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 observe rehabilitation and functional prognosis of patients suffered from brain infarction of acute phase complicated by depression. Method We selected 38 cases of acute brain infarct complicated with depression disorder as depression group, 40 cases of non-depression patient admitted at the same period were selected as non depression group.Antidepressants drugs administration and rehabilitation therapy were performed.We evaluated patients according to functional independence measure(FIM)of Chinese edition. HAMD grading comparison was carried out in depression group. Result Before treatment,two groups score nearly the same,compared with pretreatment. After treatment,patients in depression group and non depression group showed significant improvement esp non-depression group (P<0.01).11 cases with severe depression in the depression showed no changes in FIM score before and after treatment. Conclusion Compared with non-depression patients,functional recovery of patients with depression following brain infarction of acute stage is much slower,especially for patients with severe depression. 展开更多

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

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

The effect of transcranial magnetic stimulation (TMS) on the neurological functional recovery and expression of c-Fos and brain-derived neurotrophic factor (BDNF) of the cerebral cortex in rats with cerebral infarction was investigated. Cerebral infarction models were established by using left middle cerebral artery occlusion (MCAO) and were randomly divided into a model group (n=40) and a TMS group (n=40). TMS treatment (2 times per day, 30 pulses per time) with a frequency of 0.5 Hz and magnetic field intensity of 1.33 Tesla was carried out in TMS group after MCAO. Modified neurological severity score (NSS) were recorded before and 1, 7, 14, 21, and 28 day(s) after MCAO. The expression of c-Fos and BDNF was immunohistochemically detected 1, 7, 14, 21, and 28 day(s) after infarction respectively. Our results showed that a significant recovery of NSS (P〈0.05) was found in animals treated by TMS on day 7, 14, 21, and 28 as compared with the animals in the model group. The positive expression of c-Fos and BDNF was detected in the cortex surrounding the infarction areas, while the expression of c-Fos and BDNF increased significantly in TMS treatment group in comparison with those in model group 7, 14, 21, and 28 days (P〈0.05) and 7 14, 21 days (P〈0.01) after infarction, respectively. It is concluded that TMS has therapeutic effect on cerebral infarction and this may have something to do with TMS's ability to promote the expression of c-Fos and BDNF of the cerebral cortex in rats with cerebral infarction. 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
