目的:探讨电针对急性心肌缺血家兔大脑皮层感觉门控的影响,以及不同经穴作用的相对特异性。方法:随机选择10只家兔作为正常组,余家兔冠状动脉结扎法复制急性心肌缺血模型。将模型复制成功的家兔随机分为模型组、神门组、太渊组,每组10只。各电针组分别电针"神门""太渊"穴,刺激电流为1mA,频率为2Hz,刺激15min。采用BIOPAC生物信号采集系统观察各组家兔心率,利用美国NEUROSCAN ERPs工作站,记录各组家兔大脑皮层听感觉门控电位P 50变化情况。结果:与正常组比较,模型组心率下降(P0.01),S 2-P 50波幅增大(P0.01),S 2/S 1增大(P0.01),S 1-S 2以及100×(1-S 2/S 1)减小(均P0.01);与模型组比较,神门组家兔心率加快,S 2-P 50波幅减小(均P0.01),S 2/S 1减小(P0.01),S 1-S 2以及100×(1-S 2/S 1)增大(均P0.01)。太渊组以上各指标均无明显改善,与神门组的差异均具有统计学意义(P0.01)。结论:电针不同经穴对急性心肌缺血家兔大脑皮层感觉门控能力的调整作用具有相对特异性,电针心经原穴"神门"的调整作用优于电针肺经原穴"太渊"。  相似文献

目的研究太原市室内外空气颗粒物污染特征。方法于2004年4月-2006年10月在太原市21个社区541户家庭采用Aerocet531型粉尘仪-粒子计数器在采暖期和非采暖期测定室内外空气中PM1.0、PM2.5、PM7.0、PM10.0和TSP的浓度。应用Stata 9.0统计软件进行统计学分析。结果太原市空气污染最严重的社区室内、外TSP浓度分别为1 030.70和1 681.46μg/m3,采暖期与非采暖期比较,采暖期颗粒物浓度高于非采暖期;室外颗粒物浓度高于室内。对室内、外TSP贡献最大的是粒径2.5~7.0μm的颗粒物(PM>2.5~7.0),相应的构成比分别为37.58%和34.70%,其中室内污染以PM≤7.0(粒径≤7.0μm的颗粒物)为主,室外污染以PM>2.5(粒径>2.5μm的颗粒物)为主。不同粒径颗粒物相关性分析结果表明,TSP与PM>2.5~7.0相关性最强,相关系数为0.928 0。室内、外采暖期PM>2.5~7.0相关性最强,采暖期相关系数高达0.675 3。结论太原市主要颗粒物污染为PM>2.5~7.0,室外空气颗粒物污染对室内影响较大,采暖期室内、外PM>2.5~7.0高度相关。  相似文献

目的:了解太原市阿片类物质依赖者稽延性戒断综合症的耳穴电阻,为下一步中医证候学研究提供一些基础性参考资料。方法:对2004年5月17日之前进入太原地区某强制戒毒所100例戒毒病人进行访谈,以自制量表记录情况,进行横断面研究。观测手背皮肤、神门、交感、皮质下、内分泌电阻值,并进行组间比较。结果:接受调查的99例患者数据显示,5组采集数据皮肤电阻有统计学意义。经过S-N-K法检验,神门(19.39)、交感(20.11)的皮肤电阻值最小;皮质下略高(23.20);内分泌(25.24)和手背皮肤(25.12)电阻最高。结论:阿片类稽延性戒断综合征患者的神门、交感及皮质下处于低电阻的状态,而内分泌和手背皮肤电阻值无特殊变化,临床治疗中,刺激神门、交感及皮质下可能有助于治疗阿片类稽延性戒断综合征,且刺激神门、交感的效果可能会优于刺激皮质下。  相似文献

太渊穴自发红外辐射与肺功能的相关性分析   总被引:4,自引:0,他引:4  
目的探讨太渊穴自发红外辐射与肺功能的相关性。方法用PHE201型体表红外光谱仪对104名志愿者的太渊、大陵及非穴位对照点的自发红外辐射进行检测,分析其与肺功能的相关性。结果在穴位和非穴位对照点共6个检测部位中,有4个检测部位在某些波长的自发红外辐射强度与第1秒呼气容积(FEV1)和最大通气量(MVV)有相关关系(r=0.197~0.334,P<0.05或P<0.01),其中左太渊穴自发红外辐射与肺功能有相关关系的波长数明显多于其他检测部位(P<0.01)。结论太渊穴自发红外辐射与肺通气功能有明显的相关性,能灵敏地反映肺通气功能的变化。  相似文献

The treatment of renal cell carcinoma has achieved certain curative effects with the innovation of clinical drugs, such as sunitinib. However, the clinical efficacy and complication rate of the sunitinib 2/1 and 4/2 schedule in metastatic renal cell cancer remain unclear. In this study we aimed to resolve this issue by using meta-analysis to provide more theoretical guidance for clinical use. Several outcome measurements were included in this study to compare the 2 schedules such as complete response, partial response, stable disease, progressive disease, progression-free survival, overall survival, and complications. In the contrast analysis, the sunitinib 2/1 and 4/2 schedule resulted in significant improvements in prognosis. However, the sunitinib 2/1 schedule was superior to the 4/2 schedule in terms of controlling stable disease and causing fewer complications.  相似文献

