老年非瓣膜性房颤脑卒中危险分层及抗凝现状分析

目的　对非瓣膜性房颤 (NVAF)脑卒中危险分层及基层医院抗凝现状分析。方法　选择NVAF住院患者 1 2 0例并分成ABC三组 ,分别统计脑卒中发生率 (五年 )。将治疗分a组 (未抗凝 ) ,b、c组 (阿司匹林抗血小板聚集 ) ,d组 (华法林抗凝 )。结果　 1 2 0例中A组脑卒中人数 1 3人 (59.1 % )。B组脑卒中人数 2 2人 (2 9.3 % )。C组 1人 (4.3 % )。A组与B组 ,B组与C组比较有明显差异 (P <0 .0 5)。d组脑卒中发生率为 0 ,明显优于a组。阿斯匹林≥ 1 50mg d(c组 ) ,脑卒中发生人数 3人 (1 2 .5 % ) ,与a组比有明显差异 (P <0 .0 5)。结论　A、B组脑卒中发生率明显高于C组 ,口服华法令及阿斯匹林可降低脑卒中发生率。基层医院对NVAF患者抗凝治疗不充分 ,脑卒中发生率高。     

阿司匹林间歇疗法在脑卒中二级预防中的临床价值

目的观察阿司匹林间歇疗法与常规疗法在脑卒中二级预防中临床价值的差异。方法收集250例脑卒中恢复期患者,按随机单盲开放对照原则分为间歇疗法组(间歇组)(每8周内停药1周)和常规疗法组(单规组)各125例,均给予阿司匹林100mg Qd治疗2年。结果(1)2组脑卒中再发率无明显差异;(2)2组患者的血小板聚集率和凝血功能无明显差异;(3)间歇组上消化道出血、腹痛、腹泻等不良反应发生率较常规组明显下降(P<0.01)。结论阿司匹林间歇疗法较常规疗法能有效减低了长期治疗导致的消化道不良反应,同时有效降低脑卒中的再发率,在脑卒中二级预防中具有重要的临床应用价值。     

女性服刑人员精神创伤的特征

目的调查女性服刑人员精神创伤的特征。方法在湖南新路职业学校中,采用多级随机整群抽样的原则抽取471个女性服刑人员,分青少年组（年龄≤25岁）和成年组（〉25岁）。运用创伤性生活事件问卷（TLEQ）和访谈相结合的技术评估她们的精神创伤经历。结果（1）90.4%的女性服刑人员至少经历1件创伤性事件,63.7%至少经历3件或以上的多重创伤。青少年组的事件数量多于成年组（平均为4和3件,P〈0.01）。暴力和毒品相关犯罪组的事件数量相当（平均4件）,都多于经济犯罪组（2件）;中学或相当教育程度者的事件数量最多（4件）,大专或以上者最少（2件）;未婚、离婚/丧偶2组经历的事件数量最多（4件）,已婚组最少（2件）,均差异有显著性（P〈0.05）。（2）最多见的创伤类型是机动车祸（46.9%）、目睹家庭暴力（46.1%）和被抢劫（38.9%）。16.7%的女犯在18岁以前遭遇过性虐待。与成年组相比,青少年组经历了更多的创伤类型为被抢劫、目睹被惨打、目睹家庭暴力,以及儿童期性虐待。结论我国文化背景下,女性服刑人员的精神创伤经历相当普遍,是精神创伤的潜在受害者。     

刺激颈迷走神经引起的心动过速及其对心脏功能的影响

刺激犬的颈迷走神经外周端时可引起心动过缓,而对心脏的抑制作用则逐渐减弱,表现为心率逐渐恢复(但比对照慢)。刺激后DBP立即下降,而SBP系逐渐下降,且下降程度没有DBP大。在刺激时及停止后均出现ES,其分别占刺激次数的47％和53％。在刺激停止后出现PVT(平均加速24.5次/min),PVT期间R波和BP波数不等,SV和BP轻度降低。LVET缩短和PEP/LVET比值升高,出现ES时,SV和BP较ES前显著降低。反映PVT时心脏功能降低。PVT的要理不太清楚,本研究表明反射性迷走撤退在PVT中不起作用。Q-T/Q-S_2比值增大是CA释放的间接证据。心得安可减弱PVT,阿托品可增强PVT,说明PVT由迷走静经释放CA所致。     

