The anxiety scale is scored by a professional psychiatrist. There are a total of 14 items, including anxiety, nervousness, fear, insomnia, cognitive function, depressed mood, somatic anxiety, sensory system, etc. The total score ≥ 29 points may be severe;≥21 points, there must be obvious;≥14 points, there must be anxiety;a score of more than 7 may indicate anxiety. If the score is less than 7, there are no anxiety symptoms. All patients within 24 to 72 hours, complete the head examination magnetic resonance, computerized calculation of the DWI sequence images, according to the results of the calculation to superimpose the image of the lesion, image reconstruction in space, and carry out Binarization, defining the value of lesions as 1, and the value of non as 0. All lesions are superimposed into one image and integrated. The relationship between the lesions in this superimposed image and anxiety after cerebral infarction was analyzed. <strong>Results: </strong>The lesions were basically concentrated around the lateral ventricle, and they were mainly concentrated around the lateral ventricle. <strong>Conclusion:</strong> Patients with acute cerebral infarction in the lateral ventricle or basal ganglia are more prone to post-stroke anxiety. This has a certain evaluation value for the prognosis of future cerebral infarction, and has a certain understanding of the exploration of complications, and has a certain understanding of the exploration of complications. 展开更多

We report on silent brain infarction (SBI) and leuko- araiosis (LA) of 23 patients with clinically diagnosed “first-ever” acute ischemic lacunar stroke. The lacunar syndromes were pure motor hemiparesis (10), pure sensory syndrome (2), ataxic hemiparesis (3), dysarthria clumsy hand syndrome (3), and sensory- motor deficit (5). Nineteen out of the 23 patients presented with completed strokes on arrival to the hospital, and 4 (17%) developed evolving-stroke within 24 hours of stroke onset. A lacune corresponded to the acute stroke could be found in all patients on brain magnetic resonance imaging (MRI), and in 18 (78%) on brain computed tomography (CT). MRI showed additional subclinical or asymptomatic “silent brain infarctions or lacunes” (SBI) in 19 (83%) of 23 patients, and leuko-araiosis (LA) of moderate to severe degree (> grade 2) was present in 61% of patients although dementia was absent. Hypertension is the risk factor in 78% of cases followed by diabetes mellitus, smoking, and elevated plasma cholesterol level. Independence of the types of lacunar syndromes, patients with hypertension and diabetes mellitus are associated with high grade LA. None with normal blood pressure and plasma glucose had grade 3 or grade 4 LA (p < 0.05). In conclusion, evolving-stroke occurs in one- fifth of patients with “first-ever” lacunar infarct within the first 24 hours of stroke onset. SBI was found in 83% of cases. Hypertension and diabetes mellitus are associated with additional SBI and high grade LA. The severity of leuko-araiosis per se dictates the cerebrovascular risks. 展开更多

Objective: To study the prevalence of silent cerebral infarction in Type II diabetes mellitus. Patients and Methods: The study was a prospective on 80 patients recruited from neurology, endocrine outpatient clinics. Patients were type II diabetics as described by the American Diabetes Association, 2011 criteria. All patients underwent full metabolic profiles to diagnose diabetes mellitus and MRI brain scans to detect cerebral infarction. Results: Silent cerebral infarctions were detected in 60% of patients (48/80 patients) predominately along periventricular white matter area and subcortical areas (Basal ganglia, Thalamus). Conclusion: Asymptomatic Type II diabetes mellitus patients could have vascular cerebral changes without neurological symptoms. MRI brain scans could be recommended as routine diagnosis (if possible) for early cerebral infarct detection in type II diabetic patients. 展开更多

