目的:探讨氟西汀联合心理干预治疗心血管疾病患者伴焦虑抑郁症状的临床疗效。方法:选择伴有抑郁、焦虑情绪障碍的85例冠心病患者(心功能Ⅱ、Ⅲ级),并将其随机分成研究组和对照组。观察6w,对照组患者仅给予常规的治疗,研究组患者在常规治疗基础上给予氟西汀联合心理干预治疗。观察治疗前后两组患者采用汉密顿焦虑量表( Hamilton Anxiety Scale,HAMA) 评定焦虑症状,汉密顿抑郁量表( Hamilton Depression Scale,HAMD) 评定抑郁症状;并对治疗后心功能分级(NYHA)恢复到Ⅰ级的例数及左室射血分数进行分析评价。结果:治疗6 周 后,研究组均较对照组的汉密顿焦虑量表及汉密顿抑郁量表评分下降显著( P lt;0.01),研究组抗焦虑显效率为87.16%、抗抑郁显效率为82.26%,对照组分别为43.75%、45.36%,研究组均显著高于对照组( P lt;0.01);研究组患者的左室射血分数显著高于对照组 ( P lt;0.05),心功能分级(NYHA)恢复到Ⅰ级的例数显著高于对照组 ( P lt;0.05)。结论:氟西汀联合心理干预治疗不仅能改善心血管疾病伴焦虑抑郁患者的焦虑、抑郁情绪障碍,还能改善患者的心功能,疗效显著优于单用心血管药物治疗。
目的 阻塞性睡眠呼吸暂停低通气综合征（OSAHS）可引起心血管疾病发生增高，是高血压病及冠心病等的独立危险因素。打鼾是OSAHs的主要临床症状。本研究的主要目的是了解成都地区自然人群打鼾发生情况及其与心血管疾病危险因素的关系。 方法 2007年在成都市成华区采用随机抽样方法对男、女性共711人进行了心血管疾病危险因素调查[年龄45～80岁，平均（3.28 ± 6.25）岁，男性患者占所有患者的57.8%]，主要包括问卷调查、体格检查及血液学检查等，其中打鼾调查主要包括打鼾时间、次数及憋醒情况。将与打鼾相关的3个指标综合考虑后，计算出打鼾的严重程度，并分析了其与心血管疾病危险因素的关系。 结果 男性人群中打鼾率较女性高（62.0%、51.0%，P=0.003），且重度及极重度打鼾率也较女性高。随着打鼾的严重程度增加，体质量指数、血肌酐及尿酸等心血管疾病危险因素逐渐升高（趋势P均＜0.05），而高密度脂蛋白胆固醇逐渐降低（P=0.001）。另外，随着打鼾的严重程度增加，高血压患病率及收缩压也逐渐升高，但无统计学意义（趋势P=0.063，0.08）。 结论 成都地区中老年城镇人群的打鼾率较高，且男性高于女性。另外，随着打鼾的严重程度增加，心血管疾病危险因素也逐渐升高。这提示我们在临床工作中，对于打鼾的患者需要加强心血管疾病危险因素的筛查及干预，以期减少它的发生发展。
Trans-radial access (TRA) has been a common approach to percutaneous coronary intervention (PCI). Comparing with trans-femoral access (TFA), TRA is used as an alternative approach for PCI with less local complications, higher comfort level, and better outcome. In recent years, TRA has been paid more and more attention in peripheral vascular interventions. We reviewed recent developments in peripheral vascular intervention using TRA, with detail summary of the effectiveness, safety, limits, and future developments of it, aiming to improve the understanding and performance of TRA in interventionalists to benefit patients.
The ability of quickscan(QS)to assess haemodynamically significant lesions in the iliac and femoro-popliteal arteries was studied.Quickscan was prospectively and independently compared to intra-arterial digital subtraction angiography(IADSA)of the iliac and femoro-popliteal arteries.In 176 patients 757 arterial segments were evaluated.A QS frequency ratio of 1:3 or greater had a sensitivity of 88%,a specificity of 94% and accuracy of 92% in detecting stenosisgt;5O% diameter(67% area)reduction as shown on IADSA.In the detection of occlusion,QS had a sensitivity of 91%,specificity of 95% and accuracy of 94%.There was significant correlation between area reduction found by QS and the calf/brachial pressure index(CBI)(r=-0.77,Plt;0.01).Thirty-seven patients underwent an angioplasty based on QS finding alone.All 37 were successful.The authors conclude that quickscan can provide an inexpensive,quick and non-invasive screening technique for the routine initial assessment of peripheral vascular disease.The results indicate that an agreement with angiography which is as good as duplex scanning.It has potential to replace angiography for workup prior to surgical or catheter intervention,in the assessment of the success of the procedure and its continuing follow-up.