基层医院组建卒中小组的初步探讨

目的总结探索在基层医院组建卒中小组，治疗急性脑卒中的模式。方法组建包括社区网络在内的院内卒中小组，对脑卒中患者进行动态的全面评估和系统的个体化治疗。结果规范了急性脑卒中的临床治疗行为，改善了患者预后。结论在基层医院建立卒中小组是一种可行的治疗模式。     

多糖硫酸脂(PSS)治疗缺血性脑血管病临床观察和实验室研究

应用PSS治疗270例缺血性脑血管病并进行了临床、实验室以及动物试验的观察.总有效率为92.27%;显效率65.24%,与对照组相比较有显著性差异(P<0.005).实验室观察发现PSS有显著的抗凝血、降低血粘度,降低血脂及血管扩张作用.动物实验也说明了这一点.     

Changes in cardiovascular function induced by verapamil in healthy subjects and in patients with ischemic heart disease

Alterations in cardiovascular function induced by the acute intravenous administration of verapamil (5 or 10 mg) in 52 patients (29 with ischemic heart disease and 23 without heart disease) were evaluated with use of invasive techniques (right and left heart catheterization, left ventricular cineangiography, and coronary arteriography). The most significant changes were represented by a decrease in systemic vascular resistance and systemic arterial pressure, and an increase in heart rate and cardiac output. Contractility indexes were not depressed in either group, and altered ventricular wall motion tended to improve to a slightly smaller degree than in patients treated with nitroglycerin. The use of verapamil in patients with ischemic heart disease appears to be safe, and concern about the negative inotropic influences in humans no longer seems justified.     

Impact of Retrograde Cerebral Perfusion on Ascending Aortic and Arch Aneurysm Repair

Purpose. The effect of retrograde cerebral perfusion on the incidence of stroke and death among patients undergoing repair of aneurysms of the ascending aorta and transverse arch was determined.

Material and Methods. Between January 1991 and March 1995, 161 patients were operated on for aneurysms of the ascending aorta and transverse arch. Thirty-three of the patients (20%) had an aneurysm of the ascending aorta only and 128 (80%) had aneurysms of both the ascending aorta and the transverse arch. All the patients underwent cardiopulmonary bypass, profound hypothermia, and circulatory arrest, and 120 (74%) also underwent retrograde cerebral perfusion. Median pump time was 143 minutes (range, 21 to 461 minutes). Median circulatory arrest time was 42 minutes (range, 8 to 111 minutes), and median myocardial ischemic time was 71 minutes (range, 14 to 306 minutes).

Results. The overall 30-day mortality rate was 6% (9 patients) and the incidence of stroke was 4% (7 patients). The use of retrograde cerebral perfusion demonstrated a protective effect against stroke (3 of 120 patients, or 3%) compared with no retrograde cerebral perfusion (4 of 41 patients, or 9%; odds ratio, 0.24; confidence interval, 0.06 to 0.99; p < 0.049). This was most significant in patients more than 70 years of age; none of the 36 elderly patients who received retrograde cerebral perfusion had a stroke, compared with 3 of the 13 (23%) who did not (p < 0.003). Only pump time was associated with an increased risk of stroke (odds ratio, 1.01; 95% confidence interval, 1.00 to 1.02; p < 0.005). Pump time also was associated with increased mortality (odds ratio, 1.01; 95% confidence interval, 1.00 to 1.02; p < 0.008).

Conclusion. Retrograde cerebral perfusion decreased the incidence of stroke in patients undergoing repair of aneurysms of the ascending aorta and transverse arch.