Objective: To study the mechanisms of acupuncture in treatment of acute cerebral infarction. Methods: 90 SD rats were randomly divided into normal control group (n=10), model group (n=40) and electroacupuncture (EA) group (n=40). Shuigou (GV 26), bilateral Neiguan (PC 6) and Zusanli (ST 36) were stimulated with EA for 20 min. Acute cerebral infarction (ACI) was produced by blocking blood flow of the cerebral middle artery. Changes of β EP content in the brain tissue after ACI and EA were detected by radioimmunoassay (RIA). Results: 24 hour after ACI, plasma β EP content increased significantly to 1120.41±33.79 ng/L from 401.72±266.47 ng/L before ACL. While after acupuncutre, the increased β EP content lowered evidently in comparison with that of model group but was close to that of normal group. Conclusion: Acupuncture may adjust the neuroendocrine disturbance in rats with acute cerebral infarction to minimize the injury of the brain tissue. 展开更多

Objective: To explore the influence of ginkgolide combined with edaravone on the brain function of elderly patients with acute cerebral infarction and its preventive effect on ischemia reperfusion injury. Methods: A total of 126 patients with acute cerebral infarction who were treated in Dazhou Central Hospital between February 2016 and May 2017 were divided into the control group (n=67) and ginkgolide group (n=59) according to different therapies. Control group received routine intravenous thrombolysis + edaravone therapy, and ginkgolide group received routine intravenous thrombolysis + edaravone + ginkgolide therapy. The differences in brain function and nerve ischemia reperfusion injury extent were compared between the two groups. Results: At T1 and T2, serum nerve function indexes NT-proBNP and NSE levels of ginkgolide group were lower than those of control group whereas BDNF levels were higher than those of control group;serum inflammatory mediators MCP-1, NF-κB, CRP and TNF-α levels were lower than those of control group;serum apoptosis molecules caspase-3 and Bax levels were lower than those of control group whereas Bcl-2 levels were higher than those of control group. Conclusion: Ginkgolide combined with edaravone therapy on the basis of intravenous thrombolysis can effectively optimize the brain function and alleviate the ischemia reperfusion injury caused by inflammatory response and apoptosisis in elderly patients with acute cerebral infarction. 展开更多

Objective:To observe the influence of tirofiban on the troponin, brain natriuretic peptide, heart function in patients with Acute Myocardial Infarction after PCI and provide scientific basis for treatment of acute myocardial infarction.Methods:A total of 100 cases of hypertensive cerebral hemorrhage patients in our hospital were selected and randomly divided into 2 groups: the control group (50 cases) and the observation group (50 cases). The conventional treatment of PCI was performed on both groups. Tirofiban injection was given to the observation group on the basis of conventional treatment. cTnI, BNP and echocardiography parameters (LVEF, LVEDD, LVESD) were detected before and after treatment.Results:The comparison of cTnI in the two groups before operation was not statistically significant. cTnI in the 2 groups increased 12 h and 24 h after operation. But the cTnI in observation group (0.10±0.23) ng/mL decreased more significantly than that in control group (0.24±0.31) ng/mL, the difference was considered to be statistically significant. The comparison of BNP in the two groups before operation was not statistically significant. BNP in the 2 groups decreased obviously 7 d and 30 d after operation. BNP in observation group decreased more significantly than that in control group and the difference was considered to be statistically significant LVEF in the observation group increased significantly compared with that in control group 7 d after operation. The comparison of LVEDD, LVESD were not considered to be statistically significant. LVEDD and LVESD in the observation group were lower than that in control group obviously 30 d after operation. While the LVEF in the observation group was still higher than that in the control group. The comparsion was considered to be statistically significant.Conclusion:Tirofiban can improve the troponin, brain natriuretic peptide, heart function in patients with Acute Myocardial Infarction after PCI. It can also decrease the heart injury as well as helping the recovery of heart function. 展开更多

Neuroprotection by ischemic preconditioning has been confirmed by many studies, but the precise mechanism remains unclear. In the present study, we performed cerebral ischemic pre- conditioning in rats by simulating a transient ischemic attack twice (each a 20-minute occlusion of the middle cerebral artery) before inducing focal cerebral infarction (2 hour occlusion-reper- fusion in the same artery). We also explored the mechanism underlying the neuroprotective effect of ischemic preconditioning. Seven days after ocdusion-reperfusion, tetrazolium chloride staining and immunohistochemistry revealed that the infarct volume was significantly smaller in the group that underwent preconditioning than in the model group. Furthermore, vascular endothelial growth factor immunoreactivity was considerably greater in the hippocampal CA3 region of preconditioned rats than model rats. Our results suggest that the protective effects of ischemic preconditioning on focal cerebral infarction are associated with upregulation of vascu- lar endothelial growth factor. 展开更多

