Objective:To investigate the feasibility and safety of submaximal balloon dilation and to perform small-diameter stent for symptomatic carotid artery severely stenosis before coronary artery bypass grafting(CABG).Methods:From January 2016 to December 2019, 30 patients of the Department of Neurointervention in Beijing Anzhen Hospital with symptomatic carotid artery stenosis(≥70%) and the left main trunk or triple-vessel of coronary artery disease were analyzed retrospectively. General information, clinical characteristics, and imaging data of all cases were collected. All patients underwent submaximal balloon dilation and small-diameter stent implantation. Preoperative comorbidities or risk factors included hypertension 23 cases(76.7%), diabetes 10 cases(33.3%), hyperglycemia 14 cases(46.7%), moking 13 cases(43.3%). Left main trunk disease 6 cases(20.0%), three-vessels disease 24 cases(80.0%), mitral regurgitation 1 case(3.3%), stable angina 25 cases(83.3%), myocardial infarction 8 cases(26.7%), cerebral infarction 24 cases(80.0%) and transient ischemia attack(TIA) 6 cases(20.0%) caused by ipsilateral carotid artery stenosis. The median National Institutes of Health Stroke Scale(NIHSS) score was 2(0-3), and the median modified Rankin Scale(mRS) score was 1(0-1) before the operation. The mean interval between carotid artery intervention and CABG was(23.4±8.2)days.Results:29 cases(96.7%, 29/30) underwent CAS-CABG operation successfully. In one case of carotid artery extreme tortuosity, the emboli protective device could not place the distal carotid artery. In the operative procedure, 27 cases(90.0%, 27/30) underwent with 3mm diameter balloon, only 3 cases(10.0%) with 3 mm balloon after pre-dilatation with 2 mm diameter balloon because of severely high-grade stenosis(99%). 25 cases(83.3%) with 7mm diameter stents and 5 cases(16.7%) with 6 mm diameter stents, including 22 cases(73.3%) with a closed-cell stent and 8 cases(26.7%) with an open-cell stent. In the perioperative period, the heart rate of two patients was lower than 50 BPM during operation and returned to normal after using atropine immediately. Another patient presented with chest tightness during interventional therapy. TNI elevation was examined urgently. After oxygen inhalation and intravenous infusion of Nitroglycerin, the patient's symptoms improved rapidly. No cardiac and cerebrovascular complications occurred during the perioperative period of CABG, no cardiac-related complications occurred within 30 days of follow-up, one case of TIA and 1 case of cerebral infarction. After intensive anti-platelet aggregation and lipid-lowering treatment, two patient's symptoms improved. There were no death cases in all patients during carotid artery interventional therapy, perioperative CABG and 30-day follow-up. Thirty days later, we performed a clinical follow-up of 23 cases, median 4.5(3.0-7.9) months, mRS Score Median 1(0-1). One patient presented with TIA, any patient had no symptoms of the cardiac or nervous system. Image follow-up of 17 cases, median 3.5(2.8-4.5) months, carotid artery ultrasound showed in-stent restenosis(stenosis rate>50%) in 1 case, the patient was asymptomatic restenosis, continue treatment of aggressive anti-platelet and lipid-lowering drugs.Conclusion:Submaximal balloon dilation and performing small-diameter stent for symptomatic carotid artery severely stenosis before CABG is safe and feasible, which could not only reduce the incidence of vagus reflex resulted in acute coronary syndrome during carotid artery stenosis intervention but also morbidity of acute ischemic stroke events during CABG.

Objective: Previous studies have demonstrated a strong association between carotid artery stenosis (CAS) and coronary artery stenosis disease (COAS). However, prior evaluated methods are non-invasive examinations. This study was aimed to access the relationship between CAS and COAS by the means of angiography. Methods: This is a single-center, retrospectively reviewed study based on digital subtraction angiography (DSA) of carotid artery and coronary artery angiography (CAG). We collected a total of 231 patients undergoing DSA and CAG at the same-day between June 2013 and May 2015. The patients were stratified according to the degree of CAS and COAS, mild stenosis <50%, moderate stenosis 50-69%, severe stenosis 70-99%, occlusion 100%. The correlation of CAS with COAS, as well as the risk factors, was analyzed. Results: A total of 231 patients was enrolled in this study, male 71.9% (166/231). The age ranges from 32 to 80, mean age 60.06 ± 9.98. Of these patients, 79 patients were severe CAS and 128 patients were severe COAS. Statistical analysis demonstrated that the independent risk factors of severe COAS ≥70%, were age, sex, previous cerebral infraction, coronary heart diseases, and coronary artery surgery. CAS was associated with COAS (Spearman r = 0.333, P < 0.01). The more serious the CAS, the more involved COAS (Kendall's tab-b = 0.294, p < 0.01). Conclusions: The DSA confirmed CAS was associated with CAG confirmed COAS. The heavier the CAS is, the more the number of the affected coronary artery.
