年龄与代谢综合征的关系及防治对策

目的 了解中老年人群年龄与多种代谢异常的聚集状况,为心脑血管疾病的一级预防提供依据.方法 对744例中老年人按不同年龄分为5组,分析代谢综合征各项指标的变化规律及特点.结果 年龄与肥胖呈明显负相关(P＜0.001),与高血糖、高血压及冠心病、脑卒中呈明显正相关(P＜0.05,或P＜ 0.001);40～60岁组代谢综合征的患病率基本一致(约为30%),70岁以后明显增加,到80岁时可高达51%( P＜0.05,或P＜0.01).代谢综合征与冠心病和脑卒中的患病率均明显相关(P＜0.05),随着临床指标个数的增加,冠心病的患病率增加了6.8%,脑卒中的患病率增加了7.44%.结论 中年人群超重或肥胖的患病率明显高于老年组,应引起足够重视;随着年龄增长,代谢异常数目增多,尤其是≥3项指标的人数明显增加;代谢综合征作为心血管危险因素直接导致冠心病、脑卒中患病率增加.因此,针对中老年人群代谢综合征的特点,制定相应的干预措施十分重要.     

重症监护病房真菌耐药监测及与中医证型的关系

目的明确重症监护病房(ICU)侵袭性真菌感染的细菌病原学、耐药性及与中医证型的关系,指导临床经验性使用抗菌药物。方法对中国中医科学院广安门医院2006-03—2007-02ICU患者侵袭性感染真菌及其对抗细菌药物的耐药性进行回顾性调查。结果ICU真菌感染主要以念珠菌为主,念珠菌中以白色念珠菌为最多。真菌感染中医辨证以虚实夹杂证最常见,而又以气阴两虚、痰热互结为最多,实证以痰热内结为主。结论依据真菌病原学、抗菌药物敏感性结果及中医证型分布,有效选择中西医疗法,减少新的耐药株的出现,发挥中医优势。     

肾综合征出血热病毒气溶胶的物理稳定性实验研究

本文采用荧光素钠正常鼠脑悬液做模拟示踪物质，对肾综合征出血热病毒气溶胶在空气中的物理稳定性进行了测定，并与其生物稳定性做了比较。结果表明：病毒气溶胶的粒子大小在１ｕｍ左右，它随气溶胶的胶龄增长而减少，且其分散度变窄。初始气溶胶的物理回收率及其各胶龄的物理存留率均明显地高于它的生物回收率和生物存活率。本文还就肾综合征出血热病毒气溶胶的物理稳定性和生物稳定性，对本病空气传播的影响进行了讨论。     

Effect of linoleic acid, linoleic acid anilide, and arachidonic acid on the expression of adhesion molecules on human neutrophils

The effects of linoleic acid, linoleic acid anilide, and arachidonic acid on the expression of CD11b/CD18, CD11c/CD18 integrins and l-selectin on human neutrophils were studied by flow cytometry in a whole blood assay. None of these compounds had any effect on the basal expression of CD11b, CD11c, or l-selectin in the concentration range of 20–100 μM. However, linoleic acid at a concentration of 1000 μM slightly up-regulated CD11b and CD11c by a factor of 2.1 and 1.7, respectively. Linoleic acid, linoleic acid anilide, and arachidonic acid did not affect the formyl-methionyl-leucyl-phenylalanine induced up-regulation of CD11b or CD11c. However, linoleic acid and linoleic acid anilide slightly inhibited the phorbol myristate acetate (PMA)-induced expression of CD11b, which was decreased by 27 and 21% at concentrations of 100 and 1000 μM, respectively. Likewise, arachidonic acid at 40 μM inhibited the PMA-induced expression of CD11b by 19%. Our results suggest that linoleic acid, linoleic acid anilide, and arachidonic acid do not dramatically affect the expression of leukocyte adhesion molecules in a whole blood assay.

Clinical study of Tuina on tension-type headache with syndrome differentiation

本研究采用六点行为评分法和Stead的诊断表计分法.对治疗组和对照组150例患者进行客观、科学的疗效评定.提示"通脉调气"腹部推拿法在治疗紧张性头痛的疗效上远远高于常规推拿法.同时认为消除由"头痛-肌收缩一头痛"程序而引起过度防御反应是疗效显著提高的理论基础.     

