Acute renal artery occlusion (ARAO) is a rare clinical entity. Typical clinical presentations of ARAO are non-specific and include acute lumbar or abdominal pain coexisting with nausea, vomiting and fever. Peripheral emboli are the major cause of ARAO, predominantly arising from cardiac diseases. Other, relatively frequent causes of ARAO include atherosclerosis, trauma, dissection or renal artery aneurysms. 相似文献

Stellate ganglion blockade (SGB) protects patients from focal cerebral ischemic injury, and transection of the cervical sympathetic trunk (TCST) in a rat model can mimic SGB in humans. The purpose of this study was to investigate the mechanisms underlying the neuroprotective effects of TCST on neuronal damage in the hippocampus in a rat model of middle cerebral artery occlusion (MCAO) in an attempt to elucidate the neuroprotective effects of SGB. The modified method of Zea Longa was used to establish the permanent MCAO model. Male Wistar rats were randomly divided into three groups: sham-operated group, MCAO group, and TCST group. The animals in TCST group were sacri- ficed 48 h after TCST which was performed after the establishment of the MCAO model. Proteins were extracted from the ipsilateral hippocampus and analyzed by two-dimensional difference gel electropho- resis (2D-DIGE) and peptide mass fingerprinting (PMF). The levels of N-ethylmaleimide-sensitive fac- tor (NSF) were measured as well. The results showed that 11 types of proteins were identified by 2D- DIGE. The expressions of eight proteins were changed both in the sham-operated and TCST groups, and the expressions of the other three proteins were changed in all three groups. Moreover, the expres- sion of NSF was higher in the TCST group than in the MCAO group but lower in the MCAO group than in sham-operated group. The ratio of NSF expression between the MCAO group and sham- operated group was -1.37 (P〈0.05), whereas that between the TCST group and MCAO group was 1.35 (P〈0.05). Our results imply that TCST increases the expression of NSF in the hippocampus of adult rats with focal cerebral ischemia, which may contribute to the protection of the injured brain. Our study pro- vides a theoretical basis for the therapeutic application of SGB to patients with permanent cerebral ischemia. 相似文献

Background Recently,studies have disclosed soluble CD40 ligand (sCD40L) during atherosclerosis development and plaque destabilization.The objective of the present study was to test the hypothesis that sCD40L levels are higher in acute coronary syndrome (ACS) patients with a greater extent of angiographic coronary involvement.Methods This cross-sectional study examined ACS patients who underwent coronary angiography by measuring their sCD40L levels.In order to estimate the serum levels of sCD40L,10 ml of peripheral venous blood was drawn within 24 hours of admission.sCD40L levels were measured using an enzyme-linked immunosorbent assay (ELISA,RapidBio,West Hills,CA,USA).Demographic data,presence of concomitant diseases,ACS characteristics,and angiographic findings were evaluated.A review of medical records and patient interviews were conducted to assess coronary risk factors.And the severity of coronary artery disease was evaluated using the Gensini score index.Results Two hundred and eighty-nine patients were included in the study,of whom 186 were male,with an average age of 64.1±10.0 years.Median sCD40L levels were 1.7 ng/ml (0.3-7.3 ng/ml) and Gensini scores were 50 (0-228).After adjusting for demographic variables and cardiovascular risk factors,the Gensini score was associated with the natural logarithm of the sCD40L level (Coefficient b=0.002,95% CI 0.000-0.003,P=0.029).Conclusion sCD40L levels were independently associated with angiographic severity of coronary artery disease in patients with ACS. 相似文献