背景 近年来,太原市家庭医生签约工作正逐步开展,但在就医过程中“看病难、看病贵”问题凸显。为规范医疗秩序,合理就医,了解家庭医生签约政策现状具有重要意义。目的 了解太原市家庭医生签约政策在制定和运行过程中存在的问题,并为其更好地发展提供对策和建议。方法 采用方便抽样方法,在太原市3个城区(迎泽区、小店区、晋源区)的社区卫生服务站各选择1个家庭医生团队(共17例访谈对象);另选择太原市卫生健康委基层处4例工作人员为研究对象。采用深度访谈方法,于2019年4-6月对21例研究对象进行访谈。访谈的主要内容包括:太原市家庭医生签约政策文件的进展,家庭医生签约政策制定过程中的指标、合同条目和目标,签约服务过程中存在的问题。最后对访谈资料进行整理归纳,总结主题。结果 通过对访谈资料进行分析,共提炼出6个主题:签约率虚高与服务利用率低之间的矛盾;签约率虚高与合同信息不透明之间的矛盾;新旧政策衔接差,政策权威性不足;出现“签而不约”问题;诊疗秩序不规范;家庭医生数量不足。结论 建议通过建立有效签约机制、规范服务合同内容、合理配置新旧政策、规范分级诊疗秩序和大力培养优质人才的方式解决家庭医生签约过程中存在的问题与矛盾。  相似文献

目的评价骨折风险预测简易工具(FRAX)在太原市部分中老年人骨质疏松性髋部骨折风险评估中的应用价值。方法在山西医科大学第一医院治疗的髋部骨质疏松性骨折患者(n=292)为骨折组,以骨折组为标准,按性别、年龄配对,招募相同地域的社区居民为对照组(n=292)。2组均使用双能X线骨密度仪(DXA)检测股骨颈骨密度(BMD),收集骨折危险因素,采用FRAX中国模式分别预测2组受试者在有无BMD条件下10年发生髋部骨质疏松性骨折的概率。结果骨折组在有无BMD的条件下10年发生髋部骨质疏松性骨折的概率均高于对照组(P0.01)。有BMD时FRAX预测髋部骨质疏松性骨折的ROC曲线下面积高于无BMD时(0.905、0.701,P0.01),但有无BMD的FRAX预测ROC曲线下面积均低于BMD测定。结论采用FRAX预测太原市部分中老年人骨质疏松性髋部骨折风险评估有一定价值,但预测骨折风险值较低,需要进一步矫正。  相似文献

Background

We previously constructed a Self-Mutual-Group health management model, focusing on improving individuals' awareness of health management and ability in self-management, mutual-management, and group-management by increasing their self-efficacy. We aimed to evaluate the effectiveness of the Self-Mutual-Group model on social support among the empty-nest elderly (ie, those who live on their own), and to explore the related factors that might have a role in the intervention effect, thus providing information for improving the social support of empty-nest elderly.

Methods

We did an open-label, randomised controlled trial of six communities in Taiyuan, Shanxi province, China. We included empty-nest elderly individuals aged 60–88 years if they had no cognitive disorder or other mental illnesses, were willing and able to complete the investigation, and were dwelling in the community for at least 1 year before the study. We randomly assigned participants using a computer system to either the intervention group with a 7-month intervention or the control group with no intervention. The 7-month intervention consisted of three stages (self-management at months 1–2, mutual management at months 3–4, and group management at months 5–7) and was held at local health-care or residential activity centres by researchers and community workers assisting in the Self-Mutual-Group-based interventions. We assessed the social support of the participating elderly using the Social Support Rating Scale (SSRS) at baseline and 7 months' follow-up. This study was approved by the institutional review boards of Shanxi Medical University. We obtained informed consent from all participants. This trial is registered with the Chinese Clinical Trial Register, number ChiCTR1800015884

Findings

Between Aug 1, 2016, and Sept 30, 2016, we enrolled 350 empty-nest elderly individuals; 167 in the intervention group and 183 in the control group. At 7 months' follow-up, we observed a significant increase between the intervention group and the control group in the mean scores of SSRS, objective support, and subjective support. The main influencing factors of the intervention effect were sex, marriage status, income sources, monthly income and employment status, relationship with children, and self-care ability of daily living.

Interpretation

The Self-Mutual-Group model was considered a positive intervention and was effective in increasing social support among the empty-nest elderly. Among the empty-nest elderly, men without spouses have a lower socioeconomic status than those with spouses. Therefore, those who do not have the ability for self-care should be the focus of future research and model popularisation to increase their social support effectiveness and improve their quality of life. Furthermore, future research might extend the intervention period and introduce multi-point measurement to better evaluate the intervention process and outcomes.