代谢综合征患者血管内皮损伤标志物、C反应蛋白与胰岛素抵抗的关系

目的:观察代谢综合征(MS)患者血管内皮损伤标志物血管性假性血友病因子抗原(vWF:Ag)、凝血酶调节蛋白(TM)及超敏C反应蛋白(Hs-CRP)的水平变化及其与胰岛素抵抗的关系。方法:测定67例MS患者(其中合并冠心病31例)及35例健康对照组TM、vWF:Ag、Hs-CRP、空腹胰岛素(Fins)水平,计算胰岛素抵抗指数(IR)。结果:单纯MS组(B组)TM、vWF:Ag、Hs-CRP水平明显高于对照组(A组),P<0.05;MS合并冠心病组(C组)TM、vWF:Ag、Hs-CRP水平均高于A组和B组,差异有显著性统计学意义(P<0.05)。单因素直线相关分析表明TM、vWF:Ag、Hs-CRP与IR显著正相关(r分别为0.32、0.36、0.38)。结论:MS患者血管内皮损伤标志物、CRP水平升高,且与IR抵抗有关。     

Sinoatrial Node Electrogram Studies in Patients with Sick Sinus Syndrome

Sinoatrial node electrogram (SNE) was recorded successfully in recent years, using transvenous electrode catheter. Via SNE and intratrialelectrogram (IEG), one could measure sinoatrial conduction time(SACT) directly, observe sinoatrial node (SN) potential changes in cadiac cycles, diagnose some sinus arrhythmias which couldn't be confirmed by surface ECG. All these could offer accurate evidence for differential diagnosis of sick sinus syndrome (SSS). The authors recommend a modified method for the location of the electrode catheter, by which one can increase success rate of obtaining stable SNE. Using this method, the authors recorded SNE in 10 cases with SSS successfully.

An evaluation of Tourette Syndrome and medication use in Canada

Self-report data were gathered from a national sample of over 200 Canadian Tourette Syndrome (TS) patients. Information regarding symptom severity both on and off medication was gathered along with an analysis of different medications in use, and patient ratings of effectiveness of those medications. Patients also rated their own mental health. Results indicated that approximately 60% of TS patients take some form of medication for relief from their symptoms. Of these, over 80% reported that symptoms are less severe when medicated. The most commonly prescribed medications in order of popularity are haloperidol, pimozide, clonidine and benztropine mesylate (Cogentin). Patient ratings of effectiveness of these medications places haloperidol first, pimozide second and clonidine third although all were found to be "somewhat" to "very" effective. Of those TS patients on medications, 50% rated their own mental health as good to excellent and 50% rated it as fair to poor.     

基于十年随访的心血管代谢性危险因素聚集与社区≥55岁人群全因死亡风险关系的队列研究

背景 心血管代谢性危险因素聚集（CRFC）是老年人常见的健康问题,目前相关研究主要集中在流行病学分布特征的描述,有关CRFC与人群全因死亡风险的研究鲜有报道。目的 探讨CRFC与社区≥55岁人群全因死亡风险的关系,为开展≥55岁人群社区保健提供参考。方法 于2011年9—11月采用典型抽样法选取宁夏回族自治区吴忠市和银川市5个社区的1 046名≥55岁人群作为研究对象,对其开展一般情况问卷调查、体格检查、超声检查、实验室检查和CRFC评价[纳入中心性肥胖、高胆固醇血症、高三酰甘油血症、高低密度脂蛋白血症、低高密度脂蛋白血症、高血压、糖尿病、高尿酸血症、非酒精性脂肪性肝病（NAFLD）共计9项心血管代谢性危险因素后,控制一般情况变量,通过构建多因素Cox比例风险回归模型,估计各个心血管代谢性危险因素的回归系数β,以回归系数β为权重将所有心血管代谢性危险因素的评分相加得出心血管代谢危险因素危险总评分],将心血管代谢危险因素危险总评分按照四分位数分为三组：P75组;分别于2017年,2019年和2021年通过面访和死因监测系统搜索的方式完成随访。采...
