Predictors of restenosis after carotid endarterectomy and carotid artery stenting / 国际脑血管病杂志

Carotid artery stenosis is an important cause of ischemic stroke. Carotid endarterectomy and carotid artery stenting are the effective methods for treating carotid artery stenosis, but postoperative restenosis remains a challenge. The pathogenesis of postoperative restenosis is currently not fully understood. However, multiple factors, including biomarkers, imaging features, and surgical related factors, have been proven to be associated with postoperative restenosis and can predict the occurrence of postoperative restenosis. This article reviews the predictors of restenosis after carotid endarterectomy and carotid artery stenting.

Internal carotid artery bifurcation aneurysms / 国际脑血管病杂志

Internal carotid artery bifurcation aneurysm is relatively rare in clinical practice. It locates at the bifurcation of the internal carotid artery, with numerous branches and perforating vessels running through it. Whether endovascular treatment or craniotomy clipping, it is necessary to ensure the patency of the branches and perforating vessels. There are very few systematic reports on internal carotid artery bifurcation aneurysms. This article summarizes its definition, epidemiology, formation and rupture mechanisms, clinical features, and imaging features, with a focus on explaining its classification and treatment.

Analysis of risk factors for the rupture of small intracranial aneurysms by four?dimensional CT angiography / 中华放射学杂志

Objective Electrocardiographic (ECG) gated 4?dimensional CT angiography (4D?CTA) was performed to analyze the morphological characteristic differences between ruptured and unruptured intracranial aneurysms less than 5 mm to predict the rupture risk of small intracranial aneurysms. Methods A total of 118 patients with intracranial aneurysms less than 5 mm who underwent 4D?CTA examinations in our hospital from May 2014 to May 2017 were retrospectively analyzed. The whole study population was divided into ruptured group and unruptured group. Seventy?two patients were in the ruptured group and 46 patients were in the unruptured group. Original scanning data were reconstructed to produce 20 data sets of cardiac cycles with 5% time intervals. In addition, 20 groups of images and dynamic graphs were generated using three?dimensional software. We concluded the convex was point of impulse if small bubble or small pointed convex could be found in continuous three or more images at the same location. The morphological characteristics and clinical features of the two groups of aneurysms were firstly analyzed by univariate analysis, and then the meaningful indicators were analyzed by logistic regression, and the optimal diagnostic cutoff values were calculated using ROC curves. Results Univariate analysis showed that women, smoking history, location of aneurysm at the bifurcation, pulsation point, aspect ratio (AR) and size ratio (SR) were statistically significant different between the two groups of small aneurysms (P<0.05), but age, hypertension, type 2 diabetes, family history, history of multiple aneurysms, history of drinking, location, size, neck and tumor height had no significant differences between the two groups (P>0.05). Multivariate regression analysis showed that pulsation point (odds ratio=8.843, 95% confidence interval: 2.800—27.925) and large SR value (odds ratio=4.484, 95% confidence interval: 1.094—18.385) were independent risk factors for the aneurismal rupture. when the SR value was greater than 1.65, the area under the ROC curve was 0.832, the sensitivity to diagnose the risk of small aneurysm rupture was 76%, and the specificity is 70%. Conclusion The occurrence of pulsation point and SR value greater than 1.65 are independent predictors of the risk of intracranial aneurysm rupture less than 5 mm.

Application value of transcranial Doppler combined with indocyanine green angiography and FLOW 800 in carotid endarterectomy / 中华神经医学杂志

Objective To investigate the hemodynamic monitoring and clinical significance of transcranial Doppler (TCD) combined with indocyanine green (ICG) fluorescence angiography and FLOW 800 in carotid endarterectomy (CEA).Methods Forty-eight patients with extracranial carotid atherosclerotic stenosis underwent CEA in our hospital from October 2015 to September 2018 were chosen to our study. The mean blood flow velocity (Vm) of the middle cerebral artery (MCA) was monitored by TCD throughout the operation. The intraoperative blood pressures were adjusted according to the monitoring results, and the average blood Vm of the narrowed arteries was measured using TCD probe before and after artery temporary occlusion. ICG fluorescence angiography and FLOW 800 were used to monitor vascular morphology and patency simultaneously.Results One patient, who was observed to have severe stenosis by TCD, ICG fluorescence angiography, and FLOW 800 after arteries temporary occlusion, showed significantly improved by multimodal monitoring after re-suture; one patient showed external carotid artery occlusion by ICG fluorescence angiography and FLOW 800 had noexternal carotid artery occlusion; other 46 patients showed no carotid artery stenosis and good intracranial perfusion by TCD, ICG fluorescence angiography, and FLOW 800 after initial suture. Two patients developed ischemic stroke (IS) after CEA, and both of them were recovered after conservative medical treatment for two weeks without any neurological dysfunction; two patients had cerebral hyperperfusion syndrome (CHS), and both of them relieved after blood pressure control three d after treatment; one patient had subcutaneous hematoma in the operation area, and the hematoma was gradually absorbed after conservative treatment; the rest patients recovered well. All patients were followed up for 4-6 months after CEA, and CT angiography showed that carotid artery stenosis was relieved; CT perfusion imaging and TCD examinations showed that cerebral perfusion was significantly improved as compared with those before operation.Conclusion Intraoperative TCD combined with ICG fluorescence angiography and FLOW 800 can effectively monitor the intracranial and extracranial blood flow of intraoperative carotid artery, which is of great significance in reducing the risk of IS and CHS during carotid endarterectomy.

