1.Pharmacological management of migraine
Chinese Journal of Practical Internal Medicine 2001;0(06):-
Pharmacological management of migraine should be evidence-based and individualized,combined with patient's education and non-pharmacological management.For acute therapy,simple or combination analgesics (non-steroidal anti-inflammatory drugs) or migraine specific drugs (ergotamines and triptans) are recommended and should be administrated following the concept of stratification or stepwise treatment.For preventive therapy,flunarizine,antidepressant (amitriptyline),antiepileptics (valproic acids and topiramate),and beta-blockers (propranolol and metoprolol) are drugs of first choice and should be chosen individually.Prophylaxis therapy should be evaluated for 4~8 weeks and last for 3~6 months whenever it is effective.
2.Hyperglycemia and stroke
International Journal of Cerebrovascular Diseases 2009;17(1):37-40
Hyperglycemia has direct and indirect impact on the occurrence and develop-ment of stroke. At present, hyperglycemia is considered as an independent risk factor for stroke. Hyperglycemia directly involves in cellular and vascular injury through activating polyol pathway, forming advanced glycosylation end product, activating protein kinase C and the hexosamine pathway. Moreover, hyperglycemia involves in vascular injury through the indirectly pathway such as lipid metabolism, glycosylated hemoglobin and insulin. Controlling hyperglycemia may effectively reduce the incidence of stroke and improve the prognosis in patients with stroke.
3.Imaging features of acute small subcortical infarcts: comparison of large artery atherosclerotic and small artery disease stroke
International Journal of Cerebrovascular Diseases 2011;19(7):520-524
Objective To investigate the differences in neuroimaging between large artery atherosclerosis and small subcortical infarction (SSI). Methods The consecutive hospitalized patients with acute SSI were divided into large atherosclerotic stroke group and small-artery occlusive stroke group according to the evidence-based etiolologic classification of ischemic stroke (the SSS-TOAST criteria). The neuroimaging features between the two groups were compared.Results A total of 118 patients with SSI were recruited. Seven patients with cardiogenic cerebral embolism were excluded from the study. Three were stroke of other determined etiology and 7 were cryptogenic stroke. Twenty-six patients in the large artery atherosclerotic stroke group had new infarcts (3.69 ± 5. 79), 50% of them were multiple lesions, mainly a half oval in the center (P <0. 01); 75 patients in the small-artery occlusive stroke group had new infarcts (1.08 ±0. 51), only 3 (3.7%) were mltiple lesions, and they were in the different artery territories.Compared to the large atherosclerotic stroke group, the white matter lesions was more severe in the small-artery occlusive stroke group (P =0. 04), and most of them were accompanied by silent infarction (P =0. 012). Conclusions The large atherosclerotic SSI was mostly multiple infarcts in a half oval in the center, while the small artery occlusive SSI was mostly single infarct, and was usually accompanied by severe white matter lesions and silent infarction.
4.Pharmacotherapy of Poststroke Aphasia
International Journal of Cerebrovascular Diseases 2008;16(12):917-920
Stroke is the most common cause of aphasia. Traditional speech-language therapy remains the mainstay treatment of aphasia, however, its efficacy is uncertain. Although a number of studies have been carried out to investigate the role of pharmacological agents in the treatment of aphasia, the conclusions are controversial, This article reviews the state of pharma-colotherapy for poststroke aphasia.
5.Statins and Acute Ischemic Stroke
International Journal of Cerebrovascular Diseases 2008;16(3):189-192
An increasing numaber of clinical trials have confimed the cholesterol-independent effects of statins.Recent clinical observations have found that using statins before the onset of ischemic stroke and during the acute stage can greatly lessen the severity of neurological defi-cits,reduce the mortality,and improve the prognosis;and that for patients with long-term statius treatmem,who withdraw the drug abruptly,may aggravate stroke lesions,and increase the risk of relapse.Although the use of statius may slightly increase the risk of bleeding,undoubtedly,the use of statins has become one of the most important approaches in the prevention and treatment of ischemic stroke.
