ABSTRACT
Poststroke cognitive impairment (PSCI) is a common complication after ischemic stroke, which seriously affects the recovery of neurologic function and lowers the quality of daily life of patients. In a considerable portion of patients, the PSCI is reversible. This article reviews the influencing factors of cognitive impairment after ischemic stroke, including genetic predisposition, demographic factors, lifestyles, clinical manifestations, imaging findings and drug administration, etc. to provide references for prevention and intervention of PSCI.
ABSTRACT
Objective:To explore the clinical characteristics and complementary tests of a Chinese patient with central mixed phenotype acute leukemia and improve the awareness and diagnosis of MPAL among clinicians.Methods:Retrospectively analyzed a patient's clinical feature, laboratory examination, diagnosis and literature review who had headache as the first symptom and finally diagnosed with MPAL.Results:A 59-year-old female presented with recurrent headaches and can not relieved, at last , was confirmed as mixed phenotype acute leukemia by flow cytometry of cerebrospinal fluid、immunophenotyping and molecular biology of bone marrow. Remission was achieved after chemotherapy for lymphoid and myeloid leukemia.Conclusion:Patients with an unclear diagnosis of central nervous system disease, leukemia should be considered, and cerebrospinal fluid flow cytology and bone marrow biopsy should be refined.
ABSTRACT
@#Objective To analyze the association between serum homocysteine (Hcy),white matter hyperintensity (WMH) and cerebral microbleeds (CMBs).Methods 309 patients were divided into CMBs group (n=116) and control group (n=193),lobar CMBs group (n=90) and deep CMBs group (n=26),minor CMBs group (n=78) and major CMBs group (n=38),low-level Hcy group (n=158) and high level Hcy group (n=151) according to the quantity and site of CMBs and the median levels of Hcy.Results The levels of Hcy,glucose,creatinine,the total score of Fazekas scale,systolic pressure and pulse pressure difference were higher in CMBs group than control group (P<0.05);Male,systolic pressure and the total score of Fazekas scale were independent risk factors of CMBs by Logical regression (P<0.05).The scores of Fazekas scale were higher in lobar CMBs group than deep CMBs group (P<0.05);Serum Hcy,the scores of Fazekas scale were related to quantity of CMBs (P<0.05).Conclusions The serum Hcy was partcipated in the process of CMBS.The severity of WMH was correlation with lobar CMBs may play a prediction role in CMBs.
ABSTRACT
ObjectiveTo study the relation ship between progressive cerebral infarction and thyroid hormone level,and analyze the risk factors of progressive cerebral infarction.MethodsThe thyroid hormone,triglyceride esters and fasting glucose levels of 48 patients with progressive cerebral infarction,138 patients with non-progressive cerebral infarction and 60 healthy subjects as control group were measured.ResultsCompared with the patients with non-progressive cerebral infarction,serum T3 of patients with progressive cerebral infarction was lower( P ＜0.05),and the levels of triglyceride ( TG),C-reactive protein ( CRP),and fasting blood glucose were higher ( all P ＜ 0.01 ).ConclusionPatients with progressive cerebral infarction were in a low level of thyroid hormones,and the increasing levels of TG,CRP,and fasting blood glucose were risk factors for progressive cerebral infarction.
ABSTRACT
The naturally occuring antibiotic resistance in twentyseven strains from 7 different serotypes of Bacillus sphaericus was investigated. The antibiotics used in this experiment are Streptomycin, Ampicilline, Tetracycline, Chloramphenicol, Kanamycin, Erythromycin, Qingdamycin, Midecamycin, Ribostamycin, Acriflavin, Rifampicin, Sulphanilamide and Azide. All strains are resist to streptomycin and azide at higher concentration and chloramphenicol at lower concentration. Most of strains are resist to tetracycline at lower concentration.