Background Balanced steady-state free precession MR angiography (b-SSFP MRA) has shown great promise in diagnosing renal artery stenosis (RAS) as a non-contrast MR angiography (NC-MRA) method. However, results from related studies are inconsistent. The purpose of this meta-analysis was to assess the accuracy of b-SSFP MIRA compared to contrast-enhanced MR angiography (CE-MRA) in diagnosing RAS. Methods English and Chinese studies that were published prior to September 4, 2013 and that assessed b-SSFP MRA diagnostic performance in RAS patients were reviewed. Quality of the literature was assessed independently by two observers. The statistical analysis was adopted by the software of Meta-Disc version 1.4. Using the heterogeneity test, a statistical effect model was chosen to calculate different pooled weighted values. The receiver operator characteristic (ROC) space and Spearman correlation coefficient were to explore threshold effect. Sensitivity analysis and the publication bias were performed to demonstrate if the pooled estimates were stable and reliable. We produced forest plots to calculate the pooled values and corresponding 95% confidence interval (Cl) of sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR), and constructed a summary receiver operating characteristic curve (SROC) to calculate the area under the curve (AUC). Results A total of 10 high quality articles were used in this meta-analysis. The studies showed a high degree of heterogeneity. The "shoulder-arm" shape in the ROC plot and the Spearman correlation coefficient between the log(SEN) and Iog(1-SPE) suggested that there was a threshold effect. Sensitivity analysis demonstrated that the actual combined effect size was equal to the theoretical combined effect size. The publication bias was low after quality evaluation of the literature and the construction of a funnel plot. The pooled sensitivity was 0.88 (95% CI, 0.83- 相似文献

Fewer than 300 patients with primary pulmonary artery sarcoma have been reported since 1923,when it was first described by Mandelstamm.1 The diagnosis of pulmonary artery sarcoma is difficult,and misdiagnosis as chronic pulmonary embolism often occurs.Herein,we reported a case of primary pulmonary artery chondrosarcoma.So far as we know,this patient served as the first case ever reported to receive computed tomography pulmonary angiography (CTPA),gadolinium enhanced magnetic resonance imaging (MRI),and positron emission tomography/computed tomography (PET/CT) before surgery.By these means,the utility of different imaging modalities for pulmonary artery sarcoma was well demonstrated.Keywords:primary pulmonary artery chondrosarcoma; computed tomography pulmonary angiography;magnetic resonance imaging; positron emission tomography 相似文献

Background Outcomes in patients requiring coronary artery bypass graft (CABG) surgery have been improved with devices such as the intra-aortic balloon pump (IABP).Good coronary collateral circulation (CCC) has been shown to reduce mortality in patients with coronary artery disease (CAD).We aimed to investigate whether poor preoperative CCC grade is a predictor of in-hospital mortality in CABG surgery requiring IABP support.Methods Fifty-five consecutive patients who were undergoing isolated first time on-pump CABG surgery with IABP support were enrolled into this study and CCC of those patients was evaluated.Results Twenty-seven patients had poor CCC and 28 patients had good CCC.In-hospital mortality rate in poor CCC group was significantly higher than good CCC group (14 (50%) vs.4 (13%),P=0.013).Preoperative hemoglobin level (OR:0.752; 95% CI,0.571-0.991,P=0.043),chronic obstructive pulmonary disease (OR:6.731; 95% CI,1.159-39.085,P=0.034) and poor CCC grade (OR:5.750; 95% CI,1.575-20.986,P=0.008) were associated with post-CABG in-hospital mortality.Poor CCC grade (OR:4.853; 95% CI,1.124-20.952,P=0.034) and preoperative hemoglobin level (OR:0.624; 95% CI,0.476-0.954,P=0.026) were independent predictors of in-hospital mortality after CABG.Conclusion Preoperative poor CCC and hemoglobin are predictors of in-hospital mortality after CABG with IABP support. 相似文献

Coronary artery anomalies (CAAs) are present at birth, but are usually asymptomatic and are found during coronary angiography or multi-slice computed tomography (MSCT) examinations. Their prevalence is less than 1.3% based published series.1'2 The most common coronary anomaly is separate origin of the left anterior descending coronary artery (LAD) and left circumflex coronary artery (LCX) from the left sinus of the Valsalva. The second most common anomaly is the origin of the LCX artery from the right coronary artery (RCA) or right sinus of the Valsalva. We present two cases of coronary artery anomalies: one is the left main coronary artery (LMCA) arising from the proximal RCA, the other is the LAD originating from the proximal RCA. 相似文献