Previous studies have demonstrated the protective effect of hypoxic preconditioning on acute cerebral infarction, but the mechanisms underlying this protection remain unclear. To investigate the protective mechanisms of hypoxic preconditioning in relation to its effects on angiogenesis, we in- duced a photochemical model of cerebral infarction in an inbred line of mice (BALB/c). Mice were then exposed to hypoxic preconditioning 30 minutes prior to model establishment. Results showed significantly increased vascular endothelial growth factor and CD31 expression in the ischemic penumbra at 24 and 72 hours post infarction, mainly in neurons and vascular endothelial cells. Hypoxic preconditioning increased vascular endothelial growth factor and CD31 expression in the ischemic penumbra and the expression of vascular endothelial growth factor was positively related to that of CD31. Moreover, hypoxic preconditioning reduced the infarct volume and improved neu- rological function in mice. These findings indicate that the protective role of hypoxic preconditioning in acute cerebral infarction may possibly be due to an increase in expression of vascular endothelial growth factor and CD31 in the ischemic penumbra, which promoted angiogenesis. 展开更多

Low frequency (≤ 1 Hz) repetitive transcranial magnetic stimulation (rTMS) can affect the excitability of the cerebral cortex and synaptic plasticity. Although this is a common method for clinical treatment of cerebral infarction, whether it promotes the recovery of motor function remains controversial. Twenty patients with cerebral infarction combined with hemiparalysis were equally and randomly divided into a low frequency rTMS group and a control group. The patients in the low frequency rTMS group were given 1-Hz rTMS to the contralateral primary motor cortex with a stimulus intensity of 90% motor threshold, 30 minutes/day. The patients in the control group were given sham stimulation. After 14 days of treatment, clinical function scores (National Institute of Health Stroke Scale, Barthel Index, and Fugl-Meyer Assessment) improved significantly in the low frequency rTMS group, and the effects were better than that in the control group. We conclude that low frequency (1 Hz) rTMS for 14 days can help improve motor function after cerebral infarction. 展开更多

Blood samples were harvested from the antecubital vein of 20 fasting patients with acute cerebral infarction at 1, 7 and 15 days after onset to prepare blood platelet suspension. Fasting antecubital vein blood was collected from an additional 20 normal adults as controls. Under transmission elec- tron microscope, platelet Golgi tubules and vesicles became significantly thickened, enlarged, and irregular after acute cerebral infarction. Alpha granules in platelets significantly reduced in number, especially 1 day after cerebral infarction. Under immunoelectron microscopy, a few alpha granules aggregated around Golgi tubules and vesicles after infarction. These results suggested that platelet Golgi apparatus displayed significant morphological changes, which were possibly associated with enhanced synthetic and secretory functions of activated platelets after acute cerebral infarction. This study used Golgi apparatus blocking agent Brefeldin A to block Golgi apparatus in an aim to study the effects of Golgi apparatus on CD40L expression on the surface of activated platelets. Flow cytometry revealed that CD40L expression on activated platelet surfaces decreased significantly when Golgi apparatus was blocked, which indicated that Golgi apparatus participated in the syn- thesis and transport of CD40L to the platelet surface. 展开更多

A model of focal cerebral ischemic infarction was established in dogs through middle cerebral artery occlusion of the right side.Thirty minutes after occlusion,models were injected with nerve growth factor adjacent to the infarct locus.The therapeutic effect of nerve growth factor against cerebral infarction was assessed using the hemisphere anomalous volume ratio,a quantitative index of diffusion-weighted MRI.At 6 hours,24 hours,7 days and 3 months after modeling,the hemisphere anomalous volume ratio was significantly reduced after treatment with nerve growth factor. Hematoxylin-eosin staining,immunohistochemistry,electron microscopy and neurological function scores showed that infarct defects were slightly reduced and neurological function significantly improved after nerve growth factor treatment.This result was consistent with diffusion-weighted MRI measurements.Experimental findings indicate that nerve growth factor can protect against cerebral infarction,and that the hemisphere anomalous volume ratio of diffusion-weighted MRI can be used to evaluate the therapeutic effect. 展开更多