Inhibitory effects and mechanism of Triticum aestivum on OVA-induced anaphylaxis in mice / 中华微生物学和免疫学杂志

Objective@#To investigate the inhibitory effects and mechanism of Triticum aestivum (TA) on anaphylaxis in ovalbumin (OVA)-sensitized mice.@*Methods@#Twenty-five female BALB/c mice were randomly divided into five groups (n=5), including control group, OVA group, 100 mg/kg TA group, 200 mg/kg TA group and DEX (dexamethasone) group. OVA (20 μg) and aluminum hydroxide (1 mg) were dissolved in 100 μl of PBS solution and injected into the abdominal cavity of each experimental mouse, while the mice in the control group were injected with 100 μl of 0.9% normal saline. All mice were given drinking water. The above processes were repeated two weeks later, and different concentrations of experimental drugs were diluted in 1% CMC (carboxymethyl cellulose) solution to feed mice. Allergic symptoms and behaviors of each mouse were scored in the process of feeding. On the 12th day after first sensitization, mice in the control and experimental groups were subcutaneously injected in the auricle with 20 μl of 0.9% saline solution and OVA, respectively. The thickness of each mouse′s auricle was measured 6 and 24 hours later. Histopathologic changes in auricle tissues were observed by hematoxylin-eosin(HE) staining 24 hours later. The mice were euthanized by cervical dislocation in the 6th week after first sensitization. Abdominal aorta serum samples were collected and tested for specific inflammatory cytokines (IgE, IgG1, TNF-α, IL-4) and anti-OVA antibodies (IgE, IgG1) by ELISA. ELISA and RT-PCR were used to detect the expression of IFN-γ, IL-4, IL-5, IL-12 and IL-13 after spleen lymphocytes were stimulated with different concentrations of drugs.@*Results@#Both the score of allergic symptoms and behavior and the thickness of the auricle of the OVA group were the highest among all groups (P<0.05). A TA dose-dependent decrease was found in both of the two parameters, which was confirmed by histopathological analysis. ELISA results showed that the plasma levels of IgE, IgG1, IL-4 and TNF-α in the experimental groups were significantly higher than those in the control group, but all of them were decreased in a TA dose-dependent manner. TA at the high concentration of 200 mg/kg was similar to DEX in inhibiting the expression of IgE and TNF-α. RT-PCR results showed that Th1 cytokines (IFN-y and IL-12) in the experimental groups increased significantly as compared with those in the control group (P<0.05). Expression of IFN-y and IL-12 was not significantly affected by TA at various concentrations, but markedly inhibited by DEX. The levels of Th2 cytokines (IL-4, IL-5 and IL-13) in the experiment groups were significantly higher than those in the control group (P<0.05). Compared with the OVA group, the levels of IL-4, IL-5 and IL-13 were significantly reduced in TA groups, especially in the TA 100 μg/ml group in which the expression of the three cytokines was decreased by about 60%, 18% and 20%, respectively.@*Conclusion@#TA helps to maintain immune balance by selectively inhibiting the expression of Th2 cytokines (IL-4, IL-5, IL-13), IgE and IgG and not influencing Th1 cytokines (IFN-γ and IL-12). It has an anti-allergic effect as it effectively suppresses allergic responses. This research provides both theoretical and experimental basis for further development of novel anti-anaphylactic treatment with TA.