Objective To analyze the risk factors and etiological classification in young patients with cerebral infarction.Methods From January 2010 to December 2018,5 120 patients with acute cerebral infarction were admitted to neurology ward of Beijing Anzhen Hospital,Capital Medical University.Among them,337 young patients and 337 matched (1:1) middle-aged and old patients were selected.Age,sex,smoking,alcohol consumption,comorbidities of diabetes,dyslipidemia,hypertension,heart disease,stroke,hyper-homocysteine (Hcy) and sleep apnea syndrome were recorded.Risk factors and etiological types of cerebral infarction were analyzed.Results Prevalence rates of cerebral infarction risk factors in young patients from high to low were male,hypertension,smoking history,hyperlipidemia,history of alcohol consumption,hyper-Hcy,diabetes,heart disease history,stroke/family history,hyperuricemia,sleep apnea syndrome and migraine.Prevalence rates of cerebral infarction risk factors in middle-aged and old patients from high to low were hyperlipidemia,hypertension,male,smoking history,diabetes,heart disease history,stroke/family history,history of alcohol consumption,hyper-Hcy,hyperuricemia,sleep apnea syndrome and migraine.Proportions of male,smoking history,history of alcohol consumption and hyper-Hcy in young patients were higher while the proportions of hypertension,diabetes,hyperlipidemia,heart disease history,stroke/family history were lower than those in middle-aged and old patients [81.9% (276/337) vs 70.3% (237/337),64.4% (217/337) vs 49.3% (166/337),38.3% (129/337) vs 23.7% (80/337),37.4% (126/337) vs 18.4% (62/337);66.2% (223/337) vs 78.9% (266/337),25.2%(85/337) vs 40.4% (136/337),49.3% (166/337) vs 81.0% (273/337),16.3% (55/337) vs 37.7% (127/337),12.5% (42/337) vs 32.6% (110/337)] (all P < 0.05).Atherosclerosis type of cerebral infarction took the highest ratio among young patients;small artery occlusion type accounted for 32.0% (108/337);unexplained type accounted for 12.8% (43/337);cardiogenic type accounted for 10.1% (34/337).Males took a large ratio in young patients with unexplained type of cerebral infarction.Among middle-aged and old patients,atherosclerosis type and small artery occlusion type of cerebral infarction accounted for high ratios.Conclusions Young men are more likely to suffer from cerebral infarction than women.Cerebral infarction in young adults are associated with various risk factors.Atherosclerosis type of cerebral infarction is the most common etiological type.It is of great significance for the prevention and treatment of young stroke to strengthen health education on smoking and alcohol cessation,promote healthy diet and raise the awareness of stroke risk factors among young people.
1876年,James Paget 首先报道6例局限性骨重建异常的病例,后命名为 Paget 骨病,也称畸形性骨炎或变形性骨炎(osteitis deformans)。其以骨重建增加、骨肥大、骨结构异常为特征,可导致骨痛、畸形和骨折发生。严重者可出现心血管和神经系统等并发症[1]。当累及骨盆时,部分患者可能被误认为血管瘤,目前国内外未见类似报道。本文报道1例患者误诊为髂骨血管瘤10余年,治疗效果欠佳,后经本科确诊为 Paget 骨病,本文予以报告。

Objective To explore the value of intraoperative color Doppler flow imaging in carotid endarterectomy.Methods Twenty-one patients with serious internal carotid stenosis underwent carotid endarterectomy(CEA).The intraoperative color Doppler flow imaging was applied to confirm the positions of carotid plaques,the dimensions of pathological changes,and the flaps or the thrombosis in carotid artery.According to Panetton's standards,the outcomes of color Doppler flow imaging were classified as normal,minor or significant abnormal.Results Fourteen strip high echo were found in 9 patients after operation,including 12 minor abnormalities(intimal flaps less than 3 mm) and 2 significant abnormalities(one was the implanted adventitia in artery,another was a thrombus with strip form).These 2 significant abnormalities were managed with operation,while the other 12 minor abnormalities were not treated but then recovered 3 days after operation.Conclusion Application of color Doppler flow imaging during CEA helps to confirming the position of carotid plaques,observing dimensions and changes and the level of stenosis,as well as discovering lesions and complications,therefore benefits to decrease stroke and death after operation.