Studies have confirmed that low-frequency repetitive transcranial magnetic stimulation can decrease the activity of cortical neurons, and high-frequency repetitive transcranial magnetic stimulation can increase the excitability of cortical neurons. However, there are few studies concerning the use of different frequencies of repetitive transcranial magnetic stimulation on the recovery of upper-limb motor function after cerebral infarction. We hypothesized that different frequencies of repetitive transcranial magnetic stimulation in patients with cerebral infarction would produce different effects on the recovery of upper-limb motor function. This study enrolled 127 patients with upper-limb dysfunction during the subacute phase of cerebral infarction. These patients were randomly assigned to three groups. The low-frequency group comprised 42 patients who were treated with 1 Hz repetitive transcranial magnetic stimulation on the contralateral hemisphere primary motor cortex (M1). The high-frequency group comprised 43 patients who were treated with 10 Hz repetitive transcranial magnetic stimulation on ipsilateral M1. Finally, the sham group comprised 42 patients who were treated with 10 Hz of false stimulation on ipsilateral M1. A total of 135 seconds of stimulation was applied in the sham group and high-frequency group. At 2 weeks after treatment, cortical latency of motor-evoked potentials and central motor conduction time were significantly lower compared with before treatment. Moreover, motor function scores were significantly improved. The above indices for the low- and high-frequency groups were significantly different compared with the sham group. However, there was no significant difference between the low- and high-frequency groups. The results show that low- and high-frequency repetitive transcranial magnetic stimulation can similarly improve upper-limb motor function in patients with cerebral infarction. 展开更多

BACKGROUND: Acupuncture can improve motor function in patients with cerebral infarction, and activate brain glucose metabolism in relevant brain areas. However, the association between encephalic region activation and acupuncture, as well as the clinical significance of activation remain unclear. OBJECTIVE: Through the use of positron emission tomography-computed tomography (PET-CT), acute cerebral infarction patients were analyzed for global cerebral metabolism, cerebral infarction focus, peripheral edema, and pyramidal tract pathway changes, which were directly related to clinical symptoms. The influence of resuscitating acupuncture on cerebral glucose metabolism was analyzed in patients with acute cerebral infarction in basal ganglia. DESIGN, TIME AND SETTNG: Randomized, controlled, clinical trials were performed from March 2007 to October 2008 at the PET-CT Center of the General Hospital of Tianjin Medical University, China. PARTICIPANTS: Twelve patients with acute basal ganglia infarction were recruited from the First Affiliated Hospital of Tianjin University of Traditional Chinese Medicine, the Second Affiliated Hospital of Tianjin University of Traditional Chinese Medicine, Tianjin Chinese Medicine Hospital, and Affiliated Hospital of Medical College of Chinese People's Armed Police Force. METHODS: The cerebral infarcted patients were randomly assigned to acupuncture and control groups. In addition to routine treatment, the acupuncture group was treated by acupuncture at the main acupoints for resuscitation [Neiguan (PC 6), Renzhong (DU 26), and Sanyinjiao (SP 6)], while the control group received routine treatment. MAIN OUTCOME MEASURES: Before and after treatment, patients with acute cerebral infarction were evaluated for global brain, cerebral infarction focus, and surrounding edema and glucose metabolism in encephalic region of pyramidal tract conduction by 18-labeled fluorodeoxyglucose for PET-CT imaging. RESULTS: The resuscitating acupuncture therapy can significantly activate the metabolism of global brain, infarction center and surrounding edema in patients with cerebral infarction in basal ganglia, also has effects on the activation of glucose metabolism in the encephalic regions of pyramidal tract pathway (P 〈 0.05). CONCLUSION: Resuscitating acupuncture was superior to routine treatment for significantly activating glucose metabolism in patients with acute cerebral basal ganglia infarction. 展开更多
