏醒时间。下丘脑和海马CRF的表达与大鼠术后苏醒时间及干预方法均呈一定相关性,提示下丘脑和海马CRF在调节机体应激反应中可能起关键作用。电针可能通过激活海马CRF神经元,抑制下丘脑CRF神经元,进而调整急性手术创伤所致的大鼠HPA轴功能异常,减轻术后应激。 展开更多