Objective To investigate the value of three dimensional time-of-flight (3D-TO)F) and three dimensional fast imaging employing steady state acquisition (3D-FIESTA)sequences in evaluation on spatial relationship among trigeminal nerve,facial nerve and peripheral vessels before microvascular decompression(MVD)with 3.0 T MR.Methods Data of MRI of 36 patients with trigeminal neuralgia (TN) and 31 with hemifacial spasm (HFS) before MVD were analyzed retrospectively.The intra-observer agreement for the spatial relationship among trigeminal nerve,facial nerve and adjacent blood vessels were observed.The differences of occurrence rates of neurovascular compression (NVC) of symptomatic side and asymptomatic side in TN and HFS patients were compared.Taking surgical results as the gold standards,the diagnostic efficacy for neurovascular relationships of symptomatic side with 3D-TOF and 3D-FIESTA sequences were calculated.Results The consistency between two observers in assessing relationship of trigeminal nerve,facial nerve and adjacent blood vessels of symptomatic and asymptomatic was good (all Kappa≥0.75,all P＜0.001).In both of TN and HFS patients,the occurrence rates of NVC of symptomatic side were significantly higher than those of asymptomatic side (x2=26.13,20.81,both P＜ 0.001).The accuracy,sensitivity,specificity,positive predictive value and negative predictive value of 3D-TOF and 3D-FIESTA sequences in displaying relationship of trigeminal nerve and vascular was 97.22％ (35/36),97.06％ (33/34),100％ (2/2),100％ (33/33)and 66.67％ (2/3),respectively,of relationship between facial nerve and vascular was 93.55％ (29/31),96.55％ (28/29),50.00％ (1/2),96.55％ (28/29) and 50.00％ (1/2),respectively.Conclusion 3D-TOF and 3D-FIESTA sequences can clearly display the spatial relationship of nerve and adjacent vessels,therefore providing imaging evidences for MVD.

Value of MR diffusion tensor imaging in the assessment of the changes of trigeminal nerve and its correlation with the degree of vascular compression / 中华放射学杂志

Objective To investigate the value of MR diffusion tensor imaging(DTI)in assessment of the microstructural changes of the trigeminal nerve,and analyze it's correlation with the degree of vascular compression. Methods Thirty-four patients with trigeminal neuralgia from November 2015 to April 2017 were retrospectively analyzed in this study.And they were treated by microvascular decompression(MVD). There were 11 cases of gradeⅠ,16 cases of gradeⅡand 7 cases of gradeⅢaccording to the severity of the contact between nerves and vessels during the operation. All of them were scanned with three dimensional time-of-flight(3D-TOF)sequences, three dimensional fast imaging employing steady state acquisition(3D-FIESTA)sequences and DTI before undergoing surgical decompression. According to the preoperative MR scans,the trigeminal nerves were divided into the healthy side without neurovascular contact (25 cases) and the healthy side with a neurovascular contact (9 cases).The DTI parameters of the trigeminal nerve,including the anisotropic fraction(FA)and the ADC values were obtained.Comparison of the FA and ADC values of the trigeminal nerve between the different stages of the affected side was performed with single factor analysis of variance, and the paired samples t test was used to compare the difference of FA and ADC values of bilateral trigeminal nerve. The difference of FA and ADC values between the asymptomatic side with or without vascular contact was compared with independent sample t test. Spearman correlation analysis was used to evaluate the correlation between DTI parameters and the degree of compression. Results The FA values of patients with grades Ⅰ,ⅡandⅢwere 0.311±0.009, 0.308±0.007 and 0.299±0.009 respectively,and there was significant difference among different levels(F=5.269,P<0.05).The ADC values of the three grades were(2.298 ± 0.309)×10-3,(2.214 ± 0.175)×10-3and (2.259 ± 0.248)×10-3mm2/s respectively, showing no statistically significant difference(F=0.402,P>0.05). The FA values of bilateral trigeminal nerves in healthy side without neurovascular contact and in healthy side with neurovascular contact were statistically significant (t=-32.528,-25.178,P<0.05). There was significant difference in the ADC value of bilateral trigeminal nerves in the group without neurovascular contact(t=2.162,P<0.05).There was no statistically significant difference in the ADC values of bilateral trigeminal nerves in the healthy side of the neurovascular contact group(P>0.05).There were no statistically significant differences in the FA and ADC values between the two groups on the healthy side of the trigeminal nerve(P>0.05).The FA value was negatively correlated with the degree of vascular compression (r=-0.453,P<0.05),while the ADC value was not correlated with the degree of vascular compression(P>0.05). Conclusion DTI imaging can be used to evaluate the degree of trigeminal nerve injury. More obvious vascular compression leads to lower FA value.