Methods By Searching the CBM database in Chinese and Medline database in English, we collected the related articles and picked out the frequency of keywords, authors and core administrations, and built the matrix of keywords and authors. Finally we completed the visualized network by Ucinet. Results We successfully obtained the visualization of this subject. Chinese network contained three parts: evidence-based medicine, therapy and nursing, while English network also contained three parts: evidence-based medicine, therapy and treatment outcome. In the authors′ visualized network, Chinese authors had less cooperation and looser relationship compared with their counterparts overseas. The core administrations in china located in outstanding universities, and developed countries had the dominated roles in the world. Conclusions The development trend of evidence-based cardiovascular medicine in china is good, but still has some limitations compared with overseas studies. More emphasis should be put on strengthening core-area researching and research plan adjustment.
It has been found that the incidence of cardiovascular disease in patients with lower limb amputation is significantly higher than that in normal individuals, but the relationship between lower limb amputation and the episodes of cardiovascular disease has not been studied from the perspective of hemodynamics. In this paper, numerical simulation was used to study the effects of amputation on aortic hemodynamics by changing peripheral impedance and capacitance. The final results showed that after amputation, the aortic blood pressure increased, the time averaged wall shear stress of the infrarenal abdominal aorta decreased and the oscillatory shear index of the left and right sides was asymmetrically distributed, while the time averaged wall shear stress of the iliac artery decreased and the oscillatory shear index increased. The changes above were more significant with the increase of amputation level, which will result in a higher incidence of atherosclerosis and abdominal aortic aneurysm. These findings preliminarily revealed the influence of lower limb amputation on the occurrence of cardiovascular diseases, and provided theoretical guidance for the design of rehabilitation training and the optimization of cardiovascular diseases treatment.
Objective To investigate the clinical characteristics of prepapillary and preretinal vascular loops. Methods The clinical manifestation, results of the fundus fluorescein angiography, and the prognosis of 20 cases(24 eyes) with prepapillary and preretinal vascual loops were analyzed retrospectively. Results 66.7% of prepapillary and preretinal vascular loops were involved in one eye, and 95.8% of vascular loops were located within one optic disc diameter. There were different configuration types of the vascular loops. Among 20 cases(24 eyes) of the vascular loops, 70.8%(17 eyes) were arterial, 12.5%(3 eyes) were venous, and 16.7%(4 eyes) were both arterial and venous. 62.5% of eyes with prepapillary and preretinal vascular loops were associated with other congenital and developmental anomalies of retinal vascular vessels. Conclusion Most PRVL are arterial and superior to the optic disc. The serious distortion of the vascular loops may result in disturbance of blood flow in artery and retinal hemorrhage, which cause visual loss. (Chin J Ocul Fundus Dis, 1999, 15: 9-11)
Cardiovascular disease is the leading cause of death worldwide, accounting for 48.0% of all deaths in Europe and 34.3% in the United States. Studies have shown that arterial stiffness takes precedence over vascular structural changes and is therefore considered to be an independent predictor of many cardiovascular diseases. At the same time, the characteristics of Korotkoff signal is related to vascular compliance. The purpose of this study is to explore the feasibility of detecting vascular stiffness based on the characteristics of Korotkoff signal. First, the Korotkoff signals of normal and stiff vessels were collected and preprocessed. Then the scattering features of Korotkoff signal were extracted by wavelet scattering network. Next, the long short-term memory (LSTM) network was established as a classification model to classify the normal and stiff vessels according to the scattering features. Finally, the performance of the classification model was evaluated by some parameters, such as accuracy, sensitivity, and specificity. In this study, 97 cases of Korotkoff signal were collected, including 47 cases from normal vessels and 50 cases from stiff vessels, which were divided into training set and test set according to the ratio of 8 : 2. The accuracy, sensitivity and specificity of the final classification model was 86.4%, 92.3% and 77.8%, respectively. At present, non-invasive screening method for vascular stiffness is very limited. The results of this study show that the characteristics of Korotkoff signal are affected by vascular compliance, and it is feasible to use the characteristics of Korotkoff signal to detect vascular stiffness. This study might be providing a new idea for non-invasive detection of vascular stiffness.