This study was aimed to establish a stable animal model of left ventricular hypertrophy (LVH) to provide theoretical and experimental basis for understanding the development of LVH. The abdominal aorta of male Wistar rats (80-100 g) was constricted to a diameter of 0.55 mm between the branches of the celiac and anterior mesenteric arteries. Echocardiography using a linear phased array probe was performed as well as pathological examination and plasma B-type natriuretic peptide (BNP) measurement at 3, 4 and 6 weeks after abdominal aortic constriction (AAC). The results showed that the acute mortality rate (within 24 h) of this modified rat model was 8%. Animals who underwent AAC demonstrated significantly increased interventricular septal (IVS), LV posterior wall (LVPWd), LV mass index (LVMI), cross-sectional area (CSA) of myocytes, and perivascular fibrosis; the ejection fraction (EF), fractional shortening (FS), and cardiac output (CO) were consistently lower at each time point after AAC. Notably, differences in these parameters between AAC group and sham group were significant by 3 weeks and reached peaks at 4th week. Following AAC, the plasma BNP was gradually elevated compared with the sham group at 3rd and 6th week. It was concluded that this modified AAC model can develop LVH, both stably and safely, by week four post-surgery; echocardiography is able to assess changes in chamber dimensions and systolic properties accurately in rats with LVH. 相似文献

Coronary artery fistula (CAF), an uncommon congenital heart disease, often results in myocardial ischemia. In the last two decades, there are some reports about interventional treatment of CAF,4-6 but few on transcatheter treatment of multiple CAFs. With different interventional procedures, we treated successfully two cases of percutaneous closure of two multiple CAFs which were confluent at the distal ends. 相似文献

R urrent pregnancy loss (RPL) is defined as two or ore failed clinical pregnancies. Up to 50% of RPL does not have a clear etiology.1 Increased resistance to blood flow in the uterine arteries has been found in women with unexplained RPL, and even greater resistance has been detected in women with RPL and auto-antibodies.2 However, vascular changes and pregnancy outcomes after the treatment for RPL patients with abnormal uterine artery flow remain poorly studied. 相似文献

OBJECTIVE: To investigate the anti-inflammatory, anti-oxidative stress, and adipokine-ameliorating effects of Liuwei Dihuang (LWDH), a traditional Chinese herbal formula, in obese rats. METHODS: After 2 weeks of acclimation with free access to regular rodent chow and water, obese-prone-caesarean-derived (OP-CD) rats were fed a modified AIN-93G diet containing 60% energy from fat. Treatment was performed twice daily by gavage feeding with 500, 1 500, or 3 500 mg/kg body weight LWDH suspended in water (n=12 rats per group). Twelve obese-resistant-CD (OR-CD) rats were fed the atherogenic diet and gavaged with water, and served as the normal control. Blood biomarkers of inflammation, oxidative stress and adiponectin were measured post-sacrifice and used to determine the treatment effect of LWDH and assess the suitability of OR/OP-CD rats for studying these parameters. RESULTS: After 9 weeks of treatment, LWDH lowered serum C-reactive protein (CRP) and tumour necrosis factor-α (TNF-α) levels. Serum interleukin-6 (IL-6) levels showed a tendency towards reduction, but were not significantly different from the OP-CD control. Liver superoxide dismutase (SOD) activity was increased in response to all three doses of LWDH, while the levels of reduced (GSH) and oxidized glutathione (GSSG) and thiobarbituric acid reactive substances (TBARS) were unchanged. Serum adiponectin levels were increased in response to oral administration of LWDH at the dose of either 500 or 1 500 mg/kg body weight. In addition, comparisons between OR-CD and OP-CD rats revealed differential, and for some biomarkers, conflicting characteristics of high-fat diet-fed OP-CD rats in reference to obese human subjects in terms of inflammatory and oxidative stress biomarkers and circulating adiponectin levels. CONCLUSION: The results show, for the first time, the anti-inflammatory, anti-oxidative stress and adiponectin-ameliorating effects of LWDH in obese rats.