6.Evaluation of the prevalence of chronic kidney disease and the risk factors in patients with acute stroke
International Journal of Cerebrovascular Diseases 2009;17(6):428-433
Objective To investigate the prevalence of chronic kidney disease (CKD) in patients with acute stroke and the risk factors and prognostic characteristics in these patients.Methods A total of 270 consecutive hospitalized patients with acute stroke was recruited, and their CKD was evaluated transversally. Various risk factors and short-term prognosis of 53 patients with CKD whose National Institutes of Health Stroke Scale (NIHSS) scores were similar at admission among the 270 patients with stroke were compared to those of 106 patients without CKD. CKD was defined as glomerular filtration rate (GFR) < 60 ml/(min·1.73 m2) and (or) random urinary albumin-to-creatinine ratios (ACR) > 30 mg/g, and continued for more than 3 months. GFR was estimated according to the simplified Modification of Diet in Renal Disease (MDRD) equation, The modified Rankin Scale (mRS) was used to evaluate the shortterm prognosis. Results The prevalence of CKD in these patients was 19.6%, and most of them were early-and middle-stage CKD. The proportions of the histories of hypertension (81.13%), diabetes mellitus (33.96%), and stroke (45.28%) in patients with CKD were significantly higher than those in patients without CKD (64.15%, 18.86% and 27.36%,respectively, all P<0.05). The mean levels of systolic pressure (151.74±20.98 mm Hg) and low density lipoprotein (3.03±0.96 mmol/L) in patients with CKD were significantly higher than those in patients without CKD (systolic pressure was 144.44±21.13 mm Hg, and low density lipoprotein was 2.75±0.76 mmol/L, all P<0.05). In addition, the levels of erythrocytes sedimentation rate(median, 39 mm/h), high sensitive C-reactive protein (median,5.12 mg/L) and parathyroid hormone (81.01±26.78 pg/ml) were significantly higher than those in patients without CKD (they were 20 mm/h, 3.36 mg/L, and 46.95±24.63 pg/ml,respectively, all P<0.05). There was a changing trend in low serum calcium and high serum phosphorus in patients with CKD. The proportion of the patients whose mRS score ≥ 3 at 3 months after the onset in patients with CKD was significantly higher than that in patients without CKD (66.03% vs 46.23%, P<0.05). The mortality at 3 months (9.43%) also had an increasing tendency (P=0.073). Conclusions The prevalence of CKD was higher among the stroke population, and most of them were early-and middle-stage CKD. The stroke patients with CKD had more risk factors and worse prognosis than those without.
7.Intracerebral hemorrhage after intravenous recombinant tissue plasminogen activator for acute cerebral infarction
International Journal of Cerebrovascular Diseases 2010;18(2):113-118
Intravenous recombinant tissue plasminogen activator (rtPA) thrombolysis is the most effective therapy for acute ischemic stroke. Its most serious complication is symptomatic intracerebral hemorrhage. The overall incidence reported in the literature is 6%. It is correlated with the wascular injury and the increased vascular permeability. Some clinical features, imaging and laboratory tests can predict the risks of the complication of intracerebral hemorrhage. The mortality and disability are very high in patients with the complications of intracerebral hemorrhage after thrombolytic therapy, and their prognosis is very poor. This article reviews the classification, incidence, predictive factors, and prognosis of intracerebral hemorrhage after thrombolysis.
8.The factors predicting early efficacy of intravenous thrombolysis with atleplase in acute ischemic stroke
Chinese Journal of Internal Medicine 2012;51(10):781-783
Objective To analyze the factors affecting on early efficacy of intravenous thrombolysis with atleplase.Methods The clinical data of 100 acute cerebral infarction patients treated by intravenous thrombolysis with atleplase were retrospectively analyzed.The patients were divided into early effective group and ineffective group,whieh assessed by National Institute of Health Stroke Scale (NIHSS) with criteria of whether there were > 3 or not at 24 hours after therapy.Univariate analysis and multivariate logistic regression analysis were used to determine the differences of clinical data between the two groups.Results Univariate analysis revealed that the early improvement was significantly associated with favorable outcome at 3 month (P =0.000).Multivariate logistic analysis revealed that the systolic pressure at baseline was moderately positively associated with early improvement (OR 1.031,95% CI 1.008-1.056,P =0.009).Conclusion Moderately lower baseline systolic pressure is associated with early improvement after thrombolytic therapy which is associated with favorable outcome at 3 month.