Objective To investigate the secondary prevention of ischemic stroke drug treatment compliance and impact of anti-platelet drug compliance factors.Methods From August 2007 to September 2007,ischemic stroke or TIA patients who were admitted into internal medicine of neurology wards of 21 Hospitals in Beijing,a total of 541 recurrent stroke patients who were analyzed,retrospectively.Results There were 541 recurrent stroke patients.Uses of antiplatelet,antihypertension,antidiabetic and lipid-lowering therapy 58.4%,82.3%、85.3% and 14.2%,respectively.Age≥60(P=0.011),retirement (P=0.021),history of stroke (P<0.001),history of angina (P=0.001),history of myocardial infarction (P=0.037) and history of hypertension(P=0.016)was associated with anti-platelet drug compliance.Conclusions The present investigation has revealed a low drug compliance for secondary prevention of ischemic stroke,suggesting that the current status of secondary prevention of recurrent stroke is far from ideal.
Objective: A series of research works had proven that high-resolution magnetic resonance imaging (MRI) was an effective tool to identify the morphological appearance of atherosclerotic vulnerable plaque. We performed further study to compare ex vivo vascular morphology with MRI and histological examination using the specimens of carotid endarterectomy and femoral artery (FA) prosthetic reconstruction, and described the detailed histology and immunohistochemistry features ofplaque.Methods: Eight consecutive patients (five males, mean age 67.4 years) who were recruited into our study had high-grade stenosis or occlusion of carotid artery and FA (70 to 100%). Four patients accepted carotid endarterectomy and others underwent FA prosthetic reconstruction.Results: The high level of accuracy was shown in classification of the plaque type. The sections of plaques detected by MRI were classified as follows: 12 (22.2%) were modified American Heart Association (AHA) type III, 11 (20.4%) were type IV-V, 26 (48.2%) were type VI and 5 (9.3%) were type VII. According to the histological observations, the overall accurate rate by MRI showed a high level accuracy of 90.7% (49/54). Immunohistochemistry of cellular components in plaque shoulder demonstrated that CD68-positive macrophages were strongly dominated along the arterial wall. Reduced expression of smooth muscle actin (SMA)-positive smooth muscle cells were detected in the fibrous cap of atheroma. CD31 stain showed the increased presence of CD31-positive neomicrovessels.Conclusions: Atherosclerosis is a systematic disease that can involve whole body vascular beds. Noninvasive high-resolution MRI will provide useful information in morphological studies of the arterial walls and classification of the plaque type.
Objective To determine if adopt ABCDE strategies can maintain high medication coincidence rates after discharge from hospital.Methods From August 2007 to Dec 2007,a total of 1166 ischemic stroke or TIA patients were admitted into neurology wards of 21 hospitals in Beijing. Status of secondary prevention of stroke was analyzed by software SPSS 11.5,focusing on the compliance rate of medication in antiplatelet,antihypertension,antidiabetes and lipid-lowering therapy in hospital and discharge from hospital.Results There were 541 recurrent stroke patients, antiplatelet therapy rate in them was 58.4% ,antihypertension,antidiabetes and lipid-lowering therapy rates were 82.3%,85.3% and 14.2% respectively.There were 1166 patients discharged. Of them,1012 completed 90-days and six-months follow-up,and 981 completed one-year follow-up.The compliance rate of medication in antiplatelet,antihypertension,antidiabetes and lipid-lowering therapy was kept at a high level.Conclusion The status of secondary prevention of recurrent stroke can not be optimistic.Adopting ABCDE treatment strategy to carry out standard intervention for the admitted ischemic stroke/TIA patients significantly narrows the secondary prevention gap between evidence-based medicine and clinical practice,and makes medication compliance rate at a high level after discharge.
Objectives To investigate the internal association between apoptosis and Bax/Bcl-2 expression, and explore the relationship between the gene expression and atherosclerotic plaque stability. Methods Totally 8 human femoral artery and 5 human carotid plaque specimens obtained during endarterecctomy were fixed,decalcified,cut at 4 mm intervals and routinely processed for HE sections.All blocks were divided into stable plaques and unstable plaques,from which 40 plaques were respectively chosen and studied immunohistochemically.Computer aided planimetry was used to measure the positive area of different cells and gene expression.Results The percentages of cells positive for caspase-3,Bax,Bcl-2 in unstable plaques and stable plaques were respectively 27.4%and 15.4%(P<0.05);20.9%and 15.1%(P<0.05);5.9%and 10.3%(P<0.01).Conclusion There are higher apoptosis indexes in unstable plaques and apoptosis promotes the development of unstable plaques.Bax/Bcl-2 is relative to apoptosis in plaques and Bcl-2 plays a role in blocking the development of plaque.
细胞凋亡,是指细胞在一定的生理或病理条件下,遵循自身程序自己结束其生命的程序性死亡.它是有一系列酶参与、由基因控制的一个主动的、高度有序的死亡过程,表现为细胞浆浓缩,染色质固缩,最后形成多个凋亡小体而被吞噬.对生物机体的正常发育及自身稳定具有极其重要的作用.细胞凋亡功能的失控、抑制或增加均会引起机体平衡失调,是多种疾病产牛的重要原因之一.
