Stroke in progression, infection of herpes virus and neurologic impairment inhibited with antivirus druggery / 中国组织工程研究

ABSTRACT

BACKGROUND: Stroke in progression(SIP) accounts for 26% -43% of cerebral infarction. It is a common clinical stroke subtype. However, there are no effective treatments to stop the progress with higher mortality rate and invalid rate. More attentions have been paid for multiple risk factors of cerebrovascular diseases during precaution and treatment. But the study on relationship between infection and stroke occurrence, and the inhibited clinical event with antivirus druggery is just at the beginning.OBJECTIVE: To investigate the correlation between clinical SIP characteristics and herpes virus(HSV) infection, and provide the clues to the SIP diagnosis and treatment and early rehabilitation.DESIGN: Case-control study based on patients.SETTING: Department of neurology in a university hospital and a microbiological department in a university.PARTICIPANTS: Totally 47 patients with progressive stroke hospitalized in Department of Neurology, the Second Hospital of Hebei Medical University during April 2001 to March 2002[21 males, 26 females; aged from 15 to 78 years, mean age of(53.12 ± 2.45) years] . There were 43 cases of limb paralysis (92%), 7 cases of aphasia, 4 cases of consciousness disturbance, 1 case of epileptic seizure, 1 case of hemianopia, 5 cases of ataxia, and 24 cases of dizziness. The diagnosis of cerebral infarction was confirmed with CT and/or MRI. The patients clinical pregresively aggravated over more than 72 hours from the stroke onset. And it was not able to stop the aggravation of the situation with conventional treatment. The patients with embolism and reversible ischemic neurological deficit(RIND), cerebral hemorrhage, hemorrhagic infarct were excluded; Patients with other severe diseases such as coronary heart disease, cardiac atrium fibrillation, severe diabetes, hypertension, and the history of illness more than 5 years were excluded. Totally 193 patients were selected as control group with non-cerebrovascular disease, included headache, insomnia, neck and shoulder pain[ 100 males, 93 females, aged from 26 to 60 years,mean age of(42.23 ±9.29)].of the Fourth Scholarship Meeting of Cerebrovascular Diseases in China in tected by MRI, 44 cases detected by magnetic resonance angiography(MRA), 4cases detected by digital subtraction angiography (DSA), and 8 cases detected levels of IgM of human cytomegalovirus(HCMV) and herpes virus(HSV) in serum of 47 patients with progressive stroke and 193 patients without cerebrovascular disease were detected by dot immunogold labeling staining (IGLS); Stromatin PP65 antigen of HCMV in marrow cell were detecting by of the situation with the conventional treatment. PFA 250 mL(3.0 g) was given once a day from 14 to 21 days and dexamethasone 5 - 10 mga day for 3 to 7 days.after treatment with antivirus druggery.dot low-density plaques in cortex or subcortex of cerebral lobes, were found in were found positive in 91% of the patients and the level of IgM in patients PFA was effective.of cerebral lobes, and stenosis or occlusion in cerebral arteries or major infection and progressive stroke.
